摘要:
A solar-battery-built-in plate-like body structure for a sound insulation wall constituted by the combination of a solar-battery-built-in structure for a sound insulation wall having a gentle convex arcuate shape so as to be installed on the top end portion of a sound insulation wall in the form of a head board, and a solar-battery-built-in structure for a sound insulation wall having a solar-battery-built-in plate-like body held by transparent plate-like materials from its opposite sides and inserted into a window-like opening portion or a wall holding frame portion formed in the sound insulation wall.

An outer mounting rail at a side opposite to a sound source side and an inner mounting rail at the sound source side are fixed to a metal securing part secured to an attachment base portion projecting from a top portion of a sound insulation wall. An outer stationary rail fixed to a sound absorbing body is fixed to the outer mounting rail by a joint bar, and an inner stationary rail fixed to the sound absorbing body is fixed to the inner mounting rail.

Fixing members (13) are mounted, at predetermined intervals, on the top portion of a footing (15) that is built along a road. A concrete-type board (2) having vertical through-holes is mounted on the footing (15) through the fixing member (11). Steel rods (7) each having top and bottom threaded portions are inserted into the respective through-holes (17) of the board (2) with the bottom threaded portions being threadedly engaged with the respective fixing members (11). Upper nuts (8) are engaged with the top threaded portions of the respective rods (7), to thereby fix the board onto the footing.
