逆作法中的大跨度拱形钢桁架转换层结构的施工技术

Construction Technique of Long Span Steel Arch Trussed Transition Story in Reverse Building Method

广州名盛广场工程,采用全逆作法施工钢结构设计方案,并且将路桥工程采用的大跨度拱形钢桁架结构应用于房建工程的转换层结构,这是一种新的尝试。如何将路桥工程的拱形桁架结构施工技术与房建工程的框架结构施工技术有机地结合起来,是本文要着重介绍的内容。

Design scheme of steel structure of re verse building method is adopted in the Guangzhou Mingsheng Square Project, long span steel arch truss structure is applied to transition story in building engineering, which is a new try. This paper will intensively introduce how to organize such a new structural construction, and how to fall the arch trussed structure construction technique of road and bridge engineering and the frame structure construction technique of building engineering together.
