Structure self-heat-insulation concrete wall plate and manufacture method thereof

Abstract

The invention discloses a structure self-heat-insulation concrete composite wall plate and a manufacture method thereof. The wall plate comprises an internal concrete layer, an heat insulation core board, an external concrete layer and a reinforcement cage, wherein, the heat insulation core board is arranged between the internal concrete layer and the external concrete layer; an oblique reinforcement cage passing through the heat insulation core board connects the internal concrete layer and the external concrete layer into a whole; the reinforcement case comprises a reinforcement cage of the internal concrete layer, the oblique reinforcement cage and a reinforcement net of the external concrete layer. The wall plate concerns the 'heat bridge' effect passing through the oblique reinforcement of the heat insulation core plate, and ensures that the content of the heat insulation core plate can be determined by thermodynamic engineering performance of the composite wall plate. The wall plate can be manufactured flexibly and conveniently, can meet the requirement of building energy-saving design standard without an extra heat insulation measurements, overcomes the defects of external heat insulation of the prior external building wall, ensures the same service life of building heat insulation and main structure, reduces later maintenance cost for the heat insulation system of the building, is in accordance with the policies of energy conservation, emission reduction and sustainable development in China, and has good economic and social benefits.

Description

technical field [0001] The invention relates to building structures, in particular to a structural self-insulating concrete composite wall panel and a manufacturing method thereof. Background technique [0002] From the point of view of its construction method and current use situation, the commonly used external wall insulation system still has the following problems: [0003] 1) The external thermal insulation system of the external wall is constructed separately from the main structure, prolonging the construction period and increasing the construction cost; the density difference between the thermal insulation layer and other materials is too large, and the elastic modulus and linear expansion coefficient between the materials are also different. There will be relatively large differences in deformation between the lower materials, and it is very easy to produce cracks or even fall off of the surface layer. [0004] 2) There is a cavity between the insulation layer and ...
