The present invention relates to an interlayer sound insulation material for construction having a first base member and a second base member coupled to the lower portion of the first base member. The interlayer sound insulation material comprises: a plurality of first base members formed at regular intervals and including a first buffer assisting member having an edge portion and a buffer reinforcing member formed in the inner center of the edge portion in a cross state and connected to the edge portion; and a plurality of second base members formed at regular intervals and including a second buffer assisting member which has the same shape as the edge portion and a smaller size than the edge portion in a position corresponding to the first buffer assisting member. Especially, the present invention is capable of efficiently buffering, dispersing, and extinguishing noises or the like generated from an upper floor in order to prevent the noise or the like generated from an upper floor of a multi-level building such as an apartment or the like from being transmitted to a lower floor. |
