Description

Technical Field

[0001] This utility model relates to the field of ancient building protection technology, specifically a device for reinforcing the joints of ancient building wooden structures. Background Technology

[0002] Ancient wooden structures, as a treasure of my country's traditional architectural culture, carry rich historical and cultural value. However, due to their age, the joints of these structures have been subjected to long-term erosion from the natural environment, insect infestation, wood aging, and human factors, resulting in decreased wood strength and loosening of mortise and tenon joints, seriously threatening the structural safety of ancient buildings. Currently, common methods for reinforcing the joints of ancient wooden structures mainly include traditional mortise and tenon repair and chemical bonding reinforcement. Traditional mortise and tenon repair relies on exquisite manual skills, is difficult and time-consuming, and has limited effectiveness in repairing severely damaged joints. While chemical bonding reinforcement is relatively simple to operate, chemical adhesives may cause irreversible damage to the wood of ancient buildings, which does not conform to the principle of "restoring the old as it was." Furthermore, the durability of chemical materials cannot guarantee long-term reinforcement effects. Therefore, it is necessary to design a reinforcement device for the joints of ancient wooden structures. Utility Model Content

[0028] Please see Figures 1-3 This utility model discloses a reinforcement device for the joint of ancient building wooden structure, including a ring-type reinforcement component, a shock-absorbing buffer component 1, an adaptive adjustment component and a limiting snap-fit ​​structure.

[0029] The encircling reinforcement component includes a first arc-shaped metal hoop 2 and a second arc-shaped metal hoop 3. The first arc-shaped metal hoop 2 has a first protruding edge 4 at both ends, and the second arc-shaped metal hoop 3 has a second protruding edge 5 at both ends. Both the first protruding edge 4 and the second protruding edge 5 have through holes. The first protruding edge 4 and the second protruding edge 5 are connected by a locking bolt 6. The first arc-shaped metal hoop and the second arc-shaped metal hoop are tightly attached to the outer wall of the wooden structure by locking with the locking bolt.

[0030] The shock-absorbing and buffering component 1 is installed between the wrap-around reinforcement component and the wooden component;

[0031] The adaptive adjustment component is installed on the outside of the first arc-shaped metal hoop 2 and the second arc-shaped metal hoop 3;

[0032] The limiting snap-fit ​​structure is installed at the ends of the first arc-shaped metal hoop 2 and the second arc-shaped metal hoop 3.

[0033] In this invention, the shock absorption and buffer assembly 1 consists of multiple shock absorption springs 7 and dampers 8. The shock absorption springs 7 are helical compression springs, which have good elasticity and shock absorption performance. The dampers 8 are viscous dampers, which can absorb and dissipate the energy generated by earthquakes or other external forces. The shock absorption springs 7 and dampers 8 are distributed at intervals inside the first arc-shaped metal hoop 2 and the second arc-shaped metal hoop 3. When the wooden structure vibrates under the action of external forces, the shock absorption springs and dampers can effectively buffer and absorb the vibration energy, reduce the relative displacement between wooden components, and protect the joints of the wooden structure.

[0034] In this invention, the adaptive adjustment component includes a mounting bracket 9, an adjusting screw 10, and an adjusting nut 11. The mounting bracket 9 is installed on the outside of the first arc-shaped metal hoop 2 and the second arc-shaped metal hoop 3. A threaded hole is provided in the middle of the mounting bracket 9. One end of the adjusting screw 10 passes through the threaded hole, and the other end of the adjusting screw 10 is threadedly connected to the adjusting nut 11. The tightness between the ring-shaped reinforcement component and the wooden component can be adjusted by rotating the adjusting nut. The adaptive adjustment component can adjust the clamping force of the reinforcement device in real time according to the actual deformation of the wooden component, ensuring that the reinforcement device is always in close contact with the wooden component and maintaining a good reinforcement effect.

[0035] In this utility model, the limiting snap-fit ​​structure includes a snap-fit ​​block 12 and a snap-fit ​​groove 13. The snap-fit ​​block 12 is installed at the outer end of the first protrusion 4, and the snap-fit ​​groove 13 is installed at the outer end of the second protrusion 5. The snap-fit ​​block 12 and the snap-fit ​​groove 13 are adapted to each other, and the arc-shaped metal hoop achieves initial positioning through the cooperation of the snap-fit ​​block and the snap-fit ​​groove.

[0036] In addition, in this utility model, the first arc-shaped metal hoop 2 and the second arc-shaped metal hoop 3 are both made of high-strength alloy material, and the inner side of the first arc-shaped metal hoop 2 and the second arc-shaped metal hoop 3 is provided with anti-slip protrusions that are adapted to the surface texture of the wooden component.

[0037] Working principle: In use, the arc-shaped metal hoops are first spliced ​​together, and their two ends are initially positioned by the cooperation of the locking blocks and slots. Then, using detachable connection structures such as high-strength bolts and nuts, they are spliced ​​around the wooden component to form a ring structure, thereby achieving a ring-like fixation of the wooden component. When the wooden component is subjected to vibration or external impact, the shock-absorbing spring can absorb some energy through its own elastic deformation, while the damper can consume vibration energy, slow down the transmission of vibration, and reduce damage to the wooden component. When the size or position of the wooden component changes due to environmental changes or other factors, the adjusting nut can be rotated to move it on the adjusting screw, thereby adjusting the tightness of the ring-like reinforcement component on the wooden component to adapt to the changes in the wooden component and maintain a good reinforcement effect.

[0038] In summary, this utility model has a novel structural design that can effectively reinforce the wooden structural nodes without damaging the original wooden structure of the ancient building, thereby improving the load-bearing capacity and stability of the nodes, extending the service life of the ancient building, and meeting the relevant requirements for the protection of ancient buildings.

[0039] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
