  However, in the mounting bracket and the mounting structure of the attached structure to the side roof, the fastening member is provided only at the ridge side end of the mounting bracket. There is a possibility that it cannot be attached to. In addition, since the mounting bracket has a structure in which the fastening force of the fastening member is applied to the horizontal roof via a clamping piece which is a separate part independent of the main body, the number of parts is equivalent to the provision of such a clamping piece. However, there is a drawback that the structure is increased and the structure becomes complicated.

  It is an object of the present invention to provide a support fitting and a rooftop equipment mounting structure that can attach a rooftop equipment such as a solar cell to a horizontal roof with sufficient strength and that has a simple structure.

  In order to solve the above-described problems, the support metal fitting of the present invention has a roof hump at least one of the main body eave side end located at the lower water end of the side roofing material and the main body building side end located at the upper water end. Insertion pieces to be inserted are formed on the lower surface side of the parts, and metal fixture fixing bolts are provided at the main body eaves side end and the main body ridge side end that are provided with metal fixture fixing bolts that press the roof of the respective portions. And a facility fixing portion provided with a mounting bolt for a rooftop facility between the main body eave side end and the main body ridge side end.

Compared to the case where the metal fitting fixing bolt is provided, the on-roof equipment such as a solar cell can be attached to the side roof with sufficient strength. Further, the roof has a structure in which the hull portion is pressed by a metal fixing bolt, and no sandwiching piece which is a separate part independent of the main body is provided, so that the structure can be simplified.

  In the support bracket, the insertion pieces may be formed on the main body eave side end and the main body ridge side end, and may be installed on every other roof.

  Alternatively, one side of the main body eave side end and the main body ridge side end is formed to have a narrower width than the other side so that the end portions of the support brackets can be overlapped and continuously installed on the side roof. It is good as well.

  In these support fittings, it is preferable that a defining surface for defining the arrangement of the side roofing material is formed on at least one of the main body eave side end and the main body building side end. According to this, when installing the supporting bracket while rolling the roofing material, the supporting bracket can regulate the arrangement of the roofing material, so that the roofing material is overlapped with each other at an accurate position. Nose can be formed. And since the pressing force of the said metal fixture fixing bolt can be made to act on the hull part of this roof correctly, the support strength of the support metal fitting by a horizontal roof improves.

  Moreover, the on-roof equipment installation structure of this invention is characterized in that any of the above-mentioned support fittings is arranged on the roof and the on-roof equipment is attached.

  In the on-roof equipment mounting structure, a stepped reinforcing member having an upper plate and a lower plate is provided, the lower plate is fixed to the roof surface, and the upper plate is located at a gap of the roof. It is preferable that the metal fitting fixing bolt is pressed. According to this, even if the roof portion of the roof receives the pressing of the bracket fixing bolt, the deformation degree of the roof portion of the roof due to the pressing can be reduced by the reinforcing metal fitting. In addition, the reinforcing metal fitting, not the hull itself of the roof, firmly receives the pressing force of the metal fixing bolt.

  In the above-described rooftop equipment mounting structure, it is preferable that a stopper portion for receiving the main body eave side end of the support metal fitting is formed in the extending portion of the upper plate of the reinforcing member. According to this, when installing the support fitting while rolling the roofing material, the stopper portion of the reinforcement fitting prevents the support fitting from slipping down. Further, after the construction, even if the bolt loosens in the scale and the support bracket is detached from the roofing material, the stopper portion of the reinforcement bracket prevents the support bracket from sliding off.

  If it is this invention, there exist various effects, such as being able to attach on-roof equipment with sufficient intensity | strength on rooftops, such as a solar cell.
