Supporting system at position of post-pouring belt of underground garage roof and construction method

Abstract

The invention relates to a supporting system at the position of a post-pouring belt of an underground garage roof and a construction method. The supporting system comprises a garage bottom plate, the garage roof and constructional columns. The post-pouring belt is reserved on the garage roof. The two rows of constructional columns are symmetrically installed on the portions, on the left side and the right side of the post-pouring belt, between the garage bottom plate and the garage roof. Pouring is conducted on the constructional columns, the garage bottom plate and the garage roof together for forming. According to the supporting system, the constructional columns are used as supporting formworks of a post-pouring belt formwork, pouring is conducted on the constructional columns, the garage bottom plate and the garage roof together, construction is easy, the turnover rate of the supporting system is increased, and by arranging the constructional columns, stability of a garage is effectively improved. The post-pouring belt subjected to pouring through the supporting system is high in quality and free of impurities, does not need subsequent processing and saves manpower. The construction method is simple, scientific and reasonable in design and easy to achieve, manpower is effectively saved, the turnover rate of the formworks is increased, the stability of the whole garage is effectively improved by additionally arranging the constructional columns, and the wide application and popularization value is achieved.

Description

technical field [0001] The invention belongs to the field of construction, in particular to a support system and a construction method at the post-cast belt of the roof of an underground garage. Background technique [0002] During the construction of the roof of the underground garage, when the formwork is supported at the post-cast belt of the underground garage roof, steel pipes and fasteners are usually used to set up an independent formwork support system for the post-cast belt, which is erected together with the main frame. [0003] Since the concrete at the post-casting zone of the roof is generally required to be poured 60 days after the completion of the main structure, part of the frame of the post-casting zone cannot be disassembled when the main formwork is removed. [0004] This formwork support system has steel pipes and fasteners that take up turnover, and it is difficult to clean up debris such as garbage gathered at the post-casting belt during the construct...
