大管径多管组拼式树杈柱施工技术

Construction Technology of Large-diameter Multi-pipe Combination Tree Branch Column

介绍了大管径树杈柱的制作安装工艺。采用组拼构件垂直拼装,利于分叉端朝向的精度控制。采用工具式支架、承插式定位系统等辅助工具,使构件定位更精确、成型更便捷,最大程度上缩短了制作工期,增加了制作经济效益。采用耳板临时固定,精确定位、放置基础预埋件。并用螺栓临时固定树杈上部直段圆管,有效保证了安装效果。

This paper introduces the fabrication and installation technology of large diameter tree branch column.The vertical assembly is adopted to control the precision of bifurcation end orientation.The auxiliary tools such as tool bracket and socket positioning system are adopted to make the component positioning more accurate and the forming more convenient,shorten the production period to the greatest extent,and increase the economic benefits of the production.The ear-plate is adopted for temporary fixation,accurate positioning and placement of foundation embedded parts.Bolt is used to temporarily fix the straight round pipe on the upper part of the tree branch to ensure the installation effect effectively.
