DETAILED DESCRIPTIONConcrete anchors play an important role in construction. Concrete anchors can be used to connect structures to a concrete foundation at grade or concrete floors above grade, for example, in single- and multi-story structures. Installing concrete anchors can be a time-consuming task. In some cases, the anchors are installed after the concrete has been poured, but before the concrete has set or cured. In these cases, workers will need to work quickly in order to ensure the anchors are properly positioned before the concrete sets. In other cases, concrete anchors are installed after the concrete is poured and has set. Installing anchors in these situations requires additional labor to drill holes into the concrete to position an anchor. Concrete anchors can also be installed before the concrete is poured. However, installing anchors in this manner can lead to several challenges, including ensuring the anchor remains properly positioned during the pour.
To improve the installation process, concrete anchors can be installed with a concrete anchor system. A concrete anchor system can allow for multiple anchors to be aligned and set in a foundation or concrete floor before the concrete is poured. The anchor system can utilize several features to hold an anchor rod in place while the concrete is poured and cured. Additionally, the concrete anchor system can remain in the foundation or floor, without needing to be removed. This type of anchor system can improve the concrete anchor installation process by making this process less labor intensive and more efficient.
The anchor rods 102 can be threaded and can be provided in a variety of different shapes and sizes. For example, the anchor rods 102 can have a major lateral dimension (e.g., a diameter) in a range of 0.1″ to 3″, in a range of 0.125″ to 3″, or in a range of 0.25″ to 3″. The anchor rods 102 can have any suitable length. For example, in various embodiments, the anchor rods 102 can have a length in a range of 6 inches to 10 feet, for example, in a range of 6 inches to 3 feet, in a range of 6 inches to 1.5 feet, or in a range of 1 foot to 3 feet. The anchor rods 102 may be straight rods or may have a curved end, such as a J or L rod. In some embodiments, the anchor rods 102 can comprise shear rods, which can be used to prevent the structure connected to the concrete foundation 10 from moving laterally. In various embodiments, the anchor rods 102 can comprise overturning-resisting or uplifting-resisting rods, which can be larger and/or longer than shear rods and can used to prevent the structure connected to the concrete foundation 10 from overturning. In some embodiments, anchor rods 102 of sizes and shapes that are different from those described herein can be used with the anchor rail 200. In various embodiments, the anchor rod 102 can include nuts, bolts, and washers along with the rod to secure the anchor rod 102 to the building structure. The anchor rail 200 can be positioned in several different locations within the concrete foundation 10. For example, as depicted, the anchor rail 200 can be completely embedded within the foundation 10, e.g., near the middle of the foundation 10. In some embodiments, the anchor rail 200 can be positioned near or at a bottom surface 107 of the foundation 10. In various embodiments, the anchor rail 200 can be positioned near or at a top surface 105 of the foundation 10. In some embodiments, the anchor rail 200 can be only partially embedded in the foundation 10, such that the anchor rail 200 can be about flush with the top surface 105 of the foundation 10. In various embodiments, portions of the anchor rail 200 can be exposed after the concrete foundation 10 has cured.
The concrete anchor system 100 can be installed before the concrete foundation 10 is poured. The concrete anchor system 100 can be installed by connecting the anchor rail 200 to a vertical formboard 12 or other system to hold the anchor rail 200 in place. For example, as explained herein, one or more fasteners 111 (such as nails, screws, bolts, etc.) can be inserted through corresponding fastener openings 212 in a vertical segment 206 of the rail 200 (see
The concrete anchor system 100 can be installed at any suitable location and/or depth across and within the concrete foundation 10. As depicted, the anchor rail 200 of the concrete anchor system 100 is positioned at or near the outer edge 109a of the foundation 10. In some embodiments, the anchor rail 200 can be positioned at any location within the perimeter of the foundation 10 (e.g., within the perimeter defined at least in part by outer edges 109a-109d shown in
The anchor rod holes 208, 210 can extend along at least a portion of respective lengths of the upper segment 202 and the lower segment 204. The anchor rod holes 208 formed on the upper segment 202 can be generally aligned with corresponding anchor rod holes 210 formed on the lower segment 204. In some embodiments, the anchor rod holes 208, 210 can be generally aligned and disposed at approximately the same position along a longitudinal axis x of the anchor rail 200 and along a lateral axis y perpendicular to the longitudinal axis x. In such embodiments, the anchor rods 102 can extend vertically through the holes 208, 210 and may be disposed generally perpendicular to the upper and/or lower segments 202, 204. In other embodiments, the anchor rod holes 208, 210 can be generally aligned but slightly offset along the longitudinal axis x (and/or along the lateral axis y). In such embodiments, the general or substantial alignment of the rod holes 208, 210 can enable the anchor rods 102 to be inserted therethrough, but tilted at an angle relative to the upper and/or lower segments 202, 204.
The fastener hole 212 can be formed on the upper segment 202, the lower segment 204, and/or the vertical segment 206 and can be used to connect the anchor rail 200 to other components or systems. In the illustrated embodiment, the fastener hole 212 is disposed along the vertical segment 206 and can be connected to the formboard 12 by way of one or more fasteners 111. The upper segment 202, lower segment 204, and vertical segment 206 can have a wedge 213, or rib, formed on its inner surface. The wedge 213 can increase the rigidity of upper segment 202, lower segment 204, and/or vertical segment 206. For example, in embodiments in which the rails 200 are formed of a plastic or polymer, the wedge 213 can provide improved rigidity. In other embodiments (e.g., embodiments in which the rails 200 are formed of a metal), the wedge 213 may or may not be provided.
In some embodiments, the upper segment 202 and/or lower segment can extend out of the vertical segment 206 at different locations, For example, the upper segment 202 or lower segment 204 can be extend out of the vertical segment 206 closer to the center of the vertical segment 206 and away from an end of the vertical segment 206, creating an “F” shaped cross section. In other embodiments, the anchor rail 200 does not include an upper segment 202, or the anchor rail does not include a lower segment 204, leading to an “L” or “T” shaped cross section. In some embodiments, the anchor rail 200 can include additional segments. These additional segments can be used to form an “S” shaped cross section or an “E” shaped cross section. In other embodiments, the anchor rail 200 does not include the vertical segment 206, and instead, the upper segment 202 and lower segment 204 connect to each other and form a “V” shaped cross section. Other variations of an anchor rail 200 are possible.
The anchor rail 200 can be formed from a metal, such as steel, aluminum, or any other suitable metal. In some embodiments, the anchor rail 200 can be formed from plastic. In various embodiments, the anchor rail can be formed from a variety of materials. In some embodiments, the anchor rail 200 can be formed from plastic, but can include a steel, or hardened material, covering for the corners of upper segment 202. In other embodiments, the perimeter of the upper segment, lower segment, and vertical segment can be covered with a steel, or hardened material, covering. The steel covering can prevent damage to the corners or perimeter of the anchor rail 200.
The anchor rail 200 can horizontally and/or vertically support the anchor rods 102 within the anchor rod holes 208, 210. Anchor rods 102 can be placed within the anchor rod holes 208, 210 on the opposing upper and lower segments 202, 204. The anchor rod holes 208, 210 (and the corresponding upper and lower segments 202, 204) can be spaced apart vertically along a vertical axis z. When positioned within the anchor rod holes 208, 210, the anchor rod 102 can contact the anchor rail 200 at two locations (e.g., the two opposing anchor rod holes 208, 210). Because the anchor rod 102 contacts the anchor rail 200 at two locations, the anchor rail 200 can prevent or reduce horizontal movement or rotation of the anchor rod 102 while concrete is being poured into a foundation 10, while the concrete foundation 10 cures, or during other steps of the construction process. As will be described in further detail below, the anchor rail 200 can also include vertical retention members, which prevent or reduce vertical movement of the anchor rod 102 while concrete is being poured into a foundation 10, while the concrete foundation 10 cures, or during other steps of the construction process. By preventing or reducing both horizontal and vertical movement of an anchor rod 102, an anchor rail 200 can be used to ensure the anchor rods 102 are properly positioned during the process of forming a concrete foundation 10.
The anchor rail 200 can be made into a variety of different lengths. For example, the anchor rail 200 can have a length in a range of about 6 inches to about 24 feet, in a range of about 1 foot to about 24 feet, in a range of about 2 feet to about 10 feet, or in a range of about 4 feet to about 8 feet. In some embodiments, not every anchor rod hole 208, 210 is occupied by an anchor rod 102.
As illustrated in
In some embodiments, the slotted profile 252 can be used to indicate that an anchor rod has been displaced during the installation process. For example, the upper segment 202 can use an anchor rod hole 208 with a slotted profile 252 while the lower segment utilizes an anchor rod hole 210 without a slotted profile. The anchor rod hole 210 can be aligned with the anchor rod hole 208, but not with the insertion hole boundary 251 of the hole 108. Accordingly, if an anchor rod 102 gets displaced horizontally, and transitions from the anchor hole boundary 253 to the insertion hole boundary 251 of the slotted profile 252, the anchor rod 102 will be angled. An angled anchor rod 102 can visually indicate to a worker that the anchor rod 102 has been displaced and can be readjusted before the concrete foundation 10 cures.
As illustrated in
The concrete anchor stand 500 can be used in lieu of, or in addition to, the anchor rail 200. The concrete anchor stand 500 can be used to hold a single anchor rod 102 in some embodiments. In other embodiments, more than one anchor rod can extend through a corresponding plurality of pairs of holes in the stand 500. Accordingly, in some embodiments, the concrete anchor stand 500 can have a smaller footprint than an anchor rail 200, and can thus be used in scenarios where an anchor rail 200 would not be appropriate due to the anchor rail's 200 size. The concrete anchor stand 500 can be sized such that the upper segment 502 is about flush with the top of the concrete foundation 10. The concrete anchor stand 500 can have an exposed, or partially exposed, upper segment 502 after the concrete foundation 10 cures. In some embodiments, one or more legs 506 can also be exposed along the side of the concrete foundation 10 after the concrete foundation 10 cures. The concrete anchor stand 500 can be installed at any location along the base of the concrete foundation 10. One or more concrete anchor stands 500 can be installed in a concrete foundation 10. In some embodiments, the anchor stand 500 can be completely embedded within the concrete foundation 10.
The concrete anchor system 500 can be installed before the concrete foundation 10 is poured. The concrete anchor system 500 can be installed by inserting fasteners into the fastener holes 518 to connect the concrete anchor system 500 to a horizontal formboard, vertical formboard 12, or other system. Concrete holes 516 allow for concrete to flow through and surround the entire concrete system 500. The concrete anchor system 500 can remain partially or completely embedded in the concrete foundation 10 after the concrete foundation 10 cures.
The concrete anchor system 500 can hold anchor rods 102 within the anchor rod holes 508, 510. When positioned within the anchor rod holes 508, 510, the anchor rod 102 contacts the concrete anchor system at two locations (the anchor rod holes 508, 510). Because the anchor rod 102 contacts the concrete anchor system 500 at two locations, the concrete anchor system 500 can prevent or reduce horizontal movement or rotation of the anchor rod 102 while concrete is being poured into a foundation 10 or while the concrete foundation 10 cures. The concrete foundation can also include vertical retention members, such as the rod stop 512, which can prevent or reduce vertical movement of the anchor rod 102 while concrete is being poured into a foundation 10 or while the concrete foundation 10 cures. Other vertical retention members, such as the anchor hole profiles illustrated and described in
The concrete anchor stand 500 can be formed from a metal, such as steel or aluminum. In some embodiments, the concrete anchor stand 500 can be formed from plastic. In various embodiments, the concrete anchor stand 500 can be formed from a variety of materials.

As illustrated in
In various embodiments, the flat top anchor head 600 allows the anchor rod 102 to connect to the sill plate 14 while avoiding contact with the sill plate 14. Thus, the anchor rod may not be galvanized.
In various embodiments, a mounting anchor rod 104 can be used to mount an anchor rail 200. As illustrated in
A method of using a concrete anchor assembly 100, 500 will now be described. A boundary for a concrete foundation 10 can be formed to define part or all of the footprint of the structure to be built. The boundary can be formed by placing vertical formboards 12 and horizontal formboards together. Any suitable number of anchor rails 200 and/or concrete anchor stands 500 can be installed. The anchor rail 200 can be installed by fastening the anchor rail 200 to the vertical formboard 12, horizontal formboard, or another system or component. The anchor rail 200 can be connected to these systems by utilizing a fastener hole 212 or the mounting anchor rods 104. The concrete anchor stand 500 can be installed by fastening the concrete anchor stand 500 to the vertical formboard 12, horizontal formboard, or another system or component. The concrete anchor stand 500 can be connected to these systems by utilizing a fastener hole 518. After the anchor rails 200 and/or concrete anchor stand 500 are secured, anchor rods 102 can be placed into the anchor rod holes 208, 210, 508, 510. Vertical retention members can be provided to vertically restrain the anchor rods 102. As explained herein, the vertical retention members can comprise a profile or boundary of the anchor holes 208 and/or 210. The vertical retention members can additionally or alternatively comprise a rod stop structure that physically restrains the end 101 of the anchor rod 102. Once the anchor rods 102 are secured, the concrete can be poured into the boundary for the concrete foundation 10. Once the concrete foundation 10 cures, the horizontal and/or vertical formboards 12 can be removed. The fasteners used to connect the anchor rail 200 and or concrete anchor stand 500 can optionally be removed. In some embodiments, a flat top anchor head 600 can be installed after the concrete foundation is poured and/or cured. The flat top anchor head 600 can be installed into a sill plate 14, which can be placed over the concrete foundation 10. The anchor rods 102 can be connected to a flat top anchor head 600 within the sill plate 14.
