  However, in the mounting apparatus shown in Patent Document 1, the head on which the bolt is rotated is located at a position lower than the height position of the upper surface of the solar panel at the position where the bolt is arranged. Therefore, the operation of rotating the bolt head with a manual or electric tool such as a wrench must be performed with care so that the tool does not come into contact with the side of the solar panel. The work for rotating the bolt head cannot be performed quickly, and it is difficult to improve workability. Such a problem occurs remarkably when bolts are arranged between the solar panels placed on the rail member with a space therebetween.

  An object of the present invention is to provide a mounting device for an installation on a roof that can easily perform an operation of rotating a head portion of a bolt and can improve workability.

  A mounting apparatus for an installation on a roof according to the present invention includes a pressing member for pressing the installation on the roof placed on a rail member installed on the roof from above, and a downward extension from the head to the pressing member. The protruding male screw shaft is inserted from the top to the bottom, and the head that is operated to rotate applies a downward pressing load to the pushing member, whereby the installation object on the roof and the pushing member are And a bolt for clamping and fixing with a rail member, wherein the head of the bolt is at a height of an upper surface of the roof installation at the position where the bolt is disposed. The height position is the same as or higher than the position.

  In the roof installation object mounting apparatus according to the present invention, the head of the bolt is at the same height as or higher than the height position of the upper surface of the roof installation object at the position where the bolt is disposed. Therefore, when the work of rotating the bolt head with a manual or electric tool such as a wrench is performed, this tool does not contact the side surface of the installation on the roof. Work for rotating the head can be performed quickly, and workability can be improved.

  And such an effect is arrange | positioned between the installation objects on the roof by which the attachment apparatus which concerns on this invention was mounted on the rail member at intervals, and the head of the bolt of this attachment apparatus is wrench etc. When the operation of rotating with a manual type or electric type tool is performed, it is obtained as a remarkable one.

  In addition, in the case where the mounting device for an installation on the roof according to the present invention is provided with a rail engaging member that is inserted into the inside of the rail member and engaged with the rail member. The rail engaging member is formed with a female screw hole into which the male screw shaft of the bolt is screwed, and the head portion of the bolt is rotated so that the male screw shaft is screwed into the female screw hole. The installation object on the roof may be clamped and fixed.

  In addition, the roof installation object mounting device according to the present invention includes a rail engaging member that is inserted into the rail member and engaged with the rail member. When the female screw hole into which the male screw shaft of the bolt is screwed is formed in the rail engaging member, the mounting device temporarily stops the pushing member from descending with respect to the rail engaging member. The head is rotated and the male screw shaft is screwed into the female screw hole to provide a temporary stop means that can lower the pushing member with respect to the rail engaging member. The temporary stop height position from the rail member for the pressing portion that presses the upper surface of the installation object on the roof of the pushing member when temporarily stopped is higher than the upper surface of the installation object on the roof placed on the rail member. It may be used as the location.

  According to this, before the head of the bolt is rotated and the male screw shaft is screwed into the female screw hole, the temporary stopping means temporarily stops the pushing member from descending with respect to the rail engaging member. The temporary stop height position from the rail member with respect to the pressing portion that presses the upper surface of the installation object on the roof of the pushing member when temporarily stopped by the temporary stopping means is on the rail member. Since it is higher than the upper surface of the installation object on the roof, the installation object on the roof placed on the rail member below the pressing part of the pushing member when temporarily stopped by the temporary stopping means. Can be arranged. Then, the pushing member can be lowered with respect to the rail engaging member by rotating the head of the bolt and screwing the male screw shaft of the bolt into the female screw hole of the rail engaging member. Therefore, it is possible to easily perform the work of clamping and fixing the installation object on the roof by the pushing member and the rail member.
