Here, Figures 7 to 8 illustrate the exploded and combined perspective view of the state in which the height adjustment reinforcing bar 60 is disposed in the reverse direction, as described above, the height adjustment reinforcing bar 60 is forward or reverse as necessary Can be optionally combined with

On the other hand, the first rebar portion 12 of the first reinforcing bar 10 and the second rebar portion 22 and the third rebar portion of the third reinforcing bar 30 of the second reinforcing bar 20 32 and the upper surface of the rebar mounting portion 62 of the height adjustment reinforcing bar 60 is gentle with respect to the center, it may be formed of a convex spherical surface.

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 (not shown) may be formed on the bottom of the first reinforcing bar 10 to reduce the contact surface with the bottom surface.

In addition, a plurality of protrusions may also be formed on the bottom surfaces of the second reinforcing bar 20 and the third reinforcing bar 30 to reduce the contact surface with the bottom surface.

Here, when the second reinforcing bar 20 is assembled from the top of the first reinforcing bar 10, the bottom surface 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 to be assembled correspondingly.

As described above, the assembled reinforcing bar support including the insert according to the present invention may have a structure to prevent concrete from flowing into the insert without using nails or adhesives when placing concrete, When placing concrete, the upper and lower reinforcing bars are mounted on the assembled single reinforcing bar by using a plurality of reinforcing bar supports that can be assembled to take advantage of the structural characteristics such that the reinforcing bar is not conducted by the weight of the lower bar. It prevents the reinforcement of the reinforcing bar by the load applied to the reinforcing bar while making it easy to adjust the height and install, and to ensure the effective dancing of the slab reinforcing bar which is the same as the design. Thereby, the quality of a structure can be improved.

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.
