Steel structure workshop mainly refers to the main load-bearing components are made of steel. Including steel pillars, steel beams, steel structure foundations, steel roof trusses, steel roofs, note that steel structure walls can also be maintained by brick walls. Due to the increase in steel production in China, many steel structure workshops have begun to be adopted. Specifically, it can be divided into light and heavy steel structure workshops. Industrial and civil construction facilities constructed of steel are called steel structures.
The characteristics of the steel structure workshop are as follows: 1. The steel structure is light in weight, high in strength and large in span. 2. The construction period of steel structure buildings is short, which reduces investment costs accordingly. 3. Steel structure buildings have poor fire resistance and corrosion resistance, and steel structures should not be used in areas with low temperature. 4. The steel structure building is easy to move, and the recycling is pollution-free.
Shock resistance
The roofs of low-rise villas are mostly sloping roofs, so the roof structure basically uses a triangular roof truss system made of cold-formed steel components. The light steel components form a very strong structure after sealing the structural plates and gypsum boards." "Slab-rib structure system", this kind of structure system has stronger seismic resistance and resistance to horizontal load, and is suitable for areas with seismic intensity above 8 degrees.
Wind resistance
The profiled steel structure building has light weight, high strength, good overall rigidity and strong deformability. The weight of the building is only one-fifth of the brick-concrete structure, and it can withstand a hurricane of 70 meters per second, so that life and property can be effectively protected.
Durability
The light steel structure residential structure is all composed of cold-formed thin-walled steel component system. The steel frame is made of super anti-corrosion high-strength cold-rolled galvanized sheet, which effectively avoids the influence of steel plate corrosion during construction and use, and increases the service life of light steel components. The structural life can reach 100 years.
Heat preservation
The heat preservation and heat insulation materials used are mainly glass fiber cotton, which has good heat preservation and heat insulation effect. The use of thermal insulation boards on the outer wall effectively avoids the "cold bridge" phenomenon of the wall and achieves a better thermal insulation effect. The thermal resistance of R15 insulation wool with a thickness of about 100mm can be equivalent to that of a brick wall with a thickness of 1m.
Sound insulation
The sound insulation effect is an important indicator to evaluate the residence. The windows installed in the light steel system are made of hollow glass, which has good sound insulation effect, and the sound insulation can reach more than 40 decibels. The wall composed of light steel keel and thermal insulation material gypsum board has a sound insulation effect of 60 decibels.
Health
Dry construction can reduce environmental pollution caused by waste. The steel structure of the house can be recycled, and most of the other supporting materials can also be recycled, which is in line with current environmental protection awareness; all materials are green building materials, which meet the requirements of the ecological environment and are beneficial to health.
Comfort
The light steel wall adopts a high-efficiency and energy-saving system with a breathing function that can adjust the dry humidity of the indoor air; the roof has a ventilation function, which can form a flowing air space above the house to ensure the ventilation and heat dissipation requirements inside the roof.
Quick
All dry work construction, not affected by the environmental season. For a building of about 300 square meters, only 5 workers and 30 working days can complete the whole process from foundation to decoration.
Environmental friendly
The material is recyclable, and it is truly green and pollution-free.
Energy saving
All use high-efficiency energy-saving walls, which have good heat preservation, heat insulation and sound insulation effects, and can reach the energy-saving standard of 50%.
advantage
1 Wide range of uses: applicable to factories, warehouses, office buildings, stadiums, hangars, etc. It is not only suitable for single-story large-span buildings, but also for the construction of multi-story or high-rise buildings.
2 Simple construction and short construction period: All components are prefabricated in the factory, and the site only needs to be assembled simply, thus greatly shortening the construction period. For a building of 6000 square meters, the basic installation can be completed in only 40 days.
3 Durable and easy to maintain: The steel structure designed by general-purpose computers can withstand harsh weather and requires simple maintenance.
4 Beautiful and practical: the lines of the steel structure building are simple and smooth, with a modern sense. The color wall panels are available in a variety of colors, and the walls can also be made of other materials, so they are more flexible.
5 Reasonable cost: The steel structure building is light in weight, reducing the basic cost, and the construction speed is fast. It can be completed and put into operation as soon as possible, and the overall economic benefits are much better than that of the concrete structure building.
