Bending and torsional pipe member splicing method

Abstract

The invention particularly relates to a bending and torsional pipe member splicing method. The method comprises the steps of building a bending and torsional pipe member model; enabling a lowest pointof the model to be located on a horizontal reference surface; selecting three central axis points on a central axis of the model and defining a first plane; leading out a perpendicular line perpendicular to the central axis from the central axis points, setting a stand column model by taking an intersection point of the perpendicular line and a sideline of the bending and torsional pipe member model as a tangent point, and enabling the stand column model to be tangent to the bending and torsional pipe member model; building a corbel model, translating the corbel model and enabling the corbelmodel to be tangent to the sideline of the bottom of the bending and torsional pipe member model and a sideline of the stand column model; measuring data of a distance from a central line of the corbel model to the upper skin of the end part of the bending and torsional pipe member model in three-dimensional simulative software, and performing recording; and during splicing, taking the distance data obtained in the step 6 as a standard and checking the data by adopting a flexible rule. The bending and torsional pipe members complex in shape are subjected to simulative splicing by adopting a simulative check method, and the data is measured, so that the engineering quality is improved.

Description

technical field [0001] The invention relates to the field of steel structure construction, in particular to a method for assembling bent and twisted pipe components. Background technique [0002] With the emergence of a large number of special-shaped steel structures in space, a large number of bending and torsion components appear in the project. Its in-depth design, processing and on-site installation are all difficult, and the accuracy is difficult to control. Especially when installing on site, the ground is first assembled in blocks. The existing technology often uses a roughly positioned assembled tire frame, and then uses three-dimensional coordinates to measure and locate the joints and the position in the pipe for assembly. When encountering irregular intersections or For parts with inconspicuous features such as elliptical bevels, assembly errors are likely to occur due to processing errors and inaccurate point selection on site.
