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 rotated or wobbled.

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

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 sandwiched above the nut, the structure further includes a support plate placed on the nut and having a through-hole through which the bolt body passes, and an inwardly facing piece. Has a shape that is inclined upright from the bent base toward the tip, and when the bolt body is clamped, the bent base contacts the upper surface of the support plate and presses the upper surface of the corrugated roof. ing.

  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 superimposing the adjacent corrugated roof on the top of the corrugated roof, and the bolt body and the nut as a fixing member that penetrates and fixes the overlapping portion of the corrugated roof. Is provided.

A mounting structure for a rooftop fixture according to a fourth aspect is formed by attaching the rooftop fixture according to any one of the first to third aspects to a corrugated roof.

  The present invention has the following effects.

That is, according to the mounting structure of the roof mounting tool according to claim 1 and the roof mounting tool according to claim 6, the inwardly facing piece has a shape that is inclined upright from the bent base portion toward the tip portion, and the bolt body Since the bent base is pressed against the top surface of the corrugated roof when sandwiched between the two, it can be prevented from rotating or wobbling with its strong pressing force, and the roof mounting fixture can be attached to the roof. On the other hand, it can be firmly and stably fixed.
Moreover, since it is the structure further provided with the support plate mounted on a nut and the bending base part of an inward flange piece contacts the upper surface of the support plate, the inward flange piece of a roof mounting tool Can press the corrugated roof via a nut or washer, and can increase the coupling force to the corrugated roof. Even if the height from the top of the top to the clamping position is high due to the structure that presses the support plate, a washer is interposed between the nut and the top of the folded plate roof. It is not particularly necessary to form a steep slope, which is particularly effective.

  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. . In addition, although the position of the inward flange piece is increased by providing the washer, it is possible to dodge the washer and clamp it to the bolt body by making the inclination of the inward flange piece steep.

  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.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. In the following, as the corrugated roof to which the on-roof fixture of the present invention is attached, an angular corrugated roof, that is, a folded-plate roof, is exemplified, but a round corrugated roof (substantially semicircular peaks and valleys) It can also be applied to roofs that are alternately continuous. Moreover, as materials for the roof, metals, synthetic resins, cement-based materials and the like can be applied.

FIG. 1 is an explanatory view showing a first embodiment (reference example) of an on-roof fixture according to the present invention, and FIG. 1 (a) is a front view showing an attachment state of the on-roof fixture to a folded plate roof. FIG. 1 and FIG. 1B are side views of the same. 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 mountain portions 31 and valley portions 32 are alternately arranged, and a plurality of folded plate roof materials are polymerized at the top portion 31a of the mountain portion 31, and the polymerization is performed. The part 30a has a stacked structure in which the bolt body 21 and the nut 22 are connected 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 two inwardly extending flanges 12 and 12 that are bent and extended so as to face each other, tighten both leg pieces 11b and 11b, and make both inwardly extending flanges 12 and 12 close to each other. The shaft 21a of the bolt body 21 is structured to be clamped to 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.

  And in this embodiment, the inward flange piece 12 extended from the leg piece 11b becomes the shape where it inclined and stood toward the front-end | tip part 12b from the bending base 12a.

  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 at an acute angle with the shaft portion 21a of the bolt body 21, but the inwardly raised piece 12 itself is inclined. Depending on the degree of the inclination, the cut-and-raised piece 12d is cut and raised. The piece 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 both inwardly facing flange pieces 12 and 12 at the lower ends of the both leg pieces 11b and 11b. Are close to each other so that the gap 15 becomes small. Then, when both the inward flange pieces 12 and 12 are close to each other, both the recesses 12c and 12c of the both end portions 12b and 12b sandwich the shaft portion 21a of the bolt body 21, and the cut and raised piece 12d is the bolt body 21. The two bite into the screw groove and 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 the leg pieces 11b and 11b are fastened with the fastening bolt 13 and the fastening nut 14 in this way, as shown in FIG. 1, the lower ends of the leg pieces 11b and 11b approach each other, and the leg pieces 11b and 11b are inclined. The state has changed from a state to a substantially vertical state, whereby both the inwardly facing pieces 12 and 12 are inclined more steeply.

  At this time, since the end of the recess 12c including the cut-and-raised piece 12d of the distal end portion 12b of the inward flange piece 12 is fixed by biting into the thread groove of the bolt body 21, the lower side of the inward flange piece 12 with respect to the shaft portion 21a. The pushing-up force from the side generates a downward repulsive force, and the repulsive force acts to press the upper surface of the top portion 31a of the folded plate roof 30 in which the bent base portion 12a of the inwardly facing piece 12 is fixed. That is, the roof mounting fixture 10 is supported and fixed at three locations by biting into the bolt body 21 of the tip 12b of the inward flange 12 and pressing against the top 31a of the bent base 12a of the inward flange 12. The

  In this way, since the upward movement is restricted by the bolt body 21, the upper surface of the top part 31a of the folded plate roof 30 is pressed, so that the inwardly facing piece 12 of the roof mounting fixture 10 has the bolt body 21 and the top part 31a. And firmly fixed to the folded-plate roof 30. Since the on-roof fixture 10 is firmly attached by pressing, the on-roof fixture 10 rotates horizontally when an external force is applied without providing a rotation-preventing piece or the like for restricting the rotation of the folded plate roof 30. Or wobbling.

  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.

FIG. 4 is an explanatory view showing a second embodiment (example) of the on-roof fixture according to the present invention, and FIG. 4 (a) is a front view showing an attached state of the on-roof fixture to the folded plate roof. FIG. 4 and FIG. 4B are side views of the same. 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.

  The roof mounting fixture 10 also has substantially the same shape and structure as that of the first embodiment, but is provided on the nut 22 and has a support plate 16 having a through hole 16a through which the bolt body 21 passes. Is included. The structure of the main body part 11 of the rooftop fixture 10, the structure of the inward flange piece 12, and the tightening structure by the leg pieces 11b are the same as those of the first embodiment, and the same reference numerals are given to the same configurations. I will omit those explanations.

  The support plate 16 directly receives the bent base portion 12a of the inward flange piece 12 when the both inward flange pieces 12 and 12 are clamped to the bolt body 21, and the main body portion 11 of the roof mounting fixture 10 The main body of the fixture comprising the flange 12, the tightening bolt 13, and the tightening nut 14 is supported. Since the nut 22 and the washer 23 are intimately sandwiched between the support plate 16 and the top portion 31a of the folded plate roof 30, the bent base portion 12a covers the upper surface of the top portion 31a of the fixed folded plate roof 30. It will be pressed indirectly.

  Therefore, the roof mounting fixture 10 can be firmly fixed to the folded plate roof 30 without rotation, wobble, etc., as in the first embodiment. In particular, since the bent base portion 12a of the inward flange 12 is configured to press the support plate 16, a washer 23 is interposed between the nut 22 and the top portion 31a of the folded plate roof 30 as in this embodiment. Even when the height from the top surface of the top portion 31a to the clamping position of the inward flange 12 is high, the inclination of the inward flange 12 does not have to be steep, which is particularly effective.

  Instead of the support plate 16, a pedestal such as a pedestal placed directly on the upper surface of the top portion 31 a may be provided, and the upper surface of the folded plate roof 30 may be pressed through the pedestal.

  Also, the folded plate roof 30 in which the washer 23 is not provided as in the first embodiment may be provided with the support plate 16, or the washer 23 is provided as in the second embodiment. Even if it is the folded-plate roof 30 of a form, it is good also as a structure which presses the top part of a folded-plate roof directly not via the support plate 16. FIG.

  Moreover, in the above 1st, 2nd embodiment, although the example which distribute | arranged the roof mounting fixture 10 to the superposition | polymerization part 30a of both adjacent roof materials was shown, it is in the top part of the mountain part in which the superposition | polymerization part is not formed. The on-roof fixture 10 may be attached.

  Furthermore, although the above 1st, 2nd embodiment showed the example which has arrange | positioned the roof fixture 10 so that both leg pieces 11b and 11b may be arranged along the direction of the peak part 31 and the trough part 32. The on-roof fixture 10 may be arranged so that both leg pieces 11b and 11b are arranged along the wave direction. In that case, especially in the case of a round corrugated roof, when the length between the tops of the waves is short and the height from the bottom surface of the valley 32 to the top of the peak 31 is low, the folding of the inwardly facing strip 12 is performed. The configuration in which the curved base portion 12 a abuts against the bottom surface of the valley portion 32 may be employed. That is, the mounting structure of the roof mounting tool may be a structure in which the bent base portion 12a of the inward facing piece 12 presses any part of the top surface of the corrugated roof.

  In addition, although it is desirable to arrange | position the roof mounting fixture 10 in the said 2 types of direction, you may distribute | arrange in any direction other than those.

  Further, the above-described roof mounting tool can be attached to a flat plate (not having a corrugated shape) roof.
