SOUNDPROOFING WALLS

摘要

A soundproof wall is provided to minimize work in a working field by allowing a worker to easily fix a fixed frame, which is equipped with a soundproof plate, to a strut. A soundproof wall comprises a base structure(100) and a plurality of struts(200). The struts are installed on the base structure at a regular interval and have front plates(230) formed with coupling holes(220) lengthwise along the struts, respectively. Fixed frames(300) are formed with coupling grooves(330), which are fixed to the coupling holes using a screw, and have support grooves(320) at one side thereof, respectively. Each support groove has a locking protrusion(310) at the lower end thereof. Soundproof plates(400) have both sides fixed to the support grooves of the fixed frames, and have locking grooves(410) corresponding to the locking protrusions, respectively.
