Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an inorganic fiber partition membrane used in various work sites, and a membrane element for forming this membrane.

(Prior Art) For example, as disclosed in JP-A-2-92844, there is an antistatic cloth used to surround a coating work area to prevent the escape of paint mist and solvent vapor. Proposed.

In order to assemble a partition (or wall) membrane surrounding a work site using this conventionally proposed cloth, a large number of pieces of inorganic fiber cloth are sewn together with metal threads in advance outside the work site. Must be brought to the site and assembled, or suture assembled at the site.

(Problems to be solved by the invention) However, since this partition membrane has a size of 5 to 6 m or more in the vertical direction or 15 m or more in the horizontal direction when used in a work site such as aircraft assembly, It is difficult to assemble this at a site other than the work site and bring it to the site.
Further, it is troublesome to sew the membrane element piece on site, because bringing a sewing machine or the like to the site is troublesome, and the on-site sewing is difficult because the inorganic fiber is easily broken or damaged.

An object of the present invention is to provide an inorganic fiber partition membrane and a membrane element piece thereof having a structure that can be assembled as a partition (or wall) membrane relatively easily on site.

(Means for Solving the Problem) In order to achieve this object, according to the inorganic fiber partition membrane of the present invention, a tooth formed of a conductive material and a cloth portion fixing the tooth are provided. The cloth portion is formed of conductive fibers, or the cloth portion is provided with a conductive layer, and the plurality of inorganic fiber membrane pieces are connected to each other by the conductive fasteners. It is characterized by being combined with.

In carrying out this invention, it is preferable to attach rope-shaped lead to this partition film body.

Furthermore, according to the element of the inorganic fiber partition membrane, it has teeth made of a conductive material and a cloth portion fixing the teeth, and this cloth portion is made of conductive fibers. Or a conductive fastener element formed by providing a conductive layer on the cloth portion, and the conductive fastener element is provided on the bonding side edge of the membrane element piece of the inorganic fiber.

In carrying out the film element, it is preferable to attach rope-shaped lead to the film element.

(Operation) According to this partition film body structure, the film body pieces are joined by the conductive fasteners. The conductive fastener has a conductive tooth and a conductive cloth portion fixing the tooth.
The fabric portion is formed of conductive fibers or provided with a conductive layer of the fabric portion. Therefore, if the conductive fastener is grounded to the ground or the like, the conductive fastener itself has a structure in which electricity can be satisfactorily conducted, and thus the static electricity charged in the fastener can be easily released to the ground. This conductive fastener is composed of a pair of fastener pieces that can be detached from each other, and one fastener piece should be provided on one film body piece to be joined, and the other fastener piece to be joined should be joined. It is provided on the other membrane element. Therefore, since it is sufficient to assemble the film body pieces by the work of joining the film body pieces to each other with the conductive fastener, it is possible to assemble them easily on site. Further, since it is carried in to the site in the form of a film element having a small size, it is easy to carry.

Further, since each film element is connected by the conductive fastener, charged static electricity can be easily released from the partition film to the ground.

In addition, when the partition membrane body is used by hanging it in the shape of a lantern, for example, it is possible to tension the partition membrane body by attaching a lead rope parallel to the floor surface to the membrane body or the membrane body piece. Further, even if there is an obstacle on the floor, the lead rope is flexible, so that the partition can be formed by being deformed to the upper side of the obstacle.

(Example) Hereinafter, the structures of the inorganic fiber partition membrane and the membrane element of the present invention will be described with reference to the drawings. The figure shows
The shapes, sizes, and positional relationships of the respective constituents are only schematically shown to the extent that this invention can be understood.

FIG. 1 is a front view schematically showing a film body element for forming a partition film body. Further, a part of the assembled partition membrane is schematically shown by 20 in FIG.

Antistatic treatment is usually applied to prevent explosion caused by static electricity sparks. Then, it is required to be nonflammable against ignition such as sparks.
Therefore, in this example, an example in which the inorganic fiber subjected to the antistatic treatment is used will be described.

The film element 10 is made of non-combustible inorganic fiber such as glass fiber, and its surface is subjected to antistatic treatment. A reinforcing strip-shaped metal sheet 12 is provided on a part or the entire circumference of the element piece 10 and at appropriate positions in the vertical and horizontal directions. The film itself of the film element may be conventional.

The film element of the present invention has a structure in which one fastener element 14 of the conductive fastener 16 is attached to a part or almost the entire circumference of the film. As the conductive fastener 16, for example, a metal fastener may be used. still,
The term "metal fastener" used here means that the teeth (tabs) are made of a metal material, and the cloth part fixing the teeth may be made of metal fibers, or the cloth part is provided with a metal layer. May be In short, the cloth part for fixing the teeth may be subjected to the antistatic treatment. In addition, the fastener element 14 may be sewn to the membrane element element with, for example, a metal thread. A part or almost the entire circumference of the other film body piece to be combined with one film body piece, the other part to be combined with the conductive fastener piece 14 of the one film body piece described above. The fastener element 14 may be attached. In the example of FIG. 1, the fastener pieces are provided on both the left and right sides of the film piece, but they may be provided on the upper and lower edges.

In this way, since each film element piece is attached with the fastener element pieces 14 that are bonded to each other, if these fastener element pieces 14 are connected, the respective film element pieces 10 are also connected by the conductive fasteners 16. A single large antistatic inorganic fiber partition membrane 20 is assembled and configured.

The embodiment shown in FIG. 2 shows the front surface of a partition membrane having a structure in which a plurality of membrane pieces 10 provided with fastener pieces 14 on the left and right sides are arranged side by side in a lateral direction. Of course, up and down,
A plurality of film element pieces provided with fastener elements on the entire circumference on the left and right sides may be fastened to each other to form one partition film element.

The mechanism that actually drops this partition membrane at the work site is
Since it is well known in the art, a detailed description thereof will be omitted,
The partition membrane is suspended at multiple points on the metal beam 24. Furthermore, the metal ropes 22 are attached in parallel to the required multiple locations of the partition membrane, and the partition is performed in the same manner as "Doncho". Raise and lower the membrane. Therefore, the static electricity charged on the partition film body can be released to the ground through the suspending metallic rope 22 and the beam 24. In this case, since the film body pieces are connected using the conductive fasteners, the static electricity charged in a certain film body piece is up to the film body piece that is in contact with or connected to the metallic rope 22,
Because it can flow through conductive fasteners,
The antistatic function can be further improved.

FIG. 3 is a diagram schematically showing a lead rope attached to the partition membrane body of the present invention or the membrane body piece thereof.

In the embodiment shown in FIG. 3, the film body 20 or the film body piece 10 is used.
An example is shown in which two lead ropes 30 and 32 are provided (hereinafter simply referred to as the film body 20). The lead ropes 30 and 32 are tubular portions 40 formed of a cloth-like member made of a cloth or an insulating material that has been subjected to an appropriate antistatic treatment,
The tube-shaped portions 40 and 42 are provided with stretched portions 44 and 46, respectively, which are attached to the tubular portions 40 and 42, respectively, and the stretched portions 44 and 46 are sewn to both sides or one side of the membrane body 20 or the like. The structure is such that they are attached using appropriate means. One lead rope 30 as shown
When the film body 20 is hung so that is separated from the floor surface, the entire film body 20 is in a suspended state in which the ropes 30 and 32 are tensioned.

On the other hand, one of the lead ropes 30 on the lower side is brought into contact with the floor surface, and the lead rope 32 on the upper side is hung down so that the film body 20 is separated from the floor surface. Although the lower film body portion is in a slackened state in which it is not tensioned, the portion of the upper film rope 20 from the upper lead rope 32 is still in a tensioned suspended state by the action of the lead rope 32.

With such a configuration, even when the film body 20 is hung down under the condition that there is an obstacle on the floor surface, even if the lower lead rope 30 comes into contact with the obstacle and the film body portion in that region is loosened, Since the lead rope 30 hangs on a floor surface without obstacles so as not to contact the floor surface, the film body portion in that area is in a tensioned hanging state. Further, as described above, in the part of the film body 20 in the region where there is an obstacle, the lead rope 32 hangs down unless the upper lead rope 32 comes into contact with the obstacle. The part is in a tensioned hanging state.

Obviously, the invention is not limited to the embodiments described above, but many variants and modifications can be made.

In the above-mentioned embodiment, the example in which the antistatic inorganic fiber is used has been described, but the present invention is not limited to this, and the non-electrostatic inorganic fiber may be used.

In the above-described embodiment, the example in which the partition film body is hung down has been described, but this partition film body is a normal covering film (sheet).
It is also suitable to use as.

Also, the shape of the membrane element that composes the partition membrane is a plane rectangle (square), but it has a planar shape that allows each membrane element to be joined with a fastener to form one partition membrane. If desired, the shape may be a triangle, a pentagon, or any other suitable shape.

Further, the lead ropes provided on the film body or the film body pieces may be provided not only at one place but also at a plurality of steps on the same film body or piece.

(Effect of the Invention) As is apparent from the above description, according to the partition film body of the present invention, the film body pieces are connected to each other by the conductive fasteners. The partition membrane unit can be assembled and configured by a simple and light work of bringing the membrane unit from the work site to the work site and fastening the film unit pieces to each other by fastener coupling.

Also, since the film element pieces are connected by the conductive fastener,
The static electricity charged on each membrane element can be easily and surely released to the ground through the metal rope attached to the membrane element, so the static electricity can be removed partially or entirely from the partition membrane element. obtain.

In addition, since the lead rope is provided on the partition membrane or membrane piece, the membrane can be tensioned and hung, and the lead rope is flexible and easily bends, thus obstructing the floor surface. Even if there is an object, only the film body in that area is slackened, and in the area where there is no obstacle, the film body can be hung with normal tension.

Because of the above-described effects, the partition membrane body of the present invention is suitable for use as an enclosure for work sites such as aircrafts, ships, and vehicles.
