Plateau high and cold steel truss arch field splicing device and construction method
The invention discloses a plateau high-cold steel truss arch site splicing device and a construction method, and belongs to the technical field of steel truss arch construction equipment. The longitudinal connection angle steel is sequentially connected with the multiple supporting steel pipes, and the horizontal splicing device is used for splicing single sections of the steel truss arch. The vertical splicing device comprises a support steel pipe, a transverse bracing pipe and supporting profile steel; each set of vertical splicing device is provided with four support steel pipes, the four support steel pipes are arranged in a rectangular array mode, every two adjacent support steel pipes in the transverse direction are connected through a transverse supporting pipe, every two adjacent support steel pipes in the longitudinal direction are connected through supporting profile steel, and stiffening ribs are arranged on the supporting profile steel. And the vertical splicing device is used for splicing the single sections into a complete steel truss arch. The horizontal splicing device has the advantages that splicing and trial splicing can be carried out at the same time, the mounting efficiency is high, the splicing device can be reused, the cost is saved, a constructor can complete lofting, lineation, positioning and welding on the ground during horizontal splicing, and high-altitude operation is not needed.
本发明公开了一种高原高寒钢桁拱现场拼装装置及施工方法，属于钢桁拱施工设备技术领域，卧拼装置包括：支撑钢管和纵联角钢；纵联角钢依次与多根支撑钢管连接，卧拼装置用于拼装钢桁拱的单个节段；立拼装置包括支座钢管、横撑管和支承型钢；每组立拼装置均设置有四根支座钢管，四根支座钢管呈矩形阵列设置，横向相邻的两根支座钢管之间通过横撑管连接，纵向相邻的两根支座钢管之间通过支承型钢连接，支承型钢上设置有加劲肋，立拼装置用于将单个节段拼装成完整的钢桁拱。本发明具有拼装和试拼可同时进行，安装效率高，拼装装置可重复利用，节省了成本，卧拼时施工人员在地面上即可完成放样、划线、定位和焊接，无需进行高空作业的优点。
