Abstract
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). The expansion joint construction (4) permits position changes of the building parts (2, 3) with respect to one another. A safety construction (12, 15) is provided which permits a position change of the building parts (2, 3) with respect to one another without a separation destroying the function of the bridging device. The safety construction (12, 15) comprises at least two mutually firmly connected elements which upon exceeding of a defined threshold load are separated and movable with respect to one another. One element is firmly arranged on one of the building parts (2, 3) and the other element is part of the expansion joint construction (4) or receives the latter. The two connected element are defined by a rail (24)and a slide (25). The slide (24) is displaceable in the rail (25) in order to balance shifting movements including transversal movements between bridge parts.
