The invention discloses an extensible lifting construction platform which comprises at least one frame body. Each frame body comprises a scaffold board, a protecting screen frame and at least two parallel vertical rods, each scaffold board is detachably connected with the corresponding vertical rods, and each protecting screen frame is fixed on the outer sides of the corresponding vertical rods. The extensible lifting construction platform is characterized in that a first extensible scaffold board is arranged in at least one side of each scaffold board, and each protecting screen frame comprises a first extensible protecting screen frame arranged in the corresponding protecting screen frame and positioned on a same side with the corresponding first extensible scaffold board. Aiming at the problem that a whole construction frame body externally surrounding an external wall cannot change along with the external wall after assembling of an existing construction platform is completed, the extensible lifting construction platform which is automatically extensible in the process of ascending and descending, needless of manual operation and adaptable to changing of a main structure of a building is provided.
