The invention discloses a construction process of a self-supporting cast-in-place reinforced concrete frame of an assembly rib mold, which comprises the following steps: processing a column and beam reinforcement cage into a reinforcement truss structure in a factory in advance, and the reinforcement cage comprises longitudinal and transverse reinforcements and inclined web reinforcements which are obliquely arranged; a formwork is hung outside the rigid reinforcement cage; during construction, column-beam rib mold prefabricated parts are assembled on site, and column-beam stress truss steel bars are welded and connected; construction is conducted floor by floor, and a three-step pouring construction method of pouring columns, then pouring beams and finally pouring plates can be adopted; b) a two-step construction method of pouring the columns and the beams to the slab bottom elevation once and then pouring the rest floor slab concrete; and after the concrete strength reaches the age, the formwork shell is re
