Reverse construction method structure construction method suitable for concrete-filled steel tube supporting column
The invention relates to a reverse construction method structure construction method suitable for a concrete-filled steel tube supporting column. The reverse construction method structure construction method comprises the following steps that the initial elevation of the concrete-filled steel tube supporting column is designed in a construction drawing; simulating the earth excavation process of the foundation pit by adopting a numerical value, and predicting the upheaval quantity of the concrete-filled steel tubular column at each position when an interface layer is constructed; according to the predicted upheaval amount, the construction elevation of the concrete-filled steel tube supporting column is set, the construction elevation of the concrete-filled steel tube supporting column at each position is marked in a construction drawing, and the construction elevation = the initial elevation-the upheaval amount; the concrete-filled steel tube supporting columns are arranged according to the construction elevation, and concrete is poured to form a continuous wall; when the foundation pit is excavated to an interface layer, a structural top plate is constructed, and an anti-shearing piece is constructed at the joint of each steel pipe concrete supporting column and the structural beam; earthwork below the interface layer is excavated in a layered mode, meanwhile, an upper structure top plate of the interface layer is constructed, and a foundation slab is constructed when the earthwork is excavated to the elevation of the foundation slab. The method has the effect of reducing the cracking risk of the structural top plate.
本申请涉及一种适用于钢管混凝土支承柱的逆作法结构施工方法，其包括如下步骤：在施工图纸中设计钢管混凝土支承柱的初始标高；采用数值模拟基坑土方开挖过程，预测施工界面层时各个位置钢管混凝土柱的隆起量；根据预测的隆起量，设置钢管混凝土支承柱的施工标高，并在施工图纸中标出各位置所述钢管混凝土支承柱的施工标高，所述施工标高=初始标高‑隆起量；按施工标高布置的钢管混凝土支承柱，并浇筑混凝土形成连续墙；当基坑开挖到界面层时，施工结构顶板，在每个钢管混凝土支承柱与结构梁的连接处施工抗剪件；分层开挖界面层以下土方，同时施工界面层上部结构顶板，当土方开挖到基础底板标高时施工基础底板。本申请具有降低结构顶板开裂风险的效果。
