Prestressed prefabricated concrete shear wall system and construction method thereof

Abstract

The invention provides a prestressed prefabricated concrete shear wall system and a construction method thereof. The prestressed prefabricated concrete shear wall system comprises prefabricated shearwalls and prestressed reinforcements; the transversely adjacent prefabricated shear walls are connected with each other through tongues and grooves; reinforcement through passages are formed in the prefabricated shear walls; anchor bearing plates are buried in positions, corresponding to the reinforcement through passages, at the tops of the prefabricated shear walls; through holes and grout outlets are formed in the anchor bearing plates; gaps are reserved in the bottoms of the prefabricated shear walls; the gaps communicate with the reinforcement through passages; the prestressed reinforcements penetrate through the reinforcement through passages; a first reinforcement connector at the top of the prefabricated shear wall in the lower layer is correspondingly inserted in the gap of the prefabricated shear wall in the upper layer and is connected with the gap through the first reinforcement connector; the gap is filled with a filling material; a grouting pipeline is buried in the filling material; and passage grouting materials are poured in the reinforcement through passages. According to the prestressed prefabricated concrete shear wall system and the construction method thereof,the technical problems of high making accuracy requirement, high quality control difficulty, lack of effective grouting quality detection means, difficult member transportation, multiple site wet operations and longer construction period of a traditional prefabricated shear wall are solved.

Description

technical field [0001] The invention belongs to the field of construction engineering, in particular to a prestressed assembled concrete shear wall system and a construction method thereof. Background technique [0002] The prefabricated concrete structure is one of the important structural systems to realize the modernization of the construction industry. The prefabricated construction method is conducive to improving the construction quality and construction efficiency. Concrete shear walls are an important part of lateral force resistance in shear wall structural systems and frame-shear wall structural systems. At present, the common forms of prefabricated shear walls are as follows: 1. Some prefabricated and some cast-in-place Prefabricated shear wall system. At present, the prefabricated shear wall structure system widely used in projects is that the shear wall is prefabricated in the factory, the beard tendons are reserved in the edge component area or node area, and ...
