FIG. 2A illustrates an example exploded view of a floor assembly 200 of a modular building unit. The floor assembly 200 may be arranged in accordance with at least one embodiment described in the present disclosure. The floor assembly 200 may include a first floor section 210a, a second floor section 210b, and a third floor section 210c, referred to as the floor sections 210. In some embodiments, the number of sections of the floor assembly 200 may correspond with a configuration of a frame of a modular building unit, such as the frame 110 of the modular building unit 100 of FIG. 1B. Thus, in some embodiments, the number of sections may be more or fewer than three as illustrated.

In some embodiments, each of the floor sections 210 may include two floor end panels 202 and one or more floor panels 204. A number of floor panels 204 may vary and may be determined based on the opening size of the frame into which the floor panels 204 are to be installed. Two floor end panels 202 may be placed on opposite sides of a floor section 210 and any number of floor panels 204 may be placed between to fill the remaining space in an opening of the frame. Floor end panels 202 may be placed at the ends of a floor section 210 due to their flat end surface which may rest flat against the frame. The floor end panels 202 and the floor panels 204 may be arranged and fitted together to create a flat surface for the floor assembly 200.

In some embodiments, the panels of the floor assembly 200, such as the floor end panel 202 and the floor panel 204, may be made of any material including wood, concrete, aircrete, high density foam, aluminum and metal or any combination of the listed materials or other materials. Panels made of materials such as concrete or aircrete may have steel bars and/or wire mesh reinforcement within the panels. For example, in some embodiments, the floor end panels 202 and the floor panels 204 may be made from aircrete. In these and other embodiments, the floor end panels 202 and the floor panels 204 may be individually constructed or constructed from a mold at a manufacturing facility. By using aircrete, the floor end panels 202 and the floor panels 204 may provide strength to the building but may also allow people to easily lift and install the floor end panels 202 and the floor panels 204 without heavy machinery or needing multiple different construction components. As an example, the floor end panels 202 and the floor panels 204 may weigh 15 pounds to 150 pounds per panel.

In some embodiments, a width of the floor end panels 202 and the floor panels 204 may be configured such that the length of the frame and the width of the floor end panels 202 and the floor panels 204 are compatible such that the length of the frame divided by the width of the floor end panels 202 and the floor panels 204 may be an integer value. The length, width, and depth of the panels may vary and may be based on the dimensions of the frame into which the panels may be installed.

In some embodiments, the floor end panels 202 may have a length ranging from 1 foot to 10 feet, a width ranging from 4 inches to 4 feet, and a depth ranging from 2 inches to 10 inches. The floor end panel 202 may include a notch in one end of the panel that may form a flange. The flange may be mated with a flange of a floor panel 204 to join the floor end panel 202 and the floor panel 204 together. The notch may extend the entire length of floor end panel 202 and may begin on the width surface. The notch may be 0.5 inches to 5 inches in depth into the floor end panel 202 to approximately a center the depth of the floor end panel 202 and may be 0.5 inches to 8 inches in width. The notch may occur on one side of the floor end panel 202 to allow for a flat surface on the other end. Floor end panel 202 may have a width ranging from 4 inches to 4 feet on one surface and a smaller width on the opposite surface with the notch.

In some embodiments, the floor panels 204 may have a length ranging from 1 foot to 10 feet, a width ranging from 4 inches to 4 feet, and a depth ranging from 2 inches to 10 inches. The floor panel 204 may have a notch in both sides of the floor panel 204 that may form a flange on both sides of the floor panel 204. The flange may be configured to join or mate with a flange of another floor panel 204 or floor end panel 202. The flange may mate with another flange by extending over the other flange such that a surface area of the flanges are in contact and support each other. The notch may extend the entire length of floor panel 204 and begins on the width surface. The notch may be 0.5 inches to 5 inches in depth into the floor panel 204 to approximately a center the depth of the floor panel 204 and may be 0.5 inches to 8 inches in width. The notch may occur on opposite sides of both width surfaces of floor panel 204. Floor panel 204 may have a width ranging from 4 inches to 4 feet on both surfaces with the notch at opposite sides.

FIG. 2B illustrates an example of the floor end panels 202 and the floor panels 204 of FIG. 2A from a different perspective. The number of panels may vary from the illustration. A number of panels assembled together may be determined based on the dimensions of the floor assembly 200. The floor end panels 202 and the floor panels 204 are assembled together using the notches to join each end. For example, the notches of two floor panels 204 may be rested on top or below each other. Floor end panels 202 may be placed with the notch facing opposite directions, such as one facing up and another facing down, on both ends of the floor section 210. Floor panels 204 may be placed in the remaining space with each floor panel 204 including a first notch resting on top of a notch of another floor panel 204 and a second notch being below are carrying another notch of another floor panel 204. During construction of the floor assembly 200, the floor end panels 202 and the floor panels 204 may be placed one after another within a frame to form the floor assembly 200. Floor panels 204 may be joined to other floor panels 204 from either side of the floor panels 204.

In some embodiments, an orientation of the floor panels 204 during construction may not be important because the floor panels 204 are symmetrically designed such that floor panels 204 have the same configuration regardless of the orientation of the floor panels 204. As a result of the symmetric design, the construction burden may be reduced. Thus, the design of the floor end panels 202 and the floor panels 204 may allow for joinery with reduced complexity and easier installation.

In some embodiments, the floor assembly 200, wall panels 300 and roof assembly 400 may be assembled similarly. The panels may have the same installation and joinery method as illustrated in FIG. 2B. In some instances, the panels may vary in size but the assembly method remains the same throughout the panel types. The joinery on the ends of the panels such as the notches may be one of many other shapes used to join panels together. Various other shapes and sizes of end joints may be used to connect panels together. For example, another joinery method of panels may be with a male and female design where the end of one panel may be inserted into an opening in the end of the panel next to it. Alternatively, panels may have flat ends with a frame around one or more sides of each panel and the ends of the panel frames may connect the panels together, holding the panels into place.

In some embodiments, the floor end panels 202 and the floor panels 204 may be set into a frame one or more at a time. The floor end panels 202 and the floor panels 204 may rest on a bottom flange of an angle, such as bottom angle 950a, illustrated in FIG. 9D, positioned perpendicular to the placement of the floor end panels 202 and the floor panels 204 and along the long side of the frame. The bottom flange of the angle 950a may support the floor end panels 202 and the floor panels 204. For example, the bottom flange may support from 1 inch to 8 inches of the floor end panels 202 and the floor panels 204.

In some embodiments, the floor end panels 202 may rest on a bottom flange of an angle, such as an angle base trim 930d, illustrated in FIG. 9C, positioned parallel to the floor section 210 along a side of the frame. The bottom flange of the angle may support the floor end panels 202 from 1 inch to 4 inches of the floor end panels 202. In some embodiments, a lower opening of the frame 110 may include two forklift pockets, such as the forklift pockets 970 illustrated in FIG. 9B, which may extend through the entirety of the frame 110 dividing it into three openings. Floor end panels 202 and the floor panels 204 may be placed one at a time within the three openings of the frame 110 extending horizontally and parallel to the short side of the frame 110. The floor end panels 202 next to the forklift pockets may rest on a plate, such as forklift plates 970b, positioned parallel to the floor end panels 202 and attached to the forklift HSS tube 970a. The plate may support from 1 inch to 4 inches of floor end panels 202. The frame 110 may support the weight of the floor assembly 200.

In some embodiments, a floor end panel 202 may be placed at each end of the floor assembly 200 to create a flat surface close to the frame side. The floor end panel 202 may be rotated 180 degrees to be placed with the notch facing up or down. One floor end panel 202 may have a notch facing up and another floor end panel 202 may have a notch facing down with any number of floor panels 204 in between to complete the floor assembly 200 for an entirely flat floor surface.

FIG. 2C illustrates an example exploded view of a floor assembly 200 of a modular building unit that includes secondary flooring 206. The floor assembly 200 may be arranged in accordance with at least one embodiment described in the present disclosure. In some embodiments, after the floor sections 210 are aligned into position, a secondary flooring 206 may be installed on top of the floor sections 210. The secondary flooring 206 may be installed in accordance with typical flooring construction practices which may vary based on the finished material of choice. The secondary flooring may be a plywood sub-flooring, a water barrier and a finished flooring material installed on top. There may be round or rectangular openings in the floor end panels 202, floor panels 204 and secondary flooring 206 to allow MEP systems to be installed inside the unit.

FIGS. 3A-3C illustrates an example exploded view of wall assemblies 310 of a modular building unit built using wall panels 300. The wall assemblies 310 may be arranged in accordance with at least one embodiment described in the present disclosure. FIGS. 3A-3C illustrate a wall assembly 310a configured for a door, a wall assembly 310b configured for a window, and a solid wall assembly 310c, referred to collectively as the wall assemblies 310.

In some embodiments, the number of the wall assemblies 310 configured for a door and/or a window that may be used in a modular building unit may vary and correspond with different configurations of the modular building unit floor plan, as illustrated in FIGS. 11A-11D. Thus, in some embodiments, the wall panels 300 may be joined in other various assemblies than those illustrated in wall assemblies 310. The wall assemblies 310 may be arranged in accordance with at least one embodiment described in the present disclosure. The wall assemblies 310 may include one or more wall panels 300 including a wall end panel 302, a wall panel 304, a window side panel 306, a window base panel 308, and a window top panel 310. Included in the wall assemblies 310 may be one or more openings such as a door opening 320a or a window opening 320b. In some embodiments, the number of wall panels 300 may correspond with a configuration of a frame of the modular building unit, such as the frame 110 of the modular building unit 100 of FIG. 1B.

In some embodiments, the number of doors 320a and/or windows 320b included in the wall assemblies 310 may vary and correspond with different configurations of the modular building unit floor plan, as illustrated in FIGS. 11A-11D. The number of wall panels 300 may vary and may be determined based on the length of the short side or long side wall of a frame. During construction, two wall end panels 302 may be placed on opposite sides of frame 110 with their notches facing opposite directions. Any number of wall panels including 302, 304, 306, 308 and 310 may be placed between the two wall end panels 302 to fill the remaining space and create openings for doors 320a and/or windows 320b. Wall end panels 302 may be placed at the ends of the wall assembly 310 due to their flat end surface which may rest flat against the frame. The wall panels 300 may be arranged and fitted together to such that the wall panels 300 when assembled in a wall assembly 310 include a flat surface on one or both sides of the wall assembly 310.

In some embodiments, the wall panels 300 of the wall assemblies 310, such as the wall end panel 302, the wall panel 304, the window side panel 306, the window base panel 308 and the window top panel 310 may be made of any material including wood, concrete, aircrete, high density foam, aluminum and metal or any combination of the listed materials or other materials. Panels made of materials such as concrete or aircrete may have steel bars and/or wire mesh reinforcement within the panels. For example, in some embodiments, the panels may be made from aircrete. In these and other embodiments, the wall panels 300 may be individually constructed or constructed from a mold at a manufacturing facility. By using aircrete, the panels may provide strength to the building but allow people to easily lift and install the wall panels 300 without heavy machinery or needing multiple different construction components. Wall panels 300 may weigh 15 pounds to 150 pounds per panel.

In some embodiments, a width of the wall panels 300 may be configured such that the length of the frame and the width of the wall panels 300 are compatible, such that the length of the frame divided by the width of the wall panels 300 may be an integer value. The length, width, and depth of the panels may vary and may be based on the dimensions of the frame into which the panels may be installed.

FIG. 3A illustrates an example exploded view of a wall assembly 310a of a modular building unit. The illustrated wall assembly 310a may be an example of a wall with a door 320a. The number of openings in the completed wall assembly within the frame for doors 320a may vary and correspond with different configurations of the modular building unit floor plan, as illustrated in FIGS. 11A-11D.

In some embodiments, the wall assembly 310a may include wall end panels 302 and a door 320a. The number of wall panels 300 may vary based on the sizing of the frame and the number of doors 320a may vary and correspond with different configurations of the modular building unit floor plan, as illustrated in FIGS. 11A-11D. Wall end panels 302 may be arranged to leave an opening in the center for a door 320a. Wall end panels 302 may be joined together on either side of door 320a which may be centered in the wall assembly 310a. Wall end panels 302 may be joined together with their notches facing inward and the flat end surface facing outward to rest against the frame and the door 320a. Two wall panels 300 may be joined by mating the flanges of the two notches together. The wall assembly 310a may be an example of one or more configurations of a wall that may be assembled using wall panels 300 and wall end panels 302.

In some embodiments, the wall panels 300 may be positioned into a frame one panel at a time. Wall panels 300 may be installed similarly on the short and long sides of the frame 110. Before installing wall panels 300 on the short side of the frame, trim plates, such as trim plates 930b and 940d illustrated in FIG. 9C, may be installed on either the top or bottom of the frame 110. Before installing wall panels 300 on the long side of the frame, trim plates, such as trim plates 950b, 950c and 960b illustrated in FIG. 9D, may be installed on either the top or bottom of the frame 110. Trim plates may be attached perpendicular to a c-channel, such as a c-channel 920b or c-channel 920c illustrated in FIG. 9B, at the top and bottom. Trim plates may cover 1 inch to 8 inches of the top surface and/or bottom surface of wall panels 300. To position wall panels 300 into place within frame 110, wall panels 300 may be inserted between the trim plates first at the top or bottom before positioning the opposite side of the panel. By attaching the trim plates to the c-channel before installing the wall panels 300, the trim plates may provide a more secure installation to keep wall panels 300 from moving out of position. The wall end panels 302 may be placed into the c-channels 920b or 920c positioned parallel to the placement of the wall panels 300 and along the frame. The c-channels 920b or 920c may cover 1 inch to 8 inches of the surface of the wall end panel 302. The remaining wall panels 300 may be positioned into place on top of hollow structural sections (HSS) on the short side frame, such as a HSS 930a illustrated in FIG. 9C or on top of floor assembly 200 on the long side and within the trim plates. The remaining trim plates may be installed on the top or bottom remaining locations, attaching to the perpendicular c-channel. By attaching the trim plates, the wall panels 300 may be secured into place to restrict their movement.

In some embodiments, the wall end panels 302 may have a length ranging from 1 foot to 10 feet, a width ranging from 4 inches to 4 feet, and a depth ranging from 2 inches to 10 inches. Wall end panel 302 may have a notch in one end of the panel that may form a flange. The flange may be mated with a flange of other wall panels 300 to join panels together in a similar manner as the floor end panels 202 and the floor panels 204 may be joined together.

The roof top end panel 402, the roof panel 404 and the roof bottom end panel 406, may be referred to collectively as the roof panels 402, 404, and 406. In some embodiments, the number of roof panels 404 of the roof assembly 400 may correspond with a configuration of a frame of the modular building unit, such as the frame 110 of the modular building unit 100 illustrated in FIG. 1B.

In some embodiments, the roof assembly 400 may include one or more roof top end panels 402 and one or more roof bottom end panels 406. A number of roof panels 404 may vary and may be determined based on the opening size of the frame into which the roof panels 404 are to be installed. Roof top end panel 402 and roof bottom end panel 406 may be placed on opposite sides of roof assembly 400 and any number of roof panels 404 may be placed between to fill the remaining space in an opening of the frame. Roof top end panel 402 may be placed at one end of roof assembly 400 and roof bottom end panel 406 may be placed at the opposite end of roof assembly 400. Roof top end panel 402 and roof bottom end panel 406 may be placed at the ends of the roof assembly 400 due to their flat end surface which may rest flat against the frame. Roof top end panels 402 and roof bottom end panels 406 may be placed with the flat width surface facing down and with the gutter channel facing up when placed in the frame. The roof panels 402, 404, and 406 may be arranged and fitted together to create a flat surface for the roof assembly 400. The design of the roof panels 402, 404, and 406 may allow for joinery with reduced complexity and easier installation.

In some embodiments, each of the roof panels 402, 404, and 406 may have one or more gutter channels on a surface, such as a width surface. The gutter channel may be in the shape of a semi-circle or half circle where half of the diameter may be cut through the roof panels 402, 404, and 406. In some embodiments, first and second gutter channels may be cut into the same width surface of the roof panels 402, 404, and 406 on opposite sides of the roof panels 402, 404, and 406. A gutter channel may be cut through the roof panels 402, 404, and 406 and may have a diameter of 1 inch to 8 inches. As an example, a gutter channel may begin 2 inches to 18 inches from the sides of the roof panels 402, 404, and 406 to a center point of the gutter channel along the width surface of the roof panels 402, 404, and 406. A gutter channel may cut through the entire width of the roof panels 402, 404, and 406. Gutter channels of the panels 402, 404, and 406 may face up when placed into the frame. The gutter channels may be located near ends of the panels 402, 404, and 406. Alternately or additionally, the gutter channels may be located such that at least a distance there between is within a range of 40 to 99 percent of the length of the panels 402, 404, and 406. For example, the gutter channels may be located such that at least a distance there between is at least 40, 50, 60, 70, 80, or 90 percent of the length of the panels 402, 404, and 406. For example, if the length of a panel is 5 ft, the gutter channels may be located such that 80 percent of the length of the panel, i.e. 4 is positioned there between such that the gutter channels are located 6 inches from the edges of the panel.

In some embodiments, the gutter channel in the roof panels 402, 404, and 406 may serve a function for water drainage off the roof. The slope of the roof and the gutter channel may range in size based on the climate the modular building unit 100 is located. For example, some climates may need a smaller or larger gutter based on the annual rainfall. The gutter channel may be on both ends of roof assembly 400 due to the slope of the roof. The roof peak may be in the center of the modular building unit 100 and slopes out towards the long sides of the frame which may lead water to drain into the gutter channel. The roof slope on the far edges of the roof assembly 400 may slope towards the center of the roof which may lead water to drain into the gutter channel from the opposite direction. The water in the gutter channel may drain through the circular opening in HSS tube 940a, illustrated in FIG. 9C, and down to the ground. The number of gutter channels and roof peaks may vary based on the desired level of drainage and desired roof slope.

In accordance with common practice, the various features illustrated in the drawings may not be drawn to scale. The illustrations presented in the present disclosure are not meant to be actual views of any particular apparatus (e.g., device, system, etc.) or method, but are merely idealized representations that are employed to describe various embodiments of the disclosure. Accordingly, the dimensions of the various features may be arbitrarily expanded or reduced for clarity. In addition, some of the drawings may be simplified for clarity. Thus, the drawings may not depict all of the components of a given apparatus (e.g., device) or all operations of a particular method.

Terms used herein and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including, but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes, but is not limited to,” etc.).

Additionally, if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations.

In addition, even if a specific number of an introduced claim recitation is explicitly recited, it is understood that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” or “one or more of A, B, and C, etc.” is used, in general such a construction is intended to include A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B, and C together, etc. For example, the use of the term “and/or” is intended to be construed in this manner.

Further, any disjunctive word or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” should be understood to include the possibilities of “A” or “B” or “A and B.”

Additionally, the use of the terms “first,” “second,” “third,” etc., are not necessarily used herein to connote a specific order or number of elements. Generally, the terms “first,” “second,” “third,” etc., are used to distinguish between different elements as generic identifiers. Absence a showing that the terms “first,” “second,” “third,” etc., connote a specific order, these terms should not be understood to connote a specific order. Furthermore, absence a showing that the terms first,” “second,” “third,” etc., connote a specific number of elements, these terms should not be understood to connote a specific number of elements. For example, a first widget may be described as having a first side and a second widget may be described as having a second side. The use of the term “second side” with respect to the second widget may be to distinguish such side of the second widget from the “first side” of the first widget and not to connote that the second widget has two sides.

All examples and conditional language recited herein are intended for pedagogical objects to aid the reader in understanding the invention and the concepts contributed by the inventor to furthering the art, and are to be construed as being without limitation to such specifically recited examples and conditions. Although embodiments of the present disclosure have been described in detail, it should be understood that the various changes, substitutions, and alterations could be made hereto without departing from the spirit and scope of the present disclosure.
