BRACKET AND ADJUSTABLE STRUCTURES FOR LEVELING A BUILDING

Description

BACKGROUND

The present disclosure relates to a method and apparatus for leveling a building during construction or any time after construction or occupancy of the building.

BACKGROUND OF THE RELATED ART

Some buildings are constructed on a pier and beam foundation. Concrete footers and/or piers are embedded in the soil and extend upward to support a number of beams every few feet along the length of each beam. The building is then constructed on the beams which support the building above the ground. A crawl space is created under the building allowing access to the beams and other utilities run under the building. Pier and beam foundations may be used in both residential and commercial buildings. For example, a residential home may be built with a pier and beam foundation.

DETAILED DESCRIPTION

Some embodiments provide a bracket comprising a base plate, first and second upstanding plates integrally formed with the base plate and extending perpendicular to the base plate, a first gusset plate formed between the base plate and an outward-facing surface of the first upstanding plate, and a first hole in the base plate adjacent the first gusset plate, wherein the first gusset plate is perpendicular to both the base plate and the first upstanding plate, and wherein the first upstanding plate is parallel to the second upstanding plate. 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 and first and second open ends and an open top opposite the upward facing surface of the base plate, 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.

In some embodiments, the bracket may further comprise a pair of holes including a first hole through the first upstanding plate and a second hole through the second upstanding plate. The first and second holes are aligned about a centerline that is perpendicular to the first and second upstanding plates. Accordingly, with a structural beam received and supported in the U-channel, a hole may be drilled through the beam between the first and second holes. A distal end of a bolt may be inserted through the first hole, through the hole in the beam, and through the second hole, so that a nut may be threadedly connected to the distal end of the bolt. Optional embodiments may include one or more additional pair of aligned holes for further securing the bracket to the beam with a bolt and nut as described. For example, the bracket may further comprise a second 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 are aligned with a centerline that is perpendicular to the first and second upstanding plates. the second pair of holes may be vertically spaced apart from the first pair of holes, horizontally space apart from the first pair of holes, or both vertically and horizontally spaced apart from the first pair of holes. In some embodiments, the bracket will have four pairs of aligned holes, each pair having a first hole in the first upstanding plate and a second hole in the second upstanding plate.

The first hole in the base plate is sized to receive a shank of an anchor bolt therethrough. The anchor bolt has a first end securely embedded within a concrete structure and a second end extending upward from the concrete structure, wherein the second end has external threads for coupling with a leveling nut and a top nut. The shank of the anchor bolt that is received through the first hole is threaded to threadedly couple with the leveling nut below the base plate of the bracket and threadedly couple with the top nut above the base plate of the bracket. Optionally, the base plate may include additional holes sized to receive a shank from an additional anchor bolt therethrough.

In some embodiments, the bracket may comprise a second gusset plate formed between the base plate and an outward-facing surface of the second upstanding plate, wherein the second gusset plate is perpendicular to both the base plate and the second upstanding plate. A second hole may then be included in the base plate outside the U-channel and adjacent the second gusset plate. The first and second holes in the base plate are each sized to receive a shank of an anchor bolt therethrough. The first and second gusset plates add strength to the bracket and may prevent the first and second upstanding plates from bending or deflecting. Optionally, one or both of the gusset plates may extend from a lateral edge of the base plate to an upper edge of the respective upstanding plate. However, smaller gusset plates may also be used. In a further option, the base plate may include one or more additional hole adjacent the first gusset plate and one or more additional hole adjacent the second gusset plate, where each additional hole is sized to receive a shank from an additional anchor bolt therethrough. In a specific example, a base plate may include first and second holes on opposite sides of the first gusset and first and second holes on opposite sides of the second gusset.

The bracket may be made from various materials. Without limitation, the bracket may be made from a metal or a high-strength composite. The metal may be a metal alloy, such as steel (an alloy of iron and carbon) or an alloy steel (an alloy including steel in combination with another alloyant, such as manganese, nickel, chromium, molybdenum, vanadium, silicon, boron, aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead and/or zirconium). The high-strength composite may be a polymer matrix composite that includes fibers bound together by an organic polymer matrix. The polymer matrix may be either a thermoplastic polymer or a thermoset polymer, such as an epoxy, phenolic, polyurethane and/or polyimide. Optional fibers may include carbon nanotubes or graphene. The bracket is preferably a single integral piece made of the same material, such as by welding, casting or extrusion.

Some embodiments provide a bracket comprising a base plate, first and second upstanding plates integrally formed with the base plate and extending perpendicular to the base plate, as well as third and fourth upstanding plates integrally formed with the base plate and extending perpendicular to the base plate. The first upstanding plate is parallel to the second upstanding plate, wherein a first 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 first U-channel has first and second open ends and an open top opposite the upward facing surface of the base plate, and wherein the first U-channel has a uniform width that is sized to receive a first 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 third upstanding plate is parallel to the fourth upstanding plate, wherein a second U-channel is formed by an inward-facing surface of the third upstanding plate, an inward-facing surface of the fourth upstanding plate, and the upward facing surface of the base plate, wherein the second U-channel has an open top opposite the upward facing surface of the base plate and first and second open ends, and wherein the second U-channel has a uniform width that is sized to receive a second structural beam supported on the upward facing surface of the base plate and flush between the inward-facing surfaces of the third and fourth upstanding plates. 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.

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.

In some embodiments, the method may further comprise 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.

FIG. 1 is a perspective assembly view of an adjustable structure 10 for supporting a beam 12 above an external footer 14 for a building. The footer 14 is embedded in the soil 16 to form a solid foundation upon which to support the building. First and second anchor bolts 18 have a first end 20 securely embedded within the concrete footer 14 and a second end 22 extending upward from the concrete footer 14, wherein the second end 22 has threads for coupling with a leveling nut 24 and a top nut 26.

A bracket 30 includes a base plate 32, a first upstanding plate 34 and a second upstanding plate 36, where both of the upstanding plates 34, 36 are integrally formed with the base plate 32 and extend perpendicular to the base plate. Furthermore, the first upstanding plate 34 is parallel to the second upstanding plate 36. A U-channel 38 is thus formed by an inward-facing surface of the first upstanding plate 34, an inward-facing surface of the second upstanding plate 36, and an upward facing surface of the base plate 32. The U-channel 38 has an open top opposite the upward facing surface of the base plate and first and second open ends. The U-channel 38 also has a uniform width (i.e., uniform distance between the plates 34, 36) that is sized to receive the beam 12 supported on the upward facing surface of the base plate 32 and flush between the inward-facing surfaces of the first and second upstanding plates 34, 36. The bracket 30 may further comprise a first gusset plate 40 formed between the base plate 32 and an outward-facing surface of the first upstanding plate assembly 34, wherein the first gusset plate 40 is perpendicular to both the base plate 32 and the first upstanding plate 34.

A first hole 42 may be disposed in the base plate 32 outside the U-channel 38 and adjacent the first gusset plate 40. The leveling nut 24 is threaded onto the second end 22 of the anchor bolt 18 below the base plate 32, the threaded second end 22 of the anchor bolt 18 extends through the first hole 42 in the base plate 32, and the top nut 26 is then threaded onto the second end 22 of the anchor bolt 18 above the base plate 32. The structure 10 may also comprise a block 15 disposed between the concrete footer 14 and the base plate 32 and positioned in contact with the base plate 32 directly under the U-channel 38. A similar second hole 42 is shown on the other side of the gusset plate 40 and is used in the same manner as the first hole 42 for receiving a second end 22 of a second anchor bolt 18.

The bracket 30 further includes a pair of holes including a first hole 44A through the first upstanding plate 34 and a second hole 44B through the second upstanding plate 36. The first and second holes 44A, 44B are aligned about a centerline 44C that is perpendicular to the first and second upstanding plates 34, 36. Accordingly, with a structural beam 12 received and supported in the U-channel 38, a hole 44D (shown in dashed lines) may be drilled through the beam 12 between the first and second holes 44A, 44B. A distal end of a bolt 46 may be inserted through the first hole 44A, through the hole in the beam 44D, and through the second hole 44B, so that a nut 48 may be threadedly connected to the distal end of the bolt 46. As shown, three additional pairs of aligned holes are spaced apart from the first pair of holes 44A, 44B for further securing the bracket 30 to the beam 12 with a three additional bolts and nuts as described.

FIG. 2 is a perspective assembly view of an adjustable structure 50 for supporting a beam 12 above an internal pier 13 for a building. In reference to FIG. 2, individual components that are similar to those of FIG. 1 may be described with the same reference numbers.

A bracket 60 includes a base plate 62 that is wider than the base plate 32 of bracket 30 in FIG. 1. However, the bracket 60 still include a first upstanding plate 34 and a second upstanding plate 36, where both of the upstanding plates 34, 36 are integrally formed with the base plate 62 and extend perpendicular to the base plate. Furthermore, the first upstanding plate 34 is parallel to the second upstanding plate 36. A U-channel 38 is thus formed by an inward-facing surface of the first upstanding plate 34, an inward-facing surface of the second upstanding plate 36, and an upward facing surface of the base plate 62. The U-channel 38 has an open top opposite the upward facing surface of the base plate and first and second open ends. The U-channel 38 also has a uniform width (i.e., uniform distance between the plates 34, 36) that is sized to receive the beam 12 supported on the upward facing surface of the base plate 62 and flush between the inward-facing surfaces of the first and second upstanding plates 34, 36.

The bracket 60 may further comprise a first gusset plate 40 formed between the base plate 62 and an outward-facing surface of the first upstanding plate assembly 34, wherein the first gusset plate 40 is perpendicular to both the base plate 32 and the first upstanding plate 34. Furthermore, the bracket 60 may further comprise a second gusset plate (not shown) that formed between the base plate 62 and an outward-facing surface of the second upstanding plate assembly 36, wherein the second gusset plate is perpendicular to both the base plate 62 and the first upstanding plate 36. The second gusset plate may be constructed the same as the first gusset plate, such as where the bracket 60 is symmetrical on either side of the U-channel 38 (see also FIGS. 7A and 7B).

The bracket 60 has four holes 42 disposed in the base plate 62 (only three of the four holes 42 are shown) outside the U-channel 38, with two holes 42 adjacent the first gusset plate 40 and two holes 42 adjacent the second gusset plate (not shown; but see also FIGS. 7A and 7B). A leveling nut 24 is threaded onto the second end 22 of each of four anchor bolts 18 below the base plate 62 (only three leveling nuts 24 are shown), the threaded second end 22 of each anchor bolt 18 extends through a respective one of the four holes 42 in the base plate 62, and a top nut 26 is then threaded onto each of the second ends 22 of the four anchor bolts 18 above the base plate 62 (only two top nuts 26 are shown). The structure 10 may also comprise a block 15 disposed between a top surface of the concrete pier 13 and the bottom surface of the base plate 62 and positioned for contact with the base plate 62 directly under the U-channel 38. To the extent that any component of the adjustable structure 50 is not shown, the structure 50 of FIG. 2 may be considered to be symmetrical such that the front view shown in FIG. 2 is representative of a back view.

As with the bracket 30 of FIG. 1, the bracket 60 of FIG. 2 further includes a pair of holes including a first hole 44A through the first upstanding plate 34 and a second hole 44B through the second upstanding plate 36. The first and second holes 44A, 44B are aligned about a centerline 44C that is perpendicular to the first and second upstanding plates 34, 36. Accordingly, with a structural beam 12 received and supported in the U-channel 38, a hole 44D (shown in dashed lines) may be drilled through the beam 12 between the first and second holes 44A, 44B. A distal end of a bolt 46 may be inserted through the first hole 44A, through the hole in the beam 44D, and through the second hole 44B, so that a nut 48 may be threadedly connected to the distal end of the bolt 46. As shown, an additional three pairs of aligned holes are spaced apart from the first pair of holes 44A, 44B and there are three additional holes 44D in the beam for further securing the bracket 30 to the beam 12 with a three additional bolts and nuts as described.

FIG. 3 is a side view of the adjustable structure 10 for supporting a beam 12 above the external footer 14 for a building in a manner consistent with FIG. 1 and the adjustable structure 50 for supporting another beam 12 above an internal pier 13 for the building (only partially shown above the beams 12) in a manner consistent with FIG. 2. However, compared with the perspective assembly views of FIGS. 1 and 2, the adjustable structures 10 and 50 have been fully assembled. Accordingly, the anchor bolts 18 have a leveling nut 24 secured under each of the base plates 32, 62 and a top nut 26 secured over each of the base plates 32, 62 with each of the base plates 32, 62 sitting on the blocks 15.

A beam 12 is received within the U-channels 38 of each bracket 30, 60 and is secured within the U-channels 38 with bolts 46 and nuts 48. The blocks 15 are disposed between the brackets 30, 60 and the footer 14 or pier 13 directly below the U-channels 38 so that the weight of the beams 12, and any weight placed on the beams by the building supported on the beams 12, is supported by the footer 14 or pier 13 through the 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.

FIG. 4 is a perspective assembly view of an adjustable structure 70 for supporting a pair of beams 12 above an external footer 17 for a building. In reference to FIGS. 2 and 3, individual components that are similar to those of FIGS. 2 and 3 may be described with the same reference numbers.

FIGS. 9A to 9F provide a sequence of diagrams illustrating steps of installing a bracket 60 of an adjustable structure 50 for supporting a beam (not shown). It should be recognized that although the number of anchor bolts 18 and the number of holes 42 vary from one bracket embodiment to another, and hence also the number of leveling nuts 24 and top nuts 26 also varies from one bracket embodiment to another, the basic steps of installing a bracket are essentially the same regardless of which bracket embodiment is being used.

In FIG. 9A, the concrete pier 13 has been formed with the anchor bolts 18 having a first end 20 embedded in the concrete and a threaded second end 22 extending upward from the top surface of the pier 13. Note the curved tip on the embedded first end 20 that may help support the anchor bolt and/or to prevent turning of the anchor bolt 18 when a nut is threaded onto or along the anchor bolt.

In FIG. 9B, a leveling nut 24 is threaded onto the threaded second end 22 of each anchor bolt 18. In addition, a block 15 has been placed on the top surface of the pier 13 between the two anchor bolts 18.

In FIG. 9C, the bracket 60 has been positioned to rest on the block 15 with the threaded second end 22 of the anchor bolt 18 received through holes 42 in the base plate 62 of the bracket 60. The first and second upstanding plates 34, 36, along with the upward facing surface of the base plate 62 for a U-channel 38.

In FIG. 9D, the beam 12 has been received through the open top of the U-channel 38, such that the beam 12 rests against the base plate 62 which rests on the block 15. As a result, the weight of the beam 12 is supported by the pier 13 through the block 15. Each beam 12 in a building structure may be supported by one or more brackets 60 along the length of the beam. So, if the beam 12 is not level prior to constructing the building on the beam, the beam 12 may be leveled by lifting the beam and replacing the block 15 with another block having a different thickness. If the beam is not easily lifted by hand, then the leveling nuts may be used to raise the beam to facilitate replacement of the block 15. This can be repeated any number of times, until the beam is level. In fact, a block associated with any of the brackets supporting any of the beams in a building structure may be replaced or supplemented with shims or other materials until the entire beam structure for supporting a building is level.

In FIG. 9E, the leveling nuts 24 may be raised, if desired, to simply prevent the bracket from rocking from side to side without actually supporting any weight of the beam. Then, the top nuts 26 are tightened down onto the base plate 62 to hold the bracket 60 down against the block 15. At this point, holes 44D may be drilled through the beam 12 by running a drill bit between the aligned holes 44A, 44B. In the embodiments shown, each U-channel has four pair of aligned holes such that the beam may be drilled to form four holes in the beam. Accordingly, four bolts may be extended there through and secured with a nut.

In FIG. 9F, the bolts 46 are run through the aligned holes 44A, 44B and the hole 44D through the beam 12. The nut 48 is then tightened down to secure the beam 12 to the bracket 60. When each beam of the building structure has been leveled and secured in this manner, the remainder of the building structure may be constructed on the beams.

FIGS. 10A to 10F provide a sequence of diagrams illustrating steps of adjusting the elevation of a beam, which may be included in a method of leveling a building. It should be understood that the beams 12 shown in FIGS. 10A to 10F may already support a finished building with additional contents within the building. Accordingly, the weight of the beams 12 may be relatively minor in relation to the weight of the building and building contents that is being supported by the beams 12. Therefore, adjusting the elevation of a beam 12 using one of the adjustable structures 10, 50, 70 of FIGS. 1, 2, 4 requires raising or lifting the weight of the beam 12 and all of the weight being supported by the beam 12. Furthermore, it should be understood that the crawlspace under a building of this type enables a person to gain access to the adjustable structures, but would prevent access by forklifts, backhoes and other heavy equipment.

In FIG. 10A, the beam 12 is supported as described in reference to FIG. 9F. However, as part of a method for leveling a building, assume that the beam 12 has been identified as being located in a portion of a building that requires a change of elevation to achieve a level condition, and that bracket 60 is secured to the identified beam 12 or portion of the beam under the identified portion of the building.

In FIG. 10B, the top nuts 26 are raised (by turning) to disengage the base plate 62. In FIG. 10C, the leveling nuts 24 having been raised (by turning) to lift the beam 12 off the block 15. Note that the leveling nuts 24 may be accessed from the side with an open end wrench (not shown).

In FIG. 10D, the block 15 (from FIG. 10C) has been replaced with a second new/different block 19 having different thickness than the first block 15. Note that the beam 12 and bracket 60 must be raised to take pressure off the block 15 for removal even if the new/different block 19 has a thickness that is less than the thickness of block 15. So, the thickness of the new/different block 19 is selected in order provide a desired amount of increase or decrease in elevation of the beam 12 at the location of the pier 13. It should be understood that the change in elevation of the beam is the direct result of the change in thickness between the previous block 15 and the new/different block 19. Furthermore, the change in elevation and/or the change in thickness may be accomplished either by replacing the block 15 or by adding or removing shims in a stack with block 15. Therefore, while the blocks 15, 19 are shown as single blocks, they may be considered to represent any one or more combination of blocks. Each block may be made with wood, metal or a composite material.

In FIG. 10E, the leveling nuts 24 are lowered (by turning) so that the weight of the beam 12 and any weight supported by the beam 12 rests against the new/different block 19. In FIG. 10F, the top nuts 26 are lowered (by turning) until the top nuts 26 are tightened down against the base plate 62. The beam is now supported at a second elevation that may be greater than the first elevation or less than the first elevation depending upon the thickness of the second block or blocks relative to the thickness of the first block or blocks. Embodiments of the method of leveling a building may include or utilize any one or more aspect of the disclosed embodiments of a structure for supporting a beam and/or any one or more aspect of the disclose embodiments of a bracket.

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.

FIG. 11A is a plan view of a plurality of adjustable structures 10, 50 supporting beams 12 for a building. A greater or lesser number of beams 12 may be used in this or any other configuration to support a desired building. Furthermore, if a method of leveling a building identified that the portion 90 of the building has sagged and was no longer level, the three adjustable structures 10 in the identified portion 90 could be adjusted as described in reference to FIGS. 10A to 10F until that portion of the building was level with the rest of the building. Any one or more of the adjustable structures 10, 50 may be adjusted upward and/or downward in elevation by any variable amount as necessary to level the building.

FIG. 11B is a cross-sectional side view of a building 92 supported on the beams 12 of FIG. 11A as viewed along line A-A. Collectively, the beams 12 may support a floor 94, walls 96 and a roof 98, as well as any contents of the building 92.
