高地震设防烈度地区超高层钢板组合楼板施工技术

SUPER-HIGH STEEL SHEET COMPOSITE FLOOR CONSTRUCTION TECHNIQUE IN AREA WITH HIGH SEISMIC FORTIFICATION INTENSITY

昆明春之眼商业中心项目,主塔楼为超过400 m的超高层建筑,其中主塔避难层采用超厚钢板作为底板,钢板上通过焊接栓钉、角钢和钢筋混凝土更好地连接,通过对钢板组合楼板施工工艺的介绍,对钢板组合楼板的深化设计、加工制作、现场安装等施工工艺加以论述,并对设计、制作、安装要点进行了归纳总结,形成一套系统的施工技术理论。

The main tower of Kunming Eye of Spring Commercial Center is a 400m superhigh building,whose escape floor is made of super-thick steel sheet on which bolt and angle steel are welded to reliably connected with the reinforced concrete.This paper introduced the steel sheet composite floor construction process and discussed the in-depth design,processing and field installation of the steel sheet composite floor.Key points in design,fabrication and installation were summarized to form a set of systematic theory for construction technique.
