| 摘 要： | 厦门海峡交流中心二期工程1号楼巨型插入式钢柱脚伸入混凝土底板内2m,并下设8根0.6m长的锚栓,施工分螺栓预埋和柱脚安装两步,且与底板混凝土两次浇筑穿插施工,混凝土浇筑对柱脚安装精度影响最大,现场制作限位板与锚栓成组整体预埋并与底板钢筋刚接形成稳固结构削弱影响,还采取钢筋点焊加固及导链和钢筋拉杆组合加固措施以削弱混凝土施工的不利影响,有效保证了埋入式巨型钢柱脚的安装精度。

| Abstract: | The giant embedded steel column foot of Xiamen Strait Exchange Center No.1 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 combined 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-rod.All these measures we took effectively guarantee the installation accuracy. |
