Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to an expandable modular steel structure building component connection device. Background Technology

[0002] In the field of modern architecture, steel structure buildings have been widely used due to their significant advantages such as high strength, light weight, and short construction period. With the continuous development of the construction industry and the constant updating of architectural concepts, higher requirements have been placed on the performance and sustainability of steel structure buildings, making the performance and characteristics of steel structure component connection devices crucial.

[0003] Existing steel structure component connection methods are diverse, among which traditional welding connections offer high connection strength and can ensure the stability of building structures to a certain extent. However, this connection method has revealed many drawbacks in practical applications. On the one hand, welding construction requires specialized welding equipment and operators with high levels of professional skills, which undoubtedly increases construction costs and raises the technical threshold. On the other hand, welding operations are time-consuming, significantly impacting construction progress. More importantly, once welding is completed, subsequent renovations or recycling of the building will face immense difficulties in dismantling, not only consuming substantial manpower and resources but also potentially causing irreversible damage to the building structure, severely restricting the sustainable development of the building.

[0004] Another common connection method is bolted connection, which offers some convenience during installation compared to welding, thus improving construction efficiency to a certain extent. However, when a building is subjected to dynamic loads for extended periods, bolted connections are prone to loosening, requiring regular maintenance to ensure reliability. This undoubtedly increases the building's operating costs and maintenance workload. Furthermore, bolted connections are susceptible to stress concentration under load, which can negatively impact connection stability and threaten the overall safety of the building, potentially leading to serious safety hazards, especially during natural disasters such as earthquakes. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides an expandable modular steel structure building component connection device. This device solves the problems of complex construction, poor connection stability, and inconvenient maintenance and modification of existing steel structure component connection devices, achieving efficient, stable, expandable, and easily disassembled steel structure component connections.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An expandable modular steel structure building component connection device is disclosed. This device is used for connecting vertical and horizontal steel structures, including a connecting seat, a fixing mechanism, and a clamping mechanism. The connecting seat adopts a "T"-shaped structure and has a slot for connecting the horizontal steel structure. The fixing mechanism is disposed on the connecting seat and extends through the slot. The clamping mechanism is disposed on the connecting seat and extends into the slot for clamping and fixing the connected steel structure.

[0008] The fixing mechanism includes a first anti-loosening bolt and a first anti-loosening nut. Several through holes are provided on the connecting seats on both sides of the slot. The first anti-loosening bolt passes through the through holes, and the first anti-loosening nut is connected to the first anti-loosening bolt.

[0009] The through hole is configured to match the first anti-loosening bolt.

[0010] The connector is provided with mounting holes for connecting to a vertical steel structure.

[0011] The slot has a first anti-slip tooth on its inner side.

[0012] The clamping mechanism includes a first oblique tooth groove, a fastening plate, and a driving component. The first oblique tooth groove is disposed on the inner side of the slot. The fastening plate is movably disposed in the slot. The driving component is disposed on the side of the connecting seat that is connected to the vertical steel structure, and the driving component abuts against the fastening plate.

[0013] The fastening plate has a second oblique groove on the side near the first oblique groove, and the second oblique groove is matched with the first oblique groove.

[0014] The fastening plate has a second anti-slip tooth on the side away from the first oblique tooth groove.

[0015] The driving component includes an elastic steel plate, a driving plate, a second anti-loosening bolt, and a second anti-loosening nut. The connecting seats on both sides of the slot are provided with guide grooves that communicate with the first oblique tooth groove. The elastic steel plate is slidably disposed in the guide groove. One end of the elastic steel plate is fixedly connected to the fastening plate, and the other end is fixedly connected to the driving plate. A second anti-loosening bolt is inserted into the driving plate, penetrating the connecting seat and the vertical steel structure. The second anti-loosening nut is threadedly fitted onto the second anti-loosening bolt.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The clamping mechanism design ensures the stability of the connection between the horizontal steel structure and the connector. It eliminates the need for complex welding operations, reducing construction difficulty and cost, and facilitating disassembly for later modifications and maintenance. The initial clamping force, combined with the bolts, enhances the connection strength, adapting to various load conditions and ensuring the safety of the building structure. The second anti-slip tooth increases the friction between the fastening plate and the horizontal steel structure, further improving the connection's stability and preventing relative slippage due to vibrations and dynamic loads during long-term use, thus ensuring the reliability of the connection device. The first anti-slip tooth effectively increases the friction between the slot and the horizontal steel structure. When the horizontal steel structure is inserted into the slot, the first anti-slip tooth contacts the surface of the horizontal steel structure, increasing the surface roughness. This better prevents the horizontal steel structure from sliding within the slot when the connection is subjected to various loads, enhancing connection stability. This achieves efficient, stable, expandable, and easily disassembled steel structure component connections. Attached Figure Description

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0026] like Figures 1 to 5 As shown, an expandable modular steel structure building component connection device is used for connecting vertical and horizontal steel structures. The device includes a connecting seat 1, a fixing mechanism 2, and a clamping mechanism 3. The connecting seat 1 adopts a "T"-shaped structure and has a slot 11 for connecting the horizontal steel structure. The fixing mechanism 2 is mounted on the connecting seat 1 and extends through the slot 11. The clamping mechanism 3 is mounted on the connecting seat 1 and extends into the slot 11 to clamp and fix the connected steel structure. The design of the fixing mechanism 2 and the clamping mechanism 3 ensures the stability of the connection between the horizontal steel structure and the connecting seat 1. It eliminates the need for complex welding operations, reducing construction difficulty and cost, and facilitates disassembly for later modification and maintenance. Simultaneously, the initial clamping force, combined with the bolts, enhances the connection strength, adapting to various load conditions and ensuring the safety of the building structure.

[0027] The T-shaped structure provides better structural stability and mechanical performance for the connector 1. When connected to the vertical steel structure, it effectively disperses the forces from the horizontal steel structure, avoids stress concentration, and enhances the reliability of the entire connection device under complex stress conditions. Simultaneously, the T-shaped structure is more spatially compatible with other components, facilitating scalable modular design. The horizontal portion of the T-shape increases the contact area with the vertical steel structure, evenly distributing the force across the vertical steel structure under various loads, reducing single-point stress. The vertical portion of the T-shape is used to create the slot 11, which, in conjunction with the horizontal steel structure, its unique shape can, to some extent, limit the horizontal displacement of the horizontal steel structure, providing stable support.

[0028] Preferably, the fixing mechanism 2 includes a first anti-loosening bolt 21 and a first anti-loosening nut 22. Several through holes 13 are provided on the connecting seats 1 on both sides of the slot 11. The first anti-loosening bolt 21 passes through the through holes 13, and the first anti-loosening nut 22 is connected to the first anti-loosening bolt 21. When the horizontal steel structure is inserted into the slot 11, the position of the horizontal steel structure is fixed by tightening the first anti-loosening bolt 21 and the first anti-loosening nut 22.

[0029] Preferably, the through hole 13 is matched with the first anti-loosening bolt 21.

[0030] Preferably, the connector 1 is provided with mounting holes 12 for connecting to the vertical steel structure. This facilitates precise fixing of the connector 1 to the desired position on the vertical steel structure. Connection is achieved by passing bolts through the mounting holes 12, simplifying the operation and making the installation process quick and efficient. This ensures the accuracy and firmness of the connection between the connector 1 and the vertical steel structure, improving construction efficiency and the overall quality of the building structure. Construction personnel can place the connector 1 at the predetermined position on the vertical steel structure according to the architectural design requirements, aligning the mounting holes 12 on the connector 1 with the pre-drilled holes on the vertical steel structure. Then, the bolts are inserted into the mounting holes 12, and by tightening the nuts, the axial tension of the bolts secures the connector 1 tightly to the vertical steel structure, forming a stable connection structure.

[0031] Preferably, the inner surface of the slot 11 is provided with a first anti-slip tooth 111. This effectively increases the friction between the slot 11 and the horizontal steel structure. When the horizontal steel structure is inserted into the slot 11, the first anti-slip tooth 111 contacts the surface of the horizontal steel structure, increasing the roughness of the contact surface. When the connection is subjected to various loads, it can better prevent the horizontal steel structure from sliding within the slot 11, thus enhancing the stability of the connection. When the horizontal steel structure is inserted into the slot 11, the first anti-slip tooth 111 fits tightly against the surface of the horizontal steel structure. Under stress, the tips of the first anti-slip tooth 111 embed into the surface of the horizontal steel structure to a certain depth, increasing the friction that hinders its sliding.

[0032] Preferably, the clamping mechanism 3 includes a first oblique tooth groove 31, a fastening plate 32, and a driving member 34. The first oblique tooth groove 31 is disposed on the inner side of the slot 11, the fastening plate 32 is movably disposed in the slot 11, and the driving member 34 is disposed on the side of the connecting seat 1 connected to the vertical steel structure. The driving member 34 abuts against the fastening plate 32.

[0033] Preferably, a second oblique groove 33 is provided on the side of the fastening plate 32 near the first oblique groove 31, and the second oblique groove 33 is matched with the first oblique groove 31.

[0034] Preferably, a second anti-slip tooth 321 is provided on the side of the fastening plate 32 away from the first oblique tooth groove 31. The second anti-slip tooth 321 increases the friction between the fastening plate 32 and the horizontal steel structure, further improving the stability of the connection and preventing relative sliding between the horizontal steel structure and the fastening plate 32 due to various vibrations, dynamic loads, and other factors during long-term use, thereby ensuring the reliability of the connection device. When the fastening plate 32 moves towards and clamps the horizontal steel structure under the action of the driving member 34, the second anti-slip tooth 321 on the fastening plate 32 makes close contact with the surface of the horizontal steel structure. These anti-slip teeth increase the roughness of the contact surface, increase the friction, and effectively hinder the movement tendency of the horizontal steel structure.

[0035] Preferably, the driving component 34 includes an elastic steel plate 342, a driving plate 343, a second anti-loosening bolt 344, and a second anti-loosening nut 345. The connecting seats 1 on both sides of the slot 11 are provided with guide grooves 341 communicating with the first oblique tooth groove 31. The elastic steel plate 342 is slidably disposed within the guide groove 341. One end of the elastic steel plate 342 is fixedly connected to the fastening plate 32, and the other end is fixedly connected to the driving plate 343. A second anti-loosening bolt 344, penetrating the connecting seat 1 and the vertical steel structure, is inserted into the driving plate 343. The second anti-loosening nut 345 is threaded onto the second anti-loosening bolt 344. By adjusting the second anti-loosening bolt 344 and the second anti-loosening nut 345, the clamping degree of the fastening plate 32 can be precisely controlled, adapting to the connection of steel structure components of different specifications and requirements, thus enhancing the versatility and practicality of the connection device. Rotating the second anti-loosening bolt 344 causes it to move within the holes on the connecting seat 1 and the vertical steel structure. Due to the action of the second anti-loosening nut 345, the drive plate 343 moves along with the second anti-loosening bolt 344. The drive plate 343 drives the elastic steel plate 342, which is fixedly connected to it, to move. The elastic steel plate 342, in turn, drives the fastening plate 32 to slide within the guide groove 341. Under the meshing action of the first oblique tooth groove 31 and the second oblique tooth groove 33, the fastening plate 32 is displaced towards the horizontal steel structure, achieving a clamping action.

[0036] Construction workers can place the connecting seat 1 at a predetermined position on the vertical steel structure according to the architectural design requirements, aligning the mounting hole 12 on the connecting seat 1 with the reserved hole on the vertical steel structure. Then, bolts are inserted into the mounting holes 12, and by tightening the nuts, the axial tension of the bolts is used to firmly fix the connecting seat 1 to the vertical steel structure, forming a stable connection structure. A first anti-loosening bolt 21 is provided through the through hole 13, and a first anti-loosening nut 22 is connected to the first anti-loosening bolt 21. After the horizontal steel structure is inserted into the slot 11, the position of the horizontal steel structure is fixed by tightening the first anti-loosening bolt 21 and the first anti-loosening nut 22. The driving component is installed on the connecting seat 1, and the tightness of the fastening plate 32 can be precisely controlled by adjusting the second anti-loosening bolt 344 and the second anti-loosening nut 345, adapting to the connection of steel structure components of different specifications and requirements, thus enhancing the versatility and practicality of the connection device. Rotating the second anti-loosening bolt 344 causes it to move within the holes on the connecting seat 1 and the vertical steel structure. Due to the action of the second anti-loosening nut 345, the drive plate 343 moves along with the second anti-loosening bolt 344. The drive plate 343 drives the elastic steel plate 342, which is fixedly connected to it, to move. The elastic steel plate 342, in turn, drives the fastening plate 32 to slide within the guide groove 341. Under the meshing action of the first oblique tooth groove 31 and the second oblique tooth groove 33, the fastening plate 32 is displaced towards the horizontal steel structure, achieving a clamping action.

[0037] The above description only details the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
