Pre-sealing construction method for basement roof settlement post-cast strip
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.
本发明属于建筑工程建设领域，具体涉及一种地下室顶板沉降后浇带预封闭施工方法；后浇带两侧的结构顶板的支撑体系包括脚手架模板支撑体系和支撑柱支撑体系组成；待结构顶板砼浇筑达到强度后将脚手架模板支撑体系拆除，采用支撑钢板满铺后浇带，在后浇带的中线上间隔布置灌浆钢管，灌浆钢管的顶部管口上点焊固定封板，后浇带区域做防水处理；待主体结构施工完成后，搭设后浇带部位的模板支撑体系，将封板去除通过灌浆钢管进行后浇带灌浆；待后浇带混凝土强度达到设计要求后，将后浇带两侧的支撑柱支撑体系拆除。本发明提供的一种地下室顶板沉降后浇带预封闭施工方法，能够降低工程造价、缩短施工工期、同时满足后浇带两侧结构的安全性和稳定性。
