Patent No. 4505283 JP2011-149168A JP2003-343058

The support member 18 used in FIG. 6 has a simple inverted U shape that opens downward. A slot 24 and a slit 26 are formed on the upper surface to accommodate various mounting pitches.
For this reason, the section modulus of the support member 18 is reduced, and the rigidity of the support member 18 itself is lost. As a result, there is a problem that the installation location is limited. In order to increase the strength, many stoppers 22 are required, leading to an increase in cost.

The support material of FIGS. 7 and 8 is made of an extruded aluminum material, and the reduction of the section modulus can be prevented. However, there were the following problems.
First of all, there was a possibility of dropping on the roof to handle fine bolts and nuts. And it took a lot of work to install, especially from the side, it was very difficult to work.
Further, since the support material has a complicated shape by forming a plurality of grooves or through holes, it has been an expensive member.

In the case of FIG. 7, in addition to the above description, there are the following problems.
The support member 2 of FIG. 7 fits and holds the rod-shaped material 2a in the adjustment groove 21 formed on one side of the side surface. For this reason, when the external member 1 is placed, the support member 2 is not equally applied with force, and is not easily fixed firmly.
Moreover, since the position which fits and hold | maintains the rod-shaped material 2a in the adjustment groove | channel 21 is limited, it was difficult to adjust the height of the eaves-ridge direction.

In the case of FIG. 8, it takes time to position the through hole 32 of the vertical beam 31 with respect to the lower fixing bracket 26, and it takes time to insert the through bolt 29 and tighten it with a nut.
In addition, there were many small parts such as ribbon nuts 35, bolts 36, and through bolts 29, a lower fixing bracket 26 attached to each roof material, and the number of members.

The present application uses a support material having a relatively high strength even if it is a bent product, places the support material on a support material receiver, and fixes it using a support material fixing tool.
Thereby, it aims at providing the fixing structure of the support material for installation objects on a roof with low cost and high intensity | strength. Moreover, the fixing structure with good workability is provided.

The structure for fixing the support material for rooftop installation according to the present application is a structure in which the support material for installation on the roof is placed on a support material receiver, and the support material is fixed using the support material fixing tool.
The following member is used for the fixing structure of the support material for roof installations of this application.
The support member has a base portion that is placed on the support member receiver, an elevation surface portion, and a support material upper surface portion. And the opening part is formed in the support material upper surface part.
The support material holder on which the support material is placed has a support surface on which the support material is placed and a placement surface on which the support material support is placed.
The support material fixture for fixing the support material has a contact portion and a tightening portion.

  And it is the fixed structure where each member was constructed as follows. Support material receptacles are attached at predetermined intervals in the eaves-ridge direction. Therefore, the support material is bridged over the support surfaces of the plurality of support material receivers, and the contact portion of the support material fixing tool is inserted into the opening of the support material. Next, a support material is fixed using a support material fixing tool. At this time, the support structure for an installation object on the roof is characterized in that the contact portions are in contact with the left and right edges of the opening on the upper surface of the support material.

The support material of the present application has a base portion, an elevation surface portion, and a support material upper surface portion. For this reason, even if it is a comparatively simple shape and an inexpensive bending processed product, unlike FIG. 6, it is a highly rigid support material. Thereby, it can be used also in a place with a large wind load.
Further, when the support material is fixed, the corner portion of the support material is tightened by the tightening portion. And the contact part inserted from the opening part of a support material upper surface part is contact | abutted to the right-and-left edge of an opening part. Since the support material is tightened and the left and right movements of the support material are restricted by the contact portion, the support material is firmly fixed.
Furthermore, unlike the structure of FIGS. 7 and 8, it is not necessary to perform construction using fine bolts and nuts from the lateral direction. For this reason, it is a fixed structure with good workability.

First, the fixing structure of the support for a roof installation object according to the present application will be described with reference to FIGS.
FIGS. 1A and 1A are explanatory views showing an example of a fixing structure for a support for a roof-mounted object according to the present application. (A) is the state seen from the front, and (A) shows the state seen from the side.
FIG. 2 is an explanatory view showing an example of a member used in the present application.

1 and 2 show a case where the mounting bracket 4 is fixed to a horizontal roofing material (not shown), and the support member 6 is fixed to the mounting bracket 4.
The mounting bracket 4 is fixed with a fixed piece 41 and an insertion piece 42 sandwiched between horizontal roofing materials.

Next, the support material receiver 5 combined with the mounting bracket 4 will be described.
In the case of the present embodiment, the support material receiving member 5 has a substantially hat shape that opens upward. And it has the mounting surface 51 for mounting the support material holder 5 in the attachment metal fitting 4, and the receiving surfaces 52 * 52 bent up outward after raising the both sides.
The mounting surface 51 of the present embodiment is notched in order to be combined with the mounting bracket 4. Further, a bolt S <b> 1 for combining with the support material fixture 7 is attached to the mounting surface 51 upward.
The support material receiver 5 may be combined with the mounting bracket 4 in advance.

The support surfaces 52 and 52 of the support material receiver 5 are surfaces on which the support material 6 is placed.
The support material receiver 5 only needs to have a support surface 52 on which the support material 6 is placed and a placement surface 51 on which the support material receiver 5 is placed.

The support member 6 placed on the receiving surfaces 52 and 52 of the support member receiver 5 has the following shape.
In the case of the present embodiment, the base portion 63, the raised surface portions 62 and 62 raised from both sides thereof, and the upper surface portions 61 and 61 of the support material in which the upper end edges of the raised surface portions 62 and 62 are bent inward. And have.
There is a gap between the edges of the upper surface portions 61 and 61 of the support material. Therefore, the support member 6 of the present embodiment has the entire center portion in the length direction of the support member upper surface portion 61 as the opening K.
Unlike the support member 18 of FIG. 6, the support material 6 of the present embodiment is not affected by the long hole corresponding to the working width. When compared with FIG. 6, there is also an effect that positioning can be easily performed by moving the entire support member 6 in the eaves-ridge direction.
The opening K of the support member upper surface portion 61 may be an embodiment as shown in FIGS. In FIG. 3, the support material upper surface portion 61 of the mouth-shaped support material 6 is formed by notching an ellipse or a rectangle. FIG. 3 shows an example in which the shape, width, and length of the opening K of the support member 6 are not limited.

Next, the support material fixture 7 which fixes the above-mentioned support material 6 is demonstrated. As shown in FIG. 1 and FIG. 2, the support material fixture 7 of the present embodiment has an upper surface portion 71 and folded surfaces 74 and 74 formed by folding two opposite sides of the upper surface portion 71. The folding surfaces 74 and 74 have contact portions that contact the left and right edges of the opening K of the support member 6.
The other two opposite sides of the upper surface portion 71 are folded down to form tightening portions 72 and 72. In the case of the present embodiment, the fastening portions 72 and 72 are obliquely folded from the upper surface portion 71. The tightening portions 72 and 72 may be formed by being obliquely folded from the upper surface portion 71 and then suspended.
Further, the fastening portions 72 and 72 are bent to the outer side to form bottom surface portions 73 and 73, respectively. Holes for passing the bolts S <b> 1 of the support material receiver 5 are made in the bottom surface portions 73 and 73.

Furthermore, the folding surfaces 74 and 74 of the support material fixture 7 of the present embodiment will be described. In the case of this embodiment, the folding surfaces 74 and 74 are composed of a central portion 74b and both side portions 74a and 74a on both sides thereof.
In the case of the present embodiment, the central portion 74b is fitted into the opening K of the support member 6, and the lower end edges of both side portions 74a and 74a are formed on the support member upper surface portions 61 and 61.

Subsequently, a fixing structure using the members described so far will be described.
In advance, a plurality of support material receivers 5 are attached at predetermined intervals in the eaves-ridge direction. Therefore, the support material 6 is bridged on the support surfaces 52 and 52 of the plurality of support material receivers 5 adjacent in the eaves-ridge direction.

After the support material 6 is bridged in this way, the support material fixture 7 is fitted from above. At this time, the central portions 74b of the folding surfaces 74 and 74 of the support material fixture 7 are fitted into the opening K between the support material upper surface portions 61 and 61. Further, the bolts S1 and S1 protruding from the support material holder 5 are passed through the holes of the bottom surface portions 73 and 73. Then, the support material 6 is fixed by tightening with the nuts S2 and S2.
An on-roof installation such as a photovoltaic power generation panel is attached on the support member 6 thus fixed.
In this embodiment, a bolt S1, a nut S2, or the like is used as the fastening tool S. However, it is only necessary that the support material 6 can be fixed to the support surface 52 of the support material receiver 5 by using the support material fixing tool 7, and the means is not limited.

The effect of the fixing structure of the present application will be further described.
The fastening portions 72 and 72 of the support material fixture 7 of this embodiment are folded obliquely from the upper surface portion 71. Or it has the surface folded diagonally.
Then, the surface comes into contact with the corners of the support material upper surface portion 61 and the elevation surface portion 62 of the support material 6. When tightened with the tightening tool S, the support material fixing tool 7 presses the corners of the support material 6. For this reason, the support material 6 can be tightened strongly.

Further, in the case of the folded surface 74 of the present embodiment, the fore edge of the central portion 74 b comes into contact with the left and right edges of the opening K of the support member 6. Further, the lower end edges of the side portions 74a and 74a are in contact with the upper surface portions 61 and 61 of the support material.
For this reason, when the support member 6 is tightened by the tightening tool S, a repulsive force acts on the support member 6 and the support member fixing tool 7. Moreover, it is the small edge that comes into contact.
Therefore, as shown in FIG. 1A, the support member 6 is drawn with a broken line, so that the folded surfaces 74 and 74 bite into the left and right edges of the opening K, and a firm fixing structure is obtained.
Even if the base portion 63 of the support member 6 of the present embodiment has a long hole, the configuration is different from the support member 18 of FIG.

4A to 4E show other examples of the folding surface 74. FIG.
(A) is an example in which, on the upper surface portion 71 of the support material fixture 7, two opposing sides are folded to form the folded surfaces 74 and 74. The folding surfaces 74 and 74 of this embodiment are obtained by eliminating the side portions 74a and 74a from the folding surfaces 74 and 74 of FIG.
In the case of this embodiment, the small edges of the folding surfaces 74 and 74 serve as contact portions with respect to the left and right edges of the opening on the upper surface of the support material.
(B) In the upper surface portion 71 of the support material fixture 7, a cut is made from the edge, and the leading ends of the cuts are made to face each other to form an L-shaped cut. And the folding surface 74 * 74 is formed by folding down the isolate | separated location.
In the case of this embodiment, the folded surface is not the small edge of the folded surfaces 74 and 74 but the abutting portion with respect to the left and right edges of the opening on the upper surface of the support material.
In (c), on the upper surface portion 71 of the support material fixture 7, the lower surfaces 74 and 74 are formed by cutting the center portion of the upper surface portion 71 and then folding it.
Also in the case of this embodiment, the folded surface is a contact portion with respect to the left and right edges of the opening portion of the upper surface portion of the support material, not the small edge of the folded surfaces 74 and 74.
In (D), a U-shaped cut is made in the upper surface portion 71, and the surface is folded to form the folded surfaces 74 and 74. There may be only one place where the upper surface 71 is folded.
In the case of this embodiment, the small edges of the folding surfaces 74 and 74 serve as contact portions with respect to the left and right edges of the opening on the upper surface of the support material.
(E) forms constricted portions on the folding surfaces 74 and 74 as contact portions to the left and right edges of the opening of the upper surface portion of the support material.
In any of (a) to (e), any part of the folding surface 74 abuts on the left and right edges of the opening on the upper surface of the support material. When the support member 6 is tightened by using the tightening tool S, the small edge or the surface comes into contact with each other, so that it can be firmly fixed. Thereby, since the movement of the support material 6 is regulated, high strength is obtained.
As described above, the folding surface 74 may be inserted into the opening in accordance with the opening of the support member, and may form a contact portion that contacts the left and right edges.

FIGS. 5A to 5C show another embodiment of each member used in the present application.
As shown in FIG. 3A, the support material 6 in FIG. 3A shows an example in which an opening K is formed by cutting out the support material upper surface portion 61. Further, the support material receiving member 5 has an inverted U-shape and serves as a support surface 52 that also serves as a placement surface 51.
The support material receiver 5 may be formed according to the metal fitting on which the support material receiver 5 is placed as described above. Further, it is only necessary that the base 63 of the support material 6 can be received and supported by the support material receiving bracket 5.
(A) is an example in which the support member 6 has a hat shape, and the opening K is formed by cutting out the support member upper surface portion 61.
(C) is a support member 6 having the same cross-sectional shape as FIG. And the opening part K is formed by notching the support material upper surface part 61.
As described above, various methods of forming the support material upper surface portion 61 are conceivable.
In addition to the above, the abutting portion can be inserted into the opening K, and the abutting portion may be formed so as to abut against the left and right edges thereof to restrict the movement of the support member 6.

So far, the fixing structure of the support material for roof installations according to the present application has been described with the members attached to the side roofing material. However, it can also be applied to the following cases.
For example, the roofing material is a folded plate, and each member according to the present application is used for the metal fittings attached to the right and left adjacent saddles.
In that case, first, a support material receiver is combined and fixed to the mounting bracket. Next, the lateral support material is bridged between the support material receivers adjacent to the left and right. And a support material fixing tool is covered on the horizontal support material, and it fixes to a support material receiver.
The effect at this time is the same as the embodiment described so far.
