Embodiment 1

[0052] Such as figure 1 As shown, a room-in-room sound insulation and shock absorption system includes a sound insulation and shock absorption floor 1 , a sound insulation wall structure 2 , a sound insulation ceiling structure 4 , a sound absorption wall structure 3 and a sound absorption ceiling structure 5 . The sound-insulating and shock-absorbing floor, the sound-insulating wall structure, the sound-insulating ceiling structure, the sound-absorbing wall structure and the sound-absorbing ceiling structure constitute the sound-insulating and shock-absorbing room-in-room 10 . A sealed sound-insulating and shock-absorbing window 9 can be set on the sound-insulating wall structure and the sound-absorbing wall structure to facilitate observation.

[0053] The lower ends of the sound-insulating wall structure and the sound-absorbing wall structure are connected to the concrete layer 17 of the corresponding sound-insulating and shock-absorbing floor through sealing pads 23 . The...

Embodiment 2

[0106] The difference from Embodiment 1 is that the sound-insulating and shock-absorbing floor may not be provided with the bottom sound-insulating and shock-absorbing layer 12 and the bottom concrete slab 13 . Then each shock-absorbing pad can be fixed on the concrete floor with construction glue to prevent the shock-absorbing pad from shifting.

[0107] That is: the sound-proof and shock-absorbing floor is followed by sound-proof and shock-absorbing layer, wood fiber board layer, waterproof layer, concrete layer, wooden dragon skeleton layer, wood lining layer, plastic foam lining layer and composite wood floor layer from the lower end to the upper end. All the other structures and construction methods alternate with Embodiment 1, so they are not repeated.

[0108] According to the test, the air sound insulation of Example 2 can reach 80-90db, which has a good sound insulation effect.

Embodiment 3

[0110] The difference from Embodiment 2 is that in buildings that require less strict sound insulation and shock absorption, no soft sound-absorbing and shock-absorbing layer may be provided. All the other structures and construction methods alternate with Embodiment 2, so they are no longer repeated.

[0111] According to the test, the air sound insulation of Example 3 can reach 70-79db, which has a good effect of sound insulation.

Abstract

The invention belongs to a room-in-room sound-insulation and shock-absorption system and a construction method thereof. The system comprises a sound-insulation and shock-absorption floor, a sound-insulation wall body structure, a sound-insulation ceiling structure, a sound-absorption wall body structure and a sound-absorption ceiling structure, wherein the sound-insulation and shock-absorption floor forms the ground of a sound-insulation and shock-absorption room; the sound-insulation wall body structure and the sound-absorption wall body structure form a double-layer wall body of the sound-insulation and shock-absorption room; or the sound-insulation wall body structure, the sound-absorption wall body structure and a soft body sound-absorption and shock-absorption layer between the sound-insulation wall body structure and the sound-absorption wall body structure form the double-layer wall body of the sound-insulation and shock-absorption room, an outer air sound-insulation layer is arranged in a distance space between a wall body base layer and the sound-insulation wall body structure, and an inner air sound-insulation layer is arranged in a distance space between the sound-insulation wall body structure and the sound-absorption wall body structure. According to the room-in-room sound-insulation and shock-absorption system, an ideal sound-insulation effect is achieved by virtue of reasonable structure and method. The room-in-room sound-insulation and shock-absorption system has the advantages that the method is feasible, the structure is simple, the cost is low, the sound-insulation effect is good, and the system is firm and durable.

Description

technical field [0001] The invention belongs to a room-in-room sound insulation and shock absorption system and a construction method thereof. Background technique [0002] In recent years, with the rapid development of my country's digital broadcasting technology, the requirements for the craft room of the digital broadcasting building have become more and more stringent. The structure achieves the purpose of controlling the sound quality of the space and meeting the requirements of sound insulation and noise reduction. Therefore, the acoustic decoration not only needs to meet the design requirements on the outer surface of the decoration, but also the structure and materials of the rear part of the decoration surface must meet the design requirements. Otherwise, the acoustic index test after construction will fail, resulting in waste of rework. In order to avoid atmospheric noise generated when the medium between rooms is excited by sound energy and direct mechanically exc...
