When the configuration changes at the node, the first damper, the second damper and the third damper can be compressed or stretched, and cooperate with the second friction structure to restrain the movement speed of the node in two directions in the plane during the process of the node slipping out. Therefore, a resistance to prevent the node from slipping out can be generated, and the effect of preventing the node from slipping out can be achieved. The three-way damping gap plugging device of the present invention can prevent the three-way damping gap plugging device from slipping, and further prevent the beam-column node from slipping out by means of the damping force of the three-way damping gap plugging device itself.

Description

Technical Field

[0001] The present invention relates to the technical field of building structure reinforcement, and particularly relates to a three-way damping gap plugging device with a retaining plate. Background Art

[0002] In traditional and modern buildings and structures, gaps frequently appear between different components due to reasons such as manufacturing errors and installation process requirements. Taking traditional wooden structure buildings as an example, there are often top wall and side wall gaps at beam-column joints. Working with gaps has become a common working state of structural components. During the long service life cycle, self-weight, seismic loads, etc. will increase the gaps; the influence of environmental factors on materials will also cause the gaps at beam-column joints to increase. If the gaps are large, it will lead to loose connections of components, resulting in horizontal swinging or even torsion of components during an earthquake, which is extremely unfavorable for building earthquake resistance.

[0003] The prior art discloses a longitudinal gap plugging device, including: a first panel, on which a plurality of guide seats are provided; a second panel, disposed opposite to the first panel; a stranded wire, wound around the guide seats, a first end of the stranded wire is connected with a stranded wire end seat, the stranded wire end seat is fixedly connected with the second panel, a second end of the stranded wire extends out of the space between the second panel and the first panel and is connected with a fastening device, the fastening device can tighten and release the stranded wire; four groups of elastic components are provided, the elastic components are disposed between the first panel and the second panel and are respectively close to the corners of the second panel, and a first end of the elastic component is fixedly connected with the first panel, a second end of the elastic component is fixedly connected with the second panel; two groups of air columns are provided, the connection line of one group of air columns intersects with the connection line of the other group of air columns to form a cross, each group of air columns includes two air columns, a first panel is provided with an air duct corresponding to each air column and an air groove communicated with a first end of the air duct, the air column is an elastic hollow column body with an opening at the first end and a closed second end, the first panel is provided with a first limiting groove 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, a second end of the air duct is provided with an air nozzle, and the air nozzle is connected with a pressure gauge.

[0004] The above prior art can achieve the function of gap plugging. However, during an earthquake, the gap will open and close repeatedly and irregularly with the continuous occurrence of the earthquake, resulting in changes in the size of the gap during the earthquake. The originally firmly plugged gap plugging device is very likely to fall off due to the widening of the gap, resulting in the loss of the gap plugging effect and being unable to prevent the beam-column joint from coming out. Summary of the Invention

[0050] The present invention has the following advantages:

[0051] The three-way damping gap plugging device with a retaining plate of the present invention mainly includes a first side plate, a second side plate, a first damper, a second damper, a third damper, a slider, a first retaining plate and a second retaining plate. The operator can adjust the first side plate and the second side plate to make the first side plate and the second side plate face each other, and adjust the slider to make its position in the second groove section as centered as possible. Then, according to the width of the gap, adjust the distance between the first side plate and the second side plate so that the total thickness of the gap plugging device is slightly less than the total width of the gap. At this time, the first damper is in a compressed state due to the adjustment of the distance between the first side plate and the second side plate. Then embed the gap plugging device into the gap and relax the gap plugging device. The first damper can extend through its own elastic restoring force so that the first side plate and the second side plate are respectively in close contact with the side walls of the gap.

[0052] Therefore, the three-way damping gap plugging device with a retaining plate of the present invention is in a compressed state when embedded in the gap. When the gap vibrates, it can adjust its own opening degree with the opening and closing of the gap by using its own elastic restoring force, thereby avoiding the generation of gaps between the three-way damping gap plugging device and the side walls of the gap, resulting in the slippage of the three-way damping gap plugging device.

[0053] In addition, the anti-slip protrusions of the first anti-displacement plate and the second anti-displacement plate can closely cooperate with the side walls of the gap, thereby preventing the three-way damping gap plugging device from disengaging from the beam-column joint, and increasing the applicability of the three-way damping gap plugging device to the side wall surface of the gap with unevenness. On this basis, when the configuration changes at the joint, the first damper is subjected to an external force and expands or contracts, thereby providing a resistance along the length direction of the first damper. The first side plate and the second side plate relatively displace with the tendency of the beam to disengage. At this time, driven by the hinged end of the first damper, the slider relatively displaces with respect to the first side plate, so that the second damper and the third damper can be compressed or stretched, and in cooperation with the first friction structure and the second friction structure, the movement rates in two directions in the plane during the disengagement of the joint can be restricted. Therefore, the three-way damping gap plugging device of this embodiment can also generate a resistance to prevent the joint from disengaging, thereby enhancing the anti-impact performance of the joint, preventing the side walls of the gap from moving relative to each other, and achieving the effect of preventing the joint from disengaging.

[0054] In summary, the three-way damping gap plugging device with an anti-displacement plate of the present invention can overcome the defect that the existing three-way damping gap plugging device is prone to fall off from the gap when the gap vibrates, thereby providing a three-way damping gap plugging device that can autonomously adjust its own opening degree with the opening and closing of the gap, which can prevent the three-way damping gap plugging device from slipping, and further prevent the beam-column joint from disengaging by means of the damping force of the three-way damping gap plugging device itself.

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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0070] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0071] As Figure 1 and Figure 2 As shown, this embodiment relates to a three-way damping gap plugging device 100 with a retaining plate, including a first side plate 11, a second side plate 12, a first damper 3a, a slider 34, a second damper 3b, a third damper 3c, a first retaining plate 51 and a second retaining plate 52. Among them, the first side plate 11 and the second side plate 12 are arranged opposite to each other. A receiving groove 13 is formed on the side of the first side plate 11 opposite to the second side plate 12. The receiving groove 13 is successively formed with a first groove section 131 and a second groove section 132 along its depth direction. The cross-sectional area of the first groove section 131 is smaller than that of the second groove section 132.

[0072] The first damper 3a is arranged between the first side plate 11 and the second side plate 12, and the first end is fixedly connected to the second side plate 12, and is adapted to provide resistance along its length direction.

[0073] The slider 34 is adapted to slide in the second groove section 132 of the first side plate 11. The first end of the first damper 3a passes through the first groove section 131 of the receiving groove 13 and is hinged to the slider 34. The area of the slider 34 is larger than that of the first groove section 131. A first friction structure is arranged between the first damper 3a and the slider 34. A second friction structure is arranged between the slider 34 and the first side plate 11.

[0074] The bodies of the second damper 3b and the third damper 3c are both connected to the first side plate 11. The pistons 32 of the second damper 3b and the third damper 3c are both connected to the slider 34. An included angle is formed between the telescopic directions of the pistons 32 of the second damper 3b and the third damper 3c.

[0075] The three-way damping gap plugging device 100 with anti-disengagement plates of this embodiment mainly includes a first side plate 11, a second side plate 12, a first damper 3a, a second damper 3b, a third damper 3c, a slider 34, a first anti-disengagement plate 51, and a second anti-disengagement plate 52. The operator can adjust the first side plate 11 and the second side plate 12 to make the first side plate 11 and the second side plate 12 face each other, and adjust the slider 34 to make its position in the second groove section 132 as centered as possible. Then, according to the width of the gap, adjust the distance between the first side plate 11 and the second side plate 12 to make the total thickness of the gap plugging device 100 slightly less than the total width of the gap. At this time, the first damper 3a is in a compressed state due to the adjustment of the distance between the first side plate 11 and the second side plate 12. Then, embed the gap plugging device 100 into the gap and relax the gap plugging device 100. The first damper 3a can extend through its own elastic restoring force so that the first side plate 11 and the second side plate 12 are respectively in close contact with the side walls of the gap.

[0076] Therefore, the three-way damping gap plugging device 100 with anti-disengagement plates of this embodiment is in a compressed state when being embedded into the gap. When the gap vibrates, it can utilize its own elastic restoring force to adjust its own opening degree along with the opening and closing of the gap, thereby avoiding the generation of gaps between the three-way damping gap plugging device 100 and the side walls of the gap, resulting in the disengagement of the three-way damping gap plugging device 100.

[0077] In addition, the anti-slip protrusions 53 of the first anti-disengagement plate 51 and the second anti-disengagement plate 52 can be closely matched with the side walls of the gap, thereby preventing the three-way damping gap plugging device 100 from disengaging from the beam-column joint and increasing the applicability of the three-way damping gap plugging device 100 to the side walls of the gap with concave-convex surfaces. On this basis, when the configuration change occurs at the joint, the first damper 3a is stretched or compressed under the action of an external force, thereby providing a resistance along the length direction of the first damper 3a. The first side plate 11 and the second side plate 12 relatively displace along with the disengagement trend of the beam. At this time, driven by the hinged end of the first damper 3a, the slider 34 relatively displaces with respect to the first side plate 11 so that the second damper 3b and the third damper 3c can be compressed or stretched, and in cooperation with the first friction structure and the second friction structure, the movement speeds in two directions in the plane during the disengagement process of the joint can be restricted. Therefore, the three-way damping gap plugging device 100 of this embodiment can also generate a resistance to prevent the disengagement of the joint, thereby improving the anti-impact performance of the joint, preventing the crosstalk between different side walls of the gap, and achieving the effect of preventing the disengagement of the joint.

[0078] In summary, the three-way damping gap plugging device 100 with a retaining plate in this embodiment can overcome the defect that the existing three-way damping gap plugging device 100 is prone to fall off from the gap when the gap vibrates, thereby providing a three-way damping gap plugging device 100 that can autonomously adjust its own opening degree along with the opening and closing of the gap. It can prevent the three-way damping gap plugging device 100 from slipping off, and then prevent the beam-column joint from disengaging by means of the damping force of the three-way damping gap plugging device 100 itself.

[0079] The first friction structure can be preferably a damping hinge connected between the first damper 3a and the slider 34. In this embodiment, the first damping structure includes a friction ball and a ball hinge bowl. The friction ball is formed at the first end of the first damper 3a. The ball hinge bowl is formed on the side of the slider 34 close to the first damper 3a. The friction ball is limited in the ball hinge bowl and can rotate relative to the ball hinge bowl. At the same time, a resistance that hinders the rotation of the first damper 3a can be generated on the contact surface between the friction ball and the ball hinge bowl. A damping layer is formed on at least one of the friction ball and the ball hinge bowl, which can increase the maximum static friction between the friction ball and the ball hinge bowl. The damping layer can be preferably a frosted surface formed on the friction ball or the ball hinge bowl, or an anti-slip material sandwiched between the friction ball and the ball hinge bowl. In this embodiment, the damping layer is a friction anti-slip material coated on the friction ball or the ball hinge bowl.

[0080] In this embodiment, the telescopic directions of the second damper 3b and the third damper 3c can be parallel to the plane where the slider 34 is located, or form a certain angle with the plane where the slider 34 is located. Preferably, the telescopic directions of the second damper 3b and the third damper 3c are both set to be parallel to the slider 34, which can ensure that when the first side plate 11 and the second side plate 12 move relative to each other, the pistons 32 of the second damper 3b and the third damper 3c can perform telescopic movements and play a damping effect, and the second damper 3b and the third damper 3c do not interfere with each other during the movement process, and the movement range of the slider 34 is not likely to have dead corners.

[0081] The angle between the telescopic directions of the second damper 3b and the third damper 3c can be an acute angle, a right angle or an obtuse angle. Preferably, in this embodiment, the angle between the second damper 3b and the third damper 3c is a right angle.

[0082] The first side plate 11 can be optionally integrally formed. Preferably, in this embodiment, the first side plate 11 includes a base plate 111 and a friction plate 112 detachably connected to the base plate 111 on the side away from the damper. The second groove section 132 of the receiving groove 13 is formed between the base plate 111 and the friction plate 112. The second friction structure can be optionally a frosted surface formed in either the slider 34 or the friction plate 112, or can also be an anti-slip material clamped between the slider 34 and the friction plate 112. Preferably, in this embodiment, the second friction structure includes a damping anti-slip material coated on at least one of the slider 34 and the friction plate 112.

[0083] The first damper 3a is preferably but not limited to a liquid damper, a gas damper, an electromagnetic damper, etc. Preferably, as Figure 3 and Figure 4 shown, in this embodiment, the first damper 3a includes a cylinder block 31, a piston 32, a bottom support plate 33, and an electromagnetic assembly. Among them, a magnetorheological fluid is carried in the cylinder block 31. The piston 32 is movably inserted into the cylinder block 31 and divides a rod chamber and a rodless chamber in the cylinder block 31. A plurality of communication holes 322 communicating the rod chamber and the rodless chamber are formed on the piston head 321 of the piston 32. The bottom support plate 33 is slidably disposed in the rodless chamber and divides a magnetorheological fluid chamber and an air chamber in the rodless chamber, and a vent hole 311 is formed on the cylinder block 31 corresponding to the air chamber. The electromagnetic assembly is adapted to adjust the viscosity of the magnetorheological fluid.

[0084] When the first damper 3a is compressed, the piston 32 can move toward the rodless chamber. The magnetorheological fluid in the rodless chamber can enter the rod chamber through the communication holes 322 on the piston head 321 to shorten the overall length of the first damper 3a. As the piston rod of the piston enters the rod chamber, the air between the bottom support plate 33 and the cylinder block 31 is pressed out from the vent hole 311 to provide space for the piston rod to enter the cylinder block 31.

[0085] When the first damper 3a is stretched, the magnetorheological fluid in the rod chamber can enter the rodless chamber through the communication holes 322 on the piston head 321 to extend the overall length of the first damper 3a. As the piston rod is withdrawn from the cylinder block 31, air enters the air chamber through the vent hole 311, and the volume of the air chamber increases, so that the piston rod can be smoothly withdrawn.

[0086] By using the electromagnetic assembly to adjust the viscosity of the magnetorheological fluid, the passing ability of the magnetorheological fluid at the communication holes 322 can be changed, thereby adjusting the power of the first damper 3a. For example, when the magnetism is enhanced, the passing ability of the magnetorheological fluid at the through holes is weakened, and the power of the first damper 3a increases.

[0087] The second damper 3b is preferably but not limited to a liquid damper, a gas damper, an electromagnetic damper, etc. Preferably, in this embodiment, the second damper 3b includes a cylinder block 31, a piston 32, a bottom support plate 33, and an electromagnetic assembly. The cylinder block 31 contains magnetorheological fluid. The piston 32 is movably inserted into the cylinder block 31 and divides the cylinder block 31 into a rod chamber and a rodless chamber. A plurality of communication holes 322 communicating the rod chamber and the rodless chamber are formed on the piston head 321 of the piston 32. The bottom support plate 33 is slidably disposed in the rodless chamber and divides the rodless chamber into a magnetorheological fluid chamber and an air chamber. A ventilation hole 311 is formed on the cylinder block 31 corresponding to the air chamber. The electromagnetic assembly is adapted to adjust the viscosity of the magnetorheological fluid.

[0088] When the second damper 3b is compressed, the piston 32 can move toward the rodless chamber. The magnetorheological fluid in the rodless chamber can enter the rod chamber through the communication holes 322 on the piston head 321 to shorten the overall length of the second damper 3b. As the piston rod enters the rod chamber, the air in the air chamber flows out through the ventilation hole 311, and the volume of the air chamber decreases, so as to provide space for the piston rod to enter the cylinder block 31.

[0089] When the second damper 3b is stretched, the magnetorheological fluid in the rod chamber can enter the rodless chamber through the communication holes 322 on the piston head 321 to extend the overall length of the second damper 3b. As the piston rod is withdrawn from the cylinder block 31, air enters the air chamber through the ventilation hole 311, and the volume of the air chamber increases, so that the piston rod can be smoothly withdrawn.

[0090] By using the electromagnetic assembly to adjust the viscosity of the magnetorheological fluid, the passing ability of the magnetorheological fluid at the communication holes 322 can be changed, thereby adjusting the power of the damper. For example, when the magnetism is enhanced, the passing ability of the magnetorheological fluid at the through holes is weakened, and the power of the damper increases.

[0091] The third damper 3c is preferably but not limited to a liquid damper, a gas damper, an electromagnetic damper, etc. Preferably, in this embodiment, the third damper 3c includes a cylinder block 31, a piston 32, a bottom support plate 33, and an electromagnetic assembly. The cylinder block 31 contains magnetorheological fluid. The piston 32 is movably inserted into the cylinder block 31 and divides the cylinder block 31 into a rod chamber and a rodless chamber. A plurality of communication holes 322 communicating the rod chamber and the rodless chamber are formed on the piston head 321 of the piston 32. The bottom support plate 33 is slidably disposed in the rodless chamber and divides the rodless chamber into a magnetorheological fluid chamber and an air chamber. A ventilation hole 311 is formed on the cylinder block 31 corresponding to the air chamber. The electromagnetic assembly is adapted to adjust the viscosity of the magnetorheological fluid.

[0092] When the third damper 3c is compressed, the piston 32 can move towards the rodless cavity. The magnetorheological fluid in the rodless cavity can enter the rod cavity through the communication hole 322 on the piston head 321 to shorten the overall length of the third damper 3c. As the piston rod enters the rod cavity, the air in the air cavity flows out through the ventilation hole 311, and the volume of the air cavity decreases, thereby providing space for the piston rod to enter the cylinder block 31.

[0093] When the third damper 3c is stretched, the magnetorheological fluid in the rod cavity can enter the rodless cavity through the communication hole 322 on the piston head 321 to extend the overall length of the third damper 3c. As the piston rod is withdrawn from the cylinder block 31, air enters the air cavity through the ventilation hole 311, and the volume of the air cavity increases, so that the piston rod can be smoothly withdrawn.

[0094] By using the electromagnetic component to adjust the viscosity of the magnetorheological fluid, the passing ability of the magnetorheological fluid at the communication hole 322 can be changed, thereby adjusting the power of the third damper 3c. For example, when the magnetism is enhanced, the passing ability of the magnetorheological fluid at the through hole is weakened, and the power of the third damper 3c increases.

[0095] Preferably, in this embodiment, a first elastic member 38 is formed in the rod cavity and is connected between one end of the cylinder block 31 and the piston head 321, and the first elastic member 38 is in a stretched state. When the three-way damping gap plugging device 100 is embedded into the gap, the piston rod can extend into the cylinder block 31, so that the first elastic member 38 is stretched, thereby generating a force to prevent the first side plate 11 and the second side plate 12 from approaching each other, so that the first side plate 11 and the second side plate 12 are respectively in close contact with the side walls of the gap, and at the same time, the supporting force of the first damper 3a is enhanced, ensuring that one first damper 3a can support the first side plate 11 and the second side plate 12. When the side wall of the gap generates a configuration change, resulting in the damper being compressed, the piston rod can move towards the rodless cavity direction, and the first elastic member 38 can be further stretched, thereby providing a force to prevent the first side plate 11 and the second side plate 12 from approaching each other, thereby improving the damping effect of the damper. The first elastic member 38 is preferably but not limited to an elastic band or a spring, etc.

[0096] A second elastic member 39 is formed in the air cavity and is connected between the bottom support plate 33 and one end of the cylinder block 31. When the side wall of the gap generates a configuration change, resulting in the damper being compressed, the piston rod can move towards the rodless cavity direction, and the bottom support plate 33 can be compressed towards the direction away from the rodless cavity. The second elastic member 39 can be compressed, thereby providing damping to prevent the damper from being compressed, thereby improving the damping effect of the damper.

[0097] When the damper is stretched, the piston 32 can move in a direction away from the rodless chamber. The volume occupied by the piston rod in the cylinder block 31 decreases, and the bottom support plate 33 can move in a direction closer to the rodless chamber. The second elastic element can be stretched, thereby providing damping to prevent the damper from being stretched, thus improving the shock absorption effect of the damper. The second elastic member 39 is preferably but not limited to a spring or an elastic band, etc.

[0098] When the first elastic member 38 and the second elastic member 39 are provided in the first damper 3a, the damping effect of the first damper 3a can be improved to ensure that the first damper 3a can support the first side plate 11 and the second side plate 12; when the air chamber and the second elastic member 39 are provided, the volume of the damper itself can be effectively reduced.

[0099] Preferably, in this embodiment, the three-way damping gap plugging device 100 further includes an acceleration detection module and a control module. Among them, the acceleration detection module is adapted to detect the acceleration value of the environment where the gap plugging device 100 is located. The control module is communicatively connected to the acceleration detection module and the electromagnetic assembly, and is adapted to control the electromagnetic assembly to adjust the viscosity of the magnetorheological fluid according to the detection result of the acceleration detection module. For example, when the acceleration detection module detects that the vibration of the environment where the three-way damping gap plugging device 100 is located is small, the control electromagnetic assembly reduces the viscosity of the magnetorheological fluid.

[0100] For example, when the acceleration detection module detects that the environmental vibration exceeds the acceleration threshold, it can trigger an increase in the magnetism of the electromagnetic assembly, resulting in a weakened passing ability of the magnetorheological fluid at the communication hole 322 and enhancing the power of the damper. Therefore, the power of the damper of the three-way damping gap plugging device 100 in this embodiment can be automatically adjusted, and it has good adaptability to the environment.

[0101] The acceleration detection module can be selected to include an acceleration sensor provided 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 includes a first acceleration sensor 71, a second acceleration sensor 72, and a third acceleration sensor 73. Among them, the first acceleration sensor 71 is provided 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.

[0102] The second acceleration sensor 72 is provided on one of the first side plate 11 and the second side plate 12, and is arranged in the embedding direction of the three-way damping gap plugging device 100 and is perpendicular to the orientation of the first acceleration sensor. The third acceleration sensor 73 is provided on one of the first side plate 11 and the second side plate 12 and is perpendicular to the orientations of the first acceleration sensor 71 and the second acceleration sensor 72.

[0103] The control module can optionally be set to: be able to integrate the detection results of the first acceleration sensor 71, the second acceleration sensor, and the third acceleration sensor 73 to obtain the overall acceleration of the environment where the three-way damping gap plugging device 100 is located, and then control the electromagnetic component based on the overall acceleration. Preferably, the control module can also optionally be set to: be able to control the first damper 3a based on the detection result of the first acceleration sensor 71, control the second damper 3b based on the detection result of the second acceleration sensor 72, and control the third damper 3c based on the detection result of the third acceleration sensor 73. Thus, it is possible to perform targeted control on the dampers in three directions based on the accelerations in three directions of the three-way damping gap plugging device 100, the control is more precise, and the anti-impact performance of the node can be further improved.

[0104] In order to ensure that when the first side plate 11 and the second side plate 12 move relative to each other at various angles, the piston rods of the second damper 3b and the third damper 3c can adapt to the movement of the slider 34 and expand and contract to provide damping force. Preferably, in this embodiment, the second damper 3b and the third damper 3c are slidably arranged on the first side plate 11. The sliding direction of the second damper 3b forms an angle with the expansion and contraction direction of its piston 32. The third damper 3c is slidably arranged on the first side plate 11, and the sliding square of the third damper 3c forms an angle with the expansion and contraction direction of its piston 32. For example, in this embodiment, the angle between the sliding direction of the second damper 3b and the expansion and contraction direction of its piston 32 is a right angle. The angle between the sliding direction of the third damper 3c and the expansion and contraction direction of its piston 32 is a right angle.

[0105] As Figure 6 and Figure 7 shown, the second damper 3b and the first side plate 11 can optionally be connected by a guiding groove, or a guiding groove is formed on one of the second damper 3b and the first side plate 11, and a convex portion adapted to slide in the guiding groove is formed on the other. Preferably, in this embodiment, the three-way damping gap plugging device 100 further includes a fixing member 36. The second damper 3b is fixedly arranged in the fixing member 36. A receiving groove 13 adapted to match and receive the second damper 3b is formed on the fixing member 36. A guiding groove 113 is formed on the first side plate 11, and a convex portion adapted to slide in the guiding groove 113 is formed on the bottom of the fixing member 36. In order to prevent the fixing member 36 from disengaging from the first side plate 11. A T-shaped key 362 is provided on the bottom surface of the convex portion, and the cross-sectional shape of the T-shaped key 362 is the same as that of the guiding groove 113, so as to reliably limit the fixing member 36 in the guiding groove 113. When the node undergoes a configuration change, the main body of the second damper 3b and the second damper 3b can slide in the guiding groove 113, and the other end can maintain the same movement form as the slider 34.

[0106] The third damper 3c and the first side plate 11 can be optionally connected by a slide rail, or a guiding groove is formed on one of the third damper 3c and the first side plate 11, and a convex portion adapted to slide in the guiding groove is formed on the other. Preferably, in this embodiment, the three-way damping gap plugging device 100 further includes a fixing member 36. The third damper 3c is fixedly arranged in the fixing member 36. A receiving groove 13 adapted to receive the second damper 3b in a matching manner is formed on the fixing member 36. A guiding groove 113 is formed on the second side plate 12, and a convex portion adapted to slide in the guiding groove 113 is formed on the bottom of the fixing member 36. In order to prevent the fixing member 36 from disengaging from the first side plate 11, a T-shaped key 362 is provided on the bottom surface of the convex portion, and the cross-sectional shape of the T-shaped key 362 is the same as that of the guiding groove 113, so as to reliably limit the fixing member 36 in the guiding groove 113.

[0107] Preferably, in order to prevent the first side plate 11 and the second side plate 12 of the three-way damping gap plugging device 100 from deflecting under an external force, resulting in an inability to closely cooperate with the gap, in this embodiment, the three-way damping gap plugging device 100 further includes at least one set of first tensioning mechanisms 41, at least two first shape memory alloy wires 43, at least one set of second tensioning mechanisms 42, and at least two second shape memory alloy wires 45.

[0108] Wherein, as Figure 5 、 Figure 8 and Figure 9 shown, each set of first tensioning mechanisms 41 includes two first tensioning mechanisms 41 symmetrically distributed on the first end of the first side plate 11. First alloy wire holes 421 corresponding to the number of the first tensioning mechanisms 41 are formed in the first side plate 11. The first end of the first alloy wire hole 421 is located on the side of the first side plate 11 close to the second side plate 12 and is arranged near 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.

[0109] The first end of each first shape memory alloy wire 43 is fixedly connected to the second side plate 12. Each 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.

[0110] Each set of second tensioning mechanisms 42 includes two second tensioning mechanisms 42 symmetrically distributed on the first end of the second side plate 12. Second alloy wire holes 422 corresponding to the number of the second tensioning mechanisms 42 are formed on the second side plate 12. The first end of the second alloy wire hole 422 is located on the side of the first side plate 11 close to the first damper 3a and is arranged near 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.

[0111] At least two second shape memory alloy wires 45, with the first end of each second shape memory alloy wire 45 fixedly connected to the first side plate 11, and each second shape memory alloy wire 45 passing through a second alloy wire hole 422 and the second end being connected to the second tensioning mechanism 42.

[0112] 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 approach each other, and the first damper 3a can rely on its own supporting force and damping force to prevent the first side plate 11 and the second side plate 12 from approaching or separating, and the first side plate 11 and the second side plate 12 can remain relatively stable under the action of the supporting force of the first damper 3a and the tensile forces of the first shape memory alloy wires 43 and the second shape memory alloy wires 45.

[0113] Also, since the first shape memory alloy wires 43 and the second shape memory alloy wires 45 can be tensioned from the four corners of the first side plate 11 and the second side plate 12 respectively, the provided tensile forces can ensure that the first side plate 11 and the second side plate 12 are in a stable state. When the gap of the beam-column joint repeatedly opens and closes irregularly with the continuous occurrence of an earthquake, the first shape memory alloy wires 43 and the second shape memory alloy wires 45 can be stretched, and rely on their own tensile properties to achieve a follow-up adjustment effect during the earthquake, avoiding the appearance of gaps between the three-way damping gap plugging device 100 and the side walls of the gap, and avoiding the three-way damping gap plugging device 100 from coming out of the gap.

[0114] The first tensioning mechanism 41 can be optionally formed at the end of the first side plate 11, or can be selected to be formed on the side of the first side plate 11 close to the second side plate 12, or can also be partially formed inside the first side plate 11. Preferably, in this embodiment, a limiting hole 49 extending along its thickness direction is formed at the first ends 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 48. Among them, the winding post 46 is rotatably inserted at the limiting hole 49, and the first shape memory alloy wire 43 is wound around the winding post 46. The turbine 47 is fixedly sleeved on the winding post 46. The worm 48 is rotatably arranged on the first side plate 11 and meshes with the turbine 47, and a handle is formed on the worm 48.

[0115] After the operator places the gap plugging device 100 into the gap of the beam-column joint, the operator can rotate the handle to make the worm rotate, and drive the turbine 47 to rotate, so that the first shape memory alloy wire 43 is wound around the winding post 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 matching the side walls of the gap.

[0116] The second tensioning mechanism 42 includes a wire winding column 46, a turbine 47, and a worm 48. Among them, the wire winding column 46 is rotatably inserted into the limit hole 49, and the second shape memory alloy wire 45 is wound around the wire winding column 46. The turbine 47 is sleeved on the wire winding column 46. The worm 48 is rotatably arranged on the second side plate 12 and meshes with the turbine 47, and a handle is formed on the worm 48.

[0117] After the operator places the gap plugging device 100 into the gap of the beam-column joint, the operator can rotate the handle to rotate the worm, and drive the turbine 47 to rotate, so that the second shape memory alloy wire 45 is wound around the wire 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 matching the side wall of the gap.

[0118] To provide a monitoring means for the displacement of the beam-column joint, preferably, in this embodiment, the three-way damping gap plugging device 100 further includes a transmitter 61 and a receiver 62.

[0119] 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 adapted to receive the signal emitted by the transmitter 61. After the three-way damping gap plugging device 100 is embedded into 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 stressed and undergoes a configuration change, the displacement trajectory and the monitoring final value of the transmitter 61 on the receiver 62 can both be recorded, and the difference between the monitoring final value and the monitoring initial value is the displacement of the node.

[0120] The number of the transmitter 61 and the receiver 62 can be selected as one group or multiple groups. Preferably, in this embodiment, in order to avoid inaccurate detection results of the node deformation caused by the flipping of the first side plate 11 or the second side plate 12, the number of the transmitter 61 and the receiver is four respectively. The four transmitters 61 are respectively arranged at the four corners of the second side plate 12, and the four receivers 62 are respectively arranged at the four corners of the first side plate 11, which can more accurately detect the node displacement.

[0121] Next, the usage method of the three-way damping gap plugging device 100 according to the embodiment of the present invention will be described:

[0122] Step 1: 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 face each other, and adjust the position of the slider 34 in the receiving groove 13 to make its position in the receiving groove 13 as centered as possible.

[0123] Step 2: Adjust the distance between the first side plate 11 and the second side plate 12 according to the width of the gap, so that the thickness of the three-way damping gap plugging device 100 is slightly less than the total width of the gap. At this time, the first damper 3a is compressed to a certain extent.

[0124] Step 3: Embed the compressed device into the gap of the beam-column joint, and relax the three-way damping gap plugging device 100. The compression amount of the first damper 3a can be partially released, so that the first side plate 11 and the second side plate 12 are respectively abutted against the side walls of the gap.

[0125] Step 4: Rotate the handle to tension the first shape memory alloy wire 43 and the second shape memory alloy wire 45, with the limit that no new deformation is caused to the damper.

[0126] Step 5: Record the current position of the transmitter 61 on the receiver 62 as the initial value of the deformation monitoring of the beam-column joint. When the beam-column joint is stressed and undergoes a configuration change, the position of the transmitter 61 on the receiver 62 changes, the displacement trajectory of the transmitter 61 can be recorded, and the monitoring final value after displacement can also be recorded. The difference between the monitoring final value and the monitoring initial value is the joint displacement.

[0127] In summary, the three-way damping gap plugging device 100 with the transmitter 61 in this embodiment can overcome the defect that the three-way damping gap plugging device 100 in the prior art is prone to fall off from the gap when the gap vibrates, thereby providing a three-way damping gap plugging device 100 that can autonomously adjust its own opening degree as the gap opens and closes. It can prevent the three-way damping gap plugging device 100 from slipping off, and further prevent the beam-column joint from disengaging by means of the damping force of the three-way damping gap plugging device 100 itself, and can also provide a monitoring means for the joint disengagement amount.

[0128] Obviously, the above embodiments are only examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
