Description

WALL CONSTRUCTION AND METHOD FOR MANUFACTURING A WALL CONSTRUCTION The invention relates to a wall construction comprising support posts and molded filler material therebetween. Furthermore, the invention relates to a method for lubricating a wall construction, method in which the support posts will be installed in place, a mold is installed in such a way that the posts remain therein and filling material is arranged inside the mold between the support posts. The technique of making different wall constructions is known, but the problem is often that the manufacture of a wall construction is complicated, laborious and slow and, therefore, expensive. On the other hand, many insulating linings used for wall constructions cause fire safety problems. Finnish Publication 75 389 describes a wall structure consisting of light beams and foam concrete used as a surface material and as a filler between the beams. The wall is made in such a way that the molding die is fastened to the light beams and the foam concrete is fed into the molding die. For the construction of the wall heavy and expensive molds are required, due to which the manufacture of the wall is slow and expensive. The German Offenlegungsschrift 43 15 081 describes a clay wall element and a method for manufacturing it. The element comprises supports and the filling of light clay also notches and tenons to join one element with another. The element is molded in separate molds, due to which the manufacture of the wall is difficult and expensive. British Patent 1 599 033 discloses a wall construction comprising uprights to which plasterboard is fastened. However, the total cost of that type of wall is high. The German Offenlegungsschrift 39 21 881 describes a prefabricated wooden wall element. There are wooden parts both inside and outside the element in question and concrete is molded between them either in advance or at the construction site. The material costs of this type of wooden wall element are high and the manufacture of the element is slow and cumbersome. Finnish Publication 932 441 describes an isolated wall of a wooden house. This wall comprises an external layer of wood and, between the inner and outer layers, an insulating lining consisting of layers of mortar and layers of tamped chips. This type of wall has high material costs and its manufacture is slow and complicated. An object of the present invention is to produce a simple and stable wall construction at a favorable price. Another object of the present invention is to present a method for manufacturing a wall construction, by which method the construction can be carried out quickly and advantageously. The wall construction according to the invention is characterized in that it comprises a very fine mesh metal net adhered to at least one side of the support posts, this metallic net of the wall construction being part of and constituting a reinforcement together with the Filling material. The method according to the invention is characterized in that it has a fine-mesh metal net adhered to at least one side of the support posts, a network that forms part of the mold and the boards are adhered at spaced intervals outside the metal network to to hold it, whereby the metal net acting as a mold forms part of the wall construction and, together with the filling material, constitutes a reinforcement. The essential idea of the invention is that a thin mesh metal network forming part of the mold is adhered to the support posts and the boards are fixed at spaced intervals outside it. Next, filler material is put into the spaces formed by the metal net and the support posts, whereby the network acting as a mold is part of the wall construction and, together with the filling material, constitutes a filling. In addition, the idea of an embodiment is to use a mixture of lightweight aggregate and concrete as a filler material. The advantage of the invention is that a wall construction manufactured by this method is fire-safe, quick and easy to manufacture and has a stable structure and a favorable price. The invention is described in greater detail in the accompanying drawings, in which Figure 1 illustrates a wall construction according to the invention partially and axonometrically in cross section. Figure 2 illustrates the wall construction of Figure 1 from above and Figure 3 illustrates another wall construction according to the invention from above. Figure 1 illustrates a wall construction according to the invention. To carry out the wall construction, the support posts 1 are erected first. The support posts 1 preferably consist of impregnated wood and are held in place in their future position. The wooden support posts 1 constitute the main support structure of the load. By using wooden support posts 1, the manufacture of a wall construction is simple, fast and advantageous. A fine mesh metal net 2 is adhered to both sides of the support posts 1. The term "fine mesh" means, in this context, that the wires of the metal net 2 are so close to each other that the filling material that is intended to be used for the wall construction can not flow substantially through the network. metallic 2. The metal net 2 is fastened to the wooden support posts 1 in a simple and very fast manner, for example by means of rapas, small hooks, small nails or the like. The metallic net 3 may comprise several network parts placed adjacent to each other in such a way that they partially overlap each other. The metal nets 2 are supported on the opposite side of the support posts 1 by means of boards at spaced intervals. The term "at spaced intervals" means in this context that the adjacent tables 3 are not interconnected but are placed at intervals such that the metal nets 2 can not substantially when the filling material is inserted between them. Since the metal net is supported during molding by the outer sheathing, the wire of the metal net does not need to be very thick, due to which, for example, woven wire for poultry houses can be used as a metallic net 2. After In this case, the suitable filler material is mixed for the wall construction consisting, for example, of light concrete aggregate, and the mixture 4 in question is arranged between the metal networks 2 in such a way as to fill the space between the supporting posts 1. and that remains fixedly attached to them. The filler material can also be a mixture of, for example, blast furnace slag or some other material or and concrete or some other material having a low specific weight. However, mixture 4, of light aggregate concrete is advantageous, as far as the price and the properties of insulation and fire safety are concerned. Once the mixture 4 has solidified, the sheathing can be suppressed, if desired, or left in place for a possible decorative coating. To improve the adhesion between the support posts 1 and the mixture 4, the support posts 1 may comprise, for example, according to the constructions, holes 5 or fastening elements such as nails 6 or the like nailed, for example, to the posts of wood If desired, a finished wall construction can be coated, for example, with a plaster 7 or other similar material. On the support posts 1, a horizontal wooden crossbar can be attached, to which, for example, the ceiling support beams can be attached. On the other hand, metallic net 2 acts as reinforcement andIn addition, as a molding matrix and in a finished wall construction, as a support corresponding to the concrete reinforcement and firmly adhered to the filling material. Consequently, the wall construction can act as a miscalled load-bearing wall construction. Figure 2 illustrates the wall construction of Figure 1 from a top plane. The reference numerals of Figure 2 correspond to the reference numerals of Figure 1 The metallic nets 2 are directly fastened to the surface of the supporting posts 1, due to which there is almost no mixture 4 of light aggregate and concrete in the external surfaces of the support posts 1. Figure 3 illustrates another embodiment of the wall construction according to the invention. The reference pointers of Figure 3 correspond to the reference numerals of Figures 1 and 2. In the wall construction according to Figure 3, the metal nets are attached to the support poles by means of supports 8. supporting posts 1 are then on all their sides substantially within the mixture of aggregate and concrete to be molded. Thus, an uncoated wall construction of substantially uniform appearance is produced, in which only the ends of the supports 8 are visible. In the cases illustrated in Figure and Figure 3, the wooden support posts 1 are especially useful as nailing strips, which can be used for easy clamping of a possible external and internal cladding of the wall construction. The drawing and the description attached thereto are only intended to illustrate the idea of the invention. As for the details, the invention may vary within the scope thereof. So that the method and the wall construction according to the invention can be used, for example, to repair old buildings in such a way that the supporting posts 1 are installed on an old wall and outside them a metal network 2 and a deck. Next, filler material is placed, for example a mixture 4 of light aggregate and concrete, between the old wall and the metal net 2 and the boarding.
