Description
Technical Field
The utility model relates to a sound insulation wall body technical field, more specifically relate to a modular sound insulation wall.
Background
The sound insulation capability of the indoor space depends on the sound insulation quantity of the wall, the wall with the air sound insulation quantity STC larger than or equal to 50dB is generally called as a sound insulation wall, and the sound insulation performance is greatly influenced by the structure and the material of the wall. The general sound insulation standard of rooms of houses and offices is 45dB, and the general sound insulation standard of five-star hotel guest rooms is more than or equal to 50 dB. Therefore, in some places with high requirements on sound insulation, such as a five-star hotel guest room, a multifunctional conference room, a machine room, a cinema and the like, the room must be separated from the outside by adopting a sound insulation wall body indoors, so that noise pollution is prevented from being generated to the outside or sound information is prevented from being leaked to the outside.
Traditional sound insulation wall body adopts thick type brick brickwork, multiple gypsum board wall, or thin type brick brickwork + multiple gypsum board wall structure more, and this kind of sound insulation wall body also can seriously increase sound insulation wall body's weight because of using the waste of wall brick and causing the resource and to the destruction of environment in a large number simultaneously. In addition, the gypsum board adopted by the sound insulation wall has higher requirement on the environment, and cannot be suitable for places with high environmental humidity.
The sound insulation wall of the combined structure adopting the light partition board and the double-layer fiber cement board to be respectively provided with the heat preservation part and the double-layer fiber cement board appears in the current market, and is disclosed as follows: CN 201721104376.2's a compound fire prevention wallboard and wall body, the utility model discloses a sound insulation wall body that discloses in this utility model can alleviate wall body weight, and have partial fire prevention, the sound-proof ability, but the sound insulation wall body of this kind of structure is simply with two fiber cement boards laminating together and constitutes a thickness for 12 mm's double-deck fiber cement board, it does not have the difference with thickness 12 mm's single-deck fiber cement board in function and structure, it belongs to this many with two fiber cement boards laminating into a double-deck fiber cement board, not only increased the panel cost, the construction complexity has still been increased simultaneously, be not as directly adopting the fiber cement board that the individual layer 12mm is thick to make the wall. In addition, rock wool is filled in the first space and the second space between the double-layer fiber cement board and the light partition board of the wall body, so that the double-layer fiber cement boards on the front side and the rear side are directly connected with the light partition board in the middle layer through the rock wool. It is known from the common knowledge that the transmission efficiency of sound waves in solids is far higher than that in air, so that the structural design of directly connecting the double-layer fiber cement board with the light partition board through rock wool without a cavity structure cannot completely block the transmission of sound waves, and the sound insulation effect is not ideal.

As can be seen from the common knowledge, the compactness of the rubber material is high, the separation effect to the sound wave is excellent, and the propagation velocity of the sound wave in the air is far less than the propagation velocity in the solid, therefore, the utility model discloses on the combined structure basis of the prefabricated sound insulation composite board layer 1 of double-deck fiber cement sheet layer 3 and 4 centre gripping of soundproof rock wool layer, add intermediate layer rubber pad 5 inside double-deck fiber cement sheet layer 3, add surface layer rubber pad 6 at both sides around the prefabricated sound insulation composite board, reduce the thickness of soundproof rock wool layer 4 simultaneously and make the cavity structure between double-deck fiber cement sheet layer 3 and the prefabricated sound insulation composite board layer 1, can effectively separate the sound wave, make the sound wave through the utility model discloses the sound wave of soundproof wall passes through double-deck fiber cement sheet layer 3, air, sound insulation layer 4, surface layer rubber pad 6, prefabricated sound insulation composite board layer 1 that have intermediate layer rock wool rubber pad 5 in proper order, Surface course rubber pad 6, soundproof rock wool layer 4, air and have double-deck fiber cement sheet layer 3 of intermediate layer rubber pad 5 weaken step by step until eliminating completely, have greatly improved the utility model discloses an effect gives sound insulation.
Additionally, the utility model discloses a dry operation worker method installation of assembled light wall body, the efficiency of construction is high, has improved the operating efficiency, has reduced the expenditure of cost of labor.
The above examples are merely for clarity of description of specific embodiments of the present invention and are not intended to limit the embodiments of the present invention. The foundation the utility model discloses the principle can be derived and summarized other some to adjustment or the change of double-deck fiber cement sheet layer 3, intermediate layer rubber pad 5, light gauge steel 2, soundproof rock wool layer 4, surface course rubber pad 6 and prefabricated compound sheet layer 1 that gives sound insulation, just not enumerate one by one here. Any modification, replacement or improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
