Summary of the Invention

Problems to be Solved by the Invention

[0004] In order to enhance the water-stopping performance, the above-described conventional heat-insulating window sash has a step provided between the indoor side and the outdoor side, and airtight materials are provided on the indoor side and the outdoor side of the step, respectively. Therefore, a wide width of the mating surface of the frame body and the frame must be ensured. Further, since the step is provided at a position aligned in the in-plane direction of the glass, if a wide width of the mating surface of the frame body and the frame is ensured, the size of the glass has to be reduced. Even if the frame body and the frame made of an aluminum alloy have a configuration including a heat-insulating material, they have lower heat-insulating properties than glass. Therefore, there is a problem that the heat-insulating performance deteriorates when the width of the mating surface of the frame body and the frame is widened to enhance the water-stopping performance. <​​​ [Means for solving the problem]

[0006] The main invention for achieving this objective is an insulated building fixture characterized by comprising: a frame body in which a frame-side insulating material is interposed between an outdoor metal frame positioned on the outdoor side and an indoor metal frame positioned on the indoor side to form an opening; a hinged sliding door provided on the frame body so as to be able to open and close the opening; an airtight material provided between the hinged sliding door and the frame body in the in-plane direction of the hinged sliding door and positioned on the indoor side of the frame-side insulating material; and a partition member arranged in the depth direction of the airtight material and provided on the outdoor side of the frame-side insulating material to separate the indoor side from the outdoor side. Other features of the present invention will be made clearer by description in this specification and the accompanying drawings. [Effects of the Invention]

[Figure 3] This is a cross-sectional view of the insulated building fitting according to this embodiment. [Figure 4] This is an enlarged view of section A in Figure 2. [Figure 5] This is an enlarged view of section B in Figure 2. [Figure 6] This is an enlarged view of section C in Figure 3. [Modes for carrying out the invention]

[0009] The following describes an insulated building component according to one embodiment of the present invention with reference to the drawings. As an example of the insulated joinery 1 according to this embodiment, we will describe an example of insulated joinery 1 having a frame 10 fixed to the building structure and forming an opening 1a, and a hinged sliding door 20 attached to the frame 10 via a hinge 1b so as to be able to open and close, as shown in Figures 1 to 3.

[0010] The insulated joinery 1 has a hinge 1b on the right side when viewed from the inside, and the opening 1a of the sliding screen (hereinafter simply referred to as the screen) 20 is opened by pushing the handle 1c on the left side outwards. In the following description, when the insulated joinery 1 is installed in a building, etc., and viewed from the inside, the up and down direction is referred to as the up and down direction, the left and right direction as the left and right direction, and the depth direction, which is the direction between indoors and outdoors, as the depth direction. Furthermore, in the depth direction, the side that moves when the screen 20 opens is referred to as the outdoor side, and the opposite side as the indoor side. In addition, the side of the frame 10 that is the opening 1a is referred to as the inner circumference side, and the side of the frame 10 opposite to the opening 1a is referred to as the outer circumference side.

[0011] The shoji screen 20 is framed with an upper frame 21, a lower frame 24, and left and right vertical frames 27 to form a rectangular shape, and double-glazed glass 4 is installed inside. The double-glazed glass 4 consists of wired glass 4a, which is placed on the outdoor side, and Low-E glass 4b, which is placed on the indoor side, which are placed facing each other with a gap in the depth direction and installed as a single unit.

[0012] The upper frame 21, lower frame 24, and vertical frame 27 each have outer frame sections 22, 25, and 28 arranged on the outer perimeter side, and inner frame sections 23, 26, and 29 arranged on the inner perimeter side, and are connected via synthetic resin shoji-side insulation materials 6a, 6b, and 6c to form a single unit. Here, the outer frame sections 22, 25, and 28 correspond to the outdoor frame joined via the shoji-side insulation material, and the inner frame sections 23, 26, and 29 correspond to the indoor frame joined via the shoji-side insulation material. The outer frame sections 22, 25, and 28 and the inner frame sections 23, 26, and 29 are all extruded aluminum profiles with the longitudinal direction being the extrusion direction.

[0013] As shown in Figure 4, the outer periphery upper frame 22, which forms the outer periphery of the upper frame 21, has an upper frame facing surface portion 22a that forms a facing surface that faces the upper surface of the double-glazed glass 4, an upper frame downward extension portion 22b that extends downward from the indoor end of the upper frame facing surface portion 22a on the indoor side of the double-glazed glass 4, an upper frame inward extension portion 22c that extends inward from the lower end of the upper frame downward extension portion 22b, an upper frame upward extension portion 22d that extends upward from the indoor end of the upper frame facing surface portion 22a, and an upper batten locking portion 22e provided at the outdoor end of the upper frame facing surface portion 22a to which the batten 21a is locked. On the upper surface of the upper frame depth surface portion 22a, a synthetic resin upper frame airtight material 5a is provided along its entire length in an airtight material fitting portion 22f, which is provided along the longitudinal direction, approximately in the center in the depth direction.

[0014] Below the inward extension portion 22c of the upper frame, sash-side insulation material (hereinafter also referred to as upper frame insulation material) 6a is provided at the outdoor end and the indoor end, respectively, and an inner perimeter upper frame 23, which forms the inner perimeter frame of the upper frame 21, is provided so as to connect the lower ends of the two upper frame insulation materials 6a. The inner perimeter upper frame 23 has a flat underside that spans the two upper frame insulation materials 6a. Furthermore, the inner perimeter upper frame 23, which is connected by the inward extension portion 22c of the upper frame and the two upper frame insulation materials 6a, forms a hollow portion 21b that penetrates in the longitudinal direction on its inner side.

[0015] The upper end of the double-glazed glass 4 is held in place by a backup material 20a and a sealing material 20b, which are provided between the outdoor surface and the trim 21a that is locked to the upper trim locking portion 22e, and between the indoor surface and the outdoor end of the inner perimeter upper frame 23 and the upper frame insulation material 6a, respectively. As shown in Figure 5, the lower frame 24 has almost the same shape as the upper frame 21, but is positioned with its orientation reversed.

[0016] The outer lower frame 25 forming the outer peripheral frame of the lower frame 24 includes a lower frame prospective surface portion 25a that forms a prospective surface facing the lower surface of the double-pane glass 4, a lower frame upward extension portion 25b that extends upward on the indoor side of the double-pane glass 4 from the indoor-side end of the lower frame prospective surface portion 25a, a lower frame inward extension portion 25c that extends inward from the upper end of the lower frame upward extension portion 25b, and a lower pressing edge locking portion 25d provided at the outdoor-side end of the lower frame prospective surface portion 25a to which the pressing edge 24b is locked. On the lower surface of the lower frame prospective surface portion 25a, a lower frame airtight material fitting portion 25e provided along the longitudinal direction is provided substantially at the center in the prospective direction, and a synthetic resin lower frame airtight material 5b is provided over the entire length thereof.

[0017] On the lower frame inward extension portion 25c, shoji-side heat insulating materials (hereinafter also referred to as lower frame heat insulating materials) 6b are provided at the outdoor-side end and the indoor-side end, respectively, and an inner peripheral lower frame 26 forming the inner peripheral frame of the lower frame 24 is provided so as to connect the upper ends of the two lower frame heat insulating materials 6b. The upper surface of the inner peripheral lower frame 26 extends in a plane across the two lower frame heat insulating materials 6b. Further, the inner peripheral lower frame 26 connected by the lower frame inward extension portion 25c and the two lower frame heat insulating materials 6b forms a hollow portion 24a penetrating in the longitudinal direction inside thereof.

[0018] The double-pane glass 4 is placed on a setting block, and the lower end portion of the double-pane glass 4 is held by backup materials 20a and sealing materials 20b provided between the outdoor-side surface and the pressing edge 24b locked to the lower pressing edge locking portion 25d, and between the indoor-side surface and the outdoor-side end of the inner peripheral lower frame 26 and the lower frame heat insulating materials 6b, respectively.

[0019] The left and right vertical frames 27 are the same members and are arranged with their left and right directions reversed. Here, the configuration of the vertical frame 27 will be described by taking the right vertical frame as an example. As shown in FIG. 6, an outer peripheral vertical frame 28 forming the outer peripheral frame of the vertical frame 27 has a vertical frame projected surface portion 28a forming a projected surface facing the side surface of the multilayer glass 4, a vertical frame inward extension portion 28b extending in the inner peripheral direction on the indoor side of the multilayer glass 4 from the indoor-side end of the vertical frame projected surface portion 28a, a vertical frame indoor extension portion 28c extending indoors from the inner peripheral-side end of the vertical frame inward extension portion 28b, and a vertical pressing edge locking portion 28d provided at the outdoor-side end of the vertical frame projected surface portion 28a to which the pressing edge 27b is locked.

[0020] On the outer peripheral surface of the vertical frame projected surface portion 28a, a vertical central airtight material 5c made of synthetic resin is provided over the entire length in a vertical airtight material central fitting portion 28e provided along the longitudinal direction substantially at the center in the projected direction, and a vertical inner airtight material 5d made of synthetic resin is provided over the entire length in a vertical airtight material indoor fitting portion 28f provided along the longitudinal direction at the indoor-side end in the projected direction. That is, the vertical central airtight material 5c and the vertical inner airtight material 5d are provided at intervals in the projected direction.

[0021] On the inner peripheral side of the vertical frame indoor extension portion 28c, a shoji-side heat insulating material (hereinafter also referred to as a vertical frame heat insulating material) 6c is provided at each of the outdoor-side end and the indoor-side end, and an inner peripheral vertical frame 29 forming the inner peripheral frame of the vertical frame 27 is provided so as to connect the inner peripheral-side ends of the two vertical frame heat insulating materials 6c. The inner peripheral vertical frame 29 has a flat inner peripheral surface over the two vertical frame heat insulating materials 6c. Further, the inner peripheral vertical frame 29 connected by the vertical frame indoor extension portion 28c and the two vertical frame heat insulating materials 6c forms a hollow portion 27a penetrating in the longitudinal direction inside thereof.

[0022] The side end portion of the multilayer glass 4 is held by a backup material 20a and a sealing material 20b provided between the outdoor-side surface and the pressing edge 27b locked to the vertical pressing edge locking portion 28d, and between the indoor-side surface and the outdoor-side end of the inner peripheral vertical frame 29 and the vertical frame heat insulating material 6c, respectively.

[0023] As shown in Figures 2 and 3, the frame 10 is rectangular in shape, with an upper frame 11, a lower frame 14, and left and right vertical frames 17, and the inside of it forms an opening 1a. The upper frame 11, lower frame 14, and vertical frames 17 each have aluminum outdoor metal frames 12, 15, and 18 that are placed on the outdoor side and aluminum indoor metal frames 13, 16, and 19 that are placed on the indoor side, and are connected to form a single unit via synthetic resin frame-side insulation materials 6d, 6e, and 6f. The outdoor metal frames 12, 15, and 18 and the indoor metal frames 13, 16, and 19 are all extruded profiles with the longitudinal direction being the extrusion direction.

[0024] As shown in Figure 4, the upper frame 11 has an upper frame facing surface portion 11a that faces the upper frame facing surface portion 22a of the shoji screen 20 with a vertical gap between them and forms a facing surface, an upper frame downward extension portion 11b that extends downward from the indoor end of the upper frame facing surface portion 11a on the indoor side of the upper frame downward extension portion 22b, an upper frame inward extension portion 11c that extends inward from the lower end of the upper frame downward extension portion 11b, and an upper frame indoor facing surface portion 11d that extends downward from the indoor side of the upper frame inward extension portion 11c and forms a facing surface.

[0025] The upper frame facing surface 11a is equipped with frame-side insulation material (hereinafter also referred to as upper frame insulation material) 6d, and the upper frame insulation material 6d forms the outdoor upper frame 12, which is the outdoor metal frame of the upper frame 11 on the outdoor side. Furthermore, the portion of the upper frame facing surface 11a that is on the indoor side of the upper frame insulation material 6d is integrally formed with the upper frame downward extension portion 11b, the upper frame inward extension portion 11c, and the upper frame indoor facing surface portion 11d, forming the indoor upper frame 13, which is the indoor metal frame of the upper frame 11.

[0026] On the outdoor side of the lower extension portion 11b of the upper frame, a synthetic resin upper frame airtight material 5e is provided, protruding outwards and extending along its entire length. When the shoji screen 20 is closed, the upper frame airtight material 5e abuts against and presses against the upper extension portion 22d of the upper frame of the shoji screen 20. Therefore, when the shoji screen 20 is closed, the indoor side of the gap Sa between the upper frame depth surface portion 22a and the upper frame depth surface portion 11a, which is open on the outdoor side and connected in a nearly straight line in the depth direction, is closed by the upper frame airtight material 5e. In this gap Sa between the upper frame depth surface portion 22a and the upper frame depth surface portion 11a, the upper frame airtight material 5a and the upper frame airtight material 5e, which are provided near the boundary between the outdoor upper frame 12 and the upper frame insulation material 6d, are arranged side by side with a gap between them in the depth direction.

[0027] Furthermore, the upper end of the upper frame airtight material 5a, which is provided on the upper frame depth surface 22a, is positioned close enough not to come into contact with the upper frame depth surface 11a so as not to become a load when the shoji screen 20 is opened and closed, and the gap Sa is partitioned from the outdoor side to the indoor side by the upper frame airtight material 5a. In other words, the upper frame airtight material 5a is provided to partition the gap Sa above the upper frame depth surface 22a from the outdoor side to the indoor side in the depth direction, and corresponds to a partition member.

[0028] The upper frame inward extension portion 11c is positioned with a vertical gap between it and the upper frame inward extension portion 22c, and a hinge 1b is provided near the right end between the upper frame inward extension portion 11c and the upper frame inward extension portion 22c. The upper side of the upper frame inward extension portion 11c is covered by the building structure (not shown).

[0029] The upper frame interior facing surface 11d has a hollow section 11e that penetrates in the longitudinal direction and has a rectangular cross-section. The upper interior wall section 11f that forms the hollow section 11e in the upper frame interior facing surface 11d forms the upper interior facing surface together with the interior end of the upper frame inward extension section 11c. The lower end of the upper exterior wall section 11g that forms the hollow section 11e in the upper frame interior facing surface 11d extends downward and protrudes to the outside, and an interior upper airtight material 5f made of synthetic resin is provided along the entire length in the longitudinal direction. When the shoji screen 20 is closed, the interior upper airtight material 5f abuts against and is pressed against the interior end of the inner upper frame 23 of the shoji screen 20.

[0030] Furthermore, the upper frame airtight material 5e, the indoor upper airtight material 5f, and the upper frame insulation material 6d create a space Sc between the upper frame airtight material 5e and the indoor upper airtight material 5f in the upper frame 11, with a gap between it and the upper frame 21. This enhances the insulation performance along with the upper frame structure above the inward extension portion 11c and the hollow portion 11e of the indoor visible surface portion 11d of the upper frame. The indoor upper airtight material 5f is located on the indoor side of the upper frame airtight material 5e in the upper part of the insulated joinery 1, sealing the gap between the frame and the sliding door, and is a different airtight material from the upper frame airtight material 5e.

[0031] As shown in Figure 5, the lower frame 14 has a lower frame facing surface portion 14a that faces the lower frame facing surface portion 25a of the shoji screen 20 with a gap in the vertical direction and forms a facing surface, and a lower frame indoor facing surface portion 14b that extends upward from the indoor end of the lower frame facing surface portion 14a on the indoor side of the shoji screen 20.

[0032] The lower frame recessed surface 14a is equipped with a frame-side insulation material (hereinafter also referred to as lower frame insulation material) 6e in the portion facing the lower frame recessed surface 25a, and the portion on the outdoor side of the lower frame insulation material 6e forms the outdoor lower frame 15, which is the outdoor metal frame of the lower frame 14. Furthermore, the portion of the lower frame recessed surface 14a that is on the indoor side of the lower frame insulation material 6e is formed integrally with the indoor visible surface 14b of the lower frame, forming the indoor lower frame 16, which is the indoor metal frame of the lower frame 14.

[0033] The portion of the lower frame depth surface 14a that extends inward from the lower frame depth surface 25a is spaced vertically apart from the lower frame inward extension 25c, and a hinge 1b is provided near the right end between the lower frame depth surface 14a and the lower frame inward extension 25c.

[0034] The lower frame's indoor visible surface portion 14b has a hollow portion 14c that penetrates in the longitudinal direction and has a rectangular cross-section. The lower indoor wall portion 14d that forms the hollow portion 14c in the lower frame's indoor visible surface portion 14b forms the lower indoor visible surface together with the indoor end of the lower frame's recessed surface portion 14a. At the upper end of the lower outdoor wall portion 14e that forms the hollow portion 14c in the lower frame's indoor visible surface portion 14b, an indoor lower airtight material 5g made of synthetic resin is provided along the entire length in the longitudinal direction, protruding outwards. When the shoji screen 20 is closed, the indoor lower airtight material 5g abuts against and is pressed against the indoor end of the inner lower frame 26 of the shoji screen 20.

[0035] As shown in Figure 6, the vertical frame 17 has a vertical frame facing surface portion 17a that faces the vertical frame facing surface portion 28a of the shoji screen 20 with a gap in the left-right direction and forms a facing surface, and a vertical frame indoor facing surface portion 17b that extends inward from the indoor end of the vertical frame facing surface portion 17a on the indoor side of the shoji screen 20.

[0036] The vertical frame recess 17a is equipped with a frame-side insulation material (hereinafter also referred to as vertical frame insulation material) 6f in the portion facing the vertical frame recess 28a, and the portion on the outdoor side of the vertical frame insulation material 6f forms the outdoor vertical frame 18, which constitutes the outdoor metal frame of the vertical frame 17. Furthermore, the portion of the vertical frame recess 17a on the indoor side of the vertical frame insulation material 6f is formed integrally with the indoor visible surface 17b of the vertical frame, and forms the indoor vertical frame 19, which constitutes the indoor metal frame of the vertical frame 17.

[0037] The vertical frame interior facing surface 17b has a hollow section 17c that penetrates in the longitudinal direction and has a rectangular cross-section. The vertical interior wall section 17d that forms the hollow section 17c in the vertical frame interior facing surface 17b forms the vertical interior facing surface together with the interior end of the vertical frame depth surface 17a. The inner circumferential end of the vertical exterior wall section 17e that forms the hollow section 17c in the vertical frame interior facing surface 17b extends inward and protrudes outward, and an interior vertical airtight material 5h is provided along the entire length in the longitudinal direction. When the shoji screen 20 is closed, the interior vertical airtight material 5h abuts against and is pressed against the interior end of the inner vertical frame 29 of the shoji screen 20. The outer periphery of the interior vertical frame 19 is covered by the building structure (not shown).

[0038] The vertical interior airtight material 5d, the indoor vertical airtight material 5h, and the vertical frame insulation material 6c create a space Sd between the vertical interior airtight material 5d and the indoor vertical airtight material 5h in the vertical frame 17, and together with the outer frame structure of the indoor vertical frame 19 and the hollow portion 17c of the indoor visible surface portion 17b of the vertical frame, the insulation performance is enhanced. The indoor vertical airtight material 5h is provided on the side of the insulated door 1, on the indoor side of the vertical interior airtight material 5d, to seal the gap between the frame and the sliding door, and corresponds to an airtight material different from the vertical interior airtight material 5d.

[0039] When the shoji screen 20 is closed, a gap Sb is formed between the vertical frame depth surface 28a and the vertical frame depth surface 17a, with the outdoor side open and the gap Sb being formed in a nearly straight line in the depth direction, and this gap Sb is sealed by the vertical interior airtight material 5d. In this gap Sb between the vertical frame depth surface 28a and the vertical frame depth surface 17a, the vertical central airtight material 5c, which is provided near the boundary between the outdoor vertical frame 18 and the vertical frame insulation material 6f, and the vertical interior airtight material 5d, which is in contact with the indoor side of the vertical frame insulation material 6f, are arranged side by side with a gap in the depth direction. Furthermore, the inner edge of the vertical central airtight material 5c provided on the vertical frame depth surface 28a is positioned close enough not to come into contact with the vertical frame depth surface 17a so as not to become a load when opening and closing the shoji screen 20, and the gap Sb is partitioned between the outdoor side and the indoor side by the vertical central airtight material 5c. The vertical central airtight material 5c is provided to partition the void Sb on the outer periphery side of the vertical frame's recessed surface portion 28a into an outdoor side and an indoor side in the depth direction, and thus corresponds to a partition member.

[0040] According to the insulated joinery 1 of this embodiment, in the upper part of the insulated joinery 1, when the shoji screen 20 is closed, an upper frame airtight material 5a and an upper frame airtight material 5e are provided between the upper frame recessed surface 22a and the upper frame recessed surface 11a in the in-plane direction of the shoji screen 20. Therefore, the two airtight materials 5a and 5e, which are aligned in the depth direction, make it possible to prevent water from entering the interior from the exterior.

[0041] Furthermore, since the upper frame airtight material 5a and the upper frame airtight material 5e are arranged side by side in the depth direction, the gap Sa between the two airtight materials 5a and 5e can be provided in a straight line in the depth direction, eliminating the need for bending. As a result, the width of the space in the visible direction where the two airtight materials 5a and 5e are arranged can be narrowed, and the visible width of the outer perimeter part of the insulated joinery 1 can be narrowed compared to the double-glazed glass 4, thus enabling higher insulation performance.

[0042] Furthermore, when the shoji screen 20 is closed, the gap Sa that extends from the outside to the upper frame airtight material 5e, between the upper frame recessed surface 22a and the upper frame recessed surface 11a in the in-plane direction of the shoji screen 20, is partitioned into an indoor side and an outdoor side by the upper frame airtight material 5a. As a result, outside air has difficulty entering the indoor side, and the indoor space partitioned by the upper frame airtight material 5a becomes an insulated space, thus further improving the insulation performance.

[0043] Furthermore, since an indoor upper airtight material 5f is provided further indoors than the two airtight materials 5a and 5e, to seal the gap between the indoor visible surface portion 11d of the upper frame and the inner perimeter upper frame 23, it is possible to achieve even better watertightness.

[0044] Furthermore, since the indoor upper airtight material 5f is installed on the indoor side of the upper frame insulation material 6a, it is possible to more reliably prevent the outer perimeter upper frame 22 from being exposed on the indoor side of the indoor upper airtight material 5f. As a result, it is possible to provide an insulated building component 1 with superior thermal insulation and watertightness.

[0045] Furthermore, on the side of the insulated door 1, when the shoji screen 20 is closed, a vertical central airtight material 5c and a vertical inner airtight material 5d are provided between the vertical frame recess surface 28a and the vertical frame recess surface 17a in the in-plane direction of the shoji screen 20. Thus, the two airtight materials 5c and 5d, aligned in the depth direction, make it possible to prevent water from entering the interior from the exterior.

[0046] Furthermore, since the vertical central airtight material 5c and the vertical inner airtight material 5d are arranged side by side in the depth direction, the gap Sb between the two airtight materials 5c and 5d can be provided in a straight line in the depth direction, eliminating the need for bending. As a result, the width of the space in the visible direction where the two airtight materials 5c and 5d are arranged can be narrowed, and the visible width of the outer perimeter portion of the insulated joinery 1 can be narrowed compared to the double-glazed glass 4, thus enabling higher insulation performance.

[0047] Furthermore, when the shoji screen 20 is closed, the gap Sb, which is provided between the vertical frame recess 28a and the vertical frame recess 17a in the in-plane direction of the shoji screen 20 and extends from the outside to the vertical interior airtight material 5d, is partitioned into an indoor side and an outdoor side by the vertical central airtight material 5c. As a result, outside air has difficulty entering the indoor side, and the indoor space partitioned by the vertical central airtight material 5c becomes an insulated space, thus further improving the insulation performance.

[0048] Furthermore, since an indoor vertical airtight material 5h is provided further inside than the two airtight materials 5c and 5d to seal the gap between the indoor visible surface portion 17b of the vertical frame and the inner perimeter vertical frame 29, it is possible to achieve even better watertightness.

[0049] Furthermore, since the indoor vertical airtight material 5h is installed on the indoor side of the vertical frame insulation material 6c, it is possible to more reliably prevent the outer vertical frame 28 from being exposed on the indoor side of the indoor vertical airtight material 5h. As a result, it is possible to provide an insulated building component 1 with superior thermal insulation and watertightness.

[0050] Thus, in a rectangular insulated building component 1, by providing two airtight seals 5c and 5d in the gap Sb between the vertical frame 17 and the vertical stile 27 on the longer side, and further providing an airtight seal 5h on the indoor side, it becomes possible to achieve watertightness and heat insulation more efficiently.

[0051] The above embodiments are provided to facilitate understanding of the present invention and are not intended to limit its interpretation. The present invention can be modified and improved without departing from its spirit, and it goes without saying that the present invention includes equivalents thereof. This embodiment includes at least the following inventions.

[0052] The insulated building fixture is characterized by comprising: a frame body having an opening formed by interposing a frame-side insulation material between an outdoor metal frame positioned on the outdoor side and an indoor metal frame positioned on the indoor side; a hinged sliding door provided on the frame body so as to be able to open and close the opening; an airtight material provided between the hinged sliding door and the frame body in the in-plane direction of the hinged sliding door and positioned on the indoor side of the frame-side insulation material; and a partition member positioned parallel to the airtight material in the depth direction and provided on the outdoor side of the frame-side insulation material, separating the indoor side from the outdoor side.

[0053] With this type of insulated joinery, an airtight material and a partition member that separates the indoor and outdoor sides are provided between the sliding door and the frame in the in-plane direction of the sliding door. Therefore, the partition member and the airtight material prevent water from entering the indoor side from the outdoor side. Furthermore, since the airtight material and the partition member are arranged side by side in the depth direction, the gap between the airtight material and the partition member can be provided linearly in the depth direction, eliminating the need for bending. As a result, the width of the space in the visible direction where the airtight material and the partition member are arranged can be narrowed, and the visible width of the outer perimeter part of the insulated joinery can be narrowed compared to the sliding door, thus enabling higher insulation performance.

[0054] The insulated joinery is characterized in that, on the indoor side of the airtight material, another airtight material different from the airtight material is provided to seal the gap between the frame and the sliding door.

[0055] With this type of insulated joinery, another airtight seal is provided on the indoor side of the airtight seal to seal the gap between the frame and the sliding door. Therefore, even if water penetrates the indoor side of the airtight seal, it will be stopped by the other airtight seal on the outdoor side. This makes it possible to achieve superior watertightness.

[0056] The insulated joinery is characterized in that the sliding shoji screen comprises an outdoor frame and an indoor frame joined via a shoji screen-side insulation material, and the other airtight material is provided on the indoor side of the shoji screen insulation material.

[0057] With this type of insulated joinery, other airtight materials are installed on the interior side of the shoji screen insulation, making it possible to more reliably prevent the exterior frame from being exposed on the interior side of the other airtight materials. Therefore, it is possible to provide insulated joinery with superior thermal insulation and watertightness.

[0058] The insulated joinery is characterized in that the frame and the sliding door are rectangular in shape, and the airtight material and the partition material are provided between the frame and the sliding door on at least the longitudinal side of the rectangular shape.

[0059] With this type of insulated joinery, the airtight material and partition material are provided between the rectangular frame and the sliding door, at least on the longer side, making it possible to achieve watertightness and heat insulation more efficiently. [Explanation of Symbols]
