Description

(54 | HEAT-INSULATING .PANEL

The invention relates to elements of building structures.

Thermal insulating structures are known, which are a partitioned shell with tubular sections filled with a light, flowable heat insulating material fl.

The disadvantages of this design are the presence of gaps between the sections and the danger of operational precipitation of the aggregate, as this creates through bridges of cold.

Closest to the present invention, there is a heat insulation panel comprising a skin and a middle layer in the form of a shell, forming a section filled with friable heat insulation 2.

The disadvantages of the known panel are the possibility of the formation of gaps between the sections during the installation of the element and the danger of insulating insulation when isolating steeply inclined and vertical planes, as well as pipelines. Such a draft will lead to additional heat loss (m

cold bridges).,

 "

The purpose of the invention is the elimination of through cold bridges.

This goal is achieved by the fact that in the heat insulating panel j; comprising a skin and an average layer in the form of a shell forming tubular sections filled with friable thermal insulation; the tubular sections are arranged in two rows in a checkerboard pattern.

The tubular sections are made of contacting omegoobraznyh elements.

A protective and / or reinforcing coating may be applied to the outer surfaces of the product.

FIG. 1 shows a heat insulating product, axonometric image, FIG. 2 the same, the cross-section (in the sections of the product there was a deposit) J

20 of FIG. 3-6 - that is, options; in fig. 7 - the same, with a protective and / or strengthening coating.

The heat insulating product contains a shell 1, divided into

25 tubular sections, and filler. A protective and / or reinforcing coating 3 may be applied on the outer surface of the product.

The shell 1 can be made 50 by gluing or welding from sheet materials, using plastics, paper, cardboard including asbestos, (figs. 3, 4 and c), as well as extruding plastics., (Fig. 4). The omegoobrazny element can be made up of arcs of the same radius and straight (Fig. 3A), of arcs of different radii, from straight and curved segments (Fig. 5 and b). The surface of the product may be wavy (Fig. 3-5) or flat (Fig, 6). The wavy surface of the product increases the rigidity of the shell, and when laying between the panel skins creates additional closed air cavities with a relatively low thermal conductivity.

The same cavities can serve as channels for natural or artificial drying of the product during operation.

In the product there are no gaps between the tubular sections and even when the insulation of the insulation does not form cold through bridges, which improves the performance of the product compared to the prototype.

Since the sludge insulation is not dangerous, any porous material can be used as a filler, for example perlite expanded sand, vermiculite, peat, sawdust, lignin, shredded waste paper, silipore, stelopora, crushed bark, mineral wool, etc. materials and waste.

The product has a coating 3 that repeats the relief of the shell or smoothes this relief. The coating hardens the surface, products and protects against mechanical and climatic influences and can be paint, polymer, metal, cement or gypsum mortar, bitumen, ice, etc. The coating can be applied by spraying, watering, etc. Such a product performs the functions of a wall or roof panel and has a good appearance.

Products are fireproof and flame retardant in the manufacture of a shell of asbestos materials and fireproof filler.

They are used as high-performance plate material along with mineral wool products and foam plates.
