Abstract

This invention consists of a multi-sectioned, pre-cast support for mobile homes and similar structures, incorporating leveling and hold-down devices to facilitate and improve the finished installation.

Claims

1. A support for a mobile home or similar structure having a structural frame at its underside, comprising:

a base disposed and held within a post hole bored in the ground and adapted to underlie said structural frame, said base being of two-part formation, including a lower pad resting on the ground surface defining the bottom of the bored hole, and an upper hollow member resting on said pad and having an outer wall extending upwardly from said pad to a smaller transverse dimension, said upper hollow member having a transverse wall at its upper end providing a support surface on its outer side, a concrete collar around the periphery of said pad and said outer wall to hold said base in position within said bored hole, a cap member having its lower end seated on said support surface, said cap member extending upwardly therefrom, a jack screw slidably carried by said cap member for upright axial movement, an upper portion of said jack screw extending upwardly beyond the upper end of said cap member and carrying a retaining pad upon which said structural frame rests, a leveling nut threaded on said jack screw upper portion and bearing against said cap member upper end, and a rod having its upper end threaded into the lower portion of said jack screw, said rod extending through an opening in said transverse wall of said upper hollow member and having an abutment within said hollow member, said abutment being adapted to bear against the inner side of said transverse wall to limit upward movement of said jack screw.

2. The construction according to claim 1, wherein the outer wall of said upper hollow member is conical, tapering from a larger diameter at said pad to a smaller diameter at the top of said hollow member, the combined height of said pad and said hollow member being such relative to the depth of the bored hole so that the top of said hollow member, which forms said transverse wall, is substantially flush with the ground level surrounding said hole, said concrete collar extending around the periphery of said pad and the lower portion of said conical wall, said hollow member being locked in place by earth tamped therearound and filling said hole.

3. A support for a mobile home or similar structure having a structural frame at is underside, comprising:

a base connected to the ground and adapted to underlie said structural frame, said base being hollow at its upper end and having a transverse wall thereat providing a support surface on its outer side, a cap member having its lower end seated on said support surface, said cap member extending upwardly therefrom, a jack screw slidably carried by said cap member for upright axial movement, an upper portion of said jack screw extending upwardly beyond the upper end of said cap member and carrying a retaining pad upon which said structural frame rests, a leveling nut threaded on said jack screw upper portion and bearing against said cap member upper end, and a rod having its upper end threaded into the lower portion of said jack screw, said rod extending through an opening in said base transverse wall and having an adjusting nut threaded thereon and disposed within the hollow of said base, said nut being adapted to bear against the inner side of said base transverse wall to limit upward movement of said jack screw, aNd said base having an opening in its side wall to provide access to its hollow interior and said adjusting nut.
