Description

Technical Field

[0001] The invention relates to the technical field of seismic isolation, in particular to an ultra-high damping elastic skateboard support. Background Art

[0002] Base isolation technology is one of the mature high-tech technologies that is currently being promoted and applied more widely in the world's earthquake engineering community. The so-called base isolation technology is to set up a soft isolation layer composed of isolation devices between the superstructure of the building and the foundation. When an earthquake occurs, almost all of the seismic energy is absorbed by the isolation layer, thereby preventing the superstructure from being damaged.

[0003] Currently, the most widely used seismic isolation bearings are mainly divided into two categories according to their different performances: rubber seismic isolation bearings and elastic skateboard bearings. Although the elastic skateboard bearings can dissipate part of the seismic energy through the relative sliding of the friction pair when an earthquake occurs, their energy dissipation efficiency is relatively low and they are unable to completely absorb and dissipate all seismic energy. This will cause part of the energy to still be transmitted to the superstructure, causing certain damage to the building. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that, when an earthquake occurs, although the elastic slide plate bearing can dissipate part of the seismic energy through the relative sliding of the friction pair, its energy dissipation efficiency is relatively low and it is unable to completely absorb and dissipate all seismic energy, which will cause part of the energy to still be transmitted to the superstructure, causing certain damage to the building, thereby providing an ultra-high damping elastic slide plate bearing.

[0005] In order to solve the above technical problems, the present invention provides an ultra-high damping elastic skateboard support, comprising a flange plate, a damping member is connected to the bottom of the flange plate, a frame is connected to the inside of the damping member, a sealing plate is connected to the bottom of the damping member, and a polytetrafluoroethylene plate is connected to the bottom of the sealing plate;

[0006] A plurality of fastening components are embedded in the sealing plate at equal intervals in a circle, a plurality of locking components are movably inserted in the polytetrafluoroethylene plate at equal intervals in a circle, and the locking components are inserted in the interior of the fastening components.

[0007] Furthermore, the flange plate comprises a plate body, a bottom of the plate body is fixedly connected to a limiting block, and an outer surface of the limiting block is fixedly connected to a first locking ring.

[0008] Furthermore, a limiting groove is provided on the top of the damping member, and the limiting block is inserted into the limiting groove;

[0009] A locking groove is provided on the inner wall of the limiting groove, and the first locking ring is located inside the locking groove.

[0010] Furthermore, a process hole is provided in the middle of the damping member and the sealing plate, and a first plug rod is fixedly connected to the bottom of the limit block, and the first plug rod is movably inserted into the inside of the process hole.

[0011] Furthermore, the fastening assembly comprises a fastening sleeve, the fastening sleeve is embedded in the sealing plate, and a plug hole is provided in the middle of the fastening sleeve.

[0012] Furthermore, both sides of the interior of the fastening sleeve are provided with fixing grooves, and the fixing grooves are communicated with the insertion hole;

[0013] A telescopic rod is fixedly connected inside the fixing groove along the length direction, a thrust spring is sleeved on the outer surface of the telescopic rod, and a trapezoidal block is fixedly connected to one end of the telescopic rod.

[0014] Furthermore, the other end of the telescopic rod extends to the outside of the fastening sleeve, and the fixing sleeve at the other end of the telescopic rod is provided with a second locking ring.

[0015] Furthermore, one end of the thrust spring abuts against the inner wall of the trapezoidal block, and the other end of the thrust spring abuts against the inner wall of the fixing groove.

[0016] Furthermore, a groove is provided at the bottom of the sealing plate, and the top of the polytetrafluoroethylene plate is located inside the groove.

[0017] Furthermore, the locking assembly includes a bottom plate, a second plug rod is fixedly connected to the top of the bottom plate, and the second plug rod is movably plugged into the inside of the socket;

[0018] A conical block is fixedly sleeved on the outer surface of the second insertion rod, the outer diameter of the conical block increases from top to bottom, and the top of the trapezoidal block abuts against the bottom of the conical block.

[0019] Furthermore, the bottom of the polytetrafluoroethylene plate is connected to a sliding panel, and the bottom of the sliding panel is connected to a connecting plate.

[0020] By means of the above technical solution, the present invention provides an ultra-high damping elastic skateboard support, which has at least the following beneficial effects:

[0021] 1. The horizontal friction coefficient of the polytetrafluoroethylene plate of the ultra-high damping elastic skateboard bearing is ≤0.4, so that the skateboard bearing can effectively isolate most of the seismic energy when an earthquake occurs and reduce the direct impact of seismic waves on the upper structure. The loss-damping ratio of the damping element used is ≥0.2, so that the skateboard bearing can absorb and consume a large amount of seismic energy during an earthquake, significantly reduce the seismic force on the structure, and protect the building from damage.

[0022] 2. The ultra-high damping elastic skateboard support, the fastening assembly embedded in the sealing plate and the locking assembly in the polytetrafluoroethylene plate are plugged into each other, which not only enhances the overall stability of the skateboard support, but also ensures the reliability of the skateboard support during earthquakes, and prevents the reduction of seismic isolation effect due to structural loosening or failure.

[0023] 3. The first locking ring of the ultra-high damping elastic slide support is located inside the locking groove, which enhances the firmness of the connection, making the connection between the flange plate and the damping element more reliable and not easy to loosen or fall off. The design of the limit block and the first locking ring helps to disperse the stress at the connection. When subjected to external force, it can effectively disperse the stress to the entire connection area, reduce local stress concentration, and thus improve the strength and durability of the overall structure.

[0024] 4. The ultra-high damping elastic slide plate support has a first plug rod that is movably inserted into the process hole, ensuring that the relative positions of the damping member, the sealing plate and the flange plate are accurate and correct, thereby preventing loosening or failure of the connection caused by misalignment or offset of components during installation or use.

[0025] 5. The ultra-high damping elastic slide plate support, when the second plug rod of the locking assembly is inserted into the insertion hole, the conical block moves upward and pushes the trapezoidal block to move into the fixed groove, compressing the thrust spring. When the conical block moves to the top of the trapezoidal block, the thrust spring releases energy and pushes the trapezoidal block out of the fixed groove. At this time, the top of the trapezoidal block abuts against the bottom of the conical block, and the side of the trapezoidal block away from the telescopic rod abuts against the outer surface of the second plug rod. The cooperation between the trapezoidal block and the conical block realizes a tightening effect, preventing the polytetrafluoroethylene plate from loosening or falling off due to time or earthquake, and preventing the reduction of seismic isolation effect due to loosening or failure of the polytetrafluoroethylene plate.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figure 1 and Figure 4 As shown, an ultra-high damping elastic skateboard bearing comprises a flange plate 1, a damping member 2 is connected to the bottom of the flange plate 1, the loss-damping ratio of the damping member 2 is ≥0.2, a skeleton 3 is connected to the inside of the damping member 2, a sealing plate 4 is connected to the bottom of the damping member 2, a polytetrafluoroethylene plate 5 is connected to the bottom of the sealing plate 4, the horizontal friction coefficient of the polytetrafluoroethylene plate 5 is ≤0.4, and the horizontal friction coefficient of the polytetrafluoroethylene plate 5 is ≤0.4, so that the skateboard bearing can effectively isolate most of the seismic energy when an earthquake occurs, and reduce the direct impact of seismic waves on the upper structure. The loss-damping ratio of the damping member 2 used is ≥0.2, so that the skateboard bearing can absorb and consume a large amount of seismic energy during an earthquake, significantly reduce the seismic force on the structure, and protect the building from damage.

[0038] like Figure 1and Figure 4 As shown, a plurality of fastening assemblies 6 are embedded in the sealing plate 4 at equidistant intervals around the circumference, a plurality of locking assemblies 7 are movably inserted in the polytetrafluoroethylene plate 5 at equidistant intervals around the circumference, the locking assemblies 7 are inserted in the fastening assemblies 6, and the fastening assemblies 6 embedded in the sealing plate 4 and the locking assemblies 7 in the polytetrafluoroethylene plate 5 are inserted in each other, which not only enhances the overall stability of the skateboard support, but also ensures the reliability of the skateboard support during earthquakes, and prevents the reduction of seismic isolation effect due to structural loosening or failure.

[0039] In the present invention, Figure 2 and Figure 3 As shown, the flange plate 1 includes a plate body 101, a limiting block 102 is fixedly connected to the bottom of the plate body 101, and a first locking ring 103 is fixedly connected to the outer surface of the limiting block 102. A limiting groove 201 is provided on the top of the damping member 2, and the limiting block 102 is inserted into the inside of the limiting groove 201, which ensures that the relative position between the flange plate 1 and the damping member 2 is accurate and correct, and can prevent offset or dislocation during the connection process, thereby ensuring the accuracy and stability of the connection; a locking groove 202 is provided on the inner wall of the limiting groove 201, and the first locking ring 103 is located inside the locking groove 202, which enhances the firmness of the connection, making the connection between the flange plate 1 and the damping member 2 more reliable and not easy to loosen or fall off. The design of the limiting block 102 and the first locking ring 103 helps to disperse stress at the connection. When subjected to external force, the stress can be effectively dispersed to the entire connection area, reducing local stress concentration, thereby improving the strength and durability of the overall structure.

[0040] In the present invention, Figure 1 and Figure 4 As shown, a process hole 8 is provided in the middle of the damping member 2 and the sealing plate 4, and a first plug rod 104 is fixedly connected to the bottom of the limit block 102. The first plug rod 104 is movably inserted into the inside of the process hole 8, ensuring that the relative positions of the damping member 2, the sealing plate 4 and the flange plate 1 are accurate and correct, and preventing loose connection or failure due to misalignment or offset of components during installation or use.

[0041] In the present invention, Figure 4 , Figure 6 and Figure 7As shown, the fastening assembly 6 includes a fastening sleeve 601, which is embedded in the sealing plate 4, and a plug hole 602 is provided in the middle of the fastening sleeve 601. Both sides of the inside of the fastening sleeve 601 are provided with fixed grooves 603, and the fixed grooves 603 are connected with the plug hole 602; the inside of the fixed groove 603 is fixedly connected with a telescopic rod 604 along the length direction, and the outer surface of the telescopic rod 604 is sleeved with a thrust spring 606, and one end of the telescopic rod 604 is fixedly connected with a trapezoidal block 605. The other end of the telescopic rod 604 extends to the outside of the fastening sleeve 601, and the other end of the telescopic rod 604 is fixedly sleeved with a second locking ring 607. One end of the thrust spring 606 abuts against the inner side wall of the trapezoidal block 605, and the other end of the thrust spring 606 abuts against the inner wall of the fixing groove 603.

[0042] In the present invention, Figure 5 and Figure 8 As shown, countersunk holes are equidistantly arranged on the polytetrafluoroethylene plate 5 in a circle, and the locking assembly 7 is inserted into the countersunk holes. The locking assembly 7 includes a base plate 701, and the base plate 701 is located in the countersunk hole. A second plug rod 702 is fixedly connected to the top of the base plate 701, and the second plug rod 702 is movably inserted into the inside of the insertion hole 602; a conical block 703 is fixedly sleeved on the outer surface of the second plug rod 702, and the outer diameter of the conical block 703 increases from top to bottom, and the top of the trapezoidal block 605 abuts against the bottom of the conical block 703. When the second plug rod 702 of the locking assembly 7 is inserted into the socket 602, the conical block 703 moves upward and pushes the trapezoidal block 605 to move into the fixed groove 603, compressing the thrust spring 606. When the conical block 703 moves to the top of the trapezoidal block 605, the thrust spring 606 releases energy to push the trapezoidal block 605 out of the fixed groove 603. At this time, the top of the trapezoidal block 605 abuts against the bottom of the conical block 703, and the side of the trapezoidal block 605 away from the telescopic rod 604 abuts against the outer surface of the second plug rod 702. The cooperation between the trapezoidal block 605 and the conical block 703 realizes a tightening effect, preventing the polytetrafluoroethylene plate 5 from loosening or falling off due to time or earthquake, and preventing the reduction of the seismic isolation effect due to the loosening or failure of the polytetrafluoroethylene plate 5.

[0043] In the present invention, Figure 1 and Figure 4 As shown, the bottom of the sealing plate 4 is provided with a groove 401, and the top of the polytetrafluoroethylene plate 5 is located inside the groove 401. The groove 401 provides a positioning space for the polytetrafluoroethylene plate 5, ensuring that the polytetrafluoroethylene plate 5 can be accurately placed in the predetermined position during installation, avoiding misalignment or deviation during the installation process.

[0044] In the present invention, Figure 1As shown, the bottom of the polytetrafluoroethylene plate 5 is connected to a sliding panel 9, and the bottom of the sliding panel 9 is connected to a connecting plate 10. The polytetrafluoroethylene plate 5 can maintain good sliding performance when subjected to external force because of its horizontal friction coefficient ≤ 0.4. This sliding performance can slide on the sliding panel 9 when natural disasters such as earthquakes occur, thereby reducing the transmission of seismic force caused by the rigid connection of the structure and achieving a shock-absorbing effect.

[0045] Working principle: Place the top of the polytetrafluoroethylene plate 5 into the groove 401 at the bottom of the sealing plate 4. The groove 401 provides a positioning space for the polytetrafluoroethylene plate 5.

[0046] Insert the locking assembly 7 into the countersunk hole of the polytetrafluoroethylene plate 5, push the locking assembly 7 upward, insert the second insertion rod 702 on the locking assembly 7 into the insertion hole 602, the conical block 703 continues to move upward, and pushes the trapezoidal block 605 to move inside the fixing groove 603, compressing the thrust spring 606;

[0047] When the conical block 703 moves to the top of the trapezoidal block 605, the thrust spring 606 releases energy to push the trapezoidal block 605 out of the fixing groove 603. At this time, the top of the trapezoidal block 605 abuts against the bottom of the conical block 703, and the side of the trapezoidal block 605 away from the telescopic rod 604 abuts against the outer surface of the second insertion rod 702 to fix the polytetrafluoroethylene plate 5.

[0048] Then, the upper limit block 102 of the flange plate 1 is inserted into the limit groove 201 of the damping member 2, and the first locking ring 103 is located inside the locking groove 202, so that the connection between the flange plate 1 and the damping member 2 is more reliable and not easy to loosen or fall off. At this time, the first plug rod 104 will be inserted into the process hole 8, ensuring that the relative positions between the damping member 2, the sealing plate 4 and the flange plate 1 are accurate and correct;

[0049] When in use, the plate body 101 is fixed on the superstructure. Since the horizontal friction coefficient of the polytetrafluoroethylene plate 5 is ≤0.4, the skateboard support can effectively isolate most of the seismic energy when an earthquake occurs and reduce the direct impact of seismic waves on the superstructure. The loss-damping ratio of the damping element 2 used is ≥0.2, so that the skateboard support can absorb and consume a large amount of seismic energy during an earthquake, significantly reduce the seismic force on the structure, and protect the building from damage.

[0050] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
