Walkways and hiking trails, which generally require people to walk smoothly, such as parks, lakes, and mountains, are designed to create a beautiful environment that is environmentally friendly, in line with the surrounding natural landscape, or to provide pedestrians with safety and convenience in pedestrians' Various types of floor decks have been constructed and used as a means of creating an optimal walking environment for the user.

In recent years, the demand for floor decks using wood as a main material has been increasing increasingly due to the increasing interest in the surrounding environment and the pursuit of a nature-friendly environment. Accordingly, it is applied to individual buildings such as houses and pensions There is a trend.

The basic structure of the floor deck includes a fixed beam for supporting the overall structure on the ground according to the terrain, a joist arranged at a predetermined interval on the fixed beam to serve as a support, And a bottom plate constituting a floor surface capable of being walked.

However, since the existing floor deck is fixed by fastening only the fixing screw in the process of fixing the bottom plate to the joist line, safety incidents occur frequently due to the impact of the foot due to the impact of the foot, resulting in frequent safety accidents.

However, the above-described known elastic decks are intended to guide the elasticity by interposing the elastic member on the upper part of the joist line or the lower frame, and fixing the rubber to the elasticity of the technical wood. The structure of the deck is very complicated, There is a serious problem that the elasticity is lost and the whole structure is demolished and repaired and the elasticity can be maintained to some extent but the shape of cracks and warping due to shrinkage, There was a problem that deformation occurred.

On the other hand, Korean Patent No. 10-1208485 (Nov. 29, 2012) discloses a wooden deck installed on the upper surface of a lower structure constituting the bottom surface of a structure, which is formed in a rectangular shape elongated in the longitudinal direction, A wood base layer (100) formed in direct contact with a user's foot at the time of beating action, a plurality of non-slip ridges (102) formed on an upper surface thereof and configured to maintain the texture of the wood; The wood base layer 100 is formed in the same shape as the wood base layer 100 and is formed in close contact with the lower surface to prevent a ringing of the wood base layer 100 according to an impact amount due to an external impact, A shock-absorbing foamed layer 200 formed of a urethane foam having a plurality of microvoids 210 formed by foaming urethane to primarily absorb the impact transmitted thereto; Absorbing foamed layer 200 and is formed in the same shape as the wood base layer 100. The external impact transmitted from the impact-absorbing foamed layer 200 is secondarily absorbed to the lower structure A shock-absorbing elastic layer 300 configured to apply elastic force to the wood base layer 100 so that the wood base layer 100 is prevented from being transmitted and the deformation of the wooden base layer 100 due to an external impact is returned; A foamed adhesive layer 400 applied to the lower surface of the shock-absorbing foamed layer 200 and adapted to firmly engage the shock-absorbing elastic layer 300 on the lower surface of the shock-absorbing foamed layer 200, The elastic layer 300 includes a weatherproof urethane layer 310 formed to correspond to the lower surface of the shock-absorbing foamed layer 200 to which the foamed adhesive layer 400 is applied and to generate a restoring elastic force against an external impact; A soft urethane layer 320 corresponding to the lower surface of the weatherproof urethane layer 310 and adapted to be cushioned against an external impact; And a urethane primer layer 330 applied to the lower surface of the soft urethane layer 320 and closely attached to the upper surface of the lower structure.

However, in the above-mentioned Korean Patent No. 10-1208485, the shock absorbing wood deck has many layers of impact absorbing layers to provide excellent elastic performance, but the structure is complicated and the shock absorbing wooden deck must be separately manufactured when the shock absorbing wooden deck is constructed.
