Description

  The present invention relates to a bar arrangement method of a interdigital reinforcing bar unit having a configuration in which a plurality of reinforcing bar materials are connected in an interdigital shape, and a reinforcing bar connecting jig used therefor.

  2. Description of the Related Art Conventionally, in order to reduce the labor of reinforcing bar arrangement work at a construction site and improve the construction efficiency, interdigital reinforcing bar units having a configuration in which a plurality of reinforcing bar materials are connected in an interdigital manner have been provided. The interdigital reinforcing bar unit consists of a plurality of reinforcing bar members extending in one direction connected by a string or strip-like member (strip material) such as a connecting string so as to have a predetermined bar spacing. According to the reinforcing bar unit, the interdigital reinforcing bar unit is manufactured in advance at the processing site or the processing yard in the site, and this interdigital reinforcing bar unit is transported to the construction site and arranged, thereby transporting and lifting the reinforcing bar material. Construction efficiency can be improved by reducing the labor of bar arrangement work (see, for example, Patent Documents 1 to 5).

In the conventional bar arrangement method using the interdigital reinforcing bar unit as described above, in order to prevent disturbance of the bar arrangement during concrete placement, the orthogonal reinforcing bar members are bound together with a tie wire in the same manner as normal bar arrangement. We are uniting. For example, in the case of a floor bar that arranges a plurality of reinforcing bars in a grid pattern, first, the first interdigital reinforcing bar unit (lower end main bar) in the short side direction is deployed at the construction site, and then the first deployed The second interdigital reinforcing bar unit (lower end reinforcing bar) in the long side direction is expanded perpendicular to the interdigital reinforcing bar unit. Thereafter, the reinforcing bars of the first and second interdigital reinforcing bar units are bundled by the operator manually to stabilize the bar arrangement state of the lower bars. Next, a third interdigital reinforcing bar unit (top end reinforcing bar) in the long side direction is developed on the lower bar that has been arranged, and then perpendicular to the third interdigital reinforcing bar unit in the short side direction. The fourth interdigital reinforcing bar unit (upper main bar) is developed. Thereafter, the reinforcing bars of the third and fourth interdigital bar units are orthogonally bound together by an operator to stabilize the upper bar arrangement state.

  Next, the bar arrangement method of the interstitial reinforcing bar units 5 and 6 processed using the reinforcing bar connecting jigs 1 having the above-described configuration will be described.

  First, as shown in FIG. 3, a step of arranging a plurality of first reinforcing bars (reinforcing bars in the main reinforcing bars) 9 on the construction place X such as a slab formwork is performed. Specifically, spacers 15 such as bar-type spacers are arranged at predetermined intervals on the construction site X, and the reinforcing bars 9 are extended in the short side direction (main bar direction) on the spacers 15.

Specifically, as shown in FIGS. 1 and 4, the reinforcing bar connecting jig 1 is arranged in a direction orthogonal to the reinforcing bar members 9, and the cylindrical portions 31 of the mounting members 3 attached to the reinforcing bar connecting jig 1. .. Are fitted into the reinforcing bars 9. At this time, as shown in FIG. 5, the attachment member 3 is fitted from the lower side of the reinforcing bar material 9 with the opening 31 a of the mounting member 3 facing upward so that the strip material 2 passes through the lower side of the reinforcing bar material 9. Further, as shown in FIG. 4, the reinforcing bar connecting jigs 1 and 1 are attached to at least both ends of the reinforcing bar members 9, respectively, and the reinforcing bar connecting jigs 1 are also attached to the centers of the reinforcing bar members 9 as necessary.

  Next, as shown in FIG. 6, after the interleaved reinforcing bar unit 5 formed by connecting a plurality of reinforcing bar materials 9 in an interdigital manner is developed, the tension means 4 provided in each reinforcing bar connecting jig 1. ..., a step of introducing a tension to each of the strips 2 to put each of the strips 2 into a tension state is performed. Specifically, as shown in FIGS. 6 and 7, first, a reinforcing bar member in which a worker is arranged at the end by using a reinforcing bar 7 having a configuration in which a hook is attached to the end of a rod-shaped handle. 9 'is pulled to the side, and the interdigital reinforcing bar unit 5 formed in a gathered state is spread. Then, alignment is performed so that the interleaved reinforcing bar unit 5 that is expanded (expanded) is disposed at a predetermined position. At this time, the spacers 15 are arranged at an appropriate interval at the construction site X so that the spacers 15 are arranged under the developed interdigital reinforcing bar unit 6. Subsequently, as shown in FIGS. 1 and 6, the hook 46 a on the base end side of the first hooking member 41 is hooked to the end of the ring-shaped strip 2, and The hook 45a on the distal end side is hooked on the beam line 11 that can take a reaction force. In addition, the hook 42b of the second hooking member 42 is hooked on the beam 12 that is opposite the beam 11 and can be reacted, and the reinforcing bar connecting jig 1 is attached to the beam bars on both sides. 11 and 12 are in a state of being bridged. Thereafter, the strip material 2 is pulled by the turn buckle mechanism 43 of the first hooking member 41, and tension is introduced into the strip material 2. That is, by rotating the body frame 44 of the turnbuckle mechanism 43 and moving the screw rods 45 and 46 closer to each other, the overall length of the reinforcing bar connecting jig 1 is shortened, thereby introducing tension into the strip 2. . The above-described operation is performed for each reinforcing bar connecting jig 1.

  Next, as shown in FIG. 8, a plurality of second reinforcing bars that are orthogonal to the first reinforcing bars 9 on the interleaved reinforcing bar unit 5 (first reinforcing bars 9) in an unfolded state. A step of arranging (reinforcing bars in the direction of the reinforcing bars) 10. Specifically, on the interstitial reinforcing bar unit 5, as in the case of the first reinforcing bar material 9 described above, an appropriate interval is provided so that the reinforcing bar members 10 do not overlap with each other, and the second reinforcing bar material. 10... Are extended in the long side direction (distribution direction).

  Next, as shown in FIG. 9, a plurality of reinforcing bar connecting jigs 1 are respectively attached to the arranged plurality of reinforcing bars 10 to connect the plurality of reinforcing bars 10 in a comb shape. Specifically, as shown in FIGS. 1 and 9, the reinforcing bar connecting jig 1 is arranged in a direction orthogonal to the reinforcing bar members 10 as in the case of the first reinforcing bar members 9 described above, and this reinforcing bar connection is performed. The cylindrical portions 31 of the mounting members 3 attached to the jig 1 are fitted into the reinforcing bars 10. At this time, as shown in FIG. 10, the attachment members 3 are fitted from above the reinforcing bars 10 with the openings 31a of the attachment members 3 facing downward so that the strip 2 passes above the reinforcing bars 10. To do. Further, as shown in FIG. 9, similarly to the case of the first reinforcing bar material 9 described above, the reinforcing bar connecting jigs 1 and 1 are respectively attached to at least both ends of the reinforcing bar material 10. Attach the rebar connecting jig 1 to the center of the ....

  Next, as shown in FIG. 11, after the interleaved reinforcing bar unit 6 formed by connecting a plurality of reinforcing bar materials 10 in an interdigital manner is developed, the tension means 4 provided in each reinforcing bar connecting jig 1. ..., a step of introducing a tension to each of the strips 2 to put each of the strips 2 into a tension state is performed. Specifically, as in the case of the first reinforcing bar material 9 described above, first, as shown in FIGS. 7 and 11, the reinforcing bar with the operator placed at the extreme end using the reinforcing bar tension tool 7. The material 10 'is pulled to the side, and the interleaved reinforcing bar unit 6 formed in a gathered state is expanded, and alignment is performed so that the expanded interdigital reinforcing bar unit 6 is arranged at a predetermined position. Subsequently, as shown in FIGS. 1 and 11, the hook 46 a on the proximal end side of the first hooking member 41 is hooked to the end of the ring-shaped strip 2, and The hook 45a on the distal end side is hooked on the beam line 13 that can take a reaction force. Further, the hook 42b of the second hooking member 42 is hooked to the beam bar 14 that is opposite to the beam bar 13 and capable of receiving a reaction force, and the reinforcing bar connecting jig 1 is attached to the beam bars on both sides. 13 and 14 are bridged. Thereafter, the strip material 2 is pulled by the turn buckle mechanism 43 of the first hooking member 41, and tension is introduced into the strip material 2.

  When the slab reinforcement is a single reinforcement, the slab reinforcement arrangement is completed, and the process moves to the concrete placing process. On the other hand, when the slab reinforcement is double reinforcement, the upper reinforcement is subjected to the same process as the above-described arrangement process, and thereafter, the process moves to the concrete placing process.

  According to the bar arrangement method of the interdigital reinforcing bar units 5 and 6 and the reinforcing bar connecting jig 1 used for the interdigital reinforcing bar units 5 and 6, the attachment members 3... Have an interval corresponding to the reinforcing bar arrangement interval L. The tension is introduced into the strip 2 after the interleaved reinforcing bar units 5 and 6 are deployed, and the strip 2 is pulled. Marking becomes unnecessary, and a plurality of reinforcing bars 9 ..., 10 ... can be arranged at a time, and the arrangement work is simplified. Thereby, compared with the construction method which arranges a reinforcing bar material to the position decided one by one, the work labor in a reinforcing bar construction can be reduced.

  Further, after the interleaved reinforcing bar units 5 and 6 are deployed, tension is introduced into the strips 2 of the reinforcing bar connecting jigs 1 to place the strips 2 into a tensioned state, thereby reinforcing the reinforcing bars 9. Does not move in the lateral direction (the axial direction of each strip 2), and the bar arrangement state of the reinforcing bars 9 ..., 10 ... is not disturbed and the bar arrangement state is stabilized. Thereby, the bundling of the first reinforcing bar material 9 and the second reinforcing bar material 10 orthogonal to each other can be omitted, or the bundling location can be remarkably reduced, and the fatigue level of the worker can be reduced. Further, by reducing the fatigue level of the worker, the work efficiency can be improved and the work period can be shortened, and the safety of the worker can be improved by suppressing a reduction in the attention of the worker.

  Further, a tension means 4 for introducing tension into the strip 2 is provided with latching members 41 and 42 that are respectively latched on the beam bars 11, 12, 13, and 14, respectively. Since the one buckling member 41 is provided with the turnbuckle mechanism 43, the turnbuckle mechanism after the latching members 41 and 42 at both ends are latched to the beam bars 11, 12, 13, and 14, respectively. Tension is introduced into the strip 2 by rotating the body frame 44 of the turnbuckle mechanism 43 in a direction to reduce the distance between the screw rods 45, 46 at both ends of 43. Thereby, tension can be introduced into the strip 2 without using expensive parts and instruments, and the cost of the reinforcing bar connecting jig 1 can be suppressed.

  As mentioned above, although the embodiment of the reinforcing bar connecting method and the reinforcing bar connecting jig used therefor according to the present invention has been described, the present invention is not limited to the above-described embodiment, and does not depart from the spirit thereof. The range can be changed as appropriate. For example, in the above-described embodiment, the case where the slab bars are arranged by the interdigital reinforcing bar units 5 and 6 is described. However, the wall bars are arranged by the bar arrangement method and the reinforcing bar connecting jig according to the present invention. It is also possible to apply as appropriate to reinforcing bars in other parts.

  In the above-described embodiment, the strip 2 is formed of a flexible material. However, the present invention flexibly connects short strips made of a non-flexible material to flexibly. It may be configured by a mechanism having a characteristic.

  In the embodiment described above, the attachment member 3 is composed of the cylindrical portion 31 having a C-shaped cross section and the side plate portions 32, 32 on both sides thereof, but the attachment member according to the present invention is fitted with a reinforcing bar material. Any shape may be used as long as it is a combined structure, for example, it may be a mounting member having a structure in which a concave member (groove) into which a reinforcing bar material is fitted is formed in a rectangular parallelepiped member. It may be a string-like or belt-like attachment member tied to the material.

  Furthermore, in embodiment mentioned above, although the strip 2 is attached to the reinforcing bar materials 9 and 10 via the attachment member 3 attached to the strip 2, this invention was cut | disconnected from the strip, for example. The cylindrical mounting member may be fitted into the reinforcing bar material with the strip material sandwiched therebetween, and the strip material 2 may be attached to the reinforcing bar materials 9 and 10. Alternatively, the strip material may be attached to the reinforcing bar material by connecting the strip material and the reinforcing bar material using a string-like or belt-like attachment member that is not attached to the strip material.

  Further, in the above-described embodiment, the tension member 4 is attached to the both ends of the strip 2 by the hook members 41 and 42 that are hooked to the beam bars 11, 12, 13, and 14, respectively. Although the stop member 41 includes the turnbuckle mechanism 43, the present invention may introduce tension to the strip material by other tension means. For example, as shown in FIG. 12, a material (an annealed steel wire or the like) having plasticity that does not return to the original shape when twisted is used as the strip material 102. Then, both ends of the strip 102 are formed into a ring shape and wound around the beam bars 111 and 112 (fixed portions), respectively, and the strip material 102 is bridged between the beam bars 111 and 112 facing each other. When the tension is introduced into the strip 102, the end of the annular strip 102 is twisted using a rod-shaped tool 107 (such as a wrench) to introduce the tension into the strip 102. Specifically, the tip of the tool 107 is inserted into the end of the ring-shaped strip 102, and the tool 107 is rotated in a direction in which the end of the ring-shaped strip 102 is rotated (twisted). By using such a pulling means 104, the reinforcing bar connecting jig 101 can be made cheaper and the cost can be further reduced. In the other embodiment shown in FIG. 12, both ends of the strip 102 are looped and wound around the beam bars 111 and 112 respectively. However, in the present invention, only one end of the strip is looped. It is also possible to wrap around the fixed part and attach a latching member to the other end of the strip, and latch it to the fixed part with this latching member.
