A method for installing vertical splicing joints of steel plate concrete shear walls

Abstract

The invention discloses an installation method for vertical splice joints of steel plate concrete reinforced concrete shear walls. The installation method includes the following steps that (1) the steel plate reinforced concrete shear walls, steel plate reinforced concrete shear wall end posts, splice joint end heads and shear resistance tension parts are separately prefabricated in a factory; (2)splice joint end heads are welded to the upper and lower ends of the steel plate concrete reinforced concrete shear wall end posts separately; (3) the steel plate concrete reinforced concrete shear wall end posts with the splice joint end heads in a welded mode are welded to the left and right sides of each steel plate reinforced concrete shear wall separately to form connecting walls; (4) the lower piece connecting walls are hoisted to the preset positions to be vertical; and (5) upper piece connecting walls and the lower piece connecting walls are connected. The installation method for thevertical splice joints of the steel plate concrete reinforced concrete shear walls has the advantages of shearing resistance and tension resistance and reliable force transferring, and can bear high tension and shear force load.

Description

technical field [0001] The invention relates to a vertical splicing node of an assembled prefabricated steel plate concrete shear wall end column, in particular to a method for installing a vertical splicing node of a steel plate concrete shear wall. Background technique [0002] Under the background of creating a "resource-saving and environment-friendly" society, the steel plate concrete shear wall has high bearing capacity, good ductility and stable hysteretic performance. Compared with the traditional concrete shear wall, no formwork is required , The construction speed is fast and the wall is thin, which can effectively reduce the self-weight of the structure to a certain extent. [0003] The steel plate concrete shear wall with end columns is the most common form of steel plate concrete shear wall. Since the steel plate concrete shear wall mainly considers the force in its plane, combined with its structural characteristics, the horizontal load can be applied to the pl...

AI Technical Summary

Problems solved by technology

[0005] (1) Splicing is carried out by reserving grouting holes and extending steel bars, which still requires wet construction, and the controllability of splicing quality is weak after a long time

[0006] (2) The end of the column is provided with an end plate that is spliced ​​by bolts, the production and processing are complicated, and the end plate affects the use of the building

[0007] (3) The prefabricated extension members at the end of the column are spliced ​​by welding, which requires the use of open flames, which increases the difficulty and risk of construction, and the weld quality is less controllable
