Steel Frame—Ribbed column Box System, or RCB system for short: Working principle of the system is to connect steel beams and columns by high strength bolts to form ribbed column rigid wall and to enhance rigidity by fastening rod on the end, then all rigid walls combined further by wall connection to form a more stable box system.
Variety of structural steel can be combined according to the building span and tolerance changes through the computer-aided design, the amount of steel can be gradually reduced as the combinations increase. Unit shear wall is a unit of the structural system, and the load of the building can be evenly distributed and transmitted reasonably and effectively to avoid localized stress. The system is Japanese current mainstream residential construction technology. There can be diversified designs with light steel structure design software.
The advantages of RCB system are as below:
1.Anti-seismic & wind resistant
Unique box structure can make building as a whole unit with high seismic performance. It can meet the 8 degree seismic requirements.
The house is integrally connected to the foundation, so that it is with high wind-resistant performance, and can withstand strong wind (maximum 40m / s).
2.Refactory & Weathering
The whole house steel structure is surrounded by the inorganic material ALC panel, it is a incombustible material, and can reach A grade fireproof requirement;
ALC panel and seamless body structure can form a fully enclosed space and effectively resist the cold , or hot weather;
3.Waterproof & Anti-rust
Full-enclosed waterproof system: to take multiple structural measures at key parts to prevent leakage risks;
More than 80% of the components use galvanized materials, to avoid oxidation and rust, the rational use of life is more than 50 years;
4.Energy-saving &Environmentally friendly
Thermal conductivity of ALC panel is 0.13W/(m.k), unique hollow structure approach is 30% better than the traditional structure in thermal insulation performance.
Dry construction and no construction waste can ensure the green environment. All materials can be recycled and removable for off-site reconstruction.
5.Comfortable &low carbon
High sound insulation performance (80 decibels outdoor, 40 decibels indoor), no radioactivity (exposure 12γμ / h).
High air tightness and heat insulation to reduce energy consumption and carbon dioxide emissions, and to enhance the living environment.
6.Industrialization, and sustainable development
Design specialization, production automation and installation standardization can form a complete industrial line;
As a green building practitioner, in line with national policies to promote the industrialization, we support sustainable development of residential undertakings.
