Description

Technical Field

[0001] The invention relates to the technical field of wood structures, in particular to a metal damping plate reinforcement device for wood structures. Background Art

[0002] Ancient buildings are important carriers of history and culture. Their structural joints are susceptible to damage and degradation due to long-term natural erosion, human influence, and dynamic forces such as earthquakes, leading to a decrease in overall structural stability and safety. Traditional methods for reinforcing ancient building joints often cause significant damage to the original appearance of the buildings and have limited effectiveness. Therefore, there is an urgent need for a reinforcement technology that can effectively improve the seismic resistance and other performance of ancient building joints while minimizing the impact on the buildings themselves.

[0003] The mortise and tenon joint, a key component of the timber structure of ancient buildings, is distinct from modern building joints. It not only possesses excellent rotational capabilities but can also withstand certain bending moments, exhibiting unique mechanical properties. Currently, the node reinforcement technology for timber structures of ancient buildings mainly relies on carbon fiber cloth and metal connectors. However, there are significant differences in the seismic performance of different reinforcement methods. While carbon fiber cloth reinforcement can improve the seismic performance of the joint to a certain extent, it restricts the rotation of the joint, conflicting with the original mechanical properties of the mortise and tenon joint, resulting in unsatisfactory reinforcement results and obvious limitations in actual engineering applications. Metal connectors exhibit the best reinforcement effect compared to carbon fiber cloth. However, in actual use, metal connectors are prone to material yielding and corrosion, which not only affects their reinforcement effect but also poses a threat to the long-term stability of the timber structure of ancient buildings.

[0004] None of these traditional reinforcement methods fully meet the "minimum intervention" reinforcement principle for ancient wooden structures. This principle requires preserving the original appearance and structural characteristics to the greatest extent possible while improving the seismic performance of ancient buildings. Therefore, to better protect ancient buildings, there is an urgent need to develop more scientifically sound and effective metal damping plate reinforcement devices that can effectively meet the stringent seismic requirements of ancient wooden structures.

[0039] Figure 1 1 is a schematic structural diagram of a metal damping plate reinforcement device 100 for a wooden structure according to an embodiment of the present invention, viewed from one angle. Figure 2 FIG. 1 is a schematic structural diagram of a metal damping plate reinforcement device 100 for a wooden structure according to an embodiment of the present invention from another angle. Figure 3 FIG is a schematic structural diagram of a metal damping plate 30 according to an embodiment of the present invention. Figures 1 to 3 As shown, in some embodiments, a timber structure includes a timber column 300 and a timber beam 200 connected by a mortise and tenon joint. The timber column 300 is arranged vertically, and the timber beam 200 is arranged horizontally. The metal damping plate reinforcement device 100 for the timber structure includes a first reinforcement plate 10, a second reinforcement plate 20, and a plurality of metal damping plates 30. One end of the first reinforcement plate 10 is pivotally connected to the bottom end of the timber beam 200, and the other end extends obliquely downward toward the timber column 300. One end of the second reinforcement plate 20 is pivotally connected to the side end of the timber column 300, and the other end extends obliquely upward toward the timber beam 200. The plurality of metal damping plates 30 are arranged parallel to and spaced apart between the first reinforcement plate 10 and the second reinforcement plate 20 along the extension direction of the first reinforcement plate 10. The ends of the plurality of metal damping plates 30 are respectively connected to the first reinforcement plate 10 and the second reinforcement plate 20.

[0040] This embodiment offers significant advantages over conventional reinforcement methods for ancient buildings. Conventional reinforcement methods primarily enhance connection strength, such as using nails and steel bars. These methods rely primarily on their own strength to resist external forces, but have limited impact on energy dissipation. In this embodiment, the metal damping plate 30 actively absorbs and dissipates energy generated by earthquakes, wind loads, and other factors through its own deformation, significantly reducing the stress and deformation of the joints under dynamic loads, effectively improving the structure's seismic resistance and better protecting the wooden structure from disasters such as earthquakes.

[0041] This embodiment can install the metal damping plate reinforcement device 100 inside the nodes of ancient buildings or in hidden gaps, such as inside the mortise and tenon joints of wooden structures, the interlayer of masonry walls, etc., without damaging the appearance of the building, and can also protect the metal damping plate reinforcement device 100 with the help of the original structure.

[0042] See also Figures 1 to 3 As shown, the width of the middle portion of the metal damping plate 30 is smaller than the width of the two side portions. The cross-sectional area of ​​the metal damping plate 30 gradually increases from the middle portion of the metal damping plate 30 toward the ends of the metal damping plate 30.

[0043] In some embodiments, the metal damping plate 30 is made of low-yield point alloy steel, which has a continuous yield platform characteristic and an elongation of ≥25%, ensuring plastic deformation capability. Trace alloy elements are added to the steel to form a nano-precipitation strengthening phase, which can improve the material's fatigue resistance.

[0044] In some embodiments, the middle sections of the two opposing sides of the metal damping plate 30 are arc-shaped. The geometry of the metal damping plate 30 in this embodiment must satisfy the golden ratio between the arc length and arc height of each arc segment, ensuring uniform stress distribution. Multiple metal damping plates 30 are arranged in a linear array, and the center-to-center spacing between adjacent metal damping plates 30 can be determined through finite element optimization, thereby creating an energy dissipation belt effect.

[0045] Specifically, the curvature of the metal damping plate 30's sides is determined through seismic wave response analysis, ensuring that the principal stress direction aligns with the node shear failure surface. Furthermore, the flange-to-web thickness ratio of the metal damping plate 30 is determined through energy efficiency optimization, forming a progressive yield sequence.

[0046] In some embodiments, the metal damping plate 30 is arranged perpendicular to the first reinforcement plate 10 and the second reinforcement plate 20. In other embodiments, the metal damping plate 30 can also be arranged obliquely relative to the first reinforcement plate 10 and the second reinforcement plate 20, depending on design requirements.

[0047] In some embodiments, the first reinforcing plate 10 is arranged parallel to the second reinforcing plate 20. The installation angle between the first reinforcing plate 10 and the wooden beam 200 is in the range of 40° to 50°, for example, 40°, 45° or 50°.

[0048] In some embodiments, both ends of the metal damping plate 30 are fixedly connected to the first reinforcing plate 10 and the second reinforcing plate 20. Here, the metal damping plate 30 can be fixedly connected to the first reinforcing plate 10 and the second reinforcing plate 20 by welding.

[0049] In some embodiments, the first reinforcement plate 10 and the second reinforcement plate 20 have the same thickness. Here, the thickness of the first reinforcement plate 10 and the second reinforcement plate 20 can be determined by stress flow analysis to ensure that the first reinforcement plate 10 and the second reinforcement plate 20 do not buckle under seismic loads.

[0050] In some embodiments, a first preset distance is provided between an end of the first reinforcing plate 10 away from the wood beam 200 and the wood column 300, and a second preset distance is provided between an end of the second reinforcing plate 20 away from the wood column 300 and the wood beam 200. The first preset distance ranges from 350 mm to 480 mm, such as 350 mm, 400 mm, 450 mm, or 480 mm, and the second preset distance ranges from 350 mm to 480 mm, such as 350 mm, 400 mm, 450 mm, or 480 mm, etc.

[0051] The setting of the first preset distance and the second preset distance needs to meet the following requirements: the first preset distance and the second preset distance can be determined by mechanical calculation to form an effective force transmission path, ensuring that the node load is evenly transmitted to the metal damping plate 30 through the first reinforcement plate 10 and the second reinforcement plate 20, avoiding local stress concentration on the wooden components and protecting the integrity of the wood fiber structure. In addition, it needs to comply with traditional architectural aesthetic requirements and be flush with the surface of the wooden components or form a coordinated visual effect.

[0052] In some embodiments, the spacing between two adjacent metal damping plates 30 in the plurality of metal damping plates 30 is any value between 40 mm and 60 mm, for example, 40 mm, 50 mm, or 60 mm.

[0053] Figure 4 FIG1 is a schematic structural diagram of a metal damping plate reinforcement device for a wooden structure according to another embodiment of the present invention from one angle. Figure 5 is a schematic structural diagram of a metal damping plate reinforcement device for a wooden structure according to another embodiment of the present invention from another angle. Figure 6 FIG is a schematic structural diagram of a metal damping plate according to another embodiment of the present invention. Figures 4 to 6 As shown, in another embodiment, the metal damping plate 30 is triangular in shape.

[0054] In some embodiments, the metal damping plate 30 has a straight end and a pointed end, the straight end is fixedly connected to the second reinforcing plate 20 , and the pointed end is rotatably connected to the first reinforcing plate 10 .

[0055] In some embodiments, a plurality of spherical hinge supports 60 are provided on the first reinforcement plate 10, and the plurality of spherical hinge supports 60 are arranged at intervals, and each spherical hinge support 60 corresponds to a metal damping plate 30. The tip of the metal damping plate 30 is movably connected to the spherical hinge support 60. When the wooden structure is deformed due to external force, the tip can move and rotate freely within a certain range, which can effectively eliminate the membrane stress. Here, the metal damping plates 30 can be installed in combination with a specific arrangement, angle, and quantity according to the stress characteristics of the ancient building nodes, the characteristics of the building structure, and the actual reinforcement requirements. The spacing between two adjacent metal damping plates 30 can be determined according to the length of the first reinforcement plate 10 and the second reinforcement plate 20.

[0056] In some embodiments, a gasket is provided between the spherical hinge support 60 and the tip of the metal damping plate 30. The gasket can increase the contact area between the metal damping plate 30 and the spherical hinge support 60 and provide lateral restraint force, thereby improving the lateral stability of the metal damping plate 30 under complex forces, while allowing the tip of the metal damping plate 30 to move freely in the vertical direction to eliminate membrane stress.

[0057] In this embodiment, when an earthquake occurs, the metal damping plate 30 dissipates a large amount of seismic energy through its own repeated plastic deformation, greatly reducing the seismic force transmitted to the nodes of the ancient building and lowering the node bending moment demand. Finite element analysis shows that the peak value of the node bending moment under the action of seismic load can be reduced by 45%, which can ensure the safety of the wooden structure.

[0058] Figure 7 is a schematic structural diagram of a first connecting member 40 according to an embodiment of the present invention, Figure 8 FIG is a schematic structural diagram of a second connecting member 50 according to an embodiment of the present invention. Figure 7 and Figure 8 As shown, in some embodiments, the metal damping plate reinforcement device 100 further includes a first connector 40 and a second connector 50. The first connector 40 is mounted on the wooden beam 200 and is rotatably connected to the first reinforcement plate 10. The second connector 50 is mounted on the wooden column 300 and is rotatably connected to the second reinforcement plate 20. The first connector 40 and the second connector 50 each comprise two parallel flat steel bars. The flat steel bars are designed to conform to the shapes of the wooden beam 200 and wooden column 300 and wrap around the outer walls of the wooden beam 200 and wooden column 300, respectively. Bolt holes are provided at both ends of the flat steel bars, allowing bolts to penetrate and connect them. This is equivalent to using double C-shaped cold-formed steel bars to form a closed hoop, eliminating the need to penetrate the beam and column, thus preserving traditional manufacturing processes. Specifically, a 3 mm thick rubber padding is applied to the contact surfaces of the flat steel bars with the wooden beam 200 and wooden column 300. Here, the first reinforcement plate 10 is bolted to the bottom of the wooden beam 200, while the second reinforcement plate 20 is bolted to the side of the wooden column 300. The first connecting member 40 and the second connecting member 50 are made of Q235 steel, Q345 steel, Q390 steel or Q420 steel.

[0059] In some embodiments, the first connector 40 needs to be installed flush with the edge of the wooden beam 200, and the second connector needs to be installed flush with the edge of the wooden column 300, and the appearance needs to be coordinated with the traditional architectural style.

[0060] The metal damping plate 30 used in this embodiment has excellent durability, resisting environmental erosion and fatigue over long-term use while maintaining excellent mechanical properties. Furthermore, the metal damping plate reinforcement device 100 is easy to maintain. This requires only regular inspection of the fastening of the first and second connectors 40 and 50, as well as any deformation of the metal damping plate 30, and repair or replacement as necessary. This simple maintenance approach significantly reduces the cost and difficulty of historic building preservation and improves maintenance efficiency.

[0061] This embodiment also provides a wooden structure comprising wooden beams 200, wooden columns 300, and two metal damping plate reinforcement devices 100. The wooden beams 200 are arranged horizontally, and the wooden columns 300 are arranged vertically and connected to the wooden beams 200 via mortise and tenon joints. The two metal damping plate reinforcement devices 100 are installed on opposite sides of the wooden columns 300 and below the wooden beams 200.

[0062] In some embodiments, the installation angle between the two first reinforcement plates 10 and the wooden beam 200 ranges from 40° to 50°, and the two first reinforcement plates 10 are symmetrically arranged along the wooden column 300. This installation angle range is derived from force analysis and simulation calculations of wooden structures subjected to earthquakes. Within this installation angle range, the metal damping plate reinforcement device 100 can most effectively dissipate energy, converting earthquake energy into heat through the deformation of the metal damping plates 30, thereby reducing the stress and deformation of the joint and improving the seismic performance of the mortise and tenon joint.

[0063] In this embodiment, under the action of external loads such as earthquakes, the metal damping plate reinforcement device 100 effectively absorbs and dissipates energy through its own energy dissipation mechanism. Specifically, when the wooden frame is subjected to earthquake forces, the force is transmitted to the first connecting member 40 and the second connecting member 50 respectively through the wooden beam 200 and the wooden column 300, and then to the first reinforcement plate 10 and the second reinforcement plate 20 respectively, and finally to the metal damping plate 30. During the deformation process under stress, the metal damping plate 30 converts the earthquake energy into heat energy and consumes it, thereby reducing the stress and deformation of the node. In this way, this embodiment significantly improves the bearing capacity and seismic performance of the nodes of ancient buildings, and reduces the risk of damage to ancient buildings when disasters occur. After actual simulation experiments and engineering application verification, the mortise and tenon joints after adopting the metal damping plate reinforcement device 100 of this embodiment have significantly reduced displacement and stress under the same earthquake action, and the stability of the wooden structure has been greatly improved.

[0064] The installation instructions for the metal damping plate reinforcement device 100 are as follows:

[0065] 1. Scope of application

[0066] This installation instruction is applicable to the installation of a metal damping plate reinforcement device 100 for a wooden column and wooden beam structure connected by mortise and tenon joints. It can effectively improve the seismic performance of the wooden structure under dynamic loads such as earthquakes and wind loads, and protect the safety of the wooden structure.

[0071] Metal damping plates 30: Depending on the design quantity (e.g., 3-5), types include X-shaped and triangular metal damping plates. The X-shaped metal damping plate has a narrower center width than its two sides, and its cross-sectional area gradually increases from the center toward the ends. Its ends are welded to the first and second reinforcement plates 10, 20, respectively. The straight end of the triangular metal damping plate is fixed to the second reinforcement plate 20, while its tip is pivotally connected to the first reinforcement plate 10 via a spherical hinge. This requires a spherical hinge 60 and a gasket.

If not, adjust the positioning line.

[0086] (2) Installing the first connecting member 40 and the second connecting member 50

[0087] 1. Slide the first connector 40 onto the wooden beam 200. The first connector 40 consists of two parallel flat steel bars that wrap around the outer wall of the wooden beam 200. Bolt holes are provided at both ends of the flat steel bars, allowing bolts to penetrate and connect them, securing the first connector 40 to the wooden beam 200. A 3mm thick rubber pad is placed on the contact surface between the flat steel bars and the wooden beam 200.

[0088] 2. Similarly, the second connecting member 50 is mounted on the wooden column 300 and fixed with bolts in the same installation method as the first connecting member 40, and a rubber pad is provided on the contact surface.

[0091] 2. Rotate and connect one end of the second reinforcing plate 20 to the second connecting piece 50 , and extend the other end obliquely upward toward the wooden beam 200 to ensure that the first reinforcing plate 10 and the second reinforcing plate 20 are arranged parallel to each other.

[0092] (4) Installing metal damping plate

[0093] 1. According to the design requirements, a plurality of metal damping plates 30 are arranged between the first reinforcement plate 10 and the second reinforcement plate 20, and the distance between two adjacent metal damping plates 30 is 40 mm to 60 mm.

[0094] 2. If the metal damping plate 30 is X-shaped, mark the installation position of the metal damping plate 30 on the inside of the first reinforcement plate 10 and the second reinforcement plate 20. The spacing between adjacent metal damping plates 30 should be 40mm to 60mm, for example, 50mm. Use a tape measure to evenly distribute the spacing from the near ends of the first reinforcement plate 10 and the second reinforcement plate 20, ensuring that the center lines are aligned. Attach the ends of the metal damping plate 30 to the first reinforcement plate 10 and the second reinforcement plate 20, respectively, and temporarily secure them with a clamp. Weld the weld to a height of ≥ 6mm. Clean the weld slag and apply anti-rust paint after welding.

[0095] 3. If the metal damping plate 30 is triangular in shape, with a straight end and a pointed tip, weld the straight end of the metal damping plate 30 to the second reinforcement plate 20, ensuring a high-quality weld seam with a full, defect-free weld. The base width of each metal damping plate 30 should be consistent with the width of the second reinforcement plate 20. Bolt a spherical hinge support 60 to the first reinforcement plate 10. Insert a spacer plate between the spherical hinge support 60 and the pointed tip of the first reinforcement plate 10 to increase the contact area and provide lateral restraint while allowing the pointed tip to move freely vertically.

[0096] (5) Adjust the preset distance

[0097] Ensure that the first preset distance between the end of the first reinforcing plate 10 away from the wooden beam 200 and the wooden column 300 is within the range of 350mm to 480mm, and the second preset distance between the end of the second reinforcing plate 20 away from the wooden column 300 and the wooden beam 200 is also within the range of 350mm to 480mm.

[0098] 4. Debugging and Testing

[0099] (1) Functional testing

[0100] 1. Perform an appearance inspection on the installed metal damping plate reinforcement device 100 to check whether the connections of the components are firm and whether there is any looseness or deformation.

[0101] 2. Simulate the effects of dynamic loads such as earthquakes and wind loads to observe the working status of the metal damping plate reinforcement device 100, check whether the metal damping plate 30 can effectively absorb and dissipate energy through its own deformation, and whether the stress and deformation of the wooden structure nodes are significantly reduced.

[0102] (2) Troubleshooting of Common Problems
