The balance of technology, design and green has become the key to design.

In this project, architectural design is no longer just pure rational thinking or pure perceptual output.

At the beginning of the design, sea selected the “Timoshenko” technology – implicit frame steel structure residential system, which is formed by wide concrete-filled steel tubular columns and narrow flange H-shaped steel beams.

This structural system not only meets the needs of building industrialization and ecological civilization, but also meets the flexible layout of buildings because the steel columns and beams are small in size and easy to be hidden in the building wall.

The portal, steel beam, wallboard, elevator shaft and other areas have been treated with different degrees of fire prevention, crack prevention, sound insulation and waterproof.

In the process of on-site construction, the above ground steel columns are installed on three floors and one section, which greatly reduces the manufacturing and processing costs and the standardization of components, and can meet the layout requirements of ventilation and lighting, full open house type, indoor streamline optimization, etc.

△ effect drawing of aoshidi steel structure building is not uncommon in talent housing and public construction projects in Hangzhou, but in the field of commercial housing, aoshidi project designed by Sea southeast is the first pilot project of all steel structure housing in Hangzhou.

△ the more flexible layout of the implicit frame steel plate shear wall structure system makes the indoor free of convex beams and columns, and the innovation of the structural system basically conforms to the current specifications.

Steel structure precast buildings are in line with the dual carbon development goal, and the policy drive has been continuously strengthened.

Both of them adopt implicit frame steel plate shear wall structure and new removable floor bearing plate.

△ the wide steel pipe column implicit frame floor adopts a new type of removable floor bearing plate, which has the same waterproof effect as the cast-in-place plate and is free of formwork, which greatly reduces the on-site construction waste and labor input, saves the budget and time, and is a precast residential product with a high degree of industrialization.

The design team also adopted the flexible connection method of internal foaming adhesive +pe rod + special caulking agent for ALC strip and steel column (including cement mortar leveling outside the fire retardant coating) to delay the problem that the large difference in expansion coefficient between ALC and steel column under the action of temperature difference will cause cracking.

△ schematic diagram of implicit frame steel structure residence the above ground part of the project is a full steel structure system, and the prefabrication rate of main components is 100%.

△ implicit frame steel plate shear wall structure is adopted in the residential part of the site drawing.

All technologies are extensions of human beings—— Marshall McLuhan’s understanding the media under the background of the country’s vigorous development of building industrialization, green buildings have increasingly become the mainstream of the market.

Such a building system has good seismic resistance, can give full play to material performance, reduce resource consumption to the lowest point, greatly reduce construction waste emissions, carbon emissions and dust and noise pollution to the environment, and give full play to the advantages of controllable quality, controllable progress, controllable cost, safety, energy conservation and environmental protection.

Steel structure precast buildings can also be high-quality building spaces with humanistic care.

Located in Qianjiang Century City, the project was recognized as Hangzhou new building industrialization demonstration project in 2021 at the beginning of this year.

△ ALC strip and steel column connection is the “hard core” innovation of building structure, guarding people’s softest living dream.

They are superior to traditional buildings in energy conservation, emission reduction, carbon reduction and other aspects.

In the future, the government will vigorously promote the application of steel structure precast buildings in actual construction.

The significance of sea aoshidi demonstration project is conducive to promoting the popularization and application of precast steel structure construction technology, accumulating architectural experience for Hangzhou to take the lead in building a zero carbon city in the future, and laying a solid foundation for the progress of steel structure precast buildings…
