In the clamping member 10, a bolt drop prevention portion (bending piece 12) is formed below the pedestal portion 11 and above the clamping piece 14.

  Next, each embodiment will be described. First, the configuration and structure of the on-roof article fixture 1 according to the embodiment shown in FIGS. 1 to 5 will be described.

  As shown in FIGS. 3 to 5, the on-roof article mounting tool 1 is a mounting tool that is mounted on a 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 roof article fixture 1 includes a pair of clamping members 10 and 10 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 in an L shape on the side edge that is opposite to the side edge provided with the leg portion 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 which the bent piece 12 is extended 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 31b of the bolt 31, but the edge of the bolt insertion hole 11a on the flat plate portion 11e side The part has a square shape.

  The bent piece 12 extends in an L shape below the edge of the pedestal portion 11, and the lateral piece 12 a extends substantially parallel to the flat plate portion 11 e of the pedestal portion 11. In addition, as shown in FIG. 5, the dimension of this horizontal piece 12a in the front view is a gap between the horizontal pieces 12a and 12a of the sandwiching members 10 and 10 when the roof-mounted article fixture 1 is mounted on the roof. As long as it can be. In other words, it suffices if the tips of the horizontal pieces 12a and 12a do not contact each other in the state of FIG. 5 and the bolt head 31c does not pass through the gap. Moreover, the dimension of the vertical piece 12b should just be a dimension which can accommodate the bolt head 31c of the volt | bolt 31 which fixes both the clamping members 10 and 10 and the horizontal piece 12a can avoid the contact with the goby part 45. FIG.

This bent piece 12 constitutes a bolt drop prevention part. Incidentally, the bent piece 12 is the same shape, when obtained by binding the two clamping members 10 and 10, the horizontal piece 12a is as long dimension enough to cover the bolt head 31c from below.

  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).

A sandwiching tool A is configured by combining two sandwiching members 10 and 10 having such a structure. Incidentally, as shown in FIG example, clamping member 10, 10 of a pair is Ru same shape der.

  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, as shown in FIG. 2, the bolt 31 is slid into the notch groove 11 b and attached to the bolt insertion hole 11 a in one of the holding members 10, The clamping tool A is formed by inserting the 11 notch grooves 11b and 11b into each other and superposing the pedestal portions 11 and 11 in an intersecting manner. As shown in FIG. 2, since the bent piece 12 is formed, the bolt 31 is unlikely to fall even when it is attached to one clamping member 10.

  In the state where the two clamping members 10 and 10 are combined and connected in this way, as shown in FIG. 3, the portions of the cutout grooves 11b and 11b can be used as a fulcrum in front view to open and close like scissors. .

  In this state, the flat plate portions 11e and 11e on which the bent pieces 12 and 12 of the pedestal portions 11 and 11 of the sandwiching members 10 and 10 are extended are both arranged on the lower side, and the two bolt insertion holes 11a are provided. The opening on the lower surface side of the overlapping bolt through hole formed by 11a is formed in a square shape so 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. .

  By screwing the bolt 31 and the nut 32, the pedestals 11 and 11 are superposed and fixed, and the both clamping members 10 and 10 are connected in a fixed state. As other members for connection, a flat washer 34 and a spring washer 35 are used. Further, as the bolt 31, it is desirable to use a root bolt as shown in the figure.

  The clamping tool A is fixed to the cross section 45 of the folded plate roof 40 in a state where the both clamping members 10 and 10 are connected and fixed in this manner. Hereinafter, this procedure will be described with reference to FIGS.

  First, as shown in FIG. 3, a pair of clamping members 10 and 10 are connected according to the procedure of FIG. 2 to form a clamping tool A, and the clamping tool A is opened and closed. In the holding tool A shown in FIG. 3, the bolt 31 is inserted into the overlapped bolt insertion holes 11a and 11a, but is not temporarily fixed by the nut 32, and the bolt 31 is bent downward and bent. The piece 12 is supported from below by the horizontal piece 12a.

  Thus, since the bolt 31 is supported by the bent piece 12 (bolt drop prevention portion), the bolt 31 does not fall out without using a plastic fall prevention plate or the like, and the operation can be facilitated. . In particular, it is convenient because the bolt 31 does not slide down between the pair of clamping members 10 and 10 and the bolt 31 until the state shown in FIG. Further, the subsequent nut 32 fixing operation does not have to worry about the bolt 31 dropping, and is easy to operate. Further, even if the bolt 31 and the both clamping members 10 and 10 are stored and packed in a state where the bolts 31 and the both clamping members 10 and 10 are temporarily coupled without stopping the nut 32, there is no possibility that the bolts 31 will be detached.

  After temporarily holding the clamping members 10 and 10 in this way, as shown in FIG. 4, the flat washer 34 and the spring washer 35 are attached to the shaft 31b of the bolt 31 protruding upward, and the nut 32 is screwed and temporarily fixed. .

  Next, as shown in FIG. 4, the holding tool A is placed on the top 42 of the folded plate roof 40 with both the holding pieces 14, 14 on both sides of the holding piece 45 with the holding pieces 14, 14 open. Place it so that it is more pinched.

  In this state, the bolt 31 is pulled upward, the root corner portion 31a is fitted into the square opening of the bolt through hole, and the nut 32 is tightened in a state where the bolt 31 is prevented from rotating. If it does so, it will superpose | polymerize so that both pedestal parts 11 and 11 of both the clamping members 10 and 10 which were fulcrum-connected may approach in parallel, At the same time, both leg parts 13 and 13 will close and the space | interval between clamping pieces 14 and 14 will narrow. 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 tightening with the nut 32, a tool such as a finger or a screwdriver is inserted into the space surrounded by the pedestals 11 and 11 and the bent pieces 12 and 12 so that the root 31a is not removed from the opening. It is desirable to support the bolt head 31c from below.

  By screwing the nut 32, both the leg portions 13 and 13 are further tightened, and the lateral outer surfaces of the pressing portions 14a and 14a of the holding pieces 14 and 14 are further pressed against the outer surface of the standing base portion 45a of the goby portion 45. It is done.

  Then, by firmly screwing the nut 32 to the bolt 31, the overlapped base parts 11 and 11 are firmly overlapped and fixed in the vertical direction, and at the same time, both the sandwiching pieces 14 and 14 have their tips at the ends. The upright base 45a of the portion 45 is fixed in a state of being pressed from both sides (see FIG. 5).

  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 base part 11.
