DETAILED DESCRIPTION

An anchoring assembly and method of suspending scaffolding brackets using the assembly will now be described with reference to FIG. 1 through 7. The anchoring assembly consists of lengths of resilient material, preferably lengths of strapping 14, and attachment members, such as a pin 20 and cotter pill 26 combination, staples, nails or clamps, for example, but not limited to.
Referring to FIG. 2 and FIG. 3, as well as FIG. 4 and FIG. 5, the method consists of a first step of securing to a structure (such as wall 12), lengths of strapping 14 having a load rating sufficient to support a scaffolding bracket 16 to be suspended. A second step involves attaching scaffolding bracket 16 to length of strapping 14. It will be appreciated that a scaffolding installation will always involve more than one scaffolding bracket 16, each of which will be attached in a similar manner. There are various ways in which scaffolding bracket 16 may be attached to length of strapping 14. It is preferred that each length of strapping 14 be formed into a loop 18. This enables scaffolding bracket 16 to be attached to loop 18 by inserting an attachment member (such as pin 20) through loop 18. Pin 20 has a head 22, which engages a vertical support 24 of scaffolding bracket 16 to prevent its removal in a first direction. A cotter pin 26 is inserted through an aperture 28 of pin 20, to prevent its removal in a second direction. Referring to FIG. 1, vertical support 24 may have part of an outer face 27 tapered off near the end of support 24 that strapping 14 attaches to. Face 27 is the side of vertical support 24 that is positioned parallel to, but not facing, wall 12. In addition, the sides adjacent to face 27 may be tapered along with face 27 to allow space for pin 20 to be easily inserted through loop 18. When suspended in accordance with the method, the installation with scaffolding brackets 16 secured to strapping 14 will appear as shown in FIG. 1. It will be understood that in addition to vertical support 24, scaffolding bracket 16 will include a support surface 29, railings 31, a horizontal frame 33 and railing supports 35 that provide a measure of fall protection. Support surface 29 provides a space for workers to stand. Horizontal frame 33 projects horizontally from vertical supports 24, providing structural integrity for supporting support surface 29. Railing supports 35 have stirrups 37, railing supports 35 projecting vertically from the corners of frame 33. Stirrups 37 are provided to hold railings 31 in place between railing supports 35, giving scaffolding bracket 16 structural rigidity and strength. By rigidly securing railings 31, vertical supports 24 are held square against wall 12. In addition, each of vertical supports 24 may be provided with a pad 39 as shown in FIG. 1. Pad 39 is positioned between vertical support 24 and wall 12, resisting vertical and horizontal movement and aiding in the proper positioning of vertical support 24. on wall 12.
The manner of attaching loop 18 to wall 12 will vary depending upon whether the wall is a masonry wall or wooden wall, and depending upon the height at which attachment is required. Referring to FIG. 2, wall 12, as illustrated, is a masonry wall and loop 18 is being secured part way up wall 12. Referring to FIG. 3, this is done by boring a hole 34 through wall 12. Loop 18 is then extended through hole 34. A bracing member 36 is inserted through loop 18 to prevent it from being pulled through hole 34. Pin 20, which is the form of attachment member illustrated, then connects scaffolding bracket 16 to loop 18. Referring to FIG. 4, wall 12, as illustrated, is a wooden wall and loop 18 is being secured at the top of wall 12. Referring to FIG. 5, strapping 14 is positioned on top of wall 12 and nails 38 are driven through strapping 14 into wall 12 to hold strapping 14 in place. Depending upon the weight associated with the installation, it may be advisable to position a board 40 over strapping 14 and drive nails 38 through board 40 into wall 12. The purpose of board 40 is to distribute the force holding strapping 14 in place and reduce point loading on strapping 14 where nails 38 penetrate. A combination of these two approaches may also be used.
Advantages:
The method described above is simple, effective and relatively inexpensive. When the installation is taken down, length of strapping 14 is disposed of. This may be accomplished by cutting strapping 14 and removing it. Where space is of concern, the use of length of strapping 14 to anchor scaffolding requires much less space than other scaffolding anchoring systems.
Variations:
It will be appreciated that length of strapping need not be formed into a loop. Referring to FIG. 6, there is illustrated a clamp 30 which could be used to clamp length of strapping 14 to scaffolding bracket 16. The strapping may also have a loop at one end or both ends. It will also be appreciated that other forms of attachment member may be employed that have sufficient load rating for supporting scaffolding. Referring to FIG. 7, there is illustrated a karabiner 32, which could be used, as an alternative to pin 20, to attach to loop 18. An extension of the terminus of the scaffolding bracket provides a remote end 50.
In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiments without departing from scope of the Claims. For example, any resilient material of sufficient tensile strength to support scaffolding, including, for example but not limited to climbing rope, or Kevlar™ webbing could be employed. Similarly, the strapping could extend much further along the length of the scaffolding bracket than is shown in the Figures, in other words, not being located proximate the terminus. Additionally, the strapping could be affixed to a remote end.
