Synthetic resin panel

The present invention relates to the manufacture of a panel, and more particularly, the upper plate and the lower plate, and the extension extending in various forms therebetween integrally formed by extrusion molding, exhibiting excellent strength and space utilization, and the manufacturing process is improved. A simple synthetic resin panel.

In order to solve the drawbacks of the conventional wood or steel panels, recently developed panels are made by injecting and foaming a synthetic resin stock solution between steel sheets coated with silicon polyester or fluorine, or by placing a cured synthetic resin material. These products have improved fire resistance, heat insulation, safety and ease of construction.

For example, sandwich-type insulation panels have been developed in which laminated steel sheets coated with polyester or fluorine are coated with a special adhesive method on foam molded polyester. These panels have been developed for general prefabricated buildings, transportation vehicles, various factories, and refrigeration. It is applied to various buildings such as refrigeration and low temperature warehouses, parking towers, shopping malls, exhibition halls, offices and houses

Korean Patent Registration No. 0174788, filed on April 4, 1995 and registered on November 6, 1998, discloses a synthetic resin construction panel, which uses an extruder to make curved plate parts and hardens them.
