Abstract

The securing structure for a solar cell module includes a placement member installed on roof and having a groove in an upper surface, an external thread portion extending upward from the placement member, at least one flat plate-like shim member having a slit through which the external thread portion passes and a through-hole, and stacked on the placement member, a flat plate-like connecting member placed on the shim member, having an insertion hole through which the external thread portion passes, a droop portion drooping in the groove of the placement member through the through-hole, and a plurality of upward projecting portions projecting upward and sticking in the solar cell module, and having conductive property, and a first securing member and a second securing member pressing downward the solar cell module placed on the connecting member with screwing between the external thread portion and an internal thread portion.

Claims

1. A securing structure for a solar cell module comprising:

a placement member installed on roof and having a groove extending in one direction in an upper surface;

an external thread portion extending upward through the groove of the placement member;

at least one flat plate-like shim member having a slit opened to one side in the direction that the groove through which the external thread portion passes extends and a through-hole penetrating through the shim member at a side opposite to the slit, and stacked on the upper surface of the placement member;

a flat plate-like connecting member placed on an upper surface of the shim member, having an insertion hole through which the external thread portion passes, a droop portion drooping in the groove of the placement member through the through-hole of the shim member at an outer side relative to the insertion hole, and a plurality of upward projecting portions projecting upward from positions separated in the direction that the groove extends with respect to the insertion hole and sticking in a lower surface of the solar cell module placed so as to be separated from the external thread portion in the direction that the groove extends, and having electrical conductive property; and

a securing member abutting against an upper surface of the solar cell module placed on the connecting member, and pressing downward the solar cell module with screwing between the external thread portion and an internal thread portion.

2. The securing structure for the solar cell module according to claim 1,

wherein the upward projecting portions are arranged just above at least the upper surface of the placement member.

3. The securing structure for the solar cell module according to claim 1,

wherein the connecting member further includes a downward projecting portion projecting downward and sticking in the shim member, and

the shim member has a length longer than a length of the connecting member in the direction that the groove extends and further includes a screw hole penetrating through the shim member at an outer side relative to the connecting member.

4. The securing structure for the solar cell module according to claim 2,

wherein the connecting member further includes a downward projecting portion projecting downward and sticking in the shim member, and

the shim member has a length longer than a length of the connecting member in the direction that the groove extends and further includes a screw hole penetrating through the shim member at an outer side relative to the connecting member.
