The reinforcing structure for mortise and tenon joints of ancient building wood beams and columns according to claim 7, wherein: the prismatic concave part (8) and the prismatic convex part (9) are respectively provided with a prismatic groove (12) and a prismatic strip (13) with the same cross section shape, and the cross sections of the prismatic groove (12) and the prismatic strip (13) are V-shaped along the edges of the prismatic concave part (8) or the prismatic convex part (9).
9. A construction method of a reinforcing structure for mortise and tenon joints of ancient building wood beams and columns, which is characterized in that the reinforcing structure for mortise and tenon joints of the ancient building wood beams and columns is constructed according to any one of claims 2-8, and is characterized in that: the method comprises the following specific steps:
s1, scribing and carving, namely, scribing and carving a line curve matched with a prismatic concave part (8) and a prismatic convex part (9) on the end surface of the shaved fir beam and the surface of the upright post (1) according to the proportion of a drawing;
s2, measuring and polishing, namely mutually embedding the divided prismatic concave parts (8) and the prismatic convex parts (9), measuring the outer circle size of the connecting parts (4), acquiring the section size of the connecting cavity (3) under ultrasonic scanning equipment, matching with the outer circle size, and polishing the connecting parts (4) according to the obtained tolerance;
s3, splicing and assembling, namely respectively placing the two cross beams (2) on two sides of the upright post (1), obliquely arranging the two cross beams (2) to be arranged in a central symmetry manner, 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 be displaced into the connecting cavities (3), keeping the outer surfaces of the connecting parts (4) to be attached to the inner walls of the connecting cavities (3), and synchronously rotating the cross beams (2) to realize the splicing of the end parts of the two cross beams (2) in the upright post (1);
s4, reinforcing and limiting, namely enabling a beam bearing column (11) to penetrate through the connecting part (4) and the upright column (1) along a column hole, enabling a reinforcing block (5) to be attached to the surface of the cross beam (2) and to be embedded into the movable groove (14) in a displacement mode, enabling the embedded part (10) to be embedded into the embedded groove, and finally inserting a fulcrum pin shaft (6) to limit the horizontal displacement of the reinforcing block (5);
s5, surface protection, namely smearing anthracene oil at the surface communication joint of the upright post (1) and the cross beam (2) in a mode of spraying and then rolling.
