The invention relates generally to structural framed buildings, and, more specifically to modular components for structural framed buildings.
Structurally framed buildings generally include a steel or concrete frame of columns, girders, and beams that support concrete decks. Once installed, the concrete decks form the base of the various floors of the building. Building systems such as walls, facilities components (e.g., electrical, plumbing, and heating, ventilation, and air conditioning (HVAC) components), and equipment are then attached to the concrete deck to finish out the building. In the construction of structurally framed buildings, partitions may be inserted after placing the decks to create separate rooms or compartments on each deck. The various rooms may be tailored for specific uses depending on the position, size or other attributes of the partitions used for the rooms.
Non-load bearing partitions in the interior of a building provide a separation between spaces within the building without necessarily providing support to the building structure. Partitions may need to be resistant to fire, smoke and/or sound transmittance according to the various requirements and usages of the building. Partitions may be built from the floor of one building deck to the underside of the structural deck overhead in a contiguous manner to create a barrier to meet fire, smoke, and/or sound ratings.
An interior partition system for installation between a lower deck structure and an upper deck structure of a structural frame building is disclosed. The structural frame building has a ceiling line that defines a ceiling height of occupiable space within the structural frame building. The interior partition system includes a first, or lower, modular partition assembly for connection to the lower deck structure along a lower edge of the first modular partition assembly, and a second, or upper, modular partition assembly for connection to the upper deck structure along an upper edge of the second modular partition assembly. The interior partition system also includes a receptor structure configured to connect an upper edge of the first modular partition assembly to a lower edge of the second modular partition assembly. The first modular partition assembly has a vertical dimension that exceeds the ceiling height, such that the upper edge of the first modular partition assembly, the lower edge of the second modular partition assembly, and the receptor structure are located above the ceiling line upon installation of the first modular partition assembly, the second modular partition assembly, and the receptor structure in the structural frame building.
Other aspects and advantages of embodiments of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrated by way of example of the principles of the invention.

It will be readily understood that the components of the embodiments as generally described herein and illustrated in the appended figures could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of various embodiments, as represented in the figures, is not intended to limit the scope of the present disclosure, but is merely representative of various embodiments. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by this detailed description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
Reference throughout this specification to features, advantages, or similar language does not imply that all of the features and advantages that may be realized with the present invention should be or are in any single embodiment. Rather, language referring to the features and advantages is understood to mean that a specific feature, advantage, or characteristic described in connection with an embodiment is included in at least one embodiment. Thus, discussions of the features and advantages, and similar language, throughout this specification may, but do not necessarily, refer to the same embodiment.
Furthermore, the described features, advantages, and characteristics of the invention may be combined in any suitable manner in one or more embodiments. One skilled in the relevant art will recognize, in light of the description herein, that the invention can be practiced without one or more of the specific features or advantages of a particular embodiment. In other instances, additional features and advantages may be recognized in certain embodiments that may not be present in all embodiments of the invention.
Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the indicated embodiment is included in at least one embodiment. Thus, the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.
While many embodiments are described herein, at least some of the described embodiments present a system and method for constructing an occupiable space in a structural frame building. More specifically, the system is an interior partition system that uses modular partition assemblies to create occupiable spaces on a deck of a structural frame building. In one embodiment, the occupiable spaces are occupied by people and/or objects. The partition assemblies exceed a ceiling height and include upper and lower modular partition assemblies connected by a receptor structure above the ceiling height.
Several variables or issues may affect the construction of a structural frame building. For example, the top portion of a full height wall in the interior of a structural frame building is referred to as the “head of wall condition.” The head of wall condition exists at fire, smoke, and/or sound rated walls and because of variations in the design and construction of concrete decks, the head of wall condition may need to be evaluated individually in each steel framed building to ensure that applicable fire, smoke, and/or sound ratings are met. Acoustical properties may be measured using a sound transmission coefficient and correlate to decibel reduction of noise as it is transmitted through a partition. Fire and smoke resistance ratings may are properties of time, generally between forty-five minutes and four hours that partitions resist the transmission of fire or smoke from one side of the partition to the other.
Additionally, the anchoring of building systems, such as interior walls, facility components, and equipment to concrete decks is typically customized for each individual structural frame building. Further, the onsite customization of anchoring systems does not typically take into account any future needs and/or uses of the steel frame building.
In some conventional structural frame buildings, partitions are typically “stick” built or pre-assembled in panels in an offsite fabrication shop and brought to the site. Coordinating the design of the partition assemblies, internal utility routings, and anchoring/bracing to ensure that the requirements of the many components in combination are met can require tremendous effort. The assembly of the many different components can require valuable resource process time to be expended on each design and construction project that is often lost on future projects and has to be repeated, sometimes with similar errors.
In one embodiment, the structural frames 100 are steel frames. In one embodiment, the columns 102 are “I” shaped steel beams, referred to as “I-beams”. In general, the I-beams may be spaced apart in a grid structure that includes an X-span dimension and a Y-span dimension. For example, X and Y spans in the range of 10-70 feet and X and Y spans in the range of 20-40 feet are common, though other dimensions are possible. The structural frames 100 may be any type, shape, or material used for framing the framed building. The material for the framed building may include a composite of more than one material.
The spacing of the girders 104 may be determined by the spacing of the columns 102. The spacing of the beams 106 may be more flexible than the spacing of the girders 104. The beams 106 may be located between pairs of columns 102, and additional beams 106 may be located between columns 102.
In one embodiment, the structural frame 100 is a frame that defines a footprint of an occupiable building. The structural frame 100 includes at least one lower deck structure 200 located within the footprint of the frame and at least one upper deck structure 202 located within the footprint of the frame and supported by the building frame. An interior partition system is installed between the lower deck structure 200 and the upper deck structure 202 to define an occupiable space. Partition assemblies may be attached to the upper and lower decks 202, 200 to create occupiable spaces in the framed building. In an embodiment, the interior partition system includes partition assemblies that are not exposed to the outside environment, but are contained within an interior space of the framed building.
In various embodiments, the concrete decks may be pre-fabricated and assembled onsite or formed onsite in the structural frame 100. The shape of the decks may be determined by the shape and positioning of the columns 102, girders 104, and beams 106 of the structural frame 100, as well as the location of the decks in the structural frame 100. Additionally, the spacing between the decks may include space for habitation spaces as well as any utility routings, anchors, braces, or other components needed for the operation or structure of the building. In one embodiment, the exact size and shape of the decks is governed in part by at least one of the following parameters: structural performance requirements of the structural frame 100; the framing geometry of the structural frame 100; transportation requirements of the jurisdictions in which the decks are transported on public roads; and vehicle availability for transport.

The upper partition assembly 204 is connected to the lower partition assembly 206 by a receptor structure 604 at a receptor joint to form a single modular partition or panel that fully extends from the lower deck 200 to the upper deck 202. The upper partition assembly 204 has a vertical dimension that exceeds the ceiling height. The upper partition assembly 204 may include an upper receptor structure at a lower edge of the upper partition assembly 204 that attaches to a lower receptor structure at the upper edge of the lower partition assembly 206. The upper edge of the lower partition assembly 206, the lower edge of the upper partition assembly 204, and the receptor structures 604 are positioned above the ceiling line 302. In some embodiments, the partition assemblies 204, 206 include a brace 400 or metal strap 404 that is positioned between or in accordance with the lower receptor structure and the upper receptor structure and attaches to the bottom surface 406 of the upper deck 202. The brace 400 may provide additional structural support for the partition assemblies 204, 206. Because the partition assemblies 204, 206 of
Modules formed using the interior partition assemblies may be rectangular, square, or a custom shape defined by the partition assemblies. The modules may share walls formed by partition assemblies. In some embodiments, multiple partition assemblies may form a single wall, thus allowing the customization of the size and shape of each module. The modular partition assemblies 300 may include openings 500 for doors, windows, vents or other utilities and components in either the upper or lower partition assemblies 204, 206.
After the modular partition assemblies 300 have been attached to the upper deck 202 and the lower deck 200 and to other modular partition assemblies 300, drywall, plaster, and/or other finishings may be applied to the modular partition assemblies 300, and the structural frame building may be finished. The type of sheathing used to cover the partition assemblies may be dependent on the specific requirements of the structural requirements and/or use of the space that is enclosed by the partition system. The partition assemblies may receive sheet metal backing plates 502 in some embodiments.
In one embodiment, many of the in-wall utilities are placed in the lower partition assemblies 206, including piping, electric and low voltage services, and other utilities. The utilities may be routed horizontally, vertically, or both horizontally and vertically. Other routing directions may also be used. Larger utility openings 500 and penetrations may be included in the upper partitions assemblies above the ceiling line 302. The modular partition assemblies 300 may include an anchorage area for wall-hung equipment or accessories, particularly on the lower partition assemblies 206 below the ceiling line 302. The modular partition assemblies 300 may help streamline overhead mechanical, electrical, and plumbing coordination by providing predictable locations for bracing and other secondary structure members.
The upper and lower partition assemblies 204, 206 are joined at a semi mid-span receptor joint that accommodates inter-story vertical deflection movement when the loading and/or movement of one floor is different than the others, as well as accommodating deviations in on-site construction techniques. The receptor joint may also provide flexibility of the upper and lower components to be joined. This may include shifting the deflection movement of full height partitions from the head of wall to the mid-span, allowing for a site adaptable, tight, non-moving connection that may be made more simply than making the connection and providing movement at the head of wall. The receptor joint may be placed along a datum height on the floor. The datum height provides a point of reference for the lower and upper partition assemblies 204 to be installed. The receptor structure 604 may provide traditional double track deflection or slotted track deflection. The receiving track for the lower partition assembly 206 may allow for non-regular floor-to-floor height.
The location and structure of the interior modular partition assemblies 300 may be determined using an automated process. Each panel using the modular partition assemblies 300 may be interchangeable with other panels. Changes in the design or construction of the partition assemblies may be easier to incorporate than conventional systems because the panels are made with a regularized centered dimensioning system (for example, 2″, 3″, 4″ or 5″) to meet the unique needs of the specific installations.
In one embodiment, the horizontal spacing of the vertical studs 600 is configured such that the partition resists flexural movement in the drywall, as well as the orthogonal deflection in the partition. For example, the horizontal spacing may be no more than twenty-four inches on center. In some embodiments, studs 600 may be place directly adjacent to one another proximate an opening 500 in the panel and fastened together to add additional support.
The framing members may be fastened to each other by screwing, pinching, punching or welding the individual pieces based on the structural requirements of the modular partition assemblies 300. Anchoring the partition assemblies to the building structure may be determined based on site-specific needs.
In one embodiment, each modular partition assembly has a minimum width of 6 inches and a maximum width of 25 feet. In some embodiments, partition assemblies having a width wider than 25 feet may require a control joint for proper installation. In one embodiment, each of the upper and lower partition assemblies 204, 206 has a maximum height of 10-20 feet.
The upper partition assembly 204 includes an upper receptor structure 700 at a lower edge of the upper partition assembly 204. The lower partition assembly 206 includes a lower receptor structure 702 at an upper edge of the lower partition assembly 206. In some embodiments, the upper receptor structure 700 and the lower receptor structure 702 may be joined to the upper partition assembly 204 and the lower partition assembly 206, respectively. In one embodiment, the lower receptor structure 702 is adjustably connected to the lower partition assembly 206, while the upper partition assembly 204 may not be fixed to the upper receptor structure 700, but rather sits in the upper receptor structure 700. Furthermore, the upper receptor structure 700 and the lower receptor structure 702 may be fastened together to fix or partially fix the upper partition assembly 204 with respect to the lower partition assembly 206. The upper and lower receptor structures 700, 702 may be fastened together through holes 704 or slots in the adjoining surfaces of the upper and lower receptor structures 700, 702.
Vertical slots 708 in the lower receptor structure 702 allow the lower receptor structure 702 to be raised or lowered before fastening the lower receptor structure 702 to the vertical stud 600 with a fastener 710 within one of the vertical slots 708. In one embodiment, the lower receptor structure 702 is fastened to the vertical stud 600 according to an adjustable vertical position of the lower receptor structure 702 relative to a fixed position of the lower partition assembly 206.
Because the lower receptor structure 702 is adjustably connected to the lower partition assembly 206, a vertical position 714 of the lower receptor structure 702 may be adjusted to allow the lower receptor structure 702 to abut the lower receptor structure 702, after which the lower receptor structure 702 may then be fastened to the lower partition assembly 206 and to the upper receptor structure 700.
In one embodiment, the lower receptor structure 702 includes a tab 800 on each side of the lower receptor structure 702. As shown in the embodiments of
Dimension A has a minimum nominal height of 1 inch and a maximum nominal height of 6 inches. Dimension B has a minimum nominal width of 2 inches and a maximum nominal width of 10 inches. Dimension F has a minimum nominal width of ¼ inches and a maximum nominal width of 3 inches. The lower receptor structure 702 includes a maximum length of 25 feet. The lower receptor structure 702 has a minimum gauge of 20 and a maximum gauge of 14. The gauge may indicate a thickness of the material used for the lower receptor structure 702.
Each slot in the lower receptor structure 702 has a minimum width 802 of 1/16 inches and a maximum width 802 of 3/16 inches. The minimum spacing 804 between the slots is 1 inch on center and the maximum spacing 804 is 6 inches on center. Dimension C has a minimum width of ¼ inch, and Dimension E also has a minimum width of ¼ inch. Dimension D, which is the slot length, includes the remaining width of dimension A after subtracting dimensions C and E. The lower receptor structure 702 also includes holes 704 to receive a fastener 710 that attaches the lower receptor structure 702 to the upper receptor structure 700. The holes 704 may be configured according to the type of fastener used and the spacing of holes 704 in the upper receptor structure 700.
The lower receptor structure 702 accommodates variations in construction tolerances of onsite conditions. The construction of floors on each deck and undersides of decks may have ranges of tolerances that can be as high as 1 inch within 10 feet. In one embodiment, the lower receptor structure 702 may absorb a range of variation as much as 3 inches. The lower receptor structure 702 may be installed at a common vertical height to receive any partition assembly that rises above the ceiling line 302.
The upper receptor structure 700 may also include openings 900 in each side for heavier gauge support elements. In one embodiment, the support element may be the brace 400 as shown in
In one embodiment, the framing members include a minimum nominal width 1002 of 3⅝ inches and a maximum nominal width 1002 of 10 inches. The minimum nominal length 1000 is 1⅝ inches and the maximum nominal length 1000 is 8 inches. Other embodiments may include framing members with different sizes than described herein. In some embodiments, the horizontal tracks 402 may have similar measurements or structure to the upper receptor structures 700.
The receptor joint provides vertical deflection between the interior partition assembly and the lower deck 200. In one embodiment, deflection includes the movement of one level differentiated by the movement or lack of movement of another floor. For example, one deck may have a live load that causes the entire deck to sag compared to another deck that does not have a similar live load. The difference in loading may cause one of the decks to move and cause deflection/stress in the partition assemblies.
The receptor joint may provide predictability in a building life cycle requirement because the receptor joint provides a common height for all partition assemblies and structurally attaches the partition assemblies to the frame structure.
The upper and lower receptor structures 700, 702 may be placed (but not necessarily fixed) on the corresponding partition assemblies before or after installing the partition assemblies. In one embodiment, the upper and lower receptor structures 700, 702 are slid onto the corresponding partition assemblies after the partition assemblies are fixed to the corresponding decks, and then the upper and lower receptor structures 700, 702 are fixed to each other and to the partition assemblies.
In one embodiment, an upper and a lower partition assembly 206 are fastened to the respective decks prior to placing the decks in the structural frame 100. The placement of the modular partition assemblies 300 may be such that when the decks are placed in the structural frame 100, the upper partition assembly 204 and the lower partition assembly 206 are placed sufficiently close to each other to be able to connect the upper partition assembly 204 to the lower partition assembly 206 together via the receptor structure 604 without unfastening either of the modular partition assemblies 300 from the decks. This may allow some of the framed building to be pre-assembled onsite or at an offsite location.
In one embodiment, the attachment elements 1300 are solid tapered and internally threaded cylinders placed in openings or cavities in the decks. In another embodiment, the attachment elements 1300 include channel tracks that are set within the decks and covered with a cap that may be removed on an as-needed basis. The locations of the channel track may correspond to the specific design requirements of the framed building design criteria. Other embodiments of attachment elements 1300 may be used in conjunction with the upper and/or lower decks 202, 200.
The upper partition assemblies 204 may be attached to attachment elements 1300 at the bottom surface 406 of the upper deck 202, and the lower partition assemblies 206 may be attached to attachment elements 1300 at the top surface of the lower deck 200. Other building components may also be attached to attachment elements 1300 in either the upper deck 202 or the lower deck 200.
When the lower receptor structure 702 is in the lowered position, a gap 706 may be present between the lower receptor structure 702 and the upper receptor structure 700. In order to close the gap 706 and secure the upper and lower partition assemblies 204, 206 to each other, the position of the lower receptor structure 702 may be adjusted. In one embodiment, a fastener 710 through one of the slots 708 in the lower receptor structure 702 that is used to secure the lower receptor structure 702 to a vertical stud 600 in the lower partition assembly 206 may be loosened while adjusting the lower receptor structure 702. As shown in
The interior partitioning system described herein includes a receptor joint with a lower vertical position on the partition assemblies, thus reducing the chance that smoke 1502 rising and accumulating at the ceiling will be able to transfer through the partition assembly. Additionally, because the upper partition assembly 204 is fixed to the upper deck 202, rather than to the floor, variations in the distance between the lower deck 200 and the upper deck 202 do not affect the position of the upper edge of the upper partition assembly 204 with respect to the upper deck 202. This may allow the upper partition assembly 204 to be installed flush or approximately flush with the upper deck 202, thereby reducing the space between the upper deck 202 and the partition assemblies.
Various embodiments of a non-load bearing interior partition system for a structural frame building have been described above. The interior partition system may be used in conjunction with a method for constructing an occupiable space in a structural frame 100 having a lower deck 200 and an upper deck 202 and having a ceiling line 302 that defines a ceiling height of the occupiable space within the structural frame building.
The method includes fastening the lower modular partition assembly to the lower deck 200 along the lower edge of the lower partition assembly 206, and fastening the upper modular partition assembly to the upper deck 202 along the upper edge of the upper partition assembly 204. After installing the upper and lower partition assemblies 204, 206, the method connects the upper edge of the lower partition assembly 206 to the lower edge of the upper partition assembly 204 via the receptor structure 604. The upper edge of the lower partition assembly 206, the lower edge of the upper partition assembly 204, and the receptor structure 604 are located above the ceiling line 302 of the occupiable space.
In one embodiment, connecting the lower partition assembly 206 to the upper partition assembly 204 via the receptor structure 604 includes adjusting the receptor structure 604 to fill a gap 706 between the upper edge of the lower partition assembly 206 and the lower edge of the upper partition assembly 204. Adjusting the receptor structure 604 may include adjusting a height or vertical dimension of the receptor structure 604 relative to the upper edge of the lower partition assembly 206.
In one embodiment, connecting the upper edge of the lower partition assembly 206 to the lower edge of the upper partition assembly 204 includes securing the receptor structure 604 to the lower edge of the upper partition assembly 204 and/or to the receptor structure 604 to the upper edge of the lower partition assembly 206.
In the above description, specific details of various embodiments are provided. However, some embodiments may be practiced with less than all of these specific details. In other instances, certain methods, procedures, components, structures, and/or functions are described in no more detail than to enable the various embodiments of the invention, for the sake of brevity and clarity.
Although specific embodiments of the invention have been described and illustrated, the invention is not to be limited to the specific forms or arrangements of parts so described and illustrated. The scope of the invention is to be defined by the claims appended hereto and their equivalents.
