ABSTRACT:
This invention relates to a construction wall bracket for use in the erection of residential structures. The construction wall bracket includes a vertical member having a pair of laterally and outwardly-extending stud engagement members which rest against the vertical wall. A horizontal member having an angle bracket extends horizontally outward from the vertical member to support a plank or platform for use by a workman during construction efforts. A support brace is affixed to the vertical member for engagement to the top horizontal stud of a wall. A swing arm having a depending end tab and a pair of longitudinally-extending hinge members is pivotally attached to the support brace about a hinge pin. The upward pivotal rotation of the swing arm with respect to the support brace facilitates the removal of the construction wall bracket during periods of non-use. A safety pin is engaged to the hinge members and against the support brace to prevent pivotal rotation of the swing arm with respect to the support brace during operational positioning and use of the construction wall bracket.
