OVERHANGING SIDEWALK BLOCK
PROBLEM TO BE SOLVED: To provide an overhanging sidewalk block that does not require widening of an excavated width of an existing road at a time of construction, and mitigates a bias in loads exerted on a substructure.SOLUTION: An overhanging sidewalk block includes: a main body block 10 comprising an anchoring deck slab 11, a side wall plate 12 erected on a top surface of an outer edge of the anchoring deck slab 11, and an overhanging floor slab 13 joined on an outer surface at a top edge of the side wall plate 12; and a rear surface plate 20 inclined toward a road side from an inner edge part of the anchoring deck slab 11, the rear surface plate allowing an angle of inclination to be adjusted. Since a load of a backfill material is exerted not only on the anchoring deck slab 11 but also on the rear surface plate 20 inclined toward the road side, a center of gravity of an overhanging sidewalk block A shifts toward the road side, thereby mitigating a bias in loads exerted on a substructure. The rear surface plate 20 only needs to be inclined to suit an inclination of excavation at a time of construction, thereby eliminating a need to widen an excavated width of an existing road due to the rear surface plate 20 installed.SELECTED DRAWING: Figure 1
【課題】施工時に既設道路の掘削幅を広くする必要がなく、しかも下部構造物にかかる荷重の偏りを低減できる張出歩道ブロックを提供する。【解決手段】定着底版１１と、定着底版１１の外縁上面に立設された側壁版１２と、側壁版１２の上端外面に連接された張出床版１３とからなる本体ブロック１０と、定着底版１１の内縁部から道路側に傾斜し、傾斜角度を調整可能に設けられた背面板２０とを備える。定着底版１１に加えて道路側に傾斜した背面板２０にも裏込め材の荷重がかかるので、張出歩道ブロックＡの重心が道路側に移動し、下部構造物にかかる荷重の偏りを低減できる。また、施工時には、背面板２０を掘削勾配に合わせて傾斜させればよく、背面板２０を設けることにより既設道路の掘削幅を広くする必要がない。【選択図】図１
