DETAILED DESCRIPTION OF THE INVENTION

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In some drawings, some of the detailed reference numerals used in other drawings are omitted. In the following embodiment, directions such as the up-down direction will be described based on the state in which an example of the partition wall device according to this embodiment is installed. 1 to 6 are diagrams that schematically show an example of a partition wall device according to this embodiment and an example of a partition wall construction method according to this embodiment.

[0011] As shown in Figures 1 and 2, a partition wall device 1 according to this embodiment has a door frame 7 installed on one side in the wall width direction. This partition wall device 1 includes a partition panel 10 in which a plate-like member 11 is provided within a four-perimeter frame (four-perimeter frame) 12, and the lower end is fixed to the floor 4 and the upper end is fixed to the ceiling 3. With this configuration, the lower end of the partition panel 10 can be fixed to the floor 4 and the upper end of the partition panel 10 can be fixed to the ceiling 3 with the plate-like member 11 provided within the four-perimeter frame 12, improving workability. The partition wall device 1 is provided with a trim frame 20 whose dimension along the wall thickness direction is greater than the dimension along the wall thickness direction of the vertical frame 15 of the partition panel 10, and which is fixed to the partition panel 10 by fasteners 9 so as to be along the vertical frame 15 on one side in the wall width direction. The vertical frame (door-front vertical frame) 7b of the door frame 7 is fixed to the trim frame 20 on the side opposite the partition panel 10 in the wall width direction.

[0012] With the above-described configuration, the partition panel 10 can be installed in a state where it is separated from the door frame 7 to which the door body 8 is attached via the trim 20, thereby improving the flexibility of selecting the partition panel 10 to be installed on the side of the door frame 7. The trim 20 also improves the fixing strength of the leading-edge vertical frame 7b of the door frame 7. For example, if the leading-edge vertical frame 7b of the door frame 7 is fixed directly to the vertical frame 15, the dimension of the vertical frame 15 along the wall thickness direction is smaller than the general wall thickness, which could result in the non-decorative surface of the back side of the leading-edge vertical frame 7b being exposed. With the above-described configuration, the dimension of the trim 20 along the wall thickness direction is larger than the dimension of the partition panel 10 along the wall thickness direction of the vertical frame 15, so the non-decorative surface of the back side of the leading-edge vertical frame 7b of the door frame 7 can be covered by the trim 20. An example of a specific configuration of the partition panel 10 and the trim 20 will be described later.

[0013] The partition wall device 1 and door frame 7 are installed in an opening 2 (see also FIG. 4(a)) provided in a building. The illustrated example shows an example in which multiple partition panels 10, 10 (two in the illustrated example) are installed in the opening 2 in the wall width direction, along with a trim frame 20 and a door frame 7. The partition wall device 1 may also include a door frame 7 and a door body 8. The opening 2 may be defined by a ceiling 3 on the upper side and a floor 4 on the lower side, a first wall 5 on one side in the width direction of the opening where the partition panel 10 is to be installed, and a second wall 6 on the other side in the width direction of the opening where the door frame 7 is to be installed. The ceiling 3 is not limited to a finished ceiling surface and may be a ceiling subsurface (frame subsurface). The floor 4 is not limited to a finished floor surface and may be a subsurface (frame subsurface). The first wall 5 may be a wall surface of a wall disposed perpendicular to the wall width direction of the partition wall device 1, and this wall surface may be a finished wall surface or a subsurface. The second wall 6 may be an end surface of a wall disposed on the door frame 7 side in the wall width direction of the partition wall device 1 so that the center of the wall thickness direction coincides with the center of the wall thickness direction of the partition wall device 1, and this end surface may be a frame subsurface.

[0014] The door frame 7 comprises an upper frame 7a that is fixed to an upper frame base such as a ceiling base that is fixed to the ceiling 3 side so as to fit along the ceiling 3, a door-end vertical frame 7b, and a hanging-side vertical frame 7c that holds the door body 8 rotatably (openable and closable). The door-end vertical frame 7b is provided with a latch receiver that receives a latch provided on the door body 8. The illustrated example shows an example in which the door frame 7 is installed so that the door-end vertical frame 7b faces the partition panel 10. In other words, this door-end vertical frame 7b is fixed so as to fit along the trim frame 20. With this configuration, the hanging-side vertical frame 7c, which is relatively heavily loaded in order to hold the door body 8 rotatably, can be stably fixed to a vertical frame base such as a wall base. The door-end side vertical frame 7b may be fixed to the trim frame 20 with fasteners 9 such as screws fastened to the trim frame 20 via the groove bottom of the mounting groove where the door stop member is attached. In this case, the fasteners 9 may be fastened to the trim frame 20 at multiple locations spaced apart along the longitudinal direction of the door-end side vertical frame 7b. The hanging side vertical frame 7c may also be fixed along the second wall portion 6 in a similar manner with fasteners 9 fastened to the second wall portion 6 via the groove bottom of the mounting groove. The door frame 7 may be assembled into a three-sided frame by joining the leading-side vertical frame 7b and the hanging-side vertical frame 7c to each longitudinal end of the upper frame 7a, and then fixed to the ceiling 3, the trim frame 20, and the second wall 6. In the illustrated example, the door body 8 is configured with a translucent plate-like member similar to the plate-like member 11, within a four-sided frame having vertical stiles on both sides of the door width, an upper stile between the upper ends of these vertical stiles, and a lower stile between the lower ends of these vertical stiles. Also shown is an example in which a lever-shaped handle is provided at the leading-side end of the door body 8. The hanging-side end of the door body 8 is connected to the hanging-side vertical frame 7c via a hinge so as to be rotatable around an axis extending in the vertical direction. The door body 8 is not limited to this configuration, and various other configurations may be used.

[0015] As shown in FIG. 2 , the trim frame 20 is configured to be fixed along the vertical frame 15 by fasteners 9 that are fastened via a portion on one side in the wall thickness direction relative to the plate-like member 11 in the vertical frame 15 on one side of the wall width direction of the partition panel 10. With this configuration, after the partition panel 10 is installed, the trim frame 20 can be easily fixed by fastening the fasteners 9 from the vertical frame 15 side of the partition panel 10. The vertical frame 15 on one side in the wall width direction is hollow and cylindrical, and a head insertion hole 15b through which the head of the fastener 9 is inserted is provided in a side wall portion on the inner periphery of the panel. With this configuration, the fasteners 9 can be inserted through the head insertion hole 15b in the side wall portion on the inner periphery of the vertical frame 15 and easily fastened to the trim frame 20. Furthermore, because the heads are disposed within the vertical frame 15, the fasteners 9 can be made less noticeable. The vertical frame 15 on the other side of the partition panel 10 in the wall width direction is hollow and cylindrical, and a head insertion hole 15b through which the head of the fastener 9 is inserted is provided in the side wall portion on the inner periphery of the panel. In other words, the vertical frames 15 on both sides in the wall width direction are each provided with a head insertion hole 15b. With this configuration, the trim frame 20 can be easily fixed to either side of the partition panel 10 in the wall width direction. Furthermore, when connecting multiple partition panels 10 in the wall width direction, one of the head insertion holes 15b can also be used as an insertion hole for the fastener 9 to be attached to the vertical frame 15 of the adjacent partition panel 10.

[0016] Specifically, the frame 20 is elongated in the vertical direction as shown in Figure 1. The dimension of the frame 20 in the vertical direction is approximately the same as the dimension of the door frame 7 (front-end vertical frame 7b) in the vertical direction. The frame 20 is in the shape of a strip of wood arranged so that its thickness direction is the wall width direction. The thickness dimension (visible dimension) of the trim frame 20 may be an appropriate dimension from the viewpoint of ensuring the fixing strength of the door-end vertical frame 7b to which it is fixed, from the viewpoint of appearance, etc., and may be, for example, about 10 mm to 30 mm, or about 20 mm to 30 mm. As shown in Figure 2, the thickness dimension of the trim frame 20 is approximately the same as the thickness dimension (visible dimension) of the door-end vertical frame 7b. The width dimension of the trim frame 20 along the wall thickness direction may be an appropriate dimension from the perspective of ensuring the fixing strength of the end-side vertical frame 7b to which it is fixed, from the perspective of appearance, etc. The end-side vertical frame 7b (door frame 7) is fixed to the trim frame 20 so that its center in the projection direction coincides with the center of the trim frame 20 in the projection direction. The surfaces of the end-side vertical frame 7b facing the trim frame 20 at both ends in the projection direction, as well as the projection surfaces and projection surfaces on both sides, may be decorative surfaces formed by applying veneer or decorative film, or by painting. Furthermore, the surface of the end-side vertical frame 7b facing the trim frame 20 may have a non-decorative surface between the decorative surfaces at both ends in the projection direction. In this case, the width dimension of the trim frame 20 may be equal to or greater than the width dimension along the wall thickness direction of the non-decorative surface of the end-side vertical frame 7b facing the trim frame 20.

[0017] The width of the trim frame 20 may be equal to or greater than the wall thickness of the wall constituting the second wall portion 6, and equal to or less than the width (projected dimension) along the wall thickness direction of the leading-side vertical frame 7b. The width of the trim frame 20 is not limited, but may be, for example, approximately 80 mm to 180 mm. The illustrated example shows an example in which the width of the trim frame 20 is greater than the wall thickness of the wall constituting the second wall portion 6, and slightly smaller than the width of the leading-side vertical frame 7b. Alternatively, the width of the trim frame 20 may be approximately the same as the width of the leading-side vertical frame 7b. This trim frame 20 may be fixed to the partition panel 10 at multiple locations along the vertical direction by fasteners 9 attached from the vertical frame 15 side. The trim frame 20 may be fixed to the ceiling 3 side by fasteners that fasten its upper end diagonally to a fixing target on the ceiling 3 side. The trim frame 20 may be fixed to the floor 4 side by fasteners 9 that fasten its lower end diagonally to a fixing target on the floor 4 side, such as a floor subfloor or floor material (see Figure 5). The door-end vertical frame 7b fixed to this trim frame 20 may be fixed by fasteners that fasten to the door-end vertical frame 7b via one or both of the end ends of the trim frame 20 in the projection direction, instead of, or in addition to, the fasteners 9 that are fastened via the bottom of the mounting groove as described above.

[0018] At least the exposed surfaces of the trim frame 20 and the vertical frames 15 may be decorative surfaces of the same color and pattern. With this configuration, the trim frame 20 and the vertical frames 15 of the partition panel 10 appear to be integrated, improving the appearance. Here, the term "same color and pattern" does not necessarily mean "same color and pattern" but may also mean that the color difference between the two is so small that they are difficult to visually distinguish, as long as they are each a single color, and may also include those in which a similar pattern or design is applied in a similar color. Instead of this configuration, the decorative surface of the trim frame 20 may be the same color and pattern as the decorative surface of the door frame 7. The decorative surface of this trim frame 20 may be formed on at least the surface that is exposed when installed. This trim frame 20 may be configured such that a surface material, the surface of which is made into a decorative surface by adhering a decorative sheet such as veneer or resin film, or by painting, is wrapped around and attached to the surface of a core material made of a wood-based material such as plywood. Such a surface material may be configured such that a decorative layer that forms the decorative surface is provided on the front side of a surface base material made of a wood-based board such as MDF (medium density fiberboard), and folding grooves that correspond to the corners of the core material are provided on the back side.

[0019] The multiple partition panels 10, 10 include a first panel 10A on the side of the trim frame 20 and a second panel 10B on the side of the first wall portion 5. As shown in Figure 2, the first panel 10A and the second panel 10B are installed so that their centers in the wall thickness direction coincide with the center in the same direction of the trim frame 20. Since the first panel 10A and the second panel 10B have the same configuration, in the following, when it is not necessary to distinguish between them, one of them will be taken as an example and described as the partition panel 10. As shown in Figure 1, the perimeter frame 12 of the partition panel 10 includes an upper frame 13 fixed to the ceiling 3, a lower frame 14 fixed to the floor 4, and vertical frames 15, 15 on both sides of the wall width direction. The partition panel 10 includes horizontal frames 16 attached to the perimeter frame 12 so as to divide the interior space into upper and lower sections. In the illustrated example, the partition panel 10 includes multiple horizontal frames 16 (four in the illustrated example). Also shown is an example in which multiple plate-like members 11 (five in the illustrated example) are provided in each of the openings divided into upper and lower sections by these horizontal frames 16.

[0020] The plate-shaped member 11 is formed of a translucent material such as a synthetic resin material such as acrylic or polycarbonate or glass, and is a translucent plate having translucency. In other words, the plate-shaped member 11 constitutes a lighting section. The plate-shaped member 11 may be, for example, laminated glass formed by joining two glass plates together in the thickness direction. The plate-shaped member 11 is not limited to being substantially colorless and transparent, but may also be colored and transparent or translucent. The plate-shaped member 11 may be, for example, a transparent material to which a colorant is added, or may be a transparent material to which a resin film or the like is laminated. The plate-shaped member 11 may be smoked glass or frosted glass, or may be a decorative translucent plate with various patterns such as checkered, moire, aqua, rain, or mist. It may also have various other configurations. The plate-shaped member 11 may be formed by sandwiching a sheet material such as Japanese paper between two transparent (translucent) panels.

[0021] The plate-like members 11 may be half-mirror-shaped, or may have mirrors on both sides in the thickness direction, or may be other opaque plates. Furthermore, both sides in the thickness direction are not limited to being substantially flat, and may have irregularities. While the illustrated example shows five plate-like members 11 with substantially the same vertical dimension, this is not a limitation. While the illustrated example shows each of the plate-like members 11 fixedly attached to each opening, i.e., as a fixed window, at least one of the plate-like members 11 may instead constitute a movable window. While the illustrated example shows a thin plate-like member 11 attached to each opening, a panel having a thickness substantially equal to the wall thickness of the four-periphery frame 12 may be attached to any of the openings.

[0022] As shown in Figures 2 and 3(a), the inner peripheral surface of the four-periphery frame 12 is provided with receiving grooves 13a, 14a, 15a, and 15a that receive the peripheral end 11a of the plate-like member 11. Gaskets (glazing gaskets) 17, 17, 17, and 17 that hold the peripheral end 11a of the plate-like member 11 are fitted into the receiving grooves 13a, 14a, 15a, and 15a. Such gaskets 17 may be so-called glazing channels with a roughly C-shaped cross section or glazing beads separated in the wall thickness direction (thickness direction of the plate-like member 11). Although not shown, similar receiving grooves into which gaskets 17 are fitted are also provided on the upper and lower surfaces of the horizontal frame 16.

[0023] As shown in Figure 3(a), the upper frame 13 is fixed to a fixing target on the ceiling 3 side by fasteners 9. This upper frame 13 is elongated in the wall width direction and is roughly rectangular when viewed in the longitudinal direction. The vertical dimension of this upper frame 13 and the projected dimension in the wall thickness direction may be set as appropriate from the standpoints of appearance and strength, stable holding of the plate-like member 11, fixability of the partition panel 10, etc. In the example shown, the projected dimension of the upper frame 13 is larger than its projected dimension. The receiving groove 13a of the upper frame 13 is provided so as to open downward on the lower surface that constitutes the inner peripheral surface of the four-periphery frame 12. The receiving groove 13a is provided over the entire length of the upper frame 13. The receiving groove 13a is provided in approximately the center of the upper frame 13 in the projection direction. In the illustrated example, an example is shown in which retaining pieces that protrude in opposing directions and prevent the gasket 17 from coming off are provided at the opening side portions of the groove wall surfaces on both sides that define both sides in the groove width direction of the receiving groove 13a.

[0024] Hollow portions are provided so as to penetrate the entire length of the receiving groove 13a of the upper frame 13 on both sides in the projection direction. In other words, both sides of the receiving groove 13a of the upper frame 13 in the projection direction are hollow cylindrical. The upper frame 13 is provided with a head insertion hole 13b through which the head of the fastener 9 is inserted. The head insertion hole 13b is provided to penetrate a lower wall portion that defines the lower side of the hollow portion on one side of the upper frame 13 in the projection direction. The inner diameter of the head insertion hole 13b is larger than the outer diameter of the head so that the head of the fastener 9 can be inserted therethrough. A cap member 18 may be provided to cover the head insertion hole 13b (see the two-dot chain line). An insertion hole through which the shank of the fastener 9 is inserted may also be provided in the upper wall portion that defines the upper side of the hollow portion on one side of the upper frame 13 in the projection direction. The illustrated example shows an example in which a recessed groove that opens upward on the top surface is provided along the entire length, approximately in the center of the upper frame 13 in the projection direction.

[0025] The lower frame 14 is fixed to a fixing target on the floor 4 side by fasteners 9. The lower frame 14 is elongated in the wall width direction and has a generally rectangular shape when viewed in the longitudinal direction. The lower frame 14 has the same size and shape as the upper frame 13, i.e., they are made of the same material. The lower frame 14 is provided with receiving grooves 14a similar to those described above and head insertion holes 14b through which the heads of the fasteners 9 are inserted. As described above, the receiving grooves 14a are provided on the upper surface constituting the inner peripheral surface of the four-periphery frame 12 so as to open upward and extend over the entire length of the lower frame 14. As described above, the head insertion holes 14b are provided so as to penetrate the upper wall portion that defines the upper side of the hollow portion on one side of the lower frame 14 in the projection direction. A cap member 18 may be provided to cover the head insertion holes 14b. A through-hole through which the shaft of the fastener 9 is inserted may also be provided in a lower wall defining the lower side of the hollow portion on one side of the lower frame 14 in the projection direction. As described above, a recess 14c that opens downward is provided on the lower surface over the entire length at approximately the center of the lower frame 14 in the projection direction.

[0026] The horizontal frame 16 is elongated in the wall width direction and has a generally rectangular shape when viewed in the longitudinal direction. The projection dimensions and the projected dimensions of the horizontal frame 16 may be appropriately determined from the viewpoints of appearance, strength, and stable support of the plate-like member 11. The projection dimensions and the projected dimensions of the horizontal frame 16 may be approximately the same as those of the upper frame 13 and the lower frame 14. The horizontal frame 16 has receiving grooves similar to those described above that run along its entire length and open on both sides in the vertical direction. These receiving grooves are located approximately in the center of the horizontal frame 16 in the projected direction, as described above. The opening-side portions of the groove wall surfaces on both sides that define the groove width direction of these receiving grooves are provided with anti-detachment pieces, as described above. Instead of a configuration in which such a horizontal frame 16 is provided, a horizontal bar-like member may be provided that is attached to one or both sides in the thickness direction of a plate-like member 11 that is provided in a single piece within the four-perimeter frame 12, or further, a configuration in which such a horizontal frame 16 or horizontal bar-like member is not provided may be used.

[0027] As shown in Figures 1 and 2, the vertical frames 15, 15 on both sides of the wall width direction are elongated in the vertical direction and generally rectangular in shape when viewed longitudinally. These vertical frames 15, 15 are the same size and shape, i.e., made of the same material. These vertical frames 15, 15 are hollow tubular with a hollow portion extending longitudinally. The projection dimensions along the wall width direction and the projection dimensions along the wall thickness direction of these vertical frames 15, 15 may be appropriately set based on factors such as appearance, strength, and the ability to stably support the plate-like member 11, as described above. In the illustrated example, the projection dimensions and projection dimensions of these vertical frames 15, 15 on both sides are approximately the same as those of the upper frame 13 and the lower frame 14. The receiving grooves 15a, 15a of the vertical frames 15, 15 on both sides are provided, similarly to the above, over their entire lengths so as to open toward the center in the panel width direction, which is the opposing direction, on the opposing side surfaces that constitute the inner peripheral surface of the four-perimeter frame 12. As described above, these receiving grooves 15a, 15a are provided in approximately the center in the projection direction of each vertical frame 15, 15. As described above, anti-detachment pieces are provided at the opening sides of the groove wall surfaces on both sides that define both sides in the groove width direction of these receiving grooves 15a, 15a.

[0028] The head insertion holes 15b of these vertical frames 15 are provided to penetrate the inner peripheral wall portions that constitute the opposing side surfaces. The head insertion hole 15b of one vertical frame 15 and the head insertion hole 15b of the other vertical frame 15 are provided on different sides in the projection direction. That is, the head insertion hole 15b of one vertical frame 15 is provided on one side of the plate-like member 11 in the projection direction, and the head insertion hole 15b of the other vertical frame 15 is provided on the other side of the plate-like member 11 in the projection direction. As described above, the inner diameter of these head insertion holes 15b is larger than the outer diameter of the head portion so that the head of the fastener 9 can be inserted therethrough. Cap members 18 are provided to cover the head insertion holes 15b. An insertion hole through which the shaft portion of the fastener 9 is inserted may be provided so as to penetrate the outer wall portion that forms the opposite surface of the vertical frames 15, 15 and to be coaxial with the head insertion holes 15b, 15b.

[0029] The vertical frames 15, 15 of adjacent partition panels 10, 10 may be joined by fastening a fastener 9 inserted through the head insertion hole 15b of one of the vertical frames 15, 15 to the vertical frame 15 on the other side. The fastening portion of the other vertical frame 15 may be provided with an appropriate nut member, a female screw hole, a pilot hole, or the like. The illustrated example shows an example in which the fastener 9 inserted through the head insertion hole 15b on one side of the vertical frame 15 on the joining side of the first panel 10A in the projection direction is fastened to a fastening portion on one side of the vertical frame 15 on the joining side of the second panel 10B in the projection direction. Also shown is an example in which the fastener 9 inserted through the head insertion hole 15b on the other side of the vertical frame 15 on the joining side of the second panel 10B in the projection direction is fastened to a fastening portion on the other side of the vertical frame 15 on the joining side of the first panel 10A in the projection direction. Also, an example is shown in which the fastener 9 is inserted through the head insertion hole 15b on the other side of the vertical frame 15 on the trim frame 20 side of the first panel 10A in the projection direction and fastened to the trim frame 20.

[0030] The faces of these vertical frames 15, 15 facing outward in the panel width direction are provided with seal receiving grooves 15c, 15c that can accommodate sealant (packing) 19, and these grooves open toward the outside in the panel width direction and run along their entire lengths. The illustrated example shows an example in which the seal receiving grooves 15c, 15c are provided on both sides of the faces of the vertical frames 15, 15 facing outward in the panel width direction. The illustrated example shows an example in which sealants 19, 19 that elastically deform and contact the abutting object are provided in the seal receiving grooves 15c, 15c of the vertical frame 15 on the first wall portion 5 side of the second panel 10B that abuts against the first wall portion 5. The illustrated example also shows an example in which the seal receiving groove 15c on one side of the vertical frame 15 on the parting frame 20 side of the first panel 10A that abuts against the parting frame 20, in the projection direction, is provided with sealant 19 that elastically deforms and contacts the abutting object.

[0031] These vertical frames 15, 15 are joined to the upper frame 13 and the lower frame 14 in a so-called vertical joint configuration. That is, these vertical frames 15, 15 are joined to the upper frame 13 and the lower frame 14 by butting the longitudinal end faces of the upper frame 13 and the lower frame 14 against the opposing side faces at the top and bottom ends of the vertical frames 15, 15. The horizontal frame 16 is joined to each vertical frame 15, 15 by butting the longitudinal end faces of the horizontal frame 16 against the opposing side faces at the vertical midpoint of the vertical frames 15, 15. The vertical frames 15, 15 may be joined to the upper frame 13, the lower frame 14, and the horizontal frame 16 by fasteners attached from the outer sides of the vertical frames 15, 15 in the panel width direction to fastening portions provided on the upper frame 13, the lower frame 14, and the horizontal frame 16. In this case, insertion holes through which the fasteners are inserted may be provided in appropriate positions on the vertical frames 15, 15. The joining of the vertical frames 15, 15 to the upper frame 13, the lower frame 14, and the horizontal frame 16 is not limited to this mode, and they may be joined via appropriate metal fittings or in various other modes.

[0032] The upper frame 13, lower frame 14, vertical frames 15, 15, and horizontal frames 16 that make up the four-perimeter frame 12 may be extrusion molded products made of metal or synthetic resin material with a substantially uniform cross-sectional shape along their entire length. Examples of metal materials include aluminum and stainless steel. Examples of synthetic resin materials include polyvinyl chloride resin and various other resins, and may also include so-called fiber-reinforced resins containing reinforcing fibers such as glass fiber and carbon fiber. The surfaces of the upper frame 13, the lower frame 14, the vertical frames 15, 15, and the horizontal frames 16 may be decorative surfaces that have been appropriately treated with a coating, a decorative sheet, etc. For example, the surfaces of the upper frame 13, the lower frame 14, the vertical frames 15, 15, and the horizontal frames 16 may be finished in an iron-like black or matte white.

[0033] As shown in FIG. 3, the partition wall device 1 includes a ceiling-side base 21 that is fixed along the ceiling 3 side and has a mating portion 21c that fits into a mating portion 13c, which is made up of one of a recess and a protrusion, provided on the upper frame 13 of the partition panel 10. The partition wall device 1 includes a floor-side base 22 that is fixed along the floor 4 side and has a protrusion that fits into a recess 14c provided on the lower frame 14 of the partition panel 10. The partition panel 10 is installed in a staggered manner by fitting the mating portion 13c of the upper frame 13 into the mating portion 21c of the ceiling-side base 21, and then fitting the protrusion of the floor-side base 22 into the recess 14c of the lower frame 14. With this configuration, the partition panel 10 can be temporarily held by the ceiling-side base 21 and the floor-side base 22, making it easy to install the partition panel 10.

[0034] The ceiling-side base 21 is elongated in the wall width direction. The fitting portion 21c of the ceiling-side base 21 is a recess that receives the upper portion of the upper frame 13 itself, which serves as the fitting portion 13c of the upper frame 13 that constitutes the upper end of the partition panel 10. The fitting portion 21c of the ceiling-side base 21 is defined by a fixing piece 21a arranged along the ceiling 3 and holding pieces 21b, 21b that hang down from both ends of the fixing piece 21a in the wall thickness direction, and is a groove-like portion that opens downward. The fitting portion 13c of the upper end (upper frame 13) of the partition panel 10 is inserted between these holding pieces 21b, 21b and temporarily held. The ceiling-side base 21 may be fixed to a fixed object by a fastener 9 that penetrates the fixing piece 21a and is fastened to the fixed object. The ceiling-side base 21 may be provided with an insertion hole through which the fastener 9 is inserted. The length of the ceiling-side base 21 may be set to a dimension corresponding to the sum of the widths of the multiple partition panels 10, 10. The depth of the fitted portion 21c in the vertical direction may be set to an appropriate dimension so that the protrusion of the floor-side base 22 can be inserted into the recess 14c of the lower frame 14 of the partition panel 10 when the fitting portion 13c of the partition panel 10 is received in the fitted portion 21c.

[0035] The floor-side base 22 is elongated in the wall width direction and forms a protrusion to be inserted into the recess 14c provided in the lower end (lower frame 14) of the partition panel 10. The floor-side base 22 is in the shape of a strip arranged along the floor 4 so that its thickness direction is the up-down direction. The floor-side base 22 may be fixed to a fixed object by a fastener 9 that penetrates the floor-side base 22 and is fastened to the fixed object. The floor-side base 22 may be provided with an insertion hole through which the fastener 9 is inserted. The length of the floor-side base 22 may be smaller than the groove length of the recess 14c of each partition panel 10. The length of the floor-side base 22 may be set appropriately taking into account the finger insertion space required between the partition panel 10 and an adjacent object when installed in a staggered manner. The length dimension of this floor side base 22 may be set to a dimension corresponding to the sum of the width dimensions of multiple partition panels 10, 10 if a recess is also provided at the lower end of the above-mentioned vertical frame 15. The groove width and depth of the recess 14c are set to appropriate dimensions so that the floor-side base 22 can be received. The ceiling-side base 21 and the floor-side base 22 may be formed from an appropriate metal material or synthetic resin material. The surface of the ceiling-side base 21 may be a decorative surface that has been treated with a surface finish of the same color and pattern as the four-perimeter frame 12 (upper frame 13). The shapes of the ceiling-side base 21 and the floor-side base 22 are not limited to those shown in the illustrations and can be modified as appropriate.

[0036] The partition wall construction method according to this embodiment includes a panel installation step of fixing the lower end of the partition panel 10 to the floor 4 and the upper end of the partition panel 10 to the ceiling 3, and then installing the partition panel 10. Prior to this panel installation step, as shown in FIG. 4(a), the above-mentioned ceiling-side base 21 may be fixed to the ceiling 3, and the floor-side base 22 may be fixed to the floor 4. Then, for example, the second panel 10B on the first wall portion 5 side may be temporarily held to the ceiling-side base 21 and the floor-side base 22, and then the first panel 10A on the second wall portion 6 side may be temporarily held to the ceiling-side base 21 and the floor-side base 22 (see FIG. 3(b)). Then, the upper frames 13, 13 of the first panel 10A and the second panel 10B may be fixed to the ceiling 3 side with fasteners 9, and the lower frames 14, 14 of the first panel 10A and the second panel 10B may be fixed to the floor 4 side with fasteners 9 (see FIG. 3(a)). Furthermore, the vertical frame 15 of the first panel 10A on the second panel 10B side and the vertical frame 15 of the second panel 10B on the first panel 10A side may be joined together with fasteners 9 (see FIG. 5).

[0037] As shown in Fig. 5, the partition wall construction method includes a trim installation step of fixing the trim frame 20 along the vertical frame 15 of the partition panel 10 on the trim frame 20 side with fasteners 9. In this trim installation step, the trim frame 20 may be fixed to the partition panel 10 by fastening the fasteners 9 to the trim frame 20 from the vertical frame 15 side through the head insertion holes 15b of the vertical frame 15. The upper and lower ends of the trim frame 20 may also be fixed to fixing targets on the ceiling 3 and floor 4 sides with the fasteners 9. In this state, as shown in Fig. 6(a), a door frame installation opening is formed whose upper side is defined by the ceiling 3 and whose lower side is defined by the floor 4, and whose both sides in the opening width direction are defined by the second wall portion 6 and the trim frame 20. As shown in Figure 6(b), this partition wall construction method includes a door frame installation step of aligning and fixing the door-end vertical frame 7b of the door frame 7 to which the door body 8 is to be erected, along the side of the trim frame 20 opposite the partition panel 10 in the wall width direction. In this door frame installation step, the door frame 7 may be installed in the door frame installation opening in a state in which the door-end vertical frame 7b and the hanging-end vertical frame 7c are joined to both ends of the top frame 7a to form a three-sided frame. Then, as shown in Figure 1, the door body 8 may be erected into the door frame 7. The construction procedure for the partition wall device 1 is not limited to the above-described configuration, and various other configurations can be adopted.

[0038] Next, a modified example of the partition wall device 1, an article named "building partition," will be described with reference to the exterior design drawings of Figures 7 to 9. Although reference numerals are omitted in Figures 7 to 9, in the following description, the same components as those described above and components corresponding to those described above will be assigned the same numerals as those in Figures 1 to 6. In Figures 7(a) to (c), Figures 8(a) to (c), and Figure 9(a), solid lines indicate the outer contours of the door frame 7 and the door body 8, as well as the portions other than the uppermost light-transmitting portion (plate-like member 11) of the partition panel 10 (first panel 10A) on the door frame 7 side. Also, in Figures 7(a) to (c), Figures 8(a) to (c), and Figure 9(a), dashed lines indicate the boundaries between the four stiles of the door body 8 and the plate-like members, the handles, the hinges, the uppermost light-transmitting portion (plate-like member 11) of the partition panel 10 (first panel 10A) on the door frame 7 side, and the partition panel 10 (second panel 10B) on the first wall portion 5 side. Note that any portion of the solid lines may be dashed, or any or all of the dashed line portions may be solid. In FIG. 9(b), the light-transmitting portions (transparent portions) are indicated by hatching.

[0039] In this modified example, the door body 8 is also shown as having a translucent plate-like member provided within the four stiles, but it is not limited to this example and may be made of any design or material. Similarly, the handle of the door body 8 is not limited to a lever-like configuration and may be a knob-like, push-pull handle, or any other configuration. Furthermore, the hinge that connects the door body 8 to the hanging side vertical frame 7c is not limited to a blade-like configuration as shown in the illustration, and may be a hidden hinge, slide hinge, or any other configuration. In this modified example, the uppermost light-transmitting portion (plate-shaped member 11) of the partition panel 10 is a movable window. In the illustrated example, the movable window is a protruding window whose upper end is connected to be rotatable around an axis along the panel width direction and whose lower end is provided with an operating unit, but the movable window is not limited to this example. In addition, in this modified example, the partition panel 10 is an example in which a single opaque panel body (one tier) is incorporated instead of the bottom two tiers of translucent portions (plate-like members 11) in the example described above.

[0040] In each of the above examples, a ceiling-side base 21 that holds the upper end of the partition panel 10 and a floor-side base 22 that holds the lower end of the partition panel 10 are provided, but the configuration may also be such that one or both of these are not provided. In each of the above examples, the door-end side vertical frame 7b of the door frame 7 is fixed to the trim frame 20, but the hanging side vertical frame 7c may also be fixed to the trim frame 20. Furthermore, the door frame 7 is not limited to an example in which the door body 8 that constitutes a hinged door is attached, and may be a door frame 7 for a folding door, a sliding door, or the like. In the above examples, a partition wall device 1 having a plurality of partition panels 10, 10 is illustrated, but the partition wall device 1 may also have only one partition panel 10. The configurations of the components and parts of the partition wall device 1 according to this embodiment are not limited to those described above, and various other modifications are possible.
