TECHNICAL FIELD
The present disclosure relates generally to modular support systems, including those configured to provide load-bearing support to multi-story buildings.
BACKGROUND
The present disclosure relates generally to modular support systems for multi-story buildings. In particular, modular support systems that include a plurality of load-bearing structural units are described.
Known building support systems are not entirely satisfactory for the range of applications in which they are employed. Many buildings, for example, implement a concrete column-based support structure. Constructing buildings with concrete column-based support structures is inefficient. For example, constructing a building with a concrete column-based support system may require builders to iteratively pour the concrete structural elements of each floor individually.
In such a process, all of the structural work on a floor must be completed before any structural work can begin on a vertically adjacent floor. This iterative process often bottlenecks construction projects and delays progress.
Further, concrete column-based construction requires a large amount of work to be performed by on-site laborers. The large amount of on-site labor further increases costs and creates scheduling difficulties.
Constructing buildings with structural steel-based support systems are another conventional construction method, but structural steel-based methods do not adequately address many of the shortcomings of concrete-based methods. For example, structural steel drastically reduces the amount of concrete to be poured during construction. This decrease in labor, however, is offset by the need to individually weld a large number of structural steel elements. Indeed, structural steel supports often require builders to iteratively and labor-intensively construct each floor on site. Accordingly, conventional structural steel systems are often as labor intensive, expensive, and slow as conventional concrete-based projects.
Further, many buildings constructed with conventional structural steel-based support systems include irregular floor plans that require a variety of structural members to be used over the course of construction. At some times during production, stocks may be depleted due to one or more of delayed deliveries, depleted stocks, errors in ordering, or other causes of depleted supplies. Such shortfalls in supply may result in delays and additional labor costs.
Wood-based support systems address some of the shortcomings of conventional structural steel and concrete based support systems. For example, labor costs associated with some wood supported projects are dramatically reduced compared to structural steel and concrete supported projects. Further, wood-based support systems may, in some examples, be quicker and less labor-intensive to construct.
Many wood-based support systems, however are unable to adequately support multi-story buildings, particularly those that include more than two floors. Accordingly, wood-based support systems are only adequate for very small-scale construction projects and are inadequate for larger-scale projects including 3 or more floors. As a result, wood-based support systems are inadequate for larger-scale, multi-story applications. As a result, there exists a need for support systems that take advantage of the lower cost provided by wood-based support systems while supporting the multi-story structures that currently require steel or concrete-based support systems.
Thus, there exists a need for support systems that improve upon and advance the design of known support systems. In particular, there exists a need for support systems that are adequate to support larger-scale multi-floor projects that require less on-site labor than conventional concrete and/or structural steel-based projects. Examples of new and useful modular support systems relevant to these and other needs existing in the field are discussed below.
SUMMARY
The present disclosure is directed to modular support systems for supporting multi-story buildings including plates having bottom major faces and top major faces, the plates defining bolt holes extending through the plates, vertical columns extending from bottom ends to top ends opposite the bottom ends, the bottom ends of the vertical columns being welded to the top major faces of the plates, and horizontal columns having bottom sides and top sides opposite the bottom sides, the bottom sides of the horizontal columns being welded to the top end of the vertical columns. In some examples, the horizontal column defines bolt holes being positioned to align with the bolt holes defined in the plate. Some examples include pluralities of structural units selectively fastened together in a vertical arrangement, with each structural unit configured to selectively couple with a vertically adjacent structural unit. Some examples define buildings including the disclosed support systems.

With reference to FIGS. 1-8, a first example of a modular support system, system 100, will now be described. As FIG. 1 illustrates, system 100 includes a plurality of structural units arranged to define a building support structure. For example, system 100 includes, among other structural units, a first structural unit 110i, a second structural unit 110ii, a third structural unit 110iii, and a fourth structural unit 110iv. 
System 100 provides a structural steel-based support system configured to support a multi-story building. System 100 is configured to support at least a minimum load-bearing capacity of the building, the minimum load-bearing capacity being selected to support the structural elements and the expected contents of the building. Further, system 100 provides a modular structure constructed of parts that may be largely fabricated off-site at a production facility before being installed at a construction site.
Additionally, system 100 includes a substantially identical set of pre-fabricated structural units, thereby drastically reducing the number of unique parts that are required to be stocked and installed on-site during construction. System 100 further supports a method of installing the pre-fabricated structural units without welding at the construction site, which may reduce or eliminate the need for on-site welders.
As a result, system 100 provides a structural steel-based support system with efficiency gains through pre-fabrication and a simpler, weld-free install process. Further, by shifting a significant amount of the labor to off-site pre-fabrication, system 100 dramatically reduces on-site build times. Through these efficiency gains, system 100 allows construction of multi-story buildings at prices and build times that are dramatically lower than would be associated with conventional structural steel-based construction methods. Indeed, the disclosed systems allow multi-story structural steel-based projects to be constructed at times and costs typically associated with projects with wood-based structural supports.
As FIG. 1 illustrates, each of the structural units of system 100 includes substantially the same basic components. First structural unit 110i, for example, includes a plate 112i, a plurality of vertical columns 116i, and a horizontal column 125i. While some structural units may define different lengths, heights, and/or a different number of vertical columns, each structural unit is constructed of these basic components.
This disclosure notes, however, that all structural units that are horizontally aligned and vertically coupled with one another (e.g., those that are positioned on the same portion of the floor plan in each floor) are substantially identical. As a result, each floor utilizes substantially identical components for installation as every other floor in the building. This uniformity in construction assists supply management and parallel construction, as structural units and other parts available on-site may often be used at multiple parts of system 100.
As FIG. 1 shows, second structural unit 110ii is horizontally spaced from first structural unit 110i by a predetermined room width distance. This allows first structural unit 110i and second structural unit 110ii to support, between them, a housing unit with a width of the predetermined room width. Aside from the different position, second structural unit 110ii is otherwise substantially identical to first structural unit 110i, and includes the same core components. Further, because they are on the same floor, first structural unit 110i and second structural unit 110ii both define a height of a predetermined floor height.
Likewise, third structural unit 110iii, which is vertically-coupled to first structural unit 110i, is substantially identical to first structural unit 110i. Similarly, fourth structural unit 110iv is vertically coupled to second structural unit 110ii, and is also substantially identical to second structural unit 110ii. As FIG. 1 illustrates, third structural unit 110iii and fourth structural unit 110iv are each substantially identical to both first structural unit 110i and second structural unit 110ii. 
Although third structural unit 110iii and fourth structural unit 110iv are the same height as the other illustrated structural units, this disclosure contemplates that structural units on different floors may define different heights as long as the height of structural units on the same floor all define a consistent height.
FIG. 2 illustrates an example floor plan that may be constructed using system 100. As FIG. 1 shows, system 100 favors a construction wherein vertically coupled structural units are uniformly stacked upon one another through the entire height of an associated building. Because of this modular design, the placement of the structural units shown in the floor plan in FIG. 2 will be repeated on every floor in the building shown in FIG. 2. As will be discussed in more detail below, designers may be afforded a good amount of freedom in adjusting the housing unit layout of each floor by routing passageways through the structural units, particularly between vertical columns, and by strategically placing non-load bearing walls throughout the floor.
As FIG. 2 shows, each structural unit extends at a predetermined structural unit length, meaning, by extension, that the plate and horizontal unit extend at equal lengths equal to the predetermined structural unit length associated with the structural unit. Vertically stacked structural units, in many examples, each have a uniform predetermined structural unit length. In some examples, the predetermined structural unit length may be uniform amongst all structural units in a building. In other examples, the predetermined structural unit length may be uniform against all or a majority of all structural units in a section. Other examples may include structural units widely disparate structural unit lengths amongst structural units on the same floor, such as the example shown in FIG. 2.
As FIG. 2 illustrates, the structural units of system 100 are separated into a plurality of distinct sections, including a first section 94, a second section 96, a third section 97, and a fourth section 99. As FIG. 2 shows, each section includes a group of parallel, aligned structural units.
As FIG. 2 shows, structural unit sections may be oriented in a variety of different directions in the same building. For example, the structural units in first section 94 and second section 96 are parallel to one another, whereas third section 97 and fourth section 99 are perpendicular to first section 94 and second section 96, but parallel to one another. Including multiple distinct structural unit sections oriented a variety of ways provides great flexibility in building shape and design while maintaining the module structure of system 100.
As FIG. 2 shows, first section 94 and second section 96 are spaced from one another to define a corridor 95 between them. Similarly, third section 97 and fourth section 99 are similarly spaced to define a corridor 98, which is similarly sized and connected to corridor 95. Corridor 95 and corridor 98 may allow people to move through the building to navigate between the housing units defined by the structural units.
While corridor 95 and corridor 98 are routed through spaces between structural unit sections, this is not specifically required. In fact some examples may lack distinct structural unit sections altogether. Indeed, structural units may, in some examples, be installed over the entire area of a building's floor plan and thereby essentially define only a single section of structural units. In such an example, the entire floor plan of the associated building may be defined by a single row of parallel structural units.
In examples lacking space between structural unit sections, corridors may be routed between the vertical columns of a floor's structural units. Indeed, by strategically placing non-load bearing walls, carefully routing corridors between vertical columns, and selectively placing walls and/or passageways between vertical columns of structural units, buildings with single structural unit sections may afford even greater flexibility in floor plan design than those with multiple sections.
FIG. 3 illustrates a portion of both first structural unit 110i and third structural unit 110iii exploded to show the individual components of each structural unit. As FIG. 3 shows, first structural unit 110i includes plate 112i, vertical columns 116i, and horizontal column 125i. FIG. 3 illustrates two illustrative vertical columns 116i: a first vertical column 117i and a second vertical column 119i. 
First structural unit 110i, as displayed in FIGS. 3 and 4, represents the most basic building block of system 100. As FIG. 1 shows, structural units will, in most cases, include at least two vertical columns extending between the structural unit's plate and horizontal bar, though they may include significantly more than two. Vertical columns are often spaced along the length of structural units by a predetermined column spacing distance. The predetermined column spacing distance is often calculated based on the expected necessary load capacity of the modular support system and the minimum distance required to allow passage between the vertical columns.
The number of columns on a particular structural unit is typically the maximum amount of columns that will fit along the length of the structural unit when spaced the predetermined column spacing distance. Some structural units, may additionally include an additional column at one or both end that is spaced from the adjacent column by less than the predetermined column spacing distance.
As FIG. 1 shows, plate 112i extends horizontally along the length of first structural unit 110i. Plate 112i is welded to the bottom of each vertical column 116i. To avoid redundancy, this disclosure focuses on plate 112i specifically to describe the disclosed plates generally. As FIG. 1 shows, each structural unit includes a plate substantially similar to plate 112i. Unless this disclosure discusses specific differences between plate 112i and other plates, the reader should reference the discussion of plate 112i for details of the other plates.
As FIG. 3 shows, plate 112i defines a top major face 113i, a bottom major face 114i, and a plurality of plate bolt holes 115i. As FIG. 4 shows, top major face 113i, when plate 112i is connected to vertical columns 116i, extends horizontally along the bottom end of each paired vertical column.
Plate 112i does not necessarily bear any load, but rather acts as an interface allowing first structural unit 110i to be coupled with a vertically adjacent structural unit below first structural unit 110i. Specifically, as FIG. 3 shows, plate bolt holes 115i may be positioned to be aligned with bolt holes in the horizontal column of a paired structural unit. By aligning the bolt holes in this manner, plate 112i may allow the vertically adjacent structural units to be coupled with one another by using a fastener, rather than welding. This may reduce on-site welding costs while simplifying the installation process.
As FIG. 1 illustrates, vertical columns 116i are welded to plate 112i. FIG. 3 shows an example portion of first structural unit 110i, specifically illustrating first vertical column 117i and second vertical column 119i in greater detail. As FIG. 1 shows, vertical columns 116i include a plurality of vertical columns that are positioned to be substantially equally spaced from one another across the entire length of first structural unit 110i. 
As FIG. 2 shows, various structural units used in a particular design may extend at different lengths from one another. The number of vertical columns included in such structural units may be adjusted proportionately to such differences in length.
Each vertical column on a particular floor is often identical, which may increase the uniformity of the materials of system 100. Further, the vertical columns of each structural unit are often welded to the associated plate during an off-site pre-fabrication process. This may reduce on-site work and result in a cheaper, more efficient build process.
To avoid redundancy, this disclosure focuses on first vertical column 117i specifically to describe disclosed vertical columns generally. As FIG. 1 shows, each structural unit includes vertical columns substantially similar to first vertical column 117i. Unless this disclosure discusses specific differences between first vertical column 117i and other vertical columns, the reader should reference the discussion of first vertical column 117i for details of the other vertical columns.
As FIG. 3 shows, first vertical column 117i extends at a length selected to size first structural unit 110i at a predetermined floor height, in some examples, first vertical column 117i may be the same height as vertical columns on all of the other floors of system 100. In other examples, however, vertical columns on other floors may define heights different from first vertical column 117i. 
Although all vertical columns 116i extend substantially straight vertically and perpendicularly to plate 112i, this is not specifically required. Some examples may include one or more vertical columns that extend from plate 112i toward horizontal column 125i at an angle other than 90 degrees. Additionally or alternatively, one or more supplemental vertical supports may extend between plate 112i and horizontal column 125i at an angle other than 90 degrees.
As FIG. 3 illustrates, first vertical column 117i defines a wide structural steel beam defining a first side flange, a second side flange spaced from the first side flange, and a web extending between the side flanges. First vertical column 117i defines a gauge selected to provide a portion of the load-bearing support to a building supported by system 100. First vertical column 117i is commonly referred to as a w-beam or i-beam. This particular beam shape and construction material is not specifically required, however.
Structural units on the upper floors of a building are required support a lessened portion of the building's expected minimum load-bearing capacity than those on lower floors. Accordingly, the layout of upper floors may have adjusted layouts that remove one or more structural units to accommodate larger rooms or housing units.
In some examples, vertical columns on different floors or at different horizontal positions may define different gauges. For example, columns on lower floors may define larger gauges to accommodate the larger share of load-bearing support that lower floors must provide.
As FIG. 1 illustrates, horizontal column 125i extends horizontally substantially parallel to plate 112i and is welded to the top of vertical columns 116i. To avoid redundancy, this disclosure focuses on horizontal column 125i specifically to discuss the features of disclosed horizontal columns generally. As FIG. 1 shows, each structural unit includes a horizontal column substantially similar to horizontal column 125i. Unless this disclosure discusses specific differences between horizontal column 125i and other horizontal columns, the reader should reference the discussion of horizontal column 125i for details of the other horizontal columns.
As FIG. 1 shows, horizontal column 125i is substantially equal in length to plate 112i. FIG. 3 discloses a portion of horizontal column 125i in greater detail. As FIG. 3 shows, horizontal column 125i defines a structural steel wide-flange beam with a top flange defining a top side, a bottom flange defining a bottom side, and a web extending between the top flange and the bottom flange.
As FIG. 1 shows, horizontal column 125i is welded to each vertical column 116i. In some examples, horizontal column 125i is welded to vertical columns 116i in an off-site pre-fabrication process. By performing these welds off-site, the on-site construction workload may be reduced and a more efficient build process may result. Indeed, because horizontal column 125i, vertical columns 116i, and plate 112i are all able to be welded to one another off-site, first structural unit 110i, along with all of the other structural units, is specifically configure to be prefabricated off-site and delivered to a construction site. Once on site, the structural units may be installed and coupled with one another without additional on-site welding, resulting in a low-cost, simple install process.
As FIG. 3 illustrates, horizontal column 125i defines a plurality of horizontal beam bolt holes 127i extending through the top flange. As FIG. 3 shows, horizontal beam bolt holes 127i are horizontally aligned with plate bolt holes 115i. 
Because the horizontal bolt holes and plate bolt holes of structural units are aligned with one another, structural units are configured to be stacked on one another. In particular, the structural units are configured to be stacked with the horizontal beam and plate bolt holes aligned with one another as plates are engaged with horizontal beams of adjacent structural units. More precisely, the plate holes of an upper structural unit may be aligned with and proximate to the horizontal beam holes of a lower structural unit when the upper structural unit is stacked on the lower structural unit.
FIGS. 3 and 4 illustrate a portion of second structural unit 110ii in addition to first structural unit 110i. As FIGS. 3-5 show, second structural unit 110ii is configured to couple to first structural unit 110i using a fastener. FIG. 6 illustrates a close up view showing additional details of an example attachment point between first structural unit 110i and second structural unit 110ii. As FIG. 3 shows, second structural unit 110ii includes a plurality of plate bolt holes 115ii that are positioned to align with horizontal beam bolt holes 127i. 
As FIG. 3 illustrates, system 100 includes a plurality of fasteners 150 configured to be routed through the aligned plate bolt holes 115ii and horizontal beam bolt holes 127i. As FIG. 6 shows, fasteners 150 may be routed through plate bolt holes 115ii and horizontal beam bolt holes 127i. When so routed, fasteners 150 extend through the aligned bolt holes to selectively couple first structural unit 110i to second structural unit 110ii. 
As FIG. 3 shows, fasteners 150 each specifically define a bolt 151, a washer 152, and a nut 153. As FIG. 4 shows, second structural unit 110ii may be coupled to first structural unit 110i by routing bolt 151 through plate bolt holes 115ii and horizontal beam bolt holes 127i with a wide portion side of bolt 151 proximate first structural unit 110i and a threaded portion on a side of bolt 151 proximate second structural unit 110ii, slidingly receiving washer 152 on the threaded portion, and screwingly receiving nut 153 on the threaded portion.
As shown in FIG. 4, coupling second structural unit 110ii to first structural unit 110i using fasteners 150 allows second structural unit 110ii to be non-weldingly coupled to first structural unit 110i. 
Because of the bolt-based structural unit coupling methodology described above, the pre-fabricated structural units may be coupled to one another on-site without any welding. As a result, system 100 may be constructed at a construction site without performing any on-site welding. In fact, the bolt-based installation method may be relatively easy to attach without any substantial, heavy equipment.
Reducing the need for on-site welding to couple structural units from one another provides a myriad of benefits. For example, on-site welding is one of the most significant costs of constructing many conventional steel-based support systems; by reducing the amount of welding required, system 100 may drastically lower total construction costs. Additionally or alternatively, the bolt-based coupling methodology may be quicker and easier to perform than on-site welds.
When structurally units are installed and coupled, each structural unit may optionally support removable, non-load bearing walls that extend along structural units between adjacent vertical columns. This may afford designers and constructors great flexibility in laying out floor plans for housing units. In some portions of a constructed building, walls may extend along the entire length of a pair of horizontally adjacent structural units. In such portions, housing units may consist of only the space between horizontally adjacent structural units.
In other portions, however, one or more structural units may define doors or voids between some vertical columns. By defining a void or doorway between vertical columns, designers may be able to allow passage through the structural unit. This may allow for housing units that span across multiple structural units.
Further, non-structural walls or doorways may extend across a pair of horizontally adjacent structural units. Such non-structural walls may be useful, for example, to provide entrances for the housing units defined by horizontally adjacent structural units.
As FIGS. 1 and 4 show, system 100 is configured to support floor joists 160 across pairs of horizontally adjacent structural units spaced by a predetermined room width. In some examples, floor joists used with disclosed systems may define Hambro® brand floor joists. As FIG. 2 shows, a plurality of floor joists 160 extend across each pair of horizontally adjacent structural units at regular intervals along the entire length of the adjacent structural units.
FIG. 4 shows two pairs of horizontally adjacent structural units spaced by a predetermined room width, including first structural unit 110i spaced from second structural unit 110ii and second structural unit 110ii spaced from fourth structural unit 110iv. As FIG. 4 shows, floor joists 160 are configured to rest on the horizontal columns of the paired structural members.
As FIG. 5 illustrates, floor joists 160 are configured to extend straight across first structural unit 110i and second structural unit 110ii and third structural unit 110iii and fourth structural unit 110iv. FIG. 6 shows a close up view showing additional details of floor joists 160 resting on and being supported by third structural unit 110iii. As FIG. 6 shows, floor joists 160 define posts 162 that are configured to rest on the horizontal columns of structural units.
As FIG. 7 shows, floor joists 160 are configured to support a planar steel deck 162 to rest on floor joists 160 between horizontally adjacent structural units. In some examples the steel decks may extend over the entire area between horizontally adjacent structural units. The steel decks may be used to vertically support poured concrete at a floor level defined by the horizontally adjacent structural units flooring until the concrete dries. In the example shown in FIG. 7, system 100 supports floor joists 160 capable of supporting 1.5 inch steel decks 162 and 3.5 inch concrete slabs 164.
Though system 100 is configured to bear the entire minimum load necessary to support the building, pouring concrete floors may provide additional lateral stability to structural units.
As FIG. 2 shows, buildings constructed with system 100 may include concrete shear walls 89 around, for example, stairwells. This is not required, however. Further, concrete shear walls 89 are not necessary to satisfy the minimum load capacity of associated buildings.
As a result, system 100, when constructed, is configured to support independent of any additional load bearing supports, such as concrete columns. Indeed, this disclosure specifically contemplates that the disclosed modular, load-bearing support structures are capable of supporting at least the minimum load-bearing capacity selected to support structural elements of a multi-story building and the expected contents of the building.
The inventions described above may be alternatively described according to the following non-limiting embodiments.
In a first embodiment of a modular support system for supporting, a multi-story building, the modular support system may include a plate having a bottom major face and a top major face opposite the bottom major face, a vertical column extending from a bottom end to a top end opposite the bottom end, the bottom end of the vertical column being welded to the top major face of the plate, and a horizontal column having a bottom side and a top side opposite the bottom side, the bottom side of the horizontal column being welded to the top end of the vertical column.
In some examples of the first embodiment, the plate defines bolt holes extending from the top major face through the plate to the bottom major face.

In some examples with a second structural unit, the second structural unit comprises a second vertical column extending from a bottom end to a top end opposite the bottom end and the bottom end of the second vertical column is welded to the top major face of the second plate. In some examples having a second structural unit, the second structural unit comprises a second horizontal column having a bottom side and a top side opposite the bottom side, the bottom side of the second horizontal column being welded to the top end of the second vertical column.
Some examples including a second structural unit further comprise bolts extending through the bolt holes defined in the second plate and through the bolt holes defined in the top side of the horizontal column of the first structural unit to selectively couple the first structural unit with the second structural unit.

In some examples of the first embodiment, the horizontal column defines a wide-flange beam including a top flange defining the top side, a bottom flange spaced from the top flange, the bottom flange defining the bottom side, and a web extending between the top flange and the bottom flange. In some examples wherein the horizontal column defines a wide-flange beam, the bolt holes extend through the top flange.

Some examples defining a plurality of vertical columns, further comprise a second structural unit horizontally spaced from the first structural unit by a predetermined wall spacing distance and vertically aligned with the first structural unit.
