What is the difference between the light steel villa built by Lu Gong, the whole house and the integrated wall decoration?

Light steel structure is a young and vibrant steel structure system, which has been widely used in general industrial and agricultural, commercial and service buildings, such as office buildings, villas, warehouses, stadiums, entertainment, tourist buildings, low-rise and multi-storey residential buildings. It can also be used for storey addition, reconstruction and reinforcement of old houses, areas lacking building materials, areas with inconvenient transportation and tight construction period, movable and detachable buildings, etc. , favored by the owners. It mainly has the following characteristics: 2) 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. 3) Structural design, detailed design, computer simulation installation, factory manufacturing, on-site installation, etc. Should be done at the same time, the time difference is very small. 4) Dry construction above the foundation, no wet operation, and 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. 5) It is convenient to expand the column spacing, provide more separation space, reduce the story 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. 6) The new wall materials have a wide range of applications, a large number of daylighting belts are used, and the ventilation conditions are good. 7) Indoor water heating and electrical pipelines are all hidden in the wall and between floors, with flexible layout and convenient modification. 8) The house can be moved, all materials can be recycled, and no garbage will be generated, which is in line with the sustainable development strategy. 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. By adding energy dissipation members such as energy dissipation braces, residential light steel structures can also be used in higher floors. Residential light steel structures are mostly frame structures composed of hot-rolled H-beams, and the joints are connected by high-strength bolts (supplemented by welding). The floor is mostly reinforced concrete structure, and the formwork is replaced by steel base plate. Roof panels and external walls are mostly color-coated steel plates that integrate heat preservation and waterproof, and household walls are mostly waterproof lightweight wallboard. 2. Earthquake resistance: The roofs of low-rise villas are mostly sloping roofs, so the roof structure is basically a triangular roof truss system composed of cold-formed steel members. After the structural plate and gypsum board are sealed, the light steel members form a very strong "plate-rib structure system", which has stronger seismic and horizontal load resistance, and is suitable for areas with seismic intensity above 8 degrees. 3. The invention has the advantages of light weight, high strength, good overall rigidity and strong deformability. The weight of the building is only one-fifth of that of the brick-concrete structure, which can resist the hurricane of 70 meters per second and effectively protect life and property. Durable light steel residential structures are all composed of cold-formed thin-walled steel members, and the steel ribs are made of ultra-anti-corrosion high-strength cold-rolled galvanized sheet, which effectively avoids the corrosion of steel plates during construction and use and prolongs the service life of light steel members. The structural life can reach 100 years. 4. The thermal insulation material used for thermal insulation is mainly glass fiber cotton, which has good thermal insulation effect. The insulation board used for the external wall can effectively avoid the "cold bridge" phenomenon of the wall and achieve better insulation effect. The thermal resistance of R 15 thermal insulation cotton with a thickness of about 100mm can be equivalent to that of a brick wall with a thickness of1m. 5. Sound insulation and sound insulation effect is an important index for evaluating houses. The windows installed in the light steel system are made of insulating glass, which has good sound insulation effect, and the sound insulation reaches more than 40 decibels; The sound insulation effect of the wall composed of light steel keel and thermal insulation gypsum board can reach 60 decibels. 6, healthy dry operation construction, 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. 7. Comfortable 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. 8, fast dry operation construction, not affected by environmental seasons. A building of about 300 square meters needs only five workers for 30 working days to complete the whole process from foundation to decoration. 9. Environmental protection materials can be recycled 100%, which is truly green and pollution-free. 10. Energy-saving walls are efficient and energy-saving, with good thermal insulation and sound insulation effects, which can reach 50% energy-saving standards.
