Description

Technical Field

[0001] The utility model relates to the technical field of building plates, in particular to a large square cabin plate. Background Art

[0002] The wall panel materials used to manufacture shelters are commonly known as shelter panels. Existing shelter panels are usually made of polyurethane sandwich panels, which have a structure of two metal plates on the outside and a foamed polyurethane material layer in the middle to form a sandwich structure.

[0003] According to the records of the Chinese utility model patents with publication number CN202782078U, titled "Automatic production line for high-temperature bonding and molding polyurethane sandwich panels", and publication number CN201874149U, titled "New polyurethane color steel sandwich panels", the existing preparation method of the large panels of the square cabin using polyurethane sandwich panels generally adopts a high-temperature negative pressure bearing method, that is, a large amount of glue is applied on the bonding surface of the upper metal plate, the lower metal plate, and the foamed polyurethane plate, and then high-temperature pressurization is used to bond the upper and lower metal plates and the middle polyurethane plate layer together, wherein the high-temperature pressurization bonding process usually takes a long time and requires the use of a large amount of glue, which is inefficient and costly.

[0004] In addition, when the existing large square cabin panels using polyurethane sandwich panels are used in plateau areas, due to the low air pressure in the plateau environment, the free air in the sandwich panels can easily move and concentrate through the tiny holes in the foam material structure to the weak structures or uneven surfaces of the outer metal layer, which often causes stress concentration in some areas of the metal plates on both sides of the panels, resulting in hollowing and bulging.

[0006] According to a first aspect of the utility model, a large panel for a shelter is provided, comprising: two metal plates, a honeycomb panel and polyurethane;

[0007] A honeycomb panel and polyurethane are sandwiched between two metal plates. The honeycomb panel is attached to the outer metal plate, and the polyurethane is attached to the inner metal plate.
