The invention relates to the construction industry, in particular for the production and use in the construction of one of the types of formwork is fixed to the formwork with the facing outer surfaces of the plates, e.g. made from natural fiber materials, synthetic resin-bonded chipboard, intended for use in monolithic construction.

Known wall construction (see the patent for useful model of the Russian Federation No. 20112, 18.05.2011,, IPC EV 1/00) for buildings frame-monolithic type, containing supporting frame formed of vertical and horizontal frame elements, fastened together at their intersections, with duplex shell-casing, the inner space of which is filled with filler. In this device the vertical frame elements made in the form of racks from a single or dual curved profile, for example, Z-shaped, made of galvanized steel. Profile shape may be slightly different when used in outer walls, at the intersection of walls, door and window openings. Hours of dual profile, forming a cellular structure, attached to the horizontal frame elements and used as a leave formwork. This wall structure may be used for buildings of frame-monolithic in the de removable casing, and foam, used as filler, after removal of the removable casing is subjected to processing materials. The disadvantages of this design should include the complexity of the technological process of preparation and formwork at construction site, as well as the intensity of the connecting structural elements of the skin.

Known permanent formwork containing outer plate and the inner plate of the casing, connected with the formation of internal volume to fill a building material (see patent for useful model RF # 44717, IPC E04G 9/04, E04G 11/00, 27.03.2005, a known non-removable formwork slabs of cement-bonded particleboard. During the construction of the walls of the plate is pre-fixed to wooden frames, which are fastened to each other by bolts, which complicates the installation of the walls and increases the time of the meeting. In addition, the concrete mix can act on the front surface of the walls and joints in the joints of the formwork and therefore requires additional cleaning, which complicates and increases the cost of construction and facade in this case requires additional decorative facing, which should be attributed to the shortcomings of this type of formwork.

The use of key elements for the connection of external surfaces allows to simplify the process of erection of monolithic walls of buildings and to reduce the time for installation. One example of such a technical solution is provided below.

A device coupler (see RF patent 2306391, 10.04.2007,, IPC EV 2/00) for a fixed casing during the creation of the construction of walls, foundations, by filling with concrete permanent formwork, which becomes part of the structure. A distinctive feature of this invention is to provide a screed for a fixed casing, which has a cross jumper with transverse grooves for installation of the valve. On each of the boundary parts of the jumper has to end with two spaced apart plates, perpendicular to the axis of the jumper and the United screed end. One of the perpendicular plate of each end is the end. Each end has at least one hole in the end plate, followed by stretching of the end parallel to the longitudinal axis of the bridge. The jumper is made in the form of a plate extending in the direction of the limit switches with the formation of the ribs.

This construction of the castle, like many similar devices used in prefabricated formwork removable type, has a significant drawback. The installation of these locks to be mostly on the perimeter of the facing plates, which imposes requirements as to apply the outer plates fixed aupaluk is, this provision of the necessary rigidity of the plates, which is associated with the choice of material, thickness and scope of the facing plates. Failure to comply with these requirements leads to the loss of the dimension of the cavity between the plates when you fill it with filler (concrete), because the elastic elements are arranged around the perimeter of the casing and are absent in the Central zone.

A device fixed construction formwork, which is designed for monolithic construction, and is made with a facing outer plates of various process materials or provided with outer decorative items left on site after filling the cavity of the casing filler.

The technical result is achieved due to the fact that a permanent formwork made of facing plates, interconnected by means of jumpers equipped with locking devices, and which are evenly placed on the inner surfaces of the plates. This design formwork allows secure attachment of the facing plates and saving settings tile cavity in the concrete pouring and other fillers. In this formwork can be used as the facing plates of various materials, including thin metal sheets, polymer, composite, chipboard, when the use of the implement plates with high surface quality is still a question of carrying out wet finishing of the surfaces inside the premises and outside. You can also use decorative elements to the outer surfaces of the plates, which will not require additional finishing. Design features such formwork contain prerequisites for optimization of technological process of manufacturing of parts, formwork, equipment necessary filling (steel wire mesh, electrical and plumbing) in the factory and to be fully prepared for installation on the construction site under the filling liquid filling (light and heavy concrete, plaster solution and so on). Able manufacturing and Assembly of the panels in the factory mass production using a wide mechanization and automation of manufacturing processes and the reduction of the finishing work on the construction site eventually leads to the reduction in construction time.

The design of the claimed fixed constructional forms shown on the following drawings.

figure 2 - bracket-tie panels;

figure 3 - layout of the brackets on the stove.

Permanent formwork (figure 1) contains the outer plate 1 and the inner plate 2 secured to each other via n - jumpers at a certain distance from each other with the formation of the inner volume of the installation is rmatory and fill construction material, for example concrete. Jumpers consist of two interconnected using suzanah devices symmetrical brackets 3 and 4. The bracket is made of sheet steel with a thickness of 3-5 mm, and each pair of them is fixed to the inner surfaces of the facing plates 1 and 2 opposite to each other. The mounting bracket on the plates carried by the fastener, which in shelf brackets there are 4-5 units of technological holes 5 with a diameter of 6-8 mm End part of the bracket is made in the form of a 4-way hooks that the Assembly of the formwork are in mutual engagement and provide a solid connection of adjacent brackets, forming bridges between the plates 1 and 2. End part of the catches are made in two types, some of which are in the tail have a stepped platform 6, which by means of the punch is formed zasanie teeth 7 and restrictive lugs 8 in the form of protrusions, and other zasanie bands have reciprocal rectangular box 9 under appropriate zasanie teeth 7, the height of the stairs sites 6 corresponds to the thickness of the metal brackets. For right call and splicing of the brackets 3 and 4 stripes satanum tooth 7 is made in the tail otbortovku 10 width 5-7 mm, bent at 8-10° from the plane of the platform 6 in the opposite direction from the tooth, and the tooth has the shape of semi-circle. The approximate scheme is and the placement of jumpers on the plates 1 and 2 of the casing shown in figure 3. The number of straps is determined by the dimensions and configuration of the plates 1 and 2 taking into account the factors ensuring the rigidity of the fastening them before pouring the filler. The distance between the plates is ensured by the length of the jumper as the total length of the engagement between the brackets 3 and 4.

Manufacture and Assembly of permanent formwork as follows. On pre-prepared plates 1 and 2 on the layout are attached to the brackets 3 and 4, so that when the connection plates in the casing teeth 7 suzanah strips of the same species engages with catching stripes of another kind, with rectangular Windows 9. Mounting bracket to the plates is carried out by means of fasteners, such as screws-self-tapping screws through the holes 5 made in the shelf brackets. After that, the plate pairs arrive on the Assembly bench, where they are mounted provided in the technical documentation of the necessary equipment (valves, electrical cables, plumbing, etc..). Final Assembly of the formwork is made by connection plates 1 and 2 in the finished casing. The connection takes place with a continuous movement of one of the plates towards the other, in which zasanie teeth 7 are in engagement with the strips having a rectangular window 9, and is fixed by latching the speaker of the tooth in the box related the second bracket. The 8 stops serve to limit the stroke

suzanah strips during Assembly. Thus, the plates 1 and 2 form a complete casing, in which n-jumpers between the plates 1 and 2 provide the required parameters tile distance to the stiffness of the fixing evenly on the entire surface of the plates.

The effectiveness of the present invention is confirmed by the experience of manufacturing of such formwork industrially and used in the construction of residential buildings of monolith type. Such casings are made of large interior wall panels, exterior wall panels with window and balcony openings. If necessary, this method can be made formwork small size, for example 1×1.6 m, of which before pouring the filling method is simple constructor typed wall panels of different shapes and sizes. Selection jumper length allows to produce panels of different thickness, and the use of panels of different materials to meet the needs of customers, the decorative exterior and interior. From an economic point of view the method used in the construction of monolithic construction ready retained formwork reduces the time of construction of the wall several times.
