This is to prevent the flow or conduction of the reinforcing bar by the external force applied to the reinforcing bar by forming the contact area on which the reinforcing bar is formed in a slightly smooth curve.

In other words, when the rebar is mounted on a flat surface, the contact area between the rebar and the reinforcing bar is wide so that it can resist external forces within a certain range acting as a vertical load. The composite load (vertical load + horizontal load) acts on the end of the reinforcing bar of the reinforcing bar, and the external force of the compound load is greatly deviated from the central axis of the reinforcing bar. May occur.

On the other hand, when the rebar is mounted on a gentle curved surface, the external force acting on the reinforcing bar acts near the central axis of the reinforcing bar may help prevent the reinforcing of the reinforcing bar.

Meanwhile, a plurality of protrusions p may be formed on the bottom of the first reinforcing bar 10 to reduce the contact surface with the bottom surface.

In FIG. 2, although the protrusion p formed on the bottom of the first reinforcing bar 10 is illustrated, a plurality of protrusions p is also formed on the bottom of the second reinforcing bar 20 and the third reinforcing bar 30. It can be formed to reduce the contact surface with the bottom surface.

In addition, when the second reinforcing bar 20 is assembled on the upper part of the first reinforcing bar 10, the bottom of the second reinforcing bar 20 on the upper surface of the first reinforcing bar 10 It may be provided to form a mounting groove (not shown) corresponding to the formed protrusion (p) to be assembled correspondingly.

As described above, the assembled reinforcing bar according to the present invention, by mounting the upper and lower reinforcement to the assembled single reinforcing bar using a plurality of reinforcing bar is configured to be assembled, the reinforcing bar by the weight of the reinforcing bar It can have a structural characteristic that is not conductive, and can prevent the reinforcement of the reinforcing bar by the load applied to the reinforcing bar, and at the same time can facilitate the height adjustment and installation work.

In addition, by ensuring the effective dancing of the same slab reinforcement of the design to prevent the crack of the concrete, thereby improving the quality of the structure, by adjusting the height of the reinforcing bar freely by the combination of the reinforcing bar, the state of the floor reference surface The construction can be done easily and accurately.

As mentioned above, although the present invention has been described by way of limited embodiments and drawings, the technical idea of the present invention is not limited thereto, and a person having ordinary skill in the art to which the present invention pertains, Various modifications and variations may be made without departing from the scope of the appended claims.
