Novel stair steel formwork with adjustable combined size

The utility model discloses a novel stair steel template with adjustable combination size, which comprises a main beam, a mounting block is welded on the inner wall of the main beam, the inner side of the mounting block is connected with a support rod through a bolt, and a step positioning plate is arranged above the main beam. According to the utility model, a constructor can conveniently adjust the distance between a plurality of steps by changing the position relationship between the adjusting rods and the adjusting holes, so that the purpose of adjusting the width of the tread of the steps is achieved, and the constructor can change the distance between the two main beams by replacing the supporting rods with different lengths, so that the construction efficiency is improved. According to the stair steel formwork, the purpose of conveniently adjusting the length and the height of the steps by replacing the steps with different lengths and heights is achieved, so that the practicability of the stair steel
