Abstract

A plurality of spaced, rigid rectangular frames that are vertically adjustable are employed to support manufactured buildings. The frames are formed of pedestals interconnected by vertical trusses. The upper ends of the frames, above the support pedestals are clamped to the flanges of I-beams of the building chassis so as to prevent the building from shifting relative to the foundation.

Claims

1. A building foundation system comprising a pair of spaced, vertically extending pedestals and a truss extending between said pedestals wherein said pedestals and said truss from a vertically oriented rigid frame, said pedestal including an upper portion to which said truss is attached, a base, and a vertically adjustable connection between said base and said upper portion that enables each pedestal to be precisely adjusted vertically so that the upper ends of the pedestal are dead level and yet the pedestals accommodate variations in elevation of the surfaces on which the bases rest, said truss comprises a pair of parallel, transversely extending, vertically spaced members rigidly attached to said pedestal upper portions, and braces extending diagonally between and rigidly connected to said members, a generally U-shaped channel on the top of each of said pedestal upper portions with the open end of the channel facing upwardly, and with the upper one of said truss members being positioned between the legs of the channel, and a bolt extending through the channel and said upper member.

2. The system of claim 1, wherein said channel includes a pair of wings formed integral with the upper ends of the channel legs and extending transversely outwardly from the upper ends of the legs, each of said wings having a flat upper surface, and clamps being adapted to clamp said wings to a building.

3. The system of claim 1, including an elongated brace having a lower end secured to said pedestal upper portion at a location spaced downwardly from the upper end of said pedestal, said elongated brace extending diagonally, upwardly away from said pedestal with the upper end of the elongated brace being spaced from the pedestal at the height of the pedestal, said elongated brace including a flat plate on its upper end adapted to receive clamps for securing the upper end of the elongated brace to outwardly extending flanges on the lower end of a beam.

4. The system of claim 3, wherein said plate is rigidly secured to the upper end of said brace at a precise angle so that said plate is horizontal when in use with the lower end of the brace secured to said pedestal portion at said location.

5. The system of claim 4, wherein said lower end of said brace is pivotally secured to said pedestal to enable the upper end of the brace to be swung upwardly into position with said plate being automatically placed in flush bearing alignment with a beam.

6. A building foundation system comprising a pair of spaced, vertically extending pedestals and a truss extending between said pedestals wherein said pedestals and said truss form a vertically oriented rigid frame, said pedestal including an upper portion to which said truss is attached, a base, and a vertically adjustable connection between said base and said upper portion that enables each pedestal to be precisely adjusted vertically so that the upper ends of the pedestal are dead level and yet the pedestals accommodate variations in elevation of the surfaces on which the bases rest, said pedestal includes a channel having a generally U-shaped cross section with a closed end extending horizontally and fixed to the upper end of said pedestal, a pair of vertically extending legs forming an open upper end, and a an upper transverse member of said truss being positioned within said channel and adapted to be attached thereto by a bolt extending through the legs of the channel and said upper member.

7. The system of claim 6, including a pair of vertically extending plates attached to said pedestal and spaced to receive an end of a lower member of said truss.

8. The system of claim 7 including a second truss extending perpendicular to the first mentioned truss and attached to one of said pedestals, said one pedestal having a pair of holes thereon for receiving a bolt to be threaded into the end of upper and lower members of said second truss.

9. A building support system comprising a generally rectangular frame including at least four spaced vertically extending pedestals, and a truss extending between each adjacent pair of pedestals, each of said trusses includes a pair of vertically spaced, horizontally extending members, and a plurality of braces extending diagonally between each of pair of horizontally members, and clamps secured to the top of said pedestal for attachment to flanges of beams extending beneath the building, said pedestal includes on its upper end a generally U-shaped channel opening upwardly with a pair of upwardly extending legs defining a spaced for receiving the upper one of said pair of truss members, and a bolt extending through said channel legs and said upper truss member to rigidly secure said upper truss member to said channel.

10. A foundation system for a manufactured building comprising a vertically extending pedestal having a channel rigidly secured to its upper end, with the channel having a pair of upwardly extending parallel legs opening upwardly to define a space between the legs, a first vertically extending truss including a lower horizontal member attached to said pedestal and an upper horizontal member having an end portion positioned within said channel, a second vertically extending truss being perpendicular with respect to said first truss and having a lower horizontal member secured to said pedestal and having an upper horizontal member, the end of the upper horizontal member of said second truss having an end surface for engaging the exterior side of one of said channel legs, and a bolt extending through said channel legs and through the upper horizontal member of said first truss to precisely position that upper member, said bolt being threaded into the end of the upper horizontal member of said second truss to thereby secure that member to said pedestal.

11. The system of claim 10, including a pair of clevis plates extending outwardly from the lower portion of said pedestal with the plates being spaced to receive one end of the lower member of said first truss, and a bolt extending through said plates and the lower member of said first truss to precisely secure the lower member of said first truss to said pedestal, and a bolt extending through said lower portion of said pedestal and being threaded into the end of the lower horizontal member of said second truss to thereby secure the lower member of said second truss to said pedestal.

12. The system of claim 10, wherein said channel includes a pair of wings extending horizontally outwardly from the upper end of the legs of said channel for engaging the lower surface of a beam extending beneath said building, and clamps secured to said wings for cooperating with flanges on the end of said beam to secure the beam to the pedestal.
