Twisted cruciform beam-column structure with thrust joint bearing joints

Abstract

The invention provides a torsional cross beam column structure with a thrust knuckle bearing node. The torsional cross beam column structure with the thrust knuckle bearing node comprises steel beams which are connected with a supported structure, a steel column playing a supporting role below the steel beams and a beam column node which is arranged at a connecting position of the steel beams and the steel columns; the steel beams are crossly arranged in an X shape in two directions; a cross position is arranged on the beam column node; the steel column is a hollow steel column with a cross section; the hollow steel column with the cross section and the steel beams which are arranged in an X shape are in a mutually torsional spatial relationship. According to the torsional cross beam column structure with the thrust knuckle bearing node, a thrust knuckle bearing is applied to a building structure, the node size is reduced and the node bearing capacity and the rotation capacity are improved due to a real hinge structure of the thrust knuckle bearing, a building modeling with the hollow steel column with the cross section and the steel beams which are arranged in the X shape being in the mutually torsional spatial relationship is achieved through a simple structural form, and hinging relationship of the beam columns and the bearing capacity of the node are guaranteed.

Description

technical field [0001] The invention relates to a beam-column structure system of a building structure, specifically, a beam-column structure composed of a cross-section column and an X-shaped beam hinged to the direction of the column section. Background technique [0002] With the continuous development of China's construction industry and the continuous improvement of the level of steel structure processing and design, various novel, complex and even peculiar structures continue to appear. Most of these complex structural forms are realized by steel structure systems. The beam-column system is the most common structural form in the structure, and the diversification of structural modeling is also reflected in the diversification of the beam, column components and beam-column joints. Therefore, steel structure beams, columns and beam-column joints with complex forms continue to appear. Various special-shaped steel columns and irregular steel beams are widely used in pract...

Problems solved by technology

However, in the past, the method of setting stiffness hinges was often used in the hinged connection of structural beam-column joints. This structure has problems such as large joint volume, clumsy appearance, low bearing capacity, and small rotation angle.
