Curtain wall keel and curtain wall

The invention relates to the field of building curtain walls, in particular to a curtain wall keel and a curtain wall, the curtain wall keel comprises a curtain wall panel, the curtain wall keel, a locking mechanism, a linkage mechanism and a threaded rod, the back of the curtain wall panel is connected with the curtain wall keel, a mounting cavity is formed in the curtain wall keel, the locking mechanism is arranged at one end of the curtain wall keel, and the linkage mechanism is arranged on the curtain wall keel. The threaded rod is fixed to the connecting plate, the curtain wall keel is used for supporting the curtain wall panel, and when the curtain wall keel is assembled, the linkage mechanism arranged on the curtain wall keel drives the locking mechanism to be in linkage, so that the sliding rod slides in the guide groove and drives the driving rod to be in linkage along with the track of the guide groove; the two adjacent curtain wall keels can be tightly attached to the connecting plate when connecte
