Abstract

The invention discloses a structure and energy conservation integrated assembly type prefabricated external wall panel and a preparation method. The structure and energy conservation integrated assembly type prefabricated external wall panel comprises a prefabricated external wall panel body. The prefabricated external wall panel body comprises lightweight aggregate concrete surface layers, a rigid foaming polyurethane sandwich layer, and a steel mesh frame. Six external layers of the prefabricated external wall panel body are all lightweight aggregate concrete surface layers. The steel mesh frame is a square frame. Six mesh frame surfaces of the steel mesh frame are all correspondingly poured into the six lightweight aggregate concrete surface layers. The rigid foaming polyurethane sandwich layer is filled into a cavity enclosed by the six lightweight aggregate concrete surface layers. The concrete layers and the PU heat-insulation layer are firmly combined together through rough surfaces of the lightweight aggregate concrete surface layers, steel truss connectors, and self adhesion stress of the polyurethane, cooperative work of profile layers of the wall panel is ensured, and insulation and structure are integrated. The wall body and insulation are industrializedly produced and constructed simultaneously, and construction processes are simplified.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an assembled prefabricated exterior wall panel integrated with structure and energy saving and a preparation method thereof. Background technique [0002] my country is in an important stage of accelerated development of industrialization and urbanization. It is a stage where the contradiction between environmental constraints and rapid economic and social development is prominent. The form of energy conservation and emission reduction is severe. The traditional construction industry has problems such as large energy consumption and large disturbance to the environment. Therefore, since 2013, my country has successively issued documents such as the "Green Building Action Plan" and "Several Opinions on Promoting the Development and Reform of the Construction Industry", calling for green and energy-saving buildings as the main purpose and prefabricated buildings as the main p...
