Abstract
A system and method for raising a structure, or part thereof, the system comprising vertical jack members connected and disposed about a rail system attached about the periphery of the structure. The vertical jack members comprise an outer sleeve and a slidable inner portion that is driven vertically by a jack screw and drive block. Extensible diagonal cross-braces stabilize the jack members and structure being raised.
Claims10
A method for raising a structure, the method comprising:
- fastening a top rail horizontally along an underside of a plurality of floor joists of the structure;
- coupling a plurality of vertical jack members to the top rail,
- fastening a bottom rail horizontally to an outer tube of each of the plurality of vertical jack member near the ground or floor under the structure;
- coupling at least one of a plurality of cross-braces to the top rail and the bottom rail, the cross brace connected at a first end to the top rail and a second end to the bottom rail, the cross-brace having a retention mechanism configured to allow the cross-brace to extend in a ratcheting manner;
- and
- extending a lower end of the vertical jack member to raise the top rail and structure coupled thereto.
A method for raising a roof structure of a building for installation of a next floor structure and walls for an added story, the method comprising:
- fastening a bottom rail horizontally along a foundation or sill of the building;
- fastening a mid-rail horizontally along an upper structural element of a wall of the building;
- fastening a top rail horizontally along a structural element of a roof of the building;
- coupling at least two vertical wall jack members to the bottom rail, to the mid rail, and the top rail;
- coupling telescoping diagonal cross-braces each at a first end to the mid rail and each at a second end to the top rail, the telescoping diagonal cross-braces having capability to extend but not retract thereby providing lateral support to the existing roof and wall structure during the lifting process where the roof and walls have no structural connection to each other;
- and
- extending an upper end of the vertical wall jack member to raise the top rail and the structural element of the roof coupled thereto.
A method of raising a structure, comprising:
- fastening a first rail horizontally about a first portion of the structure;
- fastening a second rail horizontally about a second portion of the structure, the second portion of the structure disposed below the first portion of the structure and separated therefrom;
- coupling a plurality of jack members between the first rail and the second rail, including:
- coupling a top portion of each vertical jack member to the first rail;
- coupling a lower portion of each vertical jack member to the second rail;
- coupling a pair of cross-braces to the first and second rails, each cross-brace having a first end connected to the first rail and a second end connected to the second rail, each cross-brace extensible and having a locking ratchet mechanism to prevent retraction of the cross-brace;
- and
- extending the lower portion of each vertical jack member to raise the first rail and the attached first portion of the structure.
