Description

Technical Field

[0001] The utility model relates to the technical field of box-type steel column butt joint reinforcement, in particular to a steel plate for dislocation reinforcement of box-type steel column butt joints and a positioning structure thereof. Background Art

[0002] There are three main reinforcement methods for existing box-type hollow steel column connection nodes:

[0003] (1) Use high-strength concrete for filling to increase the bearing capacity and ductility of the node. This method is mainly suitable for the case where the steel column is not high. When the column is too high or too large, pouring concrete will greatly increase the construction difficulty and reinforcement cost;

[0004] (2) Prefabricated steel plates are added around the column joints to form steel plate sleeves, and the stress-bearing performance of the joints is improved by prestressing and other means. However, when there is a misalignment between the upper and lower steel columns, it is difficult for the prefabricated steel plates to fit the column surface to form a strong reinforcement structure.

[0005] (3) Carbon fiber reinforced polymer and other materials are used to reinforce the node area to improve its stress performance. This is often used to reinforce steel-concrete structures. The principle is to use the plasticity and high strength of carbon fiber to make it into the required shape to reinforce the node. However, carbon fiber is expensive and is rarely used in actual projects. Therefore, we need to propose a steel plate and its positioning structure for the misaligned reinforcement of the box-type steel column butt joint. Utility Model Content
