Description

Soundproof plate having the condition of being watertight by the shape to prevent sound leakage}

The present invention relates to a soundproofing panel installed between frames of a soundproofing wall as a component of a soundproofing wall or soundproofing tunnel installed around noise generating areas such as roads, railways, factories, etc. In the soundproofing board that is disposed across both ends between the frames and is laminated in the longitudinal direction of the frame to form a soundproof wall or soundproof tunnel, a gap occurs at the joint where several soundproof boards to be laminated are connected to each other, causing rainwater to leak or It relates to a sound insulation board having a watertight sound leakage prevention structure for preventing noise from leaking.

In order to block noise generated from roads, railways, factories, etc., soundproofing facilities are installed around them. These soundproof facilities can be largely divided into soundproof walls and soundproof tunnels.

In general, the soundproof wall is continuously arranged along the road with the frame erected upright in the form of a wall, and the soundproofing plate is placed across both ends between the frame and the frame and is continuously stacked in the longitudinal direction of the frame. In addition, the soundproof tunnel is formed by erecting the walls of the soundproof wall in two rows and adding a roof frame and a roof soundproof plate that connects the upper ends of the walls of the soundproof wall at an angle.

These soundproof walls and soundproof tunnels have a problem in that noise or rainwater leaks due to gaps occurring at joints where soundproof plates are connected to each other. When noise leaks from a soundproof wall or a soundproof tunnel, the effectiveness of soundproof facilities installed to prevent noise is reduced, causing environmentally inconvenient problems.

In addition, when rainwater leaks from a structure such as a soundproof tunnel, the water falls into the soundproof tunnel, causing inconvenience to the driver, and in severe cases, creating a hydroplaning on the road surface to make the road surface slippery. In winter, ice may form on the road surface, which may cause serious traffic accidents. This causes the same problem even if rainwater seeps into the inside of the soundproof wall and flows into the road.

Therefore, a soundproof wall or a soundproof tunnel must have watertightness as well as noise control performance. Existing sound insulation boards do not have reliable measures against watertightness.

For example, in the case of a transparent soundproofing board that is laminated and installed on a soundproof wall, the joint has a structure in which aluminum frames are in contact with each other and stacked, and there is no packing or caulking to secure watertightness, so noise and rainwater easily penetrate through the gap. there is

In addition, the soundproofing panel of the roof of the soundproofing tunnel provides and places a separate cover on the upper part of the joint where the aluminum frame comes into contact with each other, and arranges a packing material between the cover and the aluminum frame to block noise and rainwater despite the fact that the end is treated with caulking. Failure to do so is causing a number of problems.

This is due to the structure in which the caulking material and the packing material are simply attached by their own adhesive strength, and thus are inevitably detached and damaged when their adhesive strength is lost due to aging over time.

The roof of the soundproof tunnel is exposed to the external weather, so it is in a very poor environment due to direct sunlight, radiant heat from the sun, snow, rain, and weather conditions.

1 is a view showing a conventional sound insulation board.

Figure 1 (a) is an enlarged detailed view of the cross section of the joint of the sound insulation plate installed by being stacked in the vertical direction on the sound insulation wall. There is a gap in the horizontal direction at the joint between the sound insulation board at the top and the sound insulation board at the bottom. Since rainwater tends to flow in the direction of gravity and the direction of the gap is horizontal, only a small amount of rainwater can escape through the gap. However, since the noise is not correlated with the directionality of the gap but with the size of the gap, a large amount can easily escape. Here, the size of the gap inevitably arises due to the allowable manufacturing error of the soundproof board installed on the soundproof wall and the tolerance for installation.

1 (b) and (c) are cross-sections of different shapes, but in both cases, they are enlarged detailed views of the cross-section of the joint of the sound insulation plate installed by being stacked in the oblique direction on the roof of the sound insulation tunnel. A cover is provided at the top of the joint between the sound insulation board frame on the upper side and the sound insulation board frame on the lower side, and there is a small gap close to the vertical direction between the joint. If the gap between the joints of the sound insulation board is well sealed, rainwater will flow without problems along the path of “1”, that is, along the roof of the sound insulation tunnel. However, in general, when a long period of time elapses after the installation of the facility and the aging occurs, the packing material 240 or the caulking material 250 installed in a general way is damaged or falls off, so that the sealing performance is greatly reduced. If there is a damaged packing material 240 or caulking material 250, rainwater easily penetrates into the path of "2", that is, the gap between the sound insulation board joints. This is because the direction of the gap coincides with the rainwater that wants to flow in the direction of gravity, so that rainwater easily penetrates and escapes through the gap. In addition, in the transmission of noise, since the roof sound insulation board has nothing to do with the orientation of the gap and has a correlation with the size of the gap, a large amount can easily escape.

In addition, referring to (b) of FIG. 1, the sound insulation board of the roof part has a certain inclination at the time of design. As rainwater flows along the slope of the roof, a certain amount of rainwater may accumulate in the caulking part. In this way, the amount of rainwater collected in the portion where the caulking material 250 is installed varies depending on the slope of the roof, but a certain amount of rainwater is collected.

As described above, after the rainwater is accumulated in the caulking material 250, dust and organic matter are fixed, and thus stains are generated, resulting in a decrease in transparency of the sound insulation board and a problem in that the aesthetics are impaired.

Furthermore, there is a problem that the aging of the caulking material 250 is accelerated by the accumulated rainwater permeating through the path of "3" between the caulking material 250 and the transparent plate.

Embodiments of the present invention relate to a soundproofing board having a watertight sound leakage prevention structure installed between frames of a soundproof wall as a component of a soundproof wall or a soundproof tunnel installed around noise generating areas such as roads, railways, and factories. This sound insulation board will be referred to as a "sound insulation board" for short.

2 is a view showing a sound barrier to which a sound insulation plate 200 according to an embodiment of the present invention is applied. Fig. 2 (a) is a side view and Fig. 2 (b) is a front view.

Referring to FIG. 2, the soundproof wall foundation 2 is built on the ground 1, the soundproof wall frame 100 is fixed on the soundproof wall foundation, and the soundproof board 200 is shown stacked and installed in three stages on the soundproof wall frame.

Referring to FIG. 2, the main components of the sound barrier to which the sound insulation plate 200 according to the present embodiment is applied are the sound barrier foundation 2, a plurality of anchors 3, and a plurality of supports from the ground 1 at the bottom to the top ( 100) and a plurality of sound insulation boards 200 are installed. The sound barrier foundation is built with reinforced concrete on the ground and transfers the load of the sound barrier to the ground.

The anchor serves to connect and fix the lower end of the ice wall frame 100 and the foundation, and the soundproof wall frame is a steel H-shaped beam (H-BEAM) with high rigidity and excellent tensile strength to withstand horizontal loads caused mainly by its own weight and wind. ) is used. Each sound insulation board 200 is assembled as a finished product in a factory, and is fitted between the H-type beam and the H-type beam of the sound-proof wall frame 100, and is stacked and fixed in several stages.

3 is a view showing a soundproofing tunnel to which a soundproofing plate 200 according to an embodiment of the present invention is applied.

3, the soundproof wall foundation 2 is built on both sides on the ground 1, the soundproof wall frame 100 is fixed on the soundproof wall foundation 2, and the soundproof board 200 is stacked in several stages and installed on the soundproof wall frame this is shown

In addition, when looking at the roof of the soundproof tunnel, the upper ends of the soundproof wall frames 100 erected on both sides are connected to each other so that the soundproof tunnel roof frame 101 is installed at an angle, and the soundproof tunnel roof frame 101 has a soundproof panel 200 installed in the inclined direction. are stacked and installed.

Referring to FIG. 3, the wall portion of the soundproof tunnel has a structure similar to that of the soundproof wall, but is installed in two rows, and the roof of the soundproof tunnel has a soundproof tunnel roof frame 101 and a soundproof plate 200 installed at an angle. is different from

The soundproofing board 200 installed on the soundproofing wall is stacked in the vertical direction so that rainwater easily flows down along the surface of the soundproofing board and is not easy to penetrate into the gaps between the joints of the soundproofing board. This is because the rainwater tends to flow in the vertical direction along with gravity, but the gaps between the sound insulation board joints are formed in the horizontal direction, so the direction is different.

However, since the soundproofing board 200 installed on the roof of the soundproofing tunnel is installed at a slight inclination in the horizontal direction, it is easy for rainwater to permeate through the gaps between the joint parts of the soundproofing board. This is because the gap between the joints of the sound insulation board is formed in the vertical direction and coincides with the direction of rainwater to flow along with gravity. Therefore, watertightness against rainwater is more urgently required in the sound insulation board 200 installed on the roof of the sound insulation tunnel.

However, since noise does not have a specific directionality and is correlated with the size of the gap, the soundproofing plate 200 for the soundproof wall and the soundproofing plate 200 for the roof of the soundproofing tunnel have a difference in that the noise penetrates through the gap between the joints of the soundproofing plate and leaks. there can be no

The sound insulation board 200 is mainly installed on the sound insulation wall and stacked in the vertical direction .

5 is a soundproofing board 200 that is mainly installed obliquely on the roof of a soundproofing tunnel. In the sound insulation board of FIG. 4, as shown in FIG. 4 (c), the position of the sound insulation board 201 is located in the center of the concave groove frame 220, but in the sound insulation board of FIG. 5, as shown in FIG. ) is located close to the top of the concave groove frame 220.

This is because the soundproofing plate installed on the roof of the soundproofing tunnel minimizes the size of the right angle chin caused by the difference in thickness between the soundproofing plate 201 and the concave groove frame 220, and makes the upper surface of the soundproofing plate 200 as flat as possible to prevent rainwater This is to allow it to flow easily along the roof surface.

Here, as the material of the protruding plate frame 210, the concave groove frame 220, and the side frame 230 constituting the sound insulation board 200, aluminum or PVC-based materials of non-ferrous metal are mainly used.

6 is a partial cross-sectional view of a sound insulation board 200 according to an embodiment of the present invention in an assembled state. Fig. 6 (b) is an enlarged cross-sectional view of part "1" in Fig. 6 (a). Referring to Figure 6 (b), there is a protruding plate frame 210 at the bottom of the joint of the sound insulation board 200 and a concave groove frame 220 at the top. The positions of the protruding plate frame and the concave groove frame may be interchanged depending on the direction in which the sound insulation board is installed.

Figure 7 (b) is a cross-section of the protruding plate frame 210 perpendicular to the long axis of the protruding plate frame, there are two protruding plates 211 formed by protruding in a plate shape on the outer surface of the cross section of the protruding plate frame. Figure 7 (a) is a cross section of the concave groove frame 220 cut perpendicular to the long axis of the concave groove frame, a concave that can be filled with the projection plate of the projection plate frame and the packing material 240 attached to the projection plate. Two grooves 221 are formed opposite to the protruding plate. In order to improve the watertightness of the joint of the sound insulation board, the concave groove 221 may be provided with a caulking material 250 or other watertight material in addition to the packing material 240, and the protruding plate 211 and the concave groove 220 The cross section of can be modified in a more advanced way.

Figure 8 is a cross-sectional detailed view of the sound insulation board 200 according to an embodiment of the present invention is assembled.

8(b) to (e) are detailed cross-sections of “2” in FIG. 8(a). In FIG. 8 (b), the protruding plate 211 and the concave groove 221 are coupled to face each other, and the space between the protruding plate and the concave groove is a space where the packing material 240 or the caulking material 250 can be inserted. There is a watertight space 224.

In (c) of FIG. 8, the caulking material 250 is filled in the concave groove 221 and the protruding plate 211 is inserted into the caulking material. Rainwater or noise can penetrate only when there is a gap, but the configuration of the caulking material 250, which is provided in liquid form and integrally hardened together with the protruding plate, does not generate even a slight gap, so it is formed in a structure in which rainwater or noise cannot penetrate there is. In addition, it is formed with a sealing structure in which the caulking material 250 cannot be damaged or eliminated even when it is aged.

In (d) of FIG. 8 , the packing material 240 is attached to the protruding plate 211 and inserted into the concave groove 221 . Depending on the thickness of the packing material provided, it may be fitted with strong compression or weak compression. In order to secure excellent watertightness, it would be desirable to insert it with strong compression. The packing material 240 will be very easy to manufacture when using a material in which an adhesive is applied on one side to a rubber-based thin plate. Due to this configuration, the joints of the sound insulation board are formed in a structure in which even a minute gap is not generated and rainwater or noise cannot penetrate. In addition, it is formed with a sealing structure in which the caulking material 250 cannot be damaged or eliminated even when it is aged.

8(e) shows a structure in which a caulking material 250 and a packing material 240 are provided together in a concave groove 221. A liquid caulking material is first injected into the concave groove 221, and the packing material is attached to and inserted into the protruding plate. The liquid caulking material penetrates and evenly fills the minute gaps that may exist around the packing material due to the pressure generated when the uneven structures are inserted into each other. The effect of a structure provided with caulking material and packing material together will provide much better watertightness than a structure provided with only one material of either caulking material or packing material.

This is shaped so that the caulking material is well cured in place by providing a wider surface area so that the liquid caulking material does not flow down until it is injected and hardened.

12 shows that a top nipple 212 is formed at the end of the protruding plate 211, a compression protrusion 222 is formed inside the concave groove 220, and a locking hole 223 is formed at the inlet of the concave groove, and the packing material ( 240) and the caulking material 250 are provided together. After a certain amount of caulking material is injected into the concave groove, when the packing material attached to the protruding plate is inserted, the caulking material will fill the gap by digging into the surrounding gap by the inserted pressure. In addition, the curved nipple compresses the packing material around the curved nipple with a higher pressure, and prevents the packing material from being torn when the packing material is compressed. The compression protrusion locally compresses the packing material inserted into the concave groove, and the engaging hole locally compresses the packing material on both sides of the inlet of the concave groove. In addition, the curved faucet, the hook, and the packing material complement each other in an interlocking structure at the entrance of the concave groove so that they do not separate from each other and maintain their position. As a result, the joint of the sound insulation board secures excellent watertightness and secures a sealing structure in which the watertight material does not fall off, enabling it to maintain its function semi-permanently.

13 to 15 are local cross-sectional detailed views illustrating effects of the sound insulation board 200 according to various embodiments of the present invention. 13-15 (a) shows a distribution of compressive force generated when the packing material 240 attached to the protruding plate 211 is inserted into the concave groove 220, respectively. It is obvious that the effect of watertightness varies depending on the magnitude of the compressive force distributed around the packing material. 13-15 (b) shows paths through which noise or rainwater is transmitted, and each path is a path in which noise or rainwater travels along the surface of the protruding plate 211 and the packing material 240 for a long time, and noise or rainwater is easily passed through. It shows impenetrability.
