Description

Technical Field

[0001] The utility model belongs to the technical field of column foot structures, and more specifically, particularly relates to a novel column foot structure with lateral force resistance. Background Art

[0002] The column base of a steel structure is an important part in a building. In a steel frame structure, the columns are located at the four corners and the center of the building, and bear the load. The bottom of the column is connected to the foundation or structural foundation, while the top transfers the horizontal load. Therefore, the bottom of the column requires a stable component with sufficient strength to ensure the stability and safety of the entire structure of the building. The existing application number is CN201922109389.4, which is an anchor bolt and column base structure. A steel plate is welded at the bottom of the steel column and the steel plate is fixed to the foundation by bolts. Since the steel plate is perpendicular to the bolt, when the column receives lateral force, the bolt is easily subjected to shear force, thereby reducing the strength of the bolt. Therefore, a new column base structure with lateral force resistance is proposed. Utility Model Content
