BRIDGE PROTECTIVE BOARD
To provide a bridge protective board in which a sound absorbing material is arranged in a state where both high strength and easy replacement of the sound absorbing material are achieved.SOLUTION: In a bridge protective board 1 in which a protective board base material 10 formed by an aluminum extruded profile having at least a lower surface formed into a flat shape is arranged between girders of a bridge so as to be perpendicular to the girder in a longitudinal direction, and that is arranged between the girders of the bridge in a state where width direction ends of the protective board base material 10 are connected to each other, the bridge protective board comprises a housing 20 fixed in a state of being engaged with an engaging recessed and projected threads 17 provided along a lower surface 12 of the protective board base material 10 in the longitudinal direction. The housing 20 has a plurality of air holes 24 on a lower surface of the housing 20 and comprises a storage unit 20a of a sound absorbing material 30 inside the housing 20.SELECTED DRAWING: Figure 7
【課題】高強度と吸音材の交換容易性を両立させた状態で吸音材を配置させた橋梁防護板を提供する。【解決手段】少なくとも下面が平坦状のアルミニウム製押出形材にて形成される防護板基材１０を橋梁の桁間に当該桁の長手方向と直角に配置すると共に、防護板基材１０の幅方向端部が互いに連結された状態で橋梁の桁間に配置される橋梁防護板１において、防護板基材１０の下面１２に長手方向に沿って設けられた係合凹凸条１７に係合された状態で固定される筐体２０を具備する。筐体２０は、該筐体２０の下面に複数の空気孔２４を有すると共に、該筐体２０の内部に吸音材３０の収納部２０ａを具備する。【選択図】 図７
