  An object of the present invention is to provide an installation structure and an installation method capable of supporting and attaching a solar panel efficiently and surely regardless of the thickness and weight of the solar panel.

The present invention comprises a plurality of rail support members fixed to a base material, a slide rail fixed to the plurality of rail support members, and a panel rail provided on the back surface of the solar panel, The solar panel is arranged at an installation position by fitting the panel rail to the slide rail and sliding the panel rail in the longitudinal direction of the both rails with respect to the slide rail. In the installation structure, a plurality of the panel rails are arranged at intervals in the left-right direction of the solar panel, and the panel rail includes a rail top portion fixed to the solar panel, and the rail top portion. A truss portion extending downward from the rail, and a rail engagement slidably engaged with the slide rail The truss portion extends obliquely downward from the top of the rail, and in one solar panel, the truss portion of one of the panel rails is the other arranged in the lateral direction. A solar panel installation structure is provided that constitutes a truss structure in relation to the truss portion of the panel rail.

The slide rail includes a slide top portion fixed to the upper surface of the support portion of the rail support member, and slide side portions disposed on both sides of the slide top portion. The panel rail includes outer rails disposed on both left and right sides of the solar panel. The outer rail includes a rail top fixed to the solar panel, a truss extending downward from the rail top, and a lateral extension from a lower portion of the truss to contact the slide top. A rail top part and a rail engagement part extended from the outer rail top part and slidably engaged with the slide side part are provided.

And the said truss part extends diagonally so that it may go to the center of the said solar panel as it goes below. In other words, the truss portion of the outer rail extends obliquely from the rail top toward the inner lower side. Therefore, it does not protrude from the rail top. As a result, even when the solar panels are arranged side by side, the solar panels can be smoothly slid and installed without interfering with the adjacent solar panels without increasing the spacing between the solar panels. In addition, since the truss portion extends obliquely inward and downward, a single solar panel can form a truss structure in relation to other truss portions arranged side by side. A strong support structure is realized against the wind pressure applied to this.

Furthermore, the panel rail can also be provided with a middle rail disposed between the outer rails on the left and right sides, so that it can be safely supported even in a large-sized and heavy solar panel. . The middle rail includes a rail top fixed to the back surface of the solar panel, a truss extending downward from the rail top, and a lateral extension from a lower portion of the truss to the slide top. The rail top part which contact | abuts, and the rail engaging part extended from the said rail top part and engaged with the said slide side part so that a slide is possible. The truss portion of the middle rail extends obliquely, and the direction in which the truss portion extends obliquely is opposite in the left-right direction with respect to the outer rail or the middle rail that extends with the truss. It extends in the direction. As a result, in a single solar panel, a truss structure can be formed in relation to the truss parts arranged side by side. Therefore, a strong support structure can be provided against the solar panel's own weight and the wind pressure applied to it. Realize.

In this case, the middle rail can integrally form the rail top portion, the pair of left and right truss portions, the pair of left and right rail tops, and the pair of left and right rail engaging portions. The pair of left and right truss portions extend obliquely away from each other as they go downward. In other words, the middle rail can be implemented with an integrated metal fitting or the like that forms a substantially trapezoidal shape, and the left and right truss portions that constitute the hypotenuse of the trapezoid form a truss structure and are arranged adjacent to the left and right. The outer rail or the middle rail extends in a direction opposite to the truss extending in the left-right direction. Therefore, a plurality of truss portions that support one solar panel constitute a truss structure, and a strong support structure can be realized.

In addition, since the fixing portion of the slide rail to the rail support member is below the truss portion, for example, even when the fixing is performed with a screw, the truss portion that extends obliquely has a head portion of the screw or the like. Can be avoided. Therefore, even if it is a seam joint of a roof having a small mounting area, it is possible to realize a secure fixing without difficulty.

Further, the roof is a folded plate roof provided with a seam joint, and the rail support member includes a support ceiling disposed at an upper part of the seam joint, and a lower side from both sides of the support ceiling. A support side portion that is extended to the side, and one of the support side portions includes a support contact portion that contacts the helical joint portion, and the other support side portion includes a tightening bolt. By tightening, the joint portion can be sandwiched between the support contact portion and the tightening bolt. According to this structure, construction can be performed without penetrating a hole or a screw through the roof, and there is no possibility of rain leakage due to the installation of the solar panel.

Further, the slide side portion of the slide rail is extended downward from both sides of the slide top portion, and the rail engagement portion is extended downward from an end of the rail top portion and the slide The rail side part which contact | abuts the outer side of a side part and the rail folding | turning part extended upwards from the lower part of the said rail side part and arrange | positioned inside the said slide side part can also be provided. Accordingly, it is possible to realize an installation structure that has a simple structure and exhibits sufficient strength even when wind pressure or the like is received from below or from the side without impairing the smoothness of the slide.

Furthermore, the present invention relates to a method of fixing a rail to a roof having a seam joint, and installing a plurality of solar panels through the rail according to the above installation structure. Fixing the rail support member, fixing the slide rail to the rail support member, fixing the panel rail to the back surface of the solar panel, and attaching the panel rail to the slide rail And a method of installing a solar panel comprising: fitting and sliding the panel rail in the longitudinal direction of both rails with respect to the slide rail, and placing the panel rail at an installation position of the solar panel. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Outline) An outline of a solar panel installation method according to this embodiment will be described first.
This installation method includes the following steps.
(1) Rail support member fixing step (2) Slide rail fixing step (3) Panel rail fixing step (4) Slide fixing step

(1) The step of fixing the rail support member is a step of attaching the rail support member 21 to the roof (folded plate roof 11 in this example). In this example, the rail support member 11 is formed on the folded plate roof 11 at regular intervals. This is a step of fixing the rail support member 21 to the joint portion 12.
(2) The slide rail fixing step is a step of fixing the slide rail 31 to the rail support member 21.
(3) The panel rail fixing step is a step of fixing the outer rail 41 to the back surface of the solar panel 13.
(4) The slide fixing step is a step of fitting the panel rail 40 to the slide rail 31, sliding the panel rail 40 in the longitudinal direction of both rails with respect to the slide rail 31, and arranging the panel rail 40 at the installation position of the solar panel 13. It is.

(1) Rail support member fixing step (FIGS. 1, 6, and 7)
The rail support member 21 is attached to the roof (in this example, the folded plate roof 11 provided with the seam 12). The splice portion 12 is a connecting portion between the steel plates constituting the folded plate roof 11, and is connected by bending the two adjacent folded plate members 14 made of steel plates together in an inverted L shape. Has been.

The rail support members 21 are attached at appropriate intervals in the longitudinal direction of the joint portion 12. For example, in the case of the solar panel 13 shown in FIGS. 4 and 5, when the height is less than 1500 mm × width less than 1000 mm, it is appropriate to provide the front, middle, and rear three at intervals of about 750 mm. Four or more solar panels 13 may be arranged, or two or one.

As shown in FIGS. 6 and 7, the rail support member 21 includes a support top portion 22 disposed on the top of the joint portion 12, and a support side portion extended downward from the left and right sides of the support top portion 22. 23. One (left side in the figure) support side portion 23 includes a support contact portion 24 that contacts the left side surface of the joint portion 12. The support contact portion 24 extends laterally (leftward in the drawing) from the lower end of the support side portion 23 so as to be able to contact the bent portion of the inverted L-shaped joint portion 12. The other (right side of the figure) support side portion 23 includes a bolt receiving portion 25. The bolt receiving portion 25 is a female screw hole formed in the support side portion 23 and is screwed into the fastening bolt 26. In FIG. 6B and FIG. 7B, in order to clarify the relationship between the members, a blank portion is drawn between the members that are in contact with each other.

At the time of mounting, the fastening abutting portion 24 of the rail support member 21 is brought into contact with a substantially L-shaped bent portion from the left side surface of the joint portion 12 and the fastening bolt 26 screwed into the supporting side portion 23 is attached. The tip is brought into contact with the right side surface of the joint portion 12 and tightened. Accordingly, the joint portion 12 is sandwiched and fixed between the support contact portion 24 and the tightening bolt 26, and the rail support member 21 is not directly processed on the folded plate roof 11. Can be attached.

(2) Slide rail fixing process (FIGS. 2, 6, and 7)
This is a step of fixing the slide rail 31 to the rail support member 21. In this example, the slide rail 31 is fixed to the rail support member 21 using the slide rail fixture 34. The slide rail 31 is a U-shaped metal member that extends in the longitudinal direction of the joint portion 12 and can be manufactured by extrusion or the like, or even if a long plate material is bent. Can be manufactured. The slide rail 31 includes a flat plate-like slide top portion 32 that extends in the longitudinal direction of the joint portion 12 and a slide side portion 33 that extends downward from the left and right sides of the slide top portion 32.

At the time of attachment, the slide top 32 is placed on the support top 22 of the rail support member 21 described above, and the support top 22 and the slide top 32 are fixed by a slide rail fixture 34 such as a tapping screw. To do. In this example, the number of fixing points is two on the left and right sides of the joint portion 12. However, the number of fixing points may be four or the like, and can be changed to a suitable number. Further, the slide rail fixture 34 may be a rivet or a weld in addition to the tapping screw.

(3) Panel rail fixing process (FIGS. 3, 5, 6, and 7)
This is a step of fixing the panel rail 40 (outer rail 41, inner rail 51) to the back surface of the solar panel 13.

First, a rectangular outer frame 18 such as an amylmium frame is provided on the front, rear, left, and right outer peripheries of the solar panel 13, and a reinforcing material 17 is passed to the back surface of the solar panel 13 in the lateral direction as necessary. The reinforcing member 17 can be a square member or a channel member made of aluminum. In this example, a long member having a cross section “E” shape is used.

As shown in FIG. 3, the number of reinforcing members 17 may be an appropriate number necessary for reinforcement, but in this example, three reinforcing members 17 are arranged. The panel rail 40 is disposed in the front-rear direction of the solar panel 13, the outer rail 41 is disposed along the left and right outer frames 18 of the solar panel 13, and the inner rail 51 is between the front and rear outer frames 18. In the vertical direction at the center of the solar panel 13. When the overall strength is secured, the inner rail 51 can be omitted, and conversely, when there is anxiety in strength, two or more rails may be arranged. As shown in FIG. 3B, when the electric wiring box 15 is arranged on the back surface of the joint portion 12, the length of the inner rail 51 may be shortened by avoiding this, Further, this may be avoided in the left-right direction. The panel rail 40 is fixed to the reinforcing member 17 or the main body of the solar panel 13 by a slide rail fixture 16 such as a tapping screw. In this example, the number of fixing points is two for each reinforcing member 17, but may be four or the like, and can be changed to a suitable number. Further, the slide rail fixture 16 may be a rivet or a weld in addition to the tapping screw.

The outer rail 41 includes a rail top portion 42, a truss portion 43, a rail top portion 44, and a rail engagement portion 45. The rail top portion 42 is a portion that is fixed to the solar panel 13 (in this example, the reinforcing member 17) by the slide rail fixture 16. The truss portion 43 is a portion that extends downward from the rail top portion 42, and the rail top portion 44 is a portion that extends laterally from the lower portion of the truss portion 43 and contacts the slide top portion 32 of the slide rail 31. . The rail engaging portion 45 is a portion that extends from the rail top portion 44 and engages with the slide side portion 33 so as to be slidable.

In this example, the tip of the rail top portion 42 is bent upward to form a rail rising portion 48, which is along the side end surface of the solar panel 13 or the reinforcing material 17, but this rail rising portion 48 is omitted. It can also be implemented. The rail engagement portion 45 extends downward from the end of the rail top portion 44 and contacts the outside of the slide side portion 33, and extends upward from the lower portion of the rail side portion 46 and slide side portion 33. The rail folding | returning part 47 arrange | positioned inside is provided. The truss portion 43 is inclined so as to extend obliquely toward the inner side (center direction of the panel rail 40) as it goes downward.

The inner rail 51 includes a rail top portion 52, a pair of left and right truss portions 53, a pair of left and right rail top portions 54, and a pair of left and right rail engaging portions 55. The rail top portion 52 is a portion that is fixed to the solar panel 13 (in this example, the reinforcing member 17) by the slide rail fixture 16. The truss portion 53 is a portion that extends downward from the left and right ends of the rail top portion 52, and the rail top portion 54 extends laterally from the lower portion of the truss portion 53 and abuts against the slide top portion 32 of the slide rail 31. Part. The rail engaging portion 55 is a portion that extends from the rail top portion 54 and engages with the slide side portion 33 so as to be slidable.

As described above, the inner rail 51 is integrally formed in a trapezoidal shape having a symmetrical cross section, and is fixed by the slide rail fixture 16 at one central portion of the rail top 52. However, the left and right may be constituted by separate members, and the left and right may be fixed by separate slide rail fixtures 16. The left and right truss portions 53 are inclined in a direction away from each other as they go from the upper side to the lower side.

(4) Slide fixing process (FIGS. 4 and 5)
In the slide fixing step, the panel rails 40 (the outer rail 41 and the inner rail 51) fixed to the back surface of the solar panel 13 as described above are fitted to the slide rail 31, and the panel rails 40 are both attached to the slide rail 31. This is a step of sliding in the longitudinal direction of the rail and arranging it at the installation position of the solar panel 13.

When the folded-plate roof 11 is inclined, it is desirable from the viewpoint of workability to fit and slide from the upper side to the lower side on the water, but it can also be inserted from the opposite direction. A plurality of solar panels 13 can be inserted one after another along the longitudinal direction of the slide rail 31, and the number can be changed as appropriate according to the size of the construction site. Further, the slide rail 31 is arranged in a plurality in the horizontal direction, and a plurality of solar panels 13 can be arranged side by side, and a large number of solar panels 13 can be efficiently installed over a wide area. Can do.

In addition, if the edge part (upper end and lower end) of the solar panel 13 of each row | line | column is fixed by appropriate fixing materials (not shown), such as passing a bar material etc., it will be individual to the intermediate | middle solar panel 13. There is no need to provide fixing means.

(Truss Structure) As shown in FIG. 5, in the completed installation structure, the truss structure 43 is constituted by the truss portion 43 of the outer rail 41 and the truss portion 53 of the inner rail 51. The truss portion 43 of the outer rail 41 extends obliquely toward the center of the solar panel 13 as it goes downward. In other words, since the truss portion 43 extends obliquely inward and downward, the truss portion 43 does not protrude from the rail top portion 42, and even when the solar panels 13 are arranged side by side, the space between the solar panels 13 is not large (specifically In other words, even if it is 20 mm or less, it is possible if it does not come into contact), and it can be installed by sliding smoothly without interfering with the adjacent solar panel 13.

Since the truss portion 43 of the outer rail 41 extends obliquely inward and downward, a single solar panel 13 can form a truss structure in relation to other truss portions 43 and truss portions 53 that are arranged horizontally. it can. Specifically, from right to left in FIG. 5, the truss portion 43 of the outer rail 41 at the left end of the solar panel 13 is inclined downward to the right, and the left truss portion 53 of the central inner rail 51 is upward to the right. The right truss portion 53 of the central inner rail 51 is inclined downward and the truss portion 43 of the outer rail 41 at the right end of the solar panel 13 is inclined upward. Thus, in one solar panel 13, a truss structure is constituted by truss portions 43 and 53 provided on different panel rails 40 (outer rail 41 and inner rail 51). As a result, a strong support structure can be realized even with respect to the weight of the solar panel 13 and the wind pressure applied thereto.

In this example, it is assumed that the inner rail 51 is provided, and even if it is a large-sized solar panel having a large weight, it can be supported so as not to bend even if it receives a wind pressure safely. It is also possible to further increase the number 51, and in the case of a small solar panel, the inner rail 51 can be omitted. Even when the truss portion 43 is omitted, the truss portion 43 of the outer rail 41 at the left end of the solar panel 13 is inclined downward and the truss portion 43 of the outer rail 41 at the right end of the solar panel 13 is inclined upward. The structure is maintained. As for the direction of the inclination, it is desirable that the right upward and the right downward are alternately arranged. However, as described above, two right upwards are arranged continuously and two right downwards are arranged next to it. It is only necessary to maintain the truss structure. The inclination angle of the rail engaging portion 45 degrees is appropriate, but it can be changed to 30 to 60 degrees. Contrary to the illustrated example, the truss portion 43 of the outer rail 41 at the left end of the solar panel 13 is inclined downward to the left, and the truss portion 43 of the outer rail 41 at the right end of the solar panel 13 is inclined upward to the left. Further, the truss portion 53 of the middle rail 51 can also be implemented as extending in the opposite direction in the left-right direction to the illustrated one.

The slide rail fixture 34 that fixes the rail support member 21 and the slide rail 31 is formed below the truss portion 43 of the outer rail 41 or the truss portion 53 of the inner rail 51. Therefore, even if the screw head of the slide rail fixture 34 protrudes slightly upward, the truss portion 43 and the truss portion 53 can avoid the screw head and the like, and the possibility of interference is suppressed. Therefore, even if the rail support member 21, the slide rail 31, and the panel rail 40 are not made large, it is possible to realize a reliable and compact fixation without difficulty. In addition, the rail engagement portion 45 includes the rail side portion 46 and the rail turn-back portion 47, so that even when wind pressure or the like is received from below or from the side without impairing the smoothness of the slide. The installation structure showing sufficient strength could be realized.

The solar panel to be attached may have a relatively large thickness as shown in the illustrated embodiment, but a sheet-like solar panel as shown in Patent Document 3 is arranged on the steel plate. It may be relatively thin. Further, in the embodiment, the example of fixing to the roof having the seam joint portion has been shown. However, the present invention is not limited to this, and various basic materials such as various forms of roofs, horizontal rooftops, vertical or inclined wall surfaces, and ground. Can be implemented as a fixed structure.
