摘要

The present invention relates to a structure for preventing interlayer noise and interlayer vibration in a multi- A central cylinder 312 with an open bottom; A disk 311 formed outwardly from the lower end of the cylinder 312; A plurality of strut ribs 313 extending radially from the outer surface of the cylinder 312 and having a lower end joined to an upper end of the disk 311; A plurality of buckling prevention ribs 314 connecting the plurality of support ribs 313 and having a lower end joined to an upper end of the disc 311; , / RTI The present invention provides an improved interlaminar soundproofing mouthpiece 300 that is installed on an upper portion of a slab S in a state where an elastic body 322 is inserted into the cylinder 312 to absorb a walking impact transmitted from the upper portion of the slab S . In addition, using the improved interlaminar soundproofing vents 300, Slab S; A plurality of the modified interlayer noise-preventing vents 300, which are mounted on the slab S with the elastic body 322 inserted therein; A floor plate (200) and a finishing material (100) stacked one on top of the modified interlayer noise insulating floor (300); , / RTI Wherein a walking impact transmitted from the upper portion is transmitted to the modified interlayer noise suppression port (300) so that the modified interlayer noise suppression port (300) absorbs the walking impact and attenuates the shock.
