Description

Soundproof tunnel with soundproof plate drop-off prevention structure

The present invention relates to a soundproof tunnel provided for soundproofing, and more particularly, installation and separation of soundproofing plates without loss of cross-section of the post even when upper construction is impossible, such as installation of a stiffener provided to prevent buckling of the post. It is easily possible and further relates to a soundproof tunnel having a structure that effectively prevents the soundproofing plate from falling off.

As is well known, the increase in traffic noise passing through adjacent sections of high-rise apartments is rapidly increasing due to the recent development of new towns and the expansion of the wide area network of roads and railroads. Accordingly, in order to block or absorb noise, various blocking walls or sound-absorbing walls are installed on the roadside to prevent the noise inside the road from directly affecting the building.

At this time, there is a problem that the barrier wall or the sound-absorbing wall is not safe from noise inside the road from a certain floor height or higher due to the limitation of the installation height. This is because there is a limit to increasing the height of the sound barrier indefinitely in order to secure the structural stability of the sound barrier structure and the foundation ground due to the wind load.

Therefore, in recent years, in order to overcome the height limit of the soundproof wall, the application cases of soundproof tunnels are rapidly increasing. The soundproof tunnel completely seals both sides and upper part of the road to prevent the noise inside the road from leaking out, and at the same time, it effectively absorbs the noise inside the road and reduces the driving noise that affects the driver. As a conventional technology related to such a soundproof tunnel, there is registered Patent No. 10-1921238 (November 16, 2018) and the like.

In order to solve this, as shown in FIG. 1b, construction is often performed in the form of inserting the soundproofing plate 3 into the removed portion by removing the flesh (flange) of the front or rear side of the holding, but the cross-sectional loss of such a holding is made. acts as a fatal defect in the structural stability of the soundproof tunnel, and causes rust and fatal defects due to corrosion of the cut surface. In addition, if the sound insulation board 3 is damaged, there is a limitation that partial replacement of the sound insulation board 3 is impossible unless the stiffener S is removed even in the process of dismantling and reinstalling it.

The present invention is to solve the above problems, and by allowing the soundproofing plate to be installed in the front or the rear side, even when upper construction is impossible, such as installation of a stiffener provided to prevent buckling of the prop, without loss of the cross section of the soundproofing plate It aims to enable easy installation and disassembly.

Hereinafter, with reference to the accompanying drawings, a soundproof tunnel (hereinafter, this soundproof tunnel) having a soundproofing plate drop-off preventing structure according to the present invention will be described in detail.

This soundproof tunnel has a structure that enables easy installation and separation of soundproofing boards without loss of cross-section of theposts even when upper construction is impossible, such as installation of a stiffener provided to prevent buckling of the props, and further effectively prevents the soundproofing boards from falling off It relates to a soundproof tunnel having a, as shown in FIGS. 1 to 11, characterized in that the detachment of the soundproofing plate is made from the front or rear side, and the first and second posts (1) (2) that are spaced apart from each other; It includes a coupling means for coupling the soundproofing plate (3), the soundproofing plate (3) to the support installed between the two posts.

In this soundproof tunnel, since the soundproofing board 3 is detached from the front or rear side, it is possible to install and separate the soundproofing board 3 without loss of the cross-section of the post as shown in FIG. 1 , and as described above. The front or rear detachment of the sound insulation board 3 can be realized by the above-described coupling means.

Specifically, the post is configured to provide the foundation of the soundproof tunnel, and is composed of an H-beam composed of a web (W) and a pair of flanges (F). Since these posts are not much different from the general H-beam, a detailed description will be omitted. However, the difference from the general H-beam is that the upper part is curved to form the ceiling to compose the soundproof tunnel, and this also corresponds to the general matter of the soundproof tunnel using the H-beam post.

In the description of the present invention, among a pair of posts spaced apart from each other for convenience of explanation, one post is named as the first post (1) and the other post is named as the second post (2). . Here, the first and second are relative concepts rather than absolute concepts, and it is revealed that they are not specified by any particular prop.

Next, the soundproofing plate 3 is a configuration coupled to the posts to give a soundproofing effect to the soundproof tunnel, and is coupled between the first and second posts 1 and 2 spaced apart from each other, particularly as shown in FIG. As shown, this soundproof tunnel is characterized in that for front and rear installation, the soundproofing plate 3 has a shorter length than the distance between the webs W of the first and second posts 1 and 2 .

Accordingly, this soundproof tunnel can be constructed in a form in which the soundproofing board 3 is inserted obliquely from the front (or rear) of the post, as shown in FIGS. 2 to 4, so that even if the upper construction is impossible, the soundproofing board 3 without damaging the post ) can be installed.

Under the above-described front and rear installation features, when the soundproof plate 3 is pushed toward the first post 1 side by an external force as shown in the figure at the bottom of FIG. 2 , there is a gap between the soundproof plate 3 and the second post 2 . However, this eventually results in the separation of the soundproofing plate 3, as a means for fixing the soundproofing plate 3 to the post, it is necessary to replace the a-angle for fixing the plate or to further provide an additional coupling means. .

The present invention intends to present a coupling means that can replace the above-described angle and effectively prevent the soundproof plate 3 from falling off. This coupling means realizes prevention of drop-off of the soundproof plate 3 by coupling one end of the soundproof plate 3 to the first post 1 and the other end to the second post 2 .

Hereinafter, by introducing various embodiments of the present invention related to the coupling means, features and effects according to each embodiment will be described together. For convenience of description, the coupling means according to each embodiment is assigned a number of each embodiment, for example, another coupling means in the first embodiment will be named as the first coupling means 5A.

In the above, the coupling between the vertical support 54 and the vertical frame v30 can be utilized in various ways such as welding, bolting, and bonding, and in particular, the binding portion 541 of the vertical support 54 is directly connected independently of the above coupling. It is preferable to be coupled to the vertical frame (v30) through the screw (52). Unlike the above-described horizontal support 53, the vertical support 54 has a possibility that it can be separated from the frame 30 by an external force in the lateral direction, so the coupling between the vertical support 54 and the vertical frame v30 is more robust. because it needs to be done.
