Description

Technical Field

[0001] This utility model relates to the field of building steel structure technology, and in particular to a prefabricated steel structure building module connector. Background Technology

[0002] Prefabricated buildings refer to buildings assembled on-site using prefabricated components. The advantages of this type of construction include rapid construction speed, less susceptibility to weather conditions, labor savings, and improved building quality. Modular buildings, as an emerging building system, have a high prefabrication rate and have been developed for many years abroad. They offer significant advantages in improving project quality, shortening construction time, saving manpower and resources, and protecting the environment, meeting the requirements for industrialized construction and green building development. However, most of the construction work in prefabricated buildings is completed in factories. In existing related technologies, the connections between prefabricated modules may be too rigid, lacking buffering during vibrations, leading to stress concentration at the connection points, easy damage, and even causing overall structural shaking or failure. Utility Model Content

[0003] To address the issues of insufficient stability and shock absorption in the connections between prefabricated steel structure building modules under vibration conditions in existing technologies, this utility model provides a connector for prefabricated steel structure building modules.

[0004] The technical solution adopted in this utility model is:

[0005] A prefabricated steel structure building module connector includes a first building module and a second building module. The first building module includes a first crossbeam and a first column, and the second building module includes a second crossbeam and a second column. A crossbeam damping mechanism is connected between adjacent first crossbeams and second crossbeams, and a column damping mechanism is connected between adjacent first columns and second columns.

[0006] The beam damping mechanism includes a beam damping component, which is detachably connected to the first beam and the second beam respectively. The column damping mechanism includes a column damping component, which is detachably connected to the first column and the second column respectively. Both the beam damping component and the column damping component are used to form a vibration gap by supporting the first building module and the second building module.

[0007] Furthermore, a detachable beam locking mechanism is connected between the beam damper and the first and second beams. The beam locking mechanism includes a beam locking rod, which passes through the first beam, the beam damper, and the second beam in sequence. Both ends of the beam locking rod are threadedly connected to a beam locking head. The beam locking rod is used to lock the first beam, the beam damper, and the second beam by applying pressure in opposite directions to the beam locking heads at both ends.

[0008] Furthermore, the crossbeam damper has a hollow cylindrical structure, and the height of the crossbeam damper is less than or equal to the height of the connection and mounting surface with the first or second crossbeam.

[0009] Furthermore, the cross-section of the beam damper is I-shaped, and the height of the side plate of the beam damper that contacts the first or second beam is less than or equal to the height of the connection mounting surface with the first or second beam.

[0010] Furthermore, a detachable column locking mechanism is connected between the column damping component and the first and second columns. The column locking mechanism includes a column locking rod, which passes through the first column, the column damping component, and the second column in sequence. Both ends of the column locking rod are threadedly connected and respectively provided with column locking heads. The column locking rod is used to lock the first column, the column damping component, and the second column by applying pressure in opposite directions to the column locking heads at both ends.

[0011] Furthermore, the column damping component has a hollow cylindrical structure, and the width of the column damping component is less than or equal to the width of the connection and mounting surface with the first column or the second column.

[0013] Furthermore, both the beam damper and the column damper are provided with reinforcing ribs, which are used to provide support to the first building module and the second building module through the beam damper and the column damper.

[0014] The beneficial effects of this utility model are:

[0015] This invention addresses stability and cushioning issues during vibration by establishing beam and column damping mechanisms between the beams and columns of adjacent building modules, forming a targeted damping system. During operation, when the building is subjected to vibration, the first and second building modules tend to shift relative to each other. The beam and column damping components function at the beam-column connection points.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] A type of prefabricated steel structure building module connector, such as Figures 1-3As shown, the system includes a first building module 1 and a second building module 2. The first building module 1 includes a first crossbeam 3 and a first column 5. The second building module 2 includes a second crossbeam 4 and a second column 6. A crossbeam damping mechanism 7 connects adjacent first crossbeams 3 and second crossbeams 4, and a column damping mechanism 8 connects adjacent first columns 5 and second columns 6. The crossbeam damping mechanism 7 includes a crossbeam damping component 13, which is detachably connected to the first crossbeam 3 and the second crossbeam 4. The column damping mechanism 8 includes a column damping component 14, which is detachably connected to the first column 5 and the second column 6. Both the crossbeam damping component 13 and the column damping component 14 are used to form a vibration gap between the first building module 1 and the second building module 2 by supporting them.

[0026] During the installation of prefabricated steel structure building modules, the first beam 3 of the first building module 1 is aligned with the second beam 4 of the second building module 2. Beam damping components 13 are installed between adjacent first beams 3 and second beams 4, and fixed using a detachable connection. Simultaneously, the first column 5 is aligned with the second column 6, and column damping components 14 are installed between adjacent first columns 5 and second columns 6, also using a detachable connection. After assembly, the beam damping components 13 and column damping components 14 are supported between the beams and columns of the two building modules, naturally forming a vibration gap. When the building is subjected to external vibration, the vibration gap provides space for relative movement between the two modules. The beam damping components 13 and column damping components 14 buffer vibration energy through their own support, reducing direct rigid collisions between the first building module 1 and the second building module 2. The specific principle can be referenced from friction plate damping: based on frictional energy dissipation and enhanced structural damping, friction is generated through the relative sliding between steel plates, converting external vibration energy into heat energy and other forms of dissipation, thereby reducing the vibration response of the structure.

[0027] The connection structure of this utility model makes the connection of prefabricated building modules more convenient, and the detachable connection facilitates later maintenance and replacement. The presence of vibration gaps effectively improves the overall seismic performance of the building, meeting the needs of rapid installation and safe use in prefabricated buildings. During implementation, it is necessary to ensure that the beam damping component 13 and the column damping component 14 are installed accurately, and that the connection with the beams and columns is firm and reliable. It is also essential to ensure that the vibration gap size is uniform and to avoid a decrease in damping effect or structural instability due to improper installation.

[0028] The detachable connection of the shock absorber of this utility model can adopt structures such as bolt connection, pin connection, and slot limit fit connection. The specific settings can be selected according to the construction needs and combined with the above-mentioned connection structures in the existing technology and directly applied to the detachable connection of this utility model, so as to achieve quick assembly and disassembly.

[0029] Example 2

[0030] This embodiment is based on the foregoing embodiments. In this embodiment, as follows: Figure 2 As shown, a detachable beam locking mechanism is connected between the crossbeam damper 13 and the first crossbeam 3 and the second crossbeam 4. The beam locking mechanism includes a beam locking rod 9, which passes through the first crossbeam 3, the crossbeam damper 13, and the second crossbeam 4 in sequence. Both ends of the beam locking rod 9 are connected by threads and are respectively provided with beam locking heads 10. The beam locking rod 9 is used to lock the first crossbeam 3, the crossbeam damper 13, and the second crossbeam 4 by the pressure applied in opposite directions by the beam locking heads 10 at both ends.

[0031] In one preferred embodiment, the crossbeam damper 13 has a hollow cylindrical structure, and the height of the crossbeam damper 13 is less than or equal to the height of the connection and mounting surface with the first crossbeam 3 or the second crossbeam 4.

[0032] In one preferred embodiment, the cross-section of the beam damper 13 is I-shaped, and the height of the side plate of the beam damper 13 that contacts the first beam 3 or the second beam 4 is less than or equal to the height of the connection mounting surface with the first beam 3 or the second beam 4.

[0033] When installing the crossbeam damper 13, first place it in the preset position between the first crossbeam 3 and the second crossbeam 4. Then, pass the crossbeam locking rod 9 through the corresponding mounting holes of the first crossbeam 3, the crossbeam damper 13, and the second crossbeam 4 in sequence. Next, screw the crossbeam locking head 10 into both ends of the crossbeam locking rod 9. By rotating the crossbeam locking head 10, apply pressure in opposite directions to tightly lock the first crossbeam 3, the crossbeam damper 13, and the second crossbeam 4 into a single unit. The crossbeam damper 13 can adopt a hollow cylindrical structure, and its height should not exceed the height of the connecting mounting surface of the first crossbeam 3 or the second crossbeam 4 (e.g., ...). Figure 2 The "h" in the diagram represents the height of the crossbeam damper 13. Alternatively, an I-shaped cross-section can be used, with the height of the side plate in contact with the crossbeam not exceeding the height of the mounting surface. During operation, the crossbeam locking mechanism ensures a stable connection through the cooperation of the locking rod and locking head, preventing the damper from loosening during vibration. The hollow cylindrical structure reduces weight while maintaining support strength, while the I-shaped structure enhances lateral stability. The height setting prevents the damper from protruding from the mounting surface and affecting the assembly of other components, while also effectively concealing the connection structure within the building module, without affecting the facade. During implementation, it is necessary to ensure the precise penetration position of the crossbeam locking rod 9 and the moderate tightening force of the crossbeam locking head 10. This ensures a secure connection while avoiding excessive compression that could damage the damper, and also controls the height of the damper to meet the requirements of the mounting surface.

[0034] Currently, the construction methods and prefabrication levels in steel structure connection technologies are still not high. To achieve a high degree of prefabrication in modular buildings, all construction work, except for the connection and fixing of different modules in the prefabricated steel structure, must be completed in the factory. In existing technologies, after the modules are assembled, the joints need to be redecorated and hidden, which does not meet the requirements of factory prefabrication. The connection method between modules in this utility model allows all construction work, except for the connection and fixing of different modules, to be completed in the factory, realizing a high degree of prefabrication in prefabricated buildings. During on-site construction, operations only need to be carried out inside the building modules, without affecting the exterior decoration, thus improving work efficiency.

[0035] Example 3

[0036] This embodiment is based on the foregoing embodiments. In this embodiment, as follows: Figure 3 , Figure 4 As shown, a detachable column locking mechanism is connected between the column damping component 14 and the first column 5 and the second column 6. The column locking mechanism includes a column locking rod 11, which passes through the first column 5, the column damping component 14, and the second column 6 in sequence. Both ends of the column locking rod 11 are threadedly connected to a column locking head 12. The column locking rod 11 is used to lock the first column 5, the column damping component 14, and the second column 6 by applying pressure in opposite directions to the column locking heads 12 at both ends.

[0037] In one preferred embodiment, the column damping member 14 has a hollow cylindrical structure, and the width of the column damping member 14 is less than or equal to the width of the connection and mounting surface with the first column 5 or the second column 6.

[0038] In one preferred embodiment, the cross-section of the column damping member 14 is I-shaped, and the width of the side plate of the column damping member 14 that contacts the first column 5 or the second column 6 is less than or equal to the width of the connection and mounting surface with the first column 5 or the second column 6.

[0039] When installing the column damper 14, place it between the first column 5 and the second column 6. Then, pass the column locking rod 11 sequentially through the mounting holes of the first column 5, the column damper 14, and the second column 6. Screw the column locking heads 12 into both ends of the column locking rod 11. Apply relative pressure by rotating the locking heads to ensure a tight lock. The column damper 14 can be a hollow cylindrical structure, and its width does not exceed the width of the mounting surface connecting the first column 5 or the second column 6 (e.g., ...). Figure 4(The 'd' marked in the figure represents the width of the column damper 14). Alternatively, an I-shaped cross-section can be used, with the width of the side plate in contact with the column not exceeding the width of the mounting surface. During operation, the column locking mechanism, through the cooperation of the locking rod and locking head, ensures a stable column connection and resists longitudinal forces caused by vibration. The hollow cylindrical structure provides longitudinal support while reducing weight, the I-shaped structure enhances vertical stability, and the width setting prevents the damper from protruding from the mounting surface and interfering with the installation of other structures. During implementation, it is necessary to ensure that the column locking rod 11 penetrates accurately and that the column locking head 12 is tightened appropriately to prevent loosening or excessive compression that could damage the damper. Simultaneously, the width of the column damper 14 must be controlled to meet the requirements of the mounting surface to ensure the overall structural assembly accuracy.

[0040] In embodiments 2 and 3 above, the locking rod and locking head can be locked by connecting a bolt rod with threads at both ends and a nut, as shown in the following structure. Figure 2 , Figure 3 As shown.

[0041] Example 4

[0042] This embodiment is based on the aforementioned embodiment. In this embodiment, both the beam damper 13 and the column damper 14 are provided with reinforcing ribs. The reinforcing ribs are used to provide support force to the first building module 1 and the second building module 2 through the beam damper 13 and the column damper 14. Both the beam damper 13 and the column damper 14 are equipped with reinforcing ribs during manufacturing. The reinforcing ribs can be fixedly connected to the damper body or integrally formed. During the assembly of the building modules, the dampers with reinforcing ribs are installed between the beam and the column, respectively, and fixed by the aforementioned locking mechanism. When the building is subjected to vibration or load, the force transmitted by the beam and the column acts on the damper. At this time, the reinforcing ribs play a role, enhancing the overall stiffness of the damper through their own structural strength, enabling the damper to be stably supported between the two building modules and uniformly transmit support force to the first building module 1 and the second building module 2. The presence of reinforcing ribs prevents excessive deformation or damage to the damper under stress, ensuring the stability of the vibration gap and ensuring a continuous and reliable damping effect. Meanwhile, the reinforcing ribs enhance the load-bearing capacity of the damping components, extend their service life, and enable the connectors to withstand various loads and vibrations during long-term building use. During implementation, the arrangement of the reinforcing ribs should be uniform and reasonable, maximizing their reinforcing effect without excessively increasing the weight of the damping components or affecting their installation space, ensuring that the overall structure of the reinforcing ribs and damping components is compatible with the stress requirements of the building module. For example, when using a hollow cylindrical damping component, the reinforcing ribs are placed on the inner wall of the cylinder; when using an I-shaped damping component, the reinforcing ribs are symmetrically arranged on opposite sides within the damping component. The specific shape and distribution of the reinforcing ribs can be achieved using existing reinforcing ribs from related technologies, and will not be elaborated further here.

[0043] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
