What are the fly in the ointment about the light steel villa? !
Five properties of light steel villas Light steel villas are widely used in the construction of houses due to their good properties such as earthquake resistance, wind resistance, light weight, low cost, heat preservation, durability and environmental protection, so you know what are the light steel villas performance? 1. The seismic resistance and wind resistance of steel structure and wind resistance light steel villas are very good. The data obtained in the earthquake laboratory show that the seismic resistance of light steel villas is 2-3 times that of other traditional houses. The villa adopts light steel structure, the structure has light weight, excellent wind and earthquake resistance, and can resist typhoon 12. 2. Light weight and increase the building area. On the premise, the weight is light, and light functional building materials are used, and the overall weight is about 1/5-1/6 of the brick-concrete structure building. The building foundation requirements are lower than those of traditional buildings, and the project cost is correspondingly reduced. 3. Thermal insulation and thermal insulation performance The exterior wall of the light steel villa is wrapped with extruded plastic board or polyurethane, forming a continuous external thermal insulation, with an excellent thermal insulation layer, warm in winter and cool in summer. 4. Durability, energy saving and environmental protection The energy consumption of light steel villas is 65%-90% lower than that of traditional buildings, which is 10% of the water consumption of traditional construction, and increases the use area of the suite by 10%. And the structural parts are galvanized with special anti-corrosion treatment, which can protect the steel from corrosion and prolong the service life of the steel. 5. Sound insulation and shock absorption Perfect sound insulation and shock absorption technology meet the national building sound insulation standards, especially in the audio frequency of 250 ~ 1000Hz, which is sensitive to the human ear, focusing on professional enhancement to create a quiet and comfortable living environment . What are the fly in the ointment of light steel villas? Light steel villas are not only beautiful in appearance, but also have many advantages, such as warm in winter and cool in summer, sound insulation and heat insulation, anti-earthquake and typhoon resistance, fast building speed, and owners do not need to worry about many other advantages; but today we will first put the advantages and advantages of light steel villas together. Let go, look for her shortcomings, and see if there are still flaws in the ointment that still need to be improved. 1. Do not change and adjust the light steel structure without authorization The masters of the villa construction team, or can understand the drawings, try to nail them on the light steel keel, and the force will be stable; 2. The light steel structure house is different from the traditional structure house, which relies on the construction of various steel components. , and form a solid overall structure, if you make changes to the steel structure without permission, it may affect the safety of living, so it requires professional construction masters of light steel villas to maintain. 2. The price of building light steel villas is not low 1. The cost of light steel villas can be said to be higher than that of ordinary brick-concrete structures. As long as the light-steel villa practitioners do not cut corners, the light-steel structure uses more materials than the brick-concrete structure. In this regard, as long as the owners who have built light steel villas know it, and the customers who have seen the construction of light steel villas also know it; 2. Although the country has been restricting borrowing and making bricks and cement production, the prices of traditional building materials have increased year by year. On the rise, its price is still relatively cheap compared to light steel, and if high-quality waterproof materials, thermal insulation materials and high-quality light steel keel are used for light steel structure houses, it is impossible to fight the price war, so consumers need to wipe Bright eyes, high-quality light steel materials must not be cheap, and the price of light steel villas is not low. 3. The supporting plate technology of light steel is still in the state of continuous updating In comparison, it is relatively weak; 2. Although light steel villas have been built abroad for a long time and the technology is mature, they are only for light steel keels. They are all under constant exploration and may need to be replaced periodically. Of course, there are also problems with brick-concrete structures, but everyone ignores them. 4. At present, the building height of light steel houses cannot exceed 6 floors. Light steel structure houses can only be built with low-rise residential buildings. At present, my country's technology for light steel structure houses with 1 to 3 floors is relatively mature. The new industry standard of the Ministry of Housing and Urban-rural Development 'Technical Standard for Cold-Formed Thin-Walled Steel Multi-Story Residential Buildings' stipulates that no more than 6 floors are allowed, otherwise special treatment will be required. 5. Places with frequent floods should not be built in places with perennial flood hazards. For floods from bottom to top, water will enter the light steel wall, and the water accumulation in the wall will take a long time to dry out. The corrosion resistance of some plates is higher than The red brick and concrete of the brick-concrete house are worse, and the perennial flooding will affect the service life and quality of the light steel villa. Therefore, although the light steel villa is very good,However, since it is still in its infancy, it will take a longer process to change the attitude of the common people, and the national policy support is not very strong. At present, most house building customers are in a wait-and-see state.
