Description

Technical Field

[0001] The present application relates to the technical field of building shock absorption, and in particular to a damping device for an island reef outpost building. Background Art

[0002] Deep-sea islands and reefs present harsh environments, with frequent typhoons and challenging regulatory oversight. They require structures that reduce the natural vibration period and dissipate energy in multiple directions to cope with various emergencies. Traditional tall steel structures, with varying shapes, suffer from weak vibration resistance and long natural vibration periods. This is especially true for tall structures on deep-sea islands and reefs, where typhoons frequently affect the structure and vibration, necessitating the installation of damping devices. However, most studies on damping devices show that these devices, due to structural limitations, have a single energy dissipation method and lack universal applicability.

DETAILED DESCRIPTION

[0058] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0059] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0060] In the description of the present invention, it should be noted that, unless otherwise specified or limited, the terms "mounted" and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0061] like Figures 1 to 9As shown, an embodiment of the present application provides a damping device for an island outpost building, comprising: a fixed seat 1, a rotating seat 2, a rotational energy absorber 3 and a plurality of linkage rods 4. The building generally comprises a column 9 and a beam 8 connecting the column 9. The fixed seat 1 can be connected to the beam 8 of the building, the rotating seat 2 can be rotatably connected to the fixed seat 1, and a plurality of lifting guide grooves 221 are provided on the rotating seat 2, each lifting guide groove 221 being arranged in sequence at intervals around the circumference of the rotating seat 2, and the lifting guide grooves 221 extend radially along the rotating seat 2. The rotational energy absorber 3 is provided on the fixed seat 1 or the rotating seat 2, and one end of each linkage rod 4 is respectively connected to the column 9 of the building, and the other end of each linkage rod 4 is respectively slidably connected to the corresponding lifting guide groove 221 on the rotating seat 2.

[0062] When the linkage rod 4 pushes the rotating seat 2 to rotate around the fixed seat 1, the rotational energy absorber 3 can elastically abut against the rotating seat 2 or the fixed seat 1 to dissipate external impact energy. When the linkage rod 4 slides along the lifting guide groove 221, the linkage rod 4 can move along the arrangement direction of the fixed seat 1 and the rotating seat 2, that is, along the thickness direction of the rotating seat, abutting against the fixed seat 1 to dissipate external impact energy. The damping device of the present application has a multi-directional energy dissipation effect, reducing the torsional vibration period of the building.

[0063] The damping device for island and reef outpost buildings provided in the embodiments of this application can be applied to high-rise outpost buildings on deep-sea islands and reefs. The damping device for island and reef outpost buildings provided in this application has the advantages of reducing the building's natural vibration period and facilitating assembly and disassembly. It is also well-suited for use as a typhoon-resistant supporting facility for high-rise outpost buildings on typhoon-prone islands.

[0064] In some possible embodiments, the fixed base 1 includes an elastic plate and a base plate 15, the base plate 15 and the elastic plate being spaced apart and connected to each other, forming a gap between the base plate 15 and the elastic plate. The rotating base 2 is rotatably disposed within the gap. A lifting guide groove 221 is provided on the side of the rotating base 2 facing the elastic plate. A friction block 411 is provided at the end of the linkage rod 4. One end of the linkage rod 4 is located between the rotating base 2 and the elastic plate, and the friction block 411 is slidably accommodated in the lifting guide groove 221. When the friction block 411 slides along the lifting guide groove 221, the linkage rod 4 moves along the thickness direction of the rotating base to squeeze or move away from the elastic plate, thereby absorbing external impact energy through the elastic plate, protecting the building structure and preventing serious damage to the building structure. The friction block 411 slides to different heights of the lifting guide groove 221 according to the amplitude of the building structure, generating different energy consumption values.

[0065] In some possible embodiments, such as Figure 2 、 Figure 7 and Figure 8As shown, the depth of the lifting guide groove 221 gradually decreases from the middle to the ends of the lifting guide groove 221. That is, in the radial direction of the rotating base 2, the middle of the lifting guide groove 221 is deep, while the depth on both sides gradually decreases. When there is no external impact (such as a typhoon), the friction block 411 provided at the end of the linkage rod 4 is located in the middle of the lifting guide groove 221. The linkage rod 4 and the elastic plate have a gap or, although in contact, the extrusion force is relatively small. When the building deforms, it can drive the linkage rod 4 to move synchronously, and the friction block 411 can slide from the middle to one side (either side) along the lifting guide groove 221. During this process, the end of the linkage rod 4 will gradually rise, elastically abutting the elastic plate, absorbing energy through the elastic plate to resist external impact forces.

[0066] In some possible embodiments, the rotating base 2 includes a main body 21, a plurality of sliding friction devices 22, and a plurality of guide shells 23. Each sliding friction device 22 is disposed on a side of the main body 21 near the elastic plate. The sliding friction devices 22 are spaced apart along the circumference of the main body 21. Each sliding friction device 22 is provided with a lifting guide slot 221. Each guide shell 23 is connected to a corresponding sliding friction device 22. The guide shell 23 has a lifting slot extending along the thickness of the rotating base 2, extending from the sliding friction device 22 toward the elastic plate. The linkage rod 4 includes a rod portion, to which a friction block 411 is connected. The rod portion is slidably received in the lifting slot, and the friction block 411 is slidably received in the lifting guide slot 221. As the friction block 411 slides along the lifting guide slot 221, it rises and falls. The rod body of the linkage rod 4 slides up and down along the lifting slot, squeezing or releasing the elastic plate, which in turn applies corresponding pressure in the opposite direction.

[0067] The sliding friction device 22 can be a rectangular steel plate with a lifting guide groove 221. The rectangular steel plate with different roughness can be replaced according to the energy consumption needs. The friction energy consumption value can be changed independently according to the lateral displacement value of the building. In conjunction with the extrusion of the elastic plate, the greater the displacement of the support rod, the greater the extrusion force it receives, the greater the friction force, and the more friction energy consumption.

[0068] In some possible embodiments, combined Figure 7 and Figure 8 As shown, each sliding friction element 22 can be provided with a lifting guide groove 221. The lifting guide groove 221 comprises multiple parallel slits, each of which is narrow and deep in the middle and gradually shallower at the sides. The friction block 411 comprises multiple friction plates, each of which is embedded in a corresponding narrow groove. This increases the friction contact surface between the friction block 411 and the sliding friction element 22.

[0069] The friction plate can be semicircular, and can be replaced with friction plates of different roughness according to the energy consumption requirements of the building to change the friction energy consumption value. The friction and sliding energy can be consumed by the semicircular friction plate and the lifting guide groove 221 on the rotating seat 2.

[0070] In some possible embodiments, combined Figure 3 and Figure 4 As shown, the elastic plate includes a first plate body 11, a second plate body 12, an elastic sheet 13, and a pressure alarm 14. The pressure alarm 14 is located at the edge of the elastic sheet and is connected to the elastic sheet 13. The elastic sheet 13 is located between the first plate body 11 and the second plate body 12. A gap is formed between the second plate body 12 and the bottom plate 15. When the elastic sheet is compressed, the pressure alarm 14 can be triggered to sound an alarm. In this embodiment of the application, by providing a pressure alarm 14 on the elastic sheet 13, an alarm can be triggered when the elastic sheet 13 is compressed, providing a timely warning of damage to the building caused by vibration, thereby improving the safety of the building. A groove 131 can be provided on the edge of the elastic sheet 13 to facilitate the assembly of the pressure alarm 14.

[0071] Combine Figure 4 and Figure 5 As shown, the elastic sheet 13 can be a rubber sheet. The pressure alarm 14 is mounted within a groove 131 along the edge of the rubber sheet. When the building vibrates, the linkage rod 4 squeezes the elastic sheet, and thus the rubber sheet. When the squeezing force reaches a certain level, the rubber sheet deforms severely, causing the pressure alarm 14 to transmit an alarm signal. This structural design improves building safety redundancy and provides timely warning of impending damage.

[0072] like Figure 5 and Figure 9 As shown, the pressure alarm 14 may include an alarm body 141 and a pressure sensor 142. A groove 131 is provided on the edge of the elastic sheet 13, and the pressure sensor 142 is disposed within the groove 131. The alarm body 141 is located on the edge of the elastic sheet 13 and is fixed to the edge of the elastic sheet 13 by bonding or fasteners. When the building vibrates, the linkage rod 4 squeezes the elastic plate, that is, the elastic sheet 13. When the squeezing force reaches a certain level, the elastic sheet 13 severely deforms, triggering the pressure sensor 142, causing it to send an alarm signal.

[0073] In some possible implementation schemes, the elastic plate and the rotating seat 2 may both be polygonal, and the sliding friction device 22 and the linkage rod 4 may be provided at the position of each side of the polygon corresponding to the damping device.

[0074] In some possible implementations, the damping device of the island and reef outpost structure includes multiple connecting rods 6. The rotating base 2 is provided with multiple arcuate slots 24, each extending along the circumference of the rotating base 2 and spaced apart along the circumference of the rotating base 2. Each connecting rod 6 extends through the arcuate slot 24, the base plate 15, and the elastic plate of the rotating base 2. The connecting rods 6 are provided with first and second side limiters, which are respectively limited by the base plate 15 and the elastic plate. When the rotating base 2 rotates relative to the fixed base 1, the connecting rods 6 slide along the arcuate slots 24.

[0075] The damping device of the island outpost structure can also include a central axis, which passes through the elastic plate, the base plate 15 and the rotating seat 2. The rotating seat 2 can rotate around the central axis. Each connecting rod 6 is located on the circumferential side of the central axis. Circular holes are provided on the elastic plate and the base plate 15. The connecting rod 6 passes through the circular holes relative to each other, and the elastic plate and the base plate 15 cannot rotate relative to each other. The connecting rod 6 can be a screw, and the first side limiter and the second side limiter can both be nuts that are threadedly connected to the connecting rod 6. The tightness between the elastic plate, the base plate 15 and the rotating seat 2 can be adjusted by screwing the first side limiter and the second side limiter.

[0076] It should be noted that the first side limiter is the top limiter, the fixed seat 1 and the rotating seat 2 are both located below the beam 8, the connecting rod 6 can pass through the beam 8 of the building, and the first side limiter can be located above the beam 8.

[0077] In some possible embodiments, combined Figure 4 and Figure 8 As shown, the rotation energy dissipator 3 is disposed on the rotating seat 2 and is located at both ends of the arc groove 24 . When the rotating seat 2 rotates relative to the fixed seat 1 , the connecting rod 6 can abut against the rotation energy dissipator 3 .

[0078] The rotary energy dissipator 3 can be equipped with a rotary alarm. This alarm consists of a push rod extending from the rotary energy dissipator 3, with a U-shaped member at its end. When the rotating base 2 rotates relative to the fixed base 1, the connecting rod 6 moves into the U-shaped member, exerting effective force on the rotary energy dissipator 3 and simultaneously triggering the rotary alarm. For example, when the compressive force on the push rod of the rotary alarm reaches a certain value, the rotary alarm transmits an alarm signal. This, in conjunction with the pressure alarm, enhances the building's safety redundancy and provides timely warning of impending damage.

[0079] In some possible embodiments, such as Figure 4 As shown, a ball 5 is disposed between the rotating seat 2 and the base plate 15. The base plate 15 may be a circular structure with ribs disposed along its circumferential edges to prevent the ball 5 from being moved out. The ball 5 contacts the base plate 15 and the rotating seat 2 on its upper and lower sides, respectively, converting the sliding friction between the rotating seat 2 and the base plate 15 into rolling friction, thereby reducing frictional losses between the two.

[0080] In some possible implementation schemes, the damping device of the island outpost building may include a torque absorber 7, which is located between the rotating seat 2 and the fixed seat 1 and is respectively connected to the rotating seat 2 and the fixed seat 1. When the rotating seat 2 rotates relative to the fixed seat 1, the deformation of the torque absorber 7 increases.

[0081] The damping device of the island outpost building can include multiple torque absorbers 7, each of which is spaced apart in sequence around the circumference of the rotating base 2. When the building twists under external impact, the rotating base 2 is driven to rotate through the linkage rod 4, and the torque absorbers 7 are stretched to dissipate energy, thereby improving the building's natural vibration period and increasing the segmented energy dissipation path of the building. When the building's natural vibration period is too large, the pressure alarm 14 and the rotation alarm are subjected to increased force, transmitting an alarm signal and triggering an alarm, providing a timely warning of damage to the building caused by vibration, thereby improving the building's safety.

[0082] The rotating base 2 and the elastic plate can both be polygonal plate structures. Torque dissipators 7 can be arranged at the corners of the rotating base 2 and the elastic plate. Hinge supports can be provided at the corners of the rotating base 2 and the elastic plate. The torque dissipators 7 can be hard springs or other dampers that dissipate energy through tension. The ends of the torque dissipators 7 are respectively connected to the hinge supports at the corners of the rotating base 2 and the elastic plate. When the rotating base 2 rotates and displaces relative to the elastic plate, the torque dissipators 7 are activated to dissipate energy through tension.

[0083] In some possible embodiments, the linkage rod 4 includes a spring rod 42, a first support rod 41 and a second support rod 43. The spring rod 42 is located between the first support rod 41 and the second support rod 43, and is respectively connected to the first support rod 41 and the second support rod 43. The first support rod 41 is slidably connected to the lifting guide groove 221, and the second support rod 43 is used to connect to the building column 9.

[0084] The first support rod 41 and the second support rod 43 can both be hollow steel tubes. The second support rod 43 can be fixed to the building column 9 via a special-shaped fixing steel member 431. The present application provides multiple linkage rods 4, each extending in a different direction, thereby improving energy dissipation efficiency. The support rods are connected by a hard spring rod 42, which can adapt to different vibration directions of the building. The spring rod 42 has a certain energy dissipation function. In conjunction with the friction block 411, it can achieve segmented energy dissipation, thereby improving the building's vibration resistance.

[0085] The present invention also provides a construction method for the damping device of the above-mentioned island reef outpost building, which mainly includes the following steps:

[0086] Step S10: Connect the linkage rod 4 to the top of the column 9 through the special-shaped fixed steel member 431;

[0087] Step S20: Install the piezoresistor in the pressure alarm 14 in the groove reserved in the elastic sheet 13 (rubber sheet), then clamp the elastic sheet 13 between two hexagonal steel plates 8 (first plate 11 and second plate 12), and connect it to the floor or beam 8 of the building via a connecting rod 6 (such as a bolt);

[0088] Step S30: The rotating base 2 is passed through the connecting rod 6 through the arc groove 24, and then the end of the linkage rod 4 with the friction plate is engaged with the lifting guide groove 221 of the sliding friction device 17, and is clamped by the elastic plate and the rotating base 2;

[0089] Step S40: Install the rotary energy absorber 3 on the rotating base 2 on the left and right sides of the connecting rod 6 so that the push rod of the rotary energy absorber 3 is aligned with the sliding direction of the connecting rod 6;

[0090] Step S50: Install the torque absorber 7 on the hinge support at the corner of the elastic plate and the rotating seat 2 to connect the elastic plate and the rotating seat 2;

[0091] Step S60: Place a number of balls 5 on the bottom plate 15 , and then connect the bottom plate 15 to the bottom of the rotating seat 2 through the connecting rod 6 , so that the balls 5 contact the rotating seat 2 .

[0092] The damping device of the island and reef outpost building provided by the present application has multi-directional energy dissipation, can adjust the friction energy dissipation value according to the amplitude, and improve the natural vibration period of the structure. The damping device of the present application is provided with a plurality of linkage rods 4, and the linkage rods 4 have hard springs. Each linkage rod 4 is respectively connected to a different column 9 of the island and reef outpost building, and can consume the external impact energy received by each column 9. The damping device of the present application is provided with a plurality of sliding friction devices 22, and each sliding friction device 22 is respectively matched with the corresponding linkage rod 4 to realize friction energy dissipation. The sliding friction device 22 has a lifting guide groove 221, which improves the seismic resistance of the building structure. By increasing the number of linkage rods 4, the damping device of the present application can be applied to high-rise buildings with hexagonal structures. The semicircular friction plate at the end of the linkage rod 4 can slide along the arc-shaped lifting guide groove 221 on the sliding friction element 22. The end of the linkage rod 4 will rise along the slope while squeezing the top rubber plate. The rubber plate in turn provides greater pressure, increasing the friction of the linkage rod 4. This increases the energy dissipated by sliding friction, improving the energy dissipation capacity of the damping device and facilitating its response to varying vibration amplitudes. The damping device of the present application installs a hard spring or other torque dissipator 7 that dissipates energy through tension at the corner of the rotating seat 2. The torque dissipator 7 is torsionally dissipated through the rotational displacement of the rotating seat 2 and the fixed seat 1, and cooperates with the sliding friction element 22 to achieve multi-directional energy dissipation, thereby reducing the torsional vibration period of the building. The damping device of the present application installs a pressure alarm in the groove 131 of the elastic plate 13 (rubber plate) within the fixed seat 1. When the friction plate at the end of the linkage rod 4 slides a certain distance in the lifting guide groove 221 of the sliding friction element 22, the pressure on the rubber plate increases, triggering the pressure alarm to issue an alarm signal. This application installs a rotating energy dissipator 3 on a rotating base 2. When the rotating base 2 is twisted by the torsion force of the linkage rod 4, it twists, inducing the connecting rod 6 (connecting screw) to squeeze the rotating energy dissipator 3, sounding an alarm and providing a timely warning of excessive natural vibration period of the building. By varying the installation orientation and number of sliding friction devices 22 in the damping device, this application can adapt to most high-rise sentry posts, and installation is convenient and quick, ensuring the normal operation of the building structure during typhoons.
