9. A construction method of an ancient architecture wood beam column mortise and tenon joint reinforcing structure is used for constructing the ancient architecture wood beam column mortise and tenon joint reinforcing structure according to any one of claims 2 to 8, and is characterized in that: the method comprises the following specific steps:
s1, carving lines, and carving grain curves matched with the prismatic concave parts (8) and the prismatic convex parts (9) on the end surface of the planed fir beam and the surface of the upright post (1) according to the proportion of a drawing;
s2, measuring and polishing, namely embedding the split prismatic concave part (8) and the prismatic convex part (9) with each other, measuring the excircle size of the joint part (4), acquiring the section size of the joint cavity (3) under ultrasonic scanning equipment, matching the section size with the excircle size, and polishing the joint part (4) according to the obtained tolerance;
s3 splicing and assembling, namely, placing the two cross beams (2) on two sides of the upright post (1) respectively, arranging the two cross beams (2) in a central symmetry manner in an inclined manner, then synchronously approaching the connecting blocks (7) at the end parts of the cross beams (2) to the upright post (1), enabling the end parts of the connecting parts (4) to move into the connecting cavity (3), keeping the outer surfaces of the connecting parts (4) to be attached to the inner wall of the connecting cavity (3), and then synchronously rotating the cross beams (2) to realize splicing of the end parts of the two cross beams (2) in the upright post (1);
s4, reinforcing and limiting, namely enabling the beam-bearing column (11) to penetrate through the connecting part (4) and the upright column (1) along a column hole, attaching the reinforcing block (5) to the surface of the cross beam (2) and embedding the reinforcing block into the movable groove (14) in a displacement mode, embedding the embedding part (10) into the embedding groove, and finally inserting the fulcrum pin shaft (6) to limit the horizontal displacement of the reinforcing block (5);
s5 surface protection, wherein anthracene oil is coated at the communicated joint of the surfaces of the upright post (1) and the cross beam (2) by adopting a mode of firstly spraying and then rolling.
