BACKGROUND
1. Field
The disclosed embodiments relate to a frame construction method and apparatus and, more particularly, to a frame construction method and apparatus adapted to produce framed structures.
2. Brief Description of Earlier Developments
Home or commercial construction projects often involve framing carpentry. Typical construction involves a dimensioned plan and a specification reflecting the desired construction provided to carpenters or a framing crew. The amount of dimensioned lumber is determined, ordered and delivered to the construction site. Although some of the lumber may be provided cut to length, for example, wall studs, much of the lumber needs to be cut to length from larger pieces of the dimensioned lumber. Cutting the lumber to the desired size may be performed using tape measures, squares, or otherwise used in combination with chop saws or circular saws. Alternately, templates are made to facilitate quick marking and cutting. In parallel or after the lumber has been cut to size, framers manually mark the location of the framed construction and manually assemble the structure, typically starting with the sills, floor joists and floor, walls, ceiling and roof in the case of a simple one story home. The process tends to be time consuming and costly as much of the cutting, measurement, marking, locating and fastening is manual, time consuming and labor intensive and is subject to inaccuracies due to communication errors and the quality of the carpenters and framing crew. Accordingly, there is a desire to reduce the time, cost and inaccuracies associated with manual home structure framing and sheathing.

Referring now to FIG. 15, there is shown a isometric view of pin setter 84. Referring also to FIG. 16, there is shown a top view of pin setter 84. Referring also to FIG. 17, there is shown an end view of pin setter 84. Referring also to FIG. 18, there is shown a side view of pin setter 84. Referring also to FIG. 19, there is shown an exploded isometric view of pin setter 84. Pin setter 84 fires pins accurately into end 400 of stud 400 or wood component 402 to enable fast on-site, or within factory alignment and assembly of wall panels or assemblies where pins are located to mate with mating features, for example, bores or holes made by stick machine 80 (FIG. 1). Interior (or exterior) wall components may be cut, ends labeled and ends quickly pinned with pin setter 84. Pin-setter 84 may either be affixed to Stick Machine 80, or be used as a stand-alone device. For example, plates may be drilled at pinning locations on Stick Machine 80. Compact sets of boards (vs panelized wall with large volume of air to transport) may be efficiently transported to site, carried to the place of installation, laid out, marks (e.g. letters or numbers) matched, boards tapped together using pins, and the wall nailed after assembly and tilted into place. This method may be particularly suitable for interior walls or home improvement projects where transport or handling of a finished wall is difficult. Pin setter 84 may also be used to set pins in the ends of rafters or joists to improve the speed and accuracy of installation, for example, to ridge beams or rim joists as previously shown. Pin setter 84 may be a pin setting apparatus 84 adapted to place pin 404 in wood component 402. Pin setter 84 is shown having frame 410, pin insertion portion 414 coupled to frame 410, pin insertion portion 414 adapted to insert pin 404 into wood component 402. Guide portion 420 is coupled to frame 410, guide portion 420 adapted to guide the wood component 402 toward the pin insertion portion 414. Stop portion 426 is coupled to frame 410 with stop portion 426 adapted to stop surface 430 of wood component 402. Pin 404 is inserted into the surface 430 of wood 402 such that pin 404 extends from surface 430 of wood 402 at a fixed length 434. In the embodiment shown, guide portion 420 has first and second guide surfaces 440, 442 where guide surfaces 440, 442 have tapered inlets to provide for easy insertion. Rollers 444, 446, 448, 450 cooperate with surfaces 440, 442 to ensure pin 404 is inserted consistently with respect to the sides of board 402. Insertion portion 414 may be a pneumatic nailer where the nose 460 of nailer 414 protrudes beyond stop surface 426 preventing misfires. In practice, board 402 depresses nose 460 until the end 430 engages stop 426 allowing nailer 414 to insert pin 404 in a consistent manner.
