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 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: In order to repair a bridge in the zone of an expansion joint initially at least the near-surface components of the bridging device that is to be replaced are dismounted and the existing lane structure in the zones bordering the bridging device that is to be replaced is removed in the areas facing the abutment and the superstructure so as to form recesses placed at a lower level than the lane surface, whereupon a temporary bridging element located at the ground level is removably mounted. In order to entirely dismount one section of the bridging device that is to be replaced after another and perform preparatory work for assembling a new permanent bridging device, at least the bridging plate is repeatedly removed and re-assembled as required.

Abstract: A bridging device for an expansion joint arranged between an abutment and an overhang in a traveling construction. The abutment and overhang are provided with recesses adjacent to the expansion joint, the recesses being filled with polymer concrete, and wherein a retaining section of a metallic edge profile is respectively embedded therein. An elastic sealing profile extends between the two edge profiles and is sealingly connected to the two edge profiles. A toothed profile is connected to each edge profile on the surface thereof, wherein the surface thereof terminates with the surface of the polymer concrete and the lining of the roadway and whose teeth engage with the other respective toothed profile.

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.

Abstract: A device for parking two vehicles one above the other has a support structure to house the vehicles, guide rail means in said support structure and movable vertically therein for shifting of a vehicle into an upper position in the support structure, and a vehicle-holding device to receive the vehicle to be moved to the upper position, the vehicle-holding device being carried by and movable along the guide rail means.

Abstract: A parking platform for automobiles in which the flooring is supported by cross members secured at each end to struts having vertical walls, the ends of the struts of which the flooring is comprised are turned down into slits in the transverse members. The flooring is held down by a plate which bridges the ends of adjacent flooring strips the plate being secured to a stirrup within the transverse members.

Abstract: A device, for compressing refuse and carrying away the compressed refuse in containers, of the kind including (i) a bulk container having on its upper side a charging opening, (ii) a pressure plate for compressing refuse in that part of the bulk container forming a compressing space, (iii) a lifting system for raising compressed refuse in front of an ejection opening, and (iv) a discharging device located above the compressing space, characterised in that said lifting device is a cage open on the charging and discharging sides.
