Axial connecting device for steel members

The utility model relates to the technical field of axial connection of steel members, in particular to an axial connection device for steel members, which overcomes the defect that the strength of the members is easy to weaken in the existing steel member trepanning connection construction, and comprises a steel member and a hoop sleeved outside the steel member, the hoop is arranged outside the two steel members in a sleeving mode, the adjusting rod is rotated to adjust the distance between the extrusion plates on the two sides of the hoop according to the thickness of the steel members, at the moment, the sleeve is kept horizontal only through pressing of the pressing rod, the friction plates at the ends of the extrusion plates are tightly attached to the steel members, and under the action of friction force, the hoop and the two steel members are tightly fixed; the quick connection function is achieved, and practicability is high. 本实用新型涉及钢构件轴向连接技术领域，尤其涉及一种钢构件轴向连接装置，解决了现有钢构件开孔连接施工易削弱构件强度的缺点，包括钢构件以及套设在钢构件外部
