Description

Sound Absorbing Type Soundproofing Panel

The present invention relates to a sound absorbing soundproof panel that absorbs and attenuates noise generated from a road or a railway, and more particularly, predetermined irregularities in the sound absorbing material and the front plate to effectively absorb broadband composite noise including high frequency and low frequency noise. It relates to an additionally formed sound-absorbing soundproof panel.

Recently, as the roads and railways become faster, noises with wider frequency bands are generated. Soundproof walls are installed on the side of roads or railway lines to block noise generated from roads and railways. In general, a plurality of H-beam supports are installed on a foundation concrete at regular intervals, and a plurality of soundproof panels are provided between two adjacent supports. Install it by inserting it. The soundproof panel used in the soundproof wall has a soundproof soundproof panel that simply blocks the generated noise and a soundproof soundproof panel that absorbs and extinguishes the generated noise. However, soundproof soundproof panels having excellent soundproofing performance are mainly used for soundproof walls on roads or railroads. The present invention relates to such a sound absorbing soundproof panel.

1A and 1B are a perspective view and a cross-sectional view showing an example of a conventional sound absorbing soundproof panel. As shown in the figure, the biggest feature of the sound-absorbing soundproof panel 10 is that the sound-absorbing material 30 in the interior space formed by the front plate 20 and the back plate 22 formed with a plurality of sound absorbing holes 12 will be. Sound absorbing material 30 is made of a porous material such as glass wool, polyurethane foam, polyester wool and the like. In particular, the sound absorbing material made of glass wool may be blown glass powder, which may adversely affect the human body, and the sound absorbing material is deformed by rainwater, and thus the sound absorbing ability is greatly reduced.

It is known that the sound absorption rate of the flawless soundproof panel is mainly proportional to the thickness of the sound absorbing material 30. 2 is a graph showing a change in sound absorption rate with increasing frequency. As shown in the figure, reference numeral 2 shows a change in the sound absorption rate of a thick sound absorbing material (for example, 50 mm) and reference number 4 for a thin sound absorbing material (for example, 25 mm). That is, the highest sound absorption in the range of 300Hz to 800Hz, the thick sound absorbing material (2) exhibits a sound absorption rate of almost 100%, and the thin sound absorbing material (4) also exhibits a sound absorption of 70 to 80%. However, it can be seen that the absorption rate drops rapidly when the sound absorbing material is thin as well as when the sound absorbing material is thinner than 300 Hz and 800 Hz or more.

Therefore, in order to remove the noise centered on 500Hz, the sound absorption material can be thickened to achieve a sound absorption ratio close to 100% .However, in the soundproof walls of high-speed roads or high-speed railways where low-frequency noise and high-frequency noise are mixed below 300Hz and 1000Hz, The target value cannot be achieved only by thickening the sound absorbing material. In addition, the thicker the sound absorbing material, the thicker the sound insulation panel and the H beam, and the larger the cost and installation space. Therefore, the new type can eliminate the noise of broadband within the optimal sound absorbing material thickness considering the installation space and installation cost. The development of the flaw type soundproofing panel 6 is calculated | required.

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

Figure 3a is a perspective view showing an example of a sound-absorbing soundproof panel according to the present invention and 3b is a cross-sectional view showing the cross-sectional structure of the same parts as the prior art the same reference numerals are omitted.

First, FIG. 3A shows the front plate 20 of the sound absorbing soundproofing panel 1 according to the present invention. The front plate 20 is flat and a plurality of sound absorbing holes 12 are regularly drilled. And both sides are formed in each of the vertical coupling groove 16 is coupled to the front wing of the H-beam, the upper coupling portion 18 is formed bent along the longitudinal direction and the lower portion corresponding to the coupling protrusion 18 Grooves 19 are formed. Reference numeral 13 denotes a bent portion of the back plate 22.

In Figure 3b the sound absorbing material 30 according to the present invention is well shown. A plurality of sound absorbing material uneven parts 40 are formed on the front surface of the sound absorbing material 30 along the horizontal direction. As shown, the sound absorbing material 30 according to the present invention has the same thickness (a) or thicker than the existing sound absorbing material and at the same time the sound absorbing material uneven portion 40 having a constant protruding length (b) and width (c) And a plurality of recesses 42 and convex portions 44 are alternately repeated. For example, the sound absorbing material 30 according to the present invention may have a thickness a of 100 mm and a protruding length b and a width c of 50 mm, respectively. Therefore, in the sound absorbing soundproofing panel 1 according to the present invention, the surface area of the sound absorbing material 30 is widened by the sound absorbing material uneven portion 40, thereby increasing the noise removing efficiency. The protruding length b of the sound absorbing material uneven portion 40 has a relatively large length of about 3/2 to 1/3 of the total sound absorbing material thickness a, preferably about 1 to 1/2, and one sound absorbing material 30 ), Three to five, preferably four sound absorbing material irregularities 40 are formed.

On the other hand, the sound absorbing material uneven portion 40 according to the present invention can be selectively applied in various forms depending on the purpose of use and function. For example, FIG. 4A shows a sound absorbing soundproof panel having a semi-circular sound absorbing material uneven portion 40, FIG. 4B shows a sound absorbing sound absorbing panel having a trapezoidal sound absorbing material uneven portion 40, and FIG. 4 shows a sound absorbing soundproofing panel 1 having an inverted trapezoidal sound absorbing material uneven portion 40. FIG. In the case of the inverted trapezoidal sound absorbing material uneven portion 40, if the sound absorbing material uneven portion 40 and the sound absorbing material 30 is integrally manufactured, it is very difficult to assemble, so that the sound absorbing material uneven portion 40 and the sound absorbing material 30 separately It is preferable to prepare. In addition to this purpose, if the sound absorbing material 30 and the sound absorbing material uneven portion 40 are separated into separate members, the noise generated by vibrating the separated sound absorbing material uneven portions 40 consumes energy, thereby improving sound absorption. Therefore, as shown in the case of Figure 4c, it is also preferable to separate the sound absorbing material uneven portion 40 in several pieces. 4A and 4B, if the sound absorbing material 30 and the sound absorbing material uneven portion 40 are made of glass wool, it is necessary to wrap the polyvinyl film 32, but as shown in FIGS. 4C and 4D, the sound absorbing material uneven portion 40 is shown. ) Is made of polyurethane foam or polyester wool, it is possible to remove the polyvinyl film from the sound absorbing material uneven portion 40 can increase the efficiency of removing high frequency noise. That is, as is known, glass wool is easily deformed by rainwater, so it is inevitable to wrap it with a polyvinyl film. This polyvinyl film has a detrimental effect on removing high frequency noise.

In other words, as shown in the graph of Fig. 5, the polyester wool sound absorbing material 3 in the loose state has a superior ability to remove high frequency noise compared to the glass wool sound absorbing material 5 in the coated state, so that the sound absorbing material uneven portion 40 is removed. The sound absorbing material 7 according to the present invention made of a polyester wool in a loose state is to improve both the low and high frequency noise as well as the sound absorption rate for high frequency noise.

6A to 6D show a perspective view, an exploded perspective view and a cross-sectional view showing another embodiment of the sound absorbing soundproof panel according to the present invention, as shown in the figure, separated from the body 3 of the sound absorbing soundproofing panel 1. The front plate uneven portion 50 is formed on the front plate 20 as much as possible. That is, the sound absorbing soundproof panel 1 according to the present invention has a front plate 20 'having an open portion 7 formed thereon so that the sound absorbing material uneven portion 40 is exposed to the outside, and is fixed to the rear of the front plate 20'. The main body 3 of the sound-absorbing soundproof panel including a back plate 22 coupled to each other and a gap material 30 installed in the interior space, and is installed to close the opening 7 of the front plate and a plurality of front It consists of the front plate 20 in which the plate uneven part 50 was formed. The front plate 20 is a plate-like body in which a plurality of front plate concave-convex portions 50 are integrally bent, and a plurality of fastening holes 23 that can be fastened to the main body 3 of the sound-absorbing soundproof panel at both upper and lower ends thereof. Is formed, is coupled to the sound-absorbing soundproof panel body 3 through a separate fastening means (5). In the drawing, an embodiment of the front plate uneven portion 50 in which the square recess 52 and the convex portion 54 are alternately repeated is illustrated, and the front plate irregular portion 50 corresponds to the sound absorbing material uneven portion 40. Since the form is the same as the shape of the sound absorbing material uneven portion 40.

That is, the front plate 20 according to the present invention is made by bending a plurality of sound absorbing holes 12, the metal plate regularly perforated to form a plurality of front plate irregularities 50, the sound absorbing material uneven portion 40 In addition to the protective function, it also increases the mechanical strength of the front panel. In addition, the sound absorbing material uneven portion 40 according to the present embodiment may be integrally formed with the sound absorbing material 30 or may be separately formed and inserted into the front plate uneven portion 50.

In addition, the front plate 20 according to the present invention, as shown in Figure 5d, the sound absorption rate of the noise by integrally forming the side wall 21 formed with a plurality of sound absorbing holes 12 on both sides of the front plate uneven portion 50 Can be maximized.

On the other hand, another embodiment of the sound-absorbing soundproof panel according to the present invention, as shown in Figure 7a and 7b, a plurality of front plate concave-convex portion 50 is integrally bent to the back plate 22 Combined. This embodiment is similar to the embodiment described with reference to FIG. 6A except that the front plate 20 having the front plate uneven portion 50 integrally coupled to the back plate 22 is different.

Another embodiment of the sound absorbing soundproofing panel 1 according to the present invention is to have a plurality of sound absorbing material uneven portion 30 and the front plate uneven portion 50 having a different protruding length. As shown in FIGS. 8A and 8B, the sound absorbing soundproofing panel 1 has a sound absorbing material uneven portion 40 and a front plate uneven portion 50 whose protruding length is shortened from the top to the bottom. Therefore, the sound-absorbing soundproofing panel 1 has a shape in which the upper portion protrudes forward as a whole. As described above, the front plate 20 is inclined at a predetermined angle with respect to the ground, and when the front plate 20 is perpendicular to the traveling direction of the noise, the efficiency of absorbing the noise is increased.

In addition, the arrangement of the sound absorbing material uneven parts 40 and the front plate uneven parts 50 having different protruding lengths may be modified in various ways. FIGS. 9A and 9B illustrate uneven parts 40 having the longest protruding length. An embodiment in which 50) is positioned in the middle of the sound absorbing soundproofing panel 1 is shown. Accordingly, when the soundproof wall is installed as the soundproof panel 1, as shown in FIG. 10, a large number of large uneven parts are formed in the soundproof wall in the horizontal direction to effectively remove the complex noise mixed with noises of various frequencies.

Meanwhile, in the sound absorbing soundproof panel 1 according to the present invention, as shown in FIGS. 8A and 9A, vertical coupling grooves 16 are formed on both sides of the sound absorbing soundproof panel 1 in the vertical direction. Therefore, when the coupling groove 16 is inserted into the front wing portion 62 of the H beam 60 serving as a support, the sound absorbing soundproof panel 1 can be more easily laminated. That is, as shown in the schematic plan view shown in FIG. 11A, the sound absorbing material 40 and 50 are formed with the uneven parts 40 and 50 because the sound absorbing material 30 can be thickened regardless of the size of the H beam 60 serving as the support. Suitable for soundproof panel (1).

That is, as in the conventional method, when the sound-absorbing soundproof panel 1 is inserted into the groove of the H beam 60, the thickness of the sound absorbing material may be limited by the width of the H beam 60, but in the present invention When the sound insulation panel 1 is coupled to the front wing portion 62 of the H beam 60 as described above, the sound absorbing material 30 or the sound absorbing material uneven portion 40 can be further installed in front of the H beam front wing portion 62. .

On the other hand, when the sound-absorbing soundproof panel 1 is provided on the front wing portion 62 of the H-beam 60, a constant space 64 is formed between the neighboring sound-absorbing soundproof panel 1. The space 64 may be left as empty as shown in FIG. 10, but it is preferable to insert the coupling pad 70 as shown in FIG. 11A. The coupling pad 70 may have various pad uneven portions 72 according to the cross-sectional shape of the uneven portion 50 of the sound absorbing soundproofing panel 1. And the coupling pad 70 is made of a material having a porosity and cushioning to improve sound absorption and bonding.

And as shown in Figure 7a, when the vertical coupling groove 16 is not formed on the side of the sound-absorbing soundproof panel (1) is inserted between the grooves of the H beam 60 in the same manner as the conventional method is installed. . In this case, a predetermined gap may be formed between the rear surface of the front wing portion 62 of the H beam and the front plate 20 according to the shape of the uneven portion 50. Therefore, the noise may be transmitted to the rear surface of the soundproof wall through the gap, it is preferable to block through the coupling pad 80 as shown in Figure 12b. In addition, Figure 12c is a perspective view showing a coupling pad 90 of another form according to the present invention, which is, as in the case of Figure 6a, the uneven portion 40, 50 protrudes in front of the front wing portion 62 of the H beam Coupling pad 92 is applied to the case. That is, in the case of 5a, since the uneven parts 40 and 50 protrude in front of the front wing part 62 of the H beam, a relatively wide space 64 is generated between the adjacent sound absorbing soundproofing panels 1. Therefore, when the coupling pad 90 is installed in the space 64, the soundproofing efficiency is increased and the appearance of the soundproof wall is beautiful. Although the embodiments of the coupling pads of various forms have been described above, this is for explaining the technical idea of the present invention and those skilled in the art will be able to easily use other types of coupling pads similar thereto.

And the sound absorption rate of the sound-absorbing soundproof panel (1) (2) and the sound-absorbing soundproof panel according to the prior art according to the present invention was tested as a result, a graph as shown in FIG. This test was measured according to the test method of KS F 2805 (Measurement of Sound Absorption Rate in Reverberation Chamber, 1996). As a result of the test, the existing sound-absorbing soundproof panel showed a rapid drop in sound absorption rate below 300Hz and above 800Hz, but according to the present invention, the sound-absorbing soundproof panel 1 (specifically, a sound absorbing material having a different protrusion length and a front plate uneven portion) Sound-absorbing soundproof panel) showed a high sound absorption rate of about 80% even at 150Hz and 1000Hz, and exhibited a higher sound resistance than the conventional soundproof panel. In particular, the sound-absorbing soundproofing panel 2 (specifically, when the uneven portion of the sound absorbing material is made of a polyester wool in a loose state) exhibits a sound absorption rate of 80% or more even at 1500 Hz or higher, thereby absorbing noise in a low frequency band as well as a high frequency band. It is showing excellent ability.

As described above, the sound absorbing soundproof panel according to the present invention has an effect of effectively eliminating broadband noise by effectively absorbing low frequency and high frequency noise which have not been well removed in the past.

Therefore, the sound-absorbing soundproof panel according to the present invention is effective in removing complex noise in which various frequencies of noise are mixed, such as a high-speed road or a high-speed railway.

In addition, the sound-absorbing soundproof panel according to the present invention can be installed regardless of the thickness has the effect of saving the installation cost and space.

Sound-absorbing soundproof panel according to the present invention because the protrusion length of the uneven portion is different from each other, not only has the effect of removing the noise of various frequencies, but also can be variously obtained by selectively applying the arrangement of the uneven portion depending on the purpose and use.
