Laterally and vertically adjustable foundation structure
View Patent ↗A foundation structure is made up of a screw that is vertically adjustable into a pile to a desired height, a ball joint connected to the screw, and load bearing components that can be adjusted on the ball joint in 3-dimensional space with respect to the position of the pile. The load bearing components include at least two plates that, between them, define a hollow slot into which an anchor bolt can be held in place vertically while still having allowance for lateral motion. A load bearing plate at the top of the structure can be laterally translated based on movement of the anchor bolt. The load bearing plate is removably couplable to the floor of a building. The structure allows for vertical, lateral, and angular adjustment, providing tolerance for foundation misalignments due to inconsistencies inherent to topography and/or offset between an intended and an actual point of installation.

a pile;
a threaded cap coupled to and positioned at an uppermost portion of the pile;
a telescoping screw inserted into the threaded cap, the screw being adjustably inserted to one or more vertical positions;

a capture plate, positioned at a side of the base plate remote from the ball joint, the capture plate having a second hollow slot that is (i) narrower in width than the head of an anchor bolt and (ii) capable of receiving a shank of the anchor bolt; and
a load bearing plate positioned at a side of the capture plate remote from the ball joint,
wherein the base plate, the capture plate, and the load bearing plate are, as a unitary structure, rotationally adjustable on the ball joint relative to the pile.
2. The foundation structure of claim 1 , wherein the ball joint is coupled to the telescoping screw, and the load bearing plate is detachably coupled to the capture plate.
3. The foundation structure of claim 1 , wherein the load bearing plate comprises a hole,
wherein the foundation structure further comprises an anchor bolt positioned within the first hollow slot and extending through the second hollow slot and the hole in the load bearing plate, and
wherein the anchor bolt is laterally translatable within the first hollow slot and the second hollow slot relative to the pile.
4. The foundation structure of claim 1 , further comprising a foundation mounting component positioned adjacent to and coupled to the load bearing plate at a side remote from the ball joint,
wherein the foundation mounting component is configured to be coupled to a flooring structure of a building.
5. A foundation structure comprising:
a pile;
a pile cap coupled to the pile;
a first adjustable element, wherein a first end of the first adjustable element is configured to be inserted into the pile cap such that the first end is adjustable from a first vertical position within the pile cap to a second vertical position within the pile cap;
a second adjustable element comprising a base portion and a body portion, the base portion being detachably coupled to a second end of the first adjustable element opposite to the first end, and the body portion being located at a side of the base portion remote from the first adjustable element, wherein the body portion is coupled to the base portion in a manner allowing the body portion to be pivoted so as to tilt with respect to a vertical axis passing through a center of the base portion and a center of the first adjustable element, the pivoting allowing for rotational movement of the body portion in at least one direction other than a vertical direction;
a fastening element;
a first plate coupled to the body portion of the second adjustable element at a side of the second adjustable element remote from the first adjustable element, the first plate having a first hollow slot extending laterally within the first plate, the first hollow slot being capable of receiving a portion of the fastening element; and
a second plate detachably coupled to the first plate at a side remote from the second adjustable element, the second plate having an opening capable of receiving a portion of the fastening element,
wherein the fastening element is positioned such that the fastening element extends vertically through the first hollow slot of the first plate and the opening of the second plate,
wherein the fastening element is laterally adjustable within the first hollow slot, and
wherein, when the fastening element is laterally adjusted within the first hollow slot, the second plate is laterally adjusted in correspondence with the lateral adjustment of the fastening element.
6. The foundation structure of claim 5 , wherein the first plate and the second plate, as a unitary structure, are pivoted on the second adjustable element relative to the pile.
7. The foundation structure of claim 5 , where the interior of the pile cap is threaded, the first adjustable element is threaded, and an interior of the base portion of the second adjustable element is threaded.
8. The foundation structure of claim 5 , further comprising:
an intermediate plate positioned between the first plate and the second plate, the intermediate plate having a second hollow slot.
9. The foundation structure of claim 8 , wherein the fastening element is an anchor bolt,
wherein a head of the anchor bolt is received in the first hollow slot and a shank of the anchor bolt is received in the second hollow slot, and
wherein the anchor bolt is capable of travelling laterally in the first hollow slot and the second hollow slot.
10. The foundation structure of claim 8 , wherein the first hollow slot is of a first width, the first width being at least at large as the width of a head of the fastening element, and
wherein the second hollow slot is of a second width, the second width being smaller than the width of the head of the fastening element and being at least at large as the width of a shank of the fastening element.
11. The foundation structure of claim 5 , wherein a length of the first hollow slot is greater than a diameter of the head of the anchor bolt.
12. The foundation structure of claim 5 , wherein the fastening element is adjusted in a lateral direction relative to the pile.
13. The foundation structure of claim 5 , wherein the first plate and the second plate are rotationally adjustable on the second adjustable element around the vertical axis of the first adjustable element.
14. A structure comprising:
a ball joint having a ball portion and a body portion, the body portion being rotatable with respect to the ball portion;
a first plate having a first slot that is (i) capable of receiving a head of a fastener and (ii) greater in length than a diameter of the head of the fastener;
a second plate, positioned at a side of the first plate remote from the ball joint, the second plate having a second slot that is (i) narrower in width than the head of an anchor bolt and (ii) capable of receiving a shank of the fastener; and
a third plate positioned at a side of the second plate remote from the ball joint, the third plate having a hole,
wherein the fastener is positioned within the first slot so as to extend through the second slot and the hole.
15. The structure of claim 14 , wherein the first plate is permanently affixed to the body portion of the ball joint.
16. The structure of claim 14 , wherein the third plate is detachably coupled to the second plate.
17. The structure of claim 14 , wherein the first plate, the second plate, and third plate, as a unitary structure, are pivoted on the ball joint with respect to the ball portion via rotation of the body portion around the ball portion.
18. The structure of claim 17 , wherein when the first plate, the second plate, and third plate are pivoted on the ball joint, the hole of the third plate is translated (a) from a first vertical position to a second vertical position, and (b) from a first horizontal portion to a second horizontal position.
19. The structure of claim 14 , wherein the fastener is laterally adjustable within the first slot and the second slot.
