Fabricated shear wall lateral steel bar connecting device and application method thereof

Abstract

The invention discloses a fabricated shear wall lateral steel bar connecting device and an application method thereof. The fabricated shear wall lateral steel bar connecting device comprises H-shaped steel, wherein U-shaped grooves are formed in the two ends of a side plate of the H-shaped steel respectively, horizontal reserved steel bars penetrate into the U-shaped grooves from prefabricated shear wall bodies on the two sides separately and are in threaded connection to high-strength nuts on the inner side wall of the H-shaped steel, steel rod reserved holes are formed in notches of the U-shaped grooves and in the side plate of the H-shaped steel, the steel rod is inserted into the steel rod reserved holes in a matched manner, and longitudinal reserved steel bars of a lower wall body penetrate through included angles formed by the two ends of the outer side wall of the H-shaped steel and the horizontal reserved steel bars and are fixedly connected to the horizontal reserved steel bars. Prefabricated shear walls are hoisted from the upper portion of the longitudinal reserved steel bars from top to bottom, the H-shaped steel, the horizontal reserved steel bars and the longitudinal reserved steel bars are assembled and connected to form a whole after the shear walls are hoisted in place, the shear resistance and the integrity of the wall bodies are enhanced, stirrups at connecting positions are replaced with the H-shaped steel, binding with the stirrups is reduced, the hoisting efficiency is improved, the construction difficulty is reduced, and the device has the advantages of simple structure, strong shear resistance, good integrity, practicability and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of prefabricated shear wall connection, and in particular relates to a lateral reinforcement connection device and application method of a prefabricated shear wall. Background technique [0002] With the country's vigorous promotion of prefabricated shear walls, various localities and enterprises have actively responded and implemented them, with remarkable results; at the same time, problems are also prominent during the on-site hoisting of prefabricated shear walls. In the general prefabricated shear wall structure, the post-cast concrete structure is used to connect the prefabricated walls, so the prefabricated walls will reserve steel bars on the side of the wall, and the steel bars are generally in the form of U-shaped steel bars, 90° hooks and 180° Structural forms such as hooks. The lateral reserved steel bars of the prefabricated shear wall and the reserved longitudinal steel bars of the cast-in-pla...

AI Technical Summary

Problems solved by technology

The laterally reserved steel bars of the prefabricated shear wall and the longitudinal steel bars reserved for the cast-in-place part of the lower floor are prone to "fighting" of the steel bars during the hoisting process, which affects the construction process and reduces the hoisting efficiency of the shear wall

[0003] One of the existing solutions is to improve the order and method of hoisting without changing the reserved form of the lateral reinforcement of the wall. First, accurately locate the reserved reinforcement and hoist from top to bottom. There is an elbow at the end of the reserved steel bar, which still cannot avoid interference with the reserved longitudinal steel bar, which affects the hoisting efficiency; the other is to pull and bend the reserved longitudinal steel bar, which meets the hoisting requirements, but Seriously affect the mechanical properties of steel bars
