However, with such a structure, it is impossible to firmly attach the photovoltaic power generation panel to the inclined roof, and when installing the photovoltaic power generation panel later in a second-hand house, it is necessary to install the support bolts. However, if the mounting position of the support bolt is incorrect, it cannot be handled.
In particular, not only Japanese roof tiles, but also various types of roof tiles such as Spanish roof tiles and Ryukyu tiles, and various types such as slate thatched roofs, such a mounting structure that can handle different roofing materials is desired. .
The technical problem of the present invention pays attention to such a problem, and it is possible to firmly attach a photovoltaic power generation panel even on a roof inclined like a tile roof, and the mounting position of the support bolt varies depending on the roofing material. However, it is to realize a structure that can cope.

In the first aspect of the present invention, the support bolt standing on the roof is gripped by a U-shaped presser bar from above and below in a state where the support bolt is inserted into a slit formed in the slope direction of the roof on a frame on which the photovoltaic power generation panel is attached. This is a solar panel mounting structure that is fastened and fixed with nuts attached to the base. Since there is a slit through which the support bolt penetrates, the base is slid to align and then fixed.

In the second aspect, only three types of lengths for the first stage, two stages, and three stages are prepared, and the other stages are connected to the existing minimum length. The solar panel mounting structure according to claim 1, wherein the structure is increased.

3. The photovoltaic power generation according to claim 1 or 2, wherein the U-shaped presser bar is formed in a hemispherical shape with a bolt insertion hole as a center to make the strength strong. Panel mounting structure.

According to a fourth aspect of the present invention, in the case of roofing, a bolt hole through which the support bolt can be penetrated is opened at the highest portion of the roof tile, and an auxiliary rafter supported by a rafter is provided at a portion without a rafter to raise the support bolt. The solar power panel mounting structure according to claim 1, claim 2, or claim 3.

In a fifth aspect of the present invention, in a slate-roofed roof, a portion without a rafter is provided with a reinforcing plate on the slate, and the support bolt is erected on the reinforcing plate. Or it is the attachment structure of the photovoltaic power generation panel of Claim 3.

According to a sixth aspect of the present invention, the bolt insertion hole of the crank-type holding band that holds the upper end or the lower end in the gradient direction of the photovoltaic power generation panel is used as a slit hole perpendicular to the gradient, and the crank-type holding band is held down. The mounting structure for a photovoltaic power generation panel according to any one of claims 1 to 5, wherein the seat has a square L shape.

According to the seventh aspect of the present invention, the middle portion between the upper end and the lower end in the gradient direction of the photovoltaic power generation panel is pressed at a time with a double press that is a groove type by integrating the crank-type press band ridges back to back and opens at the bottom of the groove. The structure for mounting a photovoltaic power generation panel according to any one of claims 1 to 6, wherein the bolt insertion hole is a slit hole in a direction perpendicular to the gradient, and the presser seat has a square shape. It is.

According to the first aspect, since the pedestal is slid and aligned and then fixed to the support bolt, the alignment of the photovoltaic power generation panel and the pedestal is easy and workability is good. Therefore, even if the mounting position of the support bolt varies, it is possible to easily cope with the gradient direction.

As in claim 2, if the length of the gantry is prepared only for the first stage, the second stage, and the third stage, the other large stages have the existing minimum length. It can be realized by connecting and increasing, and it is not necessary to prepare a large base and does not require a wide space.

As described in claim 3, the U-shaped presser bar is formed in a hemispherical shape centered on the bolt insertion hole, and the strength is made strong, thereby preventing the warp of the U-shaped presser bar and fixing firmly. .

As in claim 4, in the case of roofing, a bolt hole through which the support bolt can be penetrated is opened at the highest part where rainwater does not collect easily, so it is possible to easily take measures against rain leakage by caulking or sandwiching an elastic material. .
Moreover, since the auxiliary rafters supported by the rafters are provided and the support bolts are raised at the site without the rafters, the support bolts can be raised at an arbitrary position.

As for the part without the rafters on the roof of the slate, the support bolt can be set up at an arbitrary position by providing the reinforcing plate on the slate as in claim 5 and setting up the support bolt on the reinforcing plate. it can.

Since the bolt insertion hole of the crank-type holding band that holds the upper end or the lower end in the gradient direction of the photovoltaic power generation panel is made into a slit hole in a direction perpendicular to the gradient as in claim 6, it is perpendicular to the gradient of the roof. In addition, the position of the crank-type press band can be positioned so as to match the upper end or the lower end of the photovoltaic power generation panel. Therefore, no trouble occurs even if the mounting position of the support bolt is a little out of place or mixed.
In addition, since the seat cap for holding the crank-type pressing band is formed in a square L shape, the contact area with the crank-type pressing band with a slit hole is increased, and the pressing is ensured. Since the seat hook is L-shaped, it is easy to align by overlapping the crank-type holding band.

As in claim 7, the middle between the upper end and the lower end in the gradient direction of the photovoltaic power generation panel is pressed at once with a double press that has a crank-type press band that is integrated back to back and formed into a groove shape. Since the bolt insertion hole to be opened is a slit hole in a direction perpendicular to the gradient, it can be positioned in the direction perpendicular to the gradient of the roof so that the position of the groove-shaped double presser matches the intermediate position of the photovoltaic power generation panel. Therefore, even if the mounting position of the support bolt is a little inaccurate or mixed, no trouble occurs.
In addition, since the double presser seat with a slit at the groove bottom has a square shape, the contact area between the double presser with a slit hole and the seat spring increases, and the double presser with a slit at the groove bottom is securely fixed. It becomes.

Next, an embodiment will be described in detail how the mounting structure of the photovoltaic power generation panel according to the present invention is actually realized. FIG. 1 is a front view of an example using tiles as a roofing material, and FIG. 2 is a side view thereof. 1... Are rafters used when wiping the roof, are usually arranged at intervals of about 45 cm, and are inclined so that the ridge side becomes higher.
It is sufficient if the support bolts of the photovoltaic power generation panel can be set up directly above the rafters 1..., But they often deviate from the position of the rafters 1. A 5 cm auxiliary rafter 2 is provided.

The auxiliary rafter 2 is attached in advance as shown in FIG. 3 only at the position where the support bolt B is to be disposed. That is, with the L-shaped metal fitting L fixed to the side surfaces of the rafter 1 and the auxiliary rafter 2 with wooden screws 3 and nails, as shown in FIG. 1 and FIG. From above, a plurality of locations near the outer periphery of the support rod 6 are fixed to the upper surface of the auxiliary rafter 2 with wooden screws 7 or nails.
In addition, since the auxiliary rafter 2 can be attached also from the attic, it can be applied to other than when a new roof is constructed.

As shown in FIG. 4, in the state where the center of the support rod 6 is pressed and partially extruded on the upper side, a hole through which the support bolt B passes is formed in the extruded portion, the female screw is cut, and the support bolt B is screwed from below. At the same time, the nut 7, the lower presser U-shaped hook 8, the slide type photovoltaic power generation panel mounting base 9, the upper presser U-shaped hook 10, and the nut 11 are inserted in this order. W is a washer.

After the support bolt B is inserted into the bolt hole and the cap 13 which are opened in advance in the roof tile 12, the components shown in FIG. The cap 13 is a ring-shaped body made of an elastic material such as chloroprene rubber so that it does not leak from the bolt holes of the roof tile 12. The cap 13 may be molded according to the convex surface of the top surface of the roof tile 12, but is highly elastic. In some cases, it may be elastically deformed into a shape that conforms to the convex surface.
In addition, rain leakage can be reliably prevented by filling the space between the bolt hole of the roof tile 12 and the support bolt B with a caulking material, or caulking the outer periphery of the ring-shaped cap 13 to fill the gap with the roof tile 12.
In this way, the roof 12 is caulked between the roof tile 12 and the support bolt B, or the elastic ring-shaped cap 13 is placed on the roof of the roof tile, so that the load is concentrated on the roof tile 12 or the support bolt B in the event of an earthquake or the like. It is possible to prevent the roof tile 12 from being broken by the force from the side.

The base 9 for mounting the photovoltaic power generation panel is slid in a state where it is loosely sandwiched between the lower presser U-shaped 鈑 8 and the upper presser U-shaped 鈑 10, and is adjusted to the mounting position of the photovoltaic power generation panel. Then, tighten the upper nut 11 to fix it.
Therefore, the upper end of the bolt protrudes from the gantry 9 made of C-shaped steel.
5 (1) and (3) are a plan view and a side view of the gantry 9, and the support bolt B slides relatively in the slit s opened in the roof slope direction on the ceiling surface of the gantry 9 with the C-shaped steel lying down. It is possible. H is a bolt hole, the central bolt hole H is for inserting the bolt of FIG. 8, and the bolt hole H at the left end is for inserting the bolt of FIG.
FIG. 6 is a plan view and a side view of a state in which such a gantry 9 is installed and a photovoltaic power generation panel can be laid, and the joint fitting 14 is attached and connected to the side surface in order to expand in the gradient direction. It is. The bolt hole 14h in FIG. 5 (3) is for mounting the joint fitting 14. The bolt hole 17h in FIG. 5 (1) is for mounting the joint fitting 17.

One solar power generation panel is laid by attaching two sets of support bolts B as shown in the figure to the gradient direction of the roof. In practice, however, the gantry 9 has such a length that a plurality of photovoltaic panels can be placed so that a plurality of photovoltaic panels can be laid. use.
The left and right pairs of the gantry 9 are attached to the roof as described above, and laid by placing the photovoltaic power generation panel P on the gantry 9. Accordingly, in the embodiment shown in FIG. 6, since four rows are laid in the left and right rows and in the gradient direction, a total of eight photovoltaic power generation panels can be laid.
In addition, when installing a photovoltaic power generation panel in a direction perpendicular to the roof slope, the upper and lower joint brackets 17 are attached and connected to the inner sides of the left and right crank-type pressing strips 15 and 15.

The lower end and the upper end of the photovoltaic power generation panel P in the gradient direction are pressed by a crank-type press band 15 as shown in FIGS.
The band 15 is formed in a crank shape as shown in FIG. 7 (2) and has a skirt portion 151 to be blinded, and conceals the base 9 made of C-shaped steel.
A long slit 15s of 5 to 25 cm is formed in the attachment side 152 of the crank-type pressing band 15 in the direction perpendicular to the slope direction of the roof. In addition, 153 is a rising part and 154 is a panel presser.

A square seat 22 is formed integrally with an L-shaped portion 23 that overlaps the skirt portion 151. In this way, since the counterspindle 22 is square, the contact area with the attachment side 152 of the crank-type pressing band 15 with the slit 15s is large, and it can be firmly and securely fixed. Moreover, since it is formed in the L shape, the square seat 22 can be easily positioned by overlapping the skirt portion 151. The normal circular washer W may be omitted or used in combination.
Thus, in the direction perpendicular to the slope of the roof, the slit 15s as long as 5 to 25 cm is formed in the attachment side 152 of the crank-type presser band 15, so that about 1 to 2 peaks of the tile are also supported by the support bolt B. Even if the mounting position is out of position, it can be easily handled, and the construction becomes simple. Further, even if the strength is reduced due to the formation of the long slit 15s, the L-shaped seat spring 22 is reinforced.
In addition, since the drain hole h is formed in the concave corner portion of the crank-type presser band, rainwater does not accumulate particularly when pressing the upper end of the photovoltaic power generation panel P in the gradient direction.

In the middle of the gradient direction, as shown in FIG. 8, the crank-type press band 15 is integrated with the back-to-back and is pressed by a double presser 16 that is a groove type. That is, the lower end and the upper end of the panels P and P adjacent to each other in the gradient direction are pressed by one component 16 at a time.
The bolt insertion hole opened in the groove bottom of the double presser 16 is a slit hole 16s of 5 to 25 cm, and the presser seat spring 24 has a square shape. Therefore, even in a direction perpendicular to the slope of the roof, it can be easily positioned so that the position of the groove-shaped double presser 16 matches the intermediate position of the photovoltaic power generation panel P, and there is no problem even if the mounting position of the support bolt B is slightly deviated. Does not occur.

Since the presser base 24 has a square shape, the contact area between the double presser 16 with the slit hole 16s and the base 24 increases, and the double presser 16 having the slit 16s at the groove bottom is securely fixed and firmly fixed. it can.
In addition, since it is unsightly if the photovoltaic power generation panels P and P adjacent to the upper and lower sides and the ends of the double presser 16 are not aligned, the vertical walls that are in contact with both ends of the double presser 16 so as to be forcibly aligned And a bottom plate 25 that is screwed under the double presser 16 and is screwed, and a forcing plate formed in an L shape.
In this way, the displacement can be absorbed by slits s in the gradient direction and slits 15s and 16s in the direction perpendicular to the gradient, so that play can be done in each direction in the event of an earthquake, and destruction can be prevented in the event of an emergency. It is ideal for Japan, an earthquake-prone country.
Since the panel holders 15 and 16 are manufactured in accordance with the size of the photovoltaic power generation panel, they are connected by a joint fitting 17 when laying a plurality of rows of photovoltaic power generation panels.

FIG. 9 and subsequent figures show a construction method suitable for a slate roofing roof. A reinforcing plate 19 made of a companion veneer plate or the like is stacked on a slate roofing material 18 as shown in FIG. Fix the left and right with wooden screws 20. Note that the caulking material 21 prevents rain leakage around the reinforcing plate 19.
Next, the support rod 6 with the waterproof tape t made of butyl or the like attached to the lower surface is fixed to the reinforcing plate 19 with wooden screws or nails.
The support bolt B is inserted into the nut 7, washer W, lower presser U-shaped 鈑 8, slide type photovoltaic power generation panel mounting base 9, upper presser U-shaped 鈑 10, washer W, nut 11, and temporarily fixed. Then, after the base 9 is slid and aligned, the upper nut 11 is tightened and fixed.
Thus, in the case of a slate thatched roof, since the support bolt is raised on the slate, it can be applied regardless of whether it is newly built or used.

The lower presser U-shaped 鈑 8 and upper presser U-shaped 鈑 10 are warped as shown in Fig. 12 (1) when the nut 11 is tightened by simply forming the U-shaped U-shaped 鈑 10. There is a problem that it cannot be gripped.
In order to prevent this, as shown in FIG. 12 (2), it is desirable to strengthen the strength by forming a hemispherical shape around the bolt hole H at the center of the U-shaped presser rods 8 and 10. That is, the space between the bolt hole H and the part that holds the gantry 9 is formed in a hemispherical shape to increase the strength. As a result, the nut 11 can be tightened sufficiently.

As described above, according to the present invention, it is possible to securely attach a photovoltaic power generation panel even on a roof inclined like a tiled roof, and even when installing a photovoltaic power generation panel later in a second-hand house, it is rough. The alignment is sufficient, and the spread of solar power generation is further promoted in Japan, where there are many typhoons and earthquakes.
