Metaphora construction method is an H-beam structure that allows any building to be fastened and assembled only with bolts in the field without welding. Structural steel (H-beam and structural-shaped steel) was adopted as a bolt fastening method to increase earthquake resistance, and as a prefabricated steel structure, autonomy in design (thin-bong roof, sloped roof, piloti, and contilver) was secured. With laser-processed precision, the convenience and speed of post-construction processes, construction periods, labor costs, and logistics costs were reduced. It is a nature-friendly well-being health housing method that can be easily renovated and expanded in various forms with a variable wall (non-strength wall), and can apply various building exterior materials.
In particular, five basic low-energy houses (insulation, airtightness, heat bridges, windows, ventilation).It is a prefabricated steel frame systemized with a standard that can easily handle precious insulation, airtightness, and construction of thermal intersections at low cost.
