Lightweight sandwich panel, especially for roofs and walls of buildings

Technical field

The technical solution relates to a lightweight insulating sandwich panel designed as a structural element for roofs and walls of buildings.

BACKGROUND OF THE INVENTION

Lightweight thermal insulation panels for the building envelope are known. They consist of a thermal insulation board on which a metal sheet is glued on both sides. At the same time, the face of the outer sheet metal layer requires a relatively demanding anticorrosive treatment and its service life is nevertheless limited. The disadvantage of these known panels is their high price.

The aim of the technical solution is to create a self-supporting thermal insulation panel, which would retain a very low density and a long service life at relatively low production and assembly costs. Aesthetically pleasing for both roofs and walls of buildings.

The essence of the technical solution

This object is achieved by a lightweight sandwich panel, in particular for roofs and walls of buildings, which consists of a board of thermally insulating material to which a longitudinally corrugated board of weather-resistant material is attached, the two boards being in contact with each other glued or welded. This creates a light beam with a cross-section moment corresponding to the sum of the thicknesses of the two plates. This results in a relatively high flexural strength without affecting the panel weight.

In a preferred embodiment, the insulating board is provided on the inside with a rigid facing layer which, on the one hand, forms the viewing surface of the panel and, on the other hand, substantially increases the flexural strength of the panel.

In order to seal the joints between the panels to be brought together, the corrugated board preferably protrudes over the edge of the insulating board on at least one side of the panel, or the facing layer forms a groove on at least one side of the panel and a tongue on the opposite side.

In a particularly preferred embodiment, the thermally insulating board is made of expanded polystyrene or polyurethane, the longitudinally corrugated board of pressed bituminous cardboard and the rigid facing layer is formed by a sheet which is preferably provided with parallel longitudinal embossments.

Examples of technical solution

The self-supporting thermal insulation panel consists of a plate 1 of thermal insulation material, in particular of polystyrene foam, to which a longitudinally undulating plate is glued at the points of contact.

3. weather-resistant material, in particular compressed bitumen cardboard. The corrugated plate 3 is glued with an overlap 4 on one side of the panel and generally also on one face of the panel, allowing the overlap and the sealing of the panels laid on the slide. On the inside of the thermal insulation board 1 is adhered the facing layer 5 formed by galvanized sheet. The sheet is provided with longitudinal punches 6 which increase the longitudinal stiffness of the panel. On the side of the panel the plate forms a groove 7, on the other side the tongue 8.

The described structure may be made of materials other than those mentioned: the heat insulating plate 1 may be of other materials capable of transmitting shear stress, eg polyurethane, polyvinyl chloride, particleboard, etc., the corrugated plate 3 may be eg fiberglass or plastic, for example, umacart or plastic plate may serve as the facing layer 5 instead of sheet metal. The corrugated plate 2 may have a different shape in the profile than the sine wave, see for example Fig. 2.

From the described panels it is possible to create a building envelope. However, they are particularly advantageous for roof construction, where the panels are laid on parallel girders with a pitch of up to 2 m per pitch, overhangs 4 prevent water from penetrating the joints between the panels and seals located between the groove 7 and tongue 8 buildings. The panels thus connect the load-bearing function with the thermal insulation function, forming both the roof covering and the soffit in the space under the roof and sealing against water and steam. The interior of the panel is easy to adjust paint or spray.
