Construction method for basement buttress stirrups and steel plate waterstops

Abstract

The invention provides a construction method of basement buttress stirrups and a steel plate water-stop belt, and belongs to the technical field of building construction, and the construction method comprises the following steps: S1, firstly constructing basement bottom plate reinforcing steel bars, retaining wall reinforcing steel bars, buttress longitudinal bars and the buttress stirrups below the bottom edge of the steel plate water-stop belt; s2, mounting a steel plate water stop belt; s3, a buttress stirrup conflicting with the steel plate water stop belt is installed, and the two ends of the buttress stirrup are in spot welding with the steel plate water stop belt at the position where the buttress stirrup is cut off by the steel plate water stop belt; s4, buttress stirrups are installed above the top edge of the steel plate water stop belt; s5, the transverse stirrups continue to be installed above the buttress stirrups; and S6, after the formwork is installed, concrete pouring and curing are conducted in sequence, and concrete is formed. According to the construction method of the basement buttress stirrup and the steel plate water-stop belt, the waterproof and leakage-stopping effects of the steel plate water-stop belt are not affected, the adverse effect on the stress condition of the buttress is avoided, and the construction cost and steps are not increased too much.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a basement buttress column stirrup and a steel plate waterstop. Background technique [0002] At present, there are two common construction methods for the stirrups of the existing buttress columns. One is to cancel or truncate the stirrups that conflict with the steel plate waterstop, and no other treatment is required. The bottom of the column is the place where the force is concentrated, and the bending moment and shear force are large. This method is unfavorable to the force of the column. The second is to increase the column section, and the steel plate waterstop is bent and bypassed from the outside of the buttress column steel bars. This method increases the cross-section of the column, increases the amount of concrete, and the outer protective layer of steel bars is thicker. In order to prevent cracking, the amount of steel bars nee...

AI Technical Summary

Problems solved by technology

This method increases the section of the column, increases the amount of concrete, and the protective layer of the outer reinforcement is too thick. In order to prevent cracking, the amount of reinforcement needs to be increased. The cost increases, and the construction is inconvenient and the construction steps are more complicated.
