Description

Technical Field

[0001] The invention belongs to the technical field of building structures, and in particular relates to a building beam-column connection structure. Background Art

[0002] Support beams and support columns for buildings are generally connected by welding or assembly. Both of these connection methods are fixed connections. Although they can ensure the stable connection between the support beams and support columns, when subjected to certain vibrations, such as the vibration caused by vehicles traveling on the road or the vibration caused by the use of equipment in the factory, the vibration will be transmitted from the ground and the support column to the connection node and the support beam in turn. Over time, it 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, which can absorb the vertical vibration and horizontal vibration 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, comprising a support beam and a support column, wherein a beam support platform is provided on one side of the support column, the support beam is horizontally installed on the beam support platform of two adjacent support columns, and further comprising a vibration absorbing mechanism, wherein the vibration absorbing mechanism is arranged between the beam end of the support beam and the beam support platform, so as to absorb vibrations in horizontal and vertical directions when the ground vibrates; the vibration absorbing mechanism comprises a friction pendulum and an elastic vibration absorbing block, wherein the elastic vibration absorbing block is installed on the beam support platform and used for absorbing vibrations in the vertical direction, and the friction pendulum is installed between the beam end of the support beam and the elastic vibration absorbing block and used for absorbing vibrations in the horizontal direction.

[0006] The vibration absorbing mechanism adopts elastic vibration absorbing blocks and friction pendulums to absorb vibrations in the vertical direction and horizontal direction respectively. The elastic vibration absorbing blocks can be thick rubber bearings. When the vibration transmitted from the ground and the support column is in the vertical direction, the elastic vibration absorbing blocks use their own elasticity to consume the vibration in this direction, play a vibration isolation role, and reduce the vertical vibration energy transmitted to the support beam. The friction pendulum includes an upper seat plate, a lower seat plate and a slider arranged between the upper seat plate and the lower seat plate. When the vibration transmitted from the ground and the support column is horizontal vibration, the support column will swing in the horizontal direction, and the lower seat plate of the friction pendulum will swing left and right together with the beam support platform on the support column. Driven by the friction force of the lower seat plate, the slider will also slide back and forth like a pendulum. In other words, relative sliding will occur between the lower seat plate and the slider, and relative sliding will also occur between the upper seat plate and the slider. The friction force generated during this sliding process will consume vibration energy to continuously reduce the horizontal vibration energy borne by the support beam. Therefore, the elastic vibration absorbing block 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. On the basis of Technical Solution 1, it also includes a sliding rotation mechanism, which 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 is flipped upward via the sliding rotation mechanism and moved in the length direction of the support beam to avoid uneven force on the friction pendulum.

[0008] 3. On the basis of Technical Solution 2, the sliding rotation mechanism includes a rotating support for supporting the flipping of the support beam and a sliding support for supporting 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 sleeved on 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, and the other end of the transverse sliding block is connected to the rotating sleeve.

[0009] 4. On the basis of technical solution 3, the slide groove of the sleeve is a cavity structure sealed at both ends, and the transverse slider is a piston block structure. The slider and the end portions of the slide groove form a sealed cavity respectively, each sealed cavity is filled with damping oil, and the transverse slider is provided with a small hole connected to the sealed cavities on both sides. When the transverse slider squeezes the damping oil in the sealed cavity on one side, the small hole on the transverse slider can slow down the speed at which the damping oil on that side flows to the sealed cavity on the other side, thereby reducing the relative movement speed between the transverse slider and the sleeve.

[0010] 5. Based on Technical Solution 3, it also includes a hinge locking mechanism, which is installed in the rotating support and the sliding support to lock the rotating support and the sliding support when the support beam and the sliding support are assembled.

[0011] 6. On the basis of technical solution 5, the hinge locking mechanism includes a locking block, a reset spring, a longitudinal rod and a transverse rod. A mounting groove is provided on the rotating shaft, a limiting groove is provided on the rotating sleeve, the limiting groove is opposite to the mounting groove, the reset spring is installed in the mounting groove, one end of the locking block is connected to the reset spring, and the other end extends out of the mounting groove and is inserted into the limiting groove to lock the rotating sleeve immobile; a "T"-shaped socket is provided on the transverse sliding block, the bottom end of the "T"-shaped socket extends toward the rotating sleeve side and communicates with the limiting groove on the rotating sleeve, and a limiting hole is provided on the sliding sleeve The limiting hole is opposite to the "T"-shaped socket, the longitudinal rod and the transverse rod are cross-crossed and fixedly connected, the longitudinal rod passes through the limiting hole and is inserted into the "T"-shaped socket, 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 immobile; when the beam end of the supporting beam moves down and aligns with the sliding sleeve, the beam end of the supporting beam contacts and squeezes 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, and the longitudinal rod contacts and squeezes 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, which is installed at the top of the longitudinal rod and can rotate. When the support beam presses down both ends of the unlocking link at the same time, the longitudinal rod can be squeezed downward. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention is described in detail below in conjunction with specific embodiments.

[0019] Figure 1 The overall structural diagram of the building beam-column connection structure of this embodiment is shown in FIG. Figure 1 As shown, the building beam-column connection structure of this embodiment includes a support beam 1, a support column 2 and a vibration absorbing mechanism 3. A beam supporting platform 21 is provided on one side of the support column 2. The support beam 1 is horizontally installed on the beam supporting platforms 21 of two adjacent support columns 2. The vibration absorbing mechanism 3 is arranged between the beam end of the support beam 1 and the beam supporting platform 21 to absorb vibrations in the horizontal and vertical directions when the ground vibrates. Figure 2 As shown, the vibration absorbing mechanism 3 includes a friction pendulum 31 and an elastic vibration absorbing block 32. The elastic vibration absorbing block 32 is installed on the beam supporting platform 21 and is used to absorb vibrations in the vertical direction. The friction pendulum 31 is installed between the beam end of the supporting beam 1 and the elastic vibration absorbing block 32 and is used to absorb vibrations in the horizontal direction.

[0020] A vibration absorbing mechanism 3 is arranged between the support column 2 and the support beam 1, which can reduce the vibration energy received by the support beam 1 and ensure the stability of the support of the support beam 1. Specifically, the vibration absorbing mechanism 3 adopts an elastic vibration absorbing block 32 and a friction pendulum 31 to absorb the vibration in the vertical direction and the vibration in the horizontal direction respectively. The elastic vibration absorbing block 32 can be a thick rubber bearing. When the vibration transmitted from the ground and the support column 2 is a vibration in the vertical direction, the elastic vibration absorbing block 32 uses its own elasticity to consume the vibration in this direction, plays a vibration isolation role, and reduces the vertical vibration energy transmitted to the support beam 1. Figure 3 FIG. 4 shows a schematic diagram of the specific structure of the friction pendulum 31 in this embodiment. Figure 3As shown, the friction pendulum 31 includes an upper seat plate 311, a lower seat plate 312 and a friction slider 313 arranged 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 vibration, the support column 2 will swing in the horizontal direction, and 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 absorbing block 32. The friction slider 313 will slide back and forth like a pendulum under the drive of the friction force of the lower seat plate 312, that is, relative sliding will occur between the lower seat plate 312 and the friction slider 313, and relative sliding will also occur 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 borne by the support beam 1. Therefore, the elastic vibration absorbing block 32 and the friction pendulum 31 can reduce the vibration fatigue of the support beam 1 and ensure the service life of the support beam 1 and the stability of the support.

[0021] After the support beam 1 is built, it is generally necessary to support other building structures, so it will bend downward in the vertical direction, which causes the end of the support beam 1 to tilt upward. Since the end of the support beam 1 is pressed on the friction pendulum 31, the force on the side of the friction pendulum 31 close to the end of the support beam 1 becomes smaller, and the force on the side away from the end of the support beam 1 becomes larger. In other words, the left and right sides of the friction pendulum 31 will be subjected to uneven force, which may cause the friction pendulum 31 to deform or tilt unexpectedly. The friction slider 313 in the friction pendulum 31 will have problems such as reduced sliding displacement and reduced sliding efficiency due to the uneven force on the left and right sides, affecting the friction energy consumption effect.

[0022] This embodiment uses a sliding rotation mechanism 4 with two degrees of freedom to solve the problem. 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 via the sliding rotation mechanism 4 and moves in the length direction of the support beam 1 to avoid uneven force on the friction pendulum 31. Specifically, the sliding rotation mechanism 4 includes a rotating support 41 for supporting the flipping of the beam 1. The rotating support 41 includes a rotating shaft support 411, a rotating sleeve 412 and a rotating shaft 413. The rotating shaft support 411 is installed on the upper side of the friction pendulum 31, and the rotating shaft 413 is installed on the rotating shaft support 411. The rotating sleeve 412 is sleeved on the rotating shaft 413 and can rotate around the rotating shaft 413. When the support beam 1 is bent vertically, the beam end of the support beam 1 will be tilted upward and the rotating sleeve 412 will be driven to flip together through the sliding support 42. At this time, the rotating shaft support 411 remains horizontal and motionless, and the friction pendulum 31 is subjected to relatively uniform force. Therefore, when the rotating support 41 provides the beam end of the support beam 1 with the freedom to flip upward, even if the beam end of the support beam is tilted upward due to the vertical load on the support beam 1, the pressure on the friction pendulum 31 is uniform, thereby ensuring the friction energy consumption effect of the friction pendulum 31. When the end of the supporting beam is tilted, the supporting beam 1 will generate a pulling force along the length direction of the supporting beam 1, that is, a downward pulling force, on the rotating support 41 due to its own gravity and the load it bears. The pulling force will be transmitted to the friction pendulum 31 via 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. A sliding groove 4211 is provided in the sliding sleeve 421. A sliding track 4212 is provided on the side wall of the sliding sleeve 421. One end of the transverse sliding block 422 passes through the sliding track 4212 on the sliding sleeve 421 and is inserted into the sliding groove 4211 of the sliding sleeve 421. The transverse sliding block 422 can move along the axis direction of the sliding groove 4211. The other end of the transverse sliding block 422 is connected to the rotating sleeve 412 are integrated, and 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, so that the beam end of the support beam 1 will move a short distance along the length direction of the support beam 1 while it is warped upward 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 supporting surface direction of the rotating support 41, and the friction pendulum 31 is still evenly stressed, ensuring the friction energy dissipation effect of the friction pendulum 31.

[0023] Since 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 will slide back and forth laterally, and at the same time, it will drive the transverse sliding block 422 in the sliding support 42 to slide back and forth laterally in the sliding groove 4211 of the sliding sleeve 421 through the rotating support 41. The superposition of these two transverse reciprocating sliding movements may make the vibration condition of the support beam 1 very complicated, and may even cause resonance between the friction pendulum 31 and the sliding support 42, resulting in an increase in the horizontal vibration amplitude of the support beam 1, just like placing two superimposed sliding blocks on the palm. When the palm moves back and forth quickly, when the top sliding block resonates with the palm, its lateral displacement is large, which means that its amplitude in the horizontal direction is increased.

[0024] In this embodiment, the sliding support 42 is designed as a hydraulic cylinder to solve the problem. Figure 3 and Figure 4 The specific structural diagram of the sliding support 42 is shown in FIG. Figure 3 and Figure 4As shown, the slide groove 4211 of the sleeve 421 of this embodiment is a cavity structure sealed at both ends, and the transverse slider 422 is a piston block structure. The transverse slider 422 and the two end portions of the slide groove 4211 respectively form a sealed cavity, each sealed cavity is filled with damping oil, and the transverse slider 422 is provided with a small hole 4221 connected to the sealed cavities on both sides. When the transverse slider 422 squeezes the damping oil in the sealed cavity on one side, 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 sealed cavity on the other side, so as to reduce the speed of relative movement between the transverse slider 422 and the sleeve 421. When the vibration frequency of the sliding support 42 is fast, the damping oil at both ends of the transverse sliding block 422 can eliminate the horizontal degree of freedom of the sliding support 42 to a certain extent. The specific implementation process is: since the transverse sliding block 422 is connected to the friction pendulum 31 via the rotating support 41, when the friction pendulum 31 moves back and forth laterally due to horizontal vibration, the transverse sliding block 422 will move back and forth with the friction pendulum 31. When the transverse sliding block 422 moves to the left with the friction pendulum 31, it will squeeze the damping oil in the left sealing chamber, and the damping oil will flow to the right sealing chamber through the small hole 4221 on the transverse sliding block 422. Since the aperture of the small hole 4221 is small, the flow speed of the damping oil can be reduced, which also reduces the transverse sliding block 422 and the sliding sleeve 4 21 relative movement speed, and when the vibration frequency is fast, the damping oil on the left side may not have time to flow to the right side, and the transverse slider 422 has changed the extrusion direction, so that the damping oil on the right side begins to flow to the left side, and this cycle is repeated. The position of the transverse slider 422 relative to the sleeve 421 is basically unchanged. At this time, the transverse slider 422 and the sleeve 421 can be regarded as one, 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 can be regarded as only one, so the consequences of the superposition of two lateral reciprocating sliding movements are avoided, and the problem of increased amplitude of the support beam 1 due to resonance is also avoided. Although the design of the small hole 4221 on the transverse slider 422 slows down the flow of the damping oil, when the beam end of the support beam 1 needs to move along its length direction, the pulling force of the support beam 1 on the sleeve 421 is continuous, and the squeezing pressure of the sleeve 421 on the damping oil on one side is also continuous. The damping oil on this side can flow to the other side through the small hole 4221 to realize the movement of the sleeve 421. In other words, the design of the damping oil between the sleeve 421 and the transverse slider 422 and the design of the small hole 4221 on the transverse slider 422 can realize the relative sliding between the sleeve 421 and the transverse slider 422 only when the squeezing pressure is a continuous force. When the squeezing pressure is an instantaneous force or the duration is short, the relative displacement between the 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 slideway 4212 at the side wall of the sleeve 421, the sleeve 421 also needs to move along the axis of the transverse slider 422, and the sleeve 421 and the transverse slider 422 are also filled with damping oil. Therefore, in order to avoid leakage of the damping oil, the structure between the transverse slider 422 and the slide groove 4211 is similar to that of a hydraulic cylinder, and the damping oil on both sides can only flow through the small holes 4221 on the transverse slider 422. At the same time, the length of the transverse slider 422 is longer than the length of the slideway 4212 to avoid leakage of the damping oil on both sides during the relative sliding of the transverse slider 422 and the sleeve 421.

[0025] Since the sliding rotation mechanism 4 has two degrees of freedom, when the support beam 1 and the sliding rotation mechanism 4 are assembled, the sliding rotation mechanism 4 is easy to rotate and move horizontally, which makes it difficult to align the mounting screw holes on the support beam 1 and the sliding rotation mechanism 4. Therefore, when the support beam 1 and the sliding rotation mechanism 4 are assembled, the 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, and the sliding rotation mechanism 4 is unlocked. Specifically, Figure 3 and Figure 4 FIG. 4 shows a schematic diagram of the hinge locking mechanism 5 before and after the rotating support 41 and the sliding support 42 are unlocked. Figure 3 and Figure 4 As shown, the hinge locking mechanism 5 of this embodiment is installed in the rotating support 41 and the sliding support 42, and the hinge locking mechanism 5 includes a locking block 51, a reset spring 52, a longitudinal rod 53 and a transverse rod 54. The rotating shaft 413 is provided with a mounting groove 4131, and the rotating sleeve 412 is provided with a limiting groove 4121. Before the rotating sleeve 412 rotates, the limiting groove 4121 is opposite to the mounting groove 4131, and the reset spring 52 is installed in the mounting groove 4131. One end of the locking block 51 is connected to the reset spring 52, and the other end extends out of the mounting groove 4131 and is inserted into the limiting groove 4121. Figure 3It can be seen that 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 and immovable; a "T"-shaped socket 4222 is provided on the transverse sliding block 422, and since the transverse sliding block 422 is integrally connected with the rotating sleeve 412, the bottom end of the "T"-shaped socket 4222 can extend toward the rotating sleeve 412 side and communicate with the limiting groove 4121 on the rotating sleeve 412, and a limiting hole 4213 is provided on the sliding sleeve 421, and when the transverse sliding block 422 is opposite to the sliding sleeve 421 Before sliding, the limiting hole 4213 is opposite to the "T"-shaped socket 4222, the longitudinal rod 53 and the transverse rod 54 are cross-crossed and fixedly connected as a whole, wherein the transverse rod 54 is arranged at a position close to the top of the longitudinal rod 53, the longitudinal rod 53 passes through the limiting hole 4213 and is inserted into the "T"-shaped socket 4222, the bottom end of the longitudinal rod 53 is aligned with the locking block 51, the top end extends out of the sliding sleeve 421, and the transverse rod 54 is in the limiting hole 4213. When the transverse sliding block 422 is not moved, the transverse rod 54 also remains in the position, so the transverse rod 54 can lock the sliding sleeve 421. Figure 4 It can be seen that when the beam end of the support beam 1 moves downward and aligns with the sliding sleeve 421, the beam end of the support beam 1 contacts and squeezes the longitudinal rod 53 to move downward, and the transverse rod 54 moves downward 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 achieve unlocking of the sliding support 42. During the downward movement, the longitudinal rod 53 contacts and squeezes 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 achieve unlocking of the rotating support 41. It should also be noted that if the longitudinal rod 53 is squeezed and moved downward for too long, 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 socket on the transverse sliding block 422 adopts a "T"-shaped socket 4222. Since the transverse sliding block 422 remains in the limited position of the rotating sleeve 412, the transverse rod 54 is gradually inserted into the "T"-shaped socket 4222 of the transverse sliding block 422 during the downward movement, until the transverse rod 54 abuts against the upper step surface of the "T"-shaped socket 4222 and no longer moves downward, thereby limiting 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, thereby realizing the unlocking of the rotating sleeve 412 without limiting the rotation angle of the rotating sleeve 412.

[0026] Since the trigger position of the hinge locking mechanism 5 is only in the middle of the top of the longitudinal rod 53, when the support beam 1 is lifted and moved downward, if the support beam 1 is tilted, its beam end is easy to trigger the unlocking of the hinge locking mechanism 5, and the sliding rotation mechanism 4 needs to be reset to continue to assemble the support beam 1, which affects the construction progress. Figure 3 and Figure 4 The unlocking link 55 is arranged at the top of the longitudinal rod 53, and a contact 551 is arranged at each end of the unlocking link 55 and extends upward. The middle position of the unlocking link 55 is movably connected with the longitudinal rod 53 and forms a lever with the connection point of the longitudinal rod 53. At the same time, a link placement groove 4214 is opened on the upper end surface of the sliding sleeve 421. The unlocking link 55 is in the link placement groove 4214 and can swing up and down. When the contact 551 at one end of the unlocking link 55 is subjected to force, the end will flip downward without driving the longitudinal rod 53 to move downward as a whole. Only when the contacts 551 at both ends of the unlocking link 55 are subjected to force at the same time will the longitudinal rod 53 be driven to move downward. Such a design can prevent the hinge locking mechanism 5 from being unlocked prematurely due to the tilt of the hoisted support beam 1. Only when the entire beam end of the support beam 1 is close to the sliding support 42 and close to horizontal, the contacts 551 at both ends of the unlocking link 55 can be pressed down at the same time to trigger the unlocking, thereby reducing the risk of mis-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 is convenient for subsequent installation.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
