Definitions

  • the present invention is directed to construction techniques involving anchoring systems.
  • a building is subject to extreme forces from nature. High winds and earthquakes, in particular, cause forces that place considerable strain on the stability of a building. Proper distribution of these forces is critical to ensure the stability of a structure.
  • At the core of building stability is the building's foundation and thus securing the walls of a building to the foundation greatly improves structural performance.
  • a lateral bracing system typically includes vertical studs spaced from each other and affixed to horizontal top and bottom plates.
  • the bottom plate is typically anchored to the floor diaphragm or foundation.
  • the bracing system typically further includes sheathing affixed to the studs, upper plate and/or lower plate to increase structural response to lateral forces.
  • the sheathing used is generally oriented strand board (OSB) or plywood, but fiberboard, particleboard and drywall (gypsum board) are also used.
  • OSB oriented strand board
  • light-frame construction wall sections may include prefabricated shearwall sections, which can be positioned between the vertical studs and affixed to the studs and the top and bottom connecting plates.
  • the sheathing or prefabricated panels can also be placed adjacent door and window frames to improve the response to lateral forces at these locations.
  • Shearwalls were developed to counteract the potentially devastating effects of natural phenomena such as seismic activity, high winds, floods and snow loads on the structural integrity of light-framed constructions.
  • lateral forces generated during these natural phenomena often caused the top portion of a wall to move laterally with respect to the bottom portion of the wall, which movement could result in structural failure of the wall and, in some instances, collapse of the building.
  • Shearwalls within wall sections of light-framed constructions provide lateral stability and allow the lateral forces in the wall sections to be transmitted through the shearwalls between the upper portions of the wall and the floor diaphragm or foundation of the building where they are dissipated without structural effect on the wall or building.
  • a conventional prefabricated shearwall is anchored to an anchor bolt which extends from a foundation.
  • Anchor bolts in the foundation may also be used with hold-downs in non-prefabricated environments.
  • a concrete contractor places anchor bolts in a foundation to secure these shearwall elements. These bolts must be placed at specific locations in order to mate with the shearwall elements. If the contractor misplaces the anchor bolts, this can create a problem since it will not be recognized until the concrete sets. Since the bolts are critical to ensuring the performance of the shearwall unit, misplacement can be costly.
  • reinforcement means typically are steel reinforcing bars or rods commonly known as “rebar”.
  • the general procedure followed for forming a concrete foundation includes building wood concrete forms, inserting rebar in the form of rods running the length of the foundation or in the form of a reinforcement cage into the forms, and pouring concrete into the forms.
  • a problem faced by concrete contractors is ensuring the anchor bolts are properly positioned and their position during creation of the foundation.
  • a contractor uses a template or plastic bolt holding apparatus such as that disclosed in U.S. Pat. No. 6,065,730 attached to the concrete forms to hold the bolt in place while the concrete is poured, vibrated and set.
  • the present invention is directed to increasing the accuracy and performance of the placement of anchor bolts, mudsill anchors, or other construction connectors for wood studs or prefabricated structures, such as shearwalls, in foundations, and increasing the integrity of construction using such structures.
  • the invention comprises an anchor member securing system.
  • the securing system includes a securing bolt having a threaded region extending in a generally upward direction and a rebar cage structure secured to the bolt and having at least a first foundation placement guide.
  • anchor members such as mudsill anchors, may be utilized rather than anchor bolts. While the present invention will be shown in conjunction with providing a cage structure for anchor bolts, it will be recognized that any anchor member seated in concrete may be utilized in a cage system of the present invention.
  • the cage structure includes a top bar and a bottom bar, and the securing anchor member or bolt is attached to said top and said bottom bar.
  • the cage may include a second base bar and first and second side bars forming a rectangular base for said cage structure.
  • anchor bolts and anchor members may be used in the system in accordance with the present invention.
  • the cage structure may include at least a top bar, at least one bottom bar, a first side bar, and a second side bar, each side bar connecting the top bar and the at least one bottom bar, and said securing member is coupled to said top bar and said at least one bottom bar.
  • the cage structure may include at least a front bottom bar and a rear bottom bar, and a first base bar and a second base bar, wherein each base bar has a first end coupled to said forward bottom bar and a second end couple to said rear bottom bar, thereby forming a rectangular base.
  • any suitably shaped cage structure may be utilized with the present invention, and the invention is not limited to the particular cage structures illustrated and described herein.
  • the invention comprises an anchoring system for a shear wall.
  • the anchoring system includes at least one anchor bolt designed secure the shear wall to a foundation element and a foundation cage secured to said at least one anchor bolt.
  • the invention is an anchor system for a building.
  • the anchor system may include an anchor bolt having a threaded end and a cage, adapted for inclusion in a foundation, secured to the anchor bolt in a fixed position relative to the bolt so that the threaded end of the bolt extends above the cage, and having a foundation positioning structure.
  • the invention is a foundation support system for a building.
  • the invention includes a first anchor bolt and a second anchor bolt, each having a threaded end.
  • the foundation support system includes a cage structure having a top and bottom portions.
  • the first and second anchor bolts are secured to at least said top and bottom portions such that the threaded end of each said first and second anchor bolt extends above the top portion.
  • a positioning structure is coupled to the cage structure.
  • the invention is an apparatus, comprising a means for securing a preformed structure to a foundation, and means for positioning the means for securing in a foundation, the means for securing being attached to the means for securing.
  • the invention is a method for constructing a foundation.
  • the method includes the steps of coupling at least one anchor bolt to a rebar cage foundation support; placing the rebar cage in a position in the foundation by aligning a positioning member on the cage relative to a foundation form; and pouring concrete in the foundation form.
  • the present invention provides a unique method and apparatus to ensure that prefabricated structures attached to building foundations are securely mounted thereto, by providing anchor bolts in a secure relationship to the building foundation forms prior to the foundation pour.

  • an anchor bolt foundation system In accordance with the present invention, an anchor bolt foundation system is provided.
  • the placement of anchor bolts used to secure the structures is a fundamental element of the construction. If the bolts are improperly placed, correction involves shearing the bolt, drilling a hole in the foundation, and securing the bolt in place with epoxy. In some cases, correction may involve destroying and re-building the foundation. Increasing the structural integrity of shear walls on both the tension and compression sides of the shearwall can be achieved by increasing the use of rebar in the foundation concrete. However, engineering demands for higher hold downs and shearwall capacity has created a limitation on the concrete connection.
