Description

Solar cell panel support bracket and solar cell panel mounting structure using the same

This invention relates to a solar cell panel support fitting for fixing a solar cell pal in an inclined state with respect to the horizontal direction. More specifically, the present invention relates to a solar cell panel support bracket for installing a solar cell panel on a rooftop, a flat roof, a ground, or the like.

As a support fitting for fixing a solar cell panel to a flat roof, one disclosed in Patent Document 1 below is known.

The support metal fitting of Patent Document 1 includes a pair of left and right holding plates that are clamped and fixed to an upper portion of a concrete curb as a base placed on a flat roof, a support plate that obliquely connects these upper ends, It has a presser foot fixed on top. Bolts for tightening are inserted and held above the pair of sandwiching plates. The presser fitting has a bottom plate portion fixed to the upper surface of the support plate, an upright portion extending upward at a right angle from the bottom plate portion, and a panel presser portion bent at a right angle from the upper end of the upright portion. It is generally Z-shaped.

Such a support fitting is provided above the solar cell panel in the tilt direction, and below the tilt direction is provided with another support fixture that holds the lower end of the solar cell panel in the tilt direction.

¡Since the support bracket is fixed to the concrete curb and the solar panel is held, the flat roof is not damaged and no unexpected rain leak occurs.

However, there is a drawback in that a manufacturing cost is required because a bolt is required to displace the pair of sandwiching plates in the proximity direction and sandwich the concrete curb. Further, since the bolts must be tightened one by one when fixing the support bracket, the operation is not easy.

Instead of fixing to the base by tightening as in the support fitting of Patent Document 1, a method is also proposed in which the bolt is used vertically and the lower end of the bolt is fixed to the base. That is, the gantry structure of patent document 2 is a structure which hold | maintains the lower end part of a volt | bolt beforehand to the heat insulation block as a base formed in the raising bottom shape, and fixes the gantry | carrying body which hold | maintains a solar cell panel to this bolt upper part. .

However, when the bolt is fixed to the heat insulating block in advance, the heat insulating block becomes bulky, and handling and workability are poor. For this reason, it is conceivable to make a vertical hole for inserting a bolt in a base block at the site and fix the bolt. However, such a drilling operation is very laborious and the workability is not good.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing a solar cell panel 11 and a gantry 21 on which the solar cell panel 11 is installed. The solar battery panel 11 is installed on a suitable horizontal or substantially horizontal installation surface 18 such as a rooftop, a flat roof, or the ground by a gantry 21.

The solar battery panel 11 has a known structure, and a rectangular plate-like solar battery module 12 having a tempered glass (not shown), a solar battery cell (not shown), a back sheet (not shown), and the like is formed in a square shape from the surface. It is configured to be held by a frame-shaped aluminum frame 13. The back surface of the aluminum frame 13 is formed in an L-shaped cross section, and has a leg piece 14 that floats the solar cell module 12 and an overhanging piece 15 that projects from the lower end of the leg piece 14 to the inner peripheral side (see FIG. 5). . The leg pieces 14 are formed with the same width over the entire circumference of the aluminum frame 13. Similarly, the overhanging piece 15 is also formed with the same width over the entire circumference of the aluminum frame 13.

The gantry 21 includes a hollow concrete block 31 (hereinafter referred to as a “block”) for construction as a building block, and a plurality of pedestals 21 that are fixed to the block 31 and support the solar cell panel 11 while being inclined with respect to the horizontal direction. A plurality of solar cell panel support brackets 41 (hereinafter referred to as “support brackets”) are provided.

The block 31 has a rectangular block shape in which the upper surface 32 and the lower surface 33 (bottom surface) form a predetermined large rectangle, and a plurality of penetrating holes are provided in the middle portion of the predetermined thickness in the thickness direction along the short direction of the upper surface 32 and the lower surface 33. It has a shape having the hollow 34. That is, the cavity 34 is opened on the flat side surface of the upper surface 32 and the lower surface 33 on the longitudinal one side.

There are a plurality of types of the block 31 in terms of dimensions, such as the thickness (height of the side surface) and the thickness between the upper surface 32 or the lower surface 33 and the surface forming the cavity 34. But it can be used.

In addition to the block 31, for example, a structure having no cavity such as a concrete curb may be used as a rectangular block.

The support bracket 41 is configured as shown in FIGS. That is, a single metal plate having a band shape with a certain width is bent by pressing.

The support bracket 41 includes a fixing unit 42 fixed to the block 31 and a panel support unit 43 that is integrally formed with the fixing unit 42 and supports the solar cell panel 11.

The fixing unit 42 supports the panel support unit 43 and contacts the upper surface 32 of the block 31, and the upper load receiving unit 44 below the upper load receiving unit 44 via at least a part of the block 31. A lower load receiving portion 45 that faces the block 31 and that is in contact with the block 31, and a connecting integrated portion that integrates the lower load receiving portion 45 into the upper load receiving portion 44 with a gap below the upper load receiving portion 44. 46. The connection integrated portion 46 is formed at one end in the longitudinal direction of the upper load receiving portion 44 and the lower load receiving portion 45. For this reason, the other end has an opening 42a.

The lengths of the upper load receiving portion 44 and the lower load receiving portion 45 are preferably longer from the viewpoint of good fixed state. For example, the length may correspond to half the length of the upper surface 32 and the lower surface 33 of the block 31 in the short direction, in other words, half the length of the cavity 34 of the block 31. Further, the tip of the lower load receiving portion 45, that is, the end on the opening 42a side, may have a shape with a cut corner or a semicircular shape in plan view.

The connection integrated portion 46 is formed so that the lower load receiving portion 45 comes into surface contact with the lower surface 33 of the block 31 or the ceiling surface 34a of the cavity 34, or the thickness of the side surface of the block 31 or the cavity 34 from the upper surface 32 of the block 31. The length corresponding to the thickness up to the surface on which the film is formed is formed according to the size of the block 31 to be used and a desired fixing mode. Further, the connection integrated portion 46 is a flat plate shape, and an inner surface is a contact surface portion 46 a that contacts the flat side surface of the block 31.

The width of the fixing portion 42 is preferably wide from the viewpoint of the goodness of the fixed state. However, in order to allow the lower load receiving portion 45 to come into surface contact with the ceiling surface 34 a of the block 31, the cavity 34. Of the surfaces forming the upper surface 32, the width of the ceiling surface 34 a parallel to the upper surface 32 needs to be the same or narrower.

The panel support portion 43 is formed on the upper load receiving portion 44 from the end opposite to the connection integrated portion 46, and is formed on the upper end of the standing portion 47 to be fixed to the solar cell panel 11. The fixing portion 48 is provided. The fixing portion 48 is inclined with respect to the horizontal direction in accordance with the inclination of the solar cell panel 11 to be installed.

The standing part 47 and the fixing part 48 are flat. The standing portion 47 has a difference in length depending on whether it is the support fitting 41 used on the upper side in the inclination direction of the solar cell panel 11 or the support fitting 41 used on the lower side. That is, the upright portion 47 is formed longer in the support metal fitting 41 used on the upper side in the inclined direction than in the support metal fitting 41 used on the lower side. The lengths of the upright support metal 41 and the lower support metal 41 of the solar battery panel 11 are appropriately set according to the inclination angle of the solar battery panel 11 to be supported and the length in the inclination direction. .

As shown in FIGS. 4 and 5, the fixing portion 48 is a portion fixed to the projecting piece 15 of the aluminum frame 13 of the solar cell panel 11, and is folded back to the side having the fixing portion 42 in the standing portion 47. It is formed by bending at a predetermined angle. The fixing portion 48 is formed with a through hole 48a through which the bolt 51 for fixing is passed. A through hole 15 a corresponding to the through hole 48 a is formed in the protruding piece 15 of the aluminum frame 13. In FIG. 5, 52 is a nut to which the bolt 51 is screwed.

The ribs may be appropriately formed on the fixing unit 42 and the panel support unit 43 by punching or bending to improve the strength.

In the gantry 21 structure composed of the block 31 and the support bracket 41 as described above, for example, the solar cell panel 11 is installed as follows.

First, as shown in FIG. 6, the fixing portion 48 of the support metal fitting 41 is fixed to the predetermined position of the projecting piece 15 on the back surface of the aluminum frame 13 of the solar cell panel 11 with the bolts 51. When fixing, the two types of support metal fittings 41 having different lengths of the standing portion 47 are used properly on the upper side and the lower side in the inclination direction of the solar cell panel 11, and the solar cell has a predetermined direction, that is, the opening 42a side of the fixing unit 42. Align so that the panel 11 faces downward in the tilt direction.

Next, as shown in FIG. 7, the fixing portion 42 of the support bracket 41 on the back surface of the solar cell panel 11 is fixed to the block 31 arranged on the installation surface 18. When fixing the fixing unit 42 to the block 31, as shown in FIG. 8, the fixing unit 42 is relatively inserted into the block 31 from the side. 2, 3, and 8, the fixing portion 42 of the support bracket 41 is configured such that the lower load receiving portion 45 is in surface contact with the ceiling surface 34 a of the cavity 34 of the block 31. The load receiving portion 44 is inserted into the upper surface 32 of the block 31, and the lower load receiving portion 45 is inserted into surface contact with the ceiling surface 34 a of the cavity 34 of the block 31. When inserted, the upper load receiving portion 44 and the lower load receiving portion 45 sandwich the upper surface 32 of the block 31 and the ceiling surface 34 a of the cavity 34, that is, a part of the block 31. The contact surface portion 46a comes into contact with a part of the side surface of the block 31, and a fixed state is obtained by cooperation thereof.

When loose from the fixed state due to an error or the like, the fixed state can be adjusted by inserting a thin rubber sheet (not shown) between the fixing unit 42 and the block 31.

Alternatively, an adhesive may be applied to the block 31 or the fixing unit 42 and inserted to form an adhesive layer 55 between the fixing unit 42 and the block 31 as shown in FIG. The adhesive force of the adhesive layer 55 also acts to obtain a stronger fixed state. The formation of the adhesive layer 55 may be all or a part between the fixing unit 42 and the block 31.

When the lower load receiving portion 45 of the fixing portion 42 of the support metal fitting 41 is configured to come into surface contact with the lower surface 33 of the block 31, as shown in FIG. The lower load receiving portion 45 is inserted into the upper surface 32 of the block 31 so as to be in surface contact with the lower surface 33 of the block 31, that is, sandwiching the entire block 31. When inserted, the upper load receiving portion 44 and the lower load receiving portion 45 sandwich the upper surface 32 and the lower surface 33 of the block 31, and in addition, the contact surface portion 46 a of the connecting integrated portion 46 contacts a part of the side surface of the block 31. In contact with each other, the fixed state is obtained. Moreover, the lower receiving portion 45 receives a force in the compression direction due to the weight of the block 31, and the unity with the block 31 is also obtained by this pressing force.

Even when the lower load receiving portion 45 of the fixing portion 42 of the support metal fitting 41 is configured to come into surface contact with the ceiling surface 34a of the cavity 34 of the block 31, for example, as shown in FIG. With respect to the support bracket 41 on the upper side in the direction, the length of the connection integrated portion 46 is set to the length obtained by adding the thickness between the upper surface 32 of the block 31 and the ceiling surface 34 a of the cavity 34 to the thickness of one block 31. You can also The length of the erected portion 47 becomes shorter as the length of the connecting and integrating portion 46 becomes longer.

As described above, in such a gantry 21 structure, the solar battery panel 11 is installed by fixing the support metal fitting 41 to the block 31 and fixing the support metal fitting 41 to the solar battery panel 11, respectively. A commercially available block can be used for the block 31, and the support fitting 41 having the fixing portion 42 and the panel support portion 43 is formed by bending a single metal plate and has a simple configuration. Moreover, the fixing of the support metal fitting 41 to the block 31 only needs to be inserted, and the operation is easy. For this reason, installation of the solar cell panel 11 can be easily performed at low cost.

Further, the fixed state of the support metal fitting 41 with respect to the block 31 is held by contact resistance and clamping by the upper load receiving portion 44, the lower load receiving portion 45 and the coupling integrated portion 46 of the fixing portion 42. Since the connection integrated part 46 also has the contact surface part 46a, high integration with the block 31 is obtained. When the lower load receiving portion 45 is sandwiched between the lower surface 33 of the block 31, the weight of the block 31 is also helped and positioning is performed more strongly. For this reason, the stable installation state of the solar cell panel 11 can be obtained. When the lower load receiving portion 45 is in surface contact with the ceiling surface 34 a of the cavity 34 of the block 31, the lower load receiving portion 45 does not contact the installation surface 18, so that the lower load receiving portion 45 is corroded. Can be suppressed.

Further, when the support metal fitting 41 is fixed to the block 31, the connection integration portion 46 applies the load applied to the upper load receiving portion 44 to the lower load receiving portion 45 and the load applied to the lower load receiving portion 45. Since the load is reduced by dispersing in the upper load receiving portion 44, the durability is good and the installation state of the solar cell panel 11 can be maintained well.

As for the panel support portion 43 of the support bracket 41, the fixing portion 48 at the upper end of the standing portion 47 is bent in advance at a certain angle. Therefore, in this respect, the configuration is simple, the workability is good, and the strength is high. high. For this reason, in addition to the cost reduction of the support metal fitting 41 and the simplification of work, it contributes to the firm installation of the solar cell panel 11.

Other examples will be described below. In this description, parts that are the same as or equivalent to those in the above-described configuration are denoted by the same reference numerals and description thereof is omitted.

FIG. 12 is a cross-sectional view of the gantry 21. The support fitting shown in FIG. 12 is formed so that the orientation of the fixing portion 42 or the fixing portion 48 with respect to the standing portion 47 is different between the support fitting 41 on the upper side in the inclination direction of the solar cell panel 11 and the lower support fitting 41. It is a thing.

If the support metal fitting 41 is configured in this way, as shown in FIG. 12, the block 31 that is spaced apart from the upper side and the lower side in the inclination direction of the solar cell panel 11 is sandwiched when being fixed to the block 31. The fixing unit 42 can be fixed to the outer portion of the block 31. On the contrary, it can be fixed so as to face the inner part of the block 31.

In such a gantry 21 structure, for example, a part of the blocks 31 is embedded or fixed by another appropriate fixing means, and the positions of the blocks 31 that are spaced apart are positively fixed. When the distance is maintained, the fixing unit 42 is prevented from coming off from the block 31 and the installation state can be strongly held.

FIG. 13 is a cross-sectional view showing a fixed state of the support fitting 41 and the solar cell panel 11. The aluminum frame 13 of the solar cell panel 11 has the same structure as described above, but the fixing portion 48 of the support metal fitting 41 is integrally formed in a U-shaped cross section having an insertion piece 48b that enters the protruding piece 15 of the aluminum frame 13. Has been. A screw hole 48d having a female screw is formed in the receiving piece 48c facing the insertion piece 48b. The bolt 51 is held in the screw hole 48d. When the bolt 51 is tightened in a state where the insertion piece 48b is inserted inside the overhanging piece 15, the tip of the bolt 51 is pressed against the overhanging piece 15 of the aluminum frame 13 and inserted. The insertion state of the piece 48b is fixed.

In such a configuration, since it is not necessary to make a hole in the aluminum frame 13 of the solar cell panel 11, workability is further improved.

FIG. 14 is a cross-sectional view showing a fixed state of the support fitting 41 and the solar cell panel 11. The aluminum frame 13 of the solar cell panel 11 has the same structure as described above, but the fixing portion 48 of the support fitting 41 is integrally formed in a U-shaped cross section having an insertion piece 48e that enters the protruding piece 15 of the aluminum frame 13. Has been. The insertion piece 48e is thickened by folding, and is formed in a wedge shape that is thinner toward the distal end side. When the insertion piece 48e is strongly inserted inside the extension piece 15, the extension piece 15 is pinched between the receiving piece 48c facing the insertion piece 48e, and positioning with respect to the aluminum frame 13 is performed.

In such a configuration, it is possible to eliminate the need for bolting work on the aluminum frame 13 of the solar battery panel 11, so that workability is further improved.

FIG. 15 is a sectional view of the gantry 21. The support metal fitting 41 shown in FIG. 15 is the support metal fitting 41 set so that the orientation of the fixing portion 42 or the fixing portion 48 with respect to the standing portion 47 is different from the support metal fitting 41 shown in FIG. Further, the fixing portion 48 of the panel support 43 of the support fitting 41 has a wedge-shaped insertion piece 48e, like the fixing portion 48 shown in FIG.

Further, in addition to the support bracket 41, a connection member 49 that couples the support brackets 41 in a direction corresponding to the inclination direction of the solar cell panel 11 is provided. The connecting member 49 has a main body portion 49a that extends horizontally at both ends of the belt-shaped metal plate downward and has a superposed portion 49b that extends downward at both ends of the main body portion 49a. The length of the main body 49 a is a length that spans between the standing portions 47 of the support fittings 41 when the support fittings 41 are fixed to the upper and lower sides of the solar cell panel 11 in the inclination direction. As shown in FIG. 16, the width of the overlapping portion 49 b is the same as the width of the standing portion 47 of the support bracket 41, and the rising portions 49 c are bent at both side edges in the width direction. These rising portions 49 c sandwich the standing portion 47 of the support metal fitting 41.

A square hole 49d is formed at the center of the overlapping portion 49b, and a through hole 47a is formed at a position corresponding to the square hole 49d of the overlapping portion 49b in the standing portion 47. The square holes 49d and the through holes 47a are portions through which the fixing root bolts 57 are inserted and held. In the figure, 58 is a nut that is screwed onto the root angle bolt 57.

When the distance is maintained, the fixing unit 42 is prevented from coming off from the block 31 and the installation state can be strongly held. In addition, the connecting member 49 maintains the integrity of the support fittings 41 and firmly holds the fixed state of the fixing portion 48 with respect to the solar cell panel 11.

FIG. 17 is a cross-sectional view showing a state in which the support fitting 41 is fixed to the block 31. As shown in this figure, a spring portion 45 a having a U-shape in side view is formed on the lower load receiving portion 45 of the fixing portion 42 of the support fitting 41. The spring portion 45a is formed so as to be wider depending on the height of the cavity 34 as indicated by a virtual line in a normal state. The spring portion 45a may be formed of the same material as the lower load receiving portion 45 or may be formed of a separate member.

That is, the lower load receiving portion 45 is formed to be longer than the length of the block 31, and the extending portion 45b protrudes by an appropriate length before the surface opposite to the surface on which the contact surface portion 46a of the block 31 contacts. Yes. As shown in FIGS. 20 and 21, the vicinity of the base of the extended portion 45 b, specifically, the position ahead of and beyond the position that coincides with the surface on the opposite side of the surface on which the contact surface portion 46 a of the block 31 contacts. Also, a through hole 45c penetrating vertically is formed at a position on the contact surface portion 46a side. The width of the through hole 45 c is appropriately set according to the width of the lower load receiving portion 45.

The attached wedge member 45d is inserted into the through hole 45c from above. The wedge member 45d is formed of an appropriate plate material that is thick on one side (upper side).

Since the lower load receiving portion 45 and the wedge member 45d are provided as described above, the wedge member 45d functions to prevent it from coming off. For this reason, the support fitting 41 does not come off even if the block 31 is displaced and can maintain a stable fixed state. In addition, the work of attaching the support fitting 41 to the block 31 is very simple and quick because the wedge member 45d is inserted after the support fitting 41 is inserted into the block 31.

The panel support 43 of the support fitting 41 that supports the inclined lower end side of the solar cell panel 11 supports the inclined lower end 11a of the solar cell panel 11 in contact with the upper surface of the block 31. In other words, the panel support portion 43 has a structure in which the above-described standing portion 47 and the fixing portion 48 are integrated.

As shown in FIG. 21, the tip of the upper load receiving portion 44 of the support metal fitting 41 is substantially flat and has a length that does not reach the position where the solar cell panel 11 reaches the inclined lower end 11 a, and the inclined lower end 11 a is blocked by the block 31. It is set to a length that can be brought into close contact with the upper surface. An appropriate interposed member made of, for example, rubber may be provided between the block 31 and the inclined lower end 11a of the solar cell panel 11. In this case, the length of the upper load receiving portion 44 is set in consideration of the interposed member.

As shown in FIG. 20 and FIG. 21, a part of the width direction is formed to bulge out into a substantially triangular shape in a side view at the front end portion of the upper load receiving portion 44 in accordance with the inclination of the solar cell panel 11. A support portion 43 is formed. The panel support part 43 may bulge and form the whole in the width direction. The inclined surface of the panel support portion 43 has a square hole 43 a, and a root angle bolt 53 is inserted and held from below, and the solar battery panel 11 is fixed by a nut 52 that is screwed to the root angle bolt 53.

When such a panel support portion 43 is provided, the inclined lower end 11a of the solar cell panel 11 is in close contact with the upper surface of the block 31 so that the load is supported not only by the support fitting 41 but also by the block 31, so that high stability is achieved. can get.

In addition, since the panel support portion 43 of the support fitting 41 can be obtained by bulging and forming by pressing, strength can be obtained even if it is thinner than the case where the standing portion 47 having a structure for extending the piece is provided. Processing is also easy. For this reason, it is possible to obtain a good fixed state while reducing the cost.
