Cover assembly for structural members

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.

20200263422 · 2020-08-20 ·

An edge protection system for use with concrete flooring, including an initial edge unit having a first part and a second part, the first part for coupling to an edge portion of a first concrete flooring panel and the second part for coupling to an opposed edge portion of a second, neighbouring, concrete flooring panel, the system also including an angled edge unit having a first part and a second part, the first part for coupling to another edge portion of the second concrete flooring panel and the second part for coupling to an opposed edge portion of a third, neighbouring, concrete flooring panel, and a modular intersection part at an intersection of the first to third panels, wherein the modular intersection part is adapted to be coupled to the initial edge unit with the initial edge unit extending radially from the modular intersection part in a first direction, and wherein the modular intersection part is adapted to be coupled to the angled edge unit with the angled edge unit extending radially from the modular intersection part in a second direction at an angle to the first direction.

Helically-packaged expansion joint seal system with flexible packaging member

A foam-based expansion joint seal system packaging which facilitates transport and reduces the need for internal splices which includes laterally-flexible packaging bodies. The packaging bodies may include flutes, corrugations or prisms on their exterior to enable lateral bending of the foam-based expansion joint seal system packaging, even into coils.

EASILY RENNOVATED EXPANSION JOINT FOR A CONCRETE SLAB FORMWORK SYSTEM
20200190746 · 2020-06-18 · ·

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).

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.

Expansion joint system

An expansion joint system includes: a core; and water resistant coating on the core. The core and the water resistant coating forming an elongated section, the elongated section configured to be oriented between substrates. The expansion joint system further includes a termination section located at one end of the elongated section and comprising a flared end forming an angle with the elongated section and configured to direct fluid and/or particles and/or solvents away from the expansion joint system.
