CONSTRUCTING LUMBER STRUCTURES
FIELD OF THE INVENTION
A grooved construction lumber element is described for constructing lumber structures such as portions of a house frame, building walls, guard rails for decking or verandas and the like structures wherein lumber pieces are 1o secured at repeat spaced intervals.
BACKGROUND OF. THE INVENTION
In the construction of lumber structures, such as wood building structures, it is necessary to erect walls, is flooring, roofing wherein load bearing elements such as joists, studs, trusses, are secured at substantially equidistantly spaced intervals. When constructing a wall with wood framing studs it is necessary to secure the studs to a top surface of a lower plate at spaced intervals.
20 These spaced intervals are usually measured using a measuring tape and a pencil mark is made on the plate at the repeat intervals. These measurements are not always accurate and subject to human errors as the construction worker must remember ascending numbers of a predetermined 25 spaced intervals and often makes a human error. and a stud may be secured at the wrong position and this is detected later on when it is time to cover the framing with covering sheet material of predetermined size.
Another disadvantage in the construction of 30 building structures wherein lumber elements must be spaced at regular intervals is that the butt end of the studs are usually secured on a side surface of a bottom or top plate member by nails. Because often construction lumber is not totally dry the studs will warp longitudinally as they 35 slowly dry and this results in an irregular wall surface.
A still further disadvantage in the construction of building structures wherein lumber elements must be secured at regular spaced intervals is that such construction requires skill labor and it can be said to be time-consuming due to the fact that many measurements need to be taken not to make errors and when errors occur it is time-consuming to rectify them. It is also time-consuming to groove lumber pieces to interconnect butt ends of studs in a base plate. It is also time-consuming to construct guard railings where rail posts need to be secured at regular spaced intervals without error. For these reasons, l0 it is costly to construct these types of structures.
