[0002] In the current field of modular construction, the node connection technology between modules is the key to ensuring structural safety. Traditional modular building node connection methods are diverse, such as bolt connection, welding connection, prestressed connection and self-locking connection.

[0003] Each of these connection methods has its own advantages and disadvantages. For example, while bolted connections are convenient to construct, they can lead to connection failure due to insufficient preload or loosening. Welded connections offer good rigidity, strength, and integrity, but require on-site welding, which is labor-intensive, carries high operational risks, and places high demands on weld quality. Prestressed connections do not require on-site welding, but require prestressing during construction. Insufficient prestressing can easily result in low bearing capacity. Self-locking connections, while convenient to construct, are complex to manufacture and require high precision. These connection methods make it difficult to achieve both reliable connections and sufficient working space.

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] like Figures 1 to 8As shown, a gear-driven modular steel structure detachable node in one embodiment of the present application includes two interconnected node assemblies 100, each comprising a square steel pipe column 110 and an H-shaped steel beam 120. The H-shaped steel beam 120 is mounted at a 90-degree angle to the connecting ends of the square steel pipe columns 110. The connecting ends of the square steel pipe columns 110 of the two interconnected node assemblies 100 are connected by a locking mechanism 200. To improve the reliability and strength of the connection, the two node assemblies 100 are reinforced with high-strength bolts.

[0021] Through this solution of the present embodiment, after the two node assemblies 100 are docked, the installation can be completed by connecting them using the locking mechanism 200. If disassembly is required, it is only necessary to loosen the locking mechanism 200, thereby improving the convenience of installation and disassembly.

[0022] In one embodiment of the present application, the locking mechanism 200 includes a first locking block and a second locking block. A connecting cavity is provided at the bottom of the first locking block, and a plurality of anti-shear blocks 232 are provided in the connecting cavity.

[0023] In one embodiment of the present application, the first locking block includes an upper outer sleeve 210 and an upper inner sleeve 220, and the upper inner sleeve 220 and the upper outer sleeve 210 are respectively sleeved and fixed to the inner and outer sides of the upper square steel pipe column 110, and the connecting cavity and the shear block 232 are respectively arranged in the upper inner sleeve 220, and the H-shaped steel beam 120 is fixed on the upper outer sleeve 210.

[0024] In one embodiment of the present application, the second locking block includes a lower outer sleeve 240 and a lower inner sleeve 250, and the lower inner sleeve 250 and the lower outer sleeve 240 are respectively sleeved and fixed on the inner and outer sides of the lower square steel pipe column 110, and the locking head 260 is arranged at the top of the lower inner sleeve 250, and the H-shaped steel beam 120 is fixed on the lower outer sleeve 240.

[0025] In one embodiment of the present application, the bottom surface of the upper inner sleeve 220 is recessed to form a connecting portion 231, the cavity of the connecting portion 231 is the connecting cavity, the shear block 232 is rotatably connected to the four sides of the connecting portion 231, and extends into the connecting cavity through the through hole 233 on the peripheral surface of the connecting portion 231.

[0026] In one embodiment of the present application, a sub-gear 234 is coaxially connected to the shear block 232, and a gear switch is provided through the upper outer sleeve 210, the square steel pipe column 110 and the upper inner sleeve 220, and the sub-gear 234 is driven by the gear switch.

[0027] In one embodiment of the present application, the sub-gears 234 are connected to each other via a chain 235. A mother gear 236 is coaxially connected to one of the sub-gears 234, and the gear switch meshes with the mother gear 236. The chain 235 can synchronously drive the sub-gears 234, allowing the shear block 232 to rotate synchronously and insert into the fixing slot 261 of the locking head 260, ensuring symmetry of the internal vertical force around the center of the locking head 260 (the geometric center of the square steel pipe column 110).

[0028] In one embodiment of the present application, the sub-gear 234 is coaxially connected to the main gear 236 via a connecting tube 237 , and the height of the connecting tube 237 is greater than the height of the connecting portion 231 .

[0029] In one embodiment of the present application, the gear switch includes a rotating wheel 330, a connecting shaft 320 and a driving gear 310. The connecting shaft 320 passes through the upper outer sleeve 210 and the upper inner sleeve 220. The driving gear 310 is fixed to one end of the connecting shaft 320 and engages with the mother gear 236. The rotating wheel 330 is fixed to the other end of the connecting shaft 320 and is located outside the upper outer sleeve 210.

[0030] This device utilizes gear transmission to achieve internal vertical connections within the square steel pipe column 110, offering easy installation and a clear force transmission path. The dual internal and external vertical connections ensure reliable vertical force transmission within the node. The external vertical connection can be achieved via bolts, while the internal vertical connection utilizes gears to enable externally controlled assembly and disassembly of the sleeve. Both installation and disassembly are simple and easy to operate, improving construction efficiency.

[0031] In one embodiment of the present application, a reinforcement plate 400 is provided between the square steel pipe column 110 and the H-shaped steel beam 120. The ring plates of the upper outer sleeve 210 and the lower outer sleeve 240 serve to strengthen the connection, horizontally strengthening the connection between the H-shaped steel beam 120 and the square steel pipe column 110, and vertically strengthening the connection between the upper and lower square steel pipe columns 110, thereby enhancing the structural integrity.

[0032] The installation method of the gear transmission modular steel structure detachable node includes the following steps: The square steel pipe column 110, H-shaped steel beam 120, upper inner sleeve 220, lower inner sleeve 250, upper outer sleeve 210, lower outer sleeve 240, gear switch and shear block 232 are processed in the factory; In the factory, the mother gear 236, the sub-gear 234, and the shear block 232 are installed on the upper inner sleeve 220. The sub-gear 234 is then connected via the chain 235. Finally, the square steel pipe with the reserved holes is welded together to complete the upper inner sleeve 220. The locking head 260 is welded to the lower inner sleeve 250 to complete the lower inner sleeve 250. Weld the H-shaped steel beam 120 to the upper outer sleeve 210 and the lower outer sleeve 240, and then weld the reinforcement plate 400; place the upper inner sleeve 220 inside the upper square steel pipe column 110, and then insert the upper square steel pipe column 110 between the upper inner sleeve 220 and the upper outer sleeve 210, and then fix them with one-way bolts and tension bolts; Similarly, place the lower inner sleeve 250 inside the lower square steel pipe column 110, and then insert the lower square steel pipe column 110 between the lower inner sleeve 250 and the lower outer sleeve 240, and fix them with one-way bolts and tension bolts; Insert the external gear into the external gear sleeve, and then insert it into the reserved holes of the upper outer sleeve 210, the upper square steel pipe column 110, and the upper inner sleeve 220, and weld the external gear sleeve to the upper square steel pipe column 110 to complete the upper unit processing.

[0033] After the components are transported to the site, the lower module unit is fixed first, and then the upper unit is placed; the gear switch is put on the outer gear and rotated counterclockwise until it cannot rotate, and then the upper and lower connections are reinforced with high-strength bolts.

[0034] During installation, the docking planes of the upper inner sleeve 220 and the lower inner sleeve 250 do not coincide with the docking planes of the upper and lower square steel pipe columns 110. At the same time, the docking planes of the upper outer sleeve 210 and the lower outer sleeve 240 do not coincide with the docking planes of the upper and lower square steel pipe columns 110. The horizontal weak planes are vertically staggered, thereby enhancing the horizontal shear strength, stiffness and stability of the node.

[0035] If disassembly is necessary: ​​first remove the vertical high-strength bolts, then put the gear switch on the outer gear and rotate it clockwise until it cannot rotate. You can use a crane to vertically pull up the upper module unit to complete the entire module disassembly.

[0036] According to one embodiment of the present application, the beneficial effects of using this gear-driven modular steel structure detachable node are: after the two node components are assembled, they can be locked together by simply turning a gear switch. This has the advantages of efficient and fast construction, reliable connection, clear force transmission path, environmental protection, and detachability. While ensuring connection reliability, it also provides ample construction workspace. All components can be manufactured in a factory, and installation and removal at the construction site only require high-strength bolts and gear switches, making the entire operation simple and efficient.
