Whether the house is strong or not is mainly reflected in the service life of the house and the safety performance in the event of natural disasters, rather than the intuitive experience of pinching with hands and kicking with feet. Traditional brick and cement houses are masonry structures and rigid connections, unable to withstand instantaneous forces such as earthquakes and typhoons. Great external force tearing will lead to structural collapse, while causing secondary damage to life and property.
The main structure of the villa with light steel structure is a keel structure system with high strength and high galvanization, which is joined by high galvanized bolts and forms a whole flexible structure. When encountering natural disasters (such as earthquakes, tsunamis, typhoons, etc.), it can instantly unload external forces, release shear or deformation stresses caused by huge external forces on the building, and ensure the overall safety of the building, even if caused by larger earthquakes and typhoons. The collapse and deformation of houses will also form flexible support space to protect the safety of life and property. The wall of slab composite structure not only has good integrity, but also avoids the secondary damage to human body caused by the collapse of masonry structure.
Sound is also a force, obeying the basic law of energy transmission. The single material wall is limited by the law of quality. It must be heavy wall and thick wall to achieve good sound insulation performance. The light steel structure villa uses multi-layer composite wall, which not only saves the precious building area occupied by traditional bulky wall, but also uses different materials, thickness and multi-layer structure to achieve better sound insulation performance.
Take the exterior wall of light steel villa as an example: the exterior material is the board, which is the integrated board of interior and exterior wall decoration and insulation, the interior material is the gypsum board with coating, and the middle layer is the polyurethane insulation material, which can effectively consume the energy when sound penetrates the wall. The sound insulation capacity of the outer wall of the villa with light steel structure is more than 55 decibels, and the interior wall can be constructed differently according to the need. The maximum sound insulation can reach 66 decibels, far exceeding the sound insulation standard of the national five-star hotel.
Light steel structure villas are green ecological villas, which are not the same kind of products as brick and cement buildings. Traditional buildings are like picture tube TV, light steel villas are like LCD TV. Although they can watch images, they are essentially different. One-time cost of light steel structure villas: According to the same degree of decoration and the same use area, the price of light steel structure villas is only about 10% higher than that of traditional houses.
The comprehensive cost of light steel structure villas: considering the operating cost of the house (more than 75% energy saving of the new building) and the capital turnover (about 50% shorter than the traditional construction period), the excess cost can be recovered within 10 years.
Full cost of light steel villas: Now the cost of traditional brick and cement building is very low, mainly because there is no charge for environmental resources. If the factors such as resource consumption, environmental damage and construction waste after demolition of buildings are taken into account, the cost of traditional buildings is very astonishing. Light steel villas are green recycling buildings. 90% of the building materials can be recycled and reused, which greatly reduces construction waste and carbon emissions. Compared with traditional houses, the comprehensive social benefits of villas are greatly improved, and the total cost price is far lower than that of traditional buildings.
