  • Patent number: 5442884
    Abstract: A fire-resistant wall structure is provided with a recessed corner guard, for absorbing impact forces, particularly at an external corner. To compensate for the relative loss of fire-resistance capability, in the area in which the wall structure is recessed to receive the corner guard structure, surfaces within the recess are provided with a layer of intumescent paint which, when exposed to sufficiently elevated temperature, expands to develop a thick, cellular foam providing a highly effective insulating layer. The intumescent paint is applied directly to surfaces of an extruded aluminum structural element installed in the recess. Preferably, the paint is applied at the factory where the corner guard components are manufactured. Significant economies and other benefits are realized in relation to prior practices of installing ceramic matting in the wall recess at the construction site.

  • Patent number: 5400559
    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.

  • Patent number: 5384996
    Abstract: An architectural joint system is disclosed, which incorporates a slidably supported arched cover plate to span the open space between two relatively movable structural units. The edge margins of the arched cover plate are slidably received in housings, mounted at the adjacent corners of the structural units. The housing assemblies are formed of base members and cover members assembled to define a narrow gap for the reception of a thin cover plate, and an enclosure for receiving the edges of the plate. The cover members are uniquely designed to have an outwardly and upwardly convergent taper, extending over a substantial distance of at least about two times the thickness of the cover member. The arched plate is of a shallow, upwardly convex contour, closely conforming to the long convergent taper of the cover member.

  • Patent number: 5365713
    Abstract: An elastomeric joint seal for architectural structures is provided with a multi-part cover and employs special anchoring hardware at least partially, and preferably entirely, mounted outside of the joint. The preferred mounting hardware comprises channels for receiving anchoring ribs of the multi-part cover. The main portion of the cover spans and seals the architectural joint, and is secured in the mounting hardware by anchoring ribs at each side. Cover strips are also anchored in the mounting hardware, and cover any exposed portions of the mounting hardware. The effective width of the joint is increased, by locating the mounting hardware outside of the joint space, which enables the joint to be designed to a narrower width dimension. The cover strips may be of a different color than the main seal to minimize the sight line.

  • Patent number: 5319907
    Abstract: A telescoping wall joint system is disclosed, for connecting adjacent sections of an architectural structure, while accommodating substantial relative movement, such as might result from seismic activity Extended motion is provided in the joint system while avoiding the use of excessively wide components, which are both costly and aesthetically undesirable. A center cover plate, which spans the open space between two adjacent structural units, is received along one or both sides in a tubular sleeve. The cover plate is slidably extendable within a predetermined range in the tubular sleeves to accommodate normal movements of the structural units, such as may result from thermal expansion and contraction, for example. The tubular sleeves themselves are slidably received within fixed housings mounted on the respective structural units.

  • Patent number: 5297372
    Abstract: An elastomeric seal for connecting two relatively movable architectural structures, such as floor sections, is constructed to optimize resistance to failure of the elastomeric element, in either adhesion or cohesion modes. An elastomeric seal, and an underlying support plate are provided with gently undulating, somewhat sinusoidal surface configuration, with the elastomeric element being of downwardly convex configuration and of relatively maximum thickness in its center, and of downwardly concave configuration and relatively less thickness in regions spaced on either side of center. Widthwise stretching of the elastomeric element tends to be concentrated in the regions of downwardly concave configuration, being thus not only distributed but also located away from areas of maximum vertical stress.

  • Patent number: 5224319
    Abstract: A one-piece molded or cast centering bar, for an architectural joint system, is disclosed. The centering bar, which is designed for cooperation with spaced guide rails, mounted on opposed, relatively moveable structures, has a central base section and integral arm portions extending radially therefrom in opposite directions. Integral guide means are carried at the outer ends of the respective arm portions, and engage guide grooves in the respective guide rails. The centering bar is pivotally connected to a cover plate, which spans the space between the moveable structures. As the structures move toward and away from each other, the centering bar functions in a known manner to maintain the cover plate symmetrically positioned with respect to the open space.

  • Patent number: 5187910
    Abstract: An improved fire barrier system is disclosed for interposition within an expansion joint between adjacent wall or floor members. In the disclosed embodiment, the invention is characterized in that the fire barrier system is symmetrical in both pairs of opposing quadrants defined by a first axis parallel to and midway between said mutually facing walls and transverse to said direction of elongation and a second axis transverse to said first axis and to said direction of elongation. This symmetry affords equal resistance to fire from either side of the barrier, eliminates the possibility of the joint being installed backwards, and permits the barrier system to be fire-rated for resistance to fire from either side of the barrier on the basis of a single test.

  • Patent number: 4743036
    Abstract: An elastomeric compression seal for sealing expansion grooves in bridges or the like. The seal comprises a plurality of congruently linked cells having vertical side walls and convex upper walls. The seal is characterized by a controlled collapse which prevents the convex upper walls from elongating upwardly upon lateral compression of the seal. This controlled collapse is accomplished by downwardly extending V-shaped walls connected at their upper edges to the vertical walls. As the seal is compressed, the V-shaped walls collapse such that their apexes are displaced downwardly. This downward force is transmitted to the central portion of the convex upper walls by vertical connectors to negate the tendency of the convex walls to distort upwardly upon compression.
