Patent ID: 6931807

Claim:
A bridging device for joint gaps ( 1 ) between building parts ( 2 , 3 ) including bridge parts, with an expansion joint construction ( 4 ) bridging a joint gap ( 1 ), said expansion joint construction ( 4 ) permitting position changes of said building parts ( 2 , 3 ) with respect to one another in given first limits, characterized by a safety means ( 12 ; 15 ; 34 ; 5 a ) permitting a position change of said building parts ( 2 , 3 ) with respect to one another within second limits exceeding said first limits or remaining therebelow, without a separation destroying said building parts ( 2 / 3 ) and/or said expansion joint construction ( 4 ) occurring, wherein said safety means ( 12 ; 15 ; 34 ; 5 a ) includes at least two firmly mutually connected elements which after exceeding of a defined threshold load are separated and movable with respect to one other in defined manner, and wherein one element is firmly arranged on one of aid building parts ( 2 , 3 ), whereas the other element is part of said expansion joint construction ( 4 ) or accommodates the same and said two elements of said safety means ( 12 ) being formed by a rail ( 24 ) and a slide ( 25 ), said slide ( 24 ) after exceeding of said threshold loading being displaceable in said rail ( 25 ) in order to balance shifting movements including transversal movements between bridge parts.
