Building thermal-insulation wallboard

Abstract

The invention provides a building thermal-insulation wallboard. The building thermal-insulation wallboard comprises an outdoor surface concrete layer, an indoor surface concrete layer and a steel wire gauze framework, wherein one side of the steel wire gauze framework is fixedly connected with the outdoor surface concrete layer; the other side of the steel wire gauze framework is connected with the indoor surface concrete layer; an external thermal-insulation layer is fixedly connected inside the outdoor surface concrete layer; an internal thermal-insulation layer is fixedly connected outside the indoor surface concrete layer; an air spacing layer is arranged between the external thermal-insulation layer and the internal thermal-insulation layer. The building thermal-insulation wallboard disclosed by the invention has the beneficial effect as follows: the building thermal-insulation wallboard has the advantages that structure is simple, air is sufficiently utilized as the thermal-insulation layer, a great deal of energy resources are saved, cost is low, thermal-insulation and heat insulation effect is good, duration of a period is greatly shortened, thermal-insulation service life can be as long as service life of the building, and structural performance requirements of high shock resistance and strong air pressure resistance are satisfied.

Description

Technical field [0001] The invention belongs to the field of exterior wall panels used in construction projects, and particularly relates to a building thermal insulation wall panel. Background technique [0002] At present, domestic construction engineering thermal insulation is mainly based on self-insulating blocks and composite insulation on the base layer. Due to the setting method of the insulation layer and improper material application measures, it has caused some insurmountable problems to the quality of the construction project, especially the insulation life. problem. [0003] There are many types of insulation materials, and their physical properties and methods of use are directly related to the insulation effect and life. The best insulation material should be rigid foam polyurethane, and the thermal conductivity of air under standard conditions is close to rigid foam polyurethane. The air is not fully and scientifically applied to the exterior wall panels. Summary ...

Problems solved by technology

[0002] At present, the thermal insulation of domestic construction projects is mainly based on self-insulation blocks and composite insulation on the base layer. Due to the installation method of the insulation layer and improper material application measures, there are some insurmountable constraints on the quality of construction projects, especially the insulation life. question

[0003] There are many kinds of thermal insulation materials, and their physical properties and usage methods are directly related to the thermal insulation effect and service life. The best thermal insulation material should be rigid foam polyurethane, and the thermal conductivity of air under standard conditions is close to rigid foam polyurethane. At present, there are still The air is not fully scientifically applied to the exterior wall panels
