Description

  The present invention relates to an apparatus for temporarily partitioning a room as needed in a factory or an office.

In general, when performing partial refurbishment work in factories, offices, etc., or when replacing some equipment in a factory, ensuring safety during the construction period, dust generated from the construction area, etc. Because of this problem, there are many temporary partitions that temporarily surround the construction area. In particular, in semiconductor and liquid crystal factories and the like where the speed of technological innovation is fast, the manufacturing equipment becomes obsolete, and therefore, it is necessary to frequently perform improvements and replacement work on the manufacturing equipment. However, in semiconductor and liquid crystal factories, for example, a set of manufacturing equipment from the previous process is often installed in a clean room all at once, so product processing is often performed. Even if it exists, it is highly necessary to perform the construction in a shielded state so that the influence of dust generation or the like by the construction does not reach other manufacturing apparatuses. Furthermore, due to the need to recover enormous amounts of investment in these semiconductor and liquid crystal factories, there is a high need to perform these constructions in a short period of time without stopping the operation of the factory as much as possible, that is, with the clean room still in operation. . Conventionally, as this type of partition, for example, a known assembling partition is known in which a rail is provided on each of the ceiling surface and the floor surface, and the partition is constructed by fitting the upper and lower edges of the panel to the rail. However, in the above-mentioned clean room, for example, the problem that it is difficult to provide rails on the ceiling surface due to an air filter or the like provided on the ceiling, or the entire system including replacement of the apparatus that requires time to install partitions There were problems such as a long construction period. For these problems, for example, a partition mechanism in a clean room of Patent Document 1 has been proposed. According to FIG. 1 of Patent Document 1, as shown in FIG. 1 of the same document, a ceiling frame 2 in which the frame material 1 is configured in a lattice shape, and a partition installed between the lattice intersection of the ceiling frame 2 and the floor. The secret curtain material 5 is attached through attachment members (6, 7) such as fasteners provided in the ceiling frame 2 and the partition pillar 4 by incorporating the pillars 4.
JP-A-10-245919

  According to Patent Document 1, since the ceiling frame 2 is provided by being suspended from the ceiling slab by the suspension bolt 9, it is necessary to separately provide a suspension means for retaining the suspension bolt 9 on the ceiling side. However, it is difficult to perform a construction in which the suspension means is provided on the ceiling while the clean room is in operation from the viewpoint of maintaining the cleanliness in the clean room. Therefore, since the use of the partition mechanism in the clean room of Patent Document 1 is limited to a clean room having a suspension means on the ceiling side in advance, there is a problem that versatility is low. In addition, according to Patent Document 1, since the mounting member such as a fastener is provided on the side surface of the partition column 4 standing between the ceiling and the floor, the height of the partition column 4 cannot be adjusted. There existed problems, such as having to prepare the partition pillar 4 of several height according to height, respectively. According to Patent Document 1, the cover member provided on the ceiling frame 2 is inverted after the ceiling frame 2 and the partition pillars 4 are assembled to expose the fastener and the like, and the confidential curtain material 5 is attached to the fastener and the like. The worker has to go up to the vicinity of the ceiling to perform the installation work, and there is a problem of the danger of working at a high place and a problem that it takes time until temporary partitioning. Further, particularly in the case of a clean room by downflow, there is a problem that the dust generation due to the reversing work in the vicinity of the ceiling and the installation work of the secret curtain material 5 has a high risk of contaminating the products underneath. In addition, according to Patent Document 1, in addition to the frame material such as the ceiling frame 2 and the partition pillars 4 and the confidential curtain material 5, a fastener for attaching the confidential curtain material 5 to the frame material is required, and the manufacturing cost is low. There was a problem of becoming higher.

The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide an indoor temporary partition device that can be reused and can be assembled and disassembled in an extremely short time at a low cost. It is in. Another object of the present invention is to provide an indoor temporary partition device that is less affected by dust generation and the like due to the mounting operation and has high versatility that is not subject to restrictions on the ceiling height and structure of the room as much as possible.

  In order to achieve the above object, the present invention is a room partition device 10 that is disposed between a floor surface (FL) and a ceiling surface (SL), and has a frame-shaped body with a shielding sheet 12 stretched thereon. The frame 14, an adjustment frame 16 that slidably engages with the main body frame 14 to extend and contract the entire length of the main body frame 14 in the vertical direction, and an arbitrary expansion / contraction engagement position between the main body frame 14 and the adjustment frame 16. A fixing mechanism 18 is provided to fix each frame against the ceiling surface and the floor surface.

At that time, the fixing mechanism 18 may be configured to include a lifting support device 20 that supports the main body frame 14 in a lifting shape with the adjustment frame 16 disposed on the lower side. The lifting support device 20 includes a long bolt 22 that vertically penetrates the main body frame 14 and the adjustment frame 16, and a nut body 24 that moves up and down along the long bolt 22 while being screwed into the long bolt 22. May be included. Further, the fixing mechanism 18 further engages the body frame 14 and the adjustment frame 16 with the main body frame 14 and the adjustment frame 16 in contact with the ceiling surface and the floor surface via the nut body 24. Fixing means 26 for fixing may be provided.

Further, a shielding sheet non-stretching portion 27 for pressing the adjustment frame side when the main body frame 14 is extended and moved upward with the adjustment frame 16 landed on the floor surface may be formed. At that time, the main body frame 14 includes left and right vertical frame members 48a and 48b spaced apart from each other in the left and right direction, and the adjustment frame 16 is slidably engaged with the left and right vertical frame members 48a and 48b. Including the members 58a and 58b, the left and right vertical frame members 48a and 48b of the main body frame 14 are sandwiched between the lower ends of the left and right vertical frame members 48a and 48b at the required height from the floor (FL) at the slide lower limit position. The partial gap 28 may be used as the shielding sheet non-stretching portion 27. Further, the main body frame 14 may have a configuration in which a lower horizontal frame member 50b is provided horizontally on the left and right vertical frame members 48a and 48b so as to be the upper limit position of the gap 28.

Further, a buffer member 29 that abuts the ceiling surface (SL) may be provided on the upper end side of the main body frame 14, and the ventilation mechanism 30 and the illumination between the frame member itself of the main body frame 14 or the adjustment frame 16 or between the frame members. Any one of the mechanism 32 and the air filter 34 or a plurality of them may be installed. Further, a concave portion 36 corresponding to the shape of the protrusion from the ceiling surface may be formed on the upper end side of the main body frame 14, and the main body frame 14 and the adjustment frame 16 may be formed in a planar view arc shape 38.

Moreover, it is good also as the temporary partition partition apparatus 42 of the structure which made the partition possible to enter / exit combining the indoor temporary partition apparatus (10) in any one of Claim 1 thru | or 11, and the frame 40 with a door.

  The indoor temporary partition device (hereinafter referred to as “device”) of the present invention is an indoor partition device disposed between the floor surface and the ceiling surface, and a frame-shaped main body frame in which a shielding sheet is stretched, An adjustment frame that slidably engages with the main body frame and expands and contracts the entire length of the main body frame in the vertical direction, and each frame at the arbitrary expansion / contraction engagement position between the main body frame and the adjustment frame. For example, even if the indoor ceiling height varies depending on the factory or the like, the device can be expanded and contracted in the vertical direction. Therefore, the apparatus can be temporarily set up without being restricted by the ceiling height in the room. In addition, since the main body frame and the adjustment frame are slidably engaged, it is possible to easily adjust the total length of the device and remove the adjustment frame from the main body frame by sliding the main body frame and the adjustment frame. The assembly / disassembly time of the apparatus can be shortened. In addition, since the shielding sheet is stretched on the frame-shaped body frame, for example, when the shielding sheet is broken or contaminated, and cannot be used in a clean room, the shielding sheet is not used. The device can be reused by replacing it with. Furthermore, since a fixing mechanism is provided for abutting and fixing each frame against the floor surface and the ceiling surface at an arbitrary expansion / contraction engagement position between the main body frame and the adjustment frame, for example, as in Patent Document 1, the ceiling is provided. Since there is no need to provide a suspension means on the surface or to attach the close curtain material 5 to the ceiling frame 2, there is little risk of dust generation near the ceiling, and the apparatus can be temporarily installed in a short time. .

  In addition, the fixing mechanism is composed of a lifting support device that supports the main body frame in a lifted state with the adjustment frame disposed on the lower side. For example, the adjustment frame is placed on the floor surface and the main body frame is placed on the floor. Since the main body frame can be supported while adjusting the total length of the apparatus to be the ceiling height by sliding it upward with the lifting support apparatus, the height of the apparatus can be easily adjusted and temporary installation can be performed quickly.

  Further, the lifting support device includes a long bolt that vertically penetrates the main body frame and the adjustment frame, and a nut body that moves up and down along the long bolt while being screwed to the long bolt. The main body frame can be moved up and down by a simple operation of bringing the nut body into contact with the lower surface of the main body frame and rotating the nut body up and down while being screwed into the long bolt. Further, the structure of the lifting support device can be simplified and the number of parts can be reduced, and the cost of the device can be reduced.

  Further, the fixing mechanism is provided with a fixing means for fixing the engagement portion between the main body frame and the adjustment frame in a state where the main body frame and the adjustment frame are abutted against the ceiling surface and the floor surface via the nut body. Therefore, the engagement between the main body frame and the adjustment frame is strengthened, and the rigidity of the entire apparatus is increased. Further, if the engagement portion between the main body frame and the adjustment frame is fixed by the fixing means, the main body frame does not fall, so that the long bolt body is not necessary. It is also possible to install a filter or the like between the frame members of the adjustment frame, and the apparatus can be multi-functionalized.

  When the adjustment frame is landed on the floor surface, when the main body frame is extended and moved upward, the shield sheet non-stretching part for pressing the adjustment frame side is formed. In a state where it is landed on the surface, for example, a foot can be inserted from the non-stretching portion of the shielding sheet, and the adjustment frame side can be pressed and held with both hands of the main body frame and extended upward. Therefore, the main body frame 14 can be quickly brought into contact with the ceiling surface (FL), and the temporary construction of the room partition device according to the present invention can be performed in a very short time.

  The main body frame includes left and right vertical frame members that are spaced apart from each other in the left and right direction, and the adjustment frame includes left and right slide frame members that are slidably engaged with the left and right vertical frame members. Since the gap between the lower end sides of the left and right vertical frame members is the required height from the floor surface at the lower slide slide position, the shielding sheet is not stretched, so the adjustment frame is landed on the floor surface. In this state, for example, an operation of inserting the foot from the non-stretching portion of the shielding sheet and holding the adjustment frame side and holding it with both hands of the main body frame and extending it upward can be realized. Temporary work can be shortened effectively.

  Since the main body frame has a configuration in which a lower horizontal frame member is provided horizontally on the left and right vertical frame members so as to be the upper limit position of the gap, for example, only the upper main body frame portion is shielded from the lower horizontal frame member. If the sheet is stretched, a shielding sheet non-stretching portion having a gap between the lower end sides of the left and right vertical frame members can be reliably formed at a required height from the floor surface. Therefore, the temporary construction of the room partition device of the present invention by the shielding sheet non-stretching portion can be shortened. In addition, after the indoor temporary partition device of the present invention is erected, the shielding sheet can be quickly stretched using the lower side of the lower horizontal frame member and the left and right vertical frame members.

  In addition, since the buffer member that abuts the ceiling surface is provided on the upper end side of the main body frame, for example, by using an elastic body or the like as the buffer material, the device is placed between the floor surface and the ceiling surface. The upper end of the main body frame can be pressed against the ceiling surface via the elastic body when standing up, and the stability of the standing state can be enhanced. In addition, since the apparatus abuts against the ceiling surface via the cushioning material, the main body frame does not directly abut against the air filter or the like disposed on the ceiling surface, for example, and is not damaged.

  In addition, since the frame member itself of the main body frame or the adjustment frame or the ventilation mechanism, the illumination mechanism, the air filter or a plurality of them is installed between the frame members, for example, ventilation of the partitioned area, The apparatus can be used as needed for lighting or air purification, and convenience is enhanced.

  In addition, since the concave portion corresponding to the shape of the protrusion from the ceiling surface is formed on the upper end side of the main body frame, for example, when the lighting fixture protrudes from the ceiling surface, the upper end side of the main body frame Since partitioning is possible using a device in which a recess corresponding to the shape of the lighting fixture is formed, a highly versatile device that is not restricted by the shape of the ceiling surface or the like can be provided.

  In addition, since the main body frame and the adjustment frame are formed in an arc shape in plan view, for example, the apparatus can be temporarily installed so that the partition surface has a curved surface shape according to the layout of the partition part in the room. Increases nature.

  Since the temporary partitioning device in the room according to any one of claims 1 to 10 and a frame with a door can be combined to make a temporary partitioning device capable of entering and exiting the partition, for example, a corner without a door When the partition is temporarily installed in a partition, etc., the combination of the device and the removable temporary partition device allows a person to enter the partition area via the removable temporary partition device as necessary. Rise.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. The apparatus of the present invention is an indoor temporary partition device that can be temporarily installed between the floor surface and the ceiling surface in an extremely short time while extending and contracting its entire length in the vertical direction. As shown in FIGS. 1 to 5, the indoor partition device 10 a in this embodiment includes a shielding sheet 12, a main body frame 14, an adjustment frame 16, a shielding sheet non-stretching portion 27, a fixing mechanism 18, Buffer member 29.

In the present embodiment, the main body frame 14 is a frame means for stretching a shielding sheet 12 described later as a partition surface, and includes left and right vertical frame members 48a and 48b, upper and lower horizontal frame members 50a and 50b, and a reinforcing member. 46a, 46b, and is formed in a rectangular frame shape. In the present embodiment, each of these members (48, 50, 46) is formed of a hollow rectangular bar member. Specifically, the left and right vertical frame members 48a and 48b have, for example, a length of about 2.5 m and a rectangular hollow cross section of about 3 cm × 5 cm, as shown in FIGS. It is formed of an open hollow square bar member, and is arranged separately on the left and right sides with the side surfaces corresponding to the short sides of the rectangular cross section facing each other. Next, the upper and lower horizontal frame members 50a and 50b have the same cross-sectional shape as the vertical frame member 48, and are each formed of, for example, a hollow square bar member having a length of about 90 cm, and correspond to the short side of the rectangular cross section. The side surfaces are opposed to each other and spaced apart from each other. As shown in FIGS. 1 and 2, the upper ends of the left and right vertical frame members 48 are connected by an upper horizontal frame member 50a. In addition, a lower horizontal frame member 50b is provided horizontally on the left and right vertical frame members 48a and 48b at the upper limit position of the shielding sheet non-stretching portion 27 described later, and the main body frame 14 is formed in a rectangular shape when viewed from the front. The At this time, since the left and right vertical frame members 48a and 48b and the upper and lower horizontal frame members 50a and 50b have the same rectangular cross-sectional shape, as shown in FIGS. The frame members (48, 50) can be connected so as to form a flat surface along the side surface on the long side in sectional view, and the flat surface forms the stretched surface 52. Therefore, since the shielding sheet 12 to be described later can be stretched in close contact with the stretched surface 52, the shielding effect is enhanced, which is particularly effective in a clean room or the like. Next, as shown in FIGS. 1 and 2, reinforcing members 46a and 46b having substantially the same shape and dimensions as the upper and lower horizontal frame members 50a and 50b are provided horizontally on the left and right vertical frame members 48a and 48b. 14 is reinforced. The main body frame 14 is erected on the floor surface with lower ends supported by an adjustment frame 16 and a lifting support device 20 described later. In the present embodiment, the vertical frame member 48 and the horizontal frame member 50 are formed of a hollow aluminum material, but may be formed of steel or synthetic resin, not limited to the dimensions of the present embodiment, It can be set to any size as required. Further, the cross-sectional shape may be formed in a convex shape, for example, as long as it can be slidably engaged with an adjustment frame 16 described later.

In this embodiment, the shielding sheet 12 is a shielding means that is stretched around the main body frame 14 and shields the inside and outside of the partition area, and is formed of a rectangular sheet. Specifically, as shown in FIG. 1 to FIG. 5, it has substantially the same width as the main body frame 14 and a vertical side with a length of about the upper horizontal frame member 50a to the lower horizontal frame member 50b, for example, several tens of μm. It is formed of a rectangular polyethylene sheet having a thickness of about 100 μm. And it is stretched on the stretched surface 52 of the main body frame described above via, for example, a known double-sided adhesive tape (not shown). In addition, when the shield sheet once stretched cannot be reused in a clean room or the like due to, for example, breakage or contamination, the apparatus can be reused by replacing the shield sheet with an unused shield sheet. The shielding sheet is not limited to polyethylene, but may be made of synthetic resin such as polyester, or may have a thickness as required. In addition, in order to prevent, for example, destruction of the semiconductor element due to charging of the shielding sheet, a conductive treatment such as covering the shielding sheet with a known conductive polymer may be performed.

In the present embodiment, the adjustment frame 16 is a body frame support means for slidably engaging with the body frame 14 to support the body frame 14, and as shown in FIGS. 1 and 2, left and right slide frame members 58a and 58b. The bottom frame member 60 is formed in a U-shape when viewed from the front. Specifically, the left and right slide frame members 58a and 58b are substantially the same length as the vertical frame member 48 described above, and have a substantially square cross section made of a side slightly shorter than the short side of the rectangular cross section of the vertical frame members 48a and 48b. It is formed of a hollow square bar member having dimensions, and is inserted into the hollow portions of the vertical frame members 48a and 48b. Further, the bottom frame member 60 is formed of a hollow rectangular bar member having the same cross section as the slide frame member 58 and substantially the same length as the above-described horizontal frame member 50. As shown in FIGS. 1 and 2, the bottom frame member 60 is connected to the lower end portions of the left and right slide frame members 58 a and 58 b in a substantially U shape when viewed from the front. 2 and 3, the slide frame members 58a and 58b of the adjustment frame 16 are inserted from the open lower ends of the left and right vertical frame members 48a and 48b of the main body frame 14, respectively. Are engaged in a slide shape, the slide frame member 58 is guided by the inner wall surface of the vertical frame member 48, and the entire length of the apparatus can be expanded and contracted in the vertical direction in a slidable manner. In the present embodiment, the slide frame member 58 and the bottom frame member 60 are formed of an aluminum hollow mold material, but may be formed of steel or synthetic resin, and may have arbitrary dimensions as required. be able to. Further, the cross-sectional shape of the slide frame member 58 may be formed in, for example, a concave shape as long as it can be slidably engaged with the main body frame 14 described above. Further, a shielding sheet may be stretched on the adjustment frame 16 as necessary. As described above, since the apparatus 10a is formed by combining the rectangular frame that is the main body frame 14 and the U-shaped frame that is the adjustment frame 16, a thin shielding sheet is formed on these frames. Even if 12 is stretched, it is extremely light compared to a known partition plate or the like, and can be easily transported or lifted. In particular, the main body frame 14 and the adjustment frame 16 include an outer shape frame made of an elongated metal plate, a bar, a pipe material, and the like, and a partition shielding body in a space in which a film-like shielding sheet is stretched in the inner space. Since it is configured, it has advantages such as weight reduction of the apparatus, ease of transportation, and ease of assembly / disassembly work.

In the present embodiment, the shielding sheet non-extending portion 27 is a pressing operation assisting means for pressing the adjustment frame when the main body frame 14 is extended upward while the adjustment frame 16 is landed on the floor surface. The lower horizontal frame member 50b, the left and right vertical frame members 48a and 48b, and the bottom frame member 60 are formed. As shown in FIGS. 1 and 5, the lower horizontal frame member 50 b is the same as the lower horizontal frame member 50 b described above, and from the floor (FL) at the slide lower limit position of the left and right vertical frame members 48 a and 48 b of the main body frame 14. For example, it is formed so as to be horizontally placed between the lower end sides of the left and right vertical frame members 48a and 48b at a height of about the instep. The left and right vertical frame members 48a and 48b and the bottom frame member 60 are the same as those described above, and a description thereof will be omitted. As shown in FIGS. 1 and 5, the shielding sheet non-extending portion 27 is a rectangle surrounded by the lower horizontal frame member 50 b, the lower ends of the left and right vertical frame members 48 a and 48 b, and the bottom frame member 60. Formed as a void. Accordingly, it is possible to lift the main body frame with both hands while inserting the foot from the shielding sheet non-extending portion 27 and fixing the device 10a in a state where the bottom frame member 60 of the adjustment frame 16 described later is stepped on the sole of the foot. Therefore, it is possible to easily perform the operation of adjusting the overall length of the apparatus and bringing the apparatus head into contact with the ceiling surface. After the apparatus 10a is fixed upright, the shielding sheet is quickly stretched using the lower horizontal frame member 50b and the lower end side of the left and right vertical frame members 48a and 48b or the left and right slide frame members 58a and 58b of the adjustment frame 16. Can be set. The height of the lower horizontal frame member 50b from the floor surface is not limited to the height of the present embodiment, and may be a required height as required.

In the present embodiment, the fixing mechanism 18 is an upright fixing means for fixing the device 10a upright between the indoor floor surface (FL) and the ceiling surface (SL). And fixing means 26. In the present embodiment, as shown in FIG. 2, the lifting support device 20 is a support means for the main body frame 14 that supports the main body frame 14 in a lifted state with the adjustment frame 16 disposed on the lower side. 22 and a nut body 24. In this embodiment, as shown in FIGS. 2 to 4, the long bolt 22 is, for example, a screw extending over the entire outer circumference of a cylindrical bar having a diameter of about 1.5 cm and a length of about 1.5 m. It is formed by cutting. As shown in FIGS. 2, 3, and 5, the long bolt 22 has its lower end abutted against the center of the bottom frame member 60 of the adjustment frame 16, and its upper end is the lower horizontal frame member of the main body frame 14. It is suspended from the bottom frame member 60 in a state of being penetrated through the through hole 25 opened at the center of 50b. Next, the nut body 24 of the present embodiment is formed of a nut member such as a wing nut that is screwed into the long bolt 22. As shown in FIGS. 2 and 3, the long bolt 22 is screwed at a position below the lower horizontal frame member 50 b of the main body frame 14. Therefore, if the nut body 24 is moved upward and brought into contact with the lower end surface of the lower horizontal frame member 50b, the lowering of the main body frame 14 can be restricted, and the main body frame 14 is supported in a lifting shape. Further, if the nut body 24 is rotated and moved in the vertical direction, the main body frame 14 can be moved up and down via the lower horizontal frame member 50b, so that any expansion / contraction engagement between the main body frame 14 and the adjustment frame 16 can be achieved. At the position, each frame can be fixed by abutting against the floor surface (FL) and the ceiling surface (SL). Moreover, the adjustment at the time of abutting the partition main body frame 14 against the ceiling surface can be easily performed, and the temporary construction is facilitated. Further, in the present embodiment, the lifting support device 20 includes the long bolt 22 and the nut body 24. Therefore, the number of parts is small, the structure can be simplified, and the cost can be reduced. Further, the long bolt 22 is not limited to the length of the present embodiment, and the reinforcing member 46 may be penetrated as necessary, for example, to have a substantially full length of the device 10a. Moreover, it is not limited to a pair of long bolts and nut bodies, and may be formed from a plurality of pairs.

In the present embodiment, the fixing means 26 is a connection fixing means for connecting and fixing the main body frame 14 and the adjustment frame 16, and includes a vertical frame member 48, a slide frame member 58, male screw members 62 and 62, and a female screw. Members 64, 64. In the present embodiment, the vertical frame member 48 and the slide frame member 58 are the same as those described above, and a description thereof will be omitted. Next, as shown in FIGS. 1 to 3, the male screw members 62, 62 are the opposite side surfaces of the left and right vertical frame members 48 a, 48 b of the main body frame 14, and are the lower horizontal frame members of the main body frame 14. Left and right are provided at intermediate positions between 50b and the lower end of the vertical frame member 48, respectively. Specifically, as shown in FIG. 3, male screw members 62 and 62 having threaded portions having substantially the same length as the long sides of the rectangular cross section of the vertical frame member 48 are arranged so that the longitudinal direction thereof is horizontal to the floor surface. In addition, the left and right vertical frame members 48, 48 are provided so as to penetrate the hollow side perpendicular to the opposing side surfaces. The female screw members 64 and 64 are fixed to the opposite side surfaces of the left and right vertical frame members 48a and 48b at positions where they are screwed with the male screw members 62 and 62, respectively. Therefore, with the main body frame 14 and the adjustment frame 16 in the sliding engagement state, the male screw member 62 is screwed into the hollow cross section of the vertical frame members 48a and 48b, and the slide frame members 58a and 58b are connected to the vertical frame member 48a, If it press-contacts to the inner wall surfaces 68a and 68b of 48b, sliding friction will increase and the engaging part of the main body frame 14 and the adjustment frame 16 will be fixed. Therefore, the engagement between the main body frame 14 and the adjustment frame 16 is strengthened, and the rigidity of the entire apparatus is increased. Further, if the engagement portion between the main body frame 14 and the adjustment frame 16 is fixed by the fixing means 26, the main body frame 14 will not fall, so the long bolt 22 is not necessary. For example, the long bolt 22 is removed. Thus, an air filter 34 and the like which will be described later can be installed between the frame members of the adjustment frame 16.

In the present embodiment, the buffer member 29 is a pressure contact portion that presses the device 10 a against the ceiling surface (SL), and is formed by providing the thin plate elastic body 70 on the upper end surface of the main body frame 14. Specifically, as shown in FIGS. 1 and 2, a thin plate elastic body 70 that is substantially the same as the upper end surface is attached to the upper end surface of the upper horizontal frame member 50 b of the main body frame 14 via, for example, a double-sided adhesive sheet. Provided. Accordingly, the apparatus 10a can be erected between the floor surface and the ceiling surface, and the upper end of the main body frame can be pressed against the ceiling surface via the thin elastic body 70, so that the stability of the erected state can be improved. In addition, for example, an air filter or the like disposed on the ceiling surface is not directly damaged by the main body frame. In this embodiment, the thin plate elastic body 70 is made of urethane resin, but may be made of other synthetic resin as long as it has some elasticity. Further, in a clean room or the like, for example, silicon resin or the like that is difficult to become a dust generation source may be used.

Next, the operation of the device 10a according to the present embodiment will be described with reference to FIGS. First, as shown in FIG. 1, the left and right slide frame members 58a and 58b of the adjustment frame 16 are inserted into the hollow interiors of the left and right vertical frame members 48a and 48b of the main body frame 14, respectively. Is slidably engaged. In particular, in a room having a ceiling height exceeding, for example, about 4 m, even if it is difficult to carry in a known partition plate exceeding 4 m, the apparatus 10a of the present invention is used. For example, since the main body frame 14 and the adjustment frame 16 having a length of about 2 m can be divided and loaded, the loading and assembly are facilitated. Next, as shown in FIGS. 1 and 5, for example, the shielding sheet 12 is stretched on the main body frame 14 so as to cover an area from the upper end of the main body frame 14 to the lower horizontal frame member 50 b. At this time, since the stretched surface 52 is a flat end surface, the shield sheet 12 can be stretched closely, so that the shielding effect is enhanced, which is particularly effective in a clean room or the like. In addition, when bringing a known partition plate or the like into a clean room, it is necessary to remove dust and contamination adhered to the partition plate and the like before wiping the partition plate, for example. According to the apparatus 10a, since the apparatus can be brought into the clean room without the shielding sheet 12 being stretched, such a removal work or the like is not required, and the preparation work for the temporary work can be performed in a very short time. Next, the apparatus is erected on the floor surface with the bottom frame member 60 of the adjustment frame 16 on the lower side, and the main body frame is lifted upward. At this time, as shown in FIG. 5, since the shielding sheet non-stretching portion 27 is formed on the lower end side of the main body frame 14, the shielding sheet non-stretching is performed with the adjustment frame 16 landed on the floor surface. From the portion 27, for example, a foot can be inserted and the adjustment frame side can be pressed and the main body frame 14 can be held with both hands and extended upward. Further, the main body frame 14 is extremely light since only the thin shielding sheet 12 is stretched on the frame body, and the temporary work of the apparatus 10a can be made extremely short, for example, the main body frame 14 can be quickly abutted against the ceiling surface (FL). Can be done in time. Moreover, since the main body frame 14 is lightweight, it is advantageous particularly when the main body frame 14 needs to be lifted high in a room where the ceiling height is somewhat high. Next, as shown in FIGS. 2 and 5, the frames of the main body frame 14 and the adjustment frame 16 are brought into contact with the floor surface and the ceiling surface via the fixing mechanism 18 to fix the apparatus.

At this time, since the apparatus is already supported in a lifting shape, it is not necessary to hold the main body frame 14 with both hands, and it is possible to save labor for fixing work. Further, since the engagement portion is fixed, the engagement between the main body frame 14 and the adjustment frame 16 is strengthened, the rigidity of the entire apparatus is increased, and the apparatus does not rattle after standing. Furthermore, after fixing, the long bolts 22 and the like can be removed, and for example, an air filter or the like can be installed in the adjustment frame 16. Next, as shown in FIG. 6, if the shielding sheet 13 is stretched so as to cover the lower end portion of the main body frame 14 and the adjustment frame 16, a partition surface is constructed in the entire apparatus. As described above, according to the apparatus of the present invention, there is no need to provide a suspension means or the like on the ceiling surface or to attach the close curtain material 5 to the ceiling frame 2 as in Patent Document 1, for example. The risk of dust generation near the ceiling is small, and the apparatus can be temporarily installed in a short time. Further, when the device is removed from the room, it can be easily disassembled by an operation reverse to the above description, so that the device can be removed in a very short time.
