The factory construction of green and low-carbon buildings in Yuanda represents the advanced production level of the construction industry and is a revolution to the traditional construction industry.
First, solve three major quality problems.
1. Waterproofing and impermeability: Yuanda residents always pay attention to the consumption of resources and energy in the process of construction and operation, adopt simple standard product design, reduce the wall-to-ground ratio, and use high-grade insulating glass heat and sound insulation windows combined with components to shade the sun, saving materials and energy.
2. Thermal insulation: The thermal insulation system with full broken bridge and fireproof interlayer is effective, reliable, durable, energy-saving and comfortable, ensuring life safety at critical moments.
3. Improve the accuracy: Yuanda residents use large-scale factory assembly lines to produce prefabricated components, and the processing accuracy and quality are unmatched by on-site operation. The construction error increases by an order of magnitude from centimeter to millimeter, and the ceiling wall is dense and flat.
Second, to achieve three controllable
1, controllable quality: solving three quality problems: waterproof and impermeability, thermal insulation and improving accuracy.
2. controllable cost: provide complete technical service support from the design stage, and the accurate and transparent budget cost of main construction and decoration construction provides reliable reference for your decision-making; The traditional construction period of Yuanda Comprehensive Building is about 1/3, and 7-8 people can build one building, so the comprehensive cost of the building is obviously controllable.
3. The progress is controllable: for the PC hoisting and cast-in-place parts, the high-rise building has a floor for about 5 days (including partition walls) and the multi-storey building has a floor for about 2 days, which is less affected by the weather.
Third, realize five major changes.
Yuanda Fifth Generation Integrated House (BH5) is the latest product of Yuanda, which fully absorbs the advanced concepts and technologies of the United States, Japan and Singapore after more than ten years of exploration, and integrates a number of patents and core technologies on the basis of the first, second, third and fourth generation integrated houses.
① Safe and durable
Vertical load-bearing structural systems such as columns and shear walls all adopt cast-in-place method; The beam of the horizontal structure system and the enclosure structure system below it adopt integral precast reinforced concrete to form a precast wall with composite functions, which has good safety and reliability.
② Energy saving and heat preservation
Composite prefabricated wall, thick insulation layer and double-layer insulating glass improve insulation performance, which is warm in winter and cool in summer.
③ Waterproof and impermeability
Seamless connection, put an end to external wall water seepage. The window frame is embedded in the PC wall, which fundamentally solves the problem of window leakage; The integral bathroom chassis is integrally formed at one time and never leaks.
④ Low carbon and environmental protection
The main structure adopts PC, so the whole building does not need bricks, there is no loss of construction waste and materials, it does not destroy the natural environment and reduces exhaust emissions. The finished room is made of environmentally friendly materials, and there is no disturbance caused by secondary decoration.
