Problems solved by technology

[0002] At the entrance of the underground parking lot, since the parking lot is closed when the vehicle enters the ground, the sound generated further forms an echo, thereby generating a larger noise. Therefore, at the entrance of the slope of the underground parking lot, the cement slope is often equipped with The serrated protrusions can play a role in reducing noise; in addition, for the damaged section of the road surface, a layer of rubber sheet with smooth surface will be laid to reduce the noise when the car passes by, but the surface of the rubber sheet is smooth, which is prone to accidents
Neither of the above two measures can significantly reduce noise, and there are deficiencies

Embodiment Construction

[0013] Such as figure 1 As shown, the present invention relates to a noise reduction board, the noise reduction board 1 is made of rubber, the surface of the noise reduction board 1 is provided with evenly distributed protrusions 2, and the protrusions 3 are circular; The surface of the noise reduction plate 1 is also provided with evenly distributed installation through holes 3 . The number of the protrusions 3 is 48, and the number of the installation through holes 3 is 4.

[0014] Such as figure 2 As mentioned above, the protrusions 3 are elongated, and the number is 16, which are evenly distributed on the surface of the noise reduction plate 1 . The number of the installation through holes 3 is four, which are evenly distributed on the surface of the noise reduction plate 1 .

[0015] The surface of the noise reduction board 1 is coated with paint, so that the noise reduction board 1 presents different colors, such as red, yellow, green or blue.

Abstract

The invention provides a noise-reducing plate which is made of rubber. A plurality of uniformly distributed bulges are formed on the surface of the noise-reducing plate, and are circular or strip-shaped; uniformly distributed through holes are formed in the surface of the noise-reducing plate. The noise-reducing plate has the beneficial effects that the noise-reducing plate is laid on an underground parking or pavement damaged section, so that city noise can be lowered and the environment is beautified; in addition, the noise-reducing plates with different colors are laid on the pavement damaged section, so that a certain caution function can be achieved.

Description

technical field [0001] The invention belongs to the field of noise reduction equipment, in particular to a noise reduction board. Background technique [0002] At the entrance of the underground parking lot, since the parking lot is closed when the vehicle enters the ground, the sound generated further forms an echo, thereby generating a larger noise. Therefore, at the entrance of the slope of the underground parking lot, the cement slope is often equipped with The serrated protrusions can reduce noise to a certain extent; in addition, for the damaged section of the road surface, a layer of rubber sheet with smooth surface will be laid to reduce the noise when the car passes by, but the surface of the rubber sheet is smooth, which is prone to accidents . Neither of the above two measures can significantly reduce the noise, so there are deficiencies. Contents of the invention [0003] The problem to be solved by the present invention is to provide a noise reduction board....
