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.
Claims17
A jacking system for raising a structure, the jacking system comprising:
- a bottom rail disposed about a periphery of the structure;
- a top rail disposed about a periphery of the structure, the top rail separated from the bottom rail by a distance;
- and
- at least one of a vertical jack member disposed between the bottom rail and the top rail, the vertical jack member including an outer support sleeve and an inner portion slidable within the outer support sleeve, the vertical jack member having a threaded rod disposed within the vertical jack member, the threaded rod coupled to at least one of a slidable inner portion, and configured to vary a length of the vertical jack member, thereby causing the distance between the bottom rail and the top rail to vary.
A jacking system comprising a rotating, self-locking threaded lifting rod configured to move a first drive block, the first drive block configured to engage a first lifting element, the first lifting element configured to be restrained at a first extended length, the rotating self-locking threaded lifting rod further configured to engage with a second drive block, the second drive block configured to engage a second lifting element, the second lifting element configured to further extend the first lifting element to a second extended length.
A jacking system for raising a roof structure of a building for installation of a next floor structure and walls for an added story, the jacking system comprising:
- a bottom rail for fastening horizontally along a foundation of the building;
- a mid-rail for fastening horizontally along an upper structural element of a wall of the building;
- a vertical wall jack member including a bottom coupling to the bottom rail, a mid-coupling to the mid-rail, and a top coupling to the top rail, the wall jack member including an outer support sleeve and a telescoping portion slidable within the support sleeve to extend to variable length between the mid coupling and the top coupling;
- and
- a jack screw coupled to the telescoping portion and coupled to the bottom rail to extend the telescoping portion of the vertical wall jack member to raise the top rail and the structural element of the roof when coupled thereto.
