A working platform assembly which includes (i) at least two hangar bars (8) capable of being used to support a horizontal platform; and (ii) at least two support brackets (3) for supporting hangar bars which are attached to a building. The brackets and top end of the hangar bars are adapted so as to inter-engage with one another via a twist lock type connection so that the hanger bars can downwardly depend from the bracket when in use.
