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

[0002] In fittings that take thermal insulation into consideration, shapes having a metal shape portion on the outside of the room and a resin shape portion on the inside of the room are sometimes used (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-324292 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above-mentioned fittings, the resin profile parts are exposed to the interior of the room, and therefore have many opportunities to come into contact with other objects, which may cause scratches.

[0005] In view of the above circumstances, the present invention aims to provide a fitting that can improve thermal insulation while preventing the problem of scratches on the shaped members. [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 constructed by arranging panels inside a shaped frame made up of a plurality of shaped members, and is characterized in that at least one of the shaped members has a metal shaped member on the outside of the room and a resin shaped member on the inside of the room, and the resin shaped member has a metal interior member on the part facing the inside of the room. [Effects of the Invention]

[0007] According to the present invention, the structure is constructed with a metal profile portion on the outdoor side and a plastic profile portion on the indoor side, which improves thermal insulation. Moreover, since the plastic profile portion is provided with a metal indoor member on the side facing the indoor side, there is no risk of the structure being damaged even if it comes into contact with other objects.

The resin frame portion 21B of the new upper frame 21 has a new upper inner frame body 21d that is tubular and has a substantially rectangular cross section. The dimension of the new upper inner frame body 21d along the projection direction is smaller than that of the new upper outer frame body 21a, but the dimension along the projection direction is approximately equal to that of the new upper outer frame body 21a. A new upper door stop wall 21e is provided at the corner located on the interior side of the new upper inner frame body 21d. The new upper door stop wall 21e protrudes inward from the new upper inner frame body 21d. A new inner support wall 21f is provided at the corner located on the interior side of the new upper inner frame body 21d on the exterior side. The new inner support wall 21f extends toward the interior side and then bends toward the interior side. A new upper engagement protrusion 21g is provided on the exterior side of the corner of the new upper inner frame body 21d located on the exterior side, and a new upper inner hook portion 21h is provided on the interior side. The new upper engagement protrusion 21g protrudes toward the exterior side and is provided to correspond to the new upper locking piece 21b of the metal frame portion 21A. The new upper inner hook portion 21h extends toward the outside of the room and then bends toward the inner periphery, and is provided to correspond to the new upper outer hook portion 21c of the metal frame portion 21A. Screw holes 21i are provided inside the hollow interior of the new upper outer frame body 21a.

[0016] The metal frame portion 21A and resin frame portion 21B of the new upper frame 21 are interconnected by engaging the new upper outer hook portion 21c and the new upper inner hook portion 21h with each other and engaging the new upper locking piece 21b with the new upper locking protrusion 21g. Furthermore, the metal frame portion 21A and resin frame portion 21B of the new upper frame 21 are integrated by threading a screw S1 into the new upper outer frame body 21a via the new upper inner frame body 21d. Upper frame fixing brackets 21C are attached to the outer periphery of the new upper frame 21 at multiple locations along its length. The upper frame fixing bracket 21C is molded from a metal such as steel or aluminum alloy and has an upper fixing piece 21C1 and an upper mounting piece 21C2. Upper fixing piece 21C1 is a flat plate extending from metal frame portion 21A to resin frame portion 21B, and is attached to new upper frame 21 by screwing in screw S2 while abutting against the outer peripheral surfaces of metal frame portion 21A and resin frame portion 21B. Upper mounting piece 21C2 extends from the edge located on the indoor side of upper fixing piece 21C1 to the inner peripheral side along the indoor-facing surface of new upper frame 21, and then protrudes toward the room from a position approximately halfway along new upper frame 21.

[0017] The new vertical frame 23 is configured to be symmetrical on the left and right. As shown in Figures 4, 5, 11, and 12, the metal frame portion 23A of the new vertical frame 23 has a new vertical outer frame body 23a with a cylindrical shape having a substantially rectangular cross section. A new vertical locking piece 23b extending toward the room is provided at the corner located on the interior side of the outer periphery of the new vertical outer frame body 23a. A new vertical outer hook portion 23c and a new vertical outer seal material attachment portion 23d are provided at the corner located on the interior side of the inner periphery of the new vertical outer frame body 23a. The new vertical outer hook portion 23c extends toward the room and then bends toward the outer periphery. The new vertical outer seal material attachment portion 23d is used to attach the vertical outer seal member G1 and protrudes toward the inner periphery. The resin frame portion 23B of the new vertical frame 23 has a new vertical inner frame body 23e with a cylindrical cross section that is approximately rectangular. The dimension of the new vertical inner frame body 23e along the projection direction is smaller than that of the new vertical outer frame body 23a, and the dimension along the projection direction is approximately the same as that of the new vertical outer frame body 23a. A new vertical door stop wall portion 23f is provided at the corner on the inner periphery of the new vertical inner frame body 23e that is located on the interior side of the room. The new vertical door stop wall portion 23f protrudes toward the interior from the new vertical inner frame body 23e and has a new vertical seal material mounting portion 23g for mounting a door seal member G2 on the portion facing the exterior. A new vertical inner hollow portion 23h is provided on the interior side of the new vertical inner frame body 23e. The new vertical inner hollow portion 23h has approximately the same dimensions along the front view as the new vertical inner frame main body 23e, but is smaller in dimensions along the front view. An engaging protrusion 23i is provided toward the inner periphery at the inner corner of the new vertical inner hollow portion 23h located on the indoor side. A new vertical engaging protrusion 23j is provided on the outer periphery at the corner of the new vertical inner frame main body 23e located on the outdoor side, and a new vertical inner hook portion 23k is provided on the inner periphery. The new vertical engaging protrusion 23j protrudes toward the outer periphery and is provided to correspond to the new vertical locking piece 23b of the metal frame portion 23A. The new vertical inner hook portion 23k extends toward the outside of the room and then bends toward the inner periphery, corresponding to the new vertical outer hook portion 23c of the metal frame portion 23A.

[0018] The metal frame portion 23A and the resin frame portion 23B of the new vertical frame 23 are interconnected by engaging the new vertical outer hook portion 23c with the new vertical inner hook portion 23k and by engaging the new vertical locking piece 23b with the new vertical locking protrusion 23j. Furthermore, the metal frame portion 23A and the resin frame portion 23B of the new vertical frame 23 are integrated by threading a screw S3 into the new vertical outer frame body 23a via the new vertical inner frame body 23e. Vertical frame fixing brackets 23C are attached to the outer periphery of the new vertical frame 23 at multiple locations along the length. The vertical frame fixing brackets 23C are molded from a metal such as steel or aluminum alloy and have vertical fixing pieces 23C1 and vertical mounting pieces 23C2. The vertical fixing piece 23C1 is a flat plate extending from the metal frame portion 23A to the resin frame portion 23B, and is attached to the new vertical frame 23 by screwing screws S4 into each of the metal frame portion 23A and the resin frame portion 23B while abutting the outer peripheral surfaces of the metal frame portion 23A and the resin frame portion 23B. The vertical mounting piece 23C2 extends from the edge of the vertical fixing piece 23C1 located on the indoor side to the inner peripheral side along the inner peripheral surface of the new vertical frame 23, and then protrudes toward the room from a corner located on the inner peripheral side of the new vertical frame 23. The dimension of the new vertical frame 23 along the projection direction is approximately equal to the dimension of the new upper frame 21 along the projection direction.

[0019] The above-mentioned new upper frame 21 and new vertical frame 23 are attached to the main body B by screwing a screw S5 into the main body B via the upper mounting piece portion 21C2 protruding toward the interior side of the upper frame fixing bracket 21C and the vertical mounting piece portion 23C2 protruding toward the interior side of the vertical frame fixing bracket 23C, as shown in Figures 3, 4, and 5.

[0020] More specifically, as shown in Figure 3, the new upper frame 21 is provided with an upper inner spacer D1 that protrudes inward from the existing upper door stop wall 11b on the interior side of the existing upper frame 11, and an upper frame reinforcement E1 and an upper outer spacer D2 are provided on the projected surface of the existing upper body 11a. The upper frame reinforcement E1 is a flat plate made of metal such as steel or aluminum alloy, and is attached to the upper frame fixing bracket 21C by threading screws S6. As is clear from the figure, the projected dimension of the upper frame reinforcement E1 is set to be approximately the same as the upper fixing piece 21C1 of the upper frame fixing bracket 21C. From the above-mentioned state, the upper fixing piece portion 21C1 of the upper frame fixing bracket 21C is abutted against the upper outer spacer D2, and a screw S5 is screwed into the main body B via the upper mounting piece portion 21C2 and the upper inner spacer D1, and a screw S7 is screwed into the upper frame reinforcement material E1 via the metal frame portion 21A and upper fixing piece portion 21C1 of the new upper frame 21, thereby attaching the new upper frame 21 to the inner side of the existing upper frame 11.

[0021] Similarly, for the new left vertical frame 23, which will serve as the hanging point, as shown in Figure 4, a vertical inner spacer D3 that protrudes inward from the existing vertical doorstop wall 13b is previously installed in the existing vertical frame 13 on the room side of the existing vertical doorstop wall 13b, and a vertical frame reinforcement E2 and a vertical outer spacer D4 are installed on the projected surface that will be the inner periphery of the existing vertical body 13a. The vertical frame reinforcement E2 is a flat plate made of metal such as steel or aluminum alloy, and is attached to the vertical frame fixing bracket 23C by threading screws S8 in a position corresponding to the vertical frame fixing bracket 23C. As is clear from the figure, the dimension of the vertical frame reinforcement E2 along the projected direction is set to be approximately the same as the vertical fixing piece 23C1 of the vertical frame fixing bracket 23C. From the above-mentioned state, with the vertical fixing piece portion 23C1 abutting against the vertical outer spacer D4, screw S5 is screwed into the main body B via the vertical mounting piece portion 23C2 and the vertical inner spacer D3, and screw S9 is screwed into the vertical frame reinforcement material E2 via the metal frame portion 23A and vertical fixing piece portion 23C1 of the new left vertical frame 23, thereby attaching the new left vertical frame 23 to the inner side of the existing vertical frame 13.

[0022] The new right vertical frame 23, which will be located on the door-end side, may be attached in the same manner as the new left vertical frame 23. However, in this embodiment, the vertical frame reinforcement member E2 is omitted and the new right vertical frame 23 is attached to the inner periphery of the existing vertical frame 13. That is, a vertical inner spacer D3 that protrudes inward from the existing vertical doorstop wall 13b is disposed in advance in the existing vertical frame 13 on the room side of the existing vertical doorstop wall 13b, and a vertical outer spacer D4 is disposed on the surface that will become the inner periphery of the existing vertical main body 13a. Then, with the vertical frame fixing bracket 23C abutting the vertical outer spacer D4, screws S5 are screwed into the frame B via the vertical mounting piece 23C2 and the vertical inner spacer D3, thereby attaching the new right vertical frame 23 to the inner periphery of the existing vertical frame 13. Although not shown in the figure, the new upper frame 21 is connected to each of the new vertical frames 23 on the left and right by threading screws into the screw holes 21i through the new vertical frames 23.

[0023] The new sill 22 is composed of a new sill body 22a, a new lower outer sight wall 22b, a new lower door stop wall 22c, a new lower inner sight wall 22d, and a new lower inner sight wall 22e. The new sill body 22a is formed as a plate extending in the sight direction by a body component 22A1 of the indoor frame portion 22A and a body component 22B1 of the outdoor frame portion 22B. The inner surface of the new sill body 22a extends almost horizontally. The bridge member 22C of the new sill 22 is located between a bridge mounting portion 22A2 on the body component 22A1 and a bridge mounting portion 22B2 on the body component 22B1. Screw holes 22f are provided on the outer periphery of the new sill body 22a, in the portion closest to the outdoor side and on both sides of the bridge member 22C. The new lower outer sight wall 22b extends from the exterior-side edge of the new lower frame body 22a toward the outer periphery. The new lower door stop wall 22c extends in the sight direction from the interior-side edge of the new lower frame body 22a toward the inner periphery. A new lower seal material attachment portion 22g for attaching the door seal member G2 is provided on the inner periphery edge of the new lower door stop wall 22c facing the outside. The new lower inner sight wall 22d extends in the sight direction from the new lower door stop wall 22c toward the interior of the room. Screw holes 22f are provided on the exterior-side surface of the new lower inner sight wall 22d. The new lower inner sight wall 22e extends in the sight direction from the interior-side edge of the new lower inner sight wall 22d. An attachment 29 is attached to the outer periphery of the new lower frame body 22a, on the outdoor side.

[0024] The attachment 29 is attached to the screw hole 22f located on the outermost side of the new sill body 22a and is made of a metal such as an aluminum alloy. In this embodiment, the attachment 29 includes a flat attachment body 29a, an engagement portion 29b that protrudes inward from the outer edge of the attachment body 29a, bends toward the outside, and bends again toward the inner edge, and a mating protrusion 29c that protrudes inward from the inner portion of the attachment body 29a. The attachment 29 is attached to the outer-side portion of the new sill body 22a by fitting the engagement protrusion 29c into the screw hole 22f and engaging the engagement portion 29b with the surface of the outer periphery of the new sill body 22a. When the attachment 29 is attached to the new lower frame 22, the outer peripheral surface of the attachment body 29a and the outer peripheral edge surface of the new lower inner sight wall portion 22e are positioned on the same horizontal plane.

[0025] The new sill 22 described above is installed on the dirt floor of the entrance by screwing screws S10, S11 into the existing sill 12 and the entrance porch F, respectively, with the frame support member 30 attached to the existing sill 12 in advance. More specifically, the frame support member 30 is formed from a metal such as an aluminum alloy and has a sight piece 30a extending in the sight direction and a projection piece 30b extending in the sight direction from the joint edge on the inner periphery of the sight piece 30a. The frame support member 30 is attached to the existing sill 12 by screwing screws S12 into the existing lower outer support wall 12b via the sight piece 30a, with the projection piece 30a abutting the surface of the existing lower outer support wall 12b facing the outside. The projection piece 30b of the frame support member 30 attached to the existing sill 12 has its inner peripheral projection surface located on the same plane as the inner peripheral projection surface of the existing sill body 12a. The frame support members 30 may be provided along the entire length of the existing sill 12, or may be provided at multiple positions along the length of the existing sill 12. The new sill 22 with the attachments 29 attached is positioned on the inner periphery of the existing sill 12 to which the frame support members 30 are attached. Screws S10 are threaded into the existing sill body 12a via the new lower inner projection wall 22d, and screws S11 are threaded through the attachments 29 to the portion spanning the earthen floor spacer D5 and the entrance porch F. This allows the new sill 22 to be attached to the inner periphery of the existing sill 12 between the lower ends of the new vertical frames 23. Although not shown in the figure, the new sill 22 is connected to the new vertical frames 23 by threading screws into the screw holes 22f via the left and right new vertical frames 23.

[0026] As shown in Figures 3 and 10, the new transom 24 is composed of a new transom main body 24a, a new exterior sight wall 24b, a new interior hollow section 24c, and a new transom doorstop wall 24d. The new transom main body 24a is composed of an exterior frame section 24B and is hollow and extends in the forward direction. The underside of the new transom main body 24a extends almost horizontally. The upper surface of the new transom main body 24a extends almost horizontally in the portion facing the interior, while the portion facing the exterior is lowered by one step and then gradually slopes downward toward the exterior. Bridge mounting sections 24B1 are provided on the upper and lower edges of the sight surface of the new transom main body 24a facing the exterior. The new exterior sight wall 24b extends from the exterior edge of the new transom main body 24a toward the exterior and then extends upward almost vertically. The portion of the new exterior sight wall 24b facing the interior of the room has a new FIX seal mounting portion 24e at its upper edge for mounting the exterior FIX seal member G3. The new interior hollow portion 24c is formed by the interior frame portion 24A and has a rectangular cross section extending vertically. The top and bottom surfaces of the new interior hollow portion 24c extend almost horizontally. The vertical dimension of the new interior hollow portion 24c is larger than the interior edge of the new transom main body 24a. The upper corner of the new interior hollow portion 24c facing the exterior of the room has a new transom seal mounting piece 24f for mounting the interior FIX seal member G4.
