By the way, when the heat insulating performance of the flash door is improved, a temperature difference is likely to occur between the indoor and outdoor steel plates, and a thermal expansion difference is likely to occur due to the temperature difference. In particular, the steel sheet on the outdoor side may thermally expand due to the influence of outside air temperature and direct sunlight, and when the outdoor steel sheet thermally expands, the door panel warps, causing problems in locking and light leakage. Challenges occur. For this reason, conventionally, a method has been adopted in which a channel material or a square tubular steel material is used as an aggregate to improve the rigidity of the edge of the panel and suppress the warping stress that causes the panel to warp. Since each of the indoor and outdoor steel plates is fixed to the aggregate with rivets and screws, not only the warping stress can be suppressed, but also the thermal elongation of the steel plates is regulated.

However, when the temperature of the steel plate of the flush door becomes high as in the case of a fire, the amount of heat elongation of the steel plate also increases. For this reason, if the thermal elongation of the steel sheet is regulated by the aggregate, a large warping stress is rather generated, and the panel is often warped without being suppressed by the aggregate. For this reason, there is a problem that a gap is generated between the door frame and the door body, the fire resistance is deteriorated, and flame or smoke flows in through the gap.

An object of the present invention is to provide a fitting capable of suppressing warpage of a panel due to heat or the like at the time of a fire and preventing deterioration of fire resistance performance.

The fitting of the present invention includes a fitting frame and a door body that is openably and closably attached to the fitting frame. It is composed of a metal outdoor surface material arranged on the outdoor side of the vertical bone and a metal indoor surface material arranged on the indoor side of the vertical bone, and the vertical bone is a prospect of the door body. It is characterized in that it is composed of a flat metal aggregate having a prospective piece along the direction.
According to the present invention, a flat metal aggregate such as a steel flat bar is used as the vertical bone of the door body, and the metal aggregate is arranged along the prospective direction of the door body to form a prospective piece. Therefore, when the outdoor surface material or the indoor surface material is thermally stretched and a force is applied to the metal aggregate in the direction of finding the vertical bone, the force to stop the heat elongation can be reduced. .. Therefore, in the event of a fire, the heat elongation of the outdoor surface material and the indoor surface material is stopped, so that warpage stress can be prevented from being generated in each face material, and the warp of the door body can be suppressed. Therefore, it is possible to suppress the occurrence of a gap between the door body and the fitting frame, and it is possible to prevent deterioration of the fire resistance performance. In particular, in the present invention, since the metal aggregate has a flat plate shape, the force for stopping the heat elongation of the outdoor surface material can be reduced, and the force for stopping the heat elongation of the indoor surface material can also be reduced, so that a fire can occur both indoors and outdoors. Even if it occurs, the warp of the door can be suppressed.

Therefore, it is possible to suppress the occurrence of a gap between the door body and the fitting frame, and it is possible to prevent deterioration of the fire resistance performance. In particular, in the present invention, since the metal aggregate is L-shaped, the force for stopping the heat elongation of the outdoor surface material can be reduced, and the warp of the door body can be effectively suppressed when a fire occurs on the outdoor side. Further, since a metal aggregate having an L-shaped cross section is used, when performing a double-sided pressing operation in which the outdoor surface material and the indoor surface material are pressed from both directions to cure the adhesive by sandwiching the metal aggregate, the metal bone is used.

On the other hand, as shown in FIG. 3, the extension dimension (dimension in the Y-axis direction) of the outdoor prospective surface portion 512D is different so as not to interfere with the lock case 100 provided with the latch bolt, the dead bolt (not shown) and the like. It is set shorter than the outdoor prospective surface portions 512A, 512B, and 512C.

The indoor surface material 52 includes an indoor surface portion 521 bonded to the indoor surface of the heat insulating core material 53, and indoor prospective surface portions 522A to 522D bent from the upper and lower and left and right edge edges of the indoor surface portion 521 to the outdoor side. There is.
As shown in FIG. 2, the upper and lower expected indoor surface portions 522A and 522B of the indoor surface material 52 are arranged along the metal aggregate 61 and fixed to the metal aggregate 61 with rivets 64 which are fastening members. The indoor prospective surface portions 522A and 522B are extended to the stepped portion of the convex portion 626 of the resin aggregate 62. Therefore, the outdoor prospective surface portions 512A and 512B of the outdoor surface material 51 and the indoor prospective surface portions 522A and 522B of the indoor surface material 52 are arranged at positions separated from each other in the prospective direction of the door 5.
The indoor prospective surface portions 522C and 522D are arranged along the metal aggregate 61 and are fixed to the metal aggregate 61 with rivets 64 which are fastening members. The indoor prospective surface portion 522C is extended to the stepped portion of the convex portion 626 of the resin aggregate 62. Therefore, the outdoor prospective surface portion 512C and the indoor prospective surface portion 522C are arranged at positions separated from each other in the prospective direction of the door 5, and the indoor prospective surface portion 522D has an extension dimension (extended size) so as not to interfere with the lock case 100. The dimension in the Y-axis direction) is set shorter than that of the other indoor prospective surface portions 522A to 522C, and is extended to the position of the convex portion 925 in the present embodiment.
Resin aggregates 62 and 92 are interposed between the outdoor surface material 51 and the metal aggregate 61 and the indoor surface material 52, and heat conduction from the outdoor surface material 51 to the metal aggregate 61 and the indoor surface material 52 is performed. Since it is suppressed, the heat insulating performance of the door 5 can be improved.

The heat insulating core material 53 is made of a heat insulating material made of EPS (expanded bead method polystyrene). As the heat insulating core material 53, a phenol resin-based heat insulating material may be used, or a honeycomb material (aluminum hydroxide honeycomb, ceramic honeycomb, paper honeycomb), a foam material (isocyanurate foam, urethane foam, phenol resin foam). Insulation material such as, etc. may be used.
The outdoor surface material 51 and the indoor surface material 52 are adhered to the outdoor surface and the indoor surface of the heat insulating core material 53 with an adhesive, and the outdoor prospective surface portions 512A to 512D and the indoor prospective surface portions 522A to 522D are made of resin aggregates 62 and 92 and metal. It is fixed to the aggregate 61 with an adhesive, rivets, or the like. Therefore, the door 5 is a flush door finished flat by pasting the outdoor surface material 51 and the indoor surface material 52, which are steel plates, on the aggregate 6.

The edge material 7 is formed of an extruded profile made of metal such as aluminum, and is arranged so as to straddle the outdoor prospective surface portion 512D of the outdoor surface material 51 and the face material holding surface 923 of the resin aggregate 92.
A watertight material 700 is attached to the edge material 7. The edge material 7 is positioned by abutting the outdoor surface portion 511 and the outdoor prospective surface portion 512D of the outdoor surface material 51 on continuous corner portions. The edge material 7 is formed with a through hole or the like through which the lock case 100 is inserted.
As described above, the vertical bone 90 has a structure different from that of the other upper bone 60, lower bone 70, and vertical bone 80 because the edge material 7 and the lock case 100 are attached.

Next, the bending stress of the metal aggregate 61 that mainly secures the rigidity of the aggregate 6 will be described. As shown in FIG. 4, the geometrical moment of inertia of the metal aggregate 61 made of steel having a plate-like (substantially I-shaped) cross-sectional shape is expected to have, for example, a thickness dimension t of the metal aggregate 61 of 1.2 mm. When size and 39 mm, X-axis second moment Ix = 5932mm ^4, Y-axis of the second moment Iy = 5.6 mm ^4.
On the other hand, the moment of inertia of area of a steel channel material having a substantially C-shaped cross section like a conventional aggregate has, for example, a thickness dimension t of the channel material of 1.2 mm and an estimated dimension of 36.5 mm. Assuming that the found dimension is 18 mm, the moment of inertia of area around the X axis is Ix = 4868 mm ⁴ , and the moment of inertia of area around the Y axis is ^{Iy = 1171 mm 4.}
That is, the flat plate type metal aggregate 61 of the present embodiment is characterized in that Iy is very small as compared with the conventional channel material.

Therefore, in the metal aggregate 61 of the vertical bone 80, the bending stress with respect to the force applied in the X-axis direction (finding direction) is EIy (E is the Young's modulus of the metal aggregate 61), so that it is compared with the conventional channel material. Is a very small value. Therefore, when the outdoor surface material 51 and the indoor surface material 52 are heated and thermally stretched in the X-axis direction, the metal aggregate 61 bends and deforms, allowing the heat elongation of the outdoor surface material 51 and the indoor surface material 52. do. Therefore, the warping stress applied to the outdoor surface material 51 and the indoor surface material 52 is also reduced, and as a result, the door 5 which is a panel is less likely to warp.
On the other hand, with respect to the metal aggregate 61 of the vertical bone 80, the bending stress with respect to the force applied in the Y-axis direction (probable direction) is EIx, so that the value is as large as or larger than that of the conventional channel material. Therefore, for example, the outdoor surface material 51 is heated by the heat of a fire and heats up and down, while the metal aggregate 61 and the indoor surface are insulated from the outdoor surface material 51 by the resin aggregates 62 and 92. Since the material 52 does not thermally stretch, even if stress is applied to the metal aggregate 61 in the expected direction, the metal aggregate 61 can hardly be deformed in the expected direction against the stress because the bending stress EIx is large. , The warp of the door 5 can also be suppressed.

The assembly procedure of the door 5 is as follows, for example. First, the metal aggregate 61 is arranged along the indoor prospective surface portions 522A to 522D of the indoor surface material 52 formed by cutting and bending the steel plate, and is fixed by rivets.
Next, the outer peripheral pieces 621 and 921 are aligned with the metal aggregate 61, and the outdoor side ends of the metal aggregate 61 are fitted into the holding grooves 628 and 928 to form the resin aggregates 62 and 92 with the metal aggregate. Attach to 61. Further, the heat insulating core material 53 is arranged in the space surrounded by the metal aggregate 61 and adhered to the indoor surface portion 521 of the indoor surface material 52.
Next, the outdoor surface material 51 formed by cutting and bending a steel plate is adhered to the resin aggregates 62 and 92 and the heat insulating core material 53.
Then, pressure is applied by pressing from both sides of the outdoor surface material 51 and the indoor surface material 52 to sandwich-mold the door 5.
Further, the lock case 100, wiring, edge material 7, and the like are attached. With the above, the door 5 can be assembled.
The door 5 assembled at the factory is attached to the door frame 2 with a hinge 4 at the construction site, and the entrance door 1 is constructed.

According to the first embodiment of such a configuration, there are the following effects.
Since the flat metal aggregate 61 is used as the aggregate 6 in the door 5, the moment of inertia of area Iy becomes very small. Therefore, in both cases where the outdoor side of the entrance door 1 becomes a fire and the outdoor surface material 51 is heated, and the indoor side becomes a fire and the indoor surface material 52 is heated, the heated outdoor surface The heat elongation of the material 51 and the indoor surface material 52 in the in-plane direction (X-axis direction and Y-axis direction) can be allowed by bending the metal aggregate 61, etc. In comparison, the thermal elongation of the steel sheet is not hindered, and the generation of warpage stress of the steel sheet itself can be suppressed. Therefore, it is possible to suppress the occurrence of warping of the door 5 due to the warping stress of the steel plate.
Further, since the metal aggregate 61 has a flat plate shape, the outdoor surface material 51 and the indoor surface are similarly heated regardless of whether the outdoor surface material 51 is heated or the indoor surface material 52 is heated. The generation of warpage stress of the material 52 can be suppressed, and the generation of warpage of the door 5 can be suppressed.
The upper bone 60, the lower bone 70, and the vertical bones 80 and 90 are composed of the metal aggregate 61 and the resin aggregates 62 and 92, and the resin aggregates 62 and 92 are placed between the outdoor surface material 51 and the metal aggregate 61. Since the interposition is provided, the heat insulating performance of the door 5 can be improved. Further, since the resin aggregates 62 and 92 coat the metal aggregate 61, it is possible to prevent the metal aggregate 61 from coming into direct contact with the outside air, and in this respect as well, the heat insulating performance can be improved. Further, since the metal aggregate 61 is not exposed on the peripheral surface of the door 5, the design of the door 5 can be improved.
When the door 5 is sandwich-molded, the metal aggregate 61 has a small thickness dimension and a large prospective dimension. Therefore, when only the metal aggregate 61 is provided as the aggregate 6, it easily falls down during press molding and is an outdoor surface. Misalignment of the material 51 and the indoor surface material 52 is likely to occur. On the other hand, as the aggregate 6, the resin aggregates 62 and 92 are attached to the metal aggregate 61 and integrated, so that the metal aggregate 61 can be prevented from collapsing when the door 5 is sandwich-molded, and the metal aggregate 61 can be prevented from collapsing outdoors. The misalignment of the face material 51 and the indoor face material 52 can be prevented, and the door 5 can be easily manufactured.
Further, the resin aggregates 62 and 92 are provided with outdoor piece portions 622 and 922 and convex portions 625 and 924, and are provided with a finding surface (a plane along the X-axis direction) indoors and outdoors. Therefore, during sandwich molding, the resin aggregates 62 and 92 can be pressed stably without falling, and the metal aggregate 61, the outdoor surface material 51, and the indoor surface material 52 that are attached based on the resin aggregates 62 and 92 can be pressed. Can be pressed without causing misalignment.
The metal aggregate 61 is fixed to the indoor prospective surface portions 522A to 522D of the indoor surface member 52 with rivets 64, and the resin aggregates 62 and 92 hold the outdoor side ends of the metal aggregate 61 with the holding grooves 628 and 928. Moreover, since the metal aggregate 61 and the indoor prospective surface portions 522A to 522D are in contact with each other and positioned, the metal aggregate 61, the resin aggregates 62 and 92, and the indoor surface material 52 can be positioned and arranged. Further, since the outdoor surface material 51 can be positioned by bringing the bent portion into contact with the corner portions of the resin aggregates 62 and 92, the metal aggregate 61 and the resin aggregates 62 and 92 and the outdoor surface material 51 are positioned. Can be placed. Therefore, the door 5 can be assembled by arranging the outdoor surface material 51 and the indoor surface material 52 at the correct positions with respect to the aggregate 6.

[Second Embodiment]
Next, the entrance door 1A of the second embodiment of the present invention will be described with reference to FIGS. 5 and 6. In the door 5 of the first embodiment, a flat plate (flat bar) was used as the metal aggregate 61, whereas in the door 5A of the second embodiment, a metal aggregate 61A having an L-shaped cross section was used. Is different, and other configurations are the same as those in the first embodiment. Therefore, the description of the door 5A having the same configuration as that of the door 5 will be omitted.
The metal aggregate 61A includes the prospective piece 612 along the prospective direction of the upper bone 60A, the lower bone 70A, the vertical bone 80A, and 90A constituting the aggregate 6A, and the upper bone 60A from the indoor side end of the prospective piece 612. , The lower bone 70A, the vertical bones 80A, and 90A are provided with a finding piece portion 613 extended in the finding direction.
Like the metal aggregate 61, the metal aggregate 61A is made of steel, has a thickness dimension t of 1.2 mm, an estimated dimension of 38 mm, a found dimension of the found piece 613 of 9 mm, and the like, and Ix is a metal aggregate. It is slightly smaller than the material 61 and Iy is larger than the metal aggregate 61. However, the Iy of the metal aggregate 61A without the finding piece on the outdoor side is about half as small as that of the channel material having the finding piece provided indoors and outdoors.

Such a second embodiment has the same effect as that of the first embodiment.
In particular, the metal aggregate 61A has a found piece portion 613 only on the indoor side and does not have a found piece portion on the outdoor side. Since the force to stop the thermal elongation is small and the thermal elongation is allowed to some extent, the thermal elongation of the outdoor surface material 51 is not hindered as compared with the case of being composed of the conventional channel material, so that the thermal elongation is increased. It is possible to suppress the generation of warpage stress of the outdoor surface material 51 due to the inhibition. Therefore, it is possible to suppress the occurrence of warping of the door 5 due to the warping stress of the outdoor surface material 51.
Since the metal aggregate 61A has a finding piece portion 613 on the indoor side, the force for stopping the heat elongation of the indoor surface material 52 is larger than that of the outdoor surface material 51, but it is compared with the case where the metal aggregate 61A is composed of the conventional channel material. Since the force for stopping the thermal elongation of the indoor surface material 52 is small, the generation of warpage stress of the indoor surface material 52 can also be suppressed. Therefore, it is possible to suppress the occurrence of warping of the door 5 due to the warping stress of the indoor surface material 52. Further, as in the first embodiment, by providing the resin aggregate 62, the heat insulating performance and the designability can be improved.
Since the metal aggregate 61A includes the finding piece portion 613, the metal aggregate 61A can be prevented from falling when the door 5A is pressed from both sides to cure the adhesive, and the outdoor surface material 51 and the indoor surface material 52 can be formed. The occurrence of misalignment can be prevented, and the door 5A can be stably molded.

[Third Embodiment]
Next, the entrance door 1B of the third embodiment of the present invention will be described with reference to FIGS. 7 and 8. In the doors 5 and 5A of the first and second embodiments, the upper bone 60, the lower bone 70, and the vertical bones 80 and 90 provided with the metal aggregates 61 and 61A and the resin aggregates 62 and 92 are used as the aggregate 6. rice field.
On the other hand, the entrance door 1B of the third embodiment is different in that the upper bone 60B, the lower bone 70B, the vertical bones 80B, and 90B, which are composed of only the metal aggregate 61, are used as the aggregate 6B of the door 5B. do. In the third embodiment, the same reference numerals are given to the same configurations as those in the first and second embodiments, and the description thereof will be omitted.

Since the door 5B of the entrance door 1B uses the upper bone 60B, the lower bone 70B, the vertical bones 80B, and 90B of only the metal aggregate 61, the metal aggregate 61 is circulated four times before the door 5B is pressed and molded. Assemble into a frame to form a frame. For example, as will be described in the fifth embodiment described later, the left and right ends of the metal aggregate 61 provided on the upper bone 60B and the lower bone 70B are bent, and the metal aggregate 61 provided on the vertical bones 80B and 90B is bent. The upper and lower ends may be screwed to the bent portion to assemble the frame, the metal aggregates 61 may be fixed to each other via a connecting bracket, and the frame may be assembled by welding or the like. May be good.
A heat insulating core 53 is arranged in the frame assembled of the metal aggregate 61. Since the frame is composed of the flat metal aggregate 61, the heat insulating core 53 can be arranged to a position where it is in close contact with the metal aggregate 61, and can be arranged without a gap with the metal aggregate 61. Therefore, the metal aggregate 61 and the heat insulating core 53 can be adhered and fixed with an adhesive.

The outdoor prospective surface portions 512A to 512D of the outdoor surface material 51 and the indoor prospective surface portions 522A to 522D of the indoor surface material 52 are arranged along the metal aggregate 61 and adhered to the metal aggregate 61. At this time, the dimension of the metal aggregate 61 in the prospective direction is set shorter than the dimension of the heat insulating core material 53 in the prospective direction, and the outdoor end face and the indoor end face of the metal aggregate 61 are separated from the outdoor surface portion 511 and the indoor surface portion 521. Is arranged.
The indoor side ends of the outdoor prospective surfaces 512A to 512C and the outdoor side ends of the indoor prospective surfaces 522A to 522C that are adhered to the metal aggregate 61 of the upper bone 60, the lower bone 70, and the vertical bone 80 are metal aggregates. It is extended to approximately the center position in the prospective direction of 61. However, the outdoor prospective surface portions 512A to 512C and the indoor prospective surface portions 522A to 522C are arranged so as to form a gap so that the outdoor surface material 51 and the indoor surface material 52 do not come into direct contact with each other.
The indoor side end of the outdoor prospective surface portion 512D adhered to the metal aggregate 61 of the vertical bone 90 and the outdoor side end of the indoor prospective surface portion 522D have short dimensions in the prospective direction so as not to interfere with the lock case 100. Has been done. This end is sandwiched between the edge member 7B and the metal aggregate 61.
The edge material 7B is different from the edge material 7 of the first and second embodiments in that the indoor side end is extended to a position where it is flush with the indoor surface portion 521 of the indoor surface material 52, but the other configurations are different. Similar. Therefore, the edge material 7B covers the metal aggregate 61, the outdoor prospective surface portion 512D, and the indoor prospective surface portion 522D so as not to be exposed.

In such a third embodiment, since the flat metal aggregate 61 is used as in the first embodiment, the force for stopping the thermal elongation of the outdoor surface material 51 and the indoor surface material 52 can be reduced. The generation of warpage stress of the outdoor surface material 51 and the indoor surface material 52 can be suppressed, and the generation of warpage of the door 5B due to the warp stress can also be suppressed.
Since the metal aggregate 61 is framed around four circumferences to form the frame, it is possible to prevent the metal aggregate 61 from tipping over when the door 5B is pressed from both sides to cure and mold the adhesive. Therefore, the door 5B can be stably molded even when it is not combined with the resin aggregate.
Since the upper bone 60B, the lower bone 70B, the vertical bone 80B, and 90B are composed of only the metal aggregate 61, the number of parts can be reduced and the cost can be reduced. Further, the space in which the heat insulating core material 53 can be arranged can be increased, and the heat insulating property and rigidity of the door 5B can be improved.

[Fourth Embodiment]
Next, the entrance door 1C of the fourth embodiment of the present invention will be described with reference to FIGS. 9 and 10. The door 5C of the entrance door 1C is the same as the third embodiment in that no resin aggregate is used, but the vertical bones 80C and 90C are used in the second embodiment for the prospective piece portion 612 and the finding piece portion 613. The difference is that the metal aggregate 61A provided with the above bone is used and the upper bone and the lower bone are not provided.

The door 5C of the entrance door 1C uses vertical bones 80C and 90C having only the metal aggregate 61A as the aggregate 6C. Since the door 5C does not have an upper bone and a lower bone, the metal aggregate 61A cannot be assembled in a frame shape, but since the door 5C is provided with a finding piece 613, even when the door 5C is pressed and molded, even when the door 5C is pressed and molded. The metal aggregate 61A has a structure that does not easily fall over, and can prevent misalignment of the outdoor surface material 51 and the indoor surface material 52.
The attachment structure of the outdoor surface material 51 and the indoor surface material 52 to the metal aggregate 61A in the vertical bones 80C and 90C is the same as that in the third embodiment. That is, the outdoor prospective surface portions 512A to 512C and the indoor prospective surface portions 522A to 522C are extended to substantially the center position in the prospective direction of the metal aggregate 61A, and the outdoor prospective surface portion 512D and the indoor prospective surface portion 522D do not interfere with the lock case 100. As such, the dimensions in the prospective direction are shortened.

On the other hand, since the upper bone and the lower bone are not provided, the finding surface portion 513 bent toward the heat insulating core 53 side is continuously formed on the outdoor prospective surface portions 512A and 512B of the outdoor surface material 51. Similarly, on the indoor prospective surface portions 522A and 522B of the indoor surface material 52, a finding surface portion 523 bent toward the heat insulating core material 53 is continuously formed.
The finding surface portions 513 and 523 are bonded to each other with the heat insulating member 65 interposed therebetween. The heat insulating member 65 is made of a nonflammable heat insulating material such as nonflammable polyurethane, and is adhesively fixed to the finding surface portions 513 and 523.

In such a fourth embodiment, since the metal aggregate 61A having a substantially L-shaped cross section is used as in the second embodiment, the force for stopping the heat elongation of the outdoor surface material 51 and the indoor surface material 52 is reduced. In particular, since the thermal elongation of the outdoor surface material 51 can be tolerated, the generation of warpage stress of the outdoor surface material 51 and the indoor surface material 52 can be suppressed, and the generation of warpage of the door 5C due to the warp stress can also be suppressed.
Further, since it does not have an upper bone and a lower bone, it does not regulate the heat elongation in the vertical direction of the outdoor surface material 51 and the indoor surface material 52, and also in this respect, the warp stress of the outdoor surface material 51 and the indoor surface material 52. It is possible to suppress the occurrence of warpage of the door 5C due to the warp stress.
Further, since the upper bone and the lower bone are not provided, the heat conduction through the metal aggregate 61A can be reduced, the heat insulating performance of the door 5C can be improved, the number of parts can be reduced, and the cost can be reduced.

[Fifth Embodiment]
Next, the door 5D used for the entrance door of the fifth embodiment of the present invention will be described with reference to FIG. The door 5D of the fifth embodiment is similar to the third embodiment in that the upper bone 60B, the lower bone 70B, and the vertical bones 80B and 90B, which are composed of only the metal aggregate 61, are used as the aggregate 6D. The difference is that a concave groove 531 for arranging the metal aggregate 61 is formed on the outer peripheral surface of the heat insulating core material 53.
That is, as shown in FIG. 11A, the aggregate 6D is composed of the metal aggregate 61 in a four-circumferential framework. This configuration is the same as in the third embodiment.
The width dimension of the metal aggregate 61 (dimension along the prospective direction of the door 5D) is shorter than the prospective dimension of the heat insulating core material 53. Further, a concave groove 531 in which the metal aggregate 61 is arranged is formed on the outer peripheral surface of the heat insulating core material 53 along the prospective direction.
As a result, the heat insulating core material 53 is arranged between the outdoor end face of the metal aggregate 61 and the outdoor face material 51, and between the indoor end face of the metal aggregate 61 and the indoor face material 52. Insulation performance can be improved as compared with the door 5B of the third embodiment.

Therefore, the vertical bone and the upper bone and the lower bone may be configured differently. Similarly, the upper bone and the lower bone may have different configurations. However, the same configuration has the advantage that the number of parts of the resin aggregate can be reduced.
In the first and second embodiments, the indoor side ends of the resin aggregates 62 and 92 are provided up to positions aligned with the outdoor surface portion 511, but the expected dimensions of the resin aggregate are shortened and the positions of the outdoor surface portions 511 are shortened. It may be configured so that it does not reach.
