Description

Technical Field

[0001] The present invention relates to the field of prefabricated subway station structural engineering, and in particular to a buffering and vibration isolation device for connecting beams and columns of prefabricated subway stations. Background Art

[0002] Urban rail transit is a high-capacity public transportation infrastructure and a backbone transportation mode for cities to guide and carry low-carbon travel. Currently, my country's urban rail transit is still in a stage of rapid development and continues to grow. The development of prefabricated subway station structure technology can shorten construction time, achieve full, efficient, and intensive utilization of land resources, improve socioeconomic benefits and residents' quality of life, and contribute to the sustainable development of cities. In actual projects, the design of prefabricated subway stations must consider the impact of seismic effects to ensure the safety of subway stations and superstructures under earthquakes. Furthermore, the vibration generated by subway trains can be transmitted through the subway stations to buildings above, causing vibrations in these buildings and generating secondary noise, which has a significant impact on the work and lives of people in these buildings. Therefore, it is necessary to implement vibration isolation measures to ensure the safety and comfort of buildings above the subway.

[0003] The beam-column connection structure of traditional subway stations is usually relatively simple and direct, mostly using a rigid connection method, that is, the beams are directly fixed to the columns through welding, bolting, etc., to form a relatively stable overall frame structure. However, the traditional rigid connection method lacks effective buffering and vibration isolation design. When the subway station is subjected to external dynamic loads such as earthquakes and vibrations generated by subway trains, the beam-column connection will directly bear huge impact and vibration forces, which can easily lead to stress concentration, causing serious damage such as cracks, deformation, and even fractures in the beam-column structure, greatly reducing the safety and stability of the subway station. Moreover, the rigid connection cannot effectively isolate the transmission of vibration, which may cause vibration to spread in the structure, affecting people's comfort and the normal operation of precision instruments and equipment.

[0022] See also Figure 1-Figure 5 The embodiment of the present application provides a buffering and vibration isolation device for connecting beams and columns of an assembled subway station, comprising: a base plate 1, a frame 2, a cross bar 3, a longitudinal bar 4, a fixing mechanism, a base column 5, a column 6, a longitudinal vibration isolation mechanism, a transverse vibration isolation mechanism and a cross beam 7. The base plate 1 and the frame 2 are respectively provided in two, and the frame 2 is provided at the top end of the base plate 1; a plurality of cross bars 3 are respectively installed at the top ends of the two base plates 1 and are located on the inner sides of the two frames 2, and a plurality of rectangular through grooves are provided on the plurality of cross bars 3; a plurality of longitudinal bars 4 respectively penetrate the plurality of rectangular through grooves; a fixing mechanism is provided on the plurality of longitudinal bars 4 and the cross bar 3; two base columns 5 are respectively arranged at the top ends of the plurality of cross bars 3, and the outer wall surfaces are connected to the fixing mechanism; two columns 6 are respectively arranged on the inner sides of the two base columns 5; the longitudinal vibration isolation mechanism is provided on the inner sides of the two base columns 5 and at the bottom ends of the columns 6; the transverse vibration isolation mechanism is installed at the top ends of the two columns 6; a cross beam 7, and the end of the cross beam 7 is connected to the transverse vibration isolation mechanism.

[0023] It should be noted that the two base plates 1 provide basic support for the entire device, and the frame 2 is arranged at the top of the base plate 1 to play a certain protective role. The rectangular through grooves opened by the several cross bars 3 are used for the several longitudinal bars 4 to pass through. By filling the frame 2 with concrete, the fixing mechanism is fixed to the base column 5 and the base plate 1, thereby building a stable underlying structure. The two base columns 5 are arranged at the top of the cross bars 3 and connected to the fixing mechanism to ensure the stability of the base column 5. The two columns 6 are located on the inner side of the base column 5, and the longitudinal vibration isolation mechanism is arranged on the inner side of the base column 5 and the bottom end of the column 6, which can play a vibration isolation and buffering role when subjected to longitudinal force. The transverse vibration isolation mechanism is installed at the top of the column 6, and the end of the cross beam 7 is connected to the transverse vibration isolation mechanism. When there is a transverse force, the transverse vibration isolation mechanism can effectively buffer and isolate the vibration. When the beam and column are connected, the device can buffer and isolate both longitudinal and transverse forces, thereby ensuring the stability and safety of the beam-column connection structure.

[0024] In some examples, the inner side of the frame 2 is filled with a concrete layer. The concrete layer can be tightly bonded to the frame 2, crossbars 3, and longitudinal bars 4. When the device is subjected to external forces, it acts as a whole to limit the relative displacement of the various components. In the event of a lateral force, it can prevent the crossbars 3 and longitudinal bars 4 from excessive deformation and displacement, thereby enhancing structural stability. Due to its high compressive strength, in beam-column connection applications, when vertical loads are transmitted, it can share the pressure, and work in conjunction with the base column 5, crossbar 3, etc. to improve the load-bearing capacity and avoid overload damage. The concrete layer provides a good fixing foundation for the fixing mechanism, using its own strength to help the fixing mechanism connect the base column 5 and the base plate 1. Under various directional forces, especially in vibration environments, the connection effect is guaranteed, loosening and disengagement are prevented, and the normal operation of the device is guaranteed. The concrete layer can also absorb and disperse vibration energy to a certain extent. Relying on the internal micro-particle structure and mass to reflect, scatter and absorb vibration waves, it cooperates with the longitudinal and lateral vibration isolation mechanisms to effectively reduce the vibration transmitted to other parts of the building structure and improve the overall vibration isolation performance.

[0025] In some examples, the fixing mechanism includes: an insertion rod 8, a nut 9, a stabilizing plate 10 and a leakage hole 11. The bottom ends of several insertion rods 8 are respectively inserted from the top of several cross bars 3 and pass through the bottom of the base plate 1; several nuts 9 are respectively screwed on the outer side of the outer wall of several insertion rods 8; two stabilizing plates 10 are respectively mounted on the outer side of the outer wall of several insertion rods 8 in the vertical direction, and a gap is formed between the two stabilizing plates 10 through the nut 9; several leakage holes 11 are respectively opened on the two stabilizing plates 10.

[0026] It should be noted that when working, the bottom ends of the plurality of insert rods 8 are first passed through the crossbar 3, longitudinal rod 4 and bottom plate 1 in sequence to achieve the positioning of the longitudinal rod 4, crossbar 3 and bottom plate 1. Then, the two stabilizing plates 10 are respectively fitted on the outer side of the outer wall of the insert rod 8 in the vertical direction, and then the nuts 9 are screwed onto the outer wall of the insert rod 8. The distance between the two stabilizing plates 10 is adjusted by tightening the nuts 9, and a specific gap is created between them. The leakage holes 11 on the stabilizing plates 10 facilitate the flow of materials or the exhaust of air during subsequent grouting operations, effectively fixing and positioning, ensuring the connection stability and reliability of the entire structure at this location, so as to adapt to the force requirements of the beam-column connection device under different working conditions and maintain the integrity of the overall structure.

[0027] In some examples, the longitudinal vibration isolation mechanism includes: a pressing member 12, a first spring 13, a connecting plate 14, a protrusion 15 and a second spring 16, and several pressing members 12 are respectively arranged at the bottom ends of the two columns 6; the bottom ends of several first springs 13 are respectively fixedly installed on the inner side of the base column 5; the bottom ends of the two connecting plates 14 are fixedly installed on the top ends of several first springs 13; several protrusions 15 are respectively fixedly installed on the top ends of the two connecting plates 14, and are movably connected to several pressing members 12, and grooves are opened on the inner sides of several protrusions 15; the bottom ends of several second springs 16 are respectively installed in several grooves and connected to several pressing members 12.

[0028] It should be noted that when the device is subjected to a longitudinal force, the several pressing members 12 located at the bottom of the column 6 are first subjected to the force and displaced. This displacement compresses the second spring 16 connected to the pressing member 12. The second spring 16 is located within the groove inside the protrusion 15. Its deformation can initially buffer some of the longitudinal force and store energy. At the same time, the movement of the pressing member 12 acts on the connecting plate 14 fixedly connected to the top of the first spring 13, causing the several first springs 13 to also deform. The bottom of the first spring 13 is fixed inside the base column 5. This deformation process further absorbs and disperses the longitudinal force. Through the coordinated operation of the second spring 16 and the first spring 13, the longitudinal force is gradually converted into the elastic potential energy of the spring, thereby effectively reducing the impact of the longitudinal force on the entire beam-column connection device and ensuring the stability of the device under longitudinal force. After the force disappears, the spring returns to its original state due to its own elasticity, returning the components to their initial relative positions or near their initial positions to prepare for the next longitudinal force.

[0029] In some examples, a circular boss 17 is installed at the bottom end of the connecting plate 14, and a bevel is provided at the middle portion of the circular boss 17;

[0030] The inner side of the base column 5 is also provided with a plurality of third springs 18, a plurality of tilting blocks 19, a mounting seat 20 and a plurality of guide rods 21. The mounting seat 20 is fixedly arranged on the inner side of the base column 5. The ends of the plurality of tilting blocks 19 are connected to the plurality of third springs 18. The plurality of tilting blocks 19 match the inclined surface of the circular boss 17. The ends of the plurality of guide rods 21 are fixedly connected to the outer side of the outer wall of the mounting seat 20, and the other ends are movably plugged into the plurality of tilting blocks 19.

[0031] It should be noted that when the device is subjected to longitudinal force, in the aforementioned longitudinal vibration isolation mechanism, as the connecting plate 14 moves, the circular boss 17 at its bottom also moves. The inclined surface in the middle portion of the circular boss 17 contacts and interacts with the tilting block 19. Since the ends of several tilting blocks 19 are connected to the third spring 18, and the tilting block 19 matches the inclined surface of the circular boss 17, during the movement of the circular boss 17, the tilting block 19 will displace along the inclined surface, thereby stretching the third spring 18, causing the third spring 18 to deform and store energy, further absorbing and buffering the longitudinal force. At the same time, the guide rod 21 guides and limits the movement of the tilting block 19, ensuring that the tilting block 19 can move stably in the predetermined direction when subjected to the circular boss 17. This allows the third spring 18 to more effectively participate in the buffering process of the longitudinal force, cooperating with the first spring 13 and the second spring 16 to enhance the buffering and vibration isolation performance of the entire longitudinal vibration isolation mechanism when responding to longitudinal force, and ensure the stability and reliability of the device in complex force environments.

[0032] In some examples, the lateral vibration isolation mechanism includes: a shell 22, a baffle 23, a cylinder 24, a fourth spring 25, a first elastic member 26 and a second elastic member 27. The two shells 22 are respectively fixed on the top ends of the two columns 6; the two baffles 23 are respectively fixed at the two ends of the beam 7, and are respectively movably arranged on the inner sides of the two shells 22; several cylinders 24 are respectively fixed on the inner sides of the two shells 22; several fourth springs 25 are respectively installed on the inner sides of the cylinders 24, and the top ends are fixedly connected to the baffle 23; several first elastic members 26 are respectively installed on one side of the baffle 23; and several second elastic members 27 are respectively installed on the inner side of the shell 22.

[0033] It should be noted that when the crossbeam 7 is subjected to a lateral force, the baffles 23 fixed at both ends thereof will move inside the housing 22 fixed to the top of the column 6. At this point, the fourth spring 25, mounted inside the cylinder 24 and fixedly connected to the baffle 23, begins to operate. Due to the displacement of the baffle 23, the fourth spring 25 is compressed or stretched, and its own elastic deformation initially cushions the lateral force, converting some of the energy into stored elastic potential energy. Simultaneously, the first elastic member 26 located on one side of the baffle 23 and the second elastic member 27 inside the housing 22 are also affected by the movement of the baffle 23 and deform. During the movement of the baffle 23, the first elastic member 26, based on its own elastic properties, shares and absorbs the lateral force with the fourth spring 25, thereby hindering and cushioning the movement of the baffle 23. The second elastic member 27 supports and further cushions the baffle 23, limiting its excessive displacement. Therefore, the present device can effectively disperse, absorb and transform the lateral force, thereby reducing the impact and influence of the lateral force on the beam-column connection structure, ensuring the stability and reliability of the entire device under lateral force conditions, and after the lateral force disappears, the fourth spring 25, the first elastic member 26 and the second elastic member 27 can return to their initial state by virtue of their own elasticity, so that the relevant components also return to their initial relative positions in order to cope with the next possible lateral force.

[0034] In some examples, the ends of the plurality of first elastic members 26 and the second elastic members 27 are all provided with matching inclined surfaces.

[0035] It should be noted that when the device encounters a lateral force, the baffles 23 at both ends of the crossbeam 7 are displaced inside the housing 22, causing the first elastic member 26 connected thereto and the second elastic member 27 inside the housing 22 to deform, thereby buffering the lateral force. During this process, since the ends of the first elastic member 26 and the second elastic member 27 are both provided with matching inclined surfaces, as the deformation of the two continues, the inclined surfaces of their ends gradually align with each other. The inclined surfaces are fitted together so that the first elastic member 26 and the second elastic member 27 can form a stable contact interface when in contact. When buffering lateral force, the force can be evenly distributed and transmitted along the inclined surfaces. According to their respective elastic characteristics, they can share the pressure and impact force brought by the lateral force, avoiding the occurrence of excessive or uneven local force, effectively improving the buffering effect and stability of the entire lateral vibration isolation mechanism against lateral force, and ensuring the normal operation of the beam-column connection device under lateral force conditions. After the lateral force disappears, the first elastic member 26 and the second elastic member 27 will return to their original state by their own elasticity, and their end inclined surfaces will also separate and return to their initial state to cope with possible subsequent lateral force effects.

[0036] In some examples, the size of the middle portion of the plurality of fourth springs 25 is larger than the size of the ends, and the middle portion fits in contact with the plurality of cylinders 24 .

[0037] It should be noted that when the device is subjected to lateral forces and the baffles 23 at both ends of the beam 7 are displaced, the fourth spring 25, fixedly connected to the baffles 23, begins to respond. Because the middle portion of the fourth spring 25 is larger than the ends and the middle portion fits closely with the cylinder 24, during the deformation process of the four springs under force, the larger middle portion of the spring 25 comes into close contact with the inner wall of the cylinder 24. This fit provides good lateral support and guidance for the fourth spring 25, allowing it to stably deform along the predetermined direction when compressed or stretched, preventing instabilities such as bending, twisting, or deflection during force application. This ensures that the fourth spring 25 can more effectively convert lateral forces into its own elastic potential energy for buffering. Furthermore, this stable deformation process helps extend the service life of the fourth spring 25, ensuring that it can reliably perform its buffering function under multiple force conditions. This, in turn, provides stable and effective buffering performance for the entire beam-column-connected vibration isolation device under lateral forces, maintaining the device's structural stability and reliability under lateral forces.
