Abstract
The masonry block wall system comprises masonry blocks fastened together with interconnecting threaded steel fasteners. Four fasteners on each block connect with a pair of identical blocks immediately above and a pair of identical blocks immediately below the block. The resulting masonry wall is structurally sound and allows large vertical chases or conduits for electrical, plumbing and the like. Unlike conventional masonry, the construction of the present masonry wall does not require specialized knowledge and skill of a mason and is relatively easy to build. As well, the masonry wall system is not dependant upon weather during construction and can be deconstructed without demolition.
Description
MASONRY WALL SYSTEM
FIELD OF THE INVENTION
The present invention relates to a masonry wall system in which masonry blocks are interconnected using mechanical fasteners.
BACKGROUND
Masonry block walls are presently constructed using concrete blocks stacked on top of each other. The blocks are bonded together using cement mortar (both in the horizontal and vertical joints). A wire-reinforcing ladder is iiistalled in the periodic horizontal joints. Construction of a masonry block wall requires a skilled mason. The construction of a masonry block wall requires a controlled environment while the cement mortar cures.
In conventional masonry construction, the designer (the design engineer) has few means of knowing that the block wall is built in accordance with the designers specifications, for example: the mortar being oorrectiy installed and having adequate strength, the concrete filled cores being completely filled and the reinforcing steel being placed correctly or being installed at all. The designer has to rely heavily on the integrity of the mason and the mason's workers that the masonry wall was properly built.
Traditional masonry units have vertical chases or conduits for installing plumbing lines, electrical conduits and other building services, but the vertical holes are often small and are commonly filled with cement grout or concrete and thus very often not contirtuous from top to bottom.
United States Patents 1,499,483 (Simms), 5,685,119 (Zschoppe), 5,899,040 (Cerrato) and 6,244,009 (Cerrato) disclose various examples of a wall construction using masonry type blocks. In each instance, the block has an irregular shape for interlocking connection with adjacent blocks. The blocks thus require complex molds for manufacturing. Rods are used in some instances for interconnecting adjacent blocks, however the rods are intended to span plural rows resulting is a wall which permits some relative movement between the biocks.
This relative movement is typically undesirable in a large static structure.
US 5,787,675 (Futagi) discloses a log wall construc'tion in which mechanical fasteners are used for interconnecting the logs of the wall. The fasteners include a washer formed integrally thereon which has cleats for bearing into the logs being fastened. The configuration of the cleats would interfere with the use of the fasteners on a masonry wall construction.
SUMMARY OF THE INVENTION
According to one aspect of the invention there is provided a masonry block in combination with a plurality of masonry fasteners, for use in a masonry wall structure having a pair of opposing surfaces;
the masonry block comprising a rectangular body with upright flat sides for forming the opposing surfaces of the masonry wall structure, the upright flat sides spanning in a longitudinal direction of the block, and a piurality of fastener apertures formed in the rectangular body to extend from a top side to a bottom side of the block and receiving respective ones of the plurality of masonry fasteners therein;
at least some of the fastener apertures receiving the masonry fasteners therein being spaced from one another in a lateral direction transverse to the longitudinal direction such that the lateral direction extends between the opposing flat sides which form the opposing surfaces of the masonry wall structure; and each masonry fastener comprising:
an elongate body corresponding in length to a height between the top and bottom sides of the block;
an externally threaded portion near a bottom end of the elongate body;
a nut portion adjacent a top end of the elongate body; and an intemally threaded bore formed in the nut portion at the top end of the elongate body which is suitably sized to operatively receive the externally threaded portion of an additional masonry fastener of identicai configuration, According to another aspect of the present invention there is provided a masonry wall system comprising rows of masonry blocks supported one above the other to form a masonry wall structure having a pair of opposing surfaces in whioh each masonry block is connected to at least one masonry block immediately therebelow by a plurality of masonry fasteners:

As described herein, the masonry wall system resufts in a mvrtarless block wall comprising concrete block units that are connected together with steel connectors. The steel connectors main purposes are to provide tensile strength to the wall to resist bending stresses (created from lateral loads such as wind and eccentric verticai wall loading). The block walls are placed on top of the lower course of masonry units (the vertical joints are stagger from the block course below -running bond). The steel connectors also serve a secondary purpose of providing a guide for the masonry block units being placed.
The masonry wall system of the present invention (or mortariess biock wall) possesses numerous benefits and advantages over the traditional masonry wall construction. Most significantly, the mortarless block wall can be built without the specialized skills and knowledge of a niason. As well, the mortarless block wall can be constructed in any weather conditions without affecting its structural integrity (unlike traditionai masonry wall construction that is effected by weather condition that in tum affects its structural integrity such as frozen mortar in cold weather, baked mortar in hot weather or dried mortar in windy weather). As well, as the mortariess block wall is constructed it has immediate structural strength (unlike conventionai masonry construction, which only has strength after the cement mortar has cured).
Having instantaneous strength is beneficial when the walls an? exposed to construction in windy condikions. Another benefit to the mortarless block wall is that the construction can be de-constructed by simply reversing the construction process.
The masonry block units and the nietai connectors can be re-used over and over again.
The mortarless block wall is lighter than traditional block walls and the walls have greater resistance to wind loads (both posi#ive pressure loads and negative suction loads). As well, the mortarless block wall has greater horizontal shear resistance than traditional block walls (which relies on the strength of the cement mortar).
The mortarless block wall requires the use of the masonry fasteners of the present invention to work property and so there is no incentive or means for the 5 wall builder to skimp on material or do shoddy workmanship.
Another advantage of the mortarless masonry block is that it has large continuous vertical holes in the center. These holes can be used for installing plumbing lines, etectrical conduits and other building services and wori't get plugged with mortar or concrete when installed due to the use of the masonry fasteners 10 according to the present invention.
The masonry block wall's vertical holes must line up vertically and in fact are guide for the proper placement of the block units.
One embodiment of the invention will now be described in conjunction with the accompanying drawings in which:

DETAIl.ED DESCRIPTION
Referring to the accompanying figures there is illustrated a masonry wall system generally indicated by reference numeral 10. The system 10 includes a plurality of masonry blocks 12 which are mechanically coupled to one another using masonry fasteners 14 as described herein.
Each masonry block 12 comprises a rectangular body of pre-cast concrete which is elongate in a longitudinal direction between opposing ends 16 of the body. The height and lateral width transverse to the longiitudinal direction are approximately equal to one another, having dimensions each of approximately millimetres while the length is approximately double. The blocks each include flat side walls 18 which form the surfaces of the wall structure being formed when the blocks are stacked on top of one another. Each block also includes aflat top side 19 and a flat bottom side 20 which permits stacking of the blocks on top of the other.
Each block includes a centrally located round conduit 24 having a diameter which is more than half of the width of the block which extends through the block from the top side to the bottom side thereof. The conduit is centered both laterally and longitudinally. Each end 16 of the block also includes a partial conduit 26 which comprises a channel open to the exterior end of the block and which is shaped to correspond to half of the cross sectional shape of the central round conduit 24.
Accordingly when two blocks are abutted in an end to end configuration two partial canduits 26 are opened to one another and form an assembled conduit which is identical in cross section to the central round conduit 24.
Two webs 28 are integrally formed in each block to span between the opposing sides 18 of the block to divide the central conduit 24 from eacti of the partial conduits 26 at opposing ends of the block. Each web 28 is located spaced from a respective end of the block by approximately one quarter of a length of the block in the longitudinal direction so that the resutting space between the webs 28 locating the central conduit is approximately equal to double the space between each web 28 and the respective end of the block locating the partial conduits.
Fastener apertures 30 are also formed in the block for slidably receiving the masonry fasteners 14 therethrough. Each of the fastener apertures 30 comprises a through bore extending from the top side 19 to the bottom side 20 of the block. A

DETAIl.ED DESCRIPTION
Referring to the accompanying figures there is illustrated a masonry wall system generally indicated by reference numeral 10. The system 10 includes a plurality of masonry blocks 12 which are mechanically coupled to one another using masonry fasteners 14 as described herein.
Each masonry block 12 comprises a rectangular body of pre-cast concrete which is elongate in a longitudinal direction between opposing ends 16 of the body. The height and lateral width transverse to the longiitudinal direction are approximately equal to one another, having dimensions each of approximately millimetres while the length is approximately double. The blocks each include flat side walls 18 which form the surfaces of the wall structure being formed when the blocks are stacked on top of one another. Each block also includes aflat top side 19 and a flat bottom side 20 which permits stacking of the blocks on top of the other.
Each block includes a centrally located round conduit 24 having a diameter which is more than half of the width of the block which extends through the block from the top side to the bottom side thereof. The conduit is centered both laterally and longitudinally. Each end 16 of the block also includes a partial conduit 26 which comprises a channel open to the exterior end of the block and which is shaped to correspond to half of the cross sectional shape of the central round conduit 24.
Accordingly when two blocks are abutted in an end to end configuration two partial canduits 26 are opened to one another and form an assembled conduit which is identical in cross section to the central round conduit 24.
Two webs 28 are integrally formed in each block to span between the opposing sides 18 of the block to divide the central conduit 24 from eacti of the partial conduits 26 at opposing ends of the block. Each web 28 is located spaced from a respective end of the block by approximately one quarter of a length of the block in the longitudinal direction so that the resutting space between the webs 28 locating the central conduit is approximately equal to double the space between each web 28 and the respective end of the block locating the partial conduits.
Fastener apertures 30 are also formed in the block for slidably receiving the masonry fasteners 14 therethrough. Each of the fastener apertures 30 comprises a through bore extending from the top side 19 to the bottom side 20 of the block. A
counter bore 32 is formed at the bottom side of each fastener aperture 30 which is slightly larger in diameter than the through bore of the fastener apertures.
The counter bore 32 extends axially less then half a depth of the masonry block 12.
Two fastener apertures 30 are provided at laterally spaced positions within each web 28 so that a set of four fastener apertures 30 are pnavided in each block in a rectangular configuration spaced both laterally and longitudinally relative to one another. By locating the apertures 30 spaced apart within each oi' the webs, the fastener apertures are similarly located so as to be spaced from a respective end of the block by approximately one quarter of a total length of the block in the longitudinal direction. Accordingly, the fastener apertures of the two webs are spaced apart from one another approximately twice the distance of the spacing of each fastener aperture from the respective end of the block.
Each masonry fastener 14 according to the present invention includes an integral body which corresponds approxlmately in length to a height of the block between the top and bottom sides thereof so that the fastener spans the height of the block and has some additional length for overlapping in a lengthwise direction the fastener of an adjacent row of blocks stacked thereabove when the fasteners are engaged with one another in a mating connection.
The fastener body includes an elongate shaft having an external threaded portion 34 at the bottom end. Diameter of the shaft and threaded portion 34 is approximately equal to the diameter of the through bore of the fastener apertures 30 for slidably receiving the fasteners within the apertures in use. The external threaded potion 34 comprises a machine screw fcar threaded securement to a suitable mating nut.
A nut portion 36 is provided at the top end of the fastener body which has a hexagonal cross section similar to conventional nuts for example for gripping with a wrench or socket tool and the fike. Length and diameter of the nut portlon 36 is approximately equal to or less than the respective length and diameter of the counter bore 32 so that the nut portion is receive within the counter bore when stacking blocks. The through bore and counter bore of the fastener apertures 30 are close enough in dimensions to the shaft defining the threaded portion 34 and the nut portion 36 of the masonry fasteners to provide a snug fit of the fasteners within the apertures to maintain proper alignment of the masonry blocks 12 relative to adjacent blocks.
The nut portion 36 includes an intemally threaded bore 38 at the top end which is suitably sized for mating engagement with the threaded portion 34 of another masonry fastener 14 of identical configuration. A washer 40 is located between the nut portion 26 and the shaft defining the threaded portion 34 for abutment against the top side of the masonry block 12 which receives the threaded portion 34 through one of the fastener apertures 30 therein. An engaging surface of the washer 40, which faces the threaded portion and which lies perpendicular to a longitudinal direction of the fastener, is flat for abutment with the masonry block 12.
Using the masonry wall system 10, a wall structure can be erected in which masonry blocks 12 are mechanically joined by masonry fasteners 14 as described herein. A base of concrete 42 is first formed where the wall is to be erected.
Fasteners 14 are embedded in the concrete when the concrete is still wet. The fasteners 14 are embedded such that the threaded portion 34 is embedded Into the concrete but the nut portion extends above the top surface of thie concrete. A
retention nut 44 can be secured to the bottom end of the threaded portion 34 prior to insertion of the fasteners into the wet concrete, The fasteners are suitably spaced from one another for alignment with the fastener apertures 30 of the first row of blocks to be formed.
The first row is formed by placing the blocks in an end to end configuration in a longitudinal direction of the blocks so that the partial conduits 26 of each block join with those of adjacent blocks to form complete conduits. The counter bores 32 are inserted overtop of the nut portions 42 which project up and outwardly from the concrete base once the base has cured. The blocks in the first row are secured in place by inserting the threaded portion 34 of a masonry fastener 14 into each of the fastener apertures 30 so that the bottom end is matingly engaged with the internally threaded bore 38 of the fasteners embedded in the concrete therebelow.
As the fasteners 14 reGeived through the blocks are threaded into the fasteners therebelow and tightened in place, the washer 40 and nut portion 36 thereabove clamp down on to the top side of the blocks. The close fit of the fasteners with respect to the through bore and oounter bore of the fastener apertures 30 assists in proper alignment of the masonry blocks.
Each subsequent row is place above the previous row by sequentially placing the masonry blocks in an end to end configuration in a longitudinal din,ction of the blocks along the previous row. The frst block is positioned so as to be offset in a longltudinal direction by half a block length relative to the previous row to form a staggered pattem. Due to the spacing of the conduits and fastener apertures, each pair of joined partial conduits 26 aligns with a central round conduit 24 of the rows 5 thereabove and therebelow.
Similarly the fastener apertures of each masonry block align with fastener apertures of two separate blocks in the rows immediately above and below.
As each subsequent row is formed, the masonry fasteners inserted therein are threadably engaged with the fasteners of the pervious row and tightened untll the nut 10 porhon thereof clamps down onto the top surface of the respective blocks.
The location of the masonry fasteners permits the first row of blocks to be anchored to the concrete base forming a supporting surface of the wall while eacti block in the subsequent rows is anchored to two adjacent blocks in the row above and two adjacent blocks in the row below. Accordingly, the finished wall structure includes 15 biocks which are sufficiently interconnected by mechanical fasteners to be self supporting without any grout materiai being required to join the blocks.
As described herein, the masonry wall system 10 (or mortarless block wall) consists of a masonry block 12 and a masonry fastener 14 comprising a steel connector. Construction of the block wall starts with first installing a connector to a concrete base (concrete wall, slab, footing, etc) with a base steel connector.
This base steel connector is either installed in wet concrete (not hardened yet) or installed in cured conorete (hardened concrete). If the base steel connector is installed in wet concrete, a nut is placed at the and of the steel connector to increase the tensile anchorage strength of the steel connector. If the steel connector is installed in cured concrete, then an oversized hole is drilled in the concrete and the connector is installed with an epoxy grout in the hole with the connector. In either Installation of the base connector, care is required to place the connector in the correct location.
Once the base connector is installed, the standard masonry blocks 12 are installed over the base connector. The standard steel connectors are then inserted in the top of the masonry block (or unit) and after the wall has been straightened and plumbed, the steel connectors are tightened snug. After the first masonry course is placed the second course is installed and again the steel connectors are inserted in the top of the masonry unit. Again after the second course of masonry units have been straightened and plumbed, the steel wnne+ctors are tightened snug. The process is continued until the full height of the wall is completed.
A form can be placed at the ends of the wall, or at an opening, etc and the rough openings or ends of the wall can be finished with concrete. To achieve a greater fire resistance in the mortarless biock wall, the vertical and horizontal joints in the wall can be caulked with a fire retardant caulking. The caulking serves another purpose, to straighten out vertical block unevenness.
Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without department from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
Fasteners 14 are embedded in the concrete when the concrete is still wet. The fasteners 14 are embedded such that the threaded portion 34 is embedded Into the concrete but the nut portion extends above the top surface of thie concrete. A
retention nut 44 can be secured to the bottom end of the threaded portion 34 prior to insertion of the fasteners into the wet concrete, The fasteners are suitably spaced from one another for alignment with the fastener apertures 30 of the first row of blocks to be formed.
The first row is formed by placing the blocks in an end to end configuration in a longitudinal direction of the blocks so that the partial conduits 26 of each block join with those of adjacent blocks to form complete conduits. The counter bores 32 are inserted overtop of the nut portions 42 which project up and outwardly from the concrete base once the base has cured. The blocks in the first row are secured in place by inserting the threaded portion 34 of a masonry fastener 14 into each of the fastener apertures 30 so that the bottom end is matingly engaged with the internally threaded bore 38 of the fasteners embedded in the concrete therebelow.
As the fasteners 14 reGeived through the blocks are threaded into the fasteners therebelow and tightened in place, the washer 40 and nut portion 36 thereabove clamp down on to the top side of the blocks. The close fit of the fasteners with respect to the through bore and oounter bore of the fastener apertures 30 assists in proper alignment of the masonry blocks.
Each subsequent row is place above the previous row by sequentially placing the masonry blocks in an end to end configuration in a longitudinal din,ction of the blocks along the previous row. The frst block is positioned so as to be offset in a longltudinal direction by half a block length relative to the previous row to form a staggered pattem. Due to the spacing of the conduits and fastener apertures, each pair of joined partial conduits 26 aligns with a central round conduit 24 of the rows 5 thereabove and therebelow.
Similarly the fastener apertures of each masonry block align with fastener apertures of two separate blocks in the rows immediately above and below.
As each subsequent row is formed, the masonry fasteners inserted therein are threadably engaged with the fasteners of the pervious row and tightened untll the nut 10 porhon thereof clamps down onto the top surface of the respective blocks.
The location of the masonry fasteners permits the first row of blocks to be anchored to the concrete base forming a supporting surface of the wall while eacti block in the subsequent rows is anchored to two adjacent blocks in the row above and two adjacent blocks in the row below. Accordingly, the finished wall structure includes 15 biocks which are sufficiently interconnected by mechanical fasteners to be self supporting without any grout materiai being required to join the blocks.
As described herein, the masonry wall system 10 (or mortarless block wall) consists of a masonry block 12 and a masonry fastener 14 comprising a steel connector. Construction of the block wall starts with first installing a connector to a concrete base (concrete wall, slab, footing, etc) with a base steel connector.
This base steel connector is either installed in wet concrete (not hardened yet) or installed in cured conorete (hardened concrete). If the base steel connector is installed in wet concrete, a nut is placed at the and of the steel connector to increase the tensile anchorage strength of the steel connector. If the steel connector is installed in cured concrete, then an oversized hole is drilled in the concrete and the connector is installed with an epoxy grout in the hole with the connector. In either Installation of the base connector, care is required to place the connector in the correct location.
Once the base connector is installed, the standard masonry blocks 12 are installed over the base connector. The standard steel connectors are then inserted in the top of the masonry block (or unit) and after the wall has been straightened and plumbed, the steel connectors are tightened snug. After the first masonry course is placed the second course is installed and again the steel connectors are inserted in the top of the masonry unit. Again after the second course of masonry units have been straightened and plumbed, the steel wnne+ctors are tightened snug. The process is continued until the full height of the wall is completed.
A form can be placed at the ends of the wall, or at an opening, etc and the rough openings or ends of the wall can be finished with concrete. To achieve a greater fire resistance in the mortarless biock wall, the vertical and horizontal joints in the wall can be caulked with a fire retardant caulking. The caulking serves another purpose, to straighten out vertical block unevenness.
Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without department from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
