Description

Technical Field

[0001] The present application relates to the technical field of seismic isolation devices, and in particular to a seismic isolation and earthquake-resistant device for buildings. Background Art

[0002] With the continuous development of cities and the expansion of the population, the number of buildings is increasing day by day. Building safety is an issue that must be considered. The impact of earthquakes on buildings must be considered in the early stages of construction to ensure the safety of subsequent personnel. Existing buildings generally install shock absorbers or seismic isolation bearings as seismic isolation and earthquake resistance devices. The seismic isolation bearing has a simple structure consisting of steel plates and rubber alternately stacked. The steel plate is used as a stiffening material to change the characteristic of the rubber body with low vertical stiffness, so that it can not only reduce the horizontal earthquake effect, but also withstand large vertical loads, and can offset about 80% of the energy of the earthquake, which is a good seismic resistance device. However, existing seismic isolation bearings are generally limited by materials and can only withstand earthquakes of a certain magnitude. When the earthquake amplitude is greater than the range that the seismic isolation bearing material can withstand, the building will produce a large range of displacement, the rubber layer on the seismic isolation bearing will be torn, and the building support will be dislocated, causing the entire building to collapse rapidly and cause greater damage.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0020] like Figure 1-Figure 9 As shown, an embodiment of the present application provides a building seismic isolation and earthquake resistance device, comprising: There are two support plates 1, which are arranged opposite to each other up and down. The two support plates 1 are both provided with convex plates 2 on their opposite surfaces. The two support plates 1 are rectangular, one is installed on the upper end of the concrete steel support pillar of the building, and the other is installed on the lower end of the concrete steel support pillar of the building. The two support plates 1 are arranged opposite to each other up and down, and the convex plates 2 are protrudingly constructed at the center of the support plates 1; The seismic isolation layer 3 comprises a protective rubber frame 301 fixedly connected to the convex plate 2, a top plate 302 is fixedly connected to the top of the protective rubber frame 301, the two top plates 302 are arranged to be opposed to each other, a plurality of laminated rubber plates 303 are arrayed in the protective rubber frame 301 along its height direction, a skeleton steel plate 304 is wrapped between the laminated rubber plates 303, there are two protective rubber frames 301 and they are wrapped on the laminated rubber plates 303 and the skeleton steel plates 304 in an annular shape, the laminated rubber plates 303 and the skeleton steel plates 304 have the same thickness and are staggered and stacked, one end of the protective rubber frame 301 is connected to the support plate 1, and the other end is connected to the top plate 302 on the inner side, the two top plates 302 are arranged to be opposite to each other and fit each other, and the staggered laminated rubber plates 303 and the skeleton steel plates 304 form a columnar block; The amplitude extension part 4 includes an arc-shaped frame plate 401 constructed on the opposite surfaces of the two top plates 302, a disc groove 402 is constructed between the two arc-shaped frame plates 401, and an elliptical limit block 403 is movably placed in the disc groove 402. Because the two top plates 302 are set to be in contact with each other, the self-gravity of the building always applies a downward force to the upper top plate 302, so that the top plate 302 will not easily separate from the lower top plate 302. When an earthquake occurs, the horizontal load of the earthquake will push the two top plates 302 to move horizontally. When the top plates 302 move horizontally, the arc-shaped frame plate 401 will contact the elliptical limit block 403 and apply a horizontal thrust to it. At this time, the elliptical limit block 403 will apply a reverse resistance force to the arc-shaped frame plate 401, and the two will rub against each other. At the same time, the elliptical limit block 403 will be affected by the arc-shaped frame plate 401 is deformed by the movement, and part of the load is absorbed by deformation and friction, so as to reduce the energy impact of the earthquake on the seismic isolation layer 3. In addition, because the two top plates 302 are in contact with each other, the horizontal potential energy of the earthquake is divided into two parts. One part causes the upper seismic isolation layer 3 to deform, that is, the skeleton steel plates 304 are dislocated from each other, and the laminated rubber plate 303 is deformed to absorb the potential energy. The other part causes the lower seismic isolation layer 3 to deform, and another part is transferred to the elliptical limit block 403, which reduces the load on the seismic isolation layer 3, greatly improves the horizontal vibration bearing capacity of the device, reduces the damage of the vibration to the seismic isolation layer 3, and prevents the protective rubber frame 301 and the laminated rubber plate 303 from being easily torn, thereby causing the building to fall, thereby increasing the seismic isolation and earthquake resistance of the building. There are multiple U-shaped isolation plates 5 connected between the two isolation layers 3. The two isolation layers 3 are connected together through the U-shaped isolation plates 5, so that their original independent structures and mutual adhesion are transformed into mutual adhesion and connection. The U-shaped isolation plates 5 are connected to the circumferential side of the isolation layer 3. On the one hand, they can partially absorb the horizontal loads of the two isolation layers 3 during an earthquake, and convert the loads into deformation of the U-shaped isolation plates 5, which further reduces the horizontal loads borne by the isolation layers 3. On the other hand, they can also absorb vertical vibration loads and offset the loads by deformation. At the same time, they also increase the reset ability of the isolation layer 3 after vibration displacement, cooperate with the deformation recovery of the elliptical limit block 403, and push the isolation layer 3 to reset, avoid excessive dislocation of the two isolation layers 3 and separation, and ensure the safety of the building.

[0021] like Figure 3As shown, in some embodiments, the support plate 1 includes a flat plate 101, and two stepped holes 102 are configured at the four corners of the upper surface of the flat plate 101. A T-shaped gasket 103 is inserted into the stepped hole 102, and a long-rod bolt 104 is movably installed in the T-shaped gasket 103. The bottom of the long-rod bolt 104 is threadedly connected with a connecting sleeve 105 that abuts against the bottom of the support plate 1. It should be noted that the connecting sleeve 105 is preset in the concrete steel bar pillar of the building, and the long-rod bolt 104 is connected to the connecting sleeve 105, so that the flat plate 101 can be firmly connected to the concrete. A stepped hole 102 is provided at the end of the soil reinforcement support to effectively limit the T-type washer pipe, and a T-type washer pipe 103 is inserted into the stepped hole 102 to support the long rod bolt 104, thereby preventing the nut part of the long rod bolt 104 from directly contacting the plate 101, reducing the friction loss caused by vibration between the plate 101 and the long rod bolt 104 during an earthquake, and improving the service life. In addition, the T-type washer pipe 103 is used to receive the long rod bolt 104, which increases the contact area with the plate 101 and improves the connection stability between the plate 101 and the connecting sleeve 105.

[0022] like Figure 2 and Figure 6 As shown, in some embodiments, three rubber cylinders 3031 are arranged in an array along the circumference between the multiple laminated rubber plates 303, and the rubber cylinders 3031 penetrate the multiple skeleton steel plates 304. The support plate 1 and the convex plate 2 are provided with three end holes 201 connected to the rubber cylinders 3031. The end holes 201 are threadedly connected with sealing blocks 202. The sealing blocks 202 can seal the rubber cylinders 3031 to form a sealed space inside. It should be noted that, in one embodiment, the rubber cylinders 3031 are filled with a medicine for repairing rubber. The medicine The agent is stored in the glass bottle, such as nitrile-phenolic adhesive, which is mainly used for bonding rubber and metal. When an earthquake occurs, the glass bottle is broken due to the vibration of the seismic isolation layer 3, and the nitrile-phenolic adhesive therein leaks out. Due to the occurrence of the earthquake, tearing may occur between the laminated rubber plate 303 and the skeleton steel plate 304, as well as the rubber column 3031. At this time, the leaked nitrile-phenolic adhesive can enter along the cracks, repair and bond the laminated rubber plate 303 and the skeleton steel plate 304, thereby ensuring the subsequent earthquake resistance of the device and improving the safety of the building.

[0023] like Figure 2As shown, in some embodiments, a lead rod 6 is also included, and the lead rod 6 includes a column 601 inserted in the rubber cylinder 3031, and the end of the column 601 is fixedly connected with a threaded column 602 threadedly connected to the end hole 201, and the end of the threaded column 602 is constructed with a hexagonal nut 603. By constructing the threaded column 602 on the column 601, it can be convenient for disassembly and replacement. When the device is installed, it can be determined whether to install the lead rod 6 or the sealing block 202 according to needs, thereby increasing the flexibility of the device. It should be noted that in another embodiment, the lead rod 6 can also be inserted in the rubber cylinder 3031. By inserting the lead rod 6 between multiple laminated rubber plates 303 and the skeleton steel plate 304, it can be horizontally limited. When an earthquake occurs, the lead rod 6 will be subjected to the lateral shear force of the laminated rubber plates 303 and the skeleton steel plate 304, thereby absorbing part of the horizontal load, further reducing the damage of the seismic potential energy to the seismic isolation layer 3, and improving the bearing capacity of the device.

[0024] like Figure 4-Figure 8 As shown, in some embodiments, the skeleton steel plate 304 is annular and has a beveled perforation 3041 therein, a buffer gap 3042 is constructed between the beveled surface of the beveled perforation 3041 and the outer arc surface of the arc frame plate 401, and the laminated rubber plate 303 includes a ring plate 3032 fixedly connected to the inner side of the protective rubber frame 301, and an arc-shaped supporting plate 3033 filled in the buffer gap 3042 is constructed on the inner side of the ring plate 3032. The beveled perforation 3041 is set in the middle of the skeleton steel plate 304, which can contact the arc surface of the arc supporting plate 3033. When an earthquake occurs, part of the horizontal load can be absorbed through the beveled perforation 3041 and the arc surface of the arc supporting plate 3033. The surface friction is converted into a longitudinal load, which, on the one hand, reduces the lateral load between the laminated rubber sheet 303 and the skeleton steel plate 304. The longitudinal bearing capacity of the columnar seismic isolation layer 3 is much greater than the lateral bearing capacity, so the damage caused by the earthquake to the seismic isolation layer 3 can be greatly reduced. On the other hand, the arc-shaped support plate 3033 and the bevel perforation 3041 conflict with each other, which can limit the relative displacement between the skeleton steel plates 304 to a certain extent, thereby reducing the deformation of the laminated rubber sheet 303, reducing the risk of damage to the laminated rubber sheet 303, increasing the service life of the device, and reducing the amplitude of the building caused by the earthquake, thereby improving the safety of the building.

[0025] like Fig. 9As shown, in some embodiments, the elliptical limit block 403 includes an elliptical rubber shell 4031, and a plurality of laminated cavities 4032 are arrayed along the height direction of the elliptical rubber shell 4031, and the laminated cavities 4032 are filled with circular steel plates 4033. Compared with the pure rubber elliptical limit block 403, filling the elliptical rubber shell 4031 with a plurality of circular steel plates 4033 can increase its longitudinal structural strength, improve the longitudinal bearing capacity of the elliptical limit block 403, and effectively absorb the longitudinal and transverse loads transmitted by the isolation layer 3. Moreover, because it exists independently and is not connected to the arc frame plate 401, the elliptical limit block 403 will directly consume energy after deformation, and part of the energy will be re-transmitted to the arc frame plate 401 through friction, so that the overall load on the isolation layer 3 is reduced, thereby improving the bearing range of the device.

[0026] like Figure 2 , Figure 5 and Fig. 9 As shown, in some embodiments, the diameter of the circular steel plate 4033 decreases from the middle to the upper and lower sides, the arc surfaces on the upper and lower sides of the elliptical rubber shell 4031 fit with the inner concave surface of the arc frame plate 401, and an active cavity 4021 is constructed between the horizontal arc surface of the elliptical rubber shell 4031 and the edge of the disc groove 402. The setting of the active cavity 4021 mainly allows a certain activity space between the elliptical limit block 403 and the disc groove 402, so that the elliptical limit block 403 can be deformed in this space, and when the deformation is restored, the energy will not be completely transmitted back to the seismic isolation layer 3, thereby increasing safety. The circular steel plate 4033 is set as a circular plate with decreasing sizes, so that the elliptical limit block 403 is more likely to deform, so as to absorb energy.

[0027] like Figure 4 and Figure 7As shown, in some embodiments, the U-shaped damping plate 5 includes two horizontal connecting plates 501, one of which is connected to the upper protective rubber frame 301, and its end is connected to the convex plate 2 or the skeleton steel plate 304 or the top plate 302, and the other horizontal connecting plate 501 is connected to the lower protective rubber frame 301, and its end is connected to the convex plate 2 or the skeleton steel plate 304 or the top plate 302. An arc plate 502 located on the outside of the protective rubber frame 301 is connected between the two horizontal connecting plates 501. The two isolation layers 3 can be connected together through the U-shaped damping plate 5, so that the two isolation layers 3 will not be easily dislocated and detached when an earthquake occurs. The arc plate 502 is connected between the horizontal connecting plates 501, and the material of the arc plate 502 is made of steel plate. When an earthquake occurs, the isolation Layer 3 will transfer the downward potential energy to the skeleton steel plate 304 and the laminated rubber plate 303, and absorb the potential energy through the up and down squeezing of the laminated rubber plate 303. Part of the upward potential energy is offset by the influence of the building gravity, and the other part will be transferred to the curved plate 502 through the horizontal connecting plate 501, and the potential energy will be offset by the deformation of the curved plate 502. The curved plate 502 will also pull the two seismic isolation layers 3 together to apply a force to make the two seismic isolation layers 3 not easily separate by too much distance, so as to prevent the seismic isolation layers 3 from detaching and increase safety. Part of the horizontal load will also be applied to the curved plate 502, and this part of the load will be consumed by its bending deformation, thereby further reducing the load borne by the seismic isolation layer 3 and ensuring the stability of the structure.

[0028] like Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, the ends of the multiple U-shaped anti-dissipation plates 5 are connected to the convex plates 2, the skeleton steel plate 304 and the top plate 302 in the two protective rubber frames 301 in sequence from top to bottom, and the U-shaped anti-dissipation plates 5 are distributed in a spiral array, such as Figure 1 As shown, one end of the U-shaped damping plate 5 is connected to the convex plate 2 in the upper protective rubber frame 301, and the other end is connected to the top plate 302 in the lower protective rubber frame 301, and so on to form a spiral distribution. Such a structure not only makes the U-shaped damping plate 5 consistent in size and shape, ensuring their ability to bear the same load, but also can evenly distribute the load between the various layers of the isolation layer 3, avoiding stress concentration and causing the U-shaped damping plate 5 to break, thereby increasing safety.

[0029] like Figure 7 As shown, in some embodiments, the length of the horizontal connecting plate 501 is not greater than the radius length of the arc plate 502. To ensure the bearing capacity of the U-shaped heat-blocking plate 5, the shorter length of the horizontal connecting plate 501 can transfer most of the load to the arc plate 502, and utilize the deformation of the arc surface to consume the load, thereby preventing the horizontal connecting plate 501 from being broken due to excessive load, thereby improving the bearing capacity of the U-shaped heat-blocking plate 5.

[0030] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
