Description

  The present invention relates to an on-roof fixture that is mounted on a roof by being sandwiched between bolt bodies protruding from the top of a corrugated roof.

  In general, various devices and parts such as TV antennas, air conditioners, solar panels, heat shield sheets, etc. are placed on the top of corrugated roofs such as folded plate roofs (square corrugated roofs) and round corrugated roofs. Conventionally, various on-roof fixtures for attaching various devices and members on the roof have been proposed (see, for example, Patent Documents 1 and 2).

  The roof described in Patent Document 1 is a peak portion of a corrugated roof in which mountain portions and trough portions are alternately continuous, and a superposed portion formed by overlapping adjacent roof materials is screwed with a bolt body and a nut. It is structured to be connected and fixed by wearing. And the on-roof fixture to be attached to the corrugated roof has a tip opposite to the male thread portion of the bolt body for connecting the roof material that protrudes from the lower portion of the corrugated roof through the overlapping portion. It can be installed by pinching with a pinching piece.

  Specifically, this on-roof fixture is constructed by tightening both leg pieces with tightening bolts and nuts that penetrate the both leg pieces of the sandwiching tool formed in a substantially portal shape in the lateral direction, and from the lower ends of both leg pieces. Both clamping pieces extending so as to face each other are clamped to the bolt body. Therefore, since the tip of the sandwiching piece is locked and fixed in a state where the tip of the sandwiching piece has bitten into the screw groove of the bolt body, the on-roof fixture is firmly fixed on the roof without being easily detached.

  Moreover, the thing of patent document 2 is comprised from a pair of clamping member by which the clamping tool was fulcrum-connected, and has a structure clamped with respect to the goby part in a top part, but this kind of thing is piled up. Even when it is applied to a type roof and formed into a structure that is clamped to a bolt body with both clamping pieces, it can be assumed that the on-roof fixture is similarly firmly fixed on the roof.
