Description

I

The invention relates to construction and can be used as a heat insulating element of external enclosing structures of buildings and structures erected in areas with a sharply continental climate.

Thermal insulation panels with heat-reflecting elements installed inside the structure and having a semicircular or parabolic shape II are known.

The main disadvantage of these panels is their low efficiency in operating conditions in areas with a severely continental climate.

The closest technological solution to the invention is a building heat insulation panel comprising outer layers and a bimetal reflecting element placed between the layers in the air gap 2.

The disadvantage of such a panel is; high metal consumption, since in each heat insulating panel a bimetallic sheet of steel and aluminum is installed over its entire area.

The purpose of the invention is to reduce metal consumption.

The goal is achieved by the fact that in a heat insulating panel comprising outer layers and a bimetal reflecting element, placed between the layers in the air pro- a puff, a reflecting element along the panel is made of bimetallic plates, between which a heat-reflecting screen is stretched.

Heat reflecting screen is made of fiberglass with a reflective layer or aluminum foil.

FIG. 1 shows a panel, in plan, not a section (at + 20 ° C) h in FIG. 2 then., (At a temperature above). in fig. 3 - the same (at temperature

below + 20c) 5 pas of fig. 4 - reflecting element, profile section.

The thermal insulation panel consists of two external concrete layers I, an air gap 2 between them. On the pins x 3 rigidly fixed in the outer layers x 1, the reflecting element 4 is freely suspended, consisting of: 1 and bimetallic plates: aluminum 5 and steel 6, between which a screen 7 made of fiberglass or aluminum foil is stretched across the entire area. A reflective layer is applied to both surfaces of the glass fiber.

When the bimetallic plates are in a neutral position, i.e. not bent.

.B hot, the period of operation at the outside air temperature above the bimetallic plates under the influence of the outside temperature is bent outwardly, bending the screen 7 simultaneously. The higher the temperature, the greater the reflecting capacity of the screen, as a result of which the outside thermal air does not penetrate into the room. In the cold period of operation i.e. at temperatures below + 20 ° C, bimetallic plates 5 and 6 are bent in the opposite direction, preventing leakage of warm air from the room.

The advantage of this panel is that there is an effective thermal insulation of the room as in

so cold in a hot period of exploitation, which is very important in areas with a continental and sharply continental climate, as well as a reduction in the metal intensity of the thermal insulation panel.
