Description

  The present invention relates to a door.

  2. Description of the Related Art Conventionally, doors that can improve heat shielding performance have been proposed as doors provided at entrances and the like. For example, Patent Document 1 discloses a door including a door body having glass wool, a steel plate, and a refractory material. Specifically, among the side surfaces of glass wool, the door body is covered with steel plates on the outdoor side surface, upper side surface, lower side surface, left side surface, and right side surface, and the indoor side surface is made of refractory material.

  However, in the conventional door described in Patent Document 1, as described above, the interior side surface of the refractory material is exposed to the outside. For example, the refractory material is formed of a material that is difficult to paint. In this case, it is difficult to achieve design uniformity between the door and the members provided around it, and it is difficult to maintain the side surface of the fireproof material so as not to be damaged. There was a possibility of deteriorating the design of the door. Moreover, in the conventional door described in the above-mentioned Patent Document 2, as described above, since the stone kou layer is accommodated inside the door, for example, one of the pair of surface materials is heated by the heat of the fire. In this case, the entire door is warped and deformed by a temperature difference generated between the pair of surface materials, so that there is a gap between the door and the frame provided around the opening that is opened and closed by the door. Since the heat of the fire may be transmitted through this gap, it may be difficult to maintain the heat shielding performance of the door.

  The present invention is to solve the above-described problems in the prior art, and an object of the present invention is to provide a door that can maintain the design and heat shielding performance of the door.

  In order to solve the above-described problems and achieve the object, the door according to claim 1 is a door body that opens and closes an opening of a building, and is a support member and one of two main side surfaces of the door body. 1st surface material which comprises one, Comprising: The 1st surface material which covers the substantially whole of the side surface of the one side of the prospective direction in the said supporting member, and comprises either one of the two main side surfaces of the said door body A door having a second surface material that covers at least the entire side surface of the other side in the prospective direction of the support member, the first surface of the door body. At least one of the substantially entire first outer surface that is the outer side surface in the prospective direction of the surface material and the substantially entire second outer surface that is the outer side surface in the prospective direction of the second surface material of the door body. A heat shield for covering one side, and the heat shield in the heat shield Covering substantially the entire write direction of the outer side surface, and a, a decorative plate having a non-flammable.

  The door according to claim 2 is the door according to claim 1, wherein substantially the entire first outer surface of the first surface material of the door body and the second surface material of the door body are the second surface material. The heat shielding means was provided on the first surface material and the second surface material, respectively, so that substantially the entire outer surface of the two outer surfaces was covered with the heat shielding means.

  The door according to claim 3 is the door according to claim 1 or 2, wherein the decorative plate is provided so as not to contact the first surface material of the door body and the second surface material of the door body. It was.

  The door according to claim 4 is the door according to any one of claims 1 to 3, wherein thermal expansion is provided in at least one of the door body, the heat shielding means, or the decorative board. When a fire is generated around the door body in the fully closed state where the opening is fully closed by the door body, the thermal expansion refractory member is expanded by the heat of the fire, A thermal expansion fireproof member for closing a gap formed between the door body, the heat shielding means, or the decorative plate and a frame body provided at the periphery of the opening is provided.

Since the heat shield means for covering is provided, the heat shield means can suppress the heat of the fire generated on either side of the door body in the expected direction from being conducted to the door body. Thereby, even when the above-mentioned fire occurs, it becomes difficult to produce a temperature difference between the first surface material and the second surface material, so that the entire door can be prevented from warping and deforming. Therefore, compared with the case where no heat shield means is provided, the warp deformation of the door causes a gap between the door and the frame provided around the opening, and thus the fire is transmitted through the gap. It is possible to avoid the heat of the heat being transmitted in the expected direction. In addition, since it has a nonflammable decorative plate that covers substantially the entire outer side surface in the prospective direction of the heat shield means, the entire outer side surface in the prospective direction of the heat shield means is made unexposed from the outside. Compared to the case where no decorative plate is provided, for example, the heat shield means can be prevented from being damaged by receiving an external force, and the makeup is easier to paint than the heat shield means. Since the heat shield means is covered with the plate, it is easy to achieve design uniformity between the door and the members provided around the door. From the above, it becomes possible to maintain the design and heat shielding performance of the door as compared with the prior art.

  According to the door of the second aspect, substantially the entire first outer surface of the first surface material of the door body and substantially the entire second outer surface of the second surface material of the door body are covered by the heat shielding means. As described above, since the heat shielding means is provided on the first surface material and the second surface material, respectively, substantially the entire first outer surface of the first surface material of the door body, or the second surface material of the door body. It is possible to further maintain the design and heat shielding performance of the door as compared with the case where only one of the entire second outer surface is covered with the heat shielding means.

  According to the door of Claim 3, since the decorative board was provided so that it might not contact with the 1st surface material of a door body, and the 2nd surface material of a door body, the fire which arose on the decorative board side rather than the door body Can be suppressed from being transmitted to the first surface material of the door body and the second surface material of the door body through the decorative plate, and the heat shielding performance of the door can be further improved.

  According to the door of Claim 4, it is a thermal expansion fireproof member provided in at least any one of a door body, a heat insulation means, or a decorative board, Comprising: A fire is carried out around a door body in a fully closed state. When this occurs, the thermal expansion refractory member expands with the heat of the fire, so that the thermal expansion refractory for closing the gap formed between the door body, the heat shielding means, or the decorative plate and the frame body Since the member is provided, it is possible to suppress the heat of the fire from being transmitted through the gap, and it is possible to further improve the heat shielding performance of the door.

These first thermal expansion refractory member 81 and second thermal expansion refractory member 82 are, for example, known thermal expansion refractory members that foam when heated at a predetermined temperature (specifically, a temperature of 150 ° C. to 250 ° C.). (Specifically, it is configured using FiBlock (registered trademark) or the like). The first thermal expansion refractory member 81 is fixed to the door body 20, the outdoor decorative plate 62, or the indoor decorative plate 72 with double-sided tape, an adhesive, or the like, and the second thermal expansion refractory member 82. Is fixed to the door frame 30 with a double-sided tape, an adhesive, or the like.

  Here, with respect to the installation positions of the first thermal expansion refractory member 81 and the second thermal expansion refractory member 82, the heat of the fire generated on either the outdoor side or the indoor side of the room is on the outdoor side or the indoor side of the room. As long as it is possible to suppress the transmission to either one, it can be set arbitrarily. In the first embodiment, the first thermal expansion refractory member 81 or the second thermal expansion refractory member 82 includes the door body interference avoidance space DS1 and its vicinity position, the door body interference avoidance space DS2 and its vicinity position, and door body interference avoidance. It is provided in the space DS3 and its vicinity position, and the door body interference avoidance space DS4 and its vicinity position.

  Among these, regarding the specific installation position with respect to the door body interference avoidance space DS1 and its vicinity position, as shown in FIG. Of the side surfaces on the indoor side, the door body interference avoidance space DS1 and the portion corresponding to the vicinity thereof (except the portion corresponding to the latch described later and the vicinity thereof), and the door side of the indoor side decorative plate 72 It is provided on the side. Further, the second thermal expansion refractory member 82 has a side surface corresponding to the door body interference avoidance space DS1 in the door end side vertical frame 11 of the frame body 10 (however, the portion corresponding to the dead bolt receiver and the latch receiver and the vicinity thereof are Except). As for the specific installation position with respect to the door body interference avoidance space DS2 and the vicinity thereof, as shown in FIG. 3, the first thermal expansion refractory member 81 is a room in the outdoor surface material 41 of the door body 20. Of the outer side surface, the portion corresponding to the hinge interference avoidance space HS, the portion corresponding to the door body interference avoidance space DS2 and the vicinity thereof among the indoor side surfaces of the room inner surface material 42 of the door body 20, And it is provided in the side surface by the side of the door bottom of the indoor side decorative board 72. FIG. In addition, regarding the specific installation position with respect to the door body interference avoidance space DS3 and the vicinity thereof, as shown in FIG. 4, the first thermal expansion refractory member 81 is a room in the indoor surface material 42 of the door body 20. Among the inner side surfaces, the door body interference avoiding space DS3 and a portion corresponding to the vicinity thereof, the upper surface of the outdoor decorative plate 62, and the upper surface of the indoor decorative plate 72 are provided. As for the specific installation position with respect to the door body interference avoidance space DS4 and the vicinity thereof, as shown in FIG. 4, the first thermal expansion refractory member 81 has a lower side surface of the indoor side surface material 42 of the door body 20, And provided on the lower surface of the outdoor decorative plate 62. In addition, about the setting of the installation area | region of the 1st thermal expansion refractory member 81 or the 2nd thermal expansion refractory member 82 provided in each side surface mentioned above, in Embodiment 1, the 1st thermal expansion refractory member 81 or the 2nd thermal expansion Since it may vary depending on the expansion rate, thickness, etc. of the refractory member 82, it is set by experimentation.

With such an installation position, when the heat of the fire is generated on either the outdoor side or the indoor side of the room, the first thermal expansion fire-resistant member 81 or the second thermal expansion fire-resistant member 82 causes the door body 20 and the frame. A gap formed between the body 10 and the body 10 can be effectively blocked.

  Due to the heat insulation structure between the door body 20 and the frame body 10 as described above, when fire heat is generated on either the outdoor side or the indoor side of the room, the heat is expanded by the heat of the fire. The first thermal expansion refractory member 81 and the second thermal expansion refractory member 82 cause the heat of the fire to pass through a gap formed between the door body 20 and the frame body 10, or on the outdoor side or the indoor side of the room. Therefore, the heat shielding performance of the door 1 can be further improved.

(Configuration-door action)
The operation of the door 1 configured as described above will be described.

  For example, in the fully closed state in which the opening is fully closed by the door body 20, when a fire occurs outside the room (evacuation passage), the outdoor decorative panel 62 is heated by the heat of the fire. In this case, when a part of the heat of the fire tries to be transmitted from the outdoor decorative plate 62 to the door body 20, the outdoor heat shield 61 causes the outdoor decorative plate 62 and the door body 20 to be connected to each other. The heat conduction is suppressed, and the outdoor decorative plate 62 is provided so as not to come into contact with the outdoor surface material 41, so that the heat conduction between the outdoor decorative plate 62 and the door body 20 is further increased. It is suppressed. Further, if another part of the heat of the fire tries to be conducted to the indoor side of the room through the gap formed between the door body 20 and the frame body 10, the first heat is caused by the heat of the fire. The expansion of the thermal expansion refractory member 81 and the second thermal expansion refractory member 82 causes the gap to be closed by the expanded first thermal expansion refractory member 81 and second thermal expansion refractory member 82, and thus the heat of the fire Other part of the conduction is suppressed. From the above, it is possible to suppress the heat of the fire from being transmitted to the door body 20 via the outdoor decorative plate 62 or being transmitted to the indoor side of the room through the gap. It becomes possible to suppress that the inside of is heated rapidly.

  For example, when a fire occurs in the room in the fully closed state, the indoor decorative plate 72 is heated by the heat of the fire. In this case, when a part of the heat of the fire tries to be conducted from the indoor decorative plate 72 to the door body 20, the indoor heat insulating portion 71 causes the indoor decorative plate 72 and the door body 20 to be connected to each other. Since heat conduction is suppressed and the indoor side decorative plate 72 is provided so as not to contact the indoor side surface material 42, heat conduction between the outdoor side decorative plate 62 and the door body 20 is further increased. It is suppressed. In addition, when another part of the heat of the fire tries to conduct to the outdoor side of the room through a gap formed between the door body 20 and the frame body 10, the first heat is caused by the heat of the fire. The expansion of the thermal expansion refractory member 81 and the second thermal expansion refractory member 82 causes the gap to be closed by the expanded first thermal expansion refractory member 81 and second thermal expansion refractory member 82, and thus the heat of the fire Other part of the conduction is suppressed. From the above, it is possible to suppress the heat of the fire from being transmitted to the door body 20 via the indoor decorative plate 72 or being transmitted to the outdoor side of the room via the gap. Can be prevented from evacuating through the evacuation passage.

Next, the inserted rotation shaft is rotatably fixed to a fixing member (not shown) provided on each of the outdoor decorative plate 62 and the indoor decorative plate 72. And the handle main-body part 21a of the handle 21 is fixed with respect to each of the front-end part and rear-end part of this rotating shaft.

  The latch is for maintaining the door body 20 in the fully closed position regardless of whether the locking device is locked. The latch is connected to the handle 21 through an interlocking mechanism (not shown) provided inside the door body 20, and the latch is interlocked with the operation of the handle 21 by the user, on the door side of the door body 20. Can be taken in and out from the side. Thus, in the fully closed state, the door 20 can be maintained at the fully closed position by engaging the latch with the latch receiver provided on the door-end side vertical frame 11.

  The locking device is a device for locking the door body 20. This locking device is configured to include a dead bolt (not shown). Specifically, when the user performs a key operation from the front of the door body 20, the dead bolt is attached to the door end side of the door body 20. The door body 20 can be locked by being able to be taken in and out from the side surface and locking the dead bolt to a dead bolt receiver provided in the door-end side vertical frame 11 in the fully closed state.

  The door closer 22 is for automatically closing the door body 20 at a safe speed when the door body 20 is opened, and as the door body 20 is rotated, the door body 20 is opened to a predetermined position or more. It is for restricting that it will be in the state of being. The door closer 22 can rotate the arm portion 22a of the door closer 22 in the front-rear direction, and the force when the door 20 is opened with the door 20 in the open position is used as a restoring force. While using, a sudden return can be suppressed by a damper (not shown) housed in the main body 22b of the door closer 22. For example, first, the arm portion 22a of the door closer 22 is fixed to the upper horizontal frame 13 of the frame 10 with a fixing tool. Next, a mounting hole (not shown) formed in the indoor decorative panel 72, a mounting hole (not shown) formed in the indoor heat shield 71, and a mounting hole formed in the indoor surface material 42 of the door body 20 (Not shown), and a body portion of the door closer 22 through an attachment hole (not shown) formed in the upper lateral force bone 33 of the door body 20 (or a liner (not shown) provided inside the door body 20). A connecting member (not shown) for connecting 22b to the door body 20 is fixed to the upper lateral force bone 33 by a fixing tool. And the main-body part 22b of the door closer 22 is fixed with a fixing tool with respect to a connection member.
