Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and particularly relates to the beam-column connection structure of buildings. Background Technology

[0002] Building support beams and columns are generally connected by welding or assembly. Both of these connection methods are fixed connections. Although they can ensure a stable connection between the support beam and the support column, under certain vibrations, such as vibrations from vehicles driving on the road or vibrations caused by the use of equipment in a factory, the vibrations will be transmitted from the ground and the support column to the connection node and the support beam in sequence. Over time, this will cause the connection node between the support column and the support beam to loosen, affecting the stability of the support beam. Summary of the Invention

[0003] In view of this, the present invention provides a building beam-column connection structure that can absorb vertical and horizontal vibrations of the supporting beam to ensure the stability of the supporting beam.

[0004] To achieve the above objectives, the present invention provides the following technical solutions.

[0005] 1. A building beam-column connection structure, including a supporting beam and a supporting column. A beam support platform is provided on one side of the supporting column. The supporting beam is horizontally installed on the beam support platform of two adjacent supporting columns. It also includes a vibration absorption mechanism, which is set between the beam end of the supporting beam and the beam support platform to absorb horizontal and vertical vibrations when the ground vibrates. The vibration absorption mechanism includes a friction pendulum and an elastic vibration absorption block. The elastic vibration absorption block is installed on the beam support platform and is used to absorb vertical vibrations. The friction pendulum is installed between the beam end of the supporting beam and the elastic vibration absorption block and is used to absorb horizontal vibrations.

[0006] The vibration absorption mechanism uses elastic vibration absorption blocks and friction pendulums to absorb vibrations in the vertical and horizontal directions, respectively. The elastic vibration absorption blocks can be thick rubber supports. When the vibrations transmitted from the ground and the support column are in the vertical direction, the elastic vibration absorption blocks use their own elasticity to consume the vibrations in that direction, thereby playing a vibration isolation role and reducing the vertical vibration energy transmitted to the support beam. The friction pendulum consists of an upper plate, a lower plate, and a slider positioned between the upper and lower plates. When the vibration transmitted from the ground and the support column is horizontal, the support column will sway horizontally, and the lower plate of the friction pendulum will swing left and right along with the beam support platform on the support column. The slider will also slide back and forth like a pendulum under the friction force of the lower plate. That is to say, relative sliding will occur between the lower plate and the slider, and relative sliding will also occur between the upper plate and the slider. The friction force generated during this sliding process will consume vibration energy to continuously reduce the horizontal vibration energy received by the support beam. Therefore, the elastic vibration absorber and the friction pendulum can reduce the vibration fatigue of the support beam and ensure the service life of the support beam and the stability of the support.

[0007] 2. Based on technical solution 1, it also includes a sliding rotation mechanism. The sliding rotation mechanism is installed between the friction pendulum and the beam end of the support beam. When the support beam is subjected to a vertical load, the beam end of the support beam flips upward and moves along the length of the support beam through the sliding rotation mechanism to avoid uneven force on the friction pendulum.

[0008] 3. Based on technical solution 2, the sliding rotation mechanism includes a rotating support for the rotation of the support beam and a sliding support for the movement of the support beam. The rotating support includes a rotating shaft support, a rotating sleeve, and a rotating shaft. The rotating shaft support is installed on the upper side of the friction pendulum, the rotating shaft is installed on the rotating shaft support, and the rotating sleeve is fitted onto the rotating shaft and can rotate around the rotating shaft. The sliding support includes a sliding sleeve and a transverse sliding block. The sliding sleeve is connected to the beam end of the support beam. The sliding sleeve is provided with a sliding groove. One end of the transverse sliding block is inserted into the sliding groove of the sliding sleeve and can move along the axis of the sliding groove. The other end of the transverse sliding block is connected to the rotating sleeve.

[0009] 4. Based on technical solution 3, the sliding groove of the sliding sleeve is a cavity structure with sealed ends, and the transverse slider is a piston-type block structure. The slider and the two ends of the sliding groove respectively form a sealed cavity. Each sealed cavity is filled with damping oil. A small hole is opened on the transverse slider to connect the two sealed cavities. When the transverse slider squeezes the damping oil in one of the sealed cavities, the small hole on the transverse slider can slow down the speed at which the damping oil on that side flows to the other sealed cavity, so as to reduce the relative movement speed between the transverse slider and the sliding sleeve.

[0010] 5. Based on technical solution 3, a hinge locking mechanism is also included. The hinge locking mechanism is installed in the rotating support and the sliding support to lock the rotating support and the sliding support in place when the support beam is assembled with the sliding support.

[0011] 6. Based on technical solution 5, the hinge locking mechanism includes a locking block, a return spring, a longitudinal rod, and a transverse rod. A mounting groove is provided on the rotating shaft, and a limiting groove is provided on the rotating sleeve. The limiting groove is opposite to the mounting groove. The return spring is installed in the mounting groove. One end of the locking block is connected to the return spring, and the other end extends out of the mounting groove and is inserted into the limiting groove to lock the rotating sleeve in place. A "T"-shaped insertion hole is provided on the transverse sliding block, with the bottom end of the "T"-shaped insertion hole extending towards the rotating sleeve and communicating with the limiting groove on the rotating sleeve. A limiting hole is provided on the sliding sleeve. The limiting hole is opposite to the "T" shaped insertion hole. The longitudinal rod and the transverse rod are cross-shaped and fixedly connected. The longitudinal rod passes through the limiting hole and is inserted into the "T" shaped insertion hole. The bottom end of the longitudinal rod is aligned with the locking block, and the top end extends out of the sliding sleeve. The transverse rod is in the limiting hole and locks the sliding sleeve in place. When the beam end of the support beam moves down and aligns with the sliding sleeve, the beam end of the support beam contacts and presses the longitudinal rod to move down. The transverse rod moves down with the longitudinal rod and gradually moves out of the limiting hole to unlock the sliding support. The longitudinal rod contacts and presses the locking block to move out of the limiting groove to unlock the rotating support.

[0012] 7. Based on technical solution 6, the hinge locking mechanism also includes an unlocking link. The unlocking link is installed at the top of the longitudinal rod and can rotate. When the support beam presses down on both ends of the unlocking link at the same time, the longitudinal rod can be squeezed to move downward. Attached Figure Description

[0023] The invention will be described in detail below with reference to specific embodiments.

[0024] Figure 1 A schematic diagram of the overall structure of the beam-column connection structure in this embodiment is shown, as follows: Figure 1 As shown, the building beam-column connection structure of this embodiment includes a supporting beam 1, a supporting column 2, and a vibration-absorbing mechanism 3. A beam support platform 21 is provided on one side of the supporting column 2. The supporting beam 1 is horizontally installed on the beam support platforms 21 of two adjacent supporting columns 2. The vibration-absorbing mechanism 3 is disposed between the beam end of the supporting beam 1 and the beam support platform 21 to absorb horizontal and vertical vibrations during ground vibrations. Figure 2 As shown, the vibration absorption mechanism 3 includes a friction pendulum 31 and an elastic vibration absorption block 32. The elastic vibration absorption block 32 is installed on the beam support platform 21 and is used to absorb vertical vibrations. The friction pendulum 31 is installed between the beam end of the support beam 1 and the elastic vibration absorption block 32 and is used to absorb horizontal vibrations.

[0025] A vibration absorption mechanism 3 is installed between the support column 2 and the support beam 1 to reduce the vibration energy received by the support beam 1 and ensure the stability of the support beam 1. Specifically, the vibration absorption mechanism 3 uses an elastic vibration absorption block 32 and a friction pendulum 31 to absorb vibrations in the vertical direction and the horizontal direction, respectively. The elastic vibration absorption block 32 can be a thick rubber support. When the vibration transmitted from the ground and the support column 2 is in the vertical direction, the elastic vibration absorption block 32 uses its own elasticity to consume the vibration in that direction, thereby playing a vibration isolation role and reducing the vertical vibration energy transmitted to the support beam 1. Figure 3 A schematic diagram of the specific structure of the friction pendulum 31 in this embodiment is shown, as follows: Figure 3As shown, the friction pendulum 31 includes an upper seat plate 311, a lower seat plate 312, and a friction slider 313 disposed between the upper seat plate 311 and the lower seat plate 312. When the vibration transmitted from the ground and the support column 2 is horizontal, the support column 2 will sway horizontally. The lower seat plate 312 of the friction pendulum 31 will swing left and right together with the beam support platform 21 on the support column 2 via the elastic vibration damping block 32. The friction slider 313 will slide back and forth like a pendulum under the friction force of the lower seat plate 312. That is to say, there will be relative sliding between the lower seat plate 312 and the friction slider 313, and there will also be relative sliding between the upper seat plate 311 and the friction slider 313. The friction force generated during this sliding process will consume vibration energy to continuously reduce the horizontal vibration energy received by the support beam 1. Therefore, the elastic vibration damping block 32 and the friction pendulum 31 can reduce the vibration fatigue of the support beam 1 and ensure the service life and support stability of the support beam 1.

[0026] After the support beam 1 is erected, it generally needs to support other building structures, so it will bend downwards in the vertical direction. This causes the beam end of the support beam 1 to tilt upwards. Since the beam end of the support beam 1 is pressed on the friction pendulum 31, the force on the side of the friction pendulum 31 closer to the beam end of the support beam 1 is smaller, and the force on the side of the beam end farther away from the support beam 1 is larger. In other words, the left and right sides of the friction pendulum 31 will be unevenly stressed, which may lead to unexpected deformation or tilting of the friction pendulum 31. The friction slider 313 in the friction pendulum 31 will experience reduced sliding displacement and reduced sliding efficiency due to the uneven force on the left and right sides, affecting the friction energy dissipation effect.

[0027] This embodiment uses a sliding rotation mechanism 4 with two degrees of freedom to solve the problem, such as... Figure 1 , Figure 2 and Figure 3As shown, the sliding rotation mechanism 4 is installed between the friction pendulum 31 and the beam end of the support beam 1. When the support beam 1 is subjected to a vertical load, the beam end of the support beam 1 is flipped upward and moved along the length of the support beam 1 via the sliding rotation mechanism 4 to avoid uneven force on the friction pendulum 31. Specifically, the sliding rotation mechanism 4 includes a rotating support 41 for flipping the support beam 1. The rotating support 41 includes a pivot support 411, a rotating sleeve 412, and a pivot 413. The pivot support 411 is installed on the upper side of the friction pendulum 31, the pivot 413 is installed on the pivot support 411, and the rotating sleeve 412 is fitted around the pivot 413 and can rotate around the pivot 413. When the support beam 1 is bent vertically downward, the beam end of the support beam 1 will flip along with the rotating sleeve 412 via the sliding support 42 while tilting upward. At this time, the pivot support 411 remains horizontal and stationary, and the friction pendulum 31 is subjected to relatively uniform force. Therefore, with the rotating support 41 providing the beam end of the support beam 1 with the freedom to tilt upward, even if the beam end of the support beam tilts upward due to the vertical load on the support beam 1, the pressure on the friction pendulum 31 is uniform, ensuring the friction energy dissipation effect of the friction pendulum 31. When the end of the supporting beam tilts up, the supporting beam 1, due to its own weight and the load it bears, will exert a tensile force along the length of the supporting beam 1 on the rotating support 41, that is, a downward tensile force. This tensile force will be transmitted to the friction pendulum 31 through the rotating support 41, and will also cause uneven force on the friction pendulum 31. Therefore, the sliding rotation mechanism 4 also includes a sliding support 42 for moving the supporting beam 1, such as... Figure 3 and Figure 4 As shown, the sliding support 42 includes a sliding sleeve 421 and a transverse sliding block 422. The sliding sleeve 421 is connected to the beam end of the support beam 1. The sliding sleeve 421 has a groove 4211 inside and a slide rail 4212 on its side wall. One end of the transverse sliding block 422 passes through the slide rail 4212 on the sliding sleeve 421 and is inserted into the groove 4211 of the sliding sleeve 421. The transverse sliding block 422 can move along the axis of the groove 4211. The other end of the transverse sliding block 422 is connected to a rotating sleeve. 412 and become one unit. The sliding support 42 provides the beam end of the support beam 1 with the freedom to move along the length direction of the support beam 1. In this way, while the beam end of the support beam 1 is tilted upward, it will also move a small distance along the length direction of the support beam 1 until the support beam 1 no longer bends downward. At this time, the force exerted by the beam end of the support beam 1 on the rotating support 41 is only the pressure perpendicular to the support surface of the rotating support 41. The friction pendulum 31 is still subjected to uniform force, which ensures the friction energy dissipation effect of the friction pendulum 31.

[0028] Because a friction pendulum 31 and a sliding support 42 are provided between the support beam 1 and the support column 2, and both the friction pendulum 31 and the sliding support 42 have a degree of freedom to move left and right in the horizontal direction, when the support column 2 is subjected to horizontal vibration, the upper seat plate 311 of the friction pendulum 31 slides laterally back and forth, and at the same time, it also drives the transverse sliding block 422 in the sliding support 42 to slide laterally back and forth in the sliding groove 4211 of the sliding sleeve 421 through the rotating support 41. The superposition of these two transverse back and forth sliding makes the vibration of the support beam 1 very complicated, and may even cause the friction pendulum 31 and the sliding support 42 to resonate, resulting in an increase in the horizontal vibration amplitude of the support beam 1. It is like placing two superimposed blocks on the palm of your hand. When the palm moves back and forth quickly, when the uppermost block resonates with the palm, its transverse displacement is large, which means that its horizontal amplitude is increased.

[0029] In this embodiment, the sliding support 42 is designed as a hydraulic cylinder to solve the problem. Figure 3 and Figure 4 A schematic diagram of the specific structure of the sliding support 42 is shown, as follows: Figure 3 and Figure 4As shown, in this embodiment, the sliding groove 4211 of the sliding sleeve 421 is a cavity structure sealed at both ends, and the transverse slider 422 is a piston-type block structure. The transverse slider 422 and the two ends of the sliding groove 4211 respectively form a sealed cavity. Each sealed cavity is filled with damping oil. A small hole 4221 is opened on the transverse slider 422 to connect the two sealed cavities. When the transverse slider 422 squeezes the damping oil in one of the sealed cavities, the small hole 4221 on the transverse slider 422 can slow down the speed at which the damping oil on that side flows to the other sealed cavity, so as to reduce the relative movement speed between the transverse slider 422 and the sliding sleeve 421. When the sliding support 42 vibrates at a relatively high frequency, the damping oil at both ends of the transverse slider 422 can, to a certain extent, eliminate the horizontal degree of freedom of the sliding support 42. Specifically, since the transverse slider 422 is connected to the friction pendulum 31 via the rotating support 41, when the friction pendulum 31 reciprocates laterally due to horizontal vibration, the transverse slider 422 will reciprocate along with the friction pendulum 31. When the transverse slider 422 moves to the left with the friction pendulum 31, it will squeeze the damping oil in the left sealing cavity. The damping oil flows to the right sealing cavity through the small hole 4221 on the transverse slider 422. Because the diameter of the small hole 4221 is small, the flow speed of the damping oil can be reduced, thus reducing the distance between the transverse slider 422 and the sliding sleeve 4. The relative movement speed between 21, and when the vibration frequency is high, the damping oil on the left may not have time to flow to the right before the transverse slider 422 changes the direction of compression, causing the damping oil on the right to start flowing to the left. This cycle repeats, and the position of the transverse slider 422 relative to the sliding sleeve 421 remains basically unchanged. At this time, the transverse slider 422 and the sliding sleeve 421 can be regarded as a whole, and the degree of freedom of lateral sliding between the two can be ignored. In other words, the design of the damping oil makes the degree of freedom of horizontal movement between the support beam 1 and the support column 2 regarded as only one. This avoids the consequences of the superposition of two transverse reciprocating sliding, and also avoids the problem of increased amplitude of the support beam 1 due to resonance. Although the design of the small hole 4221 on the transverse slider 422 slows down the flow of damping oil, when the end of the support beam 1 needs to move along its length, the tension of the support beam 1 on the sliding sleeve 421 is continuous, and the extrusion pressure of the sliding sleeve 421 on the damping oil on one side is also continuous. The damping oil on that side can flow to the other side through the small hole 4221 to realize the movement of the sliding sleeve 421. In other words, the design of the damping oil between the sliding sleeve 421 and the transverse slider 422, as well as the design of the small hole 4221 on the transverse slider 422, can only realize the relative sliding between the sliding sleeve 421 and the transverse slider 422 when the extrusion pressure is a continuous force. When the extrusion pressure is an instantaneous force or the duration is short, the relative displacement between the sliding sleeve 421 and the transverse slider 422 can be ignored.It should be noted that since the transverse slider 422 is inserted into the slide groove 4211 from the slide rail 4212 on the side wall of the slide sleeve 421, and the slide sleeve 421 also needs to move along the axis of the transverse slider 422, and damping oil is filled between the slide sleeve 421 and the transverse slider 422, in order to avoid leakage of damping oil, the structure between the transverse slider 422 and the slide groove 4211 is similar to that of a hydraulic cylinder. The damping oil on both sides can only flow through the small hole 4221 on the transverse slider 422. At the same time, the length of the transverse slider 422 must be longer than the length of the slide rail 4212 to avoid leakage of damping oil on both sides during the relative sliding process of the transverse slider 422 and the slide sleeve 421.

[0030] Because the sliding rotation mechanism 4 has two degrees of freedom, it is easy for the sliding rotation mechanism 4 to rotate and move horizontally during assembly of the support beam 1 and the sliding rotation mechanism 4. This makes it difficult to align the mounting screw holes on the support beam 1 and the sliding rotation mechanism 4. Therefore, during assembly of the support beam 1 and the sliding rotation mechanism 4, a hinge locking mechanism 5 is used to lock the position of the sliding rotation mechanism 4 until the mounting screw holes on the support beam 1 and the sliding rotation mechanism 4 are aligned, at which point the sliding rotation mechanism 4 is unlocked. Specifically, Figure 3 and Figure 4 The diagram shows the states of the hinge locking mechanism 5 before and after unlocking the rotating support 41 and the sliding support 42, as shown below. Figure 3 and Figure 4 As shown, in this embodiment, the hinge locking mechanism 5 is installed in the rotating support 41 and the sliding support 42. The hinge locking mechanism 5 includes a locking block 51, a return spring 52, a longitudinal rod 53, and a transverse rod 54. A mounting groove 4131 is provided on the rotating shaft 413, and a limiting groove 4121 is provided on the rotating sleeve 412. Before the rotating sleeve 412 rotates, the limiting groove 4121 is opposite to the mounting groove 4131. The return spring 52 is installed in the mounting groove 4131. One end of the locking block 51 is connected to the return spring 52, and the other end extends out of the mounting groove 4131 and is inserted into the limiting groove 4121. Figure 3As can be seen, the rotating shaft 413 is fixed, so when the locking block 51 is simultaneously in the mounting groove 4131 of the rotating shaft 413 and the limiting groove 4121 of the rotating sleeve 412, the rotating sleeve 412 can be locked in place. The transverse slider 422 has a "T"-shaped insertion hole 4222. Since the transverse slider 422 is integrally connected to the rotating sleeve 412, the bottom end of the "T"-shaped insertion hole 4222 can extend towards the rotating sleeve 412 and communicate with the limiting groove 4121 on the rotating sleeve 412. The sliding sleeve 421 has a limiting hole 4213. When the transverse slider 422 and the sliding sleeve 421 are opposite... Before sliding, the limiting hole 4213 is opposite to the "T"-shaped insertion hole 4222. The longitudinal rod 53 and the transverse rod 54 are cross-shaped and fixedly connected as one piece. The transverse rod 54 is located near the top of the longitudinal rod 53. The longitudinal rod 53 passes through the limiting hole 4213 and is inserted into the "T"-shaped insertion hole 4222. The bottom end of the longitudinal rod 53 is aligned with the locking block 51, and the top end extends out of the sliding sleeve 421. The transverse rod 54 is in the limiting hole 4213. When the transverse sliding block 422 remains stationary, the transverse rod 54 also remains stationary. Therefore, the transverse rod 54 can lock the sliding sleeve 421 in place. Figure 4 As can be seen, when the beam end of the support beam 1 moves down and aligns with the sliding sleeve 421, the beam end of the support beam 1 contacts and presses the longitudinal rod 53 to move down. The transverse rod 54 moves down with the longitudinal rod 53 and gradually moves out of the limiting hole 4213. At this time, the sliding sleeve 421 is no longer limited by the transverse rod 54 and can move relative to the transverse slider 422 to unlock the sliding support 42. During the downward movement, the longitudinal rod 53 contacts and presses the locking block 51 to move out of the limiting groove 4121. At this time, the rotating sleeve 412 is no longer limited by the locking block 51 and can rotate around the rotating shaft 413 to unlock the rotating support 41. It should also be noted that if the longitudinal rod 53 is squeezed down too far, it may extend into the mounting groove 4131 of the rotating shaft 413, which will limit the rotation angle of the rotating sleeve 412 to a certain extent. Therefore, the insertion hole on the transverse slider 422 adopts a "T" shaped insertion hole 4222. Since the transverse slider 422 remains stationary under the limit of the rotating sleeve 412, the transverse rod 54 gradually inserts into the "T" shaped insertion hole 4222 of the transverse slider 422 during the downward movement until the transverse rod 54 abuts against the upper step surface of the "T" shaped insertion hole 4222 and stops moving down. This also limits the downward movement of the longitudinal rod 53. At this time, the bottom end of the longitudinal rod 53 is at the contact surface between the rotating shaft 413 and the rotating sleeve 412, which realizes the unlocking of the rotating sleeve 412 without limiting the rotation angle of the rotating sleeve 412.

[0031] Because the hinge locking mechanism 5 is only triggered at the middle of the top of the longitudinal rod 53, if the support beam 1 tilts when it is lowered during hoisting, its end can easily trigger the unlocking hinge locking mechanism 5. This requires the sliding rotation mechanism 4 to reset before the assembly of the support beam 1 can continue, affecting the construction progress. Figure 3 and Figure 4 As shown, in this embodiment, an unlocking link 55 is installed at the top of the longitudinal rod 53. Each end of the unlocking link 55 has a contact 551 that extends upward. The middle position of the unlocking link 55 is movably connected to the longitudinal rod 53, forming a lever at the connection point with the longitudinal rod 53. At the same time, a link placement groove 4214 is opened on the upper surface of the sliding sleeve 421. The unlocking link 55 is located in the link placement groove 4214 and can swing up and down. When one end contact 551 of the unlocking link 55 is subjected to force, that end will flip downward without causing the longitudinal rod 53 to move downward as a whole. Only when both ends contact 551 of the unlocking link 55 are subjected to force simultaneously will the longitudinal rod 53 move downward. This design can prevent the lifting support beam 1 from triggering the hinge locking mechanism 5 to unlock prematurely due to tilting. Only when the entire beam end of the support beam 1 is close to the sliding support 42 and nearly horizontal can the two ends contact 551 of the unlocking link 55 be pressed down simultaneously to trigger unlocking, reducing the risk of false locking. At the same time, it can also ensure that the mounting screw holes of the support beam 1 and the mounting screw holes of the sliding support 42 are aligned when the unlocking link 55 is pressed down, which facilitates subsequent installation.

One end of the locking block is connected with the return spring. The other end of the locking block extends out of the installation groove and is inserted into the limiting groove to lock the rotating sleeve. A "T"-shaped insertion hole is opened on the horizontal sliding block. The bottom end of the "T"-shaped insertion hole extends to the side of the rotating sleeve and communicates with the limiting groove on the rotating sleeve. A limiting hole is opened on the sliding sleeve and opposite to the "T"-shaped insertion hole. The longitudinal rod and the transverse rod are cross-connected and fixedly connected. The longitudinal rod penetrates through the limiting hole and is inserted into the "T"-shaped insertion hole. The bottom end of the longitudinal rod is aligned with the locking block. The top end of the longitudinal rod extends out of the sliding sleeve. The transverse rod is in the limiting hole and locks the sliding sleeve. When the beam end of the support beam moves downward and is aligned with the sliding sleeve, the beam end of the support beam contacts and extrudes the longitudinal rod to move downward. The transverse rod moves downward with the longitudinal rod and gradually moves out of the limiting hole to unlock the sliding support. The longitudinal rod contacts and extrudes the locking block to move out of the limiting groove to unlock the rotating support. The hinge locking mechanism further includes an unlocking connecting rod. The unlocking connecting rod is installed on the top end of the longitudinal rod and can rotate. When the support beam simultaneously presses the two ends of the unlocking connecting rod, the unlocking connecting rod can extrude the longitudinal rod to move downward.
