Abstract

The invention relates to the technical field of structural engineering and discloses a concrete filled steel tubular column-beam joint structure and a construction method thereof. The concrete filledsteel tubular column-beam joint structure is composed of an upper concrete filled steel tube, a lower concrete filled steel tube and an H-type steel beam; the lower end of the upper concrete filled steel tube is provided with a steel cylinder, and the outer wall of the steel cylinder is attached to the inner wall of the upper concrete filled steel tube to form a convex structure; the upper end ofthe lower concrete filled steel tube is provided with a groove matched with the steel cylinder; the circumference of the jointed part between the upper concrete filled steel tube and the lower concrete filled steel tube is provided with a steel plate, which is provided with connecting units for connecting the H-type steel beam. The concrete filled steel tubular column-beam joint structure is simple in form, high in connecting and fixing strength, rapid in construction and capable of enhancing the integral connecting strength of concrete filled steel tubular column-beams.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a steel pipe concrete column-beam joint structure and a construction method thereof. Background technique [0002] Concrete has high compressive strength but weak bending resistance, while steel, especially section steel, has strong bending resistance and good elastic-plastic properties, but it is prone to instability and loses axial compressive capacity when it is under compression. Concrete-filled steel pipe can combine the advantages of the two in structure, which can make the concrete in a state of lateral compression, and its compressive strength can be doubled. At the same time, due to the existence of concrete, the rigidity of the steel pipe is improved, and the two together Playing a role, it has the advantages of high bearing capacity, good plasticity and toughness, convenient construction, good fire resistance, and good economic benefits, and has been wid...
