Definitions

  • ABSTRACT A plurality of modular wall units are constructed on a base area within a temporary shelter removably positioned on the base area. The temporary shelter is then moved from the base area. With the shelter removed from the base area, the wall units are first lifted vertically and moved horizontally for lowering into position on a building foundation.
  • Buildings are commonly constructed by laying bricks to form vertical walls on a foundation.
  • the bricklayers cannot work during inclement weather and this considerably delays completion of a building.
  • the cost of buildings is also increased due togsuch delays.
  • An arrangement for constructing buildings includes a large concrete slab providing a base area.
  • the base area may be a part of the building foundation itself or may be constructed nearby.
  • the slab providing the base area is preferably at a distance from the building site which is not greater than the swing span of a hoisting crane used to move the modular wall units into position.
  • a temporary shelter including a roof is removably positioned on the base area.
  • the temporary shelter may have canvas or other types of sidewalls to provide an enclosure.
  • Workmen construct a plurality of rows of modular brick wall units on the base area within the shelter. The walls are assembled using high early setting mortar so that the wall units can be moved after a period of three days. Once the space under the temporary shelter is filled, the temporary shelter is moved away from the base area to expose the modular wall units.
  • a crane then lifts the wall units vertically from the base area and transfers them laterally over to proper position on the building foundation.
  • the wall units are then lowered into proper position on the building foundation.
  • the base area includes first and second base area portions each having an area at least as great as the area enclosed by the temporary shelter.
  • first and second base area portions each having an area at least as great as the area enclosed by the temporary shelter.
  • the slab on which the base area is formed includes attaching means for removably attaching the temporary shelter thereto so that high winds will not move the temporary shelter.
  • the temporary shelter may be mounted on rollers for horizontal shifting movement between the first and second base area portions, or it may be lifted vertically by a crane and moved laterally between the first and second base area portions.
  • Elongated horizontal guide means are positioned on the base area and the modular wall units are constructed on these horizontal guide means.
  • Spaced-apart vertical guide means extend between the horizontal guide means and the roof of the temporary shelter.
  • the modular wall units are constructed on the horizontal guide means between the spaced-apart vertical guide means.
  • the vertical guide means are removably positioned between the roof of the temporary shelter and the horizontal guide means so that they may be shifted for constructing successive rows of modular wall units.
  • the vertical guide means include telescoping inner and outer posts.
  • the inner post is biased outwardly from the outer post by springs.
  • the upper end of the inner post engages the underside of the roof of the temporary shelter with yielding force.
  • Operating means is provided for telescoping the inner tube within the outer tube against the force of the springs.
  • this operating means includes a lever pivotally connected to the outer post for pivotal movement in a vertical plane.
  • a link is pivotally connected with the lever and the inner post. Pulling downward on the lever causes a downward pulling force on the inner post through the link to telescope the inner post within the outer post against the spring force.
  • the upper end of the inner post has a flat plate member mounted thereon.
  • the flat plate member is yieldably mounted on the upper end of the inner post and can also tilt so that it will be in firm engagement with the roof of the temporary shelter even though the roof is slightly pitched.
  • Guide shoes are positionable on the horizontal guide means for properly spacing the vertical guide means.
  • the vertical guide means and shoes include cooperable sockets and projections for releasably securing the vertical guide means to the horizontal guide means.
  • the modular wall units are of brick or block and mortar construction. Each modular wall unit includes front and rear surfaces, and top and bottom edges. Each modular wall unit also has a midpoint between its top and bottom edges. Brace means is secured to the rear surface of each modular wall unit in the first row above the midpoint thereof. The brace means is secured to the base area so that the wall units cannot topple or be blown over. The brace means includes length adjustment means for adjusting the length of the brace means. Standoff means is also positioned between the brace means and the rear surface of the modular wall unit for preventing the outer end of the brace means from falling below a horizontal plane extending through the bottom edge of the wall unit. The brace means may be grasped by workmen when the wall units are being lowered into position on a building foundation. The standoff means prevents the brace means from contacting the foundation before the modular wall unit when the wall unit is lowered into position on a building foundation.

That is, crane C does not have to move on its tracks for transferring all wall units on slab B to their desired position on foundation A. Generally, this distance will be not greater than feet because that is approximately the maximum swing span of a conventional crane used in building construction. In other words, the greatest distance between a position on slab B at which a wall unit is constructed, and a position on foundation A where the furthest wall unit will be installed, is not greater than the swing span of crane C, or around 150 feet.

APPARATUS AND METHOD FOR BUILDING CONSTRUCTION BACKGROUND OF THE INVENTION This application pertains to the art of building construction and more particularly to prefabricated building construction. The invention is particularly applicable to prefabricated construction of brick walls and will be particularly described with reference thereto. I-Iowever, it will be appreciated that the invention has broader applications and may be used with other types of modular building components.
Buildings are commonly constructed by laying bricks to form vertical walls on a foundation. The bricklayers cannot work during inclement weather and this considerably delays completion of a building. The cost of buildings is also increased due togsuch delays.
Many buildings are also constructed from preformed modular building components which are constructed at a factory. Such modular components must be shipped to the site of the building. Transportation costs are extremely expensive. Delays in shipping or arrival of such components at the building site also delay completion of the building and increase costs because the workmen are idle while waiting for additional components. Breakage of such preformed building components also occurs during shipment.
It would be desirable to have building construction arrangement whereby preformed modular building components could be assembled even during inclement weather, and without requiring shipment of such components to a building site.
SUMMARY OF THE INVENTION An arrangement for constructing buildings includes a large concrete slab providing a base area. The base area may be a part of the building foundation itself or may be constructed nearby. The slab providing the base area is preferably at a distance from the building site which is not greater than the swing span of a hoisting crane used to move the modular wall units into position. A temporary shelter including a roof is removably positioned on the base area. The temporary shelter may have canvas or other types of sidewalls to provide an enclosure. Workmen construct a plurality of rows of modular brick wall units on the base area within the shelter. The walls are assembled using high early setting mortar so that the wall units can be moved after a period of three days. Once the space under the temporary shelter is filled, the temporary shelter is moved away from the base area to expose the modular wall units.
A crane then lifts the wall units vertically from the base area and transfers them laterally over to proper position on the building foundation. The wall units are then lowered into proper position on the building foundation.
In a preferred arrangement, the base area includes first and second base area portions each having an area at least as great as the area enclosed by the temporary shelter. When the area below the shelter is completely filled with modular wall units constructed on the first base area portion, the shelter is moved to the second base area portion. The shelter is again filled with modular wall units constructed on the second base area portion. By the time the second base area portion is filled, the mortar in the wall units on the first base area portion will have set sufficiently so that they can be moved 2 into position on the building. The temporary shelter is simply shifted back and forth between the first and second base area portions.
The slab on which the base area is formed includes attaching means for removably attaching the temporary shelter thereto so that high winds will not move the temporary shelter. The temporary shelter may be mounted on rollers for horizontal shifting movement between the first and second base area portions, or it may be lifted vertically by a crane and moved laterally between the first and second base area portions.
Elongated horizontal guide means are positioned on the base area and the modular wall units are constructed on these horizontal guide means. Spaced-apart vertical guide means extend between the horizontal guide means and the roof of the temporary shelter. The modular wall unitsare constructed on the horizontal guide means between the spaced-apart vertical guide means. The vertical guide means are removably positioned between the roof of the temporary shelter and the horizontal guide means so that they may be shifted for constructing successive rows of modular wall units.
In accordance with one arrangement, the vertical guide means include telescoping inner and outer posts. The inner post is biased outwardly from the outer post by springs. The upper end of the inner post engages the underside of the roof of the temporary shelter with yielding force. Operating means is provided for telescoping the inner tube within the outer tube against the force of the springs. In one arrangement, this operating means includes a lever pivotally connected to the outer post for pivotal movement in a vertical plane. A link is pivotally connected with the lever and the inner post. Pulling downward on the lever causes a downward pulling force on the inner post through the link to telescope the inner post within the outer post against the spring force.
In a preferred arrangement, the upper end of the inner post has a flat plate member mounted thereon. The flat plate member is yieldably mounted on the upper end of the inner post and can also tilt so that it will be in firm engagement with the roof of the temporary shelter even though the roof is slightly pitched.
Guide shoes are positionable on the horizontal guide means for properly spacing the vertical guide means. The vertical guide means and shoes include cooperable sockets and projections for releasably securing the vertical guide means to the horizontal guide means.
The modular wall units are of brick or block and mortar construction. Each modular wall unit includes front and rear surfaces, and top and bottom edges. Each modular wall unit also has a midpoint between its top and bottom edges. Brace means is secured to the rear surface of each modular wall unit in the first row above the midpoint thereof. The brace means is secured to the base area so that the wall units cannot topple or be blown over. The brace means includes length adjustment means for adjusting the length of the brace means. Standoff means is also positioned between the brace means and the rear surface of the modular wall unit for preventing the outer end of the brace means from falling below a horizontal plane extending through the bottom edge of the wall unit. The brace means may be grasped by workmen when the wall units are being lowered into position on a building foundation. The standoff means prevents the brace means from contacting the foundation before the modular wall unit when the wall unit is lowered into position on a building foundation.
It is a principal object of the present invention to provide an improved arrangement for constructing buildings.
It is also an object of the present invention to provide an improved method for constructing buildings.
It is another object of the present invention to provide a building construction arrangement and method which is very economical and efficient.
It is an additional object of the present invention to provide a building construction arrangement and method which enables workmen to construct building components even during inclement weather.
It is a further object of the present invention to provide an arrangement and method for prefabricating modular wall units while minimizing the danger of breakage during movement of the wall units to a building foundation.

DESCRIPTION OF A PREFERRED EMBODIMENT Referring now to the drawings, wherein the showings are for purposes of illustrating a preferred embodiment of the invention only and not for purposes of limiting same, FIG. 1 shows a' horizontal concrete slab A defining a foundation for a building. Slab A is shown rectangular in plan view and it will be recognized that the foundation may take many different shapes. Foundation A is adapted to having a plurality of modular vertical wall units assembled around the periphery thereof to define a rectangular enclosure. Another horizontal concrete slab B is laid adjacent to building foundation A.
Modular wall units constructed on slab B are moved therefrom over to building foundation A by a conventional hoisting crane C. Crane C includes a cab portion 12 and a boom 14. Cab 12 is pivotal on its supporting base to move boom 14 in the direction of arrows l6 and 18. Boom 14 is moved in the direction of arrow 16 so that it extends over the top of slab B. A modular wall unit on slab B may then be vertically raised and transferred horizontally over to building foundation A. The modular wall unit is then lowered into the desirable position onfoundation A.
In the preferred arrangement, slab B is located relative to foundation A so that all modular wall units constructed on slab B can be placed on foundation A in a single swing of boom 14 on crane C. That is, crane C does not have to move on its tracks for transferring all wall units on slab B to their desired position on foundation A. Generally, this distance will be not greater than feet because that is approximately the maximum swing span of a conventional crane used in building construction. In other words, the greatest distance between a position on slab B at which a wall unit is constructed, and a position on foundation A where the furthest wall unit will be installed, is not greater than the swing span of crane C, or around 150 feet.
Slab B has a plurality of socket members 20 embedded therein for removably attaching a temporary shelter to slab B. Slab B has a substantially horizontal plane upper surface defining a base area.
FIG. 2 shows a form of temporary shelter used for carrying out the principles of the present invention. Shelter D includes spaced-apart vertical supporting legs 24 located at the cornersof a rectangle orsquare. Beams E connect the upper ends of legs 24.
Each ibeam E includes .upper and lower flanges 26 and 28, and web struts 30 interconnecting upper and lower flanges 26 and 28. Rectangular socket members 34 which .open downwardly are welded or otherwise suitably secured tothe opposite ends of beams E. Thus, socket members 34 serve to interconnect all beams E.
The upper ends of vertical legs 24 are received in sockets 34 whichmay have closed upper ends. Suitable holes are provided through socket members 34 and the upper end portions of legs 24 for receiving bolts as at 36 to releasably secure beams E and sockets 34 to the upper end portions of legs 24. Diagonal braces as at 38 .may be welded or otherwise secured to legs 24 and bottom flanges 28 of beams E. Outer diagonal braces 40 may also be provided. Outer diagonal braces 40 have their upper ends bolted as at 42 to socket members 34. The lower ends of diagonal braces may have brackets attached thereto for removable bolting to expansion anchors positioned in holes in slab B.
A plurality of rectangular plywood panels 44 are positioned on top flanges 26 of beams E. Panels 44 preferably extend outward slightly beyond top flanges 26 of beams E. Panels 44 have a plurality of pairs of spacedapart holes therethrough adjacent top flanges 26 for receiving U-shaped clamping members 50. The legs of inverted U-shaped clamping members 50 extend through panels 44 on opposite .sides of top flanges 26 of beams E. Rectangular plate members 52 having spaced-apart holes therethrough are positioned on the leg of clamping members 50 beneath top flanges 26. Bolts 56 are then threaded onto the leg ends of clamping members 50.
At least four of clamping members 50 adjacent the corners of temporary shelter D may have hooking rings as at 58 positioned thereon prior to insertion of the legs of those clamping members through the holes in panels 44. With panels 44 assembled as described, a roof F is provided on temporary shelter D spaced vertically above base portion 22 of slab B.
Rectangular upwardly opening socket members embedded in slab B receive the bottom end portions of rectangular legs 24. Sockets 20 and the bottom portions of legs 24 have suitable holes therethrough for receiving bolts as at 60 to releasably and removably attach temporary shelter D to slab B. Suitable holes may be formed in the upper surface of slab B for receiving expansion anchors to releasably and removably secure the bottom end portions of outer diagonal braces 40 thereto.
A tent-like canvas cover member G is positioned over temporary shelter D as shown in FIG. 4. Cover member G includes an upper portion 64 completely covering roof F, and sidewall portions 66. Sidewall portions 66 may be trapezoidal in shape and have zippers or other fastening devices along their opposite edges for securing each of the four sides 66 together at their edges. Each side 66 of cover member G may also have transparent plastic panels sewn together to provide illumination within temporary shelter D. Thebottom end portions of sides 66 are looped over and sewn to provide passageways 68 for receiving elongated pipe member 70. Flexible ties 72 may be sewn or otherwise secured to the outer surface of passages 68. Eyelet members 74 may be threaded into expansion anchors positioned in suitable holes bored in slab B. Ties 72 may be secured to eyelets 74 to releasably anchor sidewalls 66 in position. During nice weather, sidewalls 66 may be rolled up and simply positioned on top of roof F. During inclement weather, sides 66 may be rolled down and secured as described.
Hooking loops 58 maybe exposed by sliding cover member G slightly. Hooks on the end portions of chains or cables 78are then receivable through hooking loops 58. All of cables 78 may be connected at a central point as at 80. Cable 82 of crane C may then be hooked to cable 78 at point 80. Crane C is then moved until the end portion of boom 14 is substantially vertically above point 80. Crane cable 82 is then reeled in for raising temporary shelter D from slab B when the releasable bolting and securing arrangements have been disconnected. Crane C may then be swung to transfer temporary shelter to another area where it is lowered into position and secured in the manner described.
It will be recognized that the temporary shelter described may take many forms. The roof of the temporary shelter may also be slightly pitched and be supported by many different beam arrangements. In actual practice, roof F of temporary shelter D will be much larger than shown for purposes of illustration. For example, roof F may be a square having 32 foot edges. Many different sizes and arrangements of temporary shelter D are possible. The size and type of temporary shelter simply depends upon the size and particular requirements of the job. lt will also be recognized that temporary shelter D may be removably secured to slab B in many different ways. For example, temporary shelter D may be mounted on wheels for rolling movement relative to slab B instead of requiring lifting thereof. Such a wheeled shelter could simply have suitable angle brackets with holes therethrough for receiving bolts which would thread into expanding anchors positioned in suitable holes in slab B. For small jobs where the weather is good, such a wheeled temporary shelter could simply be blocked without bolting or other securement to slab B if there were no danger of high winds.
In a preferred arrangement, as shown in FIG. 1, slab B includes first and second base area portions 84 and 86. First and second base area portions 84 and 86 lie on opposite sides of transverse line 88 bisecting base area 22 of slab B. Each base area portion 84 and 86 has an area at least as great as the area enclosed by temporary shelter D. Temporary shelter D may be removably positioned on first base area portion 84. Construction of prefabricated modular wall units may then be carried out within temporary shelter D on first base area portion 84. Once shelter D is filled, it may be lifted and moved over to second base area portion 86 where construction of modular wall units again proceeds. This leaves the wall units on base area portion 84 exposed for vertical lifting and transfer over onto building foundation A. Shelter D is simply transferred back and forth between first and second base area portions 84 and 86. It will be recognized that other arrangements are also possible. For example, base area 22 could simply be slightly over one and one-half times the length of temporary shelter D. Temporary shelter D could then simply be shifted or moved from one end to the other of base area 22 for exposing completed modular wall units for lifting over onto foundation A.
Instead of a separate slab B adjacent foundation A,
it will be recognized that base area 22 could be defined by the surface of building foundation A itself where room permits. For a very large building, foundation A itself may be sufficiently large to position temporary shelter D thereon for carrying out the principles of the present invention. In addition, slab B could simply be defined by a parking lot or driveway slab located adjacent foundation A.
With temporary shelter D removably positioned on first base area portion 84, an elongated substantially U-shaped channel member H is positioned thereon. Channel member H may comprise several lengths butted together to extend substantially completely across first base area portion 84 within temporary shelter D. Channel H includes a web portion 94, and spaced- apart legs 96 and 98 depending therefrom. Channel H is positioned on first base area portion 84 with web 94 facing upward, while legs 96 and 98 rest upon first base area portion 84. At least one of legs 98 of channel member H has a plurality of spaced-apart holes 102 therein.
FIGS. 9 and show a shoe used with channel H for aligning and positioning the vertical guide members. Shoe I comprises a substantially U-shaped channel member having spaced-apart legs 104 depending from a top web 106. Legs 104 are cut away as at 108 so that web 106 extends from cutaway edge 108 to its terminal end 110 a distance which is substantially the same as the distance between the outer surfaces of legs 96 and 98 on channel H. A rectangular plate member 112 is welded to terminal end 110 and projects downwardly the same distance as leg 104. Web 106 has opposite edge portions 114 and 116. Holes 118 are formed through plate member 112. Rectangular projections 120 and 122 are welded to the upper surface of web 106.
A plurality of shoes I are positionable on channel member H in spaced-apart relationship as shown in FIG. 11. Pins 126 are positioned through holes 118 in plate member 112 and holes 102 in channel member H for locking shoes I in a predetermined spaced-apart relationship on channel member H.
A plurality of elongated vertical guide means defined by vertical post members J having hollow rectangular cross-sectional configurations are positionable on shoes I. Post members J have open bottom ends which receive projections 120 or 122 on shoes I. With post members J positioned over projections 120, the outer surfaces of post members J are flush with opposite edges 114 and 116 on shoe 1. The outer surfaces of post members J are also flush with the outer surfaces of legs 96 and 98 on channel member H. Shoes I and post members J are spaced-apart any desirable distance depending upon the width of a wall unit which is to be constructed. Furthermore, post members J may be positioned at variable spacings along a horizontal channel member H when it is desired to construct a plurality of different width wall units in a single row.
Post members J are connected at their upper end portions by spacer beams 130. Spacer beams 130 have plate members as at 132 and 134 welded thereto and extending therefrom in parallel spaced-apart relationship. The inner surfaces of plate members 132 and 134 are spaced-apart a distance slightly greater than the width of post members J. Plate members 132-and 134 have threaded holes therethrough for threadably receiving wing bolts 136 which can be tightened to bear against the opposite outer surfaces of post members J for holding spacer beams thereto. The upper end portions of post members J are then spaced-apart the same distance as their lower end portions.
In accordance with a preferred arrangement, each post member J includes an outer post member 140 and an inner post member 142 telescopically received therein. The upper open end portion of outer post member 140 has a cap member 144 welded thereto. Cap member 144 includes an elongated cylindrical tube member 146. Inner post 142 is cylindrical and is reciprocatingly received through tube 146. The bottom end portion of inner post member 142 has a transverse slot therein receiving a bracket member 148. Coil springs are hooked onto the opposite end portions of bracket 148 and to hook members 152 on cap member 144. Springs 150 normally bias inner post 142 upwardly relative to cylindrical member 146. The combined length of inner and outer posts 140 and 142 is such that springs 150 normally bias inner post 142 upwardly into engagement with the underside of roof F on temporary shelter D.
In a preferred arrangement, manual operating means is provided for relieving the force of springs 150 and telescoping inner post 142 within outer post 140 so that post members J can be moved and properly positioned. In one arrangement, this operating means includes a lever member 156 pivotally connected as at 158 to a bracket member 160 welded to an outer surface of outer post 140. Lever member 156 is preferably located close enough to the bottom portion of post members J so that it can be reached by a person standing on base area 22 of slab B. An elongated link 162 is pivotally connected to lever 156 as at 164 and to a bracket 166 welded to the outer surface of inner post 142 as at 168. Lever member 156 is pivotal in a substantially vertical plane. Downward pivotal movement of lever 156 applies force through link 162 to inner post 142 for telescoping inner post 142 within outer post 140 against the biasing force of springs 150. Releasing lever 156 will allow inner post 142 to move outwardly relative to outer post 140 due to the biasing force of springs 150.
In a preferred arrangement, the upper end portion of inner post 142 has a substantially rectangular plate member 170 welded thereto. Plate member 170 has four Spaced-apart holes therein located at the corners of a rectangle or square. A rectangular wooden plate member 172 also has holes therethrough aligned with the holes in plate 170 for receiving bolts 174. The holes in plate member 172 are recessed as at 176 so that the heads of bolts 174 are recessed beneath the outer upper surface of plate member 172. Coil springs 180 are positioned around bolts 174 between plates 170 and 172 for normally biasing plate 172 away from plate 170. Nuts 182 are threaded onto the ends of bolts 174 on the bottom side of plate member 170. The holes in plate member 170 through which bolts 174 extend are somewhat larger in diameter than the diameter of bolts 174 so that plate member 172 may tilt in all directions for moving its upper surface out of a substantially horizontal plane into a plurality of inclined planes slightly inclined 'to the horizontal. This insures good bearing engagement with the under surface of roof F even if roof F is pitched. This provides a releasable friction engagement between plate member 172 and the under surface of roof F on temporary shelter D. Post members J are plumbed so as to extend vertically.
With channel H and post J so positioned, a bricklayer may position chalk line slides 186 on the'outer surfaces of adjacent spaced-apart posts J. Slide members 186 have notches 188 therein for receiving a string 190 which is then knotted or otherwise secured as at 192 after being stretched in tension between slide blocks 186. The tension in string 190 frictionally holds slide blocks 186 in their desired elevational position relative to post J. The exterior surfaces of post J may have spaced-apartindicia thereon for properly positioned slide blocks 186. A bricklayer then simply moves slide blocks 186 to the proper position on post members J so that guide string 190 extends horizontally and in the proper location for guiding the bricklayer in making each layer of brick substantially horizontaland at the proper height.
With the parts assembled as described, a mason may begin construction of a modular wall unit. A composite wall unit including concrete blocks and facing bricks will be described. The mason positions supports 202 rearwardly of channel H. Supports 202 have a thickness which is the same as the distance from the bottom edges of legs 96 and 98 on channel H to the uppersurface of web 94 thereof. Supports 202 may simply be wooden blocks or may be short lengths of channel section H. With supports 202 butted up against channel-H, the length of supports 202 is such that the concrete blocks will be aligned with their outer edges. The mason then begins laying concrete blocks on supports 202 with the forward end of the blocks resting on channel I-I. A first concrete block is indicated by numeral 204 in FIG. 16. The space remaining on channel H is adapted to receive facing bricks designated at 206. The mason continues to lay concrete blocks 204 between the inner facing surfaces of post members J until a rectangular vertical wall is constructed. Vertical post members J determine the desired width of the wall unit. U- shaped ties as at 210 are inserted at various positions in the joints of the concrete block wall for receiving additional ties which 'are positioned between various joints of facing bricks 206 for tying facing bricks 206 to the concrete block wall'in a known manner. Above the midpoint of te wall, the mason inserts brace attaching means in the form of bolts 212. Bolts 212 have threaded end portions 214 extending outwardly from the rear surface of the wall. Slide members 186 are simply moved vertically upward after laying each row of concrete blocks 204 so that string 190 will guide the mason. Once the wall of concrete blocks is completed, facing bricks 206 are laid on channel H beteween posts J in layer-by-layer fashion to form a facing brick wall. Concrete blocks 204 are hollow as indicated at 216 in FIG. 18. Hollow spaces 216 are vertically aligned throughout the length of the wall.
As soon as the concrete block wall is completed above brace attaching bolts 212, a diagonal brace member K is attached thereto as shown in FIG. 20. A bracket member L including a plate portion 220 having a hole therethrough is positioned on threaded end 214 of bolt 212. A nut 222 is then threaded onto-threaded end portion 214 for securing bracket L to rear surface 224 of the wall. Bracket 220 has spaced-apart outwardly projecting plates 226 with holes therethrough. Brace member K includes rod portions 228 and 230. The upper end portion of rod 228 is flattened and has a hole therethrough alignable with the horizontal holes in plates 226. A bolt 234 is positioned through the holes in plates 226 and the upper end of rod 228, and a nut is attached to the bolt for pivotally securing rod 228 to bracket L for pivotal movement in a substantially vertical plane.
A substantially U-shaped bracket member M in cludes spaced-apart upstanding plates 236 having aligned holes therein. The lower end portion of rod 230 is flattened and has a hole therethrough alignable with the holes in plates 236. A bolt 238 is receivable through the aligned holes for securing the lower end portion of rod 230 to bracket M. Suitable holes are drilled in slab B for receiving expanding anchors into which bolts 240 are threaded. Bolts 240 extend through suitable holes in base plate portion 244 of bracket M. Bolt 238 has a nut thereon. Either bolt 238 or bolts 240 are removable so that brace K is removably secured to slab B.
Brace K includes length adjustment means N for adjusting the length thereof. The lower end portion of rod 228 has right hand threads 250 formed thereon, while the upper end portion of rod 230 has left hand threads 252 formed thereon. A carrier member 254 defines a turnbuckle having threaded nuts 256 and 258 at opposite end portions thereof. Nut 256 has right hand threads while nut 258 has left hand threads. Nuts 256 and 258 are threaded onto end portions 250 and 252 of rods 228 and 230. Carrier member 254 is simply rotated for threading nuts 256 and 258 onto threaded portions 250 and 252 to move rods 228 and 230 toward or away from one another to adjust the overall length of brace K.
A standoff means in the form of a short rod 260 is also secured to brace K. A pair of spaced-apart plates 262 having holes therethrough are positioned on opposite sides of rod 228. Bolts 264 are positioned through the holes in plates 262. Nuts are applied to the bolts for securely clamping plates 262 together in spaced-apart relationship onto rod 228. The inner end portion of standoff rod 260 may have a hole therethrough alignable with one of bolts 264. This pivotally secures standoff rod 260 to brace K for limited pivotal movement in a substantially vertical plane. Inner end portion 268 of standoff rod 260 bears against rear surface 224 of the wall. When the wall is vertically raised, standoff rod 260 maintains brace K in its diagonal relationship so that the lower end portion of brace K does not fall below a horizontal plane extending through the bottom edge of the wall. When the wall is lowered into position, there is no danger of bending brace K and a workman does not have to hold it out from the wall while the wall is lowered onto the building foundation. Brace means K can be grabbed by workmen for manipulating the wall into the proper position as it is suspended from the cable of a hoisting crane.
FIG. 21 shows a front elevational view of a completed modular wall unit P. The wall includes top and bottom edges 270 and 272, and opposite side vertical edges 274. Finish bricks 206 define a front surface 276 on wall P.
Elongated reinforcing rods 280 having loops 282 on their upper end portions are inserted into openings 216 in the endmost vertical rows of concrete blocks 204. The spaces 216 in these rows of blocks are then completely filled with grout or concrete for securing rods 280 to wall P. In the arrangement shown, finish bricks 206 extend up higher than the endmost columns of concrete blocks 204. This provides ledges as at 288 on which beams may be positioned. Loops 282 may be re movably threaded onto rods 280. A chain or cable may be hooked onto loops 282 and the chain is connected with the cable of a hoisting crane C. A modular wall unit P may then be vertically raised from slab B for direct transportation over to the building foundation.
In constructing modular wall units, a first row of modular wall units is constructed on channel H of FIG. 6. After completion of that row, an additional channel H is laid extending substantially parallel to the first channel and spaced-apart therefrom around two feet. Vertical guide members J are then removed from the first row and positioned on the second channel. The vertical posts J are properly positioned and aligned as previously described. A second row of modular wall units is then constructed. This procedure continues until entire temporary shelter D is substantially filled with modular wall units. Brace means K secures the first row of wall units to slab B and prevents toppling thereof. Horizontal braces R as shown in FIG. 23 may be positioned between each succeeding row of wall units. Horizontal braces R may simply comprise opposite rod portions 302 and 304 having a turnbuckle 306 threaded thereon as described with respect to diagonal brace means K. Rods 302 and 304 may have plates 310 znd 312 thereon for bearing against the front surface of one wall and the rear surface of an adjacent wall.
It will be recognized that many different types of wall units may be constructed. Wall units which include only finished bricks may be constructed, and do not have to be a combination of blocks and bricks. Where walls are constructed in more than one layer, shoes I provide two projections 120 and 122 so that two channels H may be laid closely adjacent one another in parallel relationship. The first vertical layer of blocks or brick may then be assembled on one of channels H between posts J. Posts J may then be moved to the next projection on a shoe I for laying the next course of bricks.
It will be recognized that many different shapes of modular wall units may be formed in accordance with the present invention. For example, FIG. 24 shows channels H assembled in a substantially T-shaped configuration. Vertical posts J are positioned thereon in the manner previously described. Laying blocks on channels H of FIG. 24 will then form a substantially T- shaped wall unit S as shown in FIG. 25. Such a wall unit may also have rods attached thereto by inserting such rods into hollow spaces in the blocks and filling the spaces with concrete or grout. Columns J provide vertical guide means for all of the vertical edges of T-shaped modular wall unit S. FIG. 26 shows channels H positioned in a right-angular corner arrangement. Vertical columns .I are also positioned thereon in the manner previously described. Laying blocks on channels H of FIG. 26 between vertical guides J results in a vertical modular wall unit as shown at T in FIG. 27. Many other shapes of modular wall units, including substantially U- shaped units may be constructed. 1
When shelter D is filled with modular wall units, temporary shelter D is moved from first base area portion 84 over onto second base area 86 in the manner previously described. The modular wall units constructed on first base area portion 84 may then be lifted vertically upward by crane C and transferred laterally for lowering onto building foundation A. Naturally, the mortar in the wall units is allowed to set for at least three days before the wall units are moved. Meanwhile, construction of additional modular wall units may take place on second base area portion 86 within temporary shelter D.
It should be recognized that many modifications of the described procedure are possible. For example, it is possible to simply leave supporting legs 24 of temporary shelter D in position while transferring roof F thereof from such legs on each of first and second base area portions 84 and 86. In any event, it is desirable to completely remove roof F in order that the modular wall units can be lifted vertically from the construction area.
Each modular wall unit in each row constructed within temporary shelter D has brace attaching means 212 therein. Even though the braces are not attached to each succeeding row of wall units, such braces are usually attached before each wall unit is moved by crane C so that workmen can grasp diagonal braces K and manipulate each wall unit into proper position on building foundation A. It will be recognized that many other variations are possible. For example, spacer beams of FIG. 12 may have a plurality of spacedapart holes therein. Plates 132 and 134 may then be secured to a socket member slidably receiving spacer beams 130. Holes in the socket member would be alignable with the holes in spacer beams 130 so that plates 132 and 134 could be adjusted along spacer beams 130 for locating vertical posts J at any desirable spacing. It will also be recognized that the arrangement and procedure of the present invention may be used for constructing multi-story buildings. A large number of modular wall units may be constructed in the manner described and raised into position for each story of the building by crane C. Roof F of temporary shelter D is normally spaced a substantial distance above slab B. A movable scaffold is then positionable within temporary shelter D so that the workmen can construct walls having a substantial height, such as around 12 feet. However, it will be recognized that modular wall units of any height may be constructed within temporary shelter D.
It will be noted that the modular wall units are not tilted or otherwise moved until after the mortar has set. This takes around three days for high strength early setting mortar. It will also be noted that the modular wall units are not subjected to any bending stress which might break any joints. The units are lifted vertically from the base area and the joints are simply in shear due to the weight of the blocks and bricks. Channels H prevent adhesion of any wall units to slab B due to dropped mortar and mortar which might contact the slab from the vertical joints in the first layer of blocks or bricks. However, it will be recognized that other horizontal guide means, such as painted lines or plastic strips could be used for certain applications.
Although the invention has been shown and described with respect to a preferred embodiment, it is obvious that equivalent alterations and modifications will occur to others skilled in the art upon the reading and understanding of this specification. The present invention includes all such equivalent alterations and modifications and is limited only by the scope of the claims.
