FIG.

Next, the solar cell module mounting bracket according to the embodiment of the present invention will be described with reference to the drawings.
FIG. 1 schematically shows a state in which a solar cell module 1 is laid using a plug-in bracket 3 and a fixed bracket 4 according to the present embodiment on a laying surface such as a roof.
Note that the plug-in bracket 3 and the fixed bracket 4 are respectively related to different embodiments, but both are one embodiment of the present invention, and are used at the same time to place the solar cell module 1 on the mount 2. Fix it.

The laying surface in this example is a sloped roof.
On this laying surface, a plurality of mounts 2 for installing the solar cell module 1 are attached in parallel to each other from the water side to the water side.

On the other hand, each solar cell module 1 is sequentially connected on the two bases 2 along the length direction of the base 2 with the direction from the water side to the water side as the continuous direction x.
In addition, the group of solar cell modules 1 laid in a row in the continuous direction x can be laid in a plurality of rows in a direction orthogonal to the continuous direction x, whereby the solar cell modules 1 are laid vertically and horizontally. The In this case, the solar cell module 1 is laid in contact with the vertical and horizontal directions. In this example, the direction in which the solar cell modules 1 are connected via the solar cell module mounting brackets 3 and 4 is referred to as a continuous direction x.
Further, in the following, for convenience of explanation, a group of solar cell modules 1 laid in a row in the continuous direction x, the first solar cell module 1, the second solar cell module 1,. It may be referred to as the nth solar cell module (n is a natural number of 2 or more).

As shown in FIG. 1, in each solar cell module 1, two plug-in brackets 3 are attached on the water side, and two fixed brackets 4 are attached on the water side.
Further, in the second to n-th solar cell modules 1, the plug-in bracket 3 is located at a position where the solar cell module 1 hits the outside of the gantry 2 when the solar cell module 1 is installed on the gantry 2, and the fixed bracket 4 is the same. Is attached to a position overlapping with the gantry 2.
On the other hand, in the first solar cell module 1, the fixed bracket 4 is attached at a position overlapping the gantry 2 as in the second to nth solar cell modules 1, but the plug-in bracket 3 is also mounted on the gantry 2. It is attached to the position that overlaps.
In addition, in this embodiment, although the structure which attaches the plug-in type bracket 3 in the position which hits the outer side of the mount frame 2 was shown, you may attach this invention to the position which hits the inner side of the mount stand 2 not only in this.

Further, the water-side end portions of all the solar cell modules 1 are fixed on the gantry 2 by a fixed bracket 4.
On the other hand, the lower end of each solar cell module 1 is not directly fixed on the gantry 2, but a flange 34 of the plug-in bracket 3 described later is adjacent to the lower side. It contacts the lower surface of the solar cell module 1 from below (facility surface side). Thereby, the solar cell module 1 is restricted from moving upward (on the light receiving surface side).

About each such solar cell module 1, when the lower end which is not directly fixed to the gantry 2 is referred to as a free end, and the upper end which is directly fixed to the gantry 2 is referred to as a fixed end, it is laid. The group of solar cell modules 1 are laid so that free ends and fixed ends are alternately arranged along the continuous direction x.

Next, the configuration of the solar cell module 1 will be described.
As shown in FIG. 2A, the solar cell module 1 includes a hollow frame-shaped frame 12 and a solar cell submodule 11 attached in the frame 12.
The solar cell submodule 11 is a substrate that includes a solar cell element that generates power by receiving light at least, and is laminated with a cover glass or the like that protects it appropriately.
The solar cell element applied to the present embodiment is a silicon crystalline (single crystal silicon, polycrystalline silicon), amorphous (amorphous silicon), compound (CIS, CdTe, GaAs, etc.), or organic solar cell. Any element or the like may be used, and the type is not particularly limited.

The frame 12 is a frame that holds the solar cell submodule 11 and protects the laminated end face, and is made of a metal such as aluminum. The frame 12 is configured in a rectangular shape corresponding to the outer peripheral shape of the solar cell submodule 11 by connecting the ends of the four rod-shaped frame constituent members at right angles.

Further, as shown in FIGS. 2B and 2C, the frame 12 holds the solar cell submodule 11 from the upper surface side and the solar cell submodule 11 from the lower surface side. A lower surface side sandwiching portion 122, a plate-like support portion 123 extending from the end of the upper surface side sandwiching portion 121 and the lower surface side sandwiching portion 122 at a right angle to the lower side (the gantry 2 side), and a support portion It is formed from a plate-like base portion 124 that extends from the lower end portion of 123 at a right angle.

Further, among the side edges of the frame 12, the base portion 124 is placed on the gantry 2 at the water-side end and the water-side end facing each other in the continuous direction x (the length direction of the gantry 2). Further, the support portion 123 supports the solar cell submodule 11 on the gantry 2.

The vertical width of the gap formed in a frame shape by the upper surface side sandwiching portion 121 and the lower surface side sandwiching portion 122 is slightly larger than the thickness of the solar cell submodule 11, and forms a groove 12a that opens to the hollow portion side. ing. The outer periphery of the solar cell submodule 11 is inserted into the groove 12a with a filler such as butyl rubber interposed. Thereby, the solar cell submodule 11 and the frame 12 constitute the solar cell module 1 integrally.

The gantry 2 is a bar-like member that is installed in parallel on a laying surface such as a roof and supports the solar cell module 1 on the laying surface in pairs, and is made of a galvanized steel plate or the like.
As shown in FIG. 3A, the gantry 2 is formed in a vertically long rectangular column shape with both ends opened, and a bottom surface portion 21 placed on the laying surface and a pair perpendicular to the bottom surface portion 21. And a pair of mounting portions 23 on which the solar cell module 1 is mounted in parallel with the bottom surface portion 21.

An opening 24 is formed between the pair of placement portions 23 along the length direction of the gantry 2.
In addition, bolt holes 22a are formed in the pair of side surface portions 22 in the vicinity of the water-side end portions. This bolt hole 22a is a hole formed corresponding to the bolt hole 252a of the cover 25 in order to attach a cover 25 (see FIG. 3B) described later.

As shown in FIG. 3B, a cover 25 is attached to the underwater side end of the gantry 2 when the solar cell module 1 is installed.
The cover 25 includes a plate-shaped front surface portion 251 that covers the open end of the gantry 2 on the underwater side, a plate-shaped side surface portion 252 that covers the side surface portion 22 of the gantry 2, the mounting portion 23, and the opening The plate-shaped upper surface portion 253 that covers the portion 24 and the plate-shaped hooking portion 254 that is erected at a right angle upward from the water-side end portion of the upper surface portion 253.

Bolt holes 252a are formed in the pair of side surface portions 252 corresponding to the bolt holes 22a (see FIG. 3A) formed in the side surface portion 22 of the gantry 2, respectively.
The underwater side end of the gantry 2 is covered with the cover 25, and the cover 25 is attached to the gantry 2 by inserting bolts 252 b into the bolt holes 252 a of the cover 25 and the bolt holes 22 a of the gantry 2.
The bolt 252b is screwed into a female screw or a nut formed in advance on the inner peripheral surfaces of the bolt hole 252a and the bolt hole 22a, whereby the cover 25 is fixed to the gantry 2.

Next, the plug-in bracket 3 and the fixed bracket 4 according to the embodiment of the present invention will be described with reference to the drawings.
First, the plug-in bracket 3 will be described with reference to FIGS.
The plug-in bracket 3 is a metal fitting for installing the solar cell module 1 on the gantry 2, and is attached to the base portion 124 on the underwater side of the solar cell module 1.

Next, the fixed bracket 4 will be described with reference to FIGS.
The fixed bracket 4 is a metal fitting for installing the solar cell module 1 on the mount 2, and is attached to the base portion 124 on the water side of the solar cell module 1.

The fixed bracket 4 is also made by extrusion molding of aluminum or an alloy mainly made of aluminum, for example, as with the plug-in bracket 3. Similarly, the width is sufficiently smaller than the width in the longitudinal direction of the base portion 124 of the solar cell module 1 and is at least equal to or smaller than the opening width of the opening 24 of the gantry 2 (the width between the mounting portions 23).

The latch piece 43 is formed to rise upward at a right angle from the end of the lower surface side clamping portion 413. Further, the latching piece 43 is formed in parallel with the support portion 123 of the solar cell module 1 as shown in FIG. 8 or FIG. 9 showing a state where the fixed bracket 4 is attached to the solar cell module 1. Then, it comes into contact with the support part 123 from the outside without any gap. Thereby, the latching piece 43 latches on the support part 123 of the solar cell module 1, and the detachment of the fixed bracket 4 in the underwater direction is prevented.

Note that at least the height of the retaining piece 43 is preferably equal to or less than the height of the support portion 123 of the solar cell module 1, and in this case, when the fixed bracket 4 is attached to the base portion 124, The latch piece 43 does not jump out to a position higher than the upper surface of the solar cell module 1.
Moreover, since the thickness of this latching piece 43 forms the clearance gap between the adjacent solar cell modules 1, it can do it, after ensuring the thickness which can ensure sufficient intensity | strength to latch on the solar cell module 1. It should be as thin as possible.

The flange 44 is a portion fixed to the gantry 2 when the solar cell module 1 is laid.

In the fixed bracket 4 having the above-described configuration, the gap of the sandwiching portion 41 that sandwiches the base portion 124 of the solar cell module 1 is formed slightly larger than the thickness of the base portion 124 of the solar cell module. Accordingly, the upper and lower surfaces of the base portion 124 abut against the upper and lower surfaces of the sandwiching portion 41 without any gap, and the fixed bracket 4 is attached to the solar cell module 1 without moving in the vertical direction.

Further, the length from the groove depth of the hooking groove 42 to the hooking piece 43 is formed to be slightly larger than the width of the base portion 124 of the solar cell module 1. As a result, the base portion 124 of the solar cell module 1 that is hooked in the hooking groove 42 is in contact with the hooking piece 43 and the groove depth of the hooking groove 42, so that the fixed bracket 4 is The solar cell module 1 is attached to the solar cell module 1 without moving in the water-side direction or the water-side direction.

Here, the fixing bracket 26 is a bracket for fixing the fixed bracket 4 on the mount 2 and is formed by bending a single metal plate into a substantially U-shaped cross section.
As shown in FIG. 10 (a), the fixing bracket 26 rises at right angles from a bottom surface portion 261 in which bolt holes 261 a corresponding to the bolt holes 44 a of the fixed bracket 4 are formed, and both side edges of the bottom surface portion 261. And a pair of side surface portions 262.

As shown in FIG. 10B, the width of the bottom surface portion 261 is larger than the width of the opening 24 of the gantry 2 (the width between the placement portions 23), and the hollow portion or the bottom surface portion 21 of the gantry 2. It is configured to be smaller than the width. The height of the side surface portion 262 is such that when the solar cell module 1 to which the fixed bracket 4 is attached is placed on the mount 2, the opening of the mount 2 of the fixed bracket 4 into the hollow portion. It is configured to be equal to the depth of the intrusion part.

When the solar cell module 1 placed on the gantry 2 is fixed to the gantry 2 by the fixing metal fitting 26, as shown in FIG. 11, the opening is disposed in the hollow portion of the gantry 2 with the opening portion facing upward. The bolt 261b is inserted into the bolt hole 261a of the fixed bracket 26 and the bolt hole 44a of the fixed bracket 4, and screwed into a nut or a female screw formed in advance on the inner peripheral surface of the bolt hole 261a and the bolt hole 44a. Let
As a result, the upper end of the side surface portion 262 of the fixture 26 comes into pressure contact with the lower surface of the mounting portion 23 of the gantry 2. As a result, in the solar cell module 1, the movement in the upward direction and the water-side direction or the water-side direction (continuous direction x) is restricted by the frictional force between the side surface part 262 and the mounting part 23, and the gantry 2 Fixed on top.
In the present embodiment, the fixing metal fitting 26 and the gantry 2 are separate members, but the fixing metal fitting 26 and the gantry 2 may be a single member formed integrally. Furthermore, when the fixing bracket 26 and the gantry 2 are integrally formed, the shape of the fixing bracket 26 is not limited to a substantially U-shaped cross section, and a flat plate-shaped fixing bracket is fixed to the side surface portion 22 of the gantry 2.

Thus, the plug-in bracket 3 and the fixed bracket 4 attached to the base portion 124 of the solar cell module 1 can be slid along the base portion 124 hooked in the hooking grooves 32 and 42. it can. Thereby, when installing the solar cell module 1 on the mount 2, the plug-in bracket 3 and the fixed bracket 4 can be moved to a predetermined position according to the arrangement of the mount 2, and the construction is convenient. .
More specifically, when the gantry 2 is installed on a roof of a house, the gantry 2 is attached to a member having a strong structure such as a rafter. Here, since the positions of the rafters and the like constituting the roof are different for each roof, as a result, the installation interval of the gantry 2 is also different for each roof. Here, since the plug-in bracket 3 and the fixed bracket 4 of the present invention are slidable along the base portion 124 of the solar cell module 1, even if the installation interval of the gantry 2 varies, the solar cell module 1 can be attached to the gantry 2.

Then, the process of attaching the solar cell module 1 to which the insertion type bracket 3 and the fixed type bracket 4 are attached to the mount 2 in order will be described.
First, the first solar cell module 1 is attached to the mount 2.
In this step, first, the plug-in bracket 3 and the fixed bracket 4 attached to the first solar cell module 1 are slid along the base portion 124 of the solar cell module 1 so as to overlap with the gantry 2. I will bring.
