Definitions

  • the present invention relates to a building block and more particularly (but not necessarily exclusively) to such a block for use in constructing a dry-stacking high performance masonry wall.
  • the invention also relates to a method of producing the block.
  • the invention relates to a one piece integrally moulded (or cast) building block used for producing a wall with internal voids.
  • the block is of the type comprised of parallel walls that are transversely spaced from each other so that adjacent walls have opposed inner surfaces and further comprised of at least one cross-wall connecting the opposed inner surfaces of the parallel walls.

  • FIG. 1 a third set of two cross-walls 8 connecting the facing surfaces of the inner walls 4 and 5 to each other.
  • the cross-walls 6 and 7 are provided one at each end of the block 1 and one centrally thereof whereby two voids 9 are defined between each adjacent pair of inner and outer walls.
  • the two cross-walls 8 are provided at the quarter points of the length of the block so that a void is defined between the inner walls 4 and 5 of the block together with two "part-voids" 1 1 which are open at the ends of block 1.
  • All cross-walls 6-8 are formed in their upper surface with a V-shaped notch 12 - see Fig 2 which is a view looking in the direction of arrow X of Fig 1 . As shown in Fig 2, the V-shaped notch extends downwardly from the level of the upper surfaces of the various walls 2-6. Similarly for the notches in cross-walls 7 and those in cross- walls 8.
  • the upper surfaces 13 of the outer walls 2 and 3 are below the level of the upper surfaces 14 of the inner walls 4 and 5.
  • the upper surfaces 13 (of outer walls 2 and 3) are provided with bosses 25 which at their tops are level with upper surfaces 14 (of inner walls 4 and 5).
  • vertical rebates 26 are provided in the outer walls 2 and 3 at each side edge thereof.
  • blocks 1 are laid to construct a wall. Briefly however the blocks of any one course are laid end-to-end so that the "part-voids" 11 of two blocks form a "full void” similar to voids 9 and 10. Blocks 1 in successive courses are half-bonded relative to those in the vertically adjacent course so that the voids are in vertical alignment.
  • the bosses 25 provide for stability during dry-stacking of the blocks 1 and serve also to define horizontal bed joints, vertical (or "perp") joints being defined by the rebates 26.
  • the blocks 1 may be of concrete and are cast in a mould sub-divided into four chambers (one for forming each of the walls 2-5) by three partitions. These partitions are associated with passageways to provide communication between adjacent sub- chambers to allow formation of the cross-walls 6-8 in conjunction with. V-shaped profiles provided within the upper regions of the passageways for producing the V- shaped notches 12.
  • concrete or other solidifiable material
  • the moulding operation concrete (or other solidifiable material) is introduced into each of the four sub-chambers through rectangular aperatures in a surcharge plate, these rectangular apertures registering with the upper rectangular openings of the sub-chambers. Subsequently the concrete in the sub-chambers is compressed using means which are of the same rectangular size as the sub-chambers.

  • the upper surfaces of the parallel walls are those surfaces (also know as bed surfaces) which are uppermost when the block is laid and not necessarily upper surfaces when formed in the mould.
  • the end regions of the cross-wall are compacted wholly below the upper surfaces of the parallel walls.
  • a one piece integrally moulded building block comprised of parallel walls that are transversely spaced from each other so that adjacent walls have opposed inner surfaces and further comprised of at least one cross-wall connecting said opposed inner surfaces of the parallel walls, the cross-wall incorporating intermediate its end regions a recess in its upper surface wherein the end regions of the cross-wall are compacted wholly below the upper surfaces of the parallel walls.
  • the upper surfaces of the end regions of the cross-wall are flat and extend perpendicularly to the major faces of the parallel walls.
  • the upper surface of the end region of the cross-wall will be about 23-27mm below the upper surfaces of the top walls for a block having a depth of 100mm.
  • the lower surfaces of the cross-wall will be flush with the lower surfaces of the parallel walls.
  • the recess in the cross-wall may be semi-circular along its length although other configurations (e.g. U-shape) are possible.

Abstract

L'invention concerne un procédé de moulage, à partir d'un matériau apte à la solidification, d'un bloc (101) de construction constitué de parois parallèles (102-105) espacées transversalement les unes par rapport aux autres de telle sorte que des parois adjacentes présentent des surfaces intérieures opposées, et constitué en outre d'au moins une paroi transversale (106-108) qui relie lesdites surfaces intérieures opposées des parois parallèles (102-105) et qui incorpore entre ses régions d'extrémités un évidement (116) s'étendant suivant la largeur de la paroi transversale. Le procédé comporte les étapes consistant à introduire le matériau apte à la solidification dans un moule (200) où les surfaces supérieures des parois parallèles (102-105) et les régions d'extrémités de la paroi transversale (106-108) sont formées dans des parties du moule (200) ouvertes sur le dessus, à effectuer un compactage du matériau apte à la solidification à travers lesdites régions ouvertes sur le dessus et à solidifier ledit matériau.
