Description

Technical Field

[0001] The invention relates to the technical field of building structures, in particular to a beam-column structure with earthquake-resistant function. Background Art

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

[0003] For example, Chinese patent CN216195400U discloses a highly seismic-resistant assembled beam-column connection node, which includes a prefabricated beam and a prefabricated column. Both the prefabricated beam and the prefabricated column are square columns. Blocks are provided at the ends of the prefabricated beams, and holes matching the blocks are provided in the prefabricated columns. The prefabricated beams and the prefabricated columns are detachably connected through matching blocks and holes, and a detachable damper is provided between the prefabricated beams and the prefabricated columns. This solution improves the seismic resistance between the prefabricated beams and the prefabricated columns by providing a detachable damper between the prefabricated columns and the prefabricated beams.

[0004] However, in the process of earthquake resistance, the damper between the prefabricated beams and prefabricated columns in the above scheme may not have sufficient internal damping fluid circulation, which may cause the damping fluid to deteriorate in severe cases, thereby reducing the service life of the damper. In addition, when the damper is subjected to high-frequency vibration, the frequent reciprocating motion 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

[0009] Furthermore, the number of through holes on the periphery of the first damping chamber and the number of through holes on the periphery of the second damping chamber are the same and are both even numbers, and one-way valve bodies are disposed in half of the through holes; The through hole with a one-way valve body on the periphery of the first damping chamber of the first damper is communicated with the through hole without a one-way valve body in the first damping chamber of the second damper, and the through hole without a one-way valve body on the periphery of the first damping chamber of the first damper is communicated with the through hole with a one-way valve body in the first damping chamber of the second damper; The through hole with a one-way valve body on the periphery of the second damping chamber of the first damper is connected to the through hole without a one-way valve body on the periphery of the second damping chamber of the second damper; the through hole without a one-way valve body on the periphery of the second damping chamber of the first damper is connected to the through hole with a one-way valve body on the periphery of the second damping chamber of the second damper.

[0010] Furthermore, through holes with one-way valve bodies and through holes without one-way valve bodies are alternately distributed on the outer circumferences of the first damping chamber and the second damping chamber.

[0011] Furthermore, a piston is disposed inside each of the first damper and the second damper, and the piston separates the interior of the first damper and the second damper into a first damping chamber and a second damping chamber. A damping hole is provided on the piston, and the damping hole allows the damping fluid to pass through. An adjusting component is disposed on the piston, and the adjusting component can adjust the degree of difficulty of the damping hole allowing the damping fluid to pass through according to the temperature of the damping fluid, and the degree of difficulty of the damping hole allowing the damping fluid to pass through is positively correlated with the temperature of the damping fluid.

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.

[0023] Refer to the following Figure 1-Figure 7 To describe a beam-column structure with earthquake-resistant function provided by the present invention.

[0024] A beam-column structure with earthquake resistance function is suitable for earthquake resistance of beam-column structures, comprising a longitudinal beam 100 and a transverse beam 110. The longitudinal beam 100 is fixed on the ground or other places, and the transverse beam 110 is fixedly connected to the longitudinal beam 100. A rectangular steel plate 120 is welded to the end of the transverse beam 110. A plurality of threaded holes 130 are opened on the rectangular steel plate 120. The rectangular steel plate 120 is fixedly connected to the longitudinal beam 100 by bolts so as to fix the transverse beam 110 on the longitudinal beam 100. The transverse beam 110 and the longitudinal beam 100 are perpendicular to each other. Figure 1As shown, a first damper 200 and a second damper 210 symmetrical about the cross beam 110 are provided at the connection between the longitudinal beam 100 and the transverse beam 110. Both ends of the first damper 200 and the second damper 210 are hinged on the cross beam 110 and the longitudinal beam 100 respectively. 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 anti-seismic role. The first damper 200 and the second damper 210 can absorb the vibration of the connection position between the cross beam 110 and the longitudinal beam 100 through the damping effect, thereby reducing the amplitude of the cross beam 110 and the longitudinal beam 100 and avoiding fracture at the connection between the cross beam 110 and the longitudinal beam 100.

[0025] When the damper in the prior art is working, the internal damping fluid may not be able to circulate sufficiently, which may cause the damping fluid to deteriorate in severe cases, thereby reducing the service life of the damper and further affecting the seismic resistance of the crossbeam 110 and the longitudinal beam 100. When the damper is subjected to high-frequency vibration, the frequent reciprocating motion of the piston 220 in the damping cylinder 250 will cause the temperature of the damping fluid to rise, resulting in a deterioration in the damping effect.

[0026] Therefore, the present invention adopts the following scheme to overcome the above problems: The first damper 200 and the second damper 210 of the present invention both 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 contain damping fluid. Specifically, the pistons 220 in the first damper 200 and the second damper 210 separate the damping cylinders 250 of the first damper 200 and the second damper 210 into the first damping chamber 260 and the second damping chamber 270, and the first damping chamber 260 and the second damping chamber 270 are both provided with a plurality of through holes 280 on their outer circumferences, such as Figure 7 As shown, each through hole 280 is arranged at an angle, specifically, the axis of each through hole 280 has the same angle with the diameter of the first damping chamber 260 or the second damping chamber 270 and both are obtuse angles, the through holes 280 on the periphery of the first damping chamber 260 of the first damper 200 are connected with the through holes 280 on the periphery of the first damping chamber 260 of the second damper 210, and the through holes 280 on the periphery of the second damping chamber 270 of the first damper 200 are connected with the through holes 280 on the periphery of the second damping chamber 270 of the second damper 210.

[0027] It is understandable that when the ground shakes, Figure 1As shown, assuming that the cross beam 110 deflects downward, the second damper 210 below the cross beam 110 will be shortened, while the first damper 200 above will be extended, and the damping fluid in the second damping chamber 270 of the second damper 210 will enter the first damping chamber 260 through the damping hole 400 on the piston 220 to play a damping role. At the same time, part of the damping fluid 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. The inclined setting causes the damping fluid that enters the second damping chamber 270 of the first damper 200 through the multiple through holes 280 to generate eddy currents; and the damping fluid 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 fluid also generates eddy currents, thereby ensuring that the damping fluid of the first damper 200 and the second damper 210 can fully circulate, thereby avoiding the deterioration of the damping fluid and improving the service life of the first damper 200 and the second damper 210.

[0028] It should be noted that, in order to further improve the anti-seismic capability of the cross beam 110 and the longitudinal beam 100 , there are two first dampers 200 and two second dampers 210 .

[0029] Specifically, in order to facilitate the connection between 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 a plurality of first liquid exchange pipes 300, and both ends of the plurality of first liquid exchange pipes 300 are respectively connected to the through holes 280 on the periphery of the first damping chamber 260 of the first damper 200 and the second damper 210. There are also a plurality of second liquid exchange pipes 310, and both ends of the plurality of second liquid exchange pipes 310 are respectively connected to the first damper 200 and the second damper 2 10, and the through holes 280 on the periphery of the second damping chamber 270, and the multiple first fluid exchange tubes 300 and the multiple second fluid exchange tubes 310 are all exposed to the air. The damping fluid with a higher temperature dissipates heat through the multiple first fluid exchange tubes 300 and the multiple second fluid exchange tubes 310 during the circulation process, and the heat of the damping fluid is transferred to the multiple first fluid exchange tubes 300 and the multiple second fluid exchange tubes 310. The multiple first fluid exchange tubes 300 and the multiple second fluid exchange tubes 310 are in contact with the air to realize heat exchange, thereby being able to play a role in reducing the temperature of the damping fluid.

[0030] In a further embodiment, the number of the first fluid exchange tubes 300 and the second fluid exchange tubes 310 in the present invention are the same and both are an even number, and the directions in which the damping fluid is allowed to flow inside half of the first fluid exchange tubes 300 and the other half of the first fluid exchange tubes 300 are opposite, that is, the even number of first fluid exchange tubes 300 are divided into two groups, and the first group of first fluid exchange tubes 300 is set to allow the damping fluid to flow from the first damping chamber 260 of the first damper 200 into the first damping chamber 260 of the second damper 210, and the second group of first fluid exchange tubes 300 allows the damping fluid to flow from the first damping chamber 260 of the second damper 210 into the first damping chamber 260 of the first damper 200. This structural setting can separate the paths for the damping fluid to enter the first damping chamber 260 of the first damper 200 and the first damping chamber 260 of the second damper 210, so that they are independent of each other and do not affect each other.

[0031] It should be noted that the above-mentioned structure can further enhance the circulation effect and heat dissipation effect of the damping fluid. Specifically, if the paths for the damping fluid to enter the first damping chamber 260 of the first damper 200 and the first damping chamber 260 of the second damper 210 are not separated but all the first fluid exchange tubes 300 are shared, when the vibration amplitude of the cross beam 110 is small, the circulation momentum of the damping fluid will be reduced, so that the damping fluid located in the middle part of the first fluid exchange tube 300 will always be in the first fluid exchange tube 300, resulting in a weakened circulation effect of the damping fluid. For example, when the cross beam 110 vibrates upward with a small amplitude, a small amount of the damping fluid in the first damping chamber 260 of the second damper 210 will enter the first fluid exchange tube 300, and most of the damping fluid in the first fluid exchange tube 300 will enter the first damping chamber 260 of the first damper 200. Due to the small amplitude, Therefore, all the damping fluid in the first fluid exchange tube 300 cannot be squeezed into the first damping chamber 260 of the first damper 200, and a small amount of damping fluid remains in the first fluid exchange tube 300. When the cross beam 110 vibrates downward with a small amplitude, a small amount of the damping fluid in the first damping chamber 260 of the first damper 200 enters the first fluid exchange tube 300. The damping fluid in the first fluid exchange tube 300 flows in the opposite direction. Due to the small amplitude, the damping fluid in the first fluid exchange tube 300 still cannot be completely squeezed into the first damping chamber 260 of the second damper 210, and a part of the damping fluid still remains in the first fluid exchange tube 300. The remaining damping fluid includes the damping fluid remaining in the first fluid exchange tube 300 when the cross beam 110 vibrates upward. These remaining parts of the damping fluid are difficult to circulate when the amplitude of the cross beam 110 is low, which ultimately affects the overall damping fluid circulation efficiency and heat dissipation performance. Through the above-mentioned structural optimization, the retention of damping fluid can be effectively avoided, the heat dissipation and flow performance can be improved, and the damping effect can be enhanced.

[0032] It can be understood that by dividing the multiple first fluid exchange tubes 300 into two groups, and allowing the damping fluid to flow in opposite directions in the two groups of first fluid exchange tubes 300, the circulation flow effect of the damping fluid can be improved when the amplitude of the beam 110 is the same. For example, there are originally six first fluid exchange tubes 300, and the six first fluid exchange tubes 300 have damping fluid passing through them at the same time when the beam 110 vibrates, so that the amount of damping fluid passing through each first fluid exchange tube 300 is small, while in the present invention, only half of the first fluid exchange tubes 300 have damping fluid passing through them, so that the amount of damping fluid passing through each first fluid exchange tube 300 is increased, and liquid retention is reduced, thereby improving the circulation flow effect and further improving the ability of the damping fluid to dissipate heat through the first fluid exchange tubes 300.

[0033] It should be noted that the second fluid exchange tube 310 in the present invention has the same structure as the first fluid exchange tube 300, and the second fluid exchange tube 310 connects the first damper 200 and the second damping chamber 270 of the second damper 210. The specific function is the same as that of the first fluid exchange tube 300, and will not be described in detail here.

[0034] Specifically, in the embodiment of the present invention, a one-way valve body 290 is provided in the through hole 280 to realize the functions of the first liquid exchange pipe 300 and the second liquid exchange pipe 310 .

[0035] The number of through holes 280 on the periphery of the first damping chamber 260 and the second damping chamber 270 of the first damper 200 and the second damper 210 is also an even number, and the number is the same as the number of the first liquid exchange tube 300. Half of the through holes 280 of the even number are provided with a one-way valve body 290, and the function of the one-way valve body 290 is to allow the damping fluid to pass only in one direction, while the other half of the through holes 280 are not provided with a one-way valve body 290. For example, the first damping chamber 260 of the first damper 200 There are six through holes 280 on the periphery, three of the six through holes 280 are provided with a one-way valve body 290, while the other three are not provided with a one-way valve body 290; similarly, the second damping chamber 270 of the first damper 200, the first damping chamber 260 of the second damper 210 and the second damping chamber 270 of the second damper 210 also have six through holes 280 on the periphery, and half of the through holes 280 are provided with a one-way valve body 290, while the other half of the through holes 280 are not provided with a one-way valve body 290.

[0036] It should be noted that, in the present invention, the through hole 280 of the first damping chamber 260 of the first damper 200 having the one-way valve body 290 is connected to the through hole 280 of the first damping chamber 260 of the second damper 210 not having the one-way valve body 290 through a group of first liquid exchange pipes 300, and the through hole 280 of the first damping chamber 260 of the first damper 200 not having the one-way valve body 290 is connected to the through hole 280 of the first damping chamber 260 of the second damper 210 having the one-way valve body 290 through another group of first liquid exchange pipes 300. 00 is connected; similarly, the through hole 280 with a one-way valve body 290 on the periphery of the second damping chamber 270 of the first damper 200 is connected to the through hole 280 without a one-way valve body 290 on the periphery of the second damping chamber 270 of the second damper 210 through a group of second fluid exchange tubes 310, and the through hole 280 without a one-way valve body 290 on the periphery of the second damping chamber 270 of the first damper 200 is connected to the through hole 280 with a one-way valve body 290 on the periphery of the second damping chamber 270 of the second damper 210 through another group of second fluid exchange tubes 310.

[0037] The one-way valve body 290 is provided to realize the function of dividing the damping fluid flow path into two parts by the two groups of first fluid exchange tubes 300 and the two groups of second fluid exchange tubes 310 .

[0038] In a further embodiment, 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 have through holes 280 with one-way valve bodies 290 and through holes 280 without one-way valve bodies 290 are alternately distributed on the periphery, as shown in FIG. Figure 7 As shown, the six through holes 280 with and without one-way valve bodies 290 are alternately distributed, so that the damping fluid can generate vortex when entering the first damping chamber 260 or the second damping chamber 270 of the first damper 200 or the second damper 210, thereby avoiding insufficient circulation of the damping fluid inside the first damper 200 or the second damper 210, and further avoiding deterioration of the damping fluid.

[0039] In a further embodiment, the first damper 200 and the second damper 210 each include a damping cylinder 250 and a connecting rod 230. The connecting rod 230 is arranged on the piston 220 of the first damper 200 and the second damper 210, and the piston 220 is slidingly sealed and arranged in the damping cylinder 250. A damping hole 400 is opened on the piston 220 of the first damper 200 and the second damper 210. The damping hole 400 allows the damping fluid to pass through. The size of the damping hole 400 is small, so that the damping fluid is difficult to pass through and can play a damping role. The connecting rod 230 is one end of the first damper 200 or the second damper 210. 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, such as Figure 3 and Figure 4 As shown, one end of the connecting rod 230 away from the piston 220 is hinged to the longitudinal beam 100. The piston 220 is provided with an adjustment component, which can adjust the difficulty of the damping fluid passing through the damping hole 400. The difficulty of the adjustment component to adjust the damping fluid passing through the damping hole 400 is related to the temperature of the damping fluid.

[0040] 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 hole 400, resulting in a significant decrease in the damping effect. Therefore, the adjustment component of the present invention adjusts the difficulty of the damping hole 400 allowing the damping fluid to pass through according to the temperature of the damping fluid. That is, when the temperature of the damping fluid is higher, the adjustment component increases the difficulty of the damping fluid passing through the damping hole 400, thereby maintaining a good damping effect of the first damper 200 and the second damper 210, and reducing the impact of the increase in the damping fluid temperature on the damping effect.

[0041] Specifically, the adjustment assembly in this embodiment includes an elastic tube 430 and a top pressure block 450. Figure 4 and Figure 5As shown, the upper and lower ends of the damping hole 400 are provided with cover plates 410, and micropores 420 with a diameter smaller than that of the damping hole 400 are provided on the cover plate 410. The two ends of the elastic tube 430 are connected to the upper and lower micropores 420. The damping fluid enters the elastic tube 430 through the micropores 420 and is discharged from the other micropore 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 a top pressure block 450 is sealed and slidably arranged in the cavity 440. The top pressure block 450 can slide radially along the damping hole 400. When the temperature of the damping fluid is high, the gas in the cavity 440 is heated and expanded. The air pressure in the cavity 440 increases, thereby pushing the top pressure block 450 out of the cavity 440. The top pressure block 450 can abut 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 inwardly to reduce the diameter of the elastic tube 430, and the difficulty of the damping fluid passing through the elastic tube 430 increases. If the temperature of the damping fluid is higher, the length of the top pressure block 450 extending out of the cavity 440 is longer, and the degree to which the top pressure block 450 pushes the elastic tube 430 to deform increases, thereby further increasing the difficulty of the damping fluid passing through the elastic tube 430, thereby compensating for the influence of the damping fluid temperature rise on the damping effect.

[0042] It should be noted that when the temperature of the damping fluid decreases, the gas pressure in the cavity 440 on the inner wall of the damping hole 400 on the piston 220 gradually decreases, the force of the top pressure block 450 pushing the elastic tube 430 to deform is reduced, and the elastic tube 430 gradually resets under the action of its own elasticity. The diameter of the elastic tube 430 will gradually reset, thereby being able to adaptively adjust the difficulty of allowing the damping fluid to pass through the elastic tube 430 according to the temperature of the damping fluid.

[0043] In a further embodiment, there are multiple top pressing blocks 450 in this embodiment, such as Figure 4 and Figure 5 As shown, a plurality of pressing blocks 450 are distributed along the axial direction of the damping hole 400 , and the plurality of pressing blocks 450 press the side wall of the elastic tube 430 synchronously.

[0044] Specifically, the elastic tube 430 in the embodiment of the present invention is a bellows.

[0045] 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, and 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 first one-way damping valve 460 and the second one-way damping valve 470 allow the damping fluid to pass through in opposite directions, so that when the piston 220 reciprocates in the first damper 200 or the second damper 210, the damping fluid passes through the micropores 420 on different damping holes 400, that is, the damping holes 400 are divided into two groups. For example, half of the first one-way damping valves 460 can only allow the damping fluid to enter the second damping chamber 270 from the first damping chamber 260, and the other half of the second one-way damping valves 470 can only allow the damping fluid to enter the first damping chamber 260 from the second damping chamber 270.

[0046] The working process of a beam-column structure with earthquake resistance provided by the present invention is described in combination with the above embodiments: Install: A rectangular steel plate 120 is fixedly welded to the end of the crossbeam 110, and 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 crossbeam 110, and multiple first fluid exchange pipes 300 and multiple second fluid exchange pipes 310 are connected to the first damper 200 and the second damper 210.

[0047] Shock-resistant: When the ground vibration causes the longitudinal beam 100 and the cross beam 110 to vibrate, if the cross beam 110 vibrates up and down in the vertical direction, the two first dampers 200 and the two second dampers 210 connected to the cross beam 110 start to work. When the cross beam 110 vibrates upward, the lengths of the two first dampers 200 are shortened, and the lengths of the two second dampers 210 are extended. The pistons 220 of the two first dampers 200 move toward the direction close to the second damping chamber 270. At this time, the pressure in the second damping chamber 270 increases, and part of the damping fluid 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 fluid enters the second damping chamber 270 of the second damper 210 through the second fluid exchange pipe 310. Since the through hole 280 on the outer periphery of the second damping chamber 270 of the second damper 210 is inclined It is arranged obliquely, so when the damping fluid passes through the second fluid exchange pipe 310 and enters the second damping chamber 270 of the second damper 210, eddy currents are generated, thereby allowing the damping fluid to circulate fully; at the same time, the pistons 220 of the two second dampers 210 move toward the first damping chamber 260 so that part of the damping fluid in the first damping chamber 260 enters the second damping chamber 270 from the first one-way damping valve 460 in the damping hole 400 of the piston 220, and part of the damping fluid enters the first damping chamber 260 of the first damper 200 through the first fluid exchange pipe 300. Since the through holes 280 on the periphery of the first damping chamber 260 of the first damper 200 are also arranged obliquely, when the damping fluid passes through the first fluid exchange pipe 300 and enters the first damping chamber 260 of the first damper 200, eddy currents are generated, thereby allowing the damping fluid to circulate fully.

[0048] Similarly, if the cross beam 110 moves downward, the flow direction of the damping fluid is opposite, and the specific process is similar to the above process and will not be described in detail.

[0049] Maintaining damping effect: 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.

[0050] 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.

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.
