Concrete Encased Steel Beam
Concrete encased steel beam have more advantages than traditional brick buildings:
Sound insulation: sound insulation effect is an important indicator to evaluate the residence, the windows installed in the light steel system are made of insulating glass, the sound insulation effect is good, and the sound insulation is more than 40 decibels; The sound insulation effect of the wall composed of light steel keel and thermal insulation material gypsum panels can be as high as 60 decibels.
Health: housing braced frame structure steel structure materials can be 100% recycled, other supporting materials can also be mostly recycled, in line with the current environmental awareness; All the materials are green building materials, which meet the requirements of ecological environment, reduce the pollution caused by waste to the environment, and are conducive to health.
Comfort: the light steel wall adopts high-efficiency and energy-saving system, has breathing function, and can adjust the dry humidity of indoor air; The roof has a ventilation function, which can form a flowing air room above the house to ensure the ventilation and heat dissipation needs inside the roof
Fast: all dry operation construction, not affected by the environmental season. For a building of about 300 square meters, only five workers can complete the whole process from foundation to decoration in 30 working days.
Environmental protection: materials can be 100% recycled, truly green and pollution-free
Good plasticity and toughness of steel: good plasticity, so that the concrete encased steel beam will generally not be suddenly fractured and damaged due to accidental overload or local overload. Good toughness makes the steel structure more adaptable to dynamic loads. These properties of steel provide a sufficient guarantee for the safety and reliability of steel structures.
Steel is closer to homogeneous and isotropic: the internal structure of steel is relatively uniform, very close to homogeneous and isotropic, and almost completely elastic within a certain stress amplitude. These properties and the assumptions in the mechanical calculation are more consistent, so the calculation results of the steel structure are more in line with the actual force situation.
The steel structure is simple to manufacture, easy to use industrial production, and the construction and installation period is short: the steel structure is composed of various profiles, and the production is simple. A large number of steel structures are manufactured in specialized metal structure manufacturing plants; High accuracy. The components made are transported to the site for assembly, bolted connection, and the structure is light, so the construction is convenient and the construction period is short. In addition, the completed steel structure is also easy to disassemble, reinforce or modify.
steel structure residential buildings than traditional buildings can better meet the requirements of large room flexible separation, and can reduce the column section and the use of light wall panels, improve the utilization of area, indoor effective use area increased by about 6%.
Good energy-saving effect, the wall adopts light energy-saving standardized prefabricated wall panels instead of clay bricks, good thermal insulation performance, energy saving of 50%, and can save 18 yuan per square meter of heating and cooling costs per household.
The steel structure system used in residential buildings can give full play to the steel structure of good ductility, plastic deformation ability, excellent seismic and wind resistance performance, greatly improve the safety and reliability of housing. Especially in the case of earthquake and typhoon disaster, it can avoid the collapse of buildings. For example, the earthquake in Japan in 95 years, 99 years Taiwan earthquake did not collapse almost all of the H-beam steel made steel structure buildings.
The total weight of the building is light, steel structure residential system light weight, about half of the concrete structure, can greatly reduce the foundation cost.
The construction speed is fast, the construction period is at least 1/3 shorter than the traditional housing system, so it can reduce the comprehensive cost, the comprehensive cost is reduced by 5%. Speed up the capital turnover, greatly improve the investment efficiency.
Good environmental protection effect. The construction of steel structure residential buildings greatly reduces the amount of sand, stone and ash, and the materials used are mainly green materials, recyclable or degradable materials. When the building is dismantled, most of the materials can be recycled or degraded without causing a lot of garbage.
It has a high performance-price ratio.
The architectural style is flexible and abundant. Large room design, indoor space can be divided by multiple schemes, to meet the different needs of users.
Meet the requirements of residential industrialization and sustainable development.The steel structure is suitable for large-scale production of factories, with a high degree of industrialization, and can integrate advanced finished products such as energy saving, waterproofing, heat insulation, doors and windows, and complete sets of applications, integrating design, production and construction, and improving the level of the residential industry.
