Construction method for improving installation precision of inverted triangular truss
The invention discloses a construction method for improving the installation precision of an inverted triangular truss, which comprises the following steps of: arranging a measuring reflector plate at a bracket pipe orifice on the side surface of a main truss chord member, then measuring relative coordinates of a secondary truss chord member pipe orifice, comparing two groups of relative coordinate data difference values, and adjusting the spatial position of the bracket pipe orifice on the side surface of the main truss chord member, so as to improve the installation precision of the inverted triangular truss. Enabling the new pipe orifice relative coordinate data of the corbel pipe on the side surface of the main truss chord member to be the same as the relative coordinate data of the pipe orifice of the secondary truss chord member; and finally, the secondary truss is connected with the primary truss, secondary truss web member inlaying pipes are installed after butt welding is completed, and secondary truss installation is completed. Through the process, after the secondary truss is lifted, the position of the corbel pipe is not adjusted any more, the pipe orifice of the connecting point of the primary truss and the secondary truss can achieve high-precision butt joint, the secondary truss is installed in place at a time, the construction efficiency and precision are improved, and the construction quality is effectively guaranteed.
本发明公开了一种提高倒三角桁架安装精度的施工方法，在主桁架弦杆侧面牛腿管管口设置测量反射片，然后通过测量次桁架弦杆管口相对坐标，比对两组相对坐标数据差值后，并调整主桁架弦杆侧面牛腿管管口的空间位置，使主桁架弦杆侧面牛腿管新的管口相对坐标数据与次桁架弦杆管口的相对坐标数据相同；最后将次桁架与主桁架进行连接，在对接焊完成后安装次桁架腹杆嵌补管，完成次桁架安装。通过以上流程，次桁架起吊后不再调整牛腿管位置，主次桁架连接点的管口可实现高精度对接，次桁架一次安装到位，提高了施工效率和精度，有效保证了施工质量。
