DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure of a partition panel used in a clean room or the like.

[0002]

2. Description of the Related Art In general buildings, sealants are used as joints at connecting portions of partition panels. However, the sealant generates a gas that is not preferable for precision machines and the like. For this reason, in a clean room or the like, a connection structure is used in which two partition panels are connected to each other using a joint fitting made of aluminum as a base material, or one partition panel is fixed to a floor, a ceiling, or the like. . For such joint fittings, resin packing is used to ensure airtightness.

[0003]

However, in the conventional panel connection structure using the joint fitting, the holding performance of the resin packing is not sufficient, and the packing often comes off easily from the joint fitting. There was a problem with workability at the site. Further, the strength for holding (fixing) the panel was not sufficient. Further, since the resin packing is fitted to the joint fitting, there is also a disadvantage that the thickness of the connecting portion is increased. Further, it is required to improve the airtightness of a connecting portion connecting the panels.

The present invention has been made in view of the above situation, and has as its main object to provide a connection structure having excellent holding and airtightness of a partition panel.

Another object of the present invention is to provide a panel connecting structure that can reduce the thickness of a connecting portion. Also,
One of the objects is to provide a connection structure that is excellent in holding properties of a resin packing.

It is still another object of the present invention to provide a method of connecting partition panels which is excellent in workability on site.

[0007]

In order to solve the above-mentioned problems, a connecting structure according to the present invention comprises a joint member formed of a hard material and a resin packing disposed between the joint member and the partition panel. And The joint member has a hollow holding portion into which one end of the partition panel is inserted, and an outer surface exposed to the outside.
Further, the resin packing has a first fitting portion fitted to a part of the outer surface of the joint member, and a holding portion arranged between the joint member and the partition panel.

In the present invention having the above-described structure, the resin packing is disposed over both the inner and outer surfaces of the joint member so as to sandwich the edge of the joint member. There is an effect that the thickness can be reduced. In addition, the holding portion of the resin packing comes into contact with the surface of the panel, instead of the joint member coming into direct contact with the surface of the panel, so that the retention and airtightness of the panel are improved. Further, since the panel is held by the resin packing instead of the joint member, the dimensional error of the panel can be adjusted on site, and the so-called labyrinth effect is improved. That is, in the present invention, there is an effect that the panel can be reliably fixed by a complicated structure such as a maze.

In the case where the resin packing is provided with a second fitting portion for fitting with a part of the hollow holding portion of the joint member, the outer frame of the joint member is formed by the first and second fitting portions. Since the resin packing is fixed so as to be sandwiched, the holding property of the resin packing to the joint member is improved, and the resin packing does not easily come off from the joint member. Further, if a plurality of protrusions protruding toward the panel are provided in the holding portion of the resin packing, there is an effect that the airtightness of the connection portion is further improved.

Preferably, the resin packing includes a base fitted to the joint member and an extension extending from the base toward the outside of the joint member and in contact with the surface of the panel. Then, the extension portion is formed of a soft resin, and the base portion is formed of a hard resin. With this configuration, the base made of the hard resin fits with the joint member, and the extension made of the soft resin comes into contact with the panel. Therefore, the airtightness is high without impairing the fitting strength with the joint member. Character can be obtained.
