Definitions

  • THIS invention relates to an interlocking building block.
  • Many building blocks have projecting formations on a first side and corresponding recesses on an opposite, second side for interlocking adjacent blocks relative to one another so as to form a structure.
  • a problem associated with many of the known interlocking building blocks is that adjacent blocks in a structure formed from such blocks generally bear directly against one another, without any cementitious material between the blocks. Since the interlocking formations are usually designed with a tolerance, the adjacent blocks are often subjected to small relative movements with respect to one another due to, for instance, differential settlement of the structure. If the structure is covered with a layer of plaster, the relative movement between the building blocks can result in the development of cracks in the plaster.
  • an interlocking building block having a projection on a first side thereof and a complementally interlocking recess on an opposite second side thereof, the projection forming at least one upstanding cruciform shape, wherein at least one edge region of the block includes a recess which, when the block is interlocked with an adjacent similar block, forms an exposed groove at the interface between the edge regions of the adjacent blocks.
  • the exposed grooves formed at the interface between the edge regions of adjacent blocks can be filled with a cementitious, fibrous material for absorbing relative movement between the adjacent blocks.
  • a plurality of recesses are formed along edge regions of the first side of the block between end portions of the projection.
  • the block may include a corner recess along at least one of the corners of the block separating the first side from the opposite second side.
  • the sides of the block separating the first side from the opposite second side may include at least one side groove extending from the first side to the opposite second side.
  • the projection on the first side has bevelled edges and includes at least one projection groove between the bevelled edges.
  • reinforcing material may be received in the side grooves and the projection grooves of a wall formed from the blocks so as to secure the blocks to one another.
  • Tie rods may also be inserted into the side grooves and the projection grooves to secure a portion of a roofing structure, or the like, to the wall.
  • the second side of the block may include at least one cavity for reducing the weight of the block.
  • Figure 1 shows a perspective view of an interlocking building block according to the invention
  • Figures 2 to 4 show a plan, underplan and side view respectively of the building block of Figure 1 ;
  • Figure 5 shows a partial perspective view of a corner of a wall constructed from building blocks according to the invention.
  • Figure 6 shows a partial perspective view of a wall constructed from building blocks according to the invention.
  • FIG. 1 to 4 of the drawings there is shown an interlocking building block 10 for constructing various structures.
  • the block 10 is generally rectangular in shape and has standard dimensions.
  • a projection 12 extends across a first side 14 of the block 10.
  • the projection 12 comprises a longitudinal rib 16 extending across the length of the side 14, and two transverse ribs 18 and 20 extending across the breadth of this side, and intersecting the longitudinal rib to form cruciform shapes as illustrated.
  • the edges 22 of the projection 12 are bevelled at approximately 45° to the plane of the first side 14.
  • a second, opposite side 24 of the block 10 has a recess 26 corresponding complementally to the projection 12 for interlocking adjacent blocks 10 relative to one another.
  • the dimension B (see Figure 2) is twice as great as the dimension A so that when a series of the blocks 10 are placed longitudinally side by side, a substantially continuous longitudinal projecting rib with equally spaced transverse projecting ribs is formed.
  • This allows a plurality of blocks 10 to be stacked in a stretcher bond fashion (as illustrated in Figure 6) or in stacked relationship (not illustrated).
  • the blocks 10 can be stacked to form a corner arrangement as illustrated in Figure 5.
  • Side grooves 34 extend from the ends of the ribs 16, 18 and 20 on the first side 14 of the block 10 to the ends of the recessed sections 28, 30 and 32 of the recess 26 on the second side 24 of the block.
  • There are projection grooves 36 extending along the ribs 16, 18 and 20 of the projection 12 with edges 38 sloping at approximately 45° to the plane of the base 40 of the grooves 36.
  • End walls 42 separate the projection grooves 36 from the side grooves 34.
  • the side 24 of the block 10 has recess grooves 44 in the recessed sections 28, 30 and 32 of the recess 26, which correspond with the projection grooves 36.
  • End walls 46 separate the recess grooves 44 from the side grooves 34.
  • continuous grooves extending around the block 10 can be formed for receiving reinforcing wire, tie rods or the like. These continuous grooves are particularly useful for securing a member such as a portion of a roof structure (not illustrated) to the top of a wall constructed from the building blocks 10.
  • the continuous grooves can also be used for securing adjacent blocks to one another or for securing members in general to a wall formed from the blocks.
  • the groove 34 on the edge 48 is dimensioned to correspond to the dimensions of the side edge of a standard window frame fitting. In this way, the installation of a window frame into a wall constructed from the building blocks 10 is simplified.
  • the cavities 49 There are two cavities 49 in the second side 24 of the block 10 for reducing the overall weight of the block.
  • the cavities 49 have inclined side walls extending from the side 24 towards the side 14.
  • the depth of the cavities varies according to the amount of weight reduction required so that the cavity extends a quarter of the distance to the side 14 for "heavy weight” blocks, half of the distance to the side 14 for “medium weight” blocks and three quarters of the distance to the side 14 for "light weight” blocks.
  • Recesses 50 extend between the ribs 16, 18 and 20 of the projection 12, along all of the edge regions of the side 14 except for the edge 48, and corner recesses 51 extend between the sides 14 and 24 at the corners of the block 10.
  • the purpose of the recesses 50 and corner recesses 51 is to reduce the extent of the development of cracks in a layer of plaster covering a wall constructed from the blocks 10.
  • FIG. 6 of the drawings there is shown a portion of a wall 52 constructed from the blocks 10.
  • the blocks 10 have been stacked in stretcher bond fashion and the interlocking projections 12 and recesses 26 ensure that the blocks 10 are substantially secured in position relative to one another.
  • the relevant end walls 42 and 46 in the blocks 10 of rows A and B in the wall 52 have been broken away and tie rods 54 have been inserted into the recesses consequently formed between these two rows.
  • the tie rods 54 extend above the top of the wall 52 for securing a member (not illustrated) forming part of a roof structure to the top of the wall.
  • the recesses 50 and corner recesses 51 form grooves 56 between adjacent blocks 10 in the wall 52.
  • a levelling coat 58 is applied to the wall to conceal the exposed grooves 34, and 56, and the tie rods 54, and to produce a smooth finish to the wall.
  • the levelling coat 58 comprises a cementitious product including a fibrous material, such as PT KOLORPLAST FILLER COAT manufactured by Plastertech (Ry) Ltd.
  • a very thin layer, typically between 1 mm and 5 mm, of the levelling coat 58 is applied to the wall 52 by trowel. As the filler coat 58 is applied to the wall, it penetrates and fills the grooves 56 to provide a number of strips of filler material between the edge portions of adjacent blocks 10.
  • These strips of filler material adhere adjacent blocks 10 to one another and absorb, at least to some extent, relative movement between the adjacent blocks which may result from differential settlement, shrinkage or the like, and thereby reduce the extent of the development of cracks in the wall coating attributable to such relative movement.

Abstract

La présente invention concerne un bloc de construction à emboîtement (10) comprenant une saillie (12) sur sa première face (14) et un évidement à emboîtement (26) complémentaire sur sa deuxième face opposée (24). La saillie (12) se présente au moins sous une forme cruciforme verticale dans laquelle au moins une zone de bord du bloc comprend un évidement qui, lorsque le bloc est emboîté avec un bloc adjacent similaire, forme une rainure exposée (56) sur l’interface entre les zones de bord et les blocs adjacents. De cette manière, lorsqu’une structure telle une paroi est obtenue à partir des blocs de construction, les rainures exposées formées sur l’interface présent entre les zones de bord des blocs adjacents peuvent se remplir d’un matériau fibreux cimentaire destiné à absorber les mouvements relatifs entre les blocs adjacents.
