Method for rechecking joint precision of large-span pipe truss
The invention provides a method for rechecking the joint precision of a large-span pipe truss. During deepened design, two node units are cut out in the transverse direction to serve as main trusses, the two main trusses are spliced into a whole, a three-dimensional coordinate system is established, and a first support and a second support are constructed; a jig frame, a first support and a second support are manufactured, and upper chord members, lower chord members, diagonal web members, connecting rods and transverse brackets of the two main trusses are installed; adjusting the first support and the second support; the two main trusses are connected; and re-checking the mounting precision of the main truss. According to the method, the precision of the large-span pipe truss node is rechecked in a limited space through a transverse interception method; through the arrangement of the support, the height, the angle and the concentricity of all the components are accurately adjusted, operation is easy, and the working efficiency and the adjusting precision are improved; the device is scientific and reasonable in structure, can be flexibly adjusted according to practical application, is wide in applicability, can be repeatedly used, and saves a large amount of cost.
本发明提供一种用于大跨度管桁架节点精度复核的方法，步骤包括；深化设计时，沿横向截取两个节点单元作为主桁架，将两个主桁架拼接为一个整体，建立三维坐标系并构建第一支座和第二支座；制作胎架、第一支座和第二支座，安装两个主桁架的上、下弦杆、斜腹杆、连接杆和横向牛腿；调节第一支座和第二支座；连接两个主桁架；复核主桁架安装精度。本发明通过横向截取的方法，实现了在有限空间内对大跨度管桁架节点精度进行复核；通过支座的设置，实现了各构件的高度、角度及同心度的精准调节，操作简单，提高了工作效率和调节精度；结构科学合理，可根据实际应用灵活调整，适用性广且可重复使用，节省了大量成本。
