Description

The invention relates to a flexible base for accommodation.

STATE OF THE ART

Flexible floor space for accommodations are known in the art. A disadvantage of these bases is that during assembly and disassembly tools such as hammer, nails, screwdrivers or the like for the assembly and disassembly of the individual elements are needed.

US 2009/188189 A1 describes a stabilization system for a platform having multiple sockets. In FIG. 5 The stabilization system consists of horizontally arranged rods and rods arranged at a sharp angle to the horizontal. At the ends of the rods holes are provided, which are attached to projections on the base (see FIGS. 3 and 4 ). The stabilizing rods are made of two telescopically arranged halves, which can be adjusted with a screw in a longitudinal slot to the correct length.

US 2012/291369 A1 shows a support structure for lifting a building surface above a solid surface with a stability brace to provide increased stability of the structure. The support structure includes a plurality of support pedestals disposed in spaced relationship on a solid surface. A plurality of struts are mounted on adjacent support sockets to connect the support sockets together. In FIG. 4
the struts are shown with an adjustable length. On the two strut halves gears are provided, which interlock. The two strut halves are fixed with thumbscrews (see section [0056]).

OBJECT OF THE INVENTION

Object of the present invention is therefore to provide an improved concept for a flexible floor space for accommodation, the base consists of individual modules, which have a predetermined size and can be constructed without tools to the desired base. Furthermore, the base can later be disassembled and transported into individual modules again without tools.

SCOPE OF THE INVENTION

This object is achieved by a clamping system for fixing a flexible base for a housing with the features of claim 1.

Embodiments of the present invention provide a clamping system for fixing a flexible base divided into a regular grid. The tensioning system comprises monoblocks, which can be arranged at crossing points of the grid and along the circumference. Between each two monoblocks one rod can be arranged along the grid. On the outside of the grid, the bars, which are arranged along the grid circumference, one

Clamping on. By means of the tensioning device, the monoblocks can be frictionally connected to one another at the two ends of the rod.

By the rods, the monoblocks are arranged in a uniform or at a regular distance from each other. This results in a grid, wherein the monoblocks are arranged at the intersections of the grid, while the bars are arranged along the grid lines. The modules for the construction of the accommodation have predetermined dimensions, which correspond to the dimensions of the grid. Thus, depending on the available or desired base area of the accommodation, accommodations with the corresponding floor space can be constructed or realized.

Along the outside of the grid, the rods have tensioning devices. With the Spanvorrichtungen the two monoblocks, which are arranged at the ends of the rod, connect non-positively with each other. Thus, a stable and solid framework for the accommodation is created without tools.

Furthermore, an accommodation is provided, which can be flexibly designed in its base area, wherein the base of the accommodation can be divided into a regular grid and at least partially wall elements can be arranged along the circumference of the grid. Wall elements may also include doors or windows.

FIG. 1 shows an accommodation 10, which is flexibly framed in their base. The accommodation 10 may also be referred to as a room or premises. Accommodation 10 may be inhabited or used by persons or animals. Furthermore, the accommodation 10 can be used for setting objects. The floor space or floor plan of the accommodation 10 may be divided into a regular grid, that is, the floor space is composed of regular geometric areas, such as rectangles. Particularly preferably, the base of the accommodation 10 consists of several juxtaposed squares. Since with squares the four side lengths are the same size, If the installation of square floor slabs in the grid, the orientation of the floor slabs can be changed. If patterns are present on the floorboards, certain structures can be created by the orientation of the floorboards. Furthermore, when constructing the accommodation with square floor panels, mistakes due to confusion of longitudinal and lateral sides can not occur. The squares have a side length between 0.4 m and 1.2 m. Preferably, the side length is between 0.7 m and 0.95 m. Particularly preferred about 0.85 m. This results in that the floor panels can be easily inserted by a person individually in the grid. Furthermore, a shorter side length provides a higher floor load of resting on the grid floor panels. There is thus a lower risk that the bottom plate is bent and damaged.

The bottom plates are inserted in the grid or between the grid. Thus, the base is divided into a regular grid. The grid has several crossing points. Monoblocks 12, for example lower monoblocks 12 _1, are arranged at the crossing points. Between the crossing points rods 14 (eg bottom rods 14 ₁ or center rods 14 ₃ ) are arranged. The rods 14 are arranged along the grid and along the shortest connecting path between two crossing points or two monoblocks 12. The monoblocks 12 are preferably made of plastics such as polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), carbon fiber composites, or other materials such as metals, such as iron or aluminum. The monoblocks can consist of a single material or of several different materials. The rods 14 may also be made of the aforementioned materials.

Along the circumference of the base of the accommodation 10, ie on the outside of the grid, wall elements 16 or straight walls or corner elements are arranged. The wall elements 16 can each be arranged centrally on the monoblock. The wall elements 16 are connected at the bottom with the bottom plates, the rods 14 or the lower Monoblöcken 12 ₁ or lie on these. there For example, the wall elements 16 may also comprise openings, for example for a door or for a window. The wall elements 16 may be multi-layered and, for example, an insulation and a weatherproof surface of metal, such as a sheet have. The wall elements 16 may also be transparent and, for example, at least partially made of glass or Plexiglas.

The wall elements 16 have a height between 1.8 m and 3 m, preferably the wall elements 16 have a height between 2 m and 2.2 m. The height of the wall elements 16 may be dependent on the preferred area of use of the accommodation. In warmer areas, a greater wall height may be preferred, while in cooler and wind-prone regions, a smaller wall height for the wall elements 16 is preferred.

In the in FIG. 1 shown embodiment, no bottom plates are inserted in the grid. As a result, the grid of monoblocks 12 and bars 14 is more visible through the openings in the walls.

At the top of the wall elements 16, a roof 18 is arranged. The roof 18 may be completely connected to the wall elements 16 on the underside of the truss by means of insulation boards, so that no air gap between the wall elements 16 and the roof 18 is present. The roof 18 may also have the shape of a truss (pent roof), so that on one side there is a gap opening (rear ventilation) between the roof 18 and the wall elements 16. As a result, in particular in warmer areas, an exchange between the air in the interior of the accommodation 10 with the outside air can be promoted.

FIG. 2 shows a detail of the clamping system for fixing or holding together an accommodation. The tensioning system has monoblocks (lower monoblocks 12 ₁ ), rods (bottom rods 14 ₁ ), and a tensioning device 20 at each of the two ends of the rod. The tensioning device 20 is described below in FIG FIG. 6 shown in more detail. The clamping system connects or clamps the monoblocks and the Rods. A bottom bar 14 ₁ is shown with a tensioning device 20 at each end of the bottom bar 14 ₁ . The bottom bar 14 ₁ is arranged between two lower monoblocks 12 ₁ . The tensioning device 20 is shown in a locked position. A lever 22 for opening and locking the tensioning device 20 abuts against the bottom bar 14 ₁ . The length of the lever 22 between a first axis of rotation and the opposite end of the lever 22 is smaller than the distance of the bottom bar 14 ₁ to the ground. The lever is thus shorter than the distance of the support of the bottom bar on the lower monoblock to the ground. As a result, the clamping device 20 can be opened and locked at any time for setting up and dismantling the accommodation. The tensioning device 20 can be adjusted in length to optimally adjust the compression in wall joints between the wall elements 16 and to accommodate manufacturing tolerances.

Upper monoblocks and roof bars also form a clamping system and can be connected or clamped in the same way as the lower Monoblöcken 12 ₁ and the bottom bars 14 ₁ . The connection between upper Monoblocke and roof poles are among other things in the FIGS. 17 to 19 shown in more detail. By the clamping systems, the accommodation can be constructed without tools only by means of the clamping devices 20.

The same applies analogously to upper monoblocks 12 ₂ and roof bars 14 ₂ which, inter alia, in US Pat FIGS. 15 to 19 to be discribed.

FIG. 3 shows the clamping system for fixing or holding together an accommodation 10 and receiving a roof truss. The accommodation is shown in the structure without wall elements and floor panels. The tensioning system includes monoblocks 12 and rods 14. The tensioning system ties or braces the monoblocks 12 and rods 14. The base of the shelter 10 is divided into a regular grid. The monoblocks 12 are arranged at crossing points of the grid and along the circumference of the grid. The grid comprises the crossing points and the circumference or the outside of the grid. The notion of grid refers to both the floor space of the accommodation 10 as well as on the upper part of the roof 18 of the accommodation 10. Between each two monoblocks 12 can each be arranged a rod 14 along the grid. On the outside of the grid, only the bottom bars 14 ₁ and the roof bars 14 ₂ , which are arranged along the grid periphery, clamping devices 20 at the two ends. Thus, the bottom bars 14 ₁ with the lower monoblocks 12 _{1 form} a lower fixed frame 13 and the roof bars 14 ₂ with the upper monoblocks 12 ₂ an upper fixed frame 15th

At the bottom of the property lower monoblocks 12 ₁ are arranged. The lower monoblocks 12 ₁ are arranged at the crossing points of the grid. The lower monoblocks 12 ₁ are also arranged along the circumference of the grid. The lower monoblocks 12 ₁ , together with the bottom bars 14 ₁ and center bars 14 _{3 form} a structure or a grid for receiving floor panels for the accommodation. The grid may be spaced from the underlying ground. The grid is preferably aligned horizontally or horizontally with respect to the underlying substrate. If the underlying surface is not level, the height of the monoblock can be adjusted by means of a leveling foot. A recess provided in the block can provide for the inclusion of the leveling foot. Furthermore, a horizontal plane for the grid can also be generated by differently high lower monoblocks 12 ₁ .

Along the circumference of the base surface perpendicular to the floor bars 14 ₁ standing wall rods 24 and corner bars 26 are added in the lower monoblocks 12 ₁ . Wall bars, which are arranged at one of the four corners 26 of the accommodation, can also be referred to as corner bars 26. The wall bars 24 or corner bars 26 serve, inter alia, for positioning or fixing (fixing) of the wall elements 16. The wall bars 24 preferably have a length which corresponds approximately to the height of the wall elements 16 of the accommodation.

At one, the lower monoblock 12 ₁ opposite end of the wall bar 24 and at the upper end of the wall rod 24 (corner bars 26), an upper monoblock 12 ₂ may be arranged. The upper monoblocks 12 ₂ together with the roof bars 14 ₂ a structure or grid for receiving a roof 18 or truss for the accommodation. Along the circumference of the base area, the roof bars 14 ₂ each connect two adjacent upper monoblocks 12 ₂ .

Both the bottom bars 14 ₁ and the roof bars 14 ₂ clamping devices 20 are arranged.

By the wall bars 24 and the corner bars 26, the lower monoblocks 12 ₁ and the upper monoblocks 12 ₂ are spaced apart. By the tensioning devices 20, the monoblocks 12 (lower monoblocks 12 ₁ and upper monoblocks 12 ₂ ) at the two ends of the rod 14 (bottom bars 14 ₁ and roof bars 14 ₂ ) are non-positively connected to each other.

FIG. 4 shows the area of an accommodation consisting of a grid. The grid is formed by bottom bars 14 ₁ , center bars 14 ₃ and lower monoblocks 12 ₁ . The bottom bars 14 ₁ run along the circumference of the grid. At the crossing points of the rods 14 and along the circumference of the grid, the lower monoblocks 12 ₁ are arranged.

FIG. 5 shows the wall elements 16 in cross-section, which are arranged along the circumference of the grid. The wall elements 16 are connected approximately in the middle between two lower monoblocks 12 ₁ with each other. The wall elements 16 preferably have approximately a width which corresponds to the distance between the midpoints between two with a bottom rod 14 ₁ connected to the lower blocks 12 Mono. ₁ The wall elements 16 are arranged approximately centrally on a lower monoblock 12 ₁ . Wall elements 16, which are arranged in a corner, can be referred to as corner elements. In corner elements two half as long wall elements, preferably at right angles to each other, arranged. The two each about half as wide wall elements are in an angle or L-profile each other.

The end faces of the bottom bars 14 ₁ are objected to by an end face of a form cutout of the lower monoblock 12 ₁ . By the spacing of the end faces of the bottom rods 14 ₁ to the end face of the mold cutout, the wall elements 16 are pressed together or pushed into each other when closing the clamping devices 20: thus creating a possible gas-tight connection between the wall elements sixteenth

FIG. 6 shows a connection between two wall elements 16. Preferably, the connection between two wall elements in a plurality of interlocking steps and not in a straight, perpendicular to the outside of the wall element extending line. This will create a gas-tight seal between the outside of the property and the inside of the property. Preferably, easily deformable and insulating materials, such as foam or rock wool, are arranged at least in a partial region of the surface in which the wall elements 16 adjoin one another. This easily deformable material (sealing tape) is then pressed together by the two adjacent wall elements 16. Thus, in each case two adjacent wall elements 16, which are arranged along the circumference of the grid, pressed against each other when closing the clamping devices 20 or moved into each other. By compressing the wall elements 16, a counterforce to the clamping force of the clamping devices 20 is generated and the bottom bars 14 ₁ locked.

FIG. 7 shows a clamping device 20 in side view. The tensioning device 20 comprises a ball 30, which is arranged on a threaded rod 32. The ball 30 is preferably disposed at one end of the threaded rod 32. Instead of the ball 30, a differently shaped end piece, preferably in the end region of the threaded rod, can be arranged. The tail may for example also be oval or cube-shaped. The end piece should be shaped so that it can be easily inserted into a counterpart. In the recessed in the counterpart state, the tail should be able to build a positive connection to the counterpart and thus no longer unintentionally from the Remove counterpart. The tail can be screwed or pressed onto the threaded rod. The threaded rod may have a thread which extends over the entire length of the threaded rod. The thread can also run only over a certain portion of the threaded rod.

Further, the clamping device 20 comprises a fastening 34 and a lever 22. The attachment 34 is connected to a rod, for example with a bottom bar 14 ₁ , non-positively. The attachment 34 may be screwed or welded, for example, to the bottom bar 14 ₁ . Perpendicular to the longitudinal axis of the threaded rod 32, two axes of rotation are arranged on the lever 22. The lever 22 is connected to the attachment 34 via a first axis of rotation 36, or the lever 22 is rotatably mounted on the attachment 34 about the first axis of rotation 36.

The threaded rod 32 is connected via a second axis of rotation 38, which runs parallel to the first axis of rotation 36, connected to the lever 22, or rotatably mounted on the lever 22 about the second axis of rotation. The second axis of rotation 38 comprises an internal thread into which the threaded rod 32 is screwed and thus connected to the second axis of rotation 38. By rotating the threaded rod 32 about the threaded axis, the distance of the ball 30 (or the tail) to the second axis of rotation 38 can be changed. Thus, the voltage which arises between the bottom bar and a lower mono block when closing the tensioning devices 20 in the locking position can be changed. The same also applies to the tension which arises between the roof bar and an upper monoblock when closing the tensioning devices 20 in the locking position. In the locked position of the tensioners 20, the second pivot 38 is closer to the bar (eg, to the bottom bar) than the first pivot 36. As a result, the tensioner 20 is held in the locked position and protected against accidental opening.

By moving the lever 22 about the first axis of rotation 36, the ball 30, or the end of the threaded rod 32, along the longitudinal axis of the rod (bottom bar or roof bar) is moved. The ball 30 of the tensioning device 20, which is arranged on the threaded rod 32, is thus displaceable or movable via the lever 22 along the longitudinal axis of the rod.

FIG. 8 shows a bottom bar 14 ₁ , each with a clamping device 20 at the two ends of the bottom bar 14 _first The bottom bar 14 ₁ can, as in the FIG. 8 shown to have an angle profile. The bottom bar may also have an L-shaped cross-section (L-profile). The angle profile consists of two, at a right angle to each other arranged, equal width flat bars, resulting in an isosceles angle profile. The L-profile can also consist of two arranged at a right angle, unequal width flat bars, resulting in a non-asingle angle profile. The bottom bar 14 ₁ may also have a T-profile (T-shaped cross section). In this case, the clamping device 20 is arranged on one side of the flat bar. On the opposite side of the flat bar, a second flat bar is arranged centrally in the longitudinal direction. A pole with a T-profile is in the FIG. 10 shown. The bottom bar 14 ₁ may also have a flat profile. Furthermore, the bottom bar 14 ₁ surveys or holes, which serve to position the walls have. Bottom rods 14 ₁ with the tensioning devices 20 are preferably arranged on the outside of the grid, along the grid circumference.

FIG. 9 shows a roof bar 14 ₂ , each with a clamping device 20 at the two ends of the roof rod 14 _second The roof bar 14 ₂ has a flat bar profile. The roof bar 14 ₂ may also have another profile, as above to FIG. 8 described.

Both bars, the floor poles and the roof bars, may have tensioning devices 20 in the end area. The tensioners 20 comprise a ball 30 as an end member on the threaded rod 32. The ball may protrude beyond the end of the rod in a locked position of the tensioner, or the ball can not protrude beyond the end of the rod in a locked position of the tensioner. The position of the ball, at the end of the rod in a locked state, may be dependent upon the shape of the monoblock to which the rod is to be non-positively connected.

FIG. 10 shows a center bar 14 ₃ with a T-profile. The central rod 14 ₃ is also arranged between two lower monoblocks 12 ₁ . The center rod 14 ₃ has for fixing or anchoring in the end region of the rod depending on a positioning cylinder or bolt 40. The positioning cylinder 40, on the one hand, predetermines the distance between two adjacent lower monoblocks. On the other hand, the positioning cylinder 40 positions and locks the center rod 14 ₃ in the lower monoblock. As a result, prefabricated elements, such as floor panels, can be precisely inserted into the resulting grid. Furthermore, in the built state of the accommodation is prevented that the lower monoblocks can move apart.

The wall bars may also have a T-profile. Wall bars, which are arranged at a corner of the accommodation, may have an angle profile. Furthermore, the center bars and the wall bars may have projections or holes which serve to position the floor panels or walls.

FIG. 11a shows a lower monoblock 12 ₁ in a three-dimensional view. On the lower monoblock 12 ₁ four, lying in a plane, mutually perpendicular shaped cutouts or recesses 42 _{1 are} formed, which each serve to receive one of the bottom bars. The cutouts 42 ₁ can be provided both for receiving floor rods with a clamping device 20 and for receiving a central rod with the positioning cylinder 40. For receiving the bottom bar, the lower monoblock may have a recess 44 ₁ in the mold cutout 42 ₁ . In the recess 44 ₁ , the threaded rod 32 can be received and positioned.

Further, in the mold cutout 42 ₁ , preferably at the end of the recess 44 ₁ , a bore 46 ₁ for receiving the ball or the end piece is arranged. The bore may preferably be slightly conical (becoming larger towards the bottom) to prevent the tail from jumping out. The bore 46 ₁ may be located at that end of the recess 44 ₁ , which is closer to the center or center of the lower monoblock 12 ₁ . If the end piece has a shape other than a ball, the bore may have a non-round shape or a complementary shape to the tail. In the bore 46 ₁ , the ball is preferably embedded in the construction of the accommodation with open clamping device. The threaded rod is inserted into the recess 44 ₁ . The bottom bar is placed on the mold cutout 42 ₁ .

In a center rod 14 ₃ , which comprises a position cylinder 40, the position cylinder is in a notch 48, which is formed perpendicular to the mold cutout 42 ₁ , positioned or inserted. The notch 48 is positioned, the central rod in the lower mono-block 12 ₁ and prevents, among other things, that the central rod is accidentally removed from the shaped cut-out 42 _1, and that two arranged at the opposite ends of the center rod lower monoblocks 12 ₁ move apart.

FIG. 11b shows a further three-dimensional view of the lower monobloc 12 ₁ . In the illustration, the lower surfaces of the recess 44 ₁ and the bore 46 _{1 are made} lighter. The bore 46 ₁ may be conical and widen down towards the lighter-colored surface. By such a cylindrical conical hole, a locking or anchoring of the ball at the end of the threaded rod in the bore 46 _{1 can be} reinforced.

FIG. 12a shows a plan view of the lower monoblock 12 ₁ with the four form cutouts 42 ₁ , depressions 44 ₁ , holes 46 ₁ and notches 48. The four shape cutouts 42 ₁ are cross-shaped, arranged in a plane. In the middle of the lower monoblock 12 ₁ , a profile hole 50 ₁ or a recess can be arranged perpendicular to the plane of the mold cutout 42 ₁ . In the profile hole 50 ₁ can be inserted vertically to the floor poles or center poles, wall bars or corner poles.

In addition to the center of the lower monoblock 12 ₁ or adjacent to the profile hole 50 ₁ , a recess 52 in the monobloc 12 _{1 is} arranged or incorporated. In the recess 52, a grid pin 54 is added. With the grid pin 54 wall bars or corner bars can be secured against unintentional removal from the profile hole. An embodiment of the grid pin 54 is in the FIG. 13a-c shown.

FIG. 12b shows a side elevation of the lower monobloc 12 ₁ . The lower monoblocks 12 ₁ may have different heights. Furthermore, the lower monoblock 12 ₁ may include an additional pad to increase or change the height of the lower monoblock 12 ₁ . For example, an additional surface can increase the distance between the floor of the accommodation and the ground. Due to the variable height, it is also possible, for example, to compensate for unevenness in the subsurface on which the accommodation is to be set up. The lower monobloc can also be connected via a thread with the additional pad. Due to the thread, the height of the lower monoblock can be finely adjusted by disassembling or twisting together the lower monobloc.

FIG. 13a shows a lower monobloc 12 ₁ with bottom bars 14 ₁ , center bars 14 ₃ and wall bar 24 in a plan view. The center rod 14 ₃ is positioned with a position cylinder 40 in the notch 48 of the mold cutout 42 ₁ . In addition to the center of the lower monoblock 12 ₁ , the grid bolt 54 is shown in the recess. By the grid pin 54, the wall rod 24 can be attached to the lower monoblock 12 ₁ .

FIG. 13b is an enlargement of the center of the monoblock 12 ₁ out FIG. 13a , In this case, the wall rod 24, which has a T-profile, in the center of the lower monoblock 12 ₁ in the profile hole 50 ₁ admitted. In the recess 52 next to the profiled hole 50 ₁ , the grid pin 54 is arranged. The grid pin 54 may, for example, by means of screws to a grid pin plate 56 with the lower monoblock 12 _{1 are} firmly connected. The grid pin 54 can be inserted into the T-profile of the wall bar 24 or pushed through the T-profile. The grid pin 54 can be slid into a borehole lying on the side opposite the recess 52. As a result, damage to the grid pin 54 is reduced by large forces which can act on the wall bar 24. By the grid pin 54, an inadvertent separation of the wall rod 24 or the corner bar of the lower monoblock 12 _{1 can be} prevented.

FIG. 13c shows a further view of the lower monoblock 12 ₁ with the grid pin 54 and the central rod 14 ₃ with the positioning cylinder 40th

FIG. 14 shows a 3-dimensional view of the lower monoblock 12 ₁ with two opposing bottom bars 14 ₁ , which are connected by the tensioning devices 20 with the lower monobloc 12 ₁ . In the same plane as the two bottom bars 14 ₁ , the center rod 14 _{3 is arranged} with the positioning cylinder 40 on the lower monoblock 12 ₁ . Perpendicular to the plane of the bottom bars 14 ₁ and center bar 14 ₃ , a wall bar 24 is anchored in the lower monoblock 12 ₁ .

FIG. 15a shows a three-dimensional view of an upper side of an upper monoblock 12 _second Upper monoblocks 12 ₂ are arranged at an end of the wall bars or corner bars opposite the lower monoblock. Together with roof bars 14 ₂ , the upper monoblocks 12 _{2 form} a structure for receiving the roof of the accommodation.

The upper monoblock 12 ₂ has three cutouts 42 ₂ for receiving the ball at the end of the threaded rod of the clamping device. The recordings exist from depressions 44 ₂ . At the ends or at the crossing points of the recesses 44 ₂ holes 46 _{2 are provided} for receiving the ball or the tail of the clamping device.

FIG. 15b shows a three-dimensional view of a bottom of the upper monoblock 12 _second On the underside profile perforations 50 _{2 are} formed, in which the wall bars and the corner bars are inserted.

FIG. 16a shows the floor plan of the upper monobloc 12 ₂ . The upper monoblock 12 ₂ has three (as in the FIG. 16a shown) or four cutouts 42 ₂ for receiving roof rails 14 ₂ on. Each cutout 42 ₂ has two recesses 44 ₂ , in which the threaded rods of the clamping devices 20 are inserted. At each mold cutout 42 ₂ a bore 46 _{2 is arranged} for receiving the ball of the clamping device. In the center of the upper monoblock is a profile hole 50 ₂ for receiving the wall bar or the corner bar. At the bottom of the upper monoblock a grid pin is also arranged. The grid bolt prevents the wall bars and the corner bars from being inadvertently removed from the upper monoblock 12 ₂ .

FIG. 16a shows the side elevation of the upper monoblock 12 ₂ . Like in the FIG. 16a it can be seen, the profiled hole 50 _{2 is formed} as a blind hole, that is not through the entire upper monoblock 12 ₂ through. This prevents the upper monoblock 12 ₂ from sliding down along the wall bar or corner bar.

FIG. 17 shows the upper monoblock 12 ₂ with two roof bars 14 _second The roof bars 14 ₂ have a flat bar profile and a clamping device 20. Both balls at the end of the threaded rods of the clamping device 20 can be arranged in the upper monoblock 12 ₂ one above the other in the same bore of the upper monoblock 12 ₂ . In this case, one of the roof rods 14 ₂ rest on the upper monoblock 12. ₂ The other roof bar 14 ₂ may be spaced from the upper monoblock 12 ₂ .

The roof bars 14 ₂ are, as already mentioned above in the floor bars, spaced from the end face of the mold cutout. By the distance of the end faces of the roof bar 14 ₂ to the end face of the mold cutout the wall elements are pressed together or pushed into each other when closing the clamping device 20, and there is a gas-tight connection between the wall elements.

FIG. 18 shows a side view of the upper monobloc 12 ₂ with two roof bars 14 ₂ , the balls 30 of the clamping device in the same bore 46 _{2 of} the upper monoblock 12 ₂ are arranged one above the other. This double use of a hole 46 ₂ or a hole happens in the corners. At the bottom of the upper monoblock 12 _{2 of} the grid pin 54 is arranged for locking the upper monobloc 12 ₂ with the wall bar or the corner bar.

FIG. 19 shows a three-dimensional view of an upper monoblock 12 _second Opposite one another two roof rails 14 ₂ are arranged. The roof bars 14 ₂ are frictionally connected by the tensioning devices 20 with the upper monoblock 12 ₂ . At right angles to the plane of the roof bar 14 ₂ , the wall bar 24 is arranged on the upper monoblock 12 ₂ . Approach is in the FIG. 19 also shown a roof construction. The upper monoblock 12 ₂ thus takes over in addition to the positioning of the wall elements 16 (walls) and the clamping function and the inclusion of the trusses of the roof 18th

The FIGS. 20 and 21 show a three-dimensional view of a variant of the lower monoblock 12 ₅ with a bottom bar 14 ₁ , in which the clamping device 20 instead of the ball 30 as a tail a circular disc 60 at the end of the threaded rod 32 has. The tensioning device 20 is arranged on one side only on the bottom bar 14 ₁ . How out FIG. 21 can be seen, the monoblock 12 ₅ exclusively notches 48, in which both the plate-shaped end 61 of the center rod 14 ₃ and the circular disc 60 of the bottom bar 14 ₁ fits. It will be understood by those skilled in the art that instead of a circular disc 60, a square plate may also be used, similar to the plate-shaped corner piece 61 of the central rod 14 _3rd The lever 22 is functionally similar to the execution of the FIG. 7 but formed as a U-profile 62 with a flat handle 63.

In FIG. 22 Furthermore, a Einsteckbügel 64 can be seen, which may be provided instead of the grid pin 54. For this purpose, two parallel bores (not recognizable) are now provided in the middle rod 14 ₃ , through which the insertion bracket 64 is inserted and held in corresponding blind holes in the monoblock 12 ₅ . Furthermore, a wall rod 24 is still ersichtllich, which is inserted into the monobloc 12 ₅ .
