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.

  In general, on the top surface of corrugated roofs such as folded plate roofs (corner corrugated roofs) and round corrugated roofs, for example, on-roof fixtures such as TV antennas, air conditioners, solar cell panels, heat shield sheets, etc. In the past, various on-roof fixtures for mounting such an on-roof fixture on the roof have been proposed (see, for example, Patent Document 1).

  In particular, in a structure in which the overlapping portion of adjacent roof materials stacked on the top of the corrugated roof is fixed by screwing bolts and nuts, the top penetrates the roof from below the roof and protrudes onto the roof. In addition, an on-roof fixture constituted by a clamping tool that clamps and fixes a bolt body for connecting roofing materials with opposing clamping pieces has also been proposed.

  This sandwiching tool includes a main body portion having both leg pieces and a substantially gate-shaped cross section, and both sandwiching pieces extending so as to face each other from the lower ends of both leg pieces. It has a structure in which both clamping pieces are clamped and attached to the bolt body by tightening with tightening bolts and nuts. According to such an attachment structure, since the leading end portions of both the sandwiching pieces can be fixed by biting into the thread grooves of the bolt body, the possibility that the sandwiching tool is detached is low.

Japanese Patent No. 3368374

  However, in the case of the on-roof mounting tool that is mounted by being clamped to the bolt body, there are the following problems.

  6A and 6B are schematic explanatory views showing two examples of attachment examples of the conventional roof mounting fixture to be attached to the corrugated roof, and FIG. 6A is a side edge of the corrugated roof Y. FIG. FIG. 6 (b) shows an example in which the goby part D formed by the gourd joint structure at the top Y1a of the peak part Y1 is attached to the leg part D1, and FIG. This is an example of pinching. Both are examples in which the heat shield sheet 110 is fixed and attached above each on-roof fixture, and both examples use the on-roof fixture (the sandwiching tool 100) of the same type and the same structure. In addition, the attachment example (direction) with respect to the top part Y1a differs in the attachment example of the roof fixture shown to FIG. 6 (a), (b).

  When the thermal insulation sheet 110 is fixed and stretched to a plurality of sandwiching tools 100 as shown in the figure, for example, when snow is accumulated on the thermal insulation sheet 110, it is arranged on both sides of the thermal insulation sheet 110 by the weight of the snow S. When the rooftop fixture 100 is pulled in the center, there is a risk that the sandwich piece 101 sandwiched between the goby portion D and the bolt body B will rise while tilting. Further, when the heat shield sheet 110 is dampened by rainwater or the like and then dried, the heat shield sheet 110 may contract, and in that case, the same phenomenon may occur.

  In this case, the pinching tool 100 attached to the goby portion D may be slightly displaced or tilted, but the upper portion of the goby portion D protrudes in the lateral direction, so that the pinching tool 100 comes out of the goze portion D. Although there is almost no fear (refer to FIG. 6A), in the case where it is attached to the bolt body B, the clamping tool 100 is gradually tilted by a strong pulling force, and the tip of the clamping piece 101 is the bolt body B. There is a possibility that the shaft part B1 may come off while being lifted up (see FIG. 6B).

  Further, in the case of a roof mounting tool to be mounted by clamping to the bolt body B, it is necessary to arrange a nut for bolting on the top surface of the top portion Y1a. Further, there is a possibility that the sandwiching piece 101 is lifted from the top Y1a, and the sandwiching tool 100 is rotated or wobbled.

  Therefore, in the roof mounting tool of the type that is attached by being clamped to such a bolt body B, the structure is less likely to cause slack such as tilting, sliding up, rotation, wobble, etc. of the clamping tool due to external force. Things were needed.

  The present invention has been proposed in view of such circumstances, and its purpose is to maintain a stable state without the possibility of slipping or loosening of the sandwiching tool, and for a plurality of on-roof fixtures. An object of the present invention is to provide an on-roof fixture and a mounting structure for the on-roof fixture that do not cause the sandwiching tool to tilt or come off due to the load of the on-roof fixture attached thereon.

  In order to achieve the above object, an on-roof fixture according to claim 1 includes a main body portion having both leg pieces and formed in a substantially gate-like cross section, and bends and extends so as to face each lower end of both leg pieces. At least a pair of sandwiched pieces provided, and tightening the both leg pieces by screwing a tightening bolt and a tightening nut so that the sandwiched pieces are close to each other, and the top of the corrugated roof In the roof mounting tool provided with a clamping tool structured to be clamped by a more projecting bolt body, the clamping bolt and the clamping nut for tightening the both leg pieces are screwed together so that the clamping tool is And a reinforcing plate having a connecting piece connected to the sandwiching tool on the outside of at least one of the leg pieces, and a wall piece standing upright in an orthogonal state to the connecting piece. The reinforcing plate is disposed on the top of the corrugated roof, and the bolt body Characterized in that the structure for supporting the clamping device which is clamped.

  According to a second aspect of the present invention, there is provided the on-roof fixture according to the first aspect, wherein the reinforcing plate has the connecting piece 1 piece and the wall piece 1 piece and is formed in an L shape in plan view.

  According to a third aspect of the present invention, in the on-roof fixture according to the first aspect, the reinforcing plate body is formed in a box shape having the one piece of the connecting piece and the two pieces of the wall piece.

Further, a reinforcing plate 16 having an L-shape in a plan view is fixed to the outside of the leg piece 11b) to which the nut 14 is attached.

  As shown in FIG. 2, the reinforcing plate 16 has an L shape in plan view, and includes a connecting piece 18 and a piece of wall piece 19 that extends orthogonally from one end of the connecting piece 18. A notch-like long hole 16a opened upward is formed in one leg piece 11b by screwing between a tightening bolt 13 inserted through the long hole 16a and a reinforcing plate mounting nut 17. It has a fixed structure. Further, a fastening nut 14 for fastening the clamping tool 10A is disposed between the leg piece 11b and the connecting piece 18.

  In this way, the reinforcing plate 16 is fixed by the tightening bolt 13 and the reinforcing plate mounting nut 17, and the clamping tool 10 </ b> A is tightened by screwing the tightening nut 14 to the tightening bolt 13. Is held, the looseness with the sandwiching tool 10A is suppressed.

  The reinforcing plate 16 is made of a metal plate or a hard resin plate, and is preferably formed by bending a single flat plate into an L shape to maintain strength. However, the two flat plates are welded, welded, or bonded. It may be a thing. As another form, it may have a T-shape in a plan view as shown in FIG. 5B as having a single wall piece 19 extending orthogonally to the connecting piece 18.

  According to such a reinforcing plate 16, the wall piece 19 is in an orthogonal state with respect to the leg piece 11b of the sandwiching tool 10A and stands on the top 41a of the folded plate roof 40. When an external force is applied in the direction from the base plate to the reinforcing plate 16, it can be a sufficient support to resist it, so that the sandwiching tool 10 </ b> A can be prevented from tilting or sliding up, and the sandwiching tool 10 </ b> A can be stabilized. Can be maintained in a state. As will be described later with reference to FIG. 5, the configuration of the reinforcing plate 16 is effective when a sheet or the like is stretched over the plurality of on-roof fixtures 10. Further, in the present embodiment, the reinforcing plate 16 is formed by integrally connecting the connecting piece 18 and the wall piece 19, and thus can particularly firmly support the sandwiching tool 10 </ b> A.

  Further, the reinforcing plate body is attached in a state where both the clamping pieces 12 and 12 are clamped to the bolt body 21 protruding from the top 41a of the folded plate roof 40 by screwing the clamping bolt 13 and the clamping nut 14. Since the reinforcing plate 16 is fixed to the tightening bolt 13 with the nut 17, the on-roof fixture 10 can be attached in a very easy operation and in a short time.

  Regarding the method for attaching the roof mounting fixture 10 according to the present embodiment, first, the shaft portion 13a of the tightening bolt 13 is passed through the shaft holes 11ba and 11ba of both leg pieces 11b and 11b, and then the distal end side of the tightening bolt 13 is used. In FIG. 4, the leg pieces 11b, 11b are lightly fastened by the tightening nut 14 to temporarily fix them, and the clamping device 10A is bolted from above the bolt body 21 protruding from the top 41a through the gap 15 between the leg pieces 11b, 11b. 21 is inserted (see FIG. 3A).

  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 come close to each other by the tightening force, and both sandwiched pieces 12 and 12 at the lower ends of the both leg pieces 11b and 11b. Are also close to each other, and both recesses 12c and 12c of both sandwiching pieces 12 and 12 sandwich the shaft portion 21a of the bolt body 21, and the cut and raised piece 12d bites into the thread groove of the bolt body 21 so that the sandwiching is performed. The tool 10 </ b> A is fixed to the folded plate roof 40. (See FIG. 3B).

  Further, the reinforcing plate 16 is placed on the top 41a so that the tightening bolt 13 protruding from the tightening nut 14 passes through the long hole 16a of the reinforcing plate 16, and protrudes from the long hole 16a. The reinforcing plate 16 is connected and fixed to the clamping tool 10A by screwing the reinforcing plate attachment nut 17 to the tightening bolt 13 (see FIG. 3B).

  According to the roof mount 10 thus mounted, various devices and members can be mounted on the main body 11 of the roof mount 10 in a stable state.

  Further, since the reinforcing plate 16 is connected and fixed to the sandwiching tool 10A, even when the sandwiching tool 10A is installed without contacting the top 41a surface as in the present embodiment, the sandwiching tool 10A. Can be prevented from rotating or wobbling. In particular, since the wall piece 19 is orthogonal to the leg piece 11b of the sandwiching tool 10A and stands upright on the top portion 41a, the wall piece 19 can exhibit a high resistance to an external force that tries to push it down. It can be maintained in a solid and stable state.

  Further, the reinforcing plate 16 has a configuration in which the bottom portions of the connecting piece 18 and the wall piece 19 are brought into contact with the upper surface of the folded plate roof 40 to stabilize the sandwiching tool 10A. There is no need to provide a spacer to stabilize. As a result, the position of the on-roof fixture 10 does not increase as in the case where the spacer is provided under the sandwiching tool 10A, and the margin of the bolt body 21 can be increased.

  When the reinforcing plate body 16 is attached by the reinforcing plate body mounting nut 17, the bent base portion 12a and the connecting piece 18 are brought into close contact with each other. More preferably, a spring washer, a washer or the like is interposed between the piece 18 and the reinforcing plate attachment nut 17 for position adjustment and locking prevention.

  Next, with reference to FIG. 4, a mounting structure of the roof mounting tool 10 to the folded plate roof 40 and a fixing structure of the roof mounting object will be described.

  In the example of FIG. 4, a heat shield sheet 30 is shown as an attachment on the roof. The heat shield sheet 30 is stretched over and fixed to a plurality of on-roof fixtures 10 disposed on each of the plurality of top portions 41a.

  Specifically, a plurality of on-roof fixtures 10 are juxtaposed on the top 41a of the folded plate roof 40, and a plurality of on-roof fixtures 10 are similarly juxtaposed on the other top 41a. In each of the sandwiching fixtures 10A of the two roof mounting fixtures 10 at both ends of the plurality of roof mounting fixtures 10 arranged on each top 41a, both leg pieces 11b and 11b are arranged along the longitudinal direction of the top 41a. It is arranged in. In addition, 10 A of intermediate | middle clamping tools may be distribute | arranged to the direction similar to the clamping tool 10A of both ends like the example of a figure, and may be distribute | arranged to another direction.

  And the reinforcement board 16 is fixed to the inner leg piece 11b with respect to each of the clamping tool 10A of both ends. In other words, when the heat shield sheet 30 is stretched as in the present embodiment, the reinforcing plate 16 is attached to the inner leg piece 11 b facing in the direction pulled by the heat shield sheet 30.

  In addition, it is desirable to attach the reinforcing plate 16 to one or both of the leg pieces 11b and 11b as shown in the example from the viewpoint of further increasing the attachment strength of the intermediate sandwiching tool 10A. 4 shows the heat shield sheet 30 as an example of an on-roof attachment mounted on the plurality of on-roof attachments 10, but the above roof is also used when a television antenna, an air conditioner, or a solar panel is attached. An attachment structure of the upper fixture can be applied.

  Thus, among the plurality of on-roof fixtures 10 arranged side by side on the top 41a, the reinforcing plate 16 corresponding to each of the sandwiching fixtures 10A of the two on-roof fixtures 10 located at both ends is provided. Since both are fixed to the inner leg piece 11b, when pulled by the heat shield sheet 30, the force against the pulling force of the heat shield sheet 30 is exerted from the inside like a support rod for the sandwiching tool 10A. It is possible to reliably prevent the sandwiching tool 10 </ b> A from being tilted or pulled out by acting.

  Next, another embodiment of the present invention will be described. FIG. 5A is a perspective view showing a reinforcing plate used in the second embodiment. Note that FIG. 5B is as described above.

  The reinforcing plate 16 used for the on-roof fixture is formed in a box shape and has a U shape in plan view. That is, the reinforcing plate 16 includes one connecting piece 18 and two wall pieces 19 and 19. The box-shaped reinforcing plate 16 is an integral member made of a metal plate or a hard resin plate, and the connecting piece 18 and the wall pieces 19 and 19 are in an orthogonal state. That is, it is formed by bending one flat plate into a U-shape, or welding, welding or adhering three flat plates. The connecting piece 18 is formed with a notch-like long hole 16a opened upward.

  According to such a box-shaped reinforcing plate 16, the two wall pieces 19, 19 correspond to both side ends of the leg piece 11 b of the clamping tool 10 </ b> A (not shown in FIG. 4, see FIG. 1, etc.). Thus, the sandwiching tool 10A can be fixed in a more stable state.

  Since the construction method and the mounting structure of the box-shaped reinforcing plate 16 and the sandwiching tool 10A are the same as those in the first embodiment, illustration and description are omitted.

  Each of the two types of reinforcing plate 16 shown above is composed of a connecting piece 18 and one or two pieces of wall pieces 19, but having a bottom plate piece in surface contact with the top surface of the top portion 41a. It may be.
