An expansion joint system for bridging an expansion joint gap between two spaced-apart, underlying building or roadway structures. The expansion joint system includes a cover plate, at least one swing arm, sliding bearings engaged with the swing arms, and fasteners for engaging the swing arms to the cover plate. The swing arms include a receiving well configured for receiving a mechanical fastener to fasten the swing arms to the cover plate. The expansion joint system permits movement in response to a seismic or thermal event that causes expansion or contraction of the gap between structural members while maintaining coverage of the gap, and following a seismic or thermal event, the maintains a substantially-centered position of the cover plate.

An expansion joint (1) for a concrete slab formwork system, said joint comprising first and second longitudinal elements (2, 3), arranged side-by-side in the same horizontal plane, and intended to each form an integral part with an upper and horizontal edge of a concrete slab, the first and second longitudinal elements (2, 3) comprise arrangements (5, 6, 7) opening on their upper horizontal walls and enabling at least a portion (2a, 3a) of each of the first and second longitudinal elements (2, 3) to be withdrawn for replacement thereof. The first longitudinal element (2) comprises a stack of three layers of material (2a, 2b, 2c), with an intermediate layer (2b) having a smaller width than that of the two other layers (2a, 2c) such that the first longitudinal element (2) has a U-shaped cross-section, and the second longitudinal element (3) comprises a stack of three complementary layers of material (3a, 3b, 3c), with an intermediate layer (3b) having a larger width than that of the two other layers (3a, 3c) so as to form a transverse projection that is able to fit in the recess of the U-shape of the first longitudinal element (2).

A system for creating a durable seal between adjacent panels, including those which may be subject to temperature expansion and contraction or mechanical shear having a cover plate, a rail, and an elastically-compressible core adjacent the rail.

An illustrative example embodiment of a concrete joint insert includes a body having two ends, two longitudinal edges between the ends and two side surfaces between the longitudinal edges. A sealant is secured to one of the longitudinal edges so that the insert and the sealant can be simultaneously installed at the location of a concrete joint.

An edge protection system for use with concrete flooring, including a first part for coupling to an edge portion of a first concrete flooring panel and a second part for coupling to an opposed edge portion of a second, neighbouring, concrete flooring panel, wherein the protection system is provided in modular lengths, and wherein adjacent modular lengths are coupled by one or more bridging pins.

A foam-based expansion joint seal system packaging which facilitates transport and reduces the need for internal splices.

A foam-based expansion joint seal system packaging which facilitates transport and reduces the need for internal splices.

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.
