The present inventive concept relates to a hydraulic lift caisson to lift buildings and other large and/or heavy objects. More particularly, but not exclusively, this inventive concept relates to a hydraulic lift caisson to lift buildings off the ground or off a cellar floor to extreme heights in one continuous stroke.
Buildings are sometimes required to be moved from one location to another or may be required to be raised due to an unstable foundation which needs to be reinforced. In these cases the building being required to be moved must first be raised off the ground before being able to be moved. However, raising and moving a building is a very complex task with great risks to the building's structure, including unrepairable damage, if not performed properly.
Conventionally raising a building has been performed with a significant number of hand jacks and manpower to raise the building in slight increments at a time. Even with this process the building often ends up being raised unevenly, causing cracks or more significant damage to the foundation of the building and to the building itself. Once a foundation of a building is damaged repairs to this foundation are extremely difficult and often impossible to achieve. Similarly, once a building's structure becomes damaged repairs to the building are extremely difficult and often impossible to achieve.
U.S. Pat. No. 9,022,355 by Pigeon is directed to a hydraulic jack attachment for quickly and safely jacking up high clearance objects. The hydraulic jack attachment includes a base support 20, a footing 30, and a linkage tube 40 interlocked with a lifting member 50 and positioned within the base support 20. A hydraulic jack 12 can be placed into a lower end 22 of the base support 20 via an access opening 23. When the jack 12 is lifted, it will force the linkage tube 40 and lifting tube 50 upwards. A lifting head 60 on the upper end 51 of the tube 50 will press against and force an object upward. This hydraulic jack attachment is not configured to lift heavy objects, such as a building, cannot provide the stability required to lift a building, and cannot be provided in plurality while simultaneously controlling each of the plurality of hydraulic jack attachments to lift such heavy objects evenly.
KR 20090006548A by Son Jang HYEOK is directed to a structure lifting device to lift a structure to the appointed height without dismantling the structure, and to regulate the lifting height of a structure easily by fixing, using a locking nut, after lifting up to the appointed height. This structure lifting device comprises a plurality of support columns 100 composed of a circular steel pipe fixed to the ground, a plurality of full thread bolts 200 inserted within the support column 100 and installed to make each end exposed to the upper part, and an end plate 300 provided with a plurality of through holes on its corners to penetrate the full thread bolts and attached to the top of the support column, and a hydraulic jack 400. This lifting device cannot lift heavy loads to great heights because it relies solely on the structural strength and stability of the plurality of the threaded rods, which are relatively slender and, thus, are not suitable to support heavy loads in compression. Also, this lifting device does not have the structural reliability to maintain a constant lifting capacity because the load carrying capacity and stability of the plurality of threaded rods in compression inherently decreases as the height of the lift increases.
Accordingly, there is a need for a lift caisson that can lift heavy buildings.
There is also a need for a lift caisson that can lift heavy buildings evenly to prevent damage to foundations and building structures to unlimited heights.
There is also a need for a lift caisson that can lift a heavy building from its foundation or from the ground.

Hereinafter, one or more exemplary embodiments of the present general inventive concept will be described in detail with reference to accompanying drawings.
Exemplary embodiments of the present general inventive concept are directed to a hydraulic lift caisson to lift buildings (or other large and/or heavy objects). More particularly, but not exclusively, this inventive concept relates to a hydraulic lift caisson to lift buildings off the ground or a cellar floor in which such buildings are built on. The exemplary embodiments will be described in detail below with reference to
Within the outer steel pipe 1001 can be provided a steel lifting post 1002. The steel lifting post 1002 preferably extends the entire length of the outer steel pipe 1001 and is preferably formed to be 16 inches by 16 inches square, with a wall thickness of ⅝ inch. The steel lifting post 1002 can be provided in 10 feet sections or can be formed as one single piece to a desired length. The desired length of the steel lifting post 1002 will depend on how deep the requirement will be to insert the steel lifting post 1002, within the outer steel pipe 1001, into the ground in order to rest the bottom end of the outer steel pipe 1001 securely on solid rock underground while a top end extends up past the ground level in which a building rests. A plurality of steel lifting posts 1002 can be connected together to provide one elongated steel lifting post 1002, as will be described in more detail below. Alternatively, the steel lifting post 1002 can have a different area and wall thickness depending on the size and weight of a building to be lifted. Also, the steel lifting post 1002 can be formed of alternative types of metals which will withstand several tons of weight. The steel lifting post 1002 is preferably disposed to extend along the inner center of the outer steel pipe 1001. The steel lifting post 1002 preferably includes a top lifting plate 1003 formed at a first (top) end thereof, which is configured to extend out through the first (top) end of the outer steel pipe 1001 when the hydraulic lift caisson 1000 is in operation, as will be described in more detail below.
The outer steel pipe 1001 can also include a plurality of threaded lifting rods 1004 disposed therein and extending along the entire length therein. The threaded lifting rods 1004 are preferably disposed to surround the steel lifting post 1002 and are preferably also formed of steel. The threaded lifting rods 1004 can alternatively be formed of another type of metal which will withstand the weight of several tons. According to an example embodiment, the plurality of threaded lifting rods 1004 can include twelve threaded lifting rods 1004. Alternatively, the threaded lifting rods 1004 can be provided in a certain number depending on the size and weight of a building to be lifted by the hydraulic lift system 1000.
Referring to
At each of the four corners of the anchor plate 1006 can be disposed a hydraulic jack 1010, which is described in more detail below. A combined total hydraulic jacking capacity of the four hydraulic jacks is greater than the total weight of the load to be lifted. In an example embodiment of the present inventive concept, each of the hydraulic jacks 1010 can be configured to lift 150 tons of weight. Alternatively, the hydraulic jacks 1010 can be configured to lift an amount of weight that is greater than the building intended to be lifted.
Referring to
After the first ends of the threaded lifting rods 1004 are inserted through the respective holes 1006b in the jacking plate 1008 a respective jacking plate full load nut 1004b can be threaded thereon to force the threaded lifting rods 1004 to be lifted when the jacking plate 1008 is lifted by the hydraulic jacks 1010. With this configuration when the hydraulic jacks 1010, which are resting on the top surface of the anchor plate 1006, lift the jacking plate 1008, the threaded lifting rods 1004 will be lifted upward together with the jacking plate 1008, which will in turn also raise the anchor plate locking nuts 1004a upward away from the anchor plate 1006.
The hydraulic jacks 1010 disposed on each anchor plate 1006 are configured to be operated in sync to simultaneously lift the four corners of the jacking plate 1008 such that the jacking plate 1008 remains in a horizontal position while being lifted. The hydraulic jacks 1010 preferably lift the jacking plate 1008 slowly and in approximately four inch increments. After the hydraulic jacks 1010 simultaneously lift the jacking plate 1008 by approximately four inches, which will cause the threaded lifting rods 1004 to be lifted upward by approximately four inches, which will in turn cause the base lifting plate 1020 and steel lifting post 1002 to be lifted together by the same four inches, the anchor plate locking nuts 1004a will also be raised off the anchor plate 1006 by the same four inches. Once the anchor plate locking nuts 1004a have been raised by four inches away from the anchor plate 1006 the anchor plate locking nuts 1004a can be threaded downward until each of the anchor plate locking nuts 1004a is once again resting on the top surface of the anchor plate 1006. At this point the steel lifting post 1002 will have been securely lifted upward with respect to the outer steel pipe 1001 and will remain in this position since the anchor plate locking nuts 1004a will be securely seated on the anchor plate 1006, thus preventing the threaded lifting rods 1004 from sliding downward due to the weight of the building or other heavy object being lifted. At this point the hydraulic jacks 1010 can be simultaneously retracted back to their starting positions, which will cause the jacking plate 1008 to be lowered to its original position. Once the jacking plate 1008 is lowered back to its original position the jacking plate full load nuts 1004b can be threaded downward until they are again resting on the top of the jacking plate 1008. This sequence of operations can be continuously repeated until the building is lifted to the desired height.
As pointed out above, the hydraulic jacks 1010 can continue to lift the jacking plate 1008 upward by approximately four inches at a time, which will in turn lift the steel lifting post 1002 upward by an equal amount. As a result of the hydraulic jacks 1010 continually lifting the jacking plate 1008, the threaded lifting rods 1004, the base lifting plate 1020 and the steel lifting post 1002 simultaneously by approximately four inches, and then threading the anchor plate locking nuts 1004a back down onto the surface of the anchor plate 1006, and then retracting the hydraulic jacks 1010 back to their resting position, and then threading the jacking plate full load nuts 1004b back down onto the surface of the jacking plate 1008, and then repeating these steps, the building, which will be sitting on a plurality of top lifting plates 1003 welded to the first (top) end of the steel lifting posts 1002, will continue to be lifted away from the ground until the desired height is achieved.
Operations of the hydraulic lift caisson 1000 according to an example embodiment of the present inventive concept will now be described in detail below.
Referring back to
A hydraulic lift caisson 1000 can be positioned under each of the CRBs used under the intended building to be lifted. Once each of the CRBs has a hydraulic lift caisson 1000 disposed thereunder, the hydraulic jacks 1010 used with each of the plurality of hydraulic lift caissons 1000 can be activated simultaneously to lift their respective jacking plates 1008 in unison by approximately four inches, which will cause the threaded lifting rods 1004 and respective steel lifting posts 1002 to lift the respective CRBs upward, thus lifting the building upward evenly. Each time the four hydraulic jacks 1010 for each of plurality of hydraulic lift caissons 1000 lifts the corresponding jacking plate 1008 up by approximately four inches, the anchor plate locking nuts 1004a can be threaded downward along the corresponding threaded lifting rod until the anchor plate locking nuts 1004a are again resting on the top of the anchor plate 1006. Then the hydraulic jacks 1010 can be retracted to their original position causing the jacking plates 1008 to be lowered back to their original position. Then the jacking plate full load nuts 1004b can be threaded downward to once again rest on the top surface of the jacking plate 1008. This sequence of operations can be continuously repeated until the building being lifted is raised to a desired height for the intended purpose. Moreover, the building being lifted by the plurality of hydraulic lift caissons 1000 will be evenly lifted in one continuous stroke.
According to this example embodiment, the support column base plate 2012 is rectangular in shape and can include the first support column 2001a disposed adjacent to the first end thereof and the second support column 2001b disposed adjacent to the second end thereof. In the alternative case where the support column base plate 2012 is square or round in shape, or any other utilitarian shape, the first and second support columns 2001a, 2001b can be disposed at different locations on the top surface of the support column base plate 2012, or more than two support columns 2001 can be disposed at different locations on the top surface of the support column base plate 2012 as may be required for heavier buildings or other objects to be lifted, or in order to accommodate different shaped terrain in which the support column base plate 2012 is to be placed thereon. In order to maintain brevity of the detailed description herein only first and second support columns 2001a and 2001b will be described herein, and therefore other components which work together with the support columns 2001a and 2001b will be described to correspond with only the pair of support columns 2001a and 2001b. However, it is to be noted that other components to be described herein can be configured to correspond with the number of support columns 2001 used in order to work together with the number of support columns being used, without departing from the spirit and scope of the overall present inventive concept as described herein.
Above and directly aligned with the support column base plate 2012 can be disposed a lifting post base plate 2014. The lifting post base plate 2014 preferably has the same shape and surface area as the support column base plate 2012 and can include holes extending therethrough which conform with the shape the support columns 2001a and 2001b, respectively, to receive a respective one of the support columns 2001a and 2001b therethrough. The lifting post base plate 2014 is configured to slide along the entire length of the support columns 2001.
At second ends of the support columns 2001a and 2001b can be fixed an anchor plate 2006 such that the support columns 2001a and 2001b extend in parallel from the support column base plate 2012 to a bottom surface of the anchor plate 2006, wherein the lifting post base plate 2014 can slide therebetween. The lifting post base plate 2014 and the anchor plate 2006 can also include at least two rod holes extending therethrough to receive a respective threaded rod 2004 therethrough. Preferably a first one of the at least two rod holes extending through the lifting post base plate 2014 and the anchor plate 2006 is disposed adjacent to the first support column 2001a and a second one of the at least two holes extending through the lifting post base plate 2014 and the anchor plate 2006 is disposed adjacent to the second support column 2001b. However, it is to be noted that more than two rod holes can be formed through the lifting post base plate 2014 and the anchor plate 2006 to receive a corresponding threaded rod 2004 therethrough. For example, as illustrated in
First ends of the threaded rods 2004 extend through each respective rod hole formed through the lifting post base plate 2014. A threaded nut 2004c can be threaded onto a corresponding first end of the threaded rods 2004 to prevent the threaded rods 2004 from sliding out of the respective rod holes formed through the lifting post base plate 2014. Further, a threaded nut 2004a can be threaded onto a corresponding second end of the threaded rods 2004 to prevent the threaded rods 2004 from sliding out of the respective rod holes formed through the anchor plate 2006.
Referring back to
A top surface of the lifting post base plate 2014 can include a lifting post 2002 fixed to a center portion thereof. The lifting post 2002 preferably extends in parallel with and between the support columns 2001a and 2001b. The lifting post 2002 is also preferably disposed between the threaded rods 2004. Both the anchor plate 2006 and the jacking plate 2008 can include a hole formed therethrough to receive the lifting post 2002 therethrough. At the top end of the lifting post 2002 can be fixed a top plate 2003. The top plate 2003 is configured to press against a bottom surface of a building or other heavy object to lift the building or other heavy object, as described in more detail below. The support columns 2001a and 2001b, the lifting post 2002, the support column base plate 2012, the lifting post base plate 2014, the anchor plate 2006, the threaded rods 2004 and the jack plate 2008 can be formed of steel, or any other metal or hard rigid material that will withstand several tons of weight.
Between the anchor plate 2006 and the jacking plate 2008 can be disposed one or more hydraulic jacks 2010. According to the present example embodiment as illustrated in
Once the hydraulic jacks 2010 are fully expanded the threaded nuts 2004a can be threaded further along the respective threaded rods 2004 such that the lifting post base plate 2014 and lifting post 2002 will remain at their newly raised positions while the threaded nuts 2004a are seated on the top surface of the anchor plate 2006. At this point the hydraulic jacks 2010 can be released from hydraulic pressure to retract back to their original positions, which will cause the jack plate 2008 to drop down back toward the anchor plate 2006 while the lifting post base plate 2014 and lifting post 2002 remain at their newly raised positions. Once the jacking plate 2008 is dropped back to its original position with respect to the anchor plate 2006 the threaded nuts 2004b can be threaded further along their respective threaded rods 2004 to once again be seated on the jacking plate 2008 while the lifting post 2002 and top plate 2003 remain at their newly raised position. To further raise the lifting post 2002 and top plate 2003 the hydraulic jacks 2010 can once again be operated to expand and lift the jacking plate 2008. This process can be repeated until the lifting post 2002 and top plate 2003 are raised to a desired position, thus lifting the building or other heavy object to the desired height. The hydraulic jacks 2010 disposed on each anchor plate 2006 are configured to be operated in sync to simultaneously lift the jacking plate 2008 such that the jacking plate 2008 remains in a horizontal position while being lifted. The hydraulic jacks 2010 can lift the jacking plate 2008 slowly and in various stroke lengths.
It is to be noted that the number of support columns, threaded rods, etc., can be increased or decreased as desired to accommodate the size and weight of a building to be lifted, without departing from the spirit and scope of the overall present inventive concept.
Although a few embodiments of the present general inventive concept have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the appended claims and their equivalents.
The present inventive concept is a continuation-in-part (CIP) of and claims benefit of priority under 37 C.F.R. 1.121(f) to co-pending U.S. patent application Ser. No. 18/204,565, filed Jun. 1, 2023, the entire disclosure of which is hereby incorporated by reference herein.
