10. A construction method of a self-locking structure column base system is characterized by comprising the following steps:
s1, manufacturing a tenon (310) and a mortise (320): firstly, determining the steel number and specification of raw materials, then sequentially performing lofting, numbering, cutting, correcting and forming to manufacture a tenon plate (330) and an inclined tenon groove (340) with required specifications, and then respectively fixing the tenon plate (330) and the inclined tenon groove (340) at two ends of a cross beam, a gap between two C-shaped steel structures (321) and the inner side wall of the C-shaped steel structure (321);
s2, connecting the steel member with the connecting piece: welding the to-be-connected end of the inclined tenon groove (340) in the gap of the tenon groove (320), and completely removing welding seams, welding slag on two sides of the welding seams, splashing, welding flashes and the like after welding is finished;
s3, ultrasonic flaw detection: after each welding link in the production and processing process is finished, all welding seams are detected by using an ultrasonic flaw detection technology, so that the welding quality is ensured to be good;
s4, component transportation: the components which are finished in production, processing and detection are completely packaged and then are transported to a construction site from a factory building;
s5, mortise and tenon connection: the tenon (310) is inserted into the bottom of the mortise (320) from the opening at the upper end of the mortise (320) through hoisting operation, so that the tenon is clamped in position, the tenon plate (330) and the inclined tenon groove (340) are mutually and tightly buckled, and the horizontal limiting part (331) and the positioning bulge (332) are respectively in corresponding contact with the horizontal positioning part (341) and the positioning recess (342) along the tenon plate (330) and the inclined tenon groove (340) and are mutually clamped;
s6, bolt connection: the tenon-and-mortise components (300) are connected by adopting the high-strength bolts (500), so that the tenon (310) is further limited to slide in the mortise (320), and the connection is ensured to be firm.
