Heat-insulating external wallboard and manufacturing method thereof

Abstract

The invention discloses a heat-insulating external wallboard, which is characterized in that one side of a steel wire rack framework (2) is fixedly connected with an outdoor surface concrete layer (1), and the other side of the steel wire rack framework (2) is fixedly connected with an indoor surface concrete layer (5); the inside of the outdoor surface concrete layer (1) is fixedly connected with a heat insulating layer (3); an air spacing layer (4) is formed between the heat insulating layer (3) and the indoor surface concrete layer (5). The heat-insulating external wallboard is manufactured by adopting the steps of forming the steel wire rack framework, manufacturing the outdoor surface concrete layer, forming the heat insulating layer, manufacturing the indoor surface concrete layer and plugging; therefore, the heat-insulating external wallboard can save a large amount of energy resources, has low cost and good heat insulating effect, can increase the net area and greatly shorten the construction period of the project, has the same heat insulating service life as that of the building, meet the structural performance requirements of high seismic resistance and high wind pressure resistance, can be widely applied to concrete framework structures, steel structures, steel-concrete structures and new rural construction engineering serving as the external wallboard.

Description

Technical field: [0001] The invention relates to an exterior wall panel used in construction engineering and a manufacturing method thereof, in particular to a thermal insulation exterior wall panel provided with an air spacer layer and a manufacturing method thereof. technical background: [0002] According to statistics, the energy consumption of construction projects accounts for more than 30% of the total energy consumption of the society. For this reason, the country puts forward the requirement of achieving 65% energy saving in buildings. 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, some insurmountable problems have arisen in the quality of construction projects, especially the insulation life. . [0003] There are many kinds of thermal insulation materials, and ...

AI Technical Summary

Problems solved by technology

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, some insurmountable problems have arisen in the quality of construction projects, especially the insulation life.

[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 and scientifically applied to the exterior wall panels to form an insulation layer, which does not save a lot of energy resources for the society
