A manufacturing method of space torsion box-shaped joints

Abstract

The invention discloses a method for manufacturing a space-twisted box-shaped joint, which includes a method for deepening and drawing a bent plate of the box-shaped joint, bending the plate, and an overall assembly of a box body. If a single plate is bent in multiple places, the bending line, bending tilt height, and bending angle in the conventional deepening drawing are easy to overlap, resulting in unclear bending dimensions in the workshop; overturning the drawing of the original deepening bending drawing In this way, the unbending position is taken as the reference horizontal plane, and the bending line, bending angle, and bending tilting height are reflected in the top view of the unfolded view or bending view (marked with positive and negative values ​​relative to the reference plane). For this special-shaped component, a dot-deep drawing is made, and a tire frame is erected for assembly according to the coordinate size of each point. The manufacturing method of this node is derived from the single-layer box-shaped wave roof project, which is especially suitable for the manufacture of steel structure buildings with torsion sections at the end of the box.

Description

A method of making a space twisted box-type node technical field [0001] The invention belongs to the field of steel structure buildings, and in particular relates to a method for making a space twisted box joint. Background technique In recent years, domestic large-scale airports, railway stations and Olympic sports venues and other related steel structure buildings, the vast majority of roofs are made of steel. Single-layer roofs or trusses made of round tubes or H-beams. With the diversification of structures, multi-owners and designs begin to lean towards water chestnuts The United States, the use of boxes or other special-shaped structures to replace the round tube, multiple connection positions cannot be connected in the same way as the round tube. In order to meet the stress requirements of the structure and the beauty of the water chestnut, special-shaped box openings are used for butt joints, and the joints are mostly made of bent plates. When a single plate...
