DESCRIPTION:
BRIEF SUMMARY
This invention relates to an improved building block or panel.
There have been numerous attempts to provide building blocks or panels with interlocking edges which can be assembled without the need for bonding agents to form walls and similar structures. One such interlocking block is described in my Australian Pat. No. 274695. Whilst this interlocking block proved to be satisfactory in use, it has now been found that by providing diagonally opposite corners of a rectangular or square block or panel with recesses which extend around the corner and by providing the other pair of diagonally opposite corners with projections, the blocks or panels can be locked together in a manner which gives considerable strength in a wall structure to provide a wall structure which can resist forces applied transversely to the wall. In addition, the block of Pat. No. 274695 required a high degree of precision which was unacceptable to conventional manufacturing practice.
In one form the invention resides in a building block or panel having the shape of a right parallelepiped having two opposed major faces, the remaining faces being edge faces which are formed to interlockingly engage with the edge faces of similar building blocks wherein two pairs of adjacent edge faces at opposed sides of the block are each formed with an elongate recess extending from and through the respective corner of said adjacent edge faces to an intermediate location on each edge face, each edge face also being formed with an elongate projection which is able to be received in the recess of a corresponding block; the one end of each projection adjacent the respective recess being contoured to define at least a portion inclined at an angle of less than 90.degree. between the face and the base of the respective recess wherein the other end of each projection has a face of a complementary configuration. dr
The invention will be better understood by reference to the following description of one specific embodiment of the invention shown in the accompanying drawings wherein:
FIG. 1 is a side elevation of one block;
FIG. 2 is an inverted plan view;
FIG. 3 is a section of line 3--3 of FIG. 1;
FIG. 4 is a perspective view;
FIGS. 5A and 5B illustrate two further alternatives of blocks according to the invention;
FIG. 6 illustrate alternative cross-sectional configurations of the groove and elongate projection of blocks according to the invention; and
FIGS. 7A and 7B illustrate two alternative profiles of blocks according to the invention.
The embodiment as shown in the drawings is directed to a building block having the shape of a right parallelepiped having two opposed major faces 11 which are substantially square, separated by four edge faces which are rectangular. Each edge face is formed with a recess 13 of a V-shaped configuration extending approximately half the length of each face and wherein the recesses of a pair of adjacent edge faces open into each other at the corner. At the diagonally opposite corner the recesses of the respective edge faces also open into each other. The remaining portion of each edge face is formed with a projection 5 having a cross-sectional configuration which is complementary to the recess 13 such that it would be fully received in the recess of a corresponding block. At the junction of the recess 13 with the projection at each edge face the end face 17 so formed, is substantially planar, is transversely positioned across the edge face and forms an acute angle of approximately 45.degree. or greater with the base of the recess to overlie the recess. The other end 19 of each pair of projections 15 which are adjacent the corners of the block are planar and are formed to define an angle which is complementary to the angle at the junction end 17 of the projection (ie; 45.degree. or less). The adjacent other ends 19 of the projections 15 of a pair of adjacent faces are substantially co-planar.
On location of the blocks in position the projections on one block are received in the recesses of the adjacent blocks and due to the comp
