Abstract: A skylight fall protection safety panel formed from a single sheet of metal having a predetermined surface area A1 and a plurality of apertures are punched out of at least one central perforated portion of the sheet having a surface area A2 surrounded by strip portions having a perimeter surface area A3. A2 is as great as or greater than 0.60A1. The shape of the apertures can take many different forms but they would have a greatest width D1 that is less than 2.0 inches. The central perforated portion has a sufficient number of apertures of a sufficient size that 50 percent of A2 is open to pass light therethrough. The sheet metal safety panel would be secured under an existing fiberglass skylight panel. The sheet panel can also be corrugated to match translucent skylight panels that are corrugated. The sheet metal panel can also be inserted into a mold or cast with a top layer of resin material and a bottom layer of resin material and also having the central perforated portion apertures filled with resin.

Abstract: A door is constructed with a separate member joined to the door edge by a tongue-and-groove coupling and screws so as to be readily removable and replaceable. The separate member sustains the impacts imparted to the door by carts or wagons pushed past the door and can be readily replaced when damaged, thus avoiding replacement of the entire door. A flexible cover snaps over the outer surface of the separate member to add impact resistance and aesthetic appeal. Intumescent strips may be inserted inside or outside of the cover to enhance sealing between the door, and at the adjacent door or door frame, thereby improving the fire resistance rating of the door. Accent strips or reveals of contrasting or complementary colors may be incorporated to add to the aesthetic appeal of the door. The door construction is of particular utility in schools, health care facilities and other institutions.

Abstract: A barrier to fluid passage is embedded within, instead of atop, porous material to retain the durability of the surface of the porous material. In one embodiment, a thin set mortar is applied to a concrete slab. A pleated metal foil is pressed into the wet mortar and a bond is established. The mortar is allowed to set and a top, or finish, section of concrete is then poured over the foil and finished conventionally. Provisions are made for sealing expansion joints in concrete slab floors and at the juncture of floor and wall. The foil may be provided in multiple layers to provide a mechanical bond via mortar oozing through perforations or along pleats in each of the top and bottoms layers, while providing a solid layer through which a fluid will not pass, at least in one direction.

Abstract: An apparatus for covering an opening of a building comprising a plurality of rectangular panels. The panels are sized such that when they are stacked for storage, the panels nest together.

Abstract: A filter assembly is provided that has a filtering screen and a skeletal structure, the skeletal structure being attached to the filtering screen. At least one of the filtering screen and the skeletal structure form a plurality of downward extending channels.

Abstract: A multi-layer wall panel includes a core filler material surrounded by two plastic sheets. Each sheet includes three-dimensional texture formed to resemble masonry or other desired aesthetics. A layer of concrete may be disposed between each sheet and the filler material. The sheet may be removed from the concrete layers to expose the concrete surfaces. Multiple wall panels may be stacked on top of one another and joined side-by-side with posts and connectors to form a wall assembly. A method for manufacturing vertical concrete wall structures is also provided.

Abstract: The present invention is directed to a flange attached to a window panel with an opening. The flange prevents an object from contacting the bottom edge of the opening as the object is passed through the opening. Moreover, the cargo rests on the flange rather than the bottom edge to prevent the cargo from damaging the window panel.

Abstract: A view panel for a raised floor system is described which is constructed by an outer rigid frame, an upper plate of a tempered glass panel and a lower plate of an apertured steel panel for providing structural support of the view panel. The invention further describes a raised floor system that utilizes such view panels installed in floor panels in a semiconductor fabrication environment.

Abstract: A structural tie shear connector for use with a concrete and insulation composite panel. The panel has a first concrete wythe, a second concrete wythe, and an insulation layer interposed between the first and second concrete wythes. The connector has two sides extending in a direction substantially parallel to a longitudinal centerline of the connector and two sides extending across the longitudinal centerline of the connector. First and second pairs of angular links are connected to the sides, and a pair of legs are connected to, and extend outward from, one side of the connector. The connector is extendable through the insulation layer and into the first and second concrete wythes to hold the panel together.

Abstract: The present invention relates to a protective device for openings in a structure, e.g., windows and doors, from storms and hurricanes. The present invention also relates to the aforesaid devices in combination with the frames of openings. The present invention device provides for removably installing protective boards in structural openings as needed, such as when tornadoes, high winds, extreme rain and snowstorms or hurricanes are threatening a building. These devices rely upon and include rotating U channels that receive the protective board, and are then shut and secured. After the threat has passed, the device is unsecured or unlatched, the board is removed from the U channels and may be stored remotely so as to not interfere with the function or view of the opening, window or door.

Abstract: The present invention provides one or more viewports formed at predetermined locations that allow inspections of an inside member of a closed wall system. The viewports can be disposed at predetermined locations that do not significantly impair the structural characteristics of the outward layers or inside members. In at least one embodiment, the viewports are formed in one or more outward layers during fabrication of a closed wall system. Generally, the closed wall system can be mass-produced in a manufacturing facility, although the closed wall system may be assembled at the job site.

Abstract: A corrugated wooden fiberboard panel system provides a new structural member for use in the construction of building walls, ceilings, and floors as a substitute for conventional framing members, such as studs and joists.

Abstract: A structural member including a web portion having a plurality of triangular regions to provide additional strength and stiffness. The triangular regions are recessed from the web and may have a floor area or the floor may be cut out to provide apertures with lip portions. An additional element secures a flanged bracing panel in the opening between the studs and the top and bottom plates of a building frame and clads both sides of the braced frame.

Abstract: Flooring systems including a metal raised access flooring panel (10) that is solid or is perforated by oval or oblong openings having major axes not parallel to any panel edge. The major slot axes may, for instance, be at a 45° angle to each panel edge. The slots (28) may be arranged in “clusters” of six slots, with one pair of slots above another pair and one slot to each side of, and mid-way above and below, the stacked pairs. Alternatively, the panels (10) may be perforated by circular holes arranged in a similar pattern. Adjacent panels may be interlocked with retractable pins extending from one panel (10) to another. Pedestal heads and stringers are adapted to accommodate panels of different sizes.

Abstract: A grill for an automobile or other vehicle is provided, and includes a plastic mesh like area designed to visually appear like a metallic wire mesh grill. The grill is substantially less costly than a metallic grill, as it is made of polymer-based plastic material.

Abstract: Core-type structures are formed by extruding elongated tubular members or sheets of a thermoplastic material that are subsequently cut into segments or plates having a defined length and then assembled into a bundle. The bundle is then simultaneously cut at a number of spaced-apart locations along the length of the bundled segments, or plates, whereby a plurality of separate core structures are simultaneously formed.
