Description

The utility model relates to the field of construction and relates to the construction of a three-layer external wall panel.

Known three-layer outer wall panel containing the outer and inner reinforced concrete layers, the heat-insulating layer in the form of plates located between them, flexible connections connecting the panel layers and the sealing element of the gap between the insulation plates (see the journal "Industrial and civil engineering" No. 12/2010, article “On the influence of the construction and material of bonds between concrete layers of a three-layer external wall panel on its heat engineering uniformity”).

In a known solution, the element for sealing the gap between the insulation plates can be made in the form of adhesive tape or in the form of foam filling the joints between the insulation plates. However, these solutions have several disadvantages:

- the complexity of the work;

- the duration of the process;

- a high probability of defects, as an additional operation is wedged into the panel assembly process, which was debugged to automatism.

The proposed solution eliminates these disadvantages.

The technical result is a reduction in labor costs for the manufacture of the panel.

This is achieved by the fact that in a three-layer outer wall panel containing the outer and inner reinforced concrete layers, the heat-insulating layer between them in the form of plates located between them, the flexible connections connecting the panel layers and the sealing element of the gap between the insulation plates is made in the form of a layer of soft insulation located at least in the upper part of the end of the rigid insulation adjacent to the flexible connections when assembling the panel.

Such a constructive implementation of a three-layer outer wall panel allows you to provide the following:

- the gap between the insulation plates formed during loose compression of the flexible joints is protected from leakage of the concrete mixture and its mortar component, and, as a result, the thermal performance of the panel is increased;

- reduction of labor costs during assembly of the panel;

- acceleration of the panel manufacturing process;

- more reliable protection of the joint, since the element for sealing the gap is made and installed previously, and not during the assembly of the panel.

The essence of the utility model is illustrated by drawings, where

figure 1 shows a vertical section of a three-layer outer wall panel with flexible connections;

figure 2 is a fragment of the compression of flexible ties with a heater using the element of sealing the gap;

figure 3 - element sealing the gap between the plates of insulation.

The three-layer outer wall panel contains the outer 1 and inner 2 reinforced concrete layers, the heat-insulating layer 3 located between them and flexible connections 4 connecting the panel layers.

The heat-insulating layer 3 is made of a rigid insulation in the form of plates, for example, of expanded polystyrene or of hard mineral wool.

Flexible connections 4 provide interaction between the layers, transfer the loads of the outer layer to the inner layer, and minimize the efforts on the inner layer from temperature and climatic influences. Flexible connections can be made of metal or non-metallic alkali-resistant materials. In the manufacture of the panel with loose compression of the flexible connections by the insulation between the insulation plates, a gap is formed with a thickness of the diameter of the rod. In this regard, when concreting, it is possible to leak into the gap of the concrete mixture and its mortar component, which is not allowed according to the “Recommendations for the design of exterior three-layer wall panels with a heat-insulating layer of PENOPLEX polystyrene foam extrusion plates for residential and public buildings”, as it leads to a decrease thermotechnical indicators of the panel.

In this regard, they protect the joints of the plates of the insulating layer by means of an element 5 made in the form of a layer of soft insulation located at least in the upper part of the end of the rigid insulation adjacent to the flexible connections when assembling the panel. Element 5 is placed on the surface of the hard insulation previously, before the manufacture of the panel. In the manufacture of the panel, the process of installing insulation boards is fast, high-quality and leads to a simplification of the assembly process, a decrease in the complexity and increased reliability of the three-layer external wall panel during operation.
