Embodiments of the present invention will now be described with reference to the drawings. Embodiment 1 FIG. 1 to 5 show a fixing device for a panel structure according to the first embodiment. As shown in FIG. 1, this fixing device is applied when a panel structure 1 such as a solar module used for photovoltaic power generation is installed on a roof or the like, and includes a gantry 2, a holding cover 3, and bolts 4.
And the fixing bracket 5. The panel structure 1 such as a solar module is provided with a hook-like mounting flange 7 having a front-facing engagement groove 6 which protrudes outward on the peripheral front surface.

The gantry 2 is made of a hollow square pipe-shaped extruded aluminum material as shown in FIG.
Is configured as The receiving surface 8 is divided by a bolt insertion groove 9 formed at the center in the longitudinal direction, and an upright 10 for positioning is integrally formed at an edge of the groove 9 side. The gantry 2 itself is arranged and fixed such that the receiving surface 8 faces the front side at the installation location such as on the roof as shown in FIG. 1, and the lower end edge of the back surface of the panel structure 1 can be held by the opposing receiving surfaces 8. Is done.

The panel structure 1 is mounted on the gantry 2
The lower end edge of the back surface is placed on the receiving surface 8 and is arranged. Therefore, the outer peripheral side portions of the panel structures 1 laid on the gantry 2 are exposed (portion A in FIG. 1), but the inner peripheral side portions are abutted by the adjacent panel structures 1. A portion and a portion (portion B in FIG. 1) that face each other with the groove 9 of the gantry 2 interposed therebetween at substantially the interval of the groove 9 are formed.

In this state, each panel structure 1 is mounted on the gantry 2 by using the bolts 4 and the fixing brackets 5 at several positions of the holding cover 3.
