Description

Technical Field

[0001] The present invention belongs to the technical field of seismic isolation bearings, and more specifically, particularly relates to a friction pendulum bearing based on building warehouse seismic isolation and a component replacement method. Background Art

[0002] As a type of grain storage warehouse with great promotion value, building warehouse plays an important role in improving land utilization and grain storage effect. With the same area as bungalow warehouse, building warehouse can store more than three times more grain than bungalow warehouse. In recent years, earthquakes have occurred frequently in many regions of my country. At present, most of the research on bulk grain building warehouse is structural system design. The structure form used more in grain storage environment and process is reinforced concrete frame structure. Therefore, the research on building warehouse mainly focuses on the seismic performance of frame structure, while the research on seismic isolation bearings suitable for building warehouse involves less. Since friction pendulum bearings can offset part of the vibration or vibration energy and have good seismic performance, they can be widely used in building warehouse seismic reduction and isolation.

[0003] After searching, it is found that the friction pendulum bearings in the existing technology of engineering structures mainly have the following technical improvement directions: 1. Anti-pullout: In the disclosed invention patent "Anti-pullout friction pendulum bearing (202023307854.4)", the connecting block is set with the arc-shaped sliding grooves on both sides of the longitudinal support plate and the arc-shaped sliding grooves on both sides of the transverse support plate. During an earthquake, the support plate is connected by the connecting block, and its longitudinal or transverse movement has a large horizontal displacement deformation capacity. The sliding surface of the transverse support plate is made of special metal and polymer wear-resistant material, and has a low friction coefficient and high damping effect. Its special arc-shaped sliding groove can make it return to the equilibrium position by relying on the gravity carried on it, and has strong automatic reset ability and strong anti-pullout ability. In the disclosed invention patent "Anti-pullout friction pendulum bearing (202222943859.9)", the anti-pullout performance is also improved by setting a sealing plate. In the disclosed invention patent "Anti-pullout friction pendulum bearing (202223532873.6)", the anti-pullout problem is also solved. There are many improvement studies in this direction.

[0004] 2. Reduce friction: In the disclosed invention patent "A tensile friction pendulum bearing (202023307854.4)", a stainless steel plate or chrome-plated layer is provided on the bottom surface of the upper bearing plate and the top surface of the lower bearing plate, and a silicone grease storage pit is provided on the surface of the upper spherical slide plate and the lower spherical slide plate, and silicone grease is applied to reduce the sliding friction and wear between the upper and lower bearing plates and the damping block, thereby increasing the service life of the device and reducing the subsequent maintenance cost. In the disclosed invention patent "Friction-reducing and wear-resistant friction pendulum isolation bearing (202023307854.4)", a wear-resistant and corrosion-resistant coating is provided on the lower surface of the upper bearing plate. When the upper bearing plate and the spherical crown plate move, the friction coefficient is small, the wear resistance is good, and the anti-corrosion effect is good. The wear-resistant and corrosion-resistant coating not only reduces the friction coefficient, but also prevents the upper bearing plate from corroding and rusting due to contact with humid air during use, thereby extending the overall service life of the bearing and reducing maintenance costs.

[0005] 3. Replacement of parts: The authorized invention patents "Replacement method of friction pendulum bearing and its shear limit pin (201710042257.7)", "Removal structure of broken limit pin of friction pendulum bearing after earthquake (201620521596.4)", and "Multi-stage energy-absorbing friction pendulum bearing with replaceable limit device (201720745278.0)" all solve the problem of how to replace the limit device (pin) of the friction pendulum bearing.

[0006] Based on the above research improvement direction, combined with the inventor's experience and summary, it is believed that in the friction pendulum bearing technology, it is important to use various technical means to protect the components and extend the life of the components. However, the bearing is subject to external force vibration all year round, and trying to protect the components is only a technical means to ensure the reliability of the bearing in a short period of time. In the long run, the technical means of replacing key components are the ultimate means to ensure the performance of the entire bearing. The inventor believes that the more important parts than replacing the above limit pins are the sliders and related components that are in a state of long-term stress wear, so this problem should be taken seriously and solutions should be sought to ensure that the structure of the building warehouse is not easily damaged by earthquakes for a long time.

[0007] Relying on the granary research platform of the applicant's unit, the applicant team of the present invention has improved the above-mentioned deficiencies and proposed a friction pendulum bearing and component replacement method based on building warehouse seismic isolation.

[0017] A method for replacing components of a friction pendulum support, wherein the steps for replacing the sliding component 2 are as follows: S1. Clear out the grain stored in the warehouse to reduce the overall weight of the warehouse; S2. Insert three crowbars into three driving devices respectively, and rotate the driving devices with force at the same time. At this time, the threaded rod threadedly connected with the driving device gradually rises from the lifting cylinder until the force ring is completely engaged with the annular groove, and the threaded rod cannot rise any further under normal force. S3. The lubricating oil is introduced into the oil immersion groove inside the sliding cylinder, and the lubricating oil is immersed in the gaps of each layer of the thread along the oil immersion hole column; S4. After waiting for a while, use the ends of three "L"-shaped crowbars to hook the force-bearing holes of the force-bearing ears on the sliding component respectively, rotate the force-bearing ears with force, and clamp the sliding cylinder with suitable long pliers. The rotation of the lower limit groove drives the threaded column to gradually descend in the sliding cylinder until the steel ball is out of the upper limit groove, and the worn sliding component is taken out; S5. Put in the new sliding assembly and use an "L"-shaped crowbar to rotate the force ear in the opposite direction, so that the lower limit groove rises and cooperates with the upper limit groove to engage the steel ball; S6. Use a crowbar to reversely rotate the drive device so that the threaded rod is retracted into the lifting cylinder to complete the replacement The present invention has at least the following beneficial effects: 1. In the present invention, since grains need to be dumped and emptied frequently in the building granary, the building granary is easily impacted by external forces of grains and vibrates, and in the earthquake zone it is also affected by earthquake waves. Therefore, installing a friction pendulum support at the bottom of the building granary can offset part of the energy, and the continuous back-and-forth friction between the sliding assembly and the sliding groove can effectively weaken the damage of vibration or vibration to the building granary structure.

[0018] 2. In the present invention, since the sliding assembly is often subject to wear, its effectiveness will decrease year by year in the long run. Therefore, the present application adopts a replaceable sliding assembly to maintain the good performance of the friction pendulum bearing to improve the earthquake resistance of the building warehouse. Specifically, the sliding assembly includes a steel ball, a lower limit groove, a force ear, a threaded column, and a sliding cylinder. By rotating the force ear, the lower limit groove can be lowered as the threaded column is retracted into the sliding cylinder, so that the steel ball is disengaged from the upper limit groove, and the lifting structure bears the gravity of the building warehouse, so that the worn sliding assembly is taken out and replaced with a new sliding assembly, thereby completing the replacement of parts, thereby maintaining the good performance of the sliding assembly to improve the vibration and earthquake resistance of the building warehouse. In addition, the setting of the oil immersion tank and the oil immersion hole column allows lubricating oil to be introduced into them before replacement, making the rotation smoother, more labor-saving and smoother.

[0019] 3. In the present invention, the driving device cooperates with the lifting mechanism, and the rotating driving device causes the threaded rod of the lifting mechanism to rise from the lifting cylinder and press against the upper support, thereby bearing the gravity of the building warehouse during the replacement of the sliding component, so that the replacement can proceed smoothly. In addition, a force ring is fixed on the top of the threaded rod of the lifting mechanism, and can cooperate with the annular groove on the bottom surface of the upper support main board to bear force, so that the gravity of the building warehouse can be dispersed to the three threaded rods, making the force more uniform, and preventing a single threaded rod from being bent or broken due to a greater force.

Insert the new sliding assembly (2), use an "L"-shaped crowbar to reversely rotate the force ear (22) so that the lower limit groove (23) rises and the upper limit groove (12) cooperates to engage the steel ball (21); S6. Use a crowbar to rotate the drive device in the opposite direction so that the threaded rod (41) is recovered into the lifting cylinder (124), completing the replacement.
