Abstract: A support structure for supporting loads on a sloping metal panel roof includes first and second side rails, an upper diverter, and a lower closure. An upstanding web of the upper diverter extends upwardly from the panel flat. An elongate lower flange extends from the upstanding web and is disposed against the metal roof panel. Opposing rib mating webs are on opposing sides of the lower flange. On a first side of the lower flange, a diversion leg of the lower flange is between the upstanding web and one of the rib mating webs. On the second side of the lower flange, the second rib mating web meets the upstanding web. The lower flange extends from the upstanding web to a distal end thereof up-slope of the lateral leg. The lower flange and the first and second rib mating webs can, collectively, define a common distal end of the upper diverter.

Abstract: This invention provides suspension fabric product, methods of making such product, and methods of installing such product, in fall protection systems used in metal building construction. The fabric product is presented Z-folded on a core, with essentially all surface air removed, and wrapped in a protective plastic wrapping which extends into the roll alongside outer layers of the roll of fabric. Essentially all surface air is removed from the Z-folded fabric at a compression station as the roll is being fabricated. Use of the roll includes extending a shaft through the core, elevating the roll to a working height at the roof elevation, temporarily mounting the shaft to existing roof structural members of the building being constructed, and drawing a leading edge of the fabric from the roll and along a run of the space between next adjacent ones of the purlins and across the space between first and second ones of the rafters.

Abstract: A roof load support structure supports a load on a roof such that substantially all of the load is conveyed through rails, which are mounted on roof panel ribs, thence through roof panel ribs, and to underlying building support structure. The panel flat between the rails can be unobstructed such that water can flow freely down the panel flat between the rails; or end closures can close off access to the respective panel flat between the end closures and the rails. One such end closure can be an upper diverter at an up-slope end of the support structure. A lower edge of such upper diverter, e.g. at the panel flat, can slope downwardly across a width of the respective roof panel thereby to direct water laterally across the respective roof panel.

Abstract: This invention provides fall protection systems, in metal building construction, and methods of installing such systems. A given such system comprises a suspension fabric, supported by a grid-work of longitudinal and lateral support bands. At least one of the lateral support bands is a relatively softer steel having greater elongation properties, while having lower yield and tensile strengths. The balanced properties better distribute the force of a falling object to the respective members of the fall protection system so as to limit the force which must be tolerated by the suspension fabric, such that the system can catch and hold a dropped test load, or a worker falling onto such system, without catastrophic failure of the suspension fabric.

Abstract: A building roof structure includes rafters, purlins, braces, and a suspension fabric. The suspension fabric, which may be part of a fall protection system, insulation support system, and/or vapor barrier system, extends across a bay or other portion of the roof structure such that the suspension fabric is above the rafters and below the purlins. The braces connect at least some of the purlins to at least some of the rafters, and each brace extends through a corresponding slit or other opening in the suspension fabric. Brace covers are provided for some or all of the braces to conceal the fabric opening, to facilitate sealing around the brace near the fabric opening, and/or to provide support for the suspension fabric near the fabric opening.

Abstract: This invention provides fail protection systems comprising a suspension fabric, supported by a grid-work of longitudinal and lateral bands, in metal building construction. The fall protection system uses the combination of relatively softer banding, a safety band spaced a particular distance from each rafter, and safety clips to attach the safety bands to the intermediate purlins, thus to distribute the force of impact of a load, falling close to a rafter, to better absorb and dissipate the force of the impact, including distributing the impact of the failing load over a greater area of the roof structure. The invention further provides methods of making elements of such systems, methods of installing elements of such systems, and buildings embodying such systems.

Abstract: This invention provides fall protection systems, in metal building construction, and methods of installing such systems. A given such system comprises a suspension fabric, supported by a grid-work of longitudinal and lateral support bands. The distance of the safety band from the rafter corresponds to about 40 percent to about 75 percent of the diameter of the bag. Thus for a 30-inch diameter bag, the distance between the edge of the rafter and the middle of the safety band is about 12 inches to about 23 inches. The safety band protects the suspension fabric from being cut by the near edge of the rafter when a falling object impacts the fall protection system near the edge of the rafter.

Abstract: This invention provides fall protection systems, in metal building construction, and methods of installing such systems, a given such system comprising a suspension fabric, supported by a grid-work of longitudinal and lateral support bands. The fall protection system uses safety clips to attach lateral bands to intermediate purlins, such that the safety clips accommodate flow-through longitudinal movement of the lateral bands through the safety clips. The invention further provides relatively softer, more extensible, support bands. The system, using the softer support bands, in combination with the flow-through longitudinal movement of the safety bands through the safety clips, distributes the impact of a falling load over an increased number of members of the structural members of the building resulting in enhanced capacity for the fall protection system to catch and hold falling loads.

Abstract: A load support structure supports a load on a metal panel roof, such that substantially all of the load is conveyed through rails, which are mounted on roof panel ribs. Lateral closure members extend about, and define, the load support structure. Cavities are provided in the lateral closure members. Thermal breaks extend upwardly from the roof opening, through the tops of the closure members. Such thermal breaks are provided by a combination of thermal product in the closure member cavities and by strategic placement of edge portions of underlying roof insulation.

Abstract: Fall protection systems, methods of installing such systems, and buildings embodying such systems. Such fall protection system extends from structure elements of the building about an encompassed space into which there is risk of a person falling. An open-mesh web is supported from the structure elements and overlies, and extends across, the space. A perimeter band extends about the encompassed space. The perimeter band is secured to the building structure elements about the space and thus entraps the web between the band and the building structure elements. The web may also be supported in the space by supplemental supports, which can be crossing support bands, attached to the structure elements, or intervening e.g. walls within the space. The web is left in place and is covered by internal finish materials whereby the web is captured between internal finish materials and ceiling and/or floor members in the finished building.

Abstract: A roof load support structure supports a load on a sloping metal panel roof such that substantially all of the load is conveyed through rails, which are mounted on roof panel ribs, thence through the roof panel ribs, and to underlying building support structure. Minor portions of the load can be conveyed through an upper diverter and a lower closure. The upper diverter diverts water laterally away from the support structure, in two opposing directions to two opposing sides of the support structure.

Abstract: A load support structure supports a load on a metal panel roof. Such load support structure includes multiple closure members including opposing side rails, and optionally end closures. The rails are mounted on roof panel ribs. Cavities can be disposed inwardly of the outer perimeter of the support structure as defined by the closure members, in upper portions of the closure members. Rods may be inserted through slot-shaped openings, into the cavities. Cross-section dimensions of the rods are less than the widths of the cavity openings. Either the rods are compressed, or the cavity openings are expanded, or both, so as to enable manually inserting the rods into the cavities. Elongate thermal breaks may be installed at and adjacent the cavities, to assist in controlling thermal conduction through the closure members, between the outside environment and the enclosed space above the roof opening.
