Abstract: A joint filling profile for forming a joint sealing between floor slabs includes a vertical leg projecting into the joint and a profile body formed from a joint sealing compound and located in a joint widening. The vertical leg and the profile body are separated from each other with the interposition of a first separating material, wherein at least one second separating material is arranged between the vertical leg and the profile body and/or at least one reinforcing mat is arranged within the profile body. The second separating material and/or the reinforcing mat are arranged in such a way that they overlap with the first separating material at least in regions.

Abstract: The present disclosure relates generally to systems for providing a durable water-resistant and fire-resistant foam-based seal in the joint between adjacent panels. An expansion joint seal, which may be fire-resistant and/or water-resistant, is provided which includes one or more body members, a fire retardant member, which may be of an intumescent member, interspersed within the body member or members, a plurality of resilient members to provide a spring recovery force and fire resistance, and a connector of at least two of the resilient members, which connect each of the resilient members to a cover plant or may connect the two resilient members to one another.

Abstract: A crack inducer controls propagation of cracks in set concrete containing reinforcing bars. The crack inducer has an elongated, rigid core that is relatively narrow in a direction that is parallel to outer surfaces of the concrete. The core has a core width in a first plane that intersects the outer surfaces of the volume, that is at least 20% of the concrete volume width so that a crack in the volume of concrete is induced to propagate from the core and along the first plane. A plurality of spaced cross-plates are connected to the core and a water-stop may be included around part of the core.

Abstract: A device for making a connection between concrete slabs, the device having two modules derived from sheets, each module having a number of flat elements which form projections, each module further having elements in the form of a right angle, having a flat part integral with projection, and a raised part, and longitudinal members between the raised parts, and wherein the modules are assembled in such a way that the raised parts and longitudinal members of the two modules are facing each other along the two sides of a center plane, and that the projections extend on both sides of the center plane, so as to form meshing projections which pass from one side of the joint to the other.

Abstract: A crack inducer plate assembly for concrete structures having a volume and an outer surface includes an elongated and rigid core plate for extending in the volume at a location spaced from the surface, the core plate having opposite sides. A waterproof and resilient waterstop member is fixed to and covers the opposite sides of the core plate. Crossplates are welded to the core plate to anchor the core plate to reinforcing bars in the concrete. Cracks are formed in a controlled manner within the volume and by the waterstop member.

Abstract: A multi-functional, universal guide rail member is provided, for incorporation in an architectural joint system. Typically, one such guide rail member is mounted on each of two adjacent, relatively movable structures and cooperates with pivotally mounted centering bars to maintain a covering plate in centered position. The guide rail member incorporates in a single, integral unit a continuous guide groove for the centering bars, an open-sided slot for receiving fastening means (or, in some cases, caulking), and an outwardly facing slot for receiving anchoring means. The multi-functional guide rail member is usefully employed in conjunction with standard off-the-shelf structural components, such as channels and angle members, to accommodate mounting of the guide rail members in a variety of architectural configurations.

Abstract: A covering for an expansion joint is formed of a plurality of monolithic steel elements that are arranged to be self-cleaning and so as not to be subject to binding. The joint has an overall T-shape and is bilaterally symmetric. The joint includes two L-shaped portions each attached to a structural element for movement therewith. The joint cover has a steel plate on one leg of each L-shaped portion bordering the expansion gap. A spacer plate is also fixed to the leg of the L-shaped portion and forms a sealant-receiving channel with the leg and the plate. An expansion gap spanner plate slidably rests on top of the plate and a cover plate is fixed at one end to the spacer plate and slidingly engages the spanner plate to keep it in the desired position and orientation during movement of the joint.

Abstract: The present invention relates to an improved expansion joint for bridging e space between structural components susceptable to relative movement. The joint construction presents an uninterrupted transition between the structural components and is capable of compensating for vertical as well as lateral displacement of the joined parts. The device is capable of withstanding high load forces due to a novel self centering reinforcing rail.
