A mounting device according to claim 2 is a hanging device for hanging a rope on at least one of the first fixing means, the second fixing means and the third fixing means of the mounting device according to claim 1. Is provided.

  The fixture according to claim 1 includes two clamping means.

  Therefore, since this attachment can be attached to, for example, H steel by using two clamping means, conventional attachment to the H steel is a parent of a structure using one clamping means. Compared to the leash attachment tool, it is less likely to fall off the H steel after being attached to the H steel.

  In addition, since this attachment is provided so that the openings of each of the pair of clamp means are opposed to each other, for example, this attachment uses two clamp means when attaching to H steel. Thus, the H steel flange can be attached from both end sides of the H steel flange.

  As a result, for example, after the attachment tool is attached to the H steel, for example, some external force is applied to the one clamp means of the pair of clamp means. When acting from the direction of the column of the clamp body portion to the opening portion, such an external force is applied to the other clamp means of the pair of clamp means in a substantially U-shaped clamp body of katakana characters. Since it comes to work in the direction of the pillar from the direction of the opening of the part, this attachment is difficult to drop off from the H steel after being attached to the H steel, for example.

  That is, this attachment is superior to the conventional master rope attachment because, for example, it is difficult to drop off from the H steel after being attached to the H steel.

Further, in this fixture, the member having a predetermined length is a member provided to be stretchable and the pair of clamping means are provided so that the interval can be changed. Even if the widths of the steel plates are different, by changing the length of the members provided to be stretchable, the clamps are used by sandwiching the H steel flange from both ends of the H steel flange.

The first pipe member is externally sandwiched, and one clamp means of the pair of clamp means is attached to the second pipe member, and the other clamp means of the pair of clamp means is attached to the third pipe member. It is attached.

  That is, since this attachment is provided with the openings of each of the pair of clamping means so as to face each other, for example, this attachment uses two clamping means when attaching to H steel. Thus, the H steel flange can be attached from both end sides of the H steel flange.

  As a result, for example, after the attachment tool is attached to the H steel, for example, some external force is applied to the one clamp means of the pair of clamp means. When acting from the direction of the column of the clamp body portion to the opening portion, such an external force is applied to the other clamp means of the pair of clamp means in a substantially U-shaped clamp body of katakana characters. Since it comes to work in the direction of the pillar from the direction of the opening of the part, this attachment is difficult to drop off from the H steel after being attached to the H steel, for example.

  That is, this attachment is superior to the conventional master rope attachment because, for example, it is difficult to drop off from the H steel after being attached to the H steel.

  In addition, the mounting tool is a member of the first pipe member, the second pipe member, and the third pipe member that constitutes a member that is provided to be stretchable. Since each pair of clamping means is provided so that the openings face each other, the first pipe member, the second pipe member, and the second pipe member can be provided even if the H steel flanges have different widths. Two clamp means are used by sandwiching the H-steel flange from both ends of the H-steel flange by changing the length of the three pipe members provided in a stretchable manner. Thus, the H steel flange can be attached from both end sides of the H steel flange.

Further, in this attachment , the first pipe member, the second pipe member, and the third pipe member are arranged so that the long holes provided in each of the pair of gap adjustment members overlap each other. A first fixing means that is accommodated in the pipe member and is provided at a center position in the longitudinal direction of the first pipe member or substantially at the center position so as to pass through each elongated hole of the pair of interval adjusting members; and The total length of the long holes provided in each of the pair of interval adjusting members is set so that the second pipe member and the third pipe member are sandwiched between the first pipe members. The first pipe member, the first pipe member, the second pipe member, and the third pipe member, which are provided so as to be sheathed, are provided with the first pipe member. The overlapping portion of the member and the second pipe member and Is the length of the overlapping portion P2 of the first pipe member and the third pipe member are not lost.

  That is, this attachment is provided in each of the pair of interval adjusting members, more specifically, the total length of the long holes provided in each of the pair of interval adjusting members. When the first fixing means has a cylindrical shape from the total length of the long holes, the first pipe member, the second pipe member, and the third pipe up to a length obtained by subtracting the diameter thereof. It is possible to extend the length of a member that is configured to be extendable and configured by the pipe member.

  And in this fixture, it is provided in each of a pair of space | interval adjustment members, and more specifically, the total length of the length of the long hole provided in each of a pair of space | interval adjustment member, and more specifically, When the first fixing means has a cylindrical shape from the total length of the long holes, the length obtained by subtracting the diameter is set to each of the second pipe member and the third pipe member. The first pipe member, the second pipe member, and the third pipe member, which are provided so as to cover the first pipe member with the first pipe member interposed therebetween, are extendable and retractable The members provided in the first and second pipe members have such length that the overlapping portion between the first pipe member and the second pipe member and the overlapping portion between the first pipe member and the third pipe member are not lost.

  The fixture 1 is assembled by the above process.

  The assembly process of the mounting tool 1 described above is merely used for explaining the mounting tool according to the present invention, and the assembly process of the mounting tool according to the present invention is limited to the above-described assembly process. There is nothing.

  Next, a method for using the fixture 1 shown in FIG. 1 will be schematically described.

  FIG. 4 is a side view schematically showing an example of use of the fixture 1 shown in FIG.

  When a master rope for preventing an operator from falling down is to be handed over to a high work place such as a construction site, first, the member 2 provided in a telescopic manner of the fixture 1 is vertically or substantially vertical. Of the pair of flanges 21 and 22 provided so as to sandwich the web 20 of H steel 19 provided in the direction, according to the width W21 of the flange 21 on the side to which the fixture 1 is attached, it is appropriately expanded and contracted, The distance between the opening 5a of the clamp means 5 provided in the fixture 1 and the opening 6a of the clamp means 6 provided in the fixture 1 is set in the pair of flanges 21 and 22 of H steel 19, The width is set to be slightly wider than the width W21 of the flange 21 on the side where the fixture 1 is attached.

  Next, the flange half 21a of the flange 21 of the H steel 19 is inserted into the recess of the clamp body 10 having an approximately U-shape of the katakana character from the opening 5a of the clamp means 5 provided in the fixture 1. A screw 11 screwed into one of the plate-like members 10a of the plate-like members 10a, 10b arranged opposite to the clamp main body portion 10; and a plate-like member 10a arranged opposite to the clamp main body portion 10; The clamp means 5 of the fixture 1 is attached to the H steel 19 by screwing in the direction of the other plate-like member 10b of 10b.

  Next, the member 1 provided in a freely stretchable manner on the fixture 1 is appropriately shrunk so that the fixture 1 in the pair of flanges 21 and 22 provided so as to sandwich the web 20 of the H steel 19 is inserted. The flange half 21b of the flange 21 on the attachment side is received from the opening 6a of the clamp means 6 provided in the fixture 1 into the recess of the clamp body 12 having a substantially U-shape of the Katakana character, A screw 13 screwed into one plate-like member 12a of the plate-like members 12a, 12b arranged to face each other of the clamp main body 12 is connected to the other of the plate-like members 12a, 12b arranged to face each other of the clamp main body portion 12. The clamp means 6 of the fixture 1 is attached to the H steel 19 by being screwed in the direction of the plate-like member 12b.

  The fixture 1 includes two clamping means 5 and 6.

  Therefore, since this attachment 1 can be attached to the H steel 19 using, for example, two clamping means, the conventional attachment to the H steel 19 is performed using one clamping means. Compared to the structure of the main rope attachment (the conventional parent rope attachment (master rope support) 101 shown in FIG. 12) and the conventional parent rope attachment (attachment jig for the kite fall prevention tool) 201 shown in FIG. After being attached to the H steel 19, it is difficult to drop off from the H steel 19.

  And since this attachment 1 is provided so that each opening part 5a, 6a of a pair of clamp means 5 and 6 may mutually oppose, when this attachment 1 is attached to the H steel 19, for example In addition, the two clamping means 5 and 6 can be used to sandwich the flange 21 of the H steel 19 from both ends of the flange 21 of the H steel 19.

  As a result, for example, after the attachment 1 is attached to the H steel 19, for example, some external force is applied to one of the clamp means 5 of the pair of clamp means 5, 6. When acting in the direction of the opening 5a from the direction of the column portion 10c of the generally U-shaped clamp body portion 10 of the katakana character, such an external force is applied to the other clamp means 6 of the pair of clamp means 5 and 6.

  Further, for example, after the attachment tool 1 is attached to the H steel 19, for example, some external force is applied to the other clamp means 6 of the pair of clamp means 5 and 6 in the katakana name. When acting in the direction of the opening 6a from the column portion 12c direction of the substantially U-shaped clamp body portion 12 of the character, such an external force is applied to one clamp means 5 of the pair of clamp means 5 and 6. Since this works from the direction of the opening 5a of the clamp body portion 10 having a substantially U-shaped katakana character to the direction of the column portion 10c, the attachment 1 is attached to the H steel 19, for example, It is difficult to drop off the steel 19.

  That is, the attachment 1 is superior in safety to the conventional master rope attachment because, for example, the attachment 1 is less likely to fall off the H steel 19 after being attached to the H steel 19.

  In addition, the fixture 1 includes a pair of clamp means 5 and 6 so that the opening 2a and 6a can be changed so that the member 2 provided in a telescopic manner can be spaced apart by a predetermined distance. Are provided so as to face each other.

  Therefore, even if the width W21 of the flange 21 of the H steel 19 is different, the fixture 1 can be changed from the both ends of the flange 21 of the H steel 19 by changing the length of the member 2 provided to be stretchable. Mounting can be performed by sandwiching the flange 21 of the H steel 19 from both ends of the flange 21 of the H steel 19 by sandwiching the flange 21 of the H steel 19 using the two clamping means 5 and 6. .

The fitting 1 is attached to the pipe member 9, and the fitting 1 is provided with the openings 5a and 6a of the pair of clamping means 5 and 6 so as to face each other. Is attached to the H steel 19 by using the two clamping means 5 and 6 so as to sandwich the flange 21 of the H steel 19 from both ends of the flange 21 of the H steel 19.

  As a result, for example, after the attachment 1 is attached to the H steel 19, for example, some external force is applied to one of the clamp means 5 of the pair of clamp means 5, 6. When acting in the direction of the opening 5a from the columnar direction 10c of the substantially U-shaped clamp main body 10 of the katakana character, such an external force is applied to the other clamping means 6 of the pair of clamping means 5,6. In order to work from the direction of the opening 6a of the clamp body portion 12 of the substantially U-shaped clamp body portion 12 of Katakana characters, this attachment 1 is attached to the H steel 19, for example, It is difficult to drop off from H steel 19.
