Structure node for steel girder and reinforced column and construction method thereof

Abstract

The invention relates to a structure node for a steel girder and a reinforced column, belonging to the technical field of constructional engineering and combined structures. The node consists of a rectangular steel tube, a protruding steel girder and a transmission part, wherein the rectangular steel tube consists of steel plates, the inner wall of each steel plate is welded with studs, the protruding steel girder comprises an upper flange plate, a lower flange plate, a web and studs welded on the upper flange plate, the protruding steel girder is welded on the outer wall of the rectangular steel tube, and the transmission part is welded on the inner wall or outer wall of the rectangular steel tube. In the construction process, the invention is placed in a node area, and then the steel girder of a floor system is connected with the protruding steel girder of the structure node after concrete is poured and reaches certain strength. The structure node can generate restraint effect towards the concrete in a core area and obviously improve load-carrying capability of the concrete. The invention can be used as a concreting template and the moulded structure is nice looking. The structure node for the steel girder and the reinforced column in the invention has the advantages of good load-carrying capability, simple structure, convenient construction, and sound technical and economicbenefits.

Description

Technical field [0001] The invention relates to a structural node of a steel beam and a reinforced concrete column, belonging to the technical field of construction engineering and composite structures. Background technique [0002] With the continuous development of the structural form of high-rise buildings, many new structural systems have emerged. For example, in multi-high-rise buildings or multi-storey industrial plants, the mixed use of reinforced concrete columns and composite floors is on the rise. This requires To solve the connection problem between the steel beam and the reinforced concrete column in the composite floor, the traditional connection method is to add a section of steel (section steel) to the node area of ​​the reinforced concrete column, which is to design according to the connection method of the steel reinforced concrete column and the steel beam. However, the connection structure of this kind of node is complicated, and it is difficult to bind steel b...

[0002] With the continuous development of the structural form of high-rise buildings, many new structural systems have emerged. For example, in multi-high-rise buildings or multi-storey industrial plants, the mixed use of reinforced concrete columns and composite floors is showing an increasing trend, which requires To solve the connection problem between the steel beam and the reinforced concrete column in the composite floor, the traditional connection method is to add a section of steel frame (section steel) to the joint area of ​​the reinforced concrete column, that is, to design according to the connection method between the steel reinforced concrete column and the steel beam, However, this kind of joint connection structure is complicated, and it is very difficult to bind steel bars and pour concrete in the joint area, and it is difficult to ensure the compactness of the concrete in the joint area.
