摘　　要：国家会展中心(天津)一期工程交通连廊内框架钢柱与基础连接位置考虑筏板、承台一次性浇筑的特殊性,常规地脚螺栓连接方式不满足现场施工要求。针对在安装柱脚时无法保证水平位置精度,且在遇到轴线位移有问题时无法对支架进行灵活调整,使浇筑后的柱脚上端水平高度不一致,造成水平方向倾斜、受力不均匀等问题,采用"支架+钢柱+定位装置"预埋柱脚施工方法满足现场施工要求,达到快速定位、便捷安装的效果。Considering the particularity of one-time pouring of raft and bearing platform,the connection position between steel column and foundation in traffic corridor in the first phase project of National Convention and Exhibition Center(Tianjin) does not meet the requirements of site construction.In view of the fact that the accuracy of the horizontal position cannot be guaranteed when the column base is installed,and the support can not be flexibly adjusted in case of axis displacement problems,resulting in problems such as horizontal inclination and uneven stress after pouring,the construction method of bracket + steel column + positioning device is adopted to embedded the column base to meet the requirements of site construction,achieving the effect of rapid positioning and convenient installation.
