Description

Earthquake-resistant structural noise attenuating roof soundproof panel fixing device {ROOF STRUCTURE FOR SOUNDPROOF TUNNEL}

The present invention relates to a ceiling structure of a tunnel-type soundproof wall that reduces driving noise of a vehicle generated on a road or bridge, and more particularly, in response to an external force in the event of an earthquake, vibration, or strong wind, the soundproof plate rolls vertically and It relates to an earthquake-resistant structure-type noise attenuation function roof soundproofing plate fixing device that slides in a horizontal direction to prevent deformation and damage, and to improve noise dispersion and attenuation effects.

Today, for the purpose of reducing traffic noise around roads or bridges, various soundproofing facilities such as soundproofing dikes, soundproofing walls, soundproofing tunnels, etc., which block or hinder the transmission path of noise, are installed around roads, railroads, or around factories.

Among them, the soundproof tunnel was developed as one of the alternatives due to the limitation of the height of the soundproof wall or soundproof weir due to high-rise apartment buildings and urban density. Since the path is directly blocked, the range of noise blocking up to high floors is increased, and it is preferred as a representative technology that increases the noise reduction effect for high-rise residential areas near roads and downtown traffic facilities where high-rise buildings are concentrated.

These soundproof tunnels are classified into curved, flat, and mixed types according to the formation of walls and ceilings. The curved type is a type with high external force resistance due to the arching effect by designing the entire post in a semicircular or parabolic shape. , and the hybrid type uses straight lines and curves at the same time by installing vertical supports on the wall and designing curves between the ends of the supports.

In general, flat soundproof tunnels have structurally weak limitations because they cannot sufficiently absorb and dissipate bending moment acting in the direction of travel and perpendicular to the direction of the road due to vibration or wind load caused by vehicle traffic.

That is, the flat soundproof tunnel has a problem in that the ceiling structure is easily deformed or damaged because it is transmitted to the soundproof plate as it is when an earthquake, vibration, or strong wind occurs.

A noise reduction unit 22 is formed on both sides of the support frame 20 to attenuate and disperse noise through micro-vibration and reflection and refraction, and cause a change in the cross-sectional area and path of the passage through which the sound passes;
A diffraction inducing protrusion 22a is protruded from the noise inlet end of the noise reduction unit 22 to induce diffraction of the noise introduced into the inside;
An earthquake-resistant structure-type noise reduction function roof soundproofing plate fixing device, characterized in that sealed with a sealant (80) so that water does not leak into the gap between the soundproofing plates (10) and both edges of the cover (30).
delete The lower edge portion of the sound insulation boards 10 placed side by side at regular intervals is supported and supported, lower fitting grooves 21 are formed on both edges of the upper surface, and sliders 23 are integrally formed on both sides of the lower surface Support frame 20; The sound insulation boards 10 are formed to adhere to the support frame 20 by elastically pressing the upper edge portion by elastic deformation, and the counter beam 31 is formed in the center of the upper surface, and the upper fitting groove 32 is formed on both edges of the lower surface This formed cover 30; Between the support frame 20 and the cover 30 and the sound insulation board 10 by inserting each into the lower fitting groove 21 of the support frame 20 and the upper fitting groove 32 of the cover 30 An elastic rod 40 formed in a circular cross section to close the gap and induce natural rolling of the sound insulation boards 10; In order to hold the cover 30 in a state in which the upper surface edge portions of the sound insulation boards 10 are pressed, a direct screw ( 50); A stretchable waterproof tape 60 attached to seal the gap and to impart adhesiveness and waterproofness to the upper edge portions of the sound insulation boards 10 and the upper central portion of the support frame 20; A closing cap 70 formed to cover the direct connection screw 50 so as not to be exposed to the outside, and elastically fitted into and coupled to the counter beam 31 of the cover 30 by elastic deformation; It is fixed on the girder 1 arranged at regular intervals in the traveling direction of the road, and guide grooves 91 are formed on the upper surface to guide the slider 23 of the support frame 20 to slide. Fixed frame 90 );
Noise reduction units 92 are formed on both sides of the fixing frame 90 to attenuate and disperse noise through micro-vibration, reflection and refraction, and change the cross-sectional area and path of the passage through which the sound passes;
A diffraction inducing protrusion 22a is protruded from the noise inlet end of the noise reduction unit 92 to induce diffraction of the noise introduced into the inside;
