Description

[Technical field]

[0001] The present invention relates to an aperture frame. [Background technology]

[0002] There are various regulations for buildings and other structures according to the Building Standards Act. Buildings that require smoke exhaust equipment are those with a floor area of ​​500 m or more. 2 In addition, within the smoke-proof area, a smoke-proof wall that hangs down from the ceiling must be installed within 30 meters of the smoke exhaust port.

[0003] Incidentally, a relatively large indoor space such as an office may be partitioned into a plurality of spaces, and each space may be used for a different purpose. As an example, there is an aspect in which a floor-to-ceiling partition panel and a floor-to-ceiling door are installed in a manner connected to the partition panel, as disclosed in the first embodiment of Patent Document 1. However, the aspect of the first embodiment of Patent Document 1 is not suitable as a smoke-proof section. On the other hand, the aspect disclosed in FIG. 8 of the second embodiment of Patent Document 1 includes a transom panel 109 in which a rectangular surface material, a plate glass 195, is held at its outer periphery by a frame material, and can function as a smoke-proof hanging wall, and therefore is applicable to a smoke-proof section. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2020-200710 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the aspect disclosed in Fig. 8 of the second embodiment of the above-mentioned Patent Document 1, the lower structure of the transom panel 109, in which the outer periphery of the glass sheet 195 is held by a frame material, and the upper structure of the frame that fixes the door located directly below are arranged side by side, and the arranged parts have a visually significant presence, resulting in a problem that the appearance is inferior. Also, the arrangement of the transom panel 109 limits the height of the door (height from the floor to the ceiling).

[0006] Therefore, the object of the present invention is to realize an opening frame that can be used as a smokeproof section by installing a smokeproof hanging wall even when a fixture (e.g., a door) that has a height from the floor to the ceiling is installed. [Means for solving the problem]

[0007] In order to solve the above problems, an opening frame according to one embodiment of the present invention is an opening frame connected to a partition wall that divides an indoor space, and includes a pair of vertical frames erected between the floor surface and the ceiling surface and spaced a predetermined distance apart in the horizontal direction, a fitting having a height from floor to ceiling and arranged between one and the other of the pair of vertical frames, and a smokeproof hanging wall arranged so as to hang down from the ceiling surface between one and the other of the pair of vertical frames, and is characterized in that the fitting and the smokeproof hanging wall are arranged in a position where they overlap in the front-to-back direction between one and the other of the pair of vertical frames. Effect of the Invention

[0008] According to one aspect of the present invention, even when a fixture (e.g., a door) having a height from the floor to the ceiling is placed, a smokeproof hanging wall can be installed, thereby realizing an opening frame that can be used as a smokeproof section. [Brief description of the drawings]

[0009] [Figure 1] 1 is a front view of a partition unit including an opening frame in one embodiment of the present invention. FIG. [Diagram 2] 2 is a cross-sectional view taken along line AA in FIG. 1. [Diagram 3] FIG. 3 is an enlarged cross-sectional view of the enclosed portion of FIG. 2. [Figure 4] 2 is a cross-sectional view taken along line DD in FIG. 1. [Diagram 5] FIG. 5 is an enlarged cross-sectional view of the enclosed portion of FIG. 4. [Figure 6] 2 is a cross-sectional view taken along line BB shown in FIG. 1. [Figure 7] 13 is a perspective view of a partition unit including an opening frame in another embodiment of the present invention. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] [Embodiment 1] The opening frame in one embodiment of the present invention will be described below. FIG. 1 is a front view showing an opening frame 10 and a partition wall 20 to which the opening frame 10 is connected. The partition wall 20 partitions an indoor space. The opening frame 10 connected to the partition wall 20 also constitutes a partition unit 30 that partitions the indoor space together with the partition wall 20. The partition unit 30 can form a wall by being arranged in a place where there is no wall in the indoor space. The partition unit 30 can partition the indoor space, and is composed of three components arranged in the order of the partition wall 20, the opening frame 10, and the partition wall 20 from the left side to the right side of the paper, but the present invention is not limited to this. In the example of the partition unit 30 in FIG. 1, the partition walls 20 are arranged on both the left and right sides of the paper, sandwiching the opening frame 10. However, this is not limited to the above, and the partition wall 20 may be arranged on only one side of the opening frame 10, either on the left side of the paper or on the right side of the paper, and no partition wall may be connected to the other side, and the wall of the room may be located there.

[0011] In the example of Fig. 1, the partition wall 20 is configured such that a glass wall material 21 having a wall surface extending vertically from the floor surface to the ceiling surface is held by a frame body 22 that holds the outer periphery of the glass wall material 21. A ground rail 41 constituting the lower end edge of the partition unit 30 is installed on the floor surface 40, and a top rail 51 constituting the lower end edge of the partition unit 30 is installed on the ceiling surface 50. The lower end edge of the partition wall 20 is connected to the ground rail 41, and the upper end edge of the partition wall 20 is connected to the top rail 51. The ground rail 41 is continuous along the opening frame 10 and the partition walls 20 on both sides thereof, and the top rail 51 is also continuous along the opening frame 10 and the partition walls 20 on both sides thereof.

[0012] The opening frame 10 includes a pair of vertical frames 11, 12 (a first vertical frame 11 and a second vertical frame 12), a horizontal frame 13, a door 6 (fitting), and a smoke barrier hanging wall 7. In an embodiment in which partition walls 20 are arranged on both the left and right sides of the opening frame 10 as shown in the example of Fig. 1, the first vertical frame 11 may be a vertical frame shared between the opening frame 10 and the partition wall 20 on the left side of the page, and the second vertical frame 12 may be a vertical frame shared between the opening frame 10 and the partition wall 20 on the right side of the page.

[0013] A pair of vertical frames 11, 12 (first vertical frame 11 and second vertical frame 12) are erected between the floor surface 40 and the ceiling surface 50, with a predetermined gap between them in the horizontal direction. The distance between the first vertical frame 11 and the second vertical frame 12 is the opening width. The horizontal frame 13 is disposed along the ceiling surface 50, between the first vertical frame 11 (one vertical frame) and the second vertical frame 12 (the other vertical frame).

[0014] Fig. 2 is a cross-sectional view taken along the line AA shown in Fig. 1. As shown in Fig. 2, the first vertical frame 11 and the second vertical frame 12 are each rectangular in top view, and have first side surfaces 11a, 12a where the vertical frames face each other, second side surfaces 11b, 12b facing forward, third side surfaces 11c, 12c facing rearward, and fourth side surfaces 11d, 12d located on the back side of the first side surfaces 11a, 12a.

[0015] The first vertical frame 11 has four side surfaces, a first side surface 11a, a second side surface 11b, a third side surface 11c, and a fourth side surface 11d, which form the four side surfaces when viewed from above. The first vertical frame 11 has a first recessed portion 11e on the second side surface 11b facing forward. The first recessed portion 11e is an L-shaped recess when viewed from above, which is provided at the boundary between the first side surface 11a and the second side surface 11b. The first recessed portion 11e extends from the floor to the ceiling.

[0016] The second vertical frame 12 has four side surfaces, a first side surface 12a, a second side surface 12b, a third side surface 12c, and a fourth side surface 12d, in a top view. The second vertical frame 12 has a first recessed portion 12e in the second side surface 12b facing forward. The first recessed portion 12e is an L-shaped recess in a top view provided at the boundary between the first side surface 12a and the second side surface 12b. The first recessed portion 12e extends from the floor to the ceiling.

[0017] The door 6 is an example of a fixture having a height from the floor surface 40 to the ceiling surface 50, and is disposed between the first vertical frame 11 and the second vertical frame 12. In this embodiment, since the horizontal frame 13 is provided on the ceiling surface 50, the height of the door 6 is a height from a position substantially the same as the floor surface 40 to the position of the horizontal frame 13 disposed along the ceiling surface 50, but this door 6 is also included in the "fixture having a height from the floor to the ceiling" in the claims. In the example of FIG. 2, the door 6 is disposed between the first recessed portion 11e of the first vertical frame 11 and the first recessed portion 12e of the second vertical frame 12.

[0018] The door 6 is disposed between a first vertical frame 11 and a second vertical frame 12, and rotates around a rotation shaft 60 located near the second vertical frame 12. FIGS. 1 and 2 show the door 6 in a closed state. In short, in the state shown in FIGS. 1 and 2, the space between the first vertical frame 11 and the second vertical frame 12 is closed by the door 6, and people cannot pass between the first vertical frame 11 and the second vertical frame 12. On the other hand, when the door 6 rotates around the rotation shaft 60 and is no longer disposed between the first vertical frame 11 and the second vertical frame 12, the space between the first vertical frame 11 and the second vertical frame 12 is opened, and people can pass between them.

[0019] Here, the components of the door 6 will be described. The door 6 is configured such that the outer periphery of a main body 61 made of a transparent material is held by a frame body 62 (Fig. 1). The main body 61 made of a transparent material can be made of glass, as an example. However, the door main body 61 is not limited to being made of a transparent material. One example of a material that is not a transparent material is steel. When the door main body is made of steel, the hanging smoke barrier 7 cannot be seen when looking at the door from the side without the hanging smoke barrier, which provides a good design.

[0020] The main body 61 made of a transparent material is a plate-like member having a rectangular shape when viewed from the front. Each of the four edges of the plate-like main body 61 is held by a frame member 63, and the frame members 63 are connected to each other to form a rectangular frame body 62. Each of the frame members 63 has a groove formed on the side surface facing each other, and the edge of the main body 61 made of a transparent material fits into this groove.

[0021] The frame members 63 arranged on both sides of the transparent body 61 shown in Fig. 2 are vertical frame members 63 extending vertically from the floor surface to the ceiling surface. As shown in Fig. 2, when the door 6 is fitted into the first recessed portion 11e of the first vertical frame 11 and the first recessed portion 12e of the second vertical frame 12, the front-facing surfaces of these vertical frame members 63 are configured to be substantially flush with the second side surface 11b of the first vertical frame 11 and the second side surface 12b of the second vertical frame 12. This results in a flat appearance when the front surface of the door 6 in the state shown in Fig. 2 is viewed from a side further forward than the door 6, giving a stylish impression.

[0022] When the door 6 is in a state in which the space between the first vertical frame 11 and the second vertical frame 12 is closed as shown in Fig. 2, the rear surface of the first recessed portion 11e of the first vertical frame 11 is positioned to face the rear surface of the vertical frame member 63 on the leading edge side of the door 6, and the rear surface of the first recessed portion 12e of the second vertical frame 12 is positioned to face the rear surface of the vertical frame member 63 on the trailing edge side of the door 6. This makes it possible to suppress light leakage and sound leakage from the leading edge side and trailing edge side of the door 6 when the door 6 is viewed from the rear side in the state shown in Fig. 2. Note that one aspect of the present invention is not limited to the aspect in which the door 6 and the pair of vertical frames 11, 12 of the opening frame 10 overlap at the leading edge side and trailing edge side of the door.

[0023] As shown in FIG. 1, the smokeproof hanging wall 7 is arranged between the first vertical frame 11 and the second vertical frame 12 so as to hang down from the ceiling surface 50, and the smokeproof hanging wall 7 is arranged in a position overlapping with the door 6 in the front-to-back direction (Y-axis direction) when the door 6 is arranged between the first vertical frame 11 and the second vertical frame 12.

[0024] 2, the hanging smoke barrier 7 is disposed so as to be sandwiched between the first vertical frame 11 and the second vertical frame 12. The width (length in the X-axis direction) of the hanging smoke barrier 7 and the width (length in the X-axis direction) of the door 6 are substantially the same, in other words, the entire width of the area of ​​the door 6 closer to the ceiling surface 50 is covered by the hanging smoke barrier 7. Specifically, the door 6 is disposed on the front side and the hanging smoke barrier 7 on the rear side so that the rearward facing surface of the door 6 and the forward facing surface of the hanging smoke barrier 7 face each other.

[0025] Unlike the door 6, the smokeproof hanging wall 7 does not move from between the first vertical frame 11 and the second vertical frame 12, but hangs down a specified length from the ceiling surface 50 to seal the gap between the first vertical frame 11 and the second vertical frame 12. Because the smokeproof hanging wall 7 is configured in this way, it can turn the opening frame 10 into a smokeproof compartment.

[0026] The smoke barrier hanging wall 7 is attached to the first vertical frame 11 and the second vertical frame 12 (not attached to the horizontal frame 13), or is not attached to the first vertical frame 11 and the second vertical frame 12 but is attached to the horizontal frame 13 ( FIG. 1 ), or is attached to the first vertical frame 11, the second vertical frame 12, and the horizontal frame 13. In this embodiment, an example in which the smoke barrier hanging wall 7 is attached to the first vertical frame 11, the second vertical frame 12, and the horizontal frame 13 will be described.

[0027] Here, the first vertical frame 11 and the second vertical frame 12 will be further described with reference to FIG. 2. As shown in FIG. 2, the first vertical frame 11 has a second recessed portion 11f on the third side surface 11c facing backward. The second recessed portion 11f is an L-shaped recess in top view provided at the boundary between the first side surface 11a and the third side surface 11c. The second recessed portion 11f extends from the floor to the ceiling. The second vertical frame 12 has a second recessed portion 12f on the third side surface 12c facing backward. The second recessed portion 12f is an L-shaped recess in top view provided at the boundary between the first side surface 12a and the third side surface 12c. The second recessed portion 12f extends from the floor to the ceiling.

[0028] The hanging smoke barrier 7 is disposed so as to fit into the second recessed portion 11f of the first vertical frame 11 and the second recessed portion 12f of the second vertical frame 12. Here, Fig. 3 is an enlarged view of the area P enclosed by the dashed line in Fig. 2. Fig. 3 shows only the first vertical frame 11 side, but the second vertical frame 12 is symmetrical and has the same aspect. As shown in Fig. 3, the hanging smoke barrier 7 includes a hanging smoke barrier main body 71 made of a transparent material that transmits light from a wall surface facing forward (front wall surface) to a wall surface facing backward (rear wall surface), and an attachment portion 72 for attaching the hanging smoke barrier 7 (hanging smoke barrier main body 71) to the first vertical frame 11.

[0029] The hanging smoke barrier main body 71 is a plate-like structure arranged to fit into the second recessed portion 11f of the first vertical frame 11 and the second recessed portion 12f of the second vertical frame 12, and has a rectangular shape when viewed from the front. The hanging smoke barrier main body 71 is made of a non-combustible material, and its thickness (length along the Y-axis direction) is not particularly limited. As an example, the hanging smoke barrier main body 71 can be made of a rectangular plate-like glass. However, the hanging smoke barrier main body 71 is not limited to glass, and does not have to be transparent. As an example, the hanging smoke barrier main body 71 may be a steel plate, and any material is acceptable.

[0030] As shown in FIG. 3, the smokeproof hanging wall main body 71 is accommodated in the second recessed portion 11f of the first vertical frame 11. Since the smokeproof hanging wall main body 71 is made of a transparent material, while the first vertical frame 11 is not made of a transparent material, when the smokeproof hanging wall 7 is viewed from the front side from the rear side, the area facing the front surface of the second recessed portion 11f is blocked from light. This is also true for the second vertical frame 12 side shown in FIG. 2. Therefore, when the smokeproof hanging wall main body 71 is viewed from the front side from the rear side, the light passes between the first side surface 11a of the first vertical frame 11 and the first side surface 12a of the second vertical frame 12. When the door 6 is in a closed state as shown in FIG. 2 and FIG. 3, the vertical frame body 63 (frame member 62) of the door 6 is visible from the rear side through the smokeproof hanging wall main body 71 made of a transparent material.

[0031] The mounting portion 72 is provided on the periphery of the rectangular plate-shaped smoke barrier hanging wall main body 71, and is made of a metal material (e.g., stainless steel) as an example. Specifically, the mounting portion 72 is disposed in the portion where the first vertical frame 11, which is not made of a transparent material as described above, and the smoke barrier hanging wall main body 71 overlap with each other.

[0032] As an example, the mounting portion 72 is adhesively fixed to the hanging smoke barrier main body 71 with an adhesive. In order to ensure a wide adhesion area to the hanging smoke barrier main body 71, the mounting portion 72 is configured by bending a metal plate as shown in Fig. 3, and extends from the rearward surface of the hanging smoke barrier main body 71 to the surface facing the second recessed portion 11f, and further extends to a location facing the first side surface 11a of the first vertical frame 11. At this location, the mounting portion 72 is fixed to the first vertical frame 11 with screws 73.

[0033] As an example, the mounting portion 72 is disposed over the entire length of the edge along the Y-axis direction of the smoke barrier hanging wall main body 71. In this case, there may be a plurality of fixing points to the first vertical frame 11 by the screws 73 along the Y-axis direction. In addition to the fixing method using the screws 73, it is also possible to adhesively fix the portion facing the second recessed portion 11f with an adhesive.

[0034] As shown in Figs. 2 and 3, when the smoke barrier hanging wall 7 having such a configuration is fitted into the second recessed portion 11f of the first vertical frame 11 and the second recessed portion 12f of the second vertical frame 12, the rearward-facing surface of the smoke barrier hanging wall 7 does not protrude rearward beyond the third side surface 11c of the first vertical frame 11 and the third side surface 12c of the second vertical frame 12. This can be achieved by configuring the depth of the recess along the Y-axis direction of the second recessed portions 11f, 12f and the thickness of the smoke barrier hanging wall 7 to be approximately equal. Note that the third side surfaces 11c, 12c and the rearward-facing surface of the smoke barrier hanging wall 7 do not have to be completely flush with each other. Since neither of them protrudes significantly, when the rear surface of the opening frame 10 in the state of Fig. 2 is viewed from the rear side, the appearance is flat, giving a stylish impression.

[0035] 4 is a cross-sectional view taken along the line DD in FIG. 1. As shown in FIG. 4, the front-facing surface of the upper frame member 62 of the door 6 and the front-facing second side surface 13b of the horizontal frame 13 are substantially aligned in the vertical direction (Z-axis direction), resulting in a flat appearance and a stylish impression. As shown in FIG. 4, the horizontal frame 13 is also provided with a first recessed portion 13e into which the door 6 fits and a second recessed portion 13f into which the smoke barrier 7 fits, similar to the pair of vertical frames 11 and 12. A damper (sometimes called a door closer) is installed inside the horizontal frame 13 to gently open and close the door 6.

[0036] 5 is an enlarged view of the area Q enclosed by the dashed line in FIG. 4. As shown in FIG. 5, the hanging smoke barrier 7 includes a mounting portion 72 for mounting the hanging smoke barrier main body 71 to the horizontal frame 13. The mounting portion 72 may be integral with the mounting portion 72 for mounting the hanging smoke barrier 7 (hanging smoke barrier main body 71) to the pair of vertical frames 11, 12 described above, or may be formed as a separate body. The mounting portion 72 shown in FIG. 5 also has a curved shape like the mounting portion 72 described above, and extends from the rearward surface of the hanging smoke barrier main body 71 to the surface facing the second recessed portion 13f, and further extends to a portion facing the first side surface 13a of the horizontal frame 13. At this portion, the mounting portion 72 is fixed to the horizontal frame 13 by a screw 73.

[0037] Here, the lower end in the vertical direction of the hanging smoke barrier 7 shown in FIG. 1 and FIG. 4 may be composed of only the hanging smoke barrier main body 71, or may be an extension of the mounting part 72 attached to the pair of vertical frames 11, 12, or may be provided with a configuration different from the mounting part. The separate configuration may be a cover covering the lower end of the hanging smoke barrier main body 71 or a cushioning material that absorbs impact in the event of a collision. In other words, no frame material is fixed to the lower end (second end) of the hanging smoke barrier 7 that extends along the floor surface. Since no frame material is fixed, there is no frame material in the middle position from the floor to the ceiling, and compared to the case where there is a frame material in the middle position, the appearance from the floor to the ceiling can be given a simple and stylish impression. This is because even when the door 6 is in an open state, although there is the hanging smoke barrier 7, there is no frame material that blocks the view in the middle of the space between the opening frame 10, which makes the appearance good.

[0038] Fig. 6 is a cross-sectional view taken along the line BB in Fig. 1. There is no smoke barrier 7 at the position of the line BB in Fig. 1. The door 6 and the pair of vertical frames 11, 12 will be further described with reference to Fig. 6. Note that an auxiliary line extending diagonally on the door 6 is shown in Fig. 1, but this auxiliary line indicates the opening and closing direction of the door 6.

[0039] The door 6 is provided with a handle 64 (sometimes called a doorknob or door handle) on a vertical frame member 63 on the door end side, which is used when opening and closing the door 6. The handle 64 is provided on both the front and rear sides of the door 6. In this example, the handle 64 extends long in the vertical direction, but this is not limited to the embodiment. The door 6 is provided with a lock part 65 below the handle 64 for locking the door. It is also possible to adopt a handle 64 with a locking function.

[0040] The second recesses 11f, 12e are also provided in the pair of vertical frames 11, 12 in a position where the smoke barrier hanging wall 7 shown in FIG. 6 is not present.

[0041] Here, the smoke barrier wall 7 is attached removably by attaching and removing the above-mentioned screw 73. The second recesses 11f, 12f, and 13f provided in the pair of vertical frames 11 and 12 and the horizontal frame 13 described above are formed over the entire length of the frames, so that the opening frame 10 does not lose its design even when the smoke barrier wall 7 is removed. In addition, the opening frame 10 can be made common between the specification when the smoke barrier wall 7 is not required and the specification when the smoke barrier wall 7 is installed, and in terms of manufacturing costs, for example, costs can be reduced in addition to the case where a different opening frame must be prepared for each design.

[0042] As described above, according to the opening frame 10 of the present embodiment, the door 6 having a height from the floor to the ceiling and the hanging smoke barrier 7 are configured to overlap in the front-rear direction at the space between the pair of vertical frames 11, 12. Therefore, even when the door is open, the hanging smoke barrier 7 is arranged in a state of hanging down from the ceiling surface. This allows the opening frame 10 equipped with the door 6 to be a smoke-proof section. In addition, the door 6 having a height from the floor to the ceiling can be installed in the smoke-proof section, which makes it easy to improve the design. In addition, there is no need to separately prepare a frame body for installing the hanging smoke barrier 7 and a frame body for the door 6, and one opening frame can be used for both installing the door 6 and installing the hanging smoke barrier 7.

[0043] (Modification) In the above embodiment, the opening frame 10 is exemplified as having the horizontal frame 13 along the ceiling surface 50, but the horizontal frame 13 may be omitted. When the horizontal frame 13 is omitted, the smoke barrier hanging wall 7 is fixed to a pair of vertical frames 11, 12. In this example, the door 6 has a height from the floor surface 40 to the ceiling surface 50.

[0044] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals are given to members having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0045] In the above-mentioned embodiment 1, the opening frame 10 equipped with the door 6 which is a hinged door has been described, but the present invention is not limited thereto. The present embodiment shown in Fig. 7 differs from embodiment 1 in that the fitting equipped in the opening frame 10A is a sliding door 6A. Fig. 7 will be described below.

[0046] 7 is a perspective view of a partition unit 30A including an opening frame 10A of this embodiment and a partition wall 20 connected to the opening frame 10A. The opening frame 10A is provided with a sliding door 6A that closes the space between the pair of vertical frames 11, 12. A horizontal frame 13 is disposed between the pair of vertical frames 11, 12 along the ceiling surface.

[0047] The sliding door 6A has a height from the floor surface to the ceiling surface, and slides horizontally. A well-known mechanism can be adopted as the sliding mechanism. In the case of the opening frame 10 of this embodiment, the vertical frame 12 on the door end side of the pair of vertical frames 11, 12 is provided with a recess (not shown) similar to the first recess 12e (FIG. 2) described above, into which the door end of the sliding door 6A can be fitted.

[0048] The pair of vertical frames 11, 12 are provided with second recesses 11f, 12f, to which the hanging smoke barrier 7 is fixed. The hanging smoke barrier 7 is also fixed to the second recess 13f in the horizontal frame 13. The manner of fixing can be the same as that described in the first embodiment, and therefore description thereof will be omitted here.

[0049] Here, the sliding door 6A is configured such that the outer periphery of a main body 61 made of a transparent material is held by a frame body 62 (FIG. 1) in the same manner as the door 6 in the embodiment 1. The main body 61 made of a transparent material is made of glass, for example, and the frame body 62 is made of aluminum, for example.

[0050] Furthermore, a horizontal bar 68 is provided at about the middle height of the sliding door 6A. The horizontal bar 68 is not configured to structurally divide the main body 61 made of a transparent material, but is configured to be attached and fixed to each of the front and back surfaces of the main body 61 made of a transparent material. As an example, the horizontal bar 68 can be attached to each of the front and back surfaces of the main body 61 made of a transparent material using double-sided tape. The horizontal bar 68 may also be attached to the glass wall material 21 of the partition wall 20. Note that, although only one horizontal bar 68 is provided in the example of FIG. 7, a configuration in which two or more horizontal bars are arranged in parallel may also be used.

[0051] In the opening frame 10A of this embodiment, similarly to the opening frame 10 of the above-mentioned embodiment 1, the sliding door 6A having a height from the floor to the ceiling and the hanging smoke barrier 7 are configured to overlap in the front-to-rear direction in the space between the pair of vertical frames 11, 12. Therefore, even when the sliding door 6A is open, the hanging smoke barrier 7 is arranged in a state of hanging down from the ceiling surface. This allows the opening frame 10A equipped with the sliding door 6A having a height from the floor to the ceiling to be a smoke barrier section.

[0052] Here, each of the pair of vertical frames 11, 12 and horizontal frame 13 may have a structure in which decorative material is attached to the surface of a frame body as a skeleton. Each frame has a rectangular column structure when viewed from the outside, and the detailed structure will be described later, but the material constituting the frame body can be a well-known building material for partitions. As an example, an aluminum frame body can be used. As the decorative material, a wood-like decorative material can be used as an example. Each frame with the wood-like decorative material attached can give the appearance of being made of wood. The horizontal rail 68 can also be configured in a similar manner.

[0053] [Additional Note 1] The opening frame of aspect 1 of the present invention is an opening frame connected to a partition wall that divides an indoor space, and includes a pair of vertical frames erected between the floor surface and the ceiling surface and spaced a predetermined distance apart in the horizontal direction, a fitting having a height from floor to ceiling and arranged between one and the other of the pair of vertical frames, and a smokeproof hanging wall arranged so as to hang down from the ceiling surface between one and the other of the pair of vertical frames, and the fitting and the smokeproof hanging wall are arranged in a position where they overlap in the front-to-back direction between one and the other of the pair of vertical frames.

[0054] According to the first aspect, a fixture (e.g., a door) having a height from floor to ceiling and a hanging smoke barrier are overlapped in the front-to-rear direction in the space between a pair of vertical frames. Therefore, for example, when the fixture is a hinged door or a sliding door, even when the door is open, the hanging smoke barrier is arranged in a state of hanging down from the ceiling surface. Thus, according to the above configuration, an opening frame equipped with a fixture having a height from floor to ceiling can be made into a smoke barrier section.

[0055] In addition, even in smokeproof compartments, fittings with floor-to-ceiling height can be installed, making it easier to improve design.

[0056] In addition, there is no need to prepare a frame for installing the smokeproof hanging wall and a frame for the fixture (e.g., for a door) separately, and one opening frame can be used for both installing the door and the smokeproof hanging wall.

[0057] The opening frame of aspect 2 of the present invention is the same as aspect 1, and includes a horizontal frame arranged along the ceiling surface between one and the other of the pair of vertical frames, and the smoke barrier hanging wall is attached to the pair of vertical frames, or to the horizontal frame, or to the pair of vertical frames and the horizontal frame.

[0058] According to the second aspect, the smoke barrier hanging wall is attached to at least one of a pair of vertical frames or horizontal frames.

[0059] The opening frame of aspect 3 of the present invention is configured such that, in aspect 1 or 2, each of the pair of vertical frames has a rectangular shape when viewed from above, and each of the pair of vertical frames has a first side where the vertical frames face each other, a second side facing forward, and a third side facing rearward, the building fixture is accommodated in a first recessed portion extending from the floor to the ceiling on the second side of each of the vertical frames, and the smoke barrier hanging wall is accommodated in a second recessed portion extending from the floor to the ceiling on the third side of each of the vertical frames.

[0060] According to the above-mentioned aspect 3, both the fittings and the smoke barrier hanging wall are fitted within the width of the vertical frame of the opening frame, so that the second side surface of the vertical frame and the fittings provide a nearly flat appearance, and the third side surface of the vertical frame and the smoke barrier hanging wall provide a nearly flat appearance, thereby achieving a stylish exterior.

[0061] The opening frame of aspect 4 of the present invention is any of aspects 1 to 3, wherein the smoke barrier hanging wall has a first end extending along the ceiling surface and a second end extending along the floor surface arranged opposite each other, and no frame material is fixed to the second end.

[0062] According to the above-mentioned aspect 4, since no frame material is fixed to the second end portion of the smoke barrier hanging wall that extends along the floor surface, there is no frame material halfway between the floor and the ceiling, which gives a simpler and more stylish appearance from the floor to the ceiling compared to when there is a frame material halfway between the floor and the ceiling.

[0063] The opening frame according to aspect 5 of the present invention is any one of aspects 1 to 4, in which the smoke barrier hanging wall is removably attached.

[0064] According to the fifth aspect, the opening frame can be made common between the specification when the hanging smoke barrier is not required and the specification when the hanging smoke barrier is installed. This can reduce manufacturing costs, for example, in addition to the case where a different opening frame must be prepared for each design.

[0065] The opening frame of aspect 6 of the present invention is any of aspects 1 to 5, wherein the fixture is a door that has a height from floor to ceiling and rotates around a rotation axis located near one of the pair of vertical frames.

[0066] According to the sixth aspect, when the door is closed, the door and the hanging smoke barrier overlap, and even when the door is open, the hanging smoke barrier is positioned near the ceiling of the vertical frame, and people can pass through the opening provided below the hanging smoke barrier.

[0067] The opening frame of aspect 7 of the present invention is any of aspects 1 to 6, wherein the fixture is configured such that the outer periphery of a main body of transparent material is held by a frame body, and the smoke barrier hanging wall is provided with a transparent material that allows light to pass from the front wall surface to the back wall surface.

[0068] According to the seventh aspect, even when the fitting and the smoke barrier are overlapped, transparency is ensured, giving the impression that only a transparent door is present.

[0069] [Additional Note 2] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
