Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a partition structure for a clean room, particularly to a partition structure in which the joint between the partition material and the ceiling is improved.

(Prior Art) The frames of buildings containing clean rooms are typically constructed of reinforced concrete to ensure airtightness and prevent microvibrations, and steel partitions have also been used for clean room partitions. The connection between the partition and the ceiling in such a clean room is usually achieved by attaching an attachment formwork with a U-shaped cross section with an open bottom to the system ceiling frame through a sealant, and baking it to the attachment formwork through rubber packing. The upper end of the painted steel partition is fitted in such a way that it can slide freely. When the beams suspending the ceiling are deflected by wind or other factors, they are designed to absorb the deflection and to ensure airtightness and dustproofing of the outside and inside of the clean room.

(Problem that the invention seeks to solve) Conventionally, the framework of the building containing the clean room was made of reinforced concrete, as mentioned above.
Steel frame construction is being considered to shorten the construction period and achieve long spans, and glass partitions are being considered for the clean room partitions so that the entire internal production process can be seen at a glance.
In this case, when considering the fitting of the joint between the ceiling and the partition, the amount of deflection of the beams due to wind pressure, snow load, etc. is greater in steel frame construction than in reinforced concrete construction, so the deflection of the beams suspending the ceiling is How to absorb the water is an important issue, and the conventional partition structure described above is uncertain because its airtight performance depends on the precision of the adhesion between the steel partition and the rubber packing, and the sliding part Since the rubber packing is in contact with the baked-on steel partition, there were problems such as abrasion of the rubber during sliding and dust generation due to peeling of the paint, impairing the dustproof performance.

(Means for Solving the Problems) In order to solve the above problems, the present invention installs an attachment formwork with a U-shaped cross section that is open at the bottom through a sealing material on the ceiling frame, and attaches it to the attachment formwork. The present invention is characterized in that a partition frame attached to the upper end of the partition material is slidably fitted, and a sealing rubber seal is installed between the partition frame and the attachment form.

(Function) Because of the structure described above, even if the amount of deflection of the beam suspending the ceiling increases, this can be absorbed by the sliding part between the attachment formwork and the partition frame. This space can be reliably sealed by the sealing rubber sheet installed between the attachment formwork and the partition frame, and the sliding part forms a touch between the attachment formwork and the partition frame as described above. , it is possible to eliminate the dust generation caused by rubber wear and paint peeling, which is the case with conventional products.

(Example) Figure 1 is a sectional view showing an example of the present invention.
2 is a system ceiling frame suspended from a beam; 2 is an attachment shape fixed to the ceiling frame 1 with a tap screw 4 via a seal rubber 3; Reference numeral 5 indicates a stainless steel material attached to the exterior of the attachment profile 2, 6 indicates a caulking material applied between the ceiling frame 1 and the attachment profile 2, and 7
is a Teflon sheet coated on the inner circumferential surface of the attachment mold material 2, 8 is a glass partition made of a glass plate, 9 is a stainless steel FB,
Reference numeral 10 denotes a partition frame made of unpainted stainless steel attached to the upper end of the glass partition 8 via a rubber packing 11 and a caulking material 12, and is slidably fitted to the inner circumferential side of the attachment mold 2. 13 has one end attached to the inner peripheral upper surface of the attachment form 2 and the other end attached to the partition frame 10.
Rubber presser 14 and tap screw 1 on the top surface of each
A rubber sheet for sealing is fixed via 5.
As shown in the figure, it is mounted between both members 2 and 10 in a meandering manner.

Incidentally, as shown in FIG. 2, a reflector plate 17 may be attached to the system ceiling frame 1 via a reflector attachment reinforcing plate 16, and the attachment formwork 2 may be attached to this. Further, the structure of the lower end of the partition is the same as that of the conventional one, and therefore a description thereof will be omitted.

With the above structure, the building frame is made of steel, so even if the beams deflect due to wind pressure, snow loads, etc., there will be no problem at the joint between the ceiling and the partition. Can be absorbed. That is, although the ceiling frame 1 moves up and down due to the deflection of the beam, this movement is absorbed by the relative vertical sliding of the attachment form 2 and the partition frame 10.

Conventionally, the airtightness between the inside A and the outside B of a clean room depended on the precision of the adhesion between the rubber packing of the slide portion and the partition material, so it was not possible to ensure sufficient airtightness. However, as described above, since the rubber sheet 13 is installed between the attachment formwork 2 and the partition frame 10, sufficient airtightness can be ensured even when sliding up and down. In addition, the slide part is coated with a Teflon sheet 7 on the side of the attachment form 2 to prevent dust generation, and the partition frame 10 is made of unpainted stainless steel, so the slide part can be moved like a conventional one. There is no dust generation due to rubber wear or paint peeling, and the dustproof performance is significantly improved.

(Effects) As explained above, according to the present invention, even if the frame of the building containing the clean room is made of steel and the clean room partitions are glass partitions, sufficient airtightness between the inside and outside of the clean room can be ensured. At the same time, it is possible to improve the dustproof effect.
