Description

Technical Field

[0001] The present invention relates to the technical field of beam-column connection nodes, and in particular to a beam-column connection node for assembled buildings. Background Art

[0002] In prefabricated steel frame structures, in addition to meeting basic bearing capacity requirements, the structure should also meet the principles of "strong shear and weak bending", "strong columns and weak beams" and "strong nodes and weak components" in seismic design to achieve the seismic fortification goal of "not being damaged by small earthquakes, being repairable by medium earthquakes and not collapsing by large earthquakes". The beam-column node area of ​​the prefabricated steel frame structure is of great significance to the overall bearing capacity and seismic performance of the structure, and is the key area where the entire structure is subjected to stress.

[0003] In order to improve the seismic resistance of the beam-column connection node, a damping mechanism is generally set at the node to dissipate energy and reduce vibration. However, during an earthquake, as the vibration continues, the temperature of the damping fluid continues to increase. The viscosity of the damping fluid will be affected by the temperature. When the temperature rises, the viscosity of the damping fluid will decrease, which will in turn weaken the damping effect of the damping mechanism. Summary of the invention

[0033] 1. The present invention is provided with a first damping hole. Since the line connecting the centers of the two end openings of the first damping hole is inclined to the axis of the piston, the damping fluid can flow between the first area and the second area along the direction inclined to the axis of the piston, so that the damping fluid after absorbing heat can be dispersed in the damping fluid in the first area and the second area along the radial direction of the piston, thereby improving the temperature uniformity of the damping fluid and avoiding poor heat dissipation effect of the damping fluid caused by excessively high temperature of the local damping fluid.

When encountering a low-magnitude earthquake, the exhaust ring moves a small distance, and the exhaust ring cannot exert a force on the first heat-conducting ring. At this time, the spring clip is in a concentrated state. At this time, the spring clip is relative to the heat dissipation fins in the form of increasing the contact area to accelerate heat dissipation. When encountering a medium-to-high-magnitude earthquake, the exhaust ring moves a longer distance, and the exhaust ring is pressed down onto the first heat-conducting ring. Since one end of the spring clip is fixedly connected to the second heat-conducting ring, the inclination angle of the spring clip increases. At this time, the spring clip switches from a concentrated state to a dispersed state. In this way, the spring clip switches back and forth between the dispersed state and the concentrated state, which not only plays a role of elastic shock absorption, but also plays a role of diversion through the change in the angle of the spring clip, thereby accelerating the discharge of heat in the air-cooled heat dissipation cavity to the outside and improving the heat exchange efficiency.

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0052] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0053] like Figure 1-Figure 13 As shown, a beam-column connection node for an assembled building includes a steel column 100, a cross beam 200 and a damping assembly 300, wherein the steel column 100 is vertically arranged, and the cross beam 200 is horizontally connected to the steel column 100, and the damping assembly 300 includes a connecting rod 310, a piston 320 and a damping cylinder 330, wherein one end of the connecting rod 310 is hinged to the steel column 100, and the other end of the connecting rod 310 is fixedly connected to the center of the piston 320, and the piston 320 is slidably connected in the damping cylinder 330, and the piston 320 divides the interior of the damping cylinder 330 from the outside to the inside into a first area 331 and a second area 332, and the first area 331 and the second area 332 are both filled with damping fluid, and the damping cylinder 330 is hinged to the cross beam 200 at one end away from the connecting rod 310, and the piston 320 is provided with a first damping fluid. The first damping hole 321 is close to the edge area of ​​the piston 320, the first damping hole 321 passes through the piston 320, and the line connecting the centers of the two end openings of the first damping hole 321 is inclined to the axis of the piston 320, and the first damping hole 321 is located in the first area 331. The end of the first damping hole 321 is provided with a first guide upper arc plate 3211, and the first guide upper arc plate 3211 is inclined to the axis of the piston 320 and also inclined along the circumference of the piston 320. The end of the first damping hole 321 located in the second area 332 is provided with a first guide lower arc plate 3212, and the first guide lower arc plate 3212 is inclined to the axis of the piston 320 and also inclined along the circumference of the piston 320. The inclination directions of the first guide lower arc plate 3212 and the first guide upper arc plate 3211 along the circumference of the piston 320 are opposite.

[0054] When encountering a low-magnitude earthquake, the steel column 100 swings slightly left and right. At this time, the piston 320 moves in a small range inside the damping cylinder 330. Since the first damping hole 321 is a through-hole structure, the damping fluid circulates through the first damping hole 321 between the first area 331 and the second area 332. At this time, the friction between the damping fluid and the first damping hole 321 makes the kinetic energy of the earthquake absorbed by the damping fluid, and the temperature of the damping fluid increases, thereby reducing the vibration amplitude of the steel column 100.

[0055] It is understandable that, since the line connecting the centers of the two end openings of the first damping hole 321 is inclined to the axis of the piston 320, the damping fluid can flow between the first region 331 and the second region 332 along the direction inclined to the axis of the piston 320, so that the damping fluid after absorbing heat can be dispersed in the damping fluid in the first region 331 and the second region 332 along the radial direction of the piston 320, thereby improving the temperature uniformity of the damping fluid and avoiding the poor heat dissipation effect of the damping fluid caused by the excessive temperature of the local damping fluid, so that the damping fluid can better absorb the kinetic energy generated by the earthquake. In addition, since the first damping hole 321 is inclined to the axis of the piston 320, when the damping fluid and the first damping hole 321 rub against each other, the friction heat absorption time is longer, and the piston 320 moves the same distance, and the damping fluid absorbs more heat, and the kinetic energy generated by the earthquake is better absorbed.

[0056] It can be understood that since the first guide upper arc plate 3211 is inclined to the axis of the piston 320 and inclined along the circumference of the piston 320, the first guide lower arc plate 3212 is inclined to the axis of the piston 320 and inclined along the circumference of the piston 320, and since the first guide lower arc plate 3212 and the first guide upper arc plate 3211 are inclined in opposite directions along the circumference of the piston 320, the damping fluid also rotates and flows inside the first area 331 and the second area 332 during the flow of the damping fluid along the radial direction of the piston 320. In this way, the heat of the damping fluid is dispersed through convection between the damping fluids, thereby further improving the uniformity of the damping fluid temperature.

[0057] It is understandable that, since the first damping hole 321 is close to the edge area of ​​the piston 320, the temperature in the damping fluid can be promptly transferred outward to the peripheral wall of the damping cylinder 330, so as to dissipate the heat in the damping fluid into the external air in a timely manner.

[0058] In a further embodiment, Figure 6 and Fig. 9 As shown, a second damping hole 322 is further provided on the piston 320, and the second damping hole 322 is located on the side of the first damping hole 321 close to the axis of the piston 320, the second damping hole 322 passes through the piston 320, and the line connecting the centers of the two end openings of the second damping hole 322 is inclined to the axis of the piston 320, the inclination direction of the first damping hole 321 is opposite to the inclination direction of the second damping hole 322, and a baffle 323 is rotatably connected in the second damping hole 322, the baffle 323 can block the second damping hole 322, and a torsion spring is provided at the rotation connection of the baffle 323, and when the baffle 323 rotates to open the second damping hole 322, the torsion spring is tightened to store force.

[0059] It should be added that if Fig. 9As shown, in order to ensure that the rotation direction of the baffle 323 when the damping fluid enters the second area 332 from the first area 331 is the same as the rotation direction of the baffle 323 when the damping fluid enters the first area 331 from the second area 332, a side plate 324 is also required to be provided on the peripheral wall of the second damping hole 322, so that the rotation of the baffle 323 is unidirectionally restricted by the side plate 324.

[0060] It should be added that the second damping hole 322 is an eccentric hole, so that the baffle 323 is subjected to unbalanced force when the damping fluid flows, and the baffle 323 is opened under the flow of the damping fluid.

[0061] When encountering a medium to high magnitude earthquake, the steel column 100 swings greatly and the frequency increases. At this time, the movement speed of the piston 320 becomes faster. At this time, as the piston 320 reciprocates, the baffle 323 is subjected to an increased force from the damping fluid. The force of the damping fluid on the baffle 323 overcomes the torsion force of the torsion spring and opens the second damping hole 322. This can speed up the energy consumption of the damping fluid and reduce the vibration amplitude of the steel column 100.

[0062] It is understandable that when a low-magnitude earthquake occurs, the movement speed of the piston 320 is slow, and the force of the damping fluid on the baffle 323 cannot overcome the torsion of the torsion spring to open the second damping hole 322. At this time, the second damping hole 322 is in a closed state. This is because if the second damping hole 322 is opened at this time, the friction force between the damping fluid and the first damping hole 321 and the second damping hole 322 will be greatly reduced, which is not conducive to energy consumption.

[0063] It can be understood that the inclination direction of the first damping hole 321 is opposite to the inclination direction of the second damping hole 322 in order to allow the damping fluid passing through the second damping hole 322 and the first damping hole 321 to be fully dispersed and mixed with other damping fluids in the first area 331 and the second area 332 in the radial direction, thereby improving the temperature uniformity of the damping fluid. Moreover, the convection of the damping fluid can further disperse the heat in the damping fluid, thereby also improving the temperature uniformity of the damping fluid.

[0064] In a further embodiment, Figure 6As shown, a second guide upper arc plate 3221 is provided at one end of the second damping hole 322 located in the first area 331, and the second guide upper arc plate 3221 is inclined to the axis of the piston 320 and inclined along the circumference of the piston 320, and the inclination direction of the first guide upper arc plate 3211 is opposite to the inclination direction of the second guide upper arc plate 3221, and a second guide lower arc plate 3222 is provided at one end of the second damping hole 322 located in the second area 332, and the second guide lower arc plate 3222 is inclined to the axis of the piston 320 and inclined along the circumference of the piston 320, and the inclination direction of the first guide lower arc plate 3212 is opposite to the inclination direction of the second guide lower arc plate 3222, and the inclination directions of the second guide lower arc plate 3222 and the second guide upper arc plate 3221 along the circumference of the piston 320 are opposite.

[0065] It is understandable that such a configuration is to enhance the convection effect of the damping fluid in the radial direction of the piston 320 and the circumferential direction of the piston 320. The convection of the damping fluid can also further disperse the heat in the damping fluid and improve the temperature uniformity of the damping fluid.

[0066] In a further embodiment, Figure 4 and Fig.11 As shown, the outside of the damping cylinder 330 is also coaxially fixedly connected with an air-cooling heat dissipation tube 400, both ends of the air-cooling heat dissipation tube 400 are connected, and an air-cooling heat dissipation cavity 410 is formed between the air-cooling heat dissipation tube 400 and the damping cylinder 330, and an exhaust ring 311 is also provided on the outer periphery of the connecting rod 310 and at one end away from the piston 320. The exhaust ring 311 can slide back and forth along the peripheral wall of the air-cooling heat dissipation cavity 410 to accelerate the discharge of hot air in the air-cooling heat dissipation cavity 410.

[0067] When encountering a medium to high magnitude earthquake, the swing amplitude of the steel column 100 increases, thereby increasing the moving distance of the connecting rod 310. At this time, the exhaust ring 311 can move back and forth inside the air-cooled heat dissipation cavity 410, thereby accelerating the discharge of hot air in the air-cooled heat dissipation cavity 410 and improving the heat exchange efficiency, so as to enhance the shock absorption effect of the damping assembly 300.

[0068] In a further embodiment, Figure 4 As shown, a first spring 312 is provided between the exhaust ring 311 and the damping cylinder 330 , and the first spring 312 can be compressed along the axis of the damping cylinder 330 .

[0069] A first spring 312 is provided to reset the reciprocating movement of the exhaust ring 311 and the connecting rod 310 .

[0070] In a further embodiment, a spring assembly 500 is further provided in the air-cooled heat dissipation cavity 410, and the spring assembly 500 includes a first heat-conducting ring 510 and a plurality of second heat-conducting rings 520, the first heat-conducting ring 510 and the plurality of second heat-conducting rings 520 have the same appearance size, the first heat-conducting ring 510 is close to the exhaust ring 311, and the first heat-conducting ring 510 can slide back and forth within a preset distance along the axis of the air-cooled heat dissipation cylinder 400, the plurality of second heat-conducting rings 520 are coaxially connected to the first heat-conducting ring 510, and two adjacent second heat-conducting rings 520 can move synchronously and rotate relatively, and the first heat-conducting ring 510 and the second heat-conducting ring 520 connected thereto can move synchronously and rotate relatively, the plurality of second heat-conducting rings 520 are spirally connected to the outer peripheral wall of the damping cylinder 330, and the spiral angle increases from one end close to the first heat-conducting ring 510 to one end away from the first heat-conducting ring 510. The end gradually decreases, and a plurality of rotating circles 540 are equidistantly arranged on the outer peripheral wall of the air-cooled heat dissipation tube 400. The plurality of rotating circles 540 and the plurality of second heat-conducting rings 520 thereunder are fixedly connected by elastic bars 530. The elastic bars 530 are tilted along the axis of the rotating circle 540. The plurality of elastic bars 530 have a concentrated state and a dispersed state along the axis of the air-cooled heat dissipation tube 400. When in the concentrated state, the plurality of elastic bars 530 are concentratedly distributed along the axis of the air-cooled heat dissipation tube 400. When in the dispersed state, the plurality of elastic bars 530 are dispersedly distributed along the axis of the air-cooled heat dissipation tube 400. A first sliding block 511 is arranged on the outside of the first heat-conducting ring 510, and a first straight slide groove 420 is correspondingly opened on the peripheral wall of the air-cooled heat dissipation tube 400. The first straight slide groove 420 extends along the axis of the air-cooled heat dissipation tube 400, and the first sliding block 511 is slidably connected in the first straight slide groove 420.

[0071] When a low-magnitude earthquake occurs, the exhaust ring 311 moves a small distance, and the exhaust ring 311 cannot exert a force on the first heat-conducting ring 510. At this time, the elastic bars 530 are in a concentrated state, such as Fig.12 As shown, at this time, the elastic bar 530 increases the contact area with the heat dissipation fins to accelerate heat dissipation.

[0072] When encountering a medium to high magnitude earthquake, the movement distance of the exhaust ring 311 increases, and the exhaust ring 311 is pressed down onto the first heat conducting ring 510. The first heat conducting ring 510 approaches the damping cylinder 330 along the direction of its axis. The movement of the first heat conducting ring 510 drives the plurality of second heat conducting rings 520 to rotate around the axis of the damping cylinder 330 and move downward. Since one end of the elastic bar 530 is fixedly connected to the second heat conducting ring 520, the inclination angle of the elastic bar 530 increases. At this time, the elastic bar 530 is in a dispersed state. By reciprocatingly switching between the dispersed state and the concentrated state by the elastic bar 530, it can not only play a role of elastic shock absorption, but also play a role of diversion through the angle change of the elastic bar 530, thereby accelerating the heat in the air-cooled heat dissipation cavity 410 to be discharged outwardly, thereby improving the heat exchange efficiency.

[0073] In a further embodiment, in order to enhance the heat exchange effect and increase the heat exchange time between the air and the damping fluid, the first guide upper arc plate 3211, the first guide lower arc plate 3212, the second guide upper arc plate 3221 and the second guide lower arc plate 3222 are all tilted clockwise, and the elastic bar 530 is tilted counterclockwise, so that the damping fluid flows in a clockwise rotation and the air flows in a counterclockwise rotation, thereby increasing the heat exchange time between the air and the damping fluid.

[0074] In a further embodiment, Figure 5 and Fig.11 As shown, a protrusion 521 is provided on the inner circumferential wall of the second heat conducting ring 520 , a spiral groove 333 is provided on the outer circumferential wall of the damping cylinder 330 , and the protrusion 521 is slidably connected in the spiral groove 333 .

[0075] When the second heat-conducting ring 520 is subjected to force in the axial direction, the second heat-conducting ring 520 rotates along its axis and moves downward under the guidance of the protrusion 521 and the spiral groove 333. At this time, the distance between the second heat-conducting ring 520 and the rotating circle 540 in the axial direction of the second heat-conducting ring 520 increases, so that the inclination angle of the second heat-conducting ring 520 and therefore the elastic bar 530 increases.

[0076] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
