Transfer node for upper-layer steel pipe column and lower-layer reinforced concrete column and construction method

Abstract

The invention discloses a transfer node for an upper-layer steel pipe column and a lower-layer reinforced concrete column and a construction method. The transfer node is a connection point of the upper-layer steel pipe column and the lower-layer reinforced concrete column; the upper-layer steel pipe column is inserted into a transfer node area, and the transfer node area is connected with a reinforced concrete beam in the horizontal direction; within the transfer node area, an annular plate is welded to the inner side of the upper-layer steel pipe column and is provided with a grouting hole; steel pipe studs are welded to at least one side of the inner side and the outer side of the upper-layer steel pipe column; and a T-shaped bracket is welded to the outer side of the upper-layer steel pipe column and comprises a bracket flange, a bracket web and bracket studs, wherein the bracket flange extends in the horizontal direction, the bracket web is arranged at the bottom of the bracket flange and extends downwards, and the bracket studs are arranged on the bracket web. The transfer node for the upper-layer steel pipe column and the lower-layer reinforced concrete column has the advantages of being good in stress performance, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of construction engineering and combined structures, in particular to a conversion node and a construction method of an upper-layer steel pipe column and a lower-layer reinforced concrete column. Background technique [0002] In related technologies, in recent years, many building structures adopt a structural form in which the bottom is a reinforced concrete column and the upper part is a steel pipe column. What kind of transition joint structure should be adopted at the junction of the upper steel pipe column, the lower reinforced concrete column, and the reinforced concrete frame beam has always been the focus of attention. In existing projects, steel pipes are often inserted into concrete columns, and the depth of insertion is the height of a floor. Although this method can ensure the safety of the structure, it is too conservative, the waste of steel is serious, and the construction is cumbersome and d...
