There are many places to take off shoes and to use the floor material as the floor. In residential buildings such as single-family houses or apartments, it is generally applied to the floor of the building by applying adhesives and then attaching the floorboard directly. However, a space where people move much, such as auditoriums or fitness centers, is constructed with a system floor that floors the floorboards. By forming a space between the floor and the floorboard, it is possible to attenuate the generated vibration and at the same time minimize the phenomenon that the impact is transmitted to the floor of the building, thereby reducing the interlayer noise.

The system floor is installed on the floor of the building, and the floor which supports the floorboard is placed on the upper part of the floor, and a space is formed between the floorboard and the floor. Korean Patent No. 10-1009217 describes a technique for such a system floor. And a skeleton forming member for supporting the floorboard is formed on the buffer member so that the floorboard and the floor of the building are spaced apart from each other. I am taking.

However, considering that the buffer member is a vibration absorbing material, noise due to friction between the skeleton body and the buffer member may occur. In particular, noise is generated due to rubbing of the skeleton-forming body and the portion of the buffer member facing the side surface of the groove. Also, as the fixing pin and the female screw formed in the buffer member are coupled with the male thread portion of the support, the fixing pin and the buffer member must perform rotational motion in order to adjust the height of the buffer member. This results in a disadvantage that it takes a lot of time for the floor panel to be constructed by the installer.
