[0044] The following is a detailed description with reference to specific embodiments. It should be noted that the serial numbers of the following embodiments are not intended to limit the preferred order of the embodiments.

[0045] See also Figures 1 to 4 , Figure 1 is a schematic diagram of the three-dimensional structure of the unit module provided in the embodiment of the present application, Figure 2 is a front view structural diagram of a unit module provided in an embodiment of the present application, Figure 3 is a schematic diagram of a top view of a unit module provided in an embodiment of the present application, Figure 4 It is along Figure 3 The right side cross-sectional structure diagram taken along the center line P-P'. Figures 1 to 4 As shown, the modular building structure includes a plurality of unit modules 10 that can be spliced ​​together. The unit module 10 includes a module bottom frame 11, a module top frame 12 and a detachable module column 13A, wherein the module bottom frame 11 and the module top frame 12 are arranged relative to each other, and the first end of the detachable module column 13A is detachably connected to the module bottom frame 11, and the second end of the detachable module column 13A is rotatably connected or detachably connected to the module top frame 12. The first end of the detachable module column 13A and the second end of the detachable module column 13A are opposite ends of the detachable module column 13A.

[0046] Furthermore, the detachable modular column 13A has a first state and a second state. Specifically, when the detachable modular column 13A is in the first state, the first end of the detachable modular column 13A is connected to the module base frame 11, and the second end of the detachable modular column 13A is connected to the module top frame 12. When the detachable modular column 13A is in the second state, the first end of the detachable modular column 13A is detached from the module base frame 11. In this way, the space within the building composed of multiple unit modules 10 can be adjusted by adjusting the connection method of the detachable modular columns 13A in the unit modules 10. This not only enables the large space of a modular building, but also enables the modular building to switch between large and small spaces to adapt to different building space requirements. It has a wide range of applications and is easy and quick to modify.

[0047] In some embodiments, the second end of the detachable module column 13A can be rotatably connected to the module top frame 12, and when the detachable module column 13A is in the second state, the first end of the detachable module column 13A can be detachably connected to the module bottom frame 11. In other embodiments, the second end of the detachable module column 13A can also be detachably connected to the module top frame 12, and when the detachable module column 13A is in the second state, the second end of the detachable module column 13A can be in a detached state from the module top frame 12.

[0048] In this way, in a building structure composed of a plurality of unit modules 10, when the detachable module column 13A of a certain unit module 10 is in the first state, that is, when the opposite ends of the detachable module column 13A of the unit module 10 are respectively connected to the module bottom frame 11 and the module top frame 12, an independent small space can be provided in the unit module 10. Furthermore, when a larger space is needed, when the second end of the detachable module column 13A is rotatably connected to the module top frame 12, the user can first remove the first end of the detachable module column 13A of the unit module 10 from the module bottom frame 11, and then can forcefully rotate the detachable module column 13A of the unit module 10 around its second end toward the module top frame 12 of the unit module 10 until the detachable module column 13A of the unit module 10 is in close contact with the module top frame 12 of the unit module 10, and then can detachably remove the first end of the detachable module column 13A of the unit module 10. The detachable modular column 13A of the unit module 10 is connected to the module top frame 12, thereby transforming the detachable modular column 13A of the unit module 10 from the first state to the second state. The detachable modular column 13A in the second state can reinforce the module top frame 12. Alternatively, when a larger space is required, when the second end of the detachable modular column 13A is detachably connected to the module top frame 12, the user can directly remove the opposite ends of the detachable modular column 13A of the unit module 10 from the module bottom frame 11 and the module top frame 12, thereby transforming the detachable modular column 13A of the unit module 10 from the first state to the second state. Moreover, when the detachable modular column 13A of the unit module 10 is in the second state, the small space within the unit module 10 can be spliced ​​with the spaces within other unit modules 10 to form a larger space. Therefore, by switching the detachable modular column 13A of the unit module 10 between the first state and the second state, not only can a large space be achieved by splicing multiple unit modules 10 into a modular building, but also a modular building can switch between large and small spaces.

[0049] In this embodiment, if Figures 1 to 4 As shown, the module bottom frame 11 may include four bottom module beams 111, which are sequentially connected end to end to form a bottom rectangular frame 11A. The module top frame 12 may include four top module beams 121, which are sequentially connected end to end to form a top rectangular frame 12A. The unit module 10 may include four module columns 13, one end of each of the four module columns 13 can be connected to the four corners of the bottom rectangular frame 11A, and the other end can be connected to the four corners of the top rectangular frame 12A, thereby achieving a complete module structure by connecting a bottom rectangular frame 11A, a top rectangular frame 12A, and four module columns 13.

[0050] Specifically, at least one of the four module columns 13 is a detachable module column 13A. For example, one, two, three, or four of the four module columns 13 may be detachable module columns 13A, that is, the unit module 10 may have one, two, three, or four detachable module columns 13A.

[0051] Specifically, in the above-mentioned unit module 10, the first end of each detachable module column 13A can be detachably connected to a corner of the bottom rectangular frame 11A, and the second end of each detachable module column 13A can be rotatably connected or detachably connected to a corner of the top rectangular frame 12A.

[0052] Specifically, in the above-mentioned unit module 10 , the bottom module beam 111 and the top module beam 121 are used to bear force and can be arranged horizontally, and the fixed module column 13B is used to bear force and can be arranged vertically.

[0053] Furthermore, in a specific implementation, in the above-mentioned unit module 10, when a certain detachable module column 13A is in a first state, the first end and the second end of the detachable module column 13A can be respectively connected to a corner of the bottom rectangular frame 11A and a corner of the top rectangular frame 12A, and when the detachable module column 13A is changed from the first state to the second state, the connection between the first end of the detachable module column 13A and a corner of the bottom rectangular frame 11A, and the connection between the second end of the detachable module column 13A and a corner of the top rectangular frame 12A can both be disconnected, or the connection between the second end of the detachable module column 13A and a corner of the top rectangular frame 12A can remain unchanged, and the first end of the detachable module column 13A can be changed from a state of being connected to a corner of the bottom rectangular frame 11A to a state of being connected to a top module beam 121 of the top rectangular frame 12A in a detachable manner.

[0054] Exemplarily, the top module beam 121 and the bottom module beam 111 may be a trough-section beam, an I-section beam or an I-section beam, and circular bolt holes may be provided on the top module beam 121 and the bottom module beam 111 so as to facilitate the connection between the top module beams 121 of adjacent unit modules 10 in the horizontal direction in the building as a whole composed of multiple unit modules 10, and the connection between the bottom module beams 111 of adjacent unit modules 10 in the horizontal direction, and the connection between the top module beams 121 and the bottom module beams 111 of upper and lower adjacent unit modules 10.

[0055] In some embodiments, as Figures 1 to 4As shown, in the above-mentioned bottom rectangular frame 11A, the four corners of the above-mentioned bottom rectangular frame 11A can be respectively provided with four bottom corner pieces 112, and the above-mentioned four bottom module beams 111 can be connected together through the four bottom corner pieces 112, and the first ends of the above-mentioned four module columns 13 can be respectively connected to the four corners of the bottom rectangular frame 11A through the four bottom corner pieces 112.

[0056] Specifically, in the above-mentioned bottom rectangular frame 11A, opposite ends of each bottom module beam 111 can be fixed to two bottom corner pieces 112 respectively, for example, they can be fixed to the two bottom corner pieces 112 respectively by welding.

[0057] Specifically, if Figures 1 to 4 As shown, the module base frame 11 may further include a rotatable connecting lug 113, which is used to connect the detachable module column 13A and the bottom corner piece 112. In other words, in the unit module 10, the first end of each detachable module column 13A can be connected to the corresponding bottom corner piece 112 via the rotatable connecting lug 113.

[0058] The rotatable connecting lug 113 can be provided on the top side of the bottom corner fitting 112. Specifically, the rotatable connecting lug 113 can be rotatably connected to the bottom side of the bottom corner fitting 112. Thus, when the first end of the detachable module column 13A is disconnected from the bottom corner fitting 112, that is, when the rotatable connecting lug 113 is not in use, the rotatable connecting lug 113 can be rotated, folded, and hidden within the surface layer, without affecting the use of the surface layer. For example, the rotatable connecting lug 113 can be connected to the bottom side of the bottom corner fitting 112 using a hinge.

[0059] Furthermore, in specific implementation, Figure 5 As shown, the first end of the detachable module column 13A can be provided with a bottom end connecting ear plate 131. Figure 4 and Figure 5 As shown, the bottom end connecting ear plate 131 of the above-mentioned detachable module column 13A can be detachably connected to the rotatable connecting ear plate 113 provided on the top side of the corresponding bottom corner piece 112 through the pin shaft 14, thereby realizing the detachable connection between the first end of the above-mentioned detachable module column 13A and the above-mentioned module bottom frame 11 (or the above-mentioned bottom rectangular frame 11A).

[0060] In some embodiments, as Figures 1 to 4As shown, in the above-mentioned top rectangular frame 12A, the four corners of the above-mentioned top rectangular frame 12A can be respectively provided with four top corner pieces 122, and the above-mentioned four top module beams 121 can be connected together through the four top corner pieces 122, and the second ends of the above-mentioned four module columns 13 can be respectively connected to the four corners of the top rectangular frame 12A through the four top corner pieces 122.

[0061] Specifically, in the above-mentioned top rectangular frame 12A, the opposite ends of each top module beam 121 can be fixed to the two top corner pieces 122 respectively, for example, they can be fixed to the two top corner pieces 122 respectively by welding.

[0062] Specifically, if Figures 1 to 4 As shown, the module top frame 12 may further include a fixed connection ear plate 123, which is used to connect the detachable module column 13A and the top corner piece 122. In other words, in the unit module 10, the second end of each detachable module column 13A can be connected to the corresponding top corner piece 122 via the fixed connection ear plate 123.

[0063] The fixed connection ear plate 123 can be provided on the bottom side of the top corner piece 122. Specifically, the fixed connection ear plate 123 can be fixedly connected to the bottom side of the top corner piece 122, for example, can be fixedly connected to the bottom side of the top corner piece 122 by welding.

[0064] Furthermore, in specific implementation, Figure 5 As shown, the second end of the detachable module column 13A can be provided with a top connection ear plate 132. Figure 4 and Figure 5 As shown, the top connecting ear plate 132 of the above-mentioned detachable module column 13A can be detachably connected or rotatably connected to the fixed connecting ear plate 123 provided on the bottom side of the corresponding top corner piece 122 through a pin shaft 15, thereby realizing a detachable connection or rotatable connection between the second end of the above-mentioned detachable module column 13A and the above-mentioned module top frame 12 (or the above-mentioned top rectangular frame 12A).

[0065] In some specific embodiments, Figures 1 to 5As shown, the top connection ear plate 132 of the above-mentioned detachable modular column 13A can be rotatably connected to the fixed connection ear plate 123 provided on the bottom side of the corresponding top corner piece 122 through the pin shaft 15, and the bottom connection ear plate 131 of the above-mentioned detachable modular column 13A can be detachably connected to the rotatable connection ear plate 113 provided on the top side of the corresponding bottom corner piece 112 through the pin shaft 14. Moreover, when the above-mentioned detachable modular column 13A is in the first state, the top connection ear plate 132 of the above-mentioned detachable modular column 13A can be connected to the fixed connection ear plate 123 provided on the bottom side of the corresponding top corner piece 122 through the pin shaft 15, and the bottom connection ear plate 131 of the above-mentioned detachable modular column 13A can be connected to the rotatable connection ear plate 113 provided on the top side of the corresponding bottom corner piece 112 through the pin shaft 14. When it is necessary to change the above-mentioned detachable modular column 13A from the first state to the second state, the user can first remove the pin shaft 14 to disconnect the bottom connection ear plate 113 of the above-mentioned detachable modular column 13A. The end connecting ear plate 131 is connected to the rotatable connecting ear plate 113 on the top side of the corresponding bottom corner piece 112, and then the above-mentioned detachable module column 13A can be rotated around the pin shaft 15 by a certain angle (for example, 90 degrees) to make the above-mentioned detachable module column 13A close to a top module beam 121 of the above-mentioned unit module 10, and then the first end of the above-mentioned detachable module column 13A can be connected to a top module beam 121 of the above-mentioned unit module 10 in a detachable manner, thereby realizing the transformation of the detachable module column 13A of the unit module 10 from the first state to the second state.

[0066] It should be noted that in this embodiment, by using a rotatable connecting lug 113 and a fixed connecting lug 123 to connect the removable module column 13A to the bottom corner fitting 112 and the top corner fitting 122 via pins 14 / 15, the removable module column 13A can be disassembled on site without cutting, which helps improve on-site work efficiency. Furthermore, after disconnecting the removable module column 13A from the bottom corner fitting 112, the removable module column 13A can be rotated along the top pin 15 and the removable module column 13A can be integrally connected to the module top frame 12 (or the top rectangular frame 12A or the top module beam 121), thereby reinforcing the module top frame 12 (or the top rectangular frame 12A or the top module beam 121). Furthermore, during the entire disassembly and assembly process, no welding is required on site, and no unnecessary materials are added, making the connection convenient.

[0067] For example, Figure 5As shown, the first end of the detachable modular column 13A may further be provided with a first end plate (not shown), and the second end of the detachable modular column 13A may further be provided with a second end plate 133 to enhance the structural strength of the detachable modular column 13A. Furthermore, in a specific implementation, the first end plate and the bottom connecting ear plate 131 may be welded to the first end of the detachable modular column 13A, and the second end plate 133 and the top connecting ear plate 132 may be welded to the second end of the detachable modular column 13A.

[0068] In some embodiments, as Figures 1 to 4 As shown, at least one of the four module columns 13 can be a fixed module column 13B, and the other module columns 13 except the fixed module column 13B can all be the detachable module columns 13A. In other words, the four module columns 13 can be composed of at least one fixed module column 13B and at least one detachable module column 13A. For example, Figures 1 to 4 As shown, three of the four module columns 13 may be fixed module columns 13B, and one module column 13 may be a detachable module column 13A, that is, the four module columns 13 may be composed of three fixed module columns 13B and one detachable module column 13A.

[0069] Furthermore, in the above-described unit module 10, opposite ends of each fixed module column 13B may be fixedly connected to the bottom rectangular frame 11A and the top rectangular frame 12A, respectively. Specifically, one end (e.g., the bottom end) of each fixed module column 13B may be fixedly connected to a bottom corner piece 112 of the bottom rectangular frame 11A, and the other end may be fixedly connected to a top corner piece 122 of the top rectangular frame 12A.

[0070] In some embodiments, as Figure 6 As shown, the bottom side of the bottom corner piece 112 may be provided with a bottom connecting plate 1121, and the bottom connecting plate 1121 is configured to connect the unit module 10 with other unit modules located below the unit module 10. Specifically, the bottom connecting plate 1121 may be provided with bolt holes 1121A, and the unit module 10 can be connected to other unit modules located below it through the bolt holes 1121A. In this way, the connection between the unit modules 10 can be achieved, facilitating assembly.

[0071] For example, Figure 6As shown, the bottom corner fitting 112 can be a hexahedral corner fitting and can be welded from common steel structural materials, or it can be an integrally cast steel part. Specifically, the bottom connecting plate 1121 can be provided protruding laterally from the bottom of the bottom corner fitting 112. Each side of the bottom corner fitting 112 can have holes for hoisting the unit module 10 or for providing passage for electromechanical pipelines.

[0072] In some embodiments, as Figure 7 As shown, a top connecting plate 1221 may be provided on the top side of the top corner piece 122. This connecting plate 1221 is configured to connect the unit module 10 with other unit modules located on top of the unit module 10. Specifically, bolt holes 1221A may be provided on the top connecting plate 1221, and the unit module 10 may be connected to other unit modules located on top of it via the bolt holes 1221A. This allows for connection between the unit modules 10, facilitating assembly.

[0073] For example, Figure 7 As shown, the top corner fitting 122 can be a hexahedral corner fitting and can be welded from common steel structural materials, or it can be an integrally cast steel part. Specifically, the top connecting plate 1221 can be provided protruding laterally from the top of the top corner fitting 122. Each side of the top corner fitting 122 can have holes for hoisting the unit module 10 or for providing passage for electromechanical pipelines.

[0074] In the above embodiment, if Figures 8 to 15 As shown, the number of unit modules 10 included in the above-mentioned modular building structure can be multiple, and the multiple unit modules 10 are spliced ​​into a building as a whole, and the building as a whole is at least one layer structure. Among them, each layer structure 1 (for example, the first layer structure 1-1 or the second layer structure 1-2) can include at least one unit module group 1A, and each unit module group 1A is composed of at least two unit modules 10 (for example, the first unit module 10-1, the second unit module 10-2, the third unit module 10-3 and the fourth unit module 10-4) that converge on the same common splicing line L1 and splice together, and for each unit module group 1A, each unit module 10 in the unit module group 1A has a detachable module column 13A corresponding to the common splicing line L1. Moreover, all the detachable module columns 13A at the common splicing line L1 are in the first state, and all the detachable module columns 13A at the common splicing line L1 are arranged against each other (as shown in FIG. Figures 8 to 11 shown).

[0075] In this way, the unit module group 1A can be switched between the small space and large space states by switching all the detachable module columns 13A at the same common splicing line L1 of the unit module group 1A between the first state and the second state. When all the detachable module columns 13A at the same common splicing line L1 of the unit module group 1A are in the first state, the unit module group 1A can provide a small space (such as Figures 8 to 11 As shown), the unit module group 1A can provide a large space (as shown) when all the detachable module columns 13A located at the same common splicing line L1 are in the second state. Figures 12 to 15 As shown), it can not only realize the construction of large space to improve the utilization rate of building space, but also can reverse the operation to change the large space into a small space, and the transformation is fast and convenient.

[0076] In some embodiments, as Figures 8 to 15 As shown, the building formed by the above-mentioned multiple unit modules 10 can be a multi-layer structure, and two adjacent layers (for example, the first layer structure 1-1 and the second layer structure 1-2) can be connected by a connecting plate 20 and a connecting bolt 30 to increase the overall strength of the building formed by the above-mentioned multiple unit modules 10.

[0077] Specifically, in the above embodiment in which the second end of the detachable module column 13A in the unit module 10 is rotatably connected to the module top frame 12, as shown in FIG. Figure 12 As shown, all the detachable module columns 13A at the common splicing line L1 are in the second state, the second ends of all the detachable module columns 13A at the common splicing line L1 are adjacent to the common splicing line L1, and the first end of each detachable module column 13A at the common splicing line L1 can be detachably connected to the module top frame 12 (or the top rectangular frame 12A or the top module beam 121) of the unit module 10 to which it belongs, so that the detachable module columns 13A in the second state reinforce the module top frame 12 (or the top rectangular frame 12A or the top module beam 121) to improve the safety and stability of the overall building spliced ​​by the above-mentioned multiple unit modules 10 in a large space state.

[0078] In some embodiments, as Figure 13 and Figure 16As shown, the top module beam 121 may be provided with a top module beam connecting lug 124, and the top module beam connecting lug 124 may be configured to be detachably connected to the first end of the detachable module column 13A via a pin 16 when the detachable module column 13A is in the second state. Specifically, in the building structure formed by the plurality of unit modules 10, all the detachable module columns 13A at the common splicing line L1 are in the second state, and the first end (e.g., the bottom end connecting lug 131) of each detachable module column 13A at the common splicing line L1 may be correspondingly connected to the top module beam connecting lug 124 provided on the top rectangular frame 12A of the unit module 10 to which it belongs via a pin 16, thereby achieving a detachable connection between the first end of each detachable module column 13A at the common splicing line L1 and the module top frame 12 (or the top rectangular frame 12A or the top module beam 121) of the unit module 10 to which it belongs.

[0079] In some embodiments, as Figure 14 、 Figure 15 and Figure 17 As shown, the modular building structure may further include a connecting cover plate 40, which is configured to connect the second ends (e.g., the top connecting ear plate 132) of all the detachable module columns 13A at the common splicing line L1 when all the detachable module columns 13A at the common splicing line L1 are in the second state. Specifically, in the building structure formed by the above-mentioned multiple unit modules 10, when all the detachable module columns 13A at the common splicing line L1 are in the second state, the connecting cover plate 40 may be connected below the second ends of all the detachable module columns 13A at the common splicing line L1. In this way, the overall strength of the building structure formed by the above-mentioned multiple unit modules 10 in a large space state can be improved to ensure the safety and stability of the overall structure.

[0080] As can be seen from the above, the modular building structure provided by this embodiment includes a plurality of unit modules that can be spliced ​​together, and the unit module includes a module bottom frame, a module top frame and a detachable module column, wherein the module bottom frame and the module top frame are arranged relative to each other, and the first end of the detachable module column is detachably connected to the module bottom frame, and the second end of the detachable module column is rotatably connected or detachably connected to the module top frame, the first end of the detachable module column and the second end of the detachable module column are opposite ends of the detachable module column, and the detachable module column has a first state and a second state, and when the detachable module column is in the first state, the first end of the detachable module column is detachably connected to the module bottom frame. The module bottom frame is in a connected state, the second end of the detachable module column is in a connected state with the module top frame, and when the detachable module column is in the second state, the first end of the detachable module column and the module bottom frame are in a detached state. Therefore, after a plurality of unit modules are spliced ​​into a building as a whole, the space in the building as a whole formed by splicing a plurality of unit modules can be adjusted by adjusting the connection method of the detachable module column. Therefore, not only a large space of a modular building can be realized, but also the modular building can be switched between large space and small space to adapt to different building space requirements. It has a wide range of applications and is convenient and quick to transform.
