The indoor side ends of the outdoor prospective surface portions 513C and 513D and the outdoor prospective surface portions 513C and 513D, which are bent from the left and right edge edges of the 512C and 512D and the extension portions 512C and 512D to the indoor side (Z-axis direction). It is provided with outdoor finding surface portions 514C and 514D which are bent from the edge to the heat insulating core material 53 side (Y-axis direction).
As shown in FIG. 3, a lock 6 provided with a latch bolt 6A, a dead bolt (not shown), and a metal edge material 7 such as aluminum are attached to the outdoor prospective surface portion 513D on the door end side. There is. Therefore, the extension dimension (dimension in the X-axis direction) of the extension portion 512D is set shorter than that of the other extension portions 512A, 512B, and 512D.

The indoor surface material 52 includes an indoor surface portion 521 bonded to the indoor surface of the heat insulating core material 53, and peripheral portions 520A to 520D provided around the indoor surface portion 521.
As shown in FIG. 2, the upper and lower peripheral edges 520A and 520B of the indoor surface member 52 are formed continuously from the upper and lower edge edges of the indoor surface member 521 and are formed on the outdoor side along the upper and lower surfaces of the heat insulating core member 53. From the outer peripheral surface portions 522A and 522B, the indoor finding surface portions 523A and 523B extending upward and downward from the outer peripheral surface portions 522A and 522B, and the indoor finding surface portions 523A and 523B to the upper and lower surfaces of the heat insulating core material 53. It is provided with an indoor prospective surface portion 524A and 524B extending along the outdoor side.
The extension dimensions (dimensions in the Y-axis direction) of the indoor finding surface portions 523A and 523B are shorter than the extension dimensions of the extension portions 512A and 512B. Further, the indoor finding surface portions 523A and 523B are formed by folding back steel plates, and have a thickness dimension of two steel plates.

As shown in FIG. 3, the peripheral edge portion 520C on the hanging side of the indoor surface portion 521 is the outer peripheral surface portion 522C bent from the edge of the indoor surface portion 521 on the hanging side to the outdoor side along the side surface of the heat insulating core material 53. An indoor finding surface portion 523C extending from the outer peripheral surface portion 522C to the vertical frame 30 side, and an indoor prospective surface portion 524C extending from the indoor finding surface portion 523C to the outdoor side along the side surface of the heat insulating core material 53 are provided. Like the indoor finding surface portions 523A and 523B, the indoor finding surface portion 523C is formed by folding back a steel plate, and has a thickness dimension of two steel plates. Therefore, the peripheral edge portion 520C is configured in the same manner as the peripheral edge portions 520A and 520B.

As shown in FIG. 3, the peripheral edge portion 520D on the door end side of the indoor surface portion 521 is the outer peripheral surface portion 522D bent from the edge of the indoor surface portion 521 on the door end side to the outdoor side along the side surface of the heat insulating core material 53. And an indoor finding surface portion 523D extending from the outer peripheral surface portion 522D to the vertical frame 40 side.
For this reason, the peripheral edge portion 520D has an edge of the indoor finding surface portion 523D as the edge of the indoor facing member 52, and is not configured by folding the steel plate like the indoor finding surface portion 523C. It differs from the peripheral portions 520A to 520C in that the peripheral portions 520A to 520C do not have a portion corresponding to the indoor prospective surface portions 524A to 524C.

As shown in FIGS. 2 to 4, the indoor side end of the outer peripheral surface of the door 5, that is, the prospective surface facing the prospective surface of the door frame 2 at the door 5 intersects with the indoor surface along the indoor surface material 52. At the corners, recesses (steps) 57 are formed which are partitioned by the outer peripheral surface portions 522A to 522D of the indoor surface material 52 and the indoor finding surface portions 523A to 523D.

The outdoor surface material 51 and the indoor surface material 52 directly fasten the outdoor finding surface portions 514A to 514D and the indoor finding surface portions 523A to 523D with rivets 65, which are fastening members. Since the outdoor surface material 51 and the indoor surface material 52 are steel plates and have a small thickness, they are fastened using rivets 65. For example, when a back plate is provided on the outdoor finding surface portions 514A to 514D, they are fastened. A screw may be used as a member.

A heat insulating member 60 is arranged between the outdoor finding surface portions 514A to 514D and the indoor finding surface portions 523A to 523D.
The heat insulating member 60 may be any material that can suppress heat conduction between the outdoor surface material 51 and the indoor surface material 52 to improve heat insulating properties, and may be a general heat insulating material such as urethane resin or nonflammable polyurethane. It may be a heat insulating material having nonflammability such as.
The heat insulating member 60 is configured to prevent the outdoor surface material 51 and the indoor surface material 52 from coming into direct contact with each other when the outdoor finding surface portions 514A to 514D and the indoor finding surface portions 523A to 523D are fastened with rivets 65. .. Therefore, the heat insulating member 60 may be arranged at least at the fastening portion of the rivet 65, and a plurality of piece-shaped heat insulating members may be arranged at intervals. However, in the present embodiment, the heat insulating member 60 is long. It is formed as a heat insulating member 60. Therefore, the heat insulating member 60 is arranged over the entire length between the outdoor finding surface portions 514A to 514D and the indoor finding surface portions 523A to 523D.
Further, as shown in FIG. 4, the heat insulating member 60 includes a protrusion 61 to which the end edges of the outdoor finding surface portions 514A to 514D are brought into contact with each other. The protrusion 61 is arranged between the edge of the outdoor finding surface portions 514A to 514D and the indoor prospective surface portions 524A to 524C, and is configured so that the outdoor finding surface portions 514A to 514D do not come into direct contact with the indoor prospective surface portions 524A to 524C. ing.
Therefore, through holes penetrating in the prospective direction are formed at predetermined intervals in the outdoor finding surface portions 514A to 514D, the heat insulating member 60, and the indoor finding surface portions 523A to 523D, and the outdoor surface material 51 and the outdoor surface material 51 and the rivets 65 inserted through the through holes are formed. The indoor surface material 52 is fastened with the heat insulating member 60 interposed therebetween.

The edge material 7 is formed of an extruded metal material such as aluminum, and is fixed to the outdoor prospective surface portion 513D by using a rivet or an adhesive (not shown).

A resin member 8 is attached to the recess 57 at the peripheral edge of the door 5. The shape of the resin member 8 will be described with reference to FIG. In FIG. 4, the lock 6 is omitted.
The resin member 8 extends from the outer peripheral side end portion of the outdoor surface portion 81 to the indoor side and faces the prospective surfaces (lower surface portion 113, upper surface portion 213, side surface portions 313, 413) of the door frame 2. It includes a prospective surface portion 82, a finding surface portion 83 facing the holding piece portions 122, 222, 222, and 422, and a connecting portion 84 formed in an arc shape in cross section to connect the prospective surface portion 82 and the finding surface portion 83.

The thickness dimension (dimension in the prospective direction) of the end portion of the outdoor surface portion 81 that abuts on the heat insulating member 60 is larger than that of the other portion of the outdoor surface portion 81. Therefore, the outdoor surface portion 81 of the resin member 8 arranged on the upper surface, the lower surface, and the side surface on the hanging side of the door 5 is press-fitted into the gap between the outdoor finding surface portions 514A to 514C and the indoor finding surface portions 523A to 523C. Further, the outdoor surface portion 81 of the resin member 8 arranged on the side surface on the door end side is press-fitted between the indoor side end portion of the edge material 7 and the indoor finding surface portion 523D.

A groove 831 is formed on the outdoor surface of the finding surface portion 83 (the surface facing the indoor finding surface portions 523A to 523D). Each resin member 8 is attached to the door 5 by inserting a locking piece of an edge cap (not shown) into the groove 831.

In such a resin member 8, the finding surface portion 83 is set as the indoor surface portion by setting the dimension in the expected direction (Z-axis direction) from the outdoor surface portion 81 to the finding surface portion 83 based on the estimated dimensions of the outer peripheral surface portions 522A to 522D. It is set so that it has almost the same surface as 521. Therefore, a step is not generated between the indoor surface portion 521 and the finding surface portion 83.
Further, the resin members 8 provided on the peripheral edges 520A to 520C are provided in the finding direction from the prospective surface portion 82 to the tip end portion of the finding surface portion 83 (the resin members 8 provided above and below the door 5 are provided in the Y-axis direction on the hanging side. By setting the dimensions of the resin member 8 (in the X-axis direction) from the outer peripheral surface portions 522A to 522C of the indoor surface material 52 to the outdoor prospective surface portions 513A to 513C of the outdoor surface material 51, the prospective surface portion 82 can be formed. It is set so as to be substantially the same surface as the outdoor prospective surface portions 513A to 513C. Therefore, a step is not generated between the outdoor prospective surface portions 513A to 513C and the prospective surface portion 82.

The resin member 8 having such a structure is manufactured by extrusion-molding a heat-expandable resin material in which a heat-expandable material such as heat-expandable graphite is mixed with a polyurethane resin, an epoxy resin, or the like, and is foamed. When heated to a temperature, the entire resin member 8 foams and expands.
At this time, the prospective surface portion 82 is provided so as to face the prospective surface (lower surface portion 113, upper surface portion 213, side surface portion 313, 413) of the door frame 2, and foams toward the prospective surface of the door frame 2. Therefore, the prospective surface portion 82 constitutes the first heated foaming portion.
The finding surface portion 83 is provided so as to face the indoor finding surface of the door frame 2, that is, the holding piece portions 122, 222, 222, 422 to which the tight materials 15, 25, 35, 45 are attached, and the door frame 2 Foams toward the indoor side finding surface. Therefore, the second heated foaming portion is formed by the finding surface portion 83.
Since the connecting portion 84 is curved in an arc shape, it foams in an oblique direction intersecting the prospective direction and the finding direction. Therefore, the connecting portion 84 foams toward, for example, the heat insulating materials 13, 33, and 43.

The fireproof structure between the door 5 and the door frame 2 will be described with reference to FIGS. 5 and 6 showing a state in which the resin member 8 is foamed between the door end side of the door 5 and the vertical frame 40. Note that FIG. 5 shows an outdoor side heating state in which the outdoor side of the door 5 was heated and tested, and FIG. 6 shows an indoor side heating state in which the indoor side of the door 5 was heated and tested.

As shown in FIG. 5, in the outdoor side heating state, the outdoor surface material 51 and the like heat-extend, so that the upper end portion and the lower end portion of the door 5 warp so as to move to the indoor side.
