Abstract

The building unit 10 for constructing two walls simultaneously, i.e. a cavity wall, comprises a first and second block 12, 13 coupled together via a coupling member 14, such as a metal rod, extending between the first and second blocks. Each of the blocks may form a face of each of the walls. The second block may provide thermal or acoustic insulation. The blocks may be made from curable material and be arranged to cure within a pair of moulds with the metal rod extending within the moulds. Tension may be applied to the metal rod as the blocks are curing, and after the blocks have cured the tension is released creating a compressive stress within the blocks. Also claimed is a method for building two walls by laying the units on top of each other. The method may also comprise injecting insulating foam into the space between the two walls.

Description

Building Unit The present invention relates to a buiJding unit for a wall and to a method of building a wall, and particularly but not exclusively, to a building unit for a cavity wall and to a method of building a cavity wall.
Modern buildings require minimum standards of heat and sound insulation. These requirements are typically achieved by building so-called cavity walls, whereby a face wall of the building is separated from an internal wall by a narrow cavity. The face wall is typically constructed from a masonry brick which is an absorbent material and will thus absorb rainwater for example into the wafl. The cavity serves as a way to drain this water back out through weep holes in the base of the wall system and thus prevents rainwater from penetrating into the building.
The internal wall is typically constructed from an insulation block, such as a Thermalite� block, which acts to retain heat within the building. The cavity provides the ability to further insulate the building by placing an insulation material within the cavity.
The face and internal walls of the cavity wall are built separately, but are arranged to extend substantially parallel with each other around a periphery of the building. In addition, the cavity wall is built with wall ties that extend between the face and the internal wall, to provide an increased strength to the cavity wall. However, the building of two separate walls coupled with the need to position ties at regular intervals along each wall, renders the build a time consuming process.
I have now devised a building unit and method of building a cavity wall which alleviates the above-mentioned problems.
In accordance with a first aspect of the present invention there is provided a building unit for building a first and second wall simultaneously, the unit comprising a first and second block arranged in spaced relation, the first and second block being coupled together via coupling means which extends between the first and second block, wherein the first and second blocks comprise elements of the first and second wall.
Preferably, the first and second blocks are substantially the same shape, and preferably extend substantially parallel to each other.
Preferably, the first block comprises a face block having a face surface that forms a face of the first wall.
Preferably, the second block comprises an insulation block, for providing thermal insulation. Alternatively, or in addition thereto, the insulation block preferably provides acoustic insulation.
Preferably, the coupling means is arranged to stress the first and second block into a compressive state.
The coupling means preferably comprises at least one metal rod, which extend into the first and second block.
The first and second blocks are preferably formed of a settable material or a curable material, for example that is arranged to set or cure within a first and second block mould. Preferably, the metal rod or rods are arranged to extend within the first and second mould and a tension is applied and maintained to the metal rod or rods, while the material of the first and second blocks sets or cures within the first and second mould.
Preferably, the tension is released from the rod or rods following the setting or curing of the first and second block, creating a compressive stress within the first and second block.
Preferably, the or each metal rod is a steel rod.
Preferably, the first and second walls form a cavity wall.
In accordance with a second aspect of the present invention, there is provided a method of building two walls simultaneously, the method comprising the use of a plurality of building units according to the first aspect, the method comprising the steps of placing one building unit upon another building unit such that the first block associated with the one unit extends over the first block associated with the other unit, and the second block associated with the one unit extends over the second block associated with the other unit.
Preferably, the method further comprises inserting an insulation material into the space between the first and second wall.
Preferably, the insulation material comprises a foam that is injected into said space.
In accordance with a third aspect of the present invention, there is provided a cavity wall, the cavity wall comprising a plurality of building units according to the first aspect.
An embodiment of the present invention will now be described by way of example only and with reference to the accompanying drawings, in which: Figure 1 is a perspective view of the building unit according to an embodiment of the present invention; and, Figure 2 is a perspective view of a section of a wall according to an embodiment of the present invention.
Referring to figure 1 of the drawings, there is illustrated a building unit 10 according to an embodiment of the present invention for building a cavity wall 11, for example of a building (not shown). The unit 10 comprises first and second building blocks 12, 13 that are coupled together via a plurality of metal rods 14 such as a plurality of steel rods, for example. The first block 12 may comprise a brick or face block which forms a face wall of the cavity waIl 11, whereas the second block 13 may comprise a thermal block which forms the internal wall 16 of the cavity wall 11, which serves to retain heat within the building (not shown).
The building blocks 12, 13 are substantially rectangular cuboid in shape and comprise a substantially square end faces 17 that extend substantially in the yz-plane, as illustrated in figure 1. The metal rods 14 extend from the first block 12 of the unit 10, out from one of the rectangular side faces 18 thereof that extend substantially in the xz-plane, in a direction substantially perpendicular thereto. Each rod 14 passes into the second block 13 through a rectangular side face 18 of the second block 13 that also extends in the xz-plane and which is arranged substantially adjacent the side face of the first block 12.
The rods 14 are held between the first and second block 12, 13 in a stressed state which maintains each block 12, 13 in a state of compression. This is achieved by forming the first and second blocks 12, 13 around the metal rods 14 while the rods 14 are held in a state of tension. The first and second blocks 12, 13 are formed of a settable or curable material, for example, that is held within a first and second block mould (not shown). The metal rods 14 are arranged to extend within the first and second moulds (not shown) and a tension is applied and maintained to the metal rods 14, while the material of the first and second blocks sets or cures within the first and second mould (not shown).
Once the blocks 12, 13 have set, cured or otherwise solidified, the tension in the rods 14 is released. The elasticity associated with each rod 14 biases the rod 14 to its initial shorter length and thus stresses the blocks 12, 13 into a compressive state. This pre-stressing of the rods 14 provides for a more rigid unit 10 that is more resistive to tensile stresses.
The wall 11 according to an embodiment of the present invention is illustrated in figure 2 of the drawings. The wall 11 is constructed by placing a row of units 10 upon a base foundation 19 that has been prepared with a layer of mortar 20, such that the square ends faces 17 of the first and second block 12, 13 of one unit 10 are arranged substantially adjacent the square end faces 17 of a neighbouring unit 10 respectively, so as to form a first row 21a of first blocks 12 and a first row 21b of second blocks 13.
A layer of mortar 20 is then placed upon the first row 20 of first and second blocks 12, 13 and a further row of units 10 is placed upon the first row 21, such that the first blocks 12 associated with the second row 22a extend over the first blocks 12 associated with the first row 21 a, and the second blocks 13 associated with the second row 22b extend over the second blocks 13 associated with the first row 21b, as illustrated in figure 2 of the drawings. In this manner, two walls 15, 16 are formed simultaneously and are tied together by the metal rods 14.
From the foregoing therefore, it is evident that the building unit of the present invention provides for a simple yet effective means of constructing a cavity wall.
