Description

Ancient building timber beams tenon repair reinforced structure

Technical Field

The utility model relates to the technical field of ancient architecture repair, in particular to a reinforcing structure for repairing a tenon of a wooden beam of an ancient architecture.

Background

In the using process of the historic building wood structure, the wood is easy to decay, crack, moth-eaten and the like due to long-term loading, so that the performance of the wood structure is reduced to different degrees, and finally the damage occurs. The tenon-and-mortise joint is used as the most important connection mode in the wood structure, under various load actions, the tenon often bears complex external forces such as stretching, extrusion, bending and shearing, and the like, and the wood is easy to be affected by material characteristics such as moisture, so that structural damage such as decay and the like can occur to the tenon easily, and once the tenon is removed or the tenon is broken, the connection between the beam columns can be weakened, so that the structural integrity and the stability are further affected. At present, single methods such as CFRP cloth reinforcement, hoop reinforcement, enucleation reinforcement and the like are mostly adopted in the industry to repair and reinforce mortise and tenon joints of a wood structure, but the reinforcing methods not only damage the original appearance of an ancient building, but also greatly reduce the rigidity of the repaired and reinforced joints compared with the original structure, and simultaneously are easy to cause secondary damage in the use process.

The prior art publication No. CN217925032U provides a reinforcing structure is repaired to ancient building timber beams tenon, the device is through the tenon part that has destroyed in the supplementary timber beams of enucleation, set up the recess that satisfies the atress demand in the inside of timber beams, install the replacement timber tenons in the mortise opening of timber beams and timber post, and pour into epoxy glue in the junction gap department, realize connecting through coupling assembling, still be provided with the diagonal bracing subassembly of opposite pulling simultaneously, not only consolidate the connection between replacement timber tenons and the timber beams, can also consolidate the connection between upper portion sparrow, lower part sparrow and the timber post, can realize the replacement reinforcement after the timber beams tenon destruction under the original outward appearance of protection ancient building, make replacement timber tenons can with timber beams zonulae occludens, structural rigidity of timber beams and the tenon of sparrow after having ensured the tenon replacement, the rigidity of tenon fourth of the mortise joint has been strengthened simultaneously and beam post system's overall stability, make timber beams head be difficult for breaking under the effect of earthquake load or other sudden load.

The above prior art solution, though realizing the beneficial effects related to the prior art by the structure of the prior art, still has the following drawbacks: in the process of reinforcing the tenons, the split bolts are required to be drilled and cut on the wood columns and the wood beams, the main body of the ancient building is damaged to a certain extent by the holes and the grooves, and corrosion of the wood columns and the wood beams is easy to accelerate in the air inlet holes which are moist outside after the holes are drilled, so that the structural strength of the wood columns and the wood beams is indirectly reduced.
