| 摘 要： | 本文介绍一种全新的转换粱支撑系统的施工方法，避免了支撑系统采用垂直支撑系统设计，利用转换层以下楼地面结构承受施工荷载．而采用扣件式钢管将支撑系统设计成平行弦桁架支撑系统施工作业，施工荷载由转换层以下的柱等竖向构件承担，不利用转换层以下楼地面结构承受施工荷载．经济合理地完成了转换梁的施工作业。

| Abstract: | This article introduced a new construction method for transfer girder supporting system, which uses the fastener-style steel pipe paralled-chord truss instead of the vertical supporting system, and the construction load is carried by vertical members as columns below the transfer girder rather than the floor structures, thus can accomplish the transfer girder construction economically. |
