Description

The utility model relates to armored structures for protecting walls and roofs of buildings and structures from small arms bullets during operation in macroclimatic regions with a temperate and cold climate.

The protective panel is a box-section construction made of sheet steel, a system of internal steel screeds and anchors filled with heavy concrete of a special composition.

Known layered armored panels based on cement: a description of the invention to the patent of the Russian Federation No. 2487219, IPC E04C 2/26, F41H 5/04; publ. 07/10/2013. The fiber-reinforced cementitious armor panel includes a cement core comprising a continuous phase obtained by curing an aqueous mixture, a self-leveling agent based on polycarboxylate and water, and a coating layer attached to the surface of the cured continuous phase. Also known is a cement based armored panel system: description of the invention to the patent of the Russian Federation No. 2491493, IPC F41H 5/04; publ. 08/27/2013. The armored panel system includes a frame with an explosion-proof cemented armored panel mounted on it. Cement armored panels have a cement core with a continuous phase. The continuous phase is obtained by curing an aqueous mixture consisting of an inorganic cement binder, inorganic mineral filler, pozzolanic mineral filler, self-leveling agent and water. The armored panel can be reinforced with a top layer attached to one of the surfaces of the continuous phase.

The disadvantages of these developments include the need to use additional metal structures (frames) to place panels, the absence of sling elements, which complicates the installation process, and the limited purpose is only for protecting walls.

For the closest analogue, the device is adopted - Fencing panel: description of the invention to the patent of the Russian Federation No. 2267591, IPC E05G 1/024; publ. 01/10/2006. The device includes a metal wall and a reinforcing cage associated with it at many points. The reinforcing cage contains two longitudinal rods extending along the entire length of the panel and placed in the corners of the panel from the inside, and nodes formed by each of the four short rods and placed along the length of the panel with a constant pitch. Its disadvantages include the limited overall dimensions of the panels from 300 to 2500 mm long and 200 to 300 mm wide (high), low seismic stability of the structure and low bullet resistance of the panels (two classes below the proposed design - devices).

The technical task of this device is to use in the construction of an external protective structure of industrial buildings and structures of large area, not requiring additional (intermediate) load-bearing or spacer elements in the building structure, except for the main half-timbered elements: columns with T-shaped elements and runs with “] L” -shaped profiles; ensuring the mobility of the protective structure of the building during temperature, shrinkage and seismic deformations due to the fact that the panels are not fixed rigidly to the supporting frame.

The problem is solved by the design of the protective panel, with weight and size characteristics: length - from 500 to 6000 mm; height - from 200 to 1000 mm; thickness - 68 mm and specific gravity of 240 kg / m ² , which does not require welding of the panel joints between themselves during their installation, ease of removal of the protective structure without breaking the supporting frame during the demilitarization of buildings and structures.

The essence of the utility model is disclosed in examples of its implementation with reference to the accompanying drawings, which show the following:

FIG. 1 - General view of the protective panel with the image of the front (outer) side (side of a possible attack) and the back (inner) side.

FIG. 2 - System of internal steel ties and anchors: a) left view; b) general view, the front wall is transparent.

FIG. 3 - Panel protective execution ПЗщ-н.

FIG. 4 - Panel protective execution ПЗщ.

FIG. 5 - Panel protective execution ПЗщ-в.

FIG. 6 - Panel protective execution ПЗщ-п.

FIG. 7 - Panel protective execution ПЗщ-in trapezoidal shape.

FIG. 8 - Panel protective execution PZsch-p trapezoidal shape.

The protective panel (Fig. 1) consists of a front wall 2, a rear wall 6, a left side 4 strap, a right side 5 strap, an upper 7 strap, an earring 1, plates 3 and concrete 8. The panel includes a system of internal steel ties and anchors (Fig. 2).

The walls are front 2 and rear 6, the left side rails 4 and the right 5 are made of sheet metal of structural carbon steel 3 mm thick. The upper bar 7 is made of sheet metal of structural carbon steel 6 mm thick. The choice of the upper bar thickness is due to the provision of an equivalent class of protection for joints between panels.

The use of concrete 8 of two types is provided - B20 (M250) and B25 (M350).

The system of internal steel screeds and anchors (Fig. 2) is a system of structural elements distributed over the entire surface: screeds - a steel strip 3 mm thick, and anchors made of reinforcing steel with a diameter of 6 mm.

To protect walls and roofs, the following designs of rectangular panels are provided, depending on the number of installations in the protective structure:

- panels ПЗщ-н - are intended for mounting the lower (support rows) of the protective structure (Fig. 3);

- PZsch panels - for mounting subsequent (intermediate) rows of the protective structure (Fig. 4);

- panels ПЗщ-в - for mounting the upper (closing) rows of the protective structure (Fig. 5);

- panels ПЗщ-п - for mounting the protective structure of the walls above the door and window openings (jumper) in one row, as well as mounting the protective structure of the roof between the roof equipment and / or pipes in one row (Fig. 6).

To protect the upper rows of walls bounded by the roof slopes (pediment), protective trapezoidal panels are provided for the execution of the ПЗщ-в (Fig. 7) and ПЗщ-п (Fig. 8).

The main structural difference between the panel designs is the surface shape of the lower and upper faces - straight (supporting) or inclined at an angle of 30 ° (castle).

To ensure an equivalent class of protection for joints between panels with the panels themselves, the panel joints on the inside are additionally covered by a bar in the form of a strip of structural carbon steel 3 mm thick welded with an intermittent weld to the panels to be joined.

To ensure the stability of the protective structure of the walls or the roof, erected from several rows of panels, the panels are provided with plates 3 and earrings 1 (Fig. 1), which, after installation in the design position, are welded along the contour to the mating surfaces of the panels in this mesh for non-seismic zones ; pulled together with studs - for seismic zones.

The protective panel has a class of protective structure for resistance to small arms bullets (bullet resistance) - Br 4 according to GOST Ρ 51112 (amend. 4), which corresponds to the fifth class according to GOST Ρ 51112 (amend. 3).
