Description

Backing rings with conductive construction for clean room raised floors

technical field

The utility model relates to a lining ring installed on the periphery of the lattice beam opening of the return air floor of a clean room, in particular to a lining ring with a conductive structure.

Background technique

Semiconductor-related industries or laboratories generally require manufacturing and experiments in a clean room environment due to their high requirements on the process environment. Usually, in order to keep the interior of the clean room clean and dust-free, it will be placed on the floor board of the clean room. The lattice beams with through-holes are set up to provide vertical air circulation through the through-holes, so a higher air cleanliness can be obtained, and the dust generated during the process can also be quickly discharged outside the clean room without affecting other working areas.

It is a well-known simple lattice beam construction technology to use a non-dismantling mold to form a lattice beam structure between floor slabs during the construction of a clean room, such as the grid for a clean room without a raised floor disclosed by the Chinese utility model patent announcement number CN203113583U The beam mold includes a cylinder mold and a cylinder cover. The cylinder mold has a square base and extends upward to form a cylinder body. The cylinder cover is arranged at the top of the cylinder mold. In actual use, multiple molds are connected and arranged side by side. Grout the outer side of the cylinder mold with the cylinder cover on each mold to form a lattice beam structure, and a concave ring is formed on the periphery of the cylinder body. After the cylinder cover is removed, a lining ring can be placed in the concave ring, and then a To make the floor, after placing a cover plate in the lining ring, the cover plate and the floor are connected through the lining ring to complete the construction of the known lattice beam. This mold has the advantage of one-time grouting, and the mold does not need to be removed after the poured concrete dries.

However, for the lattice beam structure completed above, since the general cover plate is made of aluminum alloy, it is easy to generate electrostatic effect on the cover plate due to the people walking back and forth or the moving friction of the machine table, while the general lining ring is made of plastic material. It has no conductive function, so it is impossible to remove the static electricity generated by the cover plate in the lining ring, so that the dust generated in the process is adsorbed on the cover plate, which cannot be removed simply by using the vertical circulation of air between the floor plates, and then It is easy to increase the probability of dust in the clean room process and affect the production quality, so the existing lattice beam structure still needs to be improved.

The conductive effect of the sheet makes it easier to eliminate the static electricity of the aluminum alloy cover.

Further, in the above-mentioned backing ring with conductive structure for the raised floor of the clean room, the conductive sheet most preferably extends from the outer peripheral edge of the top ring along the top edge of the top ring toward the inner edge of the top ring to the step surface and the inner edge of the top ring. The joint at the inner edge of the bottom ring. This technical means extends the conductive sheet from the outer periphery of the top ring to expand the contact area between the conductive sheet and the floor at the outer edge of the ring, and improves the conduction effect of static electricity from the aluminum alloy cover plate to the floor through the conductive sheet, so that static electricity can be eliminated It is more thorough and obvious, so that the static electricity of the aluminum alloy cover can be completely eliminated.

Furthermore, in the above-mentioned backing ring with conductive structure for the raised floor of the clean room, at least one groove is formed on the ring body, and the conductive sheet is embedded in the groove and protrudes from the ring body. surface. This technical means enables the conductive sheet to be more firmly fixed on the ring body by embedding and fixing the conductive sheet in the groove of the ring body. The conductive sheet embedded in the groove protrudes from the surface of the ring body to ensure that the conductive sheet is in contact with the floor on the outer edge of the ring, so as to avoid damage due to slight errors in the size of the floor and the ring body during production. A gap is created so that the floor cannot be electrically connected to the conductive sheet.
