There are many kinds of steel structure industrial workshop buildings, including machinery plant, precision instrumentc factory building, aviation plant, shipyard, cement factory building, chemical factory, textile factory, thermal power factory, hydropower station building, nuclear power station building, etc.

Steel industrial workshop can be divided into production workshop, auxiliary production factory, warehouses, power stations and buildings for various purposes. Such as slide, chimney, hopper, water tower, etc. According to the production characteristics, it can be divided into hot processing factory building, cold processing factory and clean factory. The form of building space can be divided into single-layer steel structure workshop and multi-layer steel structure workshop.

Steel structure workshop has many advantages that reinforced concrete structure workshop does not have. Such as high strength, light weight, good overall stiffness, strong deformation capacity, large span, short construction period, fast construction speed, good wind and seismic resistance, environmental protection, energy conservation, consumption reduction, etc. However, due to the poor fire resistance and easy corrosion of steel, the steel structure industrial workshop also has the defects of non fire resistance and easy corrosion. These shortcomings also lead to higher maintenance costs in the later stage.

Any building structure has its advantages and disadvantages. Even if the steel construction workshop is not perfect, its advantages are just in line with the current development direction of building construction, and play a role in promoting the development of building industrialization.

What are the characteristics of steel structure industrial workshop?

• The steel industrial workshop has the advantages of light weight, high strength and large span.
• The construction period of steel structure workshop is short, and the investment cost is reduced accordingly.
• Steel structure buildings have high fire resistance and strong corrosion resistance.
• The steel structure industrial plant is easy to move and has no pollution for recycling.
• The steel industrial factory building has good building performance.

Seismic resistance

The roofs of low rise buildings are mostly inclined roofs, and the roof structure is a triangular roof truss system made of cold-formed steel members. The “plate rib structure system” has strong seismic and horizontal load resistance, and is suitable for areas with seismic intensity above 8 degrees.

Wind resistance

The steel structure building has the advantages of light weight, high strength, good overall stiffness and strong deformation capacity. The importance of the building is only one fifth of that of the brick concrete structure, which can resist the hurricane of 70 meters per second and effectively protect life and property.

Durability

The residential structure of light steel construction is composed of cold-formed thin-walled steel members. The steel frame adopts anti-corrosion high-strength cold-rolled galvanized sheet, which effectively avoids the impact of corrosion on steel. The service life of light steel components is increased during the construction and use of the plate. The service life of the structure can reach 100 years.

Comfort

The light steel wall adopts energy-saving system, which has breathing function and can adjust the dry humidity of indoor air. The roof has ventilation function, which can form a flowing air space above the house to ensure the ventilation and heat dissipation of the roof.

Heat insulation

Most of the thermal insulation materials used in steel structure workshops are mainly glass fiber cotton, with excellent thermal insulation effect. The use of thermal insulation board on the external wall can effectively avoid the “cold bridge” phenomenon of the wall and achieve better thermal insulation effect. The thermal resistance value of thermal insulation cotton with a thickness of about 100mm can be equivalent to the brick wall with a thickness of 1m.

Fast installation

All dry method construction is not affected by environmental seasons. The whole process from foundation to decoration of a building of about 300 square meters can be completed in 30 working days with only 5 workers.

Environment protection

Dry construction can reduce environmental pollution caused by waste. The steel structure materials of industrial plants can be recycled, and most other supporting materials can also be recycled, which is in line with the current awareness of environmental protection. All materials are green building materials, which meet the requirements of ecological environment and are beneficial to health.

Energy conservation

All adopt energy-saving walls, with good heat preservation, heat insulation and sound insulation effects, which can reach the 50% energy-saving standard.

Application of steel structure workshop

Large span industrial workshops, hardware, plastics, mechanical equipment, printing paper products, molds, machinery manufacturing, chemical industry and other industries. There are also warehouses, cold storages, high-rise buildings, office buildings, multi-storey parking lots, residential buildings and other construction industries. Steel structure buildings are also widely used in hotels, gymnasiums, large markets, leisure resorts and so on.

Architectural design of steel industrial workshop

The following points must be achieved in the design of industrial workshop:

• Good daylighting. Generally, natural lighting is used in workshops, but the uniformity of lighting is poor. For example, the worsted and weaving workshops of textile factories mostly adopt natural lighting, but direct sunlight should be solved. If the natural lighting cannot meet the process requirements, artificial lighting shall be used.
• Good ventilation. If natural ventilation is adopted, it is necessary to understand the internal conditions of the workshop, such as heat dissipation, heat source conditions, local meteorological conditions, exhaust channel design, etc. Some heat treatment and dust workshops that emit a large amount of waste heat, such as casting workshops, should pay attention to natural ventilation.
• The shape of buildings emitting corrosive gas and dust shall be simple. In order to maintain good natural ventilation, it can use buildings with only roofs but no wallboards.
• For walls and roof slabs, the corrosion of buildings caused by the condensation and condensation of corrosive gases on the walls and roofs shall be reduced according to the indoor temperature. Corrugated metal plates are commonly used as roofing and wall materials for steel industrial plants. Glass wool or sandwich panels are laid on the walls and roofs of factory with thermal insulation requirements.

Corrosion prevention of steel industrial factory building

The use and production of acids, alkalis, salts and corrosive solvents in industrial processes. Corrosive media in atmosphere, groundwater, surface water and soil can cause corrosion of buildings.

Galvanized steel structure

Hot galvanizing can be used as the anti-corrosion method for steel structure industrial workshops. Hot dip galvanizing is to immerse the derusted steel members into the high-temperature zinc solution at about 600 ℃, so that a layer of zinc layer is attached to the surface of the steel members to prevent corrosion. Hot dip galvanized steel sheet has long durability, so it is widely used in outdoor steel structures which are seriously corroded by the atmosphere and difficult to repair.

Painting of steel structure

Industrial steel structure workshop can also be treated with paint for corrosion prevention. The paint is generally divided into primer, intermediate paint and finish paint. Different coatings have different corrosion resistance. High quality coating shall be selected for steel structure plant to ensure its anti-corrosion performance and improve the corrosion resistance of steel structure factroy building.
