Description

The invention relates to construction and can be used for wall and roof fencing of buildings of industrial and civil construction.

Known building panel containing the upper and lower cladding, made in the form of a sheet or corrugation and equipped with additional sheets made of perforated, and a heater made of foamed polymer composition placed between the cladding, while the perforated sheets are located on the inside of the panel under the cladding [1].

Also known is a construction panel comprising an outer shell, an inner profiled sheathing, a heater located between the outer sheath and the inner profiled sheathing, a flat diaphragm located on the inside of the profiled sheathing [2].

The closest analogue to the claimed building panel is a building panel comprising an outer cladding, an internal profiled sheathing, a heater located between the outer cladding and the inner profiled sheathing, a flat diaphragm that is discretely attached by fastening ties to the profiled inner sheathing from the outside, while the thickness is flat the aperture is 1-30 mm [3].

A disadvantage of the known building panels is low fire resistance and insufficient rigidity and structural strength of the panel.

The technical result that is achieved by the implementation of this invention is to increase the degree of fire resistance and bearing capacity of the building panel by increasing the rigidity and strength of the construction panel.

The specified technical result is achieved by the fact that the building panel containing the outer cladding, the inner profiled sheathing, a heater located between the outer cladding and the inner profiled sheathing, a flat diaphragm attached by fixing ties to the profiled inner sheathing from the outside, is provided with a gasket through which the flat diaphragm attached to the profiled inner lining, and the outer lining is glued to a rigid substrate.

The thickness of the flat diaphragm together with the gasket is at least 30 mm.

According to the invention, the gasket can be made of structural material in the form of strips located in places in which the panel is supported by supporting structures.

According to the invention, the insulation is made of foam, or glass wool, or basalt wool, or in the form of glass granules, or in the form of phosphate granules, or from sand dune.

In addition, the rigid substrate is made of drywall, or of wood fiber boards, or of plywood, or of metal, or of paper, or of asbestos cement, or of phosphostekloplastik.

According to the invention, the outer lining is made of roofing material, or of chlorosulfopolyethylene, or deposited bitumen materials, or of fiberglass and fiberglass mesh with water-resistant bonds, or of waterproof films.

According to the invention, the insulation layer adjacent to the rigid substrate is reinforced with bulk filaments and fibers in the form of a mat of glass, or basalt, or graphite, or metal.

In addition, in the construction panel, on the protruding parts of the inner profiled sheathing, side bends of 20-30 mm wide and 30-80 mm long are made on the side of the transverse edges.

In the rigid substrate according to the invention, grooves are made on the surfaces of the protruding parts of the inner profiled sheathing, while the cut off sheathing parts are bent to a height of 20-30 mm

According to the invention, slots can be made in the rigid substrate through which a flexible thin tape is passed, and the slots can be made in any part of the surface of the rigid substrate.

In addition, the ends of the flexible thin tape can be connected with the specified bends of the internal profiled sheathing.

According to the invention, a flexible thin tape can be passed through a layer of insulation at any distance along its thickness.

The ends of the flexible thin tape passed through the foam layer can be fastened to form a loop, or they can be attached to the longitudinal edges of the profiled inner sheathing.

Figure 1 shows the construction panel in section.

Figure 2 - design of the internal profiled sheathing.

Figure 3 - gasket design.

Figure 4 is an option for mounting a flexible thin tape.

The building panel contains an outer lining 1 (Fig. 1) glued to a rigid substrate 2, an inner profiled sheath 3, a flat diaphragm 4, which is discretely attached using fastening connections 5 to a profiled inner sheath 3 from the outside through the gasket 6. Between the outer lining and internal profiled sheathing is located insulation 7.

The thickness of the flat diaphragm 4 together with the gasket is at least 30 mm, while the thickness of the flat diaphragm 4 is 1-20 mm, and the thickness of the gasket is 10-30 mm.

According to the invention, the gasket is made of structural material in the form of strips 15 (Fig. 3) located in places in which the panel is supported by supporting structures.

The insulation 7 can be made in the form of foam, or glass wool, or basalt wool, or glass granules, or phosphate granules. As insulation, sand dune can also be used.

There are various options for using the materials from which the rigid substrate 2 is made. The rigid substrate 2 can be made of drywall, or of fiberboard, or of plywood, or of metal, or of paper, or of asbestos-cement, or of phosphostekloplastik.

The outer lining 1 can be made of roofing material, or of chlorosulfopolyethylene, or deposited bitumen materials, or of fiberglass and fiberglass mesh with water-resistant bonds, or of polyvinyl chloride films, or of metal, or of waterproof films.

According to one embodiment of the invention, when performing the insulation from foam, its layer adjacent to the rigid substrate 2 is reinforced with bulk threads and fibers in the form of a mat 8, 9 made of glass, or basalt, or graphite, or metal.

In addition, in the construction panel on the protruding parts of the surface of the inner profiled sheathing 3 from the side of the transverse edges, bends 10 with a width of 20-30 mm and a length of 30-80 mm can be made (FIG. 2).

In the profiled sheathing 3 according to the invention, notches 11 can be made, while the cut-out parts of the sheathing are bent to a height of 20-30 mm.

According to the invention, slots 12 can be made in the rigid substrate 2, through which a flexible thin tape 13 is connected, connected to the bends 10 on the inner profiled sheathing, and the slots 12 can be made in any part of the surface of the rigid substrate 2.

According to the invention, the flexible tape 13 can pass through the layer of insulation 7 at any distance along its thickness, forming a closed loop (figure 4).

The ends of the flexible thin tape 14 can be connected with the bends 10 of the internal profiled sheathing 3.

The panel is made as follows.

Mount the shell of the panel - the outer lining 1 with a rigid substrate 2, for example, from a film and a fiberboard, into which the flexible tape 13 is previously passed (Fig. 3). The assembled element is laid on the bottom of the forming installation. Then, an activated composition consisting of a resin, a hardener and an active finely divided additive is poured onto it. If necessary, then lay mats 8. Then lay the profiled inner lining 3, made, for example, of corrugated metal sheet, which is connected, for example, by means of a flexible tape passed through slots made in a rigid substrate 2, with bends 10 of the inner profiled lining 3 Preliminarily, fiberglass mats 9 are laid on the corrugated metal sheet from the outside and, through a gasket 6, are discretely attached, for example, with self-tapping screws, to a flat diaphragm 4 made For example, plasterboard. In the process of foaming, the liquid activated composition passes through openings formed as a result of bending the edges of the protruding parts of the surface of the inner profiled sheath 3 and the cuts 11, filling the internal cavities both between the outer lining and between the diaphragm. When foaming, the liquid activated composition also penetrates the fiber mats or pre-filled granules. After curing the foam, the panel is ready for use. The thickness of the diaphragm with the gasket is at least 30 mm.

The use of the construction panel allows to increase fire resistance and load-bearing ability, as the profiled sheet is protected from fire.
