Description

  The present invention relates to a connection structure for a gantry equipped with a drainage part that can be used for laying a solar cell module, a daylighting panel, etc. on a roof of a building having a large flow direction on the roof surface, and a gantry for laying a solar cell module Connection structure.

Conventionally, various types (structures) of installing a solar cell module on the roof of a building part have been proposed. When the type (structure) is roughly divided, it is a structure in which a solar cell module is installed on an existing roof by a support frame or the like, and itself does not require a function (waterproofness) as a roof. Adopted at the time of new installation or replacement, there is a structure in which a solar cell panel is directly installed on a base (field plate, steel frame), and the solar cell panel itself has a function as a roof.
The former has an advantage that it can be applied to various roof surfaces. However, since the former is installed on the roof, a roof is basically required and there is a problem in design. In contrast, the latter is excellent in design because the solar cell panel itself forms the roof surface.

  The structure proposed in Patent Document 1 is an example of the latter, that is, a structure in which a solar cell panel is directly installed on a base, and describes a structure in which a collar portion is formed on a rail-shaped support member.
