Since a flammable or nonflammable interposition member is arranged, even if the surface mounting member melts or falls off due to a flame or the like, the flame penetrates through the flame retardant or nonflammable interposition member in the insertion hole Can be suppressed. For this reason, it is possible to provide a door that has a hole on the surface of the door and is difficult for a flame to penetrate.

  In this door body, the interposition member includes an inner portion located in the panel body when inserted into the insertion hole, and an outer portion located outside the panel body and in contact with the surface. And the internal portion extends from the distal end portion toward the external portion side, a distal end portion that can be inserted into the insertion hole, a connecting portion that connects the external portion and the distal end portion, and And an extension part that can be elastically deformed in the inner and outer directions of the insertion hole in the in-plane direction of the surface material, and when the inner part is inserted into the panel body, the extension part It is desirable that the end portion on the outer portion side is located outside the insertion hole.

  According to such a door body, the extension part of the intervention member that extends from the distal end part toward the external part side has an end part on the external part side when the internal part is inserted into the panel body. Since it is located in the area outside the insertion hole in the in-plane direction of the surface material, it is possible to prevent the inserted interposed member from falling off. In addition, the interposition member is easy to insert because the tip portion can be inserted into the insertion hole, and when inserted, the end on the outer side is located in a region outside the insertion hole in the in-plane direction of the surface material. Since the protruding portion can be elastically deformed in the inner and outer directions of the insertion hole, it can be easily attached only by inserting the inner portion into the panel body from the distal end side.

In such a door body, it is desirable that a heating foam material is provided on the insertion space side of the intervention member.
According to such a door body, when heated by a fire or the like, the heated foam material is foamed into the insertion space, so that it is possible to more reliably suppress the penetration of the flame from the insertion hole.

In this door, it is preferable that the heating foam material is placed and attached to a portion of the interposition member located below the insertion space.
According to such a door body, since the heating foam is placed and attached to the portion located below the insertion space in the interposed member, it can be prevented from peeling off from the interposed member. Is possible. Further, since the heating foam material is provided on the inner surface of the extending portion that can be elastically deformed in the in-out direction of the insertion hole in the in-plane direction of the surface material, the projecting portion becomes the heating foam material when the projecting portion is inserted. Even if it contacts, the extension part is elastically deformed and the entry of the protrusion is not hindered. That is, it is possible to attach the surface mounting member by having the protrusions inserted into the insertion hole with reliability while having fire prevention performance.

In this door, it is preferable that the heating foam material is disposed in a region outside the insertion hole in the in-plane direction of the surface material.
According to such a door, since the heating foam material is disposed outside the insertion hole in the in-plane direction of the surface material, the protrusion does not contact the heating foam material when the protrusion is inserted. For this reason, since the approach of the protrusion is not hindered, it is possible to attach the surface mounting member by reliably inserting the protrusion into the insertion hole while having fire prevention performance.

The slide piece 14 includes a slider main body 14b having a substantially rectangular parallelepiped shape, and a positioning protrusion 14a protruding from the slider main body 14b to the indoor side.

  The slider body 14b has recesses 14c that are recessed inward on the left and right side surfaces and extend in the vertical direction. The slider body 14b is attached to the recess 133a of the cap body 13 so that the guide protrusion 133e is inserted into the groove 14c. The slider main body 14b of this embodiment is lightly press-fitted into the recess 133a, and is configured not to slide in a state where no external force is applied, but to slide along the guide protrusion 133e when an external force is applied.

  The positioning protrusion 14a is provided so as to protrude from substantially the center of the indoor side surface of the slider body 14b to the indoor side. The positioning projection 14a has a cross shape when cut along a plane parallel to the surface of the panel body 2, and the tip side has a taper shape so that the widths of the top, bottom, left and right are narrowed toward the tip. ing. The position of the positioning projection 14a on the slider body 14b side is almost equal to the width and height of the rectangular positioning hole 6a provided in the surface material 6 that forms the surface on the outdoor side of the panel body 2 in both the vertical and horizontal widths. It is formed to match.

  Each cosmetic molding 10 is attached to the panel body 2 by being inserted into the cosmetic material body 11 in a state where the slide piece 14 is mounted in the concave portion 133 a of the left insertion portion 133 and the right insertion portion 134. At this time, a double-sided tape is provided on the indoor side surface of the inwardly extending piece 11f of the decorative material body 11, and as shown in FIG. 7, positioning protrusions provided at the upper and lower ends of the decorative molding 10 14a is inserted into the insertion space S of the interposition member 20 mounted in the positioning hole 6a of the surface material 6 forming the outdoor side surface of the panel body 2, and is fixed with a double-sided tape. At this time, when both the upper and lower end caps 12 are provided with the slide pieces 14, at least the cosmetic molding 10 is positioned in the left-right direction, and only the end cap 12 on either the upper end side or the lower end side slides. When the other end cap 12 including the piece 14 is the end cap 12 in which the cap main body 13 and the slide piece 14 are integrated, the cosmetic molding 10 is also positioned in the vertical direction.

  According to the door 1 of the present embodiment, the insertion space S is formed in the positioning hole 6a provided in the surface material 6 of the panel body 2 and into which the positioning projection 14a of the decorative molding 10 is inserted. Since the nonflammable steel plate interposed member 20 disposed between the core 4 and the core member 4 is disposed, even if the decorative molding 20 is melted or dropped due to a flame or the like, the intervention in the positioning hole 6a is performed. The member 20 can prevent the flame from penetrating indoors and outdoors. For this reason, it is possible to provide the door 1 which has a positioning hole 6a on the surface of the door 1 and hardly allows a flame to penetrate.

  Further, the extended portion 24 extending from the distal end portion 22 to the external portion 25 side of the intervention member 20 is an end portion on the external portion 25 side when the internal portion 21 is inserted into the panel body 2. Since 24a is located in a region outside the positioning hole 6a, it is possible to prevent the inserted interposed member 20 from falling off. Further, the interposition member 20 has a distal end portion 22 formed smaller than the positioning hole 6a, and an extended portion 24 where the end portion 24a on the outer portion 25 side is positioned outside the positioning hole 6a when inserted. Since it can be elastically deformed in the in-plane direction of the positioning hole 6 a in the in-plane direction of the surface material 6, it can be easily attached only by inserting the internal portion 21 into the panel body 2 from the front end portion 22 side.

  Further, when heated by a fire or the like, the heat-expandable graphite 26 provided in the insertion space S foams, so that it is possible to more reliably suppress the penetration of the flame from the positioning hole 6a.

  Further, since the heat-expandable graphite 26 is placed on and attached to the lower extending portion 24 positioned below the insertion space S in the interposition member 20, the heat-expandable graphite 26 is attached to the interposition member. It is possible to prevent peeling off 20. Further, since the thermally expandable graphite 26 is provided on the upper surface 24b of the extending portion 24 that can be elastically deformed in the in-plane direction of the positioning hole 6a in the in-plane direction of the surface material 6, the positioning projection 14a is inserted. Even when the positioning protrusion 14a comes into contact with the thermally expandable graphite 26, the extended portion 24 is elastically deformed and the entry of the positioning protrusion 14a is not hindered. That is, it is possible to attach the cosmetic molding 10 by having the positioning projection 14a inserted into the positioning hole 6a with certainty while having fireproof performance.

  Further, since the thermally expandable graphite 26 is disposed in a region outside the positioning hole 6a, the positioning protrusion 14a does not contact the thermally expandable graphite 26 when the positioning protrusion 14a is inserted. For this reason, since the approach of the positioning protrusion 14a is not hindered, it is possible to attach the cosmetic molding 10 by reliably inserting the positioning protrusion 14a into the positioning hole 6a while having fire prevention performance.

  In the above embodiment, the positioning hole 6a into which the positioning protrusion 14a is inserted has a rectangular shape. However, even if the positioning hole 6a is circular or elliptical, there is an insertion space in which the protrusion can be inserted by being locked to the surface material. It does not matter as long as it is formed.

  In the said embodiment, although the surface attachment member was used as the cosmetic molding, it is not restricted to this, You may be other cosmetics and other members. Moreover, although the protrusion inserted into the insertion hole is a positioning protrusion, the present invention is not limited to this. For example, a panel such as a protrusion for preventing rotation that prevents the fixing member from rotating when screwing is used. Any protrusion that protrudes toward the body may be used. Moreover, although the example where the cosmetic mall 10 is attached to the surface on the outdoor side has been described, it may be the surface on the indoor side.

  In the above-described embodiment, the example in which the positioning protrusions 14 a provided so as to be able to change the interval between them is provided on the end cap 12, but is not limited thereto. It may be provided.

  In the said embodiment, although the entrance door 1 was mentioned as an example and demonstrated as a door, it is not restricted to this, You may be a door which partitions the interior and exterior, such as a living room. Moreover, it is not restricted to a door, A shoji such as a sliding door or a FIX shoji may be used.

  In the above embodiment, the surface material 6 and the frame 5 that cover the panel body 2 indoors and outdoors are made of non-combustible steel plates. However, non-combustible metals such as stainless steel and iron are of course difficult. You may comprise with a flammable material.

  Moreover, in the said embodiment, although the core material 4 was made from urethane foam, it is not restricted to this, It can interpose between the indoor and outdoor surface materials 6, and can ensure and maintain the space | interval of indoor and outdoor surface materials. Any material can be used. For example, it is possible to further improve the fire resistance by using a paper honeycomb, a core material in which aluminum hydroxide is infiltrated into the paper honeycomb, a core material in which the paper honeycomb is filled with glass wool, or the like. Further, the core material 4 is not limited to a panel shape, and may be a member in which a metal channel material or the like is formed in a frame shape, for example.

  In addition, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
