Abstract

FIELD: construction of large-panel public and industrial buildings. SUBSTANCE: wall panel made from heat-treated cellular concrete is provided with internal anchors arranged in two rows through panel thickness. Stretched continuously over said anchors are reinforcing strings in a biaxial direction with an identical force in the rows. Anchors have support flats, front and rear forked protruding bars which are used for connecting by rods the anchors adjacent in the depth of panel. Front protruding bars are used as hoisting rings for connecting the panels to one another by means of fastening parts. Reinforcement is coated with corrosion-resistant material while the panel is covered on the outside with watertight material. EFFECT: improved design. 13 cl, 7 dwg

Description

 The invention relates to construction and can be used in the manufacture of external wall panels for large-panel housing construction, civil buildings and industrial buildings.

 Known external wall panel of lightweight or cellular concrete, reinforced in the biaxial direction by prestressed reinforcing bars located in a plane passing through the middle of the thickness of the panel. At the same time, the reinforcement is made with kink at the intersections and end anchors from reinforcement scraps are welded to the ends of the stressed rods, and the panels are connected by welding through embedded parts [1].

 The disadvantage of this wall panel is that when the reinforcement is located in the middle of the thickness of the product and the bends present on it, at the intersection of the rods at the time of the load transfer, lateral forces appear in the reinforcement, which act destructively on the thickness of the concrete of the panel, as a result of which cracks appear in the panel direction of bar reinforcement, which reduces its rigidity and strength. In this regard, the panel is reinforced with non-tensile frames in the vertical and horizontal directions. In addition, this wall panel requires a large metal consumption when using large-diameter bar reinforcement, both tensioned and non-tensioned, since tensioned reinforcing bars are laid with a length exceeding the length of the panel by 40-50 cm. The manufacturing technology of this wall panel is complex and time-consuming, since does not create the possibility of using a mechanized method of laying and welding reinforcing bars. At the same time, the design of this external wall panel does not make it possible to avoid a welding operation when assembling a building from these panels.

 The closest in technological essence is a prestressed string foam-silicate plate reinforced with string reinforcement with a diameter of 0.8 mm in one longitudinal direction with the location of the reinforcement strings in separate sections in two rows along the thickness of the panel and at a distance of two centimeters across the thickness of the plate [2].

 The disadvantage of this cellular concrete slab is that it has low crack resistance, stiffness, and strength, since they depend only on the adhesion of the concrete solution to the metal, high metal consumption, low labor productivity in manufacturing, and the inability to connect one slab to another .

 The purpose of the invention is to increase crack resistance, stiffness, strength and bearing capacity, reduce metal consumption and ensure its connection with other panels by means of a bolted connection.

 The goal is achieved by the fact that the wall panel, including heat-treated cellular concrete and reinforcement in the form of strings stretched in two rows along the thickness of the panel, is equipped with internal anchors located in two rows along the thickness of the panel, the reinforcement strings are continuously and closed tensioned on the anchors in a biaxial direction with with the same effort in the outer and inner rows, the anchors are equipped with bearing pads, front and rear fork-shaped outlets with holes, the rear outlets of adjacent anchors of the outer and inner row facing each other in are connected by rods and axles, recesses are made on the end surfaces of the panel, where the front outlets go out, which act as lifting loops and serve to connect to other panels through connecting parts with axles and bolts with nuts and washers, moreover, when the panel is located in the corner of the building recesses are made on its side surface for vertical anchors, in addition, the panel can be with one or two window openings or with window and window-door openings, and the outer surface of the panel is covered protective moisture-proof material, and the reinforcement is covered with a protective corrosion-resistant material.

 Wall panel 1 (figure 1, 2) includes heat-treated cellular concrete 2 (figure 3) and reinforcement 3.4 in the form of strings stretched in two rows along the thickness of panel 1, panel 1 is equipped with internal anchors 5, 6 (figure 3 ) and 7, 8 (Figs. 4, 7) located in two rows along the thickness of the panel. String reinforcement 3, 4 (Fig.3) is made continuous and closed and stretched on anchors 5, 6, 7, 8 in a biaxial direction with the same force in the outer and inner rows. Anchors 5, 6, 7, 8 (Figs. 3, 4, 7) are equipped with supporting pads 9 (Figs. 4, 5, 7), front 12, 13 (Figs. 4, 5) and rear 10, 11 (Fig. 4, 7) fork-shaped outlets with holes 14, 15 (Fig. 4). The rear outlets 10, 11 facing each other (FIGS. 4, 7) of adjacent anchors of the outer 7, 8 and inner 5, 6 rows are connected using rods 16 (FIGS. 4, 7) and axles 17; on the end surfaces of the panel there are recesses 18 (Figs. 1, 6), where the front outlets 12, 13 (Figs. 1, 4, 6) go out, which act as lifting loops and serve to connect the panel 1 by means of connecting parts 19 (Fig. 6 ) with axles 20 and bolts with nuts and washers (not shown in the drawings). Moreover, when the panel is located in the corner of the building, the recesses are made on its side surface for vertical direction anchors. In addition, the panel 1 (Fig. 1) can be made with one or two window openings (not shown in the drawings), or with window and window-door openings 21 (Fig. 1), and the outer surface of the panel is covered with a moisture-proof protective material, and the fittings are coated with a protective corrosion-resistant material.
