ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to structural support for the periphery of a manufactured home, mobile home or trailer coach, and more specifically to a slanted push/pull connector between a main beam and an outer end of a floor joist.
2. Description of the Related Art
A manufactured home typically includes one or more longitudinal main beams which support a plurality of transverse floor joists which directly support the floor and the wall structure including wall studs. The main beams are typically I-beams, but may be C-beams or have another configuration.
Often it is desirable to further support the outer ends of floor joists, for example to even the floor, to compensate for large local loads, or to compensate for adjacent large wall openings.
Occasionally the outer end of a joist is too high such that the floor is not level or the floor does not align across a mating seam.
Therefore, there has been a need for means both for supporting, i.e. pushing up, and for pulling down on the periphery of a manufactured home.
SUMMARY OF THE INVENTION
A push/pull outrigger for a manufactured home spans between the lower end of the main beam and the outer end of a transverse floor joist and selectively provides a push or pull force to the outer end of the floor joist to raise or lower the level of the floor. The outrigger generally comprises and an elongate portion of adjustable length for spanning between the lower end of the beam and the outer end of the joist, a bracket attached to the lower end of the beam, and a nut fastening the elongate portion to the bracket.
The elongate portion has a longitudinal axis and comprises a fixed portion and a movable portion. The fixed portion includes an upper end attached to the outer end of the joist such that the outrigger can exert an inward or outward longitudinal force on the joist and a lower end having a threaded bore. The movable portion is a threaded shaft having a lower end adapted for bearing against the beam and an upper end attached to the threaded bore of the fixed portion for adjusting the length of the elongate portion and exerting an outward force on joist outer end.
A bracket attached to the lower end of the beam includes a bore through which the lower end of the threaded shaft is freely disposed. A nut is attached to the threaded shaft between the bracket bore and the beam. Tightening the nut against the bracket while preventing the shaft from turning relative to the nut exerts an inward force on the joist outer end.
Other features and many attendant advantages of the invention will become more apparent upon a reading of the following detailed description together with the drawings in which like reference numerals refer to like parts throughout.
