It is possible to safely perform work regardless of the installed position of the soundproof wall (1).

The transparent sound insulation plate 301 fixed between the plurality of frames 302 is securely fixed between the plurality of frames 302 by an elastic member 306 inserted into at least one of the plurality of frames 302. The elastic member 306 is compressed by the transparent sound insulation plate 301 when the transparent sound insulation plate 301 is inserted between the plurality of frames 302.

5 is a view showing the diffraction of noise in the side frame of the noise induction type sound insulation panel shown in FIG. 4. Referring to FIG. 5, the noise induction type soundproof panel 3 introduces noise generated from the front into the frame of the noise induction type soundproof panel 3.

The plurality of noise induction protrusions 4011 guide the noise generated from the front of the sound insulation panel 3 to the inlet 4012 of the noise induction block 401. Each noise induction protrusion 4011 protrudes in the same direction as the normal line of the noise induction block 401 having an arc-shaped cross section.

6 is a view showing a process in which noise is guided to an inlet in the noise induction block shown in FIG. 4.

As described above, the noise induction protrusion 4011 of the noise induction block 401 protrudes in the same direction as the normal line of the arc. The noise induction protrusion 4011 protrudes above a predetermined height from the arc of the noise induction block 401 and extends in the longitudinal direction of the noise induction block 401. Noise generated from a noise source located in front of the noise induction type soundproof panel 3 proceeds toward the noise induction type soundproof panel 3 in various directions. As the noise induction protrusion 4011 protrudes in the same direction as the arc normal, the noise proceeding toward the noise induction type sound insulation panel 3 when reflected after collision with the noise induction protrusion 4011 is two adjacent noise induction protrusions. (4011) is reflected inward. The noise proceeds toward the inlet 4012 formed in the center between the adjacent two noise inducing protrusions 4011 while repeating collision and reflection between the adjacent two noise inducing protrusions 4011.

As described above, as the noise induction protrusion 4011 protrudes in the same direction as the arc normal, the noise proceeding toward the noise induction type sound insulation panel 3 is 2 adjacent when reflected from the noise induction protrusion 4011 The noise is reflected between the two noise inducing protrusions 4011, and by repeating collision and reflection between the two adjacent noise inducing protrusions 4011, the noise is guided to the inlet 4012 formed between the two adjacent noise inducing protrusions 4011. .

The noise introduced into the frame 302 is reduced in magnitude according to the Helmholtz resonator principle. Noise passing through the inlet 4012 having a narrow cross-sectional area flows into the frame 302 having a large volume, and a resonance phenomenon occurs therein, so that the amount of noise in the frame 302 is reduced.

As described above, the noise induction type sound insulation panel 3 according to the embodiments of the present invention includes a left frame 3023 and a right frame 3024 each having a noise induction block 401. Each noise induction block 401 is detachably attached to each of the frame body 403 and the support block 402 by screwing at least one bolt 308. The noise induction type sound insulation panel 3 is a frame body 403 and noise induction block 401 of the left frame 3023 and the right frame 3024 after the transparent sound insulation panel 301 is separated from the plurality of frames 302 The noise induction block 401 may be removed from the left frame 3023 and the right frame 3024 by loosening the screwing of the bolt 308 between them.

As described above, without separating the noise induction type sound insulation panel 3 from the H-beam post 2, screwing of the bolt 308 between the noise induction block 401 and the frame body 403 and the noise induction block ( The noise induction block 401 is detached from the left frame 3023 and the right frame 3024 by holding the screw connection of the bolt 308 between the 401 and the support block 402. As such, the noise induction type sound insulation panel 3 according to the embodiments of the present invention includes at least one noise induction type sound insulation panel 3 stacked between adjacent two H-beam posts 2 and the H-beam post 2 It is possible to separate only the damaged noise induction block 401 from the noise induction type sound insulation panel 3 without separating from it. Accordingly, when the noise induction block 401 of some of the noise induction type sound insulation panels 3 is damaged, the noise induction block 401 is damaged without the need to separate the noise induction type sound insulation panel 3 from the H-beam post 2 ), since it can be removed and replaced, the maintenance and repair work of the noise-inducing soundproof panel 3 becomes very easy.

7 is a diagram illustrating a process of inducing noise to an inlet in a noise induction block according to another embodiment. According to another embodiment of the present invention shown in FIG. 7, the noise induction protrusion 4011 of the noise induction block 401 has a wider width of the noise induction protrusion 4011 as the distance from the arc of the noise induction block 401 increases. All. When the width of the noise inducing protrusion 4011 increases as the distance from the arc increases, the impacted noise is effectively transmitted to the inlet 4012 formed between the adjacent two noise inducing protrusions 4011 than the noise inducing protrusion 4011 having the same width. To induce. In the case of the noise inducing protrusion 4011 having the same width, the angle between the noise inducing protrusion 4011 and the plane in contact with the arc of the noise inducing block 401 is 90°, and the width of the noise inducing protrusion 4011 is gradually widened. In the case of loss, the angle between the noise induction protrusion 4011 and the plane in contact with the arc of the noise induction block 401 is less than 90°. As described above, as the angle between the noise induction block 401 and the plane becomes smaller, the noise that collides with the noise induction block 401 is not emitted to the outside of the two adjacent noise induction protrusions 4011 but is reflected inward. Accordingly, as the width of the noise inducing protrusion 4011 increases as the width of the noise inducing protrusion 4011 increases, the noise may be more effectively induced to the inlet 4012 formed between the two adjacent noise inducing protrusions 4011.

8 is a view showing the flow of noise in the frame of the noise induction type sound insulation panel shown in FIG. More specifically, it is a view showing the noise flowing into the frame 302 through the inlet 4012 formed in each of the left frame 3023 and the right frame 3024, the noise introduced into the frame 302. Referring to FIG. 8, noise introduced into the frame 302 flows to the upper frame 3021 and the lower frame 3022 where the inlet 4012 is not formed. The noise flowing inside the frame 302 collides with the inner surface of the frame 302 inside the frame 302 and repeats reflection from the inner surface, thereby reducing the size of the noise. The amount of noise is attenuated and extinguished while repeating collisions and reflections within the frame 302.

The plurality of frames 302 of the noise induction type sound insulation panel 3 according to another embodiment of the present invention has a sound absorbing material that absorbs noise inside. As described above, the noise generated from the front of the sound insulation wall 1 flows into the frame 302 through the inlet 4012 of the noise induction type sound insulation panel 3, and repeats collision and reflection within the frame 302. do. A sound absorbing material for absorbing noise may be attached to the inner surface of the frame 302 of the straight pipe shape. Here, the sound-absorbing material includes a porous sound-absorbing material, a plate-shaped sound-absorbing material, and a wedge-shaped sound-absorbing material, and may be made of urethane, rubber, polyester, or the like. Since the sound absorbing material is attached to the inner surface of the frame 302, the amount of noise flowing in the frame 302 is more efficiently attenuated. Accordingly, the noise blocking effect of the sound insulation wall 1 can be further improved.

As described above, the noise induction type sound insulation panel according to the embodiments of the present invention guides the noise generated from the front of the sound insulation wall to the inlet by using the noise induction protrusion of the noise induction block attached to the frame, thereby directing the noise into the frame. To induce. The noise induced into the frame is repeatedly collided and reflected in the frame, so that the noise level is continuously reduced and the noise disappears. Accordingly, the noise blocking effect of the soundproof panel can be improved.

In addition, the noise induction type sound insulation panel according to an embodiment of the present invention more effectively induces noise proceeding toward the noise induction type sound insulation panel as the width of the noise induction protrusion increases as the noise induction protrusion is further away from the arc-shaped noise induction block. Lead to the inlet of the block. As the width of the noise inducing protrusion gradually widens, the noise colliding with the noise inducing protrusion is not reflected outside of the adjacent two noise inducing protrusions, but is reflected inside the two adjacent noise inducing protrusions. As the width of the noise inducing protrusion gradually widens, the noise proceeding toward the soundproof panel is not emitted to the outside, and can be effectively guided to the inlet formed between the adjacent two noise inducing protrusions. As the noise is more effectively guided to the inlet, a large amount of noise is introduced into the frame and the noise is eliminated from the frame, thereby increasing the noise blocking effect of the soundproof panel.

In addition, when the noise induction block is damaged, the noise induction type soundproof panel is not separated from the H-beam post, and the screw connection between the noise induction block and the frame body and support block is loosened to induce noise. It can be separated from the soundproof panel. As described above, when the noise induction block of some of the noise induction type sound insulation panels is damaged, the noise induction type sound insulation panel can be separated and replaced without having to separate the noise induction type from the H-beam post. The maintenance and repair work of the soundproof panel becomes very easy. Accordingly, it is possible to save the maintenance and repair work cost of the noise induction type sound insulation panel, and prevent safety accidents that may occur during the replacement work of the noise induction type sound insulation panel in advance.

In addition, the noise induction type sound insulation panel according to the embodiments of the present invention can be easily separated by fixing the transparent sound insulation plate by using a fixing block that is detachable to the frame. The noise induction type sound insulation panel can easily separate the transparent sound insulation plate from the frame by separating the fixed block combined with the frame from the frame and pushing up the transparent sound insulation plate. The noise induction type sound insulation panel easily separates the transparent sound insulation plate from the frame in the above-described manner, so that the operator can easily and simply replace the transparent sound insulation plate when the transparent sound insulation plate is damaged or becomes dirty with contaminants. Accordingly, it is possible to reduce the cost of maintaining and repairing the soundproof wall, and to prevent safety accidents that may occur during replacement work.

In addition, the noise induction type sound insulation panel according to the embodiments of the present invention includes a sliding bump for preventing damage to the fixed block fixing the transparent sound insulation plate between the frames and the connection between the fixed block and the frame. The sliding bump can prevent the fixed block from being damaged or the coupling between the fixed block and the frame due to the load of the transparent soundproof plate. As the coupling between the fixed block and the frame is broken, a safety accident in which the transparent soundproof plate fixed between the frames falls can be prevented in advance.
