Explanation! The steel Structural engineering you want to know

Steel Structural engineering project

The steel Structural engineering project is a structure dominated by stainless steel plate manufacturing, and the key is composed of steel columns, steel beams, steel pipe trusses and other components made of channel steel and thick steel plates. Each component or component is generally connected by welding, anchor bolts or rivets, which is one of the key types of engineering construction structures. Due to its relatively light weight and simple engineering construction, it is widely used in industries such as large and medium-sized industrial factories, exhibition halls, and high-rise residential buildings.

Steel structure characteristics

⊙ The steel structure itself has a relatively light weight

⊙ High reliability in steel structure operations

The durability and impact resistance of stainless steel plates are good

⊙ Steel structure can be installed accurately and quickly

⊙ High degree of modernization in steel structure production and manufacturing

⊙ Large steel structure indoor space design

⊙ It is very easy to make a sealing structure

Development History

Although there were extraordinary achievements in the early stages of steel structure construction in our country, due to the constraints of feudal society for over 2000 years, scientific research was not carried out, resulting in long-term stagnation at the level of iron construction. It was not until the late 19th century that intelligent steel structures were first adopted in China. After the establishment of the People's Republic of China, the application of steel structures has shown a significant trend, surpassing the past in terms of both total quantity and quality. We have achieved a high level in the design scheme, production, manufacturing and installation and other technical aspects. We have mastered a variety of design schemes and construction techniques for miscellaneous construction. We have already built many steel structure industrial plants, large-span steel structure industrial buildings and railway tunnels with large business scale and miscellaneous structures in various provinces of China, The spherical grid structure of sports venues in Shanghai and Beijing, the three hinge steel arch structure of the Shaanxi Provincial First Emperor General and Mercenary Exhibition Hall, and the Beijing Bird's Nest in Beijing.

9 major features

one

Durability: Most of the flat roofs of low rise villas are sloping roofs, so the flat roof structure mostly adopts a triangular steel roof truss system made of cold-drawn steel components. Light steel structural components produce a very sturdy "plate rib structure system" after sealing the structural board and paper gypsum board. This type of structural system has stronger seismic resistance and ability to withstand horizontal loads, Suitable for areas with seismic resistance levels above 9 degrees.

two

Wind resistance: structural steel Structural engineering has light construction component, high compressive strength, good overall stiffness, and strong anti deformation ability. The weight of building itself is only one-fifth of that of a brick concrete structure, which can withstand storms of 70 meters per second and provide reasonable maintenance for personal safety.

three

Usage performance: The residential structure of light steel structure is composed of a cold drawn thick walled steel component system, and the anchor is manufactured using highly corrosion-resistant high-strength cold-rolled galvanized steel plate, which reasonably avoids the harm of rust caused by thick steel plates during the entire construction and use process, and improves the service life of light steel structural components. The service life of the structure reaches 100 years.

four

Thermal insulation: The raw materials used for thermal insulation are mainly glass fiber cotton, which has excellent practical effects on thermal insulation. The thermal insulation board used for walls effectively avoids the "hot bridge" situation on the wall, achieving a stronger practical effect of thermal insulation. The thermal resistance value of R15 insulation material with a thickness of 100 millimeters can be equivalent to that of a wall with a thickness of 1 meter.

five

Thermal insulation: The actual effect of sound insulation and noise reduction is a key indicator value for evaluating residential properties. The windows installed in the light steel structure system all use hollow glass windows, which have excellent sound insulation and noise reduction effects, with sound insulation and noise reduction reaching over 40 decibels; The wall composed of light steel keel partition and insulation material paper gypsum board has a practical sound insulation and noise reduction effect of up to 60 decibels.

six

Physical and mental health: dry construction projects can reduce environmental pollution caused by waste materials to the natural environment. 100% of the steel structure raw materials of houses can be purchased, and the majority of other supporting facilities raw materials can also be purchased, which is in line with today's protection awareness; All raw materials are green construction, taking into account ecological and environmental protection regulations, which is beneficial for physical and mental health.

seven

Comfort: The lightweight steel structure wall adopts an efficient environmental protection and energy-saving system, which has a suction effect and can adjust the dryness of indoor air quality; The roof has a natural ventilation function, which can generate a flowing gas chamber in the air inside the house, ensuring the natural ventilation and heat removal requirements inside the roof.

eight

Fastness: All dry work projects will not be affected by natural environmental hazards during construction. The construction of a 300 square meter building requires only five employees to complete the entire process from roadbed to interior decoration within 30 working days.

nine

Green and environmentally friendly: All walls adopt high-efficiency, environmentally friendly, and energy-saving walls, which have excellent insulation, sound insulation, and noise reduction effects, and can achieve 50% of the environmental and energy-saving standards. The raw materials can be 100% purchased, truly ensuring green and zero pollution.
