Definitions

  • the present invention relates to masonry building blocks, and in particular to a type of building block comprising a stone veneer.
  • the masonry wall is a very widely used wall construction.
  • a masonry wall is constructed of a plurality of building blocks, laid in courses and joined together by mortar.
  • building blocks include, but are not limited to: a stone, a cut stone having flat surfaces, a brick, a breeze block, a concrete block, a clay block and the like.
  • the building comprises inner and outer leaves.
  • the inner leaf is the load carrying structure, with the outer leaf being specified for weather proofing and appearance.
  • the typical choices are stone, brick or rendered concrete block.
  • Stone is generally regarded as the most desirable material in terms of appearance and hence property value. However, stone is costly as a material, and building with stone is slower than with blocks or bricks due to the irregular shape of undressed stone.
  • US1070281 describes a system of blocks to which stone veneers may be attached using a dry mechanical connection.
  • a building block comprising a cast concrete component and a stone component, and at least one attachment element, wherein the at least one attachment element is attached to the stone component, and wherein the at least one attachment element is secured to the stone component by adhesive, and wherein the stone component is bonded to the concrete component.
  • the at least one attachment element may comprise a dowel and one end of the dowel may be located in a hole in the stone component.
  • the at least one dowel may be of metal, such as steel, or a plastics material for example.
  • the stone component may be bonded to the concrete component by a cement bond, or an adhesive bond.
  • the density of the cast concrete component may be in the range of 1900kg/m 3 to 2100kg/ m 3 .
  • the cast concrete component may have a density falling outwit the aforementioned range so long as the resulting cast concrete component is capable of being used to build a wall following the steps of the third aspect of the invention.
  • the stone component may be longer than the concrete component.
  • the mould may be shorter in length than the stone component.
  • a wall comprising:
  • the width of the bed of mortar corresponds to the width of the concrete component of the building block.
  • the mortar between the vertical faces of the building blocks is aligned substantially with end faces of the concrete components of the adjacent building block.
  • the mortar located between the concrete components of adjacent building blocks may be a sand cement mortar.
  • the wall further comprises lime mortar in the spaces between the stone components of the building blocks forming the wall.
  • the wall may comprise a corner and the corner may include a building block having a stone component that is longer than the concrete component thereof. At such a corner, the stone component of one building block may overlap the stone component of an adjacent building block. Lime putty may be placed between the stone components of adjacent blocks where the stone components overlap.
  • a building block 1 comprises a concrete component 2 and a stone component 3.
  • the concrete component is approximately 100mm deep and the stone component is approximately 20mm deep.
  • the whole building block 1 is approximately 440mm in length, which is the length of a standard concrete building block.
  • the building block includes steel dowels 4.
  • two steel dowels are provided.
  • the steel dowels are situated inwardly of respective end faces 2a, 2b of the block 1.
  • the dowels are situated approximately 150mm inward from the respective end faces.
  • the stone component 3 is provided with a hole 5 shaped and dimensioned to receive one end of the steel dowel 4.
  • the steel dowel 4 is secured in the hole 5 with a stone adhesive.
  • the block 1 is formed by casting with a poured concrete mix.
  • the stone component 3, with the steel dowels 4 glued in place in the holes 5, is placed in the bottom of a mould. Concrete is then poured into the mould to the required depth (100mm in the illustrated embodiment). The concrete bonds to the surface 3a of the stone component and to the steel dowels 4.
  • Figures 5 and 6 illustrate a corner block 1' in which the stone component 3' extends beyond the end face 2a' of the concrete component 2'. This provides a rear face region 3a' of the stone component 3', the purpose of which is to cover the end face 2a of the block 1 in a wall construction.
  • Figure 8 illustrates the corner block 1' in such a wall construction.
  • Figure 7 illustrates a wall comprising a first course of building blocks 1 and a second course of building blocks 1 with a layer of mortar 7 therebetween.
  • the layer of mortar 7 covers only the concrete part of the building block.
  • the mortar 7 is a sand and cement mortar, which is the appropriate type of mortar for bonding two concrete components together.
  • a sand and cement mortar is not appropriate for use between the stone components 3 of the block 1.
  • the region 8 between the stone components of the building blocks 1 is left unfilled.
  • the regions 8 are pointed to give a weather proof and aesthetically pleasing finish.
  • the regions 8 are pointed with a lime and sand mortar.
  • a lime and sand mortar is more flexible than a sand and cement mortar.
  • the lime and sand mortar allows differences in expansion and contraction with temperature (concrete and stone have different coefficients of thermal expansion and contraction) to be taken up. Furthermore, moisture taken up by the stone during rain events for example, may be dissipated through the lime and sand mortar, whereas sand and cement mortars tend to trap moisture.
  • Figure 8 illustrates a wall including a corner constructed of building blocks 1 of Figures 1 to 4 and building blocks 1' of Figures 5 and 6 .
  • part of the rear face 2c of the concrete component 2 of block 1 overlaps the end face 2a' of the concert part 2' of block 1'.
  • a layer of mortar 8 is located between the end face 2a' and the rear face 2c.
  • the mortar 8 would be placed on the end face 2a', with the rear face 2c being presented up to and pressed against the mortar 8 by the builder laying the blocks.
  • the stone component 3' is shaped and dimensioned so that the whole end face of the block 1 is overlapped.
  • a small amount of lime putty is placed between the rear face part 3a' and the end face 2a of block 1.
  • the end face 3c of the stone component 3 is also covered by the stone component 3' of block 1'. Where stone overlaps stone, the stone is wetted prior to application of lime putty.
  • the lime putty creates adhesion between the stone component 3' of block 1' and the both the concrete and stone components 2, 3 of the block 1.
  • Figures 9 and 10 illustrate moulding equipment used for creating the building blocks 1, 1'.
  • the mould 11 of Figure 9 sits on top of the stone component 3, to which the dowels 4 have been attached.
  • the mould 11 comprises side walls 11a and end walls 11b.
  • the internal shape and dimensions of the mould 11 correspond to the external shape and dimensions of the stone component 3.
  • the mould 12 of Figure 10 sits on top of the stone component 3', to which the dowels 4' have been attached.
  • the mould 12 comprises side walls 12a, a first end wall 12b and a second end wall 12b'.
  • the side walls 12a are shorter than the stone component 3' so that concrete is poured in the mould over only a part of the stone component.
  • the mould 12 sits over a part of the stone component 3'.
  • the internal width of the mould corresponds to the external width of the stone component and the internal surface of the end wall 12 is aligned with the external edge of the stone component 3'.
  • the resulting building blocks 1, 1' provide a stone face with much reduced cost when compared to a solid stone block of the same size.
