JUNCTION STRUCTURE OF A FIXTURE FOR SOLAR CELL PANEL AND A ROOF

摘要

PROBLEM TO BE SOLVED: To provide a junction structure which allows a solar cell panel to be fixed to a roof which is not limited to a plate shape but also includes irregularity and reliably solves a flashing problem.

SOLUTION: A junction structure 1 includes a fixture 20 joined to a plane part 11a on a roof 10 through an adhesive layer 30. The fixture 20 is provided with an upper fixing part 21 for fixing a solar cell panel 40 and a lower joint bottom surface 22 for joining the plane part 11a. The adhesive layer 30 includes a fast-curing A-region 31 formed of an adhesive layer A and a low elastic B-region 32 formed of an adhesive layer B, in the joint surface. The adhesive layer A has a setting time of 180 min or less and a shear strength of 5 N/mm2or higher. The adhesive layer B has an elastic modulus of 0.1 to 100 MPa.
