Method for installing steel pipe truss through opening pipe fitting through sleeve
The invention discloses a method for installing a steel pipe truss through opening pipe fitting through a sleeve. The method comprises the following steps that S1, round pipe sleeves with the same material and the inner diameter equal to that of a to-be-installed through pipe are machined, and the length is not smaller than the sum of the designed lap joint length L1 and the cut-off length L2 of the through pipe through opening; S2, a through opening matched with the outer wall of the penetrated main pipe is formed in one end of the circular pipe sleeve; S3, the whole end of the through pipe is cut along the shortest point of a through opening of the through pipe; and S4, the round pipe sleeve is connected with the penetrated main pipe along the penetrating opening of the round pipe sleeve, the round pipe sleeve and the penetrated main pipe are welded, the position of the penetrating pipe is adjusted, the penetrating pipe and the chord pipe are welded, and finally the round pipe sleeve and the penetrating pipe are welded. According to the method, while the stress requirements of the whole steel pipe truss structure and the mounting joints are met, the problems that through opening pipe fittings cannot be directly mounted in place under the condition that the mounting sequence is limited, pipes are damaged and the like and are inconvenient to mount are solved.
本发明公开了一种套管安装钢管桁架贯口管件的方法，包括以下步骤：S1、加工材质等同、内径等同于待安装贯管的圆管套管，长度不小于设计搭接长度L1和贯管贯口截断长度L2之和；S2、在圆管套管的一端开设与被贯主管外壁相匹配的贯口；S3、对贯管沿其贯口最短点进行整体端部切割；S4、将圆管套管沿其贯口与被贯主管相接，并将二者焊接，调节贯管的位置，将贯管与弦管焊接相连，最后将圆管套管和贯管焊接相连；在满足钢管桁架结构整体和安装节点受力要求的同时，通过本本发明解决了开贯口管件在安装顺序限制的情况下无法直接安装到位和管材破坏等不便于安装的问题。
