Anti-fatigue reinforcing device of steel bracket column

Abstract

The invention relates to an anti-fatigue reinforcing device of a steel bracket column. L-shaped steel plates are bonded between an upper flange plate of a steel bracket and a flange plate of a steel column through steel bonding glue, wherein one L-shaped steel plate is arranged between the upper surface of the upper flange plate and the flange plate of the steel column, two L-shaped steel plates symmetrical and adjacent to a web of the steel bracket are arranged between the lower surface of the upper flange plate and the flange plate of the steel column. Four L-shaped steel plates symmetrically arranged relative to a vertical stiffened rib and the web of the steel bracket correspondingly are bonded between the vertical stiffened rib and the upper flange plate through steel bonding glue. By arranging the L-shaped steel plates in the connecting position of the steel bracket and the steel column, the effect of reducing the horizontal stress in a welding seam can be achieved. The L-shaped steel plates are arranged in the position, corresponding to a crane beam, of the steel bracket, and an asphalt concrete plate containing rubber particles is laid on the upper surface of the steel bracket, so that a buffer function layer can be formed between the steel crane beam and the steel bracket, and the damage resistance property of the steel bracket is improved.

Description

technical field [0001] The invention relates to an anti-fatigue reinforcement device for a steel corbel column, which is suitable for the technical field of steel structure industrial workshops. Background technique [0002] Steel corbels are a very important structural component in industrial plant buildings. They have the advantages of simple construction method, short construction period, reliable theoretical calculation, small cross-section and high bearing capacity. , plays an important role in the long-span spatial structure system. In steel-structured industrial plant buildings, the corbels are connected to the columns, and the crane beams are placed on the corbels. A track is provided on the upper part of the crane beam for the traveling of the crane. [0003] Such as figure 1 and 2 As shown, a structural assembly diagram of a typical steel corbel column in the prior art is shown, including a steel column 10 and a steel corbel 20 . The steel column 10 is a full-...

AI Technical Summary

Problems solved by technology

It can be seen that the fatigue problem is the biggest problem in steel structure industrial workshops. However, the steel structure anti-fatigue reinforcement devices in the prior art, such as welding and bolted connections, have certain limitations. For example, welding will cause weld defects and residual Stress, easy to generate new fatigue crack sources, difficult construction, difficult to guarantee quality, etc. Bolt connection needs to open holes in the original structure to weaken the cross section, prone to stress concentration, restricted by the working space, easy to stress relaxation, etc.
