ABSTRACT:
Improved scaffolding designed to include an integrated walk board and an integrated work board disposed above the walk board. The improved scaffolding of the present invention includes primarily a pair of end frames, a walk board, a work board, and handrail. Each end frame is configured to be common to successive scaffolding sections and includes a center post, a forward post, and a rearward post. A walk board support is mounted between the center and forward posts and work board support is mounted between the center and rearward posts at an elevation above the walk board support. Each of the walk board and work board supports is provided with a central support member on either side of which is defined a plurality of receptors configured to receive mounting studs carried by the walk board and the work board. The lower end of each post defines a receptor configured to closely receive a stud carried by the upper end of corresponding posts of a further end frame. Electrical outlets are provided at each end of the center post for powering electrical equipment. Wiring is disposed within the center post, with an outlet disposed at each end of the center post. A jumper is provided for establishing electrical communication between successive pairs of end frames. An end handrail is secured between the upper ends of the forward and center posts. A ladder is provided for ascending or descending the scaffolding. Handrail is provided on the forward and rearward sides of the scaffolding. In order to establish continuous scaffolding around corners of structures, a corner walk board and a corner work board are provided.
