Description

(54) WALL PANEL

one

The invention relates to building structures, in particular to multi-layered panels with flexible connections.

Multi-layered panels of external walls are known, consisting of a supporting reinforced concrete ribbed plate, filled with insulation and rigidly attached to it with the help of steel cantilever plates of suspended reinforced concrete lining 1.

The disadvantage of these structures is that the rigid connections located in the upper zone of the panel provide the possibility of thermal deformations only along the height of the panel. Deformations in length, especially in long two-module panels, can lead to the formation of cracks in the outer facing layer, to the location of the connecting elements in the zone of the horizontal joint, in case of possible leaks - to corrosion and destruction of the connecting cantilever plates.

The closest to the technical essence of the invention is a wall reinforced concrete panel comprising flexible outer and inner reinforced concrete layers and insulation between them 2.

However, the manufacture of such a panel is difficult and time-consuming due to the increase in the timing of the panel at the molding station due to the need for sequential postoperative laying of the concrete of the outer layer and its vibration treatment, laying of insulation, installation of reinforcement and the laying of concrete of the inside layer and its vibration treatment, the need to use non-absorbent materials as insulation. materials or materials that are lovable, but with preliminary packaging in a waterproof sheath, the possibility of partial saturation of moisture with moisture pilaf processing molded panel.

The purpose of the invention is to increase the industrial production and reduce labor costs.

This goal is achieved by the fact that in a wall panel including flexible outer and inner reinforced concrete layers and insulation placed between them, the flexible connections are made in the form of embedded parts placed in the outer layer, the protruding parts of which have horizontal platforms located at a height equal to the calculated thickness of the insulation, and the inner layer with the narrow part facing inside the panel of the cone holes through which the inner layer is connected to the horizontal platforms of the mortgages Aley. The inner layer can be connected to the horizontal pads of embedded parts by means of bolts. FIG. 1 shows the proposed panel in axonometry; in fig. 2 shows section A-A in FIG. 1. The wall of reinforced concrete panel consists of outer 1 and inner 2 layers and heat insulation 3 between them. The inner layer 2 is made with tapered holes 4. Layers 1 and 2 are interconnected by means of bolts 5 and inserts 6 (flexible connection) having horizontal platforms 7 with threaded holes 8. Bolts with attachments 7 of inserts 6 are fastened nuts 9. The panel is made in operation. In a separate horizontal form, the outer layer 1 is formed with the embedded parts 6 fixed therein, installed so that the horizontal platforms 7 are located at a height equal to the calculated thickness of the insulation 3. Separately, the inner layers 2 are formed in the cassettes, the conical holes 4 of which are formed spacer cones of cassette sheets. Then alternately on the outer layer I stack insulation 3 and the inner layer 2, respecting the coaxiality of the tapered 4 and razbovy 8 holes; then install the bolt 5 with the washer 9 through the tapered holes 4 into the threaded holes 8, ensuring the connection of the outer 1 and inner 2 layers. Strengthening both layers 1 and 2 using bolts 5 produces a compression of the insulation to the calculated thickness. The proposed construction of the panel is simpler to manufacture, requires less labor, allows the use of virtually any insulation, regardless of its capacity and the use of cost-effective, stamped fixtures. The economic effect of introducing the proposed design is due to the increased industrialization of the panels, due to the separate production of the outer and inner layers with a high degree of use of high-performance cassette equipment, which makes it possible to increase the productivity of production lines by about 30%. This saves fuel by separately steaming two thin layers of panels. Reducing the time of the production cycle saves labor costs in the amount of 0.17 rubles / m total area. Claims of the invention A wall panel comprising interconnected outer and inner reinforced concrete layers and a heater placed between them, characterized in that, in order to increase industrial production and reduce labor costs. flexible connections are made in the form of embedded parts placed in the outer layer, the protruding parts of which have horizontal platforms located at a height equal to the calculated insulation thickness and the inner layer with the narrow inside part facing the panel with conical holes through which the inner layer is connected to horizontal land plots. 2. The panel according to claim 1, characterized in that the inner layer is connected to the horizontal pads of embedded parts by means of bolts.
