Description

Technical Field

[0001] This utility model relates to the field of connecting feet technology, and more specifically, to a foundation connecting foot for steel structures in buildings. Background Technology

[0002] Steel structure engineering is a type of structure primarily made of steel, consisting mainly of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. These components are typically connected by welds, bolts, or rivets, and it is one of the major types of building structures. Due to its light weight and ease of construction, it is widely used in large factories, bridges, stadiums, and high-rise buildings. Steel columns cannot be directly fixed to the hard soil layer of the foundation, as the soil will corrode the steel columns; therefore, short concrete columns are poured and fixed to the foundation base.

[0003] When fixing the column base to the concrete, the column base is often bent at the bottom. However, if the top of the column base is vertical and flat, the grip may not be strong enough, which may make the column base not secure. Moreover, after the adjusting bolts are adjusted, they cannot be fixed. This may cause the adjusting bolts to loosen during subsequent pouring and fixing, resulting in low vertical accuracy of the steel column.

[0004] In view of this, this paper studies and improves upon existing problems, and provides a foundation connection footing for steel structures in buildings. The aim of this technology is to solve the problems and improve the practical value. Utility Model Content
