Recently, our society, with the rapid development of information and communication, has introduced the concept of building automation and office automation in the field of architectural design and construction technology. In particular, the era of office automation and the establishment of intelligent systems determines the success of a company. In other words, maximizing the efficiency and productivity of information management by providing a pleasant and comfortable working environment where employees can be motivated and creative has become a prerequisite for differentiated competitiveness.

Therefore, the rapid development of intelligent function of the building necessitates a variety of highly functional wiring network, it is necessary to use the flooring material to protect the various wiring and secure the efficient wiring processing space. Various floor wiring means and methods or flooring materials having functions and qualities required in a suitable office environment have been developed, for example, floor ducts, buried methods in slabs, access floors, and the like. In particular, the access floor is widely used today because of its excellent efficiency in wiring processing.

However, each of them had their own advantages as well as their problems. In short, the floor duct is convenient to install, but there is a structural limitation on the wiring capacity, making it difficult to expand a new network or to add facilities. When the wiring was changed, it was difficult to cope with this. In addition, the buried method in the slab is stable because the wiring is embedded in the slab, but has a problem that the overall construction area is reduced because the overall slab thickness is thick. Accordingly, the access floor, which is an improved flooring material considering many of the above disadvantages, is generally used in office buildings today.

However, this also has some minor but other disadvantages. Briefly, through the structure of the access floor shown in FIG. 1, the base panel 1 and the panel 1 are spaced apart from the floor surface. It is composed of a support means (2), the support means (2) is a pedestal (3) arranged at a predetermined interval on the floor to be installed, and the stringer (4) or connecting table (4) connecting the pedestal (3) ) And was fastened by screwing together (4a). However, such a screw (4a) coupling required a fastening time that takes a certain time for its coupling, and if the load and fluctuations in the upper part is continuously transmitted over time, the coupling becomes loose, accordingly There was a structural disadvantage that noise is generated at the joint.

The present invention is to solve this problem, by improving the structure of the base and the stringer constituting the support means of the flooring material, significantly reducing the fastening time and construction period of the flooring material, and firmly fixed and maintained even over time noise It is an object of the present invention to provide a joining means of a double floor material that can be provided with a double floor material does not occur.
