A debris containment system includes channel units that are configured to attach to perimeter structural members of the building (e.g., vertical columns and/or horizontal beams) and extend outward from the perimeter of the building. Channel units can be produced in any length or lengths needed for a given application. These channel units are used to lift and support barrier members (e.g., nets, tarps, canvas/fabric, or other barrier members) to create barriers along the perimeter of the building. Importantly, these channel units are generally attached directly or indirectly (e.g., via temporary vertical members) to structures that will remain on the building (e.g., structural columns and beams of the building) as opposed to being used with separate framing structures erected outside of the building perimeter, although in some exemplary embodiments, channel units can be used on structures erected outside of the perimeter of the building.

A safety cable system for installation during building construction is provided and includes a first track mounted to a first structural element of a building, a first plurality of anchors slidably engageable with the first track, a second track mounted to a second structural element of a building, a second plurality of anchors slidably engageable with the second track, and a plurality of cables interconnecting the first plurality of anchors and the second plurality of anchors. The first plurality of anchors, the second plurality of anchors, and the plurality of cables are positionable vertically at a plurality of different heights above a floor of the building, or horizontally at a plurality of different positions above the floor. Also provided are stops for restricting movement of the first and second plurality of anchors, roller bearings that capture the plurality of anchors in the tracks and allow the anchors to slide with respect to the tracks, plates and associated mounting hardware for mounting the tracks, turnbuckles for tensioning the cables, and tie points for tying a netting between the tie points.

An apparatus includes a first platform, a second platform disposed above the first platform, a scaffolding connecting the first and second platforms including an upper support beam, a middle support beam, and a lower support beam, and a cable attached to the upper support beam. The lower support beam supports the first platform. The middle support beam supports the second platform. The upper support beam is disposed above the second platform.

A barrier material for a containment system comprising: a first portion of polymeric material having an open structure defined by a plurality of small openings to function as a fine screen, the first portion of polymeric material being formed from a plurality of fibrous materials and being configured to form a static structure having a display surface; and a second portion attached to a second surface of the first portion, the second portion having an open structure defined by a plurality openings to function as a reinforcing member for the first portion; wherein the display surface of the first portion is configured to receive and retain a printed image thereon.

A flexible glass protective net with landscape function for falling objects and a design method thereof includes flexible support ropes, buckling clamps, articulated pieces, glass plates and seam rubber strips; the flexible support ropes are arranged crosswise in a grid shape, the buckling clamps are arranged at grid nodes, and the glass plates are arranged in the grids; the glass plate includes pieces of glass, and the pieces of glass are connected by the seam rubber strips at seams; the glass is clamped and fixed by the articulated piece, the tail end of the articulated piece is connected to the buckling clamp, and the glass plate is connected to the buckling clamp via the articulated piece; mutually crossing and separated slots are reserved in the buckling clamps, and the flexible support ropes at the grid nodes respectively pass through the slots.

A safety system for a building roof may include a plurality of anchors to be connected to the building roof at spaced apart locations, at least one frame member, a net connected to the at least one frame member, and a plurality of straps each defining a loop extending between a respective anchor and the at least one frame member, with a portion of the loop being connected to the net. The safety system may further include a plurality of standoff members to be positioned between the building roof and the at least one frame member at spaced apart locations to hold the at least one frame member away from the building roof, and disengage from the building roof when the net is under load so that the net wraps around the load and the straps hang from the anchors.

An electrically insulated trellis comprises a first array of parallel tubular members 2 and a second array of parallel tubular members 4. Each of the second array of parallel tubular members 4 is pivotably connected to a plurality of the first array of parallel tubular members 2 whereby to form a trellis 1. Each of the tubular members is formed from glass-reinforced polymer. A first set of fibres in the glass-reinforced polymer are substantially parallel and aligned in a first direction and a second set of fibres in the glass-reinforced polymer, distinct from the first set, are substantially parallel and aligned in a second direction different to the first direction.

A system for substantially enclosing the periphery of a building top with a netting system which is easily and efficiently movable or reconfigurable during the building construction process comprises a lightweight netting system for extending above a completed work area or floor, a strong lightweight structural support system for the netting, wherein the structural support system is vertically adjustable via slidable engagement with brackets attached to the floors which are already completed, provides enhanced safety for workers and for pedestrians below by preventing passage of workers or debris through the netting and enhances efficiency of construction by providing an easily reconfigurable, inexpensive and lightweight system for providing such enhanced safety.

A vertical raising safety rail. The safety rail includes lower linkage arm assemblies that are connected to a base and to a center rail assembly and configured to raise or lower the center rail assembly relative to the base when a rotational force is applied to the drive shaft. The safety rail also includes upper linkage arm assemblies that are connected to the center rail assembly and to a top rail. The upper linkage arm assemblies are connected to corresponding lower linkage assemblies and are configured to move the top rail relative to the center rail assembly. When the top rail is raised, one or more safety curtains are unfurled from a take-up roller inside the top rail to provide a safety curtain in the vertical plane of the safety rail.

In various representative aspects, a netting structure is configured to serve as a safety net used on construction sites to catch debris or construction personnel from falling to the ground. The netting structure eliminates the need to use a metal cable along the perimeter of a beam to support the net that typically requires the net to be clipped to the cable in several locations along its perimeter. An assembly for guiding the ropes used to pull the netting structure in place and secure the netting structure to a building frame is also provided.
