PROBLEM TO BE SOLVED: To provide a wall structure improved in sound insulating property, reduced in weight and attaining simplification and cost reduction of mounting work in the field.SOLUTION: The wall structure made of FRP and installed erectly includes a box structure formed with a thin space between a pair of skin face plates 3a, 3b made of FRP and arranged facing each other with a space in a longitudinal direction with the sound source side as the front side, and fixed parts 11 are provided at the lower end. The box structure includes opening plates 2a, 2b each formed with a plurality of openings penetrating a longitudinal direction y. The box structure is thus formed including the opening plates 2a, 2b to lengthen the height to thereby improve sound insulating property. The box structure is formed having the thin space to reduce weight and to simplify mounting work. Further, the wall structure is provided with mounting parts at the lower end and installed erectly to attain simple constitution and cost reduction. |
