PURPOSE:To improve the extent of floor impact noise interrupting performance by forming an outer frame with four floor large beams, anchoring two floor small beams, parallelly set up with each other, to the floor large beams, and locking a floor plate to the top of floor small beam. CONSTITUTION:An outer frame is formed with four floor large beams, while two floor small beams 24, parallel set up with each other, is anchored to the floor large beams, and a floor plate 25 is locked to the top of each floor small beam, forming a floor structure 21. Then, a connecting member 31, connecting these floor small beams, is attached to the opposite side of the floor small beams 24 where the floor structure 21 adjoins, while a ceiling hanger 32 is parallelly set up. Next, this ceiling hanger 32 is locked to the opposite floor large beam and the connecting member 31, and a blocking member 43 is installed in a clearance between the connecting member 31 and a lower floor ceiling board 42. With this constitution, a good damping effect is thus securable. |
