Abstract

Usage: panel designs and methods for their manufacture. SUMMARY OF THE INVENTION: A three-layer panel includes outer and inner lining, between which there is a heater, a frame of longitudinal ribs 4 and 5 and a gasket 6 of a material with a long recovery time, placed between the ribs 4 and 5 and insulation 3. Walls of the longitudinal ribs 4 and 5 made in length with alternating holes and jumpers. Jumpers rib 4 are offset relative to the jumpers rib 5, do not overlap each other. The panel is manufactured as follows. First, the frame is assembled from the longitudinal ribs 4 and 5, then to the inside of the ribs 4 and 5 the gaskets 6 are made from viltherm and the calculated amount of insulation 3 is poured into the panel cavity. When foam insulation 3 is heated, foam collapses and decreases in volume and reduced volume the gasket 6 is retained even after the insulation has cured. After 15-30 days, the volume of the vilterma is restored and it fills all the voids formed by shrinkage of the insulation 3. Part of the vilterma leaves the panel through the holes beyond the outer surface of the ribs 4 and 5, forming protrusions 10. When the panels dock, these protrusions 10 overlap each other. another, uniformly filled with a vilaterm joint. When using insulation, in the process of foaming which does not develop the pressure required to compress the gasket 6, it is compressed before installation. 4 il. 1 h. and 2 sec. f-ly.

Description

The invention relates to the construction, in particular to sandwich panels and methods for their manufacture.

The purpose of the invention is to simplify manufacture and improve the quality of the panel.

FIG. 1 shows a sandwich panel; general view; in fig. 2 is a view A of FIG. 1, longitudinal edge; in fig. 3 is a section BB in FIG. 1; in fig. 4 - panel with butt joint fragment, longitudinal section.

The three-layer panel includes an outer 1 and an inner 2 skin, between which there is a heater 3, a frame of longitudinal ribs 4 and 5 and a gasket 6 placed between the ribs 4 and 5 and the insulator 3. The walls of the longitudinal ribs 4 and 5 are alternated in length holes 7 and jumpers 8 and 9. Jumpers 8 edges 4 are offset relative to the jumpers 9 edges 5, do not overlap each other in the plan on the longitudinal edge 5 (figure 2). The maximum length of the jumpers 8 and 9 is equal to the length of the holes 7, and the minimum is chosen constructively according to the available technology. The shells 1 and 2 are set offset from the longitudinal ribs 4 and 5, respectively, and fixed by known methods.

The panel is made as follows.

First, the frame is assembled from longitudinal ribs 4 and 5, then a gasket b from wilaterma is installed to the inner side of ribs 4 and 5, for example, it is glued, and the estimated amount of insulation 3, such as FRP foam, is poured into the panel cavity. When vilaterm is foamed under the action of foaming pressure, it is compressed and reduced in volume and the reduced volume of gasket b is retained even after curing of the foam. After 15-30 days, the volume of vilaterma is restored and it fills all the voids formed as a result of the shrinkage of the foam. Part of the vilterma leaves the panel through the holes 7 beyond the outer surface of the ribs 4 and 5, forming protrusions 10. When the panels dock, these protrusions 10 overlap each other, forming a joint evenly filled with vilaterm. When using insulation, in the process of foaming which does not develop the pressure required to compress the gasket 6. then it is compressed before installation.

The proposed three-layer panel is easy to manufacture, as it does not require additional equipment. The presence of a vaterterm gasket in the panel provides for an increase in its quality by filling the voids of the cavities formed after shrinkage of the insulation. The installation of panels is simplified due to the lack of effort in the joint and additional work related to the thermal insulation of the joint, for example, the casting of mastic. Due to the fact that the vilaterm in the joint will be in a tense state, the shrinkage of the insulation for several months is compensated.
