[0002] Modular Integrated Construction (MIC) refers to a new building construction system in which "module units" are prefabricated in factories and reliably connected at the construction site to form an integrated whole. A module includes components such as beams and columns. A modular steel structure building is a building structure assembled from multiple modules. As an emerging construction system, modular building is fundamentally different from traditional building construction methods.

The present invention adopts a unique connection plate and connection cylinder combination design. The connection plate is fixed on the first shell, and the connection cylinder is movably sleeved outside the connection plate to preliminarily connect the first shell and the second shell. This design not only provides a flexible connection method, but also makes the steel structure more convenient and quick when disassembling and reassembling. At the same time, the first spring and the card block on the inner wall of the connection cylinder, as well as the limit block and auxiliary block on the connection plate, together constitute a reliable locking mechanism When the clamping block is locked into the limiting block under the action of the first spring, the connecting plate is firmly locked in the connecting cylinder, thereby realizing a stable connection of the steel structure. The arc-shaped guide surface formed by the contact between the auxiliary block and the limiting block facilitates unlocking the clamping block when needed, making the steel structure easy to disassemble. By introducing the limiting assembly, the depth of the pipe rack in the connecting cylinder can be accurately controlled, thereby ensuring the correctness and stability of the connection structure. This design not only improves the flexibility of the connection, but also enables the steel structure to adapt to the needs of pipe racks of different sizes and shapes. By adding components such as the second rack, connecting rod, and limiting ring, the stability and angle adjustment of the steel structure are further enhanced. The second rack is meshed with the first gear, and when the first gear rotates, it will drive the first rack and the second rack to slide at the same time, and the second rack drives the limit ring to move through the connecting rod, thereby increasing the angular stability between the second shell and the connecting cylinder.

[0034] In this embodiment, the modular steel structure consists of steel beams and wall panels for dividing spaces. The wall panels are installed on the steel beams, and the first shell 1 and the second shell 2 are respectively installed on the steel beams of the two steel structure modules. The first shell 1 and the second shell 2 are easy to assemble and disassemble through the cooperation and limitation of the connecting plate 3, the connecting tube 4, the pipe rack 7, the clamping block 6, the auxiliary block 9, the limit block 8 and the limit assembly, thereby facilitating the assembly and disassembly of the two steel structure module bodies. The first shell 1 and the second shell 2 and the structures thereon are respectively located at the two ends of the same steel beam. The two modules cooperate with each other to realize the connection of multiple steel structures, and the assembly and splicing of the structure can be realized without the use of other auxiliary tools. The connecting plate 3 (fixed on the first shell 1), as one of the main components connecting the first shell 1 and the second shell 2, cooperates with the connecting tube 4 to realize the preliminary connection, providing a stable connection foundation, and facilitating the assembly of the steel structure. The connecting tube 4 and the connecting plate 3 jointly realize the preliminary connection of the first shell 1 and the second shell 2, increasing the flexibility of the connection. , provides a detachable feature for the modular steel structure, the pipe rack 7 serves as a supporting and guiding structure, assists the cooperation between the card block 6 and the limit block 8, enhances the stability of the connection, and facilitates the alignment and locking of the card block 6 and the limit block 8, the first spring 5 provides elastic force, so that the card block 6 can automatically snap into the limit block 8 to achieve locking, providing a simple and effective locking mechanism to ensure a stable connection of the steel structure, the limit block 8 cooperates with the card block 6 to prevent the connecting plate 3 from detaching from the connecting cylinder 4, increases the reliability of the connection, and prevents the steel structure from loosening or separating when subjected to force, the auxiliary block 9 contacts the limit block 8 to form an arc-shaped guide surface, which facilitates the card block 6 to detach from the limit block 8 when needed, providing a convenient unlocking mechanism, making the steel structure easy to disassemble, the limit assembly (arranged between the connecting cylinder 4 and the second shell 2) is used to limit the depth of the pipe rack 7 into the connecting cylinder 4, ensure the correctness and stability of the connection structure, and prevent the connection from being unstable due to over-insertion or insufficient insertion, and cooperates with the limit block 8 to achieve a two-way limiting effect on the card block 6.

[0035] In a further preferred embodiment of the present invention, the limiting assembly includes: a first rack 11 slidably mounted on the second housing 2; a first gear 10 rotatably mounted on the second housing 2 for assisting the sliding of the first rack 11, the first rack 11 being engaged with the first gear 10; and a limiting plate 12 slidably mounted in the connecting tube 4 for limiting the depth of the pipe rack 7 penetrating into the connecting tube 4, the limiting plate 12 being connected to the first rack 11.

[0036] In this embodiment, the first rack 11 is meshed with the first gear 10, and by sliding, the first rack 11 can drive the limit plate 12 connected to it to move, providing a mechanism for controlling the position of the limit plate 12 through gear transmission, so that the adjustment of the position of the limit plate 12 is more accurate and convenient. The first gear 10 is used to assist the sliding of the first rack 11. When the first gear 10 rotates, it drives the first rack 11 meshed with it to slide along the second shell 2. Through gear transmission, remote control or adjustment of the position of the first rack 11 (and the connected limit plate 12) is achieved, which increases the flexibility of the structure and the convenience of operation. The limit plate 12 is used to limit the depth of the pipe rack 7 into the connecting tube 4. The position of the limit plate 12 is controlled by the first rack 11, ensuring the correct position of the pipe rack 7 in the connecting tube 4, and preventing connection problems caused by over-insertion or insufficient insertion. At the same time, through the adjustment of the limit plate 12, it can adapt to pipe racks 7 of different sizes or connection requirements.

[0037] In a further preferred embodiment of the present invention, a second rack 13 is slidably mounted on the second shell 2, the second rack 13 is engaged with the first gear 10, a connecting rod 18 is fixed on the second rack 13, and a limiting ring 17 is installed on the connecting rod 18, which is sleeved on the outside of the connecting tube 4 to increase the angular stability of the second shell 2 and the connecting tube 4, and an auxiliary structure is provided on the second shell 2 to assist the movement of the limiting ring 17.

[0038] In this embodiment, since the first gear 10 is engaged with the first rack 11 and the second rack 13 at the same time, when the first gear 10 rotates, it will drive the first rack 11 and the second rack 13 to slide at the same time. By adding the second rack 13, control or adjustment of another group of structures is achieved, which increases the diversity and functionality of the structure. In this embodiment, the second rack 13 is connected to the connecting rod 18 and the limiting ring 17, which work together to increase the angular stability between the second shell 2 and the connecting cylinder 4. The connecting rod 18 is used to connect the second rack 13 and the limiting ring 17. When the second rack 13 slides, it will drive the limiting ring 17 to move through the connecting rod 18. The connecting rod 18 serves as a transmission component, which converts the sliding of the second rack 13 into the movement of the limiting ring 17, thereby achieving the second shell 2 and the connecting cylinder 4. To adjust the stability between the connecting tubes 4, the limit ring 17 is sleeved on the outside of the connecting tube 4 to increase the angular stability between the second shell 2 and the connecting tube 4. The position of the limit ring 17 is jointly controlled by the second rack 13 and the connecting rod 18. The existence of the limit ring 17 can prevent the second shell 2 and the connecting tube 4 from rotating relative to each other when force is applied, thereby increasing the stability of the entire structure. By adjusting the position of the limit ring 17, it can adapt to connection requirements at different angles. The auxiliary structure is used to assist the movement of the limit ring 17 to ensure that the limit ring 17 can slide smoothly and freely on the second shell 2. The existence of the auxiliary structure can reduce the friction and resistance of the limit ring 17 during movement, thereby improving the overall performance and durability of the structure. At the same time, it can also ensure that the limit ring 17 can be accurately positioned at the required position.

[0039] In a further preferred embodiment of the present invention, the auxiliary structure includes a support frame 14 fixed on the second shell 2, a second gear 15 rotatably mounted on the support frame 14, the second gear 15 is engaged with the first rack 11, a third rack 16 is slidably mounted on the support frame 14 and engaged with the second gear 15, and a connecting frame 34 for connecting the third rack 16 and the limiting ring 17 is installed between the third rack 16 and the limiting ring 17.

[0040] In this embodiment, the support frame 14 serves as the installation base for the second gear 15 and the third rack 16, providing a stable support structure, ensuring that the second gear 15 and the third rack 16 can rotate and slide smoothly and accurately. When the first rack 11 slides, it drives the second gear 15 to rotate. The second gear 15 serves as a transmission component, converting the sliding of the first rack 11 into the rotation of the second gear 15, and then adjusting the position of the limit ring 17 through the third rack 16. This design increases the flexibility and adjustability of the structure. The third rack 16 serves as the end of the transmission chain, converting the rotation of the second gear 15 into its own sliding, and then achieving precise adjustment of the position of the limit ring 17 through the connecting frame 34. The connecting frame 34 serves as an extension of the transmission component, converting the sliding of the third rack 16 into the movement of the limit ring 17, thereby achieving precise adjustment of the angular stability between the second shell 2 and the connecting cylinder 4.

[0041] In a further preferred embodiment of the present invention, a slide groove 23 is provided on the pipe rack 7, and a slide plate 24 connected to the auxiliary block 9 is slidably installed in the slide groove 23. A second spring 25 connected to the slide plate 24 is installed in the pipe rack 7, and the second spring 25 is used to assist the auxiliary block 9 to move away from the limit block 8.

[0042] In this embodiment, the chute 23 serves as a sliding track for the slide plate 24, ensuring that the slide plate 24 (and the auxiliary block 9 connected thereto) can move smoothly and accurately. When the slide plate 24 slides within the chute 23, it drives the auxiliary block 9 with it. The slide plate 24 acts as a transmission component, converting the guiding effect of the chute 23 into the movement of the auxiliary block 9. This design makes the movement of the auxiliary block 9 more stable and controllable. The presence of the second spring 25 provides a reset mechanism for the auxiliary block 9. When the external force disappears, the second spring 25 drives the slide plate 24 (and the auxiliary block 9) back to the initial position, preparing for the next locking or unlocking operation. At the same time, the second spring 25 also increases the stability and durability of the structure.

[0043] In a further preferred embodiment of the present invention, a second retaining ring 20 connected to the first rack 11 is slidably mounted on the second shell 2, and a first retaining ring 19 connected to the second rack 13 is slidably mounted on the second shell 2, and both the first retaining ring 19 and the second retaining ring 20 are provided with a slider 21 slidably connected to the second shell 2.

[0044] In this embodiment, the first snap ring 19 is slidably connected to the second shell 2 through the slider 21 thereon. The first snap ring 19 serves as a connecting component to firmly connect the second rack 13 to the second shell 2, while allowing the second rack 13 to slide along the second shell 2. This design not only enhances the stability of the structure, but also ensures that the second rack 13 can move freely. The function of the second snap ring 20 is similar to that of the first snap ring 19. It firmly connects the first rack 11 and the second shell 2, while allowing the first rack 11 to slide along the second shell 2. This design further enhances the stability and flexibility of the structure. The slider 21 provides a smooth, low-friction sliding surface, so that the first snap ring 19 and the second snap ring 20 can easily slide on the second shell 2. This design not only reduces the resistance during movement, but also enhances the durability of the structure.

[0045] In a further preferred embodiment of the present invention, a fixing plate 27 is fixed on the second shell 2, and a threaded rod 28 is threadedly installed on the fixing plate 27. One end of the threaded rod 28 is rotatably installed with a limiting clamping plate 29 that is in sliding contact with the outer wall of the second shell 2. The limiting clamping plate 29 can be clamped outside the first gear 10 to stabilize the angle of the first gear 10. The end of the threaded rod 28 away from the limiting clamping plate 29 is provided with an adjustment block 30 for providing an operating grip point.

[0046] In this embodiment, the fixing plate 27 provides a stable support point, allowing the threaded rod 28 to be stably mounted on the second housing 2. The threaded rod 28 serves as a transmission component, and the position of the limit plate 29 can be adjusted by rotating it. This design allows the limit plate 29 to be flexibly clamped outside the first gear 10, thereby stabilizing the angle of the first gear 10. The presence of the limit plate 29 ensures that the first gear 10 can maintain a stable angle when needed, preventing it from rotating accidentally. This design improves the stability and reliability of the transmission system. The adjustment block 30 allows the installer to easily rotate the threaded rod 28 to adjust the position of the limit plate 29. This design improves the operability of the structure. When the limit plate 29 is clamped on the teeth of the first gear 10, the first gear 10 cannot rotate normally. Accordingly, the first rack 11, the second rack 13, and the third rack 16 are all in a stable state, thereby stabilizing the position of the limit ring 17 and the limit plate 12, ensuring the stability of the connection between the first housing 1 and the second housing 2.

[0047] In a further preferred embodiment of the present invention, the inner wall of the limit ring 17 is inlaid with balls 31 that are in contact with the outer wall of the connecting tube 4 for reducing friction, the connecting tube 4 is provided with an opening 22 that allows the first rack 11 and the second rack 13 to pass through, and the first gear 10 is installed with a pointer 35 for assisting in indicating the position of the limit plate 12.

[0048] In this embodiment, the presence of the ball 31 significantly reduces the friction between the limit ring 17 and the connecting tube 4, making the relative movement between the two freer. This design not only reduces wear, but also improves the durability and service life of the structure. The design of the opening 22 allows the first rack 11 and the second rack 13 to freely pass through the connecting tube 4 and engage with transmission components such as gears. This design not only ensures the normal operation of the transmission system, but also increases the flexibility and adjustability of the structure. The presence of the pointer 35 allows the installer to intuitively understand the current position of the limit plate 12 (and the first rack 11 connected to it). This design improves the recognizability and operability of the structure, allowing the installer to operate and monitor more conveniently.

[0049] In a further preferred embodiment of the present invention, a guide groove 32 is provided on the inner wall of the connecting cylinder 4, and a guide block 33 fixedly connected to the limit plate 12 is slidably installed in the guide groove 32, and the guide block 33 cooperates with the guide groove 32 to limit the moving path of the limit plate 12.

[0050] In this embodiment, the guide groove 32 provides a clear sliding path, ensuring that the guide block 33 (and the limit plate 12 connected thereto) can move smoothly and accurately along the predetermined direction. This design not only enhances the stability of the structure, but also improves the controllability of the movement of the limit plate 12. When the guide block 33 slides in the guide groove 32, it drives the limit plate 12 to move together. The guide block 33 serves as a connecting component, converting the guiding effect of the guide groove 32 into the movement of the limit plate 12. This design not only simplifies the complexity of the structure, but also ensures that the limit plate 12 can move smoothly along the predetermined path. At the same time, the sliding fit between the guide block 33 and the guide groove 32 also reduces friction and wear, thereby improving the durability of the structure.

[0051] In a further preferred embodiment of the present invention, a positioning block 36 for stabilizing the installation angle of the connecting plate 3 is slidably installed in the connecting tube 4, and the positioning block 36 is fixedly connected to the connecting plate 3. A handle 37 for providing an operating grip point is fixed on the connecting plate 3, and the handle 37 is also used to increase the stability of the connection angle between the first shell 1 and the connecting plate 3. The first spring 5 and the second spring 25 are both provided with a limiting telescopic rod 26 for limiting the telescopic path of the first spring 5 and the second spring 25.

[0052] In this embodiment, the presence of the positioning block 36 is used to stabilize the installation angle of the connecting plate 3 to prevent it from shifting or rotating during use. The sliding cooperation between the positioning block 36 and the connecting tube 4 can ensure that the connecting plate 3 can maintain a predetermined angle during installation, thereby improving the stability and reliability of the entire structure. This design not only simplifies the complexity of the structure, but also improves the installation efficiency. The handle 37 provides an operating grip point. The handle 37 also increases the stability of the connection angle between the first shell 1 and the connecting plate 3 through its structural design and position layout. The presence of the handle 37 enables the installer to easily hold and operate the connecting plate 3, improves the operability of the structure, and prevents the connection from loosening or deformation due to external force. The presence of the limiting telescopic rod 26 ensures that the first spring 5 and the second spring 25 can move along a predetermined path when telescoping, thereby improving the stability and controllability of the structure. This design not only prevents the spring from shifting or twisting during the telescoping process, but also extends the service life of the spring.

[0053] In summary, compared with the relevant technology, this device adopts a modular construction concept to connect the two steel structure modules together by connecting the first shell 1 and the second shell 2. The present invention adopts a unique combination design of connecting plate 3 and connecting cylinder 4. The connecting plate 3 is fixed on the first shell 1, and the connecting cylinder 4 is movably sleeved outside the connecting plate 3 for preliminarily connecting the first shell 1 and the second shell 2. This design not only provides a flexible connection method, but also makes the steel structure more convenient and quick to disassemble and reassemble.
