Light Steel Passive House

The light steel villa is composed of structural system, ground system, floor system, wall system and roof system. Each system is composed of several unit modules. The unit modules are manufactured in the factory, and the unit modules are assembled on site. Light steel integrated houses can be disassembled and moved without damaging the land. It has realized the transformation from the "real estate" attribute of the house to the "movable property" attribute for thousands of years, and realized the complete separation of "real estate" and "real estate" for thousands of years. The on-site construction period of the light steel integrated house is 10%-30% of the traditional construction mode. The quality of the integrated house is more refined, realizing the transition from the centimeter-level error of the traditional building model to the millimeter-level error of factory manufacturing.

The characteristics of Shunzhu light steel villa are:
1. Fire resistance: The fire resistance time of the wallboard can reach 5 hours, and the temperature of the back fire surface is only 46 degrees.
2. High strength: By adjusting the space plate thickness and built-in skeleton, the floor bearing capacity is 2.5-5.0KN/m2.
3. Thermal insulation/energy saving: wall thickness = thickness of thermal insulation layer, and the existing energy-saving technologies for building walls in China all adopt the practice of heating and thermal insulation layer on the outer wall.
4. Light weight: the self-weight of space board building is only 20% of that of masonry or cast-in-place structure building, and the weight is saved by 80%.
5. Sound insulation: 120mm thick sound insulation coefficient: ≥45 (dB).
6. Hydrophobicity: The unique cement foam core material of the space board has a closed cell rate of more than 95% and a water absorption rate of less than 2.5%, so it has good hydrophobicity.
7. Durability: safe service life of 90 years.

The advantages of light steel integrated villas:
Compared with traditional brick-concrete structure houses, the advantages of light steel integrated houses with new building materials system are irreplaceable: the wall thickness of general brick-concrete structure houses is mostly 240mm, while the prefabricated houses are in the same area. Below is less than 240mm. Indoor usable area ratio of integrated houses
Traditional brick and concrete structures are much larger.
Light steel integrated houses are light in weight, less wetland operations, and short construction periods. The thermal performance of the house is good, and the wall panel of the light steel integrated house is a foam color steel sandwich panel with heat insulation. Then, most of the building materials used in the light steel integrated house can be recycled and degraded, and the cost is low, and it is a green and environmentally friendly house. In particular, the brick-concrete structure is not environmentally friendly, and a large amount of clay is used, which destroys the ecology and reduces the cultivated land. Therefore, the technological breakthrough and application of light steel integrated houses will be long-term, and will change the traditional construction mode, making human The cost of living has become smaller and the living environment has become better. It can play an important role in environmental protection.
