Steel structure engineering advantage project: steel structure engineering scope: residential building, real estate development, large cities with limited land area, industrial and commercial and civil buildings. It is widely used.
Steel structure engineering design: portal steel structure, H-beam frame, composite frame steel. Steel structure floor design: steel structure engineering floor is usually used for rolling floor steel plate, that is, cast reinforced concrete floor, the thickness of the floor is generally not less than 150 mm. If the steel beam and steel-concrete composite slab are used together, it is called MST composite beam. As long as the calculation is correct, the reinforcement is reasonable, and the studs are reliable, using steel plate as floor and roof steel beam can save 20% of the cost, but it is not necessary. Check the stability of the steel beam. Compared with the concrete building, the construction time is greatly saved, and the construction is not affected by the season;
The basic design method of steel structure engineering: higher foundation requirements, base thickness of 1.5m to 3m, combined with ground beam complementary.
The indoor layout of steel structure engineering is flexible and the price is high. The inner wall partition is used for indoor layout with small bearing capacity (such as large open space, evacuation, retreat, stratification, etc.), its thickness is about 1 / 2 of the traditional structure, and the internal use area increases. More than 10%, the house price is as high as 92%; The slab has no main beam, and the floor height is increased by more than 200 mm. Expand the use area of residential space, reduce construction waste and environmental pollution; Building materials can be recycled, and steel structure is used as raw materials to drive the development of domestic real estate, building materials and hardware industries; The steel structure project adopts composite wall and floor, and various intelligent technical equipment such as equipment, pipeline, anti-theft, intercom system and fresh air ventilation can be perfectly combined with shell products. Its anti-seismic performance is good, easy to refit in use, flexible and convenient, giving people comfort and other advantages.
Advantages of steel structure engineering: steel structure engineering is 30% - 50% lighter than reinforced concrete structure, and the section of steel structure is small, the wall thickness is about 1 / 2 of the traditional structure, and the internal use area increases by more than 10%. House prices reached 92%. The shape is novel and beautiful, which fully embodies the characteristics of steel structure and modern architecture. Comprehensive life of steel structure engineering: 70 ~ 100 years.
