A kind of bolted joint with side plate for eccentric beam-column and assembly method

Abstract

The invention discloses a bolted joint with a side plate used for an eccentric beam column and an assembly method for the bolted joint. The bolted joint with the side plate comprises a first steel plate and a second steel plate which are arranged at the two sides of a multi-cavity steel tube concrete combined column, wherein the first steel plate comprises a first section of the steel plate, a second section of the steel plate and a third section of the steel platewhich are mutually connected; the first section of the steel plate and the third section of the steel plate are symmetrically arranged at the two sides of the second section of the steel plate; the first section of the steel plate and the third section of the steel plate are arranged at the two ends of the second section of the steel plate in an inclined manner; a third steel plate is further arranged on the other side wall of the multi-cavity steel tube concrete combined column; the two ends of the first section of the steel plate and the two ends of the third section of the steel plate are in contact with the third steel plate; and the third section of the steel plate and the third steel plate are parallel to the second steel plate. The joint disclosed by the invention is high in assembly degree, and is reliable in connection; the multi-cavity steel tube concrete combined column, the steel plates, a steel beam, ear plates, the third steel plate and connecting angle steel can be all prefabricated in a factory, so that welding workload during mounting is reduced, and positioning andthe assemblingy are is only needed to be positioned during field installation.

Description

technical field [0001] The invention relates to a structural system of a multi-cavity steel pipe concrete composite column in the technical field of construction engineering, in particular to a bolt node with a side plate for an eccentric beam column and an assembly method. Background technique [0002] The multi-cavity steel pipe concrete composite column composite structure system is a new type of steel pipe concrete composite column structure system that solves the problem of protruding column feet in residential systems. It has the advantages of high bearing capacity, good plasticity and toughness, and convenient construction. [0003] At present, my country's "Technical Regulations for Rectangular Concrete-filled Steel Tube Structures" (GECS159: 2004) provides steel-beam joints for concrete-filled steel tube composite columns, which mainly include inner diaphragm type and outer ring plate type. But so far, there are the following deficiencies in the connection between ...

AI Technical Summary

Problems solved by technology

Because when the side length is small, it is not only difficult to weld, but also hinders the concrete pouring in the pipe. In addition, the beam flange and the inner partition plate penetrate the weld on both sides of the same column wall, and the steel produces a large welding residual stress, which makes the steel at the joint easy to produce delamination or brittle failure

[0005] (2) Affect the appearance and use of buildings

And when applied to corner columns, the horizontal ring plate not only hinders the installation of wall panels, but also causes the reinforcement ring to protrude from the building facade, causing convex corners at the indoor and outdoor joints, which affects the look and feel, which needs to be solved by decoration or ceiling

[0006] (3) The mechanical properties of joints and the simplicity and economy of construction cannot be both

In practical applications, some types of joints have better mechanical properties, and the overall stiffness of the joints is also good, but the amount of materials is large and the construction is complicated
