In a conventional double flooring material, after installing a support at a predetermined interval on the floor surface of the room, floor plates manufactured to a certain standard are mounted to form a flat surface, and the supports are connected using a horizontal bar, etc., and at the same time, the floor material is stably secured support and support In most of these works, the main method is to fasten the screws in the up and down directions in a state where the ends of the horizontal bars are facing each other using an adapter separately installed on the pole side of the support.

In the case of such a double flooring, the floor plates can cause shock or vibration in the vertical direction due to external factors such as earthquakes, and large equipment, which are mostly heavy objects, is placed on the double flooring material, so a relatively large load is continuously applied. If the installation safety is not secured, the reliability of the product cannot be increased, and it can be a factor in causing a safety accident.

On the other hand, with respect to the installation technology of the double flooring material, Patent Registration No. 1200596 discloses that clips installed at both ends of the reinforcement bar are respectively coupled to and connected to the neighboring screw shaft to prevent the screw shaft from flowing due to horizontal forces such as earthquakes. Although the configuration example is disclosed, since the clip is inserted and coupled to the screw shaft, it is separated from the screw shaft even by a minute impact, so that the reinforcing function cannot be performed, and the clip coupled to the screw shaft descends along the outer surface of the screw shaft. The problem of changing the position arises.

In addition, in the case of the technology disclosed in Korean Patent Registration No. 1427240, when the coupling block is coupled, the coupling member is vertically inserted into the reinforcing bar and the corresponding coupling hole, and it is impossible to apply when the vertical installation space is narrow, Although it is possible to reduce the number of assembly parts, there is a limit to increasing the fastening strength with a downward bending protrusion, and strong vibration may cause breakage.
