The bracket further comprises a first hole in the base plate between the first U-channel and the second U-channel. While this bracket includes two U-channels, other features of the bracket may be constructed and/or utilized in the same or similar manner as described in reference to other bracket embodiments. For example, the first and second U-channels may each have a plurality of aligned holes therethrough, such as four pairs of aligned holes through each U-channel, each pair having a first hole in the first (third) upstanding plate and a second hole in the second (fourth) upstanding plate.
Some embodiments provide a structure for supporting a beam comprising a concrete footer or pier, and an anchor bolt having a first end securely embedded within the concrete footer or pier and a second end extending upward from the concrete footer or pier, wherein the second end has threads for coupling with a leveling nut and a top nut. The structure further comprises a bracket according to one of the disclosed embodiments of a bracket. For example, the bracket may comprise a base plate, and first and second upstanding plates integrally formed with the base plate and extending perpendicular to the base plate, wherein the first upstanding plate is parallel to the second upstanding plate, wherein a U-channel is formed by an inward-facing surface of the first upstanding plate, an inward-facing surface of the second upstanding plate, and an upward facing surface of the base plate, wherein the U-channel has an open top opposite the upward facing surface of the base plate and first and second open ends, and wherein the U-channel has a uniform width that is sized to receive a structural beam supported on the upward facing surface of the base plate and flush between the inward-facing surfaces of the first and second upstanding plates. The bracket may further comprise a first gusset plate formed between the base plate and an outward-facing surface of the first upstanding plate, wherein the first gusset plate is perpendicular to both the base plate and the first upstanding plate. A first hole may be disposed in the base plate outside the U-channel and adjacent the first gusset plate, wherein the second end of the anchor bolt extends through the first hole in the base plate, and wherein the leveling nut is threaded onto the second end of the anchor bolt below the base plate and the top nut is threaded onto the second end of the anchor bolt above the base plate. The structure may also comprise a block disposed between the concrete footer or pier and the base plate, wherein the block is positioned in contact with the base plate directly under the U-channel.
Footers (or “footings”) and piers are concrete structures that may be used to establish a foundation. Footers and piers are usually embedded or formed in soil to a depth that depends upon the weight of the building or other structure being supported. For example, the footer and piers for a residential home may be formed by pouring concrete into a hole that has been dug just a few feet deep. In some embodiments, a footer extends for some distance along the soil to establish a portion of a perimeter of a foundation, whereas a pier is a column that provides a point on support within the interior of the foundation.
A beam that is received in the bracket may be made from various materials using various construction techniques. One non-limiting example of a suitable beam is a laminated veneer lumber (LVL) which resists twisting, shrinking and splitting.
An anchor bolt is a special type of bolt that is used to connect another structure to concrete. Some anchor bolts are designed to be cast-in-place with an embedded end having a hexagonal head, a bend, or a welded flange. The anchor bolt also has an exposed end that extends out of the concrete and includes threads for connection with a threaded nut.
In some embodiments, the block that is disposed between the concrete footer or pier and the base plate may support substantially all of the weight of the beam and any weight placed on the beam. Accordingly, the block is preferably positioned on the top surface of the concrete footer or pier and the bracket is lowered so that the base plate rests on top of the block. By positioning the block directly under the U-channel portion of the bracket, the block will be directly under the beam and can support the weight of the beam and any weight place on the beam. The block may extend along the entire length of the U-channel and/or base plate in order to best distribute weight of the beam to the concrete footer or pier. Furthermore, the block may have a width that is as wide as the beam U-channel and/or beam in order to best distribute weight of the beam to the concrete footer or pier, and also to prevent uneven support of the beam. In fact, the block may be wider than the U-channel and/or beam so that it may be easier for a person to position the block beneath a major portion of the U-channel and/or beam.
In some embodiments, the block has a first (initial) thickness, wherein the block is replaceable with another block or combination of blocks having a total thickness that is different than the first thickness. A thickness of a block may be described as the dimension of the block that extends is the direction from the concrete structure to the base plate of the bracket. In other words, it is the thickness of the block or combination of blocks that determines the distance of separation between the top surface of the concrete structure and the bottom surface of the base plate of the bracket. A second block, such as a shim, may be stacked with the first block to support substantially all of the weight of the beam with a total thickness that is greater than the thickness of the first block alone. Alternatively, a second block have a greater or lesser thickness than the first block may replace the first block to establish a new (greater or lesser) distance of separation between the top surface of the concrete structure and the bottom surface of the base plate of the bracket
In some embodiments, structure for supporting a beam may include or utilize any of the bracket embodiments disclosed herein. For example, the structure may include a bracket having a pair of holes, including a first hole through the first upstanding plate and a second hole through the second upstanding plate, wherein the first and second holes of the pair of holes are aligned about a centerline that is perpendicular to the first and second upstanding plates. Accordingly, a bolt may extend through the first hole, through a hole in the beam and through the second hole, and the bolt may be secured with a nut. The bracket may include additional aligned pairs of holes through the first and second upstanding plates, such as four pairs of holes for receiving four bolts there through.

The blocks 15 are disposed between the base plate 82 of the bracket 80 and the footer 17 directly below each of the U-channels 87, 88 so that the weight of each beam 12, and any weight placed on the beam by the building supported on the beam 12, is supported by the footer 17 through the respective blocks 15. Except when the building is in the process of being leveled, the weight of the beams 12 and/or the building is not supported by the anchor bolts 18.
The bracket 80 may further include a gusset plate 89 that extends laterally between the second upstanding plate 84 and the third upstanding plate 85 to provide additional stability and/or rigidity to the bracket 80.
The bracket 80 may be a preferably embodiment for supported a building with a brick facade 72. Accordingly, the weight of the brick façade 72 is supported by one (outer) beam 12 and the weight of the floor 74, interior walls 76 and roof (not shown, but see
Because the blocks 15 are disposed between the bracket 80 and the footer 17 directly below the U-channels 87, 88 so that the weight of the beams 12, and any weight placed on the beams by the bricks and building supported on the beams 12, is supported by the footer 17 through the blocks 15. Except when the building is in the process of being leveled, the weight of the beams 12 and/or the bricks and building is not supported by the anchor bolts 18.

Furthermore, the method may include identifying a second bracket that supports a second beam under the identified portion of the building, wherein a second anchor bolt extends through a base plate of the identified second bracket. The method may include adjusting an elevation of the second beam supported by the identified second bracket by loosening a top nut on the second anchor bolt, turning a leveling nut on the second anchor bolt to raise the identified second bracket and the second beam supported by the identified second bracket, disposing a third block under the identified second bracket so that the identified second bracket will support the second beam at a third elevation, turning the leveling nut to lower the identified second bracket and the second beam supported by the identified second bracket, wherein the identified second bracket is lowered until the weight of the second beam is supported by the third block, and tightening the top nut on the second anchor bolt. The elevation of any of the beams in a building structure that are supported by an embodiment of the bracket may be adjusted in this manner until the building has been leveled.
