Japanese Patent No. 5612732

However, the support metal fitting having the above-described configuration has a problem that it is not necessarily applicable to a vertical flat roof or a folded plate roof that does not have a fitted goby portion because the fitting gouge portion in the folded plate roof is an attachment target. .
Further, in the above-mentioned support metal fitting, when the gore part is firmly sandwiched between the tips of the left and right side nail plate parts, stress that breaks the left and right side upright plate parts is concentrated around the middle part in the height direction. Therefore, it has been necessary to reinforce so as to have a thickness sufficient to withstand the stress.
As a result, the overall thickness of the support bracket will increase and the weight will also increase, which may hinder workability on site, increase the material cost of the support bracket, and affect construction costs. have.
Therefore, in the present invention, the metal roof has versatility that can be clamped even in any configuration of the roof portion of the metal roof, and has a high connection fixing strength to the metal roof, and also acts when the shell portion is clamped. An object of the present invention is to provide a support member for a solar cell panel in which breakage stress is dispersed so that it can be formed as thin as possible.

In view of the above problems, the solar cell panel support metal fitting according to the present invention is attached to a goby portion that rises in parallel to the direction of the metal roof, and corresponds to the front and rear of the flow direction of the metal roof. A pedestal for placing the solar cell panel is provided, a plate-like right leg is continuously formed below the right edge of the pedestal, and a right claw piece whose tip is directed to the left is formed at the lower edge of the right leg. A right grip part formed by projecting and continuously forming a projecting piece inclined downward to the left on the lower left edge of the pedestal, and inserted between the projecting piece of the right grip part and the right claw piece, and A terrace that can be mounted and matched with the pedestal and the projecting piece is provided, and the terrace is provided with an upper step that can be attached to and detached from the pedestal and a lower step that rotatably receives the tip of the projecting piece. A plate-like left leg is continuously formed on the lower edge, and the tip of the left leg is directed to the right at the lower edge of the left leg. The left gripping part is formed by projecting a left claw piece facing to the left gripping part, and a screw part projecting upward from the upper step part of the left gripping part has a long, elongated slot on the right and left. The base part of the goby part is sandwiched between the left and right claw pieces by being inserted into the nut and tightened with the nut.
In addition, the left and right leg portions that continue downward from the lower right edge of the pedestal portion and the lower edge of the lower step portion, respectively, are formed in a circular arc plate shape that protrudes outward.

In short, since the present invention has the above-described configuration, the nut is loosened and disposed above the screw portion, the right claw piece of the right grip portion and the left claw piece of the left grip portion are vertically separated, and the screw portion is gripped by the right grip. By tilting to the right end side of the slot, the gap between the left and right claw pieces can be expanded vertically according to the shape and size of the various gouges on the metal roof. Even if it is a goby part, it is inserted in the hollow part comprised between the right side grip part and the left side grip part, and the base part of a goby part can be arrange | positioned between right-and-left claw pieces.
Next, by tightening the nut, the pedestal and protrusion of the right grip and the terrace (upper and lower) of the left grip approach each other, so that the distance between the left and right claw pieces of the left and right grips is increased. When the base of the narrowed goby part is clamped in the same way as in the past, and the pedestal part and the protruding piece correspond to the terrace part, and the tip of the protruding piece is received by the lower stage part of the terrace part, this part is used as a fulcrum. The left and right gripping portions can generate rotational power in the opposite direction, and can further increase the clamping force of the left and right claw pieces against the base of the goby portion.
Therefore, according to the present invention, it is possible to provide a highly reliable support metal fitting with high connection fixing strength to a metal roof.

In addition, in the state where the left and right claw pieces of the left and right side gripping parts firmly hold the base of the goby part as described above, the right side gripping part and the left and right side gripping part both have left and right leg parts in a circular arc plate shape. In the case where it is formed, the stress acting on each leg portion is uniformly distributed by tightening the nut, and the stress concentration as in the conventional case can be prevented.
Therefore, according to the present invention, the thickness of the support metal fitting can be formed as thin as possible, the weight of the support metal fitting can be reduced, the material cost of the support metal fitting can be reduced, and the construction cost can be reduced. The effect is great.
