張出歩道ブロック
Document Type and Number:
Japanese Patent JP6373163
Kind Code:
B2
Abstract:
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
