The stairs are small buildings in the building. They are relatively small in size and relatively simple in structure. These factors have relatively limited restrictions on the shape of the stairs. In the creation, the architect can design the stairs as a kind of space decoration, and can surpass the pure function and fully exert his imagination while satisfying its function. When designing the stairs, the relationship between the stairs itself and the space around it must be considered, that is, the two factors of the inside and outside of the stairs. The interior refers to the structure and construction of the staircase itself, the choice of materials, the steps of the stairs and the handling of the railings; and the exterior refers to the characteristics of the space around it. Only when the two are considered together can they be perfectly combined. In many public buildings today, stairs are often a focal point of architectural design, which serves as a space for space, and space provides a stage to show the aesthetics of the stairs.
In the atrium space of the hall
The atrium space of a public building is generally a two-story space that is closely connected to the entrance hall, while other functional spaces are arranged along it or the cloister, or along one side. It can be said that the atrium space is designed as a key space, and generally forms an open and bright space with the floor glass or glass roof of the entrance façade. Stairs are designed in this well-lit space and are generally designed according to the plane relationship. Some are in the center of the atrium, some along the side of the atrium; and the stairs are arranged in a plane with the atrium, either parallel or perpendicular to one side. Generally, the stair design is relatively light and clear, the tread plate has only a horizontal plane, and the stair material is determined according to the characteristics of the building space. Various forms of stairs such as straight lines, broken lines and curved shapes can be used here. The style of the stairs is due to its spatial relationship, traffic flow and
The spatial characteristics of the stair building are determined. People here are not only completing walking up and down in the vertical space, but also becoming the center of sight of people. On the one hand, from the ground floor of the atrium space, people can look up when they step on the stairs, and on the other hand, they can look down on the second floor of the atrium space against the railing of the cloister.
The stairs also serve to enrich the spatial hierarchy and make the space continuous. In the shape of the stairs, different configurations, or echoes, or contrast spaces can be used. If it is a double-fold staircase, the relationship between the rest platform and the atrium space is particularly important. If the lobby space is relatively closed, the solid wall is the main one. When the ladder is arranged along the side of the wall, the importance of the space above the stairs is often emphasized and plays a guiding role. The stair design contrasts with the surrounding enclosed space, giving the relatively dull space a bright spot.
Especially in the relatively large atrium space, the stairs may become the protagonist of space to organize traffic and form the overall shape of the atrium space. The city hall of Marseille, France, the grand atrium space, the arrangement of stairs and rolling escalators in different directions and different plane positions enrich the relatively empty atrium, and the shape of the straight staircase forms a certain geometric relationship with other building components. In the hall of a gymnasium in France, several two-fold stairs are arranged side by side, one to meet the function of the stadium itself to evacuate people as soon as possible, and the other to connect the stands on different floors. Its main form of lines makes the relatively narrow and tall space no longer dull. From the above two examples, it can be explained that a good stair design can make up for some aspects of the original space.
In the atrium space, every part of the stairs needs to be carefully considered and designed. In three-dimensional space, the staircase is like a space sculpture. Its steps, bottoms, stair beams, railings, and handrails can all be modeling elements, and their materials and colors must also be considered at the same time. Only in this way can we achieve extraordinary results. .
