DETAILED DESCRIPTION OF THE INVENTION

Referring to figures 1, 2 and 3 one example of a modular scaffolding frame assembly of the present invention comprises modular scaffolding frame 10. The scaffolding frame 10 generally comprises a main support member, which in this particular example comprises main support 12, a main support load distributor or load distribution member in the form of main support load distributor 14 and a platform support member in the form of support arm 16. The main support load distributor 14 and support arm 16 are shown in more detail in respective figures 9 - 11 and 12 -15. The modular scaffolding frame further comprises platform rail supports which in this particular example comprise rail support 20, platform rail posts in the form of rail posts 22, and platform rails 24, The support arm supports platform 30.

Referring to figures 6, 7 and 8 the main support 12 comprises a main support attachment portion in the form of attachment bracket 32. The attachment bracket 32 is designed to hook over a top plate 35 of building frame 38 (see figures 2 and 3). An elongate portion of the main support in the form of a tube 34 extends downwardly away from the attachment bracket 32 when " the main support 12 is appropriately attached to the top plate 35. Referring also to figure 1 and 12 - 15, the support arm 16 attaches to the main support 12 via the tube 34. The support arm 16 comprises tube 36 having a cross section corresponding to that of the tube 34 and is thereby designed to slideably receive that tube. The support arm 16 is located relative to the main support 12 by bolts which threadably engage the support arm 16 and engage the tube 34 via threaded holes of the tube 36.

As can been seen from figures 1-3 and 6-8, when platform 30 is supported by the support arm 16, a downward force is applied to the support arm. The support arm 16 in turn applies a rotational force to the main support 12 via the tube 34 and about the attachment bracket 32. This forces the tube 34 of the main support 12 toward the building frame 38. This force applied to the tube 34 is spread over at least two wall studs 39 (see figure 2) by a load distributor rail which in this preferred embodiment is load distributor bar 40 ( best seen in figures 1 and 2). As will be readily appreciated by persons skilled in the relevant art, the load distributor rail could alternatively, for example, comprise a load distributor strap or shaft. The.Load distributor bar 40 slidably engages the remainder of the main support load distributor 14. The main support load distributor 14 is slidably attached to the main support 12 via tube 56 of the main support load distributor 14 (best seen in figures 1 and 9). The main support load distributor 14 is located and secured relative to the main support 12 in a similar manner to that described in relation to the support arm 14 and main support 12. The slidable nature of the load distributor bar 40 enables its position relative to the tube 34 of the main support 12 to be adjusted to appropriately contact wall studs 42 of the building frame 38. This feature, in combination with the length of the load distributor bar 40, ensures the bar 40 can be positioned to contact at least three wall studs 39 regardless of the position along the top plate where the attachment bracket 32 is attached. In this way the rotational force applied to the main support 12 can be spread over three wall studs. The load distributor bar 40 is located and secured relative to the main support load distributor 14 in a similar manner to that described in relation to the support arm 14 and main support 12. A threaded hole 41 designed to receive a locating bolt (not shown) is shown in figures 10 and 11.

Referring again to figures 1-3 and 6-8, the rail supports 20 are designed for detachable attachment to the support arm 16. An alternative platform support member comprises a support arm (notshown) having a rail support which is integrally formed with the support arm.

Referring to figures 15-17 the rail supports 20 comprise a channel 42 which is designed to fit over a tube 44 of the support arm 16. The rail supports 20 also include a tube 46 which extends transversely of the channel 42. The channel 42 enables the position of the rail supports 20 to the adjusted relative to the tube 44. This adjustment in turn enables the position of the rails 24 to be adjusted. The rail supports 20 are secured to the support arm 16 in a similar manner to that which the support arm 14 is secured to the main support 12.

Figures 4 and 5 represent another example of the modular scaffolding frame assembly 10, in the form of modular scaffolding frame assembly 48. This other example involves assembly of the frame so that the main support is positioned inside building frame 38. A main support 50 of the modular scaffolding frame assembly 48 is orientated 180 degrees relative to the main support 12 of the modular scaffolding frame assembly 10. A main support load distributor 52 is also orientated 180 degrees relative to its orientation in figures 1-3 so that tube 54 rather than tube 56 slideably receives the main support tube 34 (see also figures 1 and 9 - 11). In this way a strap holder 58 (best seen in figures 1 and 9) of the main support load distributor 52 is positioned so that the load distributor strap 40 still contacts outer surfaces of the wall studs 42.

The modular scaffolding frame assembly 10 is designed for fitting to building frame 38 from outside the frame. However, the modular scaffolding frame assembly 48 is designed as shown in Figures 4 and 5, to be fitted to building frame 38 from inside. In some situations it is difficult to attach the modular scaffolding frame assembly to a building frame from outside the frame. It may, for example, be difficult if the terrain surrounding the building frame is unlevel or drops sharply away. It is also difficult if the scaffolding relates to a second storey or higher of a multistorey building. The modular scaffolding frame assembly 48 therefore facilitates scaffolding erection in these types of situations by enabling it to be erected from an internal floor of the building to which the scaffolding is to be attached.

Referring to figures 1 to 5 and 50 to 53 it can be seen that scaffolding frame assemblies 10 and 48 also include planks 70 and plank joiners in the form plank sleeves 72. It can be seen from these figures that the plank sleeves 72 have deck edge locators in the form of separator tags 74 and an inspection hole in the form of hole 76. The plank sleeves enable planks to be securely joined as is readily evident from the figures to a person skilled in the relevant art.

Scaffolding frame assemblies 10 and 48 also include kick boards 80 (see figures 1 to 5 and 33 and 34). Referring to figures 30 to 32 and 35 to 45, the kick boards 80 are joined by a kick board joiner and another kick board joiner in the form of slide chassis 84 and corner slide 86 respectively. The slide chassis 84 comprises bands in the form of straps 88. The corner slide 86 comprises opposed hooks and tubes in the form of strap 90 and square sectioned tubes 92. It will be readily apparent from the figures to a person skilled in the relevant art how the kick boards are assembled.

Referring to figures 26 to 29 and 46 to 49, scaffolding frame assemblies 10 and 48 can also include a corner sleeve 100 and corresponding support post (not shown). One example of a corner sleeve 100 is visible in figures 3a and 3b and slidably receives a plank 70 and support post in a manner that will be readily apparent to a person skilled in the relevant art.lt will be appreciated by a person skilled in the relevant art that the invention in at least its preferred form has at least the following advantages:

1. A main support of the modular scaffolding frame assembly of the present invention can be attached to a top plate of a building frame from either inside or outside the building frame

2. The modular scaffolding frame assembly comprises a main support load distributor or load distribution member which transfers load supported by the main support to two or more wall studs of the building frame

3. The modular scaffolding frame comprises an adjustable rail support for adjustment of rails which are positioned above a platform of the modular scaffolding frame assembly so that they are positioned either closer to or further away from a wall frame which the modular scaffolding frame assembly is mounted to

4. A support arm of the modular scaffolding frame is designed for detachment from a main support of the modular scaffolding frame assembly facilitating attachment of the frame assembly to a building frame

5. The main support load distributor is also detachable from the main support to further facilitate attachment of the frame assembly to a building frame

6. The support arm is adjustable along the length of the main support tube to enhance platform support adjustability

7. Plank joiners that enable planks, for example those of a scaffolding frame, to be readily and securely joined

8. Kick board joiners that enable kick boards, for example those of a scaffolding frame, to be readily and securely joined.

It will appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in specific embodiments without departing from the spirit or scope of the invention broadly described. For example, different members of a preferred embodiment of the modular scaffolding frame assembly such as the main support and support arm could be foldably connected. This foldable connection should also enable the support arm to be unfolded to a platform support position. It would also preferably allow the main support to be alternately orientated relative to the support arm for attachment of the main support to a top plate of a building frame either from inside or outside the building frame. Other alternative embodiments include, for example, different shaped support arms. They could also comprise members similar to those of preferred embodiments of the modular scaffolding frame assembly but, for example, with tubes of different shaped cross sections or, where appropriate, equivalent solid components. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
