Example Embodiment

[0015] Reference figure 1 , The combined structure of the steel tube bundle of the upsetting web is composed of a steel tube bundle assembly. The steel tube bundle assembly is composed of a plurality of steel tube units connected in sequence. The steel tube unit has a cavity, and the cavity is poured with concrete 4;

[0016] The steel pipe unit is composed of an upset web 3 separated between a parallel continuous flange 1 and a splicing flange 2. The end of the upset web 3 without an upset is vertically welded to the continuous flange 1. Above, the upsetting head 31 of the upsetting web 3 is welded to the welding seam of the adjacent splicing flange 2;

[0017] The steel pipe unit at the front end and the steel pipe unit at the rear end are respectively sealed and welded by steel plates 5; the upsetting web 3 forms a partition between adjacent steel pipe units.

[0018] Further, the inner side walls of the continuous flange 1 and the splicing flange 2 are respectively provided wit...

Abstract

The invention discloses a steel tube bundle composite structure of upset head webs. The steel tube bundle composite structure comprises a steel tube bundle assembly. The steel tube bundle assembly comprises a plurality of steel tube units which are sequentially connected with one another, each steel tube unit is provided with a cavity, and concrete is poured in each cavity; a continuous flange and spliced flanges which are parallel to one another are separated from one another by the upset head webs to form the steel tube units, the end, which is not provided with an upset head, of each upset head web is perpendicularly welded on the continuous flange, and the upset heads of the upset head webs are welded on weld joints among the adjacent spliced flanges; the front-end steel tube unit and the rear-end steel tube unit are respectively closed and welded by steel plates; partition plates among the adjacent steel tube units are formed by the upset head webs. The steel tube bundle composite structure has the advantages that the performance of steel can be sufficiently played by the upset head webs as compared with an existing web with a bent end, and accordingly steel can be saved; the upset heads are closely laid on flange plates, so that the steel tube bundle composite structure is favorable for guaranteeing full and flat weld joints, and the quality of the weld joints can be improved.

Description

technical field [0001] The invention relates to a composite structure of a steel tube bundle with a web of a heading head, and belongs to the field of building structures. Background technique [0002] In the combined structure of steel pipe bundles, the connection between the steel pipe bundles is realized by flange butt welding. In the web plate that bends one end of the steel pipe bundle into an L shape, the bent short side is used as the flange butt welding of the steel pipe bundle. When installing the lining strip, to ensure that the flange plate and the lining strip are closely connected, it is necessary to ensure that the short side of the web bending has sufficient length, so that the steel plate at the bending arc of the web cannot be used, and the web Large deformation may occur at the bend of the plate, which will affect the flatness of the wall. The web of the heading head in the steel pipe bundle can not only play the role of a liner when the flange is welded, ...
