Definitions

  • the present invention relates to a light-weight wall element produced quickly and cheaply, and being particularly suitable for house building in warm countries such as in the Middle East.
  • Building elements can be produced either at building sites or in building element factories.
  • the external surface or face of this type of element is nowadays often made of porous, gypsum-based materials, timber or reinforced concrete. Thermal insulation and weather insulation of gypsum-based materials is often very poor, and wood cannot resist termites in warm countries. Elements being made of concrete and reinforced with steel are usually massive, thick and heavy, and transportation and erection costs for such elements are high.
  • the main object of the present invention is thus to provide a light-weight, prefabricated wall element particularly suitable for use in warm countries.
  • a further object of the present invention is to provide a light-weight wall element which can be manufactured quickly and at a low cost.
  • Still another object of the invention is to provide a method for manufacturing such elements.
  • Figure 1 is a cross-sectional view of a part of the element or unit of the present invention.
  • Figure 2 is a further cross-sectional view of the element of the invention, and particularly shows the edge detail, i.e. the L-shaped fixing profile.
  • Figure 3 is also a cross-sectional view of the invention, and especially shows one embodiment of the mechanical fixing of the reinforcement of the external layer.
  • Figure 1 shows a sandwich type construction of a wall element in accordance with the invention. Between an external concrete layer 8 and an inner board 3 there is positioned a thermal insulation 4.
  • Figures 2 and 3 show primarily the construction of the external layer.
  • a ribbed lathing 9 has been fixed using a joint comprising mechanical fixing means 10.
  • the lathing 9 is provided with ribs 12.
  • Figure 2 shows an L-shaped steel profile 7 surrounding the element.
  • the element of the present invention can be made for example using the following method:
  • the frame 2 of the element can be made of any suitable material, for example timber or steel. It is required that the frame 2 be rigid. In the shown embodiment of the present invention the frame 2 constitutes a load carrying construction and the concrete layer 8 stiffens the frame and can withstand wind loads.
  • the (perforated) ribbed lathing 9 (for example British red- rib) is used as a covering of the frame 2.
  • the lathing 9 is made of galvanized steel sheet and acts as a double- functional reinforcement; the ribs 12 act as tension bars and thus as a bracing construction, and the ribbed lathing 9 acts as a key for the concrete and reinforcement to avoid wreckage.
  • the concrete slab is thus reinforced in one direction.
  • Ribbed lathing 9 and L-shaped profile 7 are fixed directly to the frame 2 by fixing means capable of transferring forces.
  • the fixing can be made preferably mechanically, for example using hot dipped galvanized screws 10.
  • the fixing can be made for example using the tack welding method, in a line.
  • the concrete casting is made in the ordinary way onto the frame 2: the concrete is spread, vibrateduwith beam tamping and the surface is textured (e.g. by brushing).
  • Use of light-weight lathing or net 9 makes possible that the layer 8 need not be heavy; the concrete layer 8 is considerably thinner than normal, and moreover - because the concrete is fixed to the frame 2 with the reinforcement - the stiffening capacity of the concrete is utilized.
  • the wall element of the present invention can be moved to storage immediately after casting, whereas an element made using traditional methods has to dry in its mould for about twenty-four hours.
  • the suction casting method can be used when producing elements of the present invention, i.e. the excess amount of water will be sucked away.
  • the suction casting method cannot be used whenrproducing traditional sandwich elements.
  • the external layer of the element of this invention is thin, about 25 mm (when using the traditional techniques to produce elements the external layer is about 70 mm).
  • the total thickness of the element (2.4 x 2.6 m) of the present invention, described in the foregoing example, is only about 110 mm, of which the thermal insulating wool is about 70 mm, which satisfies the Middle Eastern standards.
  • the bulk density of the element is thus 500 kg per cubic metre, which is only about 16 per cent of the bulk density of the traditional sandwich element, and the element is thus very light and economical to move and transport.
  • the element of the present invention is, however, firm and durable, and its thermal insulating capacity is good. The element has been calculated for 100 kg/m 2 wind load.
  • the production of the element of the present invention does not require great hall areas, neither expensive moulds nor heavy equipment for moving elements on the production area or at the building site.
  • the casting site does not require great investments, and the making of the element does not require highly skilled workers.
  • the element can be produced in small workshops quickly, and at low material ' and labour costs.
  • the fact that the element can be moved to storage immediately after casting, enables a large production capacity.
  • Light equipment like forklifts is sufficient to move the elements of the present invention. The lightness of the element therefore saves on handling equipment and shortens erection time, and makes possible the use of lighter foundations.
  • the element of the present invention can be made coloured in a cheaper way than traditional elements.
  • the element of the invention needs significantly less concrete, and therefore it needs less colour powder, too, which generally has been added about 6 per cent of the weight of concrete; in other words, three times more colour powder . is neede to colour the traditional sandwich element than to colour the element of the present invention.
  • the wall element, and method of producing same can be modified within the scope of the claimed invention, and in accordance with prevailing working conditions.
  • the elements of the present invention are provided mainly for the demands of warm countries, they can be suitably modified for use under cooler conditions, too.
  • the thickness of the rock wool layer could be increased, or the layer can be replaced by polyurethane foam for the sake of increasing the thermal insulating capacity.
  • the main advantage of the present invention is that there is a concrete slab constituting the external layer of the element, and this slab is made by using the frame as a mould, and furthermore it is reinforced with the ribbed steel lathing which is affixed directly to the frame, preferably mechanically.
