Temporary adjustable butt joint support for large-span special-shaped steel pipe truss supported by springs and construction method of temporary adjustable butt joint support
The invention provides a large-span special-shaped steel pipe truss temporary adjustable butt joint support supported by springs and a construction method of the large-span special-shaped steel pipe truss temporary adjustable butt joint support, and belongs to the field of pipe truss temporary supports. The problem that a plurality of temporary supports need to be machined according to circular pipes with different diameters in the installation and splicing process of the pipe truss is solved. A corrugated steel plate is installed on a steel frame of the support, the section of the corrugated steel plate is in a trapezoid shape, lug plates and sliding blocks are installed on the two sides of the corrugated steel plate, the sliding blocks can slide in the transverse direction of the corrugated steel plate, bolts penetrate through the lug plates to abut against the side walls of the sliding blocks, a plurality of springs are installed in a groove in the middle of the corrugated steel plate, and bottom pipe clamps or side face pipe clamps are installed on the springs. The two sides of the side face pipe clamps are fixed to the sliding blocks through connecting rods. The pipe clamp with the spring is arranged to adapt to pipe truss chord members with different diameters, circular pipes with various diameters can be effectively supported, the pipe clamp can be repeatedly used during pipe truss hoisting construction, the construction workload is effectively reduced, and waste of steel is avoided.
本发明提出了一种采用弹簧支撑的大跨度异形钢管桁架临时可调节对接支座及其施工方法，属于管桁架临时支座领域。解决了管桁架安装拼接过程中需要根据不同直径圆管加工多个临时支座的问题。该支座的钢框架上安装有波形钢板，波形钢板的截面呈梯形，波形钢板的两侧安装有耳板和滑块，滑块能够沿波形钢板的横向滑动，螺栓穿过耳板抵紧滑块侧壁，波形钢板的中部凹槽上安装有若干弹簧，弹簧上安装有底部管夹或者侧面管夹，侧面管夹的两侧通过连接杆与滑块固定。本发明设有带弹簧管夹以适应不同直径的管桁架弦杆，对多种直径的圆管均能提供有效支撑，可在管桁架吊装施工时重复使用，有效减少施工工作量，避免钢材的浪费。
