Steel stair formwork and constructing method for once pouring forming of building staircase
The invention discloses a steel stair formwork for once pouring forming of a building staircase and belongs to the field of building construction. The steel stair formwork comprises two inclined beams and a plurality of step side moulds, wherein the two inclined beams can be erected between an upper-layer stair landing and a lower-layer stair landing which are adjacent to each other. The two inclined beams can be arranged in parallel at interval, the two corresponding ends of the two inclined beams are fixedly connected through horizontal beams to form a formwork body, and height adjusting devices are arranged at the two ends of the formwork body. The step side moulds are sequentially fixed under the formwork body at intervals from top to bottom, the length of one step side mould is larger than the width of the formwork body, the same sides of the step side moulds are fully sealed through steel plates, and winged edges perpendicular to the steel plates are arranged at the tops of the steel plates. The steel stair formwork is convenient to install, simple to construct, easy to operate, capable of achieving simultaneous pouring of stairs and wall bodies of the staircase, capable of avoiding secondary embedded reinforcing steel bars, capable of guaranteeing the integrity of the staircase and capable of achieving tooled and standardized operation of staircase structure construction. The invention further discloses a constructing method for once pouring forming of the building staircase.
