The invention discloses a building tower crane frame. A base of the building tower crane frame is fixed in a manner that first inner conical holes in the middle are matched with outer conical surfaces at lower ends of supporting columns and the outer conical surfaces of the supporting columns are matched with inner conical surfaces of second inner conical holes of square frames; after the inner conical holes and the outer conical surfaces are matched to be fixed, the inner conical surfaces and the outer conical surfaces, well clung to one another, are automatically locked by matching locking grooves in the inner conical surfaces with locking ends of straight rotary locks, and a rotary plate of a tower crane is connected with the uppermost square frame. The building tower crane frame is simple in structure and very convenient to manufacture, mount and use, and can be mounted without tools; after the building tower crane frame is adopted, the tower crane frame is convenient, quick, safe and reliable to mount, the mounting time of the tower crane frame is shortened, the cost and the labor intensity for mounting and constructing the tower crane frame are reduced, and the efficiency for mounting and constructing the tower crane is improved; when the position of the tower crane needs to be changed, dismounting and transportation are convenient, and the building tower crane frame can be repeatedly utilized, so that the production cost and the use cost are reduced.
