1. Light steel structure villas generally have 2 or 3 floors. Due to the use of lightweight roofs, the top floor structure bears much less force than other structural layers, so the steel columns can have variable cross-sections to save steel.
2. The steel beams and columns of the roof layer structure can be rigidly connected or hinged. Due to the relatively small cross-sectional size and thickness of this layer structure, welding is easier. If bolted connections are used, the entire structural scheme will be more complex. In order to simplify the construction process, it is best to use rigid connections. The beams and columns can be made of 100-120mm high square tubes or double C-shaped cold-formed thin-walled steel. The column base connection between the roof structure and other structural layers can be either rigid or hinged.
3. For aesthetic requirements, villa residences generally do not allow horizontal and vertical supports, so the structural system of light steel villas generally consists of steel columns and steel beams rigidly connected. The connection between the secondary beam and the main structure adopts a hinged method to simplify the construction process.
4. The light steel structure villa floor slab structure is lightweight, high in strength, with a closed microporous structure and an air sound insulation layer, achieving a sound insulation effect of 41 decibels. It is also easy to install and has a bearing capacity of over 200 kilograms per square meter.
5. Light steel structure villas can be combined into different walls according to the climate and temperature in different regions. In cold regions, a composite wall with both insulation and thermal insulation is formed to ensure that indoor heat is not absorbed or leaked by the wall. Only 1/5 of the energy consumption of ordinary buildings is needed to meet indoor insulation requirements. In hot areas, composite walls are composed of exterior wall panels with hollow convection effects. The solar radiation heat is carried away by the air flowing inside the walls, thus maintaining indoor comfort and coolness.
