Description

{SOUND PROOF TUNNEL STRUCTURE}

[0001] The present invention relates to a soundproof tunnel structure, which prevents rainwater from flowing into the interior of the soundproof tunnel structure, prevents moisture from flowing into the interior of the soundproof tunnel structure, Structure.

This provides an excellent leak prevention effect and improves the service life of the soundproofing tunnel and maintains the airtightness even after the soundproofing tunnel is assembled.

Generally, a soundproof tunnel is constructed in the shape of a tunnel, and is installed on a large road adjacent to a downtown area or a residential area, thereby blocking the noise of the vehicle generated on the road.

Therefore, both side and top of the road are completely sealed so that the noise generated from the road is not leaked to the outside, and since the sound-absorbing tunnel absorbs the noise, the driving noise affecting the driver is also reduced, It is in fact installed.

Such a soundproof tunnel is exposed to the surrounding environment such as snow and rain because it has a tunnel shape surrounding the upper and both sides of the road as described above. Since the soundproof tunnel is an assembling structure, it is a gap between the assembling members constituting the soundproof tunnel, There is a very high risk of corrosion due to foreign matter.

Therefore, as a conventional technique for solving such a problem, Korean Patent Registration No. 10-1849173 describes an "arch type prefabricated tunnel type soundproofing board having a waterproof function ".

In the prior art, in forming an arched tunnel-type sound insulation panel by laminating a sound-absorbing panel including a top bar and a bottom panel assembled on the upper and lower sides of the transparent plate, the curved surface portion of the H- A middle bar and a middle bar are assembled so that the tunnel type sound insulation plate is kept in an arcuate shape so that the upper bar and the middle bar and the middle bar and the middle bar are not introduced into the middle bar and the middle bar, To a tunnel type sound insulation plate having an additional waterproof function.

However, even if the middle bar 200 and the heavy bar 400 are overlapped with each other, a clearance between the middle bar and the hub bar is necessarily generated in the overlapped portion, and the upper bar 300 and the middle bar 200 The gasket 300 and the middle bar 200 are provided with gaskets provided at the ends thereof to prevent the gap between the upper and lower ends of the transparent plate 120 and the transparent plate 120. [ There is a high possibility of being damaged due to foreign substances impregnated into the inside.

In this case, the gasket is made of a thin synthetic resin material, which is rapidly deteriorated when it comes in contact with foreign matter such as rainwater, so that the gasket and the transparent plate are not closely adhered to each other and the airtightness is remarkably deteriorated. When the gasket is exposed to sunlight, And the life of the soundproof tunnel is further shortened.

Particularly, there is an inconvenience that the soundproof tunnels are difficult to partly replace the damaged parts in the replacement and maintenance work, and the maintenance work becomes large.

Therefore, it is necessary to prevent rainwater or the like from flowing into the sound-absorbing tunnel structure that is assembled so that the sound-absorbing tunnel can be used for a long period of time, and to prevent the gasket from being rapidly aged due to the sunlight. It is necessary to develop a soundproof tunnel structure that can maintain the airtightness of a soundproof tunnel structure.

Further, the lower surface 20a of the frame 20 is provided with a sanding machine It is possible to further increase the frictional force by performing the sanding process.

Such a frame 20 can improve the bonding force with a structure such as a beam to be coupled later through the lower surface 20a.

The frame 20 having a rectangular shape is manufactured in a large size because it forms a soundproof tunnel. Since the soundproof panel 10 and the cover 30 are provided on the upper side of the frame 20, There is a problem that the frame 20 is bent due to a load.

Therefore, in order to solve such a problem, it is possible to manufacture a frame 20 having an inner wall or the like supporting the upper and lower surfaces so as to distribute the load inside the frame 20, but if the internal structure is large or has a complicated shape, .

In the present invention, the coupling member 50 is connected to upper surfaces of both sides from the center of the upper surface of the frame 20 through which the coupling member 50 is coupled, and connected to the lower center of the frame 20, A dispersing frame 24 is provided.

[

Meanwhile, the cover 30 may be made of aluminum but is not limited thereto.

As described above, the leakage preventing tucks 21 and 31 are provided to prevent the inflow of rainwater or the like to the gasket 40 side of the frame 20 and the cover 30, .

The water leakage preventing tails 21 and 31 are formed at both ends of the frame 20 and the cover 30 and are formed on the lower surface of the cover 30 and the first leakage preventing tuck 21 formed on the upper surface of the frame 20 And a second waterproofing jig 31 which is made of a waterproof material. The first and second water leakage preventing tails 21 and 31 serve to prevent the gasket 40, which is inwardly spaced from each other, from preventing water leakage and blocking sunlight.

The first water leakage preventing jaw 21 is formed by protruding a predetermined length from the upper end side of the frame 20 to the upper side, that is, the side where the soundproofing plate 10 is located, And is protruded by a predetermined length from the lower surface side toward the lower side toward the sound insulation plate 10 side.

Therefore, the water leakage preventing jig prevents foreign substances from entering the space in the space where the frame 20 and the cover 30 are separated from the soundproof panel 10, and acts as an abatement film from external direct sunlight that is exposed toward the gasket 40 Can be performed.

It is possible to prevent rainwater from being leaked primarily by directly blocking the rainwater flowing from the outside through the water leakage preventing tails 21 and 31 and to prevent direct sunlight from being directly applied to the gasket 40, Thereby minimizing denaturation and enabling long-term use.

The gasket 40 is spaced apart from the water leakage preventing tails 21 and 31 by a predetermined distance and spaced grooves 21a and 31a are formed between the water leakage preventing tails 21 and 31 and the gasket 40. [ That is, a gap between the first leakage preventing tuck 21 formed in the frame 20 and the first gasket coupling opening 22, the second leakage preventing tuck 31 formed in the cover 30, and the second gasket coupling opening 32, The spaced apart grooves 21a and 31a are formed.

These spacing grooves 21a and 31a can not move the rainwater flowing into the gasket 40 beyond the water leakage preventing tails 21 and 31 toward the gasket 40. The rainwater flowing into the gap grooves 21a and 31a, .

Since the rainwater flowing into the gasket 40 side is small, the introduced rainwater is not moved to the side of the gasket 40 beyond the gasket coupling openings 22 and 32, but is accumulated in the spacing grooves 21a and 31a, Leakage of the tunnel structure can be prevented.

The sound insulation board 10 coupled to the frame 20 and the cover 30 is provided with a gasket 40 spaced apart from the leakage preventing tails 21 and 31 for improving the airtightness.

However, when the gasket 40 is coupled with the cover 30 and the frame 20 and the sound insulation plate 10, the gasket 40 may be displaced from the initial installation position by an external force, The gasket coupling holes 22 and 32 are formed at positions where the gasket coupling parts 22 and 32 are coupled with each other.

The gasket coupling holes 22 and 32 are formed in the frame 20 and the cover 30, respectively, and are formed as a pair, and the gasket 40 is inserted and coupled to the inside. The gasket fittings 22 and 32 are provided in the frame 20 and include a first gasket coupling hole 22 protruding upward to locate the soundproofing plate 10, And a second gasket coupling 32 protruding downward.

The gasket 40 is brought into close contact with the upper and lower surfaces of the frame 20 and the soundproof plate 10 joined between the cover 30 and the frame 20 to prevent water from flowing into the center of the frame 20 and the cover 30 To improve confidentiality.

The gasket 40 is composed of an upper gasket 40 coupled with the cover 30 and a lower gasket 40 coupled with the frame 20. The upper gasket 40 and the lower gasket 40 are coupled to each other when the frame 20 and the cover are engaged with each other and the soundproof plate 10 is positioned between the upper gasket 40 and the lower gasket 40, .

The gasket 40 is made of an elastic material such as rubber and tightly coupled to the sound insulation board 10 positioned between the gaskets 40. The gasket 40 has a close contact surface 40a It is possible to prevent the sliding of the soundproofing plate 10 in a form in which the soundproofing plate 10 is in close contact with the flat surface of the soundproofing plate 10 and to prevent the thickness of the soundproofing plate 10 from exceeding the upper and lower gaskets 40, , The corrugated surface of the contact surface 40a is compressed and bent so that the soundproof plate 10 is brought into close contact with the gasket 40 to maintain airtightness.

The upper gasket 40 is provided on both sides of the lower surface of the cover 30 and the lower gasket 40 is provided on the upper surface of the frame 20. The soundproof panel 10 is positioned between the upper gasket 40 and the lower gasket 40 and is in close contact with the soundproof panel 10 assembled with the cover 30 and the frame 20 so that the cover 30 and the frame 20 It is possible to prevent the rainwater from flowing into the center side of the rainwater.

The gasket fittings 22 and 32 have a shape in which a pair of projections protrude from the side of the soundproof plate 10. The gasket 40 is fitted to the inner side of the gasket fittings 22 and 32 so that the gasket fittings 22 and 32 are simply fitted The gasket 40 may be separated from the gasket fittings 22 and 32 in the assembling process so that the gasket 40 may be formed in another embodiment so as to improve the bonding force between the gasket 40 and the gasket fittings 22 and 32 .

This will be described with reference to FIG. 3 attached hereto.

First, a surface of the gasket (40) opposite to the contact surface (40a) is formed with a gasket locking protrusion (41) formed by being recessed toward the inside of the gasket (40).

The gasket engaging protrusions 22a and 32a projecting toward the gasket 40 side are formed at positions corresponding to the recessed surfaces of the gasket 40 to correspond to the gasket engaging protrusions 41 so that the gasket engaging protrusions 41 are caught.

Therefore, the gasket engagement grooves 22 and 32 and the gasket engagement grooves 22a and 32a have a concave shape and are engaged with each other so that the gasket 40 can not be easily separated from the gasket engagement grooves 22 and 32.

The engaging member 50 is coupled to the frame 20 through the cover 30 and through the frame 20 and the cover 30 to the side of the soundproof plate 10 provided between the frame 20 and the cover 30. [ So that the interval between the soundproof plate 10 and the soundproof plate 10 can be minimized.

This engaging member 50 is coupled through the cover 30 and the frame 20 using a screw bolt and is used as another embodiment of the engaging member 50 as shown in Fig. A nut 51 is additionally provided at the end of the engaging member 50 penetrating into the frame 20 and the nut 51 is engaged with the engaging member 50. At this time, It is possible to prevent the nut 51 from hanging on the side of the center frame 23 even if the engaging member 50 moves upward due to external force because the diameter is larger than the width of the drawn-in central frame 23.

As shown in FIG. 4, after the assembly of the above-mentioned soundproof tunnel structure is completed, a separate sealing operation is performed for each gap to prevent a gap between the leakage preventing tails 21 and 31 and the soundproofing plate 10, Closing.

In other words, both the clearance generated between the frame 20 and the soundproofing plate 10 and the clearance generated between the cover 30 and the soundproofing plate 10 are treated with the sealing material 70 to block rainwater or the like flowing from the outside.

Therefore, the soundproof tunnel structure having the above-described structure prevents the inflow of rainwater to the inside, and the water introduced into the inside also naturally dries without moving to the inside, thereby preventing damage to the soundproof tunnel structure due to leakage of water. This has the effect of improving the service life.

1 to 4 described above only describe the essential matters of the present invention. As various designs can be made within the technical scope of the present invention, the present invention is not limited to the configurations of Figs. 1 to 4 It is self-evident.
