Embedded column base joint

Abstract

The invention relates to an embedded column base joint. The embedded column base joint comprises a steel pipe column, a bottom plate is arranged at the bottom of the steel pipe column, a plurality ofstuds are arranged on the outer side of the column wall of the steel pipe column, an annular table sleeves the steel pipe column, the annular table comprises a through partition plate and a pluralityof stiffening plates, the through partition plate is perpendicularly connected with the column wall of the steel pipe column, and the stiffening plates are in polygon. The stiffening plates comprise top edges, inner side edges and outer side edges which are sequentially connected, the top edges are connected with the bottom face of the through partition plate, and the inner side edges are connected with the column wall of the steel pipe column. Compared with the prior art, the annular table is arranged to replace a bottom plate to transmit all vertical force to a concrete foundation, the punching face of the steel pipe column to the concrete foundation is transferred to the annular table from the column bottom, the height of a punching cone is greatly increased, under the condition that the burial depth of a concrete foundation bearing platform is limited, the requirement of the steel pipe column for the punching bearing capacity of the bearing platform is met, and the excavation workload is further reduced.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an embedded column base node. Background technique [0002] With the continuous development of society, the construction industry has developed rapidly. In multi-storey steel structure industrial buildings, the column foot form is mostly box-shaped column embedded column foot. The usual method is as follows image 3 As shown, the bottom of the steel pipe column is provided with a bottom plate, and the steel pipe column is selected as a box-shaped column, and the box-shaped column is filled with concrete not lower than the strength level of the concrete foundation. The inner box columns are provided with studs on the columns to resist shear force. The cone surface of the punching cone is as image 3 As shown by the dotted line in the middle, at the bottom plate of the steel pipe column, in order to meet the load-bearing requirements, column foot bolts are also ins...

AI Technical Summary

Problems solved by technology

[0003] With the promotion and application of multi-storey steel structure industrial buildings, and considering factors such as earthquake resistance, the section of the steel pipe column at the bottom is getting larger and larger, so the thickness of the concrete foundation cap is required to be very large, but in many projects, the depth of the foundation cap is limited. , which cannot meet the calculation requirements for embedded column feet

The usual solution is to use outsourcing column feet, but this solution has a certain impact on the usable space on the ground floor of the building
