With the promotion of the Internet and the word of mouth of the common people, the light steel villa is basically known to everyone, and everyone knows that there is such a house, whether it is good or bad, there are different opinions. Why is this so? It is not intuitively understood because of hearsay. So some say good, some say bad. In fact, this is not important. What is important is whether you will change the light steel villa after reading this article, and will you recognize it? Let's take a little professional knowledge and take a look at it slowly. Simple life light steel villa, also known as light steel structure house, the main material is light steel keel synthesized by hot-dip galvanized aluminum steel strip through cold rolling technology. Therefore, it is also called cold-formed thin-walled steel. The aluminum-zinc alloy structure of the galvanized steel strip is composed of 55% aluminum, 43, 4% zinc and 1, 6% silicon solidified at a high temperature of 600 ℃, and its overall structural characteristics are composed of aluminum-iron- Silicon-zinc produces a dense quaternary crystal, which in turn produces a strong, reasonable and effective barrier to prevent the penetration of corrosive factors. Therefore, the characteristics of light steel structures are as follows: Cold-formed thin-walled steel 1. Corrosion resistance:“55% Al-Zn-coated steel coil”The corrosion resistance comes from the barrier layer of aluminum guaranteeing the basic function, and the sacrificial layer of zinc guaranteeing the basic function. When zinc is used as a sacrificial protection in trimming, scratches and coating scratches, aluminum will produce an insoluble oxide layer, giving full play to the basic function of barrier protection. Aluminum-zinc alloy steel coils have been subjected to outdoor exposure tests for more than 20 years in a variety of different atmospheric environments. % aluminum-zinc steel plate is appropriate. 2. Heat resistance: The heat resistance of 55% aluminum-zinc alloy steel plate is better than that of galvanized steel plate, and it is similar to the high temperature oxidation resistance of aluminized steel plate. Aluminum-zinc alloy steel plate can be used in high temperature natural environment up to 315 degrees. 3. Reflectivity: The 55% aluminum-zinc alloy steel plate has a high reflectivity, making it a heat-resistant barrier; the heat reflectivity of the aluminized-zinc steel plate is basically double that of the galvanized steel plate. Under specific circumstances, it can also be used as roof and panel to achieve the actual effect of environmental protection and energy saving. 4. Paintability: In view of the excellent adhesion between the zinc layer and the paint of the galvanized steel sheet, it is suitable for the main purpose of the sign board, and it can be painted without pretreatment and weathering treatment; Zinc steel sheet needs weathering treatment and pretreatment. The system composition of the light steel structure villa is divided into the following systems: 1. The basic system The light steel structure villa itself is light in weight, only about one-fifth of the brick-concrete structure house building, The reinforced concrete structure is about one-eighth of the house building, so the basic construction cost can be greatly reduced. The basic structure of light steel structure villas is usually based on strip foundations. ① The light weight of the light steel structure itself can greatly reduce the cost of basic engineering; ② The basic moisture-proof design can reasonably and effectively avoid the intrusion of moisture and harmful gases; ③ The rational anchoring method ensures the reliability of the basic and behavioral subjects connected. Second, the wall system The external wall system is usually between 120-200mm. In view of the thin and light wall, the actual use area of light steel structure villas increases by 10%-15% compared with traditional houses, which is more than the traditional type. Housing construction increases the area used in the room by more than 90%, and the indoor space can be flexibly separated. The pipeline can be laid out in the pre-buried holes of the wall, floor and roof prefabricated components, which is professional and more beautiful. ①The wall is filled with glass fiber wool, which has good thermal insulation, heat insulation and sound insulation performance; ②The breathing paper is waterproof and breathable, which can effectively adjust the indoor air humidity, make living more comfortable, and effectively prevent the growth of mold inside the wall; ③Buried pipelines in Inside the wall, it does not take up indoor space. Light steel villa wall components 3. Floor system The floor is composed 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 the standard modulus, and the floor beams are covered with After strict moisture-proof and anti-corrosion, the structural panels form a solid and earthquake-resistant floor system. ①The combined structure of the structural board and the floor steel beam is firm and stable; ②Various water and electricity pipelines are hidden in the floor structure without occupying the building height; The effect is remarkable. 4. Roofing system The roof truss is assembled by various light steel components. Generally, there are triangular roof trusses and T-shaped roof trusses, which can easily and flexibly realize various complex roof shapes. Generally, the roof adopts colorful asphalt shingles, which have good waterproof performance. Beautiful and better. ①The composite roof has the functions of rainproof, weather resistance, heat insulation, etc., which can realize a variety of shapes; ②The ventilation cycle design keeps the air fresh at all times. 5. Structural components Structural components are all made of high galvanized steel to ensure the service life of the house. All structural components are cold-pressed by the factory's precision mechanical assembly line, and the dimensional accuracy is in millimeters, which is unmatched by other structures. In summary, the light steel villa has excellent physical performance indicators, short construction period and good thermal insulation effect. It is a new type of green, energy-saving and environmentally friendly building structure system. It is the best choice for various types of buildings such as new rural construction, tourist B&B hotels and so on!
