Problems solved by technology

However, in actual use, since the steel column is subjected to various external forces, such as: driving, wind load, earthquake, snow load, and the self-weight of the steel frame, shear force will be generated, resulting in the steel column foot anchor bolt exposed on the top surface of the concrete foundation. The position often deviates, making it difficult or impossible to install the base plate at the bottom of the steel column, thus affecting the safety and reliability of the steel column connection

Abstract

The invention provides a solid joint column base structure which comprises a steel column web, steel column outer edge plates, four reinforcing plates and a bottom plate. One steel column outer edge plate is connected to each of the lateral sides at two ends of the steel column web. The reinforcing plates includes two first reinforcing plates and two second reinforcing plates. The two first reinforcing plates are disposed on the surface of the steel column web. The two second reinforcing plates are respectively connected with the steel column outer edge plates at two ends. The steel column web, the steel column outer edge plates and the reinforcing plates are respectively connected with the upper end of the bottom plate. Anti-shearing steel is disposed at the lower end of the bottom plate. The solid joint column base structure has the advantages that two pairs of reinforcing plates are provided, the whole column base structure is high in strength, and good fixing effect on building structures is achieved.

Description

technical field [0001] The invention relates to a building reinforcement structure, in particular to a fixed column base structure. Background technique [0002] Today, the steel column foot is the connecting member between the steel column and the concrete foundation, usually composed of the column foot plate, anchor bolts, stiffeners, etc., and its function is to transmit the support reaction force and restrain the displacement of the column bottom. However, in actual use, since the steel column is subjected to various external forces, such as: driving, wind load, earthquake, snow load, and the self-weight of the steel frame, shear force will be generated, resulting in the steel column foot anchor bolt exposed on the top surface of the concrete foundation. The position often deviates, making it difficult or impossible to install the base plate at the bottom of the steel column, thus affecting the safety and reliability of the steel column connection.
