Description

  The present invention relates to an on-roof fixture fixed on a roof by sandwiching a bolt body protruding from the top of the 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 Document 1).

  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 has a stacked connection structure that is connected and fixed by wearing. The roof mounting fixture to be attached to the corrugated roof has a tip portion relative to the shaft portion of the bolt body for connecting the roof material, which protrudes from the lower portion of the corrugated roof through the overlapped portion of the roof material. It can be installed by pinching with the facing pinching piece.

  Specifically, this on-roof fixture is formed in a substantially portal shape, tightening both leg pieces with fastening bolts and fastening nuts penetrating the leg pieces in the lateral direction, and starting from the lower ends of both leg pieces. Both clamping pieces extending so as to face each other have a structure for clamping the bolt body. Since the front end of the sandwiching piece is locked and fixed in a state where the tip of the sandwiching piece has bitten into the thread groove of the bolt body, the on-roof fixture is firmly fixed on the roof without being easily detached.

  However, as shown in FIG. 6 (a), this kind of on-roof fixture 100 is not stable because both leg pieces 112, 112 are in a floating state when the leg pieces 112, 112 are fastened. The roof mounting tool 100 may be attached in a tilted state as shown in FIG. Moreover, even if the roof mounting tool 100 is attached in a horizontal state, if a gap is formed between the leg pieces 112 and 112 and the upper surface of the roof Y as shown in FIG. There is a possibility that it cannot be done. In FIG. 6, 111 is a base, 113 is a clamping piece, 115 is a fastening bolt, 116 is a fastening nut, Y is a corrugated roof, B is a bolt body, C1 is a nut, and C2 is a washer.

  The present invention has been proposed in consideration of such a problem, and the object thereof is to be able to be attached to a bolt body protruding on the roof in a stable state and to maintain a stable attachment state. It is to provide a rooftop fixture.

In order to achieve the above-mentioned object, the on-roof fixture according to claim 1 has a pair of leg pieces, and the pair of leg pieces are fastened with a fastening bolt that passes through them, and protrudes on the roof. a structure was substantially gate roof fitting shape to be fixed to the bolt body, the leg pieces, a bolt body sandwiched possible plurality of split cylinder is Ri Contact are decorated, split cylindrical body, A split tube portion formed corresponding to a pair of leg pieces and formed in a semi-cylindrical shape, a flange projecting laterally from both ends of the peripheral surface of the split tube portion, and lower ends of the split tube portion and the hook portion A pressed portion extending so as to protrude more toward the leg piece, L-shaped in a front view, and a structure suspended from a tightening bolt so that the inner side surfaces of the split cylinder portion face each other. is, by tightening the leg, is pressed from the leg is pressed portion, with each other split tubular portion is clamped to the bolt body, so that the flange portions are in surface contact Characterized in that it is fixed.

The on-roof fixture according to claim 2 is characterized in that the inner side surface of the split cylinder has an uneven shape.

  According to the on-roof fixture according to claim 1, since the split cylinder body sandwiching the bolt body by tightening the leg piece is provided between the leg pieces, the lower end of the leg piece is the upper surface of the roof. If it is configured so that the tightening operation can be performed in a state of being in contact with the, a stable tightening operation can be performed. Therefore, it is possible to quickly perform the mounting operation and to mount the roof mounting fixture in a stable horizontal state.

  Moreover, since the on-roof fixture is attached in a state where the leg pieces are in contact with the upper surface of the roof, a stable state can be maintained even after construction.

Furthermore, since the pair of split cylinders are suspended from the tightening bolts, the on-roof fixture can be easily configured. A pair of split cylinders can be retrofitted to a conventional substantially gate-shaped rooftop fixture to constitute a real rooftop fixture.

Moreover, since the to-be-pressed part which protruded toward the leg piece is formed in the outer side part of a split cylinder, a split cylinder can be reliably fixed with respect to a bolt body.

According to the roof mounting tool according to claim 2, since the inner side surface of the split cylinder body has an uneven shape, the split cylinder body can be reliably locked to the bolt body, and can be stably fixed. The state can be maintained more reliably.

FIGS. 2 and 3 are front views showing the construction procedure of the roof mounting tool (an enlarged plan view of the main part is added to FIG. 3), and FIG. 4 shows the mounting state of the roof mounting tool. It is the front view and principal part enlarged plan view.

  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. In addition, the attachment object of the on-roof fixture A is not limited to a corrugated roof, A flat roof may be sufficient.

  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 mountain-shaped 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 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, as shown in FIG. 1A, the roof mounting fixture A includes a pedestal portion 11, a pair of leg pieces 12 and 12 extending downward from both ends thereof, and leg pieces 12 and 12, respectively. 1 (b) and FIG. 1 (c) are provided with a substantially gate-shaped fastening tool 10 integrally formed with extending pieces 13 and 13 bent so that the front ends thereof face each other from the lower end. Such a configuration includes a pair of split cylinders 20, 20.

  The roof mounting tool A is a bolt body B in which both leg pieces 12 and 12 of the tightening tool 10 are tightened so that the inner side surfaces of the split tube portions 21 and 21 of the split tube bodies 20 and 20 are close to each other. It is fixed in the state where it was pinched. The two leg pieces 12, 12 are tightened by screwing a tightening bolt 15 that passes through shaft holes 12 a, 12 a provided in the opposing leg pieces 12, 12 and a tightening nut 16. In the roof mounting fixture A shown in the figure, reinforcing ribs 11a and 12b are formed on the pedestal 11 and both leg pieces 12 and 12, respectively.

  As the tightening tool 10, as shown in the present embodiment, a structure in which both the extending pieces 13 and 13 can be clamped to the bolt body B can be used. That is, when the fastening tool 10 is used as a sandwiching tool, the extended piece 13 is used as a sandwiching piece. A concave portion 13a and a locking convex portion 13b are formed at the tip of the extended piece 13 so that the bolt body B can be directly clamped. In FIG. 1A, 13c is a reinforcing rib.

  In addition, as shown in FIG. 5, when attaching the on-roof mounting tool A to the top part Y1a of the top part Y1a of the folded plate roof Y that has been joined, without attaching the split cylinders 20 and 20, The roof mounting fixture A is constituted only by the fastener 10 (clamping tool), and the leg H1 of the goby portion H is clamped by the extended pieces 13 and 13 of the fastener 10 so that the roof mounting fixture A is attached. Can be used as

  The on-roof fixture A may be configured without using the fastener 10 that can be used as such a sandwiching tool, and other fasteners in which the extended pieces 13 and 13 are not formed. The configuration used may be used.

  On the other hand, the split cylinder body 20 that sandwiches the bolt body B includes a split cylinder portion 21 that is formed by dividing the cylinder vertically into a semi-cylindrical shape, and a flange portion 22 that protrudes laterally from both ends of the peripheral surface, The split tube portion 21 and the pressed portion 23 extending in the direction orthogonal to the flange portion 22 on the outer surface side of the split tube portion 21 from the lower ends of the flange portion 22 are L-shaped in front view.

  As shown in FIG. 1C, an insertion hole 21a is formed in the upper portion of the split cylinder portion 21, and the split cylinder body 20 is used in a state where the tightening bolt 15 is inserted into the insertion hole 21a. Is done. Further, a thread groove (female thread) is formed on the inner side surface of the split cylinder portion 21. The inner surface of the split cylinder portion 21 may be provided with other uneven shapes instead of the thread groove. In addition, since the collar part 22 is what assists clamping of the bolt body B so that it may mention later, the structure without the collar part 22 may be sufficient.

  Moreover, in this embodiment, since the roof mounting fixture A is the structure provided with the extension pieces 13 and 13 used also as a clamping piece by the usage condition shown in FIG. In order not to act as a sandwiching piece, in the state shown in FIG. 2, the separation dimension of the extended pieces 13 and 13 is required to be larger than the separation dimension of the split cylinder portions 21 and 21. .

  Such on-roof fixture A is attached to the folded plate roof Y by the following construction procedure.

  First, the split cylinders 20 and 20 are placed between the leg pieces 12 and 12 so that the inner side surfaces of the split cylinder parts 21 and 21 face each other, and the shaft holes 12a and 12a of the leg pieces 12 and 12 are formed. From one side, the shaft portion 15a of the tightening bolt 15 is passed through the insertion holes 21a and 21a of the split cylinders 20 and 20 toward the other shaft hole 12a, and the tightening nut is inserted from the distal end side of the tightening bolt 15. 16 is lightly tightened to temporarily fix (see FIG. 2). In order to expedite field work, it is desirable to perform temporary fixing work in advance.

  Next, from above the bolt body B erected on the folded plate roof Y, the bolt body B is fitted and inserted through the gap S between the split cylindrical bodies 20 and 20, and the roof mounting fixture A is attached to the top portion Y1a. Place on the top (see Figure 2 and Figure 3).

  In the state of FIG. 3, since both leg pieces 12 and 12 are in contact with the top surface of the top portion Y1a, the roof mounting fixture A is in a stable state, and the pedestal portion 11 is substantially parallel to the top surface of the top portion Y1a. It is kept in. Moreover, as shown in the enlarged plan view of FIG. 3, the inner surface of the split cylinder portions 21 and 21 of the split cylinder bodies 20 and 20 suspended from the tightening bolt 15 is connected to the shaft portion B1 of the bolt body B by a predetermined amount. It is in a state of being surrounded by an interval.

  When the tightening bolt 15 and the tightening nut 16 are tightened in this state, the pressed portion is pressed by the leg piece 12, and the inner side surfaces of the split tube portions 21, 21 of the split tube body 20 gradually become the shaft portion of the bolt body B. Close to the outer peripheral surface of B1, the screw groove on the inner surface bites into the screw groove of the shaft portion B1, and as shown in the enlarged plan view of FIG. Thus, the on-roof fixture A is fixed to the folded plate roof Y.

  Thus, the roof mounting tool A is fixed by the pair of split cylinders 20, 20 provided between the leg pieces 12, 12 of the tightening tool 10 by sandwiching the bolt body B. As long as the tightening state is maintained, that is, as long as the leg pieces 12 and 12 do not move outward, the split cylinders 20 and 20 are not displaced, and the firmly fixed state can be maintained.

  Furthermore, according to the roof mounting tool A, the tightening operation can be performed in a state where the lower ends of the leg pieces 12 and 12 are in contact with the upper surface of the roof, so that the roof mounting tool A does not tilt during the work. Installation work can be performed quickly in a stable state. Since the mounting operation can be performed in such a stable state, the on-roof mounting tool A can be mounted in a stable horizontal state.

  In order to enable the mounting operation in such a stable state, the lower end of the leg piece 12 is lower than the lower end position of the split cylinder 20 by at least the total height dimension of the washer C2 and the nut C1. Needless to say, it is necessary to use the tightening tool 10 and the split cylinder body 20 whose dimensional relationships are adjusted so as to be positioned.

  Also, as shown in the figure, when the bolt body B is sandwiched between the split cylinder portions 21 and 21, the flange portions 22 and 22 are in surface contact with each other. The sandwiching of the body B can be further stabilized, and if the unevenness such as a satin-like shape is formed on the surfaces of the flange portions 22 and 22 that are in contact with each other, the roof-mounted fixture A can be fixed more stably. be able to. Further, since the pressed portion 23 has a width corresponding to the provision of the flange portion 22, a stable pressing force can be obtained by the leg pieces 12.

  Further, the roof mounting fixture A has a configuration in which a pair of split cylinders 20 and 20, which are separate from the fastening tool 10, are added to the fastening tool 10 so as to correspond to the pair of leg pieces 12 and 12. The roof mounting fixture A can be configured.

  Further, since the split cylinders 20, 20 provided between the leg pieces 12, 12 have a structure in which the bolt body B is sandwiched, the ends of the extended pieces 13, 13 are attached to the shaft of the bolt body B even by tightening operation. The part B1 is not reached, and when it is clamped and fixed, the state shown in FIG. 4 is obtained. In other words, the roof mounting fixture A is configured such that the fastening tool 10 does not use the extending piece 13 as a sandwiching piece, so that the extending pieces 13 and 13 do not reach the bolt body B by a fastening operation. Also good. That is, the on-roof mounting tool A can be fixed to the folded plate roof Y with a tightening operation with a small amount of screwing, and the mounting operation can be further speeded up.

  Thus, when using the existing clamping tool as the fastening tool 10, the ends of the split cylinder bodies 20, 20 facing each other (between the split cylinder portions 21, 21) face each other of the extending pieces 13, 13. It is necessary to use the split cylinders 20 and 20 having a smaller separation dimension than between the tips.

  Further, since the split cylinder 20 is separate from the fastener 10, the split cylinder 20 is replaced with an appropriate size according to the dimensions of the bolt body B, the shape of other members, etc. What is necessary is just to comprise the tool A. FIG.

  Moreover, since this roof mounting fixture A is a structure which clamps the bolt body B with the split cylinders 20 and 20 comprised between the leg pieces 12 and 12, if such a roof mounting fixture A is used, When the tightening tool 10 is used as a clamping tool, it can be fixed to a bolt body B where the diameter of the shaft portion B1 is too small to be clamped.

  Furthermore, according to this on-roof mounting tool A, the leg pieces 12 and 12 are attached in contact with the top surface of the roof, so that it is possible to maintain a stable and rattling state even after construction.

  Further, in this embodiment, the pressed portion 23 of the split cylinder 20 is formed in a horizontal plate shape substantially parallel to the roof surface, but a pair of plate pieces extending in a vertical plate shape from both side ends of the flange portion 22. It may be constituted by. At least, a pressed part having a shape that can be directly pressed by the operation of the leg piece 12 by tightening may be formed behind the split cylinder part 21.
