LIGHT WEIGHT SOUNDPROOF PANNEL AND SOUNDPROOF WALL USING THE SAME

摘要

PURPOSE: A lightweight soundproof panel and a soundproof wall using the same are provided to secure resistance against wind pressure because a weight such as steel plate is inserted in the lightweight soundproof panel. CONSTITUTION: A lightweight soundproof panel(100) comprises a main body(110), a coupling protrusion(120), a coupling groove(130), and a weight insertion part(140). The main body is formed of a lightweight material. The coupling protrusion is formed on the top of the main body to be coupled to a coupling groove of an upper soundproof panel. The coupling groove is formed on the bottom of the main body to be coupled to a coupling protrusion of a lower soundproof panel. The weight insertion part is formed inside the coupling groove to receive a weight.
