Modern light steel structure integrated house is a young and vibrant steel structure system residence, which has been widely used in office buildings, villas, warehouses, stadiums, entertainment, tourist buildings, low-rise and multi-storey houses and other fields, and can also be used for the reconstruction and reinforcement of old houses, areas lacking building materials, areas with inconvenient transportation, areas with tight construction period, and removable buildings. , favored by the owners. The following are the characteristics of light steel integrated house, and the differences with ordinary steel residential buildings. All parts and accessories are produced automatically, continuously and with high precision, and the product specifications are serialized, finalized and matched. The dimensions of each part are accurate. Structural design, detailed design, computer simulation installation, factory manufacturing, on-site installation, etc. It is carried out simultaneously with a small time difference. Dry construction above the foundation, no wet operation, indoor decoration is easy to reach the designated position at one time. After galvanized coating, the profile is beautiful in appearance and anti-corrosive, which is conducive to reducing the cost of enclosure and decoration. It is not only convenient to expand the column spacing and provide more separation space, but also can reduce the height and increase the building area (the practical area of the house can reach 92%). It has obvious advantages in adding stories, rebuilding and strengthening. The new wall materials have a wide range of applications, a large number of daylighting belts are used, and the ventilation conditions are good. Indoor plumbing electrical pipelines are all hidden in the wall and between floors, with flexible layout and convenient modification. Health, reduce the pollution of waste to the environment, the steel structure material of the building can be recycled 100%, and most other supporting materials can be recycled, which is in line with the current environmental awareness; All materials are green building materials, which meet the requirements of ecological environment and are beneficial to health. Comfort, light steel wall adopts high-efficiency energy-saving system, which has breathing function and can adjust indoor air humidity; The roof has ventilation function, which can form a flowing air chamber above the house to ensure the ventilation and heat dissipation requirements inside the roof. The difference between it and ordinary steel structure residence is that light steel integrated house can replace traditional residence after reasonable bearing capacity calculation; Ordinary steel structures cannot replace traditional houses, and can only be used in large factories, stadiums, super high-rise buildings and other fields. The main material of light steel structure building is light steel keel synthesized by hot dip galvanized steel strip through cold rolling process. Through accurate calculation and supporting combination of accessories, it can play a reasonable bearing capacity and replace traditional houses. Steel structure is a steel-based structure and one of the main types of building structures. Its structure is mainly composed of steel beams, steel columns and steel trusses made of section steel and steel plates, and the components or parts are usually connected by welding, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. Light steel integrated house is movable, all materials can be recycled, and will not cause garbage, which is more in line with the sustainable development strategy than ordinary steel residential buildings. After reasonable bearing capacity calculation, light steel integrated house can replace traditional house; Ordinary steel structures cannot replace traditional houses, and can only be used in large factories, stadiums, super high-rise buildings and other fields. The indoor plumbing and electrical pipelines of light steel integrated room are all hidden in the wall and between floors, with flexible layout and convenient modification. In fact, the application of non-residential buildings in developed countries is very rapid and is expanding to multi-storey residential buildings. Non-residential buildings are mainly portal light steel structures with a span of less than four stories, generally more than 20 meters. It is widely used in the construction of long-span factories such as light industry, electronics, warehouses and processing, as well as supermarkets, temporary houses and hangars for living. Light steel residential buildings are generally used for multi-storey (4 ~ 6 storeys) and high-rise (7 ~ 9 storeys) with a height less than 24m.
