Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lower structure for supporting a wall panel which constitutes a so-called clean room.

[Conventional technology]

Conventionally, the wall panel a of a clean room that requires cleanliness is
As shown in FIG. 5, a base material b having a substantially U-shaped cross section is fixed on the floor, and a lower part of the panel is inserted through a spacer d on a pair of horizontal sides c inside the base material b. The sealant e is applied and the rising portion of the floor sheet g inside the room is housed in the groove f at the upper ends of both sides of the base agent.

As shown in FIG. 6, support rails j are set above the base h fixed on the floor via bolts and nuts i so that the support rails j can be adjusted up and down. In some cases, a wall panel a having a recessed line on the lower surface and wider than the above base is placed, and a rising portion of a floor sheet g is added to the outside of the skirting board k.

[Problems to be solved by the device]

However, the former former has good workability, but has the drawback that dust easily accumulates on the sealant e, while the latter does not have this drawback, but requires a large number of members, requires a lot of construction work, and requires skill. There was also a drawback that the tree k could come off due to some external force. In order to solve these drawbacks, a plan to provide stepped portions on both lower sides of the wall panel itself was considered, but it was not realized because productivity was poor and cost was high.

[Means for solving the problem]

The present invention solves the above-mentioned drawbacks of the prior art and is easy to install,
It is designed to achieve the standing of a wall panel that does not collect dust. Specifically, a base material having a substantially U-shaped cross section is fixed on the floor, and a support seat and a spacer are provided inside except for the fixing portion. The guide ridges, which are wider than the base material and hang down on the lower side of the wall panel, are inserted into the base material and placed on the spacers to set up the wall panels, and the reverse formed on both sides of them. The rising portion of the floor sheet in the room is housed in the L-shaped step portion, and a sealant is applied between the edge of the room and the step portion for sealing.

According to a second aspect of the invention, a horizontal side corresponding to the fulcrum is integrally provided inside the base material, and a ridge of the panel is placed on the horizontal side via a spacer.

[Action]

According to the present invention, the wall panel can be leveled by fixing the base member with anchor bolts and the like and inserting the support seat and the spacer of a predetermined thickness, and dust is not collected on both sides of the panel.

Further, according to the second invention, the construction can be performed by omitting the support seat.

〔Example〕

1 and 2 show a first embodiment of the present invention, in which a base member 3 of a substantially U-shaped cross section having a bottom piece 1 and both side pieces 2 made of an aluminum profile on the floor surface FL is an anchor bolt 6 or the like. Fixed by.

A support seat 10 having a rectangular cross section is inserted into the inside 4 of the base material 3 except for the anchor bolt 6, and a plurality of spacers 12 are provided on the upper surface of the support seat 10 at intervals. It is placed with a thickness according to the level.

The wall panel 15 is such that a core material 17 such as asbestos honeycomb or hard urethane foam is filled between a pair of surface plates 16 and 16, and an aluminum-shaped frame material 18 having a substantially U-shaped cross section is arranged on four sides.

A guide ridge 20 having a substantially C-shaped cross section is provided on the lower side of the wall panel 15.
However, they are fixed by screws 23 that enter into the narrow groove 19 in the center of the frame member 18.

Then, the guide ridges 20 are inserted into the inside 4 of the base material 3 and placed on the spacers 12 so that the wall panel 15 is attached to the base material 3.
Stand on top.

Since the wall panel 15 is larger than the width of the base material 3, the inverted L-shaped step 25 is formed on both sides of the wall panel 15.
A rising portion 28 of a floor sheet 27 in the room is housed in 25, and a sealant 30 is applied between the edge of the floor sheet 27 and the step portion 25 to seal the two.

FIG. 3 shows a modified example of the wall panel 15, in which only the lower side of the four circumferences of the wall panel 15 is integrally formed with the guide ridges 20.
By using 18 ', it is intended to eliminate the work of screwing and improve workability on site.

FIG. 4 shows a second embodiment of the present invention. In order to omit the support seat 10 of the first embodiment, a horizontal support piece 5 is installed in the inside 4 of the base material 3 at the same height as the support seat 10. It is formed integrally with an aluminum shape member in advance, and a large-diameter through hole 5a for operation is opened and used only in a portion where a fixing tool such as the anchor bolt 6 is used.

It should be noted that a plurality of small ridges 3a for reinforcement are provided on the inner surface of both sides 2 of the base material 3.

Also, small shoulders 21 are provided on both side shoulders of the guide ridge 20, and the bent portion 16 of the face plate 16 is formed between the guide ridge 20 and the frame member 18 of the wall panel 15.
It holds the tip of a (see Fig. 2). However, in the case of the second embodiment, since the guide ridge 20 is an integral frame member 18 ', small grooves 18 "are horizontally formed on both sides thereof (see FIG. 3). In FIG. 2, 22 is a positioning strip of the guide ridge 20.

Further, the floor sheet 27 may be laid only on one side of the wall panel 15, and the rising portion 28 thereof may be housed in the step portion 25. In this case, the side piece 2 of the base material 3 on the side without the floor sheet 27. A sealant 30 such as silicone caulking is applied between the upper end of the wall and the lower surface of the wall panel 15.

In addition, the support seat 10 is not limited to have a rectangular cross section, and a channel-shaped one having a downward opening may be used.
It can also be used to insert an electrical wiring, an optical fiber cable or the like into the space below the interior 4 of the base material 3.

〔effect〕

According to the present invention, the following unique effects can be obtained.

(1) The leveling of the wall panel can be accurately performed and the construction can be performed quickly and easily without increasing the number of members.

(2) Dust is not accumulated in the lower part of the wall panel, and the wall panel is not displaced or falls off due to external force, etc., and maintenance is unnecessary, and durability is improved.
