LOAD REDUCING TYPE SOUND BARRIER UNIT PLATE, AND LOAD REDUCING TYPE SOUND BARRIER FORMED BY SAME

摘要

A load reducing type sound barrier unit plate, and a load reducing type sound barrier formed by the same. The load reducing type sound barrier unit plate comprises a unit plate body (2), and comprises lap joint parts (1) that are disposed at two ends of the unit plate body (2) respectively and that are used for the mutual lap joint of the upper and lower adjacent load reducing type sound barrier unit plates. The unit plate body (2) is a hollow housing formed by sequentially and fixedly connecting a sound absorption wall (21), an upper wall (23), a sound isolation wall (22) and a lower wall (24). The upper wall (23) and the lower wall (24) are of curved-surface structures. Each lap joint part (1) is a housing having an opening end. Two ends of the unit plate body (2) are respectively inserted into the corresponding lap joint parts (1) from opening ends. The load reducing type sound barrier reduces noise and prolongs the service life of the sound barrier.
