1A is a perspective view of a soundproof material coated on an inner surface of a conventional deck plate, and FIG. 1B is a front view of a state in which a conventional deck plate is installed.

Referring to FIG. 1A, a conventional soundproof deck plate 1 is coated with a soundproofing material 2 on the outer surface of the deck plate 1, that is, a portion in contact with concrete during installation, and the inside of the deck plate 1. The sound insulation material 2 may be selectively coated on the surface. In addition, the deck plate (1) is bent in a plate shape in the shape of a square wave convex portion 7 and the concave portion 8 alternately repeated but the cross section of the convex portion 7 and the concave portion 8 is trapezoidal A plurality of protrusions 6 and grooves 5 are formed on the surface of the plate so that the soundproofing material 2 can be easily bonded. In order to increase the strength of the convex portion 7 and the concave portion 8, a reinforcing force 4 is formed on the surface of the convex portion 7 along the longitudinal side of the plate, and both ends of the plate are formed of the plate. It extends so as to cover the whole upper surface of the H-beams 3 which are spread.
