Description

Technical Field

[0001] This invention relates to the field of vibration-proof or shock-resistant building technology, specifically to a shock-proof device for steel structure buildings and a steel structure building. Background Technology

[0002] Steel structure houses are gradually gaining popularity. Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of beams, columns, and trusses made of steel sections and plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. Because they can be assembled on-site anytime and anywhere, the assembly process is convenient and quick, and they are relatively lightweight and easy to construct, making them widely used in outdoor settings.

[0003] Steel structure buildings are now widely used in large factories, stadiums, and high-rise buildings. Earthquakes are one of the natural disasters that threaten human life and property. In earthquake-prone areas, earthquake resistance is a crucial measure to protect life and property when constructing steel structure factories. Currently, most steel structure buildings are earthquake-resistant through reinforcement or the addition of simple damping structures. Reinforcement alone results in poor earthquake resistance; the impact of an earthquake can easily damage the steel structure. Existing technologies often involve adding springs or other elastic components to the joints of the steel structure to mitigate earthquake impacts to some extent, such as adding springs to the base of the steel structure. However, during an earthquake, the impact force acts throughout the entire steel structure. Relying solely on the elasticity of these components to resist earthquakes, and increasing the number and coverage of these components, can negatively impact the stability of the steel structure itself. Summary of the Invention

[0004] In view of the technical problem that the earthquake resistance of steel structure buildings is poor in the existing technology, the present invention provides an earthquake resistance device and a steel structure building for steel structure buildings, which has a multi-level buffer structure, which is beneficial to buffering the impact of earthquakes on buildings and protecting human life and property safety.

[0005] On one hand, the present invention provides a shock-absorbing device for steel structure buildings, including a damping rod and a first abutment assembly. The damping rod includes a first elastic element, one end of which is connected to a sleeve, and the other end of which is connected to a connecting rod, one end of which is sleeved inside the sleeve. The first abutment assembly includes an inclined plate and a top plate. One end of the inclined plate is provided with an inclined surface, and the other end of the inclined plate is connected to a telescopic rod through a second elastic element. The top plate is fitted with a guide frame fixed to the steel structure building. One end of the top plate is in contact with the inclined surface, and the other end of the top plate is hinged to a first support plate, which is also hinged to the damping rod.

[0006] Furthermore, there are two first abutment components, which are located on the upper and lower sides of the damping rod, respectively.

[0007] Furthermore, the first elastic element is a spring, and a sealing plug plate matching the shape of the sleeve is provided at the end of the connecting rod facing the sleeve.

[0008] Furthermore, the end of the sleeve facing away from the connecting rod is provided with multiple air holes that penetrate the sleeve's arm.

[0009] Furthermore, it also includes a second abutment assembly, which includes a first clamping plate, a second clamping plate, and two earpieces. One end of the first clamping plate and one end of the second clamping plate are connected by a telescopic rod. The other end of the first clamping plate is provided with a first clamping part, and the other end of the second clamping plate is provided with a second clamping part. The first clamping part and the second clamping part are arranged opposite to each other. The two ends of the earpieces are hinged to the first clamping plate and the second clamping plate, respectively. The first clamping plate is provided with a first limiting plate, and the second clamping plate is provided with a second limiting plate. The first limiting plate and the second limiting plate are arranged opposite to each other, and the earpieces are located between the first limiting plate and the second limiting plate. The earpieces are connected to the top plate by a bracket.

[0010] Furthermore, one end of the dual earpieces is connected to the first limiting plate via a second support plate, and both ends of the second support plate are hinged to the dual earpieces and the first limiting plate, respectively; the other end of the dual earpieces is connected to the second limiting plate via a third support plate, and both ends of the third support plate are hinged to the dual earpieces and the second limiting plate, respectively.

[0011] Furthermore, the second abutment assembly also includes fasteners for connecting the first or second clamping plate to the steel structure building.

[0012] Furthermore, a rubber pad is fixedly connected to the end of the connecting rod facing away from the sleeve; or, a rubber pad is fixedly connected to the end of the sleeve facing away from the connecting rod.

[0013] On the other hand, the present invention provides a steel structure building, including a square frame unit composed of steel frames, wherein the frame unit is provided with a shock-absorbing device, and the two ends of the damping rod are respectively hinged to the frame unit and the damping rod is arranged along the diagonal of the frame unit.

[0014] Furthermore, the steel frame is provided with a groove for accommodating the second elastic element and the telescopic rod. The end of the telescopic rod facing away from the inclined panel abuts against the inner wall of one end of the groove, and the end of the inclined panel facing away from the top plate is placed in the groove.

[0015] The beneficial effects of this invention are as follows:

[0016] With a multi-level buffer and earthquake-resistant structure, it can buffer the lateral and longitudinal impacts of earthquakes to a certain extent, making steel structure buildings with earthquake-resistant devices have good earthquake resistance and protecting human life and property safety.

[0017] The damping rod, through the cooperation of a rubber stopper and a sleeve, slows down the retraction speed of the damper, preventing secondary vibrations and providing a buffering and shock-absorbing effect. The damping rod, in conjunction with the first abutment assembly, provides two-stage buffering of seismic impact forces. The movement of the damping rod drives the movement of multiple first abutment assemblies, compressing the second elastic element and the telescopic rod, thus providing specific localized buffering and shock absorption for steel structure buildings.

[0018] By setting up a third damping component in conjunction with the damping rod and the first damping component, a three-level buffer and seismic protection system is formed. The first and second clamping parts in the third damping component tightly clamp the steel structure building locally, which is beneficial for buffering the impact of earthquakes on the building.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0030] like Figure 1As shown, one embodiment of the present invention provides a shock-absorbing device for steel structure buildings, including a damping rod 1 and a first abutment assembly 2. The damping rod 1 includes a first elastic element 11, one end of which is connected to a sleeve 12, and the other end of which is connected to a connecting rod 13. One end of the connecting rod 13 is sleeved inside the sleeve 12. The first abutment assembly 2 includes an inclined plate 21 and a top plate 22. One end of the inclined plate 21 is provided with an inclined surface, and the other end of the inclined plate 21 is connected to a telescopic rod 24 through a second elastic element 23. The top plate 22 is covered with a guide frame 26 fixed to the steel structure building. One end of the top plate 22 is in contact with the inclined surface, and the other end of the top plate 22 is hinged to a support plate, which is also hinged to the damping rod 1. In this embodiment, when the steel structure building is subjected to seismic impact and shakes, the seismic impact force first passes through the damping rod 1, causing the damping rod 1 to perform overall telescopic movement to buffer the vibration frequency and amplitude. During the telescopic movement of one section of the damping rod 1, the connecting rod 13 and the first elastic element 11 are stretched, causing the first elastic element 11 to deform and play a buffering role. At the same time, when the damping rod 1 telescopically moves, it will drive the first abutment assembly 2 connected to the damping rod 1 to function; the damping rod 1 causes the bracket 38 to shift, and the guide frame 26 is fixed in the steel structure building, thereby causing the top plate 22 to move up and down along the guide frame 26. The movement of the top plate 22 drives the inclined plate 21 to move horizontally through the inclined surface, thereby squeezing the second elastic element 23 and the telescopic rod 24. The elastic telescopic force of the second elastic element 23 can provide specific buffering and earthquake protection for local areas of the steel structure building.

[0031] In embodiments of the present invention, the connecting rod 13 and the sleeve 12 are used as a set. The damping rod 1 can have one set, or two or more sets, to enhance the buffering and shock absorption effect. In embodiments of the present invention, the inclined panel 21 is provided with an inclined surface that contacts the top plate 22. When the top plate 22 moves, it pushes the inclined panel 21, converting the vertical movement of the top plate 22 into the horizontal movement of the inclined panel 21. The inclined surface faces away from the extension direction of the telescopic rod 24 and the second elastic member 23, so that when the inclined panel 21 moves in the horizontal direction, it pushes the telescopic rod 24 to abut against the steel building structure, compressing the second elastic member 23, thereby achieving a buffering and shock absorption effect.

[0032] In embodiments of the present invention, the first support plate 25 is hinged to the connecting rod 13; or, the first support plate 25 is hinged to the sleeve 12.

[0033] like Figure 3As shown, in one embodiment of the present invention, the first elastic element 11 is a spring, and a sealing plug plate 14 matching the shape of the sleeve 12 is provided at one end of the connecting rod 13 facing the sleeve 12. When an earthquake occurs, the earthquake impact force first passes through the damping rod 1, and the damping rod 1 performs overall extension and contraction to buffer the impact. The extension and contraction of the connecting rod 13 within the sleeve 12 plays a buffering role, reducing the vibration frequency and amplitude. During the extension and contraction process, the sealing plug plate 14 and the first elastic element 11 are stretched, causing the first elastic element 11 to deform. When the damper retracts, it drives the sealing plug plate 14 to compress gas within the sleeve 12, forming air pressure. This slows down the retraction speed of the connecting rod 13, preventing secondary vibration. When it extends, it drives the sealing plug plate 14, generating low air pressure within the sleeve 12, slowing down the extension speed of the connecting rod 13, preventing secondary vibration, thereby achieving a buffering and shock absorption effect. In a preferred embodiment of the present invention, the end of the sleeve 12 facing away from the connecting rod 13 is provided with a plurality of air holes 15 penetrating the sleeve 12. During an earthquake, due to the large impact force, the connecting rod 13 moves very quickly within the sleeve 12. When the sealing plug 14 moves within the sleeve 12, the compressed gas moves quickly, resulting in a small exhaust volume from the air holes 15. When the sealing plug 14 reciprocates within the sleeve 12, the changes in gas volume and pressure during gas compression and extraction buffer the movement of the connecting rod 13. Simultaneously, gas can be discharged or replenished through the air holes 15. The displacement range for better buffering effect during the movement of the connecting rod 13 and the sealing plug 14 within the sleeve 12 is larger, resulting in a better buffering and shock absorption effect. In this embodiment, the sealing plug 14 can be a rubber plug, a plastic plug, a metal plug, etc. In embodiments of the present invention, the first elastic element 11 can also be a rubber pad 16, an elastic support, an air cushion, etc.; the second elastic element 23 can be a spring, an air cushion, a rubber pad 16, etc.

[0034] In a preferred embodiment of the present invention, there are two first abutment components 2, located on opposite sides of the damping rod 1 in the plane of the damping rod 1. After the damping rod 1 is installed in the steel structure building, the two abutment components can be located on the upper and lower sides or the left and right sides of the damping rod 1. The two damping rods 1 are fixed in different steel frames, enhancing the overall protection of the steel structure building. In embodiments of the present invention, the number of second abutment components 3 can also be one, three, four, etc.

[0035] like Figures 2-5As shown, one embodiment of the present invention provides a shock-absorbing device for steel structure buildings, including a damping rod 1 and a first abutment assembly 2. The shock-absorbing device also includes a second abutment assembly 3, which includes a first clamping plate 31, a second clamping plate 32, and a double earpiece 39. One end of the first clamping plate 31 and one end of the second clamping plate 32 are connected by a telescopic sleeve 33. The other end of the first clamping plate 31 is provided with a first clamping part 34, and the other end of the second clamping plate 32 is provided with a second clamping part 35. The first clamping part 34 and the second clamping part 35 are arranged opposite to each other. The two ends of the double earpiece 39 are hinged to the first clamping plate 31 and the second clamping plate 32, respectively. The first clamping plate 31 is provided with a first limiting plate 36, and the second clamping plate 32 is provided with a second limiting plate 37. The first limiting plate 36 and the second limiting plate 37 are arranged opposite to each other, and the double earpiece 39 is located between the first limiting plate 36 and the second limiting plate 37. The double earpiece 39 is connected to the top plate 22 by a bracket 38. In this embodiment, the damping rod 1, the second elastic element 23, and the telescopic rod 24 play corresponding roles in providing buffer protection for the steel structure building. Simultaneously, the movement of the top plate 22 drives the support 38 to move synchronously, which in turn drives the double earpieces 39 to move synchronously. During the movement of the double earpieces 39, they contact the first limiting plate 36 or the second limiting plate 37 and push the first limiting plate 36 or the second limiting plate 37 to move, causing the first clamping plate 31 and the second clamping plate 32 to move towards each other, tightly clamping the steel structure building locally. Combined with the damping rod 1 and the first transition assembly, this forms a multi-layered buffer and seismic resistance, which is beneficial for buffering the impact of earthquakes on the building. In one embodiment of the present invention, the support 38 is a long U-shape, with both ends of the support 38 fixedly connected to the top plate 22 and the double earpieces 39, respectively. The connecting rod 13 has sufficient length to allow the second transition assembly 3 to clamp the steel structure building. In this embodiment, the second abutment component 3 is fixed to the steel structure building. One fixing method is to set up a receiving bracket 38 in the steel structure building and place the second abutment component 3 on the receiving bracket 38. In a preferred embodiment, the first clamping plate 31 and the second clamping plate 32 in the second abutment component 3 are hinged to the receiving bracket 38 through a fourth support plate. When the bracket 38 pushes the double earpiece 39 to move, the first clamping plate 31 or the second clamping plate 32 can rotate around the hinged end that is hinged to the fourth support plate. One fixing method will not affect the movement of the first clamping plate 31 or the second clamping plate 32; another fixing method is that the two ends of the double earpieces 39 are hinged to the first clamping plate 31 and the second clamping plate 32 through a rotating shaft. The rotating shaft is integrally formed or welded with a fixing rod 43. The fixing rod 43 is fixed to the steel structure bracket 38. When the double earpieces 39, the first clamping plate 31, and the second clamping plate 32 move, the rotating shaft only has a circular rotation movement, which will not affect the movement of the double earpieces 39, the first clamping plate 31, and the second clamping plate 32.

[0036] like Figure 6As shown, in a preferred embodiment, the double earpiece 39 includes a slide rod 392 and a double earpiece sleeve 391. The double earpiece sleeve 391 is sleeved on the slide rod 392. The double earpiece sleeve 391 is connected to the top plate 22 through a bracket 38. One end of the double earpiece sleeve 391 is connected to the first limiting plate 36 through a second support plate 361. The two ends of the second support plate 361 are respectively hinged to the double earpiece sleeve 391 and the first limiting plate 36. The other end of the double earpiece sleeve 391 is connected to the second limiting plate 37 through a third support plate 371. The two ends of the third support plate 371 are respectively hinged to the double earpiece sleeve 391 and the second limiting plate 37. In this embodiment, the movement of the top plate 22 simultaneously moves the support 38, thereby causing the double-ear sleeve 391 to move up and down along the slide rod 392. In the initial position, i.e., the installation position before an earthquake, the axes of the second support plate 361 and the third support plate 371 are parallel to the axes of the first limiting plate 36 and the second limiting plate 37. At this time, the second support plate 361 and the third support plate 371 are horizontally positioned, and the horizontal distance between the first limiting plate 36, the second limiting plate 37, and the double-ear sleeve 391 is... The second support plate 361 and the third support plate 371 are the longest and the distance between them is the longest. When the double-eared sleeve 391 moves up and down along the sliding rod 392, it drives the first limiting plate 36 and the second limiting plate 37 to move towards each other. The horizontal distance between the first limiting plate 36, the second limiting plate 37 and the double-eared sleeve 391 becomes smaller, thereby causing the telescopic sleeve 33 to retract. The first clamping part 34 and the second clamping part 35 move towards each other, tightly clamping the part of the steel structure building, improving the stability of the steel structure building, and playing a buffering and earthquake-resistant role. Figure 6 The double-ear sleeve 391 moves upward to bring the first clamping part 34 and the second clamping part 35 closer together for clamping. In this embodiment, the second abutment assembly 3 also includes fasteners connecting the first clamping plate 31 or the second clamping plate 32 to the steel structure building. The second abutment assembly 3 is fixed to the steel structure building. A crossbar 42 connects the first clamping plate 31 to the steel structure building and the second clamping plate 32 to the steel structure building. It is also necessary to enable the first clamping plate 31 and the second clamping plate 32 to move in the horizontal direction. A guide hole is opened in the steel structure building to allow the crossbar 42 to move in the horizontal direction. The steel structure building fixes the second abutment assembly 3 in the vertical direction and has a small distance displacement space in the horizontal direction. The length of the guide hole is slightly greater than or equal to the distance between the first clamping part 34 or the second clamping part 35 and the part of the steel structure building to be clamped. It should be noted that in this embodiment, the horizontal and vertical directions refer to the directions in which the shock-absorbing device is installed in the steel structure building. In addition, the horizontal and vertical directions should include a range that deviates slightly from the positive horizontal and positive vertical directions.

[0037] like Figure 6As shown, in one embodiment of the present invention, the first clamping plate 31 includes an F-type bracket 38 and a T-type clamping plate, the T-type clamping plate being fixedly connected to the F-type bracket 38; the second clamping plate 32 includes an F-type bracket 38 and a T-type clamping plate, the T-type clamping plate being fixedly connected to the F-type bracket 38; one end of each of the two F-type brackets 38 is movably connected via a telescopic sleeve 33; a double-eared sleeve 391 is located between the two F-type brackets 38; both ends of the double-eared sleeve 391 are hinged to the F-type brackets 38 via a second support plate 361 and a third support plate 371, respectively; when the double-eared sleeve 391 moves up and down, it drives the two F-type brackets 38 to move towards each other, causing the two T-type clamping plates to approach each other and tightly clamp the part of the steel structure building.

[0038] In one embodiment of the present invention, a rubber pad 16 is fixedly connected to one end of the connecting rod 13 facing away from the sleeve 12; or, a rubber pad 16 is fixedly connected to one end of the sleeve 12 facing away from the connecting rod 13, and the rubber pad 16 is fixedly connected to the steel structure building. During an earthquake, the rubber pad 16 plays a role in buffering and shock absorption.

[0039] like Figure 7 and Figure 8 As shown, an embodiment of the present invention also provides a steel structure building, including multiple square frame units 4 composed of steel frames. The two ends of a damping rod 1 are respectively hinged to the frame unit 4, and the damping rod 1 is arranged along the diagonal of the frame unit 4. In one embodiment of the present invention, the frame unit 4 includes an upper steel frame, a lower steel frame, a left steel frame, and a right steel frame. The two ends of the damping rod 1 are respectively hinged to the upper and lower steel frames. The upper and lower steel frames have T-shaped grooves 41. A telescopic rod 24 and a second elastic element 23 are located within the T-shaped groove 41. One end of the telescopic rod 24 abuts against the inner wall of the narrower end of the T-shaped groove 41. The wider end of the T-shaped groove 41 accommodates the end of the inclined panel 21 facing away from the top plate 22. The T-shaped groove 41 restricts the inclined panel 21 to move only along the T-shaped groove 41. In the horizontal direction, the direction of the inclined surface of the inclined panel 21 is opposite to the direction of the telescopic rod 24 facing away from the inclined panel 21. A guide frame 26 is fixed to the upper and lower steel frames by bolts or welding.

[0040] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, the present invention is not limited thereto. Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be covered within the protection scope of the present invention.
