Cl. 52-279 1 Claim ABSTRACT OF THE DISCLOSURE Beams have block interlock faces on their ends for interlocking support in a corresponding wall, and have a counter groove in their upper surfaces for receiving a horizontal ledge portion of ledge blocks which are at a corresponding level in the opposite layer of said wall.
This is a divisional application of Ser. No. 784,282 filed Dec. 6, 1968, now abandoned, which is a continuation of Ser. No. 653,170 filed July 13, 1967, now abandoned.
This invention relates to a building system using interlocking blocks, bricks, tiles, panels and the like, requiring no mortar, cement or other binder materials in the construction of Walls, roofs, decks, road beds, side walks, pillars, silos, enclosures, swimming pools, ducts, linings and the like.
The basic unit in a system of this type has a rectangular face area of a suitable unit height and a unit length and has alternate dove-tailed grooves and ridges on its internal face for slidably interlocking with corresponding ridges and grooves respectively, of similar blocks laid in the opposite layer of a double layer wall or slab during its erection, the blocks in one layer being laid in overlapping relation with respect to those in the other layer while lining up the internal faces of the opposite layers to form continuous grooves and ridges in the adjacent blocks, so as to slidably interlock with the ridges and grooves of the overlapping blocks of the opposite layer as it is slid into place to rigidly interlock said adjacent blocks in the direction normal thereto.
The object of this invention is to provide a system of interlocking block forms that require no application of any binding materials to hold the blocks together as they are laid in overlapping interlocked relation in the construction of straight or curved wall structures including floors, roofing and beam structures, and having corners and cross walls at any desired angles as well as openings for doors, windows and the like.
A further object is to provide a basic form of block or panel having alternate dovetail grooves and ridges in at least one face, that may be used in building a multilayer wall, floor, road bed or roof slab, etc. in which the grooves and ridges of the blocks or panels in one layer are interlocked with the ridges and grooves of overlapping adjacent blocks in the adjacent layer, so that no cementing binder material is necessary to hold the blocks in place as they are laid successively in their overlapping relations in the several layers of the wall or slab.
A further object is to make the blocks and panels of formed sheet material or extrusions having axially extending alternate dovetail shaped ridges and grooves on one face to provide the interlock between adjacent blocks or panels in one layer and their overlapping panels in an adjacent layer.
A further object is to make these sheets or extrusions of various multiple unit lengths and/ or multi-unit heights,
so as to enable the construction of extensive walls with fewer blocks or panels.
A further object is to make these blocks or panels of formed sheet material having limited flexibility in the horizontal direction, whereby curved or circular walls, cylinders or tubes may be built with substantially sealed joints and without using any piercing connections between the blocks or panels, or any welded joints, to hold the walls together.
A further object is to provide interlocking blocks for interior and exterior rectangular corners as well as for T and wall corners.
A further object is to provide blocks for forming interlocked frames in openings in the wall for doors, windows. etc.
A further object is provide matching semi-circular grooves in the side edges of these blocks, forming a circular bore in the vertical joints between blocks for the reception of sealing materials, and circular sectioned sealing strips adapted for insertion in these bores and sealing strips for the horizontal joints between blocks in each layer of the wall.
A further object is to provide blocks of this type having integral ledge portions extending outwardly from their outer faces or inwardly from their internal faces as may be desired.
A further object is to provide blocks for forming an eave corner having a suitable angle with respect to the vertical wall.
A further object is to provide arcuately formed blocks for the inner and outer layers in circular walls having any desired radius of curvature adapted for constructing silos, circular ducts, pipes, etc.
A further object is to provide the grooves and ridges on both faces of each block as to enable the construction of a road bed with with vertically interlocked blocks or a multi-layer wall having more than two layers.

FIG. X shows a cap unit having an interlocking portion of half the height of this basic unit for finishing the top of a wall or other slab,
FIG. XI shows this basic unit provided with tongue and groove joining configurations in the top and bottom to provide some sealing as well as more perfect alignment of the external faces of the blocks, and semi-circular grooves in the side ends of the block to form continuous vertical bores in each wall layer for receiving sealing material in the vertical joints,
FIG. XII is a plan view of the top of a wall portion showing a joint forming a vertical bore with a rod of flexibly resilient sealing material inserted therein having radially extending fins for resilient contact with the sides of the bore, and a flat sealing strip on top of the row of blocks in one layer of the wall ready for laying the next row of blocks,
FIG. XIII shows a block unit with another arrangement of the vertical grooves, locating them nearer to the external face of the block, and no horizontal tongue and groove provisions in the top and bottom of the block,

Referring now to the drawings, FIG. I shows the basic unit block 2 having a rectangular face area of any suitable unit dimensions U and X and a thickness substantially /3 of said unit length dimension U of the rectangular face, the depth of the groove 4 or height of the ridge portions 6 being about half this thickness or U/6. The thickness of a wall would be /2 of this unit length dimension. Obviously, these unit length and height dimensions U and X and the relations of the other dimension may be varied to suit material weight and strength requirements of any particular system.
FIG. II shows a fractional block 8 having the same configuration and dimensions except its height which is substantially /2 of a basic unit block 2. This block may be used in the first course in one layer at the base of the wall so as to start the vertical overlaps of the courses in the two layers as they are alternately built up by adding the successive courses.
FIG. III shows a multi-unit block 10 having a length of two units with a complete ridge 12 in the middle of the internal face, flanked by two grooves 4, leaving two ridge portions 6 at the sides of the internal face. Other multiunit blocks may be made having unit length increments beyond this two unit length to any length desired, and/ or unit height increments over the unit height of the basic unit block to any height desired. For small thicknesses and/or light materials, it may be preferable to use larger multi-unit blocks within suitable weight limitations for easy handling.
FIG. IV shows a fractional unit block having half the length of the basic unit block with only portions 16 and 6 of a groove and a ridge respectively, which block may be used to fill in a horizontal overlap at the end of a course of blocks to square off the end of a wall.
FIG. V shows one form of corner or cross block 18 comprising a basic unit block having a half length block extending from one side of the external face of the unit block to provide the first block in the inner layer of the wall on each side of the corner or corners.
FIG. VI is an alternate form of corner block 20 having a square corner post whose square cross-section has a dimension of /2 of a unit, and a half length block extending therefrom on each side of the corner to provide the first block in the outer layer of each wall extending from the corner.
FIG. VII shows a multi-length unit block 22 having a length of 1 /2 units.
FIGS. VIII and IX show unit blocks 24 and 32 with a solid rectangular pillar portion block 26 and a like 30 hollow block 34 respectively extending from the external faces of said unit blocks. The solid block 26 may be provided with a nesting pocket 28 in one end of said block and a correspondingprojection 30 at its other end.
FIG. X shows a half unit height cap block 36 having a cap 38 extending from the top of said half unit height block portion to fill out the vertical overlap of the top course in one layer and simultaneously provide a cap over the entire thickness of the wall.
FIG. XI shows a unit block 52 provided with semi- 40 circular grooves 54 in the outer sides of its ridge portions 6. The circular bores formed by these grooves in the vertical joints between blocks may be filled with sealing means, such as 70. Tongue and groove means 56 and 58 may be made at top and bottom of the block to provide a weather seal in the horizontal joints as well as to improve alignment of the faces of the blocks.
FIG. XII is an enlarged detail plan view of a portion of a wall, showing portions of three interlocked blocks 2, two of which, in the one layer, have vertical semicircular grooves 54 forming the bore at the joint between the two ridge portions 6, into which a sealing material has been inserted to form a good water tight seal at the joint. These sealing grooves 60 may be moved close to the external face of the block as shown in the enlarged view of block 8 in FIG. XIII to form the bore shown in dotted lines in FIG. XII which shows a sealing strip 134 placed over the ends of the sealing means 70 in the vertical bores to provide continuous water tight seals throughout the vertical and horizontal joints in each layer of the wall.
FIG. XIV shows another form of useful block 76 comprising a basic unit block with a rectangular projection 78 extending from the external face of the block to provide a flat column fixed to the side of the wall, or just a projecting portion thereof wherever desired.
FIG. XV illustrates the use of the several different forms of blocks in building walls with rectangular corners, Ts and crosses, including rectangular stacks, and attached solid and hollow pillars, etc. The use of a multi-unit block 80, having a length five times that of the basic unit block, is illustrated in the lower left portion of this figure.
A 135 angle corner block 92 is used at one end of the wall. Block 92 is shown in FIG. XVI in perspective view.
Integral ledge portions 106 and 108 may be formed extending from the blocks internally as in block or externally as in block 77. Block 96 is a half length block of a height suitable for framing the vertical edge of an opening in a wall left open for a window or door. This block is inserted over each side edge of the opening as shown in FIG. XXII only after a sill block 98 (FIGS. XX and XXI) is inserted over the bottom edge of the opening, and another sill block 98 is then placed over the tops of the vertical frame blocks 96 to form a base support for the upper edge of the wall opening.
The half height row of blocks used for starting one of the layers of the wall at the bottom may be formed integrally with their base portions 100 as shown in FIG. XXIII, so that they may be laid simultaneously as the footing for the wall.
A solid beam such as 130 may be made with dovetail ridged ends 132 for interlocking with corresponding dovetail grooves on the internal faces of the outer layers of a wall when the beam is mounted over an upper edge of a block in the inner layer.
A flexible resilient sealing strip 134 may be used in horizontal joints between blocks or between blocks and sills, to provide good waterproofing along with the vertical seals 70 in the bores formed between the side edges of the blocks by the semicircular grooves 60. The frame and sill blocks 96 and 98 may be provided with a rectangular groove 136 for receiving rectangular sealing strips to provide sealing between the window or door not shown) and the frame of its opening.
For a multi-layered wall having more than two layers, the intermediate layers may be formed of blocks such as 164 with ridges and grooves on both faces to match the internal faces of adjacent layers. These blocks may be provided with the semicircular grooves 60 in their vertical side edges. These blocks may also be laid in any direction across a whole road bed of any width and length. Obviously, it is immaterial whether the grooves and ridges on one of the faces of these blocks are lined up as shown in FIG. XXVI) or uniformly reversely offset with respect to those on the opposite faces not shown), so as to form continuous matching ridges and grooves on the opposite faces of each layer as the blocks are laid therein.
Beams 166 for mounting horizontally between walls of the present type may be made with their end faces 168 formed like the internal face of a unit block, so that they may be mounted in place of a unit block in the inner layers 170 of the respective walls in interlocked relation with the internal faces of their outer layers 172 as may be seen in FIG. XXXI.
Instead of a solid beam, an I-beam 174 may be made with a skeletonized groove member 176 at its ends for mounting in the respective walls in interlocked relation with the corresponding ridges 178 formed in the internal faces of the outer layers of the walls.
Instead of forming grooves in the end faces of some of the beams, corresponding ridges or ridge sides may be formed thereon, such as 180 on the solid beam 182, or 184 on the ends of the I-beam 186. This provides a selectivity in the horizontal spacing of the beams in their supporting wall of half of a unit length.
The flexible resilient sealing strips 134 and rods 66 may be made of an impervious foam urethane or vinyl material. Another suitable material is a foam urethane with bituminous which has a somewhat better memory retention characteristic.
As may be readily understood from the above detailed dscriptions, this system lends itself very well to building other than straight wall structures, including artistic and architectural design uses as well as toy building blocks. Miniature size unit blocks would be very useful to architects and engineers for making sample models of their various architectual and engineering designs. Also artistic mosaic designs could be created by artists and amateurs, embryo building architects and structural engineers, who could readily try out their skills and incidentally acquire more interest to experiment with different arrangements and structural forms without necessarily resorting to expensive full size materials.
Many other obvious modifications in the detail forms and arrangements of parts in this building system may be made without departing from the spirit and scope of the present invention, as defined in the appended claim.
What is claimed is:
1. A wall construction of concrete units assembled without a binder therebetween and comprising a plurality of linear wall segments each comprising a double layer of blocks with the blocks in one layer overlapping the blocks in the other layer both horizontally and vertically, said blocks having identical horizontal sections with the inner faces of blocks in one layer having alternate and equal vertically co-extensive dove-tai1 grooves and ridges slidably interlocked with similar vertical coextensive dove-tail grooves and ridges in the inner faces of the blocks in the other layer, a corner wall segment comprising a corner block having a plurality of angularly extending block portions joined to the linear wall segments, the corner block portions each having an identical half groove and half ridge interlocked in a running fit with the inner faces of the end blocks of a layer of blocks, two spaced wall segments having a beam supported between them at points normally provided for a block in each of said wall segments, said beam having end faces formed like the interlocking inner faces of the blocks which they replace at their points of support in the respective wall segments, the dove-tail grooves and ridges on said blocks having planar faces which are positioned in face-to-face relationship when interlocked to define a close yet free fit without any noticeable play between interlocked blocks so that the wall is assembled without a binding agent between blocks.
