It is being used.

In addition, a clean room is also called a clean room because it generally refers to a room in which there is no dust or foreign matter inside any compartment. These clean rooms are used for ultra-high-precision integrated circuits, genetic manipulation, and the use of drugs or chemicals in a clean state. It is installed in cases where contamination may cause defects or have a significant impact on quality, such as in places where products are handled. Clean rooms like this are equipped with many cleaning devices to remove dust coming in from workers' clothing or bodies or from the outside to ensure clean rooms. Clean air with dust removed is continuously supplied to the inside of the clean room. , It is equipped with an airflow control system such as an air conditioner to quickly discharge indoor dust-containing air to the outside. In these clean rooms, walls and ceilings are built to maintain clean air indoors, and profiles are used as basic structures to build the walls and ceilings of the clean room. In addition, profiles are generally extruded from aluminum and have the advantage of being light, high strength, and capable of being manufactured in various shapes.

In addition, it is easy to change the structure after installation and is inexpensive, so it is widely used not only in clean rooms, but also in various facility structures or laboratory tables.

These profiles are used by assembling vertical and horizontal profiles of the same structure to form right angles in a grid to suit the construction design.

To briefly explain the structure of the profile, a fastening groove is formed along the longitudinal direction on at least one side (generally, in the case of a square profile, one or more fastening grooves are formed on four sides), and a vertical profile and a horizontal profile are formed. They are connected at right angles and assembled into a structure. At this time, various methods can be used to connect the vertical profile and the horizontal profile. The most common method is to drill a screw hole in the profile and assemble it using bolts. In the case of the method, it is easy for external air or foreign substances to penetrate into the interior through the screw hole. , it is difficult to use it for clean room purposes because there are problems such as dust and other foreign substances generated when tightening bolts falling inside.

Accordingly, in order to meet the purpose of a clean room, various fasteners are used to fasten vertical and horizontal profiles. Conventional fasteners have limitations in the assembly form of the profile, are limited in the assembly area, or do not have sufficient assembly strength. Even if conventional fasteners are used, most clean rooms are constructed by drilling screw holes in the profile and connecting them with bolts, which is the cause of defects during clean room work. There is a limitation in that it cannot fundamentally solve problems such as the generation and falling of foreign substances such as dust.
