楼梯结构简明构造（Simple structure of stairs structure） The ladder on the oblique beam embedding stirrup, and the tread plate supporting end reserved hole plug, with high grade cement mortar filling. (2) ladder beam or boards of the ladder platform beam connection In addition to the use of cement mortar slurry at the base, should be buried at the end of the welded steel plate welding. (3) ladder beam or boards of the ladder platform beam connection At the bottom of the stairs at the start, ladder beam or board of the ladder should be under the ladder ladder base base, common brick or concrete, can also be used instead of ladder platform beam base. But attention should be paid to the relation between the platform of the platform beam and the terrace. Two, wall supported Prefabricated prefabricated wall reinforced concrete staircases are precast concrete reinforced concrete steps that are placed directly on the wall of a staircase. The step board generally adopts a shape, L shape or grosseserrata section. Prefabricated wall bearing reinforced concrete stairs because both ends of the stairs were wall support, without a ladder platform beam and beam, also do not need to install railings to set against the wall handrail, saving steel and concrete. But because each step board is directly installed into the wall, it has great influence on the wall masonry and construction speed. At the same time, the shape and size of the step board into the wall are not easy to match with the module number of the wall block, so the quality of the masonry is not easy to guarantee, and the strength of the masonry is affected. This staircase, because there is a wall between the ladder, furniture is not easy to move, but also block the line of sight, on the flow of people easily collide. Usually in the middle wall set observation port, so that the flow of people up and down the line of sight. The middle wall can be partly closed by the platform part so as to make the space transparent, and can improve
