Description

Technical Field

[0001] The present invention relates to the field of steel structure beam-column joint connection mechanisms, and specifically to a multi-stage shock-absorbing connection mechanism for steel structure beam-column joints. Background Art

[0002] Currently, the connection of beam-column joints in prefabricated frame structures is the key restricting the development of prefabricated frame structures. Most of the existing beam-column joints are connected by welding or multi-bolt connection, and the multi-bolt connection structure can be disassembled for reuse.

[0003] A steel structure beam-column joint connection mechanism that simply uses bolt connection or welding has poor stability during use, and is prone to loosening due to vibration and other problems when subjected to external forces. After loosening occurs, the node position cannot be emergently processed in time, leading to greater structural problems, and in severe cases, the overall collapse of the steel structure.

[0004] Therefore, how to reduce the harm of vibration when the steel structure encounters external forces on the basis of ensuring the stability of the structure connection has become an urgent problem to be solved in the field of steel structure beam-column joint connection mechanisms. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art in connecting steel structure nodes, where the connection stability is poor due to bolt connection or welding and cannot effectively cope with the harm caused by vibration. A multi-stage shock-absorbing connection mechanism for steel structure beam-column joints is provided. By using the plug-in connection form and anchoring to ensure the stability of the node connection, and using the intermediate buffer connection member to provide a vibration buffer basis for the connection of the steel structure nodes, the purpose of ensuring the stability of the structure connection and resisting vibration damage is achieved.

[0006] The purpose of the present invention is mainly achieved through the following technical solutions:

[0007] A multi-stage shock-absorbing connection mechanism for steel structure beam-column joints, including a beam member and a column member, the axes of the beam member and the column member are perpendicular to each other, and further includes an intermediate buffer connection member, both the beam member and the column member are connected to the intermediate buffer connection member;

[0008] A column connection base is fixed on the intermediate buffer connection member, and the column connection base and the column member are plugged;

[0009] A beam connection assembly is fixed on the intermediate buffer connection member, and the beam connection assembly is plugged and anchored with the beam member.

[0010] In the prior art, when connecting the beam components and column components, bolts or welding are usually used for connection. Such connection methods are convenient for disassembly, but have poor stability, so there are often risks of steel structure shaking or collapse. In order to improve the stability of steel structures, the prior art increases the number of connection points, increases the frequency of maintenance, and inspects the connection positions to ensure the overall stability of the steel structure. However, this will affect the normal use of the steel structure, thereby increasing maintenance costs.

[0011] In the present invention, an intermediate buffer connector is provided, and a column connection base and a beam connection assembly are provided on the intermediate buffer connector. The column connection base and the column component are plugged together to connect the column component and the intermediate buffer connector, and the contact area of ​​the connection position is effectively increased through plugging, thereby achieving the purpose of enhancing the connection stability. Since the column component is a component in a vertical state, its own weight can enhance the plugging stability of the column component and the column connection base in the plugged state. In the plugged state, the side of the column component can also be prevented from coming off the column connection base, thereby ensuring the plugging stability of the column component and the intermediate buffer connector.

[0012] The contact area of ​​the connection position between the beam connection assembly and the beam member is increased by plugging, thereby enhancing the plugging stability, and the integrity and connection stability of the plugging position are enhanced by anchoring, thereby enhancing the connection stability of the beam member and the beam connection assembly without the support of self-weight;

[0013] In the present invention, the insertion between the beam connection assembly and the beam member, and the insertion between the column member and the column connection base can increase the contact points of the connection position, that is, increase the contact area of ​​the connection position, thereby achieving the goal of using the intermediate buffer connector as an intermediate connection to enhance the stability of the connection between the beam member and the column member. On this basis, the intermediate buffer connector can also play a buffering role on the connection position, thereby eliminating the vibration hazard of the connection position to a certain extent.

[0014] Furthermore, a column connection plug-in is fixed on the column connection base, a column connection plate is provided on the side of the column member, and an embedded connection groove is provided on the column connection plate, and the column connection plug-in can be embedded in the embedded connection groove;

[0015] The column connecting plate and the column connecting base are connected by bolts.

[0016] In the present invention, the column connection plug-in is used to form a plug-in connection with the embedded connection groove, thereby enhancing the plug-in stability of the column member and the intermediate buffer connection piece. The column connection plate is used to increase the plug-in position of the column member and the column connection base on the side of the column member, thereby enhancing the plug-in stability of the column member and the intermediate buffer connection piece, avoiding the tendency of the column member to deviate laterally on the intermediate buffer connection piece, thereby achieving the purpose of avoiding the steel structure from tilting.

[0017] Further, the column connection plug-in comprises a plug-in base, the plug-in base is fixed on the column connection base, and a plug-in terminal is fixed on the plug-in base;

[0018] The embedded connection groove is a stepped groove, and the plug-in base and the plug-in terminal can both be embedded in the embedded connection groove;

[0019] A top notch is provided on one side of the plug-in end away from the plug-in base, a bead is provided in the top notch, a cavity is provided in the plug-in end, a base filling is provided at the bottom of the cavity, and the cavity is filled with elastic small balls;

[0020] A bulging side plate is provided on the side of the plug-in terminal. When the plug-in terminal is in a plugged state, the bulging side plate presses against the inner wall of the embedded connection groove.

[0021] In the present invention, the plug-in base is used to bear the plug-in stress, and the plug-in terminal is used to be more deeply embedded in the embedded connection groove, so as to enhance the embedding stability. The embedded connection groove is a stepped groove, so the plug-in base is based on the column connection base, and the plug-in terminal can be based on the plug-in base, so as to achieve the purpose of using the stepped groove to effectively counteract the shear stress exerted on the column connection plug-in.

[0022] On this basis, the plug-in terminal is filled with elastic balls, thereby pushing the balls out from the top notch. After the plug-in terminal is inserted into the embedded connecting groove, the balls are squeezed into the cavity, thereby squeezing the elastic balls. Due to the pressure of the column component's own weight, the elastic balls cannot push the balls out from the top notch, thereby squeezing the bulging side plates. By pressing the bulging side plates against the embedded connecting groove, the plug-in terminal can be effectively embedded in the embedded connecting groove.

[0023] On this basis, when the column component is subjected to a small external force, a buffering effect can be formed through slight deformation of the elastic balls and the bulging side plates, thereby avoiding affecting the connection position of the column component and the intermediate buffer connector.

[0024] Further, the elastic ball includes a ball wall, and a central ball is arranged inside the ball wall. A plurality of inner springs are arranged on the outer surface of the central ball. The inner springs are evenly distributed around the center of the central ball. One end of the inner spring is fixed to the central ball, and the other end is fixed to the ball wall.

[0025] In the present invention, the elastic ball forms a hollow cavity through the ball wall, so as to ensure that the elastic ball can play a buffering role when being squeezed. By using the slight deformation of the ball wall to apply an external force to the bulging side plate, the bulging side plate is made to bulge, and when the deformation amount increases through the hollow cavity, the excess deformation amount can be accommodated in the form of compressing the ball wall. This can not only avoid excessive deformation of the bulging side plate from damaging the embedded connection groove, but also provide sufficient force support for the plugging end to ensure stable plugging. It can also avoid damage to the connection position through the deformation of the ball wall when the column member shakes.

[0026] The central ball inside the ball wall can effectively provide weight for the elastic ball, thus ensuring the stability of the elastic ball. And the inner spring can enhance the elastic performance of the elastic ball, and can also maintain the overall stability of the elastic ball when the ball wall deforms, so as to achieve the purpose of guiding the elastic force and avoid uneven force on the bulging side plate caused by local accumulation of the elastic ball.

[0027] Further, the beam member includes a beam body. A beam connection end is fixed on one side of the beam body close to the intermediate buffer connection member. A connection cavity is arranged inside the beam connection end, and the beam connection assembly is inserted into the connection cavity.

[0028] A cone is fixed inside the connection cavity, and the cone is inserted into the beam connection assembly and is anchored and connected.

[0029] In the present invention, the beam body is used as the bearing foundation of the beam member. The beam connection end is used to form a plugged state with the beam connection assembly, and the beam connection assembly is accommodated through the connection cavity. The cone inside the connection cavity can be plugged into the beam connection assembly, so as to form the mutual plugging of the beam connection assembly and the beam connection end, and enhance the plugging stability of the beam connection end and the beam connection assembly.

[0030] Further, the beam connection assembly includes a cylinder body. One end of the cylinder body is fixed on the intermediate buffer connection member, and an embedded end is fixed at the other end of the cylinder body. The cylinder body is inserted into the connection cavity.

[0031] A convex block is fixed on the cone, and the convex block can be embedded into the embedded end.

[0032] A tip is fixed at the end of the cone, and the tip is inserted into the cylinder body. External threads are arranged on the outer surface of the cone, and the cylinder body is filled with anchoring filling.

[0033] In the present invention, the cylinder body is used as the insertion main body of the beam connection component to be inserted into the connection cavity, the cone is inserted into the cylinder body, an embedded end is arranged on the cylinder body, and the cone and the cylinder body can be inserted more stably by means of the convex block on the cone being embedded into the embedded end. Moreover, the tip at the end of the cone can squeeze and puncture the anchoring filling inside the cylinder body, and the external thread and the anchoring filling are mutually extruded, so that the anchoring filling can anchor the cone and the cylinder body, achieving the purpose of enhancing the insertion stability between the cone and the cylinder body, and also enhancing the connection stability between the beam connection end and the beam connection component.

[0034] Further, a plurality of limiting convex ribs are arranged on the outer surface of the cylinder body, and the limiting convex ribs are evenly distributed circumferentially around the axis of the cylinder body;

[0035] A plurality of limiting grooves are arranged on the inner wall of the connection cavity, and the number and positions of the limiting grooves correspond to the number and positions of the limiting convex ribs: each limiting groove corresponds to one limiting convex rib, and the limiting convex rib can be slidably embedded into the limiting groove.

[0036] In the present invention, the correspondence between the limiting convex ribs and the limiting grooves can effectively share the uniform degree of the insertion force after the beam connection component is inserted into the beam connection end. By means of the limiting convex rib being embedded into the limiting groove, the limiting convex rib can use the limiting groove as a guide to fix the insertion position of the beam connection component and the beam connection end. Thus, under the action of the limiting convex ribs evenly distributed circumferentially around the axis of the cylinder body, the beam connection component after being inserted into the beam connection end can be effectively prevented from shaking, thereby enhancing the overall stability of the present invention.

[0037] Further, the anchoring filling includes an outer capsule, an inner capsule is arranged inside the outer capsule, fixed anchoring particles are filled between the outer capsule and the inner capsule, and liquid anchoring agent is filled inside the inner capsule;

[0038] Both the outer capsule and the inner capsule can be squeezed and broken.

[0039] In the present invention, the outer capsule is used to wrap the solid anchoring particles, and the inner capsule is used to wrap the liquid anchoring agent. When the solid anchoring particles and the liquid anchoring agent are mixed, an anchoring effect can be formed through a chemical reaction. Therefore, when the anchoring filling is squeezed by the cone and the tip, the outer capsule and the inner capsule can be broken and an anchoring effect is generated. If the insertion of the cone in the cylinder body is unstable and problems such as shaking occur, more outer capsules and inner capsules in the anchoring filling inside the cylinder body will be broken, so that the anchoring effect is enhanced, achieving the purpose of making the insertion between the cone and the cylinder body more stable.

[0040] Furthermore, the intermediate buffer connecting member includes a central block, and the central block is filled with buffer filling;

[0041] A number of first rotating connecting rods and second rotating connecting rods are provided on the central block. One end of the first rotating connecting rod extends into the buffer filling, and the other end thereof is fixedly connected to the beam connecting assembly;

[0042] One end of the second rotating connecting rod extends into the buffer filling, and the other end thereof is fixed to the column connecting base;

[0043] Wedge-shaped ends are fixed to one ends of the first rotating connecting rod and the second rotating connecting rod that extend into the buffer filling;

[0044] One end of the first rotating connecting rod fixed to the column connecting base extends into the column member and is provided with an end plate. A number of insertion plates are provided on the end plate. The column member is filled with strengthening filling, and the strengthening filling abuts against the end plate and the insertion plates.

[0045] In the present invention, the core of the intermediate buffer connecting member is the central block. Taking the central block as the basis for connection and load bearing, a first rotating connecting rod is arranged on the central block for connecting the beam connecting assembly, and the second rotating connecting rod is used for connecting the column connecting base, so that the beam member connected by the beam connecting assembly can achieve the purpose of effectively utilizing the buffering effect of the buffer filling through the transmission of the beam connecting assembly and in combination with the wedge-shaped end of the first rotating connecting rod extending into the buffer filling. Thus, when the beam member is subjected to an external force, the shear stress in the corresponding direction on the central block can be offset by the buffer filling, avoiding damage to the steel structure joint;

[0046] The column member connected by the column connecting base can achieve the purpose of effectively utilizing the buffering effect of the buffer filling through the transmission of the column connecting base and in combination with the wedge-shaped end of the second rotating connecting rod extending into the buffer filling. Thus, when the column member is subjected to an external force, the shear stress in the corresponding direction on the central block can be offset by the buffer filling, avoiding damage to the steel structure joint;

[0047] Filling the buffer filling inside the central block can effectively apply an elastic restoring force to the first rotating connecting rod, the second rotating connecting rod and the wedge-shaped end buried in the buffer filling, thereby buffering the first rotating connecting rod, the second rotating connecting rod and the wedge-shaped end. When the column member and the beam member are inclined or rotated under the action of external forces, the wedge-shaped end can effectively squeeze the buffer filling through the deformation trend, so as to buffer and provide elastic restoring force for shaking, vibration, deflection, inclination and other situations by using the buffer filling.

[0048] Further, the buffer filling includes a plurality of outer balloons, and the outer balloons are all filled with inflatable balls.

[0049] In the present invention, the outer balloon is used to wrap the inflatable ball. By filling a plurality of inflatable balls into the outer balloon in the present invention, it can effectively avoid the loss of function caused by the breakage of some inflatable balls on the basis of providing elastic restoring force by the inflatable balls, thereby improving the long-term applicability of the present invention.

[0050] In summary, the present invention has the following beneficial effects compared with the prior art:

[0051] (1) In the present invention, by setting an intermediate buffer connector and providing a column connection base and a beam connection assembly on the intermediate buffer connector, the column member and the intermediate buffer connector are connected by inserting the column connection base and the column member, and the contact area of the connection position is effectively increased through the insertion, so as to achieve the purpose of enhancing the connection stability. Since the column member is a vertically arranged member, its own weight can enhance the insertion stability of the column member and the column connection base in the inserted state. In the inserted state, it can also prevent the side surface of the column member from disengaging from the column connection base, thus ensuring the insertion stability of the column member and the intermediate buffer connector.

[0052] (2) In the present invention, the cylinder is used as the insertion main body of the beam connection assembly to be inserted into the connection cavity, the cone is inserted into the cylinder, and an embedded end is provided on the cylinder. By embedding the convex block on the cone into the embedded end, the insertion of the cone and the cylinder can be more stable. And through the tip of the cone end, it can squeeze and puncture the anchoring filling in the cylinder, and form mutual extrusion with the anchoring filling by using the external thread, so that the anchoring filling can anchor the cone and the cylinder, achieving the purpose of enhancing the insertion stability of the cone and the cylinder, and also enhancing the connection stability of the beam connection end and the beam connection assembly when they are inserted into each other.

[0053] (3) In the present invention, a buffer filling is provided inside the central block, which can effectively apply an elastic restoring force to the first rotating connecting rod, the second rotating connecting rod and the wedge-shaped end buried in the buffer filling, thereby buffering the first rotating connecting rod, the second rotating connecting rod and the wedge-shaped end. When the column member and the beam member are inclined or rotated under the action of an external force, the wedge-shaped end can effectively squeeze the buffer filling through the deformation tendency, so as to buffer the shaking, vibration, deflection, inclination and other conditions by using the buffer filling and provide an elastic restoring force.

Specific embodiments

[0062] To make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings. The illustrative embodiments and descriptions thereof of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0063] Embodiment:

[0064] As Figures 1 to 6 shown, this embodiment relates to a multi-stage shock-absorbing connection mechanism for steel structure beam-column joints, including a beam member 1 and a column member 2, the axes of the beam member 1 and the column member 2 are perpendicular to each other, and further includes an intermediate buffer connection member 6, both the beam member 1 and the column member 2 are connected to the intermediate buffer connection member 6;

[0065] A column connection base 5 is fixed on the intermediate buffer connection member 6, and the column connection base 5 is inserted into the column member 2;

[0066] A beam connection assembly 7 is fixed on the intermediate buffer connection member 6, and the beam connection assembly 7 is inserted into and anchored to the beam member 1.

[0067] Since the connection of the steel structure beam-column node in the prior art has the problems of insufficient stability and poor shock-absorbing ability, the present embodiment abandons the simple bolt connection or welding method in the prior art, adds an intermediate buffer connector 6 to the steel structure beam-column node, and uses the intermediate buffer connector 6 as the intermediate core. The column component 2 and the beam component 1 are both plugged into the intermediate buffer connector 6. The column connection base 5 on the intermediate buffer connector 6 can be plugged into the column component 2, and the beam connection assembly 7 can be plugged into the beam component 1.

[0068] Since the steel structure itself has a large deadweight, when the column member 2 is plugged into the intermediate buffer connector 6 and the column connection base 5, the weight of the column member 2 can be used to squeeze the intermediate buffer connector 6, thereby achieving a stable plug-in connection. When the beam member 1 is plugged into the beam connection assembly 7, since there is not much deadweight available, the plug-in connection state is stabilized by the anchoring effect. In this embodiment, the plugging of the column member 2 and the column connection base 5, and the plugging of the beam member 1 and the beam connection assembly 7 can effectively increase the stress area of ​​the connection position between the column member 2 and the beam member 1. When encountering external forces, the shear stress formed by the shaking and vibration of the overall steel structure can be dispersed to a larger stress area, thereby reducing the harm of the shear stress and achieving the purpose of enhancing the stability of the plug-in connection in this embodiment.

[0069] In actual application, this embodiment can convert the multi-point connection in the prior art into an integral connection with a larger force range through the plug-in connection between the column connection base 5 and the column component 2, and the plug-in connection between the beam connection assembly 7 and the beam component 1, thereby effectively avoiding the risks of tilting, connection point breakage, collapse, etc. when the steel structure is shaken and vibrated. If the risk encountered exceeds the limit that this embodiment can cope with, this embodiment can also delay the occurrence of dangerous situations, thereby gaining more reaction time.

[0070] Furthermore, a column connection plug-in 4 is fixed on the column connection base 5, a column connection plate 523 is provided on the side of the column member 2, and an embedded connection groove 8 is provided on the column connection plate 523, and the column connection plug-in 4 can be embedded in the embedded connection groove 8;

[0071] The column connecting plate 523 and the column connecting base 5 are connected by bolts.

[0072] In practical applications of this embodiment, the column connection plate 523 is located on the side surface of the column member 2. In this embodiment, the column connection plate 523 is at least arranged on two symmetric side surfaces of the column member 2, so that the force on the column member 2 can be balanced. The insertion connection between the column connection plug-in 4 and the column member 2 can make the force on the column member 2 more balanced. The embedded connection groove 8 accommodates the column connection plug-in 4 through an engaged connection relationship, so that the column connection plug-in 4 can form a more stable insertion state with the column connection plate 523.

[0073] In order to enhance the connection stability between the column connection plate 523 and the column connection base 5, in this embodiment, the column connection plate 523 and the column connection base 5 are bolted together, so that connection points can be added on the basis of insertion and the connection can be made more stable. Bolt holes are provided on both the column connection plate 3 and the column connection base 5, and the column connection plate 3 and the column connection base 5 are bolted through the bolt holes 51. The bolt holes 51 are evenly distributed on both sides of the insertion end 44.

[0074] Furthermore, the column connection plug-in 4 includes an insertion base 47, the insertion base 47 is fixed on the column connection base 5, and an insertion end 44 is fixed on the insertion base 47;

[0075] The embedded connection groove 8 is a stepped groove, and both the insertion base 47 and the insertion end 44 can be embedded in the embedded connection groove 8;

[0076] On one side of the insertion end 44 facing away from the insertion base 47, there is a top notch 41. A bead 42 is arranged in the top notch 41. A cavity is provided in the insertion end 44, and a base filling 46 is arranged at the bottom of the cavity. The cavity is filled with elastic balls 43;

[0077] The side surface of the insertion end 44 is provided with a bulging side plate 45. When the insertion end 44 is in the insertion state, the bulging side plate 45 abuts against the inner wall of the embedded connection groove 8.

[0078] In this embodiment, since the embedded connection groove 8 is a stepped groove, the insertion end 44 can penetrate deeper into the embedded connection groove 8. The interaction force between the insertion end 44 and the embedded connection groove 8 and the interaction force between the insertion base 47 and the embedded connection groove 8 in this embodiment are relatively dispersed, so that the insertion of the column connection plug-in 4 in the embedded connection groove 8 is less likely to be damaged, achieving the purpose of enhancing the insertion effect;

[0079] In the practical application of this embodiment, the bead 42 at the top notch 41 is ejected from the cavity by the elastic ball 43 when the insertion is not completed. At this time, the bead 42 is fixed by the elastic ball 43, so the bead 42 will not come out of the top notch 41. After the insertion is completed, the weight of the column member 2 presses on the column connection plug 4. Therefore, the bead 42 can be pressed into the top notch 41 and form an extrusion on the elastic ball 43. After the elastic ball 43 is extruded, it will generate a force to eject the bead 42 from the top notch 41. In this way, if it is necessary to disassemble the column member 2, certain disassembly convenience can be provided. However, in the normal installation state, due to the self-weight of the column member 2, the bead 42 cannot be ejected from the top notch 41. Therefore, the elastic ball 43 will squeeze the bulging side plate 45, causing the bulging side plate 45 to deform through the extrusion, and forming a state of pressing against the inner wall of the embedded connection groove 8 through the deformation of the bulging side plate 45. At this time, the friction between the bulging side plate 45 and the embedded connection groove 8 increases, thereby enhancing the connection stability. And because the bulging side plate 45 is directly in contact with the elastic ball 43, when the bulging side plate 45 is subjected to an external force generated by lateral vibration or shaking, it will form a buffering effect through the elastic ball 43, achieving the purpose of forming a shock-absorbing effect for the steel structure beam-column joint.

[0080] The bulging side plate 45 in this embodiment is made of a metal plate or a plastic plate with a certain recovery ability. Since the deformation amount of the bulging side plate 45 in this embodiment is not large, the ductility and recovery ability of most metals or plastics can be effectively used to complete the extrusion effect on the embedded connection groove 8, thereby enhancing the insertion stability.

[0081] Furthermore, the elastic ball 43 includes a ball wall 431. A central ball 433 is arranged inside the ball wall 431. A plurality of inner springs 432 are arranged on the outer surface of the central ball 433. The inner springs 432 are evenly distributed around the center of the central ball 433. One end of the inner spring 432 is fixed to the central ball 433, and the other end is fixed to the ball wall 431.

[0082] In this embodiment, the ball wall 431 of the elastic ball 43 forms an elastic restoring force in the state of being internally hollow. By the mutual extrusion between the elastic balls 43, an elastic supporting force can be formed in all directions of the plug-in end 44, so as to achieve the purpose of forming an extrusion acting force on the bulging side plate 45. However, due to the extrusion of the elastic balls 43, local accumulation is likely to occur, resulting in uneven action of the elastic restoring force, so that the bulging side plate 45 cannot form a uniform extrusion action on the embedded connection groove 8. In this embodiment, a central ball 433 is arranged in the ball wall 431 of the elastic ball 43 as a fulcrum to balance the weight of the elastic ball 43, and the inner spring 432 is used to enhance the elastic restoring force of the elastic ball 43 in the defined direction, so as to enhance the uniformity of the elastic restoring force of the elastic ball 43 on the basis of enhancing the elastic restoring ability of the elastic ball 43, so that the elastic ball 43 can apply a more uniform acting force to the bulging side plate 45.

[0083] Further, the beam member 1 includes a beam body 11. A beam connection end 16 is fixed on one side of the beam body 11 close to the intermediate buffer connector 6. A connection cavity 12 is provided in the beam connection end 16, and the beam connection assembly 7 is inserted into the connection cavity 12;

[0084] A cone 13 is fixed in the connection cavity 12, and the cone 13 is inserted into the beam connection assembly 7 and is fixedly connected.

[0085] In this embodiment, the beam body 11 of the beam member 1 is used to carry the beam connection end 16. The beam connection end 16 is inserted into the beam connection assembly 7 on the intermediate buffer connector 6 to form a connection state. The connection cavity 12 of the beam connection end 16 is used to accommodate the insertion of the beam connection assembly 7, and the beam connection assembly 7 and the beam connection end 16 are in a mutually inserted state by the way that the cone 13 is inserted into the beam connection assembly 7, which can not only make the insertion state of the beam connection assembly 7 and the beam connection end 16 more stable, but also effectively enhance the mutual supporting ability of the beam connection assembly 7 and the beam connection end 16, so that the connection state between the beam member 1 and the intermediate buffer connector 6 is more stable.

[0086] Further, the beam connection assembly 7 includes a cylinder body 73. One end of the cylinder body 73 is fixed on the intermediate buffer connector 6, and an embedded end 71 is fixed at the other end of the cylinder body 73. The cylinder body 73 is inserted into the connection cavity 12;

[0087] A convex block 19 is fixed on the cone 13, and the convex block 19 can be embedded into the embedded end 71;

[0088] A tip 18 is fixed to the end of the cone 13. The tip 18 is inserted into the cylinder 73. An external thread 17 is provided on the outer surface of the cone 13. The cylinder 73 is filled with an anchoring filler 74.

[0089] Furthermore, the anchoring filler 74 includes an outer capsule 741. An inner capsule 744 is provided inside the outer capsule 741. Fixing and anchoring particles 742 are filled between the outer capsule 741 and the inner capsule 744. A liquid anchoring agent 743 is filled inside the inner capsule 744;

[0090] Both the outer capsule 741 and the inner capsule 744 can be squeezed and broken.

[0091] In this embodiment, the bump 19 on the cone 13 is inserted into the cylinder 73 along with the cone 13 and is embedded in the embedded end 71. The tip 18 of the cone 13 punctures the anchoring filler 74. At this time, the outer capsule 741 and the inner capsule 744 in the anchoring filler 74 are broken during the squeezing of the cone 13 and the puncturing of the tip 18. The solid anchoring particles and the liquid anchoring agent 743 can be effectively mixed to produce an anchoring effect. The external thread 17 on the cone 13 can effectively improve the stability of the anchoring effect.

[0092] In this embodiment, the cone 13 is fixed to the connection cavity 12 by a torsion spring 14, thereby providing a certain lateral rotation ability for the cone 13. When the beam member 1 is affected by a deflecting force, the cone 13 can provide partial restoring ability through the torsion spring 14, thereby avoiding direct hard confrontation between the cone 13 and the cylinder 73 and reducing the risk of connection node fracture caused by vibration or shaking.

[0093] During the puncturing and squeezing process, not all of the outer capsules 741 and inner capsules 744 of the anchoring filler 74 are broken. Therefore, when the steel structure in this embodiment experiences shaking or vibration, a greater degree of squeezing effect will be formed, so that more of the outer capsules 741 and inner capsules 744 of the anchoring filler 74 will be broken, thereby achieving the purpose of strengthening the anchoring effect.

[0094] Furthermore, a number of limiting convex ribs 72 are provided on the outer surface of the cylinder 73. The limiting convex ribs 72 are evenly distributed circumferentially around the axis of the cylinder 73;

[0095] A number of limiting grooves 15 are provided on the inner wall of the connection cavity 12. The number and positions of the limiting grooves 15 correspond to the number and positions of the limiting convex ribs 72: each limiting groove 15 corresponds to one limiting convex rib 72, and the limiting convex rib 72 can slide and be embedded in the limiting groove 15.

[0096] In this embodiment, the corresponding arrangement of the limiting convex ribs 72 and the limiting grooves 15 can effectively share the uniform degree of the insertion force received after the beam connection assembly 7 is inserted into the beam connection end 16. By embedding the limiting convex ribs 72 into the limiting grooves 15, the limiting convex ribs 72 can use the limiting grooves 15 as a guide to fix the insertion position of the beam connection assembly 7 and the beam connection end 16. Thus, under the action of the limiting convex ribs 72 evenly distributed circumferentially around the axis of the cylinder body 73, it can effectively prevent the beam connection assembly 7 from shaking after being inserted into the beam connection end 16, thereby enhancing the overall stability of this embodiment.

[0097] Furthermore, the intermediate buffer connecting member 6 includes a central block 62, and a buffer filling 61 is filled in the central block 62;

[0098] A number of first rotating connecting rods 64 and second rotating connecting rods 68 are provided on the central block 62. One end of the first rotating connecting rod 64 extends into the buffer filling 61, and the other end thereof is fixedly connected to the beam connection assembly 7;

[0099] One end of the second rotating connecting rod 68 extends into the buffer filling 61, and the other end thereof is fixed to the column connection base 5;

[0100] Wedge-shaped ends 63 are fixed to one ends of the first rotating connecting rod 64 and the second rotating connecting rod 68 that extend into the buffer filling 61;

[0101] One end of the first rotating connecting rod 64 fixed to the column connection base 5 extends into the column member 2 and is provided with an end plate 65. A number of insertion plates 66 are provided on the end plate 65. A strengthening filling 67 is filled in the column member 2, and the strengthening filling 67 abuts against the end plate 65 and the insertion plates 66.

[0102] Furthermore, the buffer filling 61 includes a number of outer balloons 611, and each outer balloon 611 is filled with a balloon filling 612.

[0103] In this embodiment, the core of the intermediate buffer connecting member 6 is the central block 62. Taking the central block 62 as the basis for connection and load bearing, a first rotating connecting rod 64 is arranged on the central block 62 to connect the beam connecting assembly 7, and a second rotating connecting rod 68 is used to connect the column connecting base 5. Thus, the beam member 1 connected by the beam connecting assembly 7 can reach the purpose of effectively utilizing the buffering effect of the buffer filling 61 through the transmission of the beam connecting assembly 7 and combining with the wedge-shaped end 63 extending into the buffer filling 61. Therefore, when the beam member 1 is subjected to an external force, the shear stress in the corresponding direction on the central block 62 can be offset by the buffer filling 61, avoiding damage to the steel structure joint;

[0104] The column member 2 connected by the column connecting base 5 can reach the purpose of effectively utilizing the buffering effect of the buffer filling 61 through the transmission of the column connecting base 5 and combining with the second rotating connecting rod 68 extending into the buffer filling 61. Thus, when the column member 2 is subjected to an external force, the shear stress in the corresponding direction on the central block 62 can be offset by the buffer filling 61, avoiding damage to the steel structure joint;

[0105] Filling the buffer filling 61 in the central block 62 can effectively apply an elastic restoring force to the first rotating connecting rod 64, the second rotating connecting rod 68, and the wedge-shaped end 63 buried in the buffer filling 61, thereby playing a buffering role for the first rotating connecting rod 64, the second rotating connecting rod 68, and the wedge-shaped end 63. When the column member 2 and the beam member 1 are subjected to external forces and tend to tilt, rotate, etc., the wedge-shaped end 63 can effectively squeeze the buffer filling 61 through the deformation trend, so as to achieve the function of using the buffer filling 61 to buffer and provide an elastic restoring force for situations such as shaking, vibration, deflection, and tilt.

[0106] The connection between the end plate 65 and the first rotating connecting rod 64 can effectively feedback the external influence received by the column member 2 into the buffer filling 61 of the intermediate buffer connecting member 6. And through the fixation of the end plate 65 and the extension of the insertion plate 66, the force of the column member 2 can be more effectively fed back to the first rotating connecting rod 64, so that the buffer filling 61 can play a greater role in resisting the influence of external forces on the column member 2.

[0107] In this embodiment, the outer balloon 611 is used to wrap the inflatable ball 612. The present invention fills a plurality of inflatable balls 612 into the outer balloon 611, which can effectively avoid the loss of function caused by the damage of some inflatable balls 612 on the basis of using the inflatable balls 612 to provide an elastic restoring force, thereby improving the long-term applicability of the present invention.

[0108] In this embodiment, the base filling 46 can be fixedly connected to the bottom of the bulging side plate 45, thereby preventing the bottom of the bulging side plate 45 from breaking and causing the elastic balls 43 to leak out from the bottom of the bulging side plate 45.

[0109] The solid anchoring particles 742 and the liquid anchoring agent 743 applied in this embodiment adopt the anchoring products in the prior art, so that this embodiment can be applied on a large scale.
