Assembly type functional floor

The present invention includes a flooring body 110， a first coupling portion 120 and a second coupling portion 130， the flooring body 110 in contact with each other is coupled by the first and second coupling portion (120，130) ， Flooring body 110 is arranged in a number to be parallel to the construction surface for the construction of the floor， may have a rectangular parallelepiped structure， the flooring body 110 is provided with a natural cork sheet layer 111 on the bottom， On the natural cork sheet layer 111， a plurality of wood layers 112a are stacked and attached to each other in a staggered direction， and a plywood finishing layer 113 is attached to the plywood 112. The present invention relates to a prefabricated functional floor. According to the present invention， it not only blocks noise with material properties， but also reduces noise by converting sound energy into thermal energy through friction， compression， and diffusion when noise passes through the assembly gap. ， Can have excellent sound insulation effect And， as well as the use of natural Forest products do not generate hazardous substances， By avoiding the use of the floor adhesive during construction， it is possible to provide an environmentally friendly flooring material.
