Description

[Detailed Description of the Invention] "Industrial application field" The present invention relates to an expansion joint device for a column portion of a clean room or the like.

"Problems to be solved by conventional technologies and devices" A dust-free clean room is required to realize high-technology. Conventionally, in order to make a clean room, there is a device provided with a filter for introducing air into the room or devising a door to prevent dust from entering the room when opening and closing. In order to realize more sophisticated high technology technology, not only ventilation and door innovations, but also shutting out microvibration from the power room, soundproof and fireproof structure, and many other things are required Has become. In a building where a gap is provided for vibration prevention and expansion absorption, and the gap is covered with expansion joints, etc., the problem is how to install the expansion joints between the columns that make up the clean room.

[Means and Actions for Solving Problems] Therefore, in order to provide a clean room capable of realizing advanced high-technology, the present invention requires expansion joints to be installed on the columns of the clean room. It penetrates between the pillars.

[Examples] The present invention will be described in detail below based on specific examples shown in the accompanying drawings.

1 and 2 are a longitudinal sectional view and a lateral sectional view showing an outline of a building including a clean room.

In the building, a gap C for absorbing the expansion and contraction of the skeleton is provided in the ceiling 101, floor 102, and pillar 103 for each floor as shown in FIG. 1, and also for each floor as shown in FIG. C is provided. At this time, the gap C may penetrate between the pillars 103.

Various joints are provided in the gap C according to the purpose of each clean room. For example, as shown in FIG. 3, a ventilation cutoff joint A is provided, as shown in FIG. 4, a fireproof / airtight joint B is provided, and as shown in FIG. The joint D is provided with a decorative cover thereon. These third
5 to 5, reference numeral 31 is an airtight sheet, 32 is a fire resistant zone, and 33 is a decorative cover. In a clean room, positive pressure and negative pressure are applied to the room, so air tightness in the room is important.

In FIG. 3, the gap C is covered over the entire length by a long vinyl chloride or EPT airtight sheet 31 with electrostatic prevention and dust prevention as necessary, and a butyl sheet 41 formed with butyl rubber is interposed at both ends. It is located on the upper surface of the body, and is pressed by a long aluminum edge member 43 of extruded shape and screwed with a mounting screw.

In FIG. 4, a refractory zone 32 such as a ceramic fiber is hung on the refractory zone edge material 47, and the other end side is fixed to the anchor 46.

In FIG. 5, the decorative cover 33 is made to cover the gap C through a locking structure such as a W-shaped spring clip and the aluminum edge member 43 '.
Provide on top.

In the above case, the expansion joint must be installed at or near the column. In that case, the following specific structure is used.

Regarding the example of attaching the airtight sheet to the penetration part of the pillar,
It will be described in detail with reference to FIGS.

FIG. 6 is a plan view showing the outline of the whole, showing a state in which the through hole K of the pillar P is penetrated through the airtight sheet 1 of vinyl chloride, and FIG. 7 is a perspective view showing the outline thereof, and FIG. The figure is a perspective view showing the connection procedure of the airtight sheet 1.

The airtight sheet 1 is formed into a gutter shape as shown in FIG.

The pillar-shaped rim member 2 is obtained by fixing an integral mounting angle 6 having bent ends 5 at both ends of an SPC plate material body 4 by welding and bending it between the angles 6 and 6 into an L shape made of SPC. The spring receiver 7 is fixed by welding.

The airtight sheet 1 located in the through hole K of the pillar P is provided with a cut 8 along the side portion of the pillar P so that the upper end of the airtight sheet 1 is along the inner wall of the through hole K of the pillar P and the side portion thereof. Pillar edge material 2
Fix with the press screw 3.

The W-shaped pressing spring 9 made of stainless steel is supported by the spring receiver 7 so as not to drop downward, and the side surface of the pressing spring 9 presses the airtight sheet 1 against the inner wall.

The airtight sheet 1 positioned as described above in the through hole K of the pillar P
The other end of the airtight sheet 1 is connected to the other airtight sheet 1 by superposing the gutter-shaped end portions and adhering with silicon or by welding at the site.

As shown in FIGS. 9, 10, 11, and 12, butyl rubber sheets 10 are attached to the outside of both sides of the airtight sheet 1 located in the through hole K of the pillar P, and aluminum holding edges α are attached to the inside, respectively. Tighten with 3. The spring receiver 7 is fixed to the pressing edge 11 by welding, and the pressing spring 9 is supported and pressed. Between the upper end surface of the airtight sheet 1 and the inner wall of the through hole K, a packing 45 is inserted, and then a silicon sealing 42 is performed.
As shown in FIG. 12, the silicon sealing 42 is continuous with the silicon sealing 42 'other than the through holes.

A spring 9 or the like is inserted so that the airtight sheet is not separated from the wall surface. This is because the clean room receives positive pressure or negative pressure in the room and the airtight sheet receives a large pressure. Therefore, make sure to prevent any leakage with a silicone seal.

13 and 14 show a state in which the through hole K of the pillar P is penetrated by the refractory zone 21.

Reference numeral 22 is a column surrounding material, and reference numeral 23 is a fireproof putty.

The inner and outer surfaces of the upper end of the refractory zone 21 are joined by zinc rivet iron plates 24, 25 and joined by stainless rivets 26. The eleventh
On the right side of the figure, the seam of the refractory zone 21 is shown.

FIG. 15 shows a pillar P in which the airtight sheet 1 and the refractory zone 21 are combined.
The through-hole K of FIG.

"Effect of the invention" As described above, according to the present invention, the expansion joints are installed on the columns of the clean room by inserting the expansion joints between the columns. A clean room that can be realized can be provided.
