Partial-length scaffold planks, having first and second ends and a length less than the space between the scaffold frames, are supported by the transverse support members and occupy the space between the planks other than at the opening. The transverse support member includes spaced-apart plank engagement sections that rest on upwardly facing surfaces of the planks, and a plank end support member that extends between the plank engagement sections. A scaffolding platform system and a method of forming a scaffolding platform are also disclosed.
This application claims priority to U.S. provisional application Ser. No. 61/862,235, filed Aug. 5, 2013, the entire contents of which is incorporated herein by reference.
BACKGROUND OF THE INVENTIONMany scaffold systems commonly include spaced-apart vertically stacked frames that are connected together by spreader bars. The frames commonly define one or more horizontal surfaces that are oriented to support planks or other structures to define a deck or a platform for supporting one or more users at a desired elevated position.

As can be appreciated, the custom fabrication and installation of the filler member such as 18 is time consuming, inefficient and wasteful, in that the filler member 18 commonly has limited applicability to other obstruction configurations. In addition, the overlapping of the filler member 18 on top of the planks 20 results in an undesirable elevation deviation with respect to the work surface associated with the deck or platform. Therefore, there is a need for a scaffolding deck system that can be individualized to form a number of deck configurations as required to accommodate obstructions that must pass through the deck, and which generates a nearly planar platform surface.
SUMMARY OF THE INVENTIONIn accordance with one aspect of the present invention, a scaffolding arrangement comprises a pair of spaced-apart scaffold frames and a scaffold platform supported by the scaffold frames. The scaffold platform is defined by a series of side-by-side planks, and defines at least one opening located between a pair of planks. The opening is formed by the pair of planks in combination with at least one partial-length scaffold plank having first and second ends and a length less than the space between the scaffold frames. The partial-length plank includes a support member located toward the first end that extends between and is supported by the pair of planks at a location between the scaffold frames. In one form, the opening is defined between the first end of the partial-length plank and one of the scaffold frames. In another form, the partial-length plank is one of a pair of partial-length planks, each of which includes a support member, and the opening is formed by the first end of a first one of the partial-length planks in combination with a first end of a second one of the partial-length planks.
Representatively, the support member may include a pair of spaced-apart plank engagement sections interconnected with the partial-length plank. The pair of spaced-apart plank engagement sections may be secured to spaced-apart areas of the partial length plank separately from each other, or alternatively the support member may include a transverse member that extends between and interconnects the plank engagement sections.
Each plank engagement section may include an upper wall configured to engage and rest on an upwardly facing surface of one of the pair of planks when the support member is positioned between the pair of planks. The transverse member may define an open area within which the end of the partial-length plank is received. In one form, the open area defines an axially open passage in the transverse member and the first end of the partial-length plank extends through the passage and outwardly from the transverse member. In another form, the transverse member includes an end wall that at least in part encloses the open area, and the first end of the partial-length plank is positioned adjacent the end wall.
In accordance with another aspect of the invention, a scaffolding platform system adapted to be positioned between a pair of spaced-apart scaffold frames platform system includes a series of full-length planks configured to span the entire distance between the pair of scaffold frames, in combination with a series of partial-length planks, each of which has a length less than the distance between the pair of scaffold frames. Each partial-length plank defines first and second ends, and at least the first end of each partial-length plank includes a support member. When it is desired to form a scaffolding platform without an opening, the full-length planks are employed to fully occupy the area between the scaffold frames to form the scaffolding platform. When it is desired to form a scaffolding platform with an opening, at least one partial-length plank is positioned between a pair of spaced-apart planks that cooperate with the first end of the partial-length plank to form the opening. The support member is engaged with and supported on the pair of spaced-apart planks and the area between the pair of planks and adjacent the first end of the partial-length plank is unoccupied. The partial-length plank is engaged with at least one of the scaffold frames and occupies the space between the pair of spaced-apart planks other than at the opening. A pair of partial-length planks may be engaged with the pair of spaced-apart planks such that an area between the pair of spaced-apart planks and between the first ends of the pair of partial-length planks is unoccupied. The partial-length planks are engaged with the scaffold frames and the pair of spaced-apart planks to occupy the space between the pair of spaced-apart planks other than at the opening. The partial-length planks may have lengths in predetermined increments.
In accordance with yet another aspect of the invention, a method of forming a scaffolding platform between a pair of spaced-apart scaffold frames comprises supporting a series of full-length planks on the pair of scaffold frames such that each full-length plank spans the entire distance between the scaffold frames; providing at least one partial-length plank having a length less than the distance between the pair of scaffold frames, with the partial-length plank having first and second ends and including a support member adjacent the first end; and engaging the support member with a pair of spaced-apart planks at a location spaced from the scaffold frames in a location where it is desired to form an opening in the scaffolding platform. In this manner, the area adjacent the first end of the partial-length plank is unoccupied. The second end of the partial-length plank is supported on one of the scaffold frames, such that the partial-length plank occupies the space between the pair of spaced-apart planks other than at the opening. The method may include the act of providing a pair of partial-length planks, each of which has a length less than the distance between the pair of scaffold frames. Each partial-length plank defines first and second ends and includes a support member adjacent the first end. The act of forming an opening in the scaffold platform is carried out by engaging the support members of the pair of partial-length planks with the pair of spaced-apart planks such that an area adjacent between the first ends of the partial-length planks is unoccupied. The pair of partial-length planks occupy the space between the pair of spaced-apart planks other than at the opening. The pair of partial-length planks may be selected from a plurality of partial-length planks of different lengths, each of which has a length less than the distance between the pair of scaffold frames. As summarized previously, the support member may include a pair of spaced-apart plank engagement sections interconnected with the first end of each partial-length plank separately from each other. Alternatively, the support member may include a pair of spaced-apart plank engagement sections and a transverse member that extends between and interconnects the plank engagement sections.
