The present invention is not limited to the first and second embodiments.
First, various cases can be considered for the number of structural members to be coupled to the structural material coupling joint from the horizontal direction. In addition, the number of structural material engaging members attached to the structural material coupling joint body may be various depending on the number.
Further, in the first embodiment, the gantry 1 has two stages, and in the second embodiment, the gantry has a three-stage structure. However, there are cases where the gantry has four or more stages. Conceivable.
In addition, there are various cases in the shape of the structural material.
In addition, the illustrated configuration is merely an example.

  The present invention relates to, for example, a structural material coupling joint and a structural material coupling structure for linking a plurality of structural materials, and particularly relates to a device that has been devised so that it can be easily assembled and can have high rigidity. It is suitable for the structure for connecting structural members constituting the pedestal.
