Description

[Technical field]

[0001] The present invention relates to curtain walls or sashes. [Background technology]

[0002] The curtain wall that constitutes the exterior wall of a building is made up of a series of alternating vision and spandrel sections in the vertical direction. The vision section is a window section that faces the living space between the floor and ceiling. The spandrel section is formed between the ceiling of the lower floor and the floor of the upper floor, facing the space at the boundary between the upper and lower floors.

[0003] Patent Document 1 discloses a curtain wall in which a main unit having a fireproof board and a power generation unit having a solar cell panel are attached to a mullion that is the framework of a building. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 8-172211 Summary of the Invention [Problem to be solved by the invention]

[0005] The power generation unit of Patent Document 1 has a structure in which a glass plate and a solar cell panel arranged on the indoor side of the glass plate are integrally connected by a frame. With this structure, for example, when performing maintenance such as replacing a solar cell panel that has deteriorated over time, it is necessary to remove the entire power generation unit including the glass plate from the outdoor side. This maintenance work requires, for example, the installation of scaffolding on the exterior wall of the building, which is time-consuming. Furthermore, with this structure, the curtain wall temporarily loses its function as an exterior wall during maintenance, and measures against this are also necessary.

[0006] Thus, in a curtain wall, for example, when solar panels are installed in the space inside the room rather than the exterior glass, maintainability becomes an issue. Note that there is also a demand for installing functional components other than power generating materials such as solar panels in this space, such as lighting equipment, advertising boards, or various panel materials for decorating the building, and in such cases maintainability becomes an issue as well. It is also assumed that such functional components will be installed in sashes such as stepped windows with openings lined up above and below, in the same way as in the case of curtain walls, and maintainability becomes an issue in such cases as well.

[0007] The present invention has been made in consideration of the problems with the conventional technology described above, and has an object to provide a curtain wall or sash that can improve the workability of maintenance work on functional components. [Means for solving the problem]

[0008] A curtain wall or sash according to one embodiment of the present invention is a curtain wall or sash comprising a first opening facing the living space of a building and a second opening facing the boundary between upper and lower floors of the building, wherein the second opening comprises a first frame body having a first upper frame and a first lower frame and supporting glass, a second frame body arranged on the indoor side of the first frame body and having a second upper frame and a second lower frame, a functional member arranged on the indoor side of the glass, and an attachment member provided between the first frame body and the second frame body and detachably supported on at least one of the second upper frame and the second lower frame, thereby being movable in the vertical direction. Effect of the Invention

[0009] According to the above-described aspects of the present invention, the workability of the maintenance work for the functional components can be improved. [Brief description of the drawings]

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A curtain wall or sash according to the present invention will be described in detail below with reference to preferred embodiments and the accompanying drawings.

[0012] In the following, an embodiment of the present invention will be described by taking a curtain wall constituting the exterior wall of a building as an example, but the present invention can also be used for sashes such as stepped windows with openings arranged vertically. In other words, the present invention is suitable as a mounting attached to a building such as a curtain wall constituting the exterior wall of a building or a sash installed on the exterior wall of a building. As shown in Figures 1 and 2, a curtain wall 10 according to the first embodiment forms the exterior wall of a building such as a building. The curtain wall 10 includes a spandrel portion 11 and a vision portion 12 adjacent to each other vertically. In the curtain wall 10, the spandrel portion 11 and the vision portion 12 are arranged vertically and horizontally, so that the spandrel portion (second opening) 11 and the vision portion (first opening) 12 are arranged alternately in the vertical direction. The vision portion 12 is a window portion facing the living space of the building. The spandrel portion 11 faces the boundary portion between the upper and lower floors (upper and lower floor boundary portion), that is, the attic space or the underfloor space.

[0013] First, an example of the overall configuration of the curtain wall 10 will be described.

[0014] As shown in Figures 1 to 4, the spandrel portion 11 comprises a first unit 11A having a first frame body 14, and a second unit 11B having a second frame body 15 and arranged on the indoor side of the first unit 11A. The spandrel portion 11 further comprises upper and lower attachment members 16a, 16b and upper and lower auxiliary attachment members 17a, 17b supported between the frames 14, 15. The spandrel portion 11 supports glass 18, a functional member 20 arranged on the indoor side of the glass 18, and a fireproof board 22 arranged on the indoor side of the functional member 20 by means of these frames 14, 15, attachment members 16a, 16b, and auxiliary attachment members 17a, 17b.

[0015] The first unit 11A has glass 18 supported on the inside of a first frame 14. The first frame 14 has an upper frame (first upper frame) 14a, a lower frame (first lower frame) 14b, and left and right vertical frames 14c, 14d. The glass 18 is formed of, for example, a float glass sheet, and is disposed on the outermost side of the spandrel portion 11. Each of the frames 14a to 14d is an extruded shape made of metal including, for example, aluminum.

[0016] In this application, the "visible direction" refers to the indoor / outdoor direction of the curtain wall 10, that is, the direction from the indoor side to the outdoor side or the opposite direction (the direction indicated by the arrow Z in the figure), and the "visible surface" refers to a surface extending along the visible direction. The "visible direction" refers to a direction perpendicular to the visible direction, and in the case of a vertical frame 14c that is long in the vertical direction, it refers to the left-right direction perpendicular to the longitudinal direction (the direction indicated by the arrow X in the figure), and in the case of an upper frame 14a that is long in the horizontal direction, it refers to the up-down direction perpendicular to the longitudinal direction (the direction indicated by the arrow Y in the figure). The "visible surface" refers to a surface along the visible direction. The "inside of the frame" refers to the inside part of the first frame body 14, which is a frame-shaped member. The "outside of the frame" refers to the outside part of the first frame body 14, which is a frame-shaped member.

[0017] As shown in Fig. 2, the upper frame 14a extends horizontally and connects the upper ends of the left and right vertical frames 14c, 14d. The upper frame 14a has a protruding piece that protrudes from the upper end of the exterior-facing surface to the exterior, and a ridge 24a with a generally L-shaped cross section is connected to this protruding piece. A downward opening groove 25 is formed between the exterior-facing surface of the upper frame 14a and the ridge 24a. The upper edge of the glass 18 is inserted into and held in the opening groove 25.

[0018] The bottom frame 14b extends horizontally and connects the lower ends of the left and right vertical frames 14c, 14d. The bottom frame 14b has a protruding piece that protrudes from the lower end of the exterior facing surface to the outside of the room, and a roughly L-shaped ridge 24b is connected to this protruding piece. An upward opening groove 26 is formed between the exterior facing surface of the bottom frame 14b and the ridge 24b. The lower edge of the glass 18 is inserted into and held in the opening groove 26.

[0019] As shown in Fig. 4, the left and right vertical frames 14c, 14d extend in the up-down direction. The vertical frames 14c, 14d have protruding pieces that protrude to the outside from the lower ends of the exterior ends of the visible faces facing the inside of the frame, and the battens 24c, 24d, which have a generally L-shaped cross section, are connected to these protruding pieces. A horizontal opening groove 27 is formed between the exterior visible faces of the vertical frames 14c, 14d and the battens 24c, 24d. The side edges of the glass 18 are inserted into and held in the opening grooves 27.

[0020] The second unit 11B has a fireproof board 22 supported on the inside of the second frame 15. The second frame 15 has an upper frame (second upper frame) 15a, a lower frame (second upper frame) 15b, and left and right mullions 28, 28. The fireproof board 22 is a board for heat insulation and fire resistance, such as a calcium silicate board. The frames 15a, 15b and the mullions 28 are extruded shapes of metal including aluminum, for example. The connection between the fireproof board 22 and the second frame 15 and the surrounding area are filled with a fireproof material 30, such as a sprayed rock wall.

[0021] As shown in Fig. 2, the upper frame 15a extends in the horizontal direction. A bracket 31 is fixed with a screw to the visible surfaces of the left and right mullions 28, 28, respectively. The bracket 31 is made of metal sheet metal such as steel, stainless steel, or aluminum bent into a roughly L-shape, and is arranged along the indoor-outdoor direction. The plate portion of the bracket 31 along the up-down direction is fixed to the visible surface of the mullions 28. Both longitudinal ends of the upper frame 15a are fixed with a screw to the plate portions along the left-right direction of the left and right brackets 31, respectively. In this way, the upper frame 15a is installed across the left and right mullions 28, 28.

[0022] The upper frame 15a has, in order from top to bottom, a base portion 32a, a hollow portion 32b, and a sight piece 32c. The base portion 32a is formed in a substantially U-shaped cross section and opens upward. The base portion 32a has an inner space in which a fireproof material 30 is installed between a pair of standing pieces protruding upward from each end in the indoor / outdoor direction. The plate portion along the left and right direction of the bracket 31 is inserted into this inner space and fixed. The protruding ends of the pair of standing pieces of the base portion 32a are respectively formed with bent pieces 32d that are bent inwardly and face each other. The hollow portion 32b is formed in a substantially rectangular cross section and is provided at the outdoor end of the lower wall of the base portion 32a. The sight piece 32c is a plate piece that protrudes downward from the outdoor end of the lower wall of the hollow portion 32b. A substantially crank-shaped bracket 32e is screwed to the outdoor-side sight surface of the hollow portion 32b. The upper frame 15a forms a downwardly facing open groove 34 between the sight piece 32c and the bracket 32e. The open groove 34 receives and holds the upper edge of the fireproof board 22.

[0023] As shown in Fig. 2, the lower frame 15b can be vertically symmetrical to the upper frame 15a. Therefore, the components of the lower frame 15b are given the same reference numerals as the components of the upper frame 15a, and detailed descriptions are omitted. That is, the lower frame 15b also has a base portion 32a, a hollow portion 32b, a sight piece 32c, a bent piece 32d, a bracket 32e, and an opening groove 34. The lower frame 15b is also provided using a bracket 31, similar to the upper frame 15a, so as to span between the left and right mullions 28, 28. The lower edge of the fireproof board 22 is inserted into and held in the opening groove 34 of the lower frame 15b.

[0024] In the lower frame 15b, a generally L-shaped bracket 36 is screwed to the lower end of the indoor facing surface of the base portion 32a. The bracket 36 is connected to a blind box 37. The upper ends of the blinds 37a installed in the vision unit 12 are attached to the blind box 37 (see FIG. 5). A ceiling panel 38 is connected to the indoor end of the blind box 37.

[0025] As shown in Fig. 4, the uprights 28 are vertical members that extend along the vertical direction of the building and are arranged side by side at a predetermined interval in the horizontal direction. The uprights 28 function as the vertical frame of the second frame body 15 that connects the upper frame 15a and the lower frame 15b. A pair of left and right abutment pieces 28a, 28a that protrude toward the outside of the room are provided on the interior facing surface of the uprights 28. Each abutment piece 28a abuts against the interior facing surfaces of the vertical frames 14c, 14d of the first frame body 14. The gap between the abutment pieces 28a and the vertical frames 14c, 14d is airtightly sealed with airtight material 28b. A reinforcing material 39 is inserted into the hollow portion of the uprights 28.

[0026] A bracket 40 is screwed to the visible surface of the mullion 28 near its exterior end. The bracket 40 is made of sheet metal such as steel, stainless steel or aluminum bent into a roughly L-shape and is arranged in the vertical direction. The plate portion of the bracket 40 that runs along the indoor / outdoor direction is fixed to the visible surface of the mullion 28. The plate portion of the bracket 40 that runs along the left / right direction is fixed to the upper and lower frames 15a, 15b of the first frame 14 and the upper and lower frames 48a, 48b of the vision section 12 described below (see Figure 2).

[0027] A pair of brackets 42a, 42b are screwed to the front surface of the mullion 28 near its interior end in the front direction. The brackets 42a, 42b are made of metal sheet metal such as steel, stainless steel, or aluminum bent into a roughly L-shape and extend in the vertical direction. The plate portions of the brackets 42a, 42b that run along the indoor / outdoor direction are fixed to the front surface of the mullion 28. The plate portions of the brackets 42a, 42b that run along the left / right direction protrude from the front surface of the mullion 28 and form a horizontal opening groove 43 between them. The side edge of the fireproof board 22 is inserted and held in the opening groove 43. The interior front surface of the mullion 28 is fixed to the building frame using fasteners 44, for example.

[0028] As shown in Fig. 2, the upper attachment member 16a extends in the horizontal direction. The attachment member 16a is disposed between the upper frame 15a and the auxiliary attachment member 17a, and is supported by the upper frame 15a and the auxiliary attachment member 17a. As a result, the attachment member 16a is provided across the left and right uprights 28, 28.

[0029] The attachment member 16a has, from top to bottom, a base portion 46a, a hollow portion 46b, and a protruding piece 46c. The base portion 46a is formed with a substantially U-shaped cross section and opens upward. The base portion 46a has an inner space in which the fireproof material 30 is installed between a pair of upright pieces protruding upward from each end in the indoor / outdoor direction. This inner space and the hollow portion 46b also function as escape holes for the screws that fix the bracket 40 to the visible surface of the mullion 28. The protruding ends of the pair of upright pieces of the base portion 46a are respectively formed with bent pieces 46d that are bent outwardly and spaced apart from each other. The hollow portion 46b is formed with a substantially rectangular cross section and is provided on the back side of the lower wall of the base portion 46a. The protruding piece 46c is a fin-shaped plate piece that protrudes downward from the visible surface on the lower side of the attachment member 16a. The protruding piece 46c engages with a holding frame 54 (upper holding frame 54a) which holds the outer peripheral edge of the functional member 20 described below, thereby positioning it in the projection direction.

[0030] 2, the lower attachment member 16b can be vertically symmetrical to the upper attachment member 16a. Therefore, the components of the attachment member 16b are given the same reference numerals as those of the attachment member 16a, and detailed descriptions thereof will be omitted. That is, the attachment member 16b also has a base portion 46a, a hollow portion 46b, a protruding piece 46c, and a bent piece 46d.

[0031] The attachment member 16b is also disposed between the lower frame 15b and the auxiliary attachment member 17b, and is supported by the lower frame 15b and the auxiliary attachment member 17b. The attachment member 16b in this embodiment is provided between the lower frame 15b and the auxiliary attachment member 17b so as to be detachable from each other and to be movable relative to each other in the vertical direction. The detailed configuration of the attachment member 16b and its surroundings will be described later.

[0032] As shown in Fig. 2, the upper auxiliary attachment member 17a extends laterally and has a generally U-shaped cross section. The auxiliary attachment member 17a is disposed between the upper frame 14a and the attachment member 16a, and is fixed to the bracket 40 together with the upper frame 14a. This allows the auxiliary attachment member 17a to be provided across the left and right uprights 28, 28. The auxiliary attachment member 17a can also connect the upper frame 14a to a lower frame 48b of a third frame body 48, which will be described later.

[0033] 2, the lower auxiliary attachment member 17b can be vertically symmetrical to the upper auxiliary attachment member 17a. That is, the auxiliary attachment member 17b is disposed between the lower frame 14b and the attachment member 16b, and is fixed to the bracket 40 together with the lower frame 14b. The auxiliary attachment member 17b can also connect the lower frame 14b to an upper frame 48a of a third frame body 48, which will be described later.

[0034] In other words, the attachment members 16a and 16b and the auxiliary attachment members 17a and 17b constitute a part of the second unit 11B. In this case, it can be said that the second unit 11B is connected to the first unit 11A via the auxiliary attachment members 17a and 17b located on the outermost side of the room.

[0035] As shown in FIG. 2, the vision section 12 includes a third frame body 48 and a double glazing (vision section glass) 50.

[0036] The third frame 48 has an upper frame (third upper frame) 48a, a lower frame (third lower frame) 48b, and left and right vertical frames 48c, 48d. Each of the frames 48a to 48d is an extruded material of metal including, for example, aluminum. The insulating glass 50 is configured by arranging two pieces of glass 50a, 50b with a spacer in between. The glasses 50a, 50b are formed of, for example, float glass sheets. The insulating glass 50 is disposed on the outermost side of the vision section 12. Each of the frames 48a to 48d is an extruded material of metal including, for example, aluminum.

[0037] The upper frame 48a extends horizontally and connects the upper ends of the left and right vertical frames 48c, 48d. The upper frame 48a has an opening groove 51a at the outdoor end of the visible surface facing the inside of the frame. The opening groove 51a is a downward groove portion. The upper edge of the double-glazed glass 50 is inserted and held in the opening groove 51a. The lower frame 48b extends horizontally and connects the lower ends of the left and right vertical frames 48c, 48d. The lower frame 48b has an opening groove 51b at the outdoor end of the visible surface facing the inside of the frame. The opening groove 51b is an upward groove portion. The lower edge of the double-glazed glass 50 is inserted and held in the opening groove 51b. The vertical frames 48c, 48d can have the same or similar cross-sectional shape as the frames 48a, 48b. The vertical frames 48c, 48d extend in the vertical direction and hold the side edges of the insulating glass 50, respectively.

[0038] As shown in FIG. 2, the upper frame 48a of the third frame body 48 is adjacent to the lower frame 14b of the first frame body 14. The upper frame 48a and the lower frame 14b have their facing surfaces waterproofed by seals 52a, 52b arranged in the indoor / outdoor direction. Similarly, the lower frame 48b of the third frame body 48 is adjacent to the upper frame 14a of the first frame body 14, and the seals 52a, 52b waterproof the space between them. A frame material 53 is connected to the upper end of the indoor facing surface of the lower frame 48b. The frame material 53 connects the floor, which is a floor slab attached to the building frame and has floor panels on it, and covers the upper part of the upper frame 15a, the attachment member 16a, and the auxiliary attachment member 17a.

[0039] Next, the functional member 20 is, for example, a film-like or sheet-like solar cell (power generating material). The functional member 20 may be other than a power generating material, and examples thereof include lighting equipment, advertising boards, and various panel materials for decorating buildings. As shown in FIG. 2, the functional member 20 is installed in an enclosed space of the spandrel portion 11 formed between the glass 18 and the fireproof board 22. The functional member 20 of this embodiment is a power generating material composed of a solar cell, and generates power by receiving light transmitted through the glass 18. The functional member 20 is formed, for example, in a thin film or sheet shape, and therefore has poor self-supporting ability. Therefore, the outer peripheral edge portion (four peripheral edges) of the functional member 20 is held by a holding frame 54.

[0040] 2 to 4, the holding frame 54 has an upper holding frame 54a, a lower holding frame 54b, and left and right vertical holding frames 54c and 54d. Each of the holding frames 54a to 54d is an extruded member of a metal including, for example, aluminum. Each of the holding frames 54a to 54d has the same cross-sectional shape. Each of the holding frames 54a to 54d has an engagement groove 56 on the projection surface on the outside of the frame, and a holding groove 57 on the projection surface on the inside of the frame.

[0041] The engagement groove 56 of the upper holding frame 54a can be engaged with and disengaged from the protruding piece 46c of the upper attachment member 16a (see Figs. 2 and 5). The upper holding frame 54a is positioned in the projection direction by engaging with the protruding piece 46c. The engagement groove 56 of the lower holding frame 54b is engaged with the protruding piece 46c of the lower attachment member 16b and is fastened and fixed using a screw 58 (see Figs. 2, 3 and 5). The screw 58 may be provided at multiple positions in the longitudinal direction (X direction) of the lower holding frame 54b. The engagement grooves 56 of the vertical holding frames 54c and 54d are engaged with protruding pieces 59 provided on the projection surface of the upright 28, respectively, to be positioned in the projection direction, and are guided to be movable along the vertical direction (see Fig. 4). The protruding piece 59 shown in Fig. 4 is configured by fixing an L-shaped metal plate to the projection surface of the upright 28, but it may be formed integrally with the upright 28 like the other protruding pieces 46c. The edges of the functional members 20 are inserted into the respective retaining grooves 57 and are retained therein via, for example, a rubber gasket.

[0042] Next, a specific example of the configuration of the attachment member 16b and its surroundings will be described.

[0043] As described above, the lower attachment member 16b is provided between the bottom frame 15b and the auxiliary attachment member 17b so as to be detachable from each other and to be movable in the vertical direction relative to each other. Therefore, it can also be said that the second unit 11B of this embodiment has a three-part structure in which the cross member constituting at least the lower part of the spandrel portion 11 has the bottom frame 15b, the attachment member 16b, and the auxiliary attachment member 17b. The attachment member 16b may be supported only by the bottom frame 15b.

[0044] As shown in Fig. 3, the attachment member 16b has a cross-sectional shape that is tapered or trapezoidal, tapering from bottom to top. The lower end of the attachment member 16b is provided with bent pieces 46d, 46d that protrude like flanges at both indoor and outdoor ends. The outdoor-side bent piece 46d abuts against the lower surface of the auxiliary attachment member 17b and is fixed to the auxiliary attachment member 17b using a screw 60. The indoor-side bent piece 46d abuts against the lower surface of the outdoor-side bent piece 32d of the lower frame 15b and is fixed to the lower frame 15b using a screw 61. The screws 60, 61 may be provided at multiple positions in the longitudinal direction (X direction) of the attachment member 16b.

[0045] The attachment member 16b further has a pair of engagement pieces 46e, 46f and a pair of wiring holes 46g, 46g.

[0046] The engagement piece 46e is provided at the upper end of the exterior facing surface of the attachment member 16b, and has a claw shape bent upward. An engagement piece 62 is provided at the upper end of the interior facing surface of the auxiliary attachment member 17b. The engagement piece 62 has a claw shape bent downward. The engagement piece 46e can be engaged with and disengaged from the engagement piece 62 from below. The engagement piece 46f is provided at the upper end of the interior facing surface of the attachment member 16b, and has a claw shape bent upward. An engagement piece 32f is provided at the top of the exterior facing surface of the bottom frame 15b. The engagement piece 32f has a claw shape bent downward. The engagement piece 46f can be engaged with and disengaged from the engagement piece 32f from below.

[0047] The wiring holes 46g are provided to penetrate the upper and lower wall portions that form the hollow portion 46b, and are lined up one above the other. In other words, the wiring holes 46g penetrate the attachment member 16b from top to bottom. The lower wiring hole 46g communicates with the sealed space of the spandrel portion 11. The lower wiring hole 46g communicates with the inner space of the base portion 46a. A wiring hole 32g is also formed to penetrate the indoor facing surface of the base portion 32a of the lower frame 15b.

[0048] As shown in FIG. 3, a cover member 63 can be disposed directly below the attachment member 16b. The cover member 63 is an extrusion of metal, such as aluminum, and is a plate-shaped member extending laterally. The cover member 63 covers the lower part of the lower frame 15b, the attachment member 16b, and the auxiliary attachment member 17b. The outer end of the cover member 63 is rotatably connected to the lower surface of the auxiliary attachment member 17b using a hinge 63a. The inner end of the cover member 63 is abutted against the lower surface of the bent piece 32d on the indoor side of the lower frame 15b, and is fastened to the bent piece 32d with a screw 64. This allows the cover member 63 to easily open and close the lower part of the lower frame 15b, the attachment member 16b, and the auxiliary attachment member 17b by attaching and detaching the screw 64 (see FIG. 5). Reference numeral 64a in FIG. 3 denotes a cap that closes a hole through which a tool for operating the screw 64 or the screw 64 itself is passed when attaching and detaching it. The cover member 63 may be omitted.

[0049] As shown in FIG. 3, a wire 66 is passed through the attachment member 16b. A wire 67 is passed between the blind box 37 and the fireproof board 22 and the lower frame 15b. One end of the wire 66 passes through the wiring hole 46g and is connected to the lower end of the functional member 20, and the other end is electrically connected to the wire 67 by a connection part 68. The wire 66 has a stretchable extra length 66a wound in a spiral shape around a portion along the indoor-outdoor direction below the attachment member 16b. One end of the wire 67 passes through the wiring hole 32g and is connected to the wire 66 by a connection part 68, and the other end is passed from the upper side of the blind box 37 into the attic space and connected to the power source of the building. The wire 67 has a stretchable extra length 67a wound in a spiral shape around a portion along the vertical direction between the blind box 37 and the fireproof board 22 and the lower frame 15b.

[0050] When the attachment member 16b is moved to the uppermost position relative to the auxiliary attachment member 17b and the lower frame 15b, as shown in Figures 2 and 3, the engagement pieces 46e, 46f engage with the engagement pieces 62, 32f from below. Furthermore, the bent pieces 46d, 46d abut against the auxiliary attachment member 17b and the bent piece 32d. The bent pieces 46d, 46d of the attachment member 16b are fastened to the auxiliary attachment member 17b and the lower frame 15b with screws 60, 61. As a result, the attachment member 16b is detachably connected to the lower frame 15b and the auxiliary attachment member 17b so as to complement each other.

[0051] As shown in FIG. 5, the attachment member 16b can be easily pulled down from the lower frame 15b and the auxiliary attachment member 17b, that is, toward the vision unit 12, by removing the screws 60 and 61. At this time, the excess lengths 66a and 67a of the wiring 66 and 67 are extended, so that it is possible to suppress defects such as disconnection and damage caused by excessive load. Since the connection part 68 of the curtain wall 10 is exposed on the lower side of the attachment member 16b and the lower frame 15b, the wiring 66 and 67 can be easily connected and disconnected (disconnected). In addition, the curtain wall 10 of this embodiment covers the lower side of the attachment member 16b with a cover member 63. Therefore, it is recommended to remove the screw 64 and open the cover member 63 before attaching or detaching the attachment member 16b.

[0052] In this embodiment, the upper frame 15a, the attachment member 16a, and the auxiliary attachment member 17a have a vertically symmetrical structure with the lower frame 15b, the attachment member 16b, and the auxiliary attachment member 17b described above. Therefore, the attachment member 16a is also detachable from the upper frame 15a and the auxiliary attachment member 17a with a structure similar to that of the lower attachment member 16b. However, the curtain wall 10 of this embodiment adopts an attachment / detachment method in which the functional member 20 is moved downward together with the attachment member 16b, as described later. Therefore, the upper attachment member 16a may be formed partly or entirely integrally with the upper frame 15a and the auxiliary attachment member 17a, that is, the attachment member 16a does not have to be configured to be detachable.

[0053] Next, the effects of the curtain wall 10 of this embodiment will be described.

[0054] As described above, the attachment member 16b is detachably supported at least by the lower frame 15b, and can be easily pulled down toward the vision unit 12. The lower edge of the functional member 20 is connected to the attachment member 16b. For example, the functional member 20, which is a solar cell, may become defective due to aging or the like, and maintenance such as replacement may be required.

[0055] When performing such maintenance work on the curtain wall 10 of this embodiment, a worker pulls out the attachment member 16b downward from the vision section 12 side. Then, as shown in FIG. 5, the functional member 20 is also pulled out to the vision section 12 side together with the attachment member 16b. This allows the worker to easily untie the wiring 66, 67 at the connection section 68 and remove the functional member 20 from the attachment member 16b. In other words, the curtain wall 10 allows the functional member 20, which is installed in the sealed space between the glass 18 and the fireproof board 22 in the spandrel section 11, to be easily pulled out to the vision section 12 side for maintenance. This improves the workability of the maintenance work on the functional member 20 of the curtain wall 10.

[0056] Therefore, when performing maintenance on the functional members 20, the curtain wall 10 does not require large-scale work such as removing or destroying the fireproof boards 22 and the fireproof material 30 or removing the glass 18. In other words, when performing maintenance on the curtain wall 10, it is not necessary to set up scaffolding or the like on the exterior side, and it is possible to prevent the curtain wall 10 from losing its function as an exterior wall during maintenance, and to prevent the inside of the spandrel portion 11 from being exposed to wind and rain. In other words, according to the curtain wall 10 of this embodiment, various members for the purpose of improving the design of the building, shielding or shading can be incorporated into the spandrel portion 11, such as functional members 20 that are desired to be attached / detached or replaced in the long term, or functional members 20 that are desired to be installed while being protected from wind and rain, for example, not limited to solar cell power generation materials.

[0057] In the curtain wall 10 of this embodiment, the functional member 20 can be connected to the attachment member 16b via the lower holding frame 54b that holds the lower edge of the functional member 20. In this way, even if it is difficult to install the connecting portion between the functional member 20 and the attachment member 16b, the functional member 20 can be reliably supported by the support member 41.

[0058] Furthermore, the holding frames 54a, 54c, 54d which hold the upper edge and the left and right side edges of the functional member 20 are only engaged with the protruding pieces 46c, 59 which protrude from the visible surfaces of the upper frame 15a and the upright 28, and are therefore movable vertically relative to the upper frame 15a and the upright 28. As a result, when the functional member 20 moves downward, the protruding pieces 59 of the upright 28 in particular function as guide rails which guide the side edges (vertical holding frames 54c, 54d) of the functional member 20 in the vertical direction. This makes the downward movement of the functional member 20 even smoother.

[0059] The installation work of the functional member 20 on the spandrel portion 11 can be easily performed by reversing the procedure of the above-mentioned removal work. For example, the replaced functional member 20 is connected to the attachment member 16b via the retaining frame 54, and the wiring 66, 67 is connected at the wiring portion 68. Then, the attachment member 16b is moved upward and attached between the lower frame 15b and the auxiliary attachment member 17b, and the screws 60, 61 are fastened. In this way, the installation work of the functional member 20 is easy for the curtain wall 10. In other words, the curtain wall 10 can be manufactured in a factory as the second unit 11B to which the functional member 20 is attached in the same manner as the fireproof board 22, and the construction site only requires connecting the wiring 66, 67 to this, which reduces the construction work.

[0060] In the curtain wall 10 of this embodiment, the second frame 15 has a upright 28 as a vertical frame. The upper and lower frames 15a, 15b are supported by the upright 28 via brackets 31. This allows the curtain wall 10 to be efficiently constructed using a construction method in which units 11A, 11B assembled in a factory are connected to the upright 28 fixed to the building's framework, a so-called semi-unit construction method. The curtain wall 10 can also be used in a construction method in which the frames 14, 15 are assembled at the construction site to the upright 28 fixed to the building's framework, a so-called knock-down construction method, and is highly versatile.

[0061] Next, a curtain wall 10A according to a second embodiment will be described with reference to FIGS.

[0062] In the curtain wall 10A of the second embodiment, elements that have the same or similar functions and effects as the curtain wall 10 of the first embodiment described above are given the same reference symbols and detailed descriptions are omitted, and the same applies to the curtain walls 10B to 10D of the following embodiments.

[0063] As shown in Figures 6 and 7, the curtain wall 10A of the second embodiment is different from the curtain wall 10 of the first embodiment in that the upper attachment member 16a, not the lower attachment member 16b, is supported detachably and relatively movable with respect to the upper frame 15a and the auxiliary attachment member 17a. Therefore, the second unit 11B of this embodiment can be said to have a three-part structure in which the cross member constituting at least the upper part of the spandrel portion 11 has the upper frame 15a, the attachment member 16a, and the auxiliary attachment member 17a. The attachment member 16a may be supported only by the upper frame 15a.

[0064] In the curtain wall 10A as well, the upper attachment member 16a, upper frame 15a, and auxiliary attachment member 17a have a vertically symmetrical structure to the lower attachment member 16b, lower frame 15b, and auxiliary attachment member 17b.

[0065] That is, the attachment member 16a of this embodiment has a tapered or trapezoidal cross-sectional shape that tapers from top to bottom. The bent pieces 46d, 46d of the attachment member 16a are fixed to the upper surface of the auxiliary attachment member 17a and the upper surface of the bent piece 32d on the outside of the upper frame 15a using screws 60, 61. Furthermore, the attachment member 16a of this embodiment has a pair of engagement pieces 46e, 46f and a pair of wiring holes 46g, 46g, similar to the attachment member 16b described above. The engagement piece 46e can be engaged and disengaged from the engagement piece 62 of the auxiliary attachment member 17a from above. The engagement piece 46f can be engaged and disengaged from the engagement piece 32f of the upper frame 15a from above. Each wiring hole 46g penetrates the attachment member 16a from top to bottom and communicates with the wiring hole 32g formed on the inside of the upper frame 15a. The cover member 63 is placed directly above the attachment member 16a, and covers the upper frame 15a, the attachment member 16a and the auxiliary attachment member 17a.

[0066] 6, in this embodiment, wiring 66 is passed through attachment member 16a. Wiring 67 is passed between blind box 37 and fireproof board 22 and upper frame 15a. Wire connection portion 68 is disposed on the upper portion of upper frame 15a and attachment member 16a.

[0067] In the functional member 20 of this embodiment, the upper holding frame 54a of the holding frame 54 is fastened to the protruding piece 46c of the attachment member 16a by using a screw 58. Meanwhile, the holding frames 54b to 54d which hold the lower edge and the left and right side edges of the functional member 20 are only engaged with the protruding pieces 46c, 59 protruding from the visible surface of the bottom frame 15b and the upright 28, and are movable up and down relative to the bottom frame 15b and the upright 28.

[0068] In this embodiment, the lower attachment member 16b may be formed integrally with the lower frame 15b and the auxiliary attachment member 17b in part or in whole, that is, the attachment member 16b does not have to be configured to be detachable.

[0069] As described above, the attachment member 16a of this embodiment is detachably connected to at least the upper frame 15a, and can be easily pulled up toward the vision section 12 (see FIG. 7). The functional member 20 has its upper edge connected to the attachment member 16a. For this reason, when performing maintenance work such as replacing the functional member 20 in the curtain wall 10A of this embodiment, a worker pulls the attachment member 16a upward from the vision section 12 side. Then, as shown in FIG. 7, the functional member 20 is also pulled out toward the vision section 12 together with the attachment member 16a. For this reason, in the curtain wall 10A of this embodiment, maintenance of the functional member 20 can be easily performed, as in the curtain wall 10 of the first embodiment.

[0070] Next, a curtain wall 10B according to a third embodiment will be described with reference to FIGS.

[0071] As shown in Figures 8 to 11, the curtain wall 10B of the third embodiment differs from the curtain wall 10 of the first embodiment described above in that the functional member 20 is directly connected to the attachment member 16b without using a retaining frame 54.

[0072] In the curtain wall 10B, the functional member 20 has its lower edge directly fixed to the protruding piece 46c of the attachment member 16b by a screw 58. However, the functional member 20 in this embodiment is, for example, a thin film-like or sheet-like power generating material. For this reason, if only the lower edge of the functional member 20 is supported, it will wobble or bend, making it difficult to stably support itself within the spandrel portion 11. Therefore, the functional member 20 may be supported and held by an auxiliary member 70. The auxiliary member 70 is, for example, a surface material having sufficient rigidity, such as a resin panel. The auxiliary member 70 is preferably disposed on the indoor side surface opposite to the glass 18 side that receives sunlight. The auxiliary member 70 is, for example, placed on substantially the entire indoor side surface of the functional member 20, and is fixed integrally with the functional member 20 by a fixing member such as a screw, a double-sided adhesive tape, or an adhesive. The auxiliary member 70 is also fixed integrally to the attachment member 16b together with the lower edge of the functional member 20 by using a screw 58 (see FIG. 9).

[0073] In this embodiment, the upper edge and the left and right side edges of the functional member 20 and the auxiliary member 70 may be positioned and held in the projection direction by a guide member 72 connected to the projection surface of the attachment member 16a and the upright 28. The guide member 72 is an extruded shape of metal, such as aluminum. The guide member 72 is screwed to the projection surface of the attachment member 16a and the upright 28. The guide member 72 is formed in a substantially U-shaped cross section, and the edges of the functional member 20 and the auxiliary member 70 are inserted into an opening groove facing the inside of the frame to hold them. Reference numeral 73 in Figs. 9 and 10 denotes an auxiliary member that is screwed to the upper surface of the attachment member 16b and introduces the wiring 66 connected to the functional member 20 into the wiring hole 46g and positions and protects the wiring 66.

[0074] Therefore, as shown in Figs. 9 and 11, in the curtain wall 10B of this embodiment, the functional member 20 can be easily maintained by pulling down the attachment member 16b toward the vision section 12, as in the curtain wall 10 of the first embodiment. In particular, the curtain wall 10B does not have a retaining frame 54, as compared with the above-mentioned curtain wall 10, and therefore the configuration of the functional member 20 and its surroundings is further simplified. That is, in the curtain wall 10B, for example, the replacement work of the functional member 20 can be performed by simply attaching and detaching the functional member 20 to and from the auxiliary member 70 and the protruding piece 46c, and the work is further simplified. Also in the curtain wall 10B, the guide member 72 of the mullion 28 functions as a guide rail that guides the downward movement of the left and right side edges of the functional member 20 and the auxiliary member 70. This makes the downward movement of the functional member 20 even smoother.

[0075] This configuration in which the functional member 20 is held by the auxiliary member 70 and the guide member 72 without using the holding frame 54 may be applied to the curtain wall 10A of the second embodiment shown in Figures 6 and 7. In this case, the upper edge of the functional member 20 may be directly fixed to the protruding piece 46c of the attachment member 16a with the screw 58. Also, the lower edge of the functional member 20 may be positioned and held by fixing the guide member 72 to the visible surface of the attachment member 16b.

[0076] Next, a curtain wall 10C according to a fourth embodiment will be described with reference to FIG.

[0077] As shown in FIG. 12, a curtain wall 10C according to the fourth embodiment differs from the curtain wall 10 according to the above-described first embodiment in that reinforcing members 80-83 are provided.

[0078] The curtain wall 10C of this embodiment has a fireproof structure. In the curtain wall 10C, the fireproof material 30 provided at the connection between the fireproof board 22 and the second frame body 15 and around the connection, and the fireproof material 30 provided in the inner space of the attachment members 16a, 16b are thicker than the curtain wall 10 described above. In the curtain wall 10C, the brackets 32e of the upper frame 15a and the lower frame 15b are formed in a flat plate shape, so that the fireproof board 22 is also thicker. In the curtain wall 10C, the glass 50a on the outdoor side of the vision section 12 is made of mesh glass.

[0079] Furthermore, in the curtain wall 10C, reinforcing members 80, 81 are attached to the hollow portions of the upper frame 14a and the lower frame 14b of the first frame body 14. In the curtain wall 10C, reinforcing members 82, 83 are also attached to the inside of the auxiliary attachment members 17a, 17b. The reinforcing members 80-83 are members made by bending a metal such as steel or stainless steel sheet metal having a higher strength than the frames 14a, 14b and the auxiliary attachment members 17a, 17b, which are formed of extruded metal including aluminum. The reinforcing members 80, 81 are formed, for example, with a substantially U-shaped cross section. The reinforcing members 82, 83 are formed, for example, with a substantially crank-shaped cross section.

[0080] Therefore, as shown in Fig. 12, in the curtain wall 10C of this embodiment, the functional member 20 can be easily maintained by pulling down the attachment member 16b toward the vision section 12 side, as in the curtain wall 10 of the first embodiment. In addition, in the curtain wall 10C of this embodiment, the frames 14a, 14b and the auxiliary attachment members 17a, 17b are reinforced by the reinforcing members 80-83 described above. This allows a fireproof structure to be constructed on the outdoor side of the frames 15a, 15b and the attachment members 16a, 16b, in which the fireproof structure is constructed by the fireproof material 30 and the fireproof board 22. The reinforcing members 80-83 may be applied to the curtain walls 10A, 10B described above.

[0081] Next, a curtain wall 10D according to a fifth embodiment will be described with reference to FIGS.

[0082] As shown in Figures 13 to 15, the curtain wall 10D of the fourth embodiment differs from the curtain wall 10 of the first embodiment described above in that the functional member 20 is supported on the inside of the first frame body 14, rather than between the attachment members 16a, 16b.

[0083] In the curtain wall 10D, the functional member 20 has its four peripheral edges inserted into and held in the opening grooves of the guide members 72. It is preferable that the interior surface of the functional member 20 is held by the auxiliary members 70. The top, bottom, left, and right guide members 72 are screwed to the visible surface of the first frame body 14, and are installed in a frame shape as a whole. The functional member 20 and the auxiliary member 70 have their four peripheral edges held by the guide members 72, and are supported by the visible surfaces of the frames 14a-14d via the guide members 72.

[0084] In the curtain wall 10D of this embodiment, the upper and lower attachment members 16a, 16b can be supported so as to be detachable from the frames 15a, 15b and the auxiliary attachment members 17a, 17b and to be movable relative to each other in the vertical direction. The wiring 66, 67 passes through the space between the functional member 20 and the fireproof board 22 from the upper edge of the functional member 20, for example, and passes through the wiring hole 46g to the upper attachment member 16a.

[0085] Therefore, as shown in Fig. 15, when performing maintenance work such as replacing the functional member 20 in the curtain wall 10D of this embodiment, a worker pulls up the upper attachment member 16a from the vision section 12 side. Then, an opening 84 is formed between the auxiliary attachment member 17a and the upper frame 15a by the amount of the attachment member 16a removed. The worker inserts his hand or a predetermined tool into the spandrel section 11 from this opening 84, and removes the functional member 20 (and auxiliary member 70) from the four surrounding guide members 72 while, for example, elastically bending it. Then, the functional member 20 can be pulled out through the opening 84 to the vision section 12 side.

[0086] As a result, in the curtain wall 10D of this embodiment as well, maintenance of the functional members 20 can be easily performed, similarly to the curtain walls 10 of the above-mentioned embodiments, etc. In addition, the curtain wall 10D of this embodiment has the advantage that the functional members 20 can be disposed outside closer to the glass 18 within the spandrel portion 11, thereby improving the efficiency of receiving sunlight.

[0087] In the curtain wall 10D of this embodiment, not only the upper attachment member 16a but also the lower attachment member 16b may be removed during the above-mentioned maintenance work. In this case, an opening is formed between the lower auxiliary attachment member 17b and the lower frame 15b by removing the attachment member 16b, that is, an opening that is vertically symmetrical with the opening 84. Thus, the worker can insert his / her hand or tool into the spandrel portion 11 through the opening on the lower side of the spandrel portion 11, making the maintenance work of the functional member 20 even smoother. Of course, in the curtain wall 10D, the wiring 66, 67 may be passed through the lower attachment member 16b.

[0088] As described above, the curtain wall or sash according to one aspect of the present invention is a curtain wall or sash having a first opening facing the living space of a building and a second opening facing the boundary between upper and lower floors of the building, the second opening being provided with a first frame body having a first upper frame and a first lower frame and supporting glass, a second frame body arranged on the interior side of the first frame body and having a second upper frame and a second lower frame, a functional member arranged on the interior side of the glass, and an attachment member provided between the first frame body and the second frame body and detachably supported by at least one of the second upper frame and the second lower frame, thereby being movable in the vertical direction. According to this configuration, when performing maintenance work such as replacing the functional member, a worker can easily access the functional member by removing the attachment member from the upper frame or the lower frame from the first opening side. This improves the workability of the maintenance work of the functional member.

[0089] The second frame may be supported by a fireproof board, and the functional member may be disposed between the glass and the fireproof board. In this case, the functional member is disposed in an enclosed space between the glass and the fireproof board, and the functional member can be easily maintained by moving the attachment member.

[0090] The functional member may be supported by the attachment member, so that an operator can easily pull out the functional member toward the first opening by simply removing the attachment member from the first opening, further improving the efficiency of maintenance work on the functional member.

[0091] The first frame may be provided with a pair of uprights extending in the up-down direction on the indoor side, and both ends of the second upper frame and the second lower frame in the longitudinal direction may be supported by brackets provided on the visible surfaces of the pair of uprights. This allows for a construction method in which the upper and lower frames are attached to uprights fixed to the building framework, enabling efficient construction of curtain walls or sashes.

[0092] The first opening may be configured to include a third upper frame arranged vertically adjacent to the first lower frame, a third lower frame arranged vertically adjacent to the first upper frame, a third frame body supporting glass, and an auxiliary attachment member connecting at least one of the first upper frame and the third lower frame and the first lower frame and the third upper frame, and supporting the attachment member in a detachable manner. In this way, the second frame body supporting the attachment member on at least one of the upper frame and the lower frame can be smoothly connected to the first frame body.

[0093] The functional member may be connected to a wiring, and the wiring may pass through a first wiring hole formed in the attachment member and a second wiring hole formed in the interior wall of the second upper frame or the second lower frame. This simplifies the processing of the wiring connected to the functional member, and facilitates connection to the power source of the building on the interior side.

[0094] The functional member may be a power generating material, in which case the space of the second opening can be utilized to generate electricity, for example, by a solar cell.

[0095] A guide rail for guiding the vertical movement of the functional member may be provided, which makes the movement of the functional member even smoother.

[0096] The attachment member may be detachably supported by the second lower frame and movable toward the first opening, so that the functional member can be moved from the second opening to the first opening. In this way, the functional member can be easily pulled down from the ceiling side of the first opening.

[0097] The attachment member may be detachably supported by the second upper frame and movable toward the first opening, so that the functional member can be moved from the second opening to the first opening. In this way, the functional member can be easily pulled up from the floor side of the first opening.

[0098] The functional member may be supported by the first frame, which allows the functional member to be disposed even closer to the exterior side of the room.

[0099] It should be noted that the present invention is not limited to the above-described embodiment, and can of course be freely modified without departing from the spirit and scope of the present invention. [Explanation of symbols]
