In general, on trails and trails that require smooth walking by people, such as parks, lakes, and mountains, create a beautiful environment that is naturally friendly to the surrounding natural landscape, or promote pedestrian safety and convenience in terrain where pedestrians are difficult to walk. Various types of floor decks are constructed and used to create the optimal walking environment for the people.

In recent years, as interest in the surrounding environment has increased and in line with the phenomenon of pursuing a nature-friendly environment, the demand for floor decks using wood as a main material is increasing, and accordingly, it is applied to personal structures such as houses, pensions, etc. Trend.

Looking at the basic structural configurations of the floor deck, a fixed beam for supporting the overall structure on the ground according to the terrain, a joist that is disposed at regular intervals on the top of the fixed beam and serves as a bearing, and seats side by side on the top of the joist It consists of a bottom plate forming a walkable floor surface.

However, since the existing floor deck is fixed using a fastening means such as a nail or a screw when fixing the floor plate to a joist, the foot is impacted when walking and the walking feeling is significantly reduced. There was a problem in that the repeated loads along with the impact elements were transmitted to the bottom plate and the fastening means, causing damage and damage to the structure.

As a conventional technique disclosed in order to solve the above problems, Korean Patent Registration No. 820296 (2008.04.01.) Includes an i-beam extending in a longitudinal direction while having a protruding end in a width direction to support a flooring material, and In the installation structure of the flooring material, which is located on both sides in the width direction and is fixed to the lower part of the flooring material, and includes a finishing material and a brace material, it is formed integrally by being bent in two faces so as to form horizontal and vertical with the protruding end in the width direction. One surface forming a level with the protruding end is installed at a distance from the protruding end while being fixed to the lower portion of the flooring, and the other surface is perpendicular to the protruding end and a downwardly extending guide bracket and a downwardly extending protruding end while being fixed to one surface of the guide bracket. A fastening member penetrating through, and the fastening member penetrates and one surface of the guide bracket Between the upper surface of the protruding end, as the elastic body is formed of a structure installed while receiving compression force, a flooring installation structure is known that can induce convenience and smoothness when walking by pedestrians.

In addition, the Republic of Korea Patent Publication No. 111585 (2012.05.31.) Is a floor plate made of wood plywood seated side by side to allow pedestrians to walk directly, and the bottom plate is formed so as to be spaced apart from both ends of the bottom plate, respectively. The floor by connecting the fixed beam supported by the ground, the bottom plate and the fixed beam connecting the bottom plate and the fixed beam from the outside of the fixed plate and the fixed plate, and the bottom plate and the fixed beam on the other side of the fixed plate and the fixed beam As the plate is composed of a support member that applies reinforcing force when the plate is deformed by a load, and a soft plate fixed between the bottom plate and the fixed beam, it is composed of a shock absorber that adds buffering force to the bottom plate and the fixed beam. A buffer structure for a floor deck that can be secured is known.

In addition, in the registered patent publication No. 16,816,4 (2016.12.20.), A base frame fixed to the floor to be constructed; A fixed frame fixedly installed to intersect at an upper side of the base frame; A buffer pad coupled to the fixed frame to provide a cushion feeling on the upper side of the fixed frame; A magnetic material interposed between the fixed frame and the buffer pad so that the buffer pad can be magnetically coupled to the fixed frame; A plurality of deck boards which are seated in the same direction as the base frame on the upper side of the buffer pad and through which fastening holes having stepped jaws are penetrated; A fastening piece penetrating through the fastening hole so that the plurality of deck boards are fixed to the buffer pad and fastened to the fastening frame; And it is installed to be coupled to the fastening piece at a step of the fastening hole, a through-hole having a screw thread is formed on the inside to prevent the loosening of the fastening piece; Including, but, the buffer pad is formed to protrude downward so as to protrude downward on both sides to surround a part of the lower side of the fixed frame, and is formed to protrude so that a plurality of gap holding jaws are spaced apart from the upper portion of the gap holding jaw. The separation distance is formed equal to the width of the deck board, and a V-shaped guide groove is formed in the longitudinal direction so as to penetrate through the screw coupling method by an external force on the upper side corresponding to the fastening hole, thereby providing a cushion feeling when walking. Deck structures having a shock absorbing function capable of improving durability are known.

However, in the case of the above-mentioned prior art, in the case of the registered patent publication No. 820296, an elastic body and a fastening member are applied to the floor deck so that the buffer force can be applied according to the walking of the floor deck. Since installation must be applied, installation work is very cumbersome and takes a lot of work time, and load caused by pedestrian walking is applied to the fastening member and the elastic body, causing frequent damages, causing inconvenience and maintenance costs due to frequent repair work. It takes a lot and further, it is difficult to generate an effective elastic force only with the elastic body provided in the fastening member, and thus there is a problem in that its efficiency for cushioning is significantly reduced.

On the other hand, in the case of the above-mentioned prior art, in the case of the registered patent publication No. 1153985, only one buffer that adds a buffering force between the base plate and the fixed beam is applied, so that a buffering force capable of ensuring pedestrian safety is configured to act. Since the inlet groove for fixing the sieve is configured to be applied to the fixed beam, there is a problem in that it is very difficult and requires a lot of work cost to directly process the inlet groove on the fixed beam made of structural steel.

In addition, in the case of the above-mentioned prior art, in the case of the registered patent publication No. 1689814, when the buffer pad applied to induce elasticity between the deck board and the fixed frame (joist) deteriorates by itself, the elastic ability is lost and the entire structure must be removed. Therefore, there is a serious problem in maintenance work, and when fastening the deck board on the fixed frame, the fastening piece penetrates the deck board and buffer pads and screwes on the fixed frame, so all the components from the fastening piece are collectively screwed. There was a problem in that a practical buffering action against the shock applied to the deckboard was not feasible.
