Aerial butt-joint hoisting method for large-span pipe truss
The invention discloses an aerial butt-joint hoisting method for a large-span pipe truss. The aerial butt-joint hoisting method for the large-span pipe truss comprises the following steps that S1, construction preparation is carried out, specifically, before construction, mechanical devices and materials approach, welding personnel are certified to be on duty, and related personnel are organized by technicians to carry out training and disclosure, so that operators can fully master specific construction practices and key points, and full-time safety inspection personnel are dispatched to carryout supervision and inspection; the operation environment of the construction site is laid out, it is ensured that obstacles in the hoisting site are removed, and an operation platform is set up andmeets the corresponding safety and operation requirements; and S11, a movable triangular jig frame is manufactured by using section steel, and a chord frame is fixed on a hardened horizontal plane according to the elevation of a design drawing. According to the aerial butt-joint hoisting method for the large-span pipe truss, the use cost of a crane is saved, the assembling progress of the pipe truss is accelerated, the assembling time is reduced, construction is carried out by adopting the method, the applicability is high, the process is simple, and the hoisting assembly is high in precision,safe and reliable, economical and practical.
本发明公开了一种大跨度管桁架空中对接吊装方法，包括如下步骤：S1施工准备：施工前机械装置、材料进场，焊接人员持证到岗,由技术员组织有关人员进行培训和交底，使操作人员充分掌握施工的具体做法和要点，并设置专职安全检查人员进行监督检查；布置施工现场的作业环境，保证吊装场地障碍物已移除，操作平台搭设完成并符合相应安全及操作要求；S11用型钢加工制作一个可活动的三角形胎架，在弦杆架按设计图纸标高在硬化的水平面上固定。本发明节省了吊车的使用成本，加快了管桁架拼装进度，减少了拼装时间，采用本工法进行施工，适用性强，工艺简单，吊装组对精度高，安全可靠，经济实用。
