Description
Technical Field
The invention relates to the technical field of constructional engineering, in particular to a corrugated pane external wall structure of a cast-in-situ prestressed bare concrete overhead station and the overhead station, and particularly relates to a structural external wall structure design method for carrying out corrugated pane modeling and decoration by adopting integral cast-in-situ prestressed bare concrete for the overhead station.
Background
At present, the high-speed development of light rails and inter-urban rail transit is that the construction of overhead stations is more and more, and the overhead stations with various types become a bright landscape of the city. The design of the overhead station meets the functional requirements of the urban rail transit system and meets the requirements of urban planning, space environment, regional characteristics, humane amorous feelings and the like. In recent years, the construction technology of the bare concrete is rising, the cast-in-situ bare concrete is formed at one time, the surface is smooth and natural, the surface is not required to be modified on the appearance, the surface color is better, the three-dimensional effect is realized, the surface is smooth, the environment is not polluted, the bare concrete is natural and stable, and the bare concrete is graceful and heavy, which is compared with the existing method which is not adopted by some decoration materials, meets the modern aesthetic requirements, and is gorgeous and naive. As the bare concrete is formed at one time, plastering, coating, external hanging and other decorations are not needed, the generation of construction waste is greatly reduced, and the scientific development concept of building, environmental protection and energy saving in China is met. At present, the bare concrete outer wall is mostly used for externally hanging decoration, and the integral cast-in-situ reinforced bare concrete outer wall is adopted as a part of the structure to carry out irregular modeling, and the problem of bearing complex stress becomes a research problem. The construction of the cast-in-situ reinforced concrete outer wall adopts site reinforcement and concrete molding, which is very difficult to turn at any angle; in addition, the tensile strength and the compressive strength of the concrete are greatly different, and the concrete can bear larger compression but cannot bear tensile force, so that the cast-in-situ fresh water concrete outer wall is greatly limited in bearing irregular structural stress.
The design is needed to combine station platform layer canopy to design in the past, and most station canopy adopts steel construction, and structural style has portal, bow member, frame, truss, rack or membrane structure, and steel construction can satisfy various molding convenience, and design construction is easy, but this kind of structural style's canopy is thermal-insulated, heat preservation energy-conserving effect is relatively poor, because the station platform layer both ends of overhead are the train business turn over passageway, can not seal completely, and station air conditioning system also effect is extremely poor, and the south is hot summer, cold winter in north makes the station platform layer of overhead extremely difficult endure. In addition, the service life of the design of the rain shed in the form is 20 years, the service life of the design of the overhead station is 100 years, and the steel structure rain shed needs to be replaced and repaired in the station operation period, so that unnecessary waste and construction waste are brought. More elevated stations in recent years begin to adopt cast-in-place concrete roof structures, reinforced concrete roofs are good in heat insulation and heat preservation effect, but due to the requirements of lighting, ventilation and modeling, outer walls are mostly molded by glass curtain walls or light plates, and the heat insulation and heat preservation effect of the glass curtain wall structures is poor. The reinforced concrete outer wall is used for forming a relatively closed space, so that the heat insulation and heat preservation effects are good, the construction site pouring is not required, various building materials are not required to be purchased, and excessive external hanging is avoided, but the construction of the cast-in-situ reinforced concrete outer wall with a complex outer elevation modeling, such as corrugated modeling, windowing, hole punching and the like, is difficult, and the stress is unreasonable and is difficult to design and realize.
If the complex landscape modeling requirement of the outer wall with the reinforced concrete structure can be met, and the requirements of arbitrary modeling, ventilation and lighting of holes can be met, waiting at an elevated station platform is not so difficult to be decocted. Meanwhile, the mounting difficulty of excessive materials is avoided, and the repairment during the use period is not needed, so that the investment is saved, and the energy conservation and the environmental protection are realized.
