Description

Technical Field

[0001] This invention relates to the field of timber structure building technology, and in particular to a timber beam-column connection structure. Background Technology

[0002] Beam-column connections are a crucial component of building structures. Their function is to securely connect beams and columns, transfer loads (such as vertical forces, horizontal forces, bending moments, and shear forces), and ensure the overall stability and safety of the structure.

[0003] Especially for wooden beams and columns, the compressive and tensile strength of wooden beams and columns is much lower than that of reinforced concrete beams and columns. Wooden beams and columns themselves cannot bear large loads. Under the influence of severe environmental factors such as earthquakes and strong winds, the connection structure of wooden beams and columns is very prone to damage, breakage, bending and deformation, which affects the safety and stability of the overall building structure.

[0004] Besides the inherently low strength of wood, making it difficult to withstand excessive loads, the connection between the columns and beams inevitably involves gaps between the two opposing surfaces. Furthermore, this connection point is a point of concentrated stress on the beams and columns, making them prone to separation under dynamic loads such as earthquakes and strong winds. Therefore, the beam-column connection structure in timber structures is a "weak link" in timber building design. Moreover, the transmission of load vibrations between beams and columns can cause widespread damage to the overall building structure. Strengthening the reliability of the connection between columns and beams and absorbing and dispersing external vibrations are essential to ensuring the stability of timber buildings.

[0005] Therefore, the design of timber beam-column connection structures needs to comprehensively consider its connection stability and vibration reduction performance from multiple aspects, such as achieving reliable connection, absorbing vibration energy, preventing beam and column deformation under stress, and post-earthquake recovery. Currently, there is no timber beam-column connection structure that integrates the above functions. Existing timber beam-column connection structures suffer from poor connection reliability and poor vibration reduction effect. As people's requirements for the quality of timber structures increase, current timber beam-column connection structures cannot meet the higher requirements for reliability, safety, stability, and collapse resistance of timber structures. Summary of the Invention

[0006] The purpose of this invention is to solve the problem that existing wooden beam-column connection structures lack integrated reliable connection, vibration energy absorption, beam and column deformation prevention, and post-earthquake recovery functions. Existing wooden beam-column connection structures suffer from poor connection reliability and poor vibration reduction effect. As people's requirements for the quality of wooden buildings are increasing, current wooden beam-column connection structures cannot meet the higher requirements for reliability, safety, stability, and collapse resistance of wooden buildings.

[0007] To address the aforementioned technical problems, embodiments of the present invention provide a timber beam-column connection structure, including a column connection portion, a beam connection portion, and an intermediate damping portion connecting the column connection portion and the beam connection portion. The column connection portion is fixed to the top of the column, and the beam connection portion is fixed to the end of the beam; the intermediate damping portion includes a mounting base and a first damping component and an elastic damping component fixedly connected to the mounting base. The mounting base includes a pair of connecting plates spaced apart from each other along the extension direction of the beam, the pair of connecting plates being detachably fixedly connected to the corresponding ends of the column connection portion and the beam connection portion; the first damping component is circumferentially disposed between the pair of connecting plates, with its two ends fixedly connected to a corresponding connecting plate, forming a damping space between the first damping component and the pair of connecting plates; the elastic damping component is disposed within the damping space, and its two ends are fixedly connected to a corresponding connecting plate.

[0008] The intermediate damping section, located between the column connection and the beam connection, is the core structure responsible for vibration damping. When subjected to seismic waves, this section absorbs seismic energy, dissipating it and reducing its transmission between the column and beam. It also provides a reverse damping force to prevent breakage of the column-beam connection, enhancing structural stability. Furthermore, it provides a reverse restoring tensile force after slight deflection between the column and beam, restoring the structure to its initial state. Specifically, the intermediate damping section comprises multiple components, such as a mounting base, a first damping component, and an elastic damping component. The two connecting plates of the mounting base serve as the mounting foundation for the other damping components. The first damping component absorbs seismic shear waves, thereby reducing the energy transfer of seismic waves. By circumferentially surrounding a pair of connecting plates, the first damping component can absorb seismic energy in multiple directions around the circumference of the connecting plates. The damping space formed by the first damping component and the connecting plates also provides installation space for the elastic damping component, resulting in a reasonable and compact spatial layout. When the beam and column are prone to fracture due to seismic waves, the elastic damping component prevents fracture by overcoming the damping force of elastic deformation. It can also provide a reverse restoring tensile force after slight misalignment deformation between the column and beam, restoring the structure to its initial state. Therefore, compared with existing technologies, the timber beam-column connection structure of this scheme integrates functions such as absorbing vibration energy, preventing beam and column deformation under stress, and post-earthquake recovery. Its damping effect is superior, meeting the higher reliability, safety, stability, and collapse resistance requirements of timber structures.

[0009] According to another specific embodiment of the present invention, the timber beam-column connection structure disclosed in the present invention includes an elastic damping component comprising a pair of elastic cable components disposed in the damping space; each elastic cable component is fixedly connected at both ends to a corresponding connecting plate and extends obliquely relative to the vertical direction; and each pair of elastic cable components extends intersectingly with each other relative to the vertical direction.

[0010] By employing the above technical solution, the inclined arrangement of the elastic cable components within the damping space can absorb a portion of the seismic longitudinal waves. Furthermore, it can provide a counter-tensile force to resist deformation when the beam is subjected to bending moment deformation, thus limiting the beam's upward or downward deflection. Arranging the elastic cable components in pairs and crosswise ensures that the overall structure maintains a stress balance.

[0011] The beneficial effects of this invention are:

[0012] The column connection and beam connection are the connection foundations of the timber beam-column connection structure provided by this invention. The intermediate damping section is the core structure that plays a damping role. In the intermediate damping section, the two connecting plates of the mounting base serve as the mounting foundation for other damping components. The first damping component can absorb seismic shear waves, thereby reducing the energy transmission of seismic waves. By circumferentially surrounding the pair of connecting plates, the first damping component can absorb seismic energy in multiple directions along the circumference of the pair of connecting plates. The damping space formed by the first damping component and the pair of connecting plates also provides installation space for the elastic damping component, resulting in a reasonable and compact spatial layout. When there is a tendency for fracture between the beam and the column due to the influence of seismic waves, the elastic damping component prevents the two from fracture by overcoming the damping force of elastic deformation. It can also provide a reverse restoring tensile force after a slight deflection between the column and the beam, allowing the structure to return to its initial state. Therefore, compared with existing technologies, the timber beam-column connection structure of this solution can integrate functions such as absorbing vibration energy, preventing beam and column deformation under stress, and post-earthquake recovery. Its vibration reduction effect is better and can meet the higher reliability, safety, stability and collapse resistance requirements of timber structure buildings. Attached Figure Description

[0035] The beam-column connection structure in timber structure is a "weak link" in timber structure building design; and the transmission of load vibration between beams and columns can 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 timber structure buildings.

[0036] Common failure modes in timber beam-column joint structures include: When the shear resistance of the timber beam-column joint is insufficient, diagonal cracks will appear between the beam and column joint surfaces under shear force. As the load increases, the cracks continue to develop, eventually leading to fracture at the beam-column joint and loss of load-bearing capacity. This failure mode is usually brittle and poses a significant threat to the safety of the building structure. If the bending resistance of the beam ends is insufficient, bending cracks will appear at the beam ends at the joint. As the cracks develop, the beam ends will yield, and the beam will lose its bending resistance. Although this failure mode has a certain degree of ductility, it will still affect the normal use and safety of the joint structure. Column ends may also fail at the joints due to excessive vertical loads, leading to a decrease in the load-bearing capacity of the column and affecting the stability of the entire building structure.

[0037] Therefore, when a timber structure is subjected to excessive loads, and the load on the beams or columns is transferred to the timber beam-column connection structure, it is necessary to absorb and dissipate some of the vibrational energy at this point to minimize the transmission of destructive energy. Simultaneously, the timber beam-column connection structure must possess strong connection reliability to constrain the relative displacement of the beams and columns, maintain the geometric relationship between components, and ensure the overall structural stiffness. 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 structures must consider the stress characteristics of the timber beam-column connection structure under earthquakes or strong winds, such as repeated shear and bending moment effects. Through proper design, the timber beam-column connection structure 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] Currently, there is no integrated timber beam-column connection structure that combines reliable connection, vibration energy absorption, prevention of beam and column deformation under stress, and post-earthquake recovery functions. Existing timber beam-column connection structures suffer from poor reliability and poor vibration reduction. As people's requirements for the quality of timber-framed buildings continue to increase, current timber beam-column connection structures are unable to meet the higher requirements for reliability, safety, stability, and collapse resistance of timber-framed buildings.

[0040] To address the aforementioned issues, this invention provides a timber beam-column connection structure that integrates functions such as absorbing vibration energy, preventing beam and column deformation under stress, and post-earthquake recovery. It offers superior vibration damping performance and can meet the higher requirements for reliability, safety, stability, and collapse resistance in timber-framed buildings.

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

[0042] Example 1

[0043] Embodiment 1 of the present invention provides a timber 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 foundation of the wooden 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 the beam 5 near the column 4. The opposing surfaces of the column connection part 1 and the beam connection part 2 can be connected by 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, it should be noted that the external vibration loads on the timber beam-column connection structure mainly include earthquakes and strong winds. Earthquake loads mainly include horizontal and longitudinal loads. The load of strong winds on timber structures is mainly lateral load. Furthermore, the destructive impact and hazards of earthquake loads are stronger than those of strong winds. In earthquake scenarios, horizontal loads (mainly seismic shear waves) are more damaging to timber structures than longitudinal loads (mainly seismic longitudinal waves). Therefore, in this embodiment 1, we will take the scenario of a timber structure being affected by earthquake loads as an example to introduce the various damping components of the timber beam-column connection structure.

[0045] The intermediate damping section 3, located between the column connection 1 and the beam connection 2, is the core structure that plays a role in damping vibration. Figure 1 and Figure 2 As shown, the intermediate damping section 3 includes a first damping component 31 and an elastic damping component 32. The first damping component 31 is a structural component with shock absorption performance. For example, it can be a connecting web with an arc-shaped energy-dissipating cover plate, or it can be an energy-absorbing layer structure composed of multiple plate-like structures. When a horizontal load is transmitted to the intermediate damping section 3, it can dissipate seismic energy here, reducing the transmission of seismic energy between the column 4 and the beam 5. In addition, the first damping component 31 should also have a certain supporting performance, providing reliable support between the column 4 and the beam 5, increasing the connection stability between the two, and preventing the beam and column from being deformed by compression. The elastic damping component 32 is a structural component with a certain elastic deformation capacity. The components can be, for example, springs or stretchable rope structures. When the column 4 and beam 5 are subjected to seismic loads and tend to undergo shear fracture or bending moment deformation, the elastic potential energy of the elastic damping component 32 can absorb some of the energy. It can also use its restoring force to overcome elastic deformation to provide a reverse damping force between the column 4 and beam 5 to prevent them from breaking or deflecting relative to each other, thereby limiting the deformation of the beam and column under compression and enhancing the stability of the wooden beam-column connection structure. The deformation restoring force of the elastic damping component 32 can also provide a reverse restoring tensile force after slight deflection or cracking occurs between the column 4 and beam 5, so that the wooden beam-column connection structure can return to its initial state before being affected by the earthquake.

[0046] In summary, the intermediate damping part 3, which includes the first damping component 31 and the elastic damping component 32, integrates reliable connection, absorption of vibration energy, prevention of beam and column deformation under stress, and post-earthquake recovery functions, and can meet the higher reliability, safety, stability and anti-collapse performance requirements of wooden structures.

[0047] Furthermore, such as Figure 1 and Figure 2As shown, the intermediate damping section 3 also includes a mounting base 30. The mounting base 30 includes a pair of connecting plates 300 spaced apart from each other along the extension direction of the crossbeam 5. This pair of connecting plates 300 serves as the mounting base for other damping components. The uprights 4 and the crossbeam 5 can be connected to the opposite sides of the two connecting plates 300, respectively. Other damping components (see, for example, [reference needed]) can be connected to the opposite sides of the two connecting plates 300. Figure 1 The first shock absorber component 31 and Figure 2 The elastic damping component 32 is used in the middle. Furthermore, the pair of connecting plates 300 are detachably fixedly connected to the corresponding ends of the column connecting part 1 and the beam connecting part 2. The middle damping part 3 is small in size. When the middle damping part 3 is severely damaged, the detachable connection makes it easy to replace the middle damping part 3 between the column 4 and the beam 5. Specifically, threaded holes can be opened at the ends of the connecting plates 300 and the corresponding connecting parts, and detachable connection can be achieved by bolts; alternatively, plug-in parts protruding towards the column 4 and the beam 5 can be provided on the opposite surface of the connecting plates 300, and slots can be opened at the corresponding ends of the column 4 and the beam 5, and detachable connection can be achieved 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 connection end face of the column 4 and the beam 5. For example, when the connection end face of the column 4 and the beam 5 is rectangular, the corresponding connecting plate 300 can be set as rectangular. When the connection end face of the column 4 and the beam 5 is circular, the corresponding connecting plate 300 can be set as a circular plate structure. Of course, it can also be set as other irregular shapes.

[0049] The first damping component 31 is disposed between a pair of connecting plates 300, with its two ends fixedly connected to a corresponding connecting plate 300. When seismic waves are transmitted to the first damping component 31, they can be absorbed by the first damping component 31 using its shock absorption performance, thus dispersing energy and effectively reducing the transmission of seismic waves (especially seismic shear waves), thereby preventing serious damage to the beam 5 or column 4. Furthermore, the first damping component 31 is disposed circumferentially between the pair of connecting plates 300; for example, it can be disposed circumferentially around the edge of each connecting plate 300. Figure 1 As shown, the first damping component 31 is positioned above, below, in front of, and behind the crossbeam 5 in four directions, along the width direction of the space between the two connecting plates 300, so that a damping space 34 is formed between the first damping component 31 and the pair of connecting plates 300. The damping space 34 is as follows: Figure 2As shown, this arrangement allows the first damping component 31 to absorb seismic energy from multiple directions (i.e., the circumferential direction of the connecting plate 300), and the large energy absorption area results in better energy absorption. In addition, the damping space 34 formed by the first damping component 31 and the pair of connecting plates 300 can also provide installation space for the elastic damping component 32, making the spatial layout of the intermediate damping part 3 reasonable and compact.

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

[0051] like Figure 2 As shown, the elastic damping component 32 is disposed within the damping space 34. The elastic damping component 32 has elastic tensile deformation capability and damping force to overcome elastic tension. Therefore, the two ends of the elastic damping component 32 are respectively fixedly connected to a corresponding connecting plate 300. When the column 4 and the beam 5 are affected by seismic load and tend to undergo shear fracture or bending moment deformation, the elastic potential energy of the elastic damping component 32 can absorb part of the energy. It can also use its restoring force to overcome elastic deformation to provide a reverse damping force for the connection between the column 4 and the beam 5 to prevent them from breaking or deflecting relative to each other, thereby limiting the deformation of the beam and column under compression and enhancing the stability of the wooden beam-column connection structure. The deformation restoring force of the elastic damping component 32 can also provide a reverse restoring tension after slight deflection or cracking occurs between the column 4 and the beam 5, so that the wooden beam-column connection structure returns to its initial state unaffected by the earthquake.

[0052] It should be noted that the elastic damping component 32 can be a strip structure, column structure, rod structure or plate structure. The elastic damping component 32 can be horizontally extended in the damping space 34 or inclined relative to the vertical direction. When the elastic damping component 32 is horizontally installed in the damping space 34, the deformation restoring force of the elastic damping component 32 is a horizontal force. When the elastic damping component 32 is inclined relative to the vertical direction in the damping space 34, the deformation restoring force of the elastic damping component 32 is an inclined force relative to the vertical direction.

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

[0054] In one specific embodiment of the present invention, such as Figure 1 and Figure 2As shown, when each connecting plate 300 is configured as a rectangular plate structure, all four sides of the rectangular plate structure can be used to connect the corresponding first damping component 31. Furthermore, the first damping component 31 may 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, resulting in a more uniform spatial distribution and uniform damping and energy absorption during vibration dissipation. Both ends of each first layered energy-absorbing component 310 are fixedly connected to the inner wall of a corresponding connecting plate 300. Viewed along the extension direction of the beam 5, the pair of first layered energy-absorbing components 310 can be respectively positioned on the upper and lower sides of the damping space 34, or respectively on the left and right sides of the damping space 34.

[0055] like Figure 1 As shown, the first damping component 31 may further include a pair of second layered energy-absorbing components 311 spaced apart from each other (due to...). Figure 1 The reasons for the obstruction of the viewpoint in the middle, Figure 1 Only one of the second-layered energy-absorbing components 311 is shown in the diagram. Setting the second-layered energy-absorbing component 311 as a layered structure allows it to be arranged parallel to the edge of the connecting plate 300, resulting in a more uniform spatial distribution. This ensures uniform energy absorption and vibration dissipation during shock absorption, and also provides stable support around the periphery of the shock-absorbing space 34. Each second-layered energy-absorbing component 311 can be fixedly connected at both ends to the inner wall of a corresponding connecting plate 300. Viewed along the extension direction of the beam 5, a pair of second-layered energy-absorbing components 311 can be positioned on the upper and lower sides of the shock-absorbing space 34, or on the left and right sides of the shock-absorbing 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 damping space 34, with each second layered energy-absorbing component 311 extending 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 damping space 34, with each first layered energy-absorbing component 310 extending 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 the first layered energy-absorbing components 310 can be provided, for example in... Figure 1 In the structure shown, three pairs of first-layer energy-absorbing components 310 are arranged on the left and right sides of the damping space 34, with the first-layer energy-absorbing components 310 on each side arranged sequentially in the vertical direction. Of course, the first-layer energy-absorbing components 310 can also be set to two pairs, four pairs, etc. The number of second-layer energy-absorbing components 311 can also be increased according to the damping requirements, and set to two pairs, three pairs, four pairs, etc.

[0057] Furthermore, such as Figure 3 and Figure 4As shown, the first layered energy-absorbing component 310 may specifically include a first core plate 3100 and a pair of first constraint members 3101 stacked along the thickness direction of the first layered energy-absorbing component 310. The first core plate 3100 has a plate-like structure extending along the length direction of the beam 5. The first core plate 3100 has a certain rigidity and can provide rigid support between the two connecting plates 300, preventing deformation of the column 4 and beam 5 to a certain extent. This results in a highly reliable and less prone-to-break connection structure between the two connecting plates 300, improving the stability and reliability of the timber beam-column connection structure. Simultaneously, the first core plate 3100 also has a certain ability to absorb energy and prevent the transmission of seismic loads. Therefore, the first core plate 3100 can both provide stable support for the connection between the column 4 and beam 5 and absorb a certain amount of energy when subjected to vibration, thus achieving energy dissipation. To prevent the first core plate 3100 from bending under pressure, it is necessary to provide components that limit its deformation on both sides of the first core plate 3100, namely a pair of first constraint members 3101. Each first constraint member 3101 is configured to extend along the length direction of the first core plate 3100. Each first constraint member 3101 and the first core plate 3100 can be detachably connected by bolts 3106 and second mounting holes 3105.

[0058] It should be noted that the first core plate 3100 can be made of shape memory alloy mild steel, and the first constraint member 3101 can be made of steel with a hardness higher than that of shape memory alloy mild steel. Specifically, 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 the largest possible area to limit its deformation, the first constraint member 3101 is preferably configured as follows: Figure 3 and Figure 4 The plate-like structure shown.

[0059] Furthermore, see again Figure 3 and Figure 4 The first layered energy-absorbing component 310 may also include a pair of first elastic layers 3102 disposed on both sides of the first core plate 3100, that is, a first elastic layer 3102 is disposed between the first core plate 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 plate 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 damping part 3, thereby reducing vibration transmission, preventing deformation, and improving the collapse resistance of the wooden beam-column connection structure.

[0060] It should be noted that the cutting effect refers to the relative displacement that occurs between the steel first core plate 3100, the first restraint member 3101, and the first elastic layer 3102 when a horizontal load (such as a seismic shear wave) is applied. The first elastic layer 3102 is obliquely stretched or compressed, while the rigidity of the steel plate (first restraint member 3101 and first core plate 3100) restricts the free deformation of the first elastic layer 3102, forcing high shear stress to be generated inside the first elastic layer 3102. The steel plate and the first elastic layer 3102 repeatedly cut each other, and the first elastic layer 3102 generates heat through friction during repeated shear deformation, converting mechanical energy into heat energy, thereby achieving energy dissipation. The first elastic layer 3102 can be made of rubber material.

[0061] The steel plate and the first elastic layer 3102 can be bonded together to ensure coordinated deformation and prevent interlayer slippage failure. For example... Figure 4 As shown, a first mounting hole 3103 can also be formed on the first core plate 3100, extending along the thickness direction of the first layered energy-absorbing component 310. A protrusion 3104 adapted to the first mounting hole 3103 is provided 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, and on the other hand, the protrusion 3104 can also play the role of central support and limiting deformation of the outer periphery of the first core plate 3100 within the first mounting hole 3103.

[0062] like Figure 5 As shown, the second layered energy-absorbing component 311 may 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 has a plate-like structure extending along the length direction of the beam 5. The second core plate 3110 has a certain rigidity and can provide rigid support between the two connecting plates 300, preventing deformation of the column 4 and beam 5 to a certain extent. This results in a highly reliable and less prone-to-break connection structure between the two connecting plates 300, improving the stability and reliability of the timber beam-column connection structure. Simultaneously, the second core plate 3110 also has a certain ability to absorb energy and prevent the transmission of seismic loads. Therefore, the second core plate 3110 can both provide stable support for the connection between the column 4 and beam 5 and absorb a certain amount of energy when subjected to vibration, thus achieving energy dissipation. To prevent the second core plate 3110 from bending under pressure, it is necessary to provide components that limit its deformation on both sides of the second core plate 3110, namely a pair of second constraint members 3111. Each second constraint member 3111 is configured to extend along the length direction of the second core plate 3110, and 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 disposed on both sides of the second core plate 3110. These layers are detachably disposed on both sides of the second core plate 3110, and each second elastic layer 3112 is detachably disposed on the side away from the second core plate 3110 with a second constraint member 3111. That is, a second elastic layer 3112 is disposed between the second core plate 3110 and the corresponding second constraint member 3111. 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 shape memory alloy mild steel, and the second restraint member 3111 can be made of steel with a hardness higher than that of shape memory alloy mild steel. Specifically, the second restraint member 3111 can be a plate-like structure or a strip-like structure. The second elastic layer 3112 can be made of rubber. When both the second core plate 3110 and the second restraint member 3111 are made of steel, and the second elastic layer 3112 is made of rubber, the second elastic layer 3112 can also dissipate and absorb energy through a cutting effect when the adjacent second core plate 3110 and second restraint member 3111 are subjected to horizontal loads. This reduces the energy transmitted by the horizontal load to the adjacent columns 4 or beams 5 through the intermediate damping part 3, thereby reducing vibration transmission, preventing deformation, and improving the collapse resistance of the timber 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 elaborated here.

[0065] In another specific embodiment of the present invention, such as Figure 2 , Figure 6 and Figure 7As shown, a thin strip of elastic cable component 320 can be installed within the damping space 34 as an elastic damping component 32. The elastic cable component 320 can be made of shape memory alloy (SMA). The core function of the SMA cable is to utilize its superelastic properties and shape memory effect. Under seismic loading, the SMA cable undergoes a stress-induced phase transformation from austenite to martensite during stretching, absorbing seismic energy through phase transformation hysteresis loop. Experimental data shows that a single SMA cable can dissipate 15-25 kJ / m³ of energy within a ±35mm stroke. Therefore, under seismic load, the elastic cable component 320 will deform to a certain extent. After being stretched, the reverse damping force generated inside the elastic cable component 320 to overcome the elastic deformation can be applied to the column 4 or the beam 5 to prevent them from breaking apart. Even if the relative positions of the column 4 and the beam 5 shift due to horizontal loads, the elastic cable component 320 has excellent deformation recovery capabilities. After the vibration ends, the SMA generates a recovery stress of up to 200-300 MPa due to the inverse martensitic transformation, which can control the residual displacement between the column and the beam 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 through stress release, ensuring that the intermediate damping part 3 can quickly return to its initial state after an earthquake. The timber beam-column connection structure with such a structure has post-earthquake recovery capabilities, thereby ensuring the collapse resistance of the timber structure building using it. After the prestress of the elastic cable component 320 is lost, the prestress can be reapplied by tightening the prestress adjustment knob 321 (torque wrench). Specifically, this can be done by removing any layered energy-absorbing component to create working space, and then applying prestress to the elastic cable component 320 with a torque wrench.

[0066] It should be noted that there can be one or more elastic cable components 320, such as two, three, four or more, as long as they are evenly distributed within the damping space 34. The elastic cable components 320 can be installed horizontally along the extension direction of the crossbeam 5, inclined in the horizontal plane, or inclined in the vertical plane. Each elastic cable component 320 is fixedly connected at both ends to a corresponding connecting plate 300.

[0067] When the elastic cable components 320 are inclined, they can be arranged in pairs to ensure force balance. Furthermore, when the elastic cable components 320 extend inclined relative to the vertical direction, each pair of elastic cable components 320 extends intersecting each other relative to the vertical direction; see details below. Figure 6 The state shown should be noted that, although from Figure 6When viewed from the perspective shown, the two elastic cable components 320 intersect each other, but in the three-dimensional plane, they are close to each other but do not touch each other to avoid interference.

[0068] The elastic cable component 320 is tilted within the damping space 34. On the one hand, it can absorb part of the longitudinal seismic wave. On the other hand, it can provide a reverse tensile force to resist deformation when the crossbeam 5 is subjected to bending moment deformation by the transverse seismic wave, so as to limit the upward or downward deflection of the crossbeam 5.

[0069] It is understandable that the seismic shear wave is an S-wave. When the S-wave propagates horizontally between the column 4 and the beam 5, it generates upward and downward components at the beam-column connection. These components cause the beam 5 to deflect bidirectionally in the vertical plane. When the beam 5 deflects under the downward component force, the first elastic cable component 3201 is first stretched, and then, through the damping force of the first elastic cable component 3201 overcoming the elastic tension, it provides an upward restoring force (T) to the beam 5. up The second elastic cable component 3202 is first stretched, and then provides a downward restoring force (T) to the crossbeam 5 to resist its downward fall. When the crossbeam 5 is deflected by an upward component force, the second elastic cable component 3202 is first stretched, and then provides a downward restoring force (T) to the crossbeam 5 by overcoming the damping force of the elastic tension through the first elastic cable component 3201. down ), restricting the upward movement of crossbeam 5.

[0070] In other words, the intersecting first elastic cable component 3201 and second elastic cable component 3202 form a symmetrical resistance system. Regardless of the direction of the S-wave force component, either the first elastic cable component 3201 or the second elastic cable component 3202 is always in a tensile state, providing a reverse torque; the formula for calculating the reverse torque is:

[0071] M = T × L × sinα.

[0072] In the formula, M is the reverse torque, and the unit is _____. T is the axial tension, in N; L is the length of the cable axis, in m; α is the angle between the cable and the beam.

[0073] The elastic cable component 320 can be connected to the corresponding connecting plate 300 via an anchor (e.g., an expansion bolt or other structure with a connecting ring at one end for connection to the elastic cable component 320 and threads at the other end for connection to the connecting plate 300), allowing for quick disassembly after an earthquake. The anchor has a built-in force-measuring washer for real-time monitoring of pretension decay.

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

[0075] Specifically, the extension direction of the rod-shaped damping component 33 is parallel to the length direction of the crossbeam 5, and both ends of the rod-shaped damping component 33 are fixedly connected to a corresponding connecting plate 300. The specific connection method can be that the end of the rod-shaped damping component 33 is connected to the corresponding connecting plate 300 through a spring. When the connecting plate 300 is compressed and slightly deformed, the spring 331 connected to the end of the rod-shaped damping component 33 will be compressed and deformed. When the compressive force on the connecting plate 300 is too large and the spring 331 is completely compressed, the connecting plate 300 will push and compress the end of the rod-shaped damping component 33, and the rod-shaped damping component 33 will begin to participate in the energy absorption process.

[0076] The rod-shaped damping component 33 can be disposed on the outer periphery of the first layered energy-absorbing component 310, or on the outer periphery of the second layered energy-absorbing component 311, or the rod-shaped damping component 33 can be disposed on the outer 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 damping component 33 is parallel to the extension direction of the crossbeam 5.

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

[0078] The rod-shaped damping component 33 can specifically include any one or both of a hydraulic support rod 330 and a pneumatic support rod. In this embodiment, a hydraulic support rod 330 is preferred. Both ends of the hydraulic support rod 330 are fixedly connected to a corresponding connecting plate 300. The hydraulic support rod 330 is internally equipped with a piston, a valve, and fluid. 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 open, and either or both ends are subjected to horizontal load pressure, the ability to absorb vibration can be adjusted by controlling the speed and pressure of the fluid flow, thereby effectively mitigating the impact of vibration on the connection structure between the column 4 and the beam 5. In other words, the rod-shaped damping component 33 acts as a buffer during vibration, reducing the impact of vibration intensity on the wooden structure and the intermediate damping part 3, preventing excessive deformation of the intermediate damping part 3, and improving the stability of the wooden beam-column connection structure. The two ends of the rod-shaped damping component 33 can also be... Figure 9As shown, the steel plate 332 is fixed to the spring 331, and the steel plate 332 is then connected to the connecting plate 300 by bolts. In this way, the steel plate 332 can be removed from the connecting plate 300 and replaced after the rod-shaped shock absorber 33 is damaged.

[0079] When viewed along the extension direction of the crossbeam 5, and with a pair of second layered energy-absorbing components 311 respectively disposed on the upper and lower sides of the damping space 34, and a pair of first layered energy-absorbing components 310 respectively disposed on the left and right sides of the damping space 34, the second constraint member 3111 may include multiple constraint strips spaced apart in the horizontal direction, and the hydraulic support rod 330 is correspondingly disposed in the gaps formed by the multiple constraint strips. The structure of the rod-shaped damping component 33 combined with the second layered energy-absorbing component 311 can improve the energy absorption of the overall structure, thereby improving the damping effect. On the other hand, the way multiple constraint strips are spaced apart from the rod-shaped structure can also limit the rod-shaped structure through the constraint strips, preventing the hydraulic support rod 330 from bending and deforming when subjected to excessive horizontal load.

[0080] The working principle of the timber beam-column connection structure provided by this invention under the influence of external loads will be explained below.

[0081] In one of the timber beam-column connection structures provided by the present invention, the first damping component 31 specifically includes a first layered energy-absorbing component 310 composed of a first core plate 3100, a pair of first constraint 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 constraint members 3111, and the elastic damping component 32 is an elastic cable component 320 arranged in pairs inclined in the vertical direction. In the initial state before an earthquake occurs, the first core plate 3100, the first constraint member 3101, the second core plate 3110 and the second constraint member 3111 of the first layered energy-absorbing component 310 and the second layered energy-absorbing component 311 provide rigid support for the timber beam-column connection structure, maintain the rigid connection between the column 4 and the beam 5, and ensure that the timber beam-column connection structure is in a stable connection state. At this time, the elastic cable component 320 is in a tensioned state within the damping space 34.

[0082] When an earthquake occurs, the seismic waves transmitted to the wooden beam-column connection structure are mainly shear waves. When the shear waves are transmitted to the first damping component 31 and the elastic damping 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 31 of the first damping component 31 absorb part of the transmitted energy and convert 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 constraint member 3101, and between the second elastic layer 3112 and the second core plate 3110 and the second constraint member 3111, thereby dissipating vibration energy.

[0084] When the vibration intensity increases further, there may be a tendency for the two connecting plates 300 to break apart. At this time, the elastic cable component 320 will be stretched and undergo elastic deformation. During the elastic deformation process, the elastic cable component 320 can absorb part of the vibration energy (including the energy of the seismic shear wave and part of the seismic longitudinal wave), converting mechanical energy into elastic potential energy. At the same time, the damping force of the elastic cable component 320 overcoming the elastic deformation will also limit the breakage 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 restoring force of the elastic cable component 320 can be used to pull the deflected crossbeam 5 back to its initial state.

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

[0087] In another timber beam-column connection structure disclosed in this invention, taking the intermediate shock-absorbing part 3 of the timber beam-column connection structure as an example, in addition to the first shock-absorbing component 31 and the elastic shock-absorbing component 32 mentioned above, it also includes a rod-shaped shock-absorbing component 33 (the rod-shaped shock-absorbing component 33 includes a hydraulic support rod 330). The difference between the shock-absorbing effect of this structure and the structure mentioned above is that in the initial state before an earthquake occurs, the valve inside the hydraulic support rod 330 is closed and the liquid does not flow. Thus, the hydraulic support rod 330 also provides rigid support force for the timber 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 damping component 31 and the elastic damping component 32 is the same as that of the above-described structure.

[0089] As the vibration intensity continues to increase, the compressive or tensile force on the hydraulic support rod 330 may not yet reach the pressure value for opening the hydraulic support rod 330. The hydraulic support rod 330 remains in a locked state, acting as a support component between the two connecting plates 300 to prevent large deformation of the wooden 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 compression or tension applied to the hydraulic support rod 330 by the earthquake reaches the pressure value at which the hydraulic support rod 330 opens, fluid begins to flow inside 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] In summary, when the intermediate damping part 3 of the timber beam-column connection structure includes a rod-shaped damping component 33 in addition to the first damping component 31 and the elastic damping component 32, a three-level damping structure is formed. This structure integrates reliable connection, absorption of vibration energy, prevention of beam and column deformation under stress, and post-earthquake recovery functions, resulting in better damping effect and meeting the higher reliability, safety, stability, and anti-collapse performance requirements of timber structures.

[0093] In another specific embodiment of the present invention, such as Figures 10-13 As shown, the column connecting part 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 penetrate 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, on the one hand, increase the contact area between the column 4 and the crossbeam 5, and on the other hand, the blocking effect of the side wall of the column slot 10 on the column connector 11 can limit the deformation or misalignment of the column connector 11 due to earthquakes. The column connector 11 may include a column insertion plate 110 inserted into the column slot 10 and a column T-shaped plate 111 fixedly connected to the end of the column insertion plate 110. The column T-shaped plate 111 is composed of two mutually perpendicular plate-like structures, and one of the plate-like structures is connected to the middle of the other plate-like structure. One end of the column T-shaped plate 111, where the T-shaped tail is located, can extend into the column slot 10 and be fixedly connected to the column insertion plate 110 in the column slot 10 by 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 using 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. The side wall of the column slot 10 can prevent the column insertion plate 110 of the column connector 11 and the T-shaped tail of the column T-shaped plate 111 from deforming.

[0095] It should be noted that the column slot 10 can penetrate one side wall of the column 4, or it can penetrate two, three, or all four side walls of the column 4. 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, such as... Figures 10-13 As shown, the column slot 10 is cross-shaped and runs through the four side walls of the column 4. The corresponding column insertion plate 110 is also cross-shaped. The column insertion plate 110 can be composed of two intersecting plate-like structures. Figure 10 This represents the state where two plate-like structures are not connected. Figure 11 This refers to a state where two plate-like structures are intersected and connected. A column T-shaped plate 111 can be connected to each end of the cross-shaped column plug plate 110.

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

[0097] By using 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. The side wall of the beam slot 20 can prevent the T-shaped tail of the column T-plate 111 from deforming.
