Definitions

  • This invention relates to a polyhedral, composite building unit comprising an integrally formed first component of ceramic or vitreous material or natural or synthetic stone at least one face of which will be exposed on one side of a wall in which the unit is incorporated, in use, and a second component comprising cementitious material, cemented to the first component and having better therms lly insulative properties than the first component.
  • a common way to achieve heat insulation is cavity wall construction.
  • an external wall of porous material such as relatively low- grade, common brick the cavity serves the additional and more important purpose of preventing water ingress.
  • the external brick wall becomes saturated the cavity acts as a vapour barrier.
  • measures which are adopted to increase heat insulation after a building has been constructed such as filling the cavity with a settable, heat insulating foam, can be counter-productive. These measures have in any event come into disrepute. Poisonous or noxious emission into the building interior can occur when certain foams are used.
  • a cavity wall consisting of two leaves or skins of brick without plaster or other lining would present a fair-faced interior.
  • a brick interior is often specified by the client, but the standard 105 mm brick used to build two walls with a 50 mm cavity or spacing would not comply with e. g. British building regulations, which require a heat transmittance value across the wall (hereinafter referred to as the " ⁇ value') of less than 0.6 w/m 2 deg. C.
  • the internal leaf or skin of a cavity wall is more commonly provided by building it not out of brick but by laying brieze blocks or blocks of thermally insulating concrete. These are cheap to produce and blocks of substantial thickness can be used because the material is relatively light in weight.
  • the required J1 value is easily achieved, but such inner walls certainly are not aesthetically acceptable, so that subsequent rendering or plastering or some other form of lining is in almost all cases essential.
  • a cavity wall which will have the required J1 value may be constructed with an inner leaf or skin consisting of a timber frame supporting a thermal insulation material, say 100 mm thick. This however will require a finish or lining of plasterboard.
  • a single-leaf wall constructed from 150 mm blocks of thermally insulating concrete lined internally e. g. with vermiculite plaster or a dry lining could comply with building regulations but it is rarely used in the construction of habitable dwellings in cool climates. It would require a weather- and waterproof external render. The application of such a render would involve high labour costs and the finished building, having an unfamiliar appearance, would not on the whole be acceptable to conservative customers and planning authorities.
  • a hollow, load-bearing concrete structure can be filled with a (weaker) concrete mixture with better heat insulating characteristics, as exemplified in British Patent Specifications Nos. 1 252 562 and 1 525 238 which also suggest that cavities may be left open (in the latter event resembling so-called "air bricks', which are bricks formed with through-openings to provide ventilation when included with solid bricks in a wall).
  • French Patent Specification No. 1 524 275 states that it is known to produce cement blocks pre-faced with stone, using the stone slabs as a slip base for casting the cement blocks.
  • This Patent Specification proposes the improvement of utilising special metal ties to reinforce the connection between the concrete blocks and facing slabs of stone. Individual stone slabs to face individual faces of the block have recesses formed in them to accept opposite ends of a metal tie which extends outwardly from the rear of the slab. When concrete is poured into a mould lined with the slabs, their ties projecting into interior of the mould, the ties become embedded in the concrete.
  • U.S Patent Specification No. 3 905 170 discloses light-weight composite slabs with tongue-and-grooved edges for the prefabrication of buildings, an improvement upon heavier concrete slabs. These cementitious slabs may be lined on external surfaces with brick veneer plates to imitate a brick wall, but no method of bonding the plates to the cementitious base is disclosed other than by cementitious bonding as in the case of tiles applied to a plaster wall.
  • Belgian Patent Specification No. 532 740 discloses the manufacture of a "monolithic block".
  • a thermally insulative core is moulded between harder and less porous outer layers, which may fully surround the core.
  • ceramic facings may be attached to the outer layers, but again no special means is described for so doing.
  • the invention as claimed is designed to overcome the problems of previous proposals.
  • an integral unit is provided having the shape and dimensions of a standard brick and adapted for use in conventional brick-laying techniques. This avoids the resistance of the consumer to the adoption of wholly new building techniques and permits the provision of a traditional-looking brick- laid wall without, however, the problems inherent in the latter as above discussed.
  • the fair-facing and the thermally insulative components of the unit of the invention are mechanically coupled, so that reliance is not placed wholly on a cementitious bond between flat surfaces, but at the same time metal ties or other extraneous devices are dispensed with.
  • a composite unit which has the overall shape and dimensions of a conventional house brick and which may be used in the same way in the construction of a wall, i. e. it may be laid with other, similar units, with or without the interposition of mortar, according to established brick-laying techniques.
  • the unit does not consist entirely of clay.
  • a conventional concrete block it does not consist entirely of concrete.
  • it is made up of two components: (a) a box-like enclosure the base 18 of which constitutes one of the longer sides 38 of the unit and (b) a body 11 of cementitious material contained by and hydraulically and mechanically bonded to the enclosures 10.
  • the principal purpose of the enclosure 10 is to give to the unit, when included in a wall, the appearance of a traditional building material and for this reason it is prefabricated from a ceramic material, such as fired clay, from a vitreous material, such as glass, or from natural or synthetic stone.
  • the box-like shape can be achieved by building the enclosure 10 from separate pieces e. g. of stone or fired clay or by moulding wet clay, heat softened glass or a synthetic stone mixture to the shape illustrated prior to firing, hardening or setting.
  • the enclosure 10 preferably has inwardly directed lips or flanges 16 at the free end edges of its four “walls” such as 12 and 14.
  • additional flanges, ribs or protrusions such as indicated in phantom lines at 17 in Figure 2 may be formed or provided on inner surfaces of the enclosure component 10.
  • the component 10 After its prefabrication the component 10 is placed in a mould (not shown in Figures 1 and 2) the internal shape of which is the intended external shape of the finished unit. A cementitious mixture together with a measured quantity of water is introduced into the mould so as to form the body 11, which will be hydraulically and mechanically bonded (cemented) to the internal surfaces of the enclosure 10, providing an integral unit 10, 11 at least one face 18 of which is of a 'fair facing" material.
  • the cementitious mixture of the body 11 has suitable inclusions such as expanded polystyrene granules, expanded clay, fibreglass, exfoliated vermiculite and/or expanded perlite.
  • suitable inclusions such as expanded polystyrene granules, expanded clay, fibreglass, exfoliated vermiculite and/or expanded perlite.
  • Known technology for the production of aerated concrete may be exploited to ensure that, in addition to strength-imparting aggregates, the cementitious material contains air- or gas-filled voids to provide improved thermal insulation. For example 0.2 % by weight of aluminium powder may be included in the mixture. This will react with alkaline substances in the mixture to produce hydrogen bubbles before the mixture hardens.
  • a unit is provided with has load-bearing top 36 and bottom 37 surfaces, "facer” sides 38 and 39 and 'header' ends 40 and 41.
  • the external surfaces of the "sides" of the 'box' 10 are flush with the exposed surfaces of the body 11 to give a regular, rectangular contour.
  • FIG. 3 illustrates an annular enclosure 10 A made by moulding or e. g. by bending a strip of wet clay about three transverse lines and then joining the ends.
  • the enclosure component 10A is given a base 19 of the same material. If made of clay the constructed component 10 A may be fired in a kiln before being filled with a cementitious core 21 as shown in Figure 5. This Figure also shows that weep-holes 20 may be provided in the base 19 for the escape of surplus moisture from the cementitious core 21.
  • the choice of materials for the enclosure 10 A, with or without a base 19, and for the cementitious core 21, is as indicated in connection with the embodiment of Figures 1 and 2.
  • the prefabricated and hardened enclosure component 10 A is placed in a cast-iron mould 23 before the introduction of the cementitious mixture.
  • clay for the component 10 A it may be fired while in the mould 23, the mould being covered by a removable lid 24 having perforations 26.
  • the mould 23 may serve the secondary purpose of supporting the component 10 A while a cementitious core 21 is formed therein.
  • the core 21 is shown as a homogeneous body it may alternatively be constructed from mutually bonded, adjacent layers all of cementitious material but differing in their load-bearing and thermal insulation characteristics. Thus certain layers may provide the unit with the requisite load-bearing strength, being of a dense, high-aggregate mixture while one or more other layers may be reticulated or consist of a high proportion of air- or gas-filled voids.
  • any thermally insulating layer should be perpendicular to the direction in which the unit will face outward of a wall, in use.
  • Individual layers may be prefabricated separately, e. g. by moulding, before introduction into the enclosure 10 A or aftematively the interior of the enclosure 10 A may be sub-divided by removable partition means (not shown) and the cementitious mixtures introduced on opposite sides of the partitions.
  • the removable partition means may be physically removable before the wetted cementitious mixtures have hardened, allowing them to bond together, or degradable or porous membrane partition means may be used which, while serving to separate the dry mixtures when introduced so as generally to preserve the shape of the layers, will not prevent the wetted mixtures from bonding together.
  • FIGs 7 and 8 illustrate a further modification of the unit in accordance with the invention in which prefabricated thermal barrier elements 50 A and 50 B are positioned in the enclosure 10 A, and their end edges fixed to the end walls 40 and 41 of the enclosure 10 A, before cementitious material is introduced on opposite sides of each barrier element 50 A and 50 B.
  • each barrier element such as 50 A may itself be of cementitious material.
  • a base member 51 is made, for example by moulding, from an aerated cementitious mixture so as to have recesses 52 distributed throughout one face.
  • a membrane 53 is laid over this face and covered by another cementitious layer 54 so as to form a barrier element 50 A a high proportion of the interior of which is made up of voids because the membrane 52 has prevented the added layer 54 filling the recesses 52.
  • the barrier elements 50 A and 50 B are inserted into the enclosure component 10 A so that their opposite edges bond to the end walls 40 and 41.
  • both components 10 A and 50 A or 50 B are dry at this stage it may be necessary to use additional cement.
  • cementitious material is introduced on opposite sides of each barrier element 50 A and 50 B, as in the previous examples, to bond both to the barrier elements and to the interior surfaces of the enclosure 10 A.
  • the two barrier elements 50 A and 50 B would differ in the disposition along their lengths and/or breadths of the voids 52 therein so that, in a direction perpendicular to the sides 38 and 39 of the unit, no two voids of the respective barrier elements 50 A and 50 B would be in alignment.
  • Both the enclosure 10 A and the barrier elements 50 A and 50 B may be made of glass, e. g. by moulding, in which case the barrier elements 50 A and 50 B may be inserted in the enclosure 10 A while the glass is still hot so that the end edges of the barriers will fuse to the enclosure. After allowing the assembly to cool it is filled with a cementitous mixture, and in this case the mixture(s) may include suitable colourant(s).
  • larger units e. g. 150 mm x 215 mm
  • larger units may be provided for particular purposes, for example to build an external wall with a ceramic facing in a building of timberframe con. struction. In this case additional insulation between the studwork may be dispensed with if the units of the invention are given adequate thermal insulation properties.
