Development and classification of light steel villas
1. What is a light steel villa?
Light steel villa is a house built by light steel keel, which is supported by precise calculation and auxiliary materials, and assembled into a roof truss system with uniform bearing capacity, and then uses light plates and thermal insulation materials to form walls, roofs and floors. The light steel keel is synthesized by hot-dip galvanized steel strip and cold bending technology. The galvanized steel strip has good toughness, heat resistance and corrosion resistance.
Second, the development of light steel villas
Light steel villas originated in the early 20th century, and France is one of the earliest countries in the world to build light steel villas. Sweden's light steel villas are the most developed, with 95% of residential prefabricated components. American light steel villas were popular in the 1970s. Due to the fast construction speed and low production cost of light steel villas, they are quickly popularized all over the world. At present, various light steel villas have become very popular in many countries such as Finland, Sweden and Denmark. my country's light steel villa market is still in its infancy, but it is developing rapidly and has broad market prospects.
3. Classification of light steel villas
Light steel villas are divided into hollow walls and solid walls.
1. In the hollow wall, the sound insulation cotton fiberglass is mainly added between the light steel keel between the outer wall panel and the inner wall panel, commonly known as "two panels sandwiching one center".
2. The solid wall mainly surrounds the light steel keel with a spider web-shaped all-steel mesh, and then pours concrete in the middle of the steel mesh, commonly known as "light steel light concrete".
Fourth, the construction requirements of light steel villas
1. The requirements for construction design are relatively high. When designing the architectural drawings of light steel villas, in addition to considering the types of components, it is also necessary to consider how the machinery is produced, the hoisting points to the site in the future, how to connect the modules, the safety performance and waterproof performance of the connection points, etc. Therefore, the design The reader should have enough understanding of the construction of light steel villas.
2. The material requirements are relatively high. The main steel of the cold-formed thin-walled light steel house must be made of high-strength and corrosion-resistant materials. Aluminized zinc with the same coating thickness is more corrosion-resistant than galvanized, and S550 is stronger than Q235.
3. The construction requirements are relatively high. Now the connection process of light steel structure houses is an important condition to ensure the quality and safety of the light steel villas built. In addition to being able to understand the construction drawings, the construction team for the installation of light steel villas must also be proficient in installation technology. Therefore, constructors must go through relevant technical training in advance before they can take up their posts, and they must strictly check the details.
