ABSTRACT:
A height-adjustable load bearing support for attachment to a mobile home frame beam for supporting the home for occupancy has a bottom adjustment screw and is much better able to withstand lateral load forces, such as resulting from an earthquake. The support includes a stand, a vertical support shaft, and a bottom adjustment screw. The stand includes a base and legs which project upward to support a collar. A vertical shaft is supported by and within the collar and is slidable vertically. The vertical support member includes a side surface for bearing against the collar and an upper end disposed above the collar top end that includes a load support plate for supporting a frame beam. The load support plate includes tabs for attaching the plate to a beam such that the beam cannot slide off. The height of the vertical shaft is adjusted relative to the base by a screw connected to the lower end of the vertical shaft. Thus, compressive forces from vertical loads applied to the vertical shaft are transmitted to the base thru the adjustment screw, and shear and moment forces caused by lateral loads applied to the vertical shaft are transmitted to the base thru the collar and legs.
