Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

For reference, for convenience of explanation, the up and down direction is indicated by the coordinate Z, the left and right directions by the coordinate X, and the coordinate Y in the front and rear directions.

As shown in FIG. 1, the soundproof panel according to an embodiment of the present invention has a stage 10b and has a front surface member 12, 14, and 16 having a plurality of hole surface side holes 10a formed therein. 10; And a sound absorbing member 20 installed at the rear of the front member 10 to absorb noise incident through the hole-side side holes 10a of the front member 10.

That is, noise is incident through the hole side side holes 10a of the front member 10, and the incident noise is absorbed by the sound absorbing performance of the sound absorbing member 20, so that sound insulation may be achieved.

In particular, the perforated surface 12, 14, 16 of the front member 10 is made of a concave-convex surface by the end (10b) rather than a plane, which can create the following effects.

First, the sound absorbing member 20 is positioned behind the pore surfaces 12, 14, and 16 of the front member 10, thereby providing a wide range of frequency bands through the plurality of pore surface side holes 10a of the front member 10. Since noise may be incident and absorbed into the sound absorbing member 20, the sound absorbing effect is excellent, and in particular, the sound absorbing effect is excellent for noise sources having a wide band frequency such as traffic noise of roads and railways.

Second, the distance between the air holes 12, 14, 16 of the front member 10 and the sound absorbing member 20 varies depending on the positions of the holes 10a of the front face 10 of the front member 10, and accordingly, a specific frequency. Noise of a wide frequency band is not limited to the noise of the band can be effectively incident through the hole side side hole (10a) of the front member 10 can be transmitted to the sound absorbing member (20).

In addition, since the noise may be reflected from the end 10b of the front member 10 toward the hole surface side hole 10a of the front member 10, the pore surfaces 12, 14, 16 of the front member 10. In addition to the noise directly incident on the), the noise of various incidence angles are effectively incident through the hole side side hole 10a of the front member 10, that is, the noise transmission amount to the sound absorbing member 20 is much higher.

Therefore, there are various variables such as vehicle type and traffic conditions, and the change of parameters is irregular, so that even if the frequency band of noise and the incident angle of noise vary from time to time, they can always fully respond to this, so as to maximize the sound absorption performance. Good sound absorption performance can be maintained at all times. And, accordingly, it can be installed anywhere without being restricted by the noise source.

Third, because the perforated surfaces 12, 14, and 16 of the front member 10 are uneven surfaces, the incidence noise can effectively enter the perforated side hole 10a of the front member 10. The sound absorption effect is also excellent.

Fourth, the perforated surface 12, 14, 16 of the front member 10 is formed as a concave-convex surface, the sound absorbing member 20 is formed in a plane, the space between the front member 10 and the sound absorbing member 20 (S) can be formed. Therefore, the sound absorption rate of the noise may be increased due to the space S described above, and thus an excellent sound absorption effect may be created.

Fifth, the stage 10b of the front member 10 serves as an auxiliary support, and thus, the stage 10b of the front member 10 shares the vertical stress, so that the structural stability of the soundproof panel can be increased. .

The front member 10 will be described in more detail as follows.

The front member 10 may be formed in a square as shown, and may be formed in various ways regardless of the shape of the triangle, pentagon, and the like.

The surface 12, 14, 16 of the front member 10 may be formed as long as the uneven surface, but the first hole formed with the hole side side holes (10a) so that the sound absorption effect is excellent without being too complicated The surface 12 and the hole-side side holes 10a are formed and may include a second hole surface 14 formed to be connected to the first hole surface 12 and the stage 10b.

The first and second pore surfaces 12 and 14 may be formed in various ways depending on the shape and the number thereof.

Preferably, the first pore surface 12 and the second pore surface 14 may be formed in the same (quad) square shape so as not to be too complicated or monotonous as shown.

A plurality of first and second pore surfaces 12 and 14 may be formed, respectively.

The first pore surface 12 and the second pore surface 14 may be arranged in various structures. In particular, as shown in the figure, the pore surfaces 12 and 14 of the front member 10 are divided into nine and the second pore surfaces are respectively disposed on the top, bottom, left, and right sides of the first pore surface 12 positioned at the center of the front member 10. 14 are positioned one by one, and the first pore surface 12 may be located at the remaining four corners, respectively.

Here, the step heights H1 and H2 of the plurality of second hole surfaces 14 may all be the same, but as shown, the plurality of second hole surfaces 14 may have a step with respect to the first hole surface 12. The formation of the plurality of pairs 14a and 14b according to the heights H1 and H2 may be more effective in that the noise of a wider frequency band and various incident angles can be absorbed. In addition, preferably, the plurality of second pore surfaces 14 may be divided into two groups 14a and 14b in order to maximize the sound absorbing effect without being too complicated or monotonous.

On the other hand, it is more effective that the second porous surface 14 is intaglio so as to protrude toward the rear of the front member 10 as follows.

That is, in the latter case, when the second perforated surface 14 is formed in an intaglio, it may be more preferable in that the finishing part and the airtight performance can be improved when installing the soundproof panel according to the present invention between the posts, that is, the H beam. .

On the other hand, as shown in Figure 6, in order to further diversify the type of the hole surface (12, 14, 16) of the front member 10, the hole surface (12, 14, 16) of the front member 10 It is formed in contact with one of the first hole surface 12 and the second hole surface 14 and the end (10b) so as to project toward the front member 10 forward with respect to the first hole surface 12, the hole The surface side holes 10a may further include a third porous surface 16 formed therein.

In addition, the front member 10 is formed around the perforated surface (12, 14, 16) of the front member 10, a plurality of ribs (18a) protruding toward the front member 10 in front of the edge portion 18 It may further include. In this case, the plurality of ribs 18a may be reinforced with the front member 10, so that structural safety may be increased. In addition, noise may be more diffusely reflected and canceled out by the plurality of ribs 18a, so that the sound absorbing effect may be further improved.

Furthermore, the edge portion 18 may have at least some of the surfaces between the ribs 18a open to form the edge side hole 18b. Accordingly, noise may also be incident through the edge side hole 18b, and noise of a wider frequency band and various incident angles may be incident and absorbed by the sound absorbing member 20.

At this time, the edge side holes 18b are formed only at the edge portions 18e and 18f positioned on the left and right sides of the pore surfaces 12, 14 and 16 of the front member 10, and the hole surface 12 of the front member 10. The edge portions 18c and 18d positioned above and below the surfaces 14 and 16 are formed between the ribs 18a so that the fitting portion 32 of the rear member 30 to be described later may be covered by the front member 10. May not be opened.

And, the edge portion (18c, 18d) located above and below the pore surface (12, 14, 16) of the front member 10 is a fitting groove that can be fitted to the fitting portion 32 of the back member 30 to be described later 18g, it may be formed such that the erase portion 18h is located behind. That is, the deleted portion 18h is an unnecessary portion, whereby the weight of the front member 10 can be relatively light, and the manufacturing cost of the front member 10 can be reduced.

The hole surface side holes 10a of each of the hole surfaces 12, 14, and 16 of the front member 10 may be formed in the same size and shape, or may be formed in various sizes and shapes according to the main noise source. .

The front member 10 may be formed of various materials, more preferably, plastic or similar materials.

The sound absorbing member 10 will be described in more detail as follows.

The sound absorbing member 20 may be any material and shape as long as the sound absorbing member 20 can absorb noise, and may be preferably formed of a porous material.

Hereinafter, in the present invention, the material or structure of the sound absorbing member 20 is not necessarily limited to a specific one, and the material or structure of the sound absorbing member 20 for sound absorption is known a lot, and further detailed description thereof will be omitted. .

In addition, the sound absorbing member 20 may be relatively weak in durability and easily contaminated due to material characteristics, and the sound absorbing member 20 may be protected by the back member 30.

The back member 30 may be formed of various materials, and in particular, may be formed of a steel sheet to reinforce the soundproof panel.

The back member 30 may be formed in various ways according to the binding method with the front member 10, in particular it may be coupled to the front member 10 in a slide (slide) manner as shown. That is, the fitting member 32 is formed at the upper and lower ends of the rear member 30, respectively, and the edge portions 18c and 18d are positioned at the upper and lower sides of the pore surfaces 12, 14 and 16 of the front member 10, respectively. In order to couple the rear member 30 and the front member 10, a fitting groove 18g may be formed to allow the fitting portion 32 of the rear member 30 to be fitted along the left and right directions.

The back member 30 may be formed in a unidirectional structure such that only one front member 10 may be bound as shown in FIG. 2A, and as shown in FIG. 2B, the back member 30 may be formed on both sides of the back member 30. Each of the front member 10 may be formed in a bidirectional structure so that the binding.
