Combined sandwich type heat preservation layer structure

Abstract

The invention discloses a combined sandwich type heat preservation layer structure. The structure is characterized by comprising a heat preservation board, steel wire gauze and a combined sandwich piece; the combined sandwich piece comprises a pushing resistance sheet upper disc, a pushing resistance sheet lower disc, a double-rod penetrating nail and a connecting rod piece; through holes are formed in corresponding portions of the pushing resistance sheet upper disc and pushing resistance sheet lower disc respectively, gauze clamping grooves are formed in the pushing resistance sheet upper disc, and the pushing resistance sheet upper disc and the pushing resistance sheet lower disc are arranged on the front and back sides of a heat preservation plate; the steel wire gauze is arranged in the gauze clamping grooves, and the double-rod penetrating nail and the connecting rod piece penetrate through the heat preservation board from the through holes in the pushing resistance sheet upper disc and stretch out of the corresponding through holes in the pushing resistance sheet lower disc, wherein the double-rod penetrating nail and the connecting rod piece are casted in a wall body. According to the technical scheme, the problems are solved that in a sandwich combined process, a connection mode is not compact, the production efficiency is low, and the requirement for production conditions is high. The design is simple, no complicated structures are adopted, the production cost is reduced, and application and popularization of the sandwich combined process in a construction field are facilitated.

Description

technical field [0001] The invention relates to the construction field, in particular to a combined sandwich type insulation layer structure. Background technique [0002] In the current construction industry, the construction process of the wall requires the construction of the main body of the building and the insulation material at the same time. After the main body is completed, it can meet the current national energy-saving standards without additional insulation, ensuring that the main structure of the building and the outer insulation layer have the same service life. requirements. At present, there are two construction techniques, one is material self-insulation, and the other is that the wall is constructed by sandwich composite process. [0003] In the prior art, Patent No. CN104631667A discloses a non-welding assembled grid plate. In the technical solution of this patent, although the connection method is relatively reliable, the components are complicated, the a...
