摘要
一般预埋大型钢结构构件通常是先进行预埋件定位安装再进行钢筋绑扎等后续工序。上海世茂深坑酒店坑顶大梁上的28个主楼钢结构桁架支座预埋件结构相当复杂,如果先进行预埋件的安装,将使得后续的钢筋绑扎、螺旋箍安装和预应力锚索的定位加固变得困难。因此,坑顶大梁的桁架支座预埋件施工采用后安置法,实际工程中效果良好。
Generally, pre-buried large steel structural members which are usually firstly installed of embedded parts positioning rebar and other follow-up processes. The 28 main girder steel structure truss support structures are quite complex embedded parts of Shanghai Shimao Chasm Hotel. If the embedded parts were installed firstly, the positioning of subsequent reinforcement assembling, installation and spiral hoop prestressed anchor cable reinforcement becomes difficult. The roof truss support embedded parts of the girder was constructed after placement, and the practical engineering effect is good
