Reinforced-truss concrete precast panel, reinforced-truss concrete precast panel structure system and construction method thereof

Abstract

The invention discloses a reinforced-truss concrete precast panel, a reinforced-truss concrete precast panel structure system and a construction method thereof. The precast panel comprises panel concrete having a reinforced-truss framework and cast outside the reinforced-truss framework; the reinforced-truss framework comprises an upper-string reinforcement cage, a lower-string reinforcement cage and a vertical reinforcement cage connected between two ends of the upper-string reinforcement cage and the lower-string reinforcement cage; an oblique reinforcing rebar is further arranged in a frame enclosed by the upper-string reinforcement cage, the lower-ring reinforcement cage and the vertical reinforcement cage; the oblique reinforcing rebar is formed by bundle of bars or a reinforcement cage; first connecting plates are embedded in peripheral sides of the reinforced-truss concrete precast panel; the first connecting plates are arranged along the axial direction of the side face of the reinforced-truss concrete precast panel. By the arrangement, technical problems that framework engineering quantity is large, construction is difficult, building layout cannot be flexibly cooperated, construction period is long and late demolition is difficult in construction of shear walls in a traditional structure system are solved.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a reinforced truss concrete prefabricated wall panel, a structural system and a construction method thereof. Background technique [0002] Frame-tube structure, frame-shear structure and shear wall structure are the structural forms commonly used in the design of contemporary high-rise buildings. In order to make these building structures have sufficient rigidity, a certain number of shear walls will be arranged in the design structure. A sufficient number of Shear walls impart considerable rigidity to the building itself. At present, the commonly used shear wall is cast-in-place together with the structural frame as a whole. This structure has the following disadvantages: 1. The amount of formwork is large, and the on-site construction is difficult, resulting in high project cost; 2. It cannot be flexibly matched with the building layout, which is not...
