The manufacturing method of the steel-concrete combined stair further comprises the following steps: the pedal plate comprises a vertical plate and a transverse plate which are integrally formed; in the adjacent riser of stepping on, step on the diaphragm upper surface of riser and step on the riser top parallel and level of riser down.
The manufacturing method of the steel-concrete combined stair further comprises the following steps: the positioning nail is arranged at the bottom of the pedal and is abutted against one side of the vertical plate.
The manufacturing method of the steel-concrete combined stair further comprises the following steps: the pedal is specifically a steel plate or a wood plate and is positioned between the two steel oblique beams.
The manufacturing method of the steel-concrete combined stair further comprises the following steps: the concrete is poured below the pedal and wraps the concrete reinforcing steel bars.
Compared with the prior art, the invention has the following beneficial effects:
1. the steel members (the steel inclined beams and the pedal plates) in the manufacturing method of the steel-concrete combined stair are only used as a part of templates in the process of cast-in-place, the stress is not considered, the steel wrapped outside can be free from fire prevention treatment, the influence on the appearance problem is small, and decoration treatment is not needed.
2. The manufacturing method of the steel-concrete combined stair disclosed by the invention is a steel stair in a construction stage, meets the construction requirement, only takes the reinforced concrete into consideration in the strength and the basic rigidity in a use stage, and the steel member is only a decorative outer package, so that the construction is greatly facilitated, and the construction period of a site is greatly shortened.

[ detailed description ] embodiments
Referring to the attached drawings 1 to 3 in the specification, the invention relates to a manufacturing method of a steel-concrete combined stair, which comprises the following process steps:
1) an L-shaped pedal plate 2 is welded on the inner side of the steel oblique beam 1;
2) concrete reinforcing steel bars 4 are laid on the lower parts of the oblique steel beams 1;
3) a pedal 3 is laid on the treading plate 2 and is positioned by a positioning nail 6;
4) hanging a lower template 7 by using the steel oblique beams 1 at two sides as templates of the cast-in-place reinforced concrete bench;
5) and pouring concrete 5, and then curing to finally form the steel-concrete combined stair.
Wherein, the steel sloping 1 is obliquely arranged on two sides and is parallel to each other. In the present embodiment, the steel stringer 1 is a standardized section steel, specifically an H-section steel, which can be used as a stringer of a building and also as a side template of a staircase.
In the step 1), the treading vertical plates 2 on the two steel oblique beams 1 are arranged correspondingly. The step-up plate 2 is L-shaped and comprises a vertical plate 21 and a transverse plate 22 which are integrally formed. In the adjacent riser 2 of stepping on, the bottom of stepping on riser 2 and the top parallel and level of stepping on riser 2 down, the diaphragm 22 upper surface of stepping on the riser promptly and the riser 21 top parallel and level of stepping on the riser down to guarantee that footboard 3 lays the level.
