SOUND ABSORPTION TYPE PANEL USING LIGHTWEIGHT CELLULAR CONCRETE

PURPOSE: A sound absorption type panel is provided to accomplish improvements enabling the panel to be assembled and constructed in a simple method while eliminating the problem of surface corrosion of a metal plate caused by a smoke and dust. CONSTITUTION: A panel comprises a block body(5) having upper and lower ends thereof tilted in a predetermined width, a groove formed between the upper and lower ends, and which is arranged within an I-type beam installed at a predetermined spacing at a road side wall, a protrusion formed in lengthwise direction at an inner surface of the groove so as to support a sound absorption member from the groove, or a rubber plate(3) having a predetermined thickness and which is installed at an inner surface of the groove with a predetermined spacing, and a plurality of sound absorption members(1) arranged at upper and lower inner surface of the groove and which are made up of a porous lightweight cellular concrete for absorbing noise generated from the road side. The sound absorption members are assembled to a metallic rear surface of the panel. The lightweight cellular concrete is obtained by adding a foaming agent to a power consisting of cement, lime and silicate and performing a steam curing or a high temperature high voltage steam curing.
