Abstract
An embodiment of the system for forming a movable slab foundation as comprised by the present invention has a slab foundation, at least one substantially vertical support member, at least one support surface, and at least one support sleeve. The at least one support sleeve surrounds the at least one support member and is encased within the slab foundation and is capable of movement axially along the axis of the at least one support member. The at least one vertical support member is capable of rotation relative to the at least one support sleeve to restrict the movement of the at least one support sleeve downward relative to the at least one vertical support member, thereby maintaining the height of the at least One support sleeve and the slab foundation relative to the at least one support surface.
Claims15
A system for forming a movable slab foundation, the system comprising:
- a slab foundation;
- at least one support surface;
- at least one support member being substantially vertical and having a hollow body with first and second ends, the first end of the hollow body of the at least one support member abuttingly contacting the at least one support surface;
- at least one support sleeve surrounding the at least one support member, the at least one support sleeve being encased within the slab foundation and being capable of moving axially along an axis of the at least one support member, the at least one support sleeve having an opening through which the at least one support member is extendable, the opening being substantially geometrically complimentary to the at least one support member, and wherein the at least one support sleeve comprises an annular body with inner and outer surfaces, the inner surface of the annular body having a plurality of circumferentially spaced tabs extending radially inward to thereby define the opening in the at least one support sleeve therebetween;
- and
- the at least one support member being movable relative to the at least one support sleeve to offset the at least one support member from the opening of the at least one support sleeve and thereby restrict movement of the at least one support sleeve downward relative to the at least one support member.
A system for forming a movable slab foundation, the system comprising:
- a slab foundation;
- at least one support surface;
- at least one substantially vertical support member having an oblong-shaped body with first and second ends, the first end abuttingly contacting the at least one support surface;
- at least one support sleeve coupled to the slab foundation and surrounding the at least one support member, the at least one support sleeve having an annular body with inner and outer surfaces, the inner surface having a plurality of tabs extending radially inward from the annular body to thereby define an oblong-shaped opening, the oblong-shaped opening being substantially geometrically complimentary to the oblong-shaped hollow body of the at least one substantially vertical support member;
- and
- at least one lifting member operatively coupled to the at least one support sleeve to lift the at least one support sleeve and the slab foundation with respect to the at least one support surface such that the oblong-shaped body of the at least one substantially vertical support member is rotatable beneath the plurality of tabs to offset the at least one support member from the oblong-shaped opening and such that the at least one substantially vertical support member supports the at least one support sleeve and the slab foundation on the at least one support surface by the plurality of tabs.
A system for forming a movable slab foundation, the system comprising:
- a slab foundation;
- at least one support surface disposed beneath the slab foundation;
- at least one support sleeve having a hollow body encased within the slab foundation and disposed over the at least one support surface;
- a plurality of tabs extending radially inward from an inner surface of the hollow body of the at least one support sleeve to define an oblong-shaped opening therebetween;
- at least one support member having an oblong-shaped body with first and second ends, the oblong-shaped body being rotatable between first and second orientations with respect to the at least one support sleeve such that the at least one support member is passable through the oblong-shaped opening when arranged in the first orientation and offset from the oblong-shaped opening when in arranged in the second orientation such that when the oblong-shaped body is arranged in the second orientation, the first end of the oblong-shaped body abuttingly contacts the at least one support surface and the second end of the oblong-shaped body abuttingly contacts of plurality of tabs to support the slab foundation on the at least one support surface.
