Description

Technical Field

[0001] This utility model mainly relates to the field of steel structure technology, and specifically to a steel structure column base. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of beams, columns, trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to their light weight and ease of construction, steel structures are widely used in large factories, stadiums, and high-rise buildings.

[0003] Some steel structure column bases are often fixed with bolts, but under repeated loads or dynamic loads, the bolts may loosen, leading to a decrease in the stability of the entire structure and thus affecting the safety of the structure. Utility Model Content
