Automatic building construction platform

The invention relates to the technical field of construction platforms, in particular to an automatic building construction platform. The invention provides an automatic building construction platform capable of expanding the construction space. An automatic building construction platform comprises an automatic construction platform body, an expansion mechanism and a connecting mechanism, the expansion mechanism used for expanding construction space is arranged on the automatic construction platform body, and the connecting mechanism used for fixing the expansion mechanism is arranged between the automatic construction platform body and the expansion mechanism. The external plate frames are installed on the two sides of the automatic construction platform, the motor is started, the output shaft of the motor drives the isolation safety plate frame to rotate to clamp the external plate frames, and the limiting plate rotates to limit the external plate frames, so that the expansion effect is achieved, and constr
