Description

Soundproof tunnel with seismic structure}

The present invention relates to a soundproof tunnel, and more particularly, to a soundproof tunnel having an earthquake-resistant structure capable of preventing deformation of a structure and damage to a soundproof panel caused by an earthquake.

In general, since a sound barrier is a kind of distance attenuation concept and is a method of reducing noise by a path difference generated while sound is diffracted, a very high sound barrier is required in the case of a high-rise building. If the sound receiving point is located higher than the noise source, the reduction effect by the soundproof wall has a serious limitation, and in the case of the upper floors, there is a problem of being exposed to the direct sound generated from the noise source.

The soundproof tunnel to solve this problem is freed from noise pollution by completely blocking direct sound generated from noise sources, and it is possible to secure a satisfactory soundproofing effect by blocking sound diffraction even in low-rise areas, and it is possible to reduce the factor of landscape obstruction by reducing the height. It has the advantage of being minimized and securing structural safety. As such, the soundproof tunnel is a representative method for perfect noise prevention by minimizing the effect of diffracted sound generated throughout the upper and lower floors in the existing vertical straight soundproof wall.

Conventional soundproof tunnels have a problem in that a lot of construction costs are required because the design is made in consideration of the safety factor to prevent the collapse of the whole or a specific part in the event of an earthquake. In particular, since the post has a structure in which it is welded to the base frame, it is difficult to solve the moment problem.

When the cover member 103 is moved toward the panel member 101 due to the displacement of the post 20 or the roof frame 30, the displacement amount absorbing member 110 installed between the cover member 103 and the frame member 102 While being plastically deformed, the moving amount of the cover member 103 is absorbed. This can prevent an external force acting on the cover member 103 from being directly transmitted to the panel member 101 and being damaged.

As described above, the soundproof tunnel having an earthquake-resistant structure according to the present invention can minimize the displacement of the post or the amount of displacement of the roof frame due to earthquake, load of the structure, etc., and can prevent damage to the soundproof panel supported by them. there is.
