(54) COATING PANEL BUILDINGS AND FACILITIES

one

The invention relates to the construction and, in particular, relates to the construction of a building covering panel or structure.

There is a known coating panel, including a reinforced concrete ribbed plate on the surface of which vaporization, insulation and water insulation II are successively laid.

The disadvantages of this design are the increased consumption of concrete for the ribs, determined by the necessary technical gradients for removing the panel from the mold, the increased consumption of steel due to the increased panel weight, the increased construction height, and the greater labor intensity of panel manufacture at the factory.

The closest in technical essence to the proposed building covering panel and structure, comprising a reinforced concrete slab with a shelf and ribs and an insulating element connected to it, placed on the lower side of the shelf r2j.

The disadvantages of this coating are the high consumption of materials, the complexity of the manufacture and installation of the panel.

The purpose of the invention is to reduce material consumption, labor-intensiveness of manufacturing and construction and installation work, about 30 and water resistance in places where the insulating element is supported on the ribs and temperature deformations in the insulating element.

This goal is achieved by the fact that in a panel covering the building and structure, including a reinforced concrete slab with a shelf and rib and an insulating element connected to it, located on the bottom side. the shelves, the panel edges of the shelf are made with grooves in which the insulating element is fastened.

In addition, the plate is equipped with an elastic sealing gasket,

meshed into the groove under the insulating element.

At the same time, the insulating element is provided with elastic inserts and is made of composite short-circuit parts between which the inserts are placed.

FIG. 1 panel, transverse section; in fig. 2 - section AA on fng. one.

The panel includes the reinforced concrete slab I itself and the insulating element 2, which extends into the fins 3 of slab 1 by the value d. The remaining part of the rib b is determined from the conditions of the rib operation on the tangential stresses and ensuring the required temperature in the room. The insulating element can be supported on the ribs by means of spacers 4, placed in the longitudinal grooves of the ribs. In the case of the formation of treshin at the points of contact, the isolate of the shunnogr element with the concrete pressed, preferably made of elastic material, fills the crack. The insulating element can be made composite along the length with blocks 5 of insulating material, between which inserts b with a profile, for example, I-o6paJMMM element 7, which overlaps the junction of adjacent blocks, are placed. Inserts 6, 7 are squeezed out of an elastic testisol of the virgin material to ensure the temperature deformations of the insulating blocks and prevent their destruction in the zone of contact with the concrete. Profile element 7 can be made of metal, asbestos cement, plastics. It serves to overlap the whiskers between the insulation blocks and provides a diverse ceiling decoration.

The insulation element can be made both single-layered and multi-layered. In particular, in FIG. 2 shows an insulating element including 1 asbestos cement sheet 8, a heat insulating unit 5. The heat insulating layer is made, for example, from polystyrene foam. Asbestos sheet is. carrying and performs simultaneously decorative and fireproof

If necessary, a paroizolation layer, for example, from plastic spitting, can be placed between the decorative sheet and the thermal insulation layer.

The barrier between the reinforced concrete rib and the insulating element is protected by a pad of elastic material and epoxy glue 9 to prevent moisture from escaping.

The slab is concreted in one stage.

Before concreting, an insulating element is placed on the mold tray,

 which is attached either to the pallet or to the sides of the molds. The reinforcement is then installed, prestressing and concreting are completed. The panel can be made of both heavy and lightweight concrete.

The implementation of the coating panel according to the invention reduces the consumption of concrete and metal by 5-1%, significantly reduces the labor intensity of construction and installation works, as well as only the work on the processing of panel joints is performed on the construction, reducing the consumption of materials for external fences due to the reduction panels and exclude freezing of the coating along reinforced concrete ribs due to embedding an insulating layer in them.
