Pre-sealing construction method for basement roof settlement post-cast strip

Abstract

The invention belongs to the field of constructional engineering construction, and particularly relates to a basement roof settlement post-cast strip pre-sealing construction method. The supporting system of the structural top plates on the two sides of the post-cast strip comprises a scaffold formwork supporting system and a supporting column supporting system. After structural top plate concrete pouring reaches the strength, a scaffold formwork supporting system is dismantled, a post-cast strip is fully laid through supporting steel plates, grouting steel pipes are arranged on the middle line of the post-cast strip at intervals, sealing plates are fixed to top pipe openings of the grouting steel pipes in a spot welding mode, and waterproof treatment is conducted on the post-cast strip area; after construction of the main body structure is completed, a formwork supporting system of the post-cast strip part is erected, the sealing plate is removed, and post-cast strip grouting is conducted through the grouting steel pipe; and after the concrete strength of the post-cast strip meets the design requirement, the supporting column supporting systems on the two sides of the post-cast strip are dismantled. According to the pre-sealing construction method for the basement roof settlement post-cast strip, the construction cost can be reduced, the construction period can be shortened, and meanwhile the safety and stability of structures on the two sides of the post-cast strip are met.

Description

technical field [0001] The invention belongs to the field of building engineering construction, and in particular relates to a pre-sealing construction method for pouring belts after basement roof settlement. Background technique [0002] In recent years, the rapid development of my country's construction industry has made great contributions to the country's economic and social development, driving the rolling development of multiple industrial chains. At the same time, most real estate developers pursue a high-turnover development strategy to achieve marketing goals and a good environment for customers to purchase houses early. Construction units need to cooperate with owners in the project sales model display and garden display during the construction process. There is often an upper body of the main building.

At the same time, most real estate developers pursue a high-turnover development strategy to achieve marketing goals and a good environment for customers to purchase houses early. Construction units need to cooperate with owners in the project sales model display and garden display during the construction process. There is often an upper body of the main building. Before the construction is completed, it is necessary to cooperate with the construction unit to construct the surrounding basement roof, garden landscape display, etc. However, the post-pouring belt of the basement roof cannot be directly poured because the settlement of the surrounding buildings is not stable.

[0003] The post-settlement pouring zone between the main building and the surrounding basement can only be constructed after the main structure of the main building is capped and the settlement is stable. Due to the setting of the post-casting zone, the stress state of the original structure is temporarily changed. Generally, the two sides of the post-casting zone Formwork and its steel pipe supports are not dismantled in principle, but considering the long-term occupation of turnover materials such as formwork, steel pipes and fasteners, they cannot be effectively used, which increases the cost
