Description

A tunnel type soundproofing walls}

The present invention relates to a tunnel soundproof wall, and more particularly, by supporting the transparent soundproof panel over the first and second stages, it is possible to secure safety with the effect of distributing snow load, and improve the coupling structure of the roof support and the transparent soundproof panel. The present invention relates to a tunnel soundproof wall which can improve workability.

As is well known, due to the development of new towns and the wider network of roads and railways, the traffic noise passing through adjacent sections of high-rise apartments is increasing rapidly. Accordingly, in order to block or absorb the noise, various barrier 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, the blocking wall or sound-absorbing wall is a problem that is not safe from the noise inside the road from a certain floor or higher due to the limitation of the installation height. This is because there is a limit to increase the height of the soundproof wall indefinitely in order to secure structural stability of the soundproof wall structure and the foundation ground due to the wind load.

Therefore, in recent years, in order to overcome the height limitation of the sound barrier, the application cases of the tunnel sound barrier are rapidly increasing. The tunnel soundproof wall completely seals both sides and the upper part of the road to prevent the noise inside the road from leaking to the outside, and at the same time, it effectively absorbs the noise inside the road and reduces the running noise affecting the driver.

1 is a plan view showing a typical example of a conventional tunnel sound barrier.

Referring to Figure 1, the conventional tunnel soundproof walls are placed on both sides of the road to a certain height of the concrete foundation 100, side wall support 200, which is erected at equal intervals on top of the concrete foundation 100, the opposite side walls Roof pillars 300 installed between the pillars 200 and the side wall pillars, the side wall soundproofing panel 400 installed in the stacked manner on the side wall pillars 200, and the roof assembled between the roof pillars 300. Soundproof panel 400 '. Here, the roof soundproofing panel 400 'assembled to the roof support 300 is a transparent panel made of transparent synthetic resin material (polycarbonate resin or acrylic resin) or laminated glass, or such a transparent panel sandwiched with a square frame made of aluminum. I use it.

Thus, Korean Patent Publication No. 2010-133342 discloses a transparent plate assembly having an H beam installed at a predetermined interval on a concrete foundation and having a rectangular transparent plate and a frame coupled to upper, lower, left, and right edges of the transparent plate. A tunnel-type soundproof wall fixing device for fixing a beam to the H beam, comprising: a bracket fixed at the center of the surface of the H beam and having a keyhole shape engaging hole formed at an upper end thereof; Frames of the transparent plate assembly which is located on the left and right sides of the bracket and the backflow prevention jaw is installed; A fixed frame having a pressing unit for pressing the upper surface of the frame; A fastening bolt and an anti-loosening nut for pressing and fixing the fixing frame to an upper surface of the frame; A cover positioned to cover the frame and the fixed frame; A fixing bolt fastened to the frame by passing through the cover and the fixing frame; Tunneled sound barrier fixing device has been proposed, including; and a waterproof packing coupled to the fixing bolt to be in close contact with the cover. The Republic of Korea Patent Publication No. 2010-133342 as described above is a fixing device for preventing the leakage to the inside of the tunnel during rain and to prevent the tremor of the transparent panel due to the vehicle running.

However, the Republic of Korea Patent Publication No. 2010-133342 is protruding from the upper surface portion of the frame is provided with a non-return bump to prevent the backflow of rainwater is further installed in the frame, fastening bolts for fixing the frame to fix the frame After fixing to the bracket by the bracket, the structure is fixed by the fixing bolt while the frame and the fixing frame is covered with a cover, the assembly work is cumbersome, the workability is reduced, and the fixing device is composed of a plurality of components There is a problem that takes a lot of construction costs.

On the other hand, the Republic of Korea Patent No. 1001032 is spaced apart at regular intervals on both sides of the road and the post forming the body of the soundproof tunnel, the soundproof plate is installed between the post to absorb the noise of the vehicle, and between the upper end of the post Installed in the roof frame to form a roof of the soundproof tunnel, and a transparent soundproof plate is installed between the roof frame and the seating portion is formed on both sides, and the pressing portion is installed on the roof frame to press the fixing portion of the transparent soundproof plate A soundproof tunnel for easy maintenance, which includes a fixing cover, has been proposed. In another embodiment, the Republic of Korea Patent No. 1001032 is formed in the mounting portion formed in the transparent soundproof plate, and corresponding to the lower portion of the fixing cover pressing portion is fitted into the insertion groove of the transparent soundproof plate corresponding to the transparent soundproof plate A structure in which an insertion protrusion is formed to prevent flow has been proposed.

However, the Republic of Korea Patent No. 1001032 is a lot of the upper part of the transparent sound insulation board according to fixing the seating part by fixing cover bolted to the roof frame in the state seated on the both ends of the roof frame structure of the structure extending from the transparent soundproof plate When the snow is accumulated, there is a problem in that the mounting portion is broken because a large load is applied to the mounting portion. In other words, the Republic of Korea Patent No. 1001032 is that the transparent soundproof plate is fixed to the roof frame depending on the seating portion, when the high snow load is caught on the transparent soundproof plate, the mounting portion is broken and the transparent soundproof plate can be separated and dropped from the roof frame There is a safety problem.

In addition, the Republic of Korea Patent No. 1001032 has an insertion groove formed in the seating portion of the transparent soundproof plate, by placing an insertion protrusion in the pressing portion of the fixing cover corresponding to the transparent soundproof plate is a roof frame by fixing the insertion protrusion in the insertion groove Although it is proposed that the structure does not flow on the roof column, the operation of inserting the insertion protrusion into the insertion groove is such that the transparent soundproof plate and the fixing cover are placed at the correct position, that is, the position where the insertion protrusion can be inserted into the insertion groove. As the work is performed only in the state, the work is quite cumbersome. When the transparent soundproof plate and the fixed cover are combined with the insertion protrusion not inserted into the insertion groove due to the carelessness of the worker during the work, the pressing force of the fixed cover is applied to the pressurized portion of the transparent soundproof plate. As a result, it may not be delivered, and as a result, the transparent sound insulation board may come off the roof frame. The.

In particular, when the actual tunnel soundproof wall is constructed, the sidewall posts installed on the concrete foundation cannot be built at an exact angle of 90 degrees on the concrete foundation, and the spacing between each sidewall posts cannot also be installed at exactly equal intervals. The roof posts to be connected are also constructed with slightly different distances as well as different angles. Accordingly, as shown in the Republic of Korea Patent No. 1001032, the insertion groove is formed in the seating portion of the transparent soundproof plate, and the pressing portion of the corresponding fixing cover is inserted into the insertion projection in the insertion groove by fixing the insertion projection in the insertion groove to the transparent soundproof plate In the case of applying a structure that does not flow on the roof frame (roof column), since the angle and spacing of the roof column are different, a considerable difficulty is involved in aligning the coupling position between the insertion protrusion and the insertion groove.
