By the way, the thermal conductivity of the expansion material is higher than the thermal conductivity of the heat insulating material. For this reason, there has been a problem that the expansive material arranged across the outer frame and the inner frame serves as a heat bridge, and the heat insulating performance of the frame body is deteriorated. Particularly in fittings such as doors, since the length dimension of the vertical frame is larger than that of the upper and lower frames, there is a problem that if the heat insulating performance of the vertical frame deteriorates, the heat insulating performance of the fitting easily decreases.

An object of the present invention is to provide a fitting that can maintain fire resistance and improve heat insulating performance.

A foam material and a second heat-foamable material arranged across the indoor member and the heat insulating member are attached, and the first heat-foamable material and the second heat-foamable material are not in contact with each other. It is characterized by

According to the present invention, since the first heat-foamable material and the second heat-foamable material are arranged so as not to contact each other, it is possible to prevent heat conduction between the first heat-foamable material and the second heat-foamable material. Therefore, even when using a heat-foamed material having a higher thermal conductivity than the heat insulating member, the first heat-foamed material and the second heat-foamed material are arranged apart from each other in the prospective direction of the vertical frame, and between the outdoor member and the indoor member. Since it is not a heat bridge, the heat insulation performance of the vertical frame can be improved compared to the case where the heat-foamed material is a heat bridge, and thus the heat insulation performance of the fitting can also be improved.
Further, the first heat-foamable material and the second heat-foamable material are arranged so as to straddle the outdoor member or the indoor member and the heat insulating member, and when the first heat-foamable material and the second heat-foamable material foam. It is possible to close the gap between the heating foam materials. Therefore, the heat insulating member of the vertical frame can be covered with each heating foam material, and the fire resistance of the fitting can be maintained.

In the fitting of the present invention, the vertical frame is provided with a tight material that can come into contact with the indoor surface of the door body, and the first heated foam material is provided at a position facing the prospective surface of the door body. The second heat-foamable material may be provided at a position facing the prospective surface of the tight material.
According to the present invention, the space between the door body and the vertical frame can be closed by the first heated foam material, and the tight material can be covered by the second heated foam material. As a result, the first heat-foamable material and the second heat-foamable material can exhibit different fireproof functions, and the fireproof performance can be further improved.

In the fitting of the present invention, the vertical frame is provided with a tight material capable of contacting an indoor surface of the door body, and the first heated foam material and the second heated foam material are prospective surfaces of the door body. May be provided at a position facing to the tight surface and not facing to the prospective surface of the tight material.
According to the present invention, since the first heated foam material and the second heated foam material both face the prospective surface of the door body, it is possible to more reliably close the space between the vertical frame and the door body and further improve the fire resistance performance. ..

According to the fitting of the present invention, since the heat-foamable material does not form a thermal bridge between the outdoor member and the indoor member, the fire resistance performance can be maintained and the heat insulation performance can be improved.

The gap may have a size capable of preventing heat conduction between the first heated foam material 37 and the second heated foam material 38, and at least the first heated foam material 37 and the second heated foam material 38 must be in contact with each other. Good.

The indoor side edge 382 of the second heated foam material 38 is set to be closer to the indoor side than the surface indoor edge 332 of the heat insulating member 33. In the present embodiment, the position of the indoor side edge 382 in the prospective direction is substantially the same as the position of the surface of the base portion 351 of the maintight material 35. That is, the maintight material 35 includes a base portion 351 made of a hard resin and a seal portion 352 made of a soft resin. The base portion 351 is a portion held by the holding piece portion 322, and the seal portion 352 is a portion that abuts on the door 5.
The second heat-foamable material 38 is arranged to face the prospective surface of the maintight material 35 (specifically, the sealing portion 352 of the maintight material 35). On the other hand, since the outdoor side edge 381 of the second heated foam material 38 is arranged closer to the indoor side than the indoor face material 52 in the prospective direction, the second heated foam material 38 does not face the prospective surface of the door 5. It is located in a position.

[Door fireproof structure]
A fireproof structure between the door 5 and the vertical frames 30 and 40 will be described with reference to FIG. 6 showing a state in which the heated foam material is foamed by a fire. Note that FIG. 6 shows the first heating foam material 37, the second heating foam material 38 provided on the vertical frame 30, and the heating foam materials 565 and 566 provided on the cover material 56 of the vertical bone 80 on the hanging side. A foamed state is shown. Since the foaming state between the vertical frame 40 and the vertical frame 90 on the door end side is the same, the description is omitted.

For example, the temperature in the vicinity of the vertical frames 30, 40 and the vertical bones 80, 90 rises due to the heat of a fire on the outdoor side, and the heating foam materials 565 and 566 provided on the cover material 56 and the first heating foam material 37, When the foaming temperature of the second heating foam material 38 (for example, 200° C.) is reached, these heating foam materials 37, 38, 565, 566 foam and expand.
At this time, since the first heated foam material 37 faces the prospective surface of the door 5, it foams and expands toward the door 5. In the present embodiment, the door 5 is also provided with the heated foam material 566 at a position facing the first heated foam material 37. Therefore, the vertical frames 30, 40 and the door 5 are opposed to each other by the first heat foam material 566. The heat-foamable material 37 and the heat-foamable material 566 are closed by being foamed and abutted.
Further, since the second heat-foamable material 38 faces the prospective surface of the maintight material 35, it foams and expands toward the maintight material 35. When a fire occurs on the outdoor side, the second heating foam material 38 foams before the main tight material 35 burns down. Therefore, the main tight material 35 is covered with the second heating foam material 38 to suppress heat transfer. it can.
Further, since the first heated foam material 37 and the second heated foam material 38 expand in the prospective direction as well, the gap between the first heated foam material 37 and the second heated foam material 38 is closed, and the surface of the heat insulating member 33 is covered with the first heat foam material. The first heating foam material 37 and the second heating foam material 38 are coated.

The heated foam material 565 foams and expands toward the side surface portion 313 of the vertical frame 30, and closes the space between the vertical frame 30 and the vertical bone 80. Therefore, the space between the door 5 and the vertical frame 30 can be closed by the foamed heating foam materials 37, 38, 565, 566.

Although not shown in the figure, other heat-foaming materials also foam and expand due to the temperature rise at the time of a fire, and close each gap as described above.
As described above, in the event of a fire, the heat-foamed materials 37, 38, 115, 615, 616, 815, 816, 817, 58, 565, 566 are foamed to seal the inside of the door 5 or the door frame 2 and the door 5. Since the gap between them is closed, the fireproof performance required in the entrance door 1 is secured.

The first heating foam material 37 and the second heating foam material 37 and the second heating foam material 38 are arranged so as not to come into contact with each other because they are arranged so as to straddle the members 33, 43. It is possible to prevent heat conduction between the heated foam materials 38. Therefore, even when the heated foam materials 37 and 38 having higher thermal conductivity than the heat insulating members 33 and 43 are used, the first heated foam material 37 and the second heated foam material 38 are separated from each other in the prospective direction of the vertical frames 30 and 40. The heat insulation of the vertical frames 30 and 40 is greater than that of the case where the heat-foaming material is a heat bridge because it is arranged as a heat bridge between the outdoor members 31 and 41 and the indoor members 32 and 42. Performance can be improved.

(2) Since the first heated foam material 37 and the second heated foam material 38 do not have to be in contact with each other, the gap size between the first heated foam material 37 and the second heated foam material 38 is also small, about 1 to 2 mm. it can. Therefore, when the first heat-foamable material 37 and the second heat-foamable material 38 foam, the gap can be closed, and the heat insulating members 33 and 43 can be covered with the heat-foamable materials 37 and 38. The required fire resistance can be secured.

(3) Since the first heated foam material 37 is provided at a position facing the prospective surface of the door 5, it expands toward the door 5 side in the event of a fire and reliably closes the door 5 and the vertical frames 30, 40. be able to. Further, in the present embodiment, the heating foam 566 facing the first heating foam 37 is also provided on the prospective surface of the door 5. For this reason, the first heat-foamable material 37 and the heat-foamable material 566 expand and expand toward the other heat-foaming material, so that each heating is performed at an intermediate position between the prospective surface of the door 5 and the side surfaces of the vertical frames 30 and 40. The foam materials 37 and 566 contact each other to close the space between the door 5 and the vertical frames 30 and 40. Therefore, it is possible to close the space between the door 5 and the vertical frames 30 and 40 in about half the time as compared with the case where the first heated foam material 37 is provided only on the vertical frames 30 and 40.

(4) Since the second heat-foamable material 38 is provided at a position facing the maintight material 35, it can expand toward the maintight material 35 and cover the maintight material 35 during a fire. Therefore, when a fire occurs on the outdoor side, the main tight material 35 can be protected by the second heated foam material 38. Further, when a fire occurs on the indoor side, even if the maintight material 35 is burned out, the second heating foam material 38 closes the indoor surface of the door 5 and the holding piece portions 322, 422, so that the flame is blocked. it can.

Further, when a fire occurs on the indoor side, even if the maintight material 35 is burnt out, the indoor-side heating foam material 38F closes the indoor surface of the door 5 and the holding pieces 322, 422, so that the flame is blocked. it can.

[Modification]
Note 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, the positional relationship between the heat insulating members 33 and 43 of the vertical frames 30 and 40 and the indoor surface material 52 of the door 5 in the prospective direction is not limited to that in the above embodiment. Therefore, the positional relationship between each heated foam material and the door 5 or the maintight materials 35 and 45 is not limited to that in each of the above-described embodiments.
For example, when providing the first heat-foamable material and the second heat-foamable material, the first heat-foamable material is provided at a position facing the door 5, and the second heat-foamable material is provided on the door 5 and the main tight materials 35 and 45. You may provide in the position which opposes. Further, the first heated foam material may be provided at a position facing the door 5 and the maintight materials 35, 45, and the second heated foam material may be provided at a position facing the maintight materials 35, 45. Similarly, the positional relationship between the outdoor side heated foam material or the indoor side heated foam material and the door 5 or the maintight materials 35 and 45 is not limited to that in the above-described embodiment.

In each of the above-described embodiments, the cover material 56 in which the heat-foamable materials 565 and 566 are laminated is attached to the prospective surface of the door 5, but the heat-foamable material is not provided on the cover material 56 and the vertical frames 30 and 40 are provided. The provided heating foam may close the door 5 and the vertical frames 30 and 40.

In the above-described 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-resistant material means a material having a property capable of withstanding combustion, specifically, a non-flammable material such as non-combustible, flame-retardant, self-extinguishing, and retarded. If the subtight materials 36 and 46 are made of such a flame-resistant synthetic resin material, the flame shielding performance can be further improved in cooperation with the heat-foaming material.
