Xu Cong' Zhou Peng' (1.China Construction Steel Strueture Co.Lad.Shenzhen Guangdong 518040 China: 2.Wuhan Railway Station Wuhan Hubei 430071.China) Abstract:The giant embedded steel column foot of Xiamen Strait Exchange Center No.I Building sticks 2m in the concrete base and there are eight 0.6m-length anchors on the bottom of the steel column foot. There are two steps for the installation of steel column foot the first step is to embed the eight anchors the second step is to install the steel column foot.After each step the concrete pouring follows which made the greatest influence on installation accuracy.Before installation on-site made location-limited board is bined with the eight anchors into an anchor group to be pre-embedded.The anchor group is fixed with steel bars in the board by spot-welding to a solid structure to weaken the influence.Some reinforcement measures are taken to reduce adverse effect of concrete pouring such as leading chain and steel pull-ro...
