In general, microdusts and microorganisms that deal with small genes in cells, such as ultra-high density integrated circuits (VLSI) or genetic engineering, which can assemble 100,000 or more transistors or resistors in a size of only a few mm2, have a great effect. Exerted. For this reason, a clean room is used, which is clean by filtering or aspirating air throughout the room. In addition to the clean room, there is also a high-safety laboratory in which a box-type experiment box is strictly controlled to prevent bacteria from leaking out.

In particular, dust is fatal in the VLSI process. Moreover, the average human being scatters thousands of pieces of dust every minute in skin clothing. Therefore, it is better not to let people into the clean room as much as possible, but in reality, most people have to go in and work.

The ceiling frame is composed of a plurality of Jangba 10 and Danba 20, the connection assembly 12 is disposed at the point where the Jangba 10 and the Danba 20 meet. In the present specification, jangbara refers to a bar extending in the horizontal direction and a long length, short bar refers to a bar extending in the longitudinal direction and short. The conventional connecting assembly 12 for connecting the long bar 10 and the short bar 20 has a substantially + -shaped structure, each of which is connected by a joint bolt 14 to the long bar 10. ) And the end of the end bar 20 is coupled. Jangba 10 and danba 20, which are joined by a connection assembly 12, provide a plurality of rectangular grids, which have fan assemblies 30 and blind panels, as shown in FIG. 2. 40 are alternately arranged.

As described above, in the conventional ceiling frame assembly structure, since the long bars 10 and the short bars 20 are coupled using the + -shaped connection assembly 12, the bonding strength of the entire ceiling frame is low. Therefore, conventionally, in order to reinforce the bonding strength, a hanging channel 38 is installed on the wall 36, and then a plurality of turn buckles 42 are vertically installed on the channel 38 to form a ceiling frame. At the same time, the fan assembly 30 is secured using a plurality of oblique turn buckle 44. In the fan assembly 30, a fan 32 which is rotated by a motor is mounted, and a filter 34 is attached to the lower part to collect dust.

As such, in the conventional ceiling frame assembly structure, since the coupling strength is low, a large number of turn buckles are required, so it takes a long time to assemble it and the structure is complicated.

The present invention for solving the above problems consists of a jangba extending in the longitudinal direction as a single unit, at the same time to secure the connection assembly by using a joint bolt and nut, the both sides of the connection assembly By fixing the two end bars, respectively, it is possible to improve the overall bonding strength of the ceiling frame and shorten the assembly time, and to provide a ceiling frame assembly structure of a clean room that can simplify the structure of the entire ceiling frame.
