Description

Technical Field

[0001] The invention relates to the technical field of steel structure buildings, in particular to a steel tube concrete frame. Background Art

[0002] Unequal height connection nodes refer to nodes that are connected at different heights or different horizontal planes. This connection method is common in building structures and is mainly used to solve the problem of connecting beams and columns in steel structures. Especially when the columns are of different heights, this connection method can improve the stability and safety of the structure and is suitable for different height connection requirements in various building structures.

[0003] However, the existing unequal height connection nodes between beams and columns are still mostly connected by rigid connection methods such as welding, steel bracket connection, angle steel connection, etc. This rigid connection method makes the building's earthquake resistance poor. Once an earthquake occurs, the structure at the connection node between the beam and the column will become unstable. The structure at the node is difficult to unload the energy generated by the earthquake. The connection between the beam and the column is prone to deformation or collapse, threatening the structural strength of the building. Summary of the invention

[0041] A steel tube concrete frame includes a building beam 100 and a steel tube 200. The building beam 100 is arranged on the steel tube 200. There are at least two building beams 100. At least two building beams 100 can be arranged on the same steel tube 200 in different horizontal planes, and a damping mechanism is arranged between any building beam 100 and the steel tube 200.

[0042] The damping mechanism includes a cylinder 300, a plug disc 400 and a plug rod 500. The cylinder 300 is filled with a damping fluid (not shown in the figure), the plug disc 400 is provided with a damping hole 401, and the plug disc 400 can be slidably arranged in the cylinder 300. The plug rod 500 is fixed to one side of the plug disc 400 and its end away from the plug disc 400 passes through the inner bottom surface of the cylinder 300.

[0043] Specifically, the cross section of the plug disc 400 is circular and matches the cross section of the inner cavity of the cylinder body 300, and the side wall of the plug disc 400 contacts the inner wall of the cylinder body 300. The cylinder body 300 is filled with damping fluid, and the plug rod 500 can push the plug disc 400 to move in the cylinder body 300. During the movement of the plug disc 400, the damping fluid can pass through the damping hole 401 opened on the plug disc 400. When the plug disc 400 moves, the damping fluid can flow through the damping hole 401, and the plug disc 400 will be subject to the resistance of the damping fluid, thereby being able to produce a certain buffering effect on the vibration between the building beam 100 and the steel pipe 200, and making the connection between the building beam 100 and the steel pipe 200 more stable.

[0044] In some embodiments, a buffer mechanism 600 is provided between the cylinder body 300 and the plug disc 400. The buffer mechanism 600 can improve the energy unloading capacity of the damping mechanism in the above embodiments and can make the connection between the building beam 100 and the steel pipe 200 more stable.

[0045] The buffer mechanism 600 includes a movable sleeve 610, a spiral ring piece 620 and a variable pitch thread groove 630. The movable sleeve 610 is connected to one side of the plug disc 400 through a spring 611, a first driving component capable of driving the movable sleeve 610 to rotate is provided between the plug disc 400 and the movable sleeve 610, the variable pitch thread groove 630 is provided on the inner side wall of the cylinder body 300, the spiral ring piece 620 is provided in the variable pitch thread groove 630, a receiving component is provided between the spiral ring piece 620 and the movable sleeve 610, the spiral ring piece 620 rotates synchronously with the movable sleeve 610 through the receiving component, and the spiral ring piece 620 can move along the groove body of the variable pitch thread groove 630 when rotating.

[0046] Specifically, the movable sleeve 610 can be connected to one side of the plug disc 400 through a spring 611, and the movable sleeve 610 can be a metal part. One end of the spring 611 is fixedly connected to one side of the plug disc 400, and the other end is fixedly connected to the movable sleeve 610. The first driving assembly is arranged between the plug disc 400 and the movable sleeve 610, and the movable sleeve 610 can rotate in the cylinder body 300 through the first driving assembly.

[0047] The variable pitch thread groove 630 is provided on the inner side wall of the cylinder body 300, and in the direction parallel to the axial direction of the cylinder body 300, the closer to the end face of the cylinder body 300, the smaller the distance between two adjacent groove bodies in the variable pitch thread groove 630, that is, the smaller the pitch of the variable pitch thread groove 630. The spiral ring piece 620 can be a metal part, and the spiral ring piece 620 is arranged in the variable pitch thread groove 630. A receiving assembly is arranged between the spiral ring piece 620 and the movable sleeve 610, and the spiral ring piece 620 can realize synchronous rotation with the movable sleeve 610 through the receiving assembly. When the spiral ring piece 620 rotates, it can move in the groove body of the variable pitch thread groove 630, which can increase or decrease the pitch of the spiral ring piece 620.

[0048] The spiral ring piece 620 has good thermal conductivity, and the spiral ring piece 620 can be a copper spiral ring. The spiral ring piece 620 is arranged in the variable pitch thread groove 630, which can increase the contact area between the inner wall of the cylinder body 300 and the damping fluid, thereby enhancing the heat dissipation capacity of the cylinder body 300, dissipating the heat in the damping fluid faster, reducing the impact of the damping fluid due to temperature changes, ensuring the normal operation of the damping mechanism, and thus facilitating the stability of the building structure.

[0049] Moreover, when the spiral ring 620 rotates, it can move relative to the groove wall of the variable pitch thread groove 630, thereby generating a certain friction force. This friction force can offset or consume part of the energy generated by the earthquake, which is beneficial to maintaining the connection relationship between the building beam 100 and the steel pipe 200, making the building structure more stable.

[0050] Further, the first driving assembly may include a driving rod 710, a first driving key 720 and a driving groove 730. The driving rod 710 may be fixed to one side of the plug disc 400 and may be inserted into the inner hole of the movable sleeve 610, the spring 611 may be sleeved on the driving rod 710, and the first driving key 720 may be fixed on the side wall of the driving rod 710. The driving groove 730 is provided on the inner hole wall of the movable sleeve 610, the driving groove 730 is a spiral groove, and is adapted to the first driving key 720.

[0051] When the plug disc 400 moves in the cylinder body 300, the drive rod 710 moves synchronously with the first drive key 720 thereon. The first drive key 720 can abut against the groove surface of the spiral groove (drive groove 730) and can apply pressure to the groove surface of the spiral groove, thereby pushing the movable sleeve 610 to rotate.

[0052] The rotation of the movable sleeve 610 can drive the spring 611 to twist, and a reaction force will be generated when the spring 611 twists. The reaction force of the spring 611 can increase the resistance that the plug disc 400 needs to overcome when moving in the cylinder body 300. The movement of the plug disc 400 in the cylinder body 300 depends on the force generated between the steel pipe 200 and the building beam 100 during an earthquake. Therefore, the reaction force of the spring 611 can offset part of the energy generated by the earthquake, which is beneficial to maintaining the structural stability between the steel pipe 200 and the building beam 100.

[0053] In addition, when the first driving key 720 contacts the groove wall of the driving groove 730 and moves relative to the groove wall of the driving groove 730, the friction between the first driving key 720 and the groove wall of the driving groove 730 can also offset or consume part of the energy generated by the earthquake, which is more conducive to maintaining the connection stability between the steel pipe 200 and the building beam 100.

[0054] Furthermore, the receiving assembly may include a rotating ring piece 810, a fixed rod 820 and an auxiliary rod 830. The rotating ring piece 810 is fixed to one end of the spiral ring piece 620. The fixed rod 820 is fixed to the inner hole wall of the rotating ring piece 810, and the length direction of the fixed rod 820 is parallel to the axial direction of the cylinder body 300. One end of the fixed rod 820 can extend to the inside of the spiral ring piece 620.

[0055] The fixed rod 820 is provided with an auxiliary slot 821 parallel to its length direction, the end of the auxiliary slot 821 located inside the spiral ring piece 620 is a closed end, and the end of the auxiliary slot 821 located at the rotating ring piece 810 is an open end. The auxiliary rod 830 is arranged on the outer side wall of the movable sleeve 610 and is parallel to the axial direction of the movable sleeve 610, and the auxiliary rod 830 is adapted to the auxiliary slot 821.

[0056] Specifically, a plurality of fixing rods 820 may be provided, and the plurality of fixing rods 820 are evenly distributed along the inner hole wall of the rotating ring piece 810 , and the auxiliary sliding grooves 821 and the auxiliary rods 830 corresponding to the fixing rods 820 are correspondingly provided.

[0057] When the auxiliary rod 830 is inserted into the corresponding auxiliary sliding groove 821, the movable sleeve 610 rotates, and the auxiliary rod 830 can push the spiral ring piece 620 to rotate, thereby allowing the spiral ring piece 620 to move in the variable pitch thread groove 630. When the spiral ring piece 620 moves in the variable pitch thread groove 630, the friction force generated between the spiral ring piece 620 and the variable pitch thread groove 630 can also offset the energy generated by the earthquake, which is conducive to maintaining the stability of the building.

[0058] When an earthquake occurs, the cylinder body 300 and the plug rod 500 may move away from or towards each other. When the cylinder body 300 and the plug rod 500 move away from each other, the plug rod 500 drives the plug disc 400 to move in the cylinder body 300 in a direction away from the top cover in the cylinder body 300. When the plug disc 400 moves, the drive rod 710 on the plug disc 400 can drive the first drive key 720 to press against the groove wall of the drive groove 730, thereby driving the movable sleeve 610 to rotate. The rotation of the movable sleeve 610 can drive the auxiliary rod 830, the fixed rod 820 and the rotating ring piece 810 to rotate synchronously. The rotating ring piece 810 drives the spiral ring piece 620 to rotate, so that the spiral ring piece 620 can move on the groove surface of the variable pitch thread groove 630.

[0059] When the spiral ring piece 620 moves in the variable pitch thread groove 630, the pitch of the spiral ring piece 620 will increase or decrease. When the pitch of the spiral ring piece 620 increases, the spiral ring piece 620 will be stretched, and the spiral ring piece 620 can contact a larger range of damping fluid. For damping fluid with a higher temperature, the spiral ring piece 620 can transfer heat to the outside of the cylinder body 300 more quickly; when the pitch of the spiral ring piece 620 decreases, the spiral ring piece 620 will be compressed, and the spiral ring piece 620 will be denser. The denser spiral ring piece 620 has better heat dissipation capacity and can transfer the heat near the spiral ring piece 620 to the outside of the cylinder body 300 more quickly.

[0060] When the cylinder body 300 and the plug rod 500 are close to each other, the plug disc 400 will move towards the top cover inside the cylinder body 300. The movement modes of the movable sleeve 610, spiral ring sheet 620 and other components are similar to the movement modes of the corresponding components when the cylinder body 300 and the plug rod 500 are away from each other. The only difference is that the directions are opposite, which will not be repeated here.

[0061] Therefore, no matter whether the cylinder body 300 and the plug rod 500 are close to or far away from each other, the flow of the damping fluid in the damping hole 401, the rotation of the movable sleeve 610, the torsion of the spring 611, and the movement of the spiral ring 620 in the variable pitch thread groove 630 can all consume the vibration energy exerted on the building when an earthquake occurs, and can maintain the stability of the building, that is, the connection stability between the building beam 100 and the steel pipe 200 at structures of unequal heights.

[0062] In addition, the spiral ring sheet 620 can also speed up the heat dissipation of the damping fluid in the cylinder body 300 .

[0063] When the pitch of the spiral ring piece 620 increases, the spiral ring piece 620 can contact the damping liquid in a larger range, and the spiral ring piece 620 can dissipate heat for a larger range of damping liquid; when the pitch of the spiral ring piece 620 decreases, the heat dissipation speed of the dense spiral ring piece 620 is faster than that of the sparse spiral ring piece 620, and the damping liquid in a certain area can be dissipated faster. After that, the damping liquid in this area exchanges heat with the damping liquid in other areas, and the damping liquid as a whole can also be dissipated. The damping liquid with a low temperature can have a better damping effect on the plug disc 400, can better unload the energy generated by the earthquake, and is more conducive to maintaining the stability of the building structure.

[0064] In other embodiments, the buffer mechanism 600, the first drive assembly and the receiving assembly are each provided in two groups, and the two groups of buffer mechanisms 600, the two groups of first drive assemblies and the two groups of receiving assemblies can be symmetrically arranged about the cross-section at the center of the inner cavity of the cylinder body 300, and the cross-section is perpendicular to the axial direction of the cylinder body 300.

[0065] At this time, a buffer mechanism 600, a first driving assembly and a receiving assembly are provided on both sides of the plug disc 400, and the center of the plug disc 400 coincides with the center of the inner cavity of the cylinder body 300, which defines that the plug disc 400 is at an initial position at this time.

[0066] When the plug disc 400 is in the initial state, the spiral ring pieces 620 on both sides of the plug disc 400 are both located at one end of the variable pitch thread groove 630 close to the plug disc 400 and are respectively fixed on the corresponding rotating ring pieces 810 .

[0067] When the plug disc 400 moves toward the inner top cover of the cylinder body 300, the distance between the plug disc 400 and the inner top cover of the cylinder body 300 decreases, and the driving rod 710 on the plug disc 400 drives the first driving key 720 to move. When the plug disc 400 moves, the driving rod 710 located between the plug disc 400 and the inner top cover of the cylinder body 300 drives the first driving key 720 to press against the groove wall of the driving groove 730. The first driving key 720 can push the movable sleeve 610 to rotate, and the movable sleeve 610 drives the spiral ring piece 620 to rotate. When the spiral ring piece 620 rotates, the pitch of the spiral ring piece 620 will gradually decrease due to the limitation of the variable pitch thread groove 630. At this time, the pressure between the plug disc 400 and the inner top cover of the cylinder body 300 will increase, and the temperature will rise. However, the spiral ring piece 620 with a smaller pitch can quickly conduct heat to the damping fluid in this area, dissipate the heat in this area to the outside of the cylinder body 300, and ensure the stability of the damping fluid.

[0068] The spiral ring piece 620 in the area between the plug disc 400 and the inner bottom surface of the cylinder body 300 is located at one end of the variable pitch thread groove 630 close to the plug disc 400, and the spiral ring piece 620 in this area will neither rotate nor move in the axial direction of the cylinder body 300. At this time, the movable sleeve 610 located between the plug disc 400 and the inner bottom surface of the cylinder body 300 will not rotate either. When the plug disc 400 moves toward the direction close to the inner top surface of the cylinder body 300, the plug disc 400 will drive the corresponding movable sleeve 610 to slide along the auxiliary slide groove 821 through the spring 611 and the first drive key 720 located between the plug disc 400 and the inner bottom surface of the cylinder body 300.

[0069] Since the structures on both sides of the plug disc 400 are completely symmetrical, when the plug disc 400 moves toward the inner bottom surface of the cylinder body 300, the actions of the buffer mechanism 600, the first drive assembly and the receiving assembly between the plug disc 400 and the inner bottom surface of the cylinder body 300 are completely consistent with the actions of the corresponding mechanisms or components between the plug disc 400 and the inner top cover of the cylinder body 300, and will not be repeated here.

[0070] In this embodiment, no matter which end of the cylinder body 300 the plug disc 400 moves toward, the spiral ring piece 620 can conduct heat to the damping liquid, accelerate the heat loss in the damping liquid, and help maintain the stability of the damping liquid. Moreover, when the plug disc 400 moves toward the end of the cylinder body 300, the spiral ring piece 620 between the plug disc 400 and the corresponding end of the cylinder body 300 can always move along the corresponding variable pitch thread groove 630. The friction force that the spiral ring piece 620 needs to overcome when moving, the torsional force of the spring 611, the friction between the first drive key 720 and the drive groove 730, etc. can all offset or consume the vibration energy generated when an earthquake occurs, and can maintain the connection stability between the building beam 100 and the steel pipe 200, which is conducive to maintaining the stability of the building.

The thread groove 912 can be provided in two, and the two thread grooves 912 are respectively provided at the two ends of the straight groove 911, and the two thread grooves 912 are symmetrically provided about the straight groove 911, and the straight groove 911 and the thread grooves 912 at both ends thereof are smoothly connected.

[0077] In this embodiment, when the plug disc 400 approaches the inner top cover of the cylinder body 300 , the second driving key 920 disposed on the inner hole wall of the main turntable 411 can move along the power groove on the mounting column 310 .

[0078] When the energy generated by the earthquake is too small and the vibration caused to the building is small, the damping mechanism is stretched or compressed to a small extent. At this time, the second drive key 920 can only move along the straight groove 911 in the power groove, and there is no other adjustment to the size of the damping hole 401.

[0079] When the energy generated by the earthquake is large and the magnitude of the stretching or compression of the damping mechanism is large, the second driving key 920 can slide from the corresponding straight groove 911 into the spiral groove connected thereto, and when sliding into the spiral groove, it can also drive the main rotating disk 411 to rotate in the corresponding main rotating groove 410. The rotation of the main rotating disk 411 can drive the slave rotating disk 421 engaged therewith to rotate, and the rotation of the slave rotating disk 421 can drive the threaded column 4222 on the spoiler 4221 to rotate. When the threaded column 4222 rotates, it can drive the spoiler 4221 to move in the axial direction of the threaded column 4222, thereby making the spoiler 4221 away from the damping hole 401 and expanding the damping hole 401.

[0080] The enlargement of the damping hole 401 can increase the flow rate of the damping fluid in the cylinder 300, thereby enabling the damping fluid with a higher temperature in the cylinder 300 to flow more quickly to the damping fluid with a lower temperature, thereby facilitating heat exchange of the damping fluid and avoiding local overheating that affects the damping capacity of the present invention.
