Support replacing method for large foundation pit engineering support
The invention relates to the technical field of building construction, in particular to a large foundation pit engineering support replacing method. Comprising the following steps that an inner supporting structure system is erected, and an enclosure body is arranged; steel bars of the bottom plate and the bottom plate support changing body are laid, and a bottom plate post-cast strip is reserved; a first steel force transmission belt is arranged in the bottom plate post-cast strip; integrally pouring and forming the bottom plate and the bottom plate support changing body; pouring and constructing a structural outer wall and a structural main beam; floor reinforcing steel bars and floor force transmission belt reinforcing steel bars are laid, and a floor post-cast strip is reserved; a second steel force transmission belt is arranged in the floor post-cast strip; pouring a floor slab and a floor slab force transmission belt; and the inner supporting structure system is dismantled. According to the support changing method, overall construction is simple, the construction period is shortened, cost is saved, the overall rigidity between support changing and an enclosure body is improved, profile steel can be turned over, and the quality and strength of concrete can be effectively guaranteed; a steel force transmission belt is arranged in the post-cast strip, and the stress can be reasonably transferred and distributed after the support is removed; the floor force transmission belt and the floor are the same in thickness and are integrally poured, and construction is convenient.
本发明涉及建筑施工技术领域，具体为一种大型基坑工程支撑换撑方法；包括以下步骤：搭设内支撑结构体系，并设置围护体；铺设底板与底板换撑体的钢筋，预留底板后浇带；在底板后浇带内设置第一钢传力带；一体浇筑成型底板与底板换撑体；浇筑施工结构外墙与结构主梁；铺设楼板钢筋、楼板传力带钢筋，预留楼板后浇带；在楼板后浇带内设置第二钢传力带；浇筑楼板及楼板传力带；拆除内支撑结构体系。本换撑方法整体施工简单，加快工期，节约成本，提升了换撑和围护体之间的整体刚度，型钢可周转，混凝土质量和强度能够有效保证；后浇带内设置钢传力带，拆除支护后应力能得到合理的转移与分配；楼板传力带与楼板的厚度相同，一体浇筑，施工方便。
