Shingle unit structure of light house

Abstract

The invention discloses a shingle unit structure of a light house, which comprises a metal inner wallboard and a metal outer wallboard which are provided with reinforcing ridges, and a heat-preserving foaming filler layer. The technical point lies in that the lap joints at two ends of the metal inner wallboard and the metal outer wallboard are self-locking splicing hasp structures. In the foamingand expanding process, the heat-preserving foaming filler layer enables the lap joints at two ends of the metal inner wallboard and the metal outer wallboard to form self-locking splicing hasp structures to totally seal the expanded phenol formaldehyde foam in a mold formed between the metal inner wallboard and the metal outer wallboard and to totally seal the splicing hasps so as to enable the metal inner wallboard and the phenol formaldehyde foam layer to form an integral structure without disengaging with each other. The finished product can not crack under vibration during transportation or installation, so the upper and lower metal layers can not disengage with the phenol formaldehyde foam. In this way, the purpose of the invention is realized. The shingle unit structure has the advantages of simple and reasonable structure, repeated use, safety and reliability, low cost, long service life and wide application range.

Description

technical field [0001] The invention relates to the technical field of light-weight houses for civil or industrial buildings, in particular to a wall panel unit structure for light-weight houses. Background technique [0002] As we all know, the polystyrene foam layer or polyurethane foam plastic layer has good thermal insulation and heat insulation effects, and has been widely used in light-weight buildings, steel factory buildings and temporary buildings in recent years. To the thermal insulation and heat insulation of building walls. Due to the poor fire performance of the polyphenylene foam layer or polyurethane foam plastic layer, and a large amount of toxic and harmful gases will be released when burning, although adding a certain amount of flame retardant additives can relatively reduce the burning of polyphenylene foam or polyurethane foam plastic products. However, when the temperature is high, it still cannot be fundamentally flame retardant and belongs to the fla...

Problems solved by technology

Because phenolic foam products have the disadvantages of high brittleness and easy pulverization on the surface, although liquid thermosetting phenolic resin is mixed with surfactant, foaming agent, curing agent and other additives, it is processed between the upper and lower metal plates. The phenolic foam board is finished, but when the finished product vibrates during transportation or installation, it will be brittle and even separated from the upper and lower metal plates
