Description

Technical Field

[0001] This invention belongs to the field of energy dissipation, vibration reduction and vibration control technology of civil engineering building structures, specifically relating to a rolling ring wedge close-fitting hinge node of a building structure energy dissipator and its assembly method. Background Technology

[0002] Energy dissipators in building structures are generally installed in the main structure in the form of diagonal or A-frame supports. Under earthquake / wind vibration, the relative horizontal displacement between floors of the building structure is directly (or amplified by a mechanical amplification device) converted into the relative linear displacement at both ends of the energy dissipator. This linear displacement induces deformation hysteresis in the energy dissipator, providing additional damping for the building structure.

[0003] The aforementioned structure involves the following node connections: the connection between the energy dissipator and the main structure, the connection between the energy dissipator and the mechanical amplification device, and the connection between the mechanical amplification device and the main structure. These connections typically employ a pin-type hinge structure. Traditional pin-type hinge connections have three main problems: First, due to limited machining and installation precision, the pin diameter is smaller than the hole diameter on each connecting plate. When the structure undergoes slight deformation, the gap between the pin and the plate allows for relative linear displacement, resulting in insufficient constraint on relative linear displacement. Second, because the contact between the pin and each component is a sliding contact, the starting torque for relative rotation of the hinge node is not zero, making the rotation between components insensitive. This results in insufficient release of relative angular displacement. In scenarios where zero starting torque is strictly required, the aforementioned sliding contact surfaces need to be lubricated to reduce the impact of sliding friction. This requirement involves daily maintenance issues and is not convenient to use. Third, this type of connection is generally designed and verified based on the deformation requirements of the elastic stage or the finite plastic stage of the structure. Although its rotational capacity can meet the requirements of such scenarios, traditional pin connections may not be able to guarantee that the nodes have sufficient rotational capacity for large displacement rotation requirements under large structural deformation and strong nonlinear scenarios.

[0004] Furthermore, current seismic design requirements for building structures are gradually transitioning from the original three-level seismic fortification goal (i.e., "no damage in minor earthquakes, repairable in moderate earthquakes, and no collapse in major earthquakes") to the higher four-level seismic fortification goal (i.e., "no damage in minor and moderate earthquakes, repairable or replaceable in major earthquakes, and no collapse in mega earthquakes"). The new seismic fortification requirements place higher demands on the deformation capacity of building structures, meaning that building structures will undergo greater plastic deformation. Traditional pin-type hinged connections, due to the three issues mentioned above, cannot meet these higher seismic fortification requirements.

[0005] To address the aforementioned issues, there is an urgent need to develop a novel pin-type hinge joint that can strictly constrain relative linear displacement, efficiently release rotational capacity (with a rotational starting torque approximately zero), and is applicable to rotational requirements under scenarios of large structural deformation. Summary of the Invention

[0015] Step S3: Pass the pin through the energy dissipator connecting plate and another obliquely cut hole node plate in sequence, and symmetrically insert rolling ring wedges between the pin and the wall of the circular hole of the connecting plate and the wall of the obliquely cut circular hole.

[0021] The role and effect of invention

[0022] According to the present invention, a rolling ring wedge close-fitting hinge node for a building structure energy dissipator and its assembly method thereof, the rolling ring wedge close-fitting hinge node for a building structure energy dissipator based on rolling contact can meet the rotational requirements generated by the building structure under large deformation and strong nonlinear scenarios. When the building structure deforms, the rolling ring wedge, which fills the gap between the pin shaft and the obliquely cut circular hole and the circular hole of the connecting plate, can constrain the relative linear displacement between the components, so that the deformation of the building structure (or after being amplified by a mechanical amplification device) can be completely converted into the deformation stroke of the energy dissipator.

[0023] Furthermore, in this invention, the rolling ring wedge uses ball rollers to make point contact with the pin shaft, ensuring that the rolling ring wedge and the pin shaft always maintain rolling contact. This greatly reduces the rotational lag caused by sliding friction in traditional pin-type hinge joints, significantly reduces the limitation of the hinge joint's rotational starting torque, and almost achieves the requirement of zero starting torque for an ideal hinge joint. This further improves the hinge joint's rotational capability, meets the large rotation angle requirements of the joint in nonlinear large displacement scenarios of building structures, and enables a fast and efficient response to various vibrations.

[0024] Meanwhile, the design of the rolling ring wedge reduces the pressure on daily maintenance of the nodes, eliminates the need for repeated lubrication, and improves the ease of assembly.

[0025] Therefore, the rolling ring wedge close-fitting hinge node of the building structure energy dissipator of the present invention can achieve high performance requirements such as constraining relative linear displacement, releasing relative angular displacement, zero rotational starting torque, and ultra-large rotation. It can be assembled at the ends of building structure energy dissipators, mechanical stroke amplification devices, and structural components, and can maximize the release of rotational flexibility and control of relative linear displacement, ensuring that the building structure energy dissipator responds quickly and efficiently to various vibrations.

[0039] like Figure 2 As shown, the obliquely cut hole node plate 10 includes a plate body 11 and an obliquely cut circular hole 12 disposed on the plate body 11.

[0040] In this embodiment, the plate 11 is a common steel structure plate with a through obliquely cut circular hole 12 in the middle. The inner wall of the obliquely cut circular hole 12 is an inclined surface and matches the side wall shape of the guide groove ring wedge 41.

[0041] Figure 3 This is a schematic diagram of the structure of the energy dissipation connecting plate and energy dissipator in an embodiment of the present invention.

[0042] like Figure 3 As shown, the energy dissipation connecting plate 20 is used to connect the energy dissipator 21 and is set between two obliquely cut node plates 10, and has a connecting plate circular hole 22.

[0043] In this embodiment, the energy dissipation connecting plate 20 is a common steel structure plate with a through-hole 22 in the middle. The inner walls on both sides of the connecting plate hole 22 are inclined surfaces, which match the side wall shape of the guide groove ring wedge 41. The energy dissipator 21 is a building structure energy dissipator, which introduces additional damping into the building structure.

[0044] Figure 4 This is a schematic diagram of the pin structure in an embodiment of the present invention.

[0045] like Figure 4 As shown, the pin 30 passes through the oblique cut circular hole 12 and the connecting plate circular hole 22, and is used to connect the oblique cut node plate 10 and the energy dissipation connecting plate 20 in series.

[0046] In this embodiment, the pin 30 is a steel cylinder with pre-engraved standard threads at both ends.

[0047] Figure 5 This is an exploded view of the structure of the rolling ring wedge in an embodiment of the present invention.

[0048] like Figure 5 As shown, the rolling ring wedge 40 includes a guide groove ring wedge 41 inserted between the obliquely cut circular hole 12, the connecting plate circular hole 22 and the pin 30, and a wedge head 42 integrally formed with the guide groove ring wedge 41 and fitted to the outside of the obliquely cut circular hole 12 and the connecting plate circular hole 22.

[0049] Furthermore, both the obliquely slit circular hole 12 and the connecting plate circular hole 22 have a central hole in their center. The inner walls on both sides of the central hole are gently sloping surfaces that diffuse outward from the central hole. After the pin 30 passes through the central hole, there is a gap between it and the inner walls on both sides of the obliquely slit circular hole 12 and the connecting plate circular hole 22. A rolling ring wedge 40 is symmetrically provided on both sides of the obliquely slit circular hole 12 and the connecting plate circular hole 22. The inner walls on both sides of the obliquely slit circular hole 12 and the connecting plate circular hole 22 are matched with the side wall shape of the guide groove ring wedge 41. The guide groove ring wedge 41 is inserted into the gap between the obliquely slit circular hole 12, the connecting plate circular hole 22 and the pin 30, and the wedge head 42 is fitted to the outside of the obliquely slit circular hole 12 and the connecting plate circular hole 22.

[0050] The guide ring wedge 41 is provided with a large-diameter annular guide groove 411 and a small-diameter annular guide groove 412. The large-diameter annular guide groove 411 is provided with a rotatable large-diameter ball roller-cage assembly, and the small-diameter annular guide groove 412 is provided with a rotatable small-diameter ball roller-cage assembly. The large-diameter ball roller-cage assembly and the small-diameter ball roller-cage assembly rotate freely in the large-diameter annular guide groove 411 and the small-diameter annular guide groove 412, and maintain rolling contact with the pin 30 through point contact.

[0051] The large-diameter ball roller-cage assembly includes a large cage 413 disposed in a large-diameter annular guide groove 411. The large cage 413 is uniformly surrounded by a plurality of through-holes, and each of the large holes is provided with a rollable large-diameter ball roller 414, which is a steel ball.

[0052] The small diameter ball roller-cage assembly includes a small cage 415 disposed in a small diameter annular guide groove 412. The small cage 415 is evenly arranged with a plurality of through holes, and each of the small holes is provided with a rollable small diameter ball roller 416, which is a steel ball.

[0053] In this embodiment, the ball bearings are matched and engaged within the corresponding pockets, and can rotate within the corresponding pockets.

[0054] The large-diameter annular guide groove 411 is also provided with a large-diameter sliding groove that matches the large-diameter ball roller 414. One side of the large-diameter ball roller 414 is placed in the large-diameter sliding groove, and the other side maintains rolling contact with the pin 30 through point contact. The large-diameter ball roller-cage assembly can rotate 360° without obstruction in the large-diameter annular guide groove 411 through the cooperation of the large-diameter ball roller 414 and the large-diameter sliding groove.

[0055] The small-diameter annular guide groove 412 is also provided with a small-diameter sliding groove that matches the small-diameter ball roller 416. One side of the small-diameter ball roller 416 is placed in the small-diameter sliding groove, and the other side maintains rolling contact with the pin 30 through point contact. The small-diameter ball roller-cage assembly can rotate 360° without obstruction in the small-diameter annular guide groove 412 through the cooperation of the small-diameter ball roller 416 and the small-diameter sliding groove.

[0056] Figure 6 This is a cross-sectional view of the rolling ring wedge in an embodiment of the present invention.

[0057] like Figure 6 As shown, the cross-section of the rolling ring wedge 40 is a grooved woodpecker beak shape. The cross-section of the woodpecker beak shape includes two parts: the beak and the head. The beak is a slender triangular cone shape that gradually thickens from the head to the tail. The head is trapezoidal and smoothly transitions to the tail of the beak.

[0058] Furthermore, such as Figure 6 As shown, both the large-diameter annular guide groove 411 and the small-diameter annular guide groove 412 are annular guide rails, used to accommodate the large-diameter ball roller-cage assembly and the small-diameter ball roller-cage assembly, respectively. The large-diameter annular guide groove 411 and the small-diameter annular guide groove 412 have the same structure. Taking the large-diameter annular guide groove 411 as an example, a large-diameter sliding groove corresponding to and matching the large-diameter ball roller 414 is recessed in the center of the large-diameter annular guide groove 411. The large-diameter ball roller 413, which is circular in shape, is correspondingly arranged in the large-diameter annular guide groove 411. One end of the large-diameter ball roller 414, which is rotatably installed in the large pocket, is placed in the large-diameter sliding groove, which can limit the axial displacement of the large-diameter ball roller 414. The large-diameter ball roller-cage assembly can rotate 360° without obstruction in the large-diameter annular guide groove 411 through the cooperation of the large-diameter ball roller 414 and the large-diameter sliding groove. At the same time, the other end of the large-diameter ball roller 414 maintains rolling contact with the pin 30 through point contact.

[0059] Figure 7 This is a schematic diagram of the nut-washer assembly in an embodiment of the present invention.

[0060] like Figure 7 As shown, nut-washer assemblies 50 are also fitted on both sides of the pin 30, and the nut-washer assemblies 50 are located on the outside of the obliquely cut hole node plate 10. Each nut-washer assembly 50 includes a nut 51, a large-diameter washer 52 that is tightly fitted to the nut 51, and a small-diameter washer 53 that is tightly fitted to both the large-diameter washer 52 and the wedge head 42. The reliability of the fastening force transmission is enhanced by the joint operation of the large-diameter washer 52 and the small-diameter washer 53.

[0061] In this embodiment, the nut 51 is a hexagonal nut with a standard hexagonal threaded hole inside, and the external threads at both ends of the pin 30 match the internal threads inside the nut 51.

[0062] The conversion and transfer plate 60 is fixedly connected to the oblique section hole node plate 30 and is used to connect external components, such as building structure energy dissipators, mechanical stroke amplification devices and structural components.

[0063] In this embodiment, the conversion and transfer plate 60 is a common steel structure node plate with several round holes to facilitate connection with beams, columns and other components in the building structure.

[0064] Figure 8 This is a schematic diagram of the assembly process of the rolling ring wedge close-fitting hinge node of the building structure energy dissipator in an embodiment of the present invention.

[0065] like Figure 8As shown, the assembly method of the rolling ring wedge close-fitting hinge node 100 of the building structure energy dissipator in this embodiment includes the following steps:

[0066] Step S1: Pre-assemble to obtain the rolling ring wedge 40.

[0067] Step S1 includes the following sub-steps:

[0068] Step S1-1: The large-diameter ball roller 414 and the small-diameter ball roller 416 are pre-installed into the large pocket and the small pocket respectively, and the large-diameter ball roller 414 and the small-diameter ball roller 416 are checked one by one to see if they can roll without obstruction in the large pocket and the small pocket respectively. The large-diameter ball roller-cage assembly and the small-diameter ball roller-cage assembly are obtained by corresponding assembly.

[0069] In steps S1-2, the large-diameter ball roller-cage assembly and the small-diameter ball roller-cage assembly are respectively installed into the large-diameter annular guide groove 411 and the small-diameter annular guide groove 412, and the large-diameter ball roller-cage assembly and the small-diameter ball roller-cage assembly are checked one by one to see if they can rotate without obstruction in the large-diameter annular guide groove 411 and the small-diameter annular guide groove 412, and the rolling ring wedge 40 is obtained by corresponding assembly.

[0070] Step S2: Pass the pin 30 through the obliquely cut circular hole 12 of the obliquely cut node plate 10, and symmetrically insert the rolling ring wedge 40 between the pin 30 and the hole wall of the obliquely cut circular hole 12.

[0071] In step S3, the pin 30 is passed sequentially through the energy dissipator connecting plate 20 and another obliquely cut node plate 10. Before the pin 30 is passed through, a rolling ring wedge 40 is fitted on each of them. After passing through, the rolling ring wedge 40 is symmetrically inserted between the pin 30 and the wall of the connecting plate circular hole 22 and the wall of the obliquely cut circular hole 12.

[0072] Step S4: Install nut-washer assembly 50 on the outside of the two obliquely cut node plates 10 and tighten nut 51 to make the pin 30, rolling ring wedge 40, energy dissipator connecting plate 20 and obliquely cut node plate 10 tightly wedge together.

[0073] Step S5: After welding the two obliquely cut node plates 10 to the conversion and transmission plate 60 as a whole, the assembly of the rolling ring wedge tight-fitting hinge node 100 of the building structure energy dissipator is completed. Furthermore, the energy dissipator connecting plate 20 is connected to the building structure energy dissipator, and the conversion and transmission plate 60 is connected to the building structure energy dissipator, mechanical stroke amplification device, and structural components. The rolling ring wedge tight-fitting hinge node 100 of the building structure energy dissipator ensures a rapid and efficient response of the building structure energy dissipator to various vibrations.

[0074] The role and effect of the embodiments

[0075] According to the rolling ring wedge close-fitting hinge node and its assembly method for a building structure energy dissipator involved in this embodiment, the rolling ring wedge close-fitting hinge node of the building structure energy dissipator based on rolling contact in this embodiment can meet the rotation requirements generated by the building structure under large deformation and strong nonlinear scenarios. When the building structure deforms, the rolling ring wedge, which fills the gap between the pin shaft and the oblique section circular hole and the circular hole of the connecting plate, can constrain the relative linear displacement between the components, so that the deformation of the building structure (or after being amplified by a mechanical amplification device) can be completely converted into the deformation stroke of the energy dissipator.

[0076] Furthermore, in this embodiment, the rolling ring wedge uses ball rollers to make point contact with the pin, ensuring that the rolling ring wedge and the pin always maintain rolling contact. This greatly reduces the rotational lag caused by sliding friction in traditional pin-type hinge joints, significantly reduces the limitation of the hinge joint's rotational starting torque, and almost achieves the requirement of zero starting torque for an ideal hinge joint. This further improves the hinge joint's rotational capability, meets the large rotation angle requirements of the joint in nonlinear large displacement scenarios of building structures, and enables a fast and efficient response to various vibrations.

[0077] Meanwhile, the design of the rolling ring wedge reduces the pressure on daily maintenance of the nodes, eliminates the need for repeated lubrication, and improves the ease of assembly.

[0078] Therefore, the rolling ring wedge close-fitting hinge node of the building structure energy dissipator in this embodiment can achieve high performance requirements such as constraining relative linear displacement, releasing relative angular displacement, zero rotational starting torque, and ultra-large rotation. It can be assembled at the ends of building structure energy dissipators, mechanical stroke amplification devices, and structural components, and can maximize the release of rotational flexibility and control of relative linear displacement, ensuring that the building structure energy dissipator responds quickly and efficiently to various vibrations.
