In a specific embodiment of the present invention as shown in the first to third figures, a modular structure 101 is provided, which has a first module 105 and is rotatably coupled to the first module through a joint assembly. A second module 106 of 105. In this specific embodiment, the engagement is always a rotation mechanism 115 configured to allow the first module to rotate about a main axis. The first module 105 is smaller than the second module 106 and is nested within the second module 106 when the modular structure 101 is in an unexpanded position.

As shown in the second and third figures, the first module 105 and the second module 106 each include a plurality of pillars and interconnected beams to form a self-supporting structure. In particular, the second figure shows the structure of the first module 105 according to a specific embodiment of the present invention. In this specific embodiment, the first plurality of bottom rails 105B are interconnected to form the base of the first module 105, and the first plurality of top rails 105A are interconnected to form the top of the first module 105. The top end of the first module 105 is connected to the base through a first plurality of pillars 105C, and at the same time, cross pillars 105F and a top support frame 105E are provided to strengthen the structural integrity of the first module 105.

Similarly, the base and the top end are connected through a plurality of posts 106E. At the same time, the cross pillars 106H and the top support frame 106G are provided to strengthen the structural integrity of the second module 106.

As described above, the first module 105 and the second module 106 are rotationally coupled through the rotation mechanism 115. As shown in the third embodiment, the rotating mechanism 115 includes a ball bearing located in the structural frame 106F of the second module 106. The ball bearing may be a ball transmission unit, a transmission bearing, or any other mechanism that allows the first module 105 to rotate smoothly with respect to the second module 106. As shown in the second figure, at least one steel base plate 105D is further provided on the first module 105, which is configured to be connected once the first and second modules are connected together (as shown in the first figure). Positioned directly on top of the ball bearing. In the specific embodiment shown in the second figure, a steel base plate 105D is positioned above each ball bearing. In the illustrated embodiment, the rotation mechanism 115 has a rotation center 110 after assembly.

Please refer to FIG. 4A at this moment. The second module 106 may further include at least one detachable wall 107. As will be further explained later, the separable wall 107 is configured to surround the first module 105 when the modular structure 101 is in the unexpanded position, and can be used as an opening to allow the first module 105 to rotate outward, and when the module When the grouping structure 101 is changed to the expanded position, the second module 106 can expand outward.

The fourth diagrams A to D illustrate the operation of the modular structure 101 in further detail. As shown in FIG. 4A, when the modular structure 101 is in the unexpanded position, the first module 105 is nested in the second module 106. In this position, the separable wall 107 has been closed, and the first module 105 is enclosed in the second module 106. Once the modular structure 101 arrives at the site and is positioned, the detachable wall 107 of the second module 106 can be opened to expose the first module 105. The first module 105 then rotates around the rotation center 110 of the rotation mechanism 115. Once the first module 105 reaches the expanded position, the detachable wall 107 will be closed again, thereby fixing the first module 105 in position (as shown in the fourth D figure).

Therefore, this configuration shortens the time required to construct a multi-room apartment. In particular, the modular structure 101 of the present invention allows the living space of two units to be transported and transported to the site as a single module, wherein the first module is packaged in the second module during transportation. This significantly reduces shipping and transportation costs. Furthermore, using the rotating mechanism of this specific embodiment, the modular structure 101 can quickly build the modules with minimal manpower after arriving at the scene.

Therefore, due to its ease of deployment, the modular structure 101 of the present invention has a variety of applications, such as temporary structures for military or commercial purposes, or even suitable for building long-term residences in remote construction sites without economic benefits house.

Furthermore, the present invention allows the modular structure 101 to be fixed when it is in an unexpanded position. In particular, when the modularized structure 101 is in the unexpanded position as shown in the fourth A diagram, the separable wall 107 will swell, and the first module 105 is nested inside the second module 106. This further increases the convenience of transportation when the modular structure 101 is in the unexpanded position.

In addition, rotary bearings such as ball bearings can withstand the static and dynamic forces applied by the rotary module. Therefore, the use of a ball bearing as a part of the rotating mechanism provides smooth rotation and extends the life of the rotating mechanism.

Although the modular structures 101 in FIGS. 4A to 4D are illustrated as having only two sets of separable walls 107, it should be understood that these separable walls can have many configurations, such as the fifth A to fifth The configuration shown in Figure F, in which there are more than two sets of separable walls on the second module 156. In this regard, the fifth E diagram shows a top view of the completed and assembled modular structure 151, where the first and second modules 155, 156 are fully expanded.

Therefore, this configuration allows the modular structure to be modified according to design requirements. For example, if larger modules are needed, the size of the first and second modules can be enlarged, and more separable walls can be added in order to Meet geometric requirements that are not included in the structural integrity of the modular structure.

Please refer back to the second and third figures. In a further specific embodiment of the present invention, the second module 106 may further include a plurality of pairs of corner castings disposed on the ends of each pillar 106E. Each diagonal casting includes a lower corner casting 106D and an upper corner casting 106C. In this embodiment, the post 106E is hollow so as to provide a passage therethrough.

A specific example of the upper corner casting 106C is shown in the sixth A and sixth B drawings. In this specific embodiment, the upper corner casting 106C includes a first top plate, a first bottom plate, and four first side plates joined or cast together to form the upper corner casting 106C. A first top opening 118, a first bottom opening 119, and four first side openings 120 are provided on the first top plate, the first bottom plate, and the four first side plates, respectively. As shown in the sixth A diagram, the first top opening 118 is configured to be larger than the first bottom opening 119.

Figures 6C and 6D further show a specific embodiment of the lower corner casting 106D in further detail. Similar to the upper corner casting 106C, the lower corner casting 106D includes a second top plate, a second bottom plate, and four second side plates joined or cast together to form the lower corner casting 106D. A second top opening 122, a second bottom opening 123, and four second side openings 124 are provided on the second top plate, the second bottom plate, and the four second side plates, respectively. As shown in FIG. 6C, the second top opening 122 is configured to be smaller than the second bottom opening 123.

Therefore, this configuration allows two or more modular structures to be stacked or placed next to each other, thereby forming an apartment as shown in FIGS. 7A to 7J. In particular, for a module with a fixed vertical connection, at least one binding member can be inserted into the corner castings 106C, 106D and the hollow column 106E of an adjacent module.

One such binding member that can be used according to this embodiment is the link as shown in Figures 8A to 8C. In this embodiment, the connecting rod 130 includes an internally threaded sleeve head 132 and an externally threaded tail portion 135, and the threads of the externally threaded tail portion 135 and the internally threaded sleeve head 132 are complementary. The sleeve head 132 is configured to have a larger outer diameter than the rotating shaft 140, the first top opening 118 of the upper corner casting 106C, and the second bottom opening 123 of the lower corner casting 106D. Further, the sleeve head 132 is also configured to have an outer diameter smaller than that of the first bottom opening 119 of the upper corner casting 106C.

In operation, the first connecting rod 130 will be inserted into the corner castings and the hollow column of the second module of the first modular structure. The sleeve head will pass through the first top opening 118 of the upper corner casting and be adjacent to the first bottom plate of the upper corner casting, thus fixing the first modular structure. A second modular structure is then stacked on top of the first modular structure, and a second link 130 is inserted into the corner castings and the hollow of the second module of the second modular structure. Inside the column. As with the first link, the sleeve head of the second link will also be adjacent to the first base plate of the upper corner casting of the second modular structure. At the same time, the externally threaded tail portion of the second connecting rod 130 will pass through the first bottom opening 119 of the upper corner casting and the second top opening 122 of the lower corner casting, so as to interact with the internal thread sleeve of the first connecting rod The barrel head is engaged, thereby fixing the second modular structure to the first modular structure.

For horizontal bonding modules, horizontal binding members can also be used to fix the modules in position. An example of the horizontal binding member that can be used according to this specific embodiment is the interlocking plate as shown in FIG. 8D. In this embodiment, the interlocking plate 212 is placed on the upper corner casting of the adjacent second module, so that each plate hole 214 is aligned with the opening of the upper corner casting 106C of the second module. The plate hole 214 is configured to allow a vertical binding member to pass through, such as the binding member shown in Figures 8A to 8C, thus fixing the interlocking plate 212 and the modular structure in position.

Other binding members can also be used to fix adjacent modular structures together. This will include, but is not limited to, at least one tension cable and at least one pair of anchors.

For alternative configurations, the binding member may include a series of fixed anchor blocks and post-stress cables located on the peripheral edges of the modules, where the fixed anchor blocks are located on the connecting portions of the modules. For example, the corner castings may include end anchors that are configured to resist a post-stress cable connecting adjacent modules and bind the modules into the building structure. This configuration is shown in the ninth figure, so that the link can be used as a binding member, as shown in Figures 8A to 8C. For this alternative embodiment, the end connection 322 is modified to receive a fixed anchor 321, which is used to resist the post-stress of the cable 320. In this way, when the various modules are already positioned and aligned, the cable is tightened to connect the positioned modules to form an integrated building structure.

Therefore, this configuration allows for the rapid and efficient construction of multi-room or multi-story apartment buildings, thereby increasing building productivity and thus reducing building costs.

Although the second module of the present invention is illustrated as including angle castings, it should be understood that the operation of the present invention does not require such angle castings. In particular, as described earlier, one of the main functions of the corner castings is to help secure the modules using the binding members in Figures 8A to 8C. Therefore, those skilled in the art will understand that any mechanism that allows any binding member to fix the modules can be used for the purpose of the present invention.

It should be understood that the first module 105 can also be rotated relative to the second module 106 without departing from the field of the present invention, so as to meet the design requirements of the building.

It should also be understood that the modular structure 101 can be completed in advance in the factory, and its internal equipment is fully installed and completed for transportation to the construction site.

Therefore, this facilitates efficient construction on site and determines that all gaps are considered and water sealed before the completed modular structure is transported to the construction site. As a result, it is possible to minimize defects occurring on site construction.

In a further specific embodiment of the present invention as shown in FIGS. 10A and 10B, instead of the ball bearings described earlier, the rotation mechanism 1115 may be a ball located on the top of the base structure frame 1106F of the second module 1106. Bearing rotating plate 1106J. A transfer bearing (not shown) may be positioned between the ball bearing rotating plate 1106J and the base structure frame 1106F for rotation. The ball bearing rotating plate 1106J is configured to be joined to the substrate 1105G on the first module 1105 through the hole 1105H, wherein the substrate 1105G is positioned adjacent to the bottom rail 1105B (as shown in the tenth B figure). In the illustrated embodiment, a pivot 1106K is also positioned on the top support 1106G and aligned with the rotation center 1110. The pivot 1106K is configured to be engaged with the top plate 1105J on the top support frame 1105E of the first module 1105 (as shown in the tenth figure B).

As a result, once the first and second modules 1105, 1106 have been assembled, the first module 1105 can rotate around the rotation center 1110, from an unexpanded position to an expanded position, and vice versa.

In a further specific embodiment of the present invention, the first and second modules may further include wall panels and roof panels connected to the sides, tops or bases of the first and / or second modules, respectively. Or at least one of the floor. These panels can be assembled in the factory before being shipped to the construction site for assembly. As a result, the time required for construction is further reduced.

Still in another specific embodiment of the present invention as shown in FIGS. 11 to 14B, the first and third modules 2105, 2107 are provided (as shown in FIGS. 14A and 14B, respectively).

In particular, the rotation mechanisms 2105A, 2107A may include a ball bearing, a ball transmission unit, or a ball bearing rotating plate as described earlier. However, it should be understood that the rotating mechanisms 2105A, 2107A may also be any mechanism that allows the first and third modules 2105, 2107 to rotate smoothly with respect to the second module 2106.

Therefore, a larger modular structure 2101 can be completed in advance in the factory, and its internal equipment is fully installed and completed for transportation to the construction site. This helps to easily build large modules in the field.

It should be understood that more than two modules are rotatably coupled to the second module and are configured to be nested within the second module when the modular structure is in the unexpanded position. In this case, the number of rotation mechanisms is equal to the number of modules rotationally connected to the second module.

In a specific embodiment of the present invention, the modular structures of the present invention can be stacked up to a height of 10 floors. It should be understood, however, that according to building codes and regulations, the modular structure can be stacked over a height of 10 floors.

In a specific embodiment of the present invention, when the modular structure is in an unexpanded position, its size is equal to the size of a standard container. For example, the modular structure may have the same size as a standard 20-foot or 40-foot container. In other specific embodiments, the modular structure of the present invention may have a size corresponding to the requirements of the construction site.

Therefore, this configuration facilitates transportation to the construction site. In particular, the modular structure can be transported by ordinary transportation methods, such as cranes and pushers using twist locks to engage, lift, and disengage the modular structure. Furthermore, if transportation is required from a distance, transportation companies and / or international ports can use standard equipment and trailers to lift, move, load and transport these modules. All of this will reduce transportation costs and thus overall construction costs.

Still in another specific embodiment of the present invention as shown in FIGS. 15 to 20, the modular structure 3101 further includes an external module 3108, which is movably coupled to the second module 3106.

Furthermore, the first and / or second module 3105, 3106 is configured to be nested within the external module 3108 when the modular structure is in an unexpanded position, and when the modular structure is expanded When in position, it can expand beyond this second module. In order to reach the expanded position from the unexpanded position, both the second module 3106 or the external module 3108 are configured to perform a conversion with respect to each other.

A method of setting the modular structure 3101 will now be described. In a specific embodiment, the external module 3108 of the modular structure 3101 is first lifted from an unexpanded position as shown in FIG. 15 to an expanded position as shown in FIG. 16. This can be done by crane, stacker or any other standard lifting equipment. Then, the detachable wall 3106A of the second module 3106 will be opened (as shown in FIG. 17), thereby exposing the first module 3105 nested inside the second module 3106. As shown in Figures 18 and 19, the first module 3105 is then unscrewed out of the second module 3106, thus reaching the expanded position. Once the first module 3105 is in this expanded position, the detachable wall 3106A will be slung on, thereby fixing the modular structure 3101 in position (as shown in the twentieth figure).

Therefore, a modular structure will have multiple internal living spaces available. This allows large multi-story buildings to be hauled and pre-completed in the factory before being transported to the construction site for assembly.

Although when the modular structure is in the unexpanded position, the illustrated specific embodiment only shows that one module is nested in the second module. It should be understood that two or more modules may be nested in the first module. Inside two modules.

Although the present invention has been described with reference to specific embodiments, modifications and changes may be made in the design and / or details without departing from the spirit and scope of the invention.

For example, for the building structure with the scope of application for item 11, the second module is configured to expand beyond the first module when the modular structure is in the expanded position. For example, the building structure according to any one of claims 11 to 13, wherein the joint assembly further includes a rotation mechanism configured to allow the first module or the second module to rotate about at least one major axis. . For example, the building structure according to any one of claims 11 to 13, wherein the binding member includes at least one connecting rod configured to penetrate at least one edge of the second module, and the connecting rod includes an internally threaded end And an externally threaded end, the externally threaded end of the at least one connecting rod is configured to be fixed to a base of an adjacent second module. For example, the building structure according to any one of claims 11 to 13, wherein the binding member includes a combination of at least one force cable and at least one pair of end fixing anchors. For example, the building structure in any one of the 11th to 16th patent scopes further includes a third module movably connected to the second module, and the third module is configured as the modular structure When in the unexpanded position, it is nested within the second module and rotated from the unexpanded position to the expanded position relative to each other. For example, the building structure according to any one of claims 11 to 17, further includes an external module that is movably connected to the second module, and the second module is configured such that when the modular structure is in the When in the unexpanded position, it is nested inside the external module. For example, the building structure of claim 18, wherein the external module is configured to be displaceable relative to the second module.
