Definitions

  • the present invention relates to safety screens for use during building construction and, more particularly, safety screens for preventing construction workers from falling from edges of building precipices.
  • It yet a further object of the present invention to provide a construction safety screen system that can be quickly and easily installed and removed using standard tools.
  • the present invention is directed to a construction safety screen system including a flexible net member sized to cover an opening of a building, a plurality of straps attached to the flexible net member, and a plurality of snap hooks each being securable to the distal end of one of the plurality of straps and to one of a plurality of fasteners attached to the concrete building structure surrounding the opening.
  • FIG. 1 is a front elevational view of the construction safety screen system of the present invention affixed to the opposing side walls, ceiling and floor portions of a building edge surrounding a wall opening;
  • FIG. 2 is a front elevational view of the construction safety screen system of the present invention affixed to the opposing side walls and floor portions of a building edge surrounding a wall opening;
  • FIG. 3 is a side elevational view of the construction safety screen system of the present invention horizontally affixed to opposing concrete slab portions of a building edge surrounding a floor opening;
  • FIG. 4 is an isolated side elevational view, shown in partical cross-section, illustrating a fastener in connection with an oval snap hook.
  • the construction safety screen system of present invention is shown and is generally indicated as 10 .
  • the construction safety screen system 10 includes a flexible net member 12 sized to cover an opening 100 , such as a wall opening, at the edge of a building precipice, a plurality of straps 14 attached to the flexible net member 12 , a plurality of fasteners 16 , such as masonry fasteners, each being structured to be anchored to a building edge surrounding the opening 100 , and a plurality of oval snap hooks 18 each being securable to the distal end of one of the plurality of straps 14 and to one of the plurality of fasteners 16 attached to a building edge 102 surrounding the opening 100 .
  • each of the plurality of straps 14 is adjustable for allowing a user to pull the flexible net member 12 taut between the edges of the opening 100 , thereby permitting the net member 12 to be adjusted to accommodate the size of a particular opening 100 .
  • the spacing between fasteners 16 is dependent upon the tension and shear values between the fastener and the specific type of substrate (e.g., concrete slab; concrete masonry unit) to which the fastener 16 is secured.
  • the flexible net member 12 is surrounded by a flexible frame border 20 made from a resilient, flexible material, such as nylon rope.
  • the flexible net member 12 is made from a resilient, flexible material, such as polypropelyne, and may be arranged in a pattern within the flexible frame border 20 leaving gaps 23 between individual segments 21 of the resilient, flexible material.
  • the gaps in net member 12 serve to permit flow of wind therethrough for avoiding wind resistance hazards.
  • the gaps between individual segments 21 of the resilient, flexible material are sufficiently sized to prevent passage of an individual's body.
  • the flexible net member 12 includes individual segments 21 of resilient, flexible material aligned in a 2′′ ⁇ 2′′ grid.
  • the fasteners 16 are installable to the ceiling and floor portions, typically made from concrete slabs 101 , of the building edge of a wall opening 100 using a standard electrically powered drill.
  • the construction safety screen system 10 may be secured to edges 102 of opposing sidewalls at an opening 100 using fasteners 16 in connection with straps 14 .
  • a wire 22 may be used as an attachment point for securing a side of the net member 12 .
  • a turnbuckle 24 in connection with wire 22 is used for adjusting the tension of the wire 22 after installation of the wire 22 .
  • a plurality of snap hooks 18 each in connection with one of a plurality of straps 14 are releasably securable to the wire 22 .
  • Use of a wire 22 is ideal for instances wherein there is no ceiling portion to which a fastener 16 can be secured to or wherein the ceiling structure is considerably high (e.g., 25′ ceiling) or not suitable for securing a fastener 16 to (e.g., scaffolding or cat walk structure).
  • a kick plate 26 (as required by OSHA standards) is installable above the floor portion to which the fasteners 16 are secured.
  • One or more apertures 28 are included along the length of the kick plate 26 to permit passage therethrough of one of the plurality of straps 14 , which is secured to a respective fastener 16 by a snap hook 18 .
  • a net member 12 may be horizontally affixed to opposing concrete slab portions of a building edge surrounding a floor opening. For example, exposed roof and floor openings during construction can be fully covered by a net member 12 to prevent a worker from falling through the opening. As shown in FIG. 3 , the fasteners 16 must be installed at a sufficient distance away from the opening to permit overlap of the net member 12 relative to the concrete slab 100 in order to complete cover the exposed opening.
  • a fastener 16 is shown in conjunction with a snap hook 18 .
  • the fasteners 16 are 1 ⁇ 4′′ diameter, 13 ⁇ 4′′ long fasteners and the snap hooks 18 are 1 ⁇ 4′′ diameter oval snap hooks.
  • Each of the net member 12 , plurality of straps 14 , plurality of fasteners 16 , and plurality of snap hooks 18 are re-usable, making the construction safety screen system 10 of the present invention cost efficient.
  • the construction safety screen system 10 is designed to meet and exceed the standards set by the Occupational Safety and Health Administration (OSHA) standards for temporary guardrail systems.
  • OSHA Occupational Safety and Health Administration
