Description

Technical Field

[0001] The utility model belongs to the technical field of steel column bases, and in particular relates to a roof steel column base structure used for building construction. Background Art

[0002] The steel column foot is an important part of the steel structure. Its main function is to transfer the internal force of the lower end of the steel column (including axial force, bending moment and shear force) to the foundation through the secondary pouring of fine stone concrete. The structural requirements of the steel column foot are to reliably transfer the internal force of the column to the foundation, have a firm connection with the foundation, and conform to the calculation diagram as much as possible.

[0003] In the prior art, a Chinese patent with application number 201410081339.9 discloses a new type of steel column foot structure, including a concrete foundation, a column foot steel plate fixedly installed on the concrete foundation, and a steel column vertically connected to the column foot steel plate. A shear key is provided below the column foot steel plate, and a groove matching the shear key is provided on the concrete foundation. The present invention adopts the above structure, and overcomes the shear force generated by driving, wind load, earthquake, snow load and deadweight of the steel frame by using shear keys, thereby avoiding the deviation of the anchor position of the steel column foot in the prior art, and effectively ensuring the safety and reliability of the steel column installation connection. In addition, the column foot structure has a reasonable design, a simple structure, is easy to install, and is convenient to construct, and is easy to promote and use.

[0004] In actual use, the steel columns will generate shear force due to various external forces, which may cause the position of the steel column foot anchor exposed on the top surface of the concrete foundation to deviate, affecting the safety and reliability of the steel column connection. For this reason, we propose a roof steel column foot structure for building construction. Utility Model Content
