Description

  The present invention relates to an on-roof fixture that is mounted on a roof by being sandwiched between bolt bodies protruding from the top of a corrugated roof.

  In general, various devices and parts such as TV antennas, air conditioners, solar panels, heat shield sheets, etc. are placed on the top of corrugated roofs such as folded plate roofs (square corrugated roofs) and round corrugated roofs. Conventionally, various on-roof fixtures for attaching various devices and members on the roof have been proposed (see, for example, Patent Documents 1 and 2).

  The roof described in Patent Document 1 is a peak portion of a corrugated roof in which mountain portions and trough portions are alternately continuous, and a superposed portion formed by overlapping adjacent roof materials is screwed with a bolt body and a nut. It is structured to be connected and fixed by wearing. And the on-roof fixture to be attached to the corrugated roof has a tip opposite to the male thread portion of the bolt body for connecting the roof material that protrudes from the lower portion of the corrugated roof through the overlapping portion. It can be installed by pinching with a pinching piece.

  Specifically, this on-roof fixture is constructed by tightening both leg pieces with tightening bolts and nuts that penetrate the both leg pieces of the sandwiching tool formed in a substantially portal shape in the lateral direction, and from the lower ends of both leg pieces. Both clamping pieces extending so as to face each other are clamped to the bolt body. Therefore, since the tip of the sandwiching piece is locked and fixed in a state where the tip of the sandwiching piece has bitten into the screw groove of the bolt body, the on-roof fixture is firmly fixed on the roof without being easily detached.

  Moreover, the thing of patent document 2 is comprised from a pair of clamping member by which the clamping tool was fulcrum-connected, and has a structure clamped with respect to the goby part in a top part, but this kind of thing is piled up. Even when it is applied to a type roof and formed into a structure that is clamped to a bolt body with both clamping pieces, it can be assumed that the on-roof fixture is similarly firmly fixed on the roof.

JP 2010-77692 A Japanese Patent No. 3368374

  By the way, in the roof mounting fixture of the type that attaches to the bolt body protruding from the top, in order to fix the roof mounting fixture so as not to wobble on the roof, both the clamping pieces are firmly clamped to the bolt body. Furthermore, it is desirable that the attachment is made so that the entire lower surface or a part of each sandwiching piece comes into contact with the roof, that is, the roof mounting fixture itself is placed on the top.

  However, in such an on-roof fixture, the bolt body is fixed to the roof by screwing with a nut, and the nut is generally attached via a washer. And it will be even higher than the nut attached on it. Therefore, considering the sandwiched portion and placing the rooftop fixture itself on the top, especially in the case of a mountain washer, the rooftop fixture itself is not modified unless the shape of the sandwiched piece is devised. It is difficult to place it on top.

  That is, in order to realize stable installation of the roof mounting fixture, for example, as shown in FIG. 11A, the sandwiching piece 110 of the roof mounting fixture 100 is avoided so as to avoid the nut C1 and the washer C2. And the bolt body B is clamped, and the base end 111 (the lower end of the leg piece 120) must be brought into contact with the top Y1a of the corrugated roof Y.

  However, even when the sandwiching piece 110 is inclined upward as described above, the roof mounting tool 100 is installed so that both leg pieces 120 and 120 are arranged along the ridgeline direction of the top Y1a (FIG. 11A). (See Fig. 11 (b)), since the washer C2 is arranged at the center in the width direction of the top Y1a, the top surface of the top Y1a No space for abutting the base ends 111, 111 of the sandwiching pieces 110, 110 is formed, and stable installation cannot be expected. Reference numerals 130 and 131 in FIGS. 11A and 11B are tightening bolts and nuts for tightening the leg pieces 120 and 120.

  The present invention has been proposed in view of such circumstances, and its purpose is to attach to the top of the corrugated roof from which the bolt body protrudes through the washer, regardless of the direction of attachment to the top. An object of the present invention is to provide an on-roof fixture that can be firmly and stably attached.

  In order to achieve the above object, the on-roof fixture according to claim 1 is provided with a substantially portal-shaped sandwiching tool having a pair of sandwiching pieces opposed to each other at the lower ends, In the roof mounting fixture in which the clamping pieces are brought close to each other and clamped to the bolt body protruding from the top of the corrugated roof through the washer, the clamping piece is related to the male thread portion of the bolt body. It is characterized by comprising a locking projection piece to be stopped and a roof mounting part in which a washer part accommodating space for accommodating the washer part is formed.

  In the on-roof fixture according to claim 2, the sandwiching tool is integrally formed including a leg piece in which the sandwiching piece is bent at the lower end and a pedestal part in which the leg piece is extended at both ends. In addition, the pair of sandwich pieces are brought close to each other by tightening the pair of leg pieces.

  In the on-roof fixture according to claim 3, the sandwiching tool is configured by connecting a pair of sandwiching members in which the sandwiching pieces are bent at the lower ends thereof so as to be freely opened and closed.

  According to the on-roof fixture according to claim 1, it is possible to firmly lock and clamp the bolt body protruding from the top of the corrugated roof by the locking projection formed on the clamping piece, and to accommodate the washer portion. The roof mounting part in which the void is formed ensures that the top surface of the top part can be securely mounted in any direction with respect to the top part without touching the washer part arranged on the top surface of the top part. Can be placed. Therefore, the clamping of the clamping piece to the bolt body does not wobble due to the placement by the contact with the top of the roof mounting part, and the installation of the roof mounting fixture on the corrugated roof is stable.

  According to the roof mounting tool of claim 2, the sandwiching tool is integrally formed including a leg piece in which the sandwich piece is bent at the lower end and a pedestal portion in which the leg piece extends at both ends. Therefore, the sandwiching tool can be constructed in a sturdy and simple shape.

  In addition, since the sandwiching tool is integrally formed, there is almost no possibility that a shift occurs between the sandwiched pieces.

  Further, since the pair of leg pieces are tightened to bring the pair of sandwich pieces close to each other, a tightening structure can be realized simply by providing a tightening bolt or the like for tightening the pair of leg pieces. Can be simplified.

  According to the roof mounting tool of claim 3, the clamping tool is formed by connecting a pair of clamping members in which the clamping pieces are bent at the lower ends thereof so as to be freely opened and closed. Regardless of this, the clamping piece can be clamped to the bolt body by a labor-saving and simple operation.

FIG. 5 is a view 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 lap-type joining structure in which the bolt body B and the nut C1 are connected by screwing at the overlapping portion.

  In the illustrated example, the nut C1 constitutes a washer portion C together with a washer C2 (a mountain washer in the illustrated example) 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. In addition, the attachment position of the bolt body B for attaching the roof mounting fixture A is not limited to the overlapping portion of the adjacent folded plate roof material, and the bolt body B may be attached to the other top portion Y1a using the support fitting Y3. .

  This 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 above-described bolt body B for connecting overlapping portions protruding upward from the top Y1a of the folded plate roof Y. It has become.

  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 pinching tool 1 integrally formed with the pinching pieces 13 and 13 bent in the direction, and the both leg pieces 12 and 12 are fastened, and the front-end | tip of both pinching pieces 13 and 13 is comprised. Are made close to each other and 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 illustrated example, reinforcing bases 11x and 12x are formed on the pedestal 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 thereof. Folded, a locking recess 13b is formed at a location facing the bolt body B, and a locking projection 13ba that locks to the male thread B1 of the bolt body B is formed at the bottom of the locking recess 13b. ing.

  As shown in the developed view of the sandwiched piece portion of FIG. 1B, the roof mounting portion 13a has a large opening at the center and a recess (locking recess 13b) communicating with the opening. Has been. When the sandwiching piece 13 is formed by bending this sandwiching piece plate material, the washer part accommodation space that accommodates (avoids) the washer part C when the rooftop fixture A is installed on the top Y1a by the opening. 13aa is formed.

  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. If the washer part C is composed only of the nut C1, it is sufficient to provide the washer part accommodating space 13aa with a small volume corresponding to the size, but it is also possible to use one corresponding to the washer part C as shown in the figure. Needless to say.

  Further, the locking protrusion 13ba is locked to the male screw portion B1 by holding the bolt body B at both locking recesses 13b and 13b by tightening the leg piece 12. In this way, the locking protrusion 13ba meshes with the thread groove of the male screw portion B1, and a firm clamping relationship is formed, whereby the roof mounting fixture A is fixed to the bolt body B. In addition, it is desirable to form this latching protrusion 13ba slightly upward. In order to strengthen the locking, both side portions of the locking recess 13b may also be bitten into the male screw portion B1.

  Moreover, as shown in FIG. 2, 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.

Moreover, since it is the same as that of 1st Embodiment (FIG. 5) about explanatory drawing of the mounting state of the roof mounting fixture A, illustration is abbreviate | 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 locking protrusion 13b that is bent upward at the tip and further folded back to form a locking recess 13b at a position facing the bolt body B, and that is locked to the male threaded portion B1 of the bolt body B at the bottom. 13ba is formed.

  The roof mounting part 13a has an opening at the center, and the opening forms a washer part accommodating space 13aa that accommodates the washer part C when the roof mounting tool A is installed on the top Y1a. 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.

  In addition, as with the first embodiment, the locking recess 13b is shown in which the locking protrusion 13ba is formed at the bottom, but is not limited thereto, and only the locking protrusion 13ba is formed. May be good.

  Thus, according to this on-roof fixture A, the locking recess 13b and the locking projection 13ba can be firmly clamped to the bolt body B protruding from the top Y1a of the folded plate roof Y, and the top Y1a can be clamped. The clamping of the clamping pieces 13 and 13 to the bolt body B does not wobble due to the contact and placement, and the installation of the on-roof fixture A on the folded plate roof Y is stable.

  Further, as shown in FIG. 6, even when the washer C2 has a large diameter 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 meshed so that the bolt through holes 11e are aligned with each other, and the bolt through holes 11e are aligned. The fastening recesses 13b and 13b provided at the front ends 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. 7, 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.

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.

  In this way, the stepped portion 11c is formed along the bolt through hole 11e and the cut groove 11d provided in the center of the upper plate 11A, so that when the front end portion 11b of the upper plate 11A is opened, it is polymerized 2 The upper plate 11A of the sheet is 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 clamping member 10 becomes smaller, and there is no possibility of wobbling. , A more stable shape can be obtained. The upper plates 11A and 11A thus overlapped 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.
