Description

Novel sound-absorbing wall

Technical Field

The utility model relates to an interior decoration technical field, concretely relates to novel sound absorbing wall.

Background

At present, the common sound absorbing panel wall scheme mainly includes two kinds: the other is that the sound-absorbing board is directly arranged outside the steel keel and the base layer of the wood board, the keel base layer is firstly arranged, sound-absorbing cotton is filled between the keel base layer and the wall surface, and then the sound-absorbing board is arranged. The two construction methods are simple and convenient to operate, low in construction cost and high in construction speed, but the sound absorption effect is poor, and particularly for spaces with special purposes, such as the trial court of the people's court, the sound absorption requirement of the spaces is high, and the requirements on the sound absorption effect cannot be met through the traditional sound absorption plate wall construction method. In this case, if the sound absorption effect is to be improved, the thickness or density of the material is often selected to be increased, which, however, also increases the construction cost virtually.

SUMMERY OF THE UTILITY MODEL

The above-mentioned not enough to prior art exists, the utility model aims to provide a novel sound absorbing wall to solve among the prior art high-efficient sound absorbing wall material thickness or the great, the higher problem of cost of density of inhaling.

Solve the technical problem, the utility model discloses a following technical scheme:

a novel sound-absorbing wall comprises a wall body, a plurality of keel blocks, a plurality of keel strips and sound-absorbing boards. The keel blocks are distributed on the wall at intervals and fixedly connected with the wall, and a space is reserved between every two adjacent keel blocks. And a layer of metal wire mesh is laid on one side of the keel block, which is far away from the wall body, and the metal wire mesh is fixedly connected with the wall body through a screw penetrating through the keel block, so that a gap is formed between the metal wire mesh and the wall body. The keel strips are respectively transversely and longitudinally crossed and arranged on one side, deviating from the keel blocks, of the wire mesh, and are fixedly connected with the keel blocks through screws, the keel strips transversely and longitudinally arranged are combined to form a plurality of rectangular grids, and the rectangular grids are filled with sound absorption cotton. The sound cloth is inhaled to the one deck laid in the outside of fossil fragments strip, inhale the sound cloth and cover fossil fragments strip and inhale the sound cotton completely to link to each other fixedly through screw and fossil fragments strip. The sound absorption board is laid on the outer side of the sound absorption cloth, completely covers the sound absorption cloth and is fixedly connected with the wall body through screws.

Preferably, the keel block is located at the intersection of the horizontally arranged keel strip and the longitudinally arranged keel strip, or at the center of the horizontally arranged keel strip, and is fixedly connected with the corresponding keel strip.

Preferably, the sound-absorbing cotton outside in each rectangular grid is also provided with a sound-absorbing material layer, and the sound-absorbing material layer is fixedly connected with the sound-absorbing cotton.

Preferably, the surfaces of the keel blocks and the keel strips are coated with fireproof coatings.

Preferably, the wire mesh is a galvanized wire mesh.

Preferably, the sound-absorbing plate is a holey wood sound-absorbing plate.

Compared with the prior art, the utility model has the advantages of as follows:

novel inhale the sound wall in be provided with the clearance between sound cotton and the wall body, make and inhale the vacuole formation between sound cotton and the wall body, utilize cavity resonance structure can obtain the biggest acoustic absorption coefficient, inhale the sound cotton and be zero from the acoustic pressure of wall 1/4 wavelength portion, the vibration speed of air particle is the biggest, it is also the biggest to inhale the acoustic energy of the friction damping loss that the sound cotton played, makes sound-absorbing material produce the biggest sound absorption effect to promote the sound absorption effect of inhaling the sound partition wall.

Drawings

Fig. 1 is the utility model relates to a novel sound absorbing wall's schematic structure diagram.

In the figure: wall body 1, fossil fragments piece 2, wire mesh 3, clearance 4, fossil fragments strip 5, inhale sound cloth 6, abatvoix 7.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

A novel sound-absorbing wall comprises a wall body, a plurality of keel blocks 2, a plurality of keel strips 5 and a sound-absorbing plate 7. The keel blocks are distributed on the wall body 1 at intervals and fixedly connected with the wall body, and a space is reserved between every two adjacent keel blocks. And a layer of metal wire mesh 3 is laid on one side of the keel block, which is far away from the wall body, and the metal wire mesh is fixedly connected with the wall body through a screw penetrating through the keel block, so that a gap 4 is formed between the metal wire mesh and the wall body.

The keel strip is transversely and longitudinally crossed and arranged on one side, deviating from the keel block, of the wire mesh, and is fixedly connected with the keel block through screws, wherein part of the keel block is positioned at the crossed part of the transversely arranged keel strip and the longitudinally arranged keel strip and is fixedly connected with the keel strip through screws. The other part of the keel block is positioned in the center of the transversely arranged keel strip and is fixedly connected with the keel strip through a screw, and the keel strip is separated from the wall body through the thickness of the keel block, so that a certain distance is reserved between the keel strip and the wall body. And the keel strip combination of horizontal and vertical setting forms a plurality of rectangle net the rectangle net intussuseption is filled with and inhales the sound cotton, inhales the cotton packing thickness of sound and is unanimous with the thickness of keel strip, because the cotton packing of inhaling of stopping of wire mesh and sound, makes clearance 4 become the cavity structure that is used for resonating, and when the degree of depth of this cavity is greater than 1/4 sound wave wavelength odd number times, can produce the biggest sound effect of inhaling. Wherein, the cotton outside of inhaling the sound in every rectangle net still is equipped with the one deck and inhales the sound material layer, inhale the sound material layer and inhale the cotton fixed linking to each other of sound, can advance to promote and inhale the sound effect. The outer side of the keel strip is laid with a layer of sound absorption cloth 6, the keel strip and the sound absorption cotton are completely covered by the sound absorption cloth, and the sound absorption cloth is fixedly connected with the keel strip through screws. The sound absorption board 7 is laid on the outer side of the sound absorption cloth, completely covers the sound absorption cloth, and is fixedly connected with a wall body through screws.

In specific implementation, the surfaces of the keel blocks and the keel strips are coated with fireproof coatings. The metal wire mesh is a galvanized metal wire mesh. The sound-absorbing board is a perforated wood sound-absorbing board, and the porosity of the perforated wood sound-absorbing board is 15% -30%.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the technical solutions, and those skilled in the art should understand that those modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all should be covered in the scope of the claims of the present invention.
