Prestressed steel reinforced concrete joint for turning part of zigzag column and frame beam

The invention provides a prestressed steel concrete node for a turning part of a zigzag column and a frame, the frame comprises a frame beam and a floor which are connected to the zigzag column, the frame beam comprises vertical plane beams and a straining beam, two adjacent vertical plane beams form a right angle, and the straining beam is located between the two vertical plane beams. The annular reinforced concrete column cap is arranged at the turning part of the zigzag column frame; the steel pipe sections are arranged in the column sections of the zigzag column and are connected with the center of the annular reinforced concrete column cap; the cross anchor plate is positioned in the frame beam and is in the same extension direction with the frame beam; one tail end of the cross anchor plate is welded on the outer surface of the connecting part of the steel pipe sections; the rib penetrating pipe penetrates through the joint of the steel pipe sections and is parallel to the extension direction of the str
