Modular Prefabricated Light Steel Villa

1. Basic system
It can adopt various forms such as strip foundation, crawl space, basement, etc., with strip foundation being the main form. The double-story house must be dug 400mm-600mm deep underground, and a 240mm-300mm high structural ring beam should be set above the ground. The specific construction geological conditions and house foundation design drawings shall prevail. Light steel structure houses are light in weight, only about one-fifth of brick-concrete structure houses and one-eighth of reinforced concrete structure houses. Therefore, they can greatly reduce the cost of foundation construction. Light steel structure houses generally use strip foundations. .
2. Wall system
The inner substrate is calcium silicate board; the structural board OSB board (9.5mm) is imported from Canada; the outer decorative layer can be cement fiber hanging board/local cultural stone/American paint; the thickness of the exterior wall is generally 120-200mm; because the wall is relatively thin, Light steel structure houses have about 10%-15% more actual use area than traditional houses; the indoor use area of light steel structure houses reaches more than 90%, the indoor space can be flexibly divided, and pipelines can be built and reserved on the walls, floors and roofs The layout of the holes is good for concealment and more beautiful.
Key points: Thin walls, light weight, large usable area of the house, and beautiful appearance.
3. Floor system
The floor system is mainly truss type, with light steel beams with a height of 305mm and assembled from standard small rods. 18mm thick OSB structural panels are laid on the floor beams, and a 40mm thick lightweight concrete cushion (crack-resistant sound insulation layer) is placed on top. Wooden floors, ceramic tiles or carpets can be used as the floor decoration layer. The floor is made of a combination of high-strength hot-dip galvanized C-shaped and U-shaped light steel components. The floor beams are arranged with dense ribs at equal intervals according to standard modules. The floor beams are covered with structural plates that have undergone strict moisture-proof and anti-corrosion treatment to form a solid structure. Earthquake-resistant floor systems.
Key points: earthquake resistance, sound insulation, tight joints on the floor, and prevention of leakage.
