The superposed base parts 11 and 11 and the board part 21 arranged thereon are fixed by bolts 31 and nuts 32.

  Next, each embodiment will be described. First, the roof article fixture according to the embodiment shown in FIGS. 1 to 4 will be described.

  As shown in FIGS. 2 to 4, the on-roof article mounting tool 1 is mounted on the folded plate roof 40.

  The folded plate roof 40 is a roof in which the mountain parts 41 and the valley parts 43 are alternately continued, and is a roof formed by connecting a plurality of roofing materials at the top part 42 of the mountain part 41. Reference numeral 49 denotes a holding member that holds the shape of the folded plate roof 40 from below.

  The on-roof article attachment tool 1 is attached and fixed to a projecting portion made of a goby portion 45 projecting above the top portion 42 of the folded plate roof 40.

  As described above, the on-roof article fixture 1 includes a pair of clamping members 10 and 10 and a fastening cover 20 as main components, and these are fixed by bolts 31 and nuts 32. .

  In the present embodiment, the pair of sandwiching members 10 and 10 have the same shape, and each of the sandwiching members 10 has a rectangular base portion 11 in plan view and one end portion (one edge portion). A leg portion 13 extending downward and a sandwiching piece 14 extending from the lower end of the leg portion 13 to the lower side of the pedestal portion 11 substantially parallel to the pedestal portion 11 are provided.

  The pedestal portion 11 includes a bent piece 12 that is bent downward at a side edge that is opposite to the side edge provided with the leg 13. A step portion 11c that is parallel to these edges and has an inclined surface is formed at the approximate center between the edge part on the leg part 13 side of the pedestal part 11 and the edge part on the bent piece 12 side. The flat plate portion 11e on the bent piece 12 side is arranged at a position lower than the flat plate portion 11d on the leg portion side.

  A bolt insertion hole 11a is formed at approximately the center of the stepped portion 11c so as to straddle both the flat plate portions 11d and 11e, and from the bolt insertion hole 11a along the stepped portion 11c to the edge on the leg 13 side. A notch groove 11b that communicates with the outside of one of the adjacent side edges (edges) is formed.

  The edge of the bolt insertion hole 11a on the side of the flat plate portion 11d on the leg portion 13 side is rounded so as to match the shape of the shaft portion of the bolt 31, but the flat plate portion on the bent piece 12 side of the bolt insertion hole 11a. The edge on the 11e side is square.

  The leg 13 extends downward so as to open slightly outward (see FIG. 1). Further, the sandwiching piece 14 extends to a lower position in the middle of the pedestal portion 11 below the pedestal portion 11, and a pressing portion 14a protruding upward is formed at the tip thereof (see FIG. 1).

  The holding tool A is configured by combining two holding members 10 having such a structure. In addition, although a pair of clamping member 10 and 10 shown to the example of a figure are the same shapes, it is not limited to it.

  The clamping tool A is formed by connecting a pair of clamping members 10 and 10 with fulcrums so that the clamping pieces 14 and 14 can be opened and closed. Specifically, the notch grooves 11b and 11b of the pedestal parts 11 and 11 are inserted into each other, and the pedestal parts 11 and 11 are overlapped to form the holding tool A. Thus, in a state where the two sandwiching members 10 and 10 are simply combined and connected, the portions of the notch grooves 11b and 11b serve as fulcrums in front view, and can be opened and closed like scissors (FIGS. 2 to 2). 4).

  In this state, the flat plate portions 11e and 11e on the side of the bent portions 12 and 12 of the pedestal portions 11 and 11 of the both clamping members 10 and 10 are all arranged on the lower side and are formed by two bolt insertion holes 11a and 11a. The opening on the lower surface side of the bolt through hole is formed in a square shape such that the root corner portion 31a of the bolt 31 is fitted by the square shape of the edge portion of both bolt insertion holes 11a, 11a.

  The on-roof article mounting tool 1 is formed by adding a fastening cover 20 for fixing the holding tool A formed as described above in a state where the holding pieces 14 and 14 are closed. As described above, the fastening cover 20 includes the board portion 21 having the bolt insertion holes 21a and the hanging pieces 22 and 22 hanging from both ends of the board portion 21.

  The clamping tool A and the fastening cover 20 are coupled to each other in a fixed state by superimposing and fixing the base parts 11 and 11 and the board part 21 by screwing bolts 31 and nuts 32. As other members for connection, a bolt stop 33, a flat washer 34, and a spring washer 35 are used. As will be described later, the bolting 33 is preferably used for efficient attachment to the folded plate roof 40, but the flat washer 34 and the spring washer 35 may be selectively used. Further, as the bolt 31, it is desirable to use a root bolt as shown in the figure.

  The clamping tool A and the fastening cover 20 are fixed to the cross section 45 of the folded plate roof 40 in a state of being connected and fixed in this way. Hereinafter, this procedure will be described with reference to FIGS.

  First, as shown in FIG. 2, a pair of clamping members 10 and 10 are connected to form a clamping tool A, and bolts 31 are passed from below through bolt through holes formed by both bolt insertion holes 11a and 11a. 33 is passed through the shaft portion 31b of the bolt 31 protruding upward so that the bolt 31 does not fall and the holding tool A can be opened and closed.

  2, the shaft portion 31b of the bolt 31 protruding upward is passed through the bolt insertion hole 21a (see FIG. 1) of the tightening cover 20, and the tightening cover 20 is attached, and the flat washer 34, the spring washer 35 is attached, and the nut 32 is screwed and temporarily fixed.

  Next, as shown in FIG. 3, the holding tool A covered with the fastening cover 20 is placed on the top 42 of the folded plate roof 40 with both the holding pieces 14 and 14 open. 14 and 14 are placed so as to sandwich the goby portion 45 from both sides. At this time, it is desirable to pull the bolt 31 upward and fit the root corner portion 31a into the square opening of the bolt through-hole so that the bolt 31 does not fall further downward with the bolt stopper 33.

  Thus, the clamping tool A is temporarily fixed by lifting the bolt 31 firmly upward and pressing the fastening cover 20 downward. In other words, the pedestals 11 and 11 of the both clamping members 10 and 10 connected to the fulcrum are superposed so that they are parallel to each other, and at the same time, both the leg portions 13 and 13 are closed and the space between the clamping pieces 14 and 14 is narrowed. As a result, the sandwiching pieces 14 and 14 are gradually pressed against the outer surface of the upright base portion 45a of the goby portion 45.

  When the clamping cover 20 is sufficiently pressed downward, the upper end portion of the clamping tool A fits into the space between the hanging pieces 22 and 22 of the clamping cover 20, and at the same time, both the leg portions 13 and 13 are further tightened. The lateral outer surfaces of the pressing portions 14 a and 14 a of the sandwiching pieces 14 and 14 are further pressed against the outer surface of the upright base portion 45 a of the goby portion 45.

  Then, by firmly screwing the nut 32 to the bolt 31, the overlapped both pedestal portions 11, 11 and the substrate portion 21 of the fastening cover 20 thereon are firmly tightened in the vertical direction, and at the same time, Both the sandwiching pieces 14 and 14 are fixed in a state where their tips press the standing base portion 45a of the goby portion 45 from both sides (see FIG. 4). Note that the bolt 31 and the nut 32 are screwed and screwed together because the head of the bolt 31 is below the pedestal 11, and the nut 31 is tightened, but the bolt 31 is on the back side of the bolt through hole. Since the rotation of the bolt 31 is prevented by the opening and the bolt 31 is prevented from dropping by the bolt stopper 33, the tightening operation can be performed efficiently.

  In this way, the on-roof article attachment tool 1 is attached and fixed to the cross section 45 of the folded plate roof 40. And the rail (not shown) for solar panel attachment and various articles | goods on a roof (not shown) can be attached to the axial part 31b of the volt | bolt 31 which protruded above the fastening cover 20. FIG.

  As described above, the article mounting tool 1 on the roof is configured to tighten the leg portions 13 and 13 of the clamping members 10 and 10 from the outside with the hanging pieces 22 and 22 of the fastening cover 20, that is, the direction in which the leg portions 13 and 13 open. Since the leg portions 13 and 13 are prevented from opening, the loosening and displacement between the holding members 10 and 10, particularly between the holding pieces 14 and 14 are prevented. Can do.

  In addition, the roof article mounting tool 1 is configured to connect the pedestals 11 and 11 of the sandwiching members 10 and 10 in a crossing manner like scissors, and since it is necessary to be able to open and close in the crossing state, the cutout groove 11b. , 11b is preferably formed in a dimension having play. If there is such play, even if only the clamping members 10 and 10 are tightened and fixed with the bolts 31 and nuts 32, there is a risk that they will be displaced between the clamping members 10 and 10, and loosening may occur. Since the tool 1 is configured to be tightened by the tightening cover 20, it is difficult for displacement and loosening to occur, and this is particularly effective for such a cross-over type.

  Next, the on-roof article attachment tool 1 attached to the bolt body 47 protruding from the top 42 of the folded plate roof 40 will be described with reference to FIGS. 5 and 6.

  The folded plate roof 40 has a stacked continuous structure in which both roof materials adjacent to each other are overlapped at the mountain portion 41 and connected and fixed by a bolt body 47. A shaft portion 47 a of a bolt body 47 protrudes from the top portion 42 of the peak portion 41, and the bolt body 47 is fixed by a nut 48 with a washer.

  The on-roof article attachment tool 1 has a structure corresponding to the protruding portion formed by the shaft portion 47a of the bolt body 47. Specifically, the shape of the clamping piece 14 of the clamping member 10 is different from that of FIG. In addition, since parts other than the clamping piece 14 of the clamping member 10 and the fastening cover 20 have the same shape and the same structure as those in FIG. 1, description of those shapes and structures is omitted. Moreover, since the attachment procedure of the on-roof article attachment tool 1 is substantially the same as that in FIG. 1, only the state of being attached to the folded plate roof 40 is illustrated, and illustration and description of the attachment procedure are omitted.

  The clamping piece 14 of the clamping member 10 is inclined slightly upward toward the tip. This is to prevent the clamping pieces 14 and 14 from coming into contact with the nuts with washers 48 and to securely clamp the shaft portion 47a of the bolt body 47.

  A locking recess 14 b for locking the shaft portion 47 a of the bolt body 47 is formed at the center of the tip of the clamping piece 14. A locking claw 14c cut and raised slightly upward is formed at the bottom of the locking recess 14b. In the clamping tool A, when the clamping members 10 and 10 are tightened, both the locking recesses 14b and 14b of the both clamping pieces 14 and 14 clamp the shaft portion 47a of the bolt body 47, and the locking claws 14c and 14c are the shaft portions. By being locked in the thread groove 47a, the bolt body 47 is fixed. The structure for fixing the bolt body 47 to the shaft portion 47a is not limited to the one using the locking recess 14b, and various structures can be employed.

Then further about the roof quality goods article fixture according to another embodiment (reference example) will be described with reference to FIG. 7 (a) (b).

  This on-roof article attachment tool 1 is attached to the cross section 45 of the folded plate roof 40 in the same manner as in FIG. Since this folded plate roof 40 is the same as that shown in FIG. 1, description thereof is omitted.

  The on-roof article attachment tool 1 includes a pair of clamping members 10 and 10, but the shape thereof is different from that of FIG. Further, the sandwiching members 10 and 10 are different in shape from each other.

  Each of the clamping members 10 extends substantially parallel to the pedestal portion 11 below the pedestal portion 11 below the pedestal portion 11 from the lower end thereof, and the pedestal portion 11 having the bolt insertion hole 11a, the leg portion 13 extending downward from the end portion thereof. And a sandwiching piece 14. About this clamping piece 14, it is the substantially same shape as the clamping piece 14 of the clamping member 10 shown in FIG.

  The ridges 11 and 11 and the legs 13 and 13 of any of the clamping members 10 and 10 are convex ribs that swell outward from the open end of the pedestals 11 and 11 to the lower end of the legs 13 and 13. 16 and 16 are formed. The rear surface side of the convex rib 16 is a concave portion, and one convex rib 16 is fitted to the rear side of the other convex rib 16 by stacking the pedestal portions 11 and 11 of the both clamping members 10 and 10 vertically. It has become. In addition, although the thing from which the shape of both the clamping members 10 and 10 mutually differs was illustrated, the same shape may be sufficient.

  Thus, the holding tool A of the article attachment tool 1 on the roof has a structure in which one of the pedestal portions 11 and 11 is arranged on the upper side and the other is arranged on the lower side to be superposed. Then, as shown in FIG. 7B, the fastening cover 20 is attached, and the three members are fastened with the bolts 31 and the nuts 32 as shown in FIG. .

  This roof article fixture 1 is also likely to be displaced or loosened only by the clamping members 10 and 10, but since it can be firmly fixed by adding the fastening cover 20, there is no displacement or looseness. Can be fixed on the roof in the state.

  Moreover, the on-roof article attachment tool 1 of the present embodiment can reduce the occurrence of deviation by fitting the convex rib 16 of one clamping member 10 and the concave portion on the back surface of the convex rib 16 of the other clamping member 10. However, it is also possible to use a holding member that does not have such a fitting structure and has a structure that only superposes the flat pedestals 11 and 11. Even such a clamping member is configured to use the tightening cover 20, and thus is less likely to be displaced.

  Moreover, the roof corresponding to the folded-plate roof 40 having a stacked continuous structure is designed by deforming such a vertically superposed clamping device A into a structure for fixing to the bolt body 47 as shown in FIGS. An upper article fixture can also be configured.
