Steel wire net frame composite heat-insulation sandwich wall board node and construction method thereof

Abstract

The invention relates to a steel wire net frame composite heat-insulation sandwich wall board node and a construction method thereof and belongs to the technical field of building energy-saving heat insulation. The steel wire net frame composite heat-insulation sandwich wall board node is of a T-shaped, L-shaped or Z-shaped node structure formed by mutually connecting steel wire net frame composite heat-insulation sandwich wall boards. The connecting position of the wall boards is a column body, each steel wire net frame composite heat-insulation sandwich wall board comprises a steel wire net frame formed by two steel wire net pieces which are mutually parallel and a plurality of cold-drawing obliquely-inserting steel wires for being connected with the two corresponding steel wire net pieces, a three-layer heat insulation board sandwiched between the two corresponding steel wire net pieces and concrete layers arranged on the two sides of the corresponding heat insulation board; the steel wire net pieces are formed through longitudinally and transversely intersection of steel wires in a welding mode; and each three-layer heat insulation board comprises a middle-layer thick main heat insulation board body and thin heat insulation board bodies which are arranged on the two sides of the corresponding main heat insulation board body in a spaced mode, every two corresponding heat insulation board bodies on the two sides are distributed in a horse-tooth-stubble shape on the two sides of the corresponding middle main heat insulation board body, and the heat insulation board bodies on any side can cover the abutted seam positions of the middle main heat insulation board bodies.

Description

technical field [0001] The invention relates to a wall body, in particular to a steel wire grid composite thermal insulation sandwich wall panel node and a construction method thereof, belonging to the technical field of building energy conservation and thermal insulation. Background technique [0002] Composite thermal insulation sandwich wall is to put thermal insulation materials (such as polyphenylene, rock wool, glass wool, etc.) between two walls, and set tie pieces between the inner and outer leaf walls to form a sandwich thermal insulation composite wall. The wall is generally composed of an inner leaf wall, an insulation layer, and an outer leaf wall. The thermal insulation material is arranged in the middle of the outer wall body, which is beneficial to exert the protective effect of the wall material itself, thereby eliminating the need for the reinforcement surface of the insulation layer and material layer. layer, the cost is relatively lower. At present, the t...

Problems solved by technology

However, since the core material insulation board is often assembled piece by piece, it is easy to cause a cold bridge at the seam to affect its insulation effect; the two sides of the insulation layer are relatively flat, and it is difficult to ensure the joint force and rigidity of the connection between it and the concrete layer. Difficult to guarantee
