Mode for Carrying Out the Invention

[0016] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1 to 3 show a first embodiment of the fitting of the present invention (an embodiment of the invention according to claim 1 and claim 2). This fitting is applied to the entrance door of a house, and includes a frame 1 attached to a building opening, and a door 2 attached to the frame 1 so as to rotate outward and open by a hinge 10.

[0017] The frame 1 is formed by framing an upper frame 11, a lower frame 12, a door tip side vertical frame 13, and a suspension side vertical frame 14, which are formed of extruded aluminum alloy materials. As shown in FIG. 1, the door tip side vertical frame 13 and the suspension side vertical frame 14 have a hollow portion 15 with a substantially rectangular cross-section on the outdoor side, and a prospective surface 16 on the inner peripheral side extends to the indoor side from the hollow portion 15, and a door stop portion 17 protrudes inward on the indoor side end of the prospective surface 16. A resin cover material 18 is attached to the indoor side of the door stop portion 17. A first tight material 3 is attached to the prospective surface 16 on the inner peripheral side of the door tip side vertical frame 13 and the suspension side vertical frame 14. The first tight material 3 is curved toward the indoor side and the tip portion abuts against a position closer to the indoor side of the prospective surface 29 on the outer peripheral side of the door 2. Also, a second tight material 4 is attached to the outdoor side surface of the door stop portion 17, and the second tight material 4 abuts against the finding surface on the indoor side of the door 2. The first tight material 3 and the second tight material 4 are formed of, for example, EPDM (ethylene propylene rubber). In this fitting, by providing the tight materials 3 and 4 double between the vertical frames 13 and 14 and the door 2 in this way, the water stop performance and airtight performance are improved.

[0018] As shown in Fig. 1, at the position on the outer peripheral side of the second tight material 4 on the prospective surface 16 on the inner peripheral side of the door end side vertical frame 13 and the suspension end side vertical frame 14, a heat-expandable material 5 that foams and expands by the heat of a fire during a fire is provided along the longitudinal direction of the vertical frames 13 and 14 over the entire length of the vertical frames 13 and 14. Such a heat-expandable material 5 can be appropriately selected and used from commercially available products. For example, a product named "Fiblock" manufactured by Sekisui Chemical Co., Ltd. can be used. This is an organic refractory material that utilizes plastic technology. In a normal state, it is in the form of a thin sheet, and when heated to 200°C or higher, it expands 5 to 40 times in the thickness direction to form a heat insulation layer. It does not disappear during a fire and does not generate harmful gases. In addition, since Fiblock has an adhesive layer with release paper on one side, the release paper can be peeled off and it can be easily adhesively attached.

[0019] As shown in Fig. 2, the upper frame 11 has a hollow portion 15 with a substantially rectangular cross-section on the outdoor side, similar to the vertical frames 13 and 14. The prospective surface 16 on the inner peripheral side extends to the indoor side of the hollow portion 15, and a door stop portion 17 protrudes inward on the indoor side end of the prospective surface 16. A resin cover material 18 is attached to the indoor side of the door stop portion 17. A first tight material 3 that abuts against the prospective surface 29 of the door 2 is provided on the prospective surface 16 on the inner peripheral side of the upper frame 11. In addition, a second tight material 4 is attached to the outdoor side surface of the door stop portion 17, and the second tight material 4 abuts against the finding surface on the indoor side of the door 2. A heat-expandable material 19 is provided along the longitudinal direction of the upper frame 11 over the entire length of the upper frame 11 at a position adjacent to the indoor side of the first tight material 3 on the prospective surface 16 on the inner peripheral side of the upper frame 11.

[0020] As shown in Fig. 2, the lower frame 12 has a door stop portion 17 protruding inward on the indoor side. A tight material 20 is attached to the outdoor side surface of the door stop portion 17, and the tight material 20 abuts against the finding surface on the indoor side of the door 2. A resin hinge 21 is attached to the indoor side of the door stop portion 17, and the hinge 21 covers the attachment portion of the tight material 20.

[0021] As shown in FIGS. 1 and 2, the door 2 has a so-called flash structure in which a frame 22 with a U-shaped cross section is assembled into a four-sided frame, a heat insulating material 23 such as a polystyrene foam board is arranged inside the frame, and panels 24 and 25 made of steel plates are attached to the outdoor side and the outdoor side. The panels 24 and 25 have their edges bent in the prospective direction and are fixed to the frame 22 with rivets 26. The frame 22 is reinforced by arranging a metal frame 22b inside a resin frame 22a. As shown in FIG. 3, the door 2 is attached to the vertical frame 14 on the hanging side with hinges 10 arranged at three positions: the upper part, the lower part, and the middle part on the hanging side. A handle 27 is attached to the vertical middle part on the door tip side of the door 2, and locks 28 are provided above and below the handle 27. The deadbolt of the lock 28 (not shown) engages with a receiver provided on the vertical frame 13 on the door tip side to lock the door.

[0022] As shown in FIG. 1, on the prospective surfaces 29 on the door tip side and the hanging side of the door 2, a heat-expandable material 6 is provided along the longitudinal direction of the frame 22 over the entire length of the frame 22 at a position adjacent to the outdoor side of the tip portion of the first tight material 3 in contact with the door 2. An edge material 30 made of an aluminum profile is attached to the prospective surface 29 on the door tip side of the door 2. The edge material 30 has a smoke baffle 31 on the outdoor side, and the smoke baffle 31 hides the gap between the vertical frame 13 on the door tip side and the door 2 from the outdoor side. As shown in FIG. 2, a heat-expandable material 32 is provided along the longitudinal direction of the frame 22 over the entire length of the frame 22 at a position adjacent to the outdoor side of the tight material 20 on the lower surface of the door 2.

[0023] FIG. 4 is a cross-sectional view of the fitting according to the first embodiment, showing the state when a fire occurs. FIG. 5 is a comparative example of the fitting according to the first embodiment, showing the state when a fire occurs when the heat-expandable material 6 is not provided on the prospective surfaces 29 on the door tip side and the hanging side of the door 2. When a fire occurs, the door 2 tries to expand vertically due to the heat of the fire, so a warp occurs such that the heated surface side bulges. The hanging side of the door 2 is constrained by the hinge 10 to the vertical frame 14 on the hanging side, and the door tip side is engaged with the vertical frame 13 on the door tip side by the lock 28 at the vertical middle part. Therefore, the warp becomes larger at the upper and lower parts of the door tip side. As shown in Fig. 4, in the fitting of this embodiment, the heat-expandable material 5 provided on the expected surface 16 of the vertical frames 13 and 14 during a fire foams and expands within the space between the first tight material 3 and the second tight material 4 to block the gap between the vertical frames 13 and 14 and the door 2 from the indoor side. Moreover, the heat-expandable material 6 provided near the first tight material 3 on the expected surfaces 29 on the leading edge side and the hanging end side of the door 2 foams and expands to block the gap between the frames 1 and the expected surfaces 16 and 29 of the door 2. Therefore, as shown in the figure, even if the door 2 warps due to heat and the upper and lower parts on the leading edge side move in the indoor-outdoor direction, no gap will occur between the vertical frames 13 and 14 and the door 2. On the other hand, in the comparative example where there is no heat-expandable material 6 on the expected surfaces 29 on the leading edge side and the hanging end side of the door 2, as shown in Fig. 5, when the door 2 warps due to heat and the upper and lower parts on the leading edge side move in the indoor-outdoor direction, a gap 33 will occur between the door 2 and the leading edge side vertical frame 13. Note that no gap will occur on the hanging end side of the door 2 even with only the heat-expandable material 5 provided on the hanging end side vertical frame 14.

[0024] Also, in the fitting of the first embodiment, during a fire, the heat-expandable material 19 provided on the inner peripheral side expected surface 16 of the upper frame 11 foams and expands to block the gap between the upper frame 11 and the door 2. Moreover, the heat-expandable material 32 provided on the lower surface of the door 2 foams and expands to block the gap between the lower frame 12 and the door 2. Thus, in the fitting of this embodiment, since the gaps between the frame 1 and the door 2 are blocked by the heat-expandable materials 5, 6, 19, and 32 on all four sides, it prevents flames and smoke from communicating between the indoor and outdoor through the gap between the frame 1 and the door 2, and exhibits fireproof performance.

[0025] Figs. 6 to 8 show a second embodiment of the fitting according to the present invention (an embodiment of the invention according to claim 3). This fitting is applied to an entrance door in the same manner as the first embodiment, and includes a frame 1 attached to the building opening and a door 2 attached to the frame 1 so as to rotate outward and open by a hinge 10.

[0026] The leading edge side vertical frame 13 and the hanging end side vertical frame 14 are formed of aluminum profiles. As shown in Fig. 6, they have a door contact portion 17 protruding inward on the indoor side, and a tight material 7 is attached to the outdoor side surface of the door contact portion 17, and the tight material 7 is in contact with the indoor side finding surface of the door 2. On the prospective surfaces 16 on the inner peripheral sides of the leading-edge side vertical frame 13 and the suspension-side vertical frame 14, a first heat-expandable material 8 is provided along the longitudinal direction facing the position on the indoor side of the prospective surface 29 of the door 2. Further, on the prospective surfaces 16 on the inner peripheral sides of the leading-edge side vertical frame 13 and the suspension-side vertical frame 14, a second heat-expandable material 9 is provided along the longitudinal direction at a position on the outer peripheral side of the tight material 7 on the indoor side with respect to the first heat-expandable material 8. As shown in FIG. 8, the first heat-expandable material 8 is provided only at the upper and lower portions of the prospective surfaces 16 on the inner peripheral sides of the leading-edge side vertical frame 13 and the suspension-side vertical frame 14. The lengths of the first heat-expandable materials 8 at the upper and lower portions are each 450 mm. On the other hand, the second heat-expandable material 9 is provided over the entire length of the vertical frames 13 and 14. As shown in FIG. 6, on the prospective surfaces 16 on the inner peripheral sides of the leading-edge side vertical frame 13 and the suspension-side vertical frame 14, ridges 34 are provided along the longitudinal direction, and the indoor-side edge of the first heat-expandable material 8 and the outdoor-side edge of the second heat-expandable material 9 can be positioned by abutting them against the ridges 34 respectively, whereby the operation of attaching the first heat-expandable material 8 and the second heat-expandable material 9 can be performed easily and accurately.

[0027] The upper frame 11 is formed of an aluminum profile. As shown in FIG. 7, a door contact portion 17 protrudes inward on the indoor side, and a tight material 7 is attached to the outdoor-side surface of the door contact portion 17, and the tight material 7 is in contact with the finding surface on the indoor side of the door 2. A heat-expandable material 35 is provided along the longitudinal direction of the upper frame 11 over the entire length of the upper frame 11 at a position on the outer peripheral side of the tight material 7 on the prospective surface 16 on the inner peripheral side of the upper frame 11.

[0028] The lower frame 12 is formed of an aluminum profile. As shown in FIG. 7, a door contact portion 17 protrudes inward on the indoor side, and a tight material 7 is attached to the outdoor-side surface of the door contact portion 17, and the tight material 7 is in contact with the finding surface on the indoor side of the door 2. A resin-made step 21 is attached to the indoor side of the door contact portion 17, and the attachment portion of the tight material 7 is covered with the step 21. A heat-expandable material 36 is provided along the longitudinal direction of the lower frame 12 over the entire length of the lower frame 12 at a position on the outer peripheral side of the tight material 7 on the prospective surface 16 on the inner peripheral side of the lower frame 12.

[0029] FIG. 9 is a cross-sectional view of the fitting according to the second embodiment, showing the state when a fire occurs. FIG. 10 is a comparative example of the fitting according to the second embodiment, showing the state when a fire occurs in the case where the first heat-expandable material 8 is not provided. As shown in FIG. 9, in the fitting of the present embodiment, when a fire occurs, the second heat-expandable material 9 provided on the expected surface 16 on the outer peripheral side of the tight material 7 of the vertical frames 13 and 14 foams and expands to block the gap between the vertical frames 13 and 14 and the door 2 from the indoor side. Moreover, the first heat-expandable material 8 provided above and below the second heat-expandable material 9 on the outdoor side of the expected surface 16 of the vertical frames 13 and 14 foams and expands to block the gap between the vertical frames 13 and 14 and the expected surfaces 16 and 29 of the door 2. Therefore, as shown in the figure, even if the door 2 is thermally warped and the upper and lower parts on the door tip side move in the indoor-outdoor direction, no gap is generated between the vertical frames 13 and 14 and the door 2. On the other hand, in the comparative example where the first heat-expandable material 8 is not provided, as shown in FIG. 10, when the door 2 is thermally warped and the upper and lower parts on the door tip side move in the indoor-outdoor direction, a gap 33 is generated between the vertical frame 13 on the door tip side. Since the suspension side of the door 2 is restrained by the hinge 10, no gap is generated even with only the second heat-expandable material 9. Therefore, in the second embodiment, the first heat-expandable material 8 on the suspension side can be omitted.

[0030] In the second embodiment, the second heat-expandable material 9 can also be provided on the found surface (for example, the outdoor side surface of the door stop portion 17) of the vertical frames 13 and 14 on the outer peripheral side of the tight material 7. In this case, since the second heat-expandable material 9 on the found surface is on the indoor side of the first heat-expandable material 8 on the expected surface, when a fire occurs, the second heat-expandable material 9 on the found surface foams and expands toward the outdoor side and pushes the first heat-expandable material 8 on the expected surface to the outdoor side. Therefore, the gap between the door 2 warped to the outdoor side and the vertical frames 13 and 14 can be surely blocked.

[0031] In addition, in the fitting of the second embodiment, when a fire occurs, the heat-expandable material 35 provided on the expected surface 16 on the inner peripheral side of the upper frame 11 foams and expands to block the gap between the upper frame 11 and the door 2. Also, the heat-expandable material 36 provided on the expected surface 16 on the inner peripheral side of the lower frame 12 foams and expands to block the gap between the lower frame 12 and the door 2. Thus, in the fitting of this embodiment, since the gaps between the frame 1 and the door 2 are blocked by the heat-expandable materials 8, 9, 35, and 36 on all four sides, it prevents flames and smoke from communicating between the indoors and outdoors through the gap between the frame 1 and the door 2, and exhibits fireproof performance.

[0032] FIG. 11 shows a third embodiment of the fitting according to the present invention (an embodiment of the invention according to claim 3). This fitting, similar to the first embodiment, is applied to an entrance door and is a parent-child door including a frame 1 attached to the building opening, and a parent door (door) 37 and a small door 38 attached to the frame 1 so as to rotate outward and open by a hinge 10.

[0033] On the expected surfaces 16 on the inner peripheral sides of the left and right vertical frames 39, 39, a first heat-expandable material 8 and a second heat-expandable material 9 are provided in the same manner as in the second embodiment. On the door tip surface of the small door 38, an edge material (corresponding to the door tip side vertical frame 13 of the second embodiment) 40 formed of an aluminum profile is provided over the entire length in the height direction of the small door 38. The edge material 40 has a door contact portion 41 protruding to the outer peripheral side of the small door 38 on the indoor side, and a tight material 7 is attached to the outdoor side surface of the door contact portion 41, and the tight material 7 is in contact with the finding surface on the indoor side of the parent door 37. On the expected surface 42 on the outer peripheral side of the small door of the edge material 40, a first heat-expandable material 8 is provided along the longitudinal direction facing the position closer to the indoor side of the expected surface 29 of the parent door 37. Further, on the expected surface 42 on the outer peripheral side of the small door of the edge material 40, a second heat-expandable material 9 is provided along the longitudinal direction at a position on the outer peripheral side of the tight material 7 and on the indoor side of the first heat-expandable material 8. As shown in FIG. 12, the first heat-expandable material 8 is provided only at the upper and lower portions of the expected surface 42 on the outer peripheral side of the small door of the edge material 40. The lengths of the first heat-expandable materials 8 at the upper and lower portions are 450 mm each. On the other hand, the second heat-expandable material 9 is provided over the entire length of the edge material 40. On the upper frame 11 and the lower frame 12, a tight material 7 and heat-expandable materials 35, 36 are provided in the same manner as in the second embodiment shown in FIG. 7.

[0034] FIG. 13 is a cross-sectional view of the fitting according to the third embodiment, showing the state when a fire occurs. FIG. 14 is a comparative example of the fitting according to the third embodiment, showing the state when a fire occurs in the case where the first heat-expandable material 8 is absent. As shown in FIG. 13, in the fitting of the present embodiment, when a fire occurs, the second heat-expandable material 9 provided on the prospective surface 42 on the outer peripheral side of the tight material 7 of the edge material 40 of the small door 38 foams and expands to block the gap between the main door 37 and the small door 38 from the indoor side. Moreover, the first heat-expandable materials 8 provided above and below the second heat-expandable material 9 on the outdoor side of the prospective surface 42 of the edge material 40 of the small door 38 foam and expand to block the gap between the prospective surfaces of the main door 37 and the small door 38. Therefore, as shown in the figure, even if the main door 37 is thermally warped and the upper and lower parts on the door tip side move in the indoor-outdoor direction, no gap will occur between the main door 37 and the small door 38. The gaps between the hanging side of the main door 37 and the small door 38 and the vertical frames 39, 39 are blocked by the foamed and expanded first heat-expandable material 8 and second heat-expandable material 9. On the other hand, in the comparative example where the first heat-expandable material 8 is absent, as shown in FIG. 14, when the main door 37 is thermally warped and the upper and lower parts on the door tip side move in the indoor-outdoor direction, a gap 33 will occur between the edge material 40 of the small door 38. Since the hanging sides of the main door 37 and the small door 38 are constrained by the hinge 10, no gap will occur even with only the second heat-expandable material 9. Therefore, in the third embodiment, the first heat-expandable material 8 on the hanging side can be omitted.

[0035] In the third embodiment, the second heat-expandable material 9 can also be provided on the finding surface (for example, the outdoor side surface of the door stop portion 41) of the edge material 40 on the outer peripheral side of the tight material 7. In this case, since the second heat-expandable material 9 on the finding surface is on the indoor side compared to the first heat-expandable material 8 on the prospective surface, when a fire occurs, the second heat-expandable material 9 on the finding surface foams and expands toward the outdoor side and pushes the first heat-expandable material 8 on the prospective surface to the outdoor side. Therefore, the gap between the main door 37 warped to the outdoor side and the small door 38 can be surely blocked.

[0036] Figure 15 shows a fourth embodiment of the fitting according to the present invention (an embodiment of the invention according to claim 4). This fitting is applied to the entrance door in the same manner as the first embodiment, and includes a frame 1 attached to the body opening, and a door 2 attached to the frame 1 so as to rotate and open to the outdoor side by a hinge 10. It is different from the first embodiment in that the frame 1 is provided with heat insulation performance by a heat insulation bridge material 45.

[0037] As shown in Fig. 15, the door tip side vertical frame 13 and the suspension side vertical frame 14 are heat insulation profiles composed of an outdoor side profile 43 and an indoor side profile 44 made of an aluminum alloy extrusion profile, and a resin heat insulation bridge material 45 connecting the outdoor side profile 43 and the indoor side profile 44. At the indoor side end position of the inner peripheral side expected surface 16 of the outdoor side profile 43, a first tight material 3 that abuts against the expected surface 29 of the door 2 is provided. The indoor side profile 44 has a door stop portion 17 that protrudes toward the inner peripheral side, and a second tight material 4 that abuts against the indoor side finding surface of the door 2 is provided on the outdoor side surface of the door stop portion 17. A heating foam material 5 that foams and expands by the heat of the fire during a fire is provided along the longitudinal direction of the vertical frames 13 and 14 over the entire length of the vertical frames 13 and 14 at a position on the outer peripheral side of the second tight material 4 of the inner peripheral side expected surface 16 of the indoor side profile 44. The upper frame (not shown) is also a heat insulation profile composed of an outdoor side profile 43 and an indoor side profile 44 made of an aluminum alloy extrusion profile, and a resin heat insulation bridge material 45 connecting the outdoor side profile 43 and the indoor side profile 44, similar to the vertical frames 13 and 14.

[0038] As shown in Fig. 15, on the expected surfaces 29 of the door tip side and the suspension side of the door 2, a heating foam material 6 is provided along the longitudinal direction of the frame 22 over the entire length of the frame 22 at a position adjacent to the outdoor side of the tip portion of the first tight material 3 that abuts against the door 2.

[0039] Since the upper frame and the vertical frames 13 and 14 of the fitting of this embodiment are heat insulation profiles composed of an aluminum outdoor side profile 43 and an indoor side profile 44 and a resin heat insulation bridge material 45 connecting the outdoor side profile 43 and the indoor side profile 44, it has heat insulation performance. Furthermore, similar to the first embodiment, in the fitting of this embodiment, the heat-expandable material 5 provided on the expected surface 16 of the vertical frames 13 and 14 expands and foams in the space between the first tight material 3 and the second tight material 4 during a fire, blocking the gap between the vertical frames 13 and 14 and the door 2 from the indoor side. Moreover, the heat-expandable material 6 provided near the first tight material 3 on the expected surfaces 29 on the door tip side and the hanging end side of the door 2 expands and foams to block the gap between the expected surfaces 16 and 29 of the frame 1 and the door 2. Therefore, even if the door 2 warps due to heat and the upper and lower parts on the door tip side move in the indoor-outdoor direction, no gap will occur between the vertical frames 13 and 14 and the door 2 (see Fig. 4).

[0040] Fig. 16 shows the fifth embodiment of the fitting according to the present invention (the embodiment of the invention according to claim 5). This fitting is applied to an entrance door in the same manner as the second embodiment and includes a frame 1 attached to the building opening and a door 2 attached to the frame 1 so as to rotate outward and open by means of a hinge 10. The difference from the second embodiment is that the frame 1 is provided with heat insulation performance by a heat insulation bridge material 45.

[0041] As shown in Fig. 16, the door tip side vertical frame 13 and the hanging end side vertical frame 14 are heat-insulated profiles composed of an outdoor profile 43 and an indoor profile 44 made of an extruded aluminum alloy profile, and a resin heat insulation bridge material 45 connecting the outdoor profile 43 and the indoor profile 44. At the indoor side end position of the expected surface 16 on the inner peripheral side of the outdoor profile 43 of the door tip side vertical frame 13, a first heat-expandable material 8 is provided along the longitudinal direction of the vertical frame 13. The first heat-expandable material 8 is provided with its indoor side edge coinciding with the indoor side edge of the expected surface 16 on the inner peripheral side of the outdoor profile 43 so as not to be covered by the heat insulation bridge 45. Also, similar to the second embodiment, the first heat-expandable material 8 is provided only at the upper and lower parts of the entire length of the vertical frame 14 (see Fig. 8). As shown in Fig. 16, the indoor profile 44 has a door stop portion 17 protruding toward the inner peripheral side, and a tight material 7 that abuts against the indoor finding surface of the door 2 is provided on the outdoor side surface of the door stop portion 17. At the position on the outer peripheral side of the tight material 7 on the expected surface 16 on the inner peripheral side of the indoor profile 44, a second heat-expandable material 9 that expands and foams by the heat of a fire during a fire is provided along the longitudinal direction of the vertical frame 13 over the entire length of the vertical frame 13. The hanging-side vertical frame 14 is provided only with the second heat-expandable material 9 and not with the first heat-expandable material 8. The upper frame (not shown) is also a heat-insulating profile made of an outdoor-side profile 43 and an indoor-side profile 44, which are aluminum alloy extrusion profiles, and a resin heat-insulating bridge material 45 that connects the outdoor-side profile 43 and the indoor-side profile 44, similar to the vertical frames 13 and 14.

[0042] Since the fitting of this embodiment is a heat-insulating profile composed of an outdoor-side profile 43 and an indoor-side profile 44 made of aluminum and a resin heat-insulating bridge material 45 that connects the outdoor-side profile 43 and the indoor-side profile 44 for the upper frame and the vertical frames 13 and 14, it has heat-insulating performance. Furthermore, similar to the second embodiment, in the fitting of this embodiment, the second heat-expandable material 9 provided on the expected surface 16 on the outer peripheral side of the tight material 7 of the vertical frames 13 and 14 expands and foams during a fire to block the gap between the vertical frames 13 and 14 and the door 2 from the indoor side. Moreover, the first heat-expandable materials 8 provided at the upper and lower parts of the inner peripheral side expected surface 16 outside the heat-insulating bridge material 45 of the door-tip-side vertical frame 13 expand and foam to block the gap between the door-tip-side vertical frame 13 and the expected surfaces 16 and 29 of the door 2. Therefore, even if the door 2 warps thermally and the upper and lower parts on the door-tip side move in the indoor-outdoor direction, no gap is generated between the vertical frames 13 and 14 and the door 2 (see Fig. 9). Since the first heat-expandable material 8 is provided on the inner peripheral side expected surface 16 of the outdoor-side profile 43 so as not to be covered by the heat-insulating bridge material 45, the first heat-expandable material 8 can be easily attached, and moreover, the first heat-expandable material 8 is difficult to peel off.

[0043] As described above, this building fitting (first embodiment) includes a frame 1 and a door 2. The door 2 rotates to open and close. The frame 1 has a first tight material 3 that abuts against the expected surface 29 of the door 2, a second tight material 4 that abuts against the found surface of the door 2, and a heat-expandable material 5 that foams in the space between the first tight material 3 and the second tight material 4 during a fire. On the expected surfaces 16, 29 of the frame 1 or the door 2, a heat-expandable material 6 is also provided near the first tight material 3 and on the side opposite to the second tight material 4 with respect to the first tight material 3. Thus, during a fire, the gap between the frame 1 and the door 2 is blocked by the heat-expandable materials 5, 6, so that fireproof performance can be exhibited. On the expected surfaces 16, 29 of the frame 1 or the door 2, a heat-expandable material 6 is also provided near the first tight material 3 and on the side opposite to the second tight material 4 with respect to the first tight material 3. Thus, even when the door 2 warps due to the heat of the fire during a fire, no gap is generated between the frame 1 and the door 2. Moreover, in this building fitting (first embodiment), since the frame 1 is made of aluminum, it is less likely to deform or melt during a fire compared to a frame 1 made of resin or a frame 1 with an aluminum outdoor side and a resin indoor side, and the fireproof performance can be improved. Moreover, the heat-expandable material 5 that foams in the space between the first tight material 3 and the second tight material 4 during a fire is provided on the expected surface 29 of the aluminum frame 1 facing the inner peripheral side. Therefore, when a fire occurs, the heat-expandable material 5 can quickly foam and expand to block the gap between the frame 1 and the door 2, and the fireproof performance is further improved.

[0044] Moreover, this building fitting (first embodiment) includes a frame 1 and a door 2. The door 2 rotates to open and close. The frame 1 has a tight material (first tight material) 3 that abuts against the expected surface 29 on the closing side in the opening and closing direction of the door 2. Heat-expandable materials 5, 6 that block the gap between the expected surfaces 16, 29 of the frame 1 and the door 2 during a fire are provided on the opening side and the closing side of the door 2 near the tight material 3. Thus, during a fire, the gap between the frame 1 and the door 2 is blocked by the heat-expandable materials 5, 6, so that fireproof performance can be exhibited. The provision of the heat-expandable material 5 on the opening side of the door 2 near the tight material 3 also ensures that no gap is generated between the frame 1 and the door 2 even when the door 2 warps due to the heat of the fire during a fire. In addition, in this building fixture (first embodiment), since the frame 1 is made of aluminum, it is difficult for the frame 1 to deform or melt during a fire compared to a case where the frame 1 is made of resin or where the outdoor side of the frame 1 is made of aluminum and the indoor side is made of resin, and the fire prevention performance can be improved. Moreover, since the heat-expandable material 5 on the closing side of the door 2 near the tight material 3 is provided on the expected surface 16 of the aluminum frame 1 toward the inner peripheral side, the heat-expandable material 5 can quickly foam and expand to block the gap between the frame 1 and the door 2 when a fire occurs, further improving the fire prevention performance.

[0045] This building fixture (second and third embodiments) includes a frame 1 and doors (door 2, main door 37), and the doors 2, 37 rotate to open and close. The frame (frame 1, edge material 40) has a tight material 7 that abuts against the finding surface on the closing side in the opening and closing direction of the doors 2, 37. A first heat-expandable material 8 is provided on the expected surface of the frame 1, 40 or the doors 2, 37 closer to the closing side of the doors 2, 37. By providing a second heat-expandable material 9 on the expected surface or the finding surface of the frame 1, 40 on the closing side of the doors 2, 37 and on the outer peripheral side of the tight material 7, the gap between the frame 1, 40 and the doors 2, 37 can be blocked by the first and second heat-expandable materials 8, 9 during a fire, thus enabling the fire prevention performance to be exhibited. By providing the first heat-expandable material 8 on the expected surface of the frame 1, 40 or the doors 2, 37 closer to the closing side of the doors 2, 37, even when the doors 2, 37 warp due to the heat of the fire during a fire, no gap will occur between the frame 1, 40 and the doors 2, 37. The first heat-expandable material 8 is provided at the upper and lower parts of the expected surface of the frame 1, 40 on the door tip side or the doors 2, 37, so that the gap caused by the warping of the doors 2, 37 can be effectively blocked with a small amount of the heat-expandable material 8. When the second heat-expandable material 9 is provided on the finding surface of the frame 1, 40 on the outer peripheral side of the tight material 7, the second heat-expandable material 9 foams and expands in the expected direction to push the first heat-expandable material 8 during a fire, so that the gap between the warped doors 2, 37 and the frame 1, 40 can be more reliably blocked.

[0046] This building component (4th embodiment) includes a frame 1 and a door 2. The door 2 rotates to open and close. The frame 1 includes an outdoor-side profile 43 and an indoor-side profile 44, a heat-insulating bridge material 45 connecting the outdoor-side profile 43 and the indoor-side profile 44, a first tight material 3 abutting on the expected surface 29 of the door 2, a second tight material 4 abutting on the found surface of the door 2, and a heat-expandable material 5 provided on the frame expected surface 16 on the indoor side of the heat-insulating bridge material 45 and foaming in the space between the first tight material 3 and the second tight material 4 during a fire. On the expected surfaces 16, 29 of the frame 1 or the door 2, a heat-expandable material 6 is also provided near the first tight material 3 and on the side opposite to the second tight material 4 with respect to the first tight material 3. Thus, heat-insulating performance is obtained by the heat-insulating bridge material 45, and during a fire, the gap between the frame 1 and the door 2 is blocked by the heat-expandable materials 5, 6, so that fireproof performance can be exhibited. On the expected surfaces 16, 29 of the frame 1 or the door 2, a heat-expandable material 6 is also provided near the first tight material 3 and on the side opposite to the second tight material 4 with respect to the first tight material 3. Thus, even when the door 2 warps due to the heat of the fire during a fire, no gap is generated between the frame 1 and the door 2.

[0047] This building component (5th embodiment) includes a frame 1 and a door 2. The door 2 rotates to open and close. The frame 1 includes an outdoor-side profile 43 and an indoor-side profile 44, a heat-insulating bridge material 45 connecting the outdoor-side profile 43 and the indoor-side profile 44, and a tight material 7 abutting on the found surface on the closing side in the opening and closing direction of the door 2. A first heat-expandable material 8 is provided on the expected surfaces 16, 29 of the frame 1 or the door 2 on the outdoor side of the heat-insulating bridge material 45, and a second heat-expandable material 9 is provided on the expected surface 16 or the found surface of the frame 1 on the indoor side of the heat-insulating bridge material 45 and on the outer peripheral side of the tight material 7. Thus, heat-insulating performance is obtained by the heat-insulating bridge material 45, and during a fire, the gap between the frame 1 and the door 2 is blocked by the first and second heat-expandable materials 8, 9, so that fireproof performance can be exhibited. A first heat-expandable material 8 is provided on the expected surfaces 16, 29 of the frame 1 or the door 2 on the outdoor side of the heat-insulating bridge material 45. Thus, even when the door 2 warps due to the heat of the fire during a fire, no gap is generated between the frame 1 and the door 2.

[0048] The present invention is not limited to the embodiments described above. The material and cross-sectional shape of the frame can be changed as appropriate. The structure of the door is arbitrary and is not limited to a flush door as in the embodiment, and may be a stile door or the like. In the second and third embodiments, the first heat-insulating foam material on the hanging side can be omitted. In the second, third, and fifth embodiments, the first heat-insulating foam material may be provided on the expected surface of the door, and the second heat-insulating foam material can be provided on the finding surface of the frame on the outer peripheral side of the tight material (such as the outdoor side surface of the door contact part). This fitting can be applied not only to the entrance door but also to all fittings equipped with a door that rotates and opens.
