Assembly type reinforced concrete wall structure based on thermal bridge partition technology

Abstract

The invention provides an assembly type reinforced concrete wall structure based on the thermal bridge partition technology. The assembly type reinforced concrete wall structure comprises an exterior wall panel, a wall panel intermediate layer, an interior wall panel and trusses. A wall is of a sandwich structure formed by the exterior wall panel, the wall panel intermediate layer and the interior wall panel from outside to inside. Chord members of the trusses are embedded in the exterior wall panel and the interior wall panel correspondingly. Web members of the trusses penetrate through the wall panel intermediate layer, and the two ends of the web members are connected with chord members of the exterior wall panel and chord members of the interior wall panel correspondingly. The web member of each truss is provided with a web member connecting part used for cutting off a thermal bridge between the exterior wall panel and the interior wall panel. The assembly type reinforced concrete wall structure based on the thermal bridge partition technology has the advantages of being capable of cutting off the thermal bridge, integral in structure and function, good in integrity and the like, overcomes the defects of an existing assembly type concrete wall panel system and has good economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of building wall structures, in particular to an assembled reinforced concrete wall structure based on thermal bridge isolation technology. Background technique [0002] The total energy consumption of buildings accounts for a relatively large proportion in the national economy, and the operational energy consumption of buildings in the use phase is the largest part of the total energy consumption of buildings. Due to the discontinuity of material thermal properties, material non-uniformity, geometric conditions, etc., some parts become areas with relatively dense heat flow and low (or high) inner surface temperature. This area has obvious multi-dimensional heat conduction. The characteristic thermal bridge—the main channel of heat exchange; the existence of the thermal bridge increases the local heat transfer of the wall, reduces the average thermal resistance of the building, increases the energy consumpti...

AI Technical Summary

Problems solved by technology

[0004] In view of the defects existing in the prior art, the purpose of the present invention is to provide a prefabricated reinforced concrete wall based on thermal bridge isolation technology with the advantages of insulating thermal bridges, integrating structure and function, and good integrity, so as to solve the existing problems. The thermal bridge problem of the traditional wall faced by the prefabricated assembly wall, the existing prefabricated concrete wall technology cannot eliminate the secondary problems caused by the thermal bridge, thus limiting the technical problem of its application range
