PURPOSE: A noise control deck plate is provided to improve interlayer soundproofing efficiencies by coating the existing deck plate with sound absorbing materials. CONSTITUTION: The noise control deck plate(1) is formed by folding a board to form convex parts(7) and concave parts(8) by turns, wherein the sections of the convex part(7) and the concave part(8) are formed in a trapezoid, many projections(6) and grooves(5) are formed on the surface of the board to adhere sound absorbing materials(2) easily, stiffening furring(5) is formed along a vertical side of the board on the surface of the convex parts(7) to increase the stiffness of the convex parts(7) and the concave parts(8), and both ends of the board are extended to cover up the entire top of an H-beam. |
