Precast concrete wall body

Abstract

The invention relates to a precast concrete wall body and belongs to the technical field of precast rebar concrete structural members. The precast concrete wall body comprises a first precast concrete wall slab and a second precast concrete wall slab which are in parallel; the first precast concrete wall slab adopts wet connection and the second precast concrete wall slab adopts dry connection. According to the precast concrete wall body, the industrial level of a building structure is improved, the stress performance is improved, the resources are saved and the precast concrete wall body can be applied to various wall body bearing structures.

Description

technical field [0001] The invention belongs to the technical field of prefabricated reinforced concrete structural components, in particular to a prefabricated concrete wall suitable for assembling integral structures. Background technique [0002] The heat lost by the building envelope accounts for about 40% of the total building heat consumption, so the energy-saving performance of the building envelope should be strengthened. In order to improve the thermal insulation performance of the wall, composite walls are generally used, that is, reinforced concrete load-bearing walls are combined with energy-saving materials. There are three types of internal thermal insulation composite walls, external thermal insulation composite walls and sandwich thermal insulation walls. The sandwich thermal insulation wall body includes an inner wall body, an outer wall body and a thermal insulation material arranged in the middle. The thermal insulation material can be protected from damag...
