Description

A tunnel type soundproofing walls for a ceiling of a soundproof tunnel

The present invention relates to a soundproof tunnel, and more particularly, to a ceiling leakage prevention structure of a soundproof tunnel capable of preventing leakage of water from a ceiling of a soundproof tunnel.

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

At this time, there is a problem that the blocking wall or the sound-absorbing wall is not safe from the noise inside the road from a certain floor height or more 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 the structural stability of the soundproof wall structure and the foundation ground due to wind load.

Therefore, in recent years, in order to overcome the height limit of the soundproof wall, the application of the soundproof tunnel is increasing rapidly. The soundproof tunnels completely close both sides and top of the road so that noise inside the road can not escape to the outside, and effectively absorbs the noise inside the road, thereby also reducing driving noise affecting the driver.

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

Referring to FIG. 1, a conventional soundproof tunnel includes a concrete foundation 100 cured on both sides of a road at a predetermined height, a side wall support 200 installed at a predetermined interval on the concrete foundation 100, A ceiling support 300 installed between the support 200 and the side wall support to form a ceiling part and soundproof panels 400 and 400 'assembled between the side wall supports 200 and the ceiling support 300. Here, the soundproof panel 400 'assembled in the ceiling strut 300 is widely used as a transparent panel made of a transparent plastic material or a laminated glass, or a panel in which such a transparent panel is sandwiched by an aluminum frame.

Korean Utility Model Registration No. 446296 of the Republic of Korea, therefore, discloses a structure in which a square pipe type support is installed at even intervals in the transverse and longitudinal directions along the tunnel length direction; A guide member made of a divided body and fixed to the front surface of the support by a fastening piece and having an elastic body coupled to both the left and right sides of the exposed surface; And a fixing plate for pressing and fixing the corresponding ends of the soundproof plate, the middle portions of which are coupled to the guide member by fastening bolts and nuts, and both bent ends thereof are in close contact with the elastic body. Such a soundproof panel of Korean Utility Model No. 446296 uses a rectangular panel that is not sandwiched by the frame.

However, the above-mentioned Korean Utility Model No. 446296 discloses that a fixing bolt is provided in a bolt head engaging groove of a guide member fixed to each support for securing the sound insulation plate to the ceiling support, and then the fixing plate is coupled to the guide member, The assembling work is troublesome and the workability is deteriorated. In addition, since a large number of components are required to assemble the sound insulation board, the construction cost is high. Particularly, the above-mentioned Korean Utility Model No. 446296 discloses a structure in which a guide groove for installing an elastic body made of a rubber material is formed in the longitudinal direction, so that the elastic body is inserted into the guide groove before the sound- There is a problem that the rubber pad is attached to the inside of the bent end of the fixing plate so that the soundproof plate can be resiliently fixed. However, when the rubber pad and the soundproof plate are not completely adhered to each other, leakage of rainwater occurs.

On the other hand, Korean Patent Registration No. 1001032 discloses a structure in which a post spaced at both sides of a road at regular intervals and forming a body of a soundproof tunnel, a soundproof plate provided between the posts to absorb noise of the vehicle, A transparent soundproof plate provided on both sides of the roof frame to form a roof of the soundproof tunnel, and a pressing part installed on the roof frame to press-fix the pressing part of the transparent sound insulation panel A 'maintenance-easy soundproof tunnel' comprising a fixed cover has been proposed. Alternatively, in the above-mentioned Korean Patent No. 1001032, an insertion hole is formed in the pressing portion constituting the transparent sound insulation plate, and a lower portion of the pressing portion constituting the corresponding fixed cover is fitted and fixed in the insertion groove of the transparent sound insulation plate A structure in which an insertion protrusion for preventing the flow of the transparent sound insulation plate is formed has been proposed.

However, the above-mentioned Korean Patent No. 1001032 discloses that the structure of the transparent sound insulation panel is formed by inserting the transparent panel into a rectangular frame such as an aluminum frame, such as an upper frame, a lower frame, a left frame and a right frame, There is a problem in that the manufacturing cost of the transparent sound insulation plate itself is increased as compared with the use of the transparent sound insulation panel itself. Thus, the transparent sound insulation panel in which the transparent panel is sandwiched between the frame and the roof frame has a problem in that rainwater can not be drained smoothly when installed on a roof frame. In other words, the above-described transparent soundproof panel is assembled in a horizontal structure on the roof frame in a state in which the frame has a considerable thickness on the outer circumference of the transparent panel, so that when rain falls on the transparent panel, the rain- . In addition, Korean Patent Registration No. 1001032 discloses that rainwater is prevented from flowing into the inside of a soundproof tunnel through a filler for space plugging between the side of the transparent soundproof panel and the roof frame. However, Since the filling material is installed in a state that the transparent sound insulating plate is fixed to the roof frame by the fixing cover, as the installation position is located inside the roof frame, it is difficult to carry out the filling work for the space filling.

Korean Patent Laid-Open Publication No. 2010-133342 discloses a transparent plate assembly having H beams arranged at regular intervals on a concrete foundation and having a rectangular transparent plate and a frame coupled to the upper / lower / left / right edges of the transparent plate. The bracket being welded and fixed to the center of the surface of the H beam and having a locking hole in the shape of a keyhole at an upper end thereof; A frame of a transparent plate assembly located on both left and right sides of the bracket and provided with a backflow preventing jaw; A fixed frame having a pressing portion for pressing an upper surface of the frame; A fastening bolt and a loosening preventing nut for pressing and fixing the fastening frame to the upper surface of the frame; A cover positioned to cover the frame and the fixed frame; A fixing bolt penetrating through the cover and the fixing frame and fastened to the frame; And a waterproof packing coupled to the fixing bolt and closely attached to the cover. Korean Unexamined Patent Publication No. 2010-133342 is a fixing device for preventing water leakage to the inside of a tunnel during rainstorm and preventing shaking of a transparent panel due to running of a vehicle.

However, Korean Patent Laid-Open Publication No. 2010-133342 mentioned above is further provided with a backflow preventing jig protruding from the upper surface of the frame to prevent backflow of rainwater, and in order to fix such a frame, And the fixing frame is fixed by the fixing bolt in a state that the frame and the fixing frame are covered with the cover. Therefore, the assembling work is troublesome and the workability is deteriorated, and the fixing device is composed of a plurality of components There is a problem that the construction cost is increased.

In Korean Patent No. 869337, a 'coupling device for a steel frame for a soundproof tunnel and a soundproofing plate' using a connecting body for fixing the soundproofing plate has been proposed. Korean Patent No. 869337 discloses a structure in which a soundproof plate is provided between a body portion and a lid portion constituting a connecting body, and two buffer bars made of a rubber buffer material are provided on the body portion and the lid portion, And is configured to perform a buffering action before being transmitted to the strut.

However, the above Korean Patent No. 869337 has a problem in that it is necessary to install the buffering bar on the body part and the cover part before fitting the sound absorbing plate into the steel support, and when the buffer bar made of the rubber material is used for a long time The buffering force and the hermetic sealing force are gradually lost, so that the leakage of rainwater can not be blocked.

As a result, the existing soundproof tunnels have a problem in that, when the soundproof packing or the buffer bar of the rubber material installed on the ceiling is blocked for a long time,

There is a problem in that leakage of water into the inside of the sound-absorbing tunnel occurs due to a time point at which the function is lost as the physical properties are changed due to exposure to sunlight (ultraviolet rays)

In addition, there is a problem in that leaky phenomenon occurs due to a shape change or breakage phenomenon in a soundproof packing or a buffer bar as the soundproof plate flows in the strut due to natural wind pressure or wind pressure generated in a vehicle passing through a soundproof tunnel.

Accordingly, the present invention has been made to solve the general problems of the conventional sound insulation tunnel,
