Description

Technical Field

[0001] The present invention relates to the technical field of wooden structure buildings, in particular to a wooden structure beam-column connection structure. Background Art

[0002] The beam-column connection structure is a vital component of the building structure. Its function is to firmly connect the beams and columns, transfer loads (such as vertical force, horizontal force, bending moment and shear force), and ensure the stability and safety of the overall structure.

[0003] Especially for wooden beams and columns, the compressive and tensile strength of wooden beams and columns are much lower than those made of reinforced concrete. Wooden beams and columns themselves are difficult to bear large loads. Under the influence of harsh environmental factors such as earthquakes and strong winds, the connection structure of wooden beams and columns is prone to damage, fracture, bending and deformation, affecting the safety and stability of the overall building structure.

[0004] In addition to the low strength of the wood material itself, which makes it difficult to withstand excessive loads, there is an inevitable gap between the contact points of the columns and beams due to the connection between the two relative surfaces. At the same time, the connection points between the columns and beams are the points where the forces on the beams and columns are relatively concentrated. Under the action of dynamic loads such as earthquakes and strong winds, the columns and beams are prone to separation. Therefore, the wooden structure beam-column connection structure is the "weak link" in the design of wooden structures. In addition, the transmission of load vibrations between beams and columns will also cause large-scale damage to the overall building structure. It is necessary to strengthen the reliability of the connection between columns and beams and absorb and disperse external vibrations to ensure the stability of wooden structures.

[0005] Therefore, the design of the wooden structure beam-column connection structure needs to comprehensively consider its connection stability and shock absorption performance design from multiple aspects, such as achieving reliable connection, absorbing vibration energy, preventing beams and columns from being deformed by force, and post-earthquake recovery. There is currently no wooden structure beam-column connection structure integrating the above functions in the existing technology. The wooden structure beam-column connection structure in the existing technology has the problems of poor connection reliability and poor shock absorption effect. As people's requirements for the quality of wooden structure buildings are increasing, the current wooden structure beam-column connection structure cannot meet the higher reliability, safety, stability and anti-collapse performance requirements of wooden structure buildings. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that the existing technology does not have a wooden structure beam-column connection structure that integrates reliable connection, absorbs vibration energy, prevents beams and columns from being subjected to stress and deformation, and recovers after an earthquake. The existing wooden structure beam-column connection structure has the problems of poor connection reliability and poor shock absorption effect. As people's requirements for the quality of wooden structure buildings are increasing, the current wooden structure beam-column connection structure cannot meet the higher reliability, safety, stability and anti-collapse performance requirements of wooden structure buildings.

[0007] In order to solve the above technical problems, an embodiment of the present invention provides a wooden structure beam-column connection structure, comprising a column connection part, a beam connection part, and an intermediate shock-absorbing part connecting the column connection part and the beam connection part. The column connection part is fixed to the top of the column, and the beam connection part is fixed to the end of the beam; and the intermediate shock-absorbing part comprises a mounting base and a first shock-absorbing assembly and an elastic shock-absorbing assembly fixedly connected to the mounting base. The mounting base comprises a pair of connecting plates spaced apart from each other along the extension direction of the beam, and the pair of connecting plates are detachably fixedly connected to the corresponding ends of the column connection part and the beam connection part respectively; the first shock-absorbing assembly is arranged between the pair of connecting plates along the circumference of the pair of connecting plates, and the two ends are respectively fixedly connected to the corresponding one of the connecting plates, and a shock-absorbing space is formed between the first shock-absorbing assembly and the pair of connecting plates; the elastic shock-absorbing assembly is arranged in the shock-absorbing space, and the two ends of the elastic shock-absorbing assembly are respectively fixedly connected to the corresponding one of the connecting plates.

[0008] With the above technical solution, the intermediate shock-absorbing portion disposed between the column connection portion and the beam connection portion is the core structure that performs a shock-absorbing function. The intermediate shock-absorbing portion can absorb vibration energy when affected by seismic waves, allowing the seismic energy to dissipate here and reducing the transmission of seismic energy between the column and the beam. The intermediate shock-absorbing portion can also provide a reverse damping force for the connection between the column and the beam to prevent the two from breaking, thereby enhancing the stability of the connection structure. The intermediate shock-absorbing portion can also provide a reverse restoring tension after a slight deflection occurs between the column and the beam, restoring the structure to its original state. Specifically, the intermediate shock-absorbing portion includes multiple components, such as a mounting base, a first shock-absorbing component, and an elastic shock-absorbing component. The two connecting plates of the mounting base serve as the mounting base for the other shock-absorbing components. The first shock-absorbing assembly can absorb seismic shear waves, thereby reducing the energy transfer of seismic waves. By surrounding the first shock-absorbing assembly between a pair of connecting plates along the circumference of the pair of connecting plates, the first shock-absorbing assembly can absorb seismic energy in multiple directions along the circumference of the pair of connecting plates. The shock-absorbing space formed by the first shock-absorbing assembly and the pair of connecting plates can also provide installation space for the elastic shock-absorbing assembly, making the spatial layout reasonable and compact. When there is a tendency for fracture between the beam and the column due to the influence of seismic waves, the elastic shock-absorbing assembly prevents the fracture of the two by overcoming the damping force of elastic deformation. It can also provide reverse recovery tension after a slight misalignment deformation occurs between the column and the beam, so that the structure returns to its original state. Therefore, compared with the existing technology, the wooden structure beam-column connection structure of this scheme can integrate the functions of absorbing vibration energy, preventing beams and columns from being deformed by force, and post-earthquake recovery. It has a better shock-absorbing effect and can meet the higher reliability, safety, stability and anti-collapse performance requirements of wooden structure buildings.

[0009] According to another specific embodiment of the present invention, the embodiment of the present invention discloses a wooden structure beam-column connection structure, and the elastic shock-absorbing assembly includes elastic cable components arranged in pairs in the shock-absorbing space; the two ends of each elastic cable component are respectively fixedly connected to a corresponding connecting plate and extend obliquely relative to the vertical direction; and each pair of elastic cable components extend crosswise with each other relative to the vertical direction.

[0010] The above technical solution, by angling the elastic cable components within the shock-absorbing space, not only absorbs some of the longitudinal seismic waves, but also provides a counter-deformation force when the beam is deformed by bending moment, limiting its upward or downward deflection. Arranging the elastic cable components in pairs and crossing each other helps maintain force balance across the entire structure.

[0011] Beneficial effects of the present invention:

[0012] The column connection part and the beam connection part are the connection basis of the wooden structure beam-column connection structure provided by the present invention. The middle shock-absorbing part is the core structure that plays a shock-absorbing role. In the middle shock-absorbing part, the two connecting plates of the mounting base are the mounting basis of other shock-absorbing components. The first shock-absorbing component can absorb seismic shear waves, thereby reducing the energy transfer of seismic waves. By arranging the first shock-absorbing component between a pair of connecting plates along the circumference of a pair of connecting plates, on the one hand, the first shock-absorbing component can absorb seismic energy in multiple directions along the circumference of the pair of connecting plates. The shock-absorbing space formed by the first shock-absorbing component and the pair of connecting plates can also provide installation space for the elastic shock-absorbing component, making the spatial layout reasonable and compact. When there is a tendency for the beam and the column to break due to the influence of seismic waves, the elastic shock-absorbing component prevents the two from breaking by overcoming the damping force of elastic deformation. It can also provide reverse recovery tension after a slight deflection occurs between the column and the beam, so that the structure returns to its original state. Therefore, compared with the existing technology, the wooden structure beam-column connection structure of this scheme can integrate the functions of absorbing vibration energy, preventing beams and columns from being deformed by force, and recovering after an earthquake. Its shock absorption effect is better and can meet the higher reliability, safety, stability and anti-collapse performance requirements of wooden structure buildings.

[0035] The connection structure between wooden beams and columns is the "weak link" in the design of wooden structures. Moreover, the transmission of load vibrations between beams and columns will cause large-scale damage to the overall building structure. It is necessary to strengthen the connection reliability between columns and beams and absorb and disperse external vibrations to ensure the stability of wooden structures.

[0036] Common forms of failure in wooden beam-column connection structures include: when the shear resistance of the wooden beam-column connection is insufficient, under the action of shear force, oblique cracks will appear between the beam-column connection surfaces. As the load increases, the cracks continue to develop, eventually leading to the fracture of the connection between the beam and column and the loss of bearing capacity. This form of failure is usually brittle and poses a greater threat to the safety of the building structure; if the bending resistance of the beam end is insufficient, bending cracks will appear at the beam end at the connection. As the cracks develop, the beam end will yield and the beam will lose its bending resistance. Although this form of failure has a certain ductility, it will also affect the normal use and safety of the connection structure; the column end may also be damaged at the node due to excessive vertical load, resulting in a decrease in the bearing capacity of the column, affecting the stability of the entire building structure.

[0037] Therefore, when a timber structure is subjected to excessive loads, when the load on the beams or columns is transferred to the timber beam-column connection, it is necessary to absorb and dissipate some of the vibration energy here to minimize the transfer of destructive energy. At the same time, the timber beam-column connection structure is also required to have strong connection reliability to constrain the relative displacement of the beams and columns, maintain the geometric relationship between the components, and ensure the overall structural rigidity. The reliability and safety design of the timber beam-column connection structure directly affects the stability, safety, and durability of the building structure.

[0038] In summary, the seismic design of timber buildings requires consideration of the stress characteristics of timber beam-column connections under earthquakes or strong winds, such as repeated shear and bending moments. Through proper design, timber beam-column connections should possess sufficient ductility and energy dissipation capacity to prevent damage during earthquakes or strong winds, ensuring the stability, safety, and durability of the building structure.

[0039] There is currently no wooden beam-column connection structure in the existing technology that integrates reliable connection, absorbs vibration energy, prevents beams and columns from being subjected to stress and deformation, and has post-earthquake recovery functions. The wooden beam-column connection structure in the existing technology has problems of poor reliability and poor shock absorption effect. As people's requirements for the quality of wooden structure buildings are increasing, the current wooden beam-column connection structure cannot meet the higher reliability, safety, stability and anti-collapse performance requirements of wooden structure buildings.

[0040] In response to the above problems, the present invention provides a wooden structure beam-column connection structure that integrates the functions of absorbing vibration energy, preventing beams and columns from being deformed by force, and post-earthquake recovery. It has a better shock absorption effect and can meet the higher reliability, safety, stability and anti-collapse performance requirements of wooden structure buildings.

[0041] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

[0042] Example 1

[0043] Embodiment 1 of the present invention provides a wooden structure beam-column connection structure, such as Figure 1 As shown, it includes a column connection part 1 and a beam connection part 2. The column connection part 1 and the beam connection part 2 are the connection basis of the wooden structure beam-column connection structure. The column connection part 1 is fixed to the top of the column 4, and the beam connection part 2 is fixed to the end of one side of the beam 5 close to the column 4. The opposite surfaces of the column connection part 1 and the beam connection part 2 can be connected through the intermediate shock-absorbing part 3. The specific structure of the column connection part 1 and the beam connection part 2 will be introduced later.

[0044] First of all, it should be noted that the external vibration loads on the wooden structure beam-column connection structure mainly include earthquakes, strong winds, etc. The earthquake loads mainly include horizontal loads and longitudinal loads. The loads of strong winds on wooden structures are mainly transverse loads, and the destructive effects and hazards of earthquake loads are stronger than those of strong winds. The horizontal loads (mainly seismic transverse waves) in earthquake scenarios are more destructive to wooden structures than the longitudinal loads (mainly seismic longitudinal waves). Therefore, in this embodiment 1, the scenario where wooden structures are affected by earthquake loads is taken as an example to introduce the various shock-absorbing components of the wooden structure beam-column connection structure.

[0045] The middle shock absorbing part 3 arranged between the column connecting part 1 and the beam connecting part 2 is the core structure that plays a role in shock absorption. Figure 1 and Figure 2 As shown, the middle shock-absorbing part 3 includes a first shock-absorbing component 31 and an elastic shock-absorbing component 32. The first shock-absorbing component 31 is a structural component with shock-absorbing performance, for example, it can be a connecting web with an arc-shaped energy-absorbing cover plate, or it can be an energy-absorbing layer structure composed of a multi-layer plate structure; when the horizontal load is transmitted to the middle shock-absorbing part 3, the seismic energy can be dissipated here, reducing the transmission of seismic energy between the column 4 and the beam 5. In addition, the first shock-absorbing component 31 should also have certain supporting performance, which can provide reliable support between the column 4 and the beam 5, increase the connection stability between the two, and prevent the beam and column from being squeezed and deformed; the elastic shock-absorbing component 32 is a structural component with a certain elastic deformation ability Parts, such as springs, stretchable and deformable rope structures, etc.; when the columns 4 and beams 5 are affected by earthquake loads and produce shear fracture or bending deformation tendencies, the elastic potential energy of the elastic shock-absorbing component 32 can absorb part of the energy, and its restoring force to overcome the elastic deformation can be used to provide a reverse damping force for the connection between the columns 4 and beams 5 to prevent the two from breaking or relative deflection, thereby limiting the deformation of the beams and columns due to compression and enhancing the stability of the wooden structure beam-column connection structure; the deformation recovery force of the elastic shock-absorbing component 32 can also provide a reverse recovery tension after a slight deflection or crack occurs between the columns 4 and beams 5, so that the wooden structure beam-column connection structure can be restored to its original state not affected by the earthquake.

[0046] To sum up, the intermediate shock-absorbing part 3 including the first shock-absorbing component 31 and the elastic shock-absorbing component 32 integrates the functions of reliable connection, absorption of vibration energy, prevention of stress deformation of beams and columns, and post-earthquake recovery, which can meet the higher reliability, safety, stability and anti-collapse performance requirements of wooden structure buildings.

[0047] Further, if Figure 1 and Figure 2As shown, the middle shock absorbing part 3 further includes a mounting base 30, which includes a pair of connecting plates 300 spaced apart from each other along the extending direction of the cross beam 5. The pair of connecting plates 300 is the mounting base for other shock absorbing components. The two opposite sides of the two connecting plates 300 can be connected to the column 4 and the cross beam 5 respectively. The opposite sides of the two connecting plates 300 can be connected to other components for shock absorption (for example, see Figure 1 The first shock absorbing assembly 31 and Figure 2 The pair of connecting plates 300 are respectively connected to the corresponding ends of the column connecting portion 1 and the crossbeam connecting portion 2 in a detachable fixed manner. The intermediate shock absorbing portion 3 is relatively small in size. When the intermediate shock absorbing portion 3 is severely damaged, the detachable connection facilitates the replacement of the intermediate shock absorbing portion 3 from between the column 4 and the crossbeam 5. Specifically, threaded holes can be provided at the ends of the connecting plates 300 and the corresponding connecting portions, and detachable connections can be achieved by bolts. Alternatively, connectors protruding toward the column 4 and crossbeam 5 can be provided on the opposite surfaces of the connecting plates 300, and slots can be provided at the corresponding ends of the column 4 and crossbeam 5 to achieve detachable connections by plugging.

[0048] It should be noted that the shape of the connecting plate 300 can be adjusted according to the cross-sectional shape of the connecting end surface of the column 4 and the beam 5. For example, when the connecting end surface of the column 4 and the beam 5 is rectangular, the corresponding connecting plate 300 can be set to a rectangular shape. When the connecting end surface of the column 4 and the beam 5 is circular, the corresponding connecting plate 300 can be set to a circular plate structure. Of course, it can also be set to other irregular shapes.

[0049] The first shock absorbing assembly 31 is disposed between a pair of connecting plates 300, with its two ends fixedly connected to a corresponding connecting plate 300. When earthquake waves are transmitted to the first shock absorbing assembly 31, they can be absorbed by the first shock absorbing assembly 31 using its shock absorbing properties, thereby dispersing energy consumption and effectively reducing the transmission of earthquake waves (especially shear earthquake waves), thereby preventing earthquake waves from causing serious damage to the beam 5 or column 4. Furthermore, the first shock absorbing assembly 31 is disposed between the pair of connecting plates 300 along the circumference of the pair of connecting plates 300. For example, the first shock absorbing assembly 31 can be disposed along the circumferential edge of each connecting plate 300, as shown in FIG. Figure 1 As shown, the first shock absorbing assembly 31 is arranged in the upper, lower, front and rear directions of the space between the two connecting plates 300 along the width direction of the crossbeam 5, so that a shock absorbing space 34 is formed between the first shock absorbing assembly 31 and the pair of connecting plates 300. The shock absorbing space 34 is as shown in FIG. Figure 2As shown, this arrangement enables the first shock-absorbing assembly 31 to absorb seismic energy from multiple directions (i.e., circumferentially around the connecting plate 300), resulting in a wider energy absorption area for improved energy absorption. Furthermore, the shock-absorbing space 34 formed by the first shock-absorbing assembly 31 and the pair of connecting plates 300 also provides mounting space for the elastic shock-absorbing assembly 32, resulting in a more rational and compact spatial layout for the intermediate shock-absorbing portion 3.

[0050] It should be noted that the first shock-absorbing component 31 can be set to a block structure, a plate structure, a strip structure or a tile structure, etc. In order to leave enough installation space for the elastic shock-absorbing component 32, the shape of the first shock-absorbing component 31 in this embodiment is preferably set to a plate structure.

[0051] like Figure 2 As shown, the elastic shock-absorbing component 32 is arranged in the shock-absorbing space 34. The elastic shock-absorbing component 32 has elastic tensile deformation ability and damping force to overcome elastic tension. Therefore, the two ends of the elastic shock-absorbing component 32 are respectively fixedly connected to a corresponding connecting plate 300. When the column 4 and the beam 5 are affected by the earthquake load and produce shear fracture or bending deformation tendency, the elastic potential energy of the elastic shock-absorbing component 32 can absorb part of the energy, and its restoring force to overcome elastic deformation can also be used to provide a reverse damping force for the connection between the column 4 and the beam 5 to prevent the two from breaking or relative deflection, thereby limiting the deformation of the beam and column due to compression and enhancing the stability of the wooden structure beam-column connection structure; the deformation recovery force of the elastic shock-absorbing component 32 can also provide reverse recovery tension after a slight deflection or crack occurs between the column 4 and the beam 5, so that the wooden structure beam-column connection structure can be restored to its original state without being affected by the earthquake.

[0052] It should be noted that the elastic shock-absorbing component 32 can specifically be a strip structure, a columnar structure, a rod structure or a plate structure. The elastic shock-absorbing component 32 can be horizontally extended in the shock-absorbing space 34, or can be inclined and extended relative to the vertical direction. When the elastic shock-absorbing component 32 is horizontally set in the shock-absorbing space 34, the deformation recovery force of the elastic shock-absorbing component 32 is a horizontal force. When the elastic shock-absorbing component 32 is inclined relative to the vertical direction in the shock-absorbing space 34, the deformation recovery force of the elastic shock-absorbing component 32 is a force inclined relative to the vertical direction.

[0053] It should also be noted that the first shock absorbing assembly 31 and the elastic shock absorbing assembly 32 can be connected to the corresponding connecting plate 300 by welding, bonding, screwing or riveting.

[0054] In one embodiment of the present invention, Figure 1 and Figure 2As shown, when each connecting plate 300 is configured as a rectangular plate structure, the four sides of the rectangular plate structure can be used to connect to the corresponding first shock absorbing assembly 31. In addition, the first shock absorbing assembly 31 can include a pair of first layered energy absorbing components 310 spaced apart from each other. The layered structure can be arranged parallel to the edge of the connecting plate 300, so that the spatial distribution is more uniform, and the shock absorption and energy dissipation can also be uniformly performed. The two ends of each first layered energy absorbing component 310 are respectively fixedly connected to the inner wall of a corresponding connecting plate 300. When viewed along the extension direction of the crossbeam 5, the pair of first layered energy absorbing components 310 can be respectively arranged on the upper and lower sides of the shock absorbing space 34, or can be respectively arranged on the left and right sides of the shock absorbing space 34.

[0055] like Figure 1 As shown, the first shock absorbing assembly 31 may further include a pair of second layered energy absorbing components 311 spaced apart from each other (due to Figure 1 The reason for the perspective occlusion in Figure 1 Only one of the second layered energy absorbing components 311 is shown in the figure. Setting the second layered energy absorbing component 311 as a layered structure allows it to be set parallel to the edge of the connecting plate 300, with a more uniform distribution in space. It can also uniformly absorb shock and dissipate energy during shock absorption and can also provide stable support on the periphery of the shock absorption space 34. The two ends of each second layered energy absorbing component 311 can be fixedly connected to the inner wall of a corresponding connecting plate 300. When viewed along the extension direction of the crossbeam 5, a pair of second layered energy absorbing components 311 can be respectively set on the upper and lower sides of the shock absorption space 34, or on the left and right sides of the shock absorption space 34. For example Figure 1 As shown, a pair of second layered energy-absorbing components 311 can be arranged on the upper and lower sides of the shock-absorbing space 34, and each second layered energy-absorbing component 311 extends parallel to the horizontal plane; a pair of first layered energy-absorbing components 310 can be arranged on the left and right sides of the shock-absorbing space 34, and each first layered energy-absorbing component 310 extends parallel to the vertical plane.

[0056] It should be noted that, in order to further improve the energy absorption efficiency of the first layered energy absorbing component 310, multiple pairs of first layered energy absorbing components 310 may be provided, for example, Figure 1 In the illustrated structure, three pairs of first layered energy-absorbing components 310 are disposed on the left and right sides of the shock-absorbing space 34. The first layered energy-absorbing components 310 on each side are arranged vertically in sequence. Of course, two, four, or other pairs of first layered energy-absorbing components 310 can also be provided. The number of second layered energy-absorbing components 311 can also be increased to two, three, or four pairs, depending on shock absorption needs.

[0057] Further, if Figure 3 and Figure 4As shown, the first layered energy-absorbing component 310 can specifically include a first core plate 3100 and a pair of first restraining members 3101 stacked along the thickness direction of the first layered energy-absorbing component 310. Among them, the first core plate 3100 is a plate-like structure extending along the length direction of the beam 5. The first core plate 3100 has a certain rigidity and can play a rigid supporting role between the two connecting plates 300, preventing the column 4 and the beam 5 from deforming to a certain extent, so that a highly reliable and non-breakable connection structure is formed between the two connecting plates 300, thereby improving the stability and reliability of the wooden structure beam-column connection structure. At the same time, the first core plate 3100 also has a certain ability to absorb energy and avoid the transmission of seismic loads. Therefore, the first core plate 3100 can not only play a stable supporting role for the connection between the column 4 and the beam 5, but also absorb a certain amount of energy when affected by vibration, thereby achieving energy consumption. In order to prevent the first core plate 3100 from bending and deforming under pressure, it is necessary to set components to limit its deformation on both sides of the first core plate 3100, namely a pair of first constraint members 3101, and each first constraint member 3101 is set to extend along the length direction of the first core plate 3100. Each first constraint member 3101 can be detachably connected to the first core plate 3100 by cooperating with bolts 3106 and second mounting holes 3105.

[0058] It should be noted that the first core plate 3100 can be made of memory alloy mild steel material, and the first constraint member 3101 can be made of steel material with a harderness higher than that of the memory alloy mild steel material. The first constraint member 3101 can be a plate-like structure or a strip-like structure. In order to cover the first core plate 3100 with as much area as possible to limit the deformation of the first core plate 3100, the first constraint member 3101 is preferably configured as follows: Figure 3 and Figure 4 The plate-like structure shown.

[0059] Further, see again Figure 3 and Figure 4 The first layered energy-absorbing component 310 can also include a pair of first elastic layers 3102 arranged on both sides of the first core panel 3100, that is, a first elastic layer 3102 is arranged between the first core panel 3100 and the corresponding first constraint member 3101. The first elastic layer 3102 has a strong energy absorption capacity, and the first elastic layer 3102 can also dissipate and absorb energy through the cutting effect when the adjacent first core panel 3100 and the first constraint member 3101 are affected by horizontal loads, thereby reducing the energy transmitted by the horizontal load to the adjacent column 4 or beam 5 through the intermediate shock-absorbing part 3, thereby reducing vibration transmission, preventing deformation, and improving the anti-collapse performance of the wooden structure beam-column connection structure.

[0060] It should be noted that the shearing effect refers to the relative displacement between the steel first core plate 3100, the first restraining member 3101, and the first elastic layer 3102 when subjected to horizontal loads (such as seismic shear waves). This causes the first elastic layer 3102 to be stretched or compressed obliquely. Simultaneously, the rigidity of the steel plate (the first restraining member 3101 and the first core plate 3102) limits the free deformation of the first elastic layer 3102, forcing high shear stresses within the first elastic layer 3102. The repeated shearing between the steel plate and the first elastic layer 3102 generates frictional heat in the first elastic layer 3102, converting mechanical energy into thermal energy, thereby dissipating energy. The first elastic layer 3102 can be made of rubber.

[0061] The steel plate and the first elastic layer 3102 can be bonded to ensure deformation coordination and prevent interlayer slip failure. Figure 4 As shown, a first mounting hole 3103 penetrating along the thickness direction of the first layered energy-absorbing component 310 can also be opened on the first core plate 3100, and a protrusion 3104 adapted to the first mounting hole 3103 can be protruded on the surface of each first elastic layer 3102 opposite to the first core plate 3100. Through the cooperation between the protrusion 3104 and the first mounting hole 3103, on the one hand, the connection between the two can be made more stable. On the other hand, the protrusion 3104 can also play the role of central support and deformation restriction for the peripheral first core plate 3100 inside the first mounting hole 3103.

[0062] like Figure 5 As shown, the second layered energy-absorbing component 311 can specifically include a second core plate 3110 and a pair of second elastic layers 3112 stacked along the thickness direction of the second layered energy-absorbing component 311. The second core plate 3110 is a plate-like structure extending along the length direction of the beam 5. The second core plate 3110 has a certain rigidity and can play a rigid supporting role between the two connecting plates 300, preventing deformation of the column 4 and the beam 5 to a certain extent, thereby forming a highly reliable and non-breakable connection structure between the two connecting plates 300, thereby improving the stability and reliability of the wooden structure beam-column connection structure. At the same time, the second core plate 3110 also has a certain ability to absorb energy and avoid the transmission of seismic loads. Therefore, the second core plate 3110 can not only play a stabilizing supporting role for the connection between the column 4 and the beam 5, but also absorb a certain amount of energy when affected by vibration, thereby achieving energy dissipation. In order to prevent the second core plate 3110 from bending and deforming under pressure, it is necessary to set components to limit its deformation on both sides of the second core plate 3110, that is, a pair of second constraint members 3111, and each second constraint member 3111 is set to extend along the length direction of the second core plate 3110. Each second constraint member 3111 can be detachably connected to the second core plate 3110 by bolts.

[0063] The second layered energy-absorbing component 311 also includes a pair of second elastic layers 3112 arranged on both sides of the second core plate 3110, which are detachably arranged on both sides of the second core plate 3110, and each second elastic layer 3112 is also detachably provided with a second restraint member 3111 on the side away from the second core plate 3110, that is, a second elastic layer 3112 is arranged between the second core plate 3110 and the corresponding second restraint member 3111, and the second elastic layer 3112 has a strong energy absorption capacity.

[0064] It should be noted that the second core plate 3110 can be made of a memory alloy mild steel material, and the second constraint member 3111 can be made of a steel material having a harderness higher than that of the memory alloy mild steel material. The second constraint member 3111 can specifically be a plate-like structure or a strip-like structure. The second elastic layer 3112 can be made of a rubber material. When the second core plate 3110 and the second constraint member 3111 are both made of steel material and the second elastic layer 3112 is made of a rubber material, the second elastic layer 3112 can also dissipate and absorb energy through the cutting effect when the adjacent second core plate 3110 and the second constraint member 3111 are affected by a horizontal load, thereby reducing the energy transmitted by the horizontal load to the adjacent column 4 or beam 5 through the intermediate shock-absorbing portion 3, thereby reducing vibration transmission, preventing deformation, and improving the anti-collapse performance of the wooden structure beam-column connection structure. The principle of the cutting effect is the same as that of the first layered energy-absorbing component 310 and will not be repeated here.

[0065] In another embodiment of the present invention, Figure 2 、 Figure 6 and Figure 7As shown, a thin, elastic cable component 320 can be installed within the shock-absorbing space 34 as the elastic shock-absorbing assembly 32. The elastic cable component 320 can be made of a shape memory alloy (SMA). The core function of the SMA cable is to utilize its superelastic properties and shape memory effect. Under earthquake action, the SMA cable undergoes a stress-induced phase transformation from austenite to martensite during tension, absorbing seismic energy through a phase transformation hysteresis cycle. Experimental data shows that a single SMA cable can dissipate 15-25 kJ / m³ of energy within a ±35mm travel. Therefore, under seismic loads, the elastic cable component 320 will undergo some deformation. The reverse damping force generated within the elastic cable component 320 to overcome the elastic deformation can be applied to the column 4 or beam 5 to prevent disconnection between them. Even if the relative position between the column 4 and the beam 5 is offset due to the influence of horizontal load, the elastic cable component 320 has good deformation recovery ability. When the vibration ends, the SMA generates a recovery stress of up to 200-300 MPa due to the reverse phase transformation of martensite, which can control the residual displacement between the column and the beam to within 10 mm. For example, when a 30 mm lateral displacement occurs due to an earthquake, the SMA cable can recover about 90% of the deformation. The SMA can specifically be a Ni-Ti alloy wire bundle. Therefore, the elastic cable component 320 of this embodiment can restore its original unstretched shape by stress release, ensuring that the middle shock-absorbing part 3 can quickly return to its initial state after the earthquake. The wooden structure beam-column connection structure with such a structure has post-earthquake recovery ability, thereby ensuring the anti-collapse performance of the wooden structure building using it. After the prestress of the elastic cable component 320 is lost, the prestress can be re-applied by tightening the prestress adjustment knob 321 (torque wrench). Specifically, any layered energy-absorbing component can be removed to leave working space, and then the prestress can be applied to the elastic cable component 320 with a torque wrench.

[0066] It should be noted that one or more elastic cable members 320 may be provided, for example, two, three, four, or more, as long as they are evenly distributed within the shock-absorbing space 34. The elastic cable members 320 may be arranged horizontally along the extension direction of the crossbeam 5, or may be arranged at an angle within the horizontal plane, or may be arranged at an angle within the vertical plane. Each elastic cable member 320 may be fixedly connected to a corresponding connecting plate 300 at each end.

[0067] When the elastic cable components 320 are tilted, they can be arranged in pairs to ensure force balance. And when the elastic cable components 320 are tilted relative to the vertical direction, each pair of elastic cable components 320 extend crosswise relative to the vertical direction. Figure 6 The state shown in the figure should be noted that although Figure 6The two elastic cable components 320 intersect each other when viewed from the perspective shown, but are close to each other but not in contact in a three-dimensional plane to avoid interference.

[0068] The elastic cable component 320 is tilted in the shock-absorbing space 34. On the one hand, it can absorb part of the earthquake longitudinal waves. On the other hand, it can provide a reverse tension to resist deformation when the beam 5 is deformed by the bending moment of the earthquake shear wave to limit the upward or downward deflection of the beam 5.

[0069] It is understood that earthquake shear waves are S waves. When S waves are transmitted horizontally between the column 4 and the beam 5, they generate upward and downward force components at the beam-column connection. These force components cause the beam 5 to deflect in both directions in the vertical plane. When the beam 5 is deflected by the downward force component, the first elastic cable component 3201 is first stretched, and then the damping force of the first elastic cable component 3201 overcomes the elastic tension and provides an upward restoring force (T up ), resisting the falling of the beam 5; when the beam 5 is deflected by the upward component, the second elastic cable member 3202 is first stretched, and then the damping force of the elastic tension is overcome by the first elastic cable member 3201 to provide a downward restoring force for the beam 5 (T down ), which limits the upward movement of the beam 5.

[0070] That is, the crossed first elastic cable component 3201 and the second elastic cable component 3202 form a symmetrical resistance system. Regardless of the direction of the S-wave component force, either the first elastic cable component 3201 or the second elastic cable component 3202 is always in a stretched state, providing a reverse torque. The reverse torque is calculated as follows:

[0071] M=T×L×sinα.

[0072] Where M is the reverse torque, the unit is ; T is the axial tension, unit is (N); L is the length of the cable axis, unit is (m); α is the angle between the cable and the beam.

[0073] The elastic cable components 320 can be connected to the corresponding connecting plates 300 via anchors (e.g., expansion bolts or other structures with a connecting ring at one end for connection to the elastic cable component 320 and a threaded end for connection to the connecting plates 300), allowing for rapid post-earthquake disassembly. The anchors have built-in load washers for real-time monitoring of pretension decay.

[0074] In another embodiment of the present invention, Figure 8As shown, the middle shock absorbing part 3 also includes a rod-shaped shock absorbing component 33. The rod-shaped shock absorbing component 33 has a certain rigid support capacity and shock absorption performance. Therefore, by setting the rod-shaped shock absorbing component 33, the support performance and earthquake energy absorption performance of the middle shock absorbing part 3 can be further improved on the basis of the first shock absorbing component 31 and the elastic shock absorbing component 32.

[0075] Specifically, the extension direction of the rod-shaped shock-absorbing assembly 33 is parallel to the length direction of the beam 5, and the two ends of the rod-shaped shock-absorbing assembly 33 are respectively fixedly connected to a corresponding connecting plate 300. The specific connection method can be that the end of the rod-shaped shock-absorbing assembly 33 is connected to a corresponding connecting plate 300 through a spring. When the connecting plate 300 is squeezed and slightly deformed, the spring 331 connected to the end of the rod-shaped shock-absorbing assembly 33 will be compressed and deformed. When the squeezing force applied to the connecting plate 300 is too large and the spring 331 is completely compressed, the connecting plate 300 will push and squeeze the end of the rod-shaped shock-absorbing assembly 33, and the rod-shaped shock-absorbing assembly 33 begins to participate in the energy absorption process.

[0076] The rod-shaped shock absorbing component 33 can be arranged on the periphery of the first layered energy absorbing component 310, or on the periphery of the second layered energy absorbing component 311, or the rod-shaped shock absorbing component 33 can be arranged on the periphery of both the first layered energy absorbing component 310 and the second layered energy absorbing component 311, as long as the extension direction of the rod-shaped shock absorbing component 33 is parallel to the extension direction of the beam 5.

[0077] It should be noted that the periphery of the first layered energy-absorbing component 310 or the periphery of the second layered energy-absorbing component 311 refers to the two opposite sides of the layered structure. For example, the arrangement positions of a pair of first restraint members 3101 or a pair of second restraint members 3111 are located on the opposite sides of the layered structure in which they are located.

[0078] The rod-shaped shock-absorbing assembly 33 can specifically include any one or both of a hydraulic support rod 330 and a pneumatic support rod. In this embodiment, the hydraulic support rod 330 is preferably used. The two ends of the hydraulic support rod 330 are fixedly connected to a corresponding connecting plate 300. A piston, a valve and a fluid are provided inside the hydraulic support rod 330. When the internal valve is closed and the fluid does not flow, it can provide rigid support for the connection between the column 4 and the beam 5. When the internal valve is opened and the two ends or any one end thereof are subjected to the horizontal load squeezing force, the vibration absorption capacity can be adjusted by controlling the speed and pressure of the fluid flow, thereby effectively reducing the impact of the vibration on the connection structure between the column 4 and the beam 5. In other words, the rod-shaped shock-absorbing assembly 33 plays a buffering role during vibration, reducing the impact of the vibration intensity on the wooden structure building and the middle shock-absorbing part 3, avoiding excessive deformation of the middle shock-absorbing part 3, and improving the stability of the wooden structure beam-column connection structure. The two ends of the rod-shaped shock-absorbing assembly 33 can also be as follows Figure 9As shown, the spring 331 is fixed to the steel plate 332, and the steel plate 332 is connected to the connecting plate 300 by bolts. In this way, when the rod-shaped shock absorbing component 33 is damaged, the steel plate 332 can be removed from the connecting plate 300 for replacement.

[0079] When viewed along the extension direction of the crossbeam 5, and a pair of second layered energy-absorbing components 311 are respectively arranged on the upper and lower sides of the shock-absorbing space 34, and a pair of first layered energy-absorbing components 310 are respectively arranged on the left and right sides of the shock-absorbing space 34, the second constraint member 3111 may include a plurality of constraint bars arranged at intervals along the horizontal direction, and the hydraulic support rod 330 is correspondingly arranged in the gap formed by the intervals of the plurality of constraint bars. On the one hand, the structure of the combination of the rod-shaped shock-absorbing assembly 33 and the second layered energy-absorbing component 311 can improve the energy absorption effect of the overall structure, thereby enhancing the shock-absorbing effect. On the other hand, the way of assembling the plurality of constraint bars at intervals with the rod-shaped structure can also limit the rod-shaped structure through the constraint bars, thereby preventing the hydraulic support rod 330 from bending and deforming when subjected to excessive horizontal loads.

[0080] The specific working principle of the wooden structure beam-column connection structure provided by the present invention under the influence of external loads is described below.

[0081] In one of the timber structure beam-column connection structures provided by the present invention, a first shock-absorbing component 31 specifically includes a first layered energy-absorbing component 310 composed of a first core plate 3100, a pair of first restraining members 3101 and a pair of first elastic layers 3102, a second layered energy-absorbing component 311 composed of a second core plate 3110, a pair of second elastic layers 3112 and a pair of second restraining members 3111, and an elastic shock-absorbing component 320 that is arranged in pairs and tilted along the vertical direction. In the initial state where no earthquake occurs, the first core plate 3100, the first restraining member 3101, the second core plate 3110 and the second restraining member 3111 of the first layered energy-absorbing component 310 and the second layered energy-absorbing component 311 provide a rigid support force for the timber structure beam-column connection structure, maintain the rigid connection between the column 4 and the beam 5, and ensure that the timber structure beam-column connection structure is in a stable connection state. At this time, the elastic cable component 320 is in a tensioned state in the shock-absorbing space 34.

[0082] When an earthquake occurs, the seismic waves transmitted to the wooden structure beam-column connection structure are mainly seismic shear waves, and when the seismic shear waves are transmitted to the first shock-absorbing component 31 and the elastic shock-absorbing component 32 through the connecting plate 300, the first core plate 3100 and the second core plate 3110 in the first layered energy-absorbing component 310 of the first shock-absorbing component 31 absorb part of the transmitted energy and convert the mechanical energy into internal energy to achieve energy dissipation.

[0083] As the vibration intensity continues to increase, a cutting effect will occur between the first elastic layer 3102 and the first core plate 3100 and the first restraint member 3101, and between the second elastic layer 3112 and the second core plate 3110 and the second restraint member 3111, thereby dissipating the vibration energy.

[0084] When the vibration intensity increases further, the two connecting plates 300 may have a tendency to break and separate. At this time, the elastic cable component 320 will be stretched and elastically deformed. During the elastic deformation process, the elastic cable component 320 can absorb part of the vibration energy (including the energy of the earthquake shear wave and part of the energy of the earthquake longitudinal wave), and convert the mechanical energy into elastic potential energy. At the same time, the damping force of the elastic cable component 320 to overcome the elastic deformation will also limit the disconnection between the two connecting plates 300.

[0085] After the vibration ends, if the crossbeam 5 deflects upward or downward relative to the column 4, the deformation recovery force of the elastic cable component 320 can be used to pull the deflected crossbeam 5 back to its original state.

[0086] In summary, the wooden structure beam-column connection structure provided by the present invention integrates the functions of reliable connection, absorption of vibration energy, prevention of beam-column stress deformation, and post-earthquake recovery. Its shock absorption effect is better and can meet the higher reliability, safety, stability and anti-collapse performance requirements of wooden structure buildings.

[0087] In another wooden structure beam-column connection structure disclosed in the present invention, taking the middle shock-absorbing part 3 of the wooden structure beam-column connection structure as an example, in addition to including the above-mentioned first shock-absorbing component 31 and elastic shock-absorbing component 32, it also includes a rod-shaped shock-absorbing component 33 (the rod-shaped shock-absorbing component 33 includes a hydraulic support rod 330). The shock-absorbing effect of this structure is different from that of the above-mentioned structure in that: in the initial state where no earthquake occurs, the valve in the hydraulic support rod 330 is closed and the liquid does not flow, so that the hydraulic support rod 330 also provides a rigid support force for the wooden structure beam-column connection structure, maintains the rigid connection between the column 4 and the beam 5, and ensures that the connection structure is in a stable connection state.

[0088] When an earthquake occurs, the energy absorption process of the first shock absorbing assembly 31 and the elastic shock absorbing assembly 32 is the same as that of the above structure.

[0089] As the vibration intensity continues to increase, the extrusion force or tensile force applied to the hydraulic support rod 330 may not have reached the pressure value for opening the hydraulic support rod 330. The hydraulic support rod 330 is in a locked state. The hydraulic support rod 330 acts as a supporting component between the two connecting plates 300 to prevent large deformation of the wooden structure beam-column connection structure.

[0090] When the vibration intensity increases further, one end of the hydraulic support rod 330 will also be affected by compression or tension. When the extrusion force or tension force applied to the hydraulic support rod 330 by the earthquake reaches the pressure value for opening the hydraulic support rod 330, the fluid begins to flow in the hydraulic support rod 330, thereby absorbing the vibration energy.

[0091] After the vibration ends, the hydraulic support rod 330 can also be reset by changing its axial length after the vibration.

[0092] To sum up, when the middle shock-absorbing part 3 of the wooden structure beam-column connection structure includes a rod-shaped shock-absorbing component 33 in addition to the first shock-absorbing component 31 and the elastic shock-absorbing component 32, a three-level shock-absorbing structure is formed, and such a structure integrates the functions of reliable connection, absorption of vibration energy, prevention of stress deformation of beams and columns, and post-earthquake recovery. Its shock-absorbing effect is better and can meet the higher reliability, safety, stability and anti-collapse performance requirements of wooden structure buildings.

[0093] In another embodiment of the present invention, Figure 10-13 As shown, the column connecting portion 1 includes a column slot 10 formed on the top surface of the column 4. The column slot 10 is formed vertically on the top surface of the column 4. Since the crossbeam 5 is usually connected to the side wall of the column 4, the column slot 10 is configured to pass through the corresponding side wall of the column 4. One end of the column connector 11 is inserted into the column slot 10, and the other end is fixedly connected to a corresponding connecting plate 300. Inserting the column connector 11 into the column slot 10 can not only expand the contact area between the column 4 and the crossbeam 5, but also utilize the blocking effect of the side wall of the column slot 10 on the column connector 11 to prevent deformation or dislocation of the column connector 11 due to earthquakes. The column connector 11 may include a column plug-in plate 110 inserted into the column slot 10 and a column T-shaped plate 111 fixedly connected to the end of the column plug-in plate 110. The column T-shaped plate 111 is composed of two mutually perpendicular plate structures, and one of the plate structures is connected to the middle of the other plate structure. The end of the T-shaped tail of the column T-shaped plate 111 can be extended into the column slot 10, and is fixedly connected to the column plug-in plate 110 in the column slot 10 through the column connecting bolt 112. The side of the T-shaped top of the column T-shaped plate 111 away from the column 4 is used to be opposite to and fixedly connected to a corresponding connecting plate 300.

[0094] By adopting the above solution, the connection between the column 4 and the connecting plate 300 can be made stable and reliable by inserting the column connector 11 into the column slot 10 for plugging. The side wall of the column slot 10 can prevent the column plug-in plate 110 of the column connector 11 and the T-shaped tail of the column T-shaped plate 111 from being deformed.

[0095] It should be noted that the column slot 10 can pass through one side wall of the column 4, or two side walls, three side walls, or all four side walls of the column 4, and the shape and number of the corresponding column connectors 11 can be adjusted according to the actual situation of the column slot 10. For example, when all four side walls of the column 4 need to be connected to the crossbeam 5, as shown in FIG. Figure 10-13 As shown, the column slot 10 is cross-shaped and passes through the four side walls of the column 4. The corresponding column plug-in board 110 is also cross-shaped. The column plug-in board 110 can be composed of two mutually cross-connected plate structures ( Figure 10 The two plate structures are not connected. Figure 11 The two plate-like structures are cross-connected. ) A column T-shaped plate 111 is connected to each end of the cross-shaped column plug-in plate 110.

[0096] See further Figure 12-13 The crossbeam connecting portion 2 includes a crossbeam slot 20 provided on the end face of the crossbeam 5 along the extension direction of the crossbeam 5. The crossbeam slot 20 extends vertically through the end face of the crossbeam 5. The two ends of the crossbeam connecting member 21 are respectively fixedly connected to the crossbeam slot 20 and the corresponding other connecting plate 300. The crossbeam connecting member 21 may include a crossbeam T-shaped plate 210. The crossbeam T-shaped plate 210 is composed of two mutually perpendicular plate-like structures, one of which is connected to the middle of the other plate-like structure. The end of the crossbeam T-shaped plate 210 where the T-shaped tail is located can be extended into the crossbeam slot 20 and fixedly connected in the crossbeam slot 20 by a crossbeam connecting bolt 211. The T-shaped top of the crossbeam T-shaped plate 210 is used to face and be fixedly connected to the corresponding one of the connecting plates 300 on the side away from the crossbeam 5.

[0097] By adopting the above solution, the connection between the beam 5 and the connecting plate 300 can be made stable and reliable by inserting the beam connector 21 into the beam slot 20 for plugging. The side wall of the beam slot 20 can prevent the T-shaped tail of the column T-shaped plate 111 from deformation.
