  Drawing 1 is an explanatory view of a 1st embodiment of a roof fixture according to the present invention, and is an exploded perspective view showing a state before attaching a roof fixture to a corrugated roof. FIG. 2 is a development view of the sandwiching piece of the on-roof fixture. FIG. 3 is a partially broken perspective view showing a state after the roof fixture is attached to the corrugated roof. 4 (a), 4 (b) and 5 (c) are partial cross-sectional front views illustrating the construction procedure of the roof mounting fixture. FIG. 6 is a diagram for explaining a mounting state of the on-roof fixture on the corrugated roof.

  Examples of the corrugated roof to which the on-roof fixture A is attached include the folded plate roof Y (angular corrugated roof) and the round corrugated roof shown as examples. Moreover, as materials for the roof, metals, synthetic resins, cement-based materials and the like can be applied.

  The folded plate roof Y shown as an example is a roof in which mountain portions Y1 and valley portions Y2 are alternately continuous, and a plurality of folded plate roof materials are polymerized at the top portion Y1a of the mountain portion Y1 on the side edge, It has a stacked connection structure in which the bolt body B and the nut C1 are connected to each other at the overlapping portion.

  In the illustrated example, the nut C1 constitutes a washer portion C together with a washer C2 below the nut C1. The washer C2 covers the waterproof packing C3 for preventing water from entering from the bolt hole. Note that the washer portion C does not include the washer C2 as shown in the figure, and may be configured only by the nut C1 that is screwed.

  Further, on the back side of the folded plate roof Y, a support fitting Y3 for bolting, which is substantially the same shape as the folded plate roof Y in a front view, is attached. The folded plate roof Y is supported by the support fitting Y3. In addition, the attachment position of the bolt body B for attaching the roof mounting fixture A is not limited to the overlapped portion of the adjacent folded plate roof material, and even if the bolt body B is attached to the other top portion Y1a using the support fitting Y3. Good.

  The on-roof fixture A is made of a metal plate or a hard resin plate, and has a structure in which it is attached and fixed by being sandwiched by the bolt body B protruding upward from the top Y1a of the folded plate roof Y.

  Specifically, the roof mounting fixture A has a pedestal portion 11, a pair of leg pieces 12, 12 extending downward from both ends thereof, and tips of the leg pieces 12, 12 so that the tips thereof face each other. It is comprised by the substantially portal-shaped clamping tool 1 integrally formed with the clamping pieces 13 and 13 bent at the 2nd, The both leg pieces 12 and 12 are clamped, and both clamping pieces 13 and 13 are comprised. The front ends of the bolts are close to each other and are clamped to the bolt body B.

  The both leg pieces 12 and 12 are tightened by screwing a tightening bolt 25 and a tightening nut 26 that are passed through shaft holes 12 a and 12 a provided in the opposing leg pieces 12 and 12.

  In the on-roof fixture A shown in the figure, reinforcing ribs 11x and 12x are formed on the pedestal portion 11 and both leg pieces 12 and 12, respectively.

  The sandwiching piece 13 has a roof mounting portion 13a that comes into contact with the top surface of the top portion Y1a when the roof mounting fixture A is attached to the top portion Y1a of the folded plate roof Y, and is bent upward at the tip portion thereof. A rising portion 13c is formed, and a bolt locking groove portion 13b formed of a half cylinder that is locked to the male screw portion B1 of the bolt body B is formed at the center of the rising portion 13c.

  At both ends of the rising portion 13c, tightening protruding pieces 14 are formed that protrude outward in the penetration direction (width direction of the leg pieces 12) of the central opening of the roof mounting fixture A. Bolt insertion holes 14 a are formed in the tightening protrusions 14 so that the opposing tightening protrusions 14 and 14 can be fastened and fixed with bolts 15 and nuts 16. Instead of the bolt 15 and the nut 16, a fixing tool such as a drill screw may be used, or it may be fixed by caulking. When a drill screw is used, the bolt protrusion 14a may not be provided in the tightening protrusion piece 14.

  Moreover, as shown in the development view of the sandwiching piece 13 in FIG. 2, the roof mounting portion 13a is formed with a large opening at the center, and when the sandwiching piece 13 is formed by bending the opening, When the on-roof fixture A is installed on the top portion Y1a, a washer portion accommodating space 13aa is formed which accommodates (avoids) the washer portion C.

  The washer portion accommodating space 13aa may be a space that can accommodate the size of the washer C2 in a plan view and can accommodate the upper end of the nut C1 in the height direction.

  Further, the bolt locking groove portion 13b is formed of a half cylinder with an internal thread portion 13ba formed on the inner side, and the bolt body B is held by the both bolt locking groove portions 13b and 13b by tightening the leg piece 12, whereby the male screw Locked with the part B1. In this way, the male screw portion B1 and the bolt locking groove portion 13b are formed so that the screw thread and the screw groove mesh with each other to form a strong clamping relationship, whereby the roof mounting tool A is fixed to the bolt body B. The

  Moreover, as shown in FIG. 3, the roof mounting fixture A is fixed so that it may be mounted on the upper surface of the top part Y1a. That is, when the on-roof fixture A is installed, the on-roof placement portion 13a of the sandwiching piece 13 comes into contact with the upper surface of the top portion Y1a.

  Therefore, according to this roof mounting fixture A, the bolt locking groove 13b can be securely locked and clamped to the bolt body B protruding from the top Y1a of the folded plate roof Y, and two sets of tightening protruding pieces By fastening 14 and 14 together, it can prevent almost certainly that the space | interval between the clamping pieces 13 and 13 clamped firmly is opened. In particular, the tightening protruding piece 14 shown in the present embodiment protrudes outward, so that it is easy to perform bolting work and does not become a burden of construction.

  In this way, the bolt body B is locked to the male threaded portion B1 by the bolt locking groove 13b, the clamp body 13 is clamped to the bolt body B, and the clamping protrusions 14 and 14 are fastened to each other. With the cooperation, it is possible to almost reliably prevent the roof mounting fixture A from coming out of the bolt body B and wobbling.

  Furthermore, since it is the structure which the roof mounting part 13a contacts the top part Y1a when it attaches to the corrugated roof Y, the fixation stabilization to the bolt body B of the roof mounting tool A can be supplemented.

  Moreover, as shown in FIG. 1, even when the diameter of the washer C2 is large and a wide space cannot be obtained on both sides in the width direction of the top portion Y1a, the roof mounting portion 13a in which the washer portion accommodating space 13aa is formed is sandwiched. Since it is formed on the piece 13, even when the leg pieces 12, 12 are arranged side by side in the width direction of the top portion Y 1 a as shown in the figure, the clamping piece 13 is clamped without touching the washer C. The piece 13 can be stably brought into contact with and placed on the top surface of the top Y1a.

  FIG. 6 is a schematic plan view showing the mounting state of the roof mounting tool A on the folded plate roof Y. The roof mounting portions 13a and 13a of the sandwiched pieces 13 and 13 are cross-hatched. As shown, it is in surface contact with the upper surface of the top Y1a without contacting the washer C. As shown in FIG. 5, the roof mounting portion 13a is in contact with the top surface of the top portion Y1a at the circulating portion of the washer portion C, so that stable installation can be expected.

  The on-roof fixture A of the present invention configured as described above is used by being attached to the folded plate roof Y in the following manner.

  First, the shaft portion 25a of the tightening bolt 25 is penetrated from one of the shaft holes 12a, 12a of the both leg pieces 12, 12, and the tightening nut 26 is lightly tightened from the distal end side of the tightening bolt 25 to be in a temporarily fixed state. Thus, the bolt body B is inserted from above the bolt body B standing on the folded plate roof Y through the gap S between the bolt locking groove portions 13b and 13b of the sandwiching pieces 13 and 13 (FIG. 4A). ) And (b)).

  Next, when the tightening bolt 25 and the tightening nut 26 that have been temporarily fixed are tightened, both the leg pieces 12 and 12 are brought close to each other by the tightening force, and the bolt locking groove portions 13b of the both sandwiching pieces 13 and 13 are connected. 13b are also close to each other, both the half cylinders sandwich the male screw part B1 of the bolt body B, and the bolt locking groove parts 13b and 13b are locked to the screw grooves on the outer peripheral surface of the male screw part B1 of the bolt body B. The bolt body B is clamped (by forming a screwing relationship) (see FIGS. 4B and 5C).

  Finally, the tightening protrusions 14 and 14 that are in a face-to-face contact or in close proximity are fastened and fixed by screwing bolts 15 and nuts 16 (see FIG. 3).

  Various devices and members (not shown) can be attached above the pedestal portion 11 of the on-roof fixture A attached to the folded plate roof Y in this way (see FIG. 5C).

  According to the on-roof fixture A of the present embodiment, the sandwiching tool 1 has both leg pieces 12 and 12 formed by bending the sandwiching pieces 13 and 13 at the lower end and the leg pieces 12 and 12 at both ends. Since it is integrally formed including the pedestal 11, the clamping tool 1 can be constructed in a sturdy and simple shape.

  Further, the pair of leg pieces 12 and 12 are tightened to bring the pair of sandwiching pieces 13 and 13 close to each other. Therefore, only a fastening bolt 25 or the like for fastening the pair of leg pieces 12 and 12 is provided. The tight structure can be realized with this, so the structure can be simplified.

  In order to achieve strong clamping, the bolt locking groove portion 13b is formed of a half cylinder and the bolt locking groove portions 13b and 13b are configured to wrap the bolt body B. Although it is desirable, the bolt locking groove 13b does not have to be formed in the half cylinder as long as it can be locked to the male threaded portion B1 of the bolt body B, and a part of the outer periphery of the male threaded portion B1 of the bolt body B is locked. It may be a thing.

  Next, a second embodiment will be described.

  FIG. 7 is an explanatory diagram of the second embodiment of the rooftop fixture according to the present invention, and is a perspective view showing a state before the rooftop fixture is attached to the corrugated roof. FIG. 8 is an exploded perspective view of a sandwiching tool used for a roof mounting tool. 9 (a), 9 (b), 10 (c), and 10 (d) are partial cross-sectional front views showing the construction procedure of the on-roof fixture shown in FIG.

  In addition, in this embodiment, illustration is abbreviate | omitted about the perspective view after the attachment to the corrugated roof of the mounting tool A on a roof. In addition, a perspective view showing a mounting state of the roof mounting fixture A is substantially the same as that of the first embodiment, and hence illustration is omitted.

  As the corrugated roof to which this on-roof fixture A is attached, the folded plate roof Y (angular corrugated roof) and the round corrugated roof shown as examples are mentioned as in the first embodiment. Moreover, as materials for the roof, metals, synthetic resins, cement-based materials and the like can be applied.

  Further, the folded plate roof Y, which is the attachment target of the on-roof fixture A, is the same as the folded plate roof Y shown in the first embodiment, and the structure thereof is denoted by the same reference numerals and description thereof is omitted. To do.

  This on-roof mounting tool A constitutes a sandwiching tool 1 'by connecting a pair of sandwiching members 10, 10 so as to be openable and closable, and forms a pair of opposing sandwiches that serve as the action point of the sandwiching tool 1'. This is a fixture having a structure in which the pieces 13 and 13 are fixed close to each other and are clamped to the bolt body B protruding from the top Y1a of the folded roof Y.

  First, the clamping piece 13 that bears the clamping of the bolt body B among the components of the clamping member 10 will be described.

  Like the first embodiment, this sandwiching piece 13 has a roof mounting portion 13a that comes into contact with the top surface of the top Y1a when the roof mounting fixture A is attached to the top Y1a of the folded roof Y. A rising portion 13c bent upward is formed at the tip portion, and a bolt locking groove portion 13b made of a half cylinder that is locked to the male threaded portion B1 of the bolt body B is formed at the center of the rising portion 13c. Yes.

  At both ends of the rising portion 13c, as in the first embodiment, a tightening protruding piece 14 is formed that protrudes outward in the penetration direction (width direction of the leg piece 12) of the central opening of the roof mounting fixture A. ing. Bolt insertion holes 14 a are formed in the tightening protrusions 14 so that the opposing tightening protrusions 14 and 14 can be fastened and fixed with bolts 15 and nuts 16. In addition, you may fix with a drill screw or caulking.

  Moreover, the center part of the roof mounting part 13a is opened, and a washer part accommodating space 13aa for accommodating the washer part C when the roof mounting tool A is installed on the top part Y1a is formed by the opening. The washer portion accommodating space 13aa may be of a size that can be accommodated by the washer portion C as in the first embodiment.

  Note that the bolt locking groove 13b is also composed of a half cylinder with an internal thread 13ba formed on the inner side, as in the first embodiment, but is not limited thereto.

  Thus, according to this on-roof fixture A, the bolt locking groove 13b can be firmly clamped to the bolt body B protruding from the top Y1a of the folded plate roof Y, and two sets of tightening protruding pieces 14 can be secured. , 14 can be securely fixed to each other to prevent the tightly sandwiched sandwiching pieces 13, 13 from being opened by an external force.

  In this way, the bolt body B is locked to the male threaded portion B1 by the bolt locking groove 13b, the clamp body 13 is clamped to the bolt body B, and the clamping protrusions 14 and 14 are clamped together. By the cooperation with the fixing, it is possible to almost certainly prevent the roof fixture A from coming off from the bolt body B or wobbling.

  Furthermore, since the roof mounting portion 13a is in contact with the top Y1a, the stabilization of fixing the roof mounting tool A to the bolt body B can be complemented.

  Moreover, as shown in FIG. 7, even when the diameter of the washer C2 is large and a wide space cannot be obtained on both sides in the width direction of the top portion Y1a, the on-roof mounting portion 13a in which the washer portion accommodating space 13aa is formed is sandwiched. Since it is formed on the piece 13, even when the leg pieces 12 and 12 are arranged in the width direction of the top portion Y1a as shown in the figure, the clamping piece 13 does not touch the washer C, and the clamping is performed. The piece 13 can be stably brought into contact with the upper surface of the top Y1a.

  Next, the overall structure of the sandwiching tool 1 ′ will be described.

  Each of the pair of sandwiching members 10 and 10 constituting the sandwiching tool 1 ′ has a bolt through hole 11 e formed at the center and a cut groove 11 d extending from the bolt through hole 11 e to one side edge. A plate 11A, leg pieces 12 and 12 extending downward from the base end of the upper plate 11A, and sandwiching pieces 13 and 13 extending from the lower ends of the leg pieces 12 and 12 in substantially the same direction as the upper plate 11A; It is made up of.

  The sandwiching tool 1 ′ is arranged such that the top ends of the top plates 11 </ b> A are located below the base end of the top plate 11 </ b> A of the counterpart, with the top plates 11 </ b> A of the two sandwich members 10, 10 facing each other. In this manner, the cut grooves 11d of the upper plate 11A are inserted into each other so that the upper plates 11A and 11A are swingably engaged with each other so that the bolt through-holes 11e are aligned with each other and sandwiched between the aligned bolt through-holes 11e. The bolt locking groove portions 13b and 13b provided at the tips of the sandwiching pieces 13 and 13 are brought close to each other by passing the fastener fastening bolt 21 and screwing the fastening nut 22.

  Here, as shown in the figure, a rounded round head bolt may be used as the clamping tool clamping bolt 21. As the clamping nut 22, a nut 22a rotates on the top surface of a hat-shaped washer 22b. A nut with a washer attached freely may be used. The bolt stop 23 is made of synthetic resin or the like, and a plurality of cuts 23b are formed on the periphery of the hole 23a.

  To summarize the above structure, the two sandwiching members 10 and 10 are connected to each other in a crossing manner by a cut groove 11d formed in the upper plate 11A, and the sandwiching member tightening bolt 21 and the tightening nut 22 2 By tightening the two upper plates 11A, 11A, the tips of the upper plates 11A, 11A, which are the force points, are expanded with the cut groove 11d as a fulcrum, and the upper plates 11A, 11A in the intersecting state are brought closer to a flat plate shape, As a result, the deformed scissors structure is formed so that the sandwiching pieces 13 and 13 which are the action points are brought close to each other.

  More specifically, as shown in FIG. 8, the upper plate 11A includes a flat base end portion 11a, a step portion 11c formed on the front end side of the base end portion 11a, and a step portion 11c. Furthermore, a distal end portion 11b formed on the distal end side and located at a position lower than the base end portion 11a by about one sheet thickness is provided. An elongated hole extending across the base end portion 11a and the distal end portion 11b around the stepped portion 11c is provided substantially at the center of the upper plate 11A, and this elongated hole constitutes the bolt through hole 11e. Further, a pressing claw 11f cut and raised downward is formed on the end portion side of the long hole at the distal end portion 11b side. The cut groove 11d communicating with the bolt through hole 11e is formed along the step portion 11c. In addition, as for the upper board 11A, it is desirable for the whole to become a loose front inclination shape.

  As described above, the stepped portion 11c is formed along the bolt through hole 11e and the cut groove 11d provided at the center of the upper plate 11A, so that the cross-over polymerization occurs when the tip portion 11b of the upper plate 11A is opened. The two upper plates 11A are substantially flat, and the gap between the base end portion 11a of the upper plate 11A and the distal end portion 11b of the upper plate 11A of the counterpart sandwiching member 10 becomes smaller and may be wobbled. No more stable shape. The upper plates 11A and 11A overlapped in this way constitute a pedestal 11 for installing various devices and members.

  According to such an on-roof fixture A, the sandwiching tool 1 ′ is composed of two sandwiching members 10 and 10, and they are connected to each other so as to be openable and closable. When the clamping nut 22 is in a loose state, the two clamping members 10 and 10 are also in a loose state. Therefore, in order to fix both the sandwiching pieces 13 and 13 in the closed state, it is only necessary to fasten the upper nuts 11A and 11A by tightening the fastening nut 22, and the workability is good.

  In addition, since the two clamping members 10 and 10 are sandwiched, there is a possibility that the tips of the clamping pieces 13 may be displaced from each other. However, the fastening protruding pieces 14 and 14 are fixed to each other with bolts 15 and nuts 16 and the like. Since the structure is fixed with a tool, the occurrence of such a shift can be prevented.

  The on-roof fixture A of the present invention configured as described above is used by being attached to the folded plate roof Y in the following manner.

  First, the roof mounting fixture A is in a state where both the sandwiching pieces 13 and 13 of the sandwiching tool 1 ′ are sufficiently opened, that is, the screwing of the sandwiching tool tightening bolt 21 and the tightening nut 22 is loosened. The pinching members 10 and 10 are connected to the fulcrum so that they can be opened and closed, and the bolt body B is fitted from above the bolt body B standing on the folded plate roof Y through the gap S between the bolt locking groove portions 13b and 13b. Insert (see FIG. 9A).

  Next, when the clamping tool clamping bolt 21 and the clamping nut 22 that have been temporarily fixed are tightened, the upper plates 11A and 11A that are overlapped in a swinging and loosened state are flattened. At the same time, the sandwiching pieces 13 and 13 extending from the lower ends of the leg pieces 12 and 12 are also close to each other, and both the half-cylinders sandwich the male threaded portion B1 of the bolt body B, and the bolt locking groove portion 13b. 13b are engaged with the thread grooves on the outer peripheral surface of the male threaded portion B1 of the bolt body B to clamp the bolt body B (see FIGS. 9B and 10C).

  Finally, the tightening protrusions 14 and 14 that are brought into contact with each other or close to each other are fastened by screwing the bolts 15 and nuts 16 together.

  In addition, since the on-roof fixture A shown in the present embodiment constitutes the sandwiching tool 1 ′ by the pair of sandwiching members 10, 10, the tightening operation by the sandwiching tool tightening bolt 21 and the tightening nut 22 is performed. Therefore, in a state before the bolt locking groove 13b is locked to the bolt body B, the tips of the sandwiching pieces 13 and 13 may be displaced from each other.

  If there is such a deviation, the male threaded portion B1 of the bolt body B may not fit well in the bolt locking groove portion 13b. To prevent this, the tips of the sandwiched pieces 13 and 13 are connected to each other. At a stage of approaching to some extent, the tightening protrusions 14 and 14 may be temporarily fixed with bolts 15 and nuts 16 so that the locking to the bolt body B can be induced.

  Various devices and members E can be attached above the pedestal portion 11 of the rooftop fixture A attached to the folded plate roof Y in this way (see FIG. 10D).

  Next, another example of the third embodiment of the on-roof fixture according to the present invention will be described.

  FIG. 11 is an explanatory view of a third embodiment of the roof mounting tool according to the present invention, FIG. 11 (a) is an exploded perspective view of a clamping tool used for the roof mounting tool, and FIG. It is the front view which showed the construction state of the fixture on a roof.

  This on-roof fixture A comprises a pair of clamping members 10 and 10 that are connected to each other by clamping tool clamping bolts 21 and clamping nuts 22 so as to be freely opened and closed to constitute a clamping tool 1 '. The pair of sandwiching pieces 13 and 13 facing each other by screwing of the bolt 21 and the tightening nut 22 are fixed close to each other, and the folded plate roof Y is secured at the bolt locking grooves 13b and 13b of the sandwiching pieces 13 and 13. The bolt body B is protruded from the top portion Y1a of the bolt body B so as to be engaged and clamped.

  The clamping piece 13 further has a fastening protrusion piece 14 similar to that of the first embodiment. Therefore, also with respect to the roof mounting tool A of the present embodiment, the bolt body B is locked to the male threaded portion B1 by the bolt locking groove 13b, the clamping piece 13 is clamped to the bolt body B, and tightened. With the cooperation with the fastening and fixing of the protruding pieces 14, 14, it is possible to almost reliably prevent the roof mounting fixture A from coming out of the bolt body B and wobbling.

  Furthermore, since it is the structure which the roof mounting part 13a contacts the top part Y1a when it attaches to the corrugated roof Y, the fixation stabilization to the bolt body B of the roof mounting tool A can be supplemented.

  Each of the pair of sandwiching members 10 and 10 constituting the sandwiching tool 1 ′ has an upper plate 11 </ b> A having a bolt through hole 11 e at the center, and a leg piece that is bent from the base end of the upper plate 11 </ b> A and extends downward. 12 and a sandwiching piece 13 extending from the lower end of the leg piece 12 in substantially the same direction as the upper plate 11A. The sandwiching member 10 is formed with a rib 18 that rises upward at the center position from the end of the upper plate 11A to the lower end of the leg piece 12. The widths of the ribs 18 of the upper clamping member 10 are larger than the ribs 18 of the lower clamping member 10 so that the upper plates 11A and 11A can be overlapped and fitted with almost no gap between them. Thus, the upper plates 11A and 11A are overlapped to constitute a pedestal portion.

  As described above, a bolt locking groove portion 13b made of a half cylinder is formed at the tip of each of the sandwiching pieces 13, 13.

  When the clamping members 10 and 10 are connected by screwing the clamping tool clamping bolt 21 and the clamping nut 22 and are advanced, the ribs 18 of the upper plate 11A disposed on the lower side are used. The projecting portion fits into the concave portion formed by the upper rib 18 so that the both sandwiching members 10 and 10 are fixed. At the same time, the tips of the sandwiching pieces 13 and 13 are close to each other, and both bolt locking groove portions 13b and 13b are bolts. The body B is locked and clamped.

  The effect of the on-roof fixture A of the present embodiment is the same as that of the second embodiment. Further, in the present embodiment, since the pedestal portion 11 is superposed, the on-roof fixture is configured to be sturdy. The effect that it is possible is also produced.

  In the first to third embodiments shown above, the washer portion accommodating space 13aa (see FIGS. 1 and 7) is exemplified by the opening, but the sandwiching piece 13 (on-roof placement portion 13a). In addition, a concave portion that is recessed upward (the upper portion is not open) may be provided, and the washer portion accommodating space may be configured by the concave space.

  Further, each of the on-roof fixtures A shown in the above three embodiments includes two pairs (four pieces) of the two opposing tightening protruding pieces 14, but is provided with either one pair. May be. Furthermore, in the said 3rd Embodiment, although bolting is carried out to the horizontal direction with respect to the clamp | tightening protrusion piece 14, the clamp | tightening protrusion piece which enabled it to carry out bolting in the up-down direction may be sufficient. In other words, in this case, it is only necessary that the tightening projection piece projecting from one clamping piece and the clamping projection piece projecting from the other sandwiching piece overlap vertically.
