Pluggable piece for pipeline integrated prefabricated fast-assembly keel system

The utility model relates to a pluggable piece for a pipeline integrated prefabricated fast-assembly keel system, which is installed on a special-shaped section bar and comprises a main body part andtwo clamping parts. The two clamping parts are arranged on the two opposite sides of the main body part respectively and incline towards the inner side of the main body part. Wherein the main body part and the two clamping parts jointly form a clamping groove. At least one connecting part is arranged on the special-shaped section bar in the length direction of the special-shaped section bar and extends to the two ends of the special-shaped section bar. And the outline of the transverse section of the clamping groove is matched with the outline of the transverse section of the connecting part.And when the connecting part is inserted and embedded in the clamping groove, the connecting part is not easy to fall off from the clamping groove, so that the plugging piece can be stably mounted onthe special-shaped sectiona
