Abstract

The invention relates to a building structure comprising a first building structure part (2), a second building structure (3), which is movable relative thereto, and at least two structural bearings (5) acting between the two building structure parts, wherein the second structural bearing (5) is a horizontal force bearing (5), which is unsuitable for transmitting vertical loads and is fixed in one axis or two axes in the horizontal direction, and comprises a first anchor structure (6) and a second anchor structure (7). At least one first guide element (17) having a first sliding surface (18) is detachably connected to the first anchor structure (6), and at least one second guide element (19) is detachably connected to a second sliding surface (20) opposite the first sliding surface (18), wherein the second anchor structure (7) and/or the at least one second guide element (19) overlaps the first building structure part (2) in the horizontal projection.

Abstract

The invention relates to a pot bearing (1) for absorbing rotations with little constraint, comprising a pot (2), an elastomer cushion (3) accommodated therein and a cover (4) projecting at least partially into the pot and supported on said cushion. Said elastomer cushion (3) is slidingly sealed off from the pot (2), around the edge beneath the cover by means of a circumferential inner seal (6), which consists entirely or at least primarily of acetal with a melt flow index (MFI 190/2,16) of less than 6g/10min.

Abstract

The invention relates to an expansion joint bridging device (1) in the form of a slat bridge transition (2) which bridges an expansion joint (4) existing between two construction work parts (3) of a traversable construction work. The expansion joint (4) is spanned by at least two crossbeams (5) which are supported in a load-bearing manner on both construction work parts (3), wherein at least one of the load-bearing supports (6) allows a displacement movement of the respective crossbeam (5) relative to the respective construction work part (3). A plurality of slats (11) arranged above the crossbeams (5) and oriented at least substantially parallel to one another are supported on the crossbeams (5) so as to be displaceable relative to the crossbeams (5) and relative to one another. An overload-safety device (17) is provided between two of the slats (11) that are displaceable relative to the crossbeams (5) and relative to one another. The overload safety device (17) 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. Between the two support profiles, at least one fixing device is acting, stabilising the relative position thereof to one another. If a threshold value for the force that would effect the two support profiles to approach one another is exceeded, the fixing device releases the positional stabilisation such that the two support profiles can be moved towards one another by displacing the fill profile upwards out of the gap.

Abstract

In order to repair a bridge in the zone of an expansion joint (3), 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. Said temporary bridging element comprises a bridging plate (17) that spans the expansion joint (3) as well as an opposite plate (20) which meshes with the bridging plate (17) in the area of a finger arrangement (21) located in the area of one of the recesses. 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 (17) is repeatedly removed and re-assembled as required.
