Title:
NON-BOLTED BRIDGE PARAPET BARRIER
Document Type and Number:
WIPO Patent Application WO/2011/041292
Kind Code:
A3
Abstract:
Increased resistance to displacement of a barrier or barrier sections, thereof in response to a lateral force without anchoring or bolting harrier sections together is achieved by providing an attachment arrangement near the top of an end of barrier sections which is capable of carrying a tensile force and developing that tensile force using a tightening bolt/nυt arrangement located at deflection stops at lower comers of the barrier sections to develop a compressive force. The barrier sections are thus rigidly attached together such that a lateral force applied to one or more barrier sections is partially transferred to additional attached barrier sections effectively increasing the mass against which the lateral force is applied. The tightening bolt/nut arrangements are retained by and are captive to the respective barrier sections when barrier sections are disassembled from each other.
