Description

  The present invention relates to a wall mounting member useful for easily mounting or mounting a sheet on an upper wall and / or a side wall, a sheet that can be easily mounted or mounted on the wall mounting member, and the wall mounting member. And a partition wall structure using a sheet (for example, a partition or smoke barrier structure or a smoke exhaust wall structure of a building).

  Various attachment members are used to partition a predetermined space with glass or a sheet or to shield a predetermined portion. In JP-A-7-555 (Patent Document 1), an aluminum rail having at least a sandwiching section for vertically sandwiching a smoke-proof wall and at least both outer and lower surfaces of the rail are attached. It is described that a smoke-proof hanging wall rail is formed with a stainless steel plate. The holding portion is formed in a U-shaped cross section in which the opening edge of the opening portion opened downward is bent inward and narrowed. However, in such a rail, a complicated process is required to mount the glass plate on the holding portion. Furthermore, since the ceiling wall is usually not formed accurately and smoothly and is inclined or waved in the vertical direction, when the rail is attached to the ceiling wall, the glass plate is also waved along with the wave of the ceiling wall. A partition wall cannot be formed by glass plates that are mounted and arranged in an orderly manner.

  Japanese Patent Laying-Open No. 2008-220507 (Patent Document 2) includes a rail arranged on a ceiling and a panel attached to the rail, and the rail is detachable from the rail body and the rail body. And a cover member having a U-shaped side wall that is open at the bottom and a supporting surface (supporting step portion) on both side walls facing each other, and the panel is attached to the frame A smoke-proof hanging wall is disclosed that includes a fiber reinforced sheet and an attachment member attached to the frame and having a locking portion that can be locked to a support surface of the rail. In JP 2008-220453 A (Patent Document 3), a suspension hook and a beat mounting groove are formed on a side surface of one inner wall of a rail having a U-shaped cross section that is open at the bottom, and a fiber reinforced sheet is provided. An attachment member having an engaging hook that can be engaged with the hanging hook of the rail is attached to one side of the attached rectangular frame. However, these structures are complicated, and it is necessary to attach the attachment member to the panel and attach the cover member by engaging the engaging portion with the support surface of the rail body, and the workability cannot be improved. Furthermore, it is necessary to attach a sheet | seat to a frame and to attach the attachment member which has a latching | locking part (or latching hook) to this frame, and a sheet | seat cannot be attached simply. Furthermore, when a rail is attached to the ceiling, distortion of the ceiling wall (inclination, wave out, etc.) affects the arrangement of the sheets, and the sheets cannot be attached in an orderly manner. In particular, even if the sheet is pulled from both sides, the sheet undulates and cannot be spread neatly.

  In JP 2008-220508 A (Patent Document 4), an upper edge region and a lower edge region of a fiber reinforced resin sheet are sandwiched and gripped over the entire length by a sheet mounting rail and a decorative rail, and the fiber reinforced resin sheet is held. A smoke-proof hanging wall that holds both ends of a resin sheet with a pair of end holders and applies tension to the fiber-reinforced resin sheet is disclosed. In this document, the seat mounting rail is composed of a rail body that is attached to the ceiling and a cover member that can be engaged with the rail body, and the upper edge region of the fiber reinforced resin sheet is formed by the grip surface of the rail body and the cover member. It is also described that the lower edge region of the sheet is gripped by the decorative rail body having a U-shaped cross section and the contact plate. However, the structure of the smoke-proof hanging wall is complicated, and the seat cannot be easily attached. Furthermore, in this example as well, when the mounting rail is attached to the ceiling wall, the seat can be attached in an orderly manner without causing downpipe or distortion due to the inclination of the ceiling wall or the wave (distortion). In order to correct the vertical flaw and the distorted portion, it is necessary to finely adjust the tension with a plurality of tension adjusting bolts.

  Japanese Patent Application Laid-Open No. 2007-82759 (Patent Document 5) discloses that a rail-shaped mounting frame provided on a ceiling portion of a building has a groove-shaped mounting frame main body opened downward, and both side surfaces constituting a groove of the main body. Each of the engaging portions formed at the lower portion of the housing includes attachment attachments that are respectively engaged. The attachment attachments are rotatably engaged with the engagement portions, and a plurality of teeth are formed on the outer periphery. There is also described a smoke barrier with a meshed portion and a projecting piece for attaching a pressing member. However, the structure of the mounting frame is also complicated, and the seat cannot be mounted with a simple operation. When the rail-like mounting frame is attached to the ceiling portion, similarly to the above, the distortion in the vertical direction or the surface direction of the ceiling wall is reflected as the vertical wall or distortion of the sheet, and the aesthetic appearance is impaired.

  In JP 2013-81747 A (Patent Document 6) and JP 2013-135931 A (Patent Document 7), the upper end of the seat is mounted in the dovetail mounting recess of the upper rail member that can be mounted on the ceiling. Alternatively, it is described that a retaining member (a core member or the like) for preventing the sheet from coming out of the dovetail mounting recess is mounted in the dovetail mounting recess in the accommodated state. In these partition wall structures, the sheet can be prevented from coming off with a relatively simple operation, but a step of attaching a retaining member to the dovetail-shaped mounting recess is required. In Patent Documents 6 and 7, a mounting frame body is attached to the ceiling wall, and the rail members are arranged on the mounting frame body so that the rail member is inclined or waved in the vertical direction or wobbled in the horizontal direction. Is preventing.

JP-A-7-555 (Claim 1, FIG. 1, FIG. 3) JP 2008-220507 A (claims, paragraphs [0010] [0011], FIGS. 2 and 3) JP 2008-220453 A (claims, paragraphs [0014] and [0015], FIG. 2) JP 2008-220508 A (Claims, paragraphs [0013] to [0017], FIGS. 2 and 3) JP 2007-82759 A (Claims, FIG. 1) JP 2013-81747 A (Claims, [0076], FIG. 1) JP 2013-135831 A (claims 2, 3 and 21, [0061], FIG. 1)

  In this example, a long wall attachment member (or rail member) 1 includes a plate-like attachment portion 2 that can be attached to a ceiling wall (not shown), and a first extension extending from an end portion of the plate-like attachment portion. An output restriction wall 3 and a second extension restriction wall 4 extending from the plate-like mounting portion 2 at a predetermined interval from the first extension restriction wall are provided. The distal ends of the pair of extension regulating walls 3 and 4 are bent inwardly to form hook-like locking portions 3a and 4a for the sheet slip-out regulating portion, and the pair of extension regulating walls 3 and 4 are formed. 4 is a slit-like shape with a narrowed tip, and an elongated retaining recess 5 is formed. Further, a connecting member 7 is provided on the lower wall of the plate-like mounting portion 2 between the pair of extension regulating walls 3 and 4 so that the wall mounting member (or rail member) 1 can be adjacently connected while being positioned. A connecting groove 6 that can be mounted is formed.

  On the other hand, the sheet 10 is formed of a glass fiber reinforced synthetic resin sheet from the viewpoint of flame retardancy, heat resistance, and strength, and the upper end portion of the sheet body 11 is bent (or folded), and from the bent leading end portion (upper end edge). Folding portions are integrated at a predetermined interval, and a flap-shaped locking piece 12 that can be engaged with the hook-shaped locking portions 3a, 4a is provided. The flap-shaped locking piece 12 is solidified by inclining in the oblique direction (in this example, obliquely downward in this example) from the sheet main body 11 corresponding to the locking portions 3a and 4a, and the leading end is released from the sheet main body 11. The sheet body 11 can be expanded and contracted or deformed in the thickness direction. Such a sheet 10 is overlapped by folding the upper end portion of the sheet main body 11 with a predetermined width, and is stacked at a predetermined interval (leaving a predetermined width) from the folded front end portion (edge) of the sheet main body 11. It can be formed by integrating the mating part (integrated by an integration means such as welding), and an elongated ring-shaped part 13 that can be expanded or contracted in the thickness direction of the sheet body 11 can be formed at the upper end of the sheet 10. The flap-shaped locking piece 12 can be formed adjacent to the ring-shaped portion 13. Further, the flap-like locking piece 12 is freely moved (moved) in the extending direction of at least the pair of extension regulating walls 3 and 4 in the retaining recess 5 in the accommodated state in the retaining recess 5. Is possible.

  The flap-shaped locking piece 12 is solidified or cured by inserting a wedge-shaped spacer from the bent tip (free edge) at the overlapping portion of the sheet body 11 and welding the overlapping portion. Can be formed. For example, as shown in FIG. 5, the overlapping portion of the sheet body 11 is bent, leaving a predetermined width from the leading end, and linear (continuous or spaced at predetermined intervals) in the longitudinal direction (for example, in the lateral direction). ), A wedge-shaped spacer 14a is inserted from the bent tip, and an overlapping portion (for example, an insertion depth portion (tip portion) of the spacer and an overlapping portion corresponding to the bent tip portion) is welded through the spacer. By doing so, the flap-shaped locking piece 12 can be formed. The angle of the locking piece 12 with respect to the sheet body 11 can be adjusted or set by adjusting the angle of the tip of the spacer 14a and welding the overlapped portion.

  In such a wall attachment member (or rail member) 1, as described above, after attaching the plate-like attachment portion 2 to the ceiling wall using the screw member 14, the upper edge portion of the sheet 10 is attached to the wall attachment member. A partition wall can be easily formed by inserting or mounting along the slit-shaped retaining recess 5 from below 1. In particular, when the side edge portion (upper end portion) of the sheet 10 is inserted into the retaining recess 5 through the slit-shaped opening at the tip of the pair of extension regulating walls 3 and 4, the elongated ring-shaped portion 13 and the flap-shaped portion Since the locking piece 12 can be expanded and contracted or deformed in the thickness direction, the sheet 10 can be smoothly inserted into the retaining recess 5. And since the sheet | seat 10 is reinforced with the glass fiber, it can insert smoothly along a slit-shaped opening part even from the downward direction. Then, when the flap-shaped locking piece 12 of the sheet 10 enters the retaining recess 5 deeper than the hook-shaped locking portions 3a, 4a, the flap-shaped locking piece 12 compressed in the thickness direction is formed. Since the sheet 10 is opened and spreads, the flap-shaped locking piece 12 is firmly engaged with the hook-shaped locking portions 3a and 4a by pulling the sheet 10 downward, thereby preventing the sheet 10 from coming off.

  Further, in the formation of the partition wall, the partition wall forming member is formed by using the wall mounting member 1 and a pair of sheet mounting members 15 and 16 to which both side walls of the partition wall and both side portions of the sheet 10 can be respectively mounted. The sheet 10 can be attached while being tensioned in the lateral direction by the pair of sheet attachment members 15 and 16. As such sheet attachment members 15 and 16, for example, plate-shaped sheet sandwiching portions 15 a and 16 a having an L-shaped cross section and capable of sandwiching the sheet main body 11, and sections orthogonal to the sheet sandwiching portion. An L-shaped sheet mounting member (L-shaped angle) having plate-shaped wall mounting portions 15b and 16b that can be mounted on the side wall of the wall can be used. Specifically, after the upper edge portion of the sheet 10 is inserted or attached to the retaining recess 5, both sides of one side portion of the sheet body 11 are connected to the first pair of adhesive layers via the adhesive layers 10 a and 10 b. The L-shaped sheet attachment members 15 and 16 can be integrated by being clamped by the sheet clamping portions 15a and 16a and fastened by a screw member 19a such as a screw and a nut 19b. Then, the wall attachment portions 15b and 16b of the first pair of L-shaped sheet attachment members 15 and 16 are attached to the side walls of the partition wall with a screw member 20 or the like. Thereafter, similarly to the above, the sheet sandwiching portions 17a and 18a of the second pair of L-shaped sheet attachment members 17 and 18 are attached to both surfaces of the other side portion of the sheet body 11 via the adhesive layers 10a and 10b. Between the screw member 19a and the nut 19b. Then, the seat body 11 is tensioned, and the wall attachment portions 17b and 18b of the second pair of L-shaped sheet attachment members 17 and 18 are attached to the opposing side wall portions with the screw members 20 or the like, thereby tensioning the seat 10. Can be spread evenly. In particular, in the retaining recess 5, a locking piece (slip restricting portion) 12 is accommodated in a form that can freely move with play (or can move in the vertical direction). In other words, the slip-off restricting portion (thickness restricting portion) 12 of the sheet 10 is freely movable in the up-down direction (extending direction of the pair of extension restricting walls 3, 4) and in the front-rear direction within the retaining recess 5. It is. Therefore, even if the wall surface of the ceiling wall is distorted (tilt, wave, etc.), the distortion of the wall surface of the ceiling wall is caused by the play of the locking piece (removal restricting portion) 12 in the elongated retaining recess 5. The sheet 10 can be stretched with uniform tension. Further, the sheet 10 is attached to both side portions with a pair of first and second sheet sandwiching portions 15a to 18a with a double-sided adhesive tape, and the first wall mounting portions 15b and 16b are attached to one wall surface, and then the sheet By attaching the second wall attaching portions 17b and 18b to the other side wall while pulling 10, the seat 10 can be attached smoothly and efficiently. At that time, the sheet member 10 can be tensioned and stretched by screwing the screw member 20 into the side wall of the partition wall and moving it forward.

  The side portion of the sheet body 11 may be sandwiched between the sheet sandwiching portions 15a and 16a (17a and 18a) of the pair of L-shaped sheet attachment members 15 and 16 (17 and 18), and an adhesive layer is necessarily required. is not. The flap-shaped locking piece 12 welds the overlapping portion (folded portion) of the upper end portion (and / or the side end portion) of the sheet body 11 in the longitudinal direction in the form of a line or spot (particularly linear). In this case, the width of the welded portion in the longitudinal direction may be increased (continuously or at intervals), and the locking piece 12 may be inclined in a flap shape. Further, without forming the folding ring-shaped portion 13, the end portion of the narrow flap piece (or narrow strip-shaped flap) is integrated with the side edge portion (upper end portion) of the seat body 11. May be. Furthermore, the folded portion can be welded at intervals in the longitudinal direction, and the folded portion of the non-welded portion can be lifted from the sheet main body to be a locking portion.

  The angle of the flap-shaped locking piece 12 with respect to the seat body 11 may be any angle as long as it can be locked with respect to the locking portion of the wall mounting member, and is, for example, 10 to 60 °, preferably 20 to 50 °, and more preferably. It may be about 30 to 45 °. In many cases, the flap-shaped locking piece 12 is solidified at a predetermined angle with respect to the sheet main body 11 and maintains a predetermined extended form from the sheet main body 11.

  In the above example, in the first and second pair of L-shaped sheet attachment members 15 to 18, the upper portions of the wall attachment portions 15 b to 18 b extend compared to the sheet sandwiching portions 15 a to 18 a. Steps (or notches) corresponding to the cross-sectional shape of the wall mounting member 1 are formed on the upper end walls of the wall mounting portions 15b to 18b, and both side portions (both ends in the longitudinal direction) of the wall mounting member 1 are formed. ). In addition, in the state which attached or attached the edge part of the wall attachment member 1 to a pair of L-shaped sheet attachment members 15-18, it is 1st to the step part (notch part) formed in the said wall attachment parts 15b-18b. And the second extension regulating walls 3 and 4 may be accommodated, and the leading ends of the hook-shaped locking portions 3a and 4a are the upper end walls or upper end surfaces of the sheet clamping portions 15a and 16a. And may be in contact with or abutting.

Wall mounting member (or rail member)
The wall attachment member (or rail member) includes a plate-like attachment portion that can be directly or indirectly attached to the upper wall and / or the side wall, and the plate-like attachment portion is attached to the wall surface. Although it may be attached directly or indirectly (for example, via an interposed member such as a housing member that can accommodate the plate-like attachment portion), it can absorb distortion of the wall surface, and is preferably directly on the wall surface. It is attached. Further, the plate-like attachment portion may be attached to either the upper wall or the side wall. For example, the plate-like attachment portion is attached along the side wall, and the sheet is spread in the lateral direction on the standing wall attachment member. May be. In a preferred embodiment, a plate-like attachment portion may be attached to the upper wall (particularly the ceiling wall), and the seat may be attached while being stretched down from a wall attachment member extending in the lateral direction.

  The wall mounting member (or rail member) has a slit-shaped retaining recess to which a seat can be attached in order to partition a space such as a room (such as an upper space). In order to form the retaining recess, a pair of extension regulating walls extend from the plate-like mounting portion at a predetermined interval in such a manner that the tip end portion is bent or curved and narrowed. The pair of extension regulating walls are formed so as to extend in the axial direction of the plate-like mounting portion (usually over the entire length of the plate-like mounting portion). The retaining recess formed by the pair of extension regulating walls has a shape in which the tip is narrowed and opened along the longitudinal direction (such as a dovetail shape having a narrow width), and allows insertion of the sheet. And the removal of the sheet from the removal restricting portion is restricted. In other words, in the retainer recess (prevention space), the end of the sheet is slidable or movable in the lateral direction (particularly slidable or movable in the lateral direction), and the detachment in the longitudinal direction is restricted. What is necessary is just to be able to mount | wear or accommodate in (prevention state). In such a form, the partition wall can be formed in a retaining state simply by inserting or mounting the sheet into the retaining recess. The pair of extension restricting walls (retaining recesses) may be asymmetric in cross-sectional shape, but the cross-sectional shape is symmetrical in order to improve the engagement with the sheet slip-out restricting portion. It is advantageous.

  The tip ends of the pair of extension regulating walls need only be narrowed, but in order to reliably prevent the sheet slip-out restricting portion from slipping out, the tip portion usually forms a locking portion for the sheet slip-out restricting portion. ing.

  The pair of extension regulating walls and retaining recesses may have various forms. For example, in the wall mounting member 21 shown in FIG. 6A, a plate-shaped mounting portion 22 that can be mounted on a ceiling wall or the like. And a pair of extension restricting walls 23, 24 extending from the plate-like attachment portion after a predetermined interval, and a curved locking portion 23a in which the tip ends of the pair of extension restricting walls are curved inward and narrowed. , 24a. In the wall mounting member 31 shown in FIG. 6 (B), the tip portions of the pair of extension regulating walls 33 and 34 extending from the plate-like mounting portion 32 are curved inward as in FIG. 6 (A). Narrow curved locking portions 33a, 34a are formed, and the intermediate portions of the pair of extension regulating walls 33, 34 are connected by a bridge portion 35 in order to increase the strength of the pair of extension regulating walls 33, 34. Has been.

  Further, the wall mounting member 41 shown in FIG. 6C includes a plate-shaped mounting portion 42 and a pair of extension regulating walls 43 and 44 extending from the plate-shaped mounting portion at a predetermined interval. One extension regulating wall 44 of the pair of extension regulating walls 43, 44 is directed from the middle part toward the other extension regulating wall (in this example, the extension regulating wall on the end side) 43. It has a form in which the tip portion is curved and narrowed, and the portion that is curved and narrowed can function as the locking portion 44a.

  In the wall mounting member having such a curved locking portion, as will be described later, the wall locking member such as a thickness omission restricting portion formed on the upper edge portion and / or the side edge portion of the sheet with respect to the curved locking portion. A stop part (disengagement restricting part) can be locked.

  As described above, the plate-like attachment portion and the pair of extension restriction walls may be integrated to form a wall attachment member, and the first attachment member and the first extension restriction wall have a first attachment restriction wall. You may comprise with an attachment member and the 2nd attachment member which can be mounted | worn or positioned with respect to this 1st attachment member, and has the other extension control wall.

  A wall mounting member 51 shown in FIG. 6D has a cross section L including a plate-shaped mounting portion 53 that can be mounted on a ceiling wall, and a first extension regulating wall 54 that extends from the end of the plate-shaped mounting portion. A first mounting member 52 having a letter shape; a plate-shaped mounting wall 56 that can be mounted in a mounting groove of the first mounting member 52; and a second extension regulating wall 57 that extends from the end of the mounting wall. And a second mounting member 55 having an L-shaped cross section. A shallow groove-shaped mounting groove 53a is formed in the lower wall of the plate-shaped mounting portion 53 of the first mounting member 52, and the plate-shaped mounting wall 56 of the second mounting member 55 can be mounted in this mounting groove. It is. The plate-like mounting wall 56 has projections (projections) 56a and 56b protruding at both sides in the width direction of the plate-like mounting wall 56 in accordance with the attachment to the ceiling wall by screw members. In order to increase the pressure-bonding strength against the plate-like mounting portion 53, it is formed in a U-shaped cross section. Further, in order to reliably position (or mount) the plate-shaped mounting wall 56, the tip of the plate-shaped mounting portion 53 can be bent toward the plate-shaped mounting wall 56 to guide the protruding portion 56a of the plate-shaped mounting wall 56. A bent portion 53b is formed. Therefore, the plate-like mounting wall 56 of the second mounting member 55 is mounted in the mounting groove 53a of the first mounting member 52, and is mounted on the ceiling wall using a screw member, whereby the first mounting member 52 and the second mounting wall And a pair of extension regulating walls 54 and 57 extending in a direction orthogonal to the plate-like mounting portion 53 at a predetermined interval from the plate-like mounting portion 53. it can.

  The distal end portions of the first extension regulating wall 54 and the second extension regulating wall 57 are bent in a hook shape in the shape of a V-shaped cross section on the inside, and are bent or hook-like locked to the sheet slip-out restricting portion. 54a and 57a are formed, and the pair of extension regulating walls 54 and 57 form a slit-like recess 58 having a narrow tip end portion and an elongated retaining recess 58.

  The wall mounting member 61 shown in FIG. 6 (E) is similar to FIGS. 1 and 2 in that the first mounting member 62 having an L-shaped cross section and an L-shaped cross section that can be positioned with respect to the first mounting member. The first mounting member 62 includes a shallow groove mounting groove 63a formed on the lower wall and a bent portion 63b formed on one end. A plate-like attachment portion 63 provided and a first extension regulating wall 64 extending from the other end of the plate-like attachment portion are provided. On the other hand, the second mounting member 65 includes a plate-shaped mounting wall 66 that can be mounted or positioned in the mounting groove 63a, and a second extension regulating wall 67 that extends from the end of the plate-shaped mounting wall. I have. The first extension restriction wall 64 and the second extension restriction wall 67 have tip portions curved inward in a U-shaped cross section to form locking portions 64a and 67a.

  As described above, various forms can be adopted as the wall mounting member including the extension restricting wall. For example, it is only necessary that the distal end portions of the pair of extension restricting walls are narrowed to restrict or prevent the sheet from being removed. The pair of extension regulating walls may be curved in a direction approaching each other at the tip portion. The tip of the extension regulating wall (at least one of the extension regulating walls, preferably both of the extension regulating walls) is preferably bent or curved in a U-shaped or V-shaped cross section inside, In particular, it is preferable to form a hook-shaped locking portion. In the above example, one of the pair of extension regulating walls extends downward from the end of the plate-like mounting portion, but the pair of extension regulating walls leaves both sides. The plate-shaped mounting portion may extend from the central portion at a predetermined interval.

  The long wall mounting member (or rail member) can be formed, for example, by extrusion molding of aluminum. By such extrusion molding, a pair of extension regulating walls may be formed in a form in which the tip portion is expanded. In such a case, the extension method (or posture) of the pair of extension regulating walls may be corrected after the extrusion molding.

  In order to facilitate the insertion or mounting of the sheet, in a long wall mounting member (rail member), a slit-like opening (a narrow opening of a retaining recess) is formed along the longitudinal direction by a pair of extension restricting parts. ), And the upper edge and / or side edge of the sheet can be mounted in the retaining recess (retaining space). In particular, the slip-out restricting portion formed on the upper edge portion and / or the side edge portion of the sheet is locked with at least the front end portions (particularly the lock portions) of the pair of extension restricting portions, and the sheet is prevented from slipping out. It can be installed.

  Most of the wall surfaces (the wall surfaces of the upper wall and / or the side wall) are not completely flat, and there are usually distorted portions such as slopes, waves, and uneven portions on the wall surfaces. In the present invention, even if the wall mounting member is long and there is a distorted portion on the wall surface (the wall surface of the upper wall and / or the side wall), the sheet slip-out restricting portion is inserted into the retaining recess, or Since it is attached, the distortion can be removed and absorbed by the play of the restricting portion, and the compartment can be formed without causing wrinkles or distortion in the sheet. In order to absorb the distortion of the wall surface, it is not possible to absorb the distortion of the wall surface when the removal restricting portion is closely attached to the retaining recess. Therefore, it is preferable that the slip-out restricting portion can move freely in the slip-off preventing recessed portion, and in particular, it can freely move in at least the extending direction of the pair of extension restricting walls. The retaining recess that allows the slip-out restricting portion to move may form a space having a circular cross section or an ellipse, or a space having a square cross section. In order to form a large idle space in at least the extending direction of the pair of extension regulating walls, a preferable retaining recess (a retaining space) forms an elongated space. The length of the retaining recess (the retaining space) is a length that allows the retaining portion to move freely, for example, the length from the end (such as the upper end) of the sheet to the retaining portion (for example, from the end of the sheet to the flap) 1.2 times or more (for example, about 1.3 to 15 times), preferably 1.5 times or more (for example, about 1.5 to 10 times), It may be preferably 1.7 times or more (for example, about 2 to 5 times), or 1.3 to 5 times (for example, 1.5 to 3 times).

  In addition, when attaching a some elongate wall attachment member to a wall surface (for example, ceiling wall surface), the axial direction of a wall attachment member may shift | deviate in an adjacent part. In such a case, a connecting groove such as a key groove is formed in the plate-shaped mounting portion in the longitudinal direction, and a connecting member (a connecting member such as a rod-shaped body or a plate-shaped body) is formed in the connecting groove of the adjacent wall mounting member. By inserting or mounting, it is possible to prevent the displacement of adjacent wall mounting members. In addition, a connection ditch | groove can be formed in the suitable place of a wall attachment member, and as shown in the said FIG. 1, the lower wall of a plate-shaped attachment part may be sufficient, and an upper wall may be sufficient as it.

  When a wall mounting member (rail member) is mounted on a wall surface (ceiling wall, etc.) by a fixing means such as a screw member, a groove, a recess or a hole serving as an index of a fixing position is provided on a plate-shaped mounting portion of the wall mounting member (rail member). May be formed. For example, if a groove is formed along the longitudinal direction on the lower wall surface of the plate-like mounting portion, or a recess or a hole is formed at intervals in the longitudinal direction, these grooves and recesses are indicated as an indication of the fixing position by the fixing means. It is possible to improve the workability and positioning accuracy.

  The long wall mounting member may have a planar shape extending linearly or curved while maintaining a retaining recess (a retaining space) by the pair of extension regulating walls.

The sheet sheet is generally required to have at least an end portion (upper end portion and / or side portion) that can be mounted or accommodated in the retaining recess, and may be formed of fabric, plastic, or the like, impregnation treatment, fiber reinforcement, etc. It may be strengthened by. The sheet (for example, a sheet used as a smoke barrier or smoke exhaust wall) is a flame-retardant or non-flammable sheet, for example, a fiber-reinforced synthetic resin sheet such as a non-flammable synthetic resin sheet or a glass fiber reinforced synthetic resin sheet (Glass fiber base fabric containing sheet etc.) etc. may be sufficient. As the sheet, a sheet that can be folded or folded at the end (such as a non-combustible or flame-retardant sheet), a flexible sheet (such as a non-combustible or flame-retardant sheet), and particularly flexible and weldable. An incombustible sheet (such as an incombustible or incombustible sheet) is used. The sheet may be opaque, but is usually often transparent or translucent. The sheet may be colored as necessary. The sheet may be weldable in order to easily form the locked portion. The sheet may have flexibility, but may be a high-strength sheet in order to facilitate insertion or mounting operation into the retaining recess.

  At the end of the sheet, a slip-out restricting portion is formed to restrict detachment from the slip-out preventing recess, and the slip-out restricting portion is formed by bending or folding the end portion of the sheet, The diameter is often increased by joining thick-walled members.

  As the sheet drop-out restricting portion, various forms of restricting portions can be formed according to at least the shape of the pair of extension restricting portions (particularly the shape of the locking portion). The sheet slip-out restricting portion has a locking piece (for example, a locking piece whose lower end portion extends in the lateral direction and is inclined) that can be locked with the locking portion at the distal end portion of the pair of extension restriction walls. For example, as shown in FIG. 7 (A), a belt-like body (narrow width) having a locked portion 71a having an arrow-shaped cross-section or an inverted V-shape at the top at the edge of the sheet main body 11, as shown in FIG. 7 (B), a belt-like body (locked band) having a locked portion 72a having an arrow-like cross section or an anchor shape at the top, as shown in FIG. 7C. As shown in FIG. 7C, the top portion has a locked portion 73a having a cross-sectional jellyfish shape (a U-shaped cross section centering on the mounting portion with respect to the seat body). It is formed by attaching a band (locked band) 73 to the edge of the sheet body 11 Good.

  Moreover, the form of the to-be-engaged part (sheet | seat removal | restriction control part) for preventing the removal from the front-end | tip part of a pair of said extension restriction | limiting wall is thick-walled parts, such as a cross-sectional polygonal shape, a cross-sectional circle shape, or an elliptical shape ( 7 (D), for example, as shown in FIG. 7 (D). A locking section 74a having a quadrangular cross section formed on the top of the band (stop band) 74, and a circular or elliptical cross section formed on the top of the band (locked band) 75 as shown in FIG. The form of the to-be-latched part 75a may be sufficient. Further, as shown in FIG. 7 (F), a band-like body (narrow-width locked band) 76 that forms a sheet slip-out restricting portion includes a locked portion 76a having a circular cross section and the locked portion. And a pair of thin strips (thin leg portions) 77a and 77b that can sandwich the edge of the sheet body 11 from both sides.

  The sheet slip-out restricting portion (locked portion) may be accommodated in the retaining recess between the extension restricting walls and may be locked or engaged with the hook-shaped locking portion. For the retaining recess, it may be inserted in the depth direction of the retaining recess from the opening of the hook-shaped retaining portion, and the retaining restriction portion (locked) in the form of FIGS. Part), the thickness of the removal restricting part may be made larger than the opening part of the retaining recess, and the sliding part may be inserted in a sliding manner from the side opening of the retaining recess.

  Further, without using the belt-like portion, for example, as shown in FIG. 7G, a narrow body 78a having a predetermined thickness larger than the opening of the retaining recess is welded to the sheet body 11 (melt-compression bonding). For example, the locked portion 78 may be formed by integration. Further, the narrow body may be welded to the sheet body throughout, or may be welded in the longitudinal direction in a form in which a groove-like recess (pressing or compressing portion) is formed at the center in the width direction of the narrow body. Good.

  Further, as shown in FIG. 7H, the sheet slip-out restricting portion 79 folds the upper end portion of the sheet body 11 to form a first fold portion (or folded portion) 79a, and further, the first fold portion 79a. Part is folded to form a second folded part (or folded part) 79b, and the overlapped part of the first folded part 79a and the second folded part 79b is integrated with the sheet body 11 by welding or the like. The locking part 80 may be formed. The pull-out restricting portion having such a folded structure or multiple overlapping structure can reinforce the locked portion 80 regardless of the material of the seat body, and can surely prevent the pair of extension restricting walls from coming off from the front end portions. . In addition, as long as the removal restricting portion can be inserted, the number of times of folding is not particularly limited. For example, as shown in FIG. 1, it may be 1 or 2 to 5 times (for example, 2 to 3 times). It may be a degree.

  The belt-like body is attached to the sheet main body 11 by using various integration means such as welding, bonding, stitching (including stitch-like stitching), and a binding tool such as a stapler (stapler). They may be attached and integrated with a binding member such as a staple.

  The folding and folding portions of the sheet end portion may be integrated with each other preferably by a welding means such as a welder, a sewing means, a binding member or the like. In many cases, a slip-out restricting portion is formed in advance on the end portion of the sheet by a welding process. Further, the end portion of the sheet may be reinforced by resin impregnation, a reinforcing material, or the like. In addition, the edge part of a sheet | seat may be processed beforehand and a predetermined process may be given at a construction site.

  The upper edge and / or side edge of the sheet is inserted or mounted along the slit-shaped retaining recess from the side of the wall mounting member as described above, depending on the form of the sheet slip-out restricting portion. Alternatively, it may be inserted into or attached to the retaining recess from below and / or from the side through the slit-shaped opening.

  The method for manufacturing the sheet is not particularly limited as long as it can be mounted or attached to the wall mounting member. As described above, the upper edge and / or side of the sheet main body is integrated by an integration unit (welding unit using a welder). A slip-out restricting portion (a slip-out restricting portion that can be locked in the slip-off preventing recess of the wall mounting member and can be accommodated with play in the slip-off preventing recess) may be formed at the edge.

  Furthermore, the wall attachment member may include a shielding member for shielding an attachment portion with respect to the wall surface. As shown in FIGS. 1 and 2, the long wall mounting member 101 shown in FIG. 8 has a plate-shaped mounting portion 102 and a predetermined interval from the plate-shaped mounting portion 102 on one side of the plate-shaped mounting portion. First and second extension regulating walls 103 and 104 extending downward, and a bent extension portion 106 extending downward from the other end of the plate-like attachment portion 102 are provided. The distal end portions of the first extension regulating wall 103 and the second extension regulating wall 104 form locking portions 103a and 104a that are bent in a cross-sectional shape on the inside, and the first extension regulating wall 103 and the second extension regulating wall 103 The two extension regulating walls 104 form an elongated retaining recess 105 having a narrow slit-like opening and a narrowed tip.

  Also in this example, the sheet 10 is formed in the same manner as the sheet shown in FIGS. 1, 2, and 5, and the upper end of the sheet 10 is entered from below through the slit-shaped opening, so that the inside of the retaining recess 105. Can be inserted smoothly. Moreover, the flap-shaped locking pieces 12 that are opened and spread firmly engage with the hook-shaped locking portions 103a and 104a to prevent the sheet 10 from coming off.

  In this example, after the wall attachment member 101 is attached to the ceiling wall 15a with the screw member 14, the screw member 14 is shielded, so that the inner wall (between the second extension regulating wall 104 and the bent extension portion 106) ( A mounting groove in which the cover member 107 can be mounted is formed in the facing wall. By using such a cover member 107, the screw member 14 can be shielded and the appearance can be improved. The cover member (or shielding member) may be detachable.

  Furthermore, the sheet mounting member for forming the partition wall structure in combination with the wall mounting member is not limited to the sandwich structure, and may be any type that can hold the end portions (for example, both side portions) of the sheet in various forms. The end portion (for example, the side portion) of the sheet main body and the sheet attachment member may be firmly integrated without using an adhesive. For example, the wall mounting member, a pair of sheet clamping portions capable of clamping an end portion (for example, a side portion) of the sheet, and a wall extending in an L shape from the sheet clamping portion and attachable to the side wall A partition wall forming member may be constituted by a pair of sheet attaching members provided with an attaching portion, and an end portion (for example, both side portions) of the sheet may be held or sandwiched, and the sheet may be stretched. FIG. 9 is a schematic exploded perspective view showing another partition wall structure of the present invention, and FIG. 10 is a schematic plan view of the first pair of seat mounting members shown in FIG.

  In this example, the first pair of sheet attachment members 115 and 116 capable of sandwiching one side portion of the sheet main body with the side portion of the sheet main body are formed in an L-shaped cross section in the same manner as described above. Plate-shaped sheet clamping portions 115a and 116a, and plate-shaped wall mounting portions 115b and 116b that can be mounted on the side walls of the partition wall, forming an L-shaped angle. Of the opposing surfaces of the sheet clamping portions 115a and 116a, on the front end side (front side), a V-shaped groove 117 that can be meshed or fitted with each other is adjacent and extends in the longitudinal direction. A fastening region (fastening part) for fastening a pair of sheet clamping parts 115a and 116a facing each other by sandwiching the side part of the sheet main body 11 on the plate-like wall mounting part side. 119 is formed, and in this fastening region, the pair of sheet clamping portions 115a and 116a can be fastened using the screw member 19a and the nut 19b. That is, the clamping area (clamping part) 118 and the fastening area (fastening part) 119 are separated.

  Therefore, after inserting or mounting the engaged portion (thickness regulating portion) 78 on the upper edge of the sheet 10 from the lateral direction with respect to the retaining recess 5 of the wall mounting member 1, Is sandwiched between the sheet sandwiching portions 115a and 116a of the first sheet mounting members 115 and 116, the side portions of the sheet main body 11 are firmly sandwiched by the V-shaped grooves 117 in the sandwiching region (clamping portion) 118. Thus, in the fastening area 119, even if the pair of sheet clamping portions 115a and 116a are fastened by screwing of the screw member 19a, the twisting force by the screw member 19a may act on the sheet body 11. The sheet 10 can be spread evenly. Even if the end portion of the sheet 10 is located in the fastening region 119 and the twisting force by the screw member 19a acts on the end portion of the sheet 10, the side portion of the sheet body 11 is firmly sandwiched in the sandwiching region 118. Therefore, the sheet 10 can be extended without forming wrinkles or waves.

  The wall attaching portions 115b and 116b can be attached to the side walls with the screw members 20 in the same manner as described above. The first pair of seat mounting members 115 and 116 indicate the screwing positions of the screw members 19a and 20 (indicators or marks), and are screwed or screwed in while preventing displacement. A recess, a depression, or a pore is formed at a predetermined interval. Note that the screwing position may be a shallow groove-like or streak-like recess formed along the longitudinal direction.

  Further, the first pair of sheet mounting members 115 and 116 are prevented from being displaced by the butting operation, so that the facing portions of the wall mounting portions 115b and 116b can be fitted with positioning portions (positioning uneven portions, meshing portions) that can be fitted to each other. Part) 120 is formed. In this example, the positioning portion 120 is formed by a convex ridge portion having a trapezoidal cross section and a cross-sectional concave groove portion adapted to the convex ridge portion. Therefore, even if the side part of the sheet body 11 is clamped by the clamping region (clamping part) 118 having the V-shaped groove 117, the pair of sheet attachment members 115 and 116 are not displaced and the pair of sheets The sandwiching portions 115a and 116a can be sandwiched, and the wall attachment portions 115b and 116b can be attached to the side walls.

  9 and 10 illustrate an example in which one side portion of the sheet main body is sandwiched, but both side portions of the sheet main body may be sandwiched. That is, by using a second pair of L-shaped sheet attachment members (not shown) having the same structure as that of the first pair of sheet attachment members 115 and 116, the other side portion of the sheet body 11 is attached. While being able to be firmly clamped by the V-shaped groove of the second pair of sheet clamping portions, the second pair of wall mounting portions can be mounted to the other side wall.

  Further, in the same manner as described above, in the pair of L-shaped sheet attachment members 115 and 116, the wall attachment portions 115b and 116b extend beyond the sheet clamping portions 115a and 116a, and the upper ends of the wall attachment portions 115b and 116b. Corresponding to the cross-sectional shape of the wall mounting member 1, a stepped portion (or notch) that can accommodate the first and second extension regulating walls 3, 4 is formed on the part wall. The receiving part for receiving the both sides of is formed.

  Furthermore, in this example, the width (from the pair of extension regulating walls 3, 4 of the lower wall of the plate-like mounting portion 2, not the lower wall of the plate-like mounting portion 2 between the pair of extension regulating walls 3, 4 ( Alternatively, a plate-like connecting member (elongated plate) 27 that can be attached to a ceiling wall (not shown) by a screw member or the like can be disposed on the lower wall of the extending portion extending in the direction of the side portion. Yes, with this connecting member, the adjacent portion of the wall mounting member (or rail member) 1 can be connected while positioning the wall mounting member (or rail member) 1. The connecting member 27 is formed with a marker portion (notch portion in this example) 27a on a predetermined side portion in the longitudinal direction, and a marker of an entry or insertion length with respect to the lower wall of the plate-like attachment portion 2 It is said.

  Note that the sheet clamping portion does not need to have a clamping area, it is sufficient if it has at least a fastening area, and the fastening area may be formed in at least a part of the opposing part of the sheet clamping part, You may form over. In a preferred embodiment, the sheet clamping unit includes at least a clamping area and a fastening area. The sheet clamping portion only needs to include at least one clamping portion and at least one fastening portion, and may be formed adjacent to each other sequentially from the leading end side of the sheet clamping portion toward the wall mounting portion. Alternatively, the sandwiching portion, the fastening portion, and the sandwiching portion may be formed sequentially. Further, in the sheet clamping portion, it is not always necessary to separate the clamping area and the fastening area. However, as described above, when the clamping area and the fastening area are separated, it is effective to generate wrinkles or the like on the sheet. The sheet can be extended while preventing it.

  The sandwiching area 118 is not limited to a groove having a V-shaped cross section, but is formed by a groove that can be abutted with each other (such as a cross-sectional uneven fitting or meshing), for example, a groove having a U-shaped cross section or a trapezoidal cross section. Also good. For example, in a state where the sheet is sandwiched, the pair of sheet sandwiching portions may form a sandwiching portion that is continuous in a cross-sectional mountain shape, saw-tooth shape, wave shape, or S-shape.

  The positioning portion 120 formed at the facing portion of the wall mounting portions 115b and 116b is not necessarily required, but in order to perform the sheet mounting operation smoothly, the positioning portion is formed at the facing portion of the wall mounting portions 115b and 116b. Is advantageous. The positioning portion is not limited to the above-described form, and is formed by a convex shape (such as a triangular or quadrangular ridge) and a concave groove (such as a V-shaped or U-shaped groove) formed along the longitudinal direction. You may form, and you may comprise by the protrusion part and recessed part which were formed in the longitudinal direction at intervals. Further, as long as there is no hindrance to the attachment of the seat, the positioning portion may be formed at an appropriate position of the facing portion of the wall attachment portions 115b and 116b, or may be formed in the fastening area. That is, the positioning portion may be formed in the fastening area of the pair of sheet clamping portions and / or the opposing portion of the pair of wall mounting portions.

  Furthermore, a tension adjusting unit may be used to tension the seat body 11 and attach it to the wall surface. 11 is a schematic exploded perspective view showing an example of the tension adjustment unit, and FIG. 12 is a schematic cross-sectional view of the tension adjustment unit shown in FIG.

  The tension adjusting unit includes a wall plate member 121 that can be attached to a wall portion (or a side wall portion) by a screw member 130 or the like, and a spiral rod body (screw rod portion) having one end fixed to the wall plate member. ) 122, an advancing / retracting plate member 124 having an insertion hole (an insertion hole having an inner diameter larger than the outer diameter of the spiral rod body 122) 125 through which the spiral rod body can be inserted, and the advancing / retreating plate member 124 and the wall plate It is provided with a nut member 123 that is interposed between the member 121, can be screwed to the spiral rod body 122, and has a corrugated peripheral edge. Therefore, the disk-like nut member 123 can advance and retract the advance / retreat plate member 124 in accordance with advance / retreat (linear motion) associated with the screw engagement with the spiral rod body 122. In addition, the spiral rod body 122 is located in the site | part corresponding to the side edge part of wall attachment part 115b, 116b of the sheet | seat attachment member 115,116 among the said wall plate members 121. FIG. A plurality of helical rod bodies (screw rod portions) 122 are attached to the wall plate member 121 at a predetermined interval in the longitudinal direction. A cylindrical fastening member 126 having an operation portion 127 can be screwed to the distal end portion of the spiral rod body 122 extending from the wall plate member 121, and the front wall of the fastening member is advanced along with the screwing. The wall attachment portions 115b and 116b of the sheet attachment members 115 and 116 can be fastened by the movement. That is, the cylindrical fastening member 126 is formed to have a diameter that can sandwich or fasten the wall mounting portions 115b and 116b with the spiral rod body 122 as the center.

  Further, a guide pin 128 is formed on the advance / retreat plate member 124 so as to protrude, and the guide pin can be inserted along a guide hole 129 formed in the wall attaching portions 115b and 116b. The guide pins 128 and the guide holes 129 are also formed at intervals in the longitudinal direction of the advance / retreat plate member 124 and the wall attachment portions 115b and 116b.

  In such a tension adjusting unit, the disc-shaped nut member 123 is rotated in a state where the end (or side) of the sheet main body 11 is sandwiched between the sheet sandwiching portions 115a and 116a, whereby the spiral rod body 122 is moved. The advancing / retreating plate member 124 and the seat mounting members 115, 116 can be moved back and forth (linearly moved) along. Further, in these operations, the guide pins 128 of the advance / retreat plate member 124 can advance and retract along the guide holes 129 of the wall mounting portions 115b and 116b, so that they can be operated smoothly without being displaced. Therefore, the space | interval of a wall surface and the sheet attachment members 115 and 116 can be adjusted smoothly and efficiently, and the sheet | seat main body 11 can be tensioned. Then, the operation portion 127 of the cylindrical fastening member 126 is rotated and moved forward along the spiral rod body 122, and the wall attachment portions 115 b and 116 b of the sheet attachment members 115 and 116 are fastened by the cylindrical fastening member 126. The seat body 11 can be tensioned and attached to the wall surface.

  Note that the wall plate member is not always necessary, and one end of the spiral rod may be directly fixed to the wall (or side wall). From the viewpoint of workability and the like, it is preferable that one end portion of the spiral rod body is fixed to the wall plate member and indirectly fixed to the wall portion (or side wall portion). The nut member (screwing member) that can be screwed to the spiral rod body does not need to be disk-shaped as described above, and may be capable of moving back and forth along the axis of the spiral rod body as it rotates. . In addition, the sheet can be pulled (pullable in the lateral direction) as the nut member moves forward and backward with respect to the spiral rod body in a state where the end (or side) of the sheet is clamped by the pair of sheet clamping units. The seat may be towable together with the wall attachment portion of the seat attachment member. For example, the advancing / retracting plate member may be integrated with the wall mounting portion of the seat mounting member, and the fastening member is not necessarily required, and at least one of the nut member and the fastening member is screwed (for screwing). Accordingly, a member for pulling the seat may be provided. In addition, the fastening member is not limited to the fastening tubular shape as long as the wall mounting portion can be fastened, and may include a forward portion (front portion or fastening portion) in the form of a plate or the like.

  In the illustrated example, the sheet is stretched or tensioned in the lateral direction by the tension adjusting unit, but the end of the sheet may be stretched or tensioned in the vertical direction according to the attachment form of the sheet. For example, in the case where the regulating portion of the side edge portion, not the upper edge portion of the seat body, can be locked to the retaining recess of the wall mounting member and is accommodated with play, the tension adjusting unit can be the upper wall and / or the lower wall. A tension adjusting unit may be attached to the sheet, and the sheet may be stretched or tensioned in the vertical direction. The tension adjustment unit may be attached to at least one of the pair of seat attachment members, or may be attached to both of the seat attachment members. In addition, when attaching a sheet | seat using a tension | tensile_strength adjustment unit, one edge part of a sheet | seat may be attached not only with the said sheet | seat attachment member but with another attachment member.

  The present invention also includes a construction method for partitioning an indoor space (such as an upper space). In this method, the wall mounting member is attached to the upper wall and / or the side wall, and the sheet slip-out restricting portion is accommodated with play in the retaining recess of the wall mounting member. The partition wall can be efficiently constructed by installing the sheet in the retaining recess in a form in which the slipping of the edge and / or side edge is regulated. In this method, since the sheet is mounted on the wall mounting member after the wall mounting member is mounted on the wall surface (for example, the ceiling wall surface), the workability can be greatly improved. That is, in the method of attaching a wall mounting member to a wall surface (for example, a ceiling wall surface) with the sheet mounted on the wall mounting member, the sheet extending from the wall mounting member is attached to the wall mounting member on the wall surface. This obstructs the installation work and reduces the work efficiency. On the other hand, when the sheet is attached to the wall mounting member after the wall mounting member is mounted on the wall surface (for example, the ceiling wall surface), in addition to the sheet having flexibility, the mounting portion of the wall mounting member However, since it is necessary to attach the seat closely, it is difficult to attach the seat. On the other hand, in the present invention, even after the wall mounting member is mounted on the wall surface, the sheet is inserted at the tip of the pair of extension regulating walls by only inserting the sheet into the retaining recess of the wall mounting member. The slip-off restricting portion can be locked or hooked, and the construction efficiency can be greatly improved.

  In the case of a high strength sheet such as the glass fiber reinforced resin sheet, it is possible to prevent the sheet from wrinkling and wobbling without pulling the sheet from both sides, and the sheet can be spread neatly. Therefore, both sides of the sheet may be separated from the wall surface (for example, both side walls), but may be attached to the wall surface (for example, both side walls). Both side portions of the seat can be attached by various attachment means (brackets), for example, a member (for example, a member having a seat attachment portion (or a sandwiching portion) for a seat and a wall attachment portion for a wall surface (for example, a side wall surface) A sheet mounting member or an angle having an L-shaped cross section can be used. If such a sheet | seat attachment member is used, it can be tensioned and a sheet | seat can be attached efficiently. For example, by using the first seat mounting member, one side portion of the seat body is attached to the seat mounting portion (or sandwiched between the sandwiching portions of the pair of first sheet mounting members), and the first wall mounting portion is After being attached to one wall surface, the second seat attachment member is used, and the other side portion of the seat body is attached to the second seat attachment portion (or sandwiched by the sandwiching portions of the pair of second sheet attachment members). ) By attaching the second wall attachment portion to the other wall surface while pulling the sheet, the sheet can be attached while being tensioned or stretched. The first sheet mounting member and the second sheet mounting member may be installed in advance on both sides of the sheet, respectively, and one side of the sheet may be attached to the first wall by the first sheet mounting member. After attaching to one wall surface by the attaching portion, the second sheet attaching member may be attached to the other side portion of the sheet. In addition, although it is not necessarily required, if the receiving part with respect to a wall attachment member is formed in the 1st sheet attachment member and the 2nd sheet attachment member (upper end part of an attachment member), the aesthetics of a division wall or a division structure can be improved. .

  In addition, you may interpose a joining means (for example, adhesive layer) between a sheet | seat attachment part (or the clamping part of a pair of sheet | seat attachment member) and a sheet | seat. For example, after both side portions of the sheet are bonded to the first and second sheet attachment portions (or the sandwiching portions of the pair of sheet attachment members) with a double-sided adhesive tape, and the first wall attachment portion is attached to one wall surface By attaching the second wall attachment portion to the other side wall while pulling the sheet, the sheet can be attached by spreading the sheet smoothly and efficiently.

  In a preferred partition wall embodiment, the wall mounting member is directly attached to the upper wall (particularly the ceiling wall), and the sheet slip-out restricting portion is in the retaining recess in a form in which the slip-out in the vertical direction is restricted. Contained. The sheet is stretched in the lateral direction. In particular, in the above-described aspect, the partition wall structure is useful as a smoke barrier structure (flame proof wall structure) or a smoke exhaust wall structure.

  The partition wall forming member is used to hold an end portion (for example, a side portion) of the sheet with a sheet clamping portion of a pair of sheet mounting members, and a wall mounting portion extending in an L shape from the sheet clamping portion. You may attach to a wall part (for example, side wall) and construct a division wall.

  In addition, the middle part of the sheet in the longitudinal direction may be sandwiched by an intermediate member (holding member) that sandwiches the sheet from both sides in the longitudinal direction to prevent the sheet from swinging or shaking.

  Also, in an assembly set, smoke barrier or compartment structure, the slip-out restricting portion is formed at one end of the sheet, and a thick portion such as the slip-out restricting portion or a locked portion is formed at the other end. May be. In addition, a load means (a rod-like body or a plate-like body) is used to cause the other end portion (in particular, the lower end portion (lower edge portion) of the sheet) to apply a downward load to stretch the sheet in the vertical direction. May be attached.

  Further, if necessary, at least one side portion of both sides of the sheet is gripped or sandwiched by a gripping member (a pair of sandwiching members), and the gripping member (the pair of sandwiching members is sandwiched between the side portions of the sheet) ) May be fastened by a fastening member such as a screw member, and a screw member as a traction means is screwed to the gripping member via a vertical member (a member fixed in the vertical direction), and the seat May be extended in the lateral direction and a vertical member attached to the end of the gripping member. In addition, a lower bar-shaped member is attached to the lower end of the sheet, and a screw member as a traction means is screwed onto the lower bar-shaped member from below via a lower mounting member (fixed mounting member), thereby lowering the sheet downward. You may pull and stretch. For the extension of the sheet by such a screw member, Patent Documents 6 and 7 can be referred to.

  The present invention can easily and easily attach a wall mounting member (rail member) to a wall surface (particularly, a ceiling wall surface) and attach a sheet to the wall mounting member. It is useful for forming a smoke barrier (smoke-proof hanging wall or smoke-proof partition) or the like. It is also useful for forming shielding curtains (goodwill, etc.) in various spaces (passages, entrance / exit spaces, etc.).
