Technical Field

The utility model relates to a steel column butt joint technical field, in particular to different forms cross-section steel column butt joint connection structure.

Background

The butt joint mode of the steel structure steel columns comprises a butt welding mode. Butt joint refers to the joint and fixation of the butt joint parts at the ends of each part, and carpenters often refer to a joint method in which wood grains are perpendicular or non-overlapping on opposite sides and reinforced by hoops, also called "end joint"; and (4) fillet welding. The angle joint refers to a joint in which the two end parts form an included angle of more than or equal to 30 degrees and less than or equal to 135 degrees, and is called an angle joint. The joint is not well stressed and is often used in unimportant structures. According to different thicknesses of welding pieces, the grooves can be divided into I-shaped, J-shaped with truncated edges, double-single-side V-shaped with truncated edges, K-shaped and the like and lap welding forms. The lap joint refers to the connection formed by mutually overlapping two reinforcing steel bars according to certain requirements when the lengths of the reinforcing steel bars are not enough.

The existing steel column butt joint connecting structure with different forms of sections has the following disadvantages: when the steel column main bodies are fixedly butted, the upper and lower steel column main bodies need to be butted, so that the upper and lower steel column main bodies are positioned on the same vertical line and are fixed through bolts, and the fixation is complex and cannot be limited at the beginning.
