Description

[Detailed description of the invention] The present invention relates to a partition structure, and is intended to provide a partition structure that is particularly suitable for use in clean room partitions. It is characterized by absorbing dust and preventing it from being transmitted to the floor, preventing the generation of dust from the partition itself, and blocking the flow of dust between adjacent rooms separated by the partition.

Examples of the present invention will be specifically described below.

The ceiling 1 is composed of frames 2 assembled in a grid pattern and filters 3 filled between these frames.

The ceiling rail 4 has a substantially U-shaped cross section and a horizontally elongated form, and its base 5 is fixed to the frame 2 via vibration-proof packing 6 with bolts 7 and nuts 8.

The packing 6 is made of rubber, has a rectangular cross-section, and extends horizontally, absorbs the vertical vibration of the frame 2 and does not transmit it to the floor 9. By forming narrow grooves on the upper surface of the packing 6 and bringing the protrusions 10 between these grooves into contact with the frame 2, vertical vibrations of the frame 2 are further absorbed.

The cap 11 has a substantially U-shaped cross section with a partition wall 12 formed in the middle, and extends in the horizontal direction. It fits inside the ceiling rail 4.

Side wall 14 of ceiling rail 4 and side wall 14 of Kasagi 11
A vibration-proof packing 15 and a guide piece 16 are provided between them. The anti-vibration packing 15 is made of soft rubber, has a hollow cross-section, and extends in a long shape.
A part of it is pushed into a groove in the side wall 14 of the ceiling rail and fixed. This anti-vibration packing 15 absorbs the lateral vibration of the cap 11 and
The fitting surfaces of the ceiling rail 4 and the ceiling rail 4 are made airtight to prevent dust and dirt from passing through. The guide piece 16 is made of a hard synthetic resin having self-lubricating activity, such as nylon resin, and a part of the guide piece 16 is fitted into a groove in the side wall 14 of the ceiling rail 4 and fixed thereto. This guide piece 16 is Kasagi 1
The cap 11 is guided in the vertical direction while preventing excessive lateral vibration of the guide piece 16 and the cap 11, and no dust is generated on the sliding surface itself between the guide piece 16 and the cap 11.

The Kasagi 11 is supported by a support 17, which supports the floor 9.
It is fixed to with floor rails 18 and baseboards 19.

Like the ceiling rail 4, the floor rail 18 has a U-shaped cross section and extends horizontally, and the baseboard 19 has a substantially H-shaped cross section and extends horizontally. The floor rail 18 is fixed to the floor 9 with bolts 22 and nuts 23 via an anti-vibration packing 20 and a base plate 21, and a baseboard 19 is fitted to the floor rail. These floor rails 18 and baseboards 19 pass through cutout grooves at the lower ends of the columns 17. The baseboard 19 is supported by the head of a bolt 24, which is screwed into a member 25 having an inverted U-shaped cross section and supported by the floor rail 18.
The height of the baseboard 19 is adjusted by threading this bolt.

The panel 26 is fitted into a space surrounded by the cap 11, the baseboard 19, and the post 17, and the lower side and both sides of the panel are fixed to the baseboard 19 and the post 17 via packing 27 and presser edges 28, respectively. Further, the upper side of the panel 26 passes through a pair of packings 29 fixed to the cap 11 and is supported so as to be relatively movable in the vertical direction.

Air is sent out from the filter 3 on the ceiling 1 and flows to be sucked into the floor 9, and at this time vibrations are generated in the ceiling as described above. This vibration tries to be transmitted to the floor in the vertical and horizontal directions, but it is absorbed by the packings 6, 15, 20, and 29 and its transmission is prevented. Furthermore, when vibration occurs, the ceiling rail 4 moves relative to the cap 4 to prevent the panel 26 and the support 17 from being bent.

In the partition structure of the present invention, a cap 11 is fitted to a ceiling rail 4 fixed to a ceiling 1 so as to be relatively movable in the vertical direction, and a soft rubber or A vibration-proof packing 15 having the same properties as the above is provided in an airtight manner, and is made of hard synthetic resin with self-lubricating activity that guides the ceiling rail 4 that follows vertical vibrations of the ceiling in the vertical direction relative to the Kasagi 11. Guide piece 16 to Kasagi 11
The structure is such that there is enough play to prevent excessive lateral vibration of the ceiling, and partition panels and pillars are attached to the ceiling, so that when the ceiling vibrates due to air supply, etc. The vibration is absorbed by the relative movement of the ceiling rail 4 and the Kasagi 11,
Lateral vibrations are absorbed by the anti-vibration packing, so no vibrations occur on the floor or panels, and the guide piece 16 slides smoothly against the cap 11 to suppress the generation of dust and prevent it from occurring. The packing 15 prevents waste from scattering from the cap into the room, and the packing 15 also prevents the movement of waste between adjacent partitioned rooms, and even if the cap is swayed sideways, the guide piece 16 keeps the packing 15 in close contact with the cap 11. This prevents the movement of waste between adjacent rooms.
