Abstract
An interconnected scaffolding platform having at least two elongated staging sections which are butted together so as to lie colinearly and in a common plane. A pair of lateral plates longitudinally project from the confronting ends of each of the sections. The plates are staggered with respect to each other to permit interfitting of the plates. A transverse bore is formed through all of the plates to define a passageway. A U-shaped bar arrangement interfits through the passageway and has depending arms which can secure the interconnected staging sections to a support member.
Claims8
An interconnected scaffolding platform, comprising:
- at least two elongated staging sections to be butted together;
- a pair of end portions longitudinally projecting from the confronting ends of each section, each pair being staggered with respect to the other pair, so as to permit a mating interfit of the two pairs of end portions;
- each of said end portions having a transverse bore therethrough, said bores being aligned in the interfit position of the end portions so as to define a passageway transverse to the sections, and
- coupling means for extending through said passageway to securely interconnect said sections together, whereby the interconnected sections will lie colinearly in a common plane, said coupling means comprising an inverted U-shaped bar arrangement having one portion defining a bight portion extending through said passageway and other portions defining depending arms to retain the bar arrangement positioned through said passageway, wherein said interconnected platform rests on a support member having a vertical receiving slot therein for receiving said depending arms, and comprising locking means at the distal ends of said depending arms for preventing removal of said arms from said receiving slot.
