Embodiment 1

[0025] Reinforcement and repair of the Dougong structural layer at the outer eaves of ancient buildings: Due to long-term wind and sun exposure in the outer eaves of the Dougong structural layer, it is common for the tenons of the Dougong to break and decay. This patented technology can be used to repair the fracture or The rotten part is cut off, and then made with dry hard miscellaneous wood according to the size of the original tenon. The length should be 1-2 times longer than the old one. Grooves were made at the joints on the facade of the gong to embed silver ingot tenons to fix the hard miscellaneous wood and the gong head. Torsion and bending resistance, thereby improving the stress state of the gong and improving the overall performance of the gong.

Embodiment 2

[0027] Reinforcement and repair of the dougong structure layer at the corner column head of ancient buildings: the damage of the dougong structure layer in the corner dougong mostly reflects the severe torsional deformation in the middle. For this, the patented technology can be used to saw off the torsional deformed part and use dry hard miscellaneous wood Manufactured according to the original tenon style and size, the length should be 1-2 times longer than the old one. The two ends of the hard miscellaneous wood are connected with the dovetail tenon and the gong head tenon. The hard miscellaneous wood is fixed with the gong head, which fundamentally improves the stress state of the gong and improves the torsion resistance of the gong.

Embodiment 3

[0029] Reinforcement and repair of the inner eaves Dougong structure layer of ancient buildings: the inner eaves Dougong structure layer often causes the mortise and tenon fracture of the eaves truss. This patented technology can be used for reinforcement and repair. First cut off the fractured part, and then use dry The hard miscellaneous wood is made according to the original tenon style and size, and the length should be 1-2 times longer than the old one. The grooves on the surface are embedded with silver ingot tenons to fix the hard miscellaneous wood and the dovetail. The dovetail tenon at both ends of the hard miscellaneous wood can enhance the pulling force between it and the dome. The embedded silver ingot tenon can improve the torsion and bending resistance of the dome.

Abstract

Provided is a reinforcing and repairing method for a Dougong of a historic building. If the tenon of the Dougong is cracked, twisted or rotten, the cracked, twisted or rotten portion of the tenon can be removed firstly, then, a piece of dry hardwood is used for manufacturing the removed part according to the type and the size of the original tenon, the length of a newly-manufactured part should be larger than that of the original tenon by once to twice, dovetail joints are formed in the two ends of the hardwood so that the head of the Dougong can be connected with the hardwood through the dovetail joints, a groove is formed in the vertical face where the head of the Dougong is combined with the hardwood so that a silver ingot tenon can be embedded in the groove, the outer surface of the silver ingot tenon is made to be flush with the surface of the Dougong, the hardwood can be fixed to the head of the Dougong through the silver ingot tenon, and the bending resistance and the twisting resistance of the Dougong body can be improved. The joint of the Dougong body is made to be flat through caulking of putty, and then the surface of the Dougong is painted with wood oil.

Description

technical field [0001] The invention relates to the protection and repair of the beam frame structure of the ancient building, in particular to the reinforcement and repair treatment of the dougong in the dougong structure layer of the ancient building without changing the raw materials and the construction technology. Background technique [0002] Dougong components in ancient buildings have the largest number of components, and they are small components with complex and varied structures. The components are overlapped with each other, sawed and chiseled, and the remaining effective cross-sections are generally very small. Due to the external force of the entire Dougong, such as the outward rolling of the eaves, the sinking of the columns, and the skewing of the beam frame, etc., all components of the Dougong will be displaced due to uneven force, and twisting, flashing and deformation are often accompanied by The mortise is squeezed and the tenon is broken. [0003] Most ...
