The other ends of the supporting legs penetrate out of the heat insulatinglayer to be exposed out of the heat insulating layer, and the portions, penetrating out of the heat insulating layer to be exposed out of the heat insulating layer, of the supporting legs and the outer surface of the heat insulating layer are perpendicularly arranged or arranged by a certain angle. The steel wire net frame composite outer wall heat insulating plate can be widely applied to the outer wall heat insulating plate.

Description

technical field [0001] The invention relates to a building material, in particular to a steel wire grid composite external wall insulation board. Background technique [0002] At present, various material technologies in the construction industry are developing rapidly, especially with the development of prefabricated building models, the demand for prefabricated building materials is huge. In order to meet the construction environmental protection requirements of the construction industry and prefabricated buildings for new external wall insulation materials , For the traditional external wall insulation materials also put forward the requirement of upgrading. [0003] Exterior wall insulation boards currently on the market generally include an insulation layer and a concrete layer, and a steel wire mesh support frame is installed inside the insulation layer and the concrete layer.

AI Technical Summary

Problems solved by technology

[0005] (1) The thickness of the existing external wall insulation board is thin, the concrete layer has poor shear resistance, and the quality and life of the external wall insulation board are short. The specific technical problems are as follows: the external wall insulation board includes an insulation layer and a concrete layer, and the thickness of the concrete layer is average During on-site construction, the concrete poured on site will form a large pressure, which will squeeze the overall external wall insulation board. Under the pressure of the concrete poured on site, the external wall insulation board will produce a horizontal positive In addition, during the construction process, the pressure formed by the concrete poured on site produces shear stress that continuously expands outward inside the external wall insulation board. Due to the thin thickness of the external wall insulation board, the insulation layer can hardly withstand the shear stress, and the thickness is thin The concrete layer has poor shear resistance. After the construction is completed, the external wall insulation board will tear or even fall off due to the shear stress of the external expansion inside the exterior wall insulation board.

Due to the shear stress of outward expansion that always exists inside the external wall insulation board, it will also cause misalignment and separation between the steel wire mesh support skeleton and the insulation layer and the concrete layer, and there will also be misalignment and separation between the exterior wall insulation board and the concrete layer. Quality problems, the external wall of the building will also have water seepage problems, and the quality and life of the external wall insulation board is short

[0006] (2) The structure of the steel mesh support frame inside the existing external wall insulation board is simple, and the penetrating fastening force between the steel mesh support frame and the insulation layer and the concrete layer is poor. The specific technical problems are as follows: the steel wire support frame generally includes lateral supports Steel wires and vertical support wires, horizontal support steel wires and longitudinal support steel wires are interlaced, and the cross-connected horizontal support steel wires and longitudinal support steel wires of the existing steel wire mesh support frame are a single-layer structure, resulting in a gap between the steel wire mesh support frame and the insulation layer and concrete layer. The penetrating fastening force between them is weak, and a destructive stress will be formed between the steel wire mesh support frame and the insulation layer and the concrete layer. As time goes by, it is easy to cause misalignment between the steel wire mesh support frame, the insulation layer and the concrete layer. It even leads to the peeling off of the external wall insulation board or the concrete layer, causing serious construction quality problems

[0007] (3) The thickness of the existing exterior wall insulation board is thin, and the insulation performance of the thin exterior wall insulation board is also poor. At the same time, the steel wire mesh support skeleton structure inside the exterior wall insulation board is simple, resulting in poor overall rigidity of the exterior wall insulation board. The wall insulation board will be deformed and broken during transportation and construction
