A through hole is formed at a position facing a plurality of bolt holes provided in both steel frame beams when the two web frames of the two steel frame beams to be joined are brought into contact with each other, coaxially with the bolt holes. With respect to the main body that is the joint plate that has been opened, a rotating pin that pivotally supports the main body on the web portion of one of the steel beams and the rotary pin that pivots along the web surface of the steel beam, and project from the main body surface coaxially with the through hole. The cylindrical cap to be installed, the bolt whose head is directed toward the cap side and which is housed in each cap coaxially with the through hole, and which is respectively interposed between the bolt head and the ceiling surface inside the cap, With the spring biasing the bolt in the direction of the through hole and the through hole of the main body and the bolt hole of the steel beam facing each other, turn the main body downward from the bottom side of the main body or above the main side of the main body. Extended towards And a handle part that is provided with the handle.

The joining device is preliminarily arranged in a state where a handle portion of the joining device projects laterally from an end face of one steel beam to be joined, and the other steel beam to be joined is joined to both steel beams. While holding the end faces facing each other so that they can face each other, by lowering them from above or raising them from below, the flange of the other steel beam pushes the handle part of the above-mentioned joining device up or down and pivots the joining device. A method for joining steel beams, wherein the bolt holes of both steel beams and the through holes of the joining device are coaxially opposed to each other.
