Building formwork placing method

The invention belongs to the technical field of aluminum alloy formwork manufacturing, and discloses a building formwork placing method. The method comprises the following steps of S1, installation drawing making, wherein placing installation drawings are made by splitting based on the house type according to a coding general drawing; and S2, stairway placing, wherein stairway formworks are placedin a half-placing manner according to the placing installation drawings. Compared with the prior art, the method adopts the placing mode, different parts are placed on the ground, the completeness ischecked on the ground after each part is placed, the designing, machining and assembling problems are checked and rectified, and coding and packaging are performed according to the placing positionsafter the problems are rectified. The method has the advantages that actual preassembling is not needed, the parts such as walls, floors, beams, stairways and windows can be placed on the ground, theworkload of carrying, assemb
