Description

[Detailed description of the invention] [Industrial application field] This invention relates to a lightweight partition for partitioning clean rooms in factories producing electronic and precision equipment, especially IC parts.

In the above-mentioned fields as well as the food and pharmaceutical industries, a high level of cleanliness is required for improving quality, productivity, and hygiene, so clean air is constantly blown from the ceiling to the floor to prevent dust from flying around the room. Therefore, the operating costs of this equipment are considerable. Therefore, if only a part of the cream room is used, this cost can be reduced by partitioning only that part and allowing the blower to work only in that part.

In addition, when replacing, repairing, or newly installing a part of the machines installed in a room, it is best to partition off only the part where the work will be performed so that it will not interfere with work on other production lines. It's convenient.

This is because the repair work and the like is accompanied by the generation of dust, noise, vibration, and the like.

In particular, on production lines for ICs, etc., the production volume cannot keep up with demand, so stopping this line would result in huge losses, so it is advantageous to be able to do other work without stopping this line. It is.

In this way, partitioning the room is very important.

[Conventional technology]

As partition materials for clean rooms, metal plates or surface materials baked with inorganic paint are pasted on the surfaces of gypsum boards or urethane foam, or decorative calcium silicate plates or urethane plates are used.

[Problem that the invention attempts to solve]

All of these are heavy, difficult to install and remove, require skill, and require a machine for assembly, making them difficult to work with, and they also generate vibrations during work and transportation. , and also cause deformation, or the connection between these members has drawbacks such as poor airtightness.

Furthermore, since a large amount of dust is generated during processing such as cutting, it is inappropriate to assemble and use the partition material in the same clean room if there is another production line performing production work.

Furthermore, these partitioning materials are heavy and deformable, so there is a limit to their size.

[Means to solve the problem]

This invention uses lightweight cardboard such as corrugated board, and coats the surface with aluminum foil or vapor-deposited aluminum film to prevent moisture absorption, eliminate dimensional changes, prevent deformation, and make the surface smooth and quiet. The electric treatment prevents dust from adhering to the material, and the paper material makes it easy to cut with a cutter knife.Furthermore, unlike conventional plasterboard or urethane foam, it does not generate dust. It is lightweight and easy to transport and assemble, and does not require any special assembly machinery.
Therefore, there is no vibration during transportation or assembly, which does not interfere with other production lines.

Furthermore, by placing a plastic or metal seal (frame) on the end surface (butt end) of the board and reinforcing each edge with a frame on top of that, it has excellent rigidity and impact resistance and does not deform. Also, large partitions can be obtained.

〔Example〕

Next, the present invention will be explained according to embodiments shown in the drawings.

The central part is a corrugated cardboard body 1 having a multilayer structure, and aluminum foil or aluminum evaporated film 3 with a thickness of 3 to 300 .mu.m is adhered to the side surfaces 2 of the corrugated cardboard body 1. Its surface is
Ceramic paper or vinyl resin is applied to smooth the surface, and at the same time, electrostatic treatment is also performed. The cut end (end) 4 where the truss structure inside the corrugated board is exposed is sealed with a sealing material 5 made of plastic or metal, and a reinforcing frame of metal or plastic is installed along the longitudinal edge of the corrugated board 1. 6 is installed.

These corrugated cardboard bodies are connected by, for example, an H-shaped joint to create a wall that partitions a room.

[Effect of idea]

Since the present invention has the above-mentioned structure, it can be very light in weight, and since the surface is treated with aluminum foil, etc., moisture absorption in the cardboard core can be prevented, increasing dimensional stability and preventing deformation. Furthermore, due to the presence of the surrounding seal frame 5 and reinforcing frame 6, deformation is completely avoided and airtightness is maintained when jointed, and at the same time, the joint material can be easily attached and detached, making assembly work quick and easy. .

Furthermore, if airtight material is incorporated into this part during jointing, even more complete airtight sealing can be achieved.

As such, it is lightweight, easy to work with, and highly airtight, making it ideal as a lightweight partition for clean rooms.
