Stair noise absorption structure
The invention provides a stair noise absorption structure which comprises a stair body, a bottom plate, a plurality of pedals and a plurality of supporting plates, the stair pedals and the supporting plates are arranged on the bottom plate, each pedal is perpendicular to the corresponding supporting plate, and a hollow cavity is formed between each pedal and the corresponding supporting plate; the noise absorption structure comprises a first sound absorption layer, a second sound absorption layer, a third sound absorption layer and a sound insulation layer, the first sound absorption layer, the second sound absorption layer, the third sound absorption layer and the sound insulation layer are all arranged in the cavity, the pedal is further provided with a groove and a buffer layer, an elastic block is arranged in the groove, and the buffer layer is arranged in the groove. And the buffer layer is arranged on the pedal, is attached to the elastic block and is used for directly reducing noise generated by treading. The structure provides a comprehensive soundproof effect, which means that the noise absorbing structure can be used in various scenarios, including indoor stairs, outdoor stairs, and the like.
本申请提供了一种楼梯噪音吸收结构，包括楼梯主体，底板、多个踏板和多个支撑板，多个所述楼梯踏板与多个所述支撑板均设于所述底板上，每一所述踏板垂直于每一所述支撑板并与所述支撑板之间构成一个中空的腔体；噪音吸收结构，包括第一吸音层、第二吸音层、第三吸音层和隔音层，所述第一吸音层、所述第二吸音层、所述第三吸音层和所述隔音层均设于所述腔体内，其中，所述踏板上还设有凹槽和缓冲层，所述凹槽内设有弹性块，所述缓冲层设于所述踏板上并与所述弹性块相贴合，用于直接减少踩踏产生的噪音。该结构提供了综合的隔音效果，这意味着该噪音吸收结构可以在各种场景下使用，包括室内楼梯、室外楼梯等。
