[0001] The present invention relates to a partition panel installation method and a partition panel. [Background technology]

[0002] BACKGROUND ART Partition walls that are installed to separate spaces within a building have been known for some time. In some cases, such partition walls are provided with a light-transmitting portion in part for the purpose of admitting light. For example, Patent Document 1 below discloses a partition member that includes a support member with a groove formed along the longitudinal direction, and first and second frame members that are fitted into the groove of the support member and hold a partition member such as glass. The support members of this partition member are used as ceiling frame members that are attached to the ceiling side, floor frame members that are attached to the floor side, and studs that are attached at predetermined intervals between them.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-336340 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the partition member described in Patent Document 1 requires that thin glass plates, which are difficult to handle, be installed at the construction site, and if it is desired to partially install panel bodies such as decorative panels in place of glass, this is difficult to achieve because the thickness dimensions vary.

[0005] The present invention has been made in consideration of the above-mentioned situation, and aims to provide a partition panel installation method and a partition panel that can partially attach panel bodies of different thicknesses from translucent panels while improving ease of handling. [Means for solving the problem]

[0007] In order to achieve the above object, the partition panel according to the present invention comprises a four-sided frame having an upper frame fixed to a fixed object on the ceiling side by fasteners, vertical frames on both sides in the wall width direction, and a lower frame fixed to a fixed object on the floor side by fasteners, horizontal frames attached so as to divide the inside of the four-sided frames into upper and lower sections, a light-transmitting plate attached to one of the openings divided into upper and lower sections by the horizontal frames, and a fixed object-side frame and the horizontal frame that are thicker than the light-transmitting plate and constitute at least one of the upper frame and the lower frame. The vertical frames on both sides and a panel body that is fitted into and attached to the attachment opening defined by the fastener so as to cover the portion of the attachment target frame through which the fastener passes. [Effects of the Invention]

[0008] The partition panel installation method and partition panel of the present invention are configured as described above, which improves ease of handling while allowing panel bodies of different thicknesses to be partially attached to the translucent plate. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the 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 a state in which an example of a partition panel according to this embodiment is installed. 1 to 5 are diagrams that schematically show an example of a partition panel according to this embodiment, an example of a partition wall device including the same, and an example of a method for installing the partition panel according to this embodiment.

[0011] The method for constructing a partition panel according to this embodiment is a method for constructing the partition panel 10 according to this embodiment as an example of a partition panel. As shown in Fig. 1, the partition panel 10 according to this embodiment is provided with a four-perimeter frame (four-perimeter frame) 12, which includes an upper frame 13 fixed to the ceiling 2, vertical frames 15, 15 on both sides in the wall width direction, and a lower frame 14 fixed to the floor 3. This partition panel 10 may be combined with other partition panels 10 to form a partition wall device 1. Fig. 1 illustrates a partition wall device 1 that includes a plurality of partition panels 10, 10 (two in the illustrated example), a door frame 7, and a door panel 8 attached to the door frame 7. In the illustrated example, a hinged door is shown as the door panel 8, but the present invention is not limited to this example. This partition wall device 1 is installed to divide the interior of a building.

[0012] The door frame 7 includes an upper frame 7a that is fixed to an upper frame base such as a ceiling base that is fixed to the ceiling 2 side so as to fit along the ceiling 2, a door-end vertical frame 7b, and a hanging-side vertical frame 7c that holds the door panel 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 panel 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. The hanging-side vertical frame 7c may be fixed to a vertical frame base such as a wall base. The illustrated example shows an example in which the door-end vertical frame 7b is arranged along a vertical frame member 6 that is fixed to the vertical frame 15 of the adjacent partition panel 10, and is fixed to this vertical frame member 6. The upper and lower ends of this vertical frame member 6 may be fixed to a ceiling base, floor base, floor material, etc. that are fixed to the ceiling 2 side and floor 3 side. In the illustrated example, the dimension of this vertical frame member 6 along the wall width direction is approximately the same as the dimension of the door-end vertical frame 7b along the same direction, but this is not limited to this example.

[0013] As shown in FIG. 2, the partition wall device 1 includes an upper guide 4 and a lower guide 5 that temporarily hold the upper and lower end sides of the partition panel 10. The upper guide 4 is provided to extend in the panel width (wall width) direction and is shaped to define a recess that receives the upper end of the partition panel 10. The upper guide 4 includes a fixing piece portion disposed along the ceiling 2 and a holding piece portion provided to hang down from both ends of the fixing piece portion in the panel thickness (wall thickness) direction. The upper end (upper frame 13) of the partition panel 10 is inserted between these holding pieces and temporarily held. The upper guide 4 may be fixed to a fixed object by a fastener 9 that penetrates the fixing piece portion and is fastened to the fixed object. The upper guide 4 may be provided with an insertion hole through which the fastener 9 is inserted. The length of the upper guide 4 may be set to a dimension corresponding to the sum of the panel width dimensions of the plurality of partition panels 10, 10.

[0014] The lower guide 5 is provided to extend in the wall width direction and constitutes a protrusion to be inserted into a retaining groove 14c provided in the lower end (lower frame 14) of the partition panel 10. The lower guide 5 is in the shape of a strip arranged along the floor 3 so that its thickness direction is the up-down direction. The lower guide 5 may be fixed to a fixed object by a fastener 9 that penetrates the lower guide 5 and is fastened to the fixed object. The lower guide 5 may be provided with an insertion hole through which the fastener 9 is inserted. The length of the lower guide 5 may be smaller than the length of the retaining groove 14c of each partition panel 10. When a retaining groove is also provided in the vertical frame 15 as described below, the length of the lower guide 5 may be set to a dimension corresponding to the sum of the panel widths of the multiple partition panels 10, 10.

[0015] These upper guides 4 and lower guides 5 are provided so that the upper end of the partition panel 10 can be received in the recess of the upper guide 4, and the lower guide 5 can be received in the holding groove 14c of the lower end of the partition panel 10, allowing the partition panel 10 to be erected in a buckling manner. With this configuration, the upper frame 13 and the lower frame 14 can be fixed to their respective fixing targets using fasteners 9, 9, with the partition panel 10 temporarily held in the upper guide 4 and lower guide 5. These upper guides 4 and lower guides 5 may be made of an appropriate metal material or synthetic resin material. The shapes of these upper guides 4 and lower guides 5 are not limited to those shown in the drawings and can be modified as appropriate.

[0016] In a plurality of adjacent partition panels 10, 10 (two in the illustrated example), adjacent vertical frames 15, 15 may be connected to each other with fasteners such as screws or other suitable connecting members. Of these plurality of partition panels 10, 10, the partition panel 10 installed at the end on the side opposite the door frame 7 may have the vertical frame 15 on that end side aligned with the adjacent partition wall, etc. Since these plurality of partition panels 10, 10 have the same configuration, the following description will be given taking one panel as an example. As shown in Figure 1, the partition panel 10 comprises a panel body 11 having horizontal frames 16 attached to the four-way frame 12 to divide the interior space into upper and lower sections, and a light-transmitting plate 18 attached to one of the openings divided into upper and lower sections by the horizontal frames 16. With this configuration, a daylighting section can be formed by the light-transmitting plate 18, and the partition panel 10 can be installed as a daylighting panel.

[0017] The partition panel 10 includes a panel body 20 that is thicker than the light-transmitting plate 18 and is fitted into an attachment opening 19 defined by the horizontal frame 16 and the fixation target frame that constitutes at least one of the upper frame 13 and the lower frame 14. In other words, the partition panel 10 is configured such that the light-transmitting plate 18 and the panel body 20, which is thicker than the light-transmitting plate 18, are arranged above and below the horizontal frame 16 within the four-perimeter frame 12. This configuration allows the panel body 20 to be provided in a transom-like configuration on the ceiling 2 side or in a wainscot-like configuration on the floor 3 side. The panel body 20 is fitted into the fixation target frame so as to cover the penetration portion of the fastener 9. This configuration allows the thicker panel body 20 to be attached to the panel main body 11 after the fact, and thereby allows the fixation target frame to be stably fixed to the fixation target by the fastener 9. Furthermore, the portion of the fixing target frame through which the fastener 9 passes can be made less noticeable.

[0018] Specifically, the partition panel 10 includes a plurality of horizontal frames 16 (three in the illustrated example), a plurality of light-transmitting plates 18 (three in the illustrated example), and one panel body 20. That is, the panel body 11 is configured such that the light-transmitting plates 18 are attached to three of four openings defined vertically by the three horizontal frames 16. The mounting opening 19 of the panel body 11 is defined vertically by the lower frame 14 serving as a fixing target frame and the horizontal frame 16 above it. That is, the partition panel 10 is configured such that the light-transmitting plates 18 are attached to each of the three upper openings, and the panel body 20 is attached to the lower mounting opening 19 like a wainscot. While the illustrated example shows an example in which the three light-transmitting plates 18 are all substantially the same in the vertical direction, this is not limiting. Furthermore, although an example has been shown in which each of these light-transmitting plates 18, 18, 18 is fixedly provided in each opening, i.e., in the form of a fixed window (FIX window), instead of such an example, at least one of the plates may constitute a movable window.

[0019] The light-transmitting plate 18 is formed from a synthetic resin material such as acrylic or polycarbonate, or a light-transmitting material such as glass. The light-transmitting plate 18 may be, for example, laminated glass formed by bonding two glass plates together in the thickness direction. The light-transmitting plate 18 is not limited to being substantially colorless and transparent, but may also be colored and transparent or translucent. The light-transmitting plate 18 may be, for example, a transparent material to which a colorant has been added, or may be a transparent material to which a resin film or the like has been laminated. The light-transmitting plate 18 may have a smoked glass or frosted glass finish, or may be a decorative light-transmitting plate with various patterns such as checkered, moire, aqua, rain, or mist. It may also have various other configurations. The light-transmitting plate 18 may be formed by sandwiching a sheet material such as Japanese paper between two transparent (light-transmitting) panels.

[0020] 2 and 3(a), receiving grooves 13a, 14a, 15a, and 16a are provided on the inner peripheral surface of the four-periphery frame 12 and the upper and lower surfaces of the horizontal frame 16 to receive the peripheral end 18a of the light-transmitting plate 18. Gaskets (glazing gaskets) 17, 17, 17, and 17 that hold the peripheral end 18a of the light-transmitting plate 18 are fitted into the receiving grooves 13a, 14a, 15a, and 16a at locations where the peripheral end 18a of the light-transmitting plate 18 is received. Such gaskets 17 may be so-called glazing channels with a substantially C-shaped cross section or glazing beads separated in the wall thickness direction (thickness direction of the light-transmitting plate 18).

[0021] As shown in Figure 2, the upper frame 13 is fixed to a fixing target on the ceiling 2 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 translucent panel 18, and fixation of the partition panel 10. In the example shown, the projected dimension of the upper frame 13 is larger than its vertical 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.

[0022] 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 an insertion hole 13b through which the fastener 9 is inserted and which constitutes the penetration portion of the fastener 9. The 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 insertion hole 13b is larger than the outer diameter of the head of the fastener 9 so that the head of the fastener 9 can be inserted therethrough. A cap member may be provided to cover the insertion hole 13b (see the two-dot chain line). An insertion hole through which the shaft 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.

[0023] The lower frame 14 is fixed to a fixing target on the floor 3 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 insertion holes 14b that form the penetration portions of the fasteners 9. As described above, the receiving grooves 14a are provided in the upper surface that forms 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 insertion holes 14b are provided so as to penetrate an upper wall that defines the upper side of the hollow portion on one side of the lower frame 14 in the projection direction. An insertion hole through which the shaft of the fastener 9 is inserted may also be provided in the lower wall that defines the lower side of the hollow portion on one side of the lower frame 14 in the projection direction. As described above, a holding groove 14c that opens downward is provided along the entire length of the lower surface of the lower frame 14 in the approximate center in the projection direction of the lower frame 14. The groove width and groove depth of this holding groove 14c are set to appropriate dimensions so that the above-mentioned lower guide 5 can be received.

[0024] The horizontal frame 16 is elongated in the width direction of the wall and has a roughly rectangular shape when viewed in the longitudinal direction. The projection dimensions and the planar dimensions of the horizontal frame 16 may be set as appropriate from the standpoints of appearance, strength, and stable support of the light-transmitting plate 18. In the illustrated example, the projection dimensions and the planar dimensions of the horizontal frame 16 are approximately the same as those of the upper frame 13 and the lower frame 14. Receiving grooves 16a, 16a similar to those described above are provided along the entire length of the horizontal frame 16 so as to be open on both the top and bottom sides. As described above, these receiving grooves 16a, 16a are provided in the approximate center in the projection direction of the horizontal frame 16. As described above, anti-detachment pieces 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 these receiving grooves 16a, 16a. The horizontal frame 16 has a wall portion that connects the parts that make up the groove bottoms of these receiving grooves 16a, 16a, and is configured with hollow portions that run through the entire length of this wall portion on both sides of the projection direction.

[0025] As shown in Figures 1 and 3(a), 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 identical in size and shape, i.e., made of the same material. These vertical frames 15, 15 are hollow cylindrical with a hollow portion extending longitudinally. The projected dimensions of these vertical frames 15, 15 along the wall width direction and along the wall thickness direction may be appropriately adjusted based on factors such as appearance, strength, and the ability to stably support the translucent panel 18, as described above. In the illustrated example, the projected dimensions of these vertical frames 15, 15 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.

[0026] On the surfaces of both vertical frames 15, 15 facing outward in the panel width direction, seal receiving grooves capable of accommodating sealant (packing) are provided over the entire length of the frames, opening toward the outside in the panel width direction. The illustrated example shows an example in which seal receiving grooves are provided on both sides of the surfaces of the vertical frames 15, 15 facing outward in the panel width direction in the projection direction. For example, a sealant that elastically deforms and comes into contact with the object of abutment may be provided in the seal receiving groove of the vertical frame 15 that abuts against an adjacent partition wall or the like. These vertical frames 15, 15 may be provided with insertion holes through which fasteners for connecting the vertical frames 15, 15 of adjacent partition panels 10 are inserted. A holding groove may be provided at the lower end of each of these vertical frames 15, 15 so as to communicate with the holding groove 14c of the lower frame 14.

[0027] 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.

[0028] 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.

[0029] As shown in Figures 3(b) and 5, the partition panel 10 (the panel main body 11 before the panel body 20 is attached) is provided with a receiving piece 22 that protrudes inward into the attachment opening 19 and against which the front edge 20a of the panel body 20 in the fitting direction abuts. The partition panel 10 is provided with a pressing member 26 that is attached to the attachment opening 19 so as to press the rear edge 20b of the panel body 20 in the fitting direction. With this configuration, the panel body 20 can be attached by attaching the pressing member 26 that presses the rear edge 20b of the panel body 20 to the attachment opening 19 with the front edge 20a of the panel body 20 abutting against the receiving piece 22. This makes it possible to easily attach the panel body 20 by fitting the panel body 20 into the attachment opening 19 and attaching the pressing member 26 to the attachment opening 19. In addition, the panel body 20 can be fixed by being sandwiched between the receiving piece portion 22 and the pressing member 26, and the fasteners for fixing the panel body 20 are not exposed, thereby improving the appearance.

[0030] One of the mounting opening 19 and the pressing member 26 is provided with a fitting recess 25 that opens in the panel thickness direction, into which a fitting protrusion 28 provided on the other of the mounting opening 19 and the pressing member 26 that protrudes in the panel thickness direction is fitted. With this configuration, the fitting protrusion 28 provided on the other of the mounting opening 19 and the pressing member 26 can be moved in the panel thickness direction to fit into the fitting recess 25 provided on the other of the mounting opening 19.

[0031] The receiving piece portion 22 is provided around substantially the entire periphery of the peripheral edge portion on one side in the panel thickness direction of the mounting opening 19. With this configuration, the peripheral end portion on one side in the panel thickness direction of the panel body 20 can be supported by the receiving piece portion 22 around substantially the entire periphery. When attached to the mounting opening 19, the pressing member 26 includes a pressing piece 27 that is positioned around substantially the entire periphery of the other side of the mounting opening 19 in the panel thickness direction. With this configuration, the pressing piece 27 can press the peripheral edge of the panel body 20 on the other side in the panel thickness direction around substantially the entire periphery. Furthermore, the receiving piece 22 and the pressing piece 27 are provided in a frame-like shape on the peripheral edges on both sides of the panel body 20 in the thickness direction, improving the appearance compared to a configuration in which they are provided with a space between them in the circumferential direction. Furthermore, the thickness dimension of the panel body 20 is substantially the same as the projected dimension of the frames (the lower frame 14, the horizontal frame 16, and the vertical frames 15, 15 on both sides) that define the mounting opening 19, giving the area where the panel body 20 is attached a solid and stable appearance.

[0032] The receiving piece portion 22 is attached to the mounting opening 19 so as to cover the receiving grooves 14a, 15a, 15a, and 16a provided on the inner peripheral surface of the mounting opening 19, and is provided on a panel receiving member 21 provided with a holding portion (fitting recess 25) that holds the pressing member 26. With this configuration, by attaching the panel receiving member 21 to the mounting opening 19 so as to cover the receiving grooves 14a, 15a, 15a, and 16a, it is possible to provide the receiving piece portion 22 against which the panel body 20 abuts. Furthermore, the pressing member 26 can be held in the fitting recess 25 that constitutes the holding portion of the panel receiving member 21. This allows the frame that defines the opening to which the light-transmitting plate 18 is attached and the frame that defines the mounting opening 19 to which the panel body 20 is attached to be made into a common component. The panel receiving member 21 is provided with an opposing surface 24 that is disposed so as to face the peripheral end surface 20c of the panel body 20, and a head receiving portion 23 that is provided in a stepped shape so as to be on the outer circumferential side of the opposing surface 24 and that receives the head of the fastener 9 that is fastened to the attachment object. With this configuration, it is possible to prevent the head of the fastener 9 that fixes the panel receiving member 21 to the attachment object from interfering with the peripheral end surface 20c of the panel body 20.

[0033] Specifically, the mounting opening 19 into which the panel body 20 is retrofitted at the construction site is bounded on all four sides by a lower frame 14, a horizontal frame 16 above it, and vertical frames 15, 15 on both sides, as shown in Figures 3(b) and 4. The panel receiving member 21 is provided along the upper surface of the lower frame 14, the lower surface of the horizontal frame 16, and the opposing side surfaces of the vertical frames 15, 15 on both sides, which constitute the inner peripheral surface of the mounting opening 19. The illustrated example shows an example in which the panel receiving members 21, 21 are provided so as to have a length that covers almost the entire length of the opposing side surfaces that constitute the inner peripheral surface of the mounting opening 19 of the vertical frames 15, 15 on both sides. Also shown is an example in which the panel receiving members 21, 21 have a length that covers the distance between the panel receiving members 21, 21 attached to the vertical frames 15, 15 on both sides, and are attached to the lower frame 14 and the horizontal frame 16. In other words, the illustrated example shows the panel receiving member 21 provided vertically along the inner peripheral surface of the mounting opening 19, but the present invention is not limited to this example.

[0034] The receiving piece portion 22 of the panel receiving member 21 is provided to protrude from the peripheral edge portion on one side of the inner peripheral surface of the mounting opening 19 in the panel thickness direction toward the center of the mounting opening 19 (the side of the panel receiving member 21 facing the panel receiving member 21). This receiving piece portion 22 is provided to protrude toward the center of the mounting opening 19 beyond the opposing surface 24 of the panel receiving member 21. The protrusion dimension of this receiving piece portion 22 from the opposing surface 24 may be set appropriately from the perspective of stably receiving the front edge portion 20a of the panel body 20, or from the perspective of appearance. The panel receiving member 21 is provided so that the surface of the receiving piece portion 22 facing outward in the panel thickness direction is generally flush with the surfaces of the lower frame 14, the vertical frames 15, 15 on both sides, and the horizontal frame 16, which are to be attached, facing outward in the panel thickness direction (one side). In other words, the receiving piece portions 22 of the panel receiving members 21 attached to each of the four inner peripheral surfaces of the mounting opening 19 are provided so that they are aligned in the panel thickness direction.

[0035] The head accommodation portion 23 of the panel receiving member 21 is located adjacent to the center of the receiving piece portion 22 in the panel thickness direction. The head accommodation portion 23 is groove-shaped and opens toward the center of the mounting opening 19 and extends the entire length of the panel receiving member 21. The groove bottom of this head accommodation portion 23 is defined by a bottom piece provided along the inner circumferential surface of the mounting opening 19. The panel receiving member 21 is attached to the mounting target (the lower frame 14, the vertical frames 15, 15 on both sides, and the horizontal frame 16) using a fastener 9 fastened via the bottom piece to one side of the mounting target in the panel thickness direction. The bottom piece may have an insertion hole for the fastener 9. The panel receiving member 21 may be attached to the panel main body 11 in advance at a factory, or may be attached to the panel main body 11 at a construction site after shipping from the factory. One side of the head accommodating section 23 in the groove width direction is defined by a base end portion of a receiving piece 22 that is provided so as to rise from one side edge of the bottom piece in the groove width direction toward the center of the mounting opening 19. A protrusion is provided at the base end portion of this receiving piece 22 against which the peripheral end surface 20c of the front edge 20a of the panel body 20 abuts. This protrusion is provided so that the surface facing the center of the mounting opening 19 is approximately flush with the opposing surface 24.

[0036] The other side of the head accommodating section 23 in the groove width direction is arranged to protrude from the other side edge of the bottom piece in the groove width direction toward the center of the mounting opening 19, and the tip surface in the protruding direction is defined by the step wall surface of the protruding step section that constitutes the opposing surface 24. The protruding portion of the panel receiving member 21 is provided so as to cover the receiving grooves 14a, 15a, 15a, and 16a and to be located at the center of the inner peripheral surface of the mounting opening 19 in the panel thickness direction. This protruding portion is provided so that a head receiving portion 23 can be formed on one side in the panel thickness direction and a pressing member 26 (described later) can be disposed on the other side in the panel thickness direction. This protruding portion is provided with a fitting recess 25 that opens toward the other side in the panel thickness direction. The fitting recess 25 is groove-shaped and extends the entire length of the panel receiving member 21. Locking protrusions that protrude in directions facing each other are provided at midpoints in the groove depth direction on both inner walls of this fitting recess 25. The illustrated example shows an example in which a hollow portion that penetrates the entire length is provided at one side of the fitting recess 25 in the panel thickness direction in the protruding portion. The panel receiving member 21 of the lower frame 14 is attached to the lower frame 14 so that the insertion hole 14b of the lower frame 14 is exposed.

[0037] 2 and 3, the pressing members 26 are attached to the panel receiving member 21 so as to extend along the upper surface of the lower frame 14, the lower surface of the horizontal frame 16, and the opposing side surfaces of the vertical frames 15, 15 on both sides, which constitute the inner peripheral surface of the mounting opening 19, similarly to the panel receiving member 21. The illustrated example shows an example in which the pressing members 26, 26 extend over substantially the entire length of the opposing side surfaces that constitute the inner peripheral surface of the mounting opening 19 of the vertical frames 15, 15 on both sides (see also FIG. 1). Also shown is an example in which the pressing members 26, 26 extend between the pressing members 26, 26 attached to the panel receiving members 21, 21 of the vertical frames 15, 15 on both sides, and are attached to the panel receiving members 21, 21 of the lower frame 14 and the horizontal frame 16. In other words, similarly to the panel receiving member 21 described above, the pressing members 26 are attached vertically along the inner peripheral surface of the mounting opening 19, but the present invention is not limited to this example. This pressing member 26 is attached to the panel receiving member 21 so that the surface of the main body, which is approximately rectangular when viewed in the longitudinal direction, facing the inner peripheral surface of the mounting opening 19 abuts against the inner peripheral surface, and the surface facing the center of the mounting opening 19 is approximately flush with the opposing surface 24 of the panel receiving member 21. The illustrated example shows an example in which a hollow portion is provided through the main body over its entire length.

[0038] The fitting protrusion 28 of the pressing member 26 is provided so as to protrude from the main body portion toward one side in the panel thickness direction. Locking portions that lock onto the locking protrusions of the fitting recess 25 are provided on both outer surfaces of this fitting protrusion 28. In the illustrated example, the fitting protrusion 28 is composed of a pair of protruding pieces that are inserted along both inner walls of the fitting recess 25 in the groove width direction. The fitting protrusion 28 may be configured to be fitted into the fitting recess 25 so as not to be easily detached. When this pressing member 26 is attached to the panel receiving member 21 by fitting the fitting protrusion 28 into the fitting recess 25, the surface of the main body facing outward in the panel thickness direction is configured to be roughly flush with the surface of the panel receiving member 21 facing outward (the other side) in the panel thickness direction of the object to be attached.

[0039] The pressing piece 27 is provided so as to protrude toward the center of the mounting opening 19 from an edge of the main body that is on the outer side in the panel thickness direction and that is closer to the center of the mounting opening 19. The protruding dimension of this pressing piece 27 from the main body may be set to an appropriate dimension from the viewpoint of stably holding the rear edge 20b of the panel body 20, from the viewpoint of appearance, etc. The illustrated example shows an example in which the protruding dimension of the pressing piece 27 from the main body and the protruding dimension from the opposing surface 24 of the receiving piece 22 of the panel receiving member 21 are approximately the same. With this configuration, the appearance of the peripheral edge of the panel body 20 can be made approximately the same on both sides in the panel thickness direction. A cushioning material 29 may be provided at the recessed corner between the pressing piece 27 and the main body, as shown by the two-dot chain line in Figures 3(b) and 5, which comes into contact with the rear edge 20b of the panel body 20 while undergoing compressive deformation. This configuration can prevent the panel body 20 from rattling when attached to the attachment opening 19. The cushioning material 29 may be provided so as to extend over the entire length of the pressing member 26, or may be provided at multiple locations spaced apart in the longitudinal direction.

[0040] The panel receiving member 21 and the pressing member 26 may be extrusion molded products made of a metal material or a synthetic resin material with a substantially uniform cross-sectional shape along their entire length, similar to the four-perimeter frame 12. The surfaces of the panel receiving member 21 and the pressing member 26 may be decorative surfaces that have been subjected to an appropriate surface treatment such as painting or applying a decorative sheet, similar to the four-perimeter frame 12. The surfaces of the panel receiving member 21 and the pressing member 26 may be decorative surfaces with the same color tone or pattern as the four-perimeter frame 12.

[0041] As shown in Figures 1 to 3, the panel body 20 has a rectangular flat plate shape. The panel body 20 is attached to the attachment opening 19 so that the four front edge portions 20a abut against or are close to the four receiving pieces 22 and the four rear edge portions 20b abut against or are close to the four pressing pieces 27. The panel body 20 is attached to the attachment opening 19 with its lower peripheral end face 20c abutting against the opposing surface 24 of the panel receiving member 21 of the lower frame 14 and the upper surface of the main body of the pressing member 26. The panel body 20 is attached to the attachment opening 19 with its upper peripheral end face 20c abutting against the opposing surface 24 of the panel receiving member 21 of the horizontal frame 16 and the lower surface of the main body of the pressing member 26. The panel body 20 is attached to the attachment opening 19 with its peripheral end surfaces 20c on both sides of the panel width abutting or in close proximity to the opposing surfaces 24 of the panel receiving members 21 of the vertical frames 15, 15 and the side surfaces of the main body of the pressing member 26.

[0042] The thickness dimension of this panel body 20 corresponds to the dimension along the panel thickness direction from the receiving piece portion 22 to the pressing piece portion 27 so that it can be attached to the attachment opening 19 as described above. The dimension along the up-down direction of this panel body 20 corresponds to the dimension from the opposing surface 24 of the lower frame 14 to the opposing surface 24 of the horizontal frame 16 so that it can be attached to the attachment opening 19 as described above. The dimension along the panel width direction of this panel body 20 corresponds to the dimension between the opposing surfaces 24, 24 of the vertical frames 15, 15 on both sides so that it can be attached to the attachment opening 19 as described above. In the illustrated example, the dimension along the up-down direction of the panel body 20 is greater than the dimension along the panel width direction, but this is not limited to this example. The panel body 20 may be a decorative panel in which a suitable rectangular flat substrate has been subjected to a surface decorative treatment such as application of a decorative sheet or painting on both thickness-wise sides thereof. The panel body 20 is not limited to a solid plate configuration, but may be a so-called flush panel configuration in which a surface panel is attached to a frame-shaped core material. Furthermore, the panel body 20 is not limited to an opaque rectangular flat plate configuration, but may be a transom-shaped or louver-shaped configuration with through holes, slits, etc.

[0043] As shown in Figure 4, the method for installing the partition panel 10 configured as described above includes a step of installing the panel body 11, to which the horizontal frames 16 and the light-transmitting plates 18 are attached, within the four-perimeter frame 12. With this configuration, the panel body 11 can be installed with the light-transmitting plates 18 attached, which is difficult to handle, and handling can be improved. At this time, the upper end of the panel body 11 may be inserted into the recess of the upper guide 4, and the lower guide 5 may be received in the holding groove 14c at the lower end, and the panel body 11 may be temporarily held by these upper guide 4 and lower guide 5. In the process of installing the panel body 11, the fasteners 9, 9 are fastened to the respective fixing targets by penetrating the upper frame 13 and the lower frame 14 of the panel body 11, thereby installing the panel body 11. With this configuration, the top and bottom of the panel body 11 can be stably fixed to the respective fixing targets by the fasteners 9, 9. In the illustrated example, the upper frame 13 is fixed to the ceiling 2 by fastening the fasteners 9 to a target on the ceiling 2 side via the insertion holes 13b of the upper frame 13. Also, the lower frame 14 is fixed to the floor 3 by fastening the fasteners 9 to a target on the floor 3 side via the insertion holes 14b of the lower frame 14.

[0044] This installation method includes a step of fitting and installing a panel body 20 into a mounting opening 19 defined by the lower frame 14 as a fixing target frame constituting at least one of the upper frame 13 and the lower frame 14 and the horizontal frame 16. This installation method is configured to fit and install the panel body 20 into the mounting opening 19 so as to cover the insertion hole 14b, which is the penetration portion of the fastener 9 in the lower frame 14. With this configuration, a thicker panel body 20 can be attached after the fact, so to speak, and this also allows the lower frame 14 to be stably fixed to the fixing target by the fastener 9. In other words, after the lower frame 14 is fixed to the floor 3 side by the fastener 9, the panel body 20 can be attached so as to cover the insertion hole 14b of the fastener 9.

[0045] 3(b) and 5, in this installation method, the panel body 20 is fitted into the mounting opening 19, and its front edge 20a is brought into contact with the receiving piece 22. Next, a pressing member 26 that presses down on the rear edge 20b of the panel body 20 is attached to the mounting opening 19, and the panel body 20 is attached. At this time, a backing plate or the like may be placed on the surface of the pressing member 26 facing outward in the panel thickness direction, and the pressing member 26 may be hammered in with a hammer or the like to fit its fitting protrusion 28 into the fitting recess 25 of the panel receiving member 21. The construction procedure for the partition panel 10 is not limited to the above-described configuration, and various other configurations can be adopted.

[0046] The panel receiving member 21 and the pressing member 26 are not limited to the above-described configuration. In the above example, the panel receiving member 21 is provided with the head receiving portion 23 that is stepped downward from the opposing surface 24, but such a head receiving portion 23 may not be provided. In the above example, the receiving piece portion 22 is attached to the mounting opening 19 so as to cover the receiving grooves 14a, 15a, 15a, and 16a, and is provided on the panel receiving member 21 provided with a holding portion (fitting recess 25) that holds the pressing member 26, but this is not limited to this example. For example, the receiving piece portion 22 and the holding portion (fitting recess 25) may be provided separately, or one or both of them may be provided integrally on the inner circumferential surface of the mounting opening 19. In the above example, the receiving piece portion 22 is provided around substantially the entire periphery of the peripheral edge of the mounting opening 19 on one side in the panel thickness direction, and the pressing piece portion 27 is provided around substantially the entire periphery of the peripheral edge of the mounting opening 19 on the other side in the panel thickness direction, but this is not limited to this example. One or both of the receiving piece portion 22 and the pressing piece portion 27 may be provided at multiple locations spaced apart in the circumferential direction around the peripheral edge of the mounting opening 19, for example. Also, one or both of the receiving piece portion 22 and the pressing piece portion 27 may be provided only on the upper and lower edges of the mounting opening 19 or only on both edges in the panel width direction.

[0047] In the above example, the fitting recess 25 is provided on the mounting opening 19 side and the fitting protrusion 28 is provided on the pressing member 26 side, but this is not limited to this example. A configuration in which a fitting protrusion is provided on the mounting opening 19 side and a fitting recess is provided on the pressing member 26 side may also be used. The pressing member 26 is not limited to being attached to the mounting opening 19 by fitting the fitting protrusion into the fitting recess. The pressing member 26 may also be attached to the mounting opening 19 using an adhesive, a pressure-sensitive adhesive, a fastener, or the like. Furthermore, such a pressing member 26 and receiving piece 22 may not be provided. In this case, the panel body 20 may be configured to be attached by being press-fitted into the mounting opening 19, or may be attached to the mounting opening 19 using an adhesive, a pressure-sensitive adhesive, a fastener, or the like. In the above example, the fixed target frame is the lower frame 14, and the panel body 20 is provided at the lower end portion of the partition panel 10, but this is not a limitation. Instead of or in addition to this example, the fixed target frame may be the upper frame 13, and the panel body 20 may be provided at the upper end portion of the partition panel 10. The configurations of the respective members and parts of the partition panel 10 and the partition wall device 1 equipped therewith according to this embodiment are not limited to the configurations described above, and various other modifications are possible.
