Ventilation grooves are formed on all sides, the building floor is in contact with the base surface of the floor with the cushioning material inserted inside the concave groove, the air can be circulated through the protrusion (5) in contact with the base surface Construction materials are known.

In the case of the conventional floor construction materials as described above, the floor material is constructed by combining a body made of a hard plastic material and a foam support for supporting the body. At this time, the foam support for supporting the main body also serves as a formwork during concrete pouring.

Therefore, in the case of the conventional floor construction material, there is a need to separately produce a main body of a rigid plastic material and a lower foam support for supporting the same, and also, by assembling the upper body and the lower foam support respectively during the construction of the floor construction material in the field. As the construction method is cumbersome, the construction method is cumbersome, and the construction period is not only long, but also when the construction material body and the foam support are not tightly coupled to each other during construction, and the main body and the foam support are lifted up, it causes noise due to resonance. There were problems.
