Basement floor slab construction method based on stand column assembly type fixing
The invention relates to the technical field of foundation pit supporting engineering, and discloses a basement floor slab construction method based on stand column assembly type fixing, which specifically comprises the following steps: S1, constructing a supporting pile, a stand column and a supporting beam according to the requirements of a design drawing, and excavating a foundation pit to a pit bottom; and S2, a basement bottom plate, a basement outer wall and the bottommost floor are sequentially constructed, the hole space of the fabricated fixing device is reserved in the bottommost floor, concrete is poured into the floor outside the reserved hole, and after the fabricated fixing device is installed in the range of the reserved hole, the supporting beam on the bottommost floor is dismantled. Temporary constraint is arranged at the position of the floor, constraint of a supporting beam before support dismounting is replaced, after the supporting beam is dismounted, the stability and bearing capacity of the stand column can be effectively guaranteed, the construction gap between the stand column and the floor is effectively filled, reliable constraint is provided, meanwhile, rectangular or circular stand column grooves can be prefabricated, and the construction efficiency is improved. The cross section forms of rectangular stand columns, circular stand columns and the like can be used, and therefore the practicability of the assembly type fixing device is improved.
本发明涉及基坑支护工程的技术领域，公开了基于立柱装配式固定的地下室楼板施工方法，具体包括如下步骤：S1：按照设计图纸要求施工支护桩、立柱、支撑梁，基坑开挖至坑底；S2：依次施工地下室底板、地下室外墙、最底层楼板，最底层楼板预留装配式固定装置孔洞空间，预留孔洞以外的楼板浇筑混凝土，预留孔洞范围安装装配式固定装置后拆除最底层楼板上的支撑梁。本发明通过在楼板处设置临时约束，代替了拆撑前支撑梁的约束，在拆除支撑梁后能有效保证立柱的稳定性及承载力，有效填充立柱与楼板之间的施工空隙，提供可靠的约束，同时可以预制呈矩形状或圆形状的立柱槽，可使用矩形立柱、圆形立柱等截面形式，从而提升了装配式固定装置的实用性。
