Description

  The present invention relates to a support for installing a roof addition facility such as a solar battery panel on a roof and a construction structure of the roof addition facility using the support.

  Conventionally, when a roof additional equipment such as a solar panel is installed on a roof of a building, a support for fixing the roof additional equipment is previously attached on the roof (for example, Patent Documents). 1). The support is composed of a base member fixed to the roof base material and bolts that stand from the base member and project through the roof material. And by fixing the roof additional equipment to this bolt, the roof additional equipment is installed on the roof of the building.

  When attaching a support tool, it is required to secure a strength that can withstand the weight of the roof additional equipment installed on the roof, or to have a waterproof structure that can withstand wind and rain.

  However, in the conventional construction structure as described above, an insertion hole is formed in the roof material in order to project the bolt of the support tool. Moreover, the bolt of the support tool used for construction is formed with a thread groove over the entire bolt. Therefore, in the case of wind and rain, there has been a problem that rainwater that has flowed in from the insertion hole formed in the roof material flows downward through the screw groove of the bolt and enters the roof base of the building.

  Therefore, in Patent Document 1, the roof material insertion hole is sealed with a sealing member. Since a hole through which the bolt of the support tool passes is also formed in this sealing member, a screw groove is formed inside the hole. As a result, a gap is generated, and rainwater easily enters the roof base through this gap.
