DESCRIPTION:
BRIEF SUMMARY
The invention relates to a wall construction comprising supporting poles and filling material cast between them.
Further, the invention relates to a method of manufacturing a wall construction, in which method supporting poles are mounted in place, a mould is mounted in such a way that the supporting poles remain inside the mould and filling material is cast inside the mould between the supporting poles.
It is known to build different wall constructions, but the problem often is that manufacturing a wall construction is complicated, laborious and slow and thus expensive. On the other hand, many insulations used for wall constructions cause problems with fire safety.
Finnish Publication 75 389 discloses a wall frame consisting of lightweight beams and foam concrete used as surface and filling material between the beams. The wall is made in such a way that a casting mould is fastened on the lightweight beams and the foam concrete is sprayed inside the casting mould. For the construction of the wall are required separate heavy and expensive moulds, due to which the wall is slow and expensive to manufacture.
German Offenlegungsschrift 42 15 081 discloses a clay wall element and a method of manufacturing it. The element comprises supports and a filling of light-weight clay and also notches and pins for attaching an element to other elements. The element is cast inside separate moulds, due to which the wall is difficult and expensive to manufacture.
British Patent 1 599 033 discloses a wall construction comprising studs, to which are fastened plasterboards. Further, porous plastics foam is cast between the plasterboards. However, the total costs of such a wall construction are high.
German Offenlegungsschrift 39 21 881 discloses a prefabricated wall element of wood. There are wooden parts both outside and inside the element in question and concrete shall be cast between them either in advance or on construction site. The material costs of such a wooden wall element are high and the element is slow and difficult to manufacture.
Finnish Publication 932 441 discloses an insulated wall of a wooden house. This wall comprises an outer layer of wood and between the outer and the inner layer an insulation consisting of mortar layers and layers of rammed chips. Such a wall has high material costs and is slow and complicated to manufacture.
An object of the present invention is to provide a wall construction, which is simple and stable and has a favourable price.
A further object of the invention is to provide a method of manufacturing a wall construction, by which method the wall construction can be made quickly and advantageously.
The wall construction according to the invention is characterized in that the wall construction comprises a close-meshed metal net attached at least to one side of the supporting poles, the metal net forming part of the wall construction and together with the filling material a reinforcement.
The method according to the invention is characterized in that a close-meshed metal net is attached at least to one side of the supporting poles, which net forms part of the mould, and that boards are attached at spaced intervals outside the metal net to support it, whereby the metal net acting as a mould forms part of the wall construction and together with the filling material a reinforcement.
The essential idea of the invention is that a close-meshed metal net forming part of the mould is attached to the supporting poles and boards are attached at spaced intervals outside the metal net. Subsequently, filling material is cast into spaces formed by the metal net and the supporting poles, whereby the net acting as a mould forms part of the wall construction and together with the filling material a reinforcement. Further, the idea of an embodiment is that a mixture of lightweight aggregate and concrete is used as filling material.
The advantage of the invention is that a wall construction made by the method is fire safe, quick to manufacture and simple and has a stable structure and a favourable price.
