PURPOSE: An interlayer sound insulation material for construction is provided to effectively absorb and reduce noise and impacts and to ensure easy manufacture and installation. CONSTITUTION: An interlayer sound insulation material for construction comprises a first shock absorbing medium(100), a plurality of shock absorbing units(110), a concavo-convex part(120), a second shock absorbing medium(300), and a crushing prevention unit(200). The shock absorbing units are located at regular intervals in a symmetrical stepped shape under the first shock absorbing medium. The concavo-convex part is formed in the direction on the top of the first shock absorbing medium, forming a lattice with the shock absorbing unit. The second shock absorbing medium is coupled to the top of the concavo-convex part. The crush prevention unit is attached to the top of the second shock absorbing medium. |
