Description

  The present invention relates to an on-roof fixture and a mounting structure thereof, which are sandwiched between bolt bodies protruding from the top of a corrugated roof and mounted on the roof.

  Generally, various devices and members such as a television antenna, an air conditioner, a solar cell panel, a heat insulating sheet, etc. are disposed on the top surface of a corrugated roof such as a folded plate roof (angular corrugated roof) or a round corrugated roof. Conventionally, various on-roof fixtures for attaching these devices and members on the roof have been proposed (for example, see Patent Document 1).

  In particular, a structure in which the overlapping portions of adjacent roof materials are connected and fixed by screwing bolts and nuts at the tops of the peak portions of the corrugated roof in which the peak portions and the valley portions are alternately continuous. In this case, a roof mounting fixture having a structure in which a bolt body for connecting a roof material, which protrudes on the roof through the overlapped portion from below the roof, is sandwiched and fixed by opposing sandwich pieces is also proposed. ing.

  This on-roof fixture includes a main body portion having both leg pieces and a substantially inverted U-shaped cross section, and both inwardly facing flange pieces (both sandwich pieces) extending so as to face each other from the lower ends of the leg pieces. In addition, both the leg pieces are fastened with tightening bolts and nuts penetrating the both leg pieces in the lateral direction, and both inwardly facing hook pieces are sandwiched and attached to the bolt body. According to such an attachment structure, since the tip end portion of the inward flange piece can be bitten into the screw groove of the bolt body and fixed, there is no possibility that the on-roof fixture is easily detached.

Japanese Patent No. 3368374

  However, in this type of structure, since the nut to be screwed to the bolt body is arranged on the upper surface of the corrugated roof, the position where the bolt body is sandwiched between the inwardly facing pieces is on the shaft portion of the bolt body, Therefore, when the inward flange piece is clamped to the bolt body, the entire inward flange piece including the lower ends of both leg pieces is in a state of floating from the roof. Therefore, if a large external force is applied to the roof mounting tool, the roof mounting tool may be wobbled.

  The present invention has been proposed in view of such circumstances, and an object of the present invention is to provide an on-roof fixture and a mounting structure thereof that can be firmly attached to a corrugated roof without rotating or wobbling. There is to do.

In order to achieve the above object, a roof mounting fixture according to a first aspect of the present invention includes a main body portion having both leg pieces and formed in a substantially inverted U-shaped cross section, and bent so as to face each lower end of the both leg pieces. At least two inwardly extending flange pieces are provided, both leg pieces are tightened, both inwardly facing pieces are brought close to each other, and screwed to the bolt body protruding from the top of the corrugated roof In the roof mounting fixture structured to be clamped above the nuts, the lower end of the leg piece is configured to have a projecting piece that abuts the upper surface of the top of the corrugated roof, The leg pieces are formed by cutting and cutting, and both the leg pieces are fastened by tightening bolts and tightening nuts above the inward flange pieces formed by the cutting .

  In the on-roof fixture according to claim 2, a washer is interposed between the nut and the top of the corrugated roof.

  The on-roof fixture according to claim 3 is formed by superposing adjacent corrugated roofs on the top of the corrugated roof, and the bolt body and the nut are provided as fixing members that pass through and overlap the superposed part of the corrugated roof. ing.

  In the on-roof fixture according to claim 4, the projecting piece is formed by projecting a bent portion between the leg piece and the inward-facing collar piece downward.

The attachment structure of the on-roof attachment according to claim 5 is formed by attaching the on-roof attachment according to any one of claims 1 to 4 to the corrugated roof.

  The present invention has the following effects.

That is, according to the mounting structure of the rooftop fixture according to claim 1 and the rooftop fixture according to claim 5 , the projecting piece that contacts the top surface of the top of the corrugated roof is formed at the lower end of the leg piece. Therefore, it can be fixed to the folded plate roof not only by clamping to the bolt body, and the wobbling of the on-roof fixture can be prevented. Since the lower end portion of the leg piece is in contact with the top of the folded plate roof, horizontal rotation of the on-roof fixture is also difficult to occur. Further, if the projecting piece is constituted by a part of the leg piece or the inwardly facing piece, it is not necessary to add other members, and the attachment to the folded plate roof can be performed smoothly.
Further, since the leg pieces are cut and cut to form the inwardly facing pieces and the protruding pieces, a stable on-roof fixture can be easily manufactured with respect to the folded plate roof. In addition, by adjusting the cut and cut dimensions, the inward flange pieces and the projecting pieces can be formed in various shapes and dimensions suitable for the shape of the folded plate roof to be attached.

  Since the washer is interposed between the nut and the top of the corrugated roof, the roof mounting tool according to claim 2 can be waterproofed from the through hole of the bolt body by adding a waterproof packing or the like to the washer. . Also, by providing the washer, the clamping position of the inward flange piece is increased, but since the projecting piece that contacts the top of the corrugated roof is provided at the lower end part of the leg piece, the on-roof fixture is replaced with the washer. It can be clamped to the bolt body.

  The on-roof fixture according to claim 3 is configured to be sandwiched between bolt bodies for penetrating and fixing the overlapping portion of the corrugated roof. In other words, the bolt body for connecting the overlapping parts is also used for mounting the roof mounting fixture, so there is no need to newly use a bolt body for mounting the roof mounting fixture on the corrugated roof. The number of parts for can be reduced.

Fig.1 (a) is the front view which showed the attachment state to the folded plate roof of a roof mounting tool, FIG.1 (b) is the same side view. 2A is an exploded perspective view of the on-roof fixture shown in FIG. 1, and FIG. 2B is an enlarged plan view of a portion X in FIG. 3 (a) and 3 (b) are front views showing a construction state of the on-roof fixture.

  The folded plate roof 30 used in the present embodiment is a roof in which the mountain portions 31 and the valley portions 32 are alternately continued, and a plurality of folded plate roof materials are superposed on the top portion 31a of the mountain portion 31 at the side edge. In addition, the overlapping portion 30a is connected to the bolt body 21 and the nut 22 by screwing. Further, a waterproof packing (not shown) is attached between the nut 22 and the top portion 31a in order to prevent water from entering from the bolt hole 30b.

  On the other hand, the on-roof fixture 10 is made of a metal plate or a hard resin plate, and is attached and fixed to the above-described bolt body 21 for connecting the overlapping portions protruding upward from the top portion 31a of the folded plate roof 30. It has become.

  Specifically, the on-roof fixture 10 includes a main body 11 having a substantially inverted U-shaped cross section including an upper plate 11a and both leg pieces 11b and 11b extending downward from both ends, and both leg pieces 11b and 11b. At least both inwardly extending flanges 12 and 12 which are bent and extended so as to face both lower end portions 11bb and 11bb, and by tightening both leg pieces 11b and 11b, It is configured to be close to each other and clamped to the shaft portion 21 a of the bolt body 21 at a position above the nut 22 screwed to the bolt body 21. The leg pieces 11b, 11b are tightened by screwing a tightening bolt 13 and a tightening nut 14 that are passed through shaft holes 11ba, 11ba provided in the opposing leg pieces 11b, 11b.

  In the present embodiment, a projecting piece 17 is formed on the lower end portion 11bb of the leg piece 11b. The projecting piece 17 is formed by projecting the bent part 16 between the leg piece 11b and the inward flange piece 12 downward. When 10 is attached to the folded roof 30, the projecting piece 17 is in contact with the upper surface of the top 31 a of the corrugated roof 30. That is, in the present embodiment, as shown in FIG. 1 and the like, the bent base portion 12a of the inward flange piece 12 and the lower end portion 11bb of the leg piece 11b are overlapped to form the protruding piece 17. Further, the inward flange 12 is curved or bent as a whole, and the upper plate 11a extends from the bent portion 16 to the middle of the bent base portion 12a and from the middle to the edge of the tip. And a front end portion 12b formed substantially parallel to (see FIG. 3). Of course, the shape of the inward flange 12 is not limited to that shown in the figure, and may be any shape as long as it can be clamped to the bolt body 21 at least.

  Further, as shown in the enlarged plan view of FIG. 2 (b), the outer peripheral surface of the bolt body 21 protruding from the top portion 31 a of the folded plate roof 30 is provided at the approximate center of the edge of the tip 12 b of the inwardly facing piece 12. A recess 12c that can be fitted is formed, and a cut-and-raised piece 12d that is inclined upward is formed at the center of the recess 12c. The cut-and-raised piece 12d is fitted to the shaft portion 21a of the bolt body 21 at an acute angle, but if the inward flange piece 12 itself is inclined to some extent when sandwiched, the inclination Depending on the degree, the cut and raised pieces 12d may not be formed. Furthermore, a rib 12e for increasing the strength of the inward flange 12 is formed on the inward flange 12.

  The roof fixture 10 configured as described above is used by being attached to the folded plate roof 30 in the following manner.

  First, after passing the shaft portion 13a of the tightening bolt 13 from one of the shaft holes 11ba of the both leg pieces 11b, 11b of the roof mounting fixture 10, the tightening nut 14 is lightly tightened from the tip side of the tightening bolt 13. In the temporarily fixed state, the roof mounting fixture 10 is inserted into the gap 15 between the leg pieces 11b and 11b from above the bolt body 21 protruding to the folded plate roof 30, and the folded plate roof It mounts on the upper surface of the top part 31a of 30 (refer Fig.3 (a), (b)).

  Next, when the tightening bolt 13 and the tightening nut 14 that have been temporarily fixed are tightened, both the leg pieces 11b and 11b are brought close to each other by the tightening force, and the gap 15 is also reduced in both the inwardly facing flange pieces 12 and 12. Close to each other. And since both inward flanges 12 and 12 adjoin, both the recessed parts 12c and 12c of both the front-end | tip parts 12b and 12b pinch | interpose the axial part 21a of the bolt body 21, and the cut-and-raised piece 12d is the bolt body 21. The two are firmly connected and fixed (see FIG. 1).

  Various devices and members (not shown) can be attached on the main body 11 of the rooftop fixture 10 attached to the folded plate roof 30 in this manner.

  When both the leg pieces 11b and 11b are tightened with the tightening bolt 13 and the tightening nut 14 in this way, the bent portions 16 and 16 of the both leg pieces 11b and 11b approach each other as shown in FIG. 11b changes from an inclined state to a substantially vertical state, and the tip portions 12b, 12b of both inwardly facing flange pieces 12, 12 are in a state where they are slightly inclined with respect to the bolt body 21.

  In this state, both the leg pieces 11b and 11b are in a substantially vertical state with respect to the top portion 31a, so that the projecting piece 17 is also substantially in the same vertical state and is in a stable state, and is bent at the lower end of the projecting piece 17. The part 16 abuts on the upper surface of the top part 31a so as to slightly press the top part 31a.

  Thus, since the protrusion 17 is contacting the upper surface of the top part 31a of the folded-plate roof 30, the roof fixture 10 is not only attached to the bolt body 21 with respect to the folded-plate roof 30. The wobbling of the on-roof fixture 10 can be reliably prevented. Moreover, since the lower end part 11bb of the leg piece 11b is in contact with the top part 31a of the folded-plate roof 30, the horizontal rotation of the on-roof fixture 10 hardly occurs. Further, since the projecting piece 17 is constituted by a part of the leg piece 11b and the inward-facing collar piece 12, it is not necessary to add other members, and the attachment can be performed smoothly.

  Further, in the present embodiment, since the bent portion 16 between the leg piece 11b and the inward flange piece 12 protrudes downward to form the protruding piece 17, the structure can be simplified, and the on-roof fixture 10 can be manufactured easily. Furthermore, if the projecting piece 17 is formed by superimposing the leg pieces 11b and the inward flange piece 12 as in this example, the structure of the on-roof fixture 10 can be made robust.

  Moreover, in this embodiment, since the bolt body 21 for attaching the roof mounting tool 10 to the folded plate roof 30 is also used for roof material connection, the number of parts for attachment may be reduced. it can.

4 and 5 are explanatory views showing a second embodiment (example) of the on-roof fixture according to the present invention. Fig.4 (a) is the front view which showed the attachment state to the folded plate roof of a roof mounting tool, FIG.4 (b) is the same side view. 5 is an exploded perspective view of the on-roof fixture shown in FIG. In addition, in this embodiment, the construction state figure of a roof fixture is abbreviate | omitted.

  The folded plate roof 30 used in the present embodiment has a stacked structure in which the overlapping portion 30a of the roof material is connected by screwing the bolt body 21 and the nut 22 as in the first embodiment. Between the nut 22 and the top portion 31a of the folded plate roof 30, a substantially conical washer 23 with a waterproof packing is attached to prevent water from entering from the bolt hole 30b. In addition, you may use what integrated the nut 22 and the washer 23. FIG.

  On the other hand, the on-roof fixture 10 is formed by cutting and cutting the plate body for forming the leg pieces 11b with the inward flange pieces 12 and the projecting pieces 17. In this example of the on-roof fixture 10, two incisions parallel to the side of the leg piece 11b are made upward from the lower end of the plate body, and the central piece formed by the incision is cut and raised inwardly. On the other hand, a projecting piece 17 composed of two side pieces formed by cutting is formed on the lower end portion 11bb of the leg piece 11b. Further, the projecting piece 17 is formed with a foot portion 17a whose lower end is bent outward and in surface contact with the upper surface of the top portion 31a. Since the foot portion 17a is formed by the remainder of the leg piece 11b, it does not have to be formed depending on the relationship with the dimension of the inward heel piece 12.

  In addition, a recess 12c and a cut-and-raised piece 12d are formed at the edge of the distal end portion 12b of the inward flange piece 12. In the present embodiment, the same structures as those of the first embodiment are denoted by the same reference numerals and description thereof is omitted (the same applies to FIG. 6 described later). Moreover, the code | symbol 16 in FIG.4 and FIG.5 is a bending part between the leg piece 11b and the inward heel piece 12. FIG.

  Thus, in the present embodiment, the plate body for forming the leg piece 11b is cut and cut to form the inward flange piece 12 and the protruding piece 17, so that it is stable with respect to the folded plate roof 30. The on-roof fixture 10 can be easily manufactured. Further, by adjusting the cut and cut dimensions, the inward flange piece 12 and the projecting piece 17 can be formed in various shapes and dimensions that match the shape of the folded plate roof 30 to be attached. In particular, since the height position of the inward flange 12 can be increased by adjusting the incision dimension, the position of clamping to the bolt body 21 by the washer 23 and the nut 22 as in the folded plate roof 30 of the present embodiment. When it becomes high, it can be used as an effective roof fixture. Moreover, by forming the foot portion 17a at the tip of the projecting piece 17, the roof mounting fixture 10 can be more stably attached to the top portion 31a.

  FIG. 6 is an explanatory view showing two other examples of the on-roof fixture of the second embodiment, and FIG. 6A is a perspective view (tightening) showing a state before the on-roof fixture of the first example is attached. Bolts and nuts are not shown), and FIG. 6 (b) is a side view showing a mounting state of the rooftop fixture of the second example.

  The roof top fixture 10 of the 1st example shown to Fig.6 (a) cuts the board | plate body in which the inward flange piece 12 and the protrusion piece 17 form the leg piece 11b similarly to the thing of FIG. The protruding piece 17 is formed at the lower end portion 11bb of the leg piece 11b. In addition, about the structure similar to FIG. 4, the same code | symbol is attached | subjected and the description is omitted. Further, ribs 12e are formed on the inward flange piece 12.

  This first example can also be formed by cutting the inward flange piece 12 and the projecting piece 17 and cutting, so the same effect as that of FIG. 4 can be obtained.

  Moreover, the roof mounting fixture 10 of the 2nd example shown in FIG.6 (b) shows the modification of the roof mounting fixture shown in FIG. This on-roof fixture 10 is formed by cutting a plate body for forming a leg piece 11b and forming an inward flange piece 12 and a protruding piece 17 by cutting, and the protruding piece 17 is a lower end portion 11bb of the leg piece 11b. Is formed. A pair of fixture detent pieces 18 that sandwich the top portion 31a is formed below the projecting piece 17. This fixture detent piece 18 can be formed by cutting out the lower end of the projecting piece 17, thereby restricting horizontal rotation of the roof fixture 10.

  In the two types of on-roof fixtures shown in the first and second embodiments, the first embodiment is attached to the folded plate roof 30 in which the washer 23 is not provided. Although the thing of this embodiment is attached with respect to the folded-plate roof 30 of the form which provided the washer 23, the folded-plate roof which is an attachment object may be any form for any on-roof fixture. .

  In any of the embodiments, the projecting piece 17 is formed integrally with the leg piece 11b and the inwardly facing flange piece 12, but a separate projecting piece is added to the lower end portion 11bb of the leg piece 11. Also good.

  Moreover, in the above 1st, 2nd embodiment, although the example which distribute | arranged the roof mounting fixture 10 to the overlapping part 30a of both adjacent roof materials was shown, the top part of the peak part 31 in which the overlapping part is not formed You may attach the roof mounting fixture 10 to 31a.
