3. Compared with concrete structure, steel structure has lighter weight and lower foundation cost;
4. The steel structure is a recyclable material, which is more green and environmentally friendly;
5. Well-designed steel structure prefabricated buildings are more economical than prefabricated concrete buildings.
6. The cross-section of beams and columns is smaller, and more usable area can be obtained.
Save heating costs
Prefab house is more energy-efficient and environmentally friendly when used in the home, such as a new type of thermal insulation layer that has a better thermal insulation effect. When a household measurement is implemented and the heating has the same temperature, the room temperature of the "assembled" space is higher. The head of household may consider lowering the heating temperature, saving heating costs and, at the same time, reducing energy consumption.
Save energy
Finished house is of great benefit for energy saving and environmental protection. Through factory production and on-site assembly, it can significantly reduce building protection and waste water, reduce building noise, reduce harmful gas and dust emissions and reduce building and management personnel on site.
The assembly procedure for the steel construction of the Prefab house: steel column assembly -Installation of the supports between the columns -temporary installation of the steel bearer -roof bearings, roof bearings -correction and fixing of the steel bearer -Installation of the maintenance structure.
1. Contamination protection: Avoid rain water entering the metal roof from the outside. Rainwater enters the metal roof mainly through overlapping joints or knots. In order to achieve the function of the centrifuge, it is necessary to use a sealing disc at the screw connection and to make a concealed fixation. Use sealants or welds on the top of the plate. Best use a long board to remove the overlap. Close water-tight treatment for bleeding.
2. Moisture resistant: Avoid condensation of water vapour in the soil and metal wax layer and drain the water vapour in the metal wax layer. The solution is to fill the metal roof with thermal insulation cotton, place a waterproof membrane on the metal floor plate and have ventilated knots on the metal roof.
3. Daylight: Improve indoor lighting during the day by means of skylights and save energy. When installing daylight panels or daylight glass at certain points on the metal roof, the duration of use of the daylight should be aligned with the metal ceiling panel and the connection between the daylight and the metal ceiling panel should be treated watertight.
