The most commonly used structure of the sound insulation wallboard in the prior art is a solid-air-solid structure, namely, when sound waves enter a first layer of material in a solid and are transmitted to an air layer, the air layer can generate elastic deformation to play a role in shock absorption, so that the vibration transmitted to a second layer of material is greatly weakened, and the total sound insulation quantity of the structure is improved. However, when the frequency of the incident sound wave is equal to the resonance frequency of the system, the sound insulation structure has almost no sound insulation effect, so that a porous sound absorption material or a damping material is required to be filled in the two interlayers to inhibit the vibration of the panel, the sound insulation amount during resonance is improved, the porous sound absorption material has the sound absorption performance, and the two materials are matched to form the sound insulation solid-porous damping-sound insulation solid structure.

The sound insulation solid-porous damping-sound insulation solid structure is widely used in airplanes and factories, but the sound insulation solid structure is not researched to be used for sound insulation of a taxi room, and the sound insulation wallboard is usually a whole board, so that the taxi room is difficult to mount and dismount, high in cost and low in practicability.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiment of the present invention, all other embodiments obtained by the person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1, the utility model provides a multilayer composite construction's sound insulation wallboard, fine board, steel sheet 3 and screw 4 in fire-retardant.

The fire-retardant well fibreboard has bellied fire-retardant well fibreboard mainboard 1, two fire-retardant well fibreboard curb plates 2 to constitute by the soundproof surface of upper portion along direction of height both sides, and the fibreboard curb plate 2 is located the both sides of fire-retardant well fibreboard mainboard 1 respectively in fire-retardant, and 2 highly shortages of fire-retardant well fibreboard mainboard 1 of fire-retardant well fibreboard curb plate in fire-retardant, and three fire-retardant well fibreboards are all stood on ground, and wherein, the fibre board mainboard 1 does not have bellied one side and stands on ground in fire-retardant.

Because the people's activity region is usually on ground or near ground, and the noise mainly comes from low frequency noise such as speech, writing, these low frequency noise incident wave angle, the wavelength range is all unfixed, although steel sheet 1 areal density is great, but when certain sound wave rather than producing "resonance", give sound insulation failure, and fibre board is porous material in the fire-retardant, and the absorption effect to the low frequency noise is better, consequently, fibre board in the fire-retardant well fibre board of multilayer composite construction's sound insulation wallboard lower part of this embodiment is three-layer, and is thicker, the low frequency noise such as speech, writing that fine isolation people's activity region produced. The noise of the upper part in the room mainly comes from an air conditioner, the noise of the air conditioner has stable audio frequency and incident angle, and the steel plate can avoid resonance only by reasonably adjusting the thickness of the steel plate, so that the steel plate can achieve the aim of sound insulation, and the upper steel plate layer is thicker and the flame-retardant medium density fiberboard is thinner.

In addition, three fire-retardant medium density fiberboard forms the domes, plays the supporting role to whole multilayer composite construction's sound insulation wallboard. And the flame-retardant medium density fiberboard is divided into three parts, so that the installation, the production and the transportation are convenient.

The two steel plates 3 are in an axe shape, the axe part is provided with a groove corresponding to the size of the protrusion on the main board 1 of the flame-retardant medium density fiberboard, and the two steel plates 3 are embedded with the flame-retardant medium density fiberboard. The axe body part of the steel plate 3 is provided with a hole, and the screw 4 penetrates through the steel plate from the hole and is fixed in the flame-retardant medium density fiberboard side plate 2 to fix the steel plate 3. It should be noted that the screws 4 cannot be driven into the fire-retardant medium density fiberboard main board 1 because the screws cannot be driven vertically into the fire-retardant medium density fiberboard due to resistance, and if the screws are driven into the fire-retardant medium density fiberboard main board 1, they may touch each other, so that a "sound bridge" is formed between the two steel plates 1, and the sound insulation effect disappears.

Sound exists with the form of ripples, and steel sheet 1 because surface density is very big, reflection sound wave that consequently can be fine, but still have partial sound wave because the particularity of incident wave angle and wavelength can pierce through steel sheet 1 and reach fire-retardant well fibreboard 2, fibreboard 2 is porous structure in fire-retardant, because the sound wave propagates with the form of energy, and the sound wave makes a round trip reflection energy in the fire-retardant well fibreboard 2 course of walking and exhausts, reaches the mesh that gives sound insulation.

As shown in fig. 2, the utility model discloses during the installation, earlier with in fire-retardant fiberboard mainboard 1 and two fire-retardant fiberboard curb plates 2 pieces together, the place that fiberboard mainboard 1 and fire-retardant well fiberboard curb plate 2 link to each other can have the gum in fire-retardant, bonds during the use, makes it more firm, installs two steel sheets 1 again, goes up well screw 4 at last. Several parts can be installed separately, so that compared with integral installation, each part has lighter weight, and common households can independently install the parts without professional persons.

Example 2

The difference between this embodiment and embodiment 1 is that a slope is disposed on the axe of the axe-shaped structure of the steel plate 1 on the side away from the groove, and a sound insulation felt 5 is adhered to the slope, where the sound insulation felt 5 is a triangular body and has a size corresponding to the slope. Because the indoor air conditioner has certain noise, and the air conditioner is located room upper portion, if the air conditioner noise is reflected back on steel sheet 1, easily reflect to rest areas such as floor, desk, influence the resident family and have a rest on the contrary, consequently, paste the felt on steel sheet 1 upper portion, absorb the air conditioner noise, do not propagate to next door promptly, prevent again that the sound wave reflection from influencing the resident family oneself.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention is not limited by the appended claims.
