A substation construction structure built with prefabricated components

Abstract

The invention relates to the field of substation building design, more specifically, to a substation construction structure constructed with prefabricated components. Including the main transformer oil pit area, grounding transformer equipment area, and underground wiring area. The main transformer oil pit area is equipped with the main transformer foundation and the main transformer oil pit foundation. The main transformer oil pit foundation and the main transformer foundation are supported by the first prefabricated bottom plate The aboveground part of the substation equipment area and the underground wiring area is supported by the second prefabricated floor, and the underground wiring area is supported by the third prefabricated floor. The first prefabricated floor, the second prefabricated floor and the third prefabricated floor are provided with structural columns and The gaps connected by the structural beams, the first prefabricated bottom plate, the second prefabricated bottom plate and the third prefabricated bottom plate are connected on different horizontal planes of the structural columns to form an overall force-bearing structure and improve the construction efficiency and quality of the substation building.

Description

technical field [0001] The invention relates to the field of substation building design, more specifically, to a substation construction structure constructed with prefabricated components. Background technique [0002] Prefabricated elements refer to steel, wood or concrete elements prefabricated in factory or on site according to design specifications. There are many kinds of prefabricated components, the common ones are concrete components. Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and transported to the construction site. Reliable connections are assembled and installed on site. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc., because of the use of...

Problems solved by technology

[0004] CN207063610U discloses a substation building structure spliced ​​by prefabricated components, discloses prefabricated columns, prefabricated floor slabs, prefabricated inner wall panels, prefabricated outer wall panels, prefabricated cable shafts, and solves the stability problem of spliced ​​buildings in substations

[0005] Substations generally include indoor substations, outdoor substations and semi-open substations. Regardless of the type of substation, the base plates used for the main transformer foundation and oil pit foundation in the substation are mostly designed separately, and do not form an overall force-bearing structure. Due to the two The uneven stress of the foundation or the large difference in the upper load will cause uneven settlement of the two, and large cracks will form between the oil pit and the main transformer foundation. When there is oil in the oil pit, it will often pass through the gap between the two The cracks seep into the soil below, causing and environmental pollution

In addition, there is no connection between the oil pit and the building foundation, resulting in a large settlement difference between the main transformer oil pit and the building, making the 10kV pipe bus easily deformed by force, causing safety hazards for electrical equipment

The above-mentioned patent does not solve this problem. If the base plate used separately for the main transformer foundation and the oil pit foundation is designed as an integral prefabricated force-bearing base plate, the structure of the substation can be further optimized, and the construction efficiency and quality of the substation building can be improved.
