Construction method for mounting vertical shaft air pipe
The invention discloses a construction method for mounting a vertical shaft air pipe. The construction method comprises the steps of segmented construction, fixed-point assembly, unit-by-unit inverted assembly, process hole reservation of a shear wall, addition of a unilateral angle steel inner flange and an access hole in a unit-by-unit butt joint port, and arrangement of a lifting device and a segmented air pipe lifting appliance. The air pipe of each unit is high in three floors, a lifting point of a lifting appliance is arranged at an upper opening of the air pipe, and a lifting device is arranged above a vertical shaft top layer of a high floor. According to the construction method, the air pipes are installed in a sectional and unit inversion mode, a large amount of labor and installation cost can be saved, the installation quality of the air pipes is improved, auxiliary holes are further formed in a civil engineering structure, angle steel inner flanges and maintenance holes are formed in the air pipes, the air pipes in the vertical shaft can be connected through the angle steel inner flanges, and the installation quality of the air pipes in the vertical shaft is improved. The problem that the installation operation space of the long-side shear wall side bolt is insufficient is solved, and the effects that the connection strength between air pipes is enough and the sealing performance is good are achieved.
一种竖井风管安装用的施工方法，所述施工方法包括分段施工、定点拼装、分单元倒装法拼装、剪力墙预留工艺孔、分单元对接口增设单边角钢内法兰与检修孔、设置提升装置和分段风管吊具。每单元的风管三层楼高，吊具的吊点设置在风管上口，在高楼层的竖井顶层上方设置提升装置。本发明的施工方法采用分段式、分单元倒装法进行风管安装，可以节省了大量人工和安装成本，提高风管的安装质量，本发明还在土建结构上设置工艺孔，在风管上设置角钢内法兰及维修孔，可以实现竖井内风管采用角钢内法兰连接，解决了长边剪力墙侧螺栓安装操作空间不足的难题，达到风管间连接强度足够、密封性能良好的效果。
