An arrangement for bridging expansion joints in carriageways, especially bridges. One or more parallel plates run at right-angles to the direction of the carriageway adjacent at the top to the surface of the carriageway. The plates are supported at the bottom on bars which run at right-angles to the expansion joint and transmit loads directly or indirectly into the edges of the joint adjacent thereto. For controlling the spacing of the plates, control cables are provided. The plates are connected to the cable runs of the control cables. The cable runs run parallel to the bars and are attached either to the load-transmitting bars themselves or to separate control bars. |
