Abstract: A process for producing a galvanized perforated steel sheet material is described. A fully processed, unfinished sheet steel material is perforated to provide an area or areas of holes therein. The sheet material is then temper rolled to force any burrs formed during the perforation process back into the web of the material. The perforated sheet material is then galvanized. The galvanized perforated sheet material may then be roll painted without damage to the painting rolls.

Abstract: A metal fence (20) is constructed by a fence system with components including clips (26), fence posts (22) allowing rails (24) to engage with the posts and caps (21) to cover the seam between the rails.

Abstract: A continuous preset access housing formed in part by a corrugated housing member is disclosed. A corrugated decking sheet supports the longitudinally extending housing member above cells of the decking sheet and a layer of concrete is placed over the deck and housing. Openings through the concrete and housing member provide access to the underlying deck cells. Covers are provided over the openings to create fully enclosed underfloor housings to receive electrical receptacles and the like. The overall arrangement is such that the resulting system has increased flexibility, capacity and strength. Additionally, the system is more cost effective than systems which provide many individual housings.

Abstract: A deck structure is disclosed in which overlapping and interlocking corrugated members, each formed from a single sheet of metal, are covered with a layer of concrete. Each corrugated member has at least one longitudinally extending valley along one side and a substantially flat flange provided on an opposite side. The flange may include spaced-apart longitudinally extending shallow depressions spaced at a distance and configured to receive and interlock with an adjacent member. When the decking is used as a deck form, the end portions of the sheet members may be partially or completely closed. Perforations which may be provided in flange portions of the members, allow water and other liquids to drain through deck form and to be caught in a vented valley portions of an adjacent member.

Abstract: An improved cellular flooring service distribution system is disclosed comprising a cellular flooring unit in which a dividing means provides a plurality of open parallel conduits in a single valley of a corrugated sheet, an overlying trench providing a plurality of transversely oriented parallel passageways which have access to said conduits and an isolating means to selectively isolate at least one conduit and passageway from the remaining conduits and passageways. Cover means and access housings are also provided. Since the above components do not require any special fabrication, they can be efficiently and cheaply mass produced, preferably from sheet metal. Service lines may be placed in open conduits and passageways prior to covering to eliminate the need for feeding the lines through enclosed cells.

Abstract: A trenchless underfloor conduit system for distribution of electrical conductors, service lines and the like is disclosed. One or more spaced-apart duct members of reduced height dimension are placed over a corrugated deck. Covers are provided over selected valleys of the corrugated deck to provide at least one enclosed deck conduit extending transversely with respect to the ducts. Openings are provided in the deck conduit and overlying duct member to allow for communication therebetween. A substantially uninterrupted layer of concrete is provided over the deck and duct members and is secured to underlying supporting beams. The layer of concrete preferably has a minimum thickness of about two inches and is secured to the beams to increase the overall strength of the floor by utilizing a composite design without increasing the overall thickness or reducing the service line capacity thereof.

Abstract: An improved high strength cellular metal floor raceway system for distribution of service lines and the like is disclosed. Deck members are provided on upper and lower levels and present at least one uninterrupted deck conduit extending substantially horizontally on both deck levels. The deck conduit extends transversely with respect to one or more longitudinally extending beams which support the deck members. A feeder member having at least one uninterrupted feeder conduit therein extending substantially parallel with respect to the supporting beams is at least partially recessed within the upper deck level above the lower deck level. An upper surface of the feeder member is preferably provided on substantially the same vertical level as an upper surface of the upper deck level. A layer of concrete is provided over substantially the entire surface area of the conduit system.

Abstract: The specification discloses a fire resistant foam insulated building panel comprised of two skins having a cellular plastic core between them and a fire resistant coating on the interior face of at least one skin. The fire resistant coating is comprised of a film-forming organic polymer having solid, reactive ingredients distributed therethrough which will react when exposed to heat to release nonflammable gases. The gases are entrapped in the film causing it to expand into an insulating barrier up to one hundred times thicker than the original coating.

Abstract: A composite floor structure is disclosed in which a plurality of corrugated sheets having crest portions which slope downwardly at each end thereof are supported on the top surface of a plurality of spaced I-section supporting beams. Studs are welded directly to the top surface of the I-beams directly over the beam's webbing to securely connect the beams to an overlying concrete slab, thereby creating a composite action between the beam and slab and increasing the load carrying ability of the I-beams. By providing a sufficient volume of concrete around the studs, each stud is completely effective. Embossments may be provided in the sheets to also create a composite action between the sheets and the slab causing the entire structure to act as a single composite unit to resist vertical gravity loads (bending) and in plane horizontal wind or seismic loads (shear).

Abstract: A method and apparatus are disclosed for marking hot workpieces which are particularly useful in marking weld defects on hot continuous welded pipe immediately after fabrication. The method involves the application of a controlled flow of glass particles to the workpiece which melt and produce a fusion coating on the workpiece. This glossy fusion coating absorbs the iron scale, penetrates to the base metal and adheres well to the hot workpiece. The coating will remain on the workpiece during cutting, sizing and initial cooling operations. Further cooling causes the coating to crack and expose the base metal leaving a bright metal mark resembling a galvanized surface. An improved glass bead dispensing gun having a modified nozzle and marking tube is used to apply the glass particles. The nozzle and marking tube enables the user to deposit an even flow of glass particles onto the workpiece and shield the gun from the hot workpiece.

Also the core is maintained encapsulated by a plastic sheet which is uniquely connected to the edges of the outer and inner metal skins.

Abstract: A two-span wall panel construction includes a plurality of spaced, horizontal structural girts with liner panels secured between each three adjacent girts. Horizontally extending subgirts are attached to the liner panels and exterior panels are secured to the subgirts. The exterior panels are corrugated and mounted so that the corrugations extend parallel to the vertical structural columns. A plurality of notches is located on the outer surface of the exterior panel. The notches are aligned midway between the horizontal structural girts and can be varied in depth to cause the exterior panel to fail at the notch when subjected to a predetermined external load. Additional notches can be positioned on the inner surface of the exterior panel in alignment with the other notches. The adjacent, vertical liner panels are positioned in slightly spaced relationship at the end girts and the exterior panels are positioned in overlapping and unattached relationship at the end girts.

Abstract: A two-span wall panel construction includes a plurality of spaced, horizontal structural girts with liner panels secured between each three adjacent girts. Horizontally extending subgirts are attached to the liner panels and exterior panels are secured to the subgirts. The adjacent, vertical liner panels are positioned in slightly spaced relationship at the end girts and the exterior panels are positioned in overlapping and unattached relationship at the end girts. Clips for holding the liner panels are secured to the end girts between the adjacent liner panels. These clips have angular flanges which pinch the adjacent liner panels against the end structural girts. External forces of predetermined magnitude cause the liner panels to deform about the middle girt as the liner panels pivot about and release from the clip flanges while the overlapping exterior panels simultaneously pivot and release at their overlapping end.
