Reinforced concrete prefabricated part splicing structure

The utility model relates to the technical field of fabricated buildings, and discloses a splicing structure of reinforced concrete prefabricated components. A cushion block is installed at the edge position of the prefabricated part B, and a mortar cushion layer is evenly laid on the upper surface of the groove of the prefabricated part B; the prefabricated part A and the prefabricated part B are accurately positioned and spliced together, the protruding blocks of the prefabricated part A and the grooves of the prefabricated part B are mutually embedded and fixed, the mortar cushion layer is compacted, and meanwhile main reinforcements in the peripheral areas of the prefabricated part A and the prefabricated part B are alternately inserted into the inner sides of the stirrups in a staggered mode; an outer formwork is installed, and ultrahigh-strength concrete is poured into the splicing connector to fill the peripheral post-pouring area; and after the ultrahigh-strength concrete is solidified to reach the sp
