Description

Double-side formwork integrated shear wall based on truss reinforcement cage and construction method thereof Technical Field The invention relates to the technical field of shear walls, in particular to a double-side formwork integrated shear wall based on a truss reinforcement cage and a construction method thereof. Background The traditional shear wall construction method generally comprises the links of formwork support, reinforcement bar binding, concrete pouring, formwork removal and the like, and has the problems of multiple working procedures, long construction period, high labor intensity, dependence on manual construction precision and the like. In recent years, a construction method of a shear wall adopting a formwork system is gradually applied, and the formwork is used as a permanent formwork to realize the formwork removal-free construction, so that the construction efficiency is remarkably improved. However, the prior art formwork systems often employ separate connectors or rigid fasteners to connect the two-sided formwork, which has the following drawbacks: 1. the connection stability is not enough, namely, in the concrete pouring process, the double-side shuttering is positioned only by virtue of the point-shaped connecting pieces, the integral rigidity cannot be formed, and the double-side shuttering is easy to deform due to pouring pressure. 2. The reinforcement cage has strong independence, the reinforcement cage is installed and separated from the formwork in the existing formwork system, the construction links are increased, and the integrity is insufficient. 3. The adjustment capability is poor, and the traditional method can not realize the integrated positioning of the double-side shuttering and the steel reinforcement framework, and the control of the thickness and the verticality of the wall is affected. Disclosure of Invention In order to overcome the defects existing in the prior art, the invention provides a double-side formwork integrated shear wall based on a truss reinforcement cage and a construction method thereof, so as to solve the problem of insufficient connection stability of the shear wall of the traditional formwork system. To achieve the above object, a double-sided formwork integrated shear wall based on truss reinforcement cage is provided, comprising: the two mould shell plates are oppositely arranged; The truss framework units are arranged between the two formwork plates and comprise a central connecting rod and four spoke ribs, the spoke ribs are wavy, the bottoms of the valleys on one side of each spoke rib are connected with the central connecting rod, the four spoke ribs are arranged along the circumferential direction of the central connecting rod, the peak tops on the other side of each spoke rib are buried in the formwork plates, and the middle parts of the spoke ribs are connected with lateral ribs; the connecting ribs are connected with lateral ribs of a plurality of truss framework units; Cast-in-place concrete is poured between the two mould shell plates and is coated on the truss framework units and the connecting ribs.
