On-site assembling method for steel structure pipe truss
The invention provides an on-site assembling method for a steel structure pipe truss, which comprises the following steps of: S1, marking a center line intersection point of each node and relative coordinate points at 500mm positions on two sides of the intersection point according to a steel structure pipe truss drawing; s2, an on-site assembling scheme is compiled, an assembling site is lofted, the site is leveled and tamped, and a concrete foundation is poured; s3, a total station is used for setting out the projection of the steel truss to the concrete foundation, and a construction platform frame is assembled according to the setting-out range; s4, lofting to a construction platform frame according to the coordinates of the control points of the jig frame, and welding and assembling the jig frame; s5, an upper chord and a lower chord of the steel structure pipe truss are placed on the jig frame, and a total station is used for lofting node positions and marking the node positions; s6, mounting inclined web members between the upper chord members and the lower chord members according to the node positions, mounting horizontal web members between the upper chord members, and welding; and S7, after re-checking, detection and acceptance check, tire-free hoisting is carried out.
本发明提出了一种用于钢结构管桁架现场拼装方法，包括以下步骤：步骤S1、根据钢结构管桁架图纸，标注出每个节点中心线交汇点和该交汇点两侧500mm位置的相对坐标点；步骤S2、编制现场拼装方案，拼装场地放样并进行场地平整、夯实、浇筑混凝土基础；步骤S3、使用全站仪将钢桁架的投影放样至混凝土基础上，根据放样范围拼装施工平台框架；步骤S4、根据胎架的控制点坐标放样至施工平台框架，并焊接拼装胎架；步骤S5、放置钢结构管桁架的上弦杆和下弦杆至胎架上，使用全站仪放样节点位置并标记；步骤S6、根据节点位置安装上弦杆和下弦杆之间的斜向腹杆，安装上弦杆之间的水平腹杆，并焊接；步骤S7、复核、检测和验收之后，进行脱胎吊装。
