Description

H-beam connection part leak blocking type soundproof tunnel}

The present invention relates to a soundproof tunnel, and in particular, an H-beam connection that minimizes interference caused by a reinforcing plate and a fastening bolt at the H-beam connection part to block the lower cut of the support pipe supported on the upper side of the H-beam and the possibility of leakage due to this It relates to a leak-blocking type soundproof tunnel in the area.

Due to recent urban development and the expansion of wide area networks of roads and railroads, a number of roads are being formed in areas adjacent to residential areas.

Accordingly, in order to block or absorb noise generated on the roadside, various types of barrier walls or sound-absorbing walls are installed on the roadside to prevent the noise from spreading to the outside, but the barrier walls or sound-absorbing walls are at the installation height. There are limitations, it is difficult to secure structural stability when a wind load occurs, and the part of the building structure located above a certain height is not safe from noise inside the road.

In order to overcome the limitations of such barrier walls or sound-absorbing walls, the application cases of soundproof tunnels having a tunnel-type structure are increasing. The soundproof tunnel has the advantage of being able to seal both sides and the upper part of the road to prevent the noise inside the road from leaking out, and at the same time to absorb the noise inside the road to reduce the driving noise that affects the driver.

In the soundproof tunnel according to the prior art, as shown in FIGS. 1A and 1B , the wall part 1A and the roof part 1B are formed in a tunnel shape, and the lateral support pipe 20a and the longitudinal support pipe 20b are the center In the lower side, the transverse H-beam (10a) and the longitudinal H-beam (10b) are supported, and on the upper side, a plurality of transparent plates 30 are arranged in a checkerboard shape in rows in the transverse and longitudinal directions. In addition, the spaced gap between the transparent plates 30 is covered by the upper cover 40 to prevent leakage of water through the spaced gap between the transparent plates 30 .

However, in the case of such a conventional soundproof tunnel, there is no problem in the installation of the transverse support pipe 20a as shown in FIG. 1c in the general section of the transverse H-beam 10a. The lower portion of the transverse support pipe 20a had to be cut due to interference between the upper reinforcing plate 51a and the upper fastening bolt 52 used to connect the upper flange 12a of the transverse H-beam 10a. As a result, the transverse H-beam (10a) and the transverse support pipe (20a) did not adhere to each other and a spaced weak part occurred, resulting in a problem of water leakage through the corresponding part. If such a leak problem is left as it is, corrosion occurs in the transverse H-beam 10a and the longitudinal H-beam 10b connected thereto, and not only structurally weakens the soundproof tunnel as a whole, but also greatly damages the aesthetics due to rust a problem has arisen. In addition, due to water leakage, the road surface was frozen and the water film phenomenon occurred, which caused traffic accidents. In particular, since a small amount of water leakage can have an adverse effect in that the leakage site is a connection portion of the transverse H-beam 10a, this problem must be improved.

To this end, a pair of first protrusion lines 131 spaced apart from each other are formed on the upper surface of the transverse support pipe 130a along the longitudinal direction, and the upper cover 150 extends downward from the upper body 151 . A pair of extension portions 152 are provided, and a first snap groove 152a snap-coupled to the first protrusion line 131 is formed outside the lower end of the extension portion 152 . Accordingly, it is possible to simply snap the upper cover 150 to the lateral support pipe 130a without using a separate fastening part.

However, if it is necessary to fix the upper cover 150 more firmly, it may be additionally fixed using a bolt 156 . Even so, this snapping coupling structure has the advantage of making construction more convenient because it can be temporarily fixed before completely fixing the upper cover 150 to the transverse support pipe 130a using the bolt 156. have.

On the other hand, in the central portion of the upper cover 150, a head groove 151a into which the head of the bolt 156 for fixing the upper cover 150 to the lateral support pipe 130a is introduced is formed, and the upper cover 150 is formed. An upper cap 155 of an inverted U-shaped cross-section that covers the head groove 151a of the upper side is installed.

Further, a second protrusion line 151b is formed on both side walls of the head groove 151a of the upper cover 150, and the second protrusion line 151b and the second protrusion line 151b are snappingly coupled to the lower end of the upper cap 155. A second snap groove 155a is formed. Accordingly, the upper cap 155 can be simply snapped to the upper cover 150 . In addition, when the second protrusion line 151b and the second snap groove 155a are snapped together, the second protrusion line 151b and the second snap groove 155a come into closer contact with each other and the head groove An additional effect of blocking the water that penetrates and flows along the wall surface of (151a) can be expected.

Furthermore, as can be seen in the enlarged part of FIG. 11 , a packing 156 for preventing moisture penetration is further installed on the lower inclined surface of the second protrusion line 151b along the longitudinal direction of the second protrusion line 151b, so that the second protrusion line The gap between the 151b and the second snap groove 155a is thoroughly blocked so that even a small amount of moisture does not penetrate. Here, in the case of the lower inclined surface of the second protrusion line 151b, unlike the upper inclined surface, the second snap groove 155a is not a part where slipping should occur during snapping engagement with the second snap groove 155a. ), since it is a part in contact with the inner surface, it is suitable for installing the packing 156 for preventing moisture penetration.

As such, in the fifth modified implementation of the present invention, not only the snapping coupling function of the second protrusion line 151b and the second snap groove 155a, but also a small amount of moisture penetrating along the wall surface of the head groove 151a can be thoroughly blocked. One can note the moisturizing effect. If moisture penetrates through the head groove 151a, the moisture penetrates to a deeper point downward through the bolt hole 151c formed therein and stagnates, leading to a problem in which corrosion is expanded.

In addition, fitting grooves 151b are formed on the lower surfaces of both ends of the upper cover 150 , and the first packing 153 for water retention is installed between the transparent plate 140 and the transparent plate 140 . A second packing 154 for blocking the gap is installed between the direction support pipe 130a to block the penetration of moisture.

As described above, the configuration related to the upper cover 150 has been mainly described with respect to the transverse support pipe 130a for convenience of description, but it is also applied to the longitudinal support pipe 130b as it is. That is, after forming a pair of first protrusion lines on the upper surface of the longitudinal support pipe 130b along the longitudinal direction, only the direction of the upper cover 150 is changed from the transverse direction to the longitudinal direction, and the snapping coupling is performed as it is. .

Meanwhile, in the case of the remaining components not described in the fifth modified embodiment, since they are substantially the same as in the previous modified embodiment, a further detailed description will be omitted.

Although preferred embodiments of the present invention have been described above, various changes, modifications and equivalents may be used in the present invention. It is clear that the present invention can be equally applied by appropriately modifying the above embodiments. Accordingly, the above description is not intended to limit the scope of the present invention, which is defined by the limits of the following claims.
