PROBLEM TO BE SOLVED: To reduce installation cost of a solar cell panel, and to ensure the flatness of a panel mounting surface in a trestle for installing the solar cell panel.SOLUTION: A trestle 10 for installing a solar cell panel includes a plurality of purlins 20, a pair of purlin receiving members 16, 18, a pair of support posts 12 supporting the purlin receiving member 16, a pair of support posts 14 supporting the purlin receiving member 18, purlin mounting brackets 22 connecting the purlins 20 to the purlin receiving member 16, and purlin mounting brackets 24 connecting the purlins 20 to the purlin receiving member 18. In a connection part of one support post 12 and the purlin receiving member 16, bolt through holes consist of a round hole and a long hole which is long in the vertical direction, and in a connection part of the other support post 12 and the purlin receiving member 16, bolt through holes consist of a round hole and a long hole which is long in the horizontal direction. The same applies to a connection part of the support post 14 and the purlin receiving member 18. In a connection part of the purlin mounting bracket 22 and the purlin receiving member 16, bolt through holes consist of a long hole and a long hole which is long in a direction orthogonal to the former long hole. |
