Description

Novel sound insulation wall

Technical Field

The utility model relates to a building technical field that gives sound insulation specifically is a novel sound-proof wall.

Background

In a building with high noise of a machine or an environment with special requirements on sound, a sound insulation chamber is required to be arranged as a space for a few of people who perform precise operation or mental labor, and external noise is isolated or the noise in the sound insulation chamber is prevented from being transmitted to the outside, so that the inner side or the outside is prevented from being disturbed by the noise.

The sound insulation effect of the wall body of the sound insulation room in the prior art is not good, so that the sound insulation effect of the whole sound insulation room is poor, and the higher requirements of people on the sound insulation room cannot be met.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome current defect, provide a novel sound-proof wall, promote syllable-dividing effect greatly, the equipment is the sound insulation effect of whole promotion soundproof room behind the soundproof room.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel sound insulation wall, includes steel sheet, first wall body, sound absorbing layer, second wall body and interior wall sound absorbing layer, novel sound insulation wall has set gradually steel sheet, first wall body, sound absorbing layer, second wall body, interior wall sound absorbing layer from extroversion-in, steel sheet and first wall body fixed connection, be provided with the sound absorbing layer between first wall body and the second wall body, second wall body and interior wall sound absorbing layer fixed connection.

Furthermore, the steel sheet outside is provided with the spraying plastics layer, further gives sound insulation.

Further, the thickness of the steel plate is 1.0-2.0 cm.

Furthermore, the sound absorption layer and the inner wall sound absorption layer are made of soundproof cotton.

Furthermore, the middle of the sound absorption layer is divided into two parts with the same thickness through a sound insulation plate which is vertically arranged.

Furthermore, glass magnesium boards are fixedly arranged on the outer sides of the first wall body and the second wall body.

Furthermore, the thickness of the glass magnesium plate is 0.4-1.0 cm.

Compared with the prior art, the beneficial effects of the utility model are that: this type sound-proof wall has following benefit:

1. the sound insulation wall considers the isolation of sound, and simultaneously, the energy consumption process of the sound in the transmission process is very important, and a high-performance sound absorption energy consumption layer is arranged in the sound insulation wall to control the consumption of sound energy to the maximum.

2. The sound insulation wall is small in thickness and large in sound insulation amount, the sound insulation effect is guaranteed, meanwhile, the space is saved to the greatest extent, and the area of the operation audiometric environment is improved.

Drawings

Fig. 1 is a schematic sectional structure of the present invention;

fig. 2 is a schematic cross-sectional view of an embodiment of the present invention;

fig. 3 is a graph of acoustic energy blocking loss according to the present invention.

In the figure: 1 spraying plastics layer, 2 steel sheets, 3 first wall bodies, 4 sound-absorbing layers, 5 second wall bodies, 6 inner wall sound-absorbing layers and 7 sound-insulating plates.

Detailed Description

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

Referring to fig. 1-2, the present invention provides a technical solution:

example 1:

as shown in fig. 1, a novel sound insulation wall, including steel sheet 2, first wall body 3, sound absorbing layer 4, second wall body 5 and interior wall sound absorbing layer 6, novel sound insulation wall has set gradually steel sheet 2, first wall body 3, sound absorbing layer 4, second wall body 5, interior wall sound absorbing layer 6 from the extroversion in, steel sheet 2 and first wall body 3 fixed connection are provided with sound absorbing layer 4 between first wall body 3 and the second wall body 5, second wall body 5 and interior wall sound absorbing layer 6 fixed connection.

The plastic spraying layer 1 is arranged on the outer side of the steel plate 2, and further sound insulation is achieved; the thickness of the steel plate 2 is 1.0-2.0cm, and in actual construction, the sound insulation effect and the cost are reasonably selected.

The sound absorbing layer 4 and the inner wall sound absorbing layer 6 are made of soundproof cotton, and the soundproof cotton is good in sound absorbing effect and low in cost.

Example 2:

this example differs from example 1 in that:

in this embodiment, as shown in fig. 2, the sound absorbing layer 4 is divided into two parts having the same thickness by the sound insulating plate 7 vertically disposed, and the sound insulating plate 7 refracts and reflects sound waves to enhance the sound insulating effect.

The outer sides of the first wall body 3 and the second wall body 5 are fixedly provided with glass magnesium boards, the thickness of each glass magnesium board is 0.4-1.0cm, and the glass magnesium boards refract and reflect sound waves to enhance the sound insulation effect.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
