  By the way, since the beam span is usually as large as about 6 to 8 m, generally steel materials are used in consideration of the rigidity of the gantry. However, if a long structure is formed of steel material, the size and weight of the gantry increase. Therefore, when installing the gantry on the roof of the building, it is necessary to use a crane or the like. In order to reduce the weight of the pedestal, it is conceivable to reduce the thickness of the steel material. However, in this case, the strength of the pedestal with the box placed on the pedestal will be reduced, such as during an earthquake. There was a risk that the frame would be deformed by vibration and the support of the box would become unstable.

  The present invention has been made in view of the above circumstances, and it is intended to provide a gantry capable of reducing the weight of the gantry, increasing the structural strength, and facilitating transportation and installation work to an installation location. Objective.
