Prefabricated core column type self-insulating exterior wall plate, connecting structure and construction method thereof

Abstract

The invention relates to a prefabricated core column type self-insulating exterior wall plate, a connecting structure and a construction method thereof. The exterior wall plate comprises a wall body and a connecting piece which is vertically connected with the wall; the wall is formed by combining a reinforced concrete structure layer and a foam concrete insulating layer; the reinforced concrete structure layer comprises a structure layer steel framework and structure layer concrete; the foam concrete insulating layer is made of foam concrete; the structure layer steel framework comprises a core column reinforcement cage and horizontal reinforcing steel bars; each horizontal reinforcing steel bar comprises two long reinforcing steel bars; a wall top connecting piece is inserted in the top of the core column reinforcement cage in an embedded manner; and a wall bottom connecting piece which is used with the wall top connecting piece is inserted in the bottom of the core column reinforcement cage in an embedded manner. By the prefabricated core column type self-insulating exterior wall plate, the degree of industrialization and assembling is improved effectively, the bearing ability, ductility and anti-seismic property of the wall are improved comprehensively, and purposes of integration of structure insulation, reliable connection between an upper wall body and a lower wall body and convenience in mounting are achieved.

Description

technical field [0001] The invention belongs to the field of structural engineering prefabricated components, in particular to a prefabricated core column type self-insulating exterior wall panel, a connection structure and a construction method thereof. Background technique [0002] The prefabricated reinforced concrete shear wall is a good lateral force-resisting member. Although it has high rigidity, its ductility is relatively poor. At the same time, the prefabricated reinforced concrete shear wall itself does not have thermal insulation performance, and subsequent construction requires a wall thermal insulation system. , The construction is cumbersome; and with the passage of time, the insulation layer is easy to be damaged and peeled off from the structural layer, resulting in weakened building insulation performance, and the maintenance of the insulation layer is time-consuming and labor-intensive. In addition, at this stage, the upper and lower connections of prefabr...
