Detailed Description
The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, a partition wall with sound insulation effect according to an embodiment of the present invention includes a hollow wall body 1, and a sound insulation plate assembly located in a cavity of the wall body 1. The sound insulation board assembly comprises an upper sound insulation board 2 and a lower sound insulation board 3, the top end of the upper sound insulation board 2 is fixedly connected with the top end of the wall body 1, and a gap is reserved between the bottom end of the upper sound insulation board 2 and the bottom end of the wall body 1; the bottom end of the lower sound insulation board 3 is fixedly connected with the bottom end of the wall body 1, and a gap is reserved between the top end of the lower sound insulation board 3 and the top end of the wall body 1; the upper baffle plate 2 and the lower baffle plate 3 are arranged in a staggered manner. Both side surfaces of the upper baffle plate 2 and the lower baffle plate 3 are respectively in a wave shape.
In the partition wall of the above embodiment, a cavity is provided in the wall body 1, and a sound insulation plate assembly is provided in the cavity. Sound insulation is provided by the cavity and baffle assembly so that less sound passes through the partition outside the partition. Specifically, sound enters the cavity of the wall body 1 through one side of the wall body 1, and then the sound propagates through the upper baffle plate 2, the lower baffle plate 3, and the gap between the upper baffle plate 2 and the lower baffle plate 3. In the process, because a plurality of upper sound insulation boards 2, lower sound insulation boards 3 and gaps formed between the upper sound insulation boards and the lower sound insulation boards are arranged, the sound is gradually weakened in the transmission process, and finally, less sound passes through the other side of the wall body 1. When sound is transmitted to the upper baffle plate 2, most of the sound passes through the upper baffle plate 2, and a small part of the sound passes through a gap below the upper baffle plate 2. Both side surfaces of the upper baffle plate 2 and the lower baffle plate 3 are respectively in a wave shape. Since the sound is transmitted at different speeds in the air and the panel, and the upper baffle plate 2 has different thickness, and the distance between the upper baffle plate 2 and the lower baffle plate 3 is different, the sound simultaneously entering the cavity of the wall body 1 from the side of the wall body 1 passes through the upper baffle plate 2 to reach the lower baffle plate 3 at different times. Also, the lower baffle 3 has a different thickness, and a gap is provided above the lower baffle 3, so that sound passes through the lower baffle 3 to reach the next upper baffle 2 at a different time. In this way, the sound is attenuated gradually during propagation through different media and different propagation paths.
Preferably, in the overlapping portion of the two opposite side surfaces of the upper baffle plate 2 and the lower baffle plate 3, the top end of the convex portion of the upper baffle plate 2 and the top end of the convex portion of the lower baffle plate 3 are opposite to each other, and the bottom end of the concave portion of the upper baffle plate 2 and the bottom end of the concave portion of the lower baffle plate 3 are opposite to each other. The distance between the upper baffle plate 2 and the lower baffle plate 3 is different because both side surfaces of the upper baffle plate 2 and the lower baffle plate 3 are respectively wavy. The distance between the top end of the convex portion of the upper baffle plate 2 and the top end of the convex portion of the lower baffle plate 3 is smallest, and the distance between the bottom end of the concave portion of the upper baffle plate 2 and the bottom end of the concave portion of the lower baffle plate 3 is largest. Thus, the sound reaches the lower baffle plate 3 or the upper baffle plate 2 at different times with different propagation distances between the upper baffle plate 2 and the lower baffle plate 3. This facilitates noise reduction and silencing.
Preferably, the surfaces of the upper baffle plate 2 and the lower baffle plate 3 are respectively coated with sound-deadening layers. Sound enters from one side of the upper baffle plate 2 and exits from the other side of the upper baffle plate 2. The surface of the upper baffle plate 2 is coated with a sound-deadening layer so that sound is muffled both when entering and when exiting the upper baffle plate 2. Similarly, sound enters from one side of the lower baffle 3 and exits from the other side of the lower baffle 3. The surface of the lower sound insulation board 3 is coated with the sound-deadening layer, so that sound can be deadened when entering and transmitting out of the lower sound insulation board 3, and the sound-deadening effect is further improved.
As shown in fig. 2, it is preferable that the upper baffle plate 2 is arranged obliquely and the lower baffle plate 3 is arranged vertically. Lay last acoustic celotex board 2 slope for the distance between last acoustic celotex board 2 and the lower acoustic celotex board 3 increases gradually or reduces gradually from the top down on the vertical face, further changes the propagation distance of sound between last acoustic celotex board 2 and lower acoustic celotex board 3, makes sound arrive next acoustic celotex board with the time of difference, improves and goes up acoustic celotex board 2 and 3 noise cancelling effect of lower acoustic celotex board.
Preferably, there are two upper baffle plates 2 and two lower baffle plates 3. Since the volume of the cavity of the wall 1 is limited, too many upper and lower acoustic panels 2, 3 cannot be arranged in the wall 1. When the upper baffle-boards 2 and the lower baffle-boards 3 with too small number are arranged, the sound insulation effect of the whole partition wall is not good. Preferably, two upper soundproof plates 2 and two lower soundproof plates 3 are arranged, so that the soundproof effect of the partition wall is good, and the soundproof plates can be arranged in a limited space.
In order to further improve the noise reduction effect, it is preferable that the noise reduction plate 4 is arranged on the inner wall of the wall body 1. The silencing plate 4 is arranged on the inner wall of the cavity of the wall body 1, so that when sound is transmitted out of the wall body 1, the sound is further silenced, and the silencing effect is improved.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to further illustrate the principles of the utility model, and that various changes and modifications may be made without departing from the spirit and scope of the utility model, which is also intended to be covered by the appended claims. The scope of the utility model is defined by the claims and their equivalents.
