Description

Technical Field

[0001] The present invention belongs to the technical field of wind-resistant supports and assembly and installation methods, and in particular relates to a resettable wind-resistant support and an assembly and installation method for the support. Background Art

[0002] With the rapid development of my country's social economy, the rapid advancement of urban and rural integration, and the extremely serious loss of life and property caused by strong earthquakes such as the Wenchuan earthquake and the Ya'an earthquake in recent years, all sectors of society have unprecedentedly improved their awareness of the seismic safety level of buildings. As a scientific and effective advanced technology for building seismic isolation, building seismic isolation technology has been increasingly used in construction projects such as schools, hospitals, emergency rescue centers and high-rise residential buildings in earthquake-stricken areas in my country.

[0003] Rubber isolation bearings are a commonly used isolation device in building isolation projects. When used in high-intensity earthquake zones, especially high-rise buildings, they are susceptible to tension due to the overturning moment of the superstructure. While rubber isolation bearings currently play a significant role in building seismic resistance and vibration reduction, they also face challenges. As building height increases, they are increasingly affected by wind loads. These wind loads repeatedly squeeze and pull on the rubber isolation bearings. While wind loads are typically far less than the impact on buildings during earthquakes, they are extremely frequent. This high-frequency, repeated squeezing and pulling of the rubber isolation bearings accelerates their aging, significantly reducing their service life. Furthermore, they can easily form defects such as pores within the rubber isolation bearings, seriously impacting their reliability.

[0004] In order to solve the above problems, some wind-resistant bearings are used on buildings. The existing wind-resistant bearings include an upper bearing plate assembly and a lower bearing plate assembly. A shear pin is provided below the upper bearing plate assembly. When there is no earthquake, when the building is subjected to wind loads, the shear pins prevent the building from shaking, thus avoiding high-frequency wind loads from repeatedly squeezing and pulling the isolation rubber bearings, reducing the aging rate of the isolation rubber bearings, and greatly extending the service life of the isolation rubber bearings. On the other hand, defects such as air holes will not be formed inside the isolation rubber, thereby improving the reliability of the isolation rubber bearings. When an earthquake occurs, the shear pins are cut off, and the seismic energy is consumed by the rubber bearings. However, the above-mentioned wind-resistant bearings have the following defects:

[0005] First, when there is no earthquake, high-frequency wind loads repeatedly act on the shear pins, causing them to bend multiple times at the shear grooves. This greatly reduces the shear strength of the shear grooves and shortens their service life. In the event that the shear strength is not reached, the shear pins are sheared off.

[0006] Secondly, in the event of an earthquake, the shear pins are sheared off, and the two cross sections of the shear pins are interlaced. At this time, if horizontal displacement occurs between the upper and lower bearing plates, the two cross sections of the shear pins will interfere with each other, causing damage to the entire bearing;

[0007] Third, it is difficult to install and replace. If the shear pin is cut off due to an earthquake or other external forces, it is even more difficult to replace the shear pin alone. Summary of the Invention

[0013] The second technical problem to be solved by the present invention is to provide an assembly and installation method of the above-mentioned resettable wind-resistant support.

[0014] In order to solve the above problems, the technical solution adopted by the assembly and installation method of the resettable wind-resistant support of the present invention is as follows: the method comprises the following steps:

[0033] Compared with the prior art, the repositionable wind-resistant support and the assembly and installation method of the support provided by the present invention have the following advantages:

[0034] The cam assembly includes an upper support plate assembly and a lower support plate assembly, a shear pin is provided below the upper support plate assembly, a sinking assembly is provided below the shear pin, a return spring assembly is provided on the outside of the sinking assembly, the return spring assembly is located in the lower support plate assembly, and a temporary connection mechanism is provided between the upper support plate assembly and the lower support plate assembly; the upper support plate assembly includes an upper support plate, a shear pin positioning ball panel with a spherical convex surface below is provided below the upper support plate, the shear pin positioning ball panel is connected to the upper support plate by connecting bolts, and a leveling bolt is provided on the lower surface of the upper support plate; The upper surface of the plate is provided with a shear pin groove, and the shear pin is located in the shear pin groove, and the shear pin is fixed to the shear pin positioning ball panel by fastening bolts, and the shear pin includes an upper shear pin, a shearing annular groove and a lower shear pin; the sinking assembly includes a gravity sinking part, a shear pin fastening ball panel, and the gravity sinking part includes a connecting plate located at the top, a cylindrical limiting column located at the bottom and a connecting neck located between the connecting plate and the limiting column, an annular notch is provided on the lower surface of the limiting column, and a shear pin threaded hole is provided in the middle position of the shear pin fastening ball panel, and the lower shear pin is inserted into the shear pin threaded hole, and the connecting plate and the shear pin are fastened. The fixed ball panel is connected by fastening bolts; the lower support plate assembly includes a box bottom frame, a box cover with a circular hole in the middle is arranged above the box bottom frame, an annular stainless steel upper plate is arranged outside the circular hole position on the lower end face of the box cover, and an annular stainless steel lower plate is arranged at the bottom of the box bottom frame at a position corresponding to the annular stainless steel upper plate; the reset spring assembly includes four groups of leaf springs corresponding to the four sides of the box bottom frame, a circular bushing located in the center, a spring washer is arranged between the leaf spring and the circular bushing, the circular bushing, the spring washer and the leaf spring are connected by spring fastening bolts, and the circular bushing is arranged above and below the circular bushing. The two surfaces are inlaid with circular slides, and the limiting column is inserted into the circular bushing; there is a certain distance between the lower surface of the connecting plate and the box cover, a certain distance between the lower end surface of the limiting column and the upper surface of the bottom plate of the box bottom frame, a certain distance between the inner wall surface of the circular hole of the box cover and the connecting neck, and the two ends of the steel leaf spring are attached to the inner wall surface of the side plate of the box bottom frame; the temporary connection mechanism includes a temporary connecting rod located on the side of the upper support plate and the box bottom frame, the upper end of the temporary connecting rod is connected to the upper support plate by an upper connecting bolt, and the lower end of the temporary connecting rod is connected to the box bottom frame by a lower connecting bolt.

[0035] Advantage 1: When the above-mentioned resettable sunken wind-resistant bearing is used and set at the isolation layer, the upper and lower piers of the isolation layer are rigidly connected. By controlling the strength limit value, the working state of the isolation rubber bearing is controlled. That is, when the force applied by the upper and lower piers of the isolation layer to the resettable sunken wind-resistant bearing is less than the strength limit, the shear pin does not break, and the position between the upper and lower piers of the isolation layer does not change significantly, thereby ensuring that the isolation rubber bearing is not affected. This method greatly improves the wind resistance of the building. When there is no earthquake or other large external force, when the support is subjected to wind load, the upper support plate transmits the horizontal force to the limit column of the gravity sinking member through the shear pin, and the limit column transmits the force to the circular bushing and the leaf spring. Because the two ends of the leaf spring are attached to the inner wall surface of the side plate of the bottom frame of the box body, when the circular bushing is forced to move, the leaf spring is compressed. After the wind load is removed, the compressed leaf spring returns to its original shape under its own elastic force. At this time, it will not cause bending fatigue to the shear pin, thereby improving the service life of the shear pin.

[0036] Advantage 2: In the event of a large external force such as an earthquake, the shear pin is sheared off from the shear annular groove, the upper shear pin is connected to the upper support plate, the sunken component falls under its own gravity, the limit column slides down in the circular bushing, and the lower end of the limit column falls to the bottom of the bottom frame of the box body. During the sinking process of the sunken component, the lower shear pin is driven to sink, so that the lower end surface of the upper shear pin is separated from the upper end surface of the lower shear pin by a distance. When horizontal displacement occurs between the resettable wind-resistant bearing and the upper and lower support plates of the bearing, the cross-section of the shear pin does not contact, thereby avoiding damage to the resettable wind-resistant bearing and other parts of the bearing except the shear pin caused by the earthquake. After the earthquake, the shear pin can be replaced, and the rubber isolation system enters the isolation working state. This method greatly improves the service life of the isolation rubber bearing and also improves the reliability of the isolation rubber bearing.

[0037] Advantage 3: The shear pin positioning ball panel and the shear pin fastening ball panel of the resettable sunken wind-resistant bearing adopt a spherical structure, which is convenient for the leveling function of the leveling bolt and can effectively avoid the component space limitation of the resettable sunken wind-resistant bearing after the shear pin body is cut off;

[0038] Advantage 4: Since the leveling bolt support column is provided on the upper surface of the connecting plate at a position corresponding to the leveling bolt, adjustment is more convenient;

[0039] Advantage 5: Since the limiting post and the circular bushing are clearance-fitted, silicone grease or toner is provided between the limiting post and the circular bushing, thereby reducing the resistance between the limiting post and the circular bushing. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 7 As shown, the sinking assembly 4 includes a gravity sinking member 41 and a shear pin fastening ball panel 42. The gravity sinking member 41 includes a connecting plate 411 located at the top, a cylindrical limiting column 412 located at the bottom, and a connecting neck 413 located between the connecting plate 411 and the limiting column 412. An annular notch 414 is provided on the lower surface of the limiting column 412. A shear pin threaded hole 421 is provided in the middle of the shear pin fastening ball panel 42. The lower shear pin 33 is inserted into the shear pin threaded hole 421. The connecting plate 411 and the shear pin fastening ball panel 42 are connected by fastening bolts 415. Figure 8 and Figure 9 As shown, the lower support plate assembly 2 includes a box bottom frame 21, a box cover 23 with a circular hole 22 in the middle is arranged above the box bottom frame 21, an annular stainless steel upper plate 24 is arranged outside the circular hole 22 at the lower end surface of the box cover 23, and an annular stainless steel lower plate 25 is arranged at the bottom of the box bottom frame at a position corresponding to the annular stainless steel upper plate 24. Figure 10 and Figure 11 As shown, the return spring assembly 5 includes four groups of leaf springs 51 corresponding to the four sides of the box bottom frame 21, a circular bushing 52 located in the center, a spring pad 53 is provided between the leaf spring 51 and the circular bushing 52, the circular bushing 52, the spring pad 53 and the leaf spring 51 are connected by a spring fastening bolt 54, and circular slides 55 are inlaid on the upper and lower surfaces of the circular bushing 52, and the limiting column 412 is inserted into the circular bushing 52; there is a certain distance between the lower surface of the connecting plate 411 and the box cover 23, The lower end surface of the limiting column 412 is spaced a certain distance from the upper surface of the bottom plate of the box bottom frame 21, and a certain distance is spaced between the inner wall surface of the circular hole of the box cover 23 and the connecting neck 413, and the two ends of the leaf spring 51 are attached to the inner wall surface of the side plate of the box bottom frame; the temporary connection mechanism 6 includes a temporary connecting rod 61 located on the side of the upper support plate 11 and the box bottom frame 21, the upper end of the temporary connecting rod 61 is connected to the upper support plate 11 through the upper connecting bolt 62, and the lower end of the temporary connecting rod 61 is connected to the box bottom frame 21 through the lower connecting bolt 63.

[0053] The above-mentioned resettable sunken wind-resistant bearing has the following advantages:

[0054] Advantage 1: When the above-mentioned resettable sunken wind-resistant bearing is used and set at the isolation layer, the upper and lower piers of the isolation layer are rigidly connected, and the working state of the isolation rubber bearing is controlled by controlling the strength limit value, that is, when the force applied by the upper and lower piers of the isolation layer to the resettable sunken wind-resistant bearing is less than its strength limit, the shear pin 3 does not break, and the position between the upper and lower piers of the isolation layer does not change significantly, thereby ensuring that the isolation rubber bearing is not affected. This method greatly improves the wind resistance of the building; in the absence of earthquakes or other When a large external force acts, and the pier above the support is subjected to wind load, the upper support plate 11 transmits the horizontal force to the limit column 412 of the gravity sinking member through the shear pin 3, and the limit column 412 transmits the force to the circular bushing 52 and the leaf spring 51. Because the two ends of the leaf spring 51 are attached to the inner wall surface of the side plate of the box bottom frame 21, when the circular bushing is forced to move, the leaf spring 51 is compressed. After the wind load is removed, the compressed leaf spring returns to its original state under its own elastic force. At this time, no bending fatigue is caused to the shear pin, thereby increasing the service life of the shear pin.

[0055] Advantage 2: In the event of a large external force such as an earthquake, the shear pin is sheared off from the shear annular groove, the upper shear pin is connected to the upper support plate 11, and the sunken component 4 falls under its own gravity, the limit column 412 slides down in the circular bushing, and the lower end of the limit column 412 falls to the bottom of the bottom frame 21 of the box body. During the sinking process of the sunken component 4, the lower shear pin 32 is driven to sink, so that the lower end surface of the upper shear pin 31 is separated from the upper end surface of the lower shear pin 32 by a distance. When horizontal displacement occurs between the resettable wind-resistant support and the upper support plate and the lower support plate of the support, the cross section of the shear pin does not contact, avoiding damage to the resettable wind-resistant support and other parts of the support except the shear pin caused by the earthquake. After the earthquake, the shear pin can be replaced, and the rubber isolation enters the isolation working state. This method greatly improves the service life of the isolation rubber support and also improves the reliability of the isolation rubber support.

[0056] Advantage 3: The shear pin positioning ball panel 12 and the shear pin fastening ball panel 42 of the resettable sunken wind-resistant bearing adopt a spherical structure, which is convenient for the leveling function of the leveling bolt and can effectively avoid the component space limitation of the resettable sunken wind-resistant bearing after the shear pin body is cut off.

[0058] The limiting post 412 and the circular bushing 52 are clearance-fitted, and silicone grease or toner is provided between the limiting post 412 and the circular bushing 52 to reduce the resistance between the limiting post and the circular bushing.
