Universal joint structure of steel structure x-beam y-column

Abstract

The invention relates to a universal joint structure of an X-beam Y-shaped column of a steel structure. One of the outer wall of the seat body and the inner wall of the sleeve body is provided with layered or spirally distributed limiting grooves, and the other is embedded with a The interior is filled with magnetorheological fluid and the exposed side is a bulge-shaped ring bag that can be elastically embedded in the limit groove. The sleeve body is provided with an electromagnetic coil that surrounds the travel range of the seat body. The electromagnetic coil is connected to the mains or electricity through the control switch. energy storage device. Utilizing the characteristics that the magnetorheological fluid is in a fluid state when it is not energized, it is convenient for the seat body to move up and down for position adjustment; after the seat body moves to the set position, the electromagnetic coil around the magnetorheological fluid is continuously energized, and the electromagnetic coil generates The magnetic field makes the magnetorheological fluid change into a solid state, locks on the limit groove, realizes the in-place locking function of the seat body, reduces the stress on the truss of the seat body, thereby reducing the stress between the beams and columns of the steel structure truss, and improving Wind-resistant reliability and ease of installation.

Description

Technical field [0001] The present invention belongs to the field of steel structural buildings, and more particularly to a universal node structure of a steel structure X beam y-column. Background technique [0002] In modern steel structures, the structure of the column and beam hinges often appear. At present, most of the design of such a hinge node connection is by bolts to achieve approximate articulated nodes, and the bolts are transmitted except for all shear. Pass a small amount of bending in the face of not released. With the development of the social economy, more and more large spans, the structure of tilted column and beam hinges appear, in such a structure, the mode of setting a small amount of bolts to achieve an approximate articulated node is not currently hinged. Requirements, since the node of such structures, the node corner is large, the total bending moment is large, and the hinge node is used with a bolt, which is not released, which is large enough to make ...

Problems solved by technology

[0004] However, when the seat body is lifted by the traction force of the rotating core body and is in the middle position, because the seat body is suspended in the air, and in order to ensure that the seat body is sufficiently wear-resistant, its own weight is relatively large, so after it is adjusted in place, the seat body will exert a pull-down effect on the rotating core body The pull-down force will generate bending and torsional stress on the steel structure truss, which will have an adverse effect on the installation and wind resistance of the steel structure truss
