Since the metal fittings 13L and 13R can be configured, there is an effect that work efficiency is improved.

In particular, when the pair of identical metal parts 13 and 13 are put together and the downward hook 25a and the upward hook 25b are engaged with each other, the hooks 25a and 25b are engaged with each other in the vertical direction. It is possible to connect in a non-movable manner in the X direction and the Y direction. Further, the hook 25b extending in the X direction is used as a support shaft, and the hook 25a extending in the Y direction is pivotally connected around the support shaft. Can do.

Since the pair of identical metal parts 13 and 13 are suitably assembled even when the fastening bolts 15 are not inserted due to the meshing from above and below, the metal parts 13 and 13 are inserted thereafter. The operation of inserting the fastening bolt 15 into the hole 17 is facilitated.

According to the second aspect of the present invention, the same component fitting 13 includes the lateral ribs 23 and the longitudinal ribs 24 a and 24 b, and corresponds to one side portion of both side portions of the main body portion 18 in the X direction. Since the X-direction hook 25b extends from the end of the lateral rib 20, and the Y-direction hook 25a extends from the vertical rib 24a corresponding to the other side, a relatively complicated configuration is obtained. Although it is a metal fitting, there is an effect that it becomes possible to manufacture by punching and pressing one metal plate.

According to the third aspect of the present invention, the first vertical ribs 24a provided on both sides of the main body 18 with respect to the distance from the central axis Ax of the fastening bolt 15 inserted through the clamping fittings 13L and 13R. The second vertical rib 24b has a distance L1 from the inner surface of the first vertical rib 24a provided with the downward hook 25a to the central axis Ax, and a distance L2 from the outer surface of the second vertical rib 24b to the central axis Ax. L1> L2. As a result, when the pair of the clamp fittings 13L and 13R are put together and the downward hook 25a and the upward hook 25b are engaged with each other on both sides of the clamps, the first vertical rib of one clamp fitting The downward hook 25a provided on 24a can be overlapped with the outer surface of the second vertical rib 24b of the other clamp. As a result, the pair of sandwiching brackets 13L and 13R does not cause positional displacement or rattling in the X direction with each other while the downward hooks 25a and 25a hold the second ribs 24b and 24b. Since the guide bolts 15 are preferably guided in the Y direction by tightening the fastening bolts 15, it is possible to clamp the flange 1a at an accurate position.

According to the fourth aspect of the present invention, the downward hook 25a is configured by providing the downward flange portion 39 at the tip of the arm portion 38 extending in the Y direction from the first vertical rib 24a. A protrusion 40 protrudes downward from the first vertical rib 24a in the Y direction, and a guide surface 40a toward the arm portion 38 is formed at the tip of the protrusion 40. The upward hook 25b extends in the X direction. It is configured by providing an upward flange 42 at the tip of the extending arm portion 41. And since a pair of clamping metal fittings 13L and 13R which faced in the state which inserted fastening bolt 15 can be displaced mutually in the rotation direction centering on central axis Ax of this fastening bolt 15, this Thus, the downward hook 25a and the upward hook 25b can be made to face each other in a posture that does not interfere with the Y direction. When the sandwiching brackets 13L and 13R are held together, the arm portion 41 of the upward hook 25b The lower side of 39 is preferably passed through to face the protrusion 40. Therefore, if the clamps 13L and 13R are further tightly joined by fastening the fastening bolt 15, the arm portion 41 of the upward hook 25b is guided upward along the guide surface 41a of the protrusion 40, and downward Since it is engaged with the lower surface of the arm portion 38 of the hook 25a, there is an effect that the downward hook 25a and the upward hook 25b can be easily pivoted.

According to the fifth aspect of the present invention, the support metal fitting 2 includes a base plate portion 5 that crosses the flange 1a by bending a metal plate, and a leg plate that is suspended from both sides of the base plate portion 5. Parts 6 and 6 are configured to mount the solar cell module on the base plate part 5, and by cutting up part of the bent parts of the base plate part 5 and the leg plate part 6, Since the ground piece 10 having the tip protruding upward is provided, it is not necessary to separately provide a grounding metal, and the ground structure of the solar cell module can be provided with a simple configuration at low cost.

A nut 16 is used.

The pair of sandwiching metal fittings 13L and 13R is composed of a pair of identical metal parts 13 that are identical to each other, and the metal parts 13 are provided with a body portion 18 having an insertion hole 17 through which the fastening bolt 15 is inserted. A holding part 19 provided at the lower part of the main body part 18; a locking concave part 20 which is located at the upper part of the main body part 18 and opens in the fastening direction (Y direction in the figure) of the fastening bolt 18; The main body portion 18 includes a locking portion 21 provided on one side portion of both side portions in the X direction and a locked portion 22 provided on the other side portion.

Therefore, as shown in FIG. 2, the same component fittings 13, 13 are faced to each other, and the square head portion 14 a of the connecting bolt 14 is interposed between the locking recesses 20, 20 (in the example shown, a hexagonal head). As shown in FIG. 5, the heads 14 a of the connecting bolts 14 can be held between the locking recesses 20, 20 of both metal fittings by bringing the same metal fittings 13, 13 together. It is possible to engage the locking portion 21 and the locked portion 22 facing each other on both side portions of both metal fittings so that both metal fittings can be pivoted.

In the case of the illustrated embodiment, the same component metal fitting 13 is provided with a lateral rib 23 extending from the main body portion 18 by bending the upper edge portion of the main body portion 18 formed of a metal plate. The first vertical rib 24a and the second vertical rib 24b are provided by bending both side edges into an L shape in the protruding direction of the horizontal rib 23, and the locking recess 20 is formed by notching the horizontal rib 23. Is forming.

Preferably, the horizontal rib 23 forms a horizontal plate portion 23a and a vertical plate portion 23b by bending the upper edge portion of the main body portion 18 downward U-shaped, and the locking recess 20 is An insertion portion 20a in which the plate portion 23a is cut out in a semicircular shape and an engagement portion 20b in communication with the insertion portion 20a and in which the vertical plate portion 23b is cut out are formed. Therefore, when the pair of identical metal parts 13 and 13 are put together and the vertical plate portions 23b and 23b are brought close to each other, the rectangular head portion 14a is fitted into the engaging portions 20b and 20b. The head portion 14a is locked to both side edges of the engaging portion 20b so as not to rotate, and the neck portion of the connecting bolt 14 is inserted upward from the insertion portions 20a and 20a.

The locking portion 21 provided on one side of the both side portions of the main body 18 is constituted by a downward hook 25a, and the locked portion 22 provided on the other side is constituted by an upward hook 25b. One hook (upward hook 25b in the illustrated example) of the downward hook 25a and the upward hook 25b is disposed in the X direction, and the other hook (downward hook 25a in the illustrated example) is disposed in the Y direction. Arranged in the direction.

In the case of the illustrated configuration, the same component fitting 13 includes a lateral rib 23, a first longitudinal rib 24 a, and a second longitudinal rib 24 b, and corresponds to one side portion of both side portions of the main body portion 18 in the X direction. The X-direction hook 25b extends from the end of the horizontal rib 20, and the Y-direction hook 25a extends from the vertical rib 24a corresponding to the other side. Therefore, although it is a metal fitting of a comparatively complicated form, the same component metal fitting 13 can be manufactured by stamping and pressing one metal plate.

Then, when the pair of identical metal parts 13 and 13 are put together and the downward hook 25a and the upward hook 25b are engaged with each other, the hooks 25a and 25b are engaged with each other from above and below, so that the metal parts 13 and 13 are mutually connected. A hook 25b extending in the X direction is pivotally connected to the hook 25a extending in the X direction, and the hook 25a extending in the Y direction is pivotally pivoted about the support shaft.

Therefore, due to the meshing from above and below, the pair of identical metal parts 13 and 13 are not easily separated from each other even when the fastening bolts 15 are not inserted, and one of them is dropped from the other. The fastening bolt 15 can be easily inserted into the insertion holes 17 of the metal fittings 13 and 13 after that.

Regarding the configuration of the downward hook 25a and the upward hook 25b, in the drawing, the downward hook 25a is formed by a hook extending in the Y direction from the vertical rib 24a, and the upward hook 25b is formed by a hook extending in the X direction from the lateral rib 23. However, an opposite configuration may be adopted, and an upward hook may be extended from the vertical rib 24a in the Y direction, and a downward hook may be extended from the horizontal rib 23 in the X direction.

In the case of the illustrated configuration, the gripping portion 19 is formed by bending the lower edge portion of the main body portion 18 in the Y direction, and is further located on both sides of the gripping portion 19 so that the vertical portion A claw portion 26 protruding from the lower end of the ribs 24a and 24b in the Y direction is provided.

Therefore, in the fixing bracket 3 configured by combining the sandwiching brackets 13L and 13R made of the same component bracket 13 as described above, the connecting bolt 14 protruding upward is inserted into the insertion hole 8 of the support bracket 2 from below. As a result, it is stored between the leg plate portions 6 and 6 on the lower side of the base plate portion 5 of the support fitting 2.

Therefore, as shown in FIG. 6, the support metal fitting 2 in which the fixing metal fitting 3 is stored is installed on the roof 1 so that the two leg plate portions 6 and 6 straddle the flange 1a. By tightening the fastening bolt 15 and the fastening nut 16 through the operation windows 7 and 7, the pair of clamping fittings 13L and 13R clamp the base portion of the flange 1a by the gripping portion 19 and the claw portion 26. Thus, it is firmly fixed on the roof.

(Preferred embodiment of the pivoting structure)
As shown in FIG. 3 (A), the same part metal parts 13 constituting the sandwiching metal parts 13L and 13R are connected to the main body part 18 with respect to the distance from the central axis Ax of the fastening bolt 15 inserted through the insertion hole 17.

Therefore, when the pair of clamping fittings 13L and 13R are temporarily fixed by inserting the fastening bolts 15 through the insertion holes 17, the flange portions 39 of the downward hooks 25a facing each other face the arm portions 41 of the upward hooks 25b. Therefore, even if the clamping fittings 13L and 13R are simply pulled in the Y direction, the hooks 25a and 25b are not engaged with each other.

In the case of the illustrated embodiment, as shown in FIG. 3C, in the temporarily fixed state in which the fastening bolt 15 is inserted, the sandwiching brackets 13L and 13R are displaced in the rotation direction about the central axis Ax. It is possible to make it. That is, when one of the clamps 13L is rotated in the clockwise direction R1 shown in the drawing, the downward hook 25a of the clamp 13L moves upward and the upward hook 25b moves downward. When the other clamp 13R is rotated in the counterclockwise direction R2 shown in the drawing, similarly, the downward hook 25a of the clamp 13R moves upward and the upward hook 25b moves downward. As a result, the downward hook 25a and the upward hook 25b facing each other between the sandwiching fittings 13L and 13R are displaced in the vertical direction, so that they can be engaged with each other by moving in the Y direction.

FIG. 4 sequentially shows a method of engaging the hooks 25a and 25b. In the temporarily fixed state in which the fastening bolts 15 are inserted into the pair of sandwiching fittings 13L and 13R, the downward hook 25a and the upward hook 25b that face each other are provided with a flange portion 39 and an arm portion 41 as shown in FIG. Opposite to.

When the metal fitting is rotated around the central axis Ax as described above in this temporarily fixed state, the downward hook 25a moves upward and the upward hook 25b moves downward as shown in FIG. 4B. The flange 39 and the arm 41 are displaced up and down.

Therefore, when the metal fittings 13L and 13R are pulled toward each other by fastening the fastening bolt 15 or the like, the arm portion 41 passes below the flange portion 39 and faces the projection 40 as shown in FIG. I can. At this time, the flange portion 39 of the downward hook 25a overlaps the outer surface of the second vertical rib 24b of the other sandwiching fitting 13R.

Subsequently, when the metal fittings 13L and 13R are pulled toward each other by further fastening the fastening bolt 15, the arm portion 41 moves downward along the guide surface 40a of the protrusion 40 as shown in FIG. Is engaged with the lower surface of the arm portion 38. When pulling each other, the pair of sandwiching brackets 13L and 13R, as described above, can be displaced or rattled in the X direction with the second ribs 24b and 24b held by the downward hooks 25a and 25a. It does not occur and is preferably guided in the Y direction by tightening the fastening bolt 15.
