Aluminum roof scaffolding plank

Abstract

A roof scaffolding system comprising an aluminum roof scaffolding plank constructed from high strength aluminum having a unique C-shaped design with molded features that imparts, stability and weight bearing strength to the plank when it is mounted on roof scaffolding brackets. The plank has ridges on its top surface to provide a non-slip surface and a plurality of holes along the sides at the top and the bottom to enable a lock pin to be inserted through them and through a roof bracket hole to secure the plank to the roof bracket. The use of the lock pin to secure the plank to the roof bracket in place of nails, allows for securing and releasing the plank from the roof bracket with one hand instead of requiring the use of two hands when nails are used to secure the scaffolding plank to the roof bracket.

What is claimed is: 
     
         1 . A roof scaffolding system comprising:
 a roof scaffolding plank structure constructed from aluminum;   said roof scaffolding plank structure having a C-shaped design;   said roof scaffolding plank structure having a plurality of ridges on a top surface;   said roof scaffolding plank structure having a plurality of holes on a first side and a second side of said top surface with said plurality of ridges; and   said roof scaffolding plank structure having a plurality of holes on a first side and a second side at a bottom of said roof scaffolding plank structure.   
     
     
         2 . The roof scaffolding plank structure as in  claim 1  wherein said plurality of ridges on the top surface of the plank structure provide a non-slip surface. 
     
     
         3 . The roof scaffolding plank structure as in  claim 1  wherein the top surface of the plank structure has a rubberized coating to provide a non-slip surface. 
     
     
         4 . The rood scaffolding plank structure as in  claim 1  wherein the C-shaped design has molded features to provide superior strength to the plank structure. 
     
     
         5 . The roof scaffolding plank structure as in  claim 1  wherein the roof scaffolding plank structure is secured to a standard roof bracket by means of a lock pin that is inserted through said plurality of holes in said plank structure and through a hole in the roof bracket that is attached to a roof structure. 
     
     
         6 . The roof scaffolding plank structure of  claim 1  wherein the use of the lock pin to secure the plank structure to the roof bracket requires the use of only one hand for securing and removing the plank from the roof bracket as compared to the use of two hands for installing and removing a wood scaffold board plank from a roof bracket. 
     
     
         7 . The roof scaffolding plank of  claim 1  wherein the plank is constructed from aluminum extrusion 6061 or aluminum of equal strength. 
     
     
         8 . The roof scaffolding plank of  claim 1  wherein the plank is constructed in sizes to fit standard roofing brackets routinely used in steep slope roofing installations.
