[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 There may be large deformation at the bend of the plate, which will affect the flatness of the wall

The invention discloses a headed-web steel tube bundle combined structure comprising a steel tube bundle assembly. The steel tube bundle assembly is formed by connecting a plurality of steel tube units. Each steel tube unit is provided with a cavity in which concrete is poured. Each steel tube unit is composed of a plurality of T-shaped units. Each T-shaped unit comprises a first flange and a headed web vertically arranged on one side of the first flange; the parts, arranged on two sides of the headed web, of the first flange are a second flange and a third flange. The adjacent T-shaped units are reversely arranged in such manner that the headed webs face each other; the head of the headed web in each T-shaped unit is welded to a weld joint between the first flanges of two T-shaped units arranged on the other side in the same direction as the former T-shaped unit; the second flange of one front T-shaped unit, the third flange of one rear T-shaped unit and the headed webs of the front and rear T-shaped units jointly enclose to form one steel tube unit. The headed webs allow the performance of steel material to be given to fuller play as compared to bent-end webs, and the steel material is saved.
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, ...
