Description

TECHNICAL FIELD

[0001] The present application relates to the field of building structure anti-seismic technology, and particularly provides a double-mechanism energy dissipation damper convenient to replace. BACKGROUND

[0002] Metal dampers, as a common energy dissipation device, are widely used in building structures. During an earthquake, the dampers can concentrate the seismic energy to reduce the damage of the main building structure components, thereby improving the seismic capacity of the building structure.

[0003] Currently, the commonly used metal dampers include shear metal dampers, bending metal dampers, and buckling-restrained energy dissipation braces. The shear metal dampers are prone to out-of-plane deformation under large deformation, which reduces the carrying capacity and energy dissipation capacity of the damper. The bending metal dampers have strong deformation capacity, but have low initial stiffness. The buckling-restrained energy dissipation braces need to eliminate the bonding force between the energy dissipation core and the buckling-restrained part, which is difficult to design.

[0004] The replacement difficulty of the above three kinds of metal dampers depends on the size of the installation space under the deformation of the building structure. When the replacement space is limited and exceeds the replaceable range, large-scale instruments need to be used for reaming or mechanical cutting to complete the disassembly, which is difficult to replace. Moreover, the entire damper needs to be disassembled during replacement, which is low in replacement efficiency. SUMMARY

[0005] The present application provides a double-mechanism energy dissipation damper convenient to replace, which solves the problem that the metal damper in the prior art is difficult to replace under the deformation of the external structure.

[0010] According to the damper provided by the present invention, square heads are formed at both ends of the energy-absorbing rod, the end of the energy-absorbing rod close to the adapter can be loosely fitted with the square hole, and the end away from the adapter passes through the second support member and is detachably connected to the shift rod.

[0011] According to the damper provided by the present invention, the second friction member and the shifting rod are both provided with long holes along the length direction, and the synchronization rod passes through the long holes to connect the shifting rod and the second friction member.

[0012] According to the damper provided by the present invention, the bottom plate is provided with a sliding groove along the length direction; The clamping plate includes a fixed plate and a movable plate, and a slider is provided at the bottom of the movable plate, and the slider cooperates with the sliding groove; A screw is provided in the slide groove along the length direction of the slide groove, and the screw passes through the slider; The screw rod is threadedly connected with a locking nut in a direction away from the slider.

[0027] The technical solutions of the present application are described below in conjunction with the embodiments shown in the drawings: Figures 1 to 11 The embodiments of the present application provide a double-mechanism energy dissipation damper convenient to replace, as shown in Figure 1 、 Figure 2 and Figure 3 , comprising a bottom plate 1, a first support 2, a second support 3, an adapter 4, an energy dissipation rod 5, a clamping plate 6, a first friction piece 7, a second friction piece 8, a push rod 9 and a synchronization rod 10. ​Among them, the first support member 2 is arranged on the base plate 1; the second support member 3 is arranged on the base plate 1; the adapter 4 is connected to the first support member 2 and is arranged on the side facing the second support member 3; one end of the energy-absorbing rod 5 is non-rotatably detachably connected to the adapter 4, and the other end is rotatably detachably connected to the second support member 3; there are at least two splints 6, which are arranged in parallel to the base plate 1; there are at least two first friction members 7, which are detachably connected to the opposite surfaces of the splints 6; the second friction member 8 is rotatably arranged between the two first friction members 7 and abuts against the two first friction members 7; the rotation axis of the second friction member 8 is colinear with the axis of the energy-absorbing rod 5; the shift rod 9 is non-rotatably connected to the energy-absorbing rod 5 and is detachably installed on the end of the energy-absorbing rod 5 away from the adapter 4; the synchronization rod 10 is respectively connected to the second friction member 8 and the shift rod 9, for synchronously driving the second friction member 8 and the shift rod 9 to rotate.

[0028] In some embodiments, the first support member 2 and the second support member 3 can be of other shapes such as an arch, so that the various components of the damper can be connected and assembled; the first friction member 7 can be installed on the adjacent side of the splint 6, and the first friction member 7 and the splint 6 can bear each other's effects, that is, in some embodiments, the installation positions of the first friction member 7 and the splint 6 can be swapped. During the shock absorption process, the first friction member 7 and the second friction member 8 are subjected to external force and generate friction with each other, offsetting part of the external force applied to the damper, thereby improving the load-bearing capacity of the damper. The energy-absorbing rod 5 is relatively subjected to less external force, so that the energy-absorbing rod 5 will not easily undergo large bending deformation, which is conducive to the subsequent disassembly and replacement of the energy-absorbing rod 5. Therefore, the first friction member 7 and the splint 6 can bear each other's role in the shock absorption process; In this embodiment, if Figure 1 As shown, the first support member 2 and the second support member 3 are direction blocks, which are fixedly installed on the base plate 1; the adapter 4 is connected to the first support member 2 and is arranged on the side facing the second support member 3, so that the parts connected to the adapter 4 are between the first support member 2 and the second support member 3; one end of the energy-absorbing rod 5 is non-rotatably connected to the adapter 4, and the other end is rotatably detachably connected to the second support member 3. During the shock absorption process, due to the rotation of the lever 9, the connection end of the energy-absorbing rod 5 and the second support member 3 has a rotation tendency. Since the energy-absorbing rod 5 and the second support member 3 are rotatably detachably connected, the energy-absorbing rod 5 only undergoes circumferential deformation under the rotation tendency, and will not suddenly undergo large bending deformation, which is conducive to the subsequent replacement of the energy-absorbing rod 5; The second friction member 8 is arranged between the first friction member 7, and the clamping plate 6 is arranged parallel to the bottom plate 1. Through the arrangement of the clamping plate 6, the first friction member 7 and the second friction member 8 can fit closely, thereby increasing the friction between the first friction member 7 and the second friction member 8, further sharing the external force exerted on the energy-absorbing rod 5 during the shock absorption process, and protecting the energy-absorbing rod 5 from sudden large bending deformation.

[0029] The rotation axis of the second friction member 8 is collinear with the axis of the energy-absorbing rod 5. When the second friction member 8 has a tendency to rotate, the rotation axis of the second friction member 8 and the axis of the energy-absorbing rod 5 are collinear, that is, the energy-absorbing rod 5 passes through the second friction member 8 coaxially. Therefore, the friction generated by the second friction member 8 and the first friction member 7 will not act on the energy-absorbing rod 5, so that the energy-absorbing rod 5 will not be easily bent and deformed, which is conducive to the later disassembly and replacement of the energy-absorbing rod 5 and reduces maintenance time. The friction generated between the first friction member 7 and the second friction member 8 is applied to the building structure by the synchronous rod 10, thereby relatively improving the load-bearing capacity of the damper. An embodiment of the present invention provides a dual-mechanism energy-absorbing damper that is easy to replace. By improving the traditional metal damper into an energy-absorbing damper having an energy-absorbing rod 5 and a friction assembly, dual-mechanism energy absorption can be achieved, thereby more effectively reducing the shock of the building structure. At the same time, through the torsional damping of the energy-absorbing rod 5, the energy-absorbing rod 5 can be torsionally deformed only in the circumferential direction without any large bending deformation. In this way, the huge deformation of the material of the traditional metal damper is avoided, thereby avoiding the problem of difficult replacement of consumables.

[0030] Furthermore, the energy-absorbing rod 5 and the friction assembly are both configured as detachable structures, which can realize the rapid installation and removal of the damping consumable parts independently, thereby improving the working efficiency and avoiding the problem of needing to disassemble the entire damper when replacing the traditional metal damper.

[0031] According to the double mechanism energy dissipation damper provided by the embodiment of the present invention, Figure 3 As shown, the contact surface between the first support member 2 and the adapter member 4 is a plane, and the first support member 2 and the adapter member 4 are respectively provided with a plurality of first arc-shaped slots 11; the plurality of first arc-shaped slots 11 in the same plane are on the same circle; The first fastening component 12 is further included. The first fastening component 12 passes through the first arc-shaped slot 11 and is used to connect the first support member 2 and the adapter member 4 .

[0032] It is understandable that the first fastening assembly 12 can be a combination of screws and washers, which penetrate the adapter 4 and are embedded in the first support member 2 to connect the first support member 2 and the adapter 4, or other connection structures can be used in combination to connect the first support frame 2 and the adapter 4. In this embodiment, if Figure 3As shown, the first fastening assembly 12 is preferably a combination of bolts, nuts and washers, and is connected with the first arc-shaped slot 11, so that after the damper is deformed in an earthquake disaster, the various components can still be disassembled, installed and replaced; the contact surface between the first support member 2 and the adapter 4 is flat, ensuring that the connection is firm, and when subjected to external force, the energy dissipation rod 5 will not bend in the direction close to the first support member 2, ensuring the normal use of the damper; the first support member 2 and the adapter 4 are both correspondingly provided with a plurality of first arc-shaped slots 11, and the first arc-shaped slots 11 are provided. When the energy dissipation rod 5 rotates when the lever 9 rotates, the first fastening assembly 12 generates friction on the first arc-shaped slot 11 during the shock absorption process, which is used to share the external force on the energy dissipation rod 5; The multiple first arc-shaped slots 11 in the same plane are on the same circle. After the earthquake disaster, if the adapter 4 is offset, the first arc-shaped slots 11 can be used to assemble the components at different angles from the original installation angles. During the shock absorption process, when subjected to external force, the friction force generated on the first fastening component 12 is the same in the same plane, and because of the arc shape, the friction force generated by the first fastening component 12 at the end points of the slot will offset part of the vertical friction force, and will not cause the energy-absorbing rod 5 to be subjected to torsional forces of different sizes near the first support member 2, thereby avoiding bending or twisting of the energy-absorbing rod 5.

[0033] According to the double mechanism energy dissipation damper provided by the embodiment of the present invention, Figure 4 and Figure 5 As shown, the adapter 4 is provided with a square hole 401 for non-rotatably detachably connecting with the energy-dissipating rod 5 .

[0034] In some embodiments, the square hole 401 can be a square hole, a pentagonal hole, a hexagonal hole or other hole shapes, as long as the energy dissipation rod 5 can prevent rotation at the adapter 4 under external force conditions; In this embodiment, since one end of the energy-absorbing rod 5 is rotatably connected to the second support member 3, the square hole 401 is provided on the adapter 4. Thus, when the lever 9 rotates to drive the energy-absorbing rod 5 to rotate, rotational friction is generated at the square hole 401 of the adapter 4, so that the energy-absorbing rod 5 only undergoes torsional deformation in the circumferential direction. At the same time, the adapter 4 and the energy-absorbing rod 5 are detachably connected, which facilitates the replacement of the energy-absorbing rod 5 after torsional deformation.

[0035] According to the double mechanism energy dissipation damper provided by the embodiment of the present invention, Figure 3 、 Figure 6 and Figure 7 As shown, the clamping plate 6 is arranged between the first support member 2 and the second support member 3, and the energy-dissipating rod 5 passes through the clamping plate 6, the first friction member 7 and the second friction member 8 respectively; The second friction member 8 is provided with a plurality of second arc-shaped slots 13 , and the plurality of second arc-shaped slots 13 are on the same circle, which is concentric with the energy-absorbing rod 5 ; It also includes a second fastening assembly 14 , which passes through the second arc-shaped slot 13 , the first friction member 7 and the clamping plate 6 respectively, and is used to fasten the second arc-shaped slot 13 , the first friction member 7 and the clamping plate 6 .

[0036] It is understood that the first friction member 7 and the second friction member 8 can be made of steel materials of various specifications, and their adjacent friction surfaces have protrusions of similar shapes, or they can be grinding wheels with granular materials on their adjacent friction surfaces. For example, the protrusions on the first friction member 7 and the second friction member 8 can be various small diamond-shaped, conical, or other shapes that can increase the friction between the first friction member 7 and the second friction member 8. like Figure 7 A friction member is shown, wherein the surfaces of the two first friction members 7 are both provided with arc-shaped protrusions along the circumferential direction, and the corresponding arc-shaped protrusions of the same specifications are provided on the bottom friction surface of the second friction member 8. The two first friction members 7 are engaged with the protruding areas on the bottom of the second friction member 8. The clamping of the clamping plate 6 makes the first friction members 7 and the second friction members 8 fit tightly together. The arc-shaped protrusions increase the friction force between the first friction members 7 and the second friction members 8 to offset the external force applied to the damper during the shock absorption process, protecting the energy dissipation rod 5 from being suddenly subjected to excessive external force, resulting in excessive bending deformation; It is understood that the second fastening assembly 14 can be a combination of a screw, a washer, etc., which penetrates the second arc-shaped slot 13 and is embedded in the clamping plate 6 to fasten the second arc-shaped slot 13, the first friction member 7, and the clamping plate 6, or other connection structures can be used in combination to fasten the second arc-shaped slot 13, the first friction member 7, and the clamping plate 6; In this embodiment, if Figure 3 and Figure 6 As shown, the second fastening assembly 14 is preferably a combination of a stud, a nut, and a washer. The first friction member 7 and the second friction member 8 are located between the clamping plate 6. The second arc-shaped slot 13, the first friction member 7, and the clamping plate 6 are fastened by the second fastening assembly 14, so that the clamping plate 6 makes the first friction member 7 and the second friction member 8 fit closely together, thereby increasing the friction force between the first friction member 7 and the second friction member 8; the energy dissipation rod 5 passes through the clamping plate 6, the first friction member 7, and the second friction member 8. During the shock absorption process, the friction force between the first friction member 7 and the second friction member 8 is transmitted to the building structure by means of the synchronization rod 10, thereby improving the load-bearing capacity of the damper and ensuring that the energy dissipation rod 5 does not suffer from large bending deformation, which is convenient for subsequent disassembly and replacement. The second friction member 8 is provided with a plurality of second arc-shaped slots 13, and the plurality of second arc-shaped slots 13 are on the same circle, which is concentric with the energy-absorbing rod 5. The second arc-shaped slots 13 are provided. During the shock absorption process, the second friction member 8 is rotated by the synchronization rod 10, and the rotation tendency generated causes the second fastening assembly 14 to generate friction at the second arc-shaped slots 13, thereby sharing the external force exerted on the energy-absorbing rod 5 and protecting the energy-absorbing rod 5 from large deformation or bending. At the same time, because it is an arc-shaped slot, the friction force generated by the second fastening assembly 14 on the second arc-shaped slot 13 will offset part of the vertical friction force at the end point of the slot, so that after the damper is deformed during the earthquake, the second arc-shaped slots 13 can be used to assemble the various components at different installation angles from the original.

[0037] According to the double mechanism energy dissipation damper provided by the embodiment of the present invention, Figure 4 、 Figure 5 and Figure 8 As shown, a square head 501 is formed at both ends of the energy-absorbing rod 5. The end of the energy-absorbing rod 5 close to the adapter 4 can be loosely matched with the square hole 401, and the end away from the adapter 4 passes through the second support member 3 and is detachably connected to the lever 9.

[0038] In this embodiment, both ends of the energy-absorbing rod 5 are square heads 501, one end cooperates with the square hole 401, and the other end passes through the second support member 3 and is detachably connected to the lever 9. During the shock absorption process, the friction forces generated by the two ends of the energy-absorbing rod 5 due to the cooperation relationship of the square heads 501 are all circumferential friction forces, and only the two ends of the energy-absorbing rod 5 are deformed, preventing the energy-absorbing rod 5 from suddenly bending or other excessive deformations. At the same time, due to the cooperation relationship between the square head 501 and the first support member 2 and the second support member 3, the energy-absorbing rod 5 is convenient to disassemble and replace.

[0039] According to the double mechanism energy dissipation damper provided by the embodiment of the present invention, Figure 3 As shown, the second friction member 8 and the shifting rod 9 are both provided with long holes along the length direction, and the synchronization rod 10 passes through the long holes to connect the shifting rod 9 and the second friction member 8.

[0040] In this embodiment, the long holes are opened along the length direction on the second friction member 8 and the shift rod 9. During the shock absorption process, the friction force generated on the synchronization rod 10 in the long holes due to the external force is in the vertical direction, which will not cause the entire damper to have a tendency to fold. In addition, the synchronization rod 10 can transmit the external force exerted on the shift rod 9 to the second friction member 8. At the same time, the friction force generated by the synchronization rod 10 in the long holes of the second friction member 8 and the shift rod 9 shares the external force exerted on the second friction member 8 and the shift rod 9, thereby further improving the load-bearing capacity of the damper.

[0041] According to the double mechanism energy dissipation damper provided by the embodiment of the present invention, Figure 9 and Figure 10As shown, the bottom plate 1 is provided with a slide groove 15 along the length direction; The clamping plate 6 includes a fixed plate 601 and a movable plate 602. The bottom of the movable plate 602 is provided with a slider 16, and the slider 16 cooperates with the slide groove 15. A screw 17 is provided in the slide groove 15 along the length direction of the slide groove 15 , and the screw 17 passes through the slider 16 ; The screw rod 17 is threadedly connected with a locking nut 18 in a direction away from the slider 16 .

[0042] In this embodiment, the slide 15, the slider 16, the screw 17 and the locking nut 18 together constitute the clamping plate adjustment mechanism. Figure 9 As shown, the fixed plate 601 of the clamping plate 6 is fixedly connected to the base plate 1. The base plate 1 has a sliding groove 15 along its length. The sliding groove 15 extends from the movable plate 602 of the clamping plate 6 to the bottom of the lever 9. A screw 17 is provided in the sliding groove 15 along its length. The movable plate 602 of the clamping plate 6 is connected to the slider 16, so that the slider 16 carries the movable plate 602 of the clamping plate 6 and moves back and forth on the screw 17, thereby increasing the distance between the two plates of the clamping plate 6. After the first friction member 7 and the second friction member 8 are placed, the movable plate 602 of the clamping plate 6 is moved to fit tightly with the first friction member 7. The locking nut 18 on the screw 17 is twisted to abut the movable end of the clamping plate 6, thereby locking the first friction member 7, the second friction member 8 and the clamping plate 6. This clamping plate 6 allows first friction members 7 and second friction members 8 of various specifications to be suitable for the damper, eliminating the need for special specifications of friction members. This avoids the need to prepare special specifications of friction members for later maintenance and replacement, reducing the manufacturing cost of the first friction members 7 and the second friction members 8. It is understandable that multiple groups of clamping plate adjustment mechanisms can be provided on the base plate 1 to achieve a tight fit between the first friction member 7 , the second friction member 8 and the clamping plate 6 .

[0043] According to the double mechanism energy dissipation damper provided by the embodiment of the present invention, Figure 3 As shown, the second friction member 8 is plate-shaped, and the first friction member 7 is disc-shaped.

[0044] In this embodiment, the first friction member 7 is a disc-shaped structure clamped between the clamping plate 6 and the second friction member 8. During the shock absorption operation, the friction force between the first friction member 7 and the second friction member 8 is transmitted to the building structure by the synchronization rod 10, thereby improving the load-bearing effect of the damper. At the same time, the disc-shaped design of the first friction member 7 is conducive to its disassembly and replacement after the earthquake disaster.

[0045] According to the double mechanism energy dissipation damper provided by the embodiment of the present invention, Figure 3 As shown, the surface of the first friction member 7 is sprayed with a wear-resistant coating.
