Description
Technical Field
[0001] The utility model belongs to the technical field of repair and reinforcement of ancient building structures, and in particular relates to a reinforcement device for mortise and tenon joints of ancient building wooden structures. Background Art
[0002] my country's traditional ancient buildings have a long history, among which wooden structures are unique. With their exquisite craftsmanship and unique aesthetic value, they have become a treasure of ancient Chinese architectural art and have extremely high cultural relic protection value. However, due to the long construction period of these buildings, the wood itself is susceptible to moisture and decay. In addition to the influence of natural factors such as wind and rain erosion and human factors such as improper repair, the overall structure of the building is easily damaged, especially at the key mortise and tenon joints; as an important connection part of wooden structures, the stability of mortise and tenon joints is directly related to the stability of the entire building. Therefore, it is an indispensable part of cultural relic protection to propose effective reinforcement devices for the mortise and tenon joints of wooden structures of ancient buildings.
[0003] Common methods for reinforcing mortise and tenon joints include flat steel, iron nails, angle steel, and fiber cloth reinforcement. Flat steel reinforcement is prone to corrosion in the natural environment, which can easily cause secondary damage to wooden components; iron nail reinforcement often rusts and punctures the main components of cultural relics, polluting and damaging the components, which does not conform to the principles of cultural relics protection and repair, and the mechanical performance improvement is limited; angle steel and fiber cloth reinforcement can play a good limiting role, but the mortise and tenon joints consume energy through friction rotation, and it is not possible to only pursue stiffness improvement. Fiber cloth is not practical when the node structure is complex. Therefore, when reinforcing the nodes, the principle of minimum interference must be followed to ensure its energy consumption capacity. It is necessary to propose a device for reinforcing the mortise and tenon joints of ancient building wooden structures to solve the problem of mortise and tenon joint damage. Utility Model Content
