The invention relates to the construction, namely, the building materials industry, in particular to a multilayer wall stones used in the construction of civil and industrial buildings, such as houses, cottages and other buildings.

Known technical solution copyright certificate №983219, class E 04 1/00, 1979, "a Method of making wall blocks", in which production units produce group method, perform pre-monolithic wall of aerated concrete, and then cut it into large separate building blocks. However, the proposed method is time consuming, as is the operation of cutting the monolithic walls into separate blocks, which requires additional equipment.

Known technical solution according to the patent No. 2166037 "Building element and tooling for its manufacture", class E 04 1/40, 2000, which describes the construction element and method of manufacture, which consists in the fact that in the manufacture of multilayer construction element pre-made one of the layers, using a cuvette with vibration solution, completing this cell, give the necessary exposure that layer, and then using it as formwork, put on his metal shell, insert it either punches or liners shall fill the whole form solution, subjected to vibrations, set for natural drying to full readiness of the construction element. However, the described technology and technological equipment is very complex, time-consuming, inefficient, so as to produce consistently only one construction element.

Known technical solutions in the construction of buildings and structures use non-removable formwork, representing, for example, of hollow construction element made of concrete, see patent No. 2074296, class E 04 1/00,1993, voids which in the construction of walls are either filled with heavy concrete or insulating material, or structural concrete. In the technical solution according to the patent No. 2158338, class E 04 2/26,1999 also used a permanent formwork, but only made out of fabric-reinforced, multi-layer plaster, and an internal cavity filled with filler coated with glue, after which the whole multilayer dry element, one side of the line and finish. However, this technology is also very difficult, time consuming and costly as material and frame elements.

Known technical solution according to the patent No. 2199637, class E 04 2/06, 2001, "Method of manufacturing slabs of permanent formwork and slab permanent form", which is in the form of post-rod valve,is placed a layer of hard concrete mix, set fibromastopathy, stack the top layer of concrete mixtures by vibroplate produce a casing, heat treatment, cutting the ends of the valve and removing the plate from the tray. Thus obtained permanent formwork is used to place on the site where it is applied concrete mixes, which are void and are concatenated with the shuttering plate. However, this method of manufacture of building elements is time-consuming and not suitable for the manufacture of various building blocks and wall stones.

The technical task of the present invention is to provide such a wall of concrete layered stone and method of its production, where possible joint use of different raw building materials, with obtaining protective surface layer in the monolithic product, as well as reducing the complexity forming operations and raw materials for its production, increasing productivity and lowering the cost of the unit and its manufacture.

The technical result that can be obtained by using the proposed technical solution is to simplify the technology of permanent formwork, the use of a continuous cycle of production of multilayer stone wall at low his sebastain the property.

This object is achieved in that the multilayer wall rock consists of several vertical layers, the outer of which is made of building sand, concrete, formed either by making or vibratory casting with the initial crystallization, and is used as permanent formwork for forming the next adjacent layer, made either of aerated concrete or concrete light-weight fillers. Multilayer wall stone is characterized by the fact that the outer layer is a permanent formwork can be made of concrete, light-weight filler, and the content of light fillers in it does not exceed the number of fillers in the subsequent adjacent to a fixed timbering subsequent layers. The task is part of the method is achieved by the fact that it involves the formation of a permanent formwork by installing a closed outer shape, the sides of which are made with vertical slots on the tray or other flat surface, and then placed symmetrically inside her like her inner box, the sides of which is provided with vertical slits corresponding to the slits form, fixed relative to each other in shape and insert vertical elements that are installed in the slots, fill the space between the insert and the form of construction is entrusted sandy concrete, manalicious it by pressing either the vibratory casting, then remove the form, insert and vertical elements, to form cells within the newly created permanent formwork placing the separation of the interconnected walls, the free ends of which are fixed in the slots of the parties to the retained formwork, obtained from the vertical elements, and then make the fill of a cell or cellular concrete, or concrete with light fillers in the form of polystyrene, expanded clay, sawdust, ash, aged, dried, remove the partition, get ready multilayer wall stone, sent to the stacking. This object is achieved in that the separating partitions perform with vertical slots, equal in height at least half height partitions and width not less than the thickness of the walls, and the height of periodoc equal to the height of the form. This object is achieved in that the outer form, insert and vertical elements can be made as a single unit, for example welded.

Figure 1 shows the form and the insert with a vertical locking elements, figure 2 - the process of filling of the cells formed in the fixed casing, figure 3 - embodiments of the cubicles, in Fig. 4 - ways multi-layered stone wall.

Multilayer Lenovo the stone produce way consisting in the following. Mounted on the pallet or on any flat surface such as the floor of the shop, the outer form 1, representing a closed geometric figure with vertical walls 2, the height of which is chosen equal to the height of the stone wall, and walls made 2 vertical slits 3, the distance between which is chosen equal to the length of the stone wall. In this form placed symmetrically similar to the form 1 inner box 4 with vertical walls 5, which is equal to the height of the walls 2 form 1 and which also made the slots 6 located opposite the slots 3. In slots 3, 6 are inserted into the connecting vertical locking elements 7, which perform two functions: record form 1 and box 4 relative to each other and simultaneously divide the internal space formed by the form and pasting it on a separate partition 8. To reduce the complexity of Assembly of the outer form 1, the inner insert 4 and vertical elements 7, they can be executed as a single unit, for example made of welded. Section 8 can either be D-shaped, or linear, or any other depending on the configuration of the form 1, (e.g., circle, polygon etc). Section 8 fill or sand, concrete, or other building with concrete filler, and then subjected to a flooded section vibro is escolania, but you can fill sections 8 vibratory casting, which leads to monolithic whole structure. After the initial crystallization of the concrete mix in sections 8 delete a form 1, box 4 and connecting the locking elements 7, receiving a fixed casing 9, which is used in the future as a layer of building stone and as formwork for obtaining multilayer stone wall. When making use of the form is removed after the primary crystallization of the concrete mix, and the application of vibratory casting form is removed after partial solidification of the concrete mix. The use of a single weldment outer forms 1, the inner insert 4 and vertical elements 7 to obtain permanent formwork significantly reduces the time of the preparatory work and increases the productivity of manufacturing multilayer stone wall. In the gaps between the sections 8, at the location of the elements 7, insert the metal walls 10,11 and fix their retainers 12, thereby forming the internal cell 13 inside the casing 9, in which either one or two sides are elements of permanent formwork made of concrete. Deleted form 1, the insert 4 and the elements 7 is again used, which ensures the continuity of the process without unnecessary stops. Metal partitions are made either of prodol who scored 10, or transversal 11, wherein the longitudinal partition 10 in length equal to the length of the form 1, and transverse 11 equal to the width of the form 1. In the longitudinal walls 10 made of vertical slots 14, the distance between which corresponds to the slits 3 in the walls of the mold 1, and the transverse partitions 11 are also made of vertical slots 15, and if the slot 14 is made from the bottom to a height of not less than half the height of the walls, the slits 15 are made from above to a height of not less than half the height of a partition, and width of all slots equal to not less than the thickness of the walls, see figure 3, 4. After installation of partitions 10, 11 formed cell 13 is filled or foamed concrete, or concrete with light fillers, such as polystyrene, expanded clay, sawdust, ash. After the executed works flooded cell 13 can withstand, dried, remove the partition 10,11, get ready multilayer wall stone, which is sent to the stack.

Received stone wall 16 is a double-layered product, one layer of which 9 are made of solid concrete mixture, is used as a permanent formwork, as well as the layer 9 is used only for initial crystallization of concrete, while its further use as formwork, i.e. the interaction with subsequent poured concrete forming PEFC is blowing layer 17, is durable adhesion of one layer to another, which ensures a good, reliable connection educated. In the manufacture of stone can be used not only 4-wire form, as shown in figure 1, and with a large number of cells 13, thus should be used in the partition 10, as shown in figure 4, with multiple slits 14. In this case, get a stone wall 16 not only with an angular casing, see figure 5, a and stone wall 18, see Fig.6, where the retained formwork is only on one side of the stone. In the manufacture of permanent formwork may use the same type of concrete mixtures used for the subsequent adjacent layers on both quantitative composition of light fillers, and density. However, the number of light fillers in a fixed timbering should not exceed the number of light fillers in subsequent adjacent layers. When using cellular concrete density of permanent formwork must not be lower than the density of the next adjacent layers. Such usage is also greatly simplifies the manufacture of the multilayer wall of stone. The use of metal molds 1 and metal partitions 10, 11 provides a flat, smooth side surfaces of the stone, and the use of pressing or vibratory casting excl which includes the possibility of voids and sink inside the stone that also greatly increases the strength properties of the stone, and also allows you to reduce the cost of the stone through the use of permanent formwork, which is one of the layers of building stone.
