Longitudinal bar bundled pouring long through hole pre-cast shear wall and construction method thereof

Abstract

The invention discloses a longitudinal bar bundled pouring long through hole pre-cast shear wall and a construction method thereof, and relates to a pre-cast shear wall vertical connection method so as to solve the problems that according to nodular cast iron grouting sleeve connection, semi-grouting sleeve connection and constraint slurry anchor lap joint of a shear wall, the manufacturing cost is high, the connection workload is large, and the assembling construction progress is slow. The shear wall comprises N layers of precast shear wall bodies, M layers of precast stacked ribbed floor base plates, a plurality of sets of bundling longitudinal bars and concrete; every two adjacent layers of precast shear wall bodies are vertically arranged in an aligned mode, the bundling longitudinal bars are arranged inside N vertically and coaxially arranged bundling long through holes respectively, and concrete is poured into gaps among the precast stacked ribbed floor base plates and the two adjacent layers of precast shear wall bodies. The method comprises the main steps of manufacturing the N layers of precast shear wall bodies and the M layers of precast stacked ribbed floor base plates, arranging the precast stacked ribbed floor base plates, pouring concrete, and completing construction of the longitudinal bar bundled pouring long through hole pre-cast shear wall. The longitudinal bar bundled pouring long through hole pre-cast shear wall is used for precast shear wall vertical connection.

Description

technical field [0001] The invention relates to a vertical connection method of a prefabricated shear wall in the field of civil engineering, in particular to a prefabricated shear wall in which long holes are filled after the longitudinal reinforcement is bundled, and a vertical connection construction method thereof. Background technique [0002] At present, the method developed by Japan using nodular cast iron grouting sleeves to connect vertical longitudinal reinforcements in shear walls at the floor elevation is safe and reliable, but the cost is high, the connection workload is heavy, and the assembly construction progress is slow; my country's nodular iron grouting sleeves in Japan The semi-grouting sleeve connection (one end of the sleeve is bolted and the other end adopts the same grouting connection as in Japan) and the restrained grout anchor lap connection developed on the basis of the sleeve connection technology have reduced the cost, but there are still connecti...
