The present invention relates to a reinforcing bar support structure and a construction method thereof that can be easily and firmly installed by simply inserting and combining the lower end without welding.

In general, in the foundation work for building construction, the foundation lower and upper foundation reinforcement are installed. Recently, with the generalization of high-rise buildings, the depth of the MAT foundation deepens, so that the reinforcement of the foundation upper part is poured on the upper part of the foundation. As the reinforcing bar is installed high from the floor and the amount of reinforcement required for the foundation work increases, it is required to install a reinforcing bar support structure under the foundation upper reinforcement in order to prevent sagging of the upper reinforcing bar and for workers to work safely on the reinforced upper foundation. Became.

Conventionally, there was no specially standardized structure or construction method for the reinforcing bar support structure installed under the upper reinforcing bar on the foundation, so the reinforcing reinforcement working on the site may install a reinforcing bar support structure under the upper reinforcing bar at the base of the foundation. Not only is it structurally unstable as it is made and installed in the form of, but also has a problem that the air lengthens as such a reinforcing bar support structure is manufactured and installed in the field.

It is provided, and is fixed to the upper edge of the vertical member is configured to adjust the height of the connection support member while supporting the upper base of the reinforcement height adjustment unit.

However, the prior document 2 as described above requires a rod guide member that is welded to the inside of the vertical structure and further requires a rod guide member that accommodates the reinforcing bar height adjustment rod, making it difficult not only to work, but also to increase the manufacturing cost due to the increase in the number of parts, which results in economical efficiency. There was a falling problem.

In addition, in the case of mounting a reinforcing bar support composed of a'C' on the upper end of the connecting support member, the manufacturing process is complicated because the reinforcing bar support is fixed to the connecting support member by welding.

In addition, since the rebar height adjustment rod inserted into the rod guide member and coupled to the connection support member can only move in the vertical direction, it cannot move left or right, so that the left and right adjustment of the reinforcing bar holder is impossible.
