Anonymous users2024-01-23At present, there are three types of sofa skeleton structures that are the mainstream.
The first is the solid wood structure skeleton, the wooden part of a good sofa is mostly phenolic resin rubber board, rubber wood, imported foreign miscellaneous wood, after drying and drug treatment, corrosion resistance, no deformation. The wooden frame is made of hard solid wood that has been dried and disinfected at high temperatures, with a humidity of less than 13 degrees Celsius, which is mildew and moth-proof. The frame of the solid wood sofa should be a mortise structure, which cannot be connected with nails, because the solid wood structure has very strict requirements for the process, and the sofa of the real solid wood structure is also expensive, so this kind of structural sofa is quite rare.
The second is the plank timber structure, that is, the structural skeleton made of beams and vertical supports with timber squares, combined with multi-layer composite panels and nailed. This kind of structural material has low cost, simple manufacturing process, convenient molding, high manufacturing efficiency, and is a kind of process structure widely used at present. However, the shortcomings of the plank structure are also quite obvious, which is easy to cause pollution and emit peculiar smells.
The third is an all-steel welded structure, that is, an ordinary standard square steel pipe is welded and formed under a standard mold, and then anti-rust treatment is carried out. This process is difficult to form, the working time is long, and the technical requirements are high. However, the structure has good stability, high strength, good environmental protection and long service life.
The skeleton of a good sofa is made of imported steel, which is cut and welded by precision machines, and its hardness and thickness are in line with international standards.
