By the way, in the frame, the thermal expansion refractory material (heated foam material) is adhered to the prospective surface of the frame and exposed on the inner surface of the frame, so that the heat foam material is easily visible when the door is opened. However, there is a problem that the designability is deteriorated. In particular, since the vertical frame is more likely to be in the line of sight of the user than the upper frame and the lower frame, it is required that the heat-foamable material be less noticeable in the vertical frame.
Further, the thermal expansion refractory material provided on the prospective surface of the frame is for closing the cracks generated in the noncombustible tight material, and is not for closing the gap between the door and the frame.
Therefore, there is a demand for a fitting frame that includes a vertical frame that can close the gap between the door body and the fitting frame and that does not deteriorate the design, and a fitting frame that includes the vertical frame.

An object of the present invention is to provide a fitting frame and a fitting including a vertical frame provided with a heat-foamable material that can close a gap between a door and the fitting frame and does not deteriorate the design.

Further, since the brackets 630 and 830 connected to the metal aggregates 620 and 820 are formed in a short piece shape and only about 2 to 5 pieces are provided, the brackets 630 and 830 are provided on the indoor surface material 52 via the brackets 630 and 830. It is possible to suppress heat transfer. In particular, the brackets 630 and 830 are made of angle material, and the portion closest to the indoor surface material 52 is the edge of the receiving piece portions 631 and 831 and has a small area. Therefore, the brackets 630 and 830 and the indoor surface material 52 are The heat outflow during the period can be reduced.
Since the noncombustible heat insulating material 54 is arranged in the space between the metal aggregates 620 and 820 and the indoor surface material 52, the heat insulating performance can be further improved. Therefore, the door 5 with high heat insulation can be obtained.

(2) The metal aggregates 620, 820 and the brackets 630, 830 are connected by the connecting tools 633, 833, and the outdoor surface material 51 and the indoor surface material 52 are further connected via the resin aggregates 610, 810. Since the rivets 65 are fixed to the brackets 620 and 820 and the brackets 630 and 830, even if the resin aggregates 610 and 810 are burned out in the event of a fire, the outdoor face material 51, the metal aggregates 620 and 820, the brackets 630 and 830, the indoors The face material 52 can be maintained in a connected state. Therefore, the form of the door 5 can be maintained at the time of fire, and the flame shielding performance can be secured.

(3) Since the noncombustible heat insulating material 54 is disposed at least between the plurality of brackets 630 and across the brackets 830, the space between the brackets 630 and 830 can be closed with the noncombustible heat insulating material 54.
For this reason, the volume of the space that the heating foam materials 616, 816, 618, and 819 provided around the noncombustible heat insulating material 54 need to be closed at the time of foaming becomes smaller than that in the case where the noncombustible heat insulating material 54 is not provided. The amount of the foam materials 616, 816, 618, and 819 can be significantly reduced, the cost can be reduced, and the rigidity of the resin aggregates 610 and 810 can be secured.
Further, since the heat-foamable material 618 has the non-combustible heat insulating material 54, it can be surely foamed on the upper frame 10 side and the lower frame 20 side, and the gap between the upper frame 10 and the upper bone 60 and the lower frame 20 are reduced. It is possible to reliably close the gap between the lower bones 70.

(4) Since the inside of the door 5 can be sealed by the heat-foaming materials 615, 616, 618, 815, 816, 817, 818, 819, even if the resin aggregates 610, 810 are burnt out, the heat insulating core material 53 It is possible to close the communication place between the inner space of the door 5 provided with and the outside of the door 5. Therefore, even if gas is generated from the heated insulating core material 53, the gas can be prevented from flowing out of the door 5.

(5) Since the heat-foamable materials 615 to 618 and 815 to 819 provided on the resin aggregates 610 and 810 are manufactured by coextrusion molding when the resin aggregates 610 and 810 are manufactured, the resin aggregates 610 and 810 are manufactured. As compared with a case where a separately produced heat-foamable material is attached later, the assembling property and the productivity at the time of manufacturing can be improved. Also, if the heated foam material is attached afterwards, the heated foam material may peel off due to aging deterioration, and regular maintenance is required, but if it is manufactured by coextrusion molding, it may deteriorate due to aging. Peeling of the heated foam material does not occur easily, and deterioration of quality can be prevented.
Further, when the heat-foamable material is attached later, it is difficult to design for ensuring the fireproof performance because it is structurally restricted by the position where it is attached to the resin aggregate, but like the present embodiment. The simultaneous extrusion molding has a high degree of freedom in the arrangement position and shape of the heat-foamable material, and therefore the fireproof performance can be easily ensured. Moreover, the amount (volume) of the heat-foamable material having low rigidity can be suppressed to a necessary minimum, and the strength required for the resin aggregates 610 and 810 can be easily ensured.

(6) The heat-foaming material 617 and the heat-foaming material 58 form a first heat-foaming material line that is continuous for four rounds on the prospective surface of the door 5, and the heat-foaming material 618 and the heat-foaming materials 565 and 566 form the door 5. Since a second heated foam material line that is continuous for four rounds is formed on the prospective plane of the above, a double flame shielding line can be formed between the door frame 2 and the door 5 in the prospective direction, and flame shielding performance is improved. it can.
Further, since the double heated foam material line is formed on the outdoor side and the indoor side with the accessory such as the lock case 6 interposed therebetween, the gas generated from the heated heat insulating core material 53 flows out from the accessory itself. Even, it is possible to seal between the double heated foam lines.
Further, since the metal edge material 55 and the resin edge material 56 are not the structure of the door 5, the degree of freedom in the structure and the shape is high, and the restriction on the arrangement position of the heating foam material is small. Therefore, the positions of the heat-foaming materials 58, 565, 566 on the metal edge material 55 and the resin edge material 56 are easily located at the positions in the prospective direction of the heat-foaming materials 617, 618 provided on the upper bone 60 and the lower bone 70. It is possible to easily configure the first heated foam material line and the second heated foam material line which are continuous four times around the prospective surface of the door 5.

(7) Among the heat-foamable materials 615-618, 815-819 provided on the resin aggregates 610, 810, the heat-foamable materials 615, 616, 815, 816 exposed on the surface side of the resin aggregates 610, 810 are outdoors. The surface material 51 and the indoor surface material 52 are covered, and the other heating foam materials 617, 618, 817 to 819 are exposed on the inner surface side (rear surface side) of the resin aggregates 610, 810, and are exposed on the front surface side. do not do. Therefore, the heated foam materials 615 to 618 and 815 to 819 are not exposed on the front surface side of the door 5, so that the designability can be improved.

(8) Since the heat-foamable materials 565 and 566 provided on the resin edge material 56 are also provided on the back surface side of the resin edge material 56 and are not exposed on the front surface side, the designability can be improved.
Further, the heat-foamable material 58 provided on the metal edge material 55 is disposed inside the groove 552 of the metal edge material 55, that is, in the pocket portion, and only a part thereof is exposed on the side surface of the door 5, so that the heat-foamable material 58 is also inconspicuous. It is possible to improve the design.
Further, since these heated foam materials 565, 566, 58 are not exposed on the surfaces of the metal edge material 55 and the resin edge material 56 of the door 5, they should contact the subtight material 36 and the subtight material 46 when the door 5 is opened and closed. There is no. Therefore, the heated foam materials 565, 566, 58 are not worn and the quality can be maintained.
Further, since the metal edge material 55 and the resin edge material 56 are attached to the vertical bones 80 and 90 of the door 5, the resin aggregate 810 of the vertical bones 80 and 90 can be covered with the edge materials 55 and 56, and the door 5 design It is possible to improve the property.

(9) In the prospective direction of the door 1, the resin edge material 56 is arranged so as to straddle the outdoor side and the indoor side of the subtight materials 36 and 46, and the heat-foamable material 565 is disposed on the subtight materials 36 and 46. Since it expands to the outdoor side and the heated foam material 566 expands to the indoor side of the subtight materials 36 and 46, the subtight materials 36 and 46 are sandwiched by the respective heated foam materials 565 and 566, so that the door 5 is expected. The state of contact with the surface can be maintained. In particular, since it is possible to cover and protect the sub-tight materials 36 and 46 with the heat-foamable material 565 and the heat-foamable materials 566, 34, and 44, it is possible to reduce burnout of the sub-titite materials 36 and 46 which are not flame resistant, or a time to burn out Can be delayed, and the subtight materials 36, 46 and the respective heat-foamable materials 565, 566, 34, 44 can close the space between the door frame 2 and the door 5 to ensure the edge blocking performance. Therefore, the space between the door frame 2 and the door 5 can be closed by the sub-tight materials 36 and 46 and the heat-foaming material, and the flame-shielding performance can be improved as compared with the case where only the heat-foaming material is closed.
When the door frame 2 and the door 5 are closed only with the subtight materials 36 and 46, when the pressure difference between the subtight materials 36 and 46 is generated indoors and outdoors, the subtight materials 36 and 46 are turned up and the door 5 is closed. However, since the foaming materials 566, 34, and 44 are filled on the indoor side of the subtight materials 36 and 46, even if a pressure difference occurs inside and outside the subtight materials 36 and 46, the door 5 It is possible to maintain the contact state with and to maintain the flame shielding performance.
Further, since the subtight materials 36 and 46 and the respective heat-foamable materials 565 and 566 are in contact with the side surface of the door 5, even if the door 5 is warped, the contact state with the side surface of the door 5 can be maintained. Also, the flame shielding performance can be maintained.

(10) Since the watertight material 57 is provided with the heated foam material 571, the gap portion between the metal edge material 55 and the outdoor members 31, 41 can be closed with the heated foam material 571 in the event of a fire.

(11) At least a part of the heated foam materials 14, 34, 44 provided on the indoor members 12, 32, 42 overlaps (wraps) the prospective surface of the door 5 and faces the prospective surface of the door 5. Therefore, when a part of the indoor members 12, 32, 42 is burnt out, the heated foam materials 14, 34, 44 foam on the prospective surface side of the door 5 and can close the gap with the prospective surface of the door 5. ..
Further, since these heated foam materials 14, 34, 44 are provided in the hollow portions 121, 321, 421 and are not exposed on the surfaces of the indoor members 12, 32, 42, the design of the door frame 2 can be improved.

(12) At least a part of the heat-foamable materials 34, 44 provided on the indoor members 32, 42 is such that the mounting positions of the subtight materials 36, 46 and the maintight materials 35, 45 are in the prospective direction of the door frame 2. Since it is arranged between the attached holding pieces 322, 422, the space surrounded by the main tight materials 35, 45 and the sub tight materials 36, 46 can be filled with the heated foam materials 34, 44. The flame shield performance can be improved.
Further, when the heat-foamable materials 34, 44 are foamed, they can be expanded in the direction in which the sub-tight materials 36, 46 and the main-tight materials 35, 45 are pressed against the door 5, so that the vertical frames 30, 40, etc. Even if the heat warps, the space between the door frame 2 and the door 5 can be reliably closed, and the flame shielding performance can be improved. In particular, the tight material that comes into contact with the found surface of the door 5 is likely to have a portion that cannot be brought into close contact with the door 5 when the door 5 is warped, but by providing the sub-tight materials 36 and 46 that come into contact with the prospective surface of the door 5, Therefore, even if the door 5 or the like warps, the close contact with the door 5 can be maintained and the flame shielding performance can be maintained.

[Modification]
It should be noted that the present invention is not limited to the configurations described in the above embodiments, and modifications within a range in which the object of the present invention can be achieved are included in the present invention.
For example, as the door frame, as shown in FIGS. 18 and 19, a door frame 2A may be used in which the upper frame 10A and the vertical frames 30A and 40A are made of an aluminum heat insulating material. Note that the door 5 and the lower frame 20 have the same configurations as those in the above-described embodiment, and thus the description thereof will be omitted.
The upper frame 10A is configured by connecting an aluminum outdoor member 11A and an aluminum indoor member 12A with a heat insulating member 13A such as urethane resin. The vertical frames 30A, 40A are configured by connecting aluminum outdoor members 31A, 41A and indoor members 32A, 42A with heat insulating members 33A, 43A such as urethane resin.
In the upper frame 10A and the vertical frames 30A, 40A, the outdoor members 11A, 31A, 41A and the indoor members 12A, 32A, 42A are connected via a connecting bracket 17A. As a result, even when the heat insulating members 13A, 33A, 43A are burnt out, the outdoor members 11A, 31A, 41A and the indoor members 12A, 32A, 42A can be maintained in a connected state. Further, heating foam materials 14A, 34A, 44A are attached to the surfaces of the heat insulating members 13A, 33A, 43A of the upper frame 10A and the vertical frames 30A, 40A, that is, the surfaces on the door 5 side. As a result, at the time of fire, the heated foam materials 14A, 34A, 44A expand and cover the heat insulating members 13A, 33A, 43A, so that the heat insulating members 13A, 33A, 43A can be prevented from burning. In addition, since the door has a large vertical height, the vertical frames 30A, 40A and the like are bent at the time of a fire to easily form a gap with the door 5, but the vertical foam frames 30A, 40A have the heated foam materials 34A, 44A. If pasted, the expansion of the heating foam materials 34A and 44A can close the gap between the door 5 and the flame shielding performance.
Further, since the heat-foamable materials 34A and 44A are arranged between the mounting positions of the main tight materials 35 and 45 and the holding pieces of the indoor members 32A and 42A that hold the sub-tight materials 36 and 46, the tight foam materials 34A and 44A are each tight. The materials 35, 45, 36, and 46 can be hidden to make it difficult to visually recognize, and the design can be improved. Further, since the outdoor side of the subtight materials 36 and 46 can be closed by the heated foam material 565 and the indoor side can be closed by the heated foam materials 566, 34A and 44A, the flame shielding performance can be improved.

In the present invention, the heat-foamable material is not limited to the example of the above embodiment. For example, reinforcing ribs or the like may be provided in the inner spaces of the hollow portions 121, 321, 421 of the indoor members 12, 32, 42, and a heating foam material may be provided in the reinforcing ribs or the like.
Further, the heat-foamable material provided on the indoor members 12, 32, 42 is not limited to the one manufactured by coextrusion molding of resin parts, and may be integrated with the resin parts by a manufacturing method other than coextrusion molding. Alternatively, a separately produced heated foam material may be bonded to the resin component.
Further, the heated foam materials 34 and 44 provided on the vertical frames 30 and 40 only need to have the outdoor side edge position P0 set at least between the positions P1 and P2, and the indoor side edge position P3 is The volume may be set in consideration of the volumes of the heat-foamable materials 34 and 44 according to the space to be filled at the time of foaming, the mold for coextruding the indoor members 32 and 42, and the like.

In the above embodiment, the subtight materials 36 and 46 are made of TPO and the maintight materials 35 and 45 are made of EPDM or PVC, but the materials are not limited to these. For example, the subtight materials 36 and 46 and the maintight materials 35 and 45 may be made of flame-resistant materials. The flame-retardant material means a material having a property capable of withstanding combustion, specifically, a non-combustible material such as non-combustible, flame-retardant, self-extinguishing, and retarded. When the subtight materials 36 and 46 are formed of such a flame-resistant synthetic resin material, the flame-shielding performance can be further improved in cooperation with the heat-foamable materials 565, 566, 34 and 44.

The fitting of the present invention is the door 1 that does not include the daylighting section, but a door 5 that has the daylighting section may be used. Further, the fitting of the present invention is not limited to the entrance door, but can be used as various doors such as a self-exiting door. At this time, the present invention can be applied to a fitting provided with two doors, a parent door and a child door, and further applicable to a sliding door type fitting.
