Description

  The present invention relates to a solar cell module fixing structure, and more particularly to an improvement in a structure capable of firmly fixing a solar cell module to an installation surface such as a roof.

  When fixing a solar cell module using the roof of a building as an installation surface, it is common to use a rack extending in a rail shape. The solar cell module is supported by a frame having a rectangular frame shape, and the solar cell module can be fixed by fixing the frame to a frame.

By the way, in a solar cell module that is required to be thin, as a result of requiring reinforcement in the module surface, a reinforcing member is disposed between opposing side members of a frame that is disposed so as to surround the outer peripheral side. A configuration is known in which the strength in the module surface is maintained by a reinforcing member (see, for example, Patent Document 1).
According to this, even if the solar cell module is thinned, it can be expected to maintain a certain strength.

Japanese Patent No. 3673234

  However, in the configuration described in Patent Document 1, when the solar cell module is configured to be fixed to the gantry, the fixing between the gantry and the reinforcing member is not considered at all. Has a structure in which the frame located on the outer peripheral side is simply fixed to the gantry. Therefore, the solar cell cannot fix a plurality of locations in the plane of the module to the installation surface side, resulting in inconvenience that reliability is low in fixing strength.

[Object of invention]
The object of the present invention has been devised by paying attention to such inconveniences, and the object of the present invention is to improve the fixing strength by fixing the surface of the solar cell module to the installation surface side. It is in providing the fixing structure of a solar cell module.

In order to achieve the above object, the present invention adopts the structure described in the claims. Specifically, the solar cell module whose outer peripheral side is surrounded by a frame, at least two mounts that are laid on a predetermined installation surface and extend in parallel with each other, and are disposed between these mounts and the solar cell module Including a fixed unit,
The fixing unit includes a first fixing unit that is detachably and positionally adjustable on the mount, and a second fixing unit that is fixed to the back surface of the solar cell module and extends between opposing side members of the frame. Including
The solar cell module is fixed to the installation surface side by positioning the second fixed unit so as to straddle between the mounts and connecting the second fixed unit to the first fixed unit. .

Further, the present invention provides a solar cell module whose outer peripheral side is surrounded by a frame, at least two mounts that are laid on a predetermined installation surface and extend in parallel to each other, and are disposed between these mounts and the solar cell module. And a fixed unit
The fixing unit includes a first fixing unit provided so as to be movable along the gantry and a second fixing unit that is fixed to the back surface of the solar cell module and extends between opposing side members of the frame. ,
The first fixed unit and the second fixed unit are engaged with each other by positioning the second fixed unit so as to straddle between the mounts and sliding the first fixed unit along the mounts. A configuration in which the solar cell module is fixed to the installation surface side can also be adopted.

According to the present invention, the second fixed unit disposed on the back side of the solar cell module is provided to be connected to or engaged with the first fixed unit mounted on the gantry in a state of straddling the gantry. Therefore, it is possible to fix a plurality of locations in the plane of the solar cell module to the gantry.
Therefore, the solar cell module is fixed between the outer peripheral side and the in-plane, and can be firmly fixed to the installation surface. In addition, the second fixing unit reinforces the surface of the solar cell module, and can sufficiently cope with the thinning required recently.
Moreover, when the structure which slides a 1st fixing unit along a mount frame is employ | adopted, work can be facilitated by performing the said slide operation on the outer side of a flame | frame.

The fixed unit 13 is integrated. The spacer 35 is fixed so as to be positioned at two places in the longitudinal direction of the second fixing unit 13. The fixing position is a position where the bolt 32 protruding from the slit 25 of the mount 11 is just engaged with the notch 42 of the spacer 35 when the solar cell module 10 is set at a predetermined position of the mount 11. The

  In the above, the solar cell module 10 is leveled and placed on the gantry 11, and the solar cell module is slid along the gantry 11 so that the bolts 32 enter the notches 42 of the first fixed unit 12, and the two are engaged. . Then, a jig is straddled between the outer surface side of the frame 15 and the gantry 11 and an outer peripheral fixing jig (not shown) is straddled to fix the frame 15 to the gantry 11. Fixing can be completed.

  Therefore, according to such 1st Embodiment, the part which fixes to the installation surface side can be formed also in the surface of the solar cell module 10, Thereby, it becomes possible to fix the solar cell module 10 firmly. In particular, it is possible to provide a fixing structure corresponding to the thinning of the module.
