Problems solved by technology

[0003] In the turning stairwell, the concrete wall panel formwork is manufactured and installed. The traditional method is to support the formwork until it is disconnected at the structural slab level. Defects, stairs are an important part of the anti-seismic fortification of frame and shear wall structures and the focus of quality inspection. The quality of project perception is the key to reducing repair costs and improving project quality. Therefore, the present invention proposes a turning type stairwell formwork The construction method of one-time molding and pouring in batches to solve the problems in the prior art

Embodiment 1

[0029] according to Figure 1-Figure 2 As shown, the present embodiment proposes a construction method for one-time forming and sub-casting of a turning-type stairwell formwork, comprising the following steps:

[0030] Step 1. Rebar binding

[0031] First, tie the steel bars of the floors and beams, and then position the steel bars of the stairwell wall panels. After the steel bars are positioned, the steel bars of the stairwell wall columns are bound. After the steel bar binding operation is completed, it is checked and accepted. , For the unqualified part, it needs to be re-bundled until it is qualified. Before the acceptance of the steel bar binding, it is necessary to deal with the construction joint of the wall, rinse it after treatment, and then accept it. The treatment is done within 3mm of the wall column edge Play another cutting line, cut with a toothless saw, the cutting depth is 10mm, after the cutting is completed, remove the weak layer of the horizontal construc...

Embodiment 2

[0043] according to image 3 As shown in the figure, the present embodiment proposes a construction method of one-time molding and staged pouring of a turning-type stairwell formwork, step 1, reinforcing steel bar binding

[0044] First, tie the steel bars of the floors and beams, and then position the steel bars of the stairwell wall panels. After the steel bars are positioned, the steel bars of the stairwell wall columns are bound. After the steel bar binding operation is completed, it is checked and accepted. , For the unqualified part, it needs to be re-bundled until it is qualified. Before the acceptance of the steel bar binding, it is necessary to deal with the construction joint of the wall, rinse it after treatment, and then accept it. The treatment is done within 3mm of the wall column edge Play another cutting line, cut with a toothless saw, the cutting depth is 10mm, after the cutting is completed, remove the weak layer of the horizontal construction mortar, expose ...

Abstract

The invention provides a turning type staircase formwork one-time forming and multi-time pouring construction method which comprises the five steps of steel bar binding, wall column formwork installation, supporting system installation, concrete pouring and formwork dismantling. The turning type staircase formwork one-time forming and multi-time pouring construction method adopts a one-time forming and multi-time pouring mode; the common quality problems of slab staggering, slurry leakage, root rot and the like of the concrete shear wall are effectively solved, the concrete appearance quality is improved, meanwhile, in the concrete pouring process, the slurry leakage phenomenon in the concrete pouring process can be avoided, the material cleaning work is omitted, meanwhile, the procedure of correcting the wall foot formwork is omitted in the next concrete pouring process, the construction progress is accelerated, and the construction cost is reduced. And the staircase formwork is easy and convenient to install, after the staircase formwork is dismantled, the shear wall joint does not need to be chiseled and repaired, labor is saved, and therefore the installation construction efficiency of the staircase inner formwork is improved, the main body construction quality in the staircase is guaranteed, and the construction cost is saved to a certain degree.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for one-time forming and staged pouring of a turning-type stairwell formwork. Background technique [0002] Stairwell refers to a space occupied by stairs. It is divided into open stairwell, turning stairwell, closed stairwell and smoke-proof stairwell. It is widely found in industrial and civil buildings. , built for the actual needs of life, as a hub connecting up and down traffic. Most places that need stairs have stairwells, but in a few cases, they will not be built, such as outdoor steel-frame stairs; [0003] In the turning-type stairwell, the concrete wall panel formwork is produced and installed. The traditional method is to support the formwork to be disconnected at the level of the structural slab. This kind of process construction is easy to produce quality such as misplacement, leakage of slurry, and rotten roots at the joints ...
