Description

Technical Field

[0001] The present application relates to the technical field of building protection, and in particular to a fire protection device for a building seismic isolation support. Background Art

[0002] Building seismic isolation technology is to extend the building structure period by installing seismic isolation devices, and give the structure greater damping to reduce the transmission of horizontal seismic energy to the upper structure, so as to reduce the acceleration response of the upper structure, thereby ensuring the safety of the upper structure and internal personnel and equipment. Seismic isolation bearings have multiple functions of vertical force transmission components and horizontal seismic isolation components in the seismic isolation structure system. They are currently a widely used seismic isolation device that can isolate or dissipate seismic energy to ensure structural safety.

[0003] In the related art, the seismic isolation bearing is usually directly set between the upper structure and the lower structure, and no fire protection measures are set. In the seismic isolation bearing, multiple layers of rubber and multiple layers of steel plates are usually alternately stacked, and the rubber is connected to the steel plate. Due to the insufficient fire resistance of the rubber, the rubber will gradually degrade when the temperature rises. At the same time, the connection between the rubber and the steel plate will gradually fail, and the air will penetrate from the gap between the steel plate and the rubber and cause violent combustion. In this process, the seismic isolation bearing is compressed, which will cause the rubber and steel plate to slide in different layers, resulting in the continuous deterioration of the seismic isolation bearing and the eventual loss of bearing capacity, causing serious consequences such as uneven settlement or even collapse of the upper structure, posing a huge safety hazard.

DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present application. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment.

[0033] like Figures 1 to 3 As shown, the building seismic isolation bearing fire protection device 100 includes an upper column 10, a lower column 20, a seismic isolation bearing 30 and a fire protection assembly 40. The upper column 10 and the lower column 20 are arranged opposite to each other, and a receiving gap 50 is provided between the upper column 10 and the lower column 20. The upper column 10 has a first surface 11 facing the lower column 20, and the lower column 20 has a second surface 21 facing the upper column 10. The seismic isolation bearing 30 is located in the receiving gap 50 and is connected to the first surface 11 and the second surface 21. The fire protection assembly 40 is provided on the side wall of the upper column 10 and / or the lower column 20, and the fire protection assembly 40 surrounds the axis of the upper column 10, and at least part of the fire protection assembly 40 is movable. When a fire signal occurs, at least part of the fire protection assembly 40 moves to the receiving gap 50 to cover the receiving gap 50.

[0034] In the embodiment of the utility model, the building seismic isolation bearing fire protection device 100 includes an upper column 10, a lower column 20, a seismic isolation bearing 30 and a fire protection assembly 40. The upper column 10 is arranged opposite to the lower column 20, and there is a receiving gap 50 between the upper column 10 and the lower column 20. The seismic isolation bearing 30 can be arranged in the receiving gap 50, so that the upper column 10 and the lower column 20 can be isolated by the seismic isolation bearing 30. When disasters such as earthquakes occur, the seismic isolation bearing 30 can dissipate the seismic energy and reduce the ability to be transmitted to the upper column 10, thereby ensuring the safety of the upper column 10 structure and the personnel in the building. Specifically, the upper column 10 has a first surface 11 facing the lower column 20, and the lower column 20 has a second surface 21 facing the upper column 10. The seismic isolation bearing 30 can be arranged in the receiving gap 50 and connected to the first surface 11 and the second surface 21, so that the seismic isolation bearing 30 can be arranged between the upper column 10 and the lower column 20 to achieve seismic isolation. A fireproof assembly 40 is provided on the side wall of the upper column 10 and / or the lower column 20, and at least part of the fireproof assembly 40 is movable. Therefore, in the event of a fire signal, at least part of the fireproof assembly 40 can be moved to the accommodation gap 50. Since the fireproof assembly 40 surrounds the axis of the upper column 10, when the fireproof assembly 40 moves to the accommodation space, the fireproof assembly 40 can block the accommodation gap 50 and seal the seismic isolation bearing 30 in the accommodation gap 50, as shown in FIG. Figure 2 , Figure 3 As shown, when a fire signal appears, the fire protection assembly 40 can protect the seismic isolation bearing 30 to prevent the seismic isolation bearing 30 from being burned, causing the seismic isolation bearing 30 to continuously deteriorate and lose its bearing capacity, thereby avoiding the occurrence of settlement or even collapse of the upper column 10.

[0035] Among them, the upper column 10 and the lower column 20 are arranged in the vertical direction, the upper column 10 is located at the top, and the lower column 20 is located at the bottom. The seismic isolation bearing 30 is arranged between the upper column 10 and the lower column 20, which can isolate the seismic energy transmitted by the lower column 20 to prevent it from being transmitted to the upper column 10.

[0036] It should be noted that in the related art, even if some fireproof structures are set for seismic isolation bearings, the fireproof structures are fixed on both the upper column and the lower column, and the fireproof structures cover the accommodation gap. However, in this setting method in the related art, if an earthquake or other situation occurs, causing the seismic isolation bearing to have a large displacement, the upper column and the lower column are relatively misaligned, which will cause the fireproof structure to fall off.

[0037] Considering that the probability of an earthquake and a fire occurring at the same time is extremely low, therefore, the device proposed in the present application does not work when an earthquake occurs, that is, the fireproof assembly 40 generally does not block the accommodation gap 50 during an earthquake, and blocks the accommodation gap 50 when a fire occurs, and there is generally no earthquake at this time. Specifically, in the present application, a fireproof assembly 40 is provided on the side wall of the upper column 10 and / or the lower column 20. Specifically, the fireproof assembly 40 can be provided on the side wall of the upper column 10, or the fireproof assembly 40 can be provided on the side wall of the lower column 20, that is, the fireproof assembly 40 can be provided on one of the upper column 10 and the lower column 20. In the event of a fire signal, the fireproof assembly 40 can be moved to abut against the other of the upper column 10 and the lower column 20, so that the fireproof assembly 40 blocks the accommodation gap 50 and protects the seismic isolation bearing 30. In the above-mentioned setting method, the fire protection component 40 is separately set as a whole on one of the upper column 10 and the lower column 20. In the absence of a fire signal, the fire protection component 40 as a whole is not connected to the upper column 10 and the lower column 20 at the same time. Even if the upper column 10 and the lower column 20 are misaligned, the fire protection component 40 can also maintain the current setting state to avoid the rubber bearing offset causing the fire protection component 40 to fall off, lose its fire protection effect or fall down and damage other structures. Alternatively, the fireproof component 40 can also be arranged on the side walls of the upper column 10 and the side walls of the lower column 20. Specifically, the fireproof component 40 can include two separated parts, one part of which is arranged on the side wall of the upper column 10, and the other part is arranged on the side wall of the lower column 20. In the event of a fire signal, the two parts of the fireproof component 40 can be moved so that the two parts of the fireproof component 40 abut against each other, so that the fireproof component 40 covers the accommodating gap 50 and protects the seismic isolation bearing 30. In this setting, in the absence of a fire signal, the two parts of the fireproof component 40 are respectively connected to the upper column 10 and the lower column 20. Even if an earthquake or other situation occurs, causing the seismic isolation bearing 30 to have a large offset and causing the upper column 10 and the lower column 20 to be misaligned, the two parts of the fireproof component 40 can also maintain the current setting state to avoid the problem of the fireproof component 40 falling off due to the offset of the rubber bearing, losing the fireproof effect or falling down and damaging other structures.

[0038] In addition, the building seismic isolation support fire protection device 100 proposed in the present application will only work to shield the accommodation gap 50 when there is a fire signal. Figure 2 , Figure 3 As shown, in the absence of a fire signal, the receiving gap 50 is exposed. Figure 1 Therefore, under normal circumstances, the accommodation gap 50 is not blocked, and the seismic isolation bearing 30 is in an observable state, so that the user can directly observe the working state of the seismic isolation bearing 30 at any time, avoiding the problem that the setting of the fire protection component 40 affects the daily observation, maintenance and inspection of the seismic isolation bearing 30, and allowing the rubber bearing to work normally.

[0039] It should also be noted that the upper column 10 and the lower column 20 can also be in different forms, for example, they can be rectangular columns, or they can be cylindrical, and the fireproof assembly 40 is arranged on the side wall of the upper column 10 and / or the lower column 20, and surrounds the axis of the upper column 10, that is, the fireproof assembly 40 surrounds the upper column 10, and can also be in a circular ring shape, or it can also be in a square frame shape. Of course, the upper column 10 and the lower column 20 can also be in other forms, such as a pentagonal column, etc. The specific forms of the upper column 10 and the lower column 20 are not specifically limited in the embodiments of the utility model. When the upper column 10 and the lower column 20 are rectangular columns and the fireproof assembly 40 is arranged on one of the upper column 10 and the lower column 20, the fireproof assembly 40 can be 4 plates, and the 4 plates are respectively arranged on the side walls of the upper column 10 and the side walls of the lower column 20; or the fireproof assembly 40 can also be an integral frame structure, and the integral frame structure is sleeved on the periphery of the upper column 10 or the lower column 20; when the upper column 10 and the lower column 20 are rectangular columns and the fireproof assembly 40 is arranged on the upper column 10 and the lower column 20, the fireproof assembly 40 can be 8 plates, 4 of which are respectively arranged on the side walls of the upper column 10, and the other 4 are respectively arranged on the side walls of the lower column 20; or the fireproof assembly 40 can also be an integral frame structure, and the two integral frame structures are respectively sleeved on the periphery of the upper column 10 and the lower column 20. When the upper column 10 and the lower column 20 are in other forms, they can also be arranged according to the above description, and the embodiments of the present utility model will not be described in detail here.

[0040] In addition, in some embodiments, Figure 1 , Figure 2 , Figure 3 As shown, the fire protection assembly 40 may include a fire protection board 41. The fire protection board 41 is arranged on the side wall of the upper column 10 and / or the lower column 20. The fire protection board 41 surrounds the axis of the upper column 10 and is movable. When a fire signal occurs, the fire protection board 41 moves to the accommodating gap 50 to cover the accommodating gap 50.

[0041] The fireproof assembly 40 includes a fireproof board 41. Specifically, the fireproof board 41 can also be set on the side wall of the upper column 10, or on the side wall of the lower column 20, or the fireproof board 41 can also include two parts, which are respectively set on the side wall of the upper column 10 and the side wall of the lower column 20. The fireproof board 41 surrounds the axis of the upper column 10 to form a fireproof assembly 40 that can block the accommodating gap 50. Since the fireproof board 41 is movable, when a fire signal occurs, the fireproof board 41 can be moved to the accommodating gap 50, so that the fireproof board 41 can block the accommodating gap 50 to protect the seismic isolation bearing 30.

[0042] It should be noted that, when the upper column 10 and the lower column 20 are rectangular columns and the fireproof board 41 is arranged on one of the upper column 10 and the lower column 20, the fireproof board 41 can be 4 panels, and the 4 panels are respectively arranged on the side wall of the upper column 10 or the side wall of the lower column 20; or the fireproof board 41 can also be a whole of a square structure formed by connecting 4 panels end to end, and the whole of the square structure is sleeved on the periphery of the upper column 10 or the lower column 20; when the upper column 10 and the lower column 20 are rectangular columns, and the fireproof board 41 is arranged on the upper column 10 and the lower column 20, the fireproof board 41 can be 8 panels, 4 of which are respectively arranged on the side wall of the upper column 10, and the other 4 are respectively arranged on the side wall of the lower column 20; or the fireproof board 41 can also be two whole of square structures formed by connecting 4 panels end to end, and the two whole of square structures are respectively sleeved on the periphery of the upper column 10 and the lower column 20. When the upper column 10 and the lower column 20 are in other forms, they can also be arranged according to the above description, and the embodiments of the present utility model will not be described in detail here.

[0043] In addition, in some embodiments, Figure 1 , Figure 2 As shown, a first guide rail 12 may also be provided on the side wall of the upper column 10; when the fire protection board 41 is provided on the side wall of the upper column 10, at least a portion of the fire protection board 41 is embedded in the first guide rail 12, and the fire protection board 41 is movable relative to the first guide rail 12; when the fire protection board 41 is provided on the side wall of the lower column 20, and a fire signal occurs, the fire protection board 41 moves relative to the lower column 20 to block the accommodating gap 50, and a portion of the fire protection board 41 is embedded in the first guide rail 12.

[0044] A first guide rail 12 is also provided on the side wall of the upper column 10. When the fireproof board 41 is provided on the side wall of the upper column 10, at least part of the fireproof board 41 can be embedded in the first guide rail 12, and the fireproof board 41 is movable relative to the first guide rail 12. Therefore, when a fire signal occurs, the fireproof board 41 can move in the first guide rail 12 so that the fireproof board 41 can move in the direction of the lower column 20, so that the fireproof board 41 can block the accommodating gap 50 and protect the seismic isolation bearing 30 located in the accommodating gap 50; when the fireproof board 41 is provided on the side wall of the lower column 20, the fireproof board 41 can be opposite to the first guide rail 12. When a fire signal occurs, the fireproof board 41 can move relative to the lower column 20 toward the upper column 10, so that part of the fireproof board 41 can be embedded in the first guide rail 12. At this time, the fireproof board 41 can block the accommodating gap 50 and protect the seismic isolation bearing 30 located in the accommodating gap 50.

[0045] It should be noted that, when fireproof panels 41 are provided on both the upper column 10 and the lower column 20, the fireproof panels 41 on the side walls of the upper column 10 can be embedded in the first guide rail 12 and movable relative to the first guide rail 12, and the fireproof panels 41 at the lower column 20 can be movably provided on the side walls of the lower column 20. When a fire signal occurs, the fireproof panels 41 in the first guide rail 12 move toward the lower column 20, and the fireproof panels 41 at the lower column 20 move toward the upper column 10, so that the fireproof panels 41 in the first guide rail 12 and the fireproof panels 41 at the lower column 20 abut against each other to block the accommodating gap 50, thereby protecting the seismic isolation bearing 30 located in the accommodating gap 50.

[0046] In addition, in some embodiments, Figure 1 , Figure 2 As shown, a second guide rail 22 can also be provided on the side wall of the lower column 20; when at least part of the fire protection board 41 is embedded in the first guide rail 12, and a fire signal occurs, the fire protection board 41 moves relative to the upper column 10 to block the accommodating gap 50, and part of the fire protection board 41 is embedded in the second guide rail 22; when the fire protection board 41 is provided on the side wall of the lower column 20, at least part of the fire protection board 41 is embedded in the second guide rail 22, and the fire protection board 41 is movable relative to the second guide rail 22, and when a fire signal occurs, the fire protection board 41 moves relative to the upper column 10 to block the accommodating gap 50, and part of the fire protection board 41 is embedded in the first guide rail 12.

[0047] A second guide rail 22 is also provided on the side wall of the lower column 20. When the fireproof board 41 is provided on the side wall of the upper column 10, at least part of the fireproof board 41 is embedded in the first guide rail 12.

When a fire signal occurs, the fireproof board 41 can move relative to the upper column 10 so that part of the fireproof board 41 is embedded in the first guide rail 12 and blocks the accommodating gap 50, thereby protecting the seismic isolation bearing 30 located in the accommodating gap 50.

[0048] It should be noted that in the embodiment of the utility model, a first guide rail 12 is provided on the upper column 10 and a second guide rail 22 is provided on the lower column 20. The first guide rail 12 and the second guide rail 22 can extend in the direction from the upper column 10 to the lower column 20. The setting of the first guide rail 12 and the second guide rail 22 can limit the movement of the fire prevention board 41, so that the fire prevention board 41 can move along the extension direction of the first guide rail 12 and the second guide rail 22.

[0049] It should also be noted that, in the embodiment of the utility model, when the fireproof board 41 is arranged on the upper column 10, at least part of the fireproof board 41 can be embedded in the first guide rail 12. When a fire signal occurs, the fireproof board 41 can be moved downward so that part of the fireproof board 41 is embedded in the second guide rail 22. In order to make the fireproof board 41 have a better shielding effect on the accommodating gap 50, part of the fireproof board 41 can also be embedded in the first guide rail 12 at this time; when the fireproof board 41 is arranged on the lower column 20, at least part of the fireproof board 41 can be embedded in the second guide rail 22. When a fire signal occurs, the fireproof board 41 can be moved upward so that part of the fireproof board 41 is embedded in the first guide rail 12. In order to make the fireproof board 41 have a better shielding effect on the accommodating gap 50, at this time, part of the fireproof board 41 can also be embedded in the first guide rail 12. The fire board 41 has a better shielding effect on the accommodating gap 50. At this time, it can also be embedded in the second guide rail 22 with part of the fire board 41; when the fire board 41 is set on the upper column 10 and the lower column 20, the fire board 41 at the upper column 10 can be embedded in the first guide rail 12, and the fire board 41 at the lower column 20 can be embedded in the second guide rail 22. When there is a fire signal, the fire board 41 at the upper column 10 moves in the first guide rail 12, and the fire board 41 at the lower column 20 can move in the second guide rail 22, so that the fire board 41 at the upper column 10 and the fire board 41 at the lower column 20 can abut against each other. At this time, the fire board 41 can block the accommodating gap 50 and protect the seismic isolation bearing 30 located in the accommodating gap 50.

[0050] In addition, in some embodiments, the fireproof panel 41 may include a main body and a frame, an inner wall of the frame is provided with a mounting groove, the mounting groove extends along the circumferential direction of the frame, the edge of the main body is embedded in the mounting groove and connected to the bottom of the mounting groove; a main body and a frame are provided on the side walls of the upper column 10 and / or the lower column 20, and the main body and the frame both surround the axis of the upper column 10.

[0051] The fireproof board 41 may include a body and a frame, and a mounting groove is provided on the inner wall of the frame. Since the mounting groove extends along the circumferential direction of the frame, the mounting groove may be provided around the center of the frame and around the frame, so that the two ends of the mounting groove are connected, so that the body may be provided inside the frame, and the edges of the body may be embedded in the mounting groove. The body and the frame are provided on the side walls of the upper column 10 and / or the lower column 20, and the body and the frame both surround the axis of the upper column 10, that is, the fireproof board 41 formed by the body and the frame is also provided around the axis of the upper column 10, so as to shield the accommodation gap 50.

[0052] It should be noted that in order to facilitate setting the main body in the frame and setting the fireproof board 41 on at least one of the upper column 10 and the lower column 20, the fireproof board 41 can be a plurality of panels, each of which includes a main body and a frame.

[0053] It should also be noted that the body can be a gypsum board, calcium silicate fiber board, magnesium oxychloride board, etc., which has good fire resistance. When a fire occurs, the body can withstand the fire, avoiding the problem that the body is damaged so that the seismic isolation support 30 in the accommodation gap 50 is exposed, and the fireproof board 41 loses the protection of the seismic isolation support 30. The frame can be a corrugated steel plate, and the corrugated steel plate can include the body. On the one hand, the corrugated steel plate can fix the body and squeeze the edge of the body to avoid the problem of cracking of the body after the fireproof board 41 is set for a long time. On the other hand, it can also be easy to replace the corrugated steel plate or the body.

[0054] In addition, in some embodiments, Figure 1 , Figure 2 As shown, the fire protection assembly 40 may further include a driving member 42 , the output end of which is connected to the fire protection board 41 , and the driving member 42 is used to drive the fire protection board 41 to move relative to the upper column 10 .

[0055] The fireproof assembly 40 further includes a driving member 42. Since the output end of the driving member 42 is connected to the fireproof board 41, the driving member 42 can drive the fireproof board 41 to move through the output end, so that the fireproof board 41 can move relative to the upper column 10. That is, in the case of a fire signal, the driving member 42 can work and drive the fireproof board 41 to move, so that the fireproof board 41 can cover the accommodation gap 50.

[0056] It should be noted that, according to the above description, the fireproof board 41 can be a plurality of separate panels or a plurality of panels connected end to end to form a whole, and the driving member 42 can also have a variety of setting schemes. In the case where the fireproof board 41 includes a plurality of separate panels, there can also be a plurality of driving members 42, and the plurality of driving members 42 are respectively connected to the plurality of panels; in the case where the fireproof board 41 is a whole formed by a plurality of panels connected end to end, there can be only one driving member 42, which is connected to one position of the whole formed by the plurality of panels connected end to end, or there can also be a plurality of driving members 42, which are connected to a plurality of positions of the whole formed by the plurality of panels connected end to end. In this case, the plurality of driving members 42 need to operate synchronously.

[0057] It should also be noted that the driving member 42 can have a variety of structures, for example, it can be a linear motor, or a linear cylinder, etc. The specific structure of the driving member 42 is not specifically limited in the embodiment of the utility model.

[0058] In addition, in some embodiments, Figure 1 , Figure 2As shown, the fire protection assembly 40 may further include a connecting rod 43, one end of which is connected to the output end of the driving member 42, and the other end of the connecting rod 43 is connected to the fire protection plate 41. The driving member 42 is used to drive the connecting rod 43 to move, so that the connecting rod 43 drives the fire protection plate 41 to move.

[0059] The fireproof assembly 40 further includes a connecting rod 43, wherein one end of the connecting rod 43 is connected to the output end of the driving member 42, and the other end of the connecting rod 43 is connected to the fireproof board 41, that is, the driving member 42 and the fireproof board 41 can be connected by the connecting rod 43, so that when the driving member 42 is working, the driving member 42 can push the connecting rod 43 to move, so that the connecting rod 43 can drive the fireproof board 41 to move. The connecting rod 43, as a transmission structure, can transmit the thrust of the driving member 42 to the fireproof board 41. The setting of the connecting rod 43 can facilitate the setting of the driving member 42. When the connecting rod 43 is not set, when setting the driving member 42, it is necessary to set it according to the stroke of the driving member 42, the initial position of the fireproof board 41 (the position of the fireproof board 41 when no fire occurs), and the size of the accommodating gap 50. If there is a deviation when setting the driving member 42, it is possible that the output end of the driving member 42 and the fireproof board 41 cannot be connected. The arrangement of the connecting rod 43 can facilitate the connection between the driving member 42 and the fireproof board 41 , and facilitate the arrangement of the driving member 42 , so that the driving member 42 can drive the fireproof board 41 to move and cover the accommodating gap 50 .

[0060] It should be noted that the driving member 42 may not be connected to the end of the fireproof board 41 . For example, the output end of the driving member 42 may also be connected to the middle of the fireproof board 41 .

[0061] It should also be noted that at this time, the driving member 42 can also be other structures. For example, the driving member 42 includes a rotating motor and a worm gear, the connecting rod 43 can be a worm, the rotating motor is connected to the worm gear, the worm gear is meshed with the worm, and the rotating motor can drive the worm gear to rotate so that the worm gear can move in a straight line and drive the fireproof board 41 to move.

[0062] In addition, in some embodiments, the fire protection assembly 40 may also include a detector and a controller, and the controller is electrically connected to the detector and the driver 42, and the detector is used to detect a fire signal; when the detector detects the occurrence of a fire signal, the controller controls the driver 42 to operate, so that the driver 42 drives the fire protection board 41 to move along a first direction, so that the fire protection board 41 blocks the accommodation gap 50; when the detector detects that the fire signal disappears, the controller controls the driver 42 to operate, so that the driver 42 drives the fire protection board 41 to move along a second direction, so that the seismic isolation bearing 30 is exposed; wherein the first direction is opposite to the second direction.

[0063] The fire protection component 40 also includes a detector and a controller. The controller is electrically connected to the detector and the driver 42. The detector can detect fire signals, and the detector can send the detection results to the controller. The controller can control the driver 42 to operate according to the detection structure. When the detector detects the occurrence of a fire signal, the controller can control the driver 42 to operate so that the driver 42 drives the fire protection board 41 to move along the first direction, so that the fire protection board 41 blocks the accommodation gap 50; when the detector detects that the fire signal disappears, the controller controls the driver 42 to operate so that the driver 42 drives the fire protection board 41 to move along the second direction, so that the seismic isolation bearing 30 is exposed. That is, in the present application, according to the fire signal detected by the detector, the controller can control the driver 42 to operate according to the fire signal, so as to realize the automatic control of the building seismic isolation bearing fire protection device 100.

[0064] It should be noted that the first direction is opposite to the second direction. When the fireproof board 41 is set on the lower column 20, the first direction is the direction from the lower column 20 to the upper column 10. When the fireproof board 41 moves along the first direction, the fireproof board 41 can move toward the upper column 10 so that the fireproof board 41 can block the accommodation gap 50. The second direction is the direction from the upper column 10 to the lower column 20, which can return the fireproof board 41 to its initial state. When the fireproof board 41 is set on the upper column 10, the first direction is the direction from the upper column 10 to the lower column 20. When the fireproof board 41 moves along the first direction, the fireproof board 41 can move toward the lower column 20 so that the fireproof board 41 can block the accommodation gap 50. The second direction is the direction from the lower column 20 to the upper column 10, which can return the fireproof board 41 to its initial state.

[0065] It should also be noted that the controller can also be connected to a manual control device, so that the building seismic isolation bearing fire protection device 100 can also be started and stopped by manual control, which can avoid the erroneous operation of the driving member 42 when the detector detects an error.

[0066] In addition, in some embodiments, Figure 1 , Figure 2 As shown, a limiting structure 60 can be provided on the upper column 10 and / or the lower column 20. When the fire protection component 40 blocks the accommodating gap 50, the limiting structure 60 abuts against the fire protection component 40. The limiting structure 60 is used to limit the movement of the fire protection component 40.

[0067] A limiting structure 60 may be provided on the upper column 10 and / or the lower column 20. In the event of a fire signal, the fireproof assembly 40 may move relative to the upper column 10 so that the fireproof assembly 40 blocks the accommodation gap 50. After the fireproof assembly 40 blocks the accommodation gap 50, the limiting structure 60 abuts against the fireproof assembly 40, and the movement of the fireproof assembly 40 may be limited by the limiting structure 60 to prevent the fireproof assembly 40 from moving excessively, resulting in a situation where part of the accommodation gap 50 is not blocked.

[0068] It should be noted that the limiting structure 60 can be a baffle, which can be set in the moving direction of the fireproof board 41. For example, when the fireproof board 41 is set on the lower column 20, the baffle can be set on the upper column 10. After the fireproof board 41 moves to completely block the accommodation gap 50, the fireproof board 41 can be connected to the baffle on the upper column 10 to limit the fireproof board 41 and prevent the fireproof board 41 from continuing to move upward; or the limiting structure 60 can also be a limiting ring, and the internal size of the limiting ring is smaller than the size of the end of the connecting rod 43. The limiting ring is sleeved on the connecting rod 43, and the two can move relatively. The limiting ring can also be set in the moving direction of the fireproof board 41. For example, when the fireproof board 41 is set on the lower column 20, the baffle can be set on the lower column 20. After the fireproof board 41 moves to completely block the accommodation gap 50, the end of the connecting rod 43 can be connected to the limiting ring and blocked by the limiting ring to achieve limitation, so as to prevent the fireproof board 41 from continuing to move upward. Figure 2 shown.

[0069] Additionally, in some embodiments, a fire-resistant coating may be provided on the surface of the fire-resistant component 40 .

[0070] Since the fireproof component 40 is arranged on the side walls of the upper column 10 and the lower column 20, when a fire occurs, the fireproof component 40 is located on the outside and withstands the burning. In order to provide the fireproof effect of the fireproof component 40, a fireproof coating can be provided on the surface of the fireproof component 40.

[0071] It should be noted that the fireproof coating can be specifically provided on the fireproof board 41. When the fireproof assembly 40 further includes a driving member 42 and a connecting rod 43, the fireproof coating can also be provided on the surface of the driving member 42 and the surface of the connecting rod 43. When a limiting structure 60 is also provided on the upper column 10 and / or the lower column 20, the surface of the limiting structure 60 can also be provided with a fireproof coating.

[0072] It should also be noted that the fire-retardant coating can be formed by spraying a fire-retardant paint on the surface of the fire-retardant component 40. The fire-retardant coating can include inorganic film-forming materials, such as silicates, silica sols, phosphates, etc. The specific formation of the fire-retardant coating is not specifically limited in the embodiments of the present utility model.

[0073] In addition, the building seismic isolation bearing fire protection device 100 proposed in the present application can also work in conjunction with the sprinkler system, that is, when there is a fire signal, the fire protection component 40 moves to block the accommodating gap 50, and water and other fire extinguishing agents can be sprayed through the sprinkler system. On the one hand, it can prevent the fire from spreading further and facilitate fire extinguishing; on the other hand, it can also reduce the burning of the fire protection component 40 by the fire, and can increase the fire resistance of the fire protection component 40, so that the fire protection component 40 can last longer, thereby buying time for fire extinguishing.

[0074] In the embodiment of the utility model, the building seismic isolation bearing fire protection device 100 includes an upper column 10, a lower column 20, a seismic isolation bearing 30 and a fire protection assembly 40. The upper column 10 is arranged opposite to the lower column 20, and there is a receiving gap 50 between the upper column 10 and the lower column 20. The seismic isolation bearing 30 can be arranged in the receiving gap 50, so that the upper column 10 and the lower column 20 can be isolated by the seismic isolation bearing 30. When disasters such as earthquakes occur, the seismic isolation bearing 30 can dissipate the seismic energy and reduce the ability to be transmitted to the upper column 10, thereby ensuring the safety of the upper column 10 structure and the personnel in the building. Specifically, the upper column 10 has a first surface 11 facing the lower column 20, and the lower column 20 has a second surface 21 facing the upper column 10. The seismic isolation bearing 30 can be arranged in the receiving gap 50 and connected to the first surface 11 and the second surface 21, so that the seismic isolation bearing 30 can be arranged between the upper column 10 and the lower column 20 to achieve seismic isolation. A fireproof assembly 40 is provided on the side wall of the upper column 10 and / or the lower column 20, and at least part of the fireproof assembly 40 is movable, so that in the event of a fire signal, at least part of the fireproof assembly 40 can be moved to the accommodation gap 50. Since the fireproof assembly 40 surrounds the axis of the upper column 10, when the fireproof assembly 40 moves to the accommodation space, the fireproof assembly 40 can block the accommodation gap 50 and seal the seismic isolation bearing 30 in the accommodation gap 50, so that when a fire signal appears, the fireproof assembly 40 can protect the seismic isolation bearing 30 to prevent the seismic isolation bearing 30 from being burned, resulting in the seismic isolation bearing 30 continuously deteriorating and losing its bearing capacity, thereby avoiding the occurrence of settlement or even collapse of the upper column 10.
