## Background
GOVERNMENT LICENSE RIGHTS
This invention was made with government support under Contract No. N00164-05-C-6084 awarded by the U.S. Navy which is a branch of the U.S. Department of Defense. The invention was further made with government support under Contract No. N61331-10-C-0014 also awarded by the U.S. Navy.


FIELD OF THE INVENTION
This invention relates to modular structure, and more particularly, to apparatus and methods for rapid assembly of modular structures.
BACKGROUND OF THE INVENTION
In some circumstances, particularly in military applications, it may be desirable to provide temporary shelters for personnel and/or equipment. For example, it is desirable to provide a temporary shelter for military personnel who are being transported on a military vehicle, such as a hovercraft, that does not have sufficient cabin space for the military personnel to safely reside during transport. The temporary shelter is assembled on the deck of the military vehicle and protects the military personnel during transport.
Typically, the applications for the temporary shelters dictate that the temporary shelters be assembled rapidly without burdening the assemblers with a complex assembly process, yet provide an adequate shelter for the personnel and/or equipment housed in the temporary shelter. For example, the temporary shelters are often times assembled in a remote location to provide shelter for personnel and/or equipment during execution of short-term missions. The total amount of time the personnel are in the remote location is often times minimal so the portion of time committed in the assembly of the shelter has to be minimized. The temporary shelter is also required to provide adequate protection for the personnel and/or equipment by, for example, providing protection from weather elements, fire, and/or high sound levels. A complex assembly process of the temporary shelter adds to the amount of time allotted to the assembly of the temporary shelter, yet the assembly process cannot be simplified to the point that the temporary shelter no longer provides an adequate shelter.
Conventional temporary shelters, such as conventional personnel transport modules (PTM) used in the transport of military personnel, typically have issues that include but are not limited to corrosion, water leakage, and/or difficulty in assembly. The conventional PTM is assembled with panels made of a composite material that includes a foam inner layer that is between two outer layers of aluminum. The aluminum is bounded to the foam with polyurethane. The polyurethane absorbs moisture and then delaminates resulting in corrosion of the conventional PTM. The conventional PTM also does not include a moisture absorbing material between each panel to protect the conventional PTM from leaking moisture into the conventional PTM.
The panels of the conventional PTM are assembled together with ratchet locks. Each respective panel must be directly aligned with each other panel for the ratchet locks to sufficiently lock each respective panel together in forming the conventional PTM. The ratchet locks fail to provide tolerance levels in the alignment of each respective panel that would enable each panel to not have to be directly aligned with each other for the ratchet locks to sufficiently lock each panel together. The difficulty provided in directly aligning each respective panel with each other complicates the assembly process and adds unnecessary time in assembling the conventional PTM. Therefore, an effective means to provide and assemble a modular shelter that can be easily assembled but yet provide adequate protection is needed.

The following Detailed Description of the exemplary embodiments will so fully reveal the general nature of the present disclosure that others can, by applying knowledge of those skilled in the relevant art(s), readily modify and/or adapt for various applications such exemplary embodiments, without undue experimentation, without departing from the scope of the present disclosure. Therefore, such adaptations and modifications are intended to be within the meaning and plurality of equivalents of the exemplary embodiments based upon the teaching and guidance presented herein.

For a more efficient modular structure and assembly thereof, the present invention implements a roof and panel joining assemblies with modular panels to create a substantially moisture proof structure that is scalable and easily assembled. The modular structure is assembled with pre-fabricated modular panels that are transported as individual pieces to the location where the modular structure is to be assembled and then assembled into the modular structure. Each modular panel of the modular structure is implemented as a supporting structure for the modular structure, i.e., a wall, roof, and/or floor for the modular structure. Each modular panel may be sized accordingly based on structural loading requirements, fire requirements, and/or any other design and/or performance requirements that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure.
One of ordinary skill in the art will recognize that the modular structure is scalable in that an already assembled base modular structure may be expanded by adding additional modular panels. For example, the base modular structure is assembled as three compartments in a single row creating a one by three base modular structure. Each compartment is a section of the modular structure that is divided from each other compartment of the modular structure by modular panels, i.e. a first side panel, a second side panel, a roof panel, and a floor panel. Three additional compartments in a second single row adjacent to the original three compartments are then added to the base modular structure. Thus, the scaled modular structure now includes six compartments dispersed in a two by three modular structure.
The panel joining assembly is implemented in joining each modular panel of the modular structure together. The panel joining assembly traps a shear pin inside a gasket that joins adjacent modular panels to substantially prevent moisture from intruding into the modular structure while providing a fitting tolerance between each adjacent modular structure that provides ease in assembly. The fitting tolerance between each adjacent module structure provides flexibility in aligning the modular structures so that each modular structure is not required to be directly aligned with each other modular structure. For ease of discussion, the joining technique implemented between modular panels will simply be referred to as the panel joining assembly.
In order to further improve upon the moisture tightness of the modular structure, a base modular structure includes three compartments joined together in a single row forming a bay. A bay is the minimum amount of modular panels required to standalone as a modular structure. The roof of the center compartment overlaps each roof of each of the two adjacent compartments to the center compartment. For ease of discussion, the roof of the center compartment overlapping each roof of each of the two adjacent compartments will be simply referred to as the upper roof while each roof of the two adjacent compartments will be simply referred to as the lower roofs. In the overlap region, a gasket is placed between the upper roof and the lower roof. A metal sleeve is inserted through the lower roof, the gasket and the upper roof in the overlap region. A bolt that may be self-aligned is inserted through the metal sleeve and tightened to compress the lower roof, the gasket, and the upper roof together forming a seal. The metal bolt confines the bolt and resists the shear load induced on the modular structure due to lateral racking. For ease of discussion, the joining technique implemented in the overlapping portion of the upper roof and each of the lower roofs will be simply referred to as the roof joining assembly. The overlapping of the upper roof and the lower roofs provides a path for moisture to run off of the roof of the modular structure rather than accumulating on the roof.
As the following description will show in detail, the disclosed invention takes advantage of these properties to protect the inside of the modular structure from moisture while providing ease in assembly. This serves to improve the overall performance of the modular structure, particularly in applications that require rapid assembly while being exposed to severe environmental conditions. In the description that follows, even though references may be made to use in military applications or as a PTM, it should be understood that the system and method apply to a wide variety of applications that may require a modular structure with rapid assembly and adequate protection for personnel and/or equipment stored within. For example, the system and method may find use in aid relief in the aftermath of natural disasters.
FIG. 1 depicts an example modular structure 100. The example modular structure 100 includes a first bay 110a, a second bay 110b, and a third bay 110c. Each bay 110a through 110c includes compartments positioned in a row to form each respective bay 110a through 110c. The first bay 110a includes compartments 120a, 120b, and 120c. The second bay 110b includes compartments 120d, 120e, and 120f. The third bay includes compartments 120g, 120h, and 120i. Thus, the example modular structure 100 includes nine total compartments 120a through 120i arranged in three bays 110a through 110c as depicted in a three compartment by three compartment configuration.
As noted above, the modular structure is assembled as a base modular structure and then is scalable so that additional modular structures may be added until the final modular structure is reached. Regarding the example modular structure 100, the example modular structure 100 is initially assembled by formulating three compartments into a single bay. After the modular structure 100 is initially formulated into the single bay, then the modular structure 100 is a base modular structure and may stand alone. No additional compartments and/or bays are required to be added to the base modular structure of the example modular structure 100 for the base modular structure to adequately protect personnel and/or equipment housed within the base modular structure. However, additional bays may be then added to the base modular structure in order to increase the size of the example modular structure 100.
For example, the example modular structure 100 is formulated by initially assembling compartments 120d, 120e, and 120f into the second bay 110b forming the base modular structure. After the second bay 110b is assembled as the base modular structure, the second bay 110b may stand alone without any additional compartments to adequately protect personnel and/or equipment housed within the second bay 110b. However, to increase the size of the example modular structure 100, the example modular structure 100 is scaled in that the compartments 120a, 120b, and 120c are formulated to assemble the first bay 110a and the compartments 120g, 120h, and 120i are formulated to assemble the third bay 110c. Rather than being a single bay as depicted by the second bay 110b, the example modular structure 100 has been scaled to increase in size to also include the first bay 110a and the third bay 110c. 
Although, the base modular structure for the example modular structure 100 is depicted as a single bay that is formulated by three compartments positioned in a row in FIG. 1, the base modular structure for the example modular structure 100 may be scaled to include any quantity of bays each with three compartments positioned so that the example modular structure 100 is three compartments across with any quantity of bays deep that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure.
As noted above, in order to improve upon the moisture tightness of the example modular structure 100, each bay 110a through 110c includes an upper roof 125a through 125c that overlaps adjacent lower roofs 130a through 130f. For example, the first bay 110a includes upper roof 125a that overlaps adjacent roofs 130a and 130b. The second bay 110b includes upper roof 125b that overlaps adjacent roofs 130c and 130d. The third bay 110c includes upper roof 125c that overlaps adjacent roofs 130e and 130f. 
The overlapping of upper roofs 125a through 125c over adjacent lower roofs 130a through 130f provides a path for moisture to run off of the roof of the example modular structure 100 rather than accumulating on the roof. The higher positioning of the upper roofs 125a through 125c in the center of the example modular structure 100 relative the lower positioning of the adjacent roofs 130a through 130f on the sides of the example modular structure 100 provides a slope. The slope provides a pathway for water accumulating on the higher positioned upper roofs 125a through 125c to flow down to the lower positioned adjacent roofs 130a through 130f and then off of the roof of the example modular structure 100 altogether.
Each roof joining assembly 140a through 140f positioned in the overlapping portion of each upper roof 125a through 125c and each adjacent lower roof 130a through 130f also substantially prevents moisture from entering the example modular structure 100. As noted above, each roof joining assembly 140a through 140f includes a gasket positioned in the overlap region between each upper roof 125a through 125c and each lower roof 130a through 130f. Each upper roof 125a through 125c, each gasket, and each lower roof 130a through 130f are then bolted together to form a seal that substantially precludes moisture from entering the inside of the example modular structure 100. Further, each upper roof 125a through 125c conceals each roof joining assembly 140a through 140f to limit the amount of moisture that each roof joining assembly 140a through 140f is exposed to so that the material properties of each roof joining assembly 140a through 140f are preserved further increasing the performance of each in excluding moisture.
Further, in order to improve upon moisture tightness of the example modular structure 100, each adjacent modular panel included in the example modular structure 100 may be joined via panel joining assembly 170a through 170n. Each panel joining assembly 170a through 170n also includes shear pins trapped inside a gasket that joins each adjacent modular structure to formulate a seal that substantially excludes moisture from entering the inside of the example modular structure 100. For example in examining compartments 120c, 120f, and 120i, the lower roof 130d of compartment 120f is structurally joined to the lower roof 130b of compartment 120c via panel joining assembly 170i. The lower roof 130d of compartment 120f is structurally joined to the lower roof 130f of compartment 120i via panel joining assembly 170j. The side wall 160b of compartment 120f is structurally joined to the side wall 160c of compartment 120i via panel joining assembly 170c. 
End panels 180a through 180f provide the end structures for the example modular structure 100. A first set of end panels for the example modular structure 100 include a passage way into the example modular structure as depicted by end panels 180a, 180b, and 180c that include doors 150a, 150b, and 150c, respectively. Doors 150a, 150b, and 150c provide entryways into the example modular structure 100 for personnel to easily enter and/or exit the example modular structure 100. A second set of end panels enclose the example modular structure 100 on an opposite end from the example modular structure as the first set of end panels as depicted by end panels 180d, 180e, and 180f. 
Examples of the modular panels included in the example modular structure 100 as shown in FIG. 1 include the upper roofs 125a through 125c, the lower roofs 130a through 130f, side panels 160a through 160c, and end panels 180a through 180f. The structural materials of the modular panels that are assembled to form the example modular structure 100 may include but are not limited to concrete, metal, composite material, wood, fiberglass, steel, aluminum, and/or any other structurally viable material sufficient to protect the personnel and/or equipment housed inside the example modular structure 100 that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure.
The example modular structure 100 may be erected on land, offshore platforms, ship decks, amphibious vehicles, land vehicles, aerial platforms, aerial vehicles, and/or any other type of surface that is capable of supporting the example modular structure 100 that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure. The example modular structure 100 may be constructed using exclusively manpower without the assistance of machines such as a crane and/or forklift, using exclusively machines such as a crane and/or forklift, any combination thereof, and/or any other type of construction methods that can be executed in an efficient manner that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure.
Each of the modular panels and parts required to assemble the example modular structure 100, which includes but is not limited to the upper roofs 125a through 125c, the lower roofs 130a through 130f, the side walls 160a through 160c, the doors 150a through 150c, and the roof joining assembly 140a through 140f, may be packed into a transferable kit that enables the modular panels and parts to be easily transferred to the location that the example modular structure 100 is to be assembled. Each of the modular panels may be substantially flat without any extruding objects and/or pieces to so that the each of the modular panels may be easily stowed and packed into the transferable kit.
The modular panels and parts included in the example modular structure 100 are interchangeable, which increases the ease of assembly. For example, the lower roof 130a located on the compartment 120a can also be placed on the compartment 120i where the lower roof 130f is currently depicted in FIG. 1. Further, aluminum sheets may be attached to each modular panel relative to the inside of the example modular structure 100 to provide fire resistance to fires external to the example modular structure 100. Although aluminum is implemented, any type of fire resistant material may also be implemented that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure. Further, the modular panels may be constructed with a corrosion-resistant composite material to prevent corrosion. Although a corrosion-resistant composite material is implemented, any type of corrosion-resistant material may also be implemented that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure.
The following discussion below regarding FIGS. 2A through 7B discloses in detail how an example modular structure 100 may be rapidly assembled according to an exemplary embodiment of the present disclosure. The present disclosure is not limited to this operational description as disclosed in FIGS. 2A through 7B. Rather, it will be apparent to persons skilled in the relevant art(s) from the teaching herein that other methods of rapid assembly are within the scope of the present disclosure.
Referring to FIG. 2A, in which like reference numerals are used to refer to like parts, a floor gasket configuration 200 is shown. The floor gasket configuration 200 includes a plurality of floor gaskets 210a through 210n where n is an integer equal to or greater than one. The plurality of floor gaskets 210a through 210n is placed on a surface that the example modular structure 100 is to be erected on. As noted above, the surface for the example modular structure 100 may include but is not limited to a ship deck such as the deck of a hovercraft, land, etc. Often times the surface that the example modular structure 100 is to be erected on is not flat and/or level but rather includes deflections. Simply erecting the example modular structure 100 on a deflected surface may weaken the overall support of the example modular structure 100. The plurality of floor gaskets 210a through 210n absorbs any surface deflections the example modular structure 100 may be erected on and as a result provides stability to the example modular structure 100.
Referring to FIG. 2B, in which like reference numerals are used to refer to like parts, a floor configuration 220 is shown. The floor configuration 220 includes a center floor panel 230, a first side floor panel 240, and a second side floor panel 250. The center floor panel 250 includes a top surface 232, a first side edge 234a, a second side edge 234b, a third side edge 234c, a fourth side edge 234d, and a bottom surface 238. The first side floor panel 240 includes a top surface 242, a first side edge 244a, a second side edge 244b, a third side edge 244c, a fourth side edge 244d, a bottom surface 248, and a groove 262. The second side floor panel 250 includes a top surface 252, a first side edge 254a, a second side edge 254b, a third side edge 254c, a fourth side edge 254d, a bottom surface 258, and a groove 264.
The bottom surface 238 of the center floor panel 230 is positioned on the plurality of floor gaskets 210a through 210n so that the bottom surface 238 of the first side edge 234a and the third side edge 234c of the center floor panel 230 are placed onto an individual floor gasket 210a through 210n. For example, the first side edge 234a of the center floor panel 230 is placed onto the floor gasket 210b while the third side edge 234c is placed onto the floor gasket 210c. The center floor panel 230 is to act as the center floor panel for a bay included in the example modular structure 100. For example, the center floor panel 230 is the center floor panel in the second bay 110b in that the center floor panel 230 is the floor panel for the compartment 120e. 
The first side floor panel 240 is positioned on the plurality of floor gaskets 210a through 210n adjacent to the center floor panel 230. For example, the third side edge 244c of the first side floor panel 240 is positioned adjacent to the first side edge 234a of the center floor panel 230. A bottom surface 248 of the first side floor panel 240 is positioned on the plurality of floor gaskets 210a through 210n so that the bottom surface 248 of the first side edge 244a and the third side edge 244c of the first side floor panel 240 are placed onto an individual floor gasket 210a through 210n. For example, the first side edge 244a is placed onto the floor gasket 210a while the third side edge 244c is placed onto the floor gasket 210b. 
The second side floor panel 250 is positioned on the plurality of floor gaskets 210a through 210n adjacent to the center floor panel 230 on the opposite side of the center floor panel 230 from the first side floor panel 240. For example, the first side edge 254a of the second side floor panel 250 is positioned adjacent to the third side edge 234c of the center floor panel 230. A bottom surface 258 of the second side floor panel 250 is positioned onto the plurality of floor gaskets 210a through 210n so that the bottom surface 258 of the first side edge 254a and the third side edge 254c of the second side floor panel 250 are placed onto an individual floor gasket 210a through 210n. For example, the first side edge 254a is placed onto the floor gasket 210c while the third side edge 254c is placed onto the floor gasket 210n. 
The first and second side floor panels 240 and 250 are to act as the side floor panels for a bay included in the example modular structure 100. For example, the first side floor panel 240 is the side floor panel in the second bay 110b in that the first floor panel 240 is the floor panel for the compartment 120f. The second side floor panel 250 is the floor panel in the second bay 110b in that the second side floor panel 250 is the floor panel for the compartment 120d. 
The first side floor panel 240 is joined to the center floor panel 230 via panel joining assembly 260a. The second side floor panel 250 is joined to the center side floor panel 230 via panel joining assembly 260b. As noted above, each modular panel included in the example modular structure 100 is joined via the panel joining assembly as shown with the panel joining assemblies 170a through 170n in FIG. 1. Panel joining assemblies 260a and 260b shown in FIG. 2B are substantially similar to the panel joining assemblies 170a through 170n in FIG. 1.
Referring to FIG. 2C, in which like reference numerals are used to refer to like parts, an example structural joining configuration 270 is shown. The structural joining configuration 270 depicts the joining of the central floor panel 230 to the second side floor panel 250 via panel joining assembly 260b. The panel joining assembly 260b includes a gasket 274 and a plurality of shear pins 278a through 278c. 
Referring to FIG. 2D, in which area 2D of FIG. 2C is enlarged and in which like reference numerals are used to refer to like parts, the structural joining assembly 260b is shown. Shear pin 278a is trapped in the gasket 274 in that a first end 280a of the shear pin 278a protrudes through a first side 282a of the gasket 274 and a second end 280b of the shear pin 278 protrudes through the second side 282b of the gasket 274. The gasket 274 may be made of a silicon material with substantial thickness and low durometer and/or any other material with characteristics that may provide a substantial seal to moisture that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure.
In an embodiment, the shear pins 278a through 278c pass substantially through the gasket 274 so that the first end 280a and the second end 280b of the shear pins 278a through 278c are joined. In another embodiment, the shear pins 278a through 278c do not pass substantially through the gasket 274 so that the first end 280a and the second end 280b of the shear pins 278a through 278c are not joined but rather have a portion of the gasket 274 in between each. In another embodiment, the shear pins 278a through 278c include a single piece of material joining the first end 280a and the second end 280b. In another embodiment, the shear pins 278a through 278c include segmented pieces of material joining the first end 280a and the second end 280b. The shear pins 278a through 278c may include any type of structure that can be trapped in the gasket 274 so that the first end 280a and the second end 280b protrude outward away from the gasket 274 that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure.
Returning to FIG. 2C, the central floor panel 230 includes a plurality of bores 270a through 270l positioned on each side edge 234a through 234d of the central floor panel 230. For example, bores 270d through 270f are positioned on the third side edge 234c. The second end 280b of each shear pin 278a through 278c is placed into the corresponding bore 270d through 270f positioned on the third side edge 234c so that the gasket 274 is fitted onto the third side edge 234c. For example, the second end 280b for shear pin 278a is placed into bore 270f. The second end 280b for shear pin 278b is placed into bore 270e. The second end 280b for shear pin 278c is placed into bore 270d. 
The second side floor panel 250 includes a plurality of bores 276a through 276h positioned on the first side edge 254a, the second side edge 254b, and the fourth side edge 254c of the second side floor panel 250. For example, bores 276g through 276i are positioned on the first side edge 254a. The first end 280a of each shear pin 278a through 278c is placed into the corresponding bore 276g through 276i positioned on the first side edge 254a so that the gasket 274 is fitted onto the first side edge 254a. For example, the first end 280a for shear pin 278a is placed into bore 276g. The first end 280a for shear pin 278b is placed into bore 276h. The first end 280a for shear pin 278c is placed into bore 276i. 
After the gasket 274 is fitted onto both the third side edge 234c of the central floor panel 230 and the first side edge 254a of the second side floor panel 250 as outlined above, the central floor panel 230 and the second side floor panel 250 are compressed together to trap each shear pin 278a through 278c within the gasket 274. As a result, the central floor panel 230 is joined to the second side floor panel 250 via the each corresponding shear pin 278a through 278c trapped inside the gasket 274 forming a substantially moisture tight seal between the central floor panel 230 and the second side floor panel 250. The substantially moisture tight seal substantially prevents moisture from entering the example modular structure 100 between the central floor panel 230 and the second side floor panel 250.
The panel joining assembly 260a may be formed between the central floor panel 230 and the first side floor panel 240 may be formed in a similar fashion as the panel joining assembly 260b explained above. Further, the panel joining assemblies 170a through 170n formed between adjacent modular structures included in the example modular structure 100 in FIG. 1 are likewise formed in a similar fashion as the panel joining assembly 260b explained above. For example, as shown in FIG. 2C, a panel joining assembly (not shown) similar to that of the gasket 274 and shear pin 278a through 278c configuration depicting the panel joining assembly 260b may be used to join the second side edge 234b of the central floor panel 230 to a side edge (not shown) of a second central floor panel (not shown) in forming another bay (not shown) to the bay (not shown) that includes the central floor panel 230.
Each modular panel included in the example modular structure 100 in FIG. 1 may include any quantity of bores positioned on each side of each modular structure necessary to form a substantially moisture tight seal by the panel joining assemblies 170a through 170n that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure. Further, each panel joining assembly 170a through 170n may include any quantity of shear pins necessary to form a substantially moisture tight seal between adjacent modular panels that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure.
Referring to FIG. 3, in which like reference numerals are used to refer to like parts, an end panel configuration 300 is shown. A first end panel 310 includes a first side edge 312a, a second side edge 312b, a third side edge 312c, a fourth side edge 312d, an outer portion 314 that faces the outside of the eventual modular structure, an inner portion 316 that faces the inside of the eventual modular structure, and a door 318. A second end panel 320 includes a first side edge 322a, a second side edge 322b, a third side edge 322c, a fourth side edge 322d, an outer portion 324 that faces the outside of the eventual modular structure, an inner portion 326 that faces the inside of the eventual modular structure, and a door 328.
First end panel 310 is positioned onto central floor panel 230 and second end panel 320 is positioned onto second side floor panel 250. The first and second end panels 310 and 320 are to act as the end panels for a bay included in the example modular structure 100. For example in FIG. 1, the first end panel 310 is the end panel 180b. The second end panel 320 is the end panel 180c. The first end panel 310 and the second end panel 320 include a passage way into the eventual modular structure being formed with doors 318 and 328. Although the first end panel 310 and the second end panel 320 are depicted as passage ways, the first end panel 310 and the second end panel 320 may also enclose the eventual modular structure being formed similar to the end panels 180d through 180f of the example modular structure 100.
The third side edge 312c of the first end panel 310 is joined to the fourth side edge 234d of the central floor panel 230 via panel joining assembly 330a. The third side edge 322c of the second end panel 320 is joined to the fourth side edge 254d of the second side floor panel 250 via panel joining assembly 330b. The fourth side edge 312d of the first end panel 310 is joined to the second side edge 322b of the second end panel 320 via panel joining assembly 330c. The panel joining assemblies 330a through 330c are substantially similar to the structural joining assembly 260b discussed in greater detail above.
Referring now to FIG. 4A, in which like reference numerals are used to refer to like parts, a divider panel configuration 400 is shown. A first divider panel 410 includes a first side edge 412a, a second side edge 412b, a third side edge 412c, and a fourth side edge 412d. The first divider panel 410 is positioned onto central floor panel 230 and second floor end panel 250. The first divider panel 410 is positioned onto the first end panel 310 and the second end panel 320. The first divider panel 410 provides support for a bay included in the example modular structure 100. After the first divider panel 410 is installed in relation to the central floor panel 230, the second end floor panel 320, the first end panel 310, and the second end panel 320 as mentioned above, the divider panel configuration 400 may stand alone without any external support as the assembly of the structure is continued. For example, the divider panel configuration 400 may no longer require being physically held up by personnel assembling the structure after the divider panel 410 is installed.
Because the first divider panel 410 is substantially positioned internal to the divider panel configuration 400, structural joining assemblies such as panel joining assembly 260b as discussed in detail above, are not required for modular panels adjacent to the first divider panel 410. The first divider panel 410 is not exposed to moisture external to the divider panel configuration 400 and thus does not require the panel joining assemblies. For example, a structural joining assembly is not required between the first divider panel 410 and the central floor panel 230 and the second floor end panel 250. A structural joining assembly is also not required between the first divider floor panel 410 and the first end panel 310 and the second end panel 320. Rather, the first divider panel 410 is bolted into the central floor panel 230 and the second floor end panel 250. The first divider panel 410 is also bolted into the first end panel 310 and the second end panel 320. The first divider panel 410 is modular in that it is interchangeable with any other divider panel associated with the example modular structure 100.
Referring to FIG. 4B, in which like reference numerals are used to refer to like parts, a detailed divider panel configuration of encircled area 4B taken from FIG. 4A is shown. The third side edge 412c of the first divider panel 410 is divided into a first bottom edge 420 and a second bottom edge 430. Dividing line 425 depicts where the first side edge 254a of the second end floor panel 250 is joined to the third side edge 234c of the center floor panel 230. The first bottom edge 420 is positioned adjacent to the first side edge 254a of the second end floor panel 250 while the second bottom edge 430 is positioned adjacent to the third side edge 234c of the center floor panel 230. The first bottom edge 420 is bolted into a blind insert (not shown) located in the first side edge 254a of the second end floor panel 250 via bolt 450a while the second bottom edge 430 is bolted into a blind insert (not shown) located in the third side edge 234c of the center floor panel 230 via bolt 450b. In an embodiment, a pin rod may be used to align each bolt 450a and 450b with each corresponding blind insert.
The first divider panel 410 is also divided into a first side edge 460 and a second side edge 470. Dividing line 440 depicts where the second side edge 322b (refer to FIG. 3) of the second end panel 320 is joined to the fourth side edge 312d of first end panel 310 (see also FIG. 3). The first side edge 460 is positioned adjacent to the second side edge 322b (refer to FIG. 3) of the second end panel 320 while the second side edge 470 is positioned adjacent to the fourth side edge 312d of the first end panel 310. The first side edge 460 is bolted into a blind insert (not shown) located in the second side edge 322b (refer to FIG. 3) of the second end panel 320 via bolt 455b while the second side edge 470 is bolted into a blind insert (not shown) located in the fourth side edge 312d of the first end panel 310 via bolt 455a. The pin rod may be used to align bolt 455a or 455b into each respective blind insert. For example, a pin rod is inserted into the blind insert corresponding to bolt 455a. The insertion of the pin rod into the blind insert aligns bolt 455b to its corresponding blind insert so that the bolt 455b may bolted into its corresponding blind insert. After bolt 455b is bolted into its corresponding blind insert, the pin rod is removed from the blind insert corresponding to bolt 455a and bolt 455a is then bolted in to its corresponding blind insert.
Referring now to FIG. 5, in which like reference numerals are used to refer to like parts, a side panel configuration 500 is shown. Third end panel 510 may be installed in a similar fashion as first end panel 310 and second end panel 320 as discussed in detail above. The third end panel 510 includes a first side edge 512a, a second side edge 512b, a third side edge 512c, a fourth side edge 512d, and a door 518. A second divider panel 520 may be installed in a similar fashion as the first divider panel 410 as discussed in detail above. The second divider panel 520 includes a first side edge 522a, a second side edge 522b, a third side edge 522c, and a fourth side edge 522d. A first side panel 530 includes a first side edge 532a, a second side edge 532b, a third side edge 532c, a fourth side edge 532d. A second side panel 540 includes a first side edge 542a, a second side edge 542b, a third side edge 542c, a fourth side edge 542d. 
First side panel 530 is positioned onto first side floor panel 240 and third end panel 510. Second side panel 540 is positioned onto second side floor panel 250 and second end panel 320. The first and second side panels 530 and 540 are to act as the side panels for a bay included in the example modular structure 100. For example in FIG. 1, the first side panel 530 is the side panel 160a in bay 110a. 
The third side edge 532c of the first side panel 530 is placed into groove 262 of the first side floor panel 240 joining the third side edge 532c of the first side panel 530 to the first side edge 244a of the first side floor panel 240 with a tongue and groove joining assembly. The tongue and groove joining assembly also substantially prevents moisture from entering the example modular structure 100 similar to that of the roof joining assembly 140a through 140f and the panel joining assembly 170a through 170n. The second side edge 532b of the first side panel 530 is joined to the second side edge 512b of the third end panel 510 via panel joining assembly 550a. The panel joining assembly 550a is substantially similar to the panel joining assembly 260b discussed in greater detail above.
The third side edge 542c of the second side panel 540 is placed into groove 264 of the second side floor panel 250 joining the third side edge 542c of the second side panel 540 to the third side edge 254c of the second side floor panel 250 with a tongue and groove joining assembly. The second side edge 542b of the second side panel 540 is joined to the fourth side edge 322d of the second end panel 320 via panel joining assembly 550b. The structural joining assembly 550b is substantially similar to the structural joining assembly 260b discussed in greater detail above. The first side panel 530 and the second side panel 540 are modular in that each are interchangeable with each other and any other side panel associated with the example modular structure 100.
Referring now to FIG. 6A, in which like reference numerals are used to refer to like parts, a lower roof panel configuration 600 is shown. A first lower roof panel 610 includes a top surface 612 and a bottom surface 614. The first lower roof panel 610 further includes a first top side edge 616a, a second top side edge 616b, a third top side edge 616c, and a fourth top side edge 616d. The first lower roof panel 610 further includes a first bottom side edge 618a, a second bottom side edge 618b, a third bottom side edge 618c, and a fourth bottom side edge 618d. The first lower roof panel 610 further includes a first side edge 620a, a second side edge 620b, a third side edge 620c, and a fourth side edge 620d. The first lower roof panel 610 further includes a first set of bores 622a, 622b, and 622c located on the fourth side edge 618d. The first lower roof panel 610 further includes a second set of bores 624a, 624b, and 624c located on the third top side edge 616c that go through to the third bottom side edge 618c, which will be used to join the first lower roof panel 610 to the upper roof panel 710, described later with reference to FIG. 7B. The first lower roof panel 610 further includes brackets 626a and 626b. Bracket 626a includes first bracket portion 630a and second bracket portion 630b. Bracket 626b includes first bracket portion 632a and second bracket portion 632b. The first lower roof further includes metal strips 628a and 628b. The brackets 626a and 6262b and the metal strips 628a and 628b will be discussed in detail below with reference to FIG. 8. The first lower roof panel 610 further includes a groove 634.
Referring now to FIG. 6B, in which like reference numerals are used to refer to like parts, a lower panel roof configuration 660 is shown. The first lower roof panel 610 is positioned onto the third side panel 530 and the third end panel 510. The first lower roof panel 610 is to act as the lower roof panel for a bay included in the example modular structure 100. For example in FIG. 1, the first lower roof panel 610 is the lower roof panel 130a in bay 110a. 
The groove 634 of the first lower roof panel 610 is placed onto the first side edge 532a of the first side panel 530 joining the bottom side edge 618a of the first lower roof panel 610 to the first side edge 532a of the first side panel 530 with a tongue and groove joining assembly. The fourth side edge 620d of the first roof panel 610 is joined to the first side edge 512a of the third end panel 510 via panel joining assembly 670a. The panel joining assembly 670a is substantially similar to the panel joining assembly 260b discussed in greater detail above. The bottom side edge 618c of the first roof panel 610 is placed onto the first side edge 522a of the second divider panel 520 so that the bottom side edge 618c of the first lower roof panel 610 is flush to the first side edge 522a of the second divider panel 520. The joining of the bottom side edge 618c of the first lower roof panel 610 to the first side edge 522a of the second divider panel 520 will be discussed in further detail below with reference to FIG. 6B. The second lower roof panel 640 is assembled in a manner similar to the first lower roof panel 610 discussed in detail above with reference to FIG. 6B.
Referring now to FIG. 7A, in which like reference numerals are used to refer to like parts, an upper roof panel configuration 700 is shown. An upper roof panel 710 includes a top surface 712, a bottom surface 714, a first bottom side edge 716a, a second bottom side edge 716b, a third bottom side edge 716c, a fourth bottom side edge 716d, a first side edge 718a, a second side edge 718b, a third side edge 718c, and a fourth side edge 718c. The upper roof panel 710 is positioned onto the first lower roof panel 610 and the second lower roof panel 640. The upper roof panel 710 is also joined to the first end panel 310. The upper roof panel 710 acts as the upper roof panel for a bay included in the example modular structure 100. For example in FIG. 1, the upper roof panel 710 is the upper roof panel 125a in bay 110a. 
The first bottom side edge 716a of the upper roof panel 710 is positioned onto the third top side edge 616c of the first lower roof panel 610. The first bottom side edge 716a of the upper roof panel 710 overlaps the third top side edge 616c of the first lower roof panel 610 via a roof joining assembly 720a that provides a substantially moisture tight seal substantially preventing moisture from entering the example modular structure 100. Further, the overlapping of the first bottom side edge 716a of the upper roof panel 710 over the third top side edge 616c of the first lower roof panel 610 provides a pathway for water to run off from the upper roof panel 710 down to the first lower roof panel 610 and then off of the example modular structure 100 onto the ground. The water pathway results from the elevated first upper roof panel 710 relative to the first lower roof panel 610 so that the water flows downward from the upper roof panel 710 to the first lower roof panel 610. The roof joining assembly 720a is substantially similar to the roof joining assembly depicted by the first structural joining assemblies 140a through 140f for the example modular structure 100. The roof joining assembly 720a will be discussed in further detail below in FIG. 7B. The upper roof panel 710 is positioned onto the second lower roof panel 640 in a similar fashion as the upper roof panel 710 positioned onto the first lower roof panel 610 discussed in detail above.
The third side edge 718d of the upper roof panel 710 is joined to the first side edge 312a of the first end panel 310 via panel joining assembly 730. The panel joining assembly 730 is substantially similar to the panel joining assembly 260b discussed in greater detail above.
Referring now to FIG. 7B, in which like reference numerals are used to refer to like a parts, a detailed structural joining assembly 750 is shown. As noted above, the third bottom side edge 618c of the first lower roof panel 610 is positioned onto the top side edge 522a of the second divider panel 520 so that the bottom side edge 618c of the first lower roof panel 610 is flush to the top side edge 522a of the second divider panel 520. A metal sleeve 760 is placed through a first opening 752a of a bore 756 located in the top side edge 522a of the second divider panel 520 and goes through a second opening 752b of the bore 756. The metal sleeve 760 continues through the second bore 624c located in the third bottom side edge 618c of the first lower roof panel 610 and continues through to the third top side edge 616c of the first lower roof panel 610. The remaining portion of the metal sleeve 760 is external to the third top side edge 616c of the first lower roof panel 610. The metal sleeve 760 aligns second divider panel 520 with the first lower roof panel 610.
A gasket 758 includes a bore 764 with a first opening 762a and a second opening 762b. The first opening 762a of the bore 764 is located on a bottom surface 766 of the gasket 758 while the second opening 762b of the bore 764 is located on a top surface 768 of the gasket 758 so that the bore 764 passes from the top surface 768 of the gasket 758 through the gasket 758 to the bottom surface 766 of the gasket 758. The gasket 758 is positioned onto the third top side edge 616c of the first lower roof panel 610. The first opening 762a of the bore 764 is placed on the metal sleeve 760 so that the metal sleeve 760 goes through the first opening 762a of the bore 764 through the bore 764 and out the second opening 762b of the bore 764 so that the metal sleeve 760 goes through the gasket 758. The remaining portion of the metal sleeve 760 is external to the top surface 768 of the gasket 758. The metal sleeve 760 aligns the second divider panel 520 with the first lower roof panel 610 with the gasket 758.
The first bottom side edge 716a of the upper roof panel 710 is then positioned onto the top surface 768 of the gasket 758. A bore 774 located in the first bottom side edge 716a of the upper roof panel 710 includes a first opening 770, an end stop 776. A fastener 775 located at the end stop 776 of the bore 774 includes a threaded portion 778 and a threaded end stop 772. The first opening 770 of the bore 774 is placed on the metal sleeve 760 so that metal sleeve 760 goes through the first opening of the bore 774 and terminates at the end stop 776 of the bore 774. The metal sleeve 760 aligns the second divider panel 520 with the first lower roof panel 610 with the gasket 758 with the upper roof panel 710.
A bolt 754 is then inserted into the metal sleeve 760 so that the bolt passes through the second divider panel 520, the first lower roof panel 610, the gasket 758 and into the bore 774 located in the first bottom side edge 716a of the upper roof panel 710 so that the bolt 754 reaches the threaded portion 778 of the fastener 775. The bolt 754 is then tightened so that the bolt 754 engages the threaded portion 778 of the fastener 775 until the bolt 754 reaches the threaded end stop 772 of the fastener 775. The tightening of the bolt 754 until the bolt reaches the threaded end stop 772 of the fastener 775 also tightens the second divider panel 520, the first lower roof panel 610, the gasket 758, and the upper roof panel 710 together forming the roof joining assembly 720a. The tightening of the second divider panel 520, the first lower roof panel 610, the gasket 758, and the upper roof panel 710 together via bolt 745 creates a substantially moisture tight seal substantially protecting the inside of the example modular structure 100 from moisture. Further, the description of the metal sleeve 760 discussed above provides a self-alignment mechanism so that the bolt 754 is easily inserted through the divider panel 520, the first lower roof panel 610, the gasket 758, and the upper roof panel 710 so that the bolt 754 may be tightened to form the substantially moisture tight seal. The overlapping of the upper roof panel 710 with the first lower roof panel 610 discussed above may be seen by overlapping portion 780.
Returning briefly to FIG. 7A, after the upper roof panel 710 has been joined to the first lower roof panel 610 via the roof joining assembly 720a, the second lower roof panel 640 via the roof joining assembly 720b, and the first end panel 310 via the panel joining assembly 730, openings 735a through 735c remain in the upper roof panel configuration 700. End panels (not shown) may be placed in each opening 735a through 735c and joined to the existing upper roof panel configuration 700 via panel joining assemblies substantially similar to the panel joining assembly 264a discussed in detail above. The joining of the end panels (not shown) to the existing roof panel configuration 700 may complete the existing upper roof panel configuration 700 into a single bay that may stand alone without any further bays added.
Rather than adding additional end panels (not shown), the existing upper roof panel configuration 700 may be extended to include a second bay (not shown). A center floor panel (not shown), first side floor panel (not shown), and a second side floor panel (not shown) may be joined to the existing upper roof panel configuration 700 and the above discussion may be repeated to form a second bay. For example, the existing upper roof panel configuration 700 may represent the first bay 110a in the example modular structure 100. A second bay 110b may then be assembled to the first bay 110a in a similar fashion as the discussion above.
Referring now to FIG. 8, in which like reference numerals are used to refer to like parts, an example modular structure 800 is shown. The example modular structure 800 shares many similar features with the example modular structure 100; therefore only differences between the example modular structure 100 and the example modular structure 800 are to be discussed in further detail. The example modular structure 800 includes brackets 626a, 626b, 656a, 656b, and 810a through 810h. The example modular structure 800 also includes chain supports 820a through 820g; deck anchors 830a through 830g; metal strips 628a, 628b, 658a, 658b, and 840a through 840h; and ratchet straps 850e through 850g. 
The example modular structure 800 is secured to the deck that the example modular structure 800 is constructed upon, such as a hovercraft deck for example, by chain supports 820a through 820g. Each chain support 820a through 820g is connected to a corresponding bracket 626a, 626b, 656a, 656b, and 810a through 810h. Each chain support 820a through 820g is also connected to each corresponding deck anchor 830a through 830g. For example, chain 820a is hooked into the second bracket portion 632b of bracket 626b and chain 820b is hooked into the second bracket portion 630b of bracket 626a. Chain 820 is also hooked into the deck anchor 830a and chain 820b is hooked into deck anchor 830b. The hooking of the chain 820a from the second bracket portion 632b of bracket 626b to the deck anchor 830a and the hooking of the chain 820b from the second bracket portion 630b to the deck anchor 830b secures the example modular structure 800 to the deck that the example modular structure 800 is constructed upon.
Any force applied to the example modular structure 800 is not sustained by the example modular structure 800. Rather, each received force is transferred in a fashion discussed in detail below so that example modular structure 800 is protected from such received forces. A force transferring configuration is formulated by connecting a metal strip to a corresponding bracket to a corresponding chain to a corresponding deck anchor. For example, metal strip 628a is connected to bracket 626b which is connected to chain 820a which is connected to deck anchor 830a forming a force transferring configuration. A force applied to the example modular structure 800 is received by the metal strip 628a. Because of the connection of the metal strip 628a to the bracket 626b, the force is then transferred from the metal strip 628a to the bracket 626b. Because of the connection of the bracket 626b to the chain 820a, the force is then transferred from the bracket 626b to the chain 820a. Because of the connection of the chain 820a to the deck anchor 830a, the force is then transferred from the chain 820a to the deck anchor 830a. Thus, the example modular structure 800 is protected from the force.
Referring briefly to FIG. 6A, in an embodiment, the bracket 626b is positioned on the first top side edge 616a of the first lower roof panel 610. The first bracket portion 632a of the bracket 626b is bolted to the first top side edge 616a of the first lower roof panel 610 while the second bracket portion 632b is free from the first lower roof panel 610 to connect to the chain 820a. The metal strip 628a is positioned internal to the first lower roof panel 610 so that the metal strip 628a is positioned in between the top surface 612 of the first lower roof panel 610 and the bottom surface 614 of the first lower roof panel 610. In another embodiment, the first bracket portion 632a of the bracket 626b is also internal to the first lower roof panel 610 so that the first bracket portion 632a of the bracket 626b is also positioned in between the top surface 612 of the first lower roof panel 610 and the bottom surface of the first lower roof panel 610. In such an embodiment, the first bracket portion 632b is directly connected to the metal strip 628a. The bracket 626b and the metal strip 628a may be arranged in any configuration that sufficiently transfers any force received by the metal strip 628a to the bracket 626b that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure.
Referring back to FIG. 8, the example modular structure 800 is clamped with a plurality of ratchet straps that includes ratchet straps 850a and 850b among other ratchet straps not shown. The plurality of ratchet straps include 850a and 850b may include strapping mechanisms such as but not limited to a hook assembly, ratchet pullers, turnbuckles, and/or any other strapping mechanism that will clamp the modular structure 800 that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure. The hook assembly may include a first bracket mounted on a first end of the example modular structure 800. A first end opposite of a hook end included in the hook assembly may be mounted onto the bracket. A second bracket may be mounted on a second end of the example modular structure 800 opposite the first end. The hook end may be mounted to the second bracket. The hook assembly may also include a turnbuckle. The turnbuckle is then tightened compressing each of the modular panels included between the first bracket and the second bracket together.
The ratchet straps 850a through 850h further compress each of the bays included in the example modular structure so that each of the panel joining assemblies and each of the panel joining assemblies included in the example modular structure 800 are further compressed together. The further compressing of the first structural joining assemblies and the second structural assemblies included in the example modular structure 800 serves to further strengthen the substantially moisture tight seal formed between each adjacent panel included in the example modular structure 800.
Each of the ratchet straps including ratchet straps 850a and 850b may be placed along a longitudinal axis of the example modular structure 800. Each of the ratchet straps may be placed on a top edge and a bottom edge along each of the modular panels that comprise each of the side walls of the example modular structure 800 and each of the divider panels included in the example modular structure 800. For example, ratchets straps 850a and 850b are placed on the top edge and the bottom edge of the side wall of the example modular structure 800. Additional ratchet straps (not shown) are also placed on the top edge and the bottom edge of a first set of divider panels (not shown) and a second set of divider panels (not shown) included inside the example modular structure 800. Additional ratchet straps (not shown) are also placed on the top edge and the bottom edge of the side wall of the example modular structure 800 opposite the side wall that ratchet straps 850 and 850 are placed. The plurality of ratchet straps may be placed in any location of the example modular structure 800 that further compresses the panel joining assemblies that will be apparent to those skilled in the relevant art(s) without departing from the scope of the present disclosure.
FIG. 9 is a flowchart of exemplary operational steps of an example modular structure according to an exemplary embodiment of the present disclosure. The present disclosure is not limited to this operational description. Rather, it will be apparent to persons skilled in the relevant art(s) from the teaching herein that other operational control flows are within the scope of the present disclosure. The following discussion describes the steps in FIG. 9.
At step 910, the operational control flow forms a center compartment by a first set of panels from a plurality of panels.
At step 920, the operational control flow forms a first side compartment coupled to the center compartment formed by a second set of panels from the plurality of panels.
At step 930, the operational control flow forms a second side compartment coupled to the center compartment opposite the first side compartment formed by a third set of panels from the plurality of panels.
At step 940, the operational control flow joins each panel from the plurality of panels to each respective adjacent panel via a panel joining assembly to substantially prevent moisture from entering the modular structure. For example as shown in FIG. 7A, the operational control flow joins the upper roof panel 710 with the first end panel 310 via the panel joining assembly 730. An example of the panel joining assembly 730 is shown in FIG. 2D. The joining of the upper roof panel 710 with the first end panel 310 via the panel joining assembly substantially prevents moisture from entering the modular structure.
At step 950, the operational control flow couples an upper roof panel to the center compartment so that the upper roof panel is a roof for the center compartment.
At step 960, the operational control flow couples a first lower roof panel to the first side compartment so that the first lower roof panel is a roof for the first side compartment.
At step 970, the operational control flow couples a second lower roof panel to the second side compartment so that the second lower roof panel is a roof for the second side compartment.
At step 980, the operational control flow joins the upper roof panel to each of the first and second lower roof panels via a roof joining assembly so that the upper roof panel is elevated relative to the first and second lower roof panels to substantially prevent moisture from entering the modular structure. Specifically, as shown in FIG. 7A, upper roof panel 710, for example, is joined to the first lower roof panel 610 via a roof joining assembly 720a so that upper roof panel 710 is elevated relative to the first lower roof panel 610 to substantially prevent moisture from entering the modular structure. An example of the roof joining assembly 720a is shown in FIG. 7B.
