Buildings directly used for production or supporting production
Industrial plants refer to various houses directly used for production or supporting production, including main workshops, auxiliary rooms and auxiliary facilities.Where industryTransportationFactories in commercial, construction, scientific research, schools and other units should be included.In addition to the workshops used for production, industrial plants also includeAncillary building。
Industrial plant, as its name implies, is used for industryProduction processHouse in.In addition to the workshop used for production, the industrial plant also includes its auxiliary buildings, such as power distribution room, water supply room, sewage discharge, equipment and materials storage and other supporting buildings, which belong to the category of industrial plant or part of industrial plant.
2. Factories owned by enterprises in the development zone, including foreign-funded enterprises andenterprise with domestic fundingPart or all of the factory buildings in a development zone also include the factory buildings of companies specialized in building and leasing factory buildings in a development zone.
2. Factory buildings without property rights (usually not caused by the land property right certificate, which includes two kinds of punishment, namely, having accepted the punishment of illegal construction and not having accepted the punishment of illegal construction).
（3） According to the plant structure and supporting classification:
Single layer/multi-layer, with or without driving, power distribution, water supply and sewage discharge.
（4） According to the production characteristics of products, industrial plants can be roughly divided into the following three types.
2. Explosion and fire hazard production plant: normal productionElectronic radiatorOr stored with explosion and fireDangerous goodsPlant of.
3. Production plants in harsh environment: production plants with dust, humidity, high temperature or steam, vibration, smoke, acid and alkali corrosive gases or substances, and radioactive substances.
The majority of factories in multi-storey industrial buildings are found in light industry, electronics, instrumentation, communications, medicine and other industries. The floors of such factories are generally not very highlighting design It is similar to the common scientific research laboratory buildings, and is mostly usedFluorescent lampLighting scheme.The production plants in machining, metallurgy, textile and other industries are generally single storey industrial buildings, and according to the production needs, more are multi span single storey industrial plants, that is, adjacent to the multi span plants arranged in parallel, each span can be the same or different as required.
Single storey workshopWhen meeting certain requirementsBuilding moduleThe building width (span), length and height shall be determined based on the requirements according to the process needs.The span B of the powerhouse is generally 6, 9, 12, 15, 18, 21, 24, 27, 30, 36 m.The length of the factory building L: tens of meters at least, hundreds of meters at most.The height of the plant H: generally 5-6m for the low, 30-40m for the high, or even higher.The span and height of the workshop are the main factors considered in the lighting design of the workshop.
In addition, according toindustrial production ContinuityAnd product transportation between sections. Most industrial plants are equipped with cranesLifting capacityThe light ones can be 3~5t, and the large ones can reach hundreds of tons（Machinery industryThe maximum lifting capacity of a single crane can reach 800t).Therefore, factory lighting is usually realized by lamps installed on roof truss.

The design standard of industrial plant is formulated according to the plant structure, and the plant design is based ontechnological processandProduction conditionsThe design is carried out only when the form of the workshop is determined.
Standard plant design code
1、 The design of industrial plants must implement the relevant national guidelines and policies, achieve advanced technology, economic rationality, safety and applicability, ensure quality, and comply withenergy conservationAnd environmental protection requirements.
2、 This specification is applicable to the design of newly-built, reconstructed and expanded industrial plants, but it is not applicable to bacteriacontrol object OfBiological clean room。This specification relates to fire prevention and evacuationFire fighting facilitiesThe provisions of the chapter are not applicable toBuilding heightDesign of high-rise industrial plants and underground industrial plants more than 24 meters long.
3、 Article When the original building is used for clean technology transformation, the industrial plant design must be based on the productiontechnological requirements, adjust measures to local conditions, treat differently, and make full use of existing technical facilities.
4、 The industrial plant design shall create necessary conditions for construction, installation, maintenance management, testing and safe operation.
5、 In addition to this specification, the design of industrial plants shall also comply with the currentnational standardRelevant requirements of the specification.
6、 The industrial plant is composed of an independent building (workshop) and an independent building (dormitory). The distance between the two buildings is 10 meters, and the nearest one shall not be less than 5 meters, so as to pass the fire acceptance.The ratio of floor area to building area is 1:3.
To makeSteel structure workshopThis standard is formulated to standardize and serialize the geometric dimensions of the main components and parts of the building to facilitate industrial production.
2、 Preparation of plant building componentsStandard designAtlas.
Note: ① Some provisions of this standard may not be implemented in the design of steel structure plants, reconstruction (expansion) plants subject to conditions, cast-in-place reinforced concrete structure plants, plants with special process requirements for plants, or plants designed according to this standard that will cause significant unreasonable technically and economically; ②The plant with new technology, new structure and new materials may not be restricted by some provisions of this standard.
On the basis of reasonable technology and economy, the shape of the plant should be as simple as possible, and the vertical and horizontal span and multi span plant should be avoidedHeight difference。
When preparing the standard design atlas of factory building components and fittings, components and fittings with the same purpose shall be used to maximize theInterchangeability。
workshopArchitectural designIn addition to the relevant provisions of this standard, it shall also comply with the provisions of the current relevant national standards.
