Title:
SHOCK ABSORBING DEVICE FOR NETTED BODY FOR PROTECTIVE FENCE
Document Type and Number:
WIPO Patent Application WO/2011/065448
Kind Code:
A1
Abstract:
Provided is a shock absorbing device for a netted body for a protective fence, this shock absorbing device being such that when an impact force acts due to a rock fall, a landslide, a snowslide, or the like, the netted body is made to deform by a large amount, with the result that the impact absorption effect by the netted body can be improved. The netted body (4) comprises netted body turnup sections (24) formed in such a way that oblique wires (22), which are in the wire category, are turned up in the edge sections; and netted body intersecting sections (23) at which the oblique wires (22) intersect with each other. The netted body turnup sections (24) and the netted body intersecting sections (23) are connected, by means of shock absorbing rope members (40) and shock absorbing implements (30), to an upper horizontal rope member (11) and vertical rope members (52), both of which are connected members of the protective fence (1). When impact energy is applied to the netted body (4) due to a rock fall or the like, then the netted body turnup sections (24) and the netted body intersecting sections (23) cause the shock absorbing implements (30) to slide under friction with respect to the shock absorbing rope members (40), resulting in the impact energy being absorbed. Furthermore, because the shock absorbing implements (30) move, the deflection amount of netted body (4) can be made large, with the result that the impact energy absorption effect can be improved.
