Abstract
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.
Claims13
A safety barrier system for use in multi-story building construction or maintenance comprising:
- at least one elongated safety barrier net which is capable of extending from the proximity of the edge of a substantially completed floor, deck or slab of a building structure and projecting upwardly to a higher level above the level of the edge of a superimposed higher floor, deck or slab of the structure to provide a safety barrier for workers located at said higher level and to provide a barrier to prevent debris from falling from the higher or adjacent levels, wherein said superimposed higher floor, deck or slab is at a predetermined height above said substantially completed floor, deck or slab, wherein said safety barrier net is flexible, wherein said safety barrier net is fixedly attached to flanges projecting from at least two vertical support members such that the barrier net is held in place substantially parallel to the exterior plane of the building to be constructed or which is being maintained, each said vertical support member being slidably engaged with a bracket structure and wherein said bracket structure is fixedly attached to an outer edge of a floor, deck or slab of said building structure, wherein said vertical support member is slidably engaged with a portion of said bracket structure which extends past the edge of said floor, deck or slab, wherein said superimposed higher floor, deck or slab is either a future floor or slab to be constructed or is incomplete, wherein said vertical support member is configured for slidable engagement with the bracket structure via two opposing guides which engage two substantially opposing flanges of the vertical support member such that the flanges are guided by the bracket structure as the vertical support members are raised to move up the building structure as construction proceeds and floors are added, wherein said bracket structure is comprised of at least two separate bracket members situated at two different floors, decks or slabs immediately adjacent each other so as to guide a vertical support member during vertical repositioning of said safety barrier system and to hold the vertical support member in position during building construction or maintenance, wherein said bracket members are comprised of releasable scissor mechanisms comprising opposing arms which facilitate releasable attachment of a bracket to a vertical support member, said releasable attachment functionality being provided by allowing the opposing arms of the bracket to be opened substantially horizontally in opposing directions on either side of a vertical support member and wherein each of said opposing guides is attached to or integral with the opposing arms of the bracket, wherein the barrier net is comprised of a border rope that supports a heavy debris liner comprised of strands, twine or rope having approximately 3/16 inch diameter or greater spaced approximately 4 to 6 inches center to center, a fine liner comprised of strands, twine or rope having approximately ½ the diameter of the heavy debris liner spaced approximately ¼ inch center to center and an approximately 2 inch wide or greater heavy duty strap placed approximately every two feet horizontally, thereby forming a triple layer safety net to stop construction debris from falling or blowing off said higher or adjacent levels of a building during construction operations.
A safety barrier system for use in multi-story building construction or maintenance comprising:
- at least one elongated safety barrier net which is capable of extending from the proximity of the edge of a substantially completed floor, deck or slab of said building structure and projecting upwardly to a higher level above the level of the edge of a superimposed higher floor, deck or slab of the structure to provide a safety barrier for workers located at said higher level and to provide a barrier to prevent debris from falling from the higher or adjacent levels, wherein said superimposed higher floor, deck or slab is at a predetermined height above said substantially completed floor, deck or slab, wherein said safety barrier net is flexible, wherein said safety barrier net is fixedly attached to flanges projecting from at least two vertical support members such that the barrier net is held in place substantially parallel to the exterior plane of the building to be constructed or which is being maintained, each said vertical support member being slidably engaged with a bracket structure and wherein said bracket structure is fixedly attached to an outer edge of a floor, deck or slab of said building structure, wherein said vertical support member is slidably engaged with a portion of said bracket structure which extends past the edge of said floor, deck or slab, wherein said superimposed higher floor, deck or slab is either a future floor or slab to be constructed or is incomplete, wherein said vertical support member is configured for slidable engagement with the bracket structure via two opposing guides which engage two substantially opposing flanges of the vertical support member such that the flanges are guided by the bracket structure as the vertical support members are raised to move up the building structure as construction proceeds and floors are added, wherein said bracket structure is comprised of at least two separate bracket members situated at two different floors, decks or slabs immediately adjacent each other so as to guide a vertical support member during vertical repositioning of said safety barrier system and to hold the vertical support member in position during building construction or maintenance, wherein said bracket members are comprised of releasable scissor mechanisms comprising opposing arms which facilitate releasable attachment of a bracket to a vertical support member, said releasable attachment functionality being provided by allowing the opposing arms of the bracket to be opened substantially horizontally in opposing directions on either side of a vertical support member, wherein each of said opposing guides is attached to or integral with the opposing arms of the bracket, wherein each of said vertical support members comprises an elongated hollow cylinder, a cross-section of the elongated cylinder having an uninterrupted circular inner contour and a circular outer contour interrupted by four equally-spaced radially-projecting flanges integrally joined to the elongated cylinder of the vertical support member, at the outer contour of the elongated cylinder, at substantially 90 degree intervals about the circumference of the elongated cylinder, the vertical support member being capable of joining end-to-end to a second vertical support member, one above the other, by means of one or more structural end joint members, wherein the elongated hollow cylinder has a length and a diameter, wherein said length is significantly longer than said diameter, and wherein the flanges extend substantially the entirety of said length.
