The invention discloses a prefabricated wallboard supporting device for
housing construction. The device comprises a moving box, positioning plates are fixedly connected to the front position and the rear position of the left side of the top of the moving box correspondingly, a rotating shaft is rotationally connected to the opposite sides of the two positioning plates through bearings, and an L-shaped plate is fixedly connected to the left side of the rotating shaft. By arranging the L-shaped plate, the sliding rail, the sliding plate and the limiting bolt, the supporting plate can move, by arranging the structure, the supporting device has the
advantage that the supporting position can be adjusted when the supporting device is used, the problem that the supporting position cannot be adjusted when an original supporting device is used is solved, and therefore the supporting effect is prevented from being affected. Through the arrangement of the positioning plate, the rotating shaft, the screw rod, the sleeve, the sliding column, the sliding cylinder, the bearing plate and the push plate, the L-shaped plate can rotate conveniently, through the arrangement of the structure, the supporting device has the
advantage that the supporting angle can be adjusted when the supporting device is used, and therefore the supporting effect is further prevented from being influenced.
