Penetrating type connecting joint component shaped like Chinese character'mu 'and manufacturing method thereof

Abstract

The invention relates to a through-type connecting joint component shaped like a Chinese character'mu 'and a manufacturing method thereof.The manufacturing method adopts a mode that through-type bracket wing plates lie flat to conduct assembling and welding, firstly, special-shaped bracket upper and lower wing plates are placed on a jig frame to be welded with a first bracket inner side web plate; a first body wing plate with double notches is positioned and welded, and then a first upper partition plate, a first middle partition plate, a first lower partition plate and a second body wing plate are assembled; a second upper, middle and lower partition plate and a third upper, middle and lower partition plate are assembled in sequence; the second bracket inner side web plate is welded with the first bracket inner side web plate and the special-shaped bracket wing plate; the first corbel inner side partition plate, the second corbel inner side partition plate and the corbel wall plate are welded in a three-face mode; and the first bracket outer side web and the second bracket outer side web are installed and welded. And finally, an external H-shaped bracket is assembled, and a floor bearing plate, a lifting lug plate, a connecting lug plate and the like are assembled and welded. The structure is simple, assembling is convenient, and welding is convenient; and the connection strength and rigidity of the house building steel structure truss node are improved.

Description

technical field [0001] The invention relates to a through-type mesh-shaped connecting node component and a manufacturing method thereof, belonging to the technical field of building steel structures. Background technique [0002] The outrigger refers to a solid web beam or truss that is very rigid and connects the inner cylinder and the outer column. Usually, one to several layers of outrigger members are arranged along the height. The mechanism of setting the outrigger truss between the outer frame column and the core tube is to increase the axial force of the outer frame column under horizontal load, thereby increasing the overturning moment borne by the frame and reducing the overturning moment of the inner core tube. Its anti-bending effect on the structure can effectively increase the lateral stiffness of the structure and reduce the lateral movement of the structure. For the frame core tube structure, the lateral displacement can be significantly reduced after setting...

AI Technical Summary

Problems solved by technology

[0003] At present, the outer frame column is a through-type complex box-shaped steel column, the space of the joint cavity is narrow, the internal studs are dense, and there are many partitions. The two adjacent webs are criss-crossed, and the structure is complex; the width of the joint is 4470 mm, the tonnage is 24 tons, the center of gravity of the component is eccentric, it is difficult to turn over, the assembly is inconvenient, and the joint strength and stiffness are not enough
