Abstract: A pot bearing is provided for absorbing rotations with little constraint, comprising a pot, an elastomer cushion accommodated therein and a cover projecting at least partially into the pot and supported on said cushion. The elastomer cushion is slidingly sealed off from the pot, around the edge beneath the cover by means of a circumferential inner seal, which consists entirely or at least primarily of acetal with a melt flow index (MFI 190/2.16) of less than 6 g/10 min.

Abstract: 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.

Abstract: A bridging device for an expansion joint, the expansion joint being placed between an abutment and a superstructure, comprises at least one plate that extends longitudinally of the joint, and is placed between the abutment and the superstructure, and which is supported on at least two traverses that span the expansion joint while resting upon the abutment and the superstructure. A tooth profile is placed on the top side of the plate and the teeth thereof, which point toward both sides, mesh with the teeth of teeth profiles assigned to the adjacent plates or edge profiles. Two sealing strips are connected to each plate and are detachably connected to the adjacent plate(s) or to the adjacent edge profile(s). Both sealing strips connected to the relevant plate are, in the area of the parting plane, fixed between the at least one plate and the tooth profile placed thereon.
