[Prior art]

 Conventionally, when arranging slab reinforcements for structures, a plurality of main reinforcements and distribution reinforcements, each of which is made by processing a single rebar with a prescribed diameter to a prescribed size, are bundled together, transported to the work site, and unloaded onto a slab formwork. . Then, first align the main rebars on the slab formwork in accordance with the spacing between the main rebars and the rebars that were previously marked with chalk on the slab formwork, and place the rebars on the main rebars at right angles to the main rebars. After that, the intersections of the main muscles and the muscles to be reinforced are tied with binding lines to arrange the muscles. After finishing the reinforcement, a spacer was bit between the slab formwork and the slab muscle to secure the concrete covering thickness of the slab muscle.

Further, as a method for arranging the reinforcements of the slab or the PC floor and the wall produced in the factory in a labor-saving manner, the main reinforcements and the reinforcement reinforcements having a predetermined diameter are welded or bundled in a mesh shape at predetermined intervals. When it is molded and used in the field, it is transported to the work site by stacking a plurality of mesh-shaped rebars processed into a size that can be transported in a flat state on the truck (about 2.5 m × 6.0 m) and transporting them to the work site. Unload onto the formwork. Next, the mesh-shaped reinforcing bars are arranged one by one on the slab formwork, and the end portions of the mesh-shaped reinforcing bars are arranged so as to overlap each other by a predetermined joint length and arranged. After finishing the rebar arrangement, a spacer was placed between the slab formwork and the mesh-shaped rebar to secure the concrete cover thickness of the mesh-shaped rebar.

[Problems to be solved by the device]

 In the work of arranging the above-mentioned conventional single rebar on the floor to be laid, the slab formwork is marked, the rebars are laid one by one, and the intersections of the main rebar and the reinforcing bar are tied together. There were a lot of bar arrangement processes at work, and the work was complicated, requiring a large number of reinforcing bars. In addition, the rebar method using mesh-shaped rebars is bulky because the mesh-shaped rebars are transported in a flat pile, and the loading and unloading work of materials is troublesome. It was troublesome because it had to be carried and arranged by a reinforcing bar. In addition, since the mesh-shaped rebar is cut into a size of about 2.5 m x 6.0 m due to transportation restrictions, there are problems that the number of joints increases and it takes time, and there is much loss of rebar. In view of this, the present invention aims to simplify the work in the bar arrangement work to be arranged in the structure, to save labor, to facilitate the processing and transportation of the bar reinforcement material, and to reduce the loss of the reinforcing bar. .

The reinforcing bar unit has two rows of reinforcing bar holding materials in which a flexible band is provided with a plurality of holes at regular intervals, and both ends of a reinforcing bar of a predetermined length are respectively placed in corresponding holes of the two reinforcing bar holding materials. By inserting and holding it, it has a sloping shape. In addition, in the flexible band material that constitutes the reinforcing bar holding member, the portion near the hole for inserting the reinforcing bar is bent 90 degrees, and each hole is formed slightly smaller than the outer diameter of the reinforcing bar to be inserted into it. A notch is provided on the periphery of the hole.

[0006]

[Action]

 In the rebar unit of the present invention, two strip-shaped rebar holding members having holes at regular intervals are arranged in parallel, and both ends of a rebar having a predetermined length are inserted into each hole of the rebar holding members on both sides. Since it is formed into a sloping shape, it can be rolled and packed in a roll shape, and it is easy to transport in the packed state, and it can be rewound from the packed state onto the floor or PC plate to be laid out. If so, the reinforcing bars can be easily arranged. In that case, since each rebar is inserted into the holes provided at regular intervals in the reinforcing bar holding material, the rebar spacing can be set to a predetermined value simply by unwinding from the packed state. In addition, since the reinforcing bar holding member of the flexible strip is bent 90 degrees in the vicinity of the hole, the reinforcing bar unit can be easily rolled into a roll with the reinforcing bar inserted in the hole. Further, since the hole is slightly smaller than the outer diameter of the reinforcing bar and the notch is provided at the periphery of the hole, the reinforcing bar can be held in a fixed state by the reinforcing bar holding member simply by inserting the reinforcing bar into the hole.
