Embodiment Construction
[0014] A method for installing a liner pipe of a pipe fitting with fixed nodes at both ends, involving such figure 1 The pipe fittings with fixed joints at both ends are shown, joints 1 and 6 at both ends, straight pipe 2 and liner pipe 3,
[0015] Step 1: Weld the integral liner pipe 3 to the node at one end node 1 before installation, and then connect the pipe fitting to the node;
[0016] Step 2: The other end node 6 adopts the following construction method to divide the liner pipe into three equal parts of the curved liner 4 (such as figure 2 ), weld the upper handle 5 on each segment of the arc liner (such as image 3 ), the handle uses welding rod or thick iron wire, etc., and inserts the curved liner into the gap between the node and the straight pipe (such as Figure 4 ), after stuffing it in, rotate it with a welding rod or a thick iron wire to make the arc-shaped lining board stick to the docking port (such as Figure 5 ), after welding the arc-shaped liner with ...

The invention relates to the field of construction of building steel structures. A mounting method of a pipe fitting liner pipe with fixed nodes at the two ends comprises the following steps of: the first step: completing the welding of the integral liner pipe with the node in the position of the node at one end before mounting and further enabling a pipe fitting to be in butt joint with the node; the second step: adopting the following construction method at the node at the other end, trisecting the liner pipe into trisected arc-shaped lining plates, welding a handle on each section of the arc-shaped lining plate, inserting the one arc-shaped lining plate into a gap between the node and a straight pipe, further rotating the handle to enable the arc-shaped lining plate to be close to a butt joint port after the insertion, welding the arc-shaped lining plate with the straight pipe, then planing off the handle, and mounting the other two sections of the arc-shaped lining plates according to the mounting method for forming the integral liner pipe. The mounting method disclosed by the invention is simple in construction method; as the node at one end with a small operation gap adopts the split type liner pipe, namely the arc-shaped lining plates, each arc-shaped lining plate is easy to be inserted into the gap between the straight pipe and the node, and the liner pipe is formed after insertion; and the mounting method can not only facilitate mounting and construction and improve production efficiency, but also meet the requirements on the performances of the pipe fitting and ensure the quality of a product.
Description
technical field [0001] The invention relates to the construction field of building steel structures, in particular to a method for installing liner pipes of pipe fittings with fixed nodes at both ends. Background technique [0002] In the field of construction, during the construction of pipe trusses, the nodes at both ends of the chord are often positioned, and the chord needs to be inserted between the two nodes. Usually, the liner tube at the docking position of the nozzle at one end is fixed on the node first, and the liner tube at the other end is lengthened and put into the chord first. After the chord is positioned, slowly move the liner tube put into the chord to the tube. At the butt joint of the mouth, the positioning of the butt weld liner pipe is realized. After the chord is positioned, the space for the joint is narrow, and it is very difficult to move the liner tube. It is difficult to ensure whether the liner tube is moved to the joint. difficulty.
