Door-type scaffold stable base

The utility model discloses a door-type scaffold stable base which comprises a longitudinal beam and a cross beam, inserting cores are symmetrically welded to the side faces of the longitudinal beam, the longitudinal beam is connected with the cross beam in an inserted mode through the inserting cores, frame body inserting columns are further assembled on the longitudinal beam and used for being connected with a door-type scaffold in an inserted mode, and first inserting holes are formed in the side faces in the length direction of the inserting cores. Second insertion holes penetrating through the rear surface of the cross beam are formed in the two ends of the front surface of the cross beam, when the cross beam is connected to the insertion core in a sleeving mode, the first insertion holes coincide with the second insertion holes, insertion pins are inserted into the second insertion holes, and when the second insertion holes coincide with the first insertion holes, the insertion pins penetrate through th
