During the rotation of the load-bearing block in the centrifugal energy dissipation structure, a spring connector on one side thereof is subjected to the action of the centrifugal force to generate deformation and energy dissipation. The top of the super high-rise building swings so that the semicircular sliding body forms a state of repeated swinging and rotation in a supporting U-shaped disc, and the concave curved surface structure of the supporting U-shaped disc causes the structure of the present application to return to the axial position, act on the centrifugal energy dissipation structure again, and dissipate energy through the deformation of the spring connector, thereby effectively reducing the curvature of the rotation curve of the top of the super high-rise building in the horizontal plane, that is, reducing the swing amplitude of the top of the super high-rise building.

Description

Technical Field

[0001] The invention belongs to the technical field of building structures, and in particular relates to a centrifugal compound pendulum damping structure for super high-rise buildings and a working method thereof. Background Art

[0002] Wind loads can cause large displacements in super-high-rise buildings. If reasonable shock-absorbing and energy-dissipating measures are not adopted, the structural safety of super-high-rise buildings may be affected. Therefore, some scholars have begun to study damping structures suitable for super-high-rise buildings. Since the top of a super-high-rise building will produce non-directional displacements at any time under the influence of wind loads, the swing of the top of a super-high-rise building in two consecutive time states must be continuous. Combined with the randomness of the swing direction of the top of a super-high-rise building, the motion trajectory of the top of a super-high-rise building swinging in the plane will inevitably reflect the characteristics of a compound pendulum motion. At the same time, the top of a super-high-rise building will also add a certain centrifugal force to the interior of the building during the swing process. However, there are few compound pendulum energy-dissipating damping structures suitable for super-high-rise buildings in this field. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention provides a centrifugal compound pendulum damping structure for super high-rise buildings and a working method thereof, which can effectively weaken the influence of wind load or earthquake load on the top of the super high-rise building and reduce the swing amplitude.

[0004] The present invention is achieved through the following technical solutions:

[0006] One end of the universal hinge abuts against the load-bearing beam, and the other end is fixedly connected to the damping telescopic sleeve rod;

[0007] The centrifugal force conversion section adopts a ratchet sleeve structure, one end of which is rotatably connected to the bottom of the damping telescopic sleeve rod, and the other end is fixedly connected to the first double-circular steel tube concrete combined sleeve and the centrifugal energy dissipation structure in sequence;

[0008] The centrifugal energy dissipation structure comprises a rigid pressure-bearing energy dissipation damper and a connecting block fixedly connected to both ends of the rigid pressure-bearing energy dissipation damper, the four walls of the connecting block are hinged with connecting rods, the connecting rods of the two connecting blocks are arranged in the same vertical direction in a one-to-one correspondence; connecting plates are respectively hinged between the two connecting rods arranged in a one-to-one correspondence; rotating rods, load-bearing blocks and spring connectors are arranged in sequence between the adjacent connecting plates;

[0009] One end of the second double-circular steel tube concrete combined sleeve is fixed to the connecting block on the near side, and the other end is fixed to the semicircular sliding body;

[0010] The free end of the semicircular sliding body abuts against the surface of the supporting U-shaped disc, and the supporting U-shaped disc is a concave curved surface structure.

[0011] Furthermore, the ratchet sleeve structure includes a low-damping spiral strip and a first sleeve and a second sleeve sequentially penetrating the low-damping spiral strip;

[0012] The second sleeve comprises a curved metal sleeve, the inner wall of which is threadedly engaged with the outer wall of the low-damping spiral strip; the outer wall of the curved metal sleeve is provided with a plurality of second steel bar connectors, and the second steel bar connectors are fixedly connected to the inner wall of the second sleeve;

[0013] The outer wall of the second sleeve is provided with a multi-stage convex ratchet, and the inner wall of the first sleeve is provided with a multi-stage pawl corresponding to the multi-stage ratchet of the second sleeve;

[0014] The outer wall of the first sleeve is provided with a first connecting circular plate, the tail of the damping telescopic sleeve rod is rotatably provided with a second connecting circular plate, and the first connecting circular plate is fixedly connected to the second connecting circular plate.

[0015] Furthermore, the first connecting circular plate and the second connecting circular plate are both provided with corresponding connecting holes, and the first connecting circular plate and the second connecting circular plate are respectively bolted to the corresponding connecting holes.

[0016] Furthermore, a rubber stop ring is provided between the second connecting circular plate and the second sleeve.

[0017] Furthermore, the end of the low-damping spiral strip is fixedly connected to the bottom of the universal hinge, and the low-damping spiral strip is made of metal.

[0018] Furthermore, the universal joint is a non-rotatable universal joint.

[0019] Furthermore, the damping telescopic sleeve rod adopts a high-strength metal low-damping telescopic sleeve rod.

[0020] Furthermore, the focus of the point close to the outer edge of the concave disk is lower than the focus of the point close to the inner edge.

[0021] Furthermore, a plurality of supporting ribs are vertically arranged on the bottom of the concave disc, and a pad is fixedly connected to the plurality of supporting ribs.

[0022] A working method of a centrifugal compound pendulum damping structure for a super high-rise building comprises the following steps:

[0023] After the universal hinge is squeezed by the load-bearing beam at multiple angles, the pressure is transmitted to the damping telescopic sleeve rod, and the damping telescopic sleeve rod produces telescopic deformation, and the low-damping spiral strip drives the ratchet sleeve structure in the centrifugal force conversion section to rotate, and in turn drives the first double-circular steel tube concrete combined sleeve and the centrifugal energy dissipation structure to rotate. During the rotation of the load-bearing block in the centrifugal energy dissipation structure, the spring connector on one side thereof is subjected to the centrifugal force to produce deformation and energy dissipation;

[0024] If the top of the super high-rise building swings, the second double-circular steel tube concrete composite sleeve and the semicircular sliding body will form a state of repeated swinging and continuous rotation in one direction in the supporting U-shaped disc. The concave curved surface structure of the supporting U-shaped disc makes the semicircular sliding body tend to return to the axial position, and re-act on the centrifugal energy dissipation structure to dissipate energy through deformation of the spring connector.

[0025] Furthermore, if the top of a super high-rise building swings, and the rotation direction of the projection in the plane is the same as the rotation direction of the centrifugal force conversion section, the centrifugal energy dissipation structure will be subjected to a greater centrifugal force and the rotation speed will be faster;

[0026] If the top of a super high-rise building swings, the rotation direction of the projection in the plane is opposite to the rotation direction of the centrifugal force conversion section. Since the rotation direction of the centrifugal force conversion section is unique, the second double-circular steel tube concrete composite sleeve and the semicircular sliding body rotate in the supporting U-shaped disk in the opposite direction to the super high-rise building. According to the angular momentum balance rule, the rotation speed of the centrifugal energy dissipation structure slows down.

[0027] Compared with the prior art, the present invention has the following beneficial technical effects:

[0028] The present invention provides a centrifugal compound pendulum damping structure for super high-rise buildings and a working method thereof. The universal hinge is used to collect the multi-angle forces between the load-bearing beam and the semicircular sliding body and transmit them to the damping telescopic sleeve rod. The damping telescopic sleeve rod generates telescopic deformation under the force. When the telescopic deformation occurs, the low damping spiral strip can drive the ratchet sleeve structure in the centrifugal force conversion section to rotate. The centrifugal force conversion section drives the first double circular steel tube concrete combination sleeve and the centrifugal energy dissipation structure to rotate in turn. During the rotation of the load-bearing block in the centrifugal energy dissipation structure, the spring connector on one side thereof generates deformation and energy dissipation under the action of the centrifugal force. At the same time, when the second double circular steel tube concrete combination sleeve and the semicircular sliding body continuously swing at the top of the super high-rise building, a state of repeated swinging and rotation will be formed in the supporting U-shaped disc. The concave curved surface structure of the supporting U-shaped disc can make the structure of the present application return to the axial position, act on the centrifugal energy dissipation structure again, and dissipate energy through the deformation of the spring connector. In addition, if the rotation direction of the projection of the top of the super high-rise building in the horizontal plane is the same as the rotation direction of the centrifugal force conversion section, the centrifugal energy dissipation structure will be subjected to a greater centrifugal force and rotate faster. Correspondingly, the deformation degree of the spring connector is correspondingly large, and the energy dissipation efficiency is improved; if the rotation direction of the projection of the top of the super high-rise building in the horizontal plane is opposite to the rotation direction of the centrifugal force conversion section, since the optional installation direction of the centrifugal force conversion section is unique, the direction in which the second double-circular steel tube concrete composite sleeve and the semicircular sliding body rotate in the supporting U-shaped disc is opposite to that of the top of the super high-rise building. According to the angular momentum balance rule, the rotation speed of the centrifugal energy dissipation structure slows down. The rotation direction of the centrifugal energy dissipation structure relative to the projection of the top of the super high-rise building in the horizontal plane is opposite. The centrifugal energy dissipation structure can effectively reduce the curvature of the rotation curve of the top of the super high-rise building in the horizontal plane, that is, reduce the swing amplitude of the top of the super high-rise building, and improve the structural safety performance of the super high-rise building.

[0029] Furthermore, the low-damping spiral strip in the ratchet sleeve structure is threadedly engaged with the inner wall of the second sleeve, which can convert vertical motion into rotational motion, thereby driving the centrifugal energy dissipation structure to dissipate energy.

[0030] Furthermore, the focus of the point close to the outer edge of the concave disc is lower than the focus close to the inner point, ensuring that when the semicircular sliding body slides in the supporting U-shaped disc, the damping telescopic sleeve rod will be subjected to squeezing force and then telescope.

[0031] Furthermore, the universal joint adopts a non-rotatable universal joint, which can ensure that the low-damping spiral strip does not rotate relative to the axis of the entire damping structure of the present application, and then when the relative position of the universal joint and the semicircular sliding body becomes smaller, the low-damping spiral strip can drive the second sleeve to rotate.

[0050] Specifically, the connecting rods 62 hinged on the four walls of the two connecting blocks 61 are arranged mirror-symmetrically along the connecting plate 63; at the same time, there is a connecting plate 63, a load-bearing block 64 and a rotating rod 66 between the adjacent spring connecting members 67;

[0051] Furthermore, the rotation direction of the centrifugal force conversion section 4 is the same as the rotation direction of the rotating rod 66 around the connection point between the rotating rod 66 and the connecting plate 63, so as to maximize the centrifugal force when the centrifugal energy dissipation structure 6 swings at the top of the super high-rise building;

[0052] One end of the second double-circular steel tube concrete combined sleeve 7 is fixedly connected to the connecting block 61 on the near side, and the other end is fixedly connected to the semicircular sliding body 8;

[0053] The free end of the semicircular sliding body 8 abuts against the surface of the supporting U-shaped disc 9, and the supporting U-shaped disc 9 is a concave curved surface structure.

[0054] A preferred embodiment provided by the present invention is as follows: Figure 4 and Figure 5 As shown, the ratchet sleeve structure includes a low-damping spiral strip 12 and a first sleeve 41 and a second sleeve 43 which are sequentially arranged on the low-damping spiral strip 12;

[0055] The second sleeve 43 includes a curved metal sleeve 431, the inner wall of the curved metal sleeve 431 is threadedly engaged with the outer wall of the low-damping spiral strip 12; preferably, the thread spacing between the inner wall of the curved metal sleeve 431 and the outer wall of the low-damping spiral strip 12 is large, thereby ensuring that the relative displacement of the curved metal sleeve 431 on the low-damping spiral strip 12 is relatively smooth;

[0056] The outer wall of the curved metal sleeve 431 is provided with a plurality of second steel bar connectors 432, and the second steel bar connectors 432 are fixedly connected to the inner wall of the second sleeve 43; specifically, the second steel bar connectors 432 are evenly arranged along the outer wall surface of the curved metal sleeve 431;

[0057] The outer wall of the second sleeve 43 is provided with a multi-stage convex ratchet, and the inner wall of the first sleeve 41 is provided with a multi-stage pawl corresponding to the multi-stage ratchet of the second sleeve 43;

[0058] A first connecting circular plate 42 is disposed on the outer wall of the first sleeve 41 , and a second connecting circular plate 31 is disposed at the tail of the damping telescopic sleeve rod 3 . The first connecting circular plate 42 and the second connecting circular plate 31 are fixedly connected.

[0059] Specifically, Figure 6 As shown, the curved metal sleeve 431 is embedded in the second sleeve 43, and the first sleeve 41 and the second sleeve 43 are made of concrete components; specifically, the curved metal sleeve 431 and the second steel bar connector 432 are placed in the second sleeve 43, supported by a mold, and concrete is poured to fix the curved metal sleeve 431, the second steel bar connector 432 and the second sleeve 43.

[0060] Specifically, Figure 7 As shown, a plurality of steel bars are axially embedded in the wall of the first double circular steel tube concrete combined sleeve 5, and the plurality of steel bars extend out from the end connected to the first sleeve 41 to form a third steel bar connector 51, and a plurality of connection holes matching the third steel bar connector 51 are arranged at the end of the first sleeve 41 close to the third steel bar connector 51, which are used for connecting the first double circular steel tube concrete combined sleeve 5 with the first sleeve 41;

[0061] When the centrifugal energy dissipation structure 6 rotates, the two connecting blocks 61 will have a displacement tendency to approach each other, and in this process, the rigid pressure-bearing energy dissipation damper 65 will be compressed and dissipate energy.

[0062] The rigid compressive energy dissipation damper 65 adopts a compressive energy dissipation damper device with large rigidity, which plays an energy dissipation role and connects the two connecting blocks 61 together to ensure that the two connecting blocks 61 can only be displaced in the axial position of the damping structure of the present application.

[0063] Another preferred embodiment provided by the present invention is that the first connecting circular plate 42 and the second connecting circular plate 31 are both provided with corresponding connecting holes, and the corresponding connecting holes on the first connecting circular plate 42 and the second connecting circular plate 31 are respectively connected by bolts;

[0064] Specifically, the first connecting circular plate 42 is a metal component, and is embedded in the end of the outer wall of the first sleeve 41 when the first sleeve 41 is cast; the first connecting circular plate 42 and the second connecting circular plate 31 are coaxially arranged.

[0065] Furthermore, a rubber stop ring 44 is provided between the second connecting circular plate 31 and the second sleeve 43, and the rubber stop ring 44 is used to buffer the maximum vertical displacement of the second sleeve 43 inside the first sleeve 41;

[0066] Specifically, the inner diameter of the damping telescopic sleeve rod 3 is smaller than the outer diameter of the rubber stop ring 44 , ensuring that the rubber stop ring 44 can be always pressed inside the first sleeve 41 by the low-damping telescopic sleeve rod 3 .

[0067] Another preferred embodiment provided by the present invention is that the end of the low-damping spiral strip 12 is fixedly connected to the bottom of the universal hinge 2, and the low-damping spiral strip 12 is made of metal.

[0068] Furthermore, the universal joint 2 is a non-rotatable universal joint or a universal joint that can only rotate at a small angle.

[0069] Furthermore, the damping telescopic sleeve rod 3 is made of a high-strength metal low-damping telescopic sleeve rod.

[0070] Furthermore, the second connecting circular plate 31 is rotatably connected to the low-damping telescopic sleeve rod 3 through a low-damping rotating mechanism, such as a low-damping bearing.

[0071] Another preferred embodiment provided by the present invention is as follows: Fig. 9 As shown, the focus of the point close to the outer edge of the concave disk 9 is lower than the focus close to the inner point, ensuring that when the semicircular sliding body 8 slides in the supporting U-shaped disk 9, the damping telescopic sleeve rod 3 will be subjected to extrusion force and then telescope, so that the centrifugal force conversion section 4 will play a role.

[0072] Another preferred embodiment provided by the present invention is that a plurality of supporting ribs 10 are vertically arranged at the bottom of the concave disc 9 , and a pad 11 is fixedly connected to the plurality of supporting ribs 10 .

[0073] The present invention provides a working method of a centrifugal compound pendulum damping structure for a super high-rise building, comprising the following steps:

[0074] After the universal hinge 2 is squeezed by the bearing beam 1 at multiple angles, the pressure is transmitted to the damping telescopic sleeve 3, and the damping telescopic sleeve 3 produces telescopic deformation, and the low-damping spiral strip 12 drives the ratchet sleeve structure in the centrifugal force conversion section 4 to rotate, and in turn drives the first double-circular steel tube concrete combined sleeve 5 and the centrifugal energy dissipation structure 6 to rotate. During the rotation of the load-bearing block 64 in the centrifugal energy dissipation structure 6, the spring connector 67 on one side thereof produces deformation and energy dissipation under the action of centrifugal force;

[0075] If the top of the super high-rise building swings, the second double-circular steel tube concrete composite sleeve 7 and the semicircular sliding body 8 will form a state of repeated swinging and continuous rotation in one direction in the supporting U-shaped disc 9. The concave curved surface structure of the supporting U-shaped disc 9 makes the semicircular sliding body 8 tend to return to the axial position, and re-act on the centrifugal energy dissipation structure 6 and dissipate energy through deformation through the spring connector 67.

[0076] Furthermore, if the rotation direction of the projection on the horizontal plane of the top of the super high-rise building is the same as the rotation direction of the centrifugal force conversion section 4, the centrifugal energy dissipation structure 6 will be subjected to a greater centrifugal force and a faster rotation speed, and correspondingly, the deformation degree of the spring connector 67 will be correspondingly increased, and the energy dissipation efficiency will be improved;

[0077] If the rotation direction of the projection of the top of the super high-rise building in the horizontal plane is opposite to the rotation direction of the centrifugal force conversion section 4, since the rotation direction of the centrifugal force conversion section 4 is unique, the direction in which the second double-circular steel tube concrete composite sleeve 7 and the semicircular sliding body 8 rotate in the supporting U-shaped disk 9 is opposite to that of the super high-rise building. According to the angular momentum balance rule, the rotation speed of the centrifugal energy dissipation structure 6 slows down. Specifically, the rotation direction of the centrifugal energy dissipation structure 6 is opposite to the projection of the top of the super high-rise building in the horizontal plane. The centrifugal energy dissipation structure 6 can effectively reduce the curvature of the rotation curve of the top of the super high-rise building in the horizontal plane, that is, reduce the swing amplitude of the top of the super high-rise building, and improve the structural safety performance of the super high-rise building.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

A working method of a centrifugal compound pendulum damping structure for a super high-rise building, characterized in that: A centrifugal compound pendulum damping structure for a super high-rise building according to any one of claims 1 to 5, comprising the following steps: After the universal hinge (2) is squeezed at multiple angles by the load-bearing beam (1), the pressure is transmitted to the damping telescopic sleeve (3), and the damping telescopic sleeve (3) generates telescopic deformation, and the low-damping spiral strip (12) drives the ratchet sleeve structure in the centrifugal force conversion section (4) to rotate, and in turn drives the first double-circular steel tube concrete combined sleeve (5) and the centrifugal energy dissipation structure (6) to rotate. During the rotation of the load-bearing block (6) in the centrifugal energy dissipation structure (6), the spring connector (67) on one side thereof generates deformation and energy dissipation under the action of the centrifugal force; If the top of the super high-rise building swings, the second double-circular steel tube concrete composite sleeve (7) and the semicircular sliding body (8) will form a state of repeated swinging and continuous rotation in one direction in the supporting U-shaped disc (9). The concave curved surface structure of the supporting U-shaped disc (9) causes the semicircular sliding body (8) to tend to return to the axial position and act on the centrifugal energy dissipation structure (6) again and dissipate energy through deformation through the spring connector (67).

7. A working method of a centrifugal compound pendulum damping structure for a super high-rise building according to claim 6, characterized in that: If the top of the super high-rise building sways and the rotation direction of the projection in the plane is the same as the rotation direction of the centrifugal force conversion section (4), the centrifugal energy dissipation structure (6) will be subjected to a greater centrifugal force and the rotation speed will be faster; If the top of the super high-rise building swings, the rotation direction of the projection in the plane is opposite to the rotation direction of the centrifugal force conversion section (4). Since the rotation direction of the centrifugal force conversion section (4) is unique, the second double-circular steel tube concrete composite sleeve (7) and the semicircular sliding body (8) rotate in the supporting U-shaped disc (9) in the opposite direction to the super high-rise building. According to the angular momentum balance rule, the rotation speed of the centrifugal energy dissipation structure (6) slows down.
