The subject invention relates to a foundation system for a building. More specifically, the subject invention relates to a column assembly having an adjustable length for use in a building foundation system.
Typically, post-frame construction of buildings employs setting a series of pilings, usually made of wood, into the earth to define the perimeter of the building. Once the perimeter is set with the pilings, the building is framed in an upright position by connecting wall gifts to the adjacent pilings. A disadvantage of using wood piling is that they can break down in the earth over time and, in the case of chemically treated wood, the pilings can release chemicals into the ground. To overcome this particular problem, it is known in the art to use a two-piece piling assembly having an upper and a lower piling where the lower piling is reinforced concrete. Once the lower piling is set into the ground, the upper piling is attached to the upper piling and framing of the building commences.
To facilitate this type of construction, the upper and lower pilings can be connected at a hinge. The building walls are framed on the ground using the upper pilings. Following construction of the frame, each wall is rotated upward about the hinged connection and pinned for retention.
An example of this type of construction can be seen in U.S. Pat. No. 4,662,146 to Parry (“the '146 patent”). A lower hinge plate is connected to the top of the lower piling by fasteners. The hinge plate is a generally flat plate having a pair of opposing walls that extend vertically from edges of the hinge plate. A pair of opposing grooves are defined in front edges of the opposing walls, at the plate. Similarly, a pair of opposing holes are defined near the rear edges of the opposing walls. A shoe is attached to a lower end of the upper piling by fasteners. The shoe has a flat bottom and three walls that extend vertically from edges of the bottom. Two of the walls are opposing with the third wall extending between the rear edges. A pair of opposing pins extend from the lower front edge of the opposing walls, at the bottom. Similarly, a pair of opposing holes are defined in the opposing walls near the rear of the walls, spaced from the bottom.
The lower end of the lower piling is set in the ground, leaving the upper end of the piling exposed. On the ground, frames, made up of columns with rafters or beams, are connected together at a gable. The shoes are attached to the lower ends of the columns. Each frame is positioned such that the pins of the shoe are slid into the corresponding grooves on the lower hinge plate. Using a cable assembly, the frame is pulled into an upright position, rotating about the pins. This brings the holes on the shoe into alignment with the holes on the lower hinge plate. The frame is retained in an upright position by inserting pins through the holes.
This type of construction increases the amount of work that can be performed at ground level and could conceivably allow a single individual to hoist the frame into an upright position. However, it would still require more than one person to align the pins of the frame to the hinge plates of the lower pilings that are pre-set into the ground. The present invention is aimed at one or more of the problems identified above.
The invention is generally directed to an adjustable height column assembly for use in building foundation systems and methods of assembling adjustable height column assemblies.
In one aspect of the invention, a column assembly for use in a building foundation system is provided. The column assembly includes a height adjustment assembly for use in adjusting an overall length of the column assembly. The height adjustment assembly includes an access tube assembly and a rod assembly. The access tube assembly includes an inner surface and an outer surface. The inner surface defines a tube cavity that extends between a first end and a second end along a longitudinal axis. The rod assembly rotatably is coupled to the access tube assembly and extends outwardly from the second end along the longitudinal axis. A reinforcement assembly is coupled to the height adjustment assembly. The reinforcement assembly includes at least one reinforcement member that extends between a top portion and a bottom portion and is orientated with respect to the longitudinal axis. A column connector assembly is coupled to the reinforcement assembly and includes a baseplate that is coupled to the first end of the access tube assembly. The baseplate includes an opening extending therethrough that provides access to the tube cavity through the opening.
In another aspect of the invention, a column assembly used in a building foundation system is provided. The column assembly includes an upper column assembly and a lower column assembly that is coupled to the upper column assembly. The lower column assembly includes a height adjustment assembly for use in adjusting an overall length of the column assembly. The height adjustment assembly includes an access tube assembly and a rod assembly. The access tube assembly includes an inner surface and an outer surface. The inner surface defines a tube cavity that extends between a first end and a second end along a longitudinal axis. The rod assembly is rotatably coupled to the access tube assembly and extends outwardly from the second end along the longitudinal axis. A reinforcement assembly is coupled to the height adjustment assembly and includes at least one reinforcement member. The at least one reinforcement member extends between a top portion and a bottom portion and is orientated with respect to the longitudinal axis. A column connector assembly is coupled to the reinforcement assembly and the upper column assembly. The column connector assembly includes a baseplate that is coupled to the first end of the access tube assembly and includes an opening that is positioned with respect to the access tube assembly to provide access to the tube cavity through the opening.
In yet another aspect of the invention, a method of assembling a column assembly having an adjustable length is provided. The method includes coupling a sideplate to a baseplate to form a column connector assembly, coupling an access tube assembly to the baseplate, coupling a reinforcement member to the sideplate, and rotatably coupling a rod assembly to the access tube assembly. The sideplate includes a pair of engagement teeth extending through a slot formed in the baseplate. The baseplate includes an access opening extending therethrough. The access tube assembly includes an inner surface that defines a tube cavity extending between a first end and a second end along a longitudinal axis. The access tube assembly is positioned with respect to the access opening to provide access to the tube cavity through the access opening. The reinforcement member extends between a top portion and a bottom portion and is orientated with respect to the longitudinal axis. The top portion of the reinforcement member is positioned within a recess formed between the pair of engagement teeth to facilitate coupling the reinforcement member to the sideplate. The rod assembly is rotatable coupled to the second end of the access tube assembly such that a rotation of the rod assembly adjusts an overall length of the column assembly.
Other advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
a and 42b are partial perspective views of the piling assembly shown in
Corresponding reference characters indicate corresponding parts throughout the drawings.
With reference to the drawings and in operation, the present invention overcomes at least some of the disadvantages of known building foundation systems by providing a column assembly that includes an adjustable length. More specifically, the column assembly includes a height adjustment assembly for adjusting an overall length of the piling assembly to facilitate installation of the piling assembly for use in a building foundation system. In addition, the column assembly includes a lower column and an upper column that is coupled to the lower column and extends outwardly from the lower column along a longitudinal axis. The upper column and the lower column each include substantially similar cross-sectional areas such that the column assembly has a uniform cross-section along the longitudinal axis.
The column assembly also includes a threaded height adjusting bracket that allows for seamless foundation column height adjustment during construction and gives an aesthetically pleasing interior look for the building. The system starts each column location at a flush and level framing point repetitively. In addition, the column assembly includes a precast lower column assembly and exposed re-bar dowels encased in the lower column assembly to increase the uplift capacity over known columns. This sockets the precast member into the cast-in-place footing and decreases the overall weight of the precast column, making handling and shipping easier. In addition, an additional tie-plate has been positioned on the exposed re-bar to further stabilize the threaded adjustment rod and bracket during construction, making installation of the system easier for the crews by reducing the “wobbliness” of the column before the cast-in-place footing is poured. By providing an adjustable length column assembly having a uniform cross-section, the cost of installing a building foundation is reduced.
In addition, in one embodiment, the column assembly 100 includes a lower piling 112 hingedly connected to an upper piling 130. The lower piling has a first and a second end 114, 116 with a first longitudinal axis 118 extending therethrough. The upper piling 130 has a column 132 with a second longitudinal axis 134 extending therethrough.
A reinforcing cage 120 extends between the ends 114, 116, and concrete 122 encases the reinforcing cage 120. Many types of reinforcing cages 120 are known in the area of pilings. One type of reinforcing cage 120 is shown in
To provide an attachment scheme for the upper piling 130, a lower hinge 124 extends from the first end 114 and defines at least one lower first hole 126 on a first axis 128 that is spaced from the first end 114. The upper piling 130 has a column 132 and a second longitudinal axis 134 extending therethrough. Typically, the column 132 is comprised of wood, steel, aluminum or a composite. The upper hinge 136 extends from the column 132 and defines at least one upper first hole 138 on the first axis 128. The lower hinge 124 also defines a lower second hole 148, on a second axis 150 which is spaced transversely across the lower piling 112 from the lower first hole 126 and spaced from the first end 114. The upper hinge 136 also defines an upper second hole 152, on the second axis 150, which is spaced transversely across the upper piling 130 from the upper first hole 138.
In the early stages of building construction, the upper and lower hinges 136, 124 are partially interleaved, as shown in
Each of the upper and lower hinges 136, 124 include a first plurality of hinge knuckles 146, disposed about the first pin 144, where the knuckles 146 of the upper hinge 136 are interleaved with the knuckles 146 of the lower hinge 124. The knuckles 146 hold the first pin 144 in spaced relationship to the upper and lower pilings 130, 112 to transmit longitudinal forces between the pilings 130, 112 through the first pin 144. These forces include the loads resulting from the weight of the wall girts G, the roof, various other building materials and environmental factors. Similarly, the hinges 136, 124 include a second plurality of locking knuckles 156 that are disposed about the second pin 154 with the locking knuckles 156 of the upper hinge 136 interleaved with the locking knuckles 156 of the lower hinge 124. The locking knuckles 156 hold the second pin 154 in spaced relationship to the pilings 130, 112 to transmit longitudinal forces between the pilings 130, 112 totally through the first and second pins 144, 154. Therefore, the pins 144, 154 support the entire load provided by the upper pilings 130, wall girts G, the roof, various other building materials and environmental factors.
Each of the hinges 136, 124 includes a plurality of plates 158 that are in spaced and parallel relationship. A gap 169 is defined between each of the plates 158 to facilitate the upper hinge 136 interleaving with the lower hinge 124. The first hole 126 or 138 is defined through each of the plates 158, along the first axis 128. The second hole 148 or 152 is also defined through each of the plates 158, along the second axis 150, and spaced transversely across each of the plates 158 from the first hole 126 or 138 respectively. Furthermore, the plates 158 define a bottom edge 162 and end edges 164.
The lower hinge 124 is attached to the lower piling 112 at the bottom edge 162 and the holes 126, 148 are in spaced relationship from the lower piling 112. The upper hinge 136 includes a bottom 166 and a pair of opposing walls 168 that extend upward from the bottom 166, along the column 132. The bottom edge 162 of each of the plates 158 are attached to the bottom 166 of the upper hinge 136 and the end edges 164 of each of the plates 158 are attached to the opposing walls 168. Furthermore, the bottom 166 and the opposing walls 168 define a plurality of grooves 170 that extend in spaced and parallel relationship across the bottom 166 and into a portion of the walls 168, between each of the plates 158. The grooves 170 allow the hinge plates 158 of the lower hinge 124 to interleave with the plates 158 of the upper hinge 136.
Another embodiment of the piling assembly 200, shown in
A reinforcing cage 220, as shown in
To provide an attaching scheme, a lower hinge 224 extends from the first end 214 and defines at least one lower first hole 226 on a first axis 228 that is spaced from the first end 214. Similarly, the upper piling 230 has an upper hinge 236 that extends from the column 232 and defines at least one upper first hole 238 on the first axis 228. The lower hinge 224 also defines a lower second hole 248, on a second axis 250, and is spaced transversely across the lower piling 212 from the lower first hole 226 and spaced from the first end 214. Likewise, the upper hinge 236 defines an upper second hole 252, on the second axis 250, and is spaced transversely across the upper piling 230 from the upper first hole 238.
In the early stages of building construction, the upper and lower hinges 236, 224 are partially interleaved such that only a first pin 244 connects the upper hinge 236 to the lower hinge 224, along the first axis 228, and the second longitudinal axis 234, for the upper piling 230, is at an angle to the first longitudinal axis 218, for the lower piling 212. As a result, the columns 232 for the building can set tilted onto the ground. This position allows wall girts G to be connected to the columns 232 to facilitate the framing of an entire wall, or a partial wall, at ground level. Once the framing with the wall girts G is completed, the upper pilings 230 that form an entire wall, or a partial wall, are hoisted upward as a single unit, pivoting about the first pin 244 on the first axis 228. Then, the upper pilings 230 are hoisted upward, about the first axis 228, until the upper and lower hinges 236, 224 are completely interleaved with one another and the second axes 250, for the upper and lower second holes 252, 248 are aligned. When the hinges 236, 224 are completely interleaved, the first pin 244 extends through the upper and lower first holes 236, 226 on the first axis 228 to engage and support the hinges 236, 224. Likewise, a second pin 254 extends through the upper and lower second holes 252, 248 on the second axis 250 to engage and support the hinges 236, 224 when the longitudinal axes 218, 234 are aligned, as shown in
The hinges 236, 224 include a first plurality of hinge knuckles 246 that are disposed about the first pin 244, where the knuckles 246 of the upper hinge 236 are interleaved with the knuckles 246 of the lower hinge 224. The knuckles 246 hold the first pin 244 in spaced relationship to the pilings 212, 230 to transmit longitudinal forces between the pilings 212, 230 through the first pin 244. These forces include those resulting from the wall girts G, the roof of the building structure, and various other building materials and environmental factors. The hinges 236, 224 also include a second plurality of locking knuckles 256 that are disposed about the second pin 254 with the locking knuckles 256 of the upper hinge 236 interleaved with the locking knuckles 256 of the lower hinge 224. The locking knuckles 256 hold the second pin 254 in spaced relationship to the pilings 230, 212 for transmitting forces between the pilings 230, 212 through the first and second pins 244, 254.
Each of the knuckles 246, 256 on each of the hinges 236, 224 comprise a plurality of straps 272 that define a pin pocket 274 for encompassing at least a portion of the circumference of one of the pins 244, 254 extending therethrough. The pin pocket 274 defines the first hole 238, 226 in one of the knuckles 246 along the first axis 228. The pin pocket 274 also defines the second hole 252, 248 in another one of the locking knuckles 256 along the second axis 250 which is spaced transversely across one of the hinges 236, 224 from the first hole 238, 226. Grooves 270 are defined between each of the straps 272 of one hinge 236, 224 for interleaving of the upper and lower hinges 236, 224.
Additionally, the upper hinge 236 includes a bottom 266 and a pair of opposing walls 268 that extend from the bottom 266 and across the upper pilings 230. The first and locking knuckles 246, 256 are disposed between the walls 268 and the bottom 266. In the upper piling 230, the knuckles 246, 256 are disposed in spaced relationship on the upper hinges 236 across the upper piling 230 and are also in spaced relationship to the column 232. Similarly, the lower hinge 224 is attached to the lower piling 212 at the walls 268. The lower holes 226, 248 are in spaced relationship to the first end 214 of the lower piling 212.
In yet another embodiment, as shown in
Another type of reinforcing cage 320 is shown in
To provide an attachment scheme for the upper piling 330, the lower hinge 324 extends from the first end 314 and defines at least one lower first hole 326 on a first axis 328 that is spaced from the first end 314. The upper piling 330 has a column 332 and a second longitudinal axis 334 extending therethrough. Typically, the column 332 is comprised of wood, steel, aluminum or a composite. The upper hinge 336 extends from the column 332 and defines at least one upper first hole 338 on the first axis 328. The lower hinge 324 also defines a lower second hole 348, on a second axis 350 which is spaced transversely across the lower piling 312 from the lower first hole 326 and spaced from the first end 314. The upper hinge 336 also defines an upper second hole 352, on the second axis 350, which is spaced transversely across the upper piling 330 from the upper first hole 338.
In the early stages of building construction, the upper and lower hinges 336, 324 are partially interleaved, as shown in
Each of the upper and lower hinges 336, 324 include a first plurality of hinge knuckles 346, disposed about the first pin 344, where the knuckles 346 of the upper hinge 336 are interleaved with the knuckles 346 of the lower hinge 324. The knuckles 346 hold the first pin 344 in spaced relationship to the upper and lower pilings 330, 312 to transmit longitudinal forces between the pilings 330, 312 through the first pin 344. These forces include the loads resulting from the weight of the wall girts G, the roof, various other building materials and environmental factors. Similarly, the hinges 336, 324 include a second plurality of locking knuckles 356 that are disposed about the second pin 354 with the locking knuckles 356 of the upper hinge 336 interleaved with the locking knuckles 356 of the lower hinge 324. The locking knuckles 356 hold the second pin 354 in spaced relationship to the pilings 330, 312 to transmit longitudinal forces between the pilings 330, 312 totally through the first and second pins 344, 354. Therefore, the pins 344, 354 support the entire load provided by the upper pilings 330, wall girts G, the roof, various other building materials and environmental factors.
Each of the hinges 336, 324 includes a plurality of plates 358 that are in spaced and parallel relationship. A gap 369 is defined between each of the plates 358 to facilitate the upper hinge 336 interleaving with the lower hinge 324. The first hole 326 or 338 is defined through each of the plates 358, along the first axis 328. The second hole 348 or 352 is also defined through each of the plates 358, along the second axis 350, and spaced transversely across each of the plates 358 from the first hole 326 or 338, respectively. Furthermore, the plates 358 define a bottom edge 362 and end edges 364.
The lower hinge 324 is attached to the reinforcing cage 320 of the lower piling 312 along the bottom edge 362 and the lower holes 326, 348 are in spaced relationship from the lower piling 312. The upper hinge 336 includes a bottom 366 and a pair of opposing walls 368 that extend upward from the bottom 366, along the column 332. The bottom edge 362 of each of the plates 358 are attached to the bottom 366 of the lower hinge 324 and the end edges 364 of each of the plates 358 are attached to the opposing walls 368. Furthermore, the bottom 366 and the opposing walls 368 define a plurality of grooves 370 that extend in spaced and parallel relationship across the bottom 366 and into a portion of the walls 368, between each of the plates 358. The grooves 370 allow the plates 358 of the lower hinge 324 to interleave with the plates 358 of the upper hinge 336.

The lower hinge 424 also defines a lower second hole 448, on a second axis 450 which is spaced transversely across the lower piling 412 from the lower first hole 426 and spaced from the first end 414. The upper hinge 436 also defines an upper second hole 452, on the second axis 450, which is spaced transversely across the upper piling 430 from the upper first hole 438.
In the early stages of building construction, the upper and lower hinges 436, 424 are partially interleaved, as shown in
Each of the upper and lower hinges 436, 424 include a first plurality of hinge knuckles 446, disposed about the first pin 444, where the knuckles 446 of the upper hinge 436 are interleaved with the knuckles 446 of the lower hinge 424. The knuckles 446 hold the first pin 444 in spaced relationship to the upper and lower pilings 430, 412 to transmit longitudinal forces between the pilings 430, 412 through the first pin 444. These forces include the loads resulting from the weight of the wall girts G, the roof, various other building materials and environmental factors. Similarly, the hinges 436, 424 include a second plurality of locking knuckles 456 that are disposed about the second pin 454 with the locking knuckles 456 of the upper hinge 436 interleaved with the locking knuckles 456 of the lower hinge 424.

Therefore, the pins 444, 454 support the entire load provided by the upper pilings 430, wall girts G, the roof, various other building materials and environmental factors.
Each of the hinges 436, 424 includes a plurality of plates 458 that are in spaced and parallel relationship. A gap 469 is defined between each of the plates 458 to facilitate the upper hinge 436 interleaving with the lower hinge 424. The first hole 426 or 438 is defined through each of the plates 458, along the first axis 428. The second hole 448 or 452 is also defined through each of the plates 458, along the second axis 450, and spaced transversely across each of the plates 458 from the first hole 426 or 438 respectively.

The next embodiment of the piling assembly 500, shown in
This embodiment uses a height adjustable reinforcing cage 520, as shown in
Alternatively, the post-tensioning rods 523 can be threaded through corresponding holes on the base plate 537, each terminating at a flanged nut 539, as shown in
At the job site for constructing the building, if the height of the lower piling 512 needs to be reduced, the post-tensioning rods 523, lower hinge 524 and base plate 537 are initially removed and the concrete 522 is cut to the desired height. Following trimming of the lower piling 512, the rods 523, lower hinge 524 and base plate 537 are reassembled to the lower piling 512.
Additionally, a vertical hole, i.e., passage, (not shown) is cast into center of the concrete 522, extending between the first and second ends 514, 516 and along the first longitudinal axis 518. A vertical push rod 525 is attached to a bearing plate 541 with a nut 577 to create a push rod assembly 561, as shown in
To set the overall height of the lower piling 512, a threaded height adjustment mechanism 551, i.e., threaded shaft, having a head 535 disposed at one end thereof, is threadedly inserted through a center hole, i.e., passage, in the first end 514 at a threaded hole 543, i.e., threaded bore, in the lower hinge 524. Torque is applied to the height adjustment mechanism 551, via the head 535, to thread the height adjustment mechanism 551 into the lower piling 512 until the height adjustment mechanism 551 abuts the push rod. As torque is continued to be applied to the head 535, the mechanism 551 pushes against the push rod 525 of the push rod assembly 561, forcing the lower piling 512, and thus the uplift extensions 529 or flanged nuts 539, to move upward and away from the bearing plate 541. Once the desired height for the lower piling 512 is attained, concrete is poured into the hole in the earth, stopping at least two inches above the uplift extensions 529, and/or the base plate 537, to prevent the lower piling 512 from lifting out of the hole in the earth and to prevent the base plate 537 and/or the uplift extensions 529 from corroding. Once the concrete in the hole in the earth is adequately set, the height adjustment mechanism 551 is unthreaded and removed from the center hole in the lower piling 512. Finally, the hole in the earth is back filled with dirt, concrete or any other suitable material.
However, the jack piling assembly 512 is not limited to a post-tensioned concrete 522. A reinforced concrete 122, 222, 322, 422, such as those described in the previous four embodiments, or a pre-tensioned concrete can be used in lieu of post-tensioned concrete if they have a vertical hole, cast in the center along the first longitudinal axis 518, to facilitate height adjustment using the height adjustment mechanism 551 and the push rod assembly 561.
To provide an attachment scheme for the upper piling 530, the lower hinge 524, i.e., top plate, extends from the first end 514 and defines at least one lower first hole 526 on a hinge axis 528 that is spaced from the first end 514. The upper piling 530 has a column 532 and a second longitudinal axis 534 extending therethrough. Typically, the column 532 is comprised of wood, steel, aluminum or a composite. The upper hinge 536 extends from the column 532 and defines at least one upper first hole 538 on the hinge axis 528. The lower hinge 524 also defines a lower second hole 526, on a second axis 550 which is spaced transversely across the lower piling 512 from the lower first hole 550 and spaced from the first end 514. The upper hinge 536 also defines an upper second hole 552, on the second axis 550, which is spaced transversely across the upper piling 530 from the upper first hole 538.
In the early stages of building construction, the upper and lower hinges 536, 524 are partially interleaved, as shown in
Each of the upper and lower hinges 536, 524 include a first plurality of hinge knuckles 546, disposed about the first pin 544, where the knuckles 546 of the upper hinge 536 are interleaved with the knuckles 546 of the lower hinge 524. The knuckles 546 hold the first pin 544 in spaced relationship to the upper and lower pilings 530, 512 to transmit longitudinal forces between the pilings 530, 512 through the first pin 544. These forces include the loads resulting from the weight of the wall girts G, the roof, various other building materials and environmental factors. Similarly, the hinges 536, 524 include a second plurality of locking knuckles 556 that are disposed about the second pin 554 with the locking knuckles 556 of the upper hinge 536 interleaved with the locking knuckles 556 of the lower hinge 524. The locking knuckles 556 hold the second pin 554 in spaced relationship to the pilings 530, 512 to transmit longitudinal forces between the pilings 530, 512 totally through the first and second pins 544, 554. Therefore, the pins 544, 554 support the entire load provided by the upper pilings 530, wall girts G, the roof, various other building materials and environmental factors.
Each of the hinges 536, 524 includes a plurality of plates 558 that are in spaced and parallel relationship. A gap 569 is defined between each of the plates 558 to facilitate the upper hinge 536 interleaving with the lower hinge 524. The first hole 526 or 538 is defined through each of the plates 558, along the first axis 550. The second hole 548 or 552 is also defined through each of the plates 558, along the second axis 528, and spaced transversely across each of the plates 558 from the first hole 526 or 538 respectively. Furthermore, the plates 558 define a bottom edge 562 and end edges 564.
The lower hinge 524 is attached to the lower piling 512 at the bottom edge 562 and the holes 526, 548 are in spaced relationship from the lower piling 512. The upper hinge 536 includes a bottom 566 and a pair of opposing walls 568 that extend upward from the bottom 566, along the column 532. The bottom edge 562 of each of the plates 558 are attached to the bottom 566 of the upper hinge 536 and the end edges 564 of each of the plates 558 are attached to the opposing walls 568. Furthermore, the bottom 566 and the opposing walls 568 define a plurality of grooves 570 that extend in spaced and parallel relationship across the bottom 566 and into a portion of the walls 568, between each of the plates 558. The grooves 570 allow the plates 558 of the lower hinge 524 to interleave with the plates 558 of the upper hinge 536.
Additionally, a plurality of thru-holes 533 can be precast into the concrete 522 to facilitate attachment of various framing pieces F, concrete anchors, etc. to the lower piling 512.
A wall for a building can be constructed when more than one piling 512 is installed into holes in the earth at a building site. The method of erecting a wall for a building using a jack piling 512, i.e., lower piling, having a top and a bottom and a second piling 512 having a top and a bottom, comprises the steps of excavating a first hole and a second hole in the surface of the earth to a floor in each hole, placing the bottom of the jack piling 512 having a hinge axis 528 at the top onto the floor in the first hole, and placing the bottom of the second piling 512 having a hinge axis 528 at the top onto the floor in the second hole.
Then, the method includes the step of adjusting the position of the bottom of the second piling 512 upwardly and away from the floor of the second hole to establish the position of the hinge axis 528 of the second piling 512 prior to adjusting the position of the bottom of the jack piling 512. Next, the method includes the step of adjusting the position of the bottom of the jack piling 512 upwardly and away from the floor of the first hole to bring the hinge axis 528 of the jack piling 512 upwardly and into alignment with the hinge axis 528 of the second piling 512. The placement of jack pilings 512 into the earth is repeated until the preferred number of pilings 512 for a single wall is achieved.
One way to determine whether the proper height of each lower 512 piling is achieved is by using a grade ledge 557 that can be integrated onto each of the lower pilings 512, as shown in
Next, the method includes the step of pouring concrete into each of the holes in the earth to encase a portion of each of the pilings and to fix the alignment of the axes. It is preferable that the concrete extend at least two inches above the uplift extensions 529 to prevent lifting of the lower piling 512 and to prevent corrosion of the uplift extensions 529.
Next, the method includes the step of back filling each of the holes in the earth to the grade level 545 with a fill material. Then the method includes the step of regrading the surface of the earth to be level with a grade level 545. The grade level 545 is usually even with the grade axis of the lower pilings 512.
Then, the method includes the step of pivotally connecting a hinge axis 528 of an upper piling 530, to the hinge axis 528 of the lower piling 512 for each of the lower pilings 512. The next steps of the method include attaching framing pieces F across the upper pilings 530 to form an upper wall and pivoting the upper wall about the hinge axis 528 and into an upright position. Next, the method includes the step of securing the upper wall into the upright position.
Finally, the method includes the step of attaching framing pieces F across the lower pilings 512 to form a lower wall. The use of a grade level 545 on each lower piling 512 can be useful because the grade levels 545 can act as a ledge to align and support the lowermost framing pieces that are attached to the lower pilings 512.
In the illustrated embodiment, the lower column assembly 600 includes a precast concrete portion 606, a reinforcement assembly 608, an adjustment assembly 610, and a column connector 612. The lower column assembly 600 extends between a top end 601 and a bottom end 603 and has a length L1 that is measured along the longitudinal axis 604.
The reinforcement assembly 608 extends along the longitudinal axis 604 between a first end 614 and a second end 616 and includes a reinforcing cage, i.e. reinforcing cage 120, that extends from the first end 614 to the second end 616. The reinforcement assembly 608 also includes a length L2 measured between the first end 614 and the second end 616 along the longitudinal axis 604. The reinforcing cage 120 includes a plurality of reinforcement members (re-bar), i.e. reinforcing rods 123, that extend along the longitudinal axis 604, and a plurality of re-bar ties 618 that are spaced along the longitudinal axis 604. Each re-bar tie 618 is positioned between the reinforcing rod 123 such that adjacent reinforcing rods 123 are spaced a distance apart. In the illustrated embodiment, the reinforcing cage 120 includes four reinforcement rods 123.
The reinforcement assembly 608, a portion of the adjustment assembly 610, and a portion of the column connector 612 are positioned within the concrete portion 606. In the illustrated embodiment, the concrete portion 606 defines an outer surface of the lower column assembly 600 and has a substantially rectangular shape. In addition the lower column assembly 600 includes an outer surface that defines a substantially uniform cross-sectional area extending between the first end 614 to the second end 616. In the illustrated embodiment, the concrete portion 606 includes a length L3 measured along the longitudinal axis 604 from the first end 614 towards the second end 616. In the illustrated embodiment, the length L3 of the concrete portion 606 is approximately equal to the length L2 of the reinforcement assembly 608. In one embodiment, shown in
In the illustrated embodiment, the adjustment assembly 610 is coupled to the reinforcing cage 120 and extends from the first end 614 towards the second end 616 along the longitudinal axis 604. The adjustment assembly 610 includes an access tube assembly 619 that includes a center tube 620, a height adjustment tube 622, and a rod assembly 624. The center tube 620 extends from the first end 614 towards the second end 616 and is orientated between each of the reinforcing rods 123 along a centerline axis 626. More specifically, the center tube 620 extends through an opening defined in each re-bar tie 618 such that the center tube 620 is positioned between each reinforcing rod 123. The height adjustment tube 622 is coupled to the center tube 620 and extends outwardly from the center tube 620 along the centerline axis 626. The height adjustment tube 622 and the center tube 620 each include an inner surface that defines a cavity therein, and are coupled together such that an interior tube cavity is defined from an upper end of the center tube 620 to a lower end of the height adjustment tube 622. In addition, an upper end of the height adjustment tube 622 includes a sealing cap 628 that is configured to engage the center tube 620 to prevent a flow of concrete from entering the interior cavity during assembly.
Each reinforcing rod 123 is coupled to an outer surface of the height adjustment tube 622. Moreover, each reinforcing rod 123 includes a tapered portion 625 that extends towards the lower end of the height adjustment tube 622, and is coupled to the outer surface of the height adjustment tube 622 such that a portion of the height adjustment tube 622 extends outwardly from the second end 616 of the reinforcing cage 120.
The rod assembly 624 includes a rod such as, for example, vertical push rod 525 and a bearing plate 541 that is coupled to the rod 525 (shown in
In the illustrated embodiment, a portion of the rod 525 is inserted into the height adjustment tube 622 and is moveable with respect to the height adjustment tube 622 along the centerline axis 626. More specifically, the rod 525 is inserted into the height adjustment tube 622 and is rotatably coupled to the height adjustment tube 622 such that a rotation of the rod 525 moves the rod 525 along the longitudinal axis 604. For example, during installation of the column assembly 100, the rod 525 may be rotated in a first direction, represented by arrow 629, about the centerline axis 626 to move the rod assembly 624 outwardly from the height adjustment tube 622 to increase an overall length of the column assembly 100. In addition, the rod 525 may be rotated in an opposite second direction, represented by arrow 631, about the centerline axis 626 to move the rod assembly 624 inwardly towards the first end 614 to decrease the overall length of the column assembly 100.
In the illustrated embodiment, the rod 525 includes a recessed portion 630 defined at an upper end of the rod 525. The recessed portion 630 is sized and shaped to receive an adjustment tool 632 therein. In one embodiment, the recessed portion may include a hexagonal shape. In addition, the recessed portion may include any suitable shape to enable the adjustment assembly 610 to function as described herein. During installation, the adjustment tool 632 is inserted through adjustment assembly interior cavity and into the rod recessed portion to engage the rod 525 to facilitate rotating the rod 525 with respect to the height adjustment tube 622 to adjust the height of the column assembly 100. The adjustment tool 632 may also include an electric drill and/or pneumatic drill to facilitate rotating the rod 525 about the centerline axis 626. Alternatively, the adjustment tool 632 may include a recessed portion that is sized and shaped to receive the rod 525 therein to facilitate rotating the rod 525 about the centerline axis 626 to adjust the height of the column assembly 100. For example, in one embodiment, the rod 525 may have an outer surface that has a hexagonal shape that is inserted into a corresponding recess defined in the tool 632.
For example, during construction of the building foundation, the column assembly 100 is placed in the hole such that the bearing plate 541 contacts the bottom of the hole to support the piling assembly from the hole bottom. To adjust the height of the column assembly 100 from the ground surface, a user inserts the adjustment tool 632 into the interior cavity to engage the rod 525, rotates the adjustment tool 632 and the rod 525 to move the rod 525 along the longitudinal axis 604. The user may rotate the adjustment tool 632 in the first direction to move the rod assembly 624 outwardly and increase the overall length of the column assembly 100. As the rod assembly 624 is urged outwardly, the lower column assembly 600 moves upwardly away from the ground surface. The user may also rotate the adjustment tool 632 in the opposite second direction to move the rod assembly 624 inwardly to decrease the overall length of the column assembly 100 and to move the column assembly 100 closer to the ground surface. Once the desired length of the column assembly 100 has been achieved, the adjustment tool 632 is removed from the interior cavity and a portion of the hole is backfilled with concrete and/or dirt, securing the column assembly 100 from further adjustment or movement.
In the illustrated embodiment, the column connector 612 is coupled to the reinforcing cage 120 and to the upper column assembly 602, and extends outwardly from the reinforcing cage 120 along the longitudinal axis 604. The column connector 612 includes a base plate 634 and one or more side plates 636 that extend outwardly from the base plate 634. Each side plate 636 is configured to be coupled to the upper column assembly 602 to facilitate coupling the upper column assembly 602 to the lower column assembly 600 to form the column assembly 100. In the illustrated embodiment, the column connector 612 includes a pair of side plates 636, i.e. opposing walls 168. Referring to
In the illustrated embodiment, the base plate 634 includes a base member 640 and a pair of flanges 642 that extend outwardly from the base member 640. The base member 640 is substantially planar and extends between a first end 644 and an opposite second end 646 along a first axis 648, and between a first side edge 650 and an opposite second side edge 652 along a second axis 654 that is perpendicular to the first axis 648. In the illustrated embodiment, the column connector 612 includes a column width W measured between the first end 644 and the second end 646 along the first axis 648, and includes a column depth D measured between the first side edge 650 and the second side edge 652 measured along the second axis 654. In the illustrated embodiment, the column depth D is approximately equal to the column width W. In one embodiment, shown in
In the illustrated embodiment, a first flange 656 extends outwardly from the first side edge 650 and the second flange 658 extends outward from the second side edge 652. In addition, the base plate 634 has a cross-sectional area that is substantially similar to the cross-sectional area of the lower column concrete portion 606.
The base member 640 also includes an access opening 660 that extends through a center of the base plate 634, and a plurality of slots 662 that are defined along the second axis 654 and extend through the base member 640. The center tube 620 is coupled to the base plate 634 and is positioned with respect to the access opening 660 such that the access opening 660 is in flow communication with the interior cavity. Each slot 662 is sized and shaped to receive a corresponding pair of engagement teeth 638. Each pair of engagement teeth 638 are spaced apart to define a gap 663 therebetween. The gap is sized and shaped to receive a portion of the base member 640 defined between adjacent slots 662 such that the base member 640 contacts the side plate 636 as the side plate engagement teeth 638 are inserted into the corresponding slots 662 to facilitate coupling the base plate 634 to each side plate 636.
In the illustrated embodiment, the side plates 636 are orientated along the second axis 654 and are spaced a distance inwardly from the first and second ends 644 and 646, respectively, along the first axis 648. In addition, each side plate 636 is spaced an equal distance from the centerline axis 626. Each side plate 636 is also aligned with respect to a corresponding pair of reinforcing rods 123 and is coupled to the pair of reinforcing rods 123 such that a load path, represented by arrow 664, is defined through the side plate 636 to the reinforcement rod 123 to facilitate a transfer of bending forces, tensile forces, and/or compressive forces from the upper column assembly 602 to the lower column assembly 600. In addition, the engagement teeth 638 extend a distance from the base plate 634 such that the engagement teeth 638 are encased in the concrete portion 606.
The upper column assembly 602 includes a plurality of boards 668 that are coupled to each side plate 636 and extend outwardly from the base plate 634. In one embodiment, the boards are formed from wood. Alternatively, the boards 668 may be formed from steel, aluminum, or a composite. In the illustrated embodiment, the upper column assembly 602 includes a center board 670 and two outer boards 672. The side plate engagement teeth 638 facilitate alignment of the side plate 636 and the wood boards 668 with respect to the reinforcing rods 123 to facilitate a transfer of bending forces, tensile forces, and/or compressive forces from the wood boards 668 to the reinforcing cage 120 with each reinforcing rod 123 being encased with a minimum concrete cover.
Each board 668 is orientated along the second axis 654 and extends between the first side edge 650 and the second side edge 652. In the illustrated embodiment, the center board 670 is positioned between the pair of side plates 636, and the outer boards 672 are positioned between the side plates 636 and the first and second ends 644 and 646, respectively. The boards 668 and side plates 636 each include a plurality of holes that are sized and shaped to receive corresponding fasteners to facilitate coupling the boards 668 to the side plates 636. Each outer board 672 includes a recessed portion 673 that is defined along an outer surface. The recessed portion is sized and shaped to receive a corresponding side plate 636 therein. Moreover, the side plates 636 are spaced apart such that a lower portion of the center board 670 has a thickness that is larger than the thickness of a corresponding lower portion of each side outer board 672. By providing a center board 670 that has a larger cross-sectional area than the outer boards 672 at the point of connection between the column connector 612 and the wood boards 668, the amount of load transferred between the upper column assembly 602 and the lower column assembly 600 is increased.
In addition, each board 668 also includes a notch 674 defined along opposite ends of each board 668. Each notch is sized and shaped to receive a corresponding flange 642 therein such that a uniform cross-sectional area is defined along the longitudinal axis 604 from the upper column assembly 602 to the lower column assembly 600.
In the illustrated embodiment, the column assembly 100 also includes a splashboard bracket 676 (shown in
In the illustrated embodiment, a method of installing the column assembly 100 for use in erecting a building includes excavating a hole to a predetermined depth, providing the lower column 602 including height adjustment assembly 610, and inserting the lower column 602 into the excavated hole such that the bearing plate 541 contacts the bottom of the hole to support the column assembly 100 from the hole bottom. The adjustment tool 632 is inserted into the center tube 620 to engage the rod 525 and to rotate the rod 525 about the centerline axis 626 to adjust the height of the lower column assembly 600 with respect to the hole bottom. Once the desired height of the lower column 602 is achieve, the adjustment tool 632 is removed from the center tube 620 and concrete is poured into the hole and around the lower piling to backfill the hole to a predetermined depth. Once the concrete has set, the center board 670 and outer boards 672 are each coupled to the column connector to coupled the upper column assembly 602 to the lower column assembly 600 to form the column assembly 100. The splashboard bracket 676 is then coupled to the lower column assembly 600, and a splashboard is coupled to the splashboard bracket 676.
In the illustrated embodiment, the reinforcement assembly 608 includes a length L2 that is larger than the length L3 of the precast concrete portion 606 such that a portion of the reinforcement assembly 608 extends outwardly from the precast concrete portion 606. In addition, a precast/in-situ ready-mix concrete interface zone 686 is defined along a lower portion of the precast concrete portion 606 to facilitate coupling the precast concrete portion 606 to the in-situ cast concrete. The reinforcement members 123 extend outwardly from the concrete portion 606 to allow a portion of the reinforcement members 123 to be embedded in-situ concrete and/or backfill during installation to increase the uplift capacity of the column assembly 100.
In the illustrated embodiment, the threaded height adjusting bracket allows for seamless foundation column height adjustment during construction and gives an aesthetically pleasing interior look for the building. The system starts each column location at a flush and level framing point repetitively. The internal threaded adjustment bracket connects the building to the concrete footing and anchored the building against wind developed uplift loads. In one embodiment, the swaged-threaded tube is removed, the reinforcement bars are straightened and lengthened, a tie plate and a lower support plate are added, and a portion of the precast concrete is removed. By shortening the cast length of the precast lower column and using the re-bar dowels already encased in the member, the uplift capacity is increased and the structural design becomes more effective. This sockets the precast member into the cast-in-place footing better than the previous design and decreases the overall weight of the precast column. This makes handling and shipping easier. In addition, the additional tie-plate has been positioned on the exposed re-bar to further stabilize the threaded adjustment rod and bracket during construction. This new design makes installation of the column assembly easier for the crews by reducing the “wobbliness” of the column before the cast-in-place footing is poured. The lower support plate will have an attached nut or threaded section to connect to the threaded adjustment rods.
