In the second and third modes, since the window frame area of the window frame and the door frame area of the door frame are generally large, in order to increase the strength of such a keel unit 1, the keel unit 1 further includes a third supporting member 18, as shown in fig. 4 to 5, one end of the third supporting member 18 is connected to the top corner of the keel frame 1, and the other end is connected to the intersection of the first supporting member 17 and the second supporting member 18, and the top corner and the intersection are located in the same quadrangle and outside the window frame or the door frame.
