Longitudinal connection structure for superimposed slab concrete shear walls and connection method

Abstract

The invention provides a longitudinal connection structure for superimposed slab concrete shear walls and a connection method, and solves the problems of a traditional longitudinal connection method for prefabricated part walls that the prefabricated part production process is complicated, field hole aligning is difficult, the loss of a grouting material during field mixing is huge, the grouting material is quick in setting and hardening, and the mixing qualities are much different during mixing. The longitudinal connection structure comprises a closed ring-shaped connecting stirrup (2), the connecting stirrup extends into an upper superimposed slab concrete shear wall (1) and a lower superimposed slab concrete shear wall (1) which are mutually connected to form a transition space together with ring-shaped longitudinal bars (5) of the upper superimposed slab concrete shear wall and the lower superimposed slab concrete shear wall, pin joint longitudinal bars (3) penetrate into the transition space in a manner of being perpendicular to the plane where the connecting stirrup is positioned, and the ring-shaped longitudinal bars of the upper superimposed slab concrete shear wall and the lower superimposed slab concrete shear wall are integrated with the pin joint longitudinal bars. The connection method is applied to the longitudinal connection structure for the superimposed slab concrete shear walls.

Description

[0001] Technical field: [0002] The invention relates to a longitudinal connection structure and connection method of a laminated slab concrete shear wall, which can be widely used in the connection of prefabricated concrete member walls and laminated slab concrete shear walls in building industrialization, and the connection of prefabricated concrete member wall panels and walls. [0003] Background technique: [0004] At present, in the traditional prefabricated member wall longitudinal reinforcement connection methods, the more common methods include sleeve connection, restraint grout anchor lap connection, pre-embedded corrugated pipe grouting anchor connection, etc., including vertical spiral stirrup, core mold tube grouting Connection, the production process of prefabricated components of these connection methods is complicated, it is difficult to make holes on site, the loss of site mixing grouting material is large, the grouting material solidifies and hardens quickly, ...

Problems solved by technology

[0004] At present, in the traditional prefabricated member wall longitudinal reinforcement connection methods, the more common methods include sleeve connection, restraint grout anchor lap connection, pre-embedded corrugated pipe grouting anchor connection, etc., including vertical spiral stirrup, core mold tube grouting Connection, the production process of prefabricated components of these connection methods is complicated, it is difficult to make holes on site, the loss of site mixing grouting material is large, the grouting material solidifies and hardens quickly, and the quality of each mixing is quite different, resulting in waste and pollution to the completed project. Difficult, the quality of grouting cannot be guaranteed; each steel bar requires a lot of repetitive anchoring procedures, which wastes manpower

The construction process is complicated, the factory processing is cumbersome, and the on-site installation is difficult.
