For this positioning, conventionally, the fitting and the beams 43, 44 are fitted to each other. Positioning holes are provided in the fitting part, and when the beams 43, 44 are fitted into the fitting, the positioning pins are inserted into these positioning holes, which brings the beams 43, 44 into the positioning state. We were doing welding work between the hardware and the beams 43 and 44.

[Problems to be Solved by the Invention]

Conventionally, as described above, it is possible to position the beam by providing the positioning holes in the fitting portions where the fitting and the beam are fitted to each other and inserting the positioning pins into these positioning holes. This is because the fitting portion of the beam and the beam had a length long enough to provide the positioning hole. However, in order to increase the strength of the beam joints of the pillars, for example, when a box-shaped beam joint fitting is provided at this beam joint, depending on the shape and structure of the joint fittings In some cases, it is not possible to secure a sufficient length of the fitting portions to be fitted to each other. In such a case, a positioning means different from the conventional one is required for positioning the beam.

An object of the present invention is to provide a housing in which the beam can be positioned during the welding operation of the joining metal member and the beam even if the length of the fitting portion where the joining metal member provided on the pillar and the beam are fitted to each other is short. The present invention is to provide a positioner for connecting beam-columns of a unit.
