AZAR, a Canadian citizen of 1038 Lesperance Road, Tecumseh, Ontario, N8N 1W8, Canada 329270 NEW ZEALAND PATENTS ACT, 1953 No: Date: N.Z. i-.^TENT OFFICE ~ 2 OcC 1997 CElVrr, COMPLETE SPECIFICATION CONCRETE BUILDING BLOCKS I, TONY J. AZAR, a Canadian citizen of 1038 Lesperance Road, Tecumseh, Ontario N8N 1W8, Canada do hereby declare the invention for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement: (followed by page -la-) 329 2 7 CONCRETE BUILDING BLOCKS Field of the Invention The present invention relates to the field of building blocks, in particular concrete building blocks. The present invention provides a novel dry stack building block, in a stretcher embodiment, and a corner embodiment.
Background of the Invention Building blocks, in particular concrete building blocks, are used extensively in the construction of walls, both below grade in the case of foundation walls, and above grade, in the case of structural walls. Concrete blocks generally have hollow cores, planar, rectangular faces, and rectangular ends and upper and lower surfaces. They are ordinarily stacked in a stretching bond pattern, with mortar between each course of blocks, and between each block in a course. As required, rebar may be inserted in the cores of the blocks, after stacking, and the cores may be filled with concrete. There have, moreover, been attempts to develop concrete blocks with dry stacking capability. For instance, in U.S. Patent No. 5,230,194 to McClure, a block is described with front and back faces that are offset slightly from the upper and lower surfaces, and the ends of the block. This feature permits the blocks to be dry stacked and interlocked. However, no satisfactory 3,2 9.ZJ.Q a corner is disclosed by McClure, who instead discloses an L-shaped corner suitable for one-way, right or left usage.
In U.S. Patent No. 4,597,236 (Braxton), a dry-stack block is disclosed that relies on the use of spines insertable between blocks in a stacked wall. Braxton discloses corners constructed from blocks that are smaller than the remaining blocks in this system, and which do not permit the use of a stretcher bond pattern of block laying.
In view of the foregoing, the object of the present invention is to provide a novel dry stacking, interlocking concrete block that has a stretcher and corner embodiment of similar overall dimensions. Such a block can be utilized to dry stack a wall, with such corners as are desired by the 15 builder rather than dictated by the block, in the traditional strong stretcher bond pattern of block laying; ana/or to provide a dry stack block that is provided with a surface that is grooved to permit fast and efficient drainage from the faces thereof; and/or to provide the public with a useful choice. h'LVt-i In a broad aspect, then, the present invention relates to a building block having opposite first and second ends and comprising first and second substantially congruent rectangular panels extending between said ends of said block, said panels being joined together by at least one web extending transverse to said panels, said panels each having vertical end edges at the respective first and second ends of the building block, the end edges being notched to interfit with end edges of panels of an adjacent block in a vertical joint therewith, the notches being vertically extending on the respective end edges and being disposed such that at the first end of said block, the notch on the first panel is on an inside corner and the notch on the second panel is on an outside corner and such that at the second end of said block, the notch on the first panel is on an outside corner and the notch on the second panel is on an inside corner.
Brief Description of the Drawings In drawings that illustrate the present invention by way of example: Figure 1 is a perspective view from the underside, of a stretcher block according to the present invention; Figure 2 is a top view of the block shown in Figure 1; Figure 3 is an underside view of the block shown in Figure 1; Figure 4 is a side view of the block shown in Figure l; Figure 5 is one end view of the block shown in Figure i; Figure 6 is the other end view of the block shown in Figure 1; Figure 7 is a perspective view, from the underside, of a corner block according to the present invention; Figure 8 is an underside view of the block shown in Figure 7; 329270 Figure 9 is a top view of the block shown in Figure 7; Figure 10 is a view of one side of the block shown in Figure 7; Figure 11 is a view of the other side of the block shown in Figure 7; Figure 12 is a view of one end of the block shown in Figure 7; Figure 13 is a view of the other end of the block shown in Figure 7; Figure 14 is a top view of a corner constructed with a stretcher block and corner block according to the present invention; and Figure 15 is a top view of a T-intersection constructed with two stretchers and a corner block according to the present invention, with the stretchers illustrated slightly separated from the corner to better shown the joints between the stretchers and corner blocks.
Detailed Description Referring now to Figure 1 - 6, the basic concrete stretcher block 1 according to the present invention is illustrated. It comprises a front face 2, and rear face 3, which are substantially identical and interchangeable. The faces 2,3 are provided on their surfaces with grooves 4 that extend vertically, and serve to channel water from the face 4- 329 27 0 of the blocks. The presence of grooves 4 is especially important for sub-grade applications, in which fill has been compacted against the exposed face of the blocks.
The faces 2,3 are joined together by webs 5, each of which has a broad outer ends 6 that taper inwardly to a narrower central portion 7. The thickened outer ends 6 of the webs 5 provide increased stability for the blocks during curing, while the narrower central portions of the webs advantageously permit the blocks to be lightened in weight, while providing adequate support during curing. Referring to Figures 5 and 6, it will also be noted that the central portion of the web is provided with a shallow channel 8 along its upper and lower surfaces. The purpose of these channels is to permit concrete that is poured into the interior of a wall constructed with the blocks of the present invention to flow between the blocks, and thereby lock adjoining blocks together securely upon curing.
As best illustrated in Figures 1, 5 and" 6, the front and rear faces 2,3 of the blocks protrude downwardly slightly from the lower surface 9 of the webs 5. The upper surface 10 of the webs 5 and the adjoining body 11 of the block extend upwardly slightly from the faces 2,3 of the block, in a complementary shape, to permit a stretcher 1 to .329 2 7 0 interlock with another stretcher along the upper and lower surfaces thereof.
Referring to Figures 1, 2 and 3, it will be seen that the ends of the stretcher block of the present invention are provided with offset square notches 12. By the term "offset" is meant that the notch 12 on one face of an end will be on the outside of the block face, while the notch on the other face of the same end will be on the inside of the block face, as can be seen in Figure 2'^or 3. By offsetting such notches 12, any two stretchers may be placed in adjoining relation, without orienting either face 2,3 of the block in a particular direction. The notches also serve to interlock the stretcher blocks with the corner blocks, as will be explained below.
With reference to Figures 7-13, the present invention provide a corner block 13, for use with the stretcher block of the present invention. The corner block 13 has side faces 14, 15 corresponding to the front and rear faces 2,3 of the stretcher. The side faces of the corner block are provided with grooves 4 similar to the grooves en the stretchers 1. Moreover, squared notches 16 are also formed in the side faces 14, 15 of the corner block, spaced apart so as to interfit with the notches ends of the stretchers, 3292 / as can be seen in Figures 14 and 15. It will be noted, moreover, that the notches 16 formed in one face of the corner block are offset relative to the notches formed in the other face. This arrangement permits a stretcher 1 to be interfit with a corner block on either side of same, whereby T junctions can be formed, as shown in Figure 15. Also, with this arrangement it is not necessary to provide a different block for right and left corners, also as illustrated in Figure 15.
Directly beneath each notch 16, in the vertical face of the corner block is formed a notch 17, the function of which is to permit corner blocks to be stacked vertically at right angles to one another in a chimney bond pattern, to form the corner of a wall.
The ends of the corner blocks 13 are notched in ,a manner similar to the stretcher blocks 1, to permit interfit therewith.
The blocks of the present invention may be fabricated from any suitable concrete, as will be a matter of choice for one skilled in the art.
