Description

Technical Field

[0001] This utility model relates to the field of column base reinforcement technology, and in particular to a seismic-resistant embedding device for column bases of steel structure garages. Background Technology

[0002] Steel structure buildings have been increasingly widely used in building structures in recent years due to their quick construction and lightweight design, especially in factory buildings. As the final load-bearing component of the steel structure system, the safety of the steel column base is of paramount importance.

[0003] Currently, column base reinforcement mainly employs the following technical methods: First, the traditional bolt reinforcement method, which uses high-strength bolts to tightly connect the reinforcement component to the original structure; second, steel plate welding reinforcement technology, which uses welding processes to firmly combine the reinforcement steel plate with the original column base; and third, prestressed reinforcement method, which improves the structural stress performance by applying prestress.

[0004] Bolt reinforcement requires drilling holes in the original column base. If the drilling position is off or the hole diameter is too large, it will directly weaken the cross-sectional area of ​​the column base. During welding reinforcement, the high-temperature electric arc will change the metallographic structure of the original column base steel, causing the local material to become brittle and reducing the toughness of the original structure. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a seismic-resistant embedding device for steel structure garage column bases, which aims to improve the problem of unstable column base fixing.
