Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and particularly to a beam-column structure with seismic resistance function. Background Art

[0002] The beam-column structure is a basic component in building structures and is widely used in various building types, such as residential buildings, office buildings, bridges, industrial factories, etc. The seismic resistance function of the beam-column structure is particularly important. Generally, viscous dampers, buckling-restrained braces, friction dampers, etc. are added to the beam-column structure to enhance the seismic resistance ability of the beam-column and thus reduce the impact of earthquakes.

[0003] For example, Chinese Patent CN216195400U discloses a prefabricated beam-column connection node with high seismic resistance. This solution includes a precast beam and a precast column. Both the precast beam and the precast column are square column bodies. A clamping block is provided at the end of the precast beam, and a hole groove matching the clamping block is provided in the precast column. The precast beam and the precast column are detachably connected through the matching clamping block and hole groove, and a detachable damper is provided between the precast beam and the precast column. This solution improves the seismic resistance between the precast beam and the precast column by providing a detachable damper between the precast column and the precast beam.

[0004] However, in the above solution, the damper between the precast beam and the precast column may have a situation where the internal damping fluid cannot circulate fully during seismic resistance. In severe cases, it may cause the damping fluid to deteriorate, thus reducing the service life of the damper. And when the damper is subjected to high-frequency vibrations, the frequent reciprocating movement of the piston in the damping cylinder causes the temperature of the damping fluid to rise, which will reduce the damping effect. Summary of the Invention

[0005] Based on this, in view of the problem of poor seismic performance of the current beam-column structure, it is necessary to provide a beam-column structure with seismic resistance function.

[0006] The above object is achieved by the following technical solutions:

[0007] A beam-column structure with seismic resistance function includes a longitudinal beam and a cross beam. The end of the cross beam is fixedly connected to the longitudinal beam, and the longitudinal beam and the cross beam are perpendicular to each other. A first damper and a second damper that are symmetrically arranged above and below the cross beam are provided at the connection of the longitudinal beam and the cross beam. The two ends of the first damper and the second damper are respectively hinged to the longitudinal beam and the cross beam;

[0008] Both the first damper and the second damper have a first damping chamber and a second damping chamber. A plurality of through holes are evenly formed on the outer periphery of the first damping chamber and the second damping chamber. The through holes on the first damping chamber of the first damper and the second damper are interconnected, and the through holes on the second damping chamber of the first damper and the second damper are interconnected. When vibrations occur at the connection between the longitudinal beam and the cross beam, the damping fluid in the first damper and the second damper circulates through the plurality of through holes. Each through hole is inclined, and the damping fluid generates eddy currents in the first damper or the second damper.

[0009] Further, a first liquid exchange pipe and a second liquid exchange pipe are arranged between the first damper and the second damper;

[0010] There are a plurality of the first liquid exchange pipes, and both ends of each first liquid exchange pipe are respectively connected to the through holes on the first damping chamber of the first damper and the second damper;

[0011] There are a plurality of the second liquid exchange pipes, and both ends of each second liquid exchange pipe are respectively connected to the through holes on the second damping chamber of the first damper and the second damper.

[0012] Further, the number of the first liquid exchange pipes and the second liquid exchange pipes is the same and is an even number;

[0013] The directions in which the damping fluid is allowed to pass through the interiors of half of the first liquid exchange pipes are opposite to those of the other half of the first liquid exchange pipes;

[0014] The directions in which the damping fluid is allowed to pass through the interiors of half of the second liquid exchange pipes are opposite to those of the other half of the first liquid exchange pipes.

[0015] Further, the number of the through holes on the outer periphery of the first damping chamber and the number of the through holes on the outer periphery of the second damping chamber are the same and are an even number. One-way valve bodies are arranged in half of the through holes;

[0016] The through holes with one-way valve bodies on the outer periphery of the first damping chamber of the first damper are communicated with the through holes without one-way valve bodies on the first damping chamber of the second damper, and the through holes without one-way valve bodies on the outer periphery of the first damping chamber of the first damper are communicated with the through holes with one-way valve bodies on the first damping chamber of the second damper;

[0017] The through holes with one-way valve bodies on the outer periphery of the second damping chamber of the first damper are communicated with the through holes without one-way valve bodies on the outer periphery of the second damping chamber of the second damper, and the through holes without one-way valve bodies on the outer periphery of the second damping chamber of the first damper are communicated with the through holes with one-way valve bodies on the outer periphery of the second damping chamber of the second damper.

[0018] Furthermore, the through-holes with one-way valve bodies and the through-holes without one-way valve bodies are alternately distributed on the outer perimeters of the first damping chamber and the second damping chamber.

[0019] Furthermore, pistons are arranged inside both the first damper and the second damper. The pistons divide the interiors of the first damper and the second damper into a first damping chamber and a second damping chamber. Damping holes are formed in the pistons, allowing damping fluid to pass through. An adjusting assembly is arranged on the pistons. The adjusting assembly can adjust the ease of passage of the damping fluid through the damping holes according to the temperature of the damping fluid. The ease of passage of the damping fluid through the damping holes is positively correlated with the temperature of the damping fluid.

[0020] Furthermore, the adjusting assembly includes an elastic tube and a pressing block. Covers are provided at the upper and lower ends of the damping holes. Micro-holes with diameters smaller than the diameter of the damping holes are formed in the covers. The two ends of the elastic tube communicate with the upper and lower micro-holes. A cavity extending radially along the damping hole is formed in the inner wall of the damping hole. The pressing block is slidably and sealingly arranged in the cavity. When the gas in the cavity expands due to heat, the pressing block is pushed to press the side wall of the elastic tube, and the diameter of the elastic tube decreases.

[0021] Furthermore, there are multiple pressing blocks, and the multiple pressing blocks are distributed along the axial direction of the damping hole.

[0022] Furthermore, there are an even number of damping holes. First one-way damping valves are arranged in the upper micro-holes of half of the damping holes, and second one-way damping valves are arranged in the lower micro-holes of the other half of the damping holes. The directions in which the first one-way damping valves and the second one-way damping valves allow the damping fluid to pass are opposite.

[0023] Furthermore, the elastic tube is a corrugated tube.

[0024] The beneficial effects of the present invention are as follows:

[0025] By connecting the first damping chamber of the first damper and the first damping chamber of the second damper, and the second damping chamber of the first damper and the second damping chamber of the second damper, and the through-holes on the outer perimeters of the first damping chamber and the second damping chamber are all inclined, the damping fluid entering the first damping chamber and the second damping chamber can circulate fully, thereby avoiding the deterioration of the damping fluid and affecting the service life of the first damper and the second damper. At the same time, a plurality of first liquid-changing tubes and second liquid-changing tubes are connected between the through-holes of the first damper and the second damper. The first liquid-changing tubes and the second liquid-changing tubes exposed to the air can also play a role in dissipating heat from the damping fluid.

[0026] The present invention can adaptively adjust the ease of damping fluid passing through the damping holes according to the temperature of the damping fluid by setting an adjusting component, thereby reducing the influence of the increase in the temperature of the damping fluid on the damping effect and maintaining a good damping effect as much as possible.

Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0042] The following refers to Figures 1-7 to describe a beam-column structure with earthquake resistance provided by the present invention.

[0043] A beam-column structure with earthquake resistance, suitable for earthquake resistance of beam-column structures, includes a longitudinal beam 100 and a cross beam 110. The longitudinal beam 100 is fixed on the ground or other places, and the cross beam 110 is fixedly connected to the longitudinal beam 100. A rectangular steel plate 120 is welded to the end of the cross beam 110. A plurality of threaded holes 130 are formed in the rectangular steel plate 120. The rectangular steel plate 120 is fixedly connected to the longitudinal beam 100 through bolts, thereby fixing the cross beam 110 to the longitudinal beam 100, and the cross beam 110 and the longitudinal beam 100 are perpendicular to each other, as Figure 1As shown in the figure, at the connection between the longitudinal beam 100 and the cross beam 110, a first damper 200 and a second damper 210 that are symmetrically arranged above and below the cross beam 110 are provided. The two ends of the first damper 200 and the second damper 210 are respectively hinged to the cross beam 110 and the longitudinal beam 100. When the ground vibrates, the cross beam 110 and the longitudinal beam 100 will also vibrate. Since the cross beam 110 and the longitudinal beam 100 are connected together, the connection position is prone to fracture. Therefore, the first damper 200 and the second damper 210 are provided at the connection position to reduce the vibration at the connection position, thereby playing an earthquake-resistant role. The first damper 200 and the second damper 210 can absorb the vibration at the connection position between the cross beam 110 and the longitudinal beam 100 through the damping effect, thereby weakening the amplitude of the cross beam 110 and the longitudinal beam 100 and avoiding the fracture at the connection between the cross beam 110 and the longitudinal beam 100.

[0044] During the operation of the damper in the prior art, the internal damping fluid may not circulate fully, and in severe cases, the damping fluid may deteriorate, thereby reducing the service life of the damper and further affecting the earthquake-resistant ability of the cross beam 110 and the longitudinal beam 100. Moreover, when the damper is subjected to high-frequency vibration, the frequent reciprocating movement of the piston 220 in the damping cylinder 250 will cause the temperature of the damping fluid to rise, resulting in a poor damping effect.

[0045] Therefore, to overcome the above problems, the present invention adopts the following solutions:

[0046] Both the first damper 200 and the second damper 210 of the present invention have a first damping chamber 260 and a second damping chamber 270, and both the first damping chamber 260 and the second damping chamber 270 are filled with damping fluid. Specifically, the piston 220 in the first damper 200 and the second damper 210 divides the damping cylinder 250 of the first damper 200 and the second damper 210 into a first damping chamber 260 and a second damping chamber 270, and a plurality of through holes 280 are opened on the outer periphery of both the first damping chamber 260 and the second damping chamber 270. As Figure 7 shown, each through hole 280 is inclined, specifically, the axis of each through hole 280 forms the same obtuse angle with the diameter of the first damping chamber 260 or the second damping chamber 270, and the through holes 280 on the outer periphery of the first damping chamber 260 of the first damper 200 are communicated with the through holes 280 on the outer periphery of the first damping chamber 260 of the second damper 210, and the through holes 280 on the outer periphery of the second damping chamber 270 of the first damper 200 are communicated with the through holes 280 on the outer periphery of the second damping chamber 270 of the second damper 210.

[0047] It can be understood that when the ground vibrates, as Figure 1As shown, assuming that the cross beam 110 deflects downward, the second damper 210 below the cross beam 110 will shorten, while the first damper 200 above will elongate. The damping liquid in the second damping chamber 270 of the second damper 210 will enter the first damping chamber 260 through the damping holes 400 on the piston 220 to play a damping role. At the same time, part of the damping liquid in the second damping chamber 270 will enter the second damping chamber 270 of the first damper 200 through the through holes 280 on the outer periphery of the second damping chamber 270. Due to the inclined setting of the multiple through holes 280, the damping liquid entering the second damping chamber 270 of the first damper 200 through the multiple through holes 280 generates eddy currents; while the damping liquid in the first damping chamber 260 of the first damper 200 enters the first damping chamber 260 of the second damper 210 through the through holes 280, and the damping liquid also generates eddy currents, thereby ensuring that the damping liquids of the first damper 200 and the second damper 210 can circulate fully, and further avoiding the deterioration of the damping liquid and improving the service life of the first damper 200 and the second damper 210.

[0048] It should be noted that to further improve the seismic resistance of the cross beam 110 and the longitudinal beam 100, there are two first dampers 200 and two second dampers 210 respectively.

[0049] Specifically, for the convenience of connecting the first damper 200 and the second damper 210, a first liquid exchange pipe 300 and a second liquid exchange pipe 310 are arranged between the first damper 200 and the second damper 210. There are multiple first liquid exchange pipes 300, and both ends of the multiple first liquid exchange pipes 300 are respectively connected to the through holes 280 on the outer periphery of the first damping chambers 260 of the first damper 200 and the second damper 210. There are also multiple second liquid exchange pipes 310, and both ends of the multiple second liquid exchange pipes 310 are respectively connected to the through holes 280 on the outer periphery of the second damping chambers 270 of the first damper 200 and the second damper 210. And the multiple first liquid exchange pipes 300 and the multiple second liquid exchange pipes 310 are all exposed to the air. The damping liquid with a higher temperature dissipates heat through the multiple first liquid exchange pipes 300 and the multiple second liquid exchange pipes 310 during the circulation process. The heat of the damping liquid is transferred to the multiple first liquid exchange pipes 300 and the multiple second liquid exchange pipes 310, and the multiple first liquid exchange pipes 300 and the multiple second liquid exchange pipes 310 contact the air to achieve heat exchange, and thus can play the function of reducing the temperature of the damping liquid.

[0050] In a further embodiment, the number of the first liquid exchange pipes 300 and the second liquid exchange pipes 310 in the present invention is the same and is an even number. The directions of the damping liquid flowing inside half of the first liquid exchange pipes 300 and the other half of the first liquid exchange pipes 300 are opposite. That is to say, the even number of first liquid exchange pipes 300 are divided into two groups. It is set that the first group of first liquid exchange pipes 300 allows the damping liquid to flow from the first damping cavity 260 of the first damper 200 into the first damping cavity 260 of the second damper 210, then the second group of first liquid exchange pipes 300 allows the damping liquid to flow from the first damping cavity 260 of the second damper 210 into the first damping cavity 260 of the first damper 200. This structural setting can separate the paths for the damping liquid to enter the first damping cavity 260 of the first damper 200 and the first damping cavity 260 of the second damper 210, so that they are independent of each other and do not affect each other.

[0051] It should be noted that through the above structural setting, the circulating flow effect and heat dissipation effect of the damping liquid can be further improved. Specifically, as follows, if the paths for the damping liquid to enter the first damping cavity 260 of the first damper 200 and the first damping cavity 260 of the second damper 210 are not separated but all the first liquid exchange pipes 300 are shared, when the vibration amplitude of the cross beam 110 is small, the circulating flow volume of the damping liquid will decrease, resulting in that the damping liquid in the middle part of the first liquid exchange pipes 300 will always be in the first liquid exchange pipes 300, weakening the circulating flow effect of the damping liquid. For example, when the cross beam 110 vibrates slightly upward, a small part of the damping liquid in the first damping cavity 260 of the second damper 210 will enter the first liquid exchange pipes 300, and most of the damping liquid in the first liquid exchange pipes 300 enters the first damping cavity 260 of the first damper 200. Due to the small amplitude, all the damping liquid in the first liquid exchange pipes 300 cannot be squeezed into the first damping cavity 260 of the first damper 200, and there is still a small part of the damping liquid remaining in the first liquid exchange pipes 300. When the cross beam 110 vibrates slightly downward, a small part of the damping liquid in the first damping cavity 260 of the first damper 200 enters the first liquid exchange pipes 300, and the flow direction of the damping liquid in the first liquid exchange pipes 300 is opposite. Due to the small amplitude, the damping liquid in the first liquid exchange pipes 300 still cannot be completely squeezed into the first damping cavity 260 of the second damper 210, and there will still be a part of the damping liquid remaining in the first liquid exchange pipes 300. The remaining part of the damping liquid includes the damping liquid remaining in the first liquid exchange pipes 300 when the cross beam 110 vibrates upward. These remaining parts of the damping liquid are difficult to circulate when the vibration amplitude of the cross beam 110 is low, ultimately affecting the overall damping liquid circulation efficiency and heat dissipation performance. Through the above structural optimization, the retention of the damping liquid can be effectively avoided, the heat dissipation and flow performance can be improved, and thus the damping effect can be enhanced.

[0052] It can be understood that by dividing the multiple first liquid exchange tubes 300 into two groups and allowing the damping liquid to flow in opposite directions in the two groups of first liquid exchange tubes 300, the circulating flow effect of the damping liquid can be improved when the amplitude of the cross beam 110 is the same. For example, there were originally six first liquid exchange tubes 300, and when the cross beam 110 vibrated, the damping liquid passed through all six first liquid exchange tubes 300 simultaneously, resulting in a relatively small amount of damping liquid passing through each first liquid exchange tube 300. In the present invention, only half of the first liquid exchange tubes 300 have damping liquid passing through them, increasing the amount of damping liquid passing through each first liquid exchange tube 300, reducing the liquid retention phenomenon, thereby enhancing the circulating flow effect and further improving the heat dissipation ability of the damping liquid through the first liquid exchange tubes 300.

[0053] It should be noted that the structure of the second liquid exchange tube 310 in the present invention is the same as that of the first liquid exchange tube 300. The second liquid exchange tube 310 connects the second damping cavity 270 of the first damper 200 and the second damper 210. Its specific function is the same as that of the first liquid exchange tube 300 and will not be elaborated here.

[0054] Specifically, in the embodiments of the present invention, a one-way valve body 290 is arranged in the through hole 280 to achieve the functions of the above-mentioned first liquid exchange tube 300 and second liquid exchange tube 310.

[0055] The number of through holes 280 on the outer periphery of the first damping cavity 260 and the second damping cavity 270 of the first damper 200 and the second damper 210 is also an even number, and the number is the same as that of the first liquid exchange tubes 300. In half of the even number of through holes 280, a one-way valve body 290 is arranged. The function of the one-way valve body 290 is to only allow the damping liquid to pass unidirectionally, while in the other half of the through holes 280, no one-way valve body 290 is arranged. For example, there are six through holes 280 on the outer periphery of the first damping cavity 260 of the first damper 200, and three of the six through holes 280 are provided with one-way valve bodies 290, while the other three are not provided with one-way valve bodies 290. Similarly, there are also six through holes 280 on the outer periphery of the second damping cavity 270 of the first damper 200, the first damping cavity 260 of the second damper 210, and the second damping cavity 270 of the second damper 210, and in half of the through holes 280, one-way valve bodies 290 are arranged, while in the other half of the through holes 280, no one-way valve bodies 290 are arranged.

[0056] It should be noted that in the present invention, the through hole 280 with the one-way valve body 290 on the outer periphery of the first damping chamber 260 of the first damper 200 is communicated with the through hole 280 without the one-way valve body 290 on the outer periphery of the first damping chamber 260 of the second damper 210 through a set of first liquid exchange pipes 300, while the through hole 280 without the one-way valve body 290 on the outer periphery of the first damping chamber 260 of the first damper 200 is communicated with the through hole 280 with the one-way valve body 290 on the outer periphery of the first damping chamber 260 of the second damper 210 through another set of first liquid exchange pipes 300; similarly, the through hole 280 with the one-way valve body 290 on the outer periphery of the second damping chamber 270 of the first damper 200 is communicated with the through hole 280 without the one-way valve body 290 on the outer periphery of the second damping chamber 270 of the second damper 210 through a set of second liquid exchange pipes 310, and the through hole 280 without the one-way valve body 290 on the outer periphery of the second damping chamber 270 of the first damper 200 is communicated with the through hole 280 with the one-way valve body 290 on the outer periphery of the second damping chamber 270 of the second damper 210 through another set of second liquid exchange pipes 310.

[0057] Through the above setting of the one-way valve body 290, the function of dividing the flow path of the damping liquid into two parts by the two sets of first liquid exchange pipes 300 and the two sets of second liquid exchange pipes 310 is realized.

[0058] In a further embodiment, the through holes 280 with the one-way valve body 290 and the through holes 280 without the one-way valve body 290 on the outer peripheries of the first damping chamber 260 and the second damping chamber 270 of the first damper 200 and the second damper 210 of the present invention are alternately distributed, specifically as Figure 7 shown, the one-way valve body 290 and the absence of the one-way valve body 290 are alternately distributed among the six through holes 280, so that when the damping liquid enters the first damping chamber 260 or the second damping chamber 270 of the first damper 200 or the second damper 210, eddy currents can be generated, thereby avoiding the insufficient circulation of the damping liquid inside the first damper 200 or the second damper 210, and further avoiding the deterioration of the damping liquid.

[0059] In a further embodiment, both the first damper 200 and the second damper 210 include a damper cylinder 250 and a connecting rod 230. The connecting rod 230 is disposed on the pistons 220 of the first damper 200 and the second damper 210, and the pistons 220 are slidably and sealingly disposed within the damper cylinder 250. Damping holes 400 are formed in the pistons 220 of the first damper 200 and the second damper 210, through which damping fluid passes. The size of the damping holes 400 is small, making it difficult for the damping fluid to pass through, thereby enabling a damping effect. The connecting rod 230 is one end of the first damper 200 or the second damper 210, and a rubber sleeve 240 is sleeved on the connecting rod 230. The rubber sleeve 240 can prevent dust from entering the connection between the connecting rod 230 and the first damper 200 or the second damper 210, as Figure 3 and Figure 4 shown. The end of the connecting rod 230 away from the piston 220 is hinged to the longitudinal beam 100. An adjusting assembly is provided on the piston 220, and the adjusting assembly can adjust the ease of passage of the damping fluid through the damping holes 400. The adjustment of the ease of passage of the damping fluid through the damping holes 400 by the adjusting assembly is related to the temperature of the damping fluid.

[0060] It can be understood that when the temperature of the damping fluid increases, the viscosity of the damping fluid will decrease. At this time, it is easier for the damping fluid to pass through the damping holes 400, resulting in a significant decrease in the damping effect. Therefore, the adjusting assembly of the present invention adjusts the ease of passage of the damping fluid through the damping holes 400 according to the temperature of the damping fluid. That is, when the temperature of the damping fluid is higher, the adjusting assembly increases the difficulty of the damping fluid passing through the damping holes 400, thereby maintaining a good damping effect of the first damper 200 and the second damper 210 and reducing the influence of the increase in the temperature of the damping fluid on the damping effect.

[0061] Specifically, the adjusting assembly in this embodiment includes an elastic tube 430 and a pressing block 450, as Figure 4 and Figure 5As shown, cover plates 410 are provided at the upper and lower ends of the damping hole 400. Micro-holes 420 with diameters smaller than that of the damping hole 400 are provided on the cover plates 410. Both ends of the elastic tube 430 are connected to the upper and lower micro-holes 420. The damping liquid enters the elastic tube 430 through the micro-holes 420 and is discharged from the other micro-hole 420 through the elastic tube 430. A cavity 440 extending radially along the damping hole 400 is provided on the side wall of the damping hole 400, and the pressing block 450 is hermetically and slidably arranged in the cavity 440. The pressing block 450 can slide along the radial direction of the damping hole 400. When the temperature of the damping liquid is relatively high, the gas in the cavity 440 expands due to heat, and the air pressure in the cavity 440 increases, so as to push the pressing block 450 to extend out of the cavity 440. The pressing block 450 can abut against the outer periphery of the elastic tube 430 and can push the elastic tube 430 to deform. Specifically, the side wall of the elastic tube 430 is recessed inward to reduce the diameter of the elastic tube 430, and the difficulty for the damping liquid to pass through the elastic tube 430 increases. The higher the temperature of the damping liquid, the longer the length that the pressing block 450 extends out of the cavity 440, and the greater the degree of deformation of the elastic tube 430 pushed by the pressing block 450, thereby further increasing the difficulty for the damping liquid to pass through the elastic tube 430 and compensating for the influence of the increase in the temperature of the damping liquid on the damping effect.

[0062] It should be noted that when the temperature of the damping liquid decreases, the gas pressure in the cavity 440 on the inner wall of the damping hole 400 of the piston 220 gradually decreases, the force for the pressing block 450 to push the elastic tube 430 to deform decreases, and the elastic tube 430 gradually resets under its own elastic action, and the diameter of the elastic tube 430 will gradually reset, so as to adaptively adjust the difficulty for the damping liquid to pass through the elastic tube 430 according to the temperature of the damping liquid.

[0063] In a further embodiment, there are multiple pressing blocks 450 in this embodiment, such as Figure 4 and Figure 5 As shown, the multiple pressing blocks 450 are distributed along the axial direction of the damping hole 400, and the multiple pressing blocks 450 synchronously press the side wall of the elastic tube 430.

[0064] Specifically, the elastic tube 430 in the embodiment of the present invention is a corrugated tube.

[0065] In a further embodiment, there are multiple damping holes 400 in the present invention, and the number is also an even number. A first one-way damping valve 460 is arranged in the micropores 420 at the upper ends of half of the damping holes 400, while a second one-way damping valve 470 is arranged in the micropores 420 at the lower ends of the other half of the damping holes 400. The directions in which the first one-way damping valve 460 and the second one-way damping valve 470 allow the damping liquid to pass are opposite. When the piston 220 reciprocates in the first damper 200 or the second damper 210, the damping liquid passes through the micropores 420 on different damping holes 400, that is, the damping holes 400 are divided into two groups. For example, only half of the first one-way damping valves 460 allow the damping liquid to enter the second damping chamber 270 from the first damping chamber 260, while the other half of the second one-way damping valves 470 only allow the damping liquid to enter the first damping chamber 260 from the second damping chamber 270.

[0066] The working process of a beam-column structure with earthquake resistance provided by the present invention will be described in combination with the above embodiments:

[0067] Installation:

[0068] A rectangular steel plate 120 is fixedly welded to the end of the cross beam 110. The rectangular steel plate 120 is fixedly connected to the longitudinal beam 100 by bolts. Two first dampers 200 and two second dampers 210 are hinged to the longitudinal beam 100 and the cross beam 110, and a plurality of first liquid exchange pipes 300 and a plurality of second liquid exchange pipes 310 are connected to the first dampers 200 and the second dampers 210.

[0069] Earthquake resistance:

[0070] When the ground vibration causes the longitudinal beam 100 and the cross beam 110 to vibrate, if the cross beam 110 vibrates vertically up and down, the two first dampers 200 and the two second dampers 210 connected to the cross beam 110 will start to work. When the cross beam 110 vibrates upward, the lengths of the two first dampers 200 shorten, and the lengths of the two second dampers 210 elongate. The pistons 220 of the two first dampers 200 move towards the direction close to the second damping chamber 270. At this time, the pressure in the second damping chamber 270 increases. Part of the damping liquid in the second damping chamber 270 enters the first damping chamber 260 through the second one-way damping valve 470 in the damping hole 400 on the piston 220, and part of the damping liquid enters the second damping chamber 270 of the second damper 210 through the second liquid exchange pipe 310. Since the through holes 280 on the outer periphery of the second damping chamber 270 of the second damper 210 are inclined, when the damping liquid enters the second damping chamber 270 of the second damper 210 through the second liquid exchange pipe 310, eddy currents will be generated, so that the damping liquid can circulate fully; at the same time, the pistons 220 of the two second dampers 210 move towards the direction close to the first damping chamber 260, so that part of the damping liquid in the first damping chamber 260 enters the second damping chamber 270 through the first one-way damping valve 460 in the damping hole 400 of the piston 220, and part of the damping liquid enters the first damping chamber 260 of the first damper 200 through the first liquid exchange pipe 300. Since the through holes 280 on the outer periphery of the first damping chamber 260 of the first damper 200 are also inclined, when the damping liquid enters the first damping chamber 260 of the first damper 200 through the first liquid exchange pipe 300, eddy currents will be generated, so that the damping liquid can circulate fully.

[0071] Similarly, if the cross beam 110 moves downward, the flow direction of the damping liquid is opposite, and the specific process is similar to the above process and will not be described in detail here.

[0072] Maintain damping effect:

[0073] As the vibration frequency increases, the temperature of the damping fluid increases with the increase of working time. The damping fluid can dissipate some heat when passing through the multiple first fluid exchange tubes 300 and the multiple second fluid exchange tubes 310. Since the multiple first fluid exchange tubes 300 and the multiple second fluid exchange tubes 310 are all exposed to the air, they have a certain heat exchange capacity, thereby being able to dissipate heat for the damping fluid. If the temperature of the damping fluid is still high, the temperature in the cavity 440 of the inner wall of the damping hole 400 on the piston 220 of the first damper 200 and the second damper 210 will increase, the gas in the cavity 440 will expand due to the heat, and the air pressure in the cavity 440 will increase, so that the top pressure block 450 inside the cavity 440 can be pushed out of the cavity 440, the top pressure block 450 pushes the elastic tube 430, the side wall of the elastic tube 430 is concave inward, and multiple top pressure blocks 450 push the elastic tube 430 at the same time, so that the elastic tube 430 is bent, thereby increasing the difficulty of the damping fluid passing through the elastic tube 430; if the temperature of the damping fluid decreases, the air pressure in the cavity 440 will gradually decrease, the elastic tube 430 will gradually return to its original position, and the difficulty of the damping fluid passing through the elastic tube 430 will gradually decrease, so that the difficulty of the damping fluid passing through the elastic tube 430 can be adjusted according to the temperature of the damping fluid, and the damping effect can be maintained as little as possible without a significant change.

[0074] 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.

[0075] 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.
