Abstract

The invention is mainly applied to the technical field of building construction and particularly relates to a building deformation joint concrete double-wall synchronous pouring construction method. The method mainly comprises the following steps that firstly, a deformation joint main steel formwork and a deformation joint auxiliary steel formwork are manufactured; secondly, the deformation joint auxiliary steel formwork is hoisted and installed; thirdly, the deformation joint main steel formwork is hoisted and installed; fourthly, the deformation joint main steel formwork and the deformation joint auxiliary steel formwork are corrected and installed; fifthly, full-thread split bolts penetrate in sequence along the deformation joint main steel formwork and the deformation joint auxiliary steel formwork; sixthly, on the sides, to be poured, of deformation joint double walls, PVC bolt casing pipes are arranged on the full-thread split bolts in a sleeving mode; seventhly, deformation joint double-wall steel bars are bound; eighthly, the deformation joint main steel formwork and the deformation joint auxiliary steel formwork are fastened; ninthly, the double walls are poured; tenthly, the deformation joint main steel formwork and the deformation joint auxiliary steel formwork are demounted. The building deformation joint concrete double-wall synchronous pouring construction method is easy and convenient to implement and efficient; materials are saved, multiple times of using can be achieved through one-time processing, and formworks and resources are saved; the quality is high, the steel formworks are used for replacing original wood formworks, extruded joint mortar is avoided, and environment protection is promoted.

Description

technical field [0001] The invention relates to a construction method for synchronous pouring of concrete double walls in building deformation joints, which is mainly used in the technical field of building construction. Background technique [0002] Due to the small width of the deformation joints on both sides of the concrete structure building, it is difficult to only remove the formwork, and it is also very difficult to control the construction quality of the concrete wall. The existing method can only be constructed on one side, and the concrete strength can only be supported after the strength meets the requirements. The wall formwork on the other side seriously affected the progress of the project. In addition, during the construction process, the support formwork is not easy to support, the construction area is small, and the space for workers to operate is small, so it is difficult to ensure the construction quality. The template support system will expand and run ...

[0002] Due to the small width of the deformation joints on both sides of the concrete structure building, it is difficult to only remove the formwork, and it is also very difficult to control the construction quality of the concrete wall. The existing method can only be constructed on one side, and the concrete strength can only be supported after the strength meets the requirements. The formwork for the wall on the other side seriously affected the progress of the project

In addition, during the construction process, the support formwork is not easy to support, the construction area is small, and the space for workers to operate is small, so it is difficult to ensure the construction quality. The formwork support system has the phenomenon of expansion and runout during the pouring of concrete, and the traditional wooden formwork cannot be taken out after construction, which consumes resources. During the turnover process, the wooden formwork is deformed by water, which affects the construction quality of the structure
