The invention relates to materials and methods for providing various low environmental impact foundation components and systems for structural support.
The search for less expensive, more effective, and more environmentally sound methods of creating building foundations for new construction on previously undisturbed or undesirable building sites has led to the development of the pinned foundation system and structure load transfer systems. These systems are an important advance in foundation engineering and have expanded the availability of and minimized construction impacts on many sites for surface structures.
These multiple pile foundation systems, are applicable to a wide variety of site and soil conditions and a wide variety of surface structures (buildings). The multiple pile foundation system can reduce the need for site excavation, drainage control, and soil backfill by transferring load from a portion of a structure to the ground.
There is a need for foundations that have minimal environmental impact in many areas. The effects of site manipulation on undisturbed soil are permanent and not restricted to the individual sites on which they occur. Altering a site with the use of large machinery, extensive excavation and fill techniques, and the resulting redirection of drainage patterns and water tables damages the biological make up, structural integrity, and pre-existing drainage characteristics of the site, the soil, and its surroundings. This in turn can have damaging effects “downstream”, where the accumulation of unwanted eroded material in streambeds can alter plant and animal habitats.
There is therefore a need to minimize excavation in all construction sites, particularly those in sensitive ecosystems, areas with a high-water table or poor soil drainage, or areas in which flooding is repetitive. Challenges transferring load from buildings to the soil in such construction sites is common and the present invention was developed to fulfill these objectives.
U.S. Pat. Nos. 5,395,184 and 8,714,881 are incorporated by reference herein.
The inventor has found that incorporating multiple pile foundation components into structure system that is connected to, or otherwise part of the foundation, can further reduce the need for excavation and thus preserve existing contours and drainage properties of the land.
In one aspect is provided a foundation system comprising a support frame and a plurality of foundation components connected to the frame at selectively spaced intervals for support of a building. The frame extends in a substantially horizontal or level direction to provide load support to a building structure connected thereto. Each foundation component comprises one or more openings configured to receive and fixedly engage an angularly driven pile. The openings are positioned within the foundation component to define an angular relationship between the component, support frame and one or more piles.
Yet another aspect is provided a foundation system comprising a beam, a plurality of foundation components, and at least one pile connected to each component. The beam is a substantially horizontal element of a foundation and the beam provides support, shape, seat, and attachment to a building structure attached thereto. The plurality of foundation components comprises a beam-engaging shaped metal housing with a plurality of selectively positioned openings. At least one of the openings is configured to receive a pile and the support component is connected to the beam. The pile is positioned through the opening of the foundation component.
Yet another aspect is provided a foundation system comprising a beam, at least one pile connected to the beam, and a locking component configured to be connected to the beam. The beam is a substantially horizontal or level component of a foundation configured to provide level load support to a structure wherein said load includes weight and natural forces, including wind, heave, seismic, and flooding forces. At least one pile connected to the beam is positioned through the opening of the beam. The locking component configured to be connected to the beam comprises a tightening mechanism operable to develop a compression force between said locking component and said pile(s).
The above and further aspects of this invention are further discussed with reference to the following description in conjunction with the accompanying drawings, in which like numerals indicate like structural elements and features in various figures. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating principles of the invention.
The figures depict one or more implementations of the inventive devices, by way of example only, not by way of limitation.
In one aspect is provided a foundation integral support system comprising a supporting frame and a plurality of foundation components connected to the frame elements at selectively spaced intervals for support thereof. The frame extends in a substantially horizontal or level direction to provide load support to a building structure connected thereto. Each support component comprises one or more openings configured to receive and fixedly engage an angularly driven pile. The openings are positioned within the foundation component to define an angular relationship between the foundation component, support frame and one or more piles.
In various embodiments, the foundation integral support system can reduce the need for site excavation, drainage control, and soil backfill by transferring load from one or multiple portions of a structure to the ground without digging. The foundation systems are minimal excavation foundations, also known as low impact foundations, or are part of minimal excavation foundations or low impact foundations. A minimal excavation foundation is a building best management practice (BMP) that minimizes mass grading and site disturbance by distributing a building's structural load onto piles. The foundation integral support systems described herein can reduce runoff and improve water quality by not substantially requiring stormwater management systems. When stormwater is absorbed into soil, it is filtered and ultimately replenishes aquifers or flows into streams and rivers with minimal downstream flooding, stream bank erosion, increased turbidity (muddiness created by stirred up sediment) from erosion, habitat destruction, contaminated streams, rivers, and coastal waters. In summary, the foundation integral support systems reduce the need to grade land, minimize soil compaction arising from use of heavy excavation equipment, and preserves the natural flows of stormwater.
Any number of foundation integral components illustrated herein may be used. The component can comprise, for example, a locking plate comprising one or more openings having an inner perimeter formed as a non-circular ellipse and configured to receive the pile. A nonlimiting example of a locking plate is shown in
In various embodiments, the foundation integral construction components comprise (i) a top plate or surface in any orientation available as long as its configured to enable the locking function; (ii) a locking component configured to be connected to said top plate or surface by one or more connectors, comprising a tightening mechanism operable to develop a compression force between said top plate or surface and said locking component, in which the locking component is configured to lock the pile within the one or more openings when the tightening mechanism is utilized such that the distance between the top plate or surface and the locking component is reduced by the compression force thereby locking the pile in the one or more openings.
In various embodiments, the support frame comprises at least one beam member wherein the at least one beam member is set within one of the foundation components. The beam member can be made of various materials. In one embodiment, the beam member is made of wood.
In various embodiments, the support frame distributes a structural load onto the foundation components and piles. There can be a relationship between the structural load and (i) one or more of the number of foundation components and (ii) the locations of the foundation components.
In yet another aspect is provided a supporting frame system comprising a beam, a plurality of foundation components, and at least one pile connected to each foundation component. The beam is a substantially horizontal or level element of a foundation and the beam provides support, shape, seat, and attachment to a building structure attached thereto. The plurality of foundation components comprises a beam-engaging shaped metal housing or saddle shaped metal housing with a plurality of selectively positioned openings. At least one of the openings is configured to receive a pile and the foundation component is connected to the beam. The pile is positioned through the opening of the foundation component.
In some embodiments, the foundation structural support system comprises two piles. In some embodiments, the two piles are positioned at a predetermined angle relative to the supported structure. The foundation system can comprise two beams, with each of the two beams is set within one of the support components. In various embodiments, the foundation system further comprises a bracing connector configured to connect the foundation component to the beam.
In some embodiments, the beam is horizontal or level or at an angle to the surface of the soil. In various embodiments, the support system distributes a structural load onto the foundation components and integral piles. The positioning of the foundation components and piles may be configured to distribute various loads provided by different soils and building structures. For example, there can be a relationship between the structural load and one or more of the number of foundation components and the locations of the foundation components.
In yet another aspect is provided a foundation system comprising a beam, at least one pile connected to the beam, and a locking component configured to be connected to the beam. The beam is a substantially horizontal or level component of a foundation configured to provide load support to a structure wherein said load includes weight natural forces, including wind, heave, seismic, and flooding forces. At least one pile connected to the beam is positioned through the opening of the beam. The locking component configured to be connected to the beam comprises a tightening mechanism operable to develop a compression force between said beam and said locking component.
In some embodiments, the locking component is configured to lock the pile within the opening when the tightening mechanism is utilized such that the distance between the beam and the locking component is reduced by the compression force, thereby locking said pile in the opening.
The structural support system can be configured to be placed on a hill, on a substantially level or terraced site.
The structural support system can be comprised of wood and steel. Alternatively, the structural support system can be comprised of steel. The beam can be comprised of wood. Alternatively, the beam can be comprised of steel.

This exemplary embodiment is illustrated in
In this exemplary installation, the tube component (101) is set substantially plumb within a shallow cavity in a minimally disturbed suitable battered pile bearing soil. Micro-piles driven through the tube and internal locking plate, and into the soils provide structural support in bearing, uplift, rotational, shear and lateral loads. Once the micro piles are driven, the locking plate is tightened to bind the piles against their corresponding elliptical holes in the tube. In the component depicted, the locking plate is supported within the tube in a specific location to facilitate easy sliding of the various piles by a tightening bolt (107) which passes through a resisting plate (108) set within the tube through slots (109). Tightening of the bolt and the consequent binding of the piles is achieved by tightening the nut (110) reached through the access hole (111). Once set the steel column can be further enhanced with the introduction of a wood member (112) sized to slip easily within the tube shape. The wood member rests on a stand-off base (113) configured to separate the wood from the tightening nut while still allowing access to the nut through the access hole.
This column component provides various benefits. The benefits include multiple allowable shapes, e.g., rectangular, circular, or other structural tube shapes, such as those described in FIG. 10 of U.S. Pat. No. 5,395,184, incorporated by reference herein. The components can be made of steel or other suitable material without changing the essential function defined above. As with the previous art incorporated by reference, the suitable soils may include any material that will provide a load capacity transfer and can be penetrated by the piles, including those that may require predrilling. The piles can be of a wide variety of cross sections and suitable materials per the prior art as well, and they may also include integral deformations (115) or turnings (117), on their surface or internally, which either improve driving, or load resistance or both, as shown in

In this exemplary installation, the continuous integral beam component (701) is set level using temporary blocks and shims set on site grade substantially level. Micro-piles driven through the beam and internal locking plate (705), and into the soils, provide structural support in bearing, uplift, rotational, shear and lateral loads. Once the micro piles are driven, the locking plate is tightened to bind the piles against their corresponding elliptical holes in the beam. In the component depicted, the locking plate is supported within the tube beam in a specific location to facilitate easy sliding of the various piles by a tightening bolt (707) which passes through a hole (708) in the top of the tube beam. Tightening of the bolt and the consequent binding of the piles is achieved by tightening the nut (709). An optional horizontal tie cross-beam (710) is also shown, allowing for the connection of the tube beam to a corresponding parallel tube beam on the opposite side of the structure. The beam(s) (701) may be installed individually without this integrating cross-tie, or if tied, comprise a “whole” pre-configured frame, that is craned into a site as a complete assembly prior to leveling and the driving of micro-piles.
