(54) PROTECTIVE PANEL (57) The invention relates to the construction, in particular to the enclosing structures of the walls and partitions of industrial buildings and engineering structures. The purpose of the invention is to reduce material consumption, increase manufacturability and performance. The fencing panel is made in the form of a prefabricated slab of filling which is embedded in a contour reinforced concrete frame. The latter is made of dispersion-reinforced basalt fiber concrete and is provided along the perimeter by protruding keys on the edges of its body, with adjustable pitch equal to two key lengths. 5 il.

The invention relates to the construction, in particular to the enclosing structures of the walls and partitions of industrial buildings and engineering structures.

The purpose of the invention is to reduce material consumption, increase manufacturability and performance.

FIG. 1 shows a general view of the enclosing panel; in fig. 2 shows section A-A in FIG. I; in fig. 3 shows a section BB in FIG. one; in fig. 4 — node I in FIG. 2; in fig. 5 - arrangement of keyway slots.

The fencing panel consists of an outer reinforced concrete contour frame 1 arranged around the perimeter of the structure and reinforced with welded meshes 2. In the outer reinforced concrete contour frame 1 there is a monolithic internal slab

4 and grooves 5 arranged in regular pitch.

The inner filling plate is provided with steel mounting loops 6 protruding beyond its longitudinal face to seal the external reinforced concrete contour frame I in the frame. The supporting parts of the enclosing panel in the upper and lower parts of the external reinforced concrete contour frame 1 provide for steel fixings 7 for fastening to the supporting structures of the frame.

In the manufacture of the fencing panel, initially prepared in metal form, fitted with mounting loops 6, the inner slab 3 of basalt fiber concrete filling with a thickness equal to the thickness of the outer reinforced concrete contour frame 1, width not less than half the width of the fencing panel and less than twice the length the width of the cross-section of the outer contour frame 1. This size of the inner filling plate 3 ensures its free installation in the metal mold with a gap

Rebar grids 2, fixing parts 7 for fastening the fencing panel to the frame elements and concreting the outer reinforced concrete frame 1 with subsequent heat treatment are installed in the resulting gap between the form board and the inner slab 3 of dispersion-reinforced basalt fiber-reinforced concrete.

The basalt-fiber concrete keys 4 protruding beyond the edges of the inner slab 3 of the filling and located along its perimeter with a regular step at a distance equal to their two lengths are the formwork for the outer reinforced concrete contour frame 1 made of monolithic concrete and buried in the body the latter, form an equal strength prefabricated monolithic keyed joint after cross-casting.

This arrangement of the keys 4 is determined by the dependencies

Conditions for maintaining the same width of the external reinforced concrete contour frame I

for ease of reinforcement.

The inner filling plate 3 is made of dispersion-reinforced basalt fiber concrete without the use of steel reinforcement and with a thickness equal to the thickness of the outer reinforced concrete contour frame 1. Performing a prefabricated inner filling plate in this way reduces the intensity and complexity of the fabrication of the structure.

In addition, due to the use of an inner filling plate 3 made of basalt fiber concrete based on the use of coarse basalt fibers with a diameter of 150-400 µm, the durability and fire resistance of the structure are increased.
