Abstract: A building structure with a base unit and building unit that can be moved relative to the base unit is provided with a joint cover, which bridges a compensating joint between the building unit and base unit, supported on the building unit and on the base unit. At least one of the two support structures has sliding partners, one of which is a sliding partner paired with the building or base unit in a fixed position and the other of which is a sliding partner paired with the joint cover in a fixed position. One of the sliding partners is designed as a sliding ramp in a region such that when the sliding ramp contacts the paired sliding partner, an approaching movement of the building unit towards the base unit raises the joint cover. The sliding ramp may be designed with a continuously decreasing pitch.

Abstract: An expansion joint bridging device is provided in the form of a plate-type roadway joint which bridges an expansion joint between two building components. The expansion joint is spanned by crossbeams which are braced in a load-bearing relationship on both building components. Supported on the crossbeams is at least one plate disposed above the crossbeams, the plate having two plate portions which lie flush with one another and are interconnected in a force-transmitting relationship. The plate portions are connected in situ by means of at least one cover plate which bridges the joint between the plate portions and connects the two plate portions in a force-transmitting relationship. At least one of the connections between the cover plate and the plate portions is hinged, having a rotational degree of freedom about an axis extending horizontally transversely to the orientation of the relevant plate.

Abstract: The invention relates to a painting facility and a method for painting a workpiece, wherein, in a painting station, a coating is sprayed onto the workpiece by way of at least one painting device, and in an extraction station, which is arranged outside the painting station, air with overspray is extracted out of the painting station via an extraction device with a filter element, wherein overspray is separated out of the extracted air at the filter element. According to the invention it is provided that the exhaust air is led away via an extraction opening which is arranged in a lower region of the extraction station, wherein the filter element is placed onto the extraction opening, wherein the filter element is arranged approximately centrally in an extraction chamber of the extraction station. The invention further relates to a filter element provided for this purpose.

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.
