Description:

BACKGROUND OF THE INVENTION

In a principal aspect the present invention relates to a speed jig for wall and rafter construction that will ease and speed up the construction process for wall framing and rafter centering on a common 16 inch or 24 inch on center norm which has been established as the most common building practice in th current building standards.

Modern building requirements have long been in need of a device to accurately aid in speed construction of wall panels and rafter spacing, and must be a light weight and durable device that can stand up to the harsh building environment.

Consequently this wall, rafter layout speed jig was designed to aid all builders from the novice to the professional builder to provide a quick means of centering the wall stud construction and the roof rafter center to center location in a simple efficient way.

SUMMARY OF THE INVENTION

Briefly the present invention relates to wall stud and rafter building construction to allow and keep each wall stud or rafter to continue on a said center to center dimension of either 16 inch or 24 inch on center which is considered the norm in todays building standards.

There are two parts to this invention which are separable, the main wall stud centering device and the detachable predetermined length arm, which can be separated by the removal of one bolt and wing nut. The main device has a saddle which slides over the wall stud and has an arrow built into the bottom center of the saddle to align the wall stud to a premarked wall plate, the saddle has flat shoes on either side at a 90 degree angle to allow the wall stud and wall plate to be constructed square. Using the main device alone on a premarked plate will allow for quick centering of the wall stud to the wall plate. By attaching the predetermined length arm with the attaching bolt and wing nut a continued on center dimension can be maintained of either 16 inch or 24 inch during wall framing which will provide quick and accurate construction. The predetermined length arm can be quickly adjusted from the 16 inch to the 24 inch on center position by the removal of a bolt and wing nut and swiveling the outside part of the predetermined arm and reinstalling the bolt and retaining it with the wing nut.

It is the object of this invention to provide a rugged, lightweight, dependable way of speeding wall stud and rafter centering with accuracy, and to allow a quick change from the 16 inch to the 24 inch on center adjustment. It is also the intention of this invention to be low cost to be affordable to all novice or professionals.

The invention can be comprised of rugged plastic, aluminum, or steel during the manufacturing process. All advantages and features are further explained in the detailed description which follows.
