Method for installing main truss of steel truss bridge
The invention relates to the technical field of steel truss girder installation construction, in particular to a main truss installation method of a steel truss girder bridge, which comprises the following installation steps: step S1, installing a vertical web member, step S2, installing an upper chord member, step S3, remeasuring and adjusting the elevation of the upper chord member, step S4, installing a lower chord member, step S4, installing an inclined web member, and step S6, remeasuring and adjusting the elevation of the lower chord member. And S7, the steps S1-S6 are repeated, and installation of the primary truss is completed. The first supporting device and the second supporting device are arranged at the joints of the two ends of the vertical web member, so that the upper chord member can be conveniently adjusted again through the first supporting device and/or the second supporting device after being installed; the third supporting device is arranged between the diagonal web member and the lower chord member, the first lifting device is arranged between the diagonal web member and the upper chord member, and the first lifting device is arranged between the upper chord member and the lower chord member, so that the lower chord member can be conveniently adjusted by adjusting the third supporting device, the first lifting device and the second lifting device after being installed.
本发明涉及一种钢桁梁安装施工技术领域，特别涉及一种钢桁梁桥的主桁架安装方法，包括以下安装步骤：步骤S1：安装竖腹杆，步骤S2：安装上弦杆，步骤S3：所述上弦杆标高复测、调整，步骤S4：安装下弦杆，步骤S4：安装斜腹杆，步骤S6：所述下弦杆标高复测、调整，步骤S7：重复步骤S1‑S6，完成主桁架的安装。通过在竖腹杆两端连接处设置第一支撑装置和第二支撑装置，便于上弦杆安装后通过第一支撑装置和/或第二支撑装置进行再次调整，通过在斜腹杆与下弦杆之间设置第三支撑装置、在斜腹杆与上弦杆之间设置第一提拉装置和在上弦杆与下弦杆之间设置第一提拉装置，便于下弦杆安装后通过调整第三支撑装置、第一提拉装置和第二提拉装置进行调整。
