  Reference numeral 3 denotes a hanger such as a nylon sling belt or wire rope, which is hung and hung from the hung material 1 in a ring shape, and uses two hanger 3 and 3. Thus, both ends of the suspended material 1 stacked vertically are hugged and suspended.

  Reference numeral 5 denotes a slip prevention tool for preventing the suspension tool 3 from shifting with respect to the suspended material 1, and the displacement preventing tool 5 is a side surface 1 a of the suspended material 1. A displacement prevention tool body 6 made of a rectangular plate-like member, a rod-shaped protrusion 7 inserted into the hole 2 provided at the center of the back surface 6a of the displacement prevention tool body 6, and the displacement. A rectangular plate-shaped protruding piece 8 that is provided between the upper and lower suspended materials 1 that are provided adjacent to each other and provided on the upper side 6 b of the prevention device main body 6, and the surface 6 c of the deviation prevention device main body 6. It consists of a locking part 9 that locks the hanging tool 3 to the shift prevention tool 5.

  The protrusion 8 is mainly for preventing rotation of the anti-slip tool body 6 when the anti-slip tool body 6 is mounted on the suspended material 1. The protrusion 8 may be provided at an arbitrary position on the back surface 6a of the main body 6, but the protrusion 8 is provided at a position shifted to one end side or the other end side from the center of the upper side 6b of the misalignment prevention tool main body 6. When the hanging tool 3 is locked to the portion 9, it is preferable that the protruding piece 8 is shifted to the one end side or the other end side from the hanging tool 3.

  This is because if the protrusion 7 is simply inserted into the hole 2 of the suspended material 1, it may come out of the hole 2 and the displacement prevention tool 5 may come off the suspended material 1. The protrusion 7 and the protruding piece 8 are provided, and in particular, by providing the protruding piece 8 at a position shifted to one end side or the other end side, the slip prevention tool 5 is easily detached from the suspended material 1. Can be prevented.

  Further, even when the displacement prevention tool 5 receives a rotational force from the suspension tool 3, the protrusion 8 is provided at a position shifted to one end side or the other end side. The range in which the tool body 6 rotates is narrowed.

  The protruding piece 8 may be provided on the lower side 6d instead of being provided on the upper side 6b of the misalignment prevention main body 6. However, as will be described later, the suspended material 1 whose lower side is curved in a convex shape is provided. In the case of suspending, the slip prevention tool 5 having the projecting piece 8 provided on the upper side 6b of the slip prevention tool main body 6 and at a position shifted to the center side of the suspended material from the center of the upper side 6b is covered. By attaching the suspension member 1 to the suspension member 1, the projecting piece 8 receives the force from the suspension member 3, and the displacement prevention member 5 is firmly fixed to the suspension member 1.

  In addition, although it is preferable that the said protrusion piece 8 is a plate-shaped thing in order to insert between the suspended materials 1 adjacent to the upper and lower sides, it may be rod-shaped.

  The locking portion 9 is composed of one and the other bent portions 9a and 9a which are bent at an acute angle in a direction facing each other from the both ends 6e and 6e of the anti-slip tool body 6 to the surface 6c side. By inserting the suspending tool 3 between the one and the other bent portions 9a, 9a, the suspending tool 3 is locked with respect to the deviation preventing tool body 6.

  The insertion port 4 between the bent portions 9a, 9a of the locking tool 9 may be larger than the width of the hanging tool 3 so that the hanging tool 3 can be easily inserted. The inside of the locking tool 9 may have a play in which the inserted hanging tool 3 can move in the left-right direction.

  In addition, a bent portion bent in a right angle direction is formed on the surface 6c side from both end portions 6e, 6e of the anti-slip tool main body 6, and the hanging tool 3 is inserted between one and the other bent portions. The suspension tool 3 may be locked to the misalignment prevention tool body 6. However, when a strong force is applied to the suspension tool 3 when the suspended material 1 is suspended, the suspension tool 3 is suspended. The lowering tool 3 may get over the bent part formed in the perpendicular direction.

  Therefore, it is preferable to form the bent portions 9a, 9a at an acute angle, so that even if a strong force is applied to the hanging tool 3, the hanging tool 3 enters the bent portion and does not come off. It becomes like this.

  Moreover, even if the tension | tensile_strength is not applied to the said hanging tool 3, the said hanging tool 3 becomes difficult to remove | deviate because the said bending part 9a is formed in the acute angle.

  In addition, the said bending part 9a may be rod-shaped instead of plate shape.

  In addition, as the said latching | locking part 9, instead of providing the said one and other bending parts 9a, an annular part is provided in the surface of the said slip prevention tool main body (not shown), and the suspending tool 3 is set in this annular part. It may be inserted and locked.

  Moreover, you may make it fix the said hanging tool 3 to the said slip prevention tool main body 6 by fixing means (not shown), such as a fastener.

  Moreover, instead of forming the displacement preventing tool main body 6 and the bent portion 9a with plate-like members, a plurality of rod-like members bent at both ends at acute angles may be connected in parallel.

  Since the shift prevention tool of the hanging tool of the present invention has the above-described configuration, one and the other hanging parts that are respectively ring-shaped at both ends of the suspended material 1 that are placed on the ground and stacked in the vertical direction. The tools 3 and 3 are inserted, and the protrusions 7 and 7 of the one and the other anti-slip tool 5 are inserted into the holes 2 of the suspended material 1 at positions corresponding to the one and the other hanging tools 3 and 3. , And the protrusions 8 are inserted between the suspended members 1 and 1 adjacent to each other in the vertical direction so that the shift preventing device 5 is mounted on the suspended material 1 and the engagement member The said suspending tool 3 is inserted between the bending parts 9a and 9a of the stop part 9. FIG.

  Thereby, the said suspending tool 3 is latched by the said shift prevention tool 5, and the said to-be-suspended material 1 is suspended by the said suspending tool 3. FIG.

  In addition, although it is preferable to attach the shift prevention tool 5 to the front side surface and the back side surface of the suspended material 1 with respect to each hanging tool 3, it should be attached only to either the front side surface or the back side surface. May be.

  Moreover, although it is preferable to mount | wear the said anti-slipping tool 5 to the hole 2 of the suspended material 1 of the lowest step, you may mount | wear to the hole 2 of the suspended material 1 of another stage.

  Moreover, as shown in FIG. 1, when the suspended material 1 whose lower side is curved in a convex shape is suspended, a force is applied to the suspension tool 3 on the center side of the suspended material 1, thereby In FIG. 1, the left misalignment prevention tool 3 tries to rotate clockwise, and the right misalignment prevention tool 3 tries to rotate counterclockwise. For this reason, each of the anti-slip devices 5 having the protrusions 8 provided on the upper side 6b of the above-described anti-slip device body 6 and at a position shifted from the center of the upper side 6b toward the center of the material to be suspended is respectively provided. As a result, the projecting piece 8 receives the force from the hanging tool 3, and the displacement preventing tool 5 is firmly fixed to the suspended material 1.

  It should be noted that, depending on the shape of the suspended material and the mounting position of the shift prevention tool, the shift prevention tool 5 having the protruding piece 8 shifted in either direction is used in consideration of the force related to the shift prevention tool. Also good.

  Further, the number of the suspended material may be one. In this case, the protruding piece 8 is positioned on the upper surface or the lower surface of the suspended material 1.

  According to the shift prevention tool of the hanging tool of the present invention, the protrusion 7 of the shift prevention tool 5 is inserted using the hole 2 for bolt insertion or the like formed in the suspended material 1 to prevent the shift prevention tool 5. Is attached to the suspended material 1, so that the suspension tool 5 can be prevented from being displaced with respect to the suspended material 1 with a simple configuration.

  In addition, by providing the protruding portion 7 and the protruding piece 8, it is difficult for the deviation preventing tool 5 to be detached from the suspended material 1.

  Moreover, the said protrusion 8 does not rotate the said slip prevention tool 5, and a suspending tool will not come off from a slip prevention tool.

  In addition, since the hanging tool 3 is locked by the acute-angled bent portion, the hanging tool 3 is unlikely to come off from the deviation preventing tool 5.

  Further, conventionally, when suspending a suspended material with two suspension tools, the tension is applied to the suspended device that holds the suspended material until the stability of the suspended material is confirmed. In order to prevent them from slipping, it was necessary for two workers to hold the hanging tool from both sides of the material to be suspended, and there was a risk that the worker would be caught. 5 is attached to the suspended material 1 and the hanging tool 3 is locked to the shift preventing tool 5, so that the hanging tool 3 is not displaced and before the tension is applied to the hanging tool 3, the worker Can release his hand from the hanger 3.
