The invention discloses an annulated column cap embedded part. The annulated column cap embedded part comprises an embedded steel plate and an anchor bar. The embedded steel plate is provided with vibration holes and vent holes, the vibration holes and the vent holes are evenly distributed, and after the casting and compacting of concrete, the vibration holes are patched through small equal-thickness circular steel plate grooves made of the same materials in a plug welding mode and rubbed down; lower rectangular embedded parts are embedded into the lower surface of a column cap and symmetrically arranged in a cross mode. The invention discloses a construction method of the annulated column cap embedded part. The construction method comprises a positioning control measure and a fixing measure. The accurate anchor bar positioning is guaranteed through partial anchor bar and embedded part synchronous construction, and the construction quality is guaranteed by carrying out multiple bearing, rechecking, checking and accepting in all stages of the whole process, arranging the vent holes in a board of the embedded part. After being finished, the embedded part is firmly fixed, the structural sizes are in the deviation range allowed by the job specifications, and various testing results meet the requirements.
