Problems solved by technology

[0002] At present, the sound insulation structure of residential underground fan rooms usually adopts sound-absorbing walls and sound-absorbing ceilings to reduce the noise impact on the upper-floor residents. Since there is no system to consider sound insulation, noise interference from noisy rooms such as fan rooms to upstairs residents occurs from time to time.

Abstract

The invention discloses a sound-insulation structure for an underground fan room of a house. In order to achieve the purpose, the technical scheme of the invention is as follows: the sound-insulation structure of the underground fan room of the house comprises a fine aggregate concrete surface layer (1), a shock absorption pad (2), a reinforced concrete slab (3), a rock wool sound absorption board (4), cement mortar gridding cloth auxiliary rivets (5), an air layer (6), a mineral wool sound absorption board (7), a concrete pad layer (8), packed soil (9), a reinforced concrete slab (10), an underground fan room (11), a bedroom (12) and a reinforced concrete wall (13). The sound-insulation structure has the benefits that with the adoption of the structure, the noise generated by the fan room can be absorbed, a noise transmission route is blocked, and a silent environment is created for upstairs residents.

Description

technical field [0001] The invention relates to an underground building sound insulation structure, in particular to a residential underground fan room sound insulation structure. Background technique [0002] At present, the sound insulation structure of residential underground fan rooms usually adopts sound-absorbing walls and sound-absorbing ceilings to reduce the noise impact on the upper-floor residents. Since there is no system to consider sound insulation, noise interference from noisy rooms such as fan rooms to upstairs residents occurs from time to time. . Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a sound insulation structure for underground fan rooms in residential buildings. Shock pad, reinforced concrete slab, rock wool sound-absorbing board, cement mortar grid cloth supplemented by rivets, air layer, mineral wool sound-absorbing board, concrete cushion, plain soil compaction, rein...
