Technical Field
The invention relates to the field of transformer substation building design, in particular to a transformer substation building structure built by prefabricated parts.
Background
The prefabricated member refers to a steel, wood or concrete member previously manufactured in a factory or on the site according to design specifications. The prefabricated members are various, and concrete members are common. The fabricated building is a building which is formed by transferring a large amount of field operation work in the traditional construction mode to a factory, processing and manufacturing building components and accessories (such as floor slabs, wall slabs, stairs, balconies and the like) in the factory, transporting the components and accessories to a building construction site, and assembling and installing the components and the accessories on the site in a reliable connection mode. The prefabricated building mainly comprises a prefabricated concrete structure, a steel structure, a modern wood structure building and the like, and is a representative of a modern industrial production mode due to the adoption of standardized design, factory production, assembly construction, informatization management and intelligent application.
In China, the application of concrete prefabricated parts in the municipal road and bridge industry is very wide and mature, but the application starts later in the building industry. The technical application of the building prefabricated part is that the building prefabricated part is applied after the proposition of the 'housing industrialization' proposition of the housing department, and in the last two years, part of real estate enterprises begin to research the housing industrialization of the building prefabricated part and develop high-end buildings. In some big cities, there have been some attempts to adopt a prefabricated construction method for public buildings such as multi-story office buildings. Adopt assembled structural component in building engineering, the industrialization degree is high, and the assembly is simple, and construction convenience is efficient. The rapid development of the fabricated building is also a policy of national and local key support and popularization. However, the application of the assembly type building is less in the power transformation project at present, and the assembly type structural member is rarely applied to the domestic power transformation project. In order to make the prefabricated building be better applied to the transformer substation, it is urgently needed to perform large adjustment and optimization on the structural arrangement of the transformer substation, and perform some optimization adjustment on a prefabricated structural product so as to be more suitable for use.
CN207063610U discloses a transformer substation building structure by prefabricated component concatenation, discloses prefabricated post, prefabricated floor, prefabricated interior wallboard, prefabricated exterior wallboard, prefabricated cable shaft, has solved the stable problem of concatenation formula building in the transformer substation.
The transformer substation generally has indoor transformer substation, outdoor transformer substation and semi-open transformer substation, no matter which kind of transformer substation type, the used bottom plate of main transformer basis and the oil pit basis in the transformer substation all designs alone, does not form an integral stress structure, because the atress inequality or the upper portion load difference of both foundations are great, cause the differential settlement between them, produce great crack between oil pit and the main transformer basis, when there is the greasy dirt in the oil pit, often can permeate the underlying soil through crack between the two, cause and environmental pollution. In addition, an oil pit is not connected with a building foundation, so that the settlement difference between the main transformer oil pit and the building is large, the 10kV tubular bus is easy to deform under stress, and the potential safety hazard of electrical equipment is caused. The problem is not solved to above-mentioned patent, if design into holistic prefabricated atress bottom plate with main transformer basis and oil pit basis exclusive use, can further optimize the transformer substation structure, improves the efficiency and the quality of building of transformer substation.
