A device for assisting to secure a bridge support bracket to a beam, the device comprising: a support frame, a hook to secure the support frame to the beam, a clamp to grasp and hold the bracket, and a pivot axle to pivotally connect the clamp to the support frame. With this device, a bridge builder can use the clamp to grasp and hold the bridge support bracket, and then pivot the clamp and support frame relative to the support frame.

A modular expansion joint system with equidistance control. The modular expansion joint system includes transverse vehicle load bearing members which are positioned in a gap defined between adjacent spaced-apart structural members, support members positioned below the transverse vehicle load bearing members and extending across the expansion joint gap between the adjacent structural members, means positioned within the structural members for controlling movement of the support members, and means for controlling the spacing between the transverse vehicle load bearing members. The means for controlling the distance between the transverse vehicle load bearing members comprises a non-elastomeric compressive member, such as at least one coil spring which, which according to certain illustrative embodiments, maintains a substantially equal distance between transverse vehicle load bearing members.

A bridging device in center girder construction for a building joint between two building components having at least two edge girders and at least one center girder arranged between the edge girders and on at least one cross member bridging the building joint that each have a cross member bearing for bearing the cross member on the respective building components at their lateral ends. The object of the present invention is to provide a novel bridging device that is formed in particular space-saving. The initially described bridging device has a cross member having at least two cross member segments arranged along a longitudinal axis of the cross member and arranged displaceable relative to each other toward the longitudinal axis, so the length of the cross member is variable.

An expansion joint system for bridging an expansion joint gap between two spaced-apart, underlying building or roadway structures. The expansion joint system includes a cover plate, at least one swing arm, sliding bearings engaged with the swing arms, and fasteners for engaging the swing arms to the cover plate. The swing arms include a receiving well configured for receiving a mechanical fastener to fasten the swing arms to the cover plate. The expansion joint system permits movement in response to a seismic or thermal event that causes expansion or contraction of the gap between structural members while maintaining coverage of the gap, and following a seismic or thermal event, the maintains a substantially-centered position of the cover plate.

A roadway joint device for providing a drivable joint section between a road and an adjoining structure, particularly a bridge structure, includes at least one joint element placed on a sliding surface adjacent to the bridge structure. A longitudinal axis of the joint element is arranged substantially parallel to a plane of the roadway and a bridge end section of the bridge structure. Joint gaps with a specified gap width are arranged between the joint element and the adjoining bridge end section and/or an adjoining retaining device arranged at a distance to the bridge end section. The joint element is attached to at least one rod, the rod being arranged substantially in the direction of the longitudinal axis of the bridge structure, anchored at one rod end in the bridge structure and another rod end thereof in the retaining device.

Disclosed are an easily maintainable assembly-type bridge expansion joint structure and a construction method thereof. The easily maintainable assembly-type bridge expansion joint structure, comprising: a to-be-connected bridge beam end, wherein a number of the to-be-connected bridge beam end is two, and a groove platform is provided on each of the two beam ends in an extending direction of a gap; a connecting box body, wherein a number of the connecting box body is two, each of the two connecting box bodies is fixedly arranged on the groove platform of the beam end, and a box chamber is provided on opposite side surfaces of the two connecting box bodies respectively, a plurality of box chambers are provided, which are open opposite each other, and the box chamber is provided in the extending direction of the gap; a side beam, wherein a number of the side beam is two.

An expansion joint bridging device which bridges an expansion joint between two construction work parts of a traversable construction work. The expansion joint is spanned by at least two crossbeams which are supported in a load-bearing manner on both construction work parts, wherein at least one of the load-bearing supports allows a displacement movement. An overload safety device comprises two supporting profiles at a distance from one another and supported on the crossbeams, and a fill profile bridging the gap between the support profiles. If a threshold value for the force that would effect the two support profiles to approach one another is exceeded, a fixing device releases the positional stabilization such that the two support profiles can be moved towards one another by displacing the fill profile upwards out of the gap.
