A device for attenuating floor impact sound and vibration in a building is provided to facilitate installment of a hot water pipe with its easy positioning and to absorb noise and vibrations by using integrated unit blocks and an anti-vibration member. A device for attenuating floor impact sound and vibration in a building comprises a plurality of unit blocks(10) combined to each other in a horizontal direction and contouring a single plate, an anti-vibration rubber member(30) combined to a lower side of the unit blocks, and a pipe bracket(40) combined to an upper side of the unit blocks and receiving a pipe(50). The unit block comprises an upper plate(12) having a plurality of first connecting holes(14) contoured with screw tabs, a lower plate(16) spaced away from the upper plate, having a plurality of second connecting holes(18) contoured with screw tabs, first and second side plates(20,24) disposed on opposite ends of upper and lower plates, each one end connecting to the upper plate and another end connecting to the lower plate to define facing side walls, a receiving groove(22) provided on the first side plate and recessed towards the second side plate, a connecting projection(26) provided on the second plate and projected to the opposite side of the first side plate from the surface of the second plate, and a plurality of reinforcing plates(28) whose one end is coupled to the upper plate and another end is coupled to the lower plate, disposed between the first and second side plates with a regular internal, parallel to the first side plate. The unit blocks are combined to each other by inserting the connecting projection of the second plate to the receiving groove of the first side plate of adjacent unit block. The anti-vibration rubber member comprises a body part(32) made of rubber material having a predetermined height, and whose bottom side makes contact with a boundary of each floor of the building, and a buffer screw(34) disposed on an upper end of the body part and screwed to the second connecting hole. The pipe bracket comprises a bracket screw(44) screwed to the first connecting hole, and a head(42) combined to an upper part of the bracket screw, having a pipe receiving groove. Floor impact sound and vibration in a building can be reduced by pouring concrete to the bottom of the anti-vibration rubber and an upper part of the pipe bracket. |
