Description

Technical Field

[0001] The utility model belongs to the technical field of road and bridge sound insulation facilities, and more specifically, particularly relates to a sound insulation screen for roads and bridges. Background Art

[0002] At positions where roads and bridges are close to residential areas, sound insulation screens are generally installed on both sides of the roads and bridges. Existing sound insulation screens are generally installed on both sides of the road through drilled bolts. Generally, existing sound insulation screens mostly adopt a steel plate structure containing sound-absorbing cotton inside. At the same time, in order to avoid blocking the driver's line of sight, a perspective window structure made of acrylic board is generally arranged in the middle of the sound insulation screen.

[0003] The existing application number is: CN201710297774.9. This invention discloses a sound insulation screen, which includes a cover body evenly distributed with sound inlet openings and a sound absorption board arranged inside the cover body. The sound absorption board is a plate-like structure composed of a porous metal film. After the noise enters the cover body from the evenly distributed sound inlet openings on the cover body, the noise is weakened. Then, under the action of the plate-like structure composed of the porous metal film arranged inside it, the noise is deeply reduced through the small holes on the porous metal film, thereby achieving an ideal noise reduction effect. The sound absorption board composed of the porous metal film is very light in weight and will not cause an installation burden.

[0004] Based on the above, existing sound insulation screens are generally of an integral structure. When there is strong wind weather, the strong wind directly blows on the sound insulation screen, which easily causes the sound insulation screen to receive a large impact, resulting in the loosening of the installation bolts of the sound insulation screen and affecting the installation stability of the sound insulation screen.
