Description

BACKGROUND OF THE INVENTION

1. Field of Invention
The present invention relates to the field of scaffolding used in building construction. More specifically, the present invention relates to a bracketed scaffolding system used to secure a scaffold to a wall before the wall is erected.
2. Description of Related Art
Scaffolding has traditionally been used in building construction projects to provide raised platforms or ramps that are used for pedestrian movement as well as the passage of building materials or to support structures such as the roof during construction. Scaffolding has traditionally consisted of tube and coupler designs wherein the uprights, or posts, rise from the ground or some other source of solid support. However, there are building scenarios where the scaffold may be difficult to level and stabilize due to lack of solid support. As a result, scaffold designs have been modified to hang from a portion of the structure rather than rely on ground support.
There are many structure-supported scaffold designs in the prior art. Most attach temporarily to the roof while others are attached to a wall using permanent anchors to secure to the completed wall structure. However, there still exists a need for a wall supported scaffold design that can be secured to the wall before the wall is erected and can be detached from the wall after use, such that permanent anchors are not required.

SUMMARY OF THE INVENTION

It is the object of the present invention to address several challenges in previous attempts to design a wall supported scaffolding system. The bracketed scaffold system of the present invention is configured for attachment to the wall prior to the wall construction. The scaffold bracket generally uses a hook adapter to hang the scaffold bracket over the top of the wall and a securing plate that is secured to the stud inside the wall to secure the scaffold to the wall. The hook adapter is attachably connected to the upper end of a vertical wall bar and the securing plate is longitudinally parallel with and attachably connected to the lower end of the vertical wall bar. A horizontal rail is perpendicular to the vertical wall. A connecting brace is attachably connected to the lower end of the vertical wall bar and the distal end of the horizontal rail, thereby forming a triangular configuration. The vertical wall bar is braced against the surface of the wall using a horizontal brace.
Other aspects and features of the present invention will become apparent to those ordinarily skilled in the art upon review of the following description of specific embodiments of the invention in conjunction with the accompanying figures.
