It has many advantages in structural rigidity, fire resistance, cost, construction and modeling, and is most commonly used. The construction methods of reinforced concrete stairs are three types of integral cast, prefabricated, partially cast and partially prefabricated. The overall on-site casting has good rigidity and is suitable for buildings with special requirements and high seismic requirements, but the template is expensive and the construction period is long. Prefabricated stair components are available in large, medium and small sizes. The large one is to pre-form the whole step and the platform into one component; the medium-sized one is to pre-form the step and the platform into one component, which is widely used; the small one is to pre-slope the inclined beam, step, platform beam and board Each small component is made and joined together by welding, anchor, bolt, pin, and the like. Another type of small is the prefabricated L-shaped step member, which is built into the side wall by the slope of the stairs and becomes a cantilevered staircase. The construction method of small prefabricated parts assembly is adaptable, easy to transport and install, and low in cost. For some on-site casting and partial prefabrication, the stair beam is usually molded first, then the prefabricated step and platform plates are installed, and then the steel bars are reserved in the three. The concrete is poured into the stairs and connected into a whole. This method saves the formwork and shortens the construction period compared to the overall on-site casting, but still maintains the precise characteristics of the prefabricated parts, and can be adjusted in size and form. Reinforced concrete stair steps require a surface that is easy to walk, wear resistant, non-slip, and easy to clean. The surface layer material is generally plastered with cement mortar, which can be used as terrazzo surface layer or with clinker bricks, marble veneers, even oil-filled carpets, plastic flooring materials and carpets. Steps near the step, you can use cement emery, mosaic, plastic, rubber and other anti-slip strips, or use a grooved ceramic or metal material to step on the mouth, and also play a protective role. 1. Types of cast-in-place concrete stairs 1 plate staircase The slab staircase is to treat the stair section as a sloping plate. The stair slab is divided into a platform beam and a platformless beam. 2 beam slab stairs 2. Detail construction of reinforced concrete stairs 1 step surface layer and anti-slip structure 2 railings and slab construction 3 railing and ladder connection 4 armrests The horizontal armrest end on the top platform should have a reliable connection to the wall. 5 foundation of the first stair section There are two basic methods for stair sections: one is to directly set the brick, stone and concrete foundation under the stair section; the other is to place the reinforced concrete ground beam on the stair wall and support the stair section on the ground beam.
