And the operation of winding the assembled rebar 3 in a roll shape. The workbench 15 having a predetermined height and a roll-shaped braided reinforcing bar unit 1 placed on the workbench 15 are covered from above to accommodate the braided-rebar unit 1 and roll-shaped braided rebar. Since the container 16 provided with the fastening means 25 for fastening the unit 1 to the container 16 and the moving means 17 for moving the container 16 between the accommodation position and the non-accommodation position are provided, a plurality of reinforcing bars are provided. The operations of assembling the assembled rebar 3 by connecting 2... And the operation of winding the assembled rebar 3 in a roll shape are each performed on the work table 15 and are easier to perform than performing bending downward. As a result, the work of creating the interleaved reinforcing bar unit 1 becomes easy, and the work efficiency can be improved.
Further, in a state where the container 16 is arranged at the non-contained position, the roll-shaped interlaced reinforcing bar unit 1 is moved to the place of the container 16, and then the container 16 is moved to the accommodated position, thereby forming a roll shape. The interleaved reinforcing bar unit 1 is accommodated in the housing 16 without lifting and carrying the interleaved reinforcing bar unit 1. Thereby, the operation | work which accommodates the roll shaped braided reinforcing bar unit 1 in the accommodation tool 16 becomes easy, and work efficiency can be improved.
Further, by tightening the braided reinforcing bar unit 1 to the container 16 by the tightening means 25, it becomes possible to transport the braided bar unit 1 together with the container 16. As a result, the work of transporting the interlaced reinforcing bar unit 1 becomes easy, and the work efficiency can be improved.

As mentioned above, although the embodiment of the production method of the braided reinforcing bar unit according to the present invention and the connecting jig, the core material, and the assembly equipment used therefor has been described, the present invention is not limited to the above-described embodiment, Changes can be made as appropriate without departing from the spirit of the invention.
For example, in the above-described embodiment, the connecting strip 6 is sandwiched between the reinforcing bar 2 and the connecting jig 7. However, in the present invention, a plurality of connecting jigs are arranged on the connecting strip. The structure attached with the space | interval equivalent to the line | wire space | interval L may be sufficient.

  Further, in the above-described embodiment, the positioning member 8 is loosely inserted into the inserted portion 10, and the connecting jig 7... Moves along the positioning member 8 when the assembled rebar 3 in a gathered state is expanded. In addition, after the assembled rebar 3 is completely expanded, the positioning members 8 are removed from the insertion portions 10 of the connecting jigs 7. However, in the present invention, the positioning member is pressed against the claw portion. The structure which adhere | attaches and a to-be-inserted part and a positioning material do not shift | deviate may be sufficient. In this case, after the connecting jig is attached to the reinforcing bar material, the positioning member is removed from the inserted portion, and then the assembled reinforcing bar in a gathered state is expanded.

  Further, in the above-described embodiment, after the reinforcing bar 2a on the most rear end side is hooked on two or more hooks (not shown) attached to the core material 4, the core material 4 is directed toward the front end side. The assembled rebar 3 is wound around the core material 4 by rolling, but in the present invention, the rear end portion of the assembled rebar may be wound around the core material by an operator's manual operation.

  Moreover, in above-mentioned embodiment, although both ends 9c and 9c of the fitting part 9 which comprises the connection jig | tool 7 are a rectangular parallelepiped shape, as for this invention, either one edge part of a connection jig is a rectangular parallelepiped shape. The intermediate part of the connecting jig may have a rectangular parallelepiped shape, or the entire connecting jig may have a rectangular parallelepiped shape.

  In the above-described embodiment, the gear 12 a attached to the handle 12 is engaged with the gear hole 11 a formed in the end surface of the core body 11, so that the handle 12 is attached to the end of the core body 11. Although provided, the present invention may be a core material in which the core material body and the handle are integrated from the beginning.

  Further, in the above-described embodiment, the rotating shaft 30 that rotates in the vertical direction is interposed between the distal end portion of the top plate portion 19 of the receiving device 16 and the leg portion 20a on the distal end side. 16 can be rotated in the vertical direction, and the container 16 is rotated between the accommodation position and the non-accommodation position by rotating the container 16 rotatably attached by the moving means 17. However, the present invention may have a configuration in which a rotating shaft is interposed between the container and the work table so that the entire container rotates, and the container is moved linearly by the moving means. By doing so, the structure which moves the container 16 between an accommodation position and a non-accommodation position may be sufficient.
