Description

Technical Field

[0001] The invention belongs to the technical field of building shock-absorbing dampers, in particular to a friction damper for shock absorption in public buildings and an installation method thereof. Background Art

[0002] Energy dissipation and shock absorption of building structures refers to the design and installation of specific structural measures to reduce the impact of the vibration amplitude of the building structure under earthquakes or other vibration loads on the structure. The application of dampers in building structures has enabled people to break away from the traditional concept of strengthening beams, columns and walls to improve vibration resistance. Combined with the dynamic performance of the structure, it cleverly avoids or reduces the damage to buildings caused by earthquakes and wind.

[0003] The existing publication number is CN118958541A, which is a damper device for energy dissipation and shock absorption of building structures. Through the arrangement of ventilation nets and heat-conducting fins and other mechanisms, it is ensured that the heat-conducting fins can absorb friction heat more efficiently to avoid high temperatures that affect the shock absorption effect of the entire equipment. However, when an earthquake causes the entire building to vibrate, the wavelength of the earthquake can be divided into transverse waves and longitudinal waves, that is, the building will vibrate in the vertical and horizontal directions. After the device is installed between the buildings on both sides, it can only effectively buffer the amplitude of the parallel friction plates, while the amplitude of the vertical friction plates will cause lateral bending deformation of both the mounting parts and the friction plates, thereby causing damage to the straight plates inside the device and failing to achieve effective earthquake resistance, so it needs to be improved. Summary of the Invention

[0004] In order to solve the problem that existing dampers are easily bent and deformed due to earthquakes, the present invention adopts a technical solution: a friction damper for shock absorption of public buildings, comprising: Friction resistance components, connecting components and attachment components; The attachment assembly includes: Attachment plates are arranged on both sides of the outer surface of the friction resistance member, and the back of the inner cavity of the attachment plate is evenly provided with heat dissipation grooves; The docking side shell has its outer surface fixedly connected to the side of the attachment plate, and thick spring connecting plates are symmetrically provided on the upper and lower sides of the inner wall of the docking side shell. The attachment plates on both sides are plugged into the side of the counterweight shell through the docking side shell and can slide vertically along the outer surface of the counterweight shell and then reset by the thick spring connecting plates. The friction outer rods are evenly arranged on the outside of the attachment plate, and the outer surfaces of the friction outer rods are fixedly welded to the inner cavity of the attachment plate.

[0005] Furthermore, the friction resistance element includes: The counterweight shell has complementary grooves evenly formed on both sides of its outer surface, the outer surface of the friction outer rod is slidably connected to the outer surface of the counterweight shell through the complementary grooves, the outer surface of the friction outer rod complements the inner wall of the complementary grooves, and the two are fitted together in a nearly bite-fitting manner; Internal temperature sensing components are evenly arranged inside the counterweight shell and are used to measure the temperature of the inner wall of the complementary chute; There are two limiting top plates, and the middle parts of the outer surfaces of the limiting top plates are plugged into the end parts of the friction resistance plates.

[0006] Furthermore, the connection component includes: A cluster shell, wherein the top of the outer surface of the cluster shell is symmetrically provided with embedded connecting rods, and the outer surface of the embedded connecting rods is inserted into the interior of the building; A buffer sleeve, the outer surface of which is fixedly connected to the inner wall of the cluster shell via an expansion groove; A thick connecting rod, the top of which is plugged into the inner wall of the buffer sleeve, and the bottom of the outer surface of the thick connecting rod is sleeved with a limiting inner plate. The thick connecting rods of the connecting components on both sides are symmetrically distributed and respectively connect the buildings on both sides. The thick connecting rod can slide in the inner cavity of the cluster shell, thereby compressing the buffer sleeve, but cannot be pulled out from the inside of the cluster shell.

[0007] Furthermore, the connection component further includes: A fixed outer plate, the inner cavity of the fixed outer plate is evenly provided with guide grooves, the bottom end of the outer surface of the coarse connecting rod is slidingly connected to the inner wall of the fixed outer plate through the guide groove, the outer surface of the limiting inner plate is slidingly connected to the inner wall of the fixed outer plate, and the side of the outer surface of the fixed outer plate away from the coarse connecting rod is fixedly connected to the outer surface of the counterweight shell. When the coarse connecting rod tends to slide out of the cluster shell, it will drive the limiting inner plate to slide along the inner wall of the fixed outer plate, and at the same time pull the attached plate to slide vertically along the outer surface of the counterweight shell.

[0008] Furthermore, the connection component further includes: A built-in motor, wherein the outer surface of the built-in motor is fixedly connected to the inner wall of the friction outer rod; A vertical fan blade rod, wherein the axis of the inner cavity of the vertical fan blade rod is plugged into the outer surface of the built-in motor shaft, and the outer surface of the vertical fan blade rod is rotatably connected to the inner wall of the friction outer rod; An extended wire, one end of which is fixedly connected to the inner cavity of the built-in motor, and the other end of which is connected to the inner cavity of the fixed outer plate through a heat dissipation groove.

[0009] Furthermore, the internal temperature sensing component includes: A deflection plate, the outer surface of which is rotatably connected to the inner wall of the counterweight shell via a guide rod, and the outer surface of the guide rod is fixedly connected to the inner wall of the counterweight shell. Since a return spring is provided in the inner cavity of the guide rod, under normal circumstances, the deflection plate will deflect to the side that abuts the inner wall of the counterweight shell, i.e., the location of the complementary slide groove, due to the elasticity of the return spring; The temperature sensing plate, the outer surface of the temperature sensing plate is fixedly connected to the inner cavity of the deflection plate, and the side of the outer surface of the temperature sensing plate away from the deflection plate is squeezed against the inner wall of the counterweight shell through a complementary sliding groove.

[0010] Furthermore, the internal temperature sensing component further includes: A traction drum, the outer surface of which is fixedly connected to the inner wall of the counterweight shell; A storage drum, wherein the outer surface of the storage drum is plugged into the axis center of the outer surface of the traction drum, and the outer surface of the traction drum shaft extends through the through opening to the axis center of the inner wall of the storage drum; The traction belt, one end of which extends to the outside of the storage drum through a groove and is plugged into the outer surface of the deflection turn plate, the other end of which is fixedly connected to the outer surface of the traction drum shaft, and the shaft of the traction drum drives the end part of the traction belt to rotate, thereby achieving the effect of winding the traction belt and pulling the deflection turn plate to rotate.

[0011] Furthermore, the limiting top plate also includes: An expanded shell, wherein an expansion opening is formed at the axis center of the top of the inner cavity of the expanded shell; An embedded slide, wherein the inner wall of the embedded slide is slidably connected to the top of the outer surface of the flared shell through the expansion opening, and the inner wall of the embedded slide is evenly provided with buffer spring strips; The drainage heat sink has an outer surface fixedly connected to the inner wall of the flared shell, and connecting rods are evenly arranged on the top of the inner cavity of the drainage heat sink, and the connecting rods extend to the inside of the counterweight shell, and the bottom of the drainage heat sink extends to the outside of the flared shell through the air inlet groove.

[0012] The beneficial effects of the present invention are as follows: 1. The device can connect public buildings on both sides, absorb the vibration force of the building and convert it into friction internal energy between the friction outer rod and the complementary slide groove, thereby achieving a buffering and shock-absorbing effect and enhancing the stability of the building. Since the vibration direction of the building may not be in the same plane as the thick connecting rod, it is possible to cause the thick connecting rod to bend laterally. The device is improved at the position of the connection point with the building so that the embedded connecting rod can slide relative to the inner wall of the cluster shell, thereby reducing the bending stress of the thick connecting rod by side-pressure buffer sleeve, avoiding bending deformation of the friction resistance component and the thick connecting rod, which may lead to damage to the device.

[0013] 2. Due to the strong friction between the friction outer rod and the complementary slide, high temperature will be generated at the contact point between the two, and cooling work is required. The friction outer rod is cooled from the inside out by the vertical fan blade rod, and the inner wall of the complementary slide is cooled by the drainage heat dissipation plate. This can effectively alleviate the problem of thermal deformation of the friction outer rod and the complementary slide caused by continuous high temperature. Both adopt an inside-out heat dissipation method to avoid air circulation on the contact surface of the friction outer rod and the complementary slide, causing external impurities to adhere to the outer surface of the complementary slide and the friction outer rod, causing the friction resistance to get stuck.

[0014] 3. Only when the friction resistance is overheated inside, the corresponding heat dissipation equipment can be started to effectively dissipate heat. Under normal circumstances, the temperature sensing plate is used to contact the inner wall of the complementary chute to monitor the actual temperature of the inner wall of the chute. When the temperature is too high, not only can the temperature sensing plate be pulled open by starting the traction drum to avoid the problem of continuous heat absorption and damage to the temperature sensing plate, but the inner wall of the complementary chute will no longer be blocked by the deflection plate, which is more conducive to heat dissipation. At the same time, the temperature sensing triggering method is also conducive to reducing the energy consumption of power heat dissipation equipment such as the drainage heat sink.

[0015] 4. In the actual process of connecting the buildings on both sides, since the flared shells on both sides do not contact any buildings, when the flared shells on both sides are subjected to impact due to wind and rain, the flared shells will slide relative to the embedded slide plates at the fixed points under the action of the buffer spring belt, thereby reducing the external force on the device and improving the stability of the device and the connection stability between the embedded connecting rod and the building.

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0019] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a friction damper for shock absorption of public buildings, comprising: Friction resistance component 1, connecting component 2 and attaching component 3; The attachment component 3 includes: The attachment plates 31 are arranged on both sides of the outer surface of the friction resistance member 1, and the back of the inner cavity of the attachment plates 31 is evenly provided with heat dissipation grooves 35; The docking side shell 33 has its outer surface fixedly connected to the side of the attachment plate 31, and thick spring connecting plates 34 are symmetrically provided on the upper and lower sides of the inner wall of the docking side shell 33. The attachment plates 31 on both sides are plugged into the side of the counterweight shell 11 through the docking side shell 33, and can slide vertically along the outer surface of the counterweight shell 11 and then return to their original position through the thick spring connecting plates 34. The friction outer rods 32 are evenly arranged outside the attachment plate 31 , and the outer surfaces of the friction outer rods 32 are fixedly welded to the inner cavity of the attachment plate 31 .

[0020] The friction resistance member 1 includes: The counterweight shell 11 has complementary grooves 13 evenly formed on both sides of the outer surface thereof. The outer surface of the friction outer rod 32 is slidably connected to the outer surface of the counterweight shell 11 through the complementary grooves 13. The outer surface of the friction outer rod 32 is complementary to the inner wall of the complementary grooves 13, and the two are fitted together in a nearly bite-fitting manner. The internal temperature sensing component 4 is evenly arranged inside the counterweight shell 11 and is used to measure the temperature of the inner wall of the complementary chute 13; The limiting top plates 12 are two in number, and the middle portion of the outer surface of the limiting top plates 12 is plugged into the end portion of the friction resistance plate.

[0021] Connectivity component 2 includes: The cluster shell 21 has an embedded connecting rod 22 symmetrically arranged on the top of the outer surface of the cluster shell 21, and the outer surface of the embedded connecting rod 22 is inserted into the interior of the building; The buffer sleeve 23 has an outer surface fixedly connected to the inner wall of the cluster shell 21 through an expansion groove; The top of the thick connecting rod 24 is inserted into the inner wall of the buffer sleeve 23, and the bottom of the outer surface of the thick connecting rod 24 is sleeved with the limiting inner plate 25. The thick connecting rods 24 of the connecting components 2 on both sides are symmetrically distributed and respectively connect the buildings on both sides. The thick connecting rod 24 can slide in the inner cavity of the cluster shell 21, thereby compressing the buffer sleeve 23, but cannot be pulled out from the inside of the cluster shell 21.

[0022] The connection components also include: The fixed outer plate 26 has guide grooves 27 evenly arranged in the inner cavity of the fixed outer plate 26. The bottom end of the outer surface of the coarse connecting rod 24 is slidably connected to the inner wall of the fixed outer plate 26 through the guide grooves 27. The outer surface of the limiting inner plate 25 is slidably connected to the inner wall of the fixed outer plate 26. The side of the outer surface of the fixed outer plate 26 away from the coarse connecting rod 24 is fixedly connected to the outer surface of the counterweight shell 11. When the coarse connecting rod 24 tends to slide out of the cluster shell 21, it will drive the limiting inner plate 25 to slide along the inner wall of the fixed outer plate 26, and at the same time pull the attachment plate 31 to slide vertically along the outer surface of the counterweight shell 11.

[0023] The connecting components 2 on both sides of the device are connected to the buildings on both sides respectively, that is, the embedded connecting rods 22 are deeply buried inside the buildings to complete the connection work.

[0024] When a building is in an earthquake, the buildings on both sides will pull the cluster shell 21 to the sides due to vibration. At this time, the cluster shell 21 drives the thick connecting rod 24 to move, thereby pulling the attachment plate 31 to slide along the outer surface of the counterweight shell 11. Since the friction outer rod 32 is arranged inside the complementary slide groove 13, and the attachment plate 31 can only slide along the outer surface of the counterweight shell 11 under the restriction of the fixed outer plate 26, the friction outer rod 32 will slide along the inner wall of the complementary slide groove 13, thereby generating a strong friction effect. The friction force is used to generate high temperature and convert the vibration force into internal energy, thereby playing a buffering effect and stabilizing the buildings connected on both sides.

[0025] Since the vibration direction of the building may not be in the same plane as the thick connecting rod 24, it is possible that the thick connecting rod 24 will tend to bend sideways. At this time, the building will drive the cluster shell 21 to slide sideways, but the thick connecting rod 24 is restricted by the limiting inner plate 25 and cannot bend, so the top end of the thick connecting rod 24 will be squeezed with the buffer sleeve 23, thereby deforming the buffer sleeve 23. At this time, the cluster shell 21, the thick connecting rod 24 and the friction resistance member 1 will slide relative to each other, reducing the adverse effects of bending stress on the device.

[0026] Since the outer surface of the friction outer rod 32 will heat up rapidly when the friction outer rod 32 and the complementary slide groove 13 generate internal energy, it is necessary to cool the friction outer rod 32 in time to avoid thermal deformation of the friction outer rod 32, which may cause the attachment component 3 to detach from the friction resistance part 1. Therefore, a vertical fan blade rod 38 is provided inside each friction outer rod 32, that is, inside the attachment plate 31. The vertical fan blade rod 38 is driven to rotate by the built-in motors 36 on both sides, so that the air flow enters the inner wall of the attachment plate 31 through the heat dissipation groove 35 and circulates out, thereby cooling the friction outer rod 32.

[0027] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: based on embodiment 1, the connection component 2 further includes: A built-in motor 36, the outer surface of the built-in motor 36 is fixedly connected to the inner wall of the friction outer rod 32; The vertical blade rod 38 has an inner axis thereof plugged into the outer surface of the shaft of the built-in motor 36 , and the outer surface of the vertical blade rod 38 is rotatably connected to the inner wall of the friction outer rod 32 ; The extended wire 37 has one end fixedly connected to the inner cavity of the built-in motor 36 , and the other end connected to the inner cavity of the fixed outer plate 26 through the heat dissipation slot 35 .

[0028] The internal temperature sensing component 4 includes: The deflection plate 41 has an outer surface that is rotatably connected to the inner wall of the counterweight shell 11 via a guide rod, and the outer surface of the guide rod is fixedly connected to the inner wall of the counterweight shell 11. Since a return spring is provided in the inner cavity of the guide rod, under normal circumstances, the deflection plate 41 will deflect toward the side that abuts the inner wall of the counterweight shell 11, that is, the location of the complementary slide groove 13, due to the elasticity of the return spring. The outer surface of the temperature sensing plate 42 is fixedly connected to the inner cavity of the deflection plate 41 , and the side of the outer surface of the temperature sensing plate 42 away from the deflection plate 41 is squeezed against the inner wall of the counterweight shell 11 through the complementary sliding groove 13 .

[0029] The internal temperature sensing component 4 also includes: A traction drum 43, the outer surface of which is fixedly connected to the inner wall of the counterweight shell 11; The storage reel 44 has an outer surface that is plugged into the axis of the outer surface of the traction drum 43, and the outer surface of the rotating shaft of the traction drum 43 extends through the through opening to the axis of the inner wall of the storage reel 44; The traction belt 45, one end of the traction belt 45 extends to the outside of the storage reel 44 through the groove and is plugged into the outer surface of the deflection turn plate 41, and the other end of the traction belt 45 is fixedly connected to the outer surface of the rotating shaft of the traction drum 43. The shaft of the traction drum 43 drives the end part of the traction belt 45 to rotate, thereby achieving the effect of winding the traction belt 45 and pulling the deflection turn plate 41 to rotate.

[0030] The limiting top plate 12 also includes: The flared shell 121 has an expansion opening at the axis center of the top of the inner cavity of the flared shell 121; An embedded slide 122, the inner wall of the embedded slide 122 is slidably connected to the top of the outer surface of the expanded shell 121 through the expansion opening, and the inner wall of the embedded slide 122 is evenly provided with buffer spring strips 123; The drainage heat sink 124, the outer surface of the drainage heat sink 124 is fixedly connected to the inner wall of the flared shell 121, the top of the inner cavity of the drainage heat sink 124 is evenly provided with connecting rods 125, and the connecting rods 125 extend to the interior of the counterweight shell 11, and the bottom of the drainage heat sink 124 extends to the outside of the flared shell 121 through the air inlet groove.

[0031] Before the friction outer rod 32 rubs against the complementary chute 13, the deflection plate 41 under the action of the spring rebound force will directly contact the inner wall of the complementary chute 13 through the temperature sensing plate 42. When the inner wall of the complementary chute 13 heats up due to the friction, the temperature sensing plate 42 will trigger the traction drum 43 at the corresponding position through the internal sensor, so that the traction drum 43 will pull the deflection plates 41 on both sides apart by winding the traction belt 45. At this time, the temperature sensing plate 42 is separated from the inner wall of the complementary chute 13 and the lower drainage heat dissipation plate 12 is started. 4. The drainage heat sink 124 dissipates heat from the interior of the counterweight shell 11 through the connecting rod 125. Since the inner wall of the complementary chute 13 is not in contact with the temperature-sensing plate 42 at this time, the actual heat dissipation effect of the complementary chute 13 will be enhanced, thereby dissipating heat quickly. After a period of cooling treatment, the traction drum 43 and the drainage heat sink 124 are simultaneously powered off, and then the deflection rotating plate 41, under the action of the spring rebound force inside the guide rotating rod, presses the temperature-sensing plate 42 against the inner wall of the complementary chute 13 to perform temperature monitoring.

[0032] In the actual process of connecting the buildings on both sides, since the flared shells 121 on both sides do not contact any buildings, when the flared shells 121 on both sides are subjected to impact force due to wind and rain, the flared shells 121 will slide relative to the embedded slide plate 122 at the fixed point under the action of the buffer spring belt 123, thereby reducing the external force on the device and improving the stability of the device and the connection stability of the embedded connecting rod 22 and the building.

[0033] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
