Definitions

  • the present invention relates to a reinforcing bar locking device for fixing a reinforcing bar inserted into a plurality of arrayed blocks while applying a tensile force to the reinforcing bar, which can be locked with the reinforcing bar exposed from an end face of the blocks.
  • a reinforcing bar inserted into the blocks so as to run through hollow portions or the like in the blocks is often fixed while applying a tensile force to the reinforcing bar in order to increase the bonding force between the blocks.
  • the reinforcing bar is fixed by mounting a member having a function of a washer which is larger than the internal diameter of the hollow portions or the like and a nut on the end portion of the reinforcing bar exposed from the end face of the blocks and by tightening the nut (see Patent Document 1, for example).
  • Patent Document 1 Japanese Patent Publication No. S34-3622
  • Patent Document 1 by screwing and tightening a nut onto an end portion of a reinforcing bar protruding from an end face of a block which is positioned uppermost on a group of stacked blocks, the group of blocks can be fixed while applying a tensile force to the reinforcing bar.
  • the end portion of the reinforcing bar exposed from the end face of the block is long, the nut screwed onto the end portion of the reinforcing bar needs to be turned many times until the nut reaches the desired position on the end face of the block. Therefore, the operation of mounting the nut on the reinforcing bar is troublesome and takes a long time.
  • An object of the present invention is to provide a reinforcing bar locking device which can be easily locked at a position relatively far from an end portion of a reinforcing bar and apply a relatively strong locking force to the reinforcing bar.
  • a reinforcing bar locking device comprises a body member having a through hole in which a reinforcing bar is insertable; a plurality of fitting members which are fitted between the reinforcing bar inserted into the through hole and an inner peripheral surface of the through hole, the inner peripheral surface of the through hole having a funnel shape whose diameter is reduced in a direction of a center axis; an engaging section which engages with the reinforcing bar formed on an inner peripheral surface of the fitting members; and a conical surface which has surface contact with the inner peripheral surface of the body member formed on at least a part of an outer peripheral surface of the fitting members.
  • the reinforcing bar locking device can be locked at a desired position on a reinforcing bar in the following process.
  • a body member is mounted so that an end portion of a reinforcing bar protruding from an end face of a block penetrates from a smaller opening to a larger opening of a through hole of the body member.
  • a tensile force is applied to the reinforcing bar.
  • a plurality of fitting members are fitted between the reinforcing bar and an inner peripheral surface of the through hole while an engaging section of the fitting members is engaged with the reinforcing bar.
  • the reinforcing bar contracts in a direction of a center axis so that the plurality of fitting members are pulled in a direction toward the reduced diameter of the through hole while engaging with the reinforcing bar, and a conical surface on an outer peripheral surface of the fitting members is brought into surface contact with the inner peripheral surface of the through hole of the body member and locked.
  • the reinforcing bar locking device is locked at the desired position of the reinforcing bar (on the end face of the block, for example) so as not to move.
  • the body member mounted from the end portion of the reinforcing bar can be moved to the end face of the block without turning the body member. Therefore, the body member can be easily locked even at a position far from the end portion of the reinforcing bar. Furthermore, the reinforcing bar, the fitting members, and the body member can be locked in an integrated manner with the contracting force of the reinforcing bar after releasing the tensile force, which exhibits a relatively strong locking force applied to the reinforcing bar. It is also possible to interpose a washer member having a through hole for the reinforcing bar between the body member of the reinforcing bar locking device of the present invention and the end face of the block.
  • a female screw thread part which is screwed onto a male screw part formed on an outer peripheral surface of the reinforcing bar may be provided on the inner peripheral surface of the fitting member.
  • the fitting member may be further provided with a slit which is opened in the direction of the center axis of the through hole.
  • the body member may be provided with, on an outer periphery thereof, at least a pair of flat parts arranged in parallel with each other on opposite sides of the center axis of the through hole.
  • a tool such as a wrench can engage with the flat parts of the body member to turn the body member.
  • the reinforcing bar locking device locked on the reinforcing bar can be tightened or loosened using a wrench or the like.
  • the present invention can provide a reinforcing bar locking device which can be easily locked at a position relatively far from an end portion of a reinforcing bar and apply a strong locking force to the reinforcing bar.

  • an inserting section 11 c which has a substantially cylindrical shape and a flange section 11 d which has a larger external diameter than the inserting section 11 c are provided.
  • the two fitting members 12 are positioned to oppose each other so that an outer appearance of the fitting members 12 forms an inverted, substantially truncated conical shape, and are inserted into the through hole 11 a of the body member 11 .
  • the female screw thread part 12 a on the inner peripheral surface of the fitting members 12 is screwed onto a male screw part 13 a formed on an outer peripheral surface of the reinforcing member 13 , thereby clamping the reinforcing bar 13 .
  • a slit 12 c is formed in the direction along the center axis C of the through hole 11 a .
  • the slit 12 c is opened from an upper end toward a lower end of the fitting member 12 .
  • a length of the slit 12 c is approximately 65 to 75% of a length of the fitting member 12 in the direction of the center axis C but is not limited to this length.
  • FIGS. 10 to 12 illustrate an example of construction where the reinforcing bar 13 is inserted into a hollow part 14 a of stacked concrete blocks 14 and fixed while applying a tensile force to the reinforcing bar 13 .
  • a plate member 15 having a function of a washer is placed on an end face 14 b of the block 14 positioned uppermost.
  • the plate member 15 has a locking hole 15 a which has a smaller diameter than the hollow part 14 a and allows the reinforcing bar 13 to pass therethrough.
  • An end portion 13 b of the reinforcing bar 13 inserted into the hollow part 14 a projects from the locking hole 15 a of the plate member 15 .
  • a lower end portion (not shown) of the reinforcing bar 13 is fixed to an end face of a block positioned lowermost (not shown).
  • the body member 11 is mounted so that the end portion 13 b of the reinforcing bar 13 passes through the through hole 11 a of the body member 11 from a smaller opening 11 f to a larger opening 11 g . Then, the body member 11 is moved along the reinforcing bar 13 up to the plate member 15 on the end face 14 b of the block 14 , and the inserting section 11 c of the body member 11 is inserted into the locking hole 15 a of the plate member 15 , resulting in the state where the flange section 11 d protrudes from an upper face of the plate member 15 .
  • a conventional hydraulic jack (not shown) is set on a side of the end portion 13 b of the reinforcing bar 13 to apply a tensile force T to the reinforcing bar 13 .
  • the two fitting members 12 are fit between the reinforcing bar 13 and the inner peripheral surface 11 b of the through hole 11 a of the body member 11 , and clamp the reinforcing bar 13 .
  • the female screw thread part 12 a which is an engaging section of the fitting member 12 (see FIG. 4 ) is screwed onto the male screw part 13 a on the outer peripheral surface of the reinforcing bar 13 .
  • an upper end portion of the fitting member 12 in the reinforcing bar locking device 10 is rendered somewhat protruding from the larger opening 11 g of the body member 11 .
  • the tensile force T applied to the reinforcing bar 13 is released.
  • the plurality of fitting members 12 are pulled in a direction toward the reduced diameter of the through hole 11 a of the body member 11 as shown in FIG. 12 while the plurality of fitting members 12 are maintained to engage with the reinforcing bar 13 , and the outer peripheral surface 12 b (conical surface) of the fitting members 12 is brought into surface contact with the inner peripheral surface 11 b of the through hole 11 a of the body member 11 and locked thereon.

  • the body member 11 mounted from the end portion 13 b of the reinforcing bar 13 can be moved up to the end face 14 b of the block 14 without turning the body member 11 at all. Therefore, the body member 11 can be easily locked at a position relatively far from the end portion 13 b of the reinforcing bar 13 . Moreover, with the contracting force of the reinforcing bar 13 after releasing the tensile force T, the reinforcing bar 13 , the fitting member 12 , and the body member 11 are locked in an integrated manner, which exhibits a strong locking force applied to the reinforcing bar 13 .
  • the female screw thread part 12 a which engages with the male screw part 13 a formed on the outer peripheral surface of the reinforcing bar 13 is formed on the inner peripheral surface of the fitting member 12 as the engaging section. Therefore, the fitting member 12 and the reinforcing bar 13 can be firmly engaged with each other, applying a strong locking force to the reinforcing bar 13 . Furthermore, as shown in FIGS. 7 to 9 and other figures, the slit 12 c is opened in each of the pair of fitting members 12 .
  • the fitting members 12 themselves are deformable so as to reduce their diameter due to a surface pressure applied by the inner peripheral surface 11 b of the through hole 11 a . Accordingly, a clamping action of the fitting members 12 exerted onto the reinforcing bar 13 is increased, thereby exhibiting an extremely strong locking force to the reinforcing bar 13 .
  • reinforcing bar locking devices 20 and 30 shown in FIGS. 13 and 14 the members having the same functions and effects as those of the members of the above-described reinforcing bar locking device 10 bear the same reference numerals as in FIGS. 1 to 12 , and the explanation thereof is omitted.
  • the reinforcing bar locking device 20 shown in FIG. 13 has a pair of flat parts 21 a formed on an outer periphery of a body member 21 .
  • the flat parts 21 a are arranged in parallel with each other on opposite sides of a center axis C of a through hole 11 a .
