Description

【Technical field】
[0001]
The present invention relates to an integrated plastic soundproof panel. More specifically, the soundproof panel can be easily and easily installed to attenuate noise, and each connecting portion is not exposed to the outside so that a beautiful appearance can be obtained. Since each soundproof panel assembled in multiple layers has an independent soundproof room configuration in a closed state, it can completely attenuate low frequency fine noise, and foreign matter that has flowed into the soundproof panel can be removed. The present invention relates to an integrated soundproofing panel that can be discharged and can reduce costs by molding the soundproofing panel with a single injection.
[Background]
[0002]
In general, a soundproof panel is used to absorb, disperse, and extinguish noise, and is mainly installed in places where noise prevention is necessary, such as schools, hospitals, and houses adjacent to roads.
Noise, which is a by-product of industrial development, is inevitably increased due to the increase in various types of vehicles and machinery. With the emergence of environmental problems, soundproof panels have been developed to achieve this goal.
[0003]
On the other hand, as shown in FIGS. 1a and 1b, the conventional sound insulation panel has an end portion of each sound insulation panel 10 on a support frame 1 made of an H beam erected by a fixing means (not shown) such as an anchor bolt. Then, another fixed body 2 is placed between the support frame 1 and the soundproof panel 10 or the thickness of the built-in sound absorbing material is increased as shown in FIG. The thickness is increased and slidably coupled to the support frame 1 so that the shielding mold 12 formed integrally with the end portion of the soundproof panel 10 surrounds the support frame 1 and is not exposed to the outside.
[0004]
However, in the case of the conventional soundproof panel as described above, in the case of the former (FIG. 1a), in order to install the soundproof panel, a separate fixing body is always required, so that the installation work is complicated and a firm connection is required. In addition, since the support frame and the fixed body are exposed to the outside, not only the appearance is not beautiful, but also the sound insulation panel has a small thickness, and therefore there is a drawback that the sound insulation, that is, the noise removal rate is lowered.
[0005]
In the latter case (FIG. 1b), the support frame exposed to the outside is shielded by the shielding piece integrally formed with the soundproof panel, and the appearance is improved. However, the protrusion protrudes to shield the support frame. Due to the shielding piece, other aesthetic problems occurred.
[0006]
In addition, most of the conventional soundproof panels use aluminum outer walls, but this aluminum is damaged by weak external force because the strength of the outer walls is not enough, and if it is oxidatively corroded after installation, it will become dirty and discolored and road environment It becomes an impediment factor. In addition, the soundproof panel made of aluminum is not only reduced in the soundproof performance due to the looseness of the assembly parts generated by the vibration of the vehicle or the train after the construction, but also the built-in glass fiber. Sound absorbing materials such as those that are wet or scattered in the rain cause very bad results in terms of the environment, and have recently been identified and restricted as carcinogens in relation to the human body.

[0022]
9a, 9b, and 9c are partial cross-sectional views showing a usage state of the soundproof panel according to the present invention.
In FIG. 9A, soundproof panels 100 are coupled to both sides of a support frame 101 made of an upright H beam, and tension pieces 112 of a fixed body 110 are fixed to the inner surface of the support frame 101 by pressing force and frictional force. The outer surface of the frame 101 is surrounded by the front seat 102 and the rear seat 104 of the main body 120 and joined so as not to be exposed to the outside. FIG. 9B shows the soundproof panel 100 formed on both side surfaces of the main body 120. The tension pieces 112 of the fixed body 110 are connected to the support frame 101 in close contact with each other, and each of the soundproof panels 100 is connected by a connecting pipe 128 formed on the bottom surface.
[0023]
At this time, since the tension piece 112 of the fixed body 110 is pressure-bonded by the support frame 101, it is firmly supported and fixed with a constant repulsive force.
[0024]
FIG. 9c shows a state in which the soundproof panel is installed in a curved shape using a cylindrical support frame. When the soundproof panel 100 is to be installed in the curved shape, a cylindrical support frame 101 is installed. Thereafter, a coupling recess 114 having a predetermined radius formed on the fixed body 110 is coupled to the soundproof panel 100.
[0025]
The operation and effect of the present invention will be described as follows.
As shown in FIGS. 2 to 9 c, a large number of tension pieces 112 protrude in the vertical direction at both end portions of the front seat 102 and the rear seat 104 of the main body 110 at a predetermined interval along the central axis. A fixed body 110 having an arcuate coupling recess 114 having a radius of 1 is formed integrally, and a number of linear protrusions 122 and suction holes 124 are formed in the front seat 102 at regular intervals. The upper and lower surfaces are inclined by a predetermined angle θ ₁ , θ ₂ , the shielding piece 126 is bent downward at the lower end, a number of connecting pipes 128 protrude downward at the bottom, and a partition plate is provided inside the main body 120. 142 divides the first, second and third sound absorbing chambers 134, 136 and 138, the bottom surface forms a bottom plate 144 having a constant angle θ ₃ , the cover 150 is coupled to the upper surface of the main body 120, and the front seat 1 02 is formed with a discharge hole 106, the upper surface of the connecting pipe 128 is closed, and is integrally connected by a rib 128 ', and has a predetermined radius along the central axis at both side ends of the main body 120. In order to install the soundproof panel 100 in which the coupling recess 114 is formed in a school, hospital, house, etc. adjacent to the road, where noise prevention is necessary, first, the structure (not shown) already installed is installed. Support frames 101 made of H beams are installed at regular intervals.
[0026]
When the soundproof panel 100 is coupled between the support frames 101 in this state, the installation of the soundproof panel 100 for soundproofing is completed. At this time, the soundproof panel 100 coupled to the support frame 101 is firmly supported and fixed by the tension pieces 112 of the fixing body 110 formed on both side surfaces of the main body 120, and the soundproof panel 100 is supported by the front seat 102 and the rear seat 104. The support frame 101 to be coupled is surrounded so as not to be exposed to the outside.
[0027]
As described above, after the soundproof panel 100 is coupled to the support frame 101, a number of soundproof panels 100 (determined by the height of the soundproof panel to be installed) are connected in the vertical direction by the above-described method. Sano soundproof panel is completed. The soundproof panel 100 and the soundproof panel 100 are connected to each other by a connecting pipe 128 provided on the bottom surface, and are partitioned by the ribs 128 ′ formed in the connecting pipe 128 by the inside of each soundproof panel 100, that is, by a partition plate 142. The first, second, and third sound absorbing chambers 134, 136, and 138 are closed to have independent sound absorbing spaces, and a cover 150 for internal closing is provided on the upper surface of the soundproof panel 100 located at the uppermost end. Combined.
[0028]
Accordingly, the second sound-absorbing chamber 136 into which the sound-absorbing material 132 is inserted and the first and third sound-absorbing chambers 134 and 138 having a certain width A are defined by the partition plate 142 of the main body 120 of the sound-proof panel 100 and the front. Noise flowing into the suction hole 124 formed in the sheet 102 is attenuated.
The noise flowing in through the suction hole 124 passes through the first sound absorbing chamber 134 and is firstly absorbed and dispersed by the sound absorbing material 132 inserted into the second sound absorbing chamber 136, and the noise that has not been removed first is the sound absorbing material. After passing through 132, it flows into the third sound absorbing chamber 138, is reflected by the inner wall, flows into the sound absorbing material 132, and is secondarily absorbed (absorbed and dispersed). Since the noise that has not been removed by the primary and secondary sound absorption is in a state where the soundproof panel 100 is sealed, the soundproof panel 100 is not propagated to the outside, and thus the inside of the main body 120, that is, the first, second, and third sound absorption chambers 134. Since reflection, absorption, and dispersion are repeated within 136, 138, not only high frequency high sounds but also low frequency fine noises are absorbed and dispersed to achieve complete sound insulation.
[0029]
Further, when noise flows into the first sound absorbing chamber 134 through the suction hole 124 formed in the front seat 102, a large number of linear protrusions 122 protruding at equal intervals on the outer surface of the front seat 102 have a predetermined angle θ _1. , Θ ₂ (see FIG. 8), the noise flowing in from the upper and lower sides is smoothly guided and flows into the suction hole 124 along the inclined surface.
[0030]
And since the shielding piece 126 protrudes downward at the lower end portion of the front sheet 102 of the soundproof panel 100 that is stacked and connected in the vertical direction so as to have a certain height, the connection portion is blocked and the overall appearance is blocked. While improving, the noise by the clearance of a connection part can be attenuate | damped completely.
Noise due to such a gap is completely attenuated by the ribs 128 ′ formed on the connecting pipe 128 on the bottom surface of the main body 120 of the soundproof panel 100, and is firmly supported and fixed.
[0031]
On the other hand, if various foreign matters, dusts, etc. flow in through the suction holes 124 formed in the front seat 102 due to wind or rain and accumulate in the main body 120, particularly in the first sound absorbing chamber 134, a long period of time elapses. At the same time, the sound absorption efficiency decreases due to foreign matter, dust, and the like. By the way, in the soundproof panel 100 according to the present invention, as shown in FIG. 7, the bottom surface 144 of the main body 120 is formed with a bottom plate 144 having a predetermined angle θ ₃ , and the discharge hole 106 is formed at the lower end of the front seat 102. Foreign matter, dust, or rainwater that has flowed in through the suction hole 124 flows along the bottom plate 144 without being accumulated or accumulated inside, and is discharged to the outside through the discharge hole 106. Therefore, it is possible to prevent such a drawback that the sound absorption efficiency due to the foreign matter and dust is reduced or corroded, and the soundproofing effect can always be exhibited in a clean state.
[0032]
Here, it is preferable that the angle θ ₁ of the linear protrusion 122 suitable for noise flow into the suction hole 124 is 20 to 30 °, and θ ₂ is 5 to 10 °. The angle θ ₃ of the bottom plate 144 formed on the bottom surface of the main body 120 is 2 to 10 °, and the width A of the first and third sound absorbing chambers 134 and 138 is 5 to 10 cm. Sound absorption effect is obtained.
[0033]
When the soundproof panel 100 is installed in a bending place such as a road, as shown in FIG. 9A, if a cylindrical support frame 101 ′ is used instead of the support frame 101 made of an H beam, the soundproof panel can be simply bent. 100 can be installed. That is, since the coupling recess 114 having a predetermined radius is formed along the central axis of the fixed body 110 formed in the main body 120 of the soundproof panel 100, the support frame 101 is installed by the connection recess 114 when the soundproof panel 100 is installed. The soundproof panel 100 can be installed in a bent form.
[0034]
Such a soundproof panel 100 is installed not only for a place where noise prevention is necessary, such as a school, a hospital, and a house adjacent to the road, but also for attenuating the noise inside the factory and inside the railway station.
[Industrial applicability]
[0035]
As described above, the integrated soundproof panel according to the present invention is simple and easy to install and install the soundproof panel, improves durability and robustness, and the connection part with the support frame is not exposed to the outside at all. A beautiful appearance can be displayed, and each laminated soundproof panel forms an independent soundproof room, so that high sound noise, low sound noise and noise caused by gaps are attenuated, enabling complete sound insulation treatment At the same time, dust flowing in from the outside can be discharged, so that clean soundproofing can be achieved. In addition, since the soundproof panel is formed by integral single injection, the manufacturing cost can be reduced and there is an economic effect.
