Description

[Technical Field]

[0001] The present invention relates to building materials. [Background technology]

[0002] When fittings are supported on the main body, sealing material is filled between the projected surface located on the outer periphery of the frame body and the inner periphery of the opening in the main body to prevent water from outside from entering the room (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Publication No. 7-1503 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the above-mentioned fittings, if there is a large gap between the visible surface of the frame and the inner peripheral surface of the skeleton, it becomes difficult to ensure watertightness. In particular, if a step is provided so that the indoor visible surface located on the indoor side of the frame material that makes up the frame is closer to the outer periphery than the outdoor visible surface located on the outdoor side, the gap between the outdoor visible surface and the inner peripheral surface of the skeleton cannot be reduced, and the above-mentioned problem becomes even more pronounced.

[0005] In view of the above-mentioned circumstances, the present invention aims to provide a fitting that can ensure watertightness even when there is a large gap between the frame body and the main body. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objective, the building fixture of the present invention is a building fixture in which a frame body is attached to a main body with a sealing material filled between the frame body and the inner surface of an opening provided in the main body, and is characterized in that an attachment is provided between the frame material that constitutes the frame body and the main body, the attachment is attached only to the frame material, and the sealing material is provided between the attachment and the main body. [Effects of the Invention]

[0007] According to the present invention, a seal member is provided between the attachment attached to the frame material and the main body, so watertightness can be ensured even when there is a large gap between the frame body and the main body. Moreover, because the attachment is attached only to the frame material, there is no concern that the work of removing the frame body from the main body during renovations, etc. will become complicated.

[0009] Preferred embodiments of the fittings according to the present invention will be described in detail below with reference to the accompanying drawings. Note that, for convenience, the terms "invisible direction" and "visible direction" will be used below. The "invisible direction" is the direction along the depth of the fittings, as indicated by arrow A in the drawings. A surface along the invisible direction will be referred to as a "visible face." The "visible direction" is the direction perpendicular to the invisible direction in the case of an object that extends horizontally, such as a sill. In the case of an object that extends vertically, such as a vertical frame, the "visible direction" is the horizontal direction perpendicular to the invisible direction. A surface along the invisible direction will be referred to as a "visible face."

[0010] 1 to 4 show a fitting according to an embodiment of the present invention. The fitting illustrated here is called a single-sliding window, and is comprised of a frame 10 and a fixed shoji screen 20 and a movable shoji screen 30 attached to the frame 10. In particular, in this embodiment, as shown in FIGS. 12 and 13, a fitting that can be attached to a wooden frame (hereinafter referred to as a wooden frame WB) is also used for a concrete frame (hereinafter referred to as a concrete frame CB). The frame 10 is constructed by assembling an upper frame (frame material) 11, a lower frame 12, and left and right vertical frames (frame materials) 13, 14 on all four sides. Inside the frame 10, a mullion 15 is arranged vertically between the upper frame 11 and the lower frame 12. The upper frame 11, the lower frame 12, and the left and right vertical frames 13, 14 that make up the frame 10 are constructed so that their dimensions along the projection direction are approximately the same. In contrast, the upright 15 is configured so that its dimensions along the front direction are smaller than those of the upper frame 11, and is attached at a position approximately equidistant from the left and right vertical frames 13, 14 in the outdoor parts of each of the upper frame 11 and lower frame 12.

[0011] The fixed shoji screen 20 is constructed by disposing a panel 21 of double-glazed glass or the like in the area surrounded by the upper frame 11, lower frame 12, one vertical frame 13, and mullion 15. In this embodiment, the fixed shoji screen 20 is provided between the vertical frame located on the right side when viewed from inside the room (hereinafter referred to as the right vertical frame 13 when distinguishing between them) and the mullion 15. The movable shoji screen 30 is constructed by attaching an upper frame 32, a lower frame 33, and left and right vertical frames 34, 35 to the four periphery of a rectangular panel 31 of double-glazed glass or the like, and is disposed in the frame body 10 on the inside of the room relative to the mullion 15 so as to be able to slide left and right along the left. When the movable shoji screen 30 is placed in the closed position relative to the frame body 10, the vertical frame 34 located on the right side as viewed from inside the room is arranged side by side in the forward direction relative to the upright 15, and the vertical frame 35 located on the left side as viewed from inside the room and the vertical frame located on the left side as viewed from inside the room (hereinafter referred to as the left vertical frame 14 when distinguishing between them) are abutted against each other via the tight material 1.

[0012] This fixture uses an upper frame 11, a lower frame 12, left and right vertical frames 13, 14, and a mullion 15, each of which has a wooden frame molding portion 11A, 12A, 13A, 14A, 15A on the interior side made of wood or wood-based material (hereinafter simply referred to as wood, etc.) and a metal frame molding portion 11B, 12B, 13B, 14B, 15B on the exterior side made of metal such as aluminum alloy. The upper frame 11, right vertical frame 13, and mullion 15 each have a wooden batten 2 made of wood or the like attached to the inner periphery of the wooden frame molding portion 11A, 13A, 15A, on the interior side. The upper edge and both left and right side edges of the panel 21 of the fixed shoji 20 are sandwiched between the wooden batten 2 of the wooden frame molding portion 11A, 13A, 15A and the metal frame molding portion 11B, 13B, 15B. The lower edge of the panel 21 is sandwiched between a metal flange 3 on the exterior side and a resin flange 4 on the interior side, both of which are attached to the metal frame molding portion 12B of the lower frame 12.

[0013] Similarly, the upper frame 32, lower frame 33, and left and right vertical frames 34, 35 each have a wooden frame molding portion 32A, 33A, 34A, 35A on the indoor side made of wood or the like, and a metal frame molding portion 32B, 33B, 34B, 35B on the outdoor side made of metal such as aluminum alloy. A wooden batten 5 made of wood or the like is attached to the inner periphery of the wooden frame molding portion 32A, 33A, 34A, 35A, which faces the indoor side. The panel 31 of the movable shoji screen 30 has its four edges sandwiched between the wooden batten 5 of the wooden frame molding portion 32A, 33A, 34A, 35A and the metal frame molding portion 32B, 33B, 34B, 35B.

[0014] As can be seen from Figure 4, the above-mentioned fittings are attached to an opening CBO in a concrete structure CB, consisting of an upper frame 11, a lower frame 12, and left and right vertical frames 13 and 14 that make up the frame 10. The opening CBO in the concrete structure CB is constructed by installing an ALC panel CBP between a concrete lower wall portion CB1 and an upper wall portion CB2. In this embodiment, the concrete lower wall portion CB1 forms the lower edge of the opening CBO, and the three ALC panels CBP form the upper and side edges of the opening CBO. A sponge-like member sp and a flat bar fb are installed at multiple locations along the length of the upper portion of the lower wall portion CB1. The sponge-like member sp has a rectangular cross section and is embedded in a portion approximately centered in the forward direction and a portion facing the interior of the room. The flat bar fb is a flat metal plate that covers the sponge-like member sp and is installed in the lower wall portion CB1 with its upper surface exposed. The lower frame 12 of the frame 10 described above is attached to the lower wall portion CB1 via a flat bar fb. The upper frame 11 and vertical frames 13, 14 of the frame 10 are attached to the ALC panel CBP with mounting brackets 17 interposed between each ALC panel CBP. Below, we will explain the respective configurations of the upper frame 11, left and right vertical frames 13, 14, and lower frame 12 of the frame 10 and their mounting structure to the concrete structure CB, and also provide a detailed description of the features of the present invention.

[0015] The wooden frame molding portion 11A of the upper frame 11 and the wooden frame molding portions 13A, 14A of the vertical frames 13, 14 are configured to have a substantially uniform cross-sectional shape over their entire longitudinal length. In this embodiment, as shown in Figures 5 to 8, the wooden frame molding portion 11A of the upper frame 11 and the wooden frame molding portions 13A, 14A of the vertical frames 13, 14 are configured to have a cross-sectional shape surrounded by six planes. That is, the wooden frame molding portion 11A of the upper frame 11 and the wooden frame molding portions 13A, 14A of the vertical frames 13, 14 each have a cross-sectional shape with an inner peripheral visible surface 41 on the inner periphery side, an interior facing surface 42 facing the interior of the room, a first outer peripheral visible surface (indoor facing surface) 43 on the outer periphery side, a first exterior facing surface 44 facing the exterior of the room, a second outer peripheral visible surface 45 on the outer periphery side, and a second exterior facing surface 46 facing the exterior of the room. The dimension of the inner peripheral projection surface 41 along the projection direction is approximately equal to the sum of the dimension of the first outer peripheral projection surface 43 along the projection direction and the dimension of the second outer peripheral projection surface 45 along the projection direction. An inner peripheral engagement groove 41a opening to the inner peripheral side is formed along the longitudinal direction on the edge of the inner peripheral projection surface 41 located on the exterior side of the room. The dimension of the interior projection surface 42 along the projection direction is approximately equal to the sum of the dimension of the first exterior projection surface 44 along the projection direction and the dimension of the second exterior projection surface 46 along the projection direction, and is smaller than the dimension of the inner peripheral projection surface 41 along the projection direction. The first outer peripheral projection surface 43 is provided on the interior side of the wooden frame molding portions 11A, 13A, and 14A, and its dimension along the projection direction is greater than half the dimension of the inner peripheral projection surface 41 along the projection direction. An outer peripheral engagement recess 43a opening to the outer peripheral side is formed along the longitudinal direction on the edge of the first outer peripheral projection surface 43 located on the exterior side of the room. The first exterior visible surface 44 is provided on the outer periphery, and its dimension along the visible direction is greater than half the dimension along the visible direction of the interior visible surface 42. A step 47 is provided so as to protrude from the inside corner formed by the second outer periphery visible surface 45 and the first exterior visible surface 44.

The dimension of the outer peripheral sight plate 51 along the sight direction is approximately equal to the dimension along the sight direction from the first outer peripheral sight surface 43 to the step 47 in the wooden frame molding portion 11A of the upper frame 11. The sight surface of the outer peripheral sight plate 51 facing the room is provided with a rib 51a that abuts against the first outside sight surface 44 of the wooden frame molding portion 11A. The outer peripheral engagement plate 52 extends from the outer peripheral edge of the outer peripheral sight plate 51 toward the interior of the room and then bends at a nearly right angle toward the inner peripheral side. The outer peripheral sight plate 53 extends almost horizontally from the inner peripheral edge of the outer peripheral sight plate 51 toward the exterior of the room and then tilts slightly inward toward the exterior. The dimension of the outer peripheral sight plate 53 along the projection direction is set larger than the dimension of the wooden frame molding 11A along the projection direction from the first exterior sight surface 44 to the second exterior sight surface 46. The extending edge of the outer peripheral sight plate 53 bends toward the inner peripheral side. The support leg plate 54 protrudes inward from the projection surface on the inner peripheral side of the outer peripheral sight plate 53. The dimension along the projection direction from the outer peripheral sight plate 51 to the support leg plate 54 is set smaller than the dimension along the projection direction from the first exterior sight surface 44 to the second exterior sight surface 46. The screw holes 55 protrude inward from a portion of the projection surface on the inner periphery of the outer peripheral projection plate 53 that is closer to the room than the support leg plate 54, and are generally cylindrical with an open inner periphery. The protruding dimension of the screw holes 55 from the outer peripheral projection plate 53 is approximately the same as that of the support leg plate 54. The inner peripheral sight plate 56 extends in the sight direction from a portion of the projection surface on the inner periphery of the outer peripheral projection plate 53 that is closer to the room than the support leg plate 54 toward the inner periphery. The dimension along the sight direction from the outer peripheral sight plate 51 to the inner peripheral sight plate 56 is set larger than the dimension along the sight direction from the first exterior sight surface 44 to the second exterior sight surface 46.The dimension in the sight direction from the outer peripheral sight plate portion 53 to the extending edge of the inner peripheral sight plate portion 56 is approximately equal to the dimension in the sight direction from the step portion 47 to the inner peripheral sight surface 41. The inner peripheral sight plate portion 57 extends in the sight direction from the inner peripheral edge of the inner peripheral sight plate portion 56 toward the interior of the room. The extending edge of the inner peripheral sight plate portion 57 is bent toward the outer peripheral side. The dimension from the bent edge of the inner peripheral sight plate portion 57 to the bent edge of the outer peripheral engagement plate portion 52 is approximately equal to the dimension in the sight direction from the outer peripheral engagement recess 43a to the inner peripheral engagement groove 41a. The sight cover fin portion 58 extends in the sight direction from the inner peripheral edge of the inner peripheral sight plate portion 56 toward the exterior of the room and then extends in the sight direction toward the inner peripheral side. The inward protruding plate portion 59 extends from the extending edge of the sight cover fin portion 58 toward the interior of the room. The extending edge of the inward protruding plate portion 59 is provided with a pocket portion 59a that opens toward the interior of the room.

[0017] The metal frame molding part 11B of the upper frame 11 is attached to the exterior side of the wooden frame molding part 11A by arranging the bent extension of the outer peripheral engagement plate part 52 in the outer peripheral engagement recess 43a and engaging the bent extension of the inner peripheral projection plate part 57 in the inner peripheral engagement groove 41a. In this state, the outer peripheral projection plate part 51 abuts against the first exterior projection surface 44 via the rib 51a, and the outer peripheral projection plate part 53 abuts against the second outer peripheral projection surface 45 via the support leg plate part 54. The outer peripheral projection plate part 51 provides an outer edge surface 11a facing the exterior between the first outer peripheral projection surface 43 of the wooden frame molding part 11A extending in the projection direction on the interior side and the outer peripheral projection plate part 53 of the metal frame molding part 11B extending in the projection direction on the exterior side. In the wooden frame molding portion 11A of the top frame 11, in the portion that is on the interior side of the room relative to the upright 15, an upper guide rail 11C is disposed along almost the entire length of the inner peripheral visible surface. This upper guide rail 11C guides the sliding of the movable shoji screen 30 in cooperation with a lower guide rail 72f provided on the bottom frame 12, which will be described later. As shown in Figure 2, in the wooden frame molding portion 11A of the top frame 11, in the portion located between the upright 15 and the right vertical frame 13, the above-mentioned wooden batten 2 is provided so as to protrude inward on the inner peripheral visible surface, and the upper edge of the panel 21 is sandwiched between this wooden batten 2 and an inward-protruding plate portion 59 provided on the metal frame molding portion 11B, via a timber material 6. In the portion of the wooden frame molding portion 11A located between the upright 15 and the left vertical frame 14, as shown in Figures 3, 5, and 6, a cover support member 11D is provided so as to protrude inward on the projected inner surface, and a cover member 11E is provided between this cover support member 11D and an inward protruding plate portion 59 provided on the metal frame molding portion 11B of the upper frame 11.

The outer periphery sight plate 61 extends along the sight direction. The dimension of the outer periphery sight plate 61 along the sight direction is approximately equal to the dimension of the wooden frame molding parts 13A and 14A along the sight direction from the first outer periphery sight surface 43 to the step 47. The sight surface of the outer periphery sight plate 61 facing the room is provided with a rib 61a that serves as an abutment for the first exterior sight surface 44 of the wooden frame molding parts 13A and 14A. The outer periphery engagement plate 62 extends from the edge located on the outer periphery of the outer periphery sight plate 61 toward the room and then bends toward the inner periphery at approximately a right angle. The outer peripheral sight plate 63 extends approximately horizontally in the projection direction from the inner peripheral edge of the outer peripheral sight plate 61 toward the outside of the room. The dimension of the outer peripheral sight plate 63 along the projection direction is configured to be larger than the dimension along the projection direction from the first exterior sight surface 44 to the second exterior sight surface 46 in the wooden frame molding sections 13A, 14A. The inner peripheral sight plate 64 extends in the projection direction from the inner peripheral surface of the outer peripheral sight plate 63 toward the inner peripheral side, and then curves toward the room.

The outer connecting plate portion 73b extends almost horizontally from the inner peripheral edge of the bridge material accommodating portion 73a toward the exterior of the room, and then extends toward the inner peripheral side in the find direction. The inner peripheral plate portion 73c extends almost horizontally from the inner peripheral edge of the outer connecting plate portion 73b toward the exterior of the room. This inner peripheral plate portion 73c is provided with an outer protruding piece 73j and an inner engaging piece 73k. The outer protruding piece 73j extends toward the interior from the extending edge of the inner peripheral plate portion 73c in the find direction. The inner engaging piece 73k protrudes toward the interior from the inner peripheral plate portion 73c, toward the find direction, on a side closer to the interior than the outer protruding piece 73j. The above-mentioned metal edge 3 is arranged to engage with this inner engaging piece 73k. The protruding dimension of the inner engagement piece 73k toward the inner periphery is set smaller than that of the outer protruding piece 73j. The outer plate portion 73d extends in the find direction from the portion of the inner periphery plate portion 73c located on the exterior side of the room toward the outer periphery. The extending dimension of the outer plate portion 73d is set so that it extends toward the outer periphery beyond the bridge material accommodating portion 73a. The inner connecting plate portion 73e is inclined from the visible surface located on the exterior side of the outer connecting plate portion 73b toward the exterior periphery. The extending dimension of the inner connecting plate portion 73e is approximately equal to the dimension along the find direction of the bridge material accommodating portion 73a. The support plate portion 73f extends approximately horizontally toward the exterior from the extending edge of the inner connecting plate portion 73e. The dimension from the front surface 12d of the wooden frame molding 12A facing the interior of the room to the edge of the support plate 73f located on the exterior side of the room is set smaller than the dimension along the front side of the lower wall portion CB1. The inner plate 73g extends from the extended edge of the support plate 73f at an angle toward the exterior of the room, and then extends toward the exterior side in the front side. The extending edge of the inner plate 73g is provided with an auxiliary plate 73m and screw holes 73n. The auxiliary plate 73m extends approximately horizontally from the inner plate 73g toward the interior of the room. The screw holes 73n are provided on the exterior-facing edge of the extending edge of the inner plate 73g. The front abutment plate 73h extends from the interior-facing edge of the auxiliary plate 73m toward the exterior side in the front side.The outer peripheral plate portion 73i protrudes from the screw hole 73n toward the outer periphery and then extends toward the outside of the room, and after connecting to the edge portion located on the outer periphery of the outer plate portion 73d, protrudes further toward the outside of the room. After extending toward the outer periphery, the extending edge portion of the outer peripheral plate portion 73i bends toward the inside of the room.

[0026] The interior section 72 and the exterior section 73 are connected by a bridge member 74 interposed between each bridge member housing 72a, 73a and the bridge member housing 71a of the middle section 71. As is clear from Figure 9, the inner surfaces of the bridge member housing 71a of the middle section 71, the bridge member housing 72a of the interior section 72, and the bridge member housing 73a of the exterior section 73, including the bridge member 74 interposed between them, are located on approximately the same horizontal plane. The resin ledge 4 described above is located on this flat portion. Similarly, the outermost portion of the middle section 71, the outermost surface of the outer peripheral engagement plate 72b of the interior section 72, the outermost portion of the bridge member housing 73a of the exterior section 73, and the outermost surface of the support plate 73f are located on approximately the same horizontal plane as the projected surface 12c of the outer periphery of the wooden frame molding section 12A.

[0027] As described above, the fittings of this embodiment are those that can be attached to a wooden skeleton WB and are also used for a concrete skeleton CB. Therefore, first, the case where the frame 10 is attached to the wooden skeleton WB will be explained. That is, Figures 12 and 13 show fittings attached to the wooden skeleton WB. An opening is formed in the wooden skeleton WB by providing a lintel WBM and a window sill WBW between the left and right columns WBP.

[0028] The top frame 11 and the left and right vertical frames 13, 14 are placed in the opening b2 with their respective outer edge surfaces 11a, 13a, 14a flush with the exterior surface b1 of the wooden skeleton WB. They can then be attached to the wooden skeleton WB by threading screws S1 from the respective wooden frame moldings 11A, 13A, 14A toward the wooden skeleton WB. Waterproof sheets WP are attached to the outer edge surface 11a of the top frame 11 and the outer edge surfaces 13a, 14a of the vertical frames 13, 14, respectively, extending from the exterior surface b1 of the wooden skeleton WB. Then, exterior wall materials EM are placed on the exterior side, facing the outer edge surfaces 11a, 13a, 14a of the top frame 11 and the vertical frames 13, 14, from the exterior surface b1 of the wooden skeleton WB. Sealant ES is then filled between the end faces of the exterior wall materials EM and the respective outer perimeter projection boards 53, 63.

[0029] The lower frame 12 is attached to the wooden frame WB by abutting the upper surface of the window sill WBW with the outer peripheral surface 12c of the wooden frame molding 12A, the outermost portion of the intermediate section 71 of the metal frame molding 12B, the outer peripheral surface of the outer peripheral engagement plate 72b of the indoor section 72, the outermost portion of the bridging material storage section 73a of the outdoor section 73, and the outer peripheral surface of the support plate 73f, and the outer peripheral surface of the outer peripheral abutment plate 73h against the outer surface of the wooden frame WB facing the outside. Then, the exterior wall material EM is placed on the outdoor side facing the outer surface b1 of the wooden frame WB, and a sealant ES is filled between the end face of the exterior wall material EM and the outer peripheral wall.

[0030] Here, in the above-mentioned upper frame 11 and left and right vertical frames 13, 14, the second outer periphery projection surface 45 is located on the inner periphery side relative to the first outer periphery projection surface 43, so when attached to the concrete structure CB, a large gap will be created between the second outer periphery projection surface 45 and the ALC panel CBP. Therefore, if a sealant is filled between the ALC panel CBP in this state, it will be difficult to ensure sufficient watertightness. For this reason, in this embodiment, when attached to the concrete structure CB, the reinforcing material 80 and the attachment 81 are provided at positions that overlap in the projection direction on the outer periphery side of the second outer periphery projection surface 45.

[0031] The reinforcement member 80 includes an attachment piece 80a, an inner reinforcement piece 80b, an exterior piece 80c, and an outer reinforcement piece 80d, which are integrally formed from steel. The attachment piece 80a is flat and sized to protrude beyond the outer edge surfaces 11a, 13a, and 14a when covering the outer engagement recess 43a. The inner reinforcement piece 80b is flat and extends in the visible direction from the outer edge of the attachment piece 80a toward the inner periphery. The extension length of the inner reinforcement piece 80b is set so that when the attachment piece 80a is abutted against the first outer periphery projection surface 43 of the wooden frame molding part 11A, 13A, or 14A, it can abut against or be close to the outer periphery projection plate parts 53 and 63. The exterior piece portion 80c has a flat plate shape extending in the front direction from the edge located on the inner periphery of the inner reinforcing piece portion 80b toward the outside of the room. The extending length of the exterior piece portion 80c is set shorter than the extending dimension of the outer periphery extending plate portions 53, 63. The outer reinforcing piece portion 80d has a flat plate shape extending in the front direction from the extending edge of the exterior piece portion 80c toward the outer periphery. The extending length of the outer reinforcing piece portion 80d is set shorter than the extending length of the inner reinforcing piece portion 80b.

[0032] The attachment 81 has a seal receiving piece portion 81a, an outer piece portion 81b, an inner seal receiving piece portion 81c, and a support piece portion 81d, and is integrally molded from a metal such as an aluminum alloy. The seal receiving piece portion 81a is flat. The dimension of the seal receiving piece portion 81a along the projection direction is set to be greater than the overall length of the reinforcing material 80 along the projection direction. The outer piece portion 81b extends from the edge of the seal receiving piece portion 81a located on the exterior side of the room toward the interior side. The extension length of the outer piece portion 81b is set to be approximately half the extension length of the inner reinforcing piece portion 80b. The inner seal receiving piece portion 81c extends from the edge of the outer piece portion 81b located on the interior side of the room toward the interior side. The extension length of the inner seal receiving piece portion 81c is approximately equal to the difference between the extension length of the seal receiving piece portion 81a and the total length of the reinforcing material 80 along the projection direction. The support piece portion 81d extends in the projection direction from the extending edge of the inner seal receiving piece portion 81c toward the inner side. The extension length of the support piece portion 81d is set to a dimension that allows it to abut against or come close to the outer peripheral projection plate portions 53, 63 when the seal receiving piece portion 81a is abutted against the first outer peripheral projection surface 43 of the wooden frame molding portions 11A, 13A, 14A via the mounting piece portion 80a of the reinforcing material 80.

[0033] As shown in Figures 6-8, the above-mentioned reinforcement material 80 and attachment 81 are attached to the upper frame 11 and the left and right vertical frames 13, 14 by screwing screw members S3 from the seal receiving piece 81a through the mounting piece 80a into the wooden frame molding parts 11A, 13A, 14A with the mounting piece 80a abutting against the inner surface of the seal receiving piece 81a and the outer reinforcing piece 80d abutting against the surface of the support piece 81d facing the room. In this case, the protrusion dimension of the outer piece 81b from the outer edge surfaces 11a, 13a, 14a toward the outside of the room is set to be approximately the same as the protrusion dimension of the outer peripheral projection board parts 53, 63. A sealant 82 is filled between the inner peripheral projection surface of the inner seal receiving piece 81c and the outer peripheral projection board parts 53, 63. Furthermore, the attachment 81 defines a hollow space between it and the upper frame 11 and between it and the left and right vertical frames 13, 14. For this reason, as shown in Figure 11, cover members 83 are attached to close the open end faces of the hollow spaces between the attachment 81 and the upper frame 11 and between the attachment 81 and the vertical frames 13, 14. The cover members 83 attached to the lower end faces of the vertical frames 13, 14 may be provided with drainage holes.

[0034] The top frame 11 and the left and right vertical frames 13, 14 with the attachment 81 attached as described above are attached to the ALC panel CBP by abutting the first outer peripheral projection surfaces 43 of the wooden frame moldings 11A, 13A, and 14A against the mounting brackets 17 provided on the ALC panel CBP via the liners 18. Then, screw members S4 are threaded into the mounting brackets 17 through the wooden frame moldings 11A, 13A, and 14A, thereby attaching the top frame 11 and the left and right vertical frames 13, 14 to the ALC panel CBP with reduced gaps between them. Therefore, by subsequently filling the gap between the ALC panel CBP and the seal receiving piece 81a of the attachment 81 with sealant 84, sufficient watertightness can be ensured between the concrete structure CB and the frame 10. Furthermore, because the cover member 83 is attached to the end of the attachment 81, there is no risk of the filled sealant 84 penetrating into the hollow space. Furthermore, the attachment 81 and the reinforcing member 80 are attached only to the top frame 11 and the vertical frames 13, 14. Therefore, when removing the frame body 10 from the concrete structure CB to renovate the fixture, the sealing material 84 can be cut away and the screw member S4 can be loosened, which is advantageous in terms of workability.

[0035] On the other hand, the dimension from the visible surface 12d of the wooden frame molding portion 11A facing the interior of the room to the edge of the support plate portion 73f located on the exterior side of the room is smaller than the dimension along the projection direction of the lower wall portion CB1, making it difficult to attach the lower frame 12 to the upper surface of the lower wall portion CB1 as is. For this reason, in this embodiment, a spacer 90 is arranged on the upper surface of the flat bar fb provided on the lower wall portion CB1.

[0036] The spacer 90 comprises an inner peripheral member 91 and an outer peripheral member 92. The inner peripheral member 91 is formed from steel metal and includes a frame support wall 91a and two inner peripheral guide walls 91b. The frame support wall 91a is flat. The dimension of the frame support wall 91a along the projection direction is approximately equal to the dimension from the visible surface 12d of the wooden frame molding 12A facing the interior of the room to the edge of the support plate 73f located on the exterior side. The inner peripheral guide wall 91b extends in the projection direction from the exterior and interior edges of the frame support wall 91a toward the periphery, approximately parallel to each other. The extension dimension of the inner peripheral guide wall 91b is set larger than the dimension from the visible surface of the support plate 73f facing the periphery to the extending edge of the projection abutment plate 73h. The outer peripheral member 92 is formed from steel metal and has a mounting wall 92a and two outer peripheral guide walls 92b. The mounting wall 92a is flat. The outer peripheral guide walls 92b extend in the find direction toward the inner periphery from the edge of the mounting wall 92a located on the outside and the edge located on the inside of the room, respectively, and are approximately parallel to each other. The extension dimension of the outer peripheral guide wall 92b is set smaller than that of the inner peripheral guide wall 91b. The dimension from the find surface of the outer peripheral guide wall 92b located on the outside of the room to the find surface of the outer peripheral guide wall 92b located on the inside of the room is approximately equal to the mutual spacing of the inner peripheral guide wall 91b.

[0037] The spacer 90 is secured to the lower wall portion CB1 by threading the screw members S5 into the flat bar fb and the sponge-like member sp via the installation surface 92c of the installation wall portion 92a. The outer guide wall portion 92b of the outer member 92 is then positioned between the inner guide wall portions 91b, and the screw members S6 are threaded into the outer guide wall portion 92b via the inner guide wall portion 91b to form the spacer 90. In this state, the spacer 90 is provided above the flat bar fb, and has a frame support surface 91c that can abut from the visible surface 12d of the wooden frame molding portion 12A facing the room to the edge of the support plate portion 73f located on the outside of the room. Therefore, the lower frame 12 can be attached to the concrete structure CB via the spacer 90 by threading the screw members S7 into the inner member 91 via the wooden frame molding portion 12A with the lower frame 12 abutting against the frame support surface 91c. A cover material 12C made of wood or the like is disposed on the inner peripheral portion of the wooden frame molding part 12A, into which the screw member S7 is screwed. A sealing material 93 is filled in the gap provided between the outer peripheral plate part 73i of the metal frame molding part 12B and the upper surface of the lower wall part CB1.

[0038] In this way, with the fixture of this embodiment, it is possible to attach the frame body 10 to the concrete skeleton CB without the need for welding work, which makes it possible to simplify the work of attaching the frame body 10. In particular, with the fixture of this embodiment, the frame body 10 that is attached to the wooden skeleton WB can also be used for the concrete skeleton CB, which is advantageous in terms of manufacturing costs due to the sharing of parts.

[0039] While the above-described embodiment illustrates a single-sliding window, the present invention can also be applied to other types of windows, such as double sliding windows, sliding projection windows, and fixed windows. Furthermore, the upper frame 11, lower frame 12, and vertical frames 13, 14 each include wood-frame molding portions 11A, 12A, 13A, 14A, and 15A, respectively, made of wood or the like, and metal-frame molding portions 11B, 12B, 13B, 14B, and 15B, respectively, which provides advantages in terms of thermal insulation. However, the present invention is not limited to this. For example, the present invention may also include portions molded from materials other than wood or metal, such as resin, or may be applied to windows with frames made of a single material. The shapes of the upper frame 11, lower frame 12, and vertical frames 13, 14 are not limited to those described in the embodiments. For example, the upper frame 11 and vertical frames 13, 14 do not necessarily have outer edge surfaces 11a, 13a, and 14a. Furthermore, the shape of the attachment 81 is not limited to that of the embodiment, and other shapes may be used as long as they reduce the gap between the skeleton CB and the frame 10, and there is no need to provide the reinforcing material 80. In this case, the skeleton does not need to be made of concrete, and may be made of wood.

[0040] Furthermore, in the above-described embodiment, the concrete structure CB on which the frame 10 is provided is exemplified as one having flat bars fb in the lower wall portion CB1, but the concrete structure does not necessarily have to have flat bars. Note that when flat bars fb and sponge-like members sp are provided on the concrete structure CB in the above-described embodiment, they are provided at multiple locations along the length, but the flat bars and sponge-like members may also be provided in a continuous line along the length.

[0041] As described above, the building fixture of the present invention is a building fixture in which a frame body is attached to a main body with a sealing material filled between the frame body and the inner surface of an opening in the main body, and is characterized in that an attachment is provided between the frame material that constitutes the frame body and the main body, the attachment is attached only to the frame material, and the sealing material is provided between the attachment and the main body. According to this invention, a seal member is provided between the attachment attached to the frame material and the main body, so watertightness can be ensured even when there is a large gap between the frame body and the main body. Moreover, because the attachment is attached only to the frame material, there is no concern that the work of removing the frame body from the main body during renovations, etc. will become complicated.

[0042] The present invention is also characterized in that, in the above-mentioned building fixture, the attachment has a flat plate-like outer periphery along the projection direction, and the sealing material is provided between the projection surface on the outer periphery and the inner periphery of the main body. According to this invention, since there are no irregularities on the outer periphery of the attachment, the work of removing the frame body from the main body can be facilitated.

[0043] The present invention is also characterized in that, in the above-mentioned building fixture, the frame material has an outer edge surface facing the outside between an indoor-side visible surface extending in the visible direction on the indoor side and an outdoor-side visible surface extending in the visible direction on the outdoor side, and is attached to the main body via the indoor-side visible surface, and the visible surface on the outer periphery of the attachment on which the sealing material is provided is positioned so as to overlap in the visible direction with the outdoor-side visible surface. According to this invention, the attachment can be made smaller.

[0044] The present invention is also characterized in that, in the above-mentioned building fixtures, the frame material has a wood frame molding portion formed from wood or wood material and a metal frame molding portion formed from metal, and the wood frame molding portion has the indoor side visible surface, and the metal frame molding portion has the outdoor side visible surface and the outer edge surface. According to this invention, weather resistance can be ensured by the metal frame molding portion, and heat insulation can be improved by the wood frame molding portion.

[0045] Furthermore, the present invention is characterized in that, in the above-mentioned fittings, the attachment has an inner seal receiving piece portion between which a sealing material is provided and the exterior visible surface. According to this invention, it is possible to prevent water from outside from entering the room through the gap between the attachment and the frame material.

[0046] The present invention is also characterized in that, in the above-mentioned building fixture, the attachment is arranged so as to form a hollow space between the attachment and the frame material, and a cover member is provided at the end of the attachment so as to cover the open end face of the hollow space. According to this invention, it is possible to increase the strength of the attachment while preventing foreign matter such as water from entering the hollow portion, and it is possible to more reliably ensure watertightness.

[0047] The present invention is also characterized in that in the above-mentioned fitting, a reinforcing material is provided between the attachment and the frame material. According to this invention, the strength of the attachment can be further increased. [Explanation of symbols]
