Large-sized synthetic assembled structure apron plate

Abstract

Disclosed is a large-scale compound apron plate with fabricated structure, which pertains to building preformed piece, comprises a casting protection layer at the outside and a light middle layer for heat insulation and preservation. A strengthening connection frame is arranged in the middle of the casting protection layer, which is a cast of magnesium oxide, high-purity magnesium, ceramic granule and water; and the inside of the cast is paved with steel wire netting the two side of which is covered with glass fabric cloth. The apron plate has the properties of light weight, high strength, heat preservation and energy saving; the performance of explosion prevention and earthquake resistance, and the performance of fire protection can meet industry requirements. The apron plate of the invention is a green environmental protection preformed material which is applicable for large-scale buildings with high saftety and efficiency, and can realize factory production of building. The apron plate has the advantages of low cost, short construction period and good effect of in-door ventilation and noise absorption and insulation when being applied to construction.

Description

technical field [0001] The invention belongs to building prefabricated parts, in particular to a composite assembled structure enclosure board suitable for large buildings. Background technique [0002] The traditional wall material is brick, which not only wastes land resources, but also has a long construction period and many safety hazards. In recent years, some prefabricated wall bricks or wall panels have appeared. Because of their low strength, poor thermal insulation, fire prevention and ventilation performance, they cannot be used as enclosure walls for large buildings. Chinese patent application 200420052714.9 discloses "a high-strength wall panel", which is composed of an outer casing made of quick-setting cement, epoxy resin, magnesium chloride, and binder, and a foam filling block in the outer casing. It is equipped with glass fiber cloth and steel wire mesh to improve strength and impact resistance. This kind of wall has a certain strength and service life, bu...

AI Technical Summary

Problems solved by technology

This kind of wall has a certain strength and service life, but as a large-scale building enclosure, the shortcomings are: 1. Because the outer casing is made of magnesium chloride, it has strong hygroscopicity, and it will counteract moisture in rainy days. , In addition, the combination of magnesium chloride and epoxy resin will burst when it encounters high temperature combustion, and the foam plastic in the middle will also melt after being heated for a long time, which will affect the safety performance of the wall; 2. The filling body is a solid structure, The use function is single, and it cannot be connected with some geothermal devices, and the ventilation and heat preservation effects need to be improved; 3. The strength is improved only by a piece of steel wire mesh. The strength is not only insufficient and cannot be measured, it cannot be recognized by the industry for design
