A gap plugging device with elastic liquid storage bag and anti-falling plate

Abstract

The present invention relates to a gap plugging device with an elastic liquid storage bag and a liquid-proof plate, which mainly includes a first side plate, a second side plate, an elastic liquid storage bag, a liquid return structure, a first liquid-proof plate and a second liquid-proof plate. The elastic liquid storage bag itself has certain elasticity and strength, and can generate a certain restoring force after being compressed or pulled. When either side of the elastic liquid storage bag is compressed, the compression amplitude of the compressed part is large, and more magnetorheological fluid can be squeezed out, so that the squeezed magnetorheological fluid flows into the reflux structure through the connecting structure, and the flow rate is controlled through the magnetic field area to form a damping effect. The gap plugging device of the present invention can autonomously adjust its own opening and closing degree as the gap opens and closes, which can prevent the gap plugging device from slipping, and then prevent the beam-column node from falling out with its own damping force, and can also drive the deformation node to reset.

Description

Technical Field

[0001] The invention relates to the technical field of building structure reinforcement, and in particular to a gap plugging device with an elastic liquid storage bag and a fall-proof plate. Background Art

[0002] In traditional and modern buildings and structures, gaps between different components frequently occur due to manufacturing errors and installation process requirements. Taking traditional wooden structures as an example, there are often gaps in the top and side walls at the beam-column joints. Working with gaps has become a common working state for structural components. During the long service life, the deadweight and seismic loads will increase the gaps. The impact of environmental factors on materials will also cause the gaps at the beam-column joints to increase. If the gaps are large, the connection of the components will become loose, causing the components to swing horizontally or even twist during an earthquake, which is extremely detrimental to the earthquake resistance of the building.

[0003] The prior art discloses a longitudinal seam caulking device, comprising: a first panel, on which a plurality of guide seats are provided; a second panel, which is arranged opposite to the first panel; a stranded wire, which is wound around the guide seat, a first end of the stranded wire connected to a stranded wire end seat, the stranded wire end seat being fixedly connected to the second panel, a second end of the stranded wire extending out of a space between the second panel and the first panel and connected to a fastening device, the fastening device being capable of tightening and releasing the stranded wire; four sets of elastic components, which are arranged between the first panel and the second panel and close to the corners of the second panel respectively, and a first end of the elastic component is fixedly connected to the first panel The air column is fixedly connected, and the second end of the elastic component is fixedly connected to the second panel; there are two groups of air columns, and the connecting line of one group of air columns intersects with the connecting line of the other group of air columns to form a cross, and each group of air columns includes two air columns, and an air channel and an air groove connected to the first end of the air channel are provided on the first panel corresponding to each of the air columns, and the air column is an elastic hollow cylinder with an opening at the first end and a closed second end, and a first limiting groove is provided on the first panel around the air groove, the first end of the air column is embedded in the first limiting groove and the opening is opposite to the air groove, the second end of the air column abuts against the second panel, and an air nozzle is provided at the second end of the air channel, and the air nozzle is connected to a pressure gauge.

[0004] The above-mentioned existing technology can achieve the function of gap plugging. However, during an earthquake, the gap will open and close repeatedly and irregularly as the earthquake continues, causing the size of the gap to change during the earthquake. The gap plugging device that was originally firmly plugged is very likely to fall off due to the widening of the gap, resulting in the loss of the gap plugging effect, and it is even more impossible to prevent the beam-column node from falling out. Summary of the invention

[0039] The receiver is fixedly arranged on the second side plate and arranged opposite to the transmitter, and is suitable for receiving the signal transmitted by the transmitter.

[0040] The present invention has the following advantages:

[0041] The gap plugging device of the embodiment of the present invention mainly includes a first side plate, a second side plate, an elastic liquid storage capsule, a liquid return structure, a first anti-peeling plate and a second anti-peeling plate. The operator can adjust the first side plate and the second side plate so that the first side plate and the second side plate are opposite to each other, and adjust the distance between the first side plate and the second side plate according to the gap width so that the total thickness of the gap plugging device is slightly smaller than the total width of the gap, and the elastic liquid storage capsule can be compressed to a certain extent. Then, the gap plugging device is embedded into the gap, and the gap plugging device is relaxed. When part of the compression of the elastic liquid storage capsule is released, pressure can be applied to the first side plate and the second side plate, so that the first side plate and the second side plate are respectively tightly fitted with the side walls of the gap.

[0042] The anti-slip protrusions of the first anti-slip plate and the second anti-slip plate can fit tightly with the side walls of the gap, thereby preventing the gap plugging device from escaping from the beam-column node and increasing the applicability of the gap plugging device to gap side walls with concave and convex surfaces.

[0043] On this basis, the gap plugging device with an elastic liquid storage capsule and an anti-slip plate of this embodiment is in a compressed state when embedded in the gap. The elastic liquid storage capsule itself has a certain elasticity and strength, and can continuously provide a certain supporting force to the first side plate and the second side plate, so as to keep the gap plugging device in a natural supporting state in the gap in the direction of the first side plate and the second side plate. When the node vibrates, the elastic liquid storage capsule can be compressed and squeeze out the magnetorheological fluid, and the squeezed magnetorheological fluid flows into the reflux structure through the connecting structure, and the flow rate is controlled when passing through the magnetic field, forming a damping effect.

[0044] The compression amplitude of the compressed part is large, which can squeeze out more magnetorheological fluid, and the more magnetorheological fluid flows through the magnetic field area, the stronger the damping effect is. Therefore, the gap plugging device of the present invention can generate resistance to prevent the beam-column node from falling out, thereby preventing the node from falling out. Since the elastic liquid storage capsule can squeeze the magnetorheological fluid radially in different directions after being compressed, the sensitivity of the device to external loads can be increased.

[0045] To sum up, the gap plugging device with an elastic liquid storage bag and a fall-proof plate in the embodiment of the present invention can overcome the defect that the gap plugging device in the prior art is easily separated from the gap when the gap vibrates, thereby providing a gap plugging device that can autonomously adjust its own opening and closing degree as the gap opens and closes, which can prevent the gap plugging device from slipping and further prevent the beam-column node from falling out by virtue of its own damping force.

DETAILED DESCRIPTION

[0059] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0061] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0062] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0063] like Figure 1 and Figure 2 As shown, the present embodiment relates to a gap plugging device 100 having an elastic liquid storage capsule and a laser emitter 61, including a first side plate 11, a second side plate 12, an elastic liquid storage capsule, a liquid return structure, a first anti-detachment plate 51 and a second anti-detachment plate 52. Among them, the first side plate 11 and the second side plate 12 are arranged opposite to each other. The first end of the elastic liquid storage capsule is fixedly connected to the second side plate 12, and the second end is suitable for abutting against the first side plate 11. The elastic liquid storage capsule is suitable for accommodating magnetorheological fluid. A plurality of connecting structures are formed on the first side plate 11. The first ends of the plurality of connecting structures are evenly distributed around the elastic liquid storage capsule and are connected to the elastic liquid storage capsule.

[0064] The liquid return structure is connected to the second end of the connecting structure, and the volume of the liquid return structure can expand and contract. The electromagnetic component is suitable for adjusting the viscosity of the magnetorheological fluid. The first anti-slip plate 51 is fixedly arranged on the side of the first side plate 11 away from the second side plate 12. A plurality of anti-slip protrusions 53 are formed on the side of the first anti-slip plate 51 away from the first side plate 11. The second anti-slip plate 52 is fixedly arranged on the side of the second side plate 12 away from the first side plate 11, and a plurality of anti-slip protrusions 53 are formed on the side of the second anti-slip plate 52 away from the second side plate.

[0065] The gap plugging device 100 of this embodiment mainly includes a first side plate 11, a second side plate 12, an elastic liquid storage capsule, a liquid return structure, a first anti-detachment plate 51 and a second anti-detachment plate 52. The operator can adjust the first side plate 11 and the second side plate 12 so that the first side plate 11 and the second side plate 12 are opposite to each other, and adjust the distance between the first side plate 11 and the second side plate 12 according to the gap width, so that the total thickness of the gap plugging device 100 is slightly smaller than the total width of the gap, and the elastic liquid storage capsule can be compressed to a certain extent. Then, the gap plugging device 100 is embedded into the gap, and the gap plugging device 100 is relaxed. When the partial compression of the elastic liquid storage capsule is released, pressure can be applied to the first side plate 11 and the second side plate 12, so that the first side plate 11 and the second side plate 12 are respectively tightly fitted with the side walls of the gap.

[0066] The anti-slip protrusions 53 of the first anti-slip plate 51 and the second anti-slip plate 52 can fit tightly with the side walls of the gap, thereby preventing the gap plugging device 100 from escaping from the beam-column node and increasing the applicability of the gap plugging device 100 to gaps with concave and convex side walls.

[0067] On this basis, the gap plugging device 100 with an elastic liquid storage capsule and an anti-slip plate of this embodiment is in a compressed state when embedded in the gap. The elastic liquid storage capsule itself has a certain elasticity and strength, and can continuously provide a certain supporting force to the first side plate 11 and the second side plate 12, so as to keep the gap plugging device 100 in a natural supporting state in the gap in the direction of the first side plate 11 and the second side plate 12. When the node vibrates, the elastic liquid storage capsule can be compressed and squeeze out the magnetorheological fluid, and the squeezed magnetorheological fluid flows into the reflux structure through the connecting structure, and the flow rate is controlled when passing through the magnetic field, forming a damping effect.

[0068] The elastic liquid storage capsule at the pressure point has a larger compression amplitude, which can squeeze out more magnetorheological fluid. When more magnetorheological fluid flows through the magnetic field area, the damping effect is stronger. Therefore, the gap plugging device 100 of the present invention can generate resistance to prevent the beam-column node from falling out, thereby preventing the node from falling out. Since the elastic liquid storage capsule can squeeze the magnetorheological fluid radially in different directions after being compressed, the sensitivity of the device to external loads can be increased.

[0069] To sum up, the gap plugging device 100 of this embodiment with an elastic liquid storage bag and an anti-falling plate can overcome the defect that the gap plugging device 100 in the prior art is easy to fall off from the gap when the gap vibrates, thereby providing a gap plugging device 100 that can autonomously adjust its own opening and closing degree as the gap opens and closes, which can prevent the gap plugging device 100 from slipping, and then prevent the beam-column node from falling out by virtue of its own damping force.

[0070] Preferably, if Figure 3As shown, in this embodiment, the elastic liquid storage capsule includes a capsule body 21, a first connecting section 22 and a second connecting section 23. Among them, the capsule body 21 is suitable for accommodating magnetorheological fluid. There are multiple first connecting sections 22, which are radially distributed along the circumference of the capsule body 21, and the first end of the first connecting section 22 is hinged to the capsule body 21. There are multiple second connecting sections 23, and the multiple second connecting sections 23 are arranged one by one with the first connecting section 22, and can be slidably plugged into the second end of the first connecting section 22, and the second end of the second connecting section 23 is hinged to the connecting structure. Preferably, a sealing structure is also sandwiched between the first connecting section 22 and the second connecting section 23, which can prevent the magnetorheological fluid from leaking from the joint between the first connecting section 22 and the second connecting section 23. The sealing structure is preferably but not limited to an oil seal or a sealing gasket.

[0071] The first connecting section 22 and the second connecting section 23 form a length-adjustable structure, which allows the elastic liquid storage bag to slide relative to the first side plate 11. When the bag body 21 is compressed, the magnetorheological fluid is squeezed out of the bag body 21, and the magnetorheological fluid is squeezed out more at a larger angle of pressure. The squeezed magnetorheological fluid passes through the first connecting section 22 and the second connecting section 23 in sequence, and then flows into the liquid guide pipe 112 through the guide seat, and finally merges into the liquid return structure.

[0072] Preferably, in this embodiment, the communication structure includes a connection seat 111 and a liquid guiding pipeline 112. The connection seat 111 is formed on a side of the first side plate 11 close to the second side plate 12 and is suitable for being hinged to the second end of the second communication section 23. The liquid guiding pipeline 112 is connected between the plurality of connection seats 111 and the liquid return structure.

[0073] The capsule 21 is preferably, but not limited to, a cylinder, a prism or an ellipsoid. Preferably, in the present embodiment, the capsule 21 comprises a closed capsule 21 top, a capsule 21 bottom, and a corrugated capsule side wall with a capsule opening at the bottom. The capsule 21 top is suitable for being fixedly connected to the second side plate 12, and the capsule 21 bottom can be slidably disposed on the first side plate 11. Preferably, the side wall of the capsule 21 is corrugated, which can bend under pressure without being easily damaged, and can form a certain restoring force. Preferably, the capsule 21 is made of a material with a certain strength and rigidity, which can support the first side plate 11 and the second side plate 12, and resist the opening and closing of the first side plate 11 and the second side plate 12 during an earthquake.

[0074] like Figure 3 , 4 , 5 and 6, in this embodiment, a hollow cylinder is formed at the first end of the first connecting section 22, and the peripheral wall of the capsule 21 has openings corresponding to the number of the first connecting sections 22, and the hollow cylinder is clamped in the openings of the capsule 21 and communicated with the capsule 21. A hollow cylinder is formed at the second end of the second connecting section 23, and the hollow cylinder is clamped in the connecting seat 111 and communicated with the connecting seat 111.

[0075] The liquid return structure may be one or more. Preferably, in this embodiment, the liquid return structure and the connecting structure are arranged one by one, and the liquid return structure may be made of an elastic material with an expandable and contractible volume. When the magnetorheological fluid is squeezed out of the capsule 21, the liquid return structure made of the elastic material can expand and accommodate the magnetorheological fluid, and promote the magnetorheological fluid to flow back through its own elastic restoring force.

[0076] Preferably, in this embodiment, the liquid return structure includes a liquid return chamber 31, a piston plate 32 and an elastic structure 33. The liquid return chamber 31 is formed on the first side plate 11. A liquid through hole 114 with a reduced diameter is formed at the connection between the liquid return chamber 31 and the connecting structure. The piston plate 32 is slidably arranged in the liquid return chamber 31, and is suitable for separating a first chamber and a second chamber in the liquid return chamber 31. The first chamber is connected to the connecting structure, and the second chamber is connected to the outside. The elastic structure 33 is connected between the second chamber and the piston plate 32. When there is no magnetorheological fluid in the liquid return chamber 31, the elastic structure 33 is in a natural state. When the magnetorheological fluid in the elastic liquid storage capsule is pressed into the liquid return chamber 31, the magnetorheological fluid can drive the piston plate 32 to squeeze the elastic structure 33, and the elastic structure 33 can cause the piston plate 32 to reversely squeeze the magnetorheological fluid to produce a reflux trend through its own elastic restoring force, thereby increasing the damping effect. Therefore, the piston plate 32 can make the volume of the liquid return chamber 31 adaptive, and the elastic structure 33 can limit the flow of the magnetorheological fluid. The elastic structure 33 is preferably, but not limited to, a spring or an elastic band.

[0077] The diameter of the liquid through hole 114 is relatively small, which can increase the resistance encountered by the magnetorheological fluid in the process of entering the liquid return chamber 31 , and further enhance the damping effect of the gap plugging device 100 .

[0078] Preferably, the electromagnetic component is disposed around the liquid hole 114, and by adjusting the magnetic field in the liquid hole 114, the viscosity of the magnetorheological fluid at the liquid hole 114 can be quickly changed, thereby quickly adjusting the damping force of the gap plugging device 100.

[0079] Preferably, in this embodiment, the liquid return structure also includes an adjusting rod 34 and a driving mechanism 35. Among them, the adjusting rod 34 is inserted into the second chamber of the liquid return tank 31 on one side of the first side plate 11. An air vent suitable for connecting the second chamber with the outside is formed on the adjusting rod 34. The driving mechanism 35 is connected to the adjusting rod 34 and is suitable for driving the adjusting rod 34 to move closer to or away from the first chamber. When the node is subjected to force and causes the gap to twist or displace and deform, the operator can start the driving mechanism 35 to move the adjusting rod 34 toward the direction of the piston plate 32, so that the piston plate 32 compresses the magnetorheological fluid to flow back to the elastic liquid storage bag, and the elastic liquid storage bag is hydraulically expanded, and the supporting top beam node is reset. Except for the support top reset operation, the adjusting rod 34 is set to be away from the piston plate 32 to ensure that the adjusting rod 34 does not interfere with the working effect of the gap plugging device 100.

[0080] The driving mechanism 35 may be a linear driving mechanism 35 directly connected to the piston plate 32, or may be a rotation source. For example, in the present embodiment, the driving mechanism 35 is a rotation source, and the rotation source is fixedly arranged on the side where the adjusting rod 34 is inserted into the first side plate 11. Preferably, the rotation source is a hollow shaft motor. An internal thread is arranged at the hollow shaft of the motor, and the adjusting rod 34 is inserted into the internal thread and is formed with an external thread that matches the internal thread. The length of the adjusting rod 34 is preferably greater than the depth of the liquid return tank 31.

[0081] Preferably, in this embodiment, an elastic liquid storage bag limiting groove 113 is formed on the side of the first side plate 11 facing the second side plate 12, which can restrict the sliding range of the elastic liquid storage bag on the first side plate 11 and prevent the elastic liquid storage bag from detaching from the first side plate 11.

[0082] The magnetic force of the electromagnetic component can be adjusted manually. Preferably, in this embodiment, the gap plugging device 100 further includes an acceleration detection module 7 and a control module. The acceleration detection module 7 is suitable for detecting the acceleration value of the environment in which the gap plugging device 100 is located. The control module is connected to the acceleration detection module 7 and the electromagnetic component in communication, and is suitable for controlling the electromagnetic component to adjust the viscosity of the magnetorheological fluid according to the detection result of the acceleration detection module 7.

[0083] For example, when the acceleration detection module 7 detects that the environmental vibration exceeds the acceleration threshold, it can trigger the magnetism of the electromagnetic component to increase, resulting in a decrease in the passing capacity of the magnetorheological fluid at the liquid passage hole 114, thereby increasing the damping provided by the elastic liquid storage capsule. Therefore, the damping effect of the elastic liquid storage capsule of the gap plugging device 100 of this embodiment can be automatically adjusted, and has good adaptability to the environment.

[0084] The acceleration detection module 7 may optionally include an acceleration sensor disposed between the first side plate 11 and the second side plate 12. Preferably, in order to make the acquisition result of the acceleration sensor more comprehensive and accurate, in this embodiment, the acceleration detection module 7 includes a first acceleration sensor, a second acceleration sensor and a third acceleration sensor. The first acceleration sensor is disposed on one of the first side plate 11 and the second side plate 12, and faces the other of the first side plate 11 and the second side plate 12.

[0085] The second acceleration sensor is disposed on one of the first side plate 11 and the second side plate 12, and is disposed toward the embedding direction of the gap plugging device 100, and is perpendicular to the orientation of the first acceleration sensor. The third acceleration sensor is disposed on one of the first side plate 11 and the second side plate 12, and is perpendicular to the orientation of the first acceleration sensor and the second acceleration sensor. For example, in this embodiment, the first acceleration sensor is disposed on the first side plate 11 and is disposed toward the second side plate 12. The second acceleration sensor is disposed on the first side plate 11. The third acceleration sensor is disposed on the first side plate 11.

[0086] Preferably, in order to prevent the first side plate 11 and the second side plate 12 of the gap plugging device 100 from deflecting under the action of external force, resulting in an inability to fit tightly with the gap, in this embodiment, the gap plugging device 100 also includes at least one group of first tensioning mechanisms 41, at least two first shape memory alloy wires 43, at least one group of second tensioning mechanisms 42 and at least two second shape memory alloy wires 45.

[0087] like Figure 7 , Figure 8 and Fig. 9 As shown, each group of first tensioning mechanisms 41 includes two first tensioning mechanisms 41 symmetrically distributed on the first end of the first side plate 11. The first side plate 11 is formed with first alloy wire holes 421 corresponding to the number of the first tensioning mechanisms 41. The first end of the first alloy wire hole 421 is located on a side of the first side plate 11 close to the second side plate 12, and is arranged at the second end of the first side plate 11, and the second end of the first alloy wire hole 411 extends to the first tensioning mechanism 41.

[0088] The first end of each first shape memory alloy wire 43 is fixedly connected to the second side plate 12 . The first shape memory alloy wire 43 passes through a first alloy wire hole 421 and the second end is connected to the first tensioning mechanism 41 .

[0089] like Fig.10As shown, each group of second tensioning mechanisms 42 includes two second tensioning mechanisms 42 symmetrically distributed on the first end of the second side plate 12. The second side plate 12 is formed with second alloy wire holes 422 corresponding to the number of the second tensioning mechanisms 42. The first end of the second alloy wire hole 422 is located on a side of the second side plate 12 close to the elastic liquid storage bag, and is arranged close to the second end of the second side plate 12, and the second end of the second alloy wire hole 422 extends to the second tensioning mechanism 42.

[0090] At least two second shape memory alloy wires 45 , each second shape memory alloy wire 45 has a first end fixedly connected to the first side plate 11 , and the second shape memory alloy wire 45 passes through a second alloy wire hole 422 and has a second end connected to the second tensioning mechanism 42 .

[0091] Therefore, at least two first shape memory alloy wires 43 and at least two second shape memory alloy wires 45 can cause the first side plate 11 and the second side plate 12 to move closer together, and the elastic liquid storage bag can rely on its own supporting force and damping force to prevent the first side plate 11 and the second side plate 12 from moving closer together. The first side plate 11 and the second side plate 12 can remain relatively stable under the supporting force of the elastic liquid storage bag and the tensioning force of the first shape memory alloy wire 43 and the second shape memory alloy wire 45.

[0092] Furthermore, since the first shape memory alloy wire 43 and the second shape memory alloy wire 45 can be tensioned from the four corners of the first side panel 11 and the second side panel 12 respectively, the tension provided by them can ensure that the first side panel 11 and the second side panel 12 are in a stable state. When the gap at the beam-column node continues to open and close irregularly and repeatedly as the earthquake continues, the first shape memory alloy wire 43 and the second shape memory alloy wire 45 can be stretched and rely on their own tensioning performance to achieve a follow-up adjustment effect during the earthquake, thereby avoiding the formation of gaps between the gap plugging device 100 and the side walls of the gap, and avoiding the gap plugging device 100 from escaping from the gap.

[0093] The first tensioning mechanism 41 may be optionally formed at the end of the first side plate 11 along the length direction, or may be optionally formed on a side of the first side plate 11 close to the second side plate 12, that is, one side along the thickness direction, or may be optionally formed inside the first side plate 11 and partially exposed from one side or end of the first side plate 11, wherein the end refers to one end of the first side plate 11 along the length direction, and the side wall refers to the side of the first side plate 11 along the thickness direction.

[0094] Preferably, in this embodiment, a limiting hole 49 extending in the thickness direction is formed at the first end of the first side plate 11 and the second side plate 12, and the first tensioning mechanism 41 includes a winding post 46, a turbine 47 and a worm rod 48. The winding post 46 is rotatably inserted into the limiting hole 49, and the first shape memory alloy wire 43 is wound on the winding post 46. The turbine 47 is fixedly sleeved on the winding post 46. The worm rod 48 is rotatably arranged on the first side plate 11 and meshed with the turbine 47, and a handle is formed on the worm rod 48.

[0095] After the operator places the gap plugging device 100 into the gap of the beam-column node, the operator can rotate the worm by turning the handle, and drive the turbine 47 to rotate, so that the first shape memory alloy wire 43 is wound around the winding column 46 to put the first shape memory alloy wire 43 in a tensioned state, ensuring that the first side plate 11 and the second side plate 12 can be reliably constrained at an angle that matches the side walls of the gap.

[0096] The second tensioning mechanism 42 includes a winding post 46, a turbine 47 and a worm rod 48. The winding post 46 is rotatably inserted into the limiting hole 49, and the second shape memory alloy wire 45 is wound around the winding post 46. The turbine 47 is sleeved on the winding post 46. The worm rod 48 is rotatably arranged on the second side plate 12 and meshed with the turbine 47. A handle is formed on the worm rod 48.

[0097] After the operator places the gap plugging device 100 into the gap of the beam-column node, the operator can rotate the worm by turning the handle, and drive the turbine 47 to rotate, so that the second shape memory alloy wire 45 is wound around the winding column 46 to put the second shape memory alloy wire 45 in a tensioned state, ensuring that the first side plate 11 and the second side plate 12 can be reliably constrained at an angle that matches the side walls of the gap.

[0098] In order to provide a monitoring means for the disengagement amount of the beam-column node, preferably, in this embodiment, the damping gap plugging device 100 also includes a transmitter 61 and a receiver 62.

[0099] The transmitter 61 is fixedly arranged on one of the first side plate 11 and the second side plate 12. The receiver 62 is fixedly arranged on the other of the first side plate 11 and the second side plate 12, and is arranged opposite to the transmitter 61, and is suitable for receiving the signal emitted by the transmitter 61. After the damping gap plugging device 100 is embedded in the gap, the current position of the transmitter 61 on the receiver 62 is recorded as the initial value of the node deformation monitoring. When the node is subjected to force and the shape changes, the displacement trajectory and the monitoring final value of the laser signal emitted by the transmitter 61 on the receiver 62 can be recorded, and the difference between the monitoring final value and the monitoring initial value is the displacement of the node.

[0100] The number of transmitters 61 and receivers 62 can be selected as one group or multiple groups. Preferably, in this embodiment, in order to avoid inaccurate detection results of node deformation due to flipping of the first side panel 11 or the second side panel 12, the number of transmitters 61 and receivers 62 is four respectively, and the four transmitters 61 are respectively arranged at the four corners of the first side panel 11, and the four receivers 62 are respectively arranged at the four corners of the second side panel 12, so as to perform more accurate detection of the node disengagement amount.

[0101] Next, the method for using the gap plugging device 100 according to the embodiment of the present invention is described:

[0102] Step 1: Adjust the first side plate 11 and the second side plate 12 so that they are opposite to each other, adjust the distance between the first side plate 11 and the second side plate 12 according to the width of the gap, make the total thickness of the gap plugging device 100 slightly smaller than the total width of the gap, and the elastic liquid storage bag is compressed to a certain extent.

[0103] Step 2: embed the compressed device into the gap, and relax the gap plugging device 100, so that the compression of the elastic liquid storage bag is partially released, thereby supporting the first side plate 11 and the second side plate 12 to contact the side wall of the gap.

[0104] Step 3: Rotate the handle to tension the first shape memory alloy wire 43 and the second shape memory alloy wire 45 to a limit that does not cause new deformation of the elastic liquid storage bag.

[0105] Step 4: Make the laser generator emit laser to record the initial position of the light spot on the laser receiving plate as the initial value for monitoring the deformation of the beam-column node. When the beam-column node is subjected to force and its shape changes, make the laser generator emit laser again and the position of the light spot on the laser receiving plate changes. The position of the light spot after displacement can also be recorded. The difference between the final monitoring value and the initial monitoring value is the node displacement.

[0106] Step 5: When the node is subjected to force, causing the gap to twist or displace, the operator can start the driving mechanism 35 to move the adjusting rod 34 toward the piston plate 32, so that the piston plate 32 compresses the magnetorheological fluid to flow back to the elastic fluid storage bag. The elastic fluid storage bag is hydraulically expanded, and the supporting beam-column node is reset.

[0107] To sum up, the gap plugging device 100 of this embodiment can overcome the defect that the gap plugging device 100 in the prior art cannot prevent the node from falling out. It can prevent the node from falling out and provide a monitoring means for the node's falling out amount, and can provide a resetting means for the deformed node.

[0108] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
