Summary of the Invention

Problems to be Solved by the Invention

[0005] In the soundproof and dustproof structure of Patent Document 1 above, the column portions and the horizontal crossbars are formed in a frame shape. When such column portions and horizontal crossbars arranged in a frame shape are formed, it is difficult to adjust the height and width of the panel unit.

[0006] For example, Patent Document 1 above describes that when shortening the height of a panel unit, the middle position of a column portion is tied with a string. However, there is a possibility that the horizontal bars in the portion where air is not sent, and the flexible sheets attached to these horizontal bars and columns may overlap, making it difficult to ensure airtightness. That is, it is difficult to adjust the height and width while ensuring airtightness.

[0007] Therefore, in Patent Document 2 above, airtightness is ensured by sandwiching a sheet between a column member and a floor surface or the like, and the height and width of the partition are adjusted by winding up the column member and the beam member. However, considering the efficiency of transportation work, there is room for improvement from the perspective of weight reduction.

[0008] In view of the above facts, an object of the present invention is to provide a portable partition that is easy to transport.

Means for Solving the Problems

[0009] The portable partition according to claim 1 includes two column members formed of a flexible film body filled with air inside, a beam member formed of a flexible film body whose inside communicates with the inside of the column member, and both ends of which are respectively connected to the upper end portions of the column members, and a sheet that is detachably joined to the column members and the beam member and can suppress the scattering of dust.

[0010] The portable partition according to claim 1 is formed of a film body column member, a beam member, and a sheet. The column member and the beam member are formed by filling air inside. Therefore, it is lighter and easier to carry than a partition formed by attaching a sheet to a steel scaffold or the like. Also, by adjusting the air pressure, it can be stretched and held between the ceiling and the floor, so installation is easy. Furthermore, it can be easily carried by releasing the air.

[0011] Also, both ends of the beam member are connected to the upper end portions of the column members. Therefore, it can be made lighter compared to the configuration of a portable partition in which the beam member protrudes horizontally from the column members arranged at the same interval as in this aspect and is cantilevered. For this reason, it is easy to transport.

[0012] The portable partition according to claim 2 includes: one column member formed of a flexible film body filled with air inside; a beam member formed of a flexible film body whose interior communicates with the interior of the column member, and having the upper end portion of the column member connected to the central portion in the longitudinal direction; and a sheet detachably joined to the column member and the beam member and capable of suppressing the scattering of dust.

[0013] The portable partition according to claim 2 is formed of a column member, a beam member, and a sheet of a film body. The column member and the beam member are formed by filling air inside. Therefore, it is lighter and easier to carry than a partition formed by attaching a sheet to a steel scaffold or the like. Also, by adjusting the air pressure, it can be stretched and held between the ceiling and the floor, so the installation is easy. Furthermore, it can be easily carried by releasing the air.

[0014] Also, the column member is formed of one piece. Therefore, the weight can be reduced compared to the configuration of a portable partition provided with two column members. Thus, it is easy to transport.

[0015] The portable partition according to claim 3 is the portable partition according to claim 1 or 2, wherein the column member is provided with a diaphragm that partitions the interior of the space in which the column member and the beam member communicate into a plurality of spaces.

[0016] The portable partition according to claim 3 is provided with a diaphragm that partitions the interior into a plurality of spaces. By partitioning the interior of the column member into a plurality of spaces in this way, air can be filled into each space separately.

[0017] The speed at which air can be filled into any one of the partitioned spaces is faster than the speed at which air is filled into the non-partitioned column member at one time. Therefore, first, only the space in the lower part of the column member can be filled with air.

[0018] Then, if the portable partition is transported to the installation position, the column member is positioned, and then the upper part is filled with air, the startup of the portable partition can be smoothly carried out.

[0019] The portable partition according to claim 4 is the portable partition according to claim 1 or 2, wherein a plurality of air jacks capable of lifting the column member are vertically stacked and mounted at the lower end of the column member.

[0020] In the portable partition according to claim 4, air jacks are vertically stacked and mounted at the lower end of the column member. Therefore, the height of the column member can be adjusted. In addition, compared with the case where there is only one air jack, the adjustment cost of the height of the column member is large. Thereby, the scattering of dust can be suppressed in buildings with various ceiling heights.

[0021] The portable partition according to claim 4 may be the portable partition according to any one of claims 1 to 3, wherein a plurality of air jacks capable of lifting the column member are vertically stacked and mounted at the lower end of the column member.

[0022] The portable partition according to claim 5 is the portable partition according to claim 1 or 2, wherein a surface fastener capable of joining the sheet is fixed to the upper surface of the beam member.

[0023] In the portable partition according to claim 5, a surface fastener capable of joining the sheet is fixed to the upper surface of the beam member. Thereby, the sheet can be sandwiched and fixed between the beam member and the ceiling surface, so the effect of suppressing dust scattering is great.

[0024] The portable partition according to claim 5 may be the portable partition according to any one of claims 1 to 4, wherein a surface fastener capable of joining the sheet is fixed to the upper surface of the beam member.

Advantages of the Invention

[0025] According to the portable partition of the present invention, it is easy to carry.

[0030] <Portable partition 1> FIG. 1 shows a portable partition (hereinafter referred to as a partition) 10A according to an embodiment of the present invention. The partition 10A is a curing wall for suppressing the scattering of dust accompanying demolition over a wide range in building demolition work or the like. Further, the partition 10A can also be used for suppressing the scattering of paint in painting work or the like. The partition 10A is formed including a sheet 20A and an air body 30A.

[0031] (Sheet) Sheet 20A is formed in a rectangular shape with a width W1 (for example, W1 = 2100 [mm]) and a height H1 (for example, H1 = 2940 [mm]). Sheet 20A is made of, for example, vinyl chloride and is a film body capable of suppressing the scattering of dust.

[0032] Fastener G is fixed to sheet 20A. Note that fastener G is a joining material used by bonding a hook-shaped surface fastener (male fastener) and a loop-shaped surface fastener (female fastener) to each other. These surface fasteners can be detachably bonded.

[0033] In the following description, without specifying the types of the two types of surface fasteners, namely the hook-shaped surface fastener and the loop-shaped surface fastener, these are described as fastener G.

[0034] The fasteners G that are bonded to each other are, respectively, one is a hook-shaped surface fastener and the other is a loop-shaped surface fastener. In the following description, a pair of fasteners bonded to each other may also be referred to as fastener G.

[0035] On one surface of sheet 20A, fastener G is fixed along both end sides and the upper end side in the width direction of sheet 20A. Also, fastener G is fixed at a position corresponding to the fastener G fixed to air body 30A. Fastener G can also be fixed to the other surface of sheet 20A.

[0036] (Air body) Air body 30A is a bag-shaped structure formed of a flexible film body filled with air inside. Air body 30A includes column member 32, beam member 34, and connection reinforcement member 36. These column member 32, beam member 34, and connection reinforcement member 36 are connected in a state of communicating with each other as shown below, and air is allowed to flow through.

[0037] In addition, as the flexible material for forming the air body 30A, various materials such as knitted fabrics, woven fabrics, and non-woven fabrics made of polyester or the like, with both sides or one side of the fiber base material coated with polyvinyl chloride, rubber, etc., such as tarpaulin, PVC (polyvinyl chloride), PP (polypropylene), CSM (chlorosulfonated polyethylene), can be used.

[0038] The column member 32 is a long member formed in a cylindrical shape (circular column shape) with a diameter of about 180 [mm], and two column members 32 are provided in the air body 30A of this embodiment. The column member 32 has a height H4 (for example, H4 = 2400 [mm]).

[0039] Note that the height H4 is the dimension when the pressure of the air filled inside the air body 30A is equal to the atmospheric pressure in a state where no external force is applied. Also, the height H4 is the dimension in a state where the film body forming the air body 30A is not elastically deformed. The same applies to various dimensions regarding the air body 30A shown below.

[0040] A handle 32E is formed on each column member 32. The handles 32E are provided at opposing portions of the adjacent column members 32.

[0041] The beam member 34 is a long member formed in a cylindrical shape (circular column shape) with a diameter of about 180 [mm], and both ends are connected to the upper ends of the column members 32 respectively. The beam member 34 has a length W2 (for example, W2 = 1800 [mm]).

[0042] The connection reinforcement member 36 is a long member formed in a cylindrical shape (circular column shape), and both ends are connected to the column members 32 respectively. The connection reinforcement member 36 is provided such that its lower end is disposed at a position of height H6 (for example, H6 = 1000 [mm]) from the lower end of the column member 32.

[0043] (Diaphragm) The column member 32 is provided with a diaphragm 32P that divides the interior of the space where the column member 32 and the beam member 34 communicate into a plurality of spaces. By this diaphragm 32P, the interior of the air body 30A is divided into two spaces.

[0044] The two spaces are 1: the space extending over the upper part of the two column members 32 and the beam member 34 2: the space extending over the lower part of the two column members 32 and the connecting and reinforcing member 36 That is. The air body 30A is provided with valves 32V for introducing air into each of these spaces.

[0045] The position where the diaphragm 32P is provided is not particularly limited. As an example, it is preferably provided at a position from 1 / 2 to 2 / 3 of the length of the column member 32 from the lower end of the column member 32. The diaphragm 32P may be provided at the longitudinal center of the column member 32 (the position of 1 / 2 of the length of the column member 32 from the lower end of the column member 32), or slightly above the longitudinal center of the column member 32 (the position of 1 / 2 of the length of the column member 32 from the lower end of the column member 32). Further, it is preferably provided above the handle 32E and the connecting and reinforcing member 36.

[0046] If the diaphragm 32P is provided at a position of 1 / 2 or more of the length of the column member 32 from the lower end of the column member 32, when filling the upper part with air after filling the lower part of the partitioned space with air, the lower part is stable and the filling work is easy when filling the upper part with air. Also, it is easy to transport the air body 30A before filling the upper part with air.

[0047] Fasteners G are fixed to the column member 32 and the beam member 34 along their respective axial directions. The fastener G is fixed to the surface facing the sheet 20A. By attaching the fastener G to the fastener G of the sheet 20A, the partition 10A is formed.

[0048] The sheet 20A can be attached and detached along the longitudinal direction of the column member 32 and the beam member 34 by attaching or detaching the fastener G. Note that the fasteners G at the ends of the column member 32 and the beam member 34 will be described later.

[0049] <Portable partition 2> FIG. 2 shows a portable partition (hereinafter referred to as a partition) 10B according to an embodiment of the present invention. The partition 10B is a curing wall for suppressing the wide - spread scattering of dust accompanying demolition in building demolition work and the like. Further, the partition 10B can also be used for suppressing the scattering of paint in painting work and the like. The partition 10B is formed including a sheet 20B and an air body 30B.

[0050] (Sheet) The sheet 20B is formed in a rectangular shape with a width W1 (for example, W1 = 2100 [mm]) and a height H1 (for example, H1 = 2940 [mm]). The sheet 20B is made of, for example, vinyl chloride and is a film body capable of suppressing the scattering of dust.

[0051] On one surface of the sheet 20B, fasteners G are fixed along both end sides and the upper end side in the width direction of the sheet 20B. Further, the fasteners G are also fixed at positions corresponding to the fasteners G fixed to the air body 30B. The fasteners G can also be fixed to the other surface of the sheet 20B.

[0052] (Air body) The air body 30B is a bag - shaped structure formed of a flexible film body filled with air inside. The air body 30B includes column members 32 and beam members 34. These column members 32 and beam members 34 are connected in a state of communicating with each other as shown below, and air is allowed to flow through.

[0053] As the flexible material forming the air body 30B, various materials such as tarpaulin obtained by coating both sides or one side of a fiber base material such as knitted fabric, woven fabric, or non-woven fabric made of polyester or the like with polyvinyl chloride or rubber, PVC (polyvinyl chloride), PP (polypropylene), CSM (chlorosulfonated polyethylene), etc. can be used.

[0054] The column member 32 is a long member formed in a cylindrical shape (columnar shape) with a diameter of about 180 [mm], and one such column member 32 is provided in the air body 30B of the present embodiment. The column member 32 has a height H4 (for example, H4 = 2400 [mm]).

[0055] Note that the height H4 is the dimension when the pressure of the air filled inside the air body 30B is equal to the atmospheric pressure in a state where no external force is applied. Also, the height H4 is the dimension in a state where the film body forming the air body 30B is not elastically deformed. The same applies to various dimensions regarding the air body 30B shown below.

[0056] A handle 32E is formed on the column member 32. The handle 32E is provided on the side surface opposite to the side fixed to the seat 20B.

[0057] The beam member 34 is a long member formed in a cylindrical shape (columnar shape) with a diameter of about 180 [mm], and the central portion in the longitudinal direction is connected to the upper end portion of the column member 32. The beam member 34 has a length W2 (for example, W2 = 1800 [mm]).

[0058] (Diaphragm) A diaphragm 32P that partitions the inside of the space where the column member 32 and the beam member 34 communicate into a plurality of spaces is provided in the column member 32. By this diaphragm 32P, the inside of the air body 30B is partitioned into two spaces.

[0059] The two spaces are 1: The space extending over the upper portion of the column member 32 and the beam member 34 2: The space in the lower portion of the column member 32 It is so. The air body 30B is provided with a valve 32V for introducing air into each of these spaces.

[0060] The position where the diaphragm 32P is provided is not particularly limited. As an example, it is preferably provided at a position from the lower end of the column member 32 to 1 / 2 to 2 / 3 of the length of the column member 32. The diaphragm 32P may be provided at the longitudinal center of the column member 32 (the position at 1 / 2 of the length of the column member 32 from the lower end of the column member 32), or slightly above the longitudinal center of the column member 32 (the position at 1 / 2 of the length of the column member 32 from the lower end of the column member 32). Also, it is preferably provided above the handle 32E.

[0061] If the diaphragm 32P is provided at a position of 1 / 2 or more of the length of the column member 32 from the lower end of the column member 32, when filling the upper part with air after filling the lower part of the partitioned space with air, the lower part is stable and the filling operation is easy when filling the upper part with air. Also, it is easy to transport the air body 30A before filling the upper part with air.

[0062] Fasteners G are fixed along the respective axial directions of the column member 32 and the beam member 34. The fastener G is fixed to the surface facing the sheet 20A. By bonding the fastener G to the fastener G of the sheet 20B, the partition 10B is formed. The sheet 20A can be attached and detached along the longitudinal direction of the column member 32 and the beam member 34 by bonding or peeling the fastener G. Note that the fasteners G at the ends of the column member 32 and the beam member 34 will be described later.

[0063] <Retention member 1> In the air body 30A shown in FIG. 1 and the air body 30B shown in FIG. 2, the lower end of the column member 32 can be inserted into the retention member 40A and used. The retention member 40A is a bottomed member formed in a cylindrical shape (columnar shape) with a diameter of about 190 [mm]. An air jack 60, which will be described later, is mounted vertically on the lower end surface of the retention member 40A.

[0064] FIG. 3 shows an example in which the length of the column member 32 in the air body 30A is adjusted using the holding member 40A. Similarly, FIG. 4 also shows an example in which the length of the column member 32 in the air body 30B is adjusted using the holding member 40A.

[0065] As shown in FIGS. 1 and 2, a fastener G is fixed to the lower end portions of the column members 32 in the air bodies 30A and 30B. This fastener G is fixed to four surfaces along the axial direction of the column member 32. Specifically, the four surfaces are the surface facing the sheet 20A or 20B, the surface opposite to this surface, and two surfaces intersecting these surfaces at approximately 90°.

[0066] On the other hand, in a cap-shaped holding member 40A formed in a bottomed cylindrical shape, a fastener G is fixed to the inner peripheral surface. This fastener G is fixed along the circumferential direction of the inner peripheral surface of the holding member 40A.

[0067] As shown in FIGS. 5(A) to 5(D), the lower end portion of the column member 32 can be inserted into the holding member 40A in a state where the lower end portion of the column member 32 is folded inward so that the inner peripheral surfaces of the column members 32 are in contact with each other.

[0068] The lower end portion of the column member 32 is closed as shown in FIG. 5(A) so that the air inside the air bodies 30A and 30B does not leak to the outside. Therefore, as shown in FIG. 5(B), by folding the closed lower end portion inside the column member 32, the length of the column member 32 can be changed while maintaining a state where air does not leak to the outside.

[0069] Note that since the amount of air that can be filled into the air bodies 30A and 30B changes due to the folding, it is preferable to perform the folding before completely filling the air bodies 30A and 30B with air. Also, it is preferable to insert the column member 32 into the holding member 40 with the air jack 60 unfilled or not completely filled with air.

[0070] Then, as shown in Fig. 5(C), by inserting the lower end portion of the column member 32 into the holding member 40 in a state where the inner peripheral surfaces of the column members 32 are folded inward so as to contact each other, a state in which the length of the column member 32 is shortened can be maintained.

[0071] Then, the air bodies 30A or 30B are arranged between the floor and the ceiling, and a compressor hose (not shown) or the like is connected to the air jack 60 to fill it with air as shown in Fig. 5(D). Thereby, the air bodies 30A and 30B can be held in a state of being stretched between the floor and the ceiling.

[0072] <Holding member 2> In the air body 30B shown in Fig. 2, the end portion of the beam member 34 can be inserted into and used with the holding member 40B. The holding member 40B is a bottomed member formed in a cylindrical shape (circular column shape) with a diameter of about 190 [mm].

[0073] Fig. 4 shows an example in which the length of the beam member 34 in the air body 30B is adjusted using the holding member 40B. Similarly, Fig. 4 also shows an example in which the length of the column member 32 in the air body 30B is adjusted using the holding member 40A.

[0074] Fasteners G are fixed to both end portions of the beam member 34. These fasteners G are fixed to four surfaces along the axial direction of the beam member 34. Specifically, the four surfaces are the surface facing the sheet 20A or 20B, the surface on the opposite side of this surface, and two surfaces that intersect these surfaces at approximately 90°.

[0075] On the other hand, on the inner peripheral surface of the cap-shaped holding member 40B formed in a bottomed cylindrical shape, a fastener G is fixed. This fastener G is fixed along the circumferential direction of the inner peripheral surface of the holding member 40B. Also, fasteners G are fixed to the end surface and the outer peripheral surface of the holding member 40B.

[0076] Similarly to the lower end portion of the column member 32, the end portion of the beam member 34 can also be inserted into the holding member 40B in a state where the inner peripheral surfaces of the beam members 34 are folded inward so as to contact each other.

[0077] <Partition connection> As shown in FIG. 1, a plurality of partitions 10A shown in FIG. 1 can be arranged side by side along the horizontal direction (X direction). Similarly, a plurality of partitions 10B shown in FIG. 2 can also be arranged side by side along the horizontal direction (X direction). Further, as shown in FIG. 6, the partitions 10A and 10B can be arranged alternately along the horizontal direction (X direction).

[0078] As shown in FIG. 1, fasteners G are fixed to both end faces of the beam member 34 in the partition 10A (in other words, the outer side faces of the upper end portions of the column members 32). Therefore, when the partitions 10A are arranged side by side in the horizontal direction, these fasteners G are joined together to fix the partitions 10A to each other.

[0079] Similarly, fasteners G are also fixed to the end faces of the holding members 40B. Therefore, as shown in FIG. 6, in a state where the end portion of the beam member 34 is inserted into the holding member 40B, the fasteners G are arranged at positions corresponding to the end faces of the beam member 34. Thereby, when the partitions 10A and 10B are arranged side by side in the horizontal direction, these fasteners G are joined together to fix the partitions 10A and 10B to each other.

[0080] Also, although not shown, when a plurality of partitions 10B are arranged side by side in the horizontal direction, these fasteners G are joined together to fix the partitions 10B to each other.

[0081] When arranging and using the partitions 10A and 10B side by side, select the fasteners G to be applied so that the fasteners G facing each other are a combination of male fasteners and female fasteners.

[0082] When the partitions 10A and 10B are alternately arranged and used along the horizontal direction (X direction) in this way, compared with the case where only the partition 10A is used, the lightweight partition 10B is combined, so it is easier to carry.

[0083] In addition, by appropriately combining and using the partitions 10A and 10B, a highly flexible dust-proof structure can be formed according to the size and shape of the site.

[0084] <Modification example of sheet arrangement> The sheet 20A in FIG. 1 is arranged in a state of being bonded to the partition 10A using the fastener G, and the upper end is located at a position lower than the upper end of the beam member 34.

[0085] However, the embodiment of the present invention is not limited to this, and the sheet 20A may be formed so that, in a state of being bonded to the partition 10A, the upper end is located at a position higher than the upper end of the beam member 34.

[0086] In such a case, as shown in FIG. 7(A), it is preferable to fix the fastener G not only to the side surface of the beam member 34 facing the sheet 20A but also to the upper surface. Thereby, as shown in FIG. 7(B), the portion where the beam member 34 and the sheet 20A are fixed by the fastener G can be pressed against the ceiling. That is, the gap V at the portion where the beam members 34 of the two partitions are abutted against each other as shown in FIG. 10 described later can be blocked.

[0087] When the fastener G is fixed to the upper surface of the beam member 34, as shown in FIG. 7(C), the fastener G on the side surface of the beam member 34 may be omitted.

[0088] Similarly, the sheet 20B shown in FIG. 2 may also be formed so that, in a state of being bonded to the partition 10B, the upper end is located at a position higher than the upper end of the beam member 34.

[0089] Also, when a plurality of partitions 10A and 10B are connected and used, a wide sheet corresponding to the connected partitions can be used as the sheet 20C shown in FIG. 8.

[0090] Note that the upper end of the sheet 20C in FIG. 8 is disposed at a position higher than the upper end of the beam member 34. Further, a fastener G is fixed to the upper surface of the beam member 34. According to such an aspect, as shown in FIGS. 9(A) and (B), the portions of the beam member 34 and the sheet 20C fixed by the fastener G can be pressed against the ceiling. Note that FIGS. 9(A) and (B) show an example in which a plurality of partitions 10B are connected and used.

[0091] On the other hand, the upper end of the sheet 20D shown in FIGS. 10(A) and (B) is disposed at a position lower than the upper end of the beam member 34. In this case, the portions of the beam member 34 and the sheet 20C fixed by the fastener G cannot be pressed against the ceiling. Further, a gap V is likely to occur at a portion where the beam members 34 of the two partitions 10B are abutted against each other. Note that such an aspect of the sheet 20 is also included in the present invention.

[0092] <Operation and Effect> The partitions 10A and 10B according to the embodiment of the present invention are formed of air bodies 30A and 30B including column members 32 and beam members 34 of a film body and sheets 20A and 20B. The column members 32 and the beam members 34 are formed by filling air inside.

[0093] Therefore, it is lighter and easier to carry than a partition formed by attaching a sheet to a steel scaffold or the like. Further, by adjusting the air pressure, it can be stretched and held between the floor and the ceiling, so that the installation is easy.

[0094] Also, in the partition 10A of FIG. 1, both ends of the beam member 34 are connected to the upper end portions of the column members 32. Therefore, it is possible to reduce the weight as compared with a configuration of a portable partition in which the beam member protrudes laterally from the column members 32 arranged at the same interval as this aspect and is cantilevered.

[0095] On the other hand, in the partition 10B of FIG. 2, the column member 32 is formed as a single unit. Therefore, the weight can be reduced compared to the configuration of the portable partition provided with two column members. For this reason, the partitions 10A and 10B are easy to transport.

[0096] In addition, the partitions 10A and 10B are provided with a diaphragm 32P that divides the interior into a plurality of spaces. By thus dividing the interior of the column member 32 into a plurality of spaces, air can be filled into each space separately.

[0097] The speed at which air can be filled into any of the partitioned spaces is faster than the speed at which air is filled into the undivided column member at one time. For this reason, it is possible to first fill only the space in the lower part of the column member 32 with air.

[0098] Then, if the partitions 10A and 10B are transported to the installation position, the column member 32 is positioned, and then the upper part is filled with air, the partitions 10A and 10B can be smoothly set up.

[0099] In addition, as shown in FIG. 5(D), if the lower end portion of the column member 32 is bent and the bent state is held by the holding member 40A and air is filled, the overall height of the partitions 10A and 10B can be adjusted.

[0100] Furthermore, an air jack 60 is vertically stacked and attached to the lower end portion of the holding member 40A of the partitions 10A and 10B. That is, the air jack 60 can be vertically stacked and attached to the lower end portion of the column member 32.

[0101] For this reason, the height of the column member 32 can be adjusted. In addition, compared with the case where there is only one air jack 60, the adjustment cost of the height of the column member 32 is large. Thereby, the scattering of dust can be suppressed in buildings with various ceiling heights.

[0102] Also, if air is released from the air bodies 30A and 30B, the state in which the air bodies 30A and 30B are stretched between the floor and the ceiling is released, so they can be easily removed. And no restoration work or the like is required after removal. On the other hand, for example, in the case of a partition formed by attaching a sheet to the floor or ceiling using an adhesive tape or the like, work to remove the adhesive tape or the like may be required.

[0103] Also, the sheet 20A is joined to the air body 30A using the fastener G. For this reason, the sheet 20A is detachably joined across the longitudinal direction of the column member 32 and the beam member 34.

[0104] Similarly, the sheet 20B is joined to the air body 30B using the fastener G. For this reason, the sheet 20B is detachably joined across the longitudinal direction of the column member 32 and the beam member 34.

[0105] Thereby, after bending the lower end portion of the lower end portion of the column member 32 and attaching the holding member 40A, the sheets 20A and 20B can be joined to the air bodies 30A and 20B.

[0106] For this reason, compared with the case where the sheets 20A and 20B are not detachable, the length of the column member 32 is easy to adjust. Also, since the sheets 20A and 20B can be arranged along the floor surface or wall surface of the building, it is easy to ensure airtightness.

[0107] Also, in the partitions 10A and 10B, as shown in FIG. 8, fasteners G capable of joining, for example, the sheet 20C are fixed to the upper surface of the beam member 34. Thereby, as shown in FIGS. 9(A) and (B), the sheet 20C can be sandwiched and fixed between the beam member 34 and the ceiling surface, so the effect of suppressing the scattering of dust is great.

[0108] <Other Embodiments> In the partitions 10A and 10B of the above embodiment, a diaphragm 32P that divides the inside into a plurality of spaces is provided at the central portion in the longitudinal direction of the column member 32. However, the embodiment of the present invention is not limited to this. Even if the diaphragm 32P is not provided, it is lighter than the prior art and thus easy to transport.

[0109] Also, in the above embodiment, the holding member 40A includes the air jack 60. However, the embodiment of the present invention is not limited to this. For example, the air jack 60 may be omitted. Even if the air jack 60 is omitted, the length of the column member 32 can be adjusted by the holding member 40A.

[0110] Also, the air jack 60 may be directly fixed to, for example, the lower end portion of the column member 32. Even in such a mode, the length of the column member 32 can be adjusted by adjusting the amount of air filled in the air jack 60.

[0111] Also, in the above embodiment, the holding members 40A and 40B that hold the column member 32 and the beam member 34 are provided. However, the embodiment of the present invention is not limited to this. For example, the partitions 10A and 10B can also be configured not to include such holding members.

[0112] Even if the holding members are omitted from the partitions 10A and 10B, when the air bodies 30A or 30B are filled with air, the column member 32 is held in a state of being stretched between the floor and the ceiling. Since the air bodies 30A and 30B are formed of a flexible film body, even if the height from the floor to the ceiling of the building where the partition 10A or 10B is installed is greater than the height H4 of the column member 32, the column member 32 expands in the vertical direction and is held in a state of being stretched between the floor and the ceiling.

[0113] Also, a scale may be formed at the tip of the column member 32. The scale is a ruler indicating the ceiling height, engraved, for example, every 50 mm in the vertical direction on the outer peripheral surface of the column member 32.

[0114] This enables the appropriate insertion depth to be grasped when inserting the column member 32 into the holding member 40A after folding or tucking in the tip of the column member 32. If the insertion depth can be made appropriate, since the column member 32 and the holding member 40A are fixed by the fastener G, the height can be maintained. Thus, the present invention can be implemented in various modes.
