  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.

  Tightening protrusions 14 are formed at both ends of the rising portion 13c so as to protrude outward in the penetration direction (width direction of the leg piece 12) of the central opening of the roof mounting fixture A. The piece 14 is configured to be clamped and clamped by a separate fastening body 15 in a state of being overlapped with the other opposing fastening projection piece 14.

  The tightening body 15 is made of metal or hard resin, and has a pair of sandwiching pieces 15a spaced apart from each other as shown in FIG. The clamped protruding pieces 14 and 14 can be sandwiched by the sandwiching piece 15a. In addition, a guide portion 15e whose inner side is obliquely cut is formed in the opening portion 15b at the tip of the sandwiching piece 15a so that it can be easily attached to the projecting piece 14 for tightening.

  Further, as shown in the perspective view of the main part in FIGS. 7A and 7B, groove portions 14a along the width direction are formed on the outer surfaces of the fastening projecting pieces 14 and 14, respectively. 15a can be fitted. This groove portion 14a constitutes a disengagement prevention means 20, whereby the lateral displacement and disengagement of the tightening body 15 can be prevented.

  On the other hand, as shown in the developed 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.

In particular, the fastening projecting piece 14 shown in the present embodiment projects outward, so that it is easy to perform the bolting operation and does not become a construction burden.

  Further, since the clamping pieces 13 and 13 can be fixed so as not to be opened by simply inserting the fastening body 15 into the fastening projecting pieces 14 and 14, the work can be performed quickly. Since it can be fixed more easily than bolting or caulking, it can work efficiently.

  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 projecting pieces 14 and 14 are clamped. By cooperation with the fastening by 15, it is possible to almost certainly prevent the on-roof 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. 6, since the roof mounting part 13a contacts the top surface of the top part Y1a in the circumference part of the washer part C, 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, a clamping piece 15a is press-fitted by hitting the head 15d of the fastening body 15 with a hammer or the like onto the fastening protrusions 14 and 14 which are in a superposed state in contact with each other or close to each other. The protruding pieces 14 and 14 are clamped and fixed (see FIG. 3).

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 fastening protruding piece 14 is formed that protrudes to the outside in the penetrating direction (width direction of the leg piece 12) of the central opening of the roof mounting fixture A. Has been. The fastening projecting piece 14 is configured to be clamped and clamped by a separate fastening body 15 in a state of being superposed on the other opposing fastening projecting piece 14.

  The fastening body 15 is made of metal or hard resin, and is attached from the lateral direction to the end of the fastening projection piece 14 as shown in FIG. 11A, and is the same as in the first embodiment. Although a thing may be used, a long thing may be used according to the length of the protrusion piece 14 for clamping. As shown in FIG. 11 (b), the holding piece 15 a may be long enough to be inserted into the inner space of the holding tool 1. Since the shape of the tightening body 15 is the same as that of the first embodiment, description thereof is omitted.

  Further, as in the first embodiment, it is desirable that a groove portion 14a (see FIG. 7) for fitting the fastening body 15 is formed on each outer surface of the fastening projecting pieces 14, 14.

  On the other hand, the center part of the on-roof mounting part 13a is opened, and the washer part accommodation space 13aa for accommodating the washer part C when the on-roof fixture 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.

  As described above, according to the roof mounting tool 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 are provided. By fastening 14 and 14 with the fastening body 15, it is possible to almost certainly prevent the sandwiched pieces 13 and 13 from being opened by an external force.

  Further, in this way, the bolt body B is locked to the male threaded portion B1 by the bolt locking groove portion 13b, the clamping to the bolt body B by the clamping piece 13, and the tightening projecting pieces 14 and 14 are tightened. By cooperating with the tightening and fixing by the body 15, it is possible to almost reliably prevent the roof mounting fixture A from coming out of the bolt body B and 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. 11, 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. 12, 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.
