[0003] [Patent Document 1] Jpn. Jpn. Published No. 56-35464 Summary of the Invention [Problem to be solved by the invention]

[0004] When a cleaning gondola is hung from the roof of a high-rise or super-high-rise building to the floor with the surface material to be cleaned, the gondola passes over the outside of the floors along the way. The upper floors may be used as residences, and the gondola passes up and down over the outside of the windows of the residences. For the residents of the residences, it is unpleasant to have the gondola pass up and down over the outside of the windows of the residences in this way.

[0005] The present disclosure aims to provide a curtain wall that can be cleaned without having to suspend a cleaning gondola from the roof of a high-rise building or a super high-rise building. [Means for solving the problem]

[0006] The present disclosure relates to a curtain wall that is installed in a high-rise building or a super high-rise building and is composed of a plurality of panel materials, at least one of the panel materials being composed of an openable and closable door body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, the embodiment of the present disclosure will be described in detail with reference to the drawings. In this specification, the "visible direction" means the surface direction of the glass panel 35 in the fully closed state of the top-hung sliding door 1 that constitutes the door body housed in the lower sight rail 71 and the lower sight rail 72 of the opening 10 formed in the curtain wall of a high-rise building or a skyscraper B as a building, and the "visible direction" means the thickness direction (i.e., the depth direction) of the glass panel 35. The "visible direction" is also the indoor / outdoor direction. The "visible surface" means each surface of the sliding door 1 facing the outdoor side and the indoor side, and the "visible surface" means the surface of the sliding door 1 that extends in the indoor / outdoor direction. In the drawings, the outdoor side of the sliding door 1 is the outdoor side X1, and the side of the sliding door 1 closer to the indoor side is the indoor side X2.

[0009] More specifically, the sliding door 1 is a sliding door having a symmetrical paper screen 4, and is installed in a curtain wall 100 that constitutes the outer wall between the lower and upper floors of a high-rise building or a super-high-rise building B, which is a building with residential buildings on the upper floors and offices on the lower floors. Here, the term "high-rise building" means a building with a height of more than 31 meters, and the term "super-high-rise building" means a building with a height of more than 60 meters. In addition, the term "mid-rise building" means a building with 3 to 5 floors. As shown in FIG. 1, in an opening 10 in a part of the curtain wall 100 where a glass panel 35 as a surface material of the curtain wall 100 is not provided, the sliding door 1 supported by an upper sight rail 61 and an upper sight rail 62 (see FIG. 5, etc.) that constitute the door body movement support part is installed so as to close the opening 10, and constitutes a part of the curtain wall 100. This makes it possible to take out a gondola (not shown) for cleaning glass panels 35 suspended by a crane to the outside X1 from an opening 10 on a floor intermediate between the lower and upper floors of high-rise building or skyscraper B. Therefore, when cleaning glass panels 35 of high-rise building or skyscraper B, it becomes possible to clean glass panels 35 on middle and lower floors without the gondola passing over the outside X1 of the residences on the upper floors.

[0010] As shown in Figures 2 and 3, the sliding door 1 is a sliding door that comprises a frame body 2 that is attached to an opening 10 (see Figure 1), a screen 4 that can move in the front and back directions from the frame body 2, and a door body movement support part (upper sight rail 61, upper sight rail 62) (see Figure 2, etc.) that suppresses the vibration of the screen 4 and guides the movement of the screen 4.

[0011] The frame body 2 has an upper frame 21 and a lower frame 22 as interlocking members, and left and right vertical frames 23, 23 as uprights, and is framed in a rectangular shape by the upper frame 21 and the vertical frames 23, 23.

[0012] The shoji screen 4 comprises a frame 40 and a glass panel 35 fitted inside the frame 40. The frame 40 is constructed by assembling an upper frame 41, a lower frame 42, a door end frame 43, and a door end frame 44, each of which is made of an aluminum alloy, and a middle frame 45 is provided to span the center of the door end frame 43 and the door end frame 44 in the vertical direction.

[0013] As shown in Figures 5 and 8, a support body 5 is provided on the indoor side X2 of the frame 40. The support body 5 is formed by assembling into a rectangle an upper support body 51 arranged on the indoor side X2 of the upper frame 41 in a positional relationship parallel to the upper frame 41, a lower support body 52 arranged on the indoor side X2 of the lower frame 42 in a positional relationship parallel to the lower frame 42, and a pair of vertical support bodies 53 arranged on the indoor sides X2 of the front and rear frames 43 and 44 in a positional relationship parallel to the front and rear frames 43 and 44, respectively, all of which are made of aluminum alloy.

[0014] As shown in Fig. 8, a central support 54 is provided at the center of the support 5 in the left-right direction in the visual direction so as to bridge the center of the upper support 51 (see Fig. 5) and the center of the lower support 52 in the same direction. The central support 54 is made of an aluminum alloy, and a rotating shaft 542 is provided adjacent to the central support 54 and in parallel therewith.

[0015] The rotating shaft portion 542 is made of stainless steel, and penetrates the upper support 51 and the lower support 52 in the vertical direction. As shown in Fig. 9 and other figures, a pinion (not shown) stored in a storage portion 5422 and a roller 5421 are provided at the lower end of the rotating shaft portion 542 so as to be coaxially rotatable together with the rotating shaft portion 542. Similarly, as shown in Fig. 5, a pinion (not shown) stored in a storage portion 5423 is provided at the upper end of the rotating shaft portion 542 so as to be coaxially rotatable together with the rotating shaft portion 542.

[0016] 8, a reducer 541 is fixed to the central support 54. A handle 5412 for inputting manual power is rotatably supported by a housing 5411 of the reducer 541 in the reducer 541. A speed reducer (not shown) for reducing the rotational speed of the rotational force of the handle 5412 is accommodated in the housing 5411. The rotational speed of the rotational force of the handle 5412 is reduced and transmitted to the rotating shaft 542, causing the rotating shaft 542 to rotate.

[0017] As shown in Fig. 5 etc., the pair of vertical supports 53 are fixed to the ends of the inside X2 of the plate-shaped support arms 531 extending in the projection direction. The ends of the outside X1 of the pair of support arms 531 are fixed to the door end frame 43 and the door end frame 44, respectively. The support arms 531 are each made of an aluminum alloy and are provided at a predetermined interval in the vertical direction, whereby the support 5 supports the shoji 4. In the following explanation, since the shoji 4 and support 5 of the sliding door 1 that opens and closes the opening 10 are configured symmetrically, the shoji 4 and support 5 located on the left side when viewed from the outside X1 to the inside X2 will be explained, and the shoji 4 and support 5 located on the right side will be omitted.

[0018] 4, the upper frame 21 is configured by arranging an upper frame upper part 211 and an upper frame lower part 212 in this order from above, and an upper frame outer part 213 is arranged on the outdoor side of the upper frame lower part 212. An outer rain barrier gasket 2131 that curves downward on the outdoor side X1 is provided on the underside of the outdoor side end part of the lower side of the upper frame outer part 213.

[0019] The outer rain barrier gasket 2131 comes into contact with the edge 412 of the upper frame 41 when the screen 4 moves to the outside X1 as described below and reaches the outermost position in X1, i.e., when the opening 10 is closed by the screen 4. This makes it possible to prevent rainwater, etc. from the outside X1 from entering the inside X2 from between the upper frame exterior 213 and the edge 412 of the upper frame 41. A rain barrier gasket 2121 that hangs down downward is provided below the lower side of the upper frame lower part 212. A rain barrier gasket (not shown) is also provided in the lower frame 22 in a similar manner.

[0020] A through hole through which the lock pin 5311 passes is formed in the upper end portion of the room side X2 of the vertical frame 23 on the door end side connected to the upper frame 21, and a lock pin engagement portion 231 with which the lock pin 5311 engages is fixedly provided. Similarly, lock pin engagement portions 231 (see FIG. 8, etc.) with which the lock pin 5311 engages are fixed to the center and lower end portions of the vertical frame 23 in the up-down direction.

[0021] The upper frame 41 has an upper frame body 411. A flange 412 is provided at the end of the upper frame body 411 on the outside side X1, and the flange 412 supports the outside side X1 of the glass panel 35 via a gasket 413. A glazing seal 414 and a glass spacer gasket 415 are arranged in this order from above on the end face of the outside side X1 of the upper frame body 411, and support the inside side X2 of the glass panel 35 via these.

[0022] The glass panel 35 is a heat reflective laminated glass formed by bonding two identical rectangular glass plates together with an interlayer film 32 sandwiched therebetween. The glass panel 35 forming the sliding door 1 is a heat reflective laminated glass having the same shape, i.e., the same width and height in the visible direction and the same structure, as the glass panel 35 forming the curtain wall 100 without forming the sliding door 1. This allows the sliding door 1 to form part of the exterior of the curtain wall 100, and makes it possible to make the sliding door 1 less noticeable so that it is not immediately clear where the sliding door 1 is in the curtain wall 100, thereby improving the design.

[0023] The indoor side X2 portion of the upper frame body 411 has a U-shaped back panel support part 4111 that opens downward. The back panel support part 4111 supports the back panel 36, which is made of an aluminum composite laminate, and the spacer 37 by sandwiching them.

[0024] The end of the upper frame body 411 on the indoor side X2 has an upward extension 4113 that bends upward and extends. The part that bends upward is provided with an end sealant 4112, which is a block that fills the space at the bent corner. The upper part of the end sealant 4112 is formed one step lower on the indoor side X2, and an annular gasket 4114 is provided on this part. When the shoji screen 4 moves to the outdoor side X1 as described below and moves to the outermost position on the outdoor side X1 to close the opening 10 (see FIG. 1), the annular gasket 4114 abuts against the rear end surface of the upper frame lower part 212 as shown in FIG. 4, and provides a liquid-tight seal between the upper frame lower part 212 and the end sealant 4112.

[0025] Furthermore, a rain barrier gasket 4115 extending upward is provided in the center of the top surface of the upper frame body 411 in the projection direction. When the screen 4 moves toward the outside X1 and reaches the outermost X1 position to close the opening 10 (see FIG. 1), the rain barrier gasket 4115 comes into contact with the rain barrier gasket 2121 as shown in FIG. 4. This prevents rainwater and the like from the outside X1 from entering the inside X2 from between the upper frame lower part 212 and the upper frame 41.

[0026] A lock pin support part 532 that supports the lock pin 5311 so as to be vertically movable is provided at the upper end part of the end frame 44 that is connected to the upper frame 41. Lock pin support parts 532 that support the lock pin 5311 so as to be vertically movable are also provided at the lower end part and the central part in the vertical direction of the end frame 44.

[0027] A handle (not shown) provided on the end frame 44 is drivingly connected to each of the lock pins 5311 via a link (not shown), and the lock pins 5311 are configured to be moved up and down by moving the handle (not shown) up and down. The lock pin 5311 rises and engages with the lock pin engagement portion 231, so that even if the sliding door 1 is placed in a place where wind pressure is high, such as an intermediate floor between a lower floor and a higher floor of a high-rise building or a super high-rise building B, the sliding door 1 can withstand wind pressure and maintain a closed state.

[0028] Next, the details of the door body movement support part that opens and closes the sliding door will be described. The door body movement support part is equipped with an upper sight rail 61 and an upper sight rail 62 arranged in a lattice shape on the upper side of the sliding door 1 as shown in Fig. 5, etc., and a lower sight rail 71 and a lower sight rail 72 arranged in an L shape on the lower side of the sliding door 1 as shown in Fig. 8, etc.

[0029] 5, 6, etc., the upper side of the upper sight rail 61 is fixed to an H-beam H1 installed in a high-rise building or a super high-rise building B. As shown in Fig. 6, the upper sight rail 61 has a fixed part 611, a rail support upper part 612, a rail support lower part 613, and a rail part 614. The fixed part 611, the rail support upper part 612, and the rail support lower part 613 are made of stainless steel, and are provided in combination as a plurality of sets.

[0030] This combination is arranged in two rows in a direction perpendicular to the longitudinal direction of the H-steel H1 and fixed to multiple H-steel steels H1 arranged in parallel with their longitudinal directions oriented in the prospective direction, as shown in Fig. 5. Two rail portions 614 are provided in parallel and supported in each of the multiple combinations in a positional relationship in which their longitudinal directions are oriented in a direction perpendicular to the longitudinal direction of the H-steel steel H1, so as to straddle the multiple H-steel steels H1.

[0031] 6, the cross section of the fixed part 611 perpendicular to the longitudinal direction of the rail part 614 is formed in a C-shape that opens downward. The central part of the fixed part 611 in the horizontal direction is fixed to the H-beam H1 by a bolt.

[0032] 6, the rail support upper part 612 is disposed inside the fixed part 611, and a cross section perpendicular to the longitudinal direction of the rail part 614 is formed into a C-shape that opens downward. Both ends of the rail support upper part 612 in the horizontal direction are fixed to the inner surface of the fixed part 611 by bolts.

[0033] The rail support lower part 613 has a cross section perpendicular to the longitudinal direction of the rail part 614, which is formed into a pair of symmetrical crank shapes facing each other in the projection direction. The upper part of the rail support lower part 613 is fixed to the horizontal part of the rail support upper part 612 by bolts.

[0034] The rail portion 614 is made of steel material, and the cross section perpendicular to the longitudinal direction of the rail portion 614 is formed in a C-shape that opens downward, and is supported by being held by the middle and lower parts of the rail support lower portion 613. The longitudinal direction of the rail portion 614 is parallel to the front direction.

[0035] The openings at both ends in the longitudinal direction of the rail portion 614 are closed with bolts and nuts. When the wheels 621 described below deteriorate over time and need to be replaced, the bolts and nuts can be removed while the rail portion 625 is supported, the wheels 621 can be removed from the openings at both ends in the longitudinal direction of the rail portion 614, and new wheels 621 can be inserted through the openings, thereby replacing the wheels 621.

[0036] The upper projected rail 62 has a pair of wheels 621, a wheel support portion 622, a support plate material 623, a rail support portion 624, and a rail portion 625. As shown in FIG. 6, the pair of wheels 621 are arranged coaxially in two pairs in the longitudinal direction of the rail portion 614 to form one set, and are accommodated inside the C-shaped rail portion 614 so as to be able to run. The two pairs of wheels 621 arranged in two pairs to form one set are provided at a predetermined interval inside each of the two rail portions 614. Each of the wheels 621 is rotatably supported by the upper end portion of the wheel support portion 622.

[0037] The support plate material 623 is made of an aluminum alloy and is made of a pair of rectangular steel plates whose longitudinal direction is oriented in a direction perpendicular to the longitudinal direction of the rail portion 614. A wheel support portion 622 supporting a first pair of wheels 621 of one of the two rail portions 614 and a wheel support portion 622 supporting a first pair of wheels 621 of the other of the two rail portions 614 each penetrate one of the support plate materials 623. A wheel support portion 622 supporting a second pair of wheels 621 of one of the two rail portions 614 and a wheel support portion 622 supporting a second pair of wheels 621 of the other of the two rail portions 614 each penetrate the other of the support plate materials 623.

[0038] The upper parts of rail support parts 624 are fixed by bolts to the lower surface of support plate material 623. Rail support parts 624 are made of stainless steel, and are made of steel plates formed into a pair of crank-shaped symmetrical shapes facing each other in the projection direction in a cross section perpendicular to the longitudinal direction of rail part 625. Two pairs of rail support parts 624 are fixed to each of the pair of support plate materials 623, totaling four pairs.

[0039] The rail portion 625 has a cross section perpendicular to the longitudinal direction of the rail portion 625 formed in a C-shape that opens downward, and is supported by being held by the middle and lower parts of the rail support portion 624. The rail portion 625 is made of a steel material. The lower ends of the wheel support portions 622 are fixed to the upper portion of the rail portion 625 by bolts. As a result, the pair of rectangular support plate materials 623 and the pair of rail portions 625 are arranged in a parallel positional relationship in the up-down direction. The longitudinal direction of the rail portion 625 is parallel to the projection direction.

[0040] The openings at both ends in the longitudinal direction of the rail portion 625 are blocked with bolts and nuts. When the wheels 513 described below deteriorate over time and need to be replaced, the bolts and nuts can be removed while the screen 4 and the support body 5 are supported, the wheels 513 can be removed from the openings at both ends in the longitudinal direction of the rail portion 625, and new wheels 513 can be inserted through the openings, thereby replacing the wheels 513.

[0041] Wheels 513 are provided inside rail section 625. As shown in Fig. 7, wheels 513 are housed in a manner that a pair of coaxially arranged wheels 513 are arranged in two pairs in the longitudinal direction of rail section 625 to form one set, and are capable of running inside C-shaped rail section 625. Two sets of wheels 513 arranged in two pairs to form one set are provided at a predetermined interval inside each of two rail sections 625. Each set is rotatably supported by an upper end of wheel support section 512.

[0042] The lower end of the wheel support part 512 penetrates the upper part of the upper support body 51, which is composed of three rectangular steel members assembled into a U-shape that opens downward, and is fixed to the upper part of the upper support body 51. The wheels 513 run inside the rail part 625 and are guided by the rail part 625, so that the support body 5 and the shoji screen 4 fixed to the support body 5 via the support arm 531 can move forward and backward as a whole in the forward direction. In addition, the wheels 621 run inside the rail part 614 and are guided by the rail part 614, so that the rail part 625, the support body 5, and the shoji screen 4 can move forward and backward as a whole in the forward direction.

[0043] As shown in Fig. 9, the lower sight rail 71 includes an indoor sight direction sliding plate portion 711 and an outdoor sight direction sliding plate portion 712. The lower sight rail 72 includes a rack 721 and an outdoor sight direction sliding plate portion 722. The indoor sight direction sliding plate portion 711 and the outdoor sight direction sliding plate portion 712 are arranged at a predetermined interval and are arranged in a parallel positional relationship extending in the sight direction. Between the indoor sight direction sliding plate portion 711 and the outdoor sight direction sliding plate portion 712, a roller 5421 is guided by the indoor sight direction sliding plate portion 711 and the outdoor sight direction sliding plate portion 712 and can move in the sight direction.

[0044] The rack 721 and the prospective direction sliding plate portion 722 are disposed at a predetermined interval and are disposed in a parallel positional relationship extending in the prospective direction. A pinion (not shown) at the lower end of the rotating shaft portion 542 is screwed into the rack 721. The pinion (not shown) at the upper end of the rotating shaft portion 542 is screwed into a rack 627 (see FIG. 5) that is disposed between a pair of rail portions 625 in a positional relationship parallel to the pair of rail portions 625 and extends in the prospective direction.

[0045] When the opening 10 is closed by the pair of shoji screens 4, the handle 5412 is rotated to rotate the rotating shaft 542 together with the pinion (not shown). As a result, the wheel 621 moves inside the rail portion 614, and the support body 5 and shoji screen 4 move together toward the interior side X2 in the forward direction along the rack 721 and rack 627. At this time, the roller 5421 slides and is guided by the forward direction sliding plate portion 722.

[0046] When the support 5 and the shoji screen 4 move to the innermost position X2 in the projection direction, the roller 5421 comes into contact with the inner projection direction sliding plate portion 711. In this state, the worker manually pushes the support 5 and the shoji screen 4 in the projection direction in a direction that separates the pair of shoji screens 4 from each other (hereinafter referred to as the "outward projection direction"). As a result, the roller 5421 is inserted between the inner projection direction sliding plate portion 711 and the outer projection direction sliding plate portion 712.

[0047] Then, when the worker pushes the support body 5 and the screen 4 outward in the facing direction by hand, the rollers 5421 slide and are guided by the indoor facing direction sliding plate portion 711 and the outdoor facing direction sliding plate portion 712, and move outward in the facing direction, while the wheels 513 move inside the rail portion 6254. When the pair of screens 4 move to a position where they are furthest apart in the same direction, the opening 10 is fully opened.

[0048] At this time, a gondola (not shown) for cleaning the glass panel 35 can be moved out from the opening 10 to the outside X1 while being suspended by a crane. This, combined with the fact that the door body is a sliding door 1, makes it possible to move the gondola from the opening 10 to the outside X1 by using a crane by retracting the shoji screen 4 to a position where it does not obstruct the movement.

[0049] Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.

[0050] For example, in the present embodiment, the door body is configured as the sliding door 1, but is not limited to this. For example, the door body may be configured as a hinged door. This allows the structure for opening and closing the door body to be simplified.

[0051] In this embodiment, the pair of screens 4 move the screen 4 from the state where the opening 10 is closed to the inside X2 in the prospective direction, and when the screen 4 moves to the inside-most X2 in the prospective direction, the screen 4 is moved outward in the prospective direction to open it, but this is not limited to the above. It is sufficient that the door body constituting the sliding door can be moved in the prospective direction and can be opened and closed in the prospective direction at any position moved to the inside of the prospective direction.
