Steel wire net frame composite outer wall heat insulating plate

Abstract

The invention provides a steel wire net frame composite outer wall heat insulating plate. The technical problems that as for an existing outer wall heat insulating plate, the thickness is small, the anti-shearing capacity of a concrete layer is poor, the quality life of the outer wall heat insulating plate is short, penetrating fastening force between a steel wire net supporting framework and a heat insulating layer as well as the steel wire net supporting framework and the concrete layer is poor, the heat insulating performance of the outer wall heat insulating plate is poor, the overall rigidity of the outer wall heat insulating plate is poor, and the outer wall heat insulating plate deforms and fractures in the conveying and constructing processes are solved. The steel wire net frame composite outer wall heat insulating plate is provided with a heat insulating layer, a concrete layer is arranged on one side of the heat insulating layer, and a steel wire net supporting framework is arranged in the heat insulating layer and the concrete layer in a penetrating mode and further provided with supporting legs. 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. Layers are connected, and the steel wire mesh support frame is provided with support legs, w...

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
