Abstract

This invention is directed to mechanical staging for use in the construction of a building. Normally, in the construction of a frame building, there is used staging and which staging is made from wood. This invention is directed to the use of mechanical supports for wooden cants and wooden planks. There is a stud gripper. The stud gripper can be placed on studs in a wall and a cant supported on the stud gripper. With two spaced apart walls and having stud grippers for supporting cants it is possible to place planks on the cants. A workman can stand on the planks and be supported for further work in the building. In conjunction with the stud gripper there can be used an adapter bracket. The adapter bracket is supported on the stud gripper. Cants can be supported on the adapter bracket. With spaced apart walls it is possible to have stud grippers and adapter brackets on the studs of the walls and to run cants between the stud grippers and the adapter brackets. Then, support planks can be placed on the cants and workmen can stand on the planks for further work in the frame building. Utility brackets can be supported by the stud gripper. In a wall two spaced apart stud grippers and utility brackets can be supported on the studs. Support planks can be placed on the utility brackets and run along the walls. A workman can stand on the planks and work on the frame building.
