The invention provides a steel pipe movable bracket for construction and belongs to the field of construction. The steel pipe movable bracket includes a main rod body. The middle of the main rod bodyis provided with a circular cavity. Two semi-arc movable rods are sleeved inside the circular cavity and are in bilateral symmetry; and the lower ends of the two semi-arc movable rods are fixedly connected with two springs through arc shapes. The outer sides of the lower ends of the semi-arc movable rods are inclined towards the two sides and fixedly connected with two supporting rods. The two supporting rods penetrate first sliding grooves, and the first sliding grooves are formed in the lower end face of the main rod body. The semi-arc movable rods facilitate arc-shaped rotation in the circular cavity. When the two semi-arc movable rods rotate downwards, the semi-arc movable rods facilitate spring compression. Fixing blocks facilitate fixation of the two springs. When the two semi-arc movable rods rotate downwards simultaneously, the semi-arc movable rods drive the two supporting rods to rotate towards the middle, to enable the supporting rods to jack up a whole device. The supporting rods facilitate the rotation in the first sliding grooves.
