Tool type structure construction joint rapid retaining construction method

Abstract

The invention relates to a tool type structure construction joint rapid reserving construction method. The tool type structure construction joint rapid reserving construction method is applied to the field of concrete construction joint reserving construction. The tool type structure construction joint rapid reserving construction method comprises the following steps that S1, a construction joint reserving position is determined; S2, a reinforcing mesh is bound; S3, after binding of the reinforcing mesh is completed, a steel formwork stopper is installed along a construction joint, the steel formwork stopper is perpendicularly inserted into the reinforcing mesh, and reinforcing steel bars can penetrate through reinforcing steel bar installing notches in the steel formwork stopper; S4, fixing supporting legs on the steel formwork stopper are connected to a floor slab bottom formwork through self-tapping screws, and the steel formwork stopper is fixed; S5, the reinforcing steel bar installing notches are sealed by using a slurry leakage prevention formwork; S6, concrete is poured; and S7, after the concrete is finally set for about 12 hours, the steel formwork stopper is dismantled, and construction joint reserving is completed. The tool type structure construction joint rapid reserving construction method has the effects that the construction joint retaining construction process is easy and fast to operate, the construction quality is guaranteed, the construction efficiency is high, and the problems of uneven construction joints, steel bar deviation, slurry leakage and the like are not prone to occurring.

Description

technical field [0001] The present application relates to the field of construction of concrete construction joints, and in particular to a method for fast construction of construction joints of a tool-type structure. Background technique [0002] Construction joints refer to the joints formed between the first and last poured concrete due to design requirements or construction needs to be poured in sections during the concrete pouring process. The construction joint is not a real joint, it is just because the concrete poured first exceeds the initial setting time, and there is a joint surface with the concrete poured later, which is called the construction joint. [0003] As a special process joint, the construction joint cannot be continuously poured due to the influence of the construction process, such as the installation of upper steel bars, re-installation of formwork and scaffolding and other objective reasons, or subjective reasons such as workers changing shifts, se...
