The present invention is an improved, portable structural system which employs braces that are adapted to engage supporting lengths of construction material such as standard 2횞4 studs or standard pipes. The braces have two spaced upper and lower inboard fittings which mount to supporting lengths of construction material. When the upper and lower inboard fittings are clamped to supporting lengths of construction material, horizontal supports of the braces can support a plank or a panel which can be used by a worker as a scaffold, shelf or workbench. The braces may also have outboard fittings for attaching to vertical lengths of construction material for supporting the outboard ends of the braces.

I claim: 1. A portable structural system for supporting horizontal surfaces, comprising: at least two braces, each of the at least two braces having an inboard end and an outboard end, a horizontal support extending from the inboard end to the outboard end for supporting a working surface, upper and lower inboard fittings fixed to the inboard end of each of the at least two braces, each upper and lower inboard fitting including a channel shaped body including first and second parallel flanges spaced to receive a standard, upright wood stud, and at least each upper inboard fitting further including: (a) cleats projecting from the first flange of the channel shaped body for penetrating the wood stud, (b) a threaded bolt and threaded insert arrangement mounted to the second flange of the channel shaped body whereby when the threaded bolt is tightened into the stud, the first flange and the cleats are clamped against the surface of the wood stud as the cleats penetrates the surface of the wood stud, whereby at least each upper inboard fitting may grip the standard upright wood stud. 2. The portable structural system of claim 1 wherein, the upper and lower inboard fittings are releasably secured to the inboard end of each of the at least two braces such that the upper and lower inboard fittings can be interchangeably removed and replaced by a second set of upper and lower inboard fittings having flat plates with fastener holes for mounting to a flat wall surface, whereby the portable structural system may be quickly and easily configured to be mounted to an open frame structure including vertical studs or configured to be mounted to a flat wall. 3. The portable structural system of claim 1 wherein, at least one of the braces also has an outboard fitting for releasably mounting to an upright length of material for supporting the outboard end of the at least one brace. 4. The portable structural system of claim 1 wherein, at least one of the braces also has an outboard fitting for releasably mounting to an upright length of material for supporting the outboard end of the at least one brace, and, wherein, at least one of the upper inboard fitting and the lower inboard fitting includes an opening for receiving a fastener for installing a fastener for further securing the fitting to the standard wood stud. 5. A portable structural system for supporting horizontal surfaces, comprising: (a) at least two braces, each of the at least two braces having an inboard end and an outboard end, a horizontal support extending from the inboard end to the outboard end for supporting a working surface, upper and lower inboard fittings fixed to the inboard end of each of the at least two braces, each upper and lower inboard fitting including a channel shaped body including first and second parallel flanges spaced to receive a standard, upright wood stud, and at least each upper inboard fitting further including: (i) cleats projecting from the first parallel flange of the channel shaped body for penetrating the wood stud, (ii) a bolt and threaded insert arrangement mounted to the second parallel flange whereby when the bolt is tightened into the stud, the first flange and the cleats projecting from the first flange are clamped against the surface of the wood stud and penetrate the surface of the stud, so that each fitting may grip the standard upright wood stud, (b) each of the at least two braces also having an outboard fitting for releasably mounting to an upright length of material for supporting the outboard end of each of the at least two braces, and, (c) rail fittings that can be releasably secured to the upright length of material for supporting rails mounted to more than one upright length of material supporting the outboard ends of more than one brace. 6. The portable structural system of claim 5 wherein, at least one of the upper inboard fitting and the lower inboard fitting includes an opening for receiving a fastener for installing a fastener for further securing the fitting to the standard wood stud. 7. The portable structural system of claim 5 further comprising, a base fitting that is releasably securable to the lower end of the length of material for supporting the outboard end of a brace. 8. The portable structural system of claim 5, further comprising, (a) an opening in at least one of the upper inboard fitting and the lower inboard fitting for receiving a fastener for installing a fastener for further securing the fitting to the standard wood stud, and, (b) a base fitting that is releasably securable to the lower end of the length of material for supporting the outboard end of a brace. 9. The portable structural system of claim 5 wherein, the upper and lower inboard fittings are releasably secured to the inboard end of each of the at least two braces such that the upper and lower inboard fittings can be interchangeably removed and replaced by a second set of upper and lower inboard fittings having flat plates with fastener holes for mounting to a flat wall surface, whereby the portable structural system may be quickly and easily configured to be mounted to an open frame structure including vertical studs or configured to be mounted to a flat wall.
