Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing:

[0033] Such as Figure 1-Figure 6 The radial positioning method of the node part of a circular tube member is shown, and the method includes the following steps:

[0034] (1) Determine the datum plane and measure the out-of-roundness of the two ports of the round tube according to the datum plane, and perform circle calibration of the round pipe port. The specific process is:

[0035] a. adopt the steel plate leveled by the spirit level as the datum plane 5, place the V-shaped frame 8 on the datum plane 1 and fix it, and place the round pipe 6 on the V-shaped frame 8; the thickness of the steel plate is at least 20 mm, and the The absolute value of the height error on both sides of the V-shaped frame 8 is less than or equal to 1 mm, the included angle of the V-shaped frame 8 is 90 degrees and the absolute value of the angle error is less than or equal to 0.5 degrees, and ...

Abstract

The invention relates to a radial positioning method for a joint part of a round pipe component. The method includes the following steps: determining a reference surface, acquiring out-of-roundness of two ports of a round pipe according to the reference surface, and performing roundness correction on the ports of the round pipe; measuring two ends of the round pipe after being subjected to port roundness correction according to the reference surface to acquire an upper end point of each port, and performing joint punching on the upper end point to acquire a punching point identity; according to the punching point identity, adopting a laser alignment method for measuring to acquire bending error of the round pipe; according to the bending error of the round pipe, adopting a fire correction method and the laser alignment method to align the round pipe, and determining an axial position of a joint according to size specified by a drawing; adopting the laser alignment method to determine out-of-roundness of the axial position of the joint of the round pipe, and acquiring radial error. By the radial positioning method, the problem of radial positioning of the joint part on a finished pipe with deviation in outer diameter and tortuosity is solved, and connecting accuracy of the component and integral safety of structure are guaranteed.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to a radial positioning method for node parts of circular pipe members. Background technique [0002] Because the cross-section of the circular tube has the characteristics of biaxial symmetry, the moment of inertia is the same for all axes, and the cross-section is closed, the circular tube not only has good bending and compression performance, but also has a large torsional stiffness and good local stability of the member. It is widely used in the field of construction steel structure. At present, straight seam submerged arc welded steel pipes are mostly used in building steel structures at home and abroad. As the main force-bearing structural parts in building steel structures, pipe members need to be connected with other members through nodes to form the skeleton of the building and better exert their good mechanical properties. However, because the LSAW steel pipe is...
