Description

Technical Field

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

[0002] Urban rail transit is a large-capacity public transportation infrastructure and a backbone transportation mode for cities to guide low-carbon travel. At present, my country's urban rail transit is still in a rapid development stage and continues to maintain a growth trend. The development of prefabricated subway station structure technology can shorten the construction period, realize the full, efficient and intensive use of land resources, improve social and economic benefits and the quality of life of residents, and is conducive to the sustainable development of the city. In actual projects, the design of prefabricated subway stations should take into account the impact of earthquakes to ensure the safety of subway stations and superstructures under earthquakes. At the same time, the vibration generated by the operation of subway trains will be transmitted to the upper buildings through the subway stations, causing vibrations in the upper buildings and generating secondary noise, which has a great impact on the work and life of people in the upper buildings. Therefore, it is necessary to take vibration isolation (seismic) measures to meet the safety and comfort of the buildings above the subway.

[0003] The traditional subway station beam-column connection structure is usually relatively simple and direct, and mostly adopts a rigid connection method, that is, the beam is directly fixed to the column by 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 train operation, the beam-column connection will directly bear huge impact and vibration forces, which can easily lead to stress concentration, causing cracks, deformations, 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 the vibration to spread in the structure, affecting people's comfort and the normal operation of precision instruments and equipment.

[0018] See also Figure 1-Figure 5 A buffer vibration isolation device for connecting beams and columns of an assembled subway station provided in an embodiment of the present application comprises: a bottom 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 bottom plate 1 and the frame 2 are respectively provided in two, and the frame 2 is provided at the top of the bottom plate 1; a plurality of cross bars 3 are respectively installed at the tops of the two bottom 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 a plurality of longitudinal bars 4 and the cross bars 3; two base columns 5 are respectively arranged at the tops 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 arranged 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 tops 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.

[0019] 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 plurality of cross bars 3 are passed through by the plurality of longitudinal bars 4. By filling the frame 2 with concrete, the fixing mechanism is fixed to the base column 5 and the base plate 1, thereby constructing 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 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.

[0020] In some examples, the inner side of the frame 2 is filled with a concrete layer. The concrete layer can be tightly combined with the frame 2, the crossbar 3, and the longitudinal bar 4. When the device is subjected to external force, it can limit the relative displacement of each component as a whole. In case of lateral force, it can prevent the crossbar 3 and the longitudinal bar 4 from excessive deformation and displacement, thereby enhancing the structural stability. With its own high compressive strength, in the application of beam-column connection, when the vertical load is transmitted, it can share the pressure, and cooperate with the base column 5, the crossbar 3, etc. to improve the bearing capacity and avoid overload damage. Its existence provides a good fixing foundation for the fixing mechanism, and uses its own firmness to help the fixing mechanism connect the base column 5 and the base plate 1. Under various directional forces, especially in vibration environments, it ensures the connection effect, prevents loosening and separation, and ensures the normal operation of the device. It 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, and cooperate 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.

[0021] 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 nuts 9; and several leakage holes 11 are respectively opened on the two stabilizing plates 10.

[0022] It should be noted that, when working, firstly, the bottom ends of several plug rods 8 are passed through the cross bar 3, the longitudinal bar 4 and the bottom plate 1 in sequence to realize the positioning of the longitudinal bar 4, the cross bar 3 and the bottom plate 1. Then, the two stabilizing plates 10 are respectively mounted on the outer side of the outer wall of the plug rod 8 in the vertical direction, and then the nut 9 is screwed on the outer wall of the plug rod 8. The distance between the two stabilizing plates 10 is adjusted by tightening the nut 9, and a specific gap is formed between the two. The leakage holes 11 on the stabilizing plates 10 facilitate the flow of materials or the discharge of air in subsequent grouting operations, etc., effectively fix and position, ensure the connection stability and reliability of the entire structure at this part, 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.

[0023] In some examples, the longitudinal vibration isolation mechanism includes: a pressing piece 12, a first spring 13, a connecting plate 14, a protrusion 15 and a second spring 16, wherein a plurality of pressing pieces 12 are respectively arranged at the bottom ends of the two columns 6; the bottom ends of a plurality of first springs 13 are respectively fixedly mounted on the inner sides of the base columns 5; the bottom ends of the two connecting plates 14 are fixedly mounted on the top ends of a plurality of first springs 13; a plurality of protrusions 15 are respectively fixedly mounted on the top ends of the two connecting plates 14, and are movably connected to a plurality of pressing pieces 12, and grooves are provided on the inner sides of a plurality of protrusions 15; the bottom ends of a plurality of second springs 16 are respectively mounted in a plurality of grooves, and are connected to a plurality of pressing pieces 12.

[0024] It should be noted that when the device is subjected to longitudinal force, the plurality of pressing members 12 located at the bottom of the column 6 are first subjected to force and displaced. This displacement will cause the second spring 16 connected to the pressing member 12 to be compressed. The second spring 16 is located in the inner groove of the protrusion 15, and its deformation can initially buffer a part of the longitudinal force and store energy. At the same time, the movement of the pressing member 12 will act on the connecting plate 14 fixedly connected to the top of the first spring 13, causing the plurality of first springs 13 to also deform. The bottom of the first spring 13 is fixed to the inner side of the base column 5, and its deformation process further absorbs and disperses the longitudinal force. Through the coordinated work 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, ensuring the stability of the device under longitudinal force, and after the force disappears, the spring relies on its own elasticity to restore the original state, so that each component returns to the initial relative position or close to the initial position, so as to cope with the next longitudinal force situation.

[0025] 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; 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 surfaces of the circular bosses 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 with the plurality of tilting blocks 19.

[0026] It should be noted that when the device is subjected to longitudinal force, in the above-mentioned longitudinal vibration isolation mechanism, as the connecting plate 14 moves, the circular boss 17 at its bottom also moves together. The inclined surface in the middle part of the circular boss 17 contacts and interacts with the inclined block 19. Since the ends of several inclined blocks 19 are connected to the third spring 18, and the inclined block 19 matches the inclined surface of the circular boss 17, during the movement of the circular boss 17, the inclined block 19 will be displaced 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 inclined block 19, ensuring that the inclined block 19 can move stably along the predetermined direction when it is acted upon by the circular boss 17, so that the third spring 18 can more effectively participate in the buffering process of the longitudinal force, cooperate with the first spring 13 and the second spring 16, enhance the buffering and vibration isolation performance of the entire longitudinal vibration isolation mechanism when dealing with longitudinal force, and ensure the stability and reliability of the device under complex force environments.

[0027] 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 fixedly arranged at the top ends of the two columns 6; the two baffles 23 are respectively fixedly arranged at the two ends of the beam 7, and are respectively movably arranged on the inner sides of the two shells 22; a number of cylinders 24 are respectively fixedly arranged on the inner sides of the two shells 22; a number of fourth springs 25 are respectively installed on the inner sides of the cylinders 24, and the top ends are fixedly connected to the baffles 23; a number of first elastic members 26 are respectively installed on one side of the baffle 23; a number of second elastic members 27 are respectively installed on the inner side of the shell 22.

[0028] It should be noted that when the cross beam 7 is subjected to a lateral force, the baffles 23 fixed at both ends thereof will move inside the shell 22 fixed to the top of the column 6. At this time, the fourth spring 25 installed on the inner side of 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 relies on its own elastic deformation to initially buffer the lateral force, converting part of the energy into elastic potential energy for storage. At the same time, the first elastic member 26 located on one side of the baffle 23 and the second elastic member 27 on the inner side of the shell 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 characteristics, shares and absorbs the lateral force together with the fourth spring 25, thereby hindering and buffering the movement of the baffle 23. The second elastic member 27 supports and further buffers the baffle 23, limiting the excessive displacement of the baffle 23. Therefore, the 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 restore 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.

[0029] 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.

[0030] 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 shell 22, driving the first elastic member 26 connected thereto and the second elastic member 27 inside the shell 22 to deform to buffer the lateral force. In 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 develops, the inclined surfaces of their ends gradually fit each other. The inclined surfaces are fitted so that the first elastic member 26 and the second elastic member 27 can form a stable contact interface when in contact. When buffering the lateral force, the force can be evenly distributed and transmitted along the inclined surface. According to their respective elastic characteristics, they can share the pressure and impact force brought by the lateral force, thereby avoiding the situation where local force is excessive or uneven, and effectively improving the buffering effect and stability of the entire lateral vibration isolation mechanism against the lateral force, thereby ensuring the normal operation of the beam-column connection device under the lateral force condition. 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 the initial state to cope with possible subsequent lateral force effects.

[0031] In some examples, the size of the middle portion of the plurality of fourth springs 25 is larger than the size of the two ends, and the middle portion and the plurality of cylinders 24 fit each other.

[0032] It should be noted that when the device is subjected to a lateral force and the baffles 23 at both ends of the beam 7 are displaced, the fourth spring 25 fixedly connected to the baffle 23 begins to respond. Since the size of the middle part of the fourth spring 25 is larger than the size of the two ends and the middle part fits with the cylinder 24, during the deformation process of the four springs under force, the middle part of the larger size is in close contact with the inner wall of the cylinder 24. The fitting relationship provides good lateral support and guiding effect for the fourth spring 25, so that the fourth spring 25 can be stably deformed along a predetermined direction when compressed or stretched, avoiding the fourth spring 25 from bending, twisting or deflecting during the force process, thereby ensuring that the fourth spring 25 can more effectively convert the lateral force into its own elastic potential energy for buffering. At the same time, the stable deformation process is also conducive to extending the service life of the fourth spring 25, ensuring that it can still reliably play a buffering role under multiple force conditions, and then continuously providing a stable and effective buffering performance for the entire beam-column connected buffering and vibration isolation device when subjected to lateral force, and maintaining the structural stability and reliability of the device under the action of lateral force.
