Description

Technical Field

[0002] Traditional high-rise building construction projects are characterized by long construction durations. To address this, modular technology uses prefabricated components for rapid assembly. With the increasing degree of integration, the most common modular units are now box-type building units. These units need to be transported from the prefabrication factory to the site for assembly, so their size is restricted by transportation dimensions: the weight of a typical module should not exceed 80 tons, the width should not exceed 3.4 meters, and the total height, including the truck, should not exceed 4.5 meters. Furthermore, in current prefabricated building practices, cast-in-place concrete or on-site welding techniques are still considered indispensable auxiliary means to ensure structural safety, strengthen node connections, enhance seismic performance, meet specific functional requirements, and adapt to complex structural layouts. However, the application of these technologies cannot overcome the size limitations of prefabricated component transportation, resulting in low prefabricated component transportation efficiency.

The transport fixing device 5 can be a rope, a steel wire, etc.

[0044] like Figure 5 and Figure 6 As shown, in the embodiment of the present application, the mounting seat 18 includes a base 181, two secondary ear plates 182 and a pin 183. One side of the base 181 is fixed to the side wall of the box column 13, and two secondary ear plates 182 are provided on the other side of the base 181. The two secondary ear plates 182 are arranged opposite to each other, and the two ends of the pin 183 are respectively rotated on the two secondary ear plates 182. The outward-turned frame 2 includes a ring beam 21 and a main ear plate 22. The ring beam 21 includes a first rod 211 and a plurality of second rods 212 arranged on one side of the first rod 211. One end of the second rod 212 is provided with a main ear plate 22. The number of mounting seats 18 is the same as the number of main ear plates 22, and the main ear plates 22 are rotatably connected to the pin 183.

[0045] like Figure 7 As shown, in the embodiment of the present application, the first connecting part 17 includes a first fixing column 172, a first nut 173, a first hinge 174, a first fixing block 175 and two first fixing rings 171. The two first fixing rings 171 are fixed to one side of the box column 13. The two first fixing rings 171 are arranged at intervals. The first fixing block 175 is arranged on one side of the first hinge 174. The first fixing block 175 is located between the two first fixing rings 171. The side wall of the first fixing column 172 is provided with a thread. One end of the first fixing column 172 passes through the first fixing block 175 and the two first fixing rings 171 and is threadedly connected to the first nut 173. The first hinge 174 rotates around the first fixing column 172. A threaded hole is provided on the first hinge 174, and a threaded hole is provided on the second connecting part 23. When the deformable modular box unit is in a retracted state, the threaded hole on the first hinge 174 is aligned with the threaded hole on the second connecting part 23 and is connected by bolts.

[0046] like Figure 8 and Figure 9As shown, in the embodiment of the present application, the second connecting portion 23 includes a second fixing column 232, a second nut 233, a second hinge 234, a second fixing block 235 and two second fixing rings 231. The two second fixing rings 231 are fixed to one side of the box column 13. The two second fixing rings 231 are arranged at intervals. The second fixing block 235 is arranged on one side of the second hinge 234. The second fixing block 235 is located between the two second fixing rings 231. The side wall of the second fixing column 232 is provided with a thread. One end of the second fixing column 232 passes through the second fixing block 235 and the two second fixing rings 231 and is threadedly connected to the second nut 233. The second hinge 234 rotates around the second fixing column 232. A threaded hole is provided on the second hinge 234. When the deformable modular box unit is in a retracted state, the threaded hole on the first hinge 174 and the threaded hole on the second hinge 234 are aligned and connected by bolts.

[0047] In the embodiment of the present application, the deformable modular box unit also includes a diagonal rod 3, which includes a diagonal circular tube 31 and an embedded mounting plate 32 arranged at both ends of the diagonal circular tube 31. The embedded mounting plate 32 is provided with a threaded hole. When the deformable modular box unit is in the expanded state, the threaded holes on the embedded mounting plate 32 are respectively aligned with the threaded holes on the first hinge page 174 and the threaded holes on the second hinge page 234 and are connected by bolts.

[0048] The ends of the diagonal brace 3 connect the frame body 1 and the outward-turned frame body 2. The main tensile member is a diagonal circular tube 31, with embedded mounting plates 32 at the front and rear ends. These plates are inserted into the diagonal circular tube 31 and welded together to achieve a rigid connection to the brace. Bolts are used to connect the mounting plates to the connection points on the frame body 1 and the outward-turned frame body 2 through the reserved bolt holes in the mounting plates at the front and rear ends, forming a cantilever structure.

[0049] like Figure 10 As shown, the top end of the box column 13 is connected to the top flange 16 by bolts.

[0050] In the embodiment of the present application, the deformable modular box unit 10 is a steel structure.

[0051] In the transport state, the deformable modular box unit is in a retracted state, and the diagonal brace 3 is not installed. The connection parts provided on the frame box 1 and the outward-turning frame 2 are folded to be parallel to the installation surfaces on the box column 13 and the ring beam 21 respectively. The outward-turning frame 2 is retracted inward and parallel to the box column 13. At this time, the inner side of the ring beam 21 is flipped and contacts the mounting seat 18 on the frame box 1 to prevent excessive inward turning; the outer side of the ring beam 21 is flipped and fixed to the double-span H-shaped steel beam on the top of the frame box 1 through the transport fixing device 5 to prevent the module from turning outward. This reduces the collision between modules and components during transportation. Through this structure and transportation method, the size required for transportation can be greatly reduced.

[0052] During on-site installation, the deformable modular box unit 10 is in the expanded state, the outward-turned frame 2 is turned outward, and the connecting parts provided on the frame box 1 and the outward-turned frame 2 are folded to be perpendicular to the installation surfaces on the box column 13 and the ring beam 21 respectively. The diagonal rod 3 is fixed to the connecting parts on the frame box 1 and the outward-turned frame 2 by bolts. When connecting between modules, another module is hoisted above the existing module so that the four upper top flanges 16 of the deformable modular box unit 10 below are aligned with the four bottom flanges 110 of the deformable modular box unit 10 above. Bolts are used to fix the upper and lower modules through the bolt holes reserved on the flanges. This enables rapid installation without welding at the construction site.

[0053] See Figure 11-12 The present application provides a modular device, which includes at least two deformable modular box units 10. The deformable modular box units 10 are any of the deformable modular box units 10 described above. Among the two adjacent deformable modular box units 10, the bottom of the frame box 1 of one deformable modular box unit 10 is connected to the top of the frame box 1 of the other deformable modular box unit 10. The bottom flange 110 of the bottom of the frame box 1 of one deformable modular box unit 10 is connected to the top flange 16 of the top of the frame box 1 of the other deformable modular box unit 10 by bolts.

[0054] The present application discloses a deformable modular box unit and a modular device. The deformable modular box unit includes: a frame box body, one side of which is provided with a first connection portion, a mounting seat, and a beam bracket, the first connection portion being located above the mounting seat, and the beam bracket being located below the mounting seat; an outward-turning frame body, one side edge of the outward-turning frame body being rotatably connected to the mounting seat, and the other side edge of the outward-turning frame body being provided with a second connection portion; the deformable modular box unit includes an expanded state and a contracted state. When the deformable modular box unit is in the contracted state, one side of the outward-turning frame body is close to the frame box body, and the first connection portion and the second connection portion are in contact and connected. When the outward-turning frame body is rotated away from the frame box body by an external force, the second connection portion moves away from the first connection portion. When the other side of the outward-turning frame body abuts the beam bracket, the beam bracket restricts the rotation of the outward-turning frame body, and the deformable modular box unit enters the expanded state. The present application can improve the transportation efficiency of prefabricated parts.

[0055] This application can significantly reduce the transportation size of prefabricated buildings. Since welding, pouring and other installation methods are not used, pollution on the construction site can be greatly reduced. In addition, it can be installed and disassembled quickly without damage, achieving a high reuse rate. Due to the use of a factory-prefabricated and on-site assembled building model, the amount of traditional pouring work can be reduced, the progress of project site construction can be accelerated, and the quality of steel components can be guaranteed. Due to the use of a purely mechanical connection method, the integrity of the materials during construction and dismantling can be guaranteed, ensuring that they can be reused after subsequent dismantling, reducing the waste of building materials and improving sustainability. Due to the use of an outward-folding cantilever module, the size of the box module can be increased while the transportation size remains the same, avoiding the shortcomings of the narrow and monotonous traditional box modules.

[0056] The above is a detailed introduction to a deformable modular box unit and modular device provided by the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for those skilled in the art, based on the ideas of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
