  The reinforcing member main body 61 includes an inner plate portion 61a as a facing portion facing the inner surface material 3, an outer plate portion 61b as a facing portion facing the outer surface material 4, an inner plate portion 61a and an outer plate portion 61b. It is formed by the connection board part 61c which connects the edge of the door bottom side, and follows a prospective direction. That is, the lock reinforcing member 6 has a groove shape in which the connecting plate portion 61c forms the bottom. The connecting plate portion 61c has extending pieces 61d that extend from the inner plate portion 61a and the outer plate portion 61b both in the vertical direction of the entrance door 1a. Further, the surface facing the inner surface material 3 of the inner plate portion 61a and the surface facing the outer surface material 4 of the outer plate portion 61b are respectively along the edge on the door end side and the edge on the door bottom side. Thus, a thermally expandable graphite 10 is provided as a heated foam material that is heated and foamed.

  The electric lock 5 is inserted into the hole 2b from the outside of the aggregate 2 so that the dead bolt 5a is located on the door end side, and the electric lock 5 is brought into contact with the expected surface 2a of the aggregate 2 The flange portion 5d is fixed with screws. At this time, the cable 5b for supplying electric power to the electric lock 5 is inserted through the hole 2b before the lock body 5c.

  The fixing member 62 includes a main body portion 62a disposed so as to close between the upper edge portions and the lower edge portions of the inner plate portion 61a and the outer plate portion 61b in a state where the entrance door 1a is attached. The aggregate side fixing portion 62b extending from the edge of the main body portion 62a to the opposite side of the electric lock 5 along the aggregate 2 from the edge of the aggregate 2 side, and the door bottom of the main body portion 62a And a reinforcing material side fixing portion 62c that extends from the side edge to the electric lock 5 side so as to be substantially parallel to the aggregate side fixing portion 62b and is fixed to the lock reinforcing member 6.

  The main body 62a has a lock in which the electric lock 5 is accommodated in the same direction as the aggregate-side fixing portion 62b by cutting and raising a part thereof from the center in the width direction of the entrance door 1a to the reinforcing-material-side fixing portion 62c. The reinforcing member 6 is provided with a protruding piece 62d protruding outward, and a through-hole 62e is formed at a portion where the protruding piece 62d is bent and raised. The cable 5b of the electric lock 5 is inserted through the through hole 62e.

  The protruding piece 62d protrudes so as to form a through-direction surface 62f along the direction through which the through-hole 62e passes, and the thermally expandable graphite 10 is provided on the through-direction surface 62f on the through-hole 62e side. . More specifically, the thermally expansive graphite 10 is provided on the through-direction surface 62f on the through-hole 62e side of the protruding piece 62d bent and raised so as to be substantially perpendicular to the main body 62a provided with the through-hole 62e. It has been.

  When the reinforcing member main body 61 is fixed to the aggregate 2 by the fixing member 62, the lock main body portion 5c of the electric lock 5 includes the aggregate 2, the inner plate portion 61a, the outer plate portion 61b, and the connecting plate portion 61c. The dead bolt 5a of the electric lock 5 and the flange portion 5d of the lock body 5c protrude from the hole 2b, and are accommodated in one through-hole 62e. Cable 5b is inserted. The protruding piece 62 d provided on the main body 62 a of the fixing member 62 and the thermally expandable graphite 10 provided on the protruding piece 62 d are opposed to the extending piece 61 d of the lock reinforcing member 6.

  When the front door 1a of the present embodiment is exposed to a flame due to a fire or the like, the lock reinforcing member 6 is also heated by heating the inner surface material 3 and the outer surface material 4, and the protruding piece of the fixing member 62 The thermally expandable graphite 10 provided at 62d is foamed. At this time, the thermally expandable graphite 10 is provided on the through-direction surface 62f on the through-hole 62e side of the protruding piece 62d that is substantially perpendicular to the main body 62a provided with the through-hole 62e. By expanding the graphite 10 along the main body 62a, the expanded thermally expandable graphite 10 expands so as to block the through-hole 62e. For this reason, even when the entrance door 1a is further heated, even if the fire is ignited from the heat insulating material 7 provided between the inner surface material 3 and the outer surface material 4, the flame is generated in the lock reinforcing member 6 and in the hole. Since it does not ignite outside the entrance door 1a through 2b, it is possible to provide the joinery 1 provided with the entrance door 1a which is provided with the electric lock 5 and is difficult to catch fire outside.

  Further, since the lock reinforcing member 6 includes the reinforcing member main body 61 and the fixing member 62, each member can have a simple shape and can be easily manufactured.

  Further, since the protruding piece 62d having the through-direction surface 62f provided with the thermally expandable graphite 10 protrudes toward the outside of the lock reinforcing member 6 on the opposite side to the electric lock 5, it is fixed to the electric lock 5. The thermally expandable graphite 10 is foamed on the opposite side of the member 62. For this reason, the thermally expandable graphite 10 can be foamed away from the electric lock 5 to block the flame at a position further away from the electric lock 5.

  Moreover, since the through-hole 62e has penetrated along the in-plane direction of the inner surface material 3 and the outer surface material 4, the cable 5b of the electric lock 5 protrudes in the out-of-plane direction of the inner surface material 3 and the outer surface material 4. It is possible to arrange | position along the in-plane direction of the inner surface material 3 and the outer surface material 4, without making it. For this reason, it is possible to store the cable 5b neatly without increasing the thickness of the entrance door 1a.

  Further, when the entrance door 1a is heated by being exposed to a flame, a gap is generated between the inner surface material 3 and the outer surface material 4 and the aggregate 2 located at a portion where the hole 2b is provided in the aggregate 2. Although there is a possibility, the front door 1a of the present embodiment is provided with the thermally expandable graphite 10 between the inner plate portion 61a and the outer plate portion 61b of the reinforcing member main body 61 and the inner surface material 3 and the outer surface material 4. Therefore, even if the inner surface material 3 and the outer surface material 4 are warped due to heating, the thermally expansive graphite 10 causes the space between the inner plate portion 61a and the inner surface material 3 and between the outer plate portion 61b and the outer surface material 4. It is possible to prevent a gap from occurring between the two.

  In the embodiment described above, the example in which the through-hole 62e through which the cable 5b of the electric lock 5 is inserted is provided in the fixing member 62 that fixes the reinforcing member main body 61 is not limited thereto. A through hole through which the cable is inserted is not provided in any of the fixing member and the fixing member, and the through hole may be formed when the reinforcing member body is fixed to the aggregate by the fixing member.

  Moreover, in the said embodiment, although the example which comprised the lock reinforcement member 6 by the reinforcement member main body 61 and the fixing member 62 was demonstrated, the lock reinforcement member may be formed with the single member.

In the said embodiment, although the door was made into the entrance door 1a, it is not restricted to this, The metal frame surrounding four rounds, such as a door attached to places other than an entrance, and a sliding door, and a metal inner surface material As long as the door body includes an outer surface material and an electric lock.
