The present invention relates to a frame for a soundproof panel, and in particular, a plurality of sound absorbing grooves and protrusions are formed in the sidewall frame to significantly reduce driving noise and to improve reinforcement. It is about a dragon frame.

In general, noise generated from roads or general railways has a relatively constant level of noise as the speed of the noise source is within 100 ~ 130km / hr, but high-speed railways do not have typical high frequency characteristics due to high speed driving within 250 ~ 500km / hr. Since other types of noise are generated, it causes a lot of damages and influences on the surrounding private houses and livestock farms in remote areas, which is a serious problem.

Accordingly, concrete structures are installed at the boundary of roads and railways, and pillars such as H beams are installed at regular intervals on the concrete structures, and soundproof panels are laminated and installed on the pillars to block or hinder vehicle noise. Doing.

The sound insulation panel is coupled to a separate frame and installed.

Therefore, not only the soundproofing panel but also the frame supporting the soundproofing plate are exposed to vehicle noise, so that a frame capable of reducing noise is required, and the rigidity of the frame supporting the soundproofing plate is required. In addition, the frame is required to be able to stably support the soundproof plate vibrating by the influence of outside air, such as wind.

As an example of the existing soundproofing panel frame, as disclosed in the Korean Utility Model Registration No. 20-0452954 "frame for soundproofing plates" and shown in Figures 1 and 2, the insertion groove 14 is inserted into the soundproofing plate in one direction. And a base frame 10 having a second and third reinforcing grooves 11 and 13 and a second reinforcing protrusion 12 extending vertically from both sides of the base frame 10 and having an insertion groove 14. The side wall frame 20 in which the plurality of sound absorbing grooves 21 are formed in a direction corresponding to the length direction is disposed to face the base frame 10, and connects the side wall frame 20 to the longitudinal direction of the insertion groove 14. The groove 33 is formed in a direction corresponding to the first reinforcement groove 31 and the first reinforcement projection 32 is formed on the surface of the groove 33 is provided with a reinforcement frame (30).

The insertion groove 14 has a first reinforcing portion 15 having a width smaller than W1 and a second reinforcing portion having a width smaller than that of the first reinforcing portion 15 when the width of the inlet is W1. It has a portion 16.

The coupling method of the soundproof plate 3 and the frame 100 has a coupling structure that is integrally coupled by the sealing material 4 after the edge portion of the soundproof plate 3 is inserted into the insertion groove 14.

Subsequently, the frame 100 to which the sound insulation board 3 is coupled is disposed to be coupled to the H beam 2, which is a post arranged at regular intervals on the concrete structure 1.

Side wall frame 20 has a sound absorbing groove 21 is formed horizontally to diffract the vehicle noise to reduce the noise.

However, the prior art described above has a plurality of sound absorbing grooves formed in the side wall frame, but is simply formed in a horizontal groove shape, which does not have a significant effect on reinforcement and noise reduction.

The present invention was devised to solve this problem in view of the above-mentioned problems, and an object thereof is to provide a frame for a soundproof panel having an improved sidewall frame structure to greatly reduce noise and increase reinforcement.

3 to 7, the sound insulation panel frame 100 according to the first embodiment of the present invention has a space 105 formed therein, and an edge portion of the sound insulation panel 3 is inserted. A base frame 110 having an insertion groove 112 formed therein; A plurality of protrusions 122a extending vertically from both side surfaces of the base frame 110 and protruding at a predetermined interval inward and outward so that a plurality of sound absorbing grooves 124 and 134 are formed on the outer circumferential surface of the space 105. 122b) first and second side wall frames 120 and 130 on which 132a and 132b are formed; The support frame 140 is disposed opposite the base frame 110 to connect the first and second side wall frames 120 and 130, and a coupling groove 142 is formed at one center thereof to which another sound insulation panel frame is coupled. );

In more detail, the first and second side wall frames 120 and 130 are disposed to face each other and are spaced apart from each other, and the plurality of sound absorbing grooves 124 and 134 and the protrusions 122a and 122b and 132a and 132b are disposed. Is formed in the form of unevenness.

Here, the second side wall frame 130 is a side wall frame disposed at a position close to the road or railway side, and the first side wall frame is a side wall frame disposed outside the road or railway.

The protrusions 122a and 122b and 132a and 132b extend in the horizontal direction to the inside and the outside of the first and second side wall frames 120 and 130, respectively, and the inner protrusions 122a and 132a and the outer protrusions ( 122b) and 132b.

The base frame 110 is formed in the longitudinal direction at a position where the plurality of first reinforcing grooves 115a, 115b, 115c, and 115d and the second reinforcing grooves 116a and 116b are spaced apart from each other on the surface, that is, the inner and outer surfaces thereof. .

This is to reinforce the overall rigidity of the base frame 110.

In addition, the base frame 110 is formed with an insertion groove 112 recessed toward the space portion 105 so that the edge of the soundproof panel 3 is inserted in the center.

The insertion grooves 112 are formed with first and second stepped portions 112a and 112b, the width of which is narrowed toward the space 105.

Since the insertion groove 112 has an inlet width wider than that of the sound insulation panel 3, the edge of the sound insulation panel 3 actually contacts the first stepped portion 112a or the second stepped portion 112b. The sound insulation panel 3 is supported.

For this reason, it is applicable also to the soundproofing panel 3 of which width differs.

In addition, the support frame 140 has a coupling groove 142 recessed toward the space portion 105 at the center thereof, and a plurality of third reinforcing grooves 144a and 144b on inner and outer surfaces of the coupling groove 142. 144c and fourth reinforcing grooves 142a, 142b, 142c, and 142d are formed.

On the other hand, Figures 8 and 9 is a view showing another example of the frame 100 for a sound insulation panel according to the present embodiment, in addition to the components of the previous embodiment in the corner of the coupling groove 142 of the support frame 140 Coupling protrusion 145 is formed to be inserted into the coupling groove 142 of the frame 100 for another soundproof panel.

That is, when the sound insulation panel frame 100 is stacked up and down, the coupling groove 142 and the coupling protrusion 145 are fitted to each other to be coupled to each other.

10 is a view showing another example of the frame 100 for a sound insulation panel according to the present embodiment, the protrusions (122a, 122b) (132a, 132b) of the first and second side wall frames (120, 130) The thickness is differently formed to reinforce the inner protrusions (122a) (132a).

This indicates that the shapes of the outer protrusions 122b and 132b and the inner protrusions 122a and 132a may be formed differently.

In the first embodiment of such a configuration, first, a plurality of struts (H beams) are vertically installed in a concrete structure 1 installed at a road or railway boundary. In this embodiment, the H beam 2 is used as the support.

Thereafter, the sound insulation panels 3, each of which has a frame coupled to each edge thereof, are coupled between the H beams 2 adjacent to each other. At this time, the frame coupled to the side edge of the soundproof panel 3 is coupled to be fitted between both flanges of the H beam (2).

Meanwhile, when the sound insulation panel 3 and the frame 100 are coupled to each other by inserting the edge of the sound insulation panel 3 into the insertion groove 112, the edge of the sound insulation panel 3 is formed by the first stepped portion 112a or the first step. The second stepped portion 112b is coupled while being in surface contact.

Frame 100 is arranged in the form of a wall of a plurality of stacked on the boundary of the road or rail and arranged left and right.

For example, as illustrated in FIG. 15, the upper and lower laminated structures of the frame 100 are referred to as the upper frame 100 and the lower frame 100A positioned below the upper frame 100. The coupling protrusion 145 of the lower frame is fitted into the coupling groove 142 corresponding to the upper side and the lower frame has a coupling structure in which the upper frame and the lower frame are coupled to each other through the coupling groove 142 and the coupling protrusion 145. .

At this time, the second side wall frame 130 of the frame 100 is disposed on the side of the road or railway, and the sound absorbing groove is formed due to the configuration of the protrusions 132a and 132b and the sound absorbing groove 134 formed in the second side wall frame 130. The interference is reduced or eliminated due to the interference between the incoming noise and the reflected noise.

Therefore, the noise generated from the road or the rail can significantly reduce the noise generated from the road or the rail due to the interference of the sound generated through the sound absorbing groove 134.

[Second Embodiment]

Referring to FIG. 11, a plurality of protrusions 135 are formed on the inner circumference of the sound absorbing groove 134 of the second side wall frame 130 to protrude in a rounded shape to cancel noise transmitted from the outside. A through hole 136 is formed in the second side wall frame 130 to communicate the inside and the outside of the space 105.

The protrusion 135 is formed to extend in the longitudinal direction of the side wall frame, and is to assist the interference action of the fluid (air with noise) introduced through the sound absorbing groove 134.

Here, the protrusion 135 is shown to be formed only in the second side wall frame 130, it is also applicable to the first side wall frame 120.

This can significantly increase the noise reduction efficiency.

The through hole 136 is formed so that the noise introduced along the passage inside the sound absorbing groove 134 of the second side wall frame 130 flows into the space 105, and a part of the noise is in the space 105. By dissipating, the noise attenuation efficiency can be improved.

The rest of the components are the same as in the first embodiment, so detailed description thereof will be omitted.

[Third Embodiment]

Referring to FIG. 12, the protrusion 135 is formed differently among the components of the second embodiment, and the diameter of the through hole 136 is formed to be wider toward the outer side of the inlet from the space 105.

Since the protrusion 135 of the present embodiment is formed on the inner circumferential surface of the sound absorbing groove 134 rather than a plurality of protrusions 135 rounded toward the middle of the sound absorbing groove 134 in a convex shape, the shape of the protrusion 135 It may be formed differently from the previous embodiment and the fluid flowing from the inlet side of the sound absorbing groove 134 can be easily introduced into the sound absorbing groove 134.

In addition, since the projection 135 of the present embodiment is formed in a shape in which the width of the sound absorbing groove 134 is narrowed in the middle, the noise introduced into the sound absorbing groove 134 is quickly flowed through the internal passage of the Bernoulli. As it is introduced through the through hole 136 and the inlet side diameter of the through hole 136 is enlarged, the noise passing through the sound absorbing groove 134 can be easily introduced into the space 105.

Therefore, the noise passes through the sound absorbing groove 134 to smoothly flow into the interior of the space 105 to be effectively extinguished.

[Fourth Embodiment]

13 and 14, in addition to the components of the previous embodiment, the protrusions 132a and 132b of the second side wall frame 130 are formed to be inclined downward toward the outside.

The protrusion 135 of the double inner protrusion 132a may be canceled in the space 105 after the noise smoothly flows into the space 105.

This is because the noise generated when the vehicle running on the road or railway as shown in FIG. 15 is transmitted diagonally from the lower side to the upper side, thereby smoothly introducing the noise into the sound absorbing groove 134, and conversely into the sound absorbing groove 134. By matching the discharge direction of the reflected noise with the inflow direction of the noise, it is possible to effectively cancel the noise due to the noise interference phenomenon.

In addition, since the protrusion 132b is formed to be inclined downward, it is possible to prevent foreign matters such as dust from accumulating in the sound absorbing groove 134 and to smoothly clean the foreign matter in the sound absorbing groove 134.

Embodiments of the present invention as described above may increase the reinforcement by forming protrusions inward and outward on the first and second side wall frames 120 and 130, and as the protrusions 135 and the through holes 136 are formed. It has the advantage of increasing the noise reduction effect.
