  The existing door frame 1 is made of a steel upper frame 1a, lower frame 1b, vertical frame 1c, 1d of a hanging base and a door end, and a rectangular opening formed by fusing both ends in the longitudinal direction. At this time, the upper frame 1a, the lower frame 1b, the vertical frames 1c, and 1d of the existing door frame 1 have the same cross-sectional shape, respectively, and the indoor side expected surface 13, the outdoor side expected surface 14, and a door stop between them. Anchor fixing in which the surface 15 is provided with an S-shaped cross section, and the indoor-side finding surface 16 and the outdoor-side finding surface 17 facing the inside and outside of the room are bent in the opposite direction. It is fixed to a concrete frame, in particular, its reinforcing bars (both not shown) by anchors (not shown) arranged at predetermined intervals. At this time, the indoor side expected surface 13 and the outdoor side expected surface 14 can be found in the door Arranged so that the surface 15 faces the indoor side, facing the indoor side Thus, the indoor side expected surface 13 is arranged outside the surface, and the outdoor side expected surface 14 is arranged inside the surface, whereby the indoor side opening 11 partitioned by the indoor side expected surface 13 is made a wide area opening, The outdoor-side opening 12 defined by the outdoor-side expected surface 14 has a narrow opening area. In the present example, the indoor-side opening 11 and the outdoor-side opening 12 are each one of the width of the door-holding surface 15. This is a relatively small wide / narrow area difference with a vertical and horizontal length of twice as long as.

  In the existing door frame 1 configured in this manner, an existing door main body is disposed so as to be accommodated in the indoor opening 11 having the wide opening area, and is suspended and supported by a hinge (not shown) on the suspension side. The existing door body can be opened and closed freely toward the indoor side.

  The refurbished door A has the existing door frame 1 that has been removed from the existing door main body, for example, may be subjected to repairs such as painting as necessary, but it is used as it is, and instead of the existing door main body, The new door main body 2 is disposed on the existing door frame 1 so as to be accommodated in the outdoor opening 12 having the narrow opening area, and is hung and supported using a new hinge 3 such as an earthquake-resistant hinge. The new door main body 2 is configured to be openable to the outside, that is, to be openable and closable toward the common space in front of the entrance in the apartment house.

  The new door body 2 is a steel soundproof and heat insulating door in which front and back door surface plates 22 are arranged on both sides of the aggregate 21 and a soundproof and heat insulating material 23, for example, a honeycomb material is interposed between the surface plates 22. At this time, the new door main body 2 is provided with an airtight material 4 on the upper and lower sides and the outer periphery of the door tip on the outdoor side, and on the outer peripheral side of the suspension base on the indoor side. By rotating each airtight member 4 against each of the outdoor side finding surfaces 17 on the three sides of the existing door frame 1 and the doorside finding surface 15 on the one side, the airtightness as the modified door A is secured. There is something to do.

  In this example, the airtight member 4 is provided on the rear surface of the receiving frame 41 that is arranged in a protruding manner in the out-of-plane direction from the finding surface of the new door body 2. Alternatively, it is disposed so as to project toward the door stop finding surface 15, and a newly formed door body 2 of the existing door frame 1 is provided with an on-site processing through-hole in the outdoor outside expected surface 14 located on the door end side, It is assumed that a lock fitting 51 of the lock 5 of the new door main body 2 is installed in the through hole.

  That is, the receiving frame 41 of this example includes a fixed piece, an upright piece standing upright from the fixed piece, and an airtight material receiving piece protruding in an out-of-plane direction from the upright piece. In this example, the fixed piece is fixed to the above-mentioned outdoor outer periphery 3 sides and indoor-side outer periphery 1 side of the new door body, such as screwing, bonding, etc. The airtight material receiving piece 4 is taken out to the outdoor side through the door, and faces the outdoor-side or door-holding surface of the existing door frame. It is possible to make a free contact. The receiving frame 41 can be formed of an extrusion-molded material having a receiving groove of an airtight material such as aluminum or synthetic resin. However, the illustrated frame has a structure obtained by processing a steel plate, for example. An extrusion-molded support material 42 having a receiving groove is screwed to the rear surface of the airtight material receiving piece of the receiving frame 41, for example, from the front, bonded, or in this example, screwed 8, and through the support material 42. It is assumed that the airtight material 4 is installed in the receiving frame 41.

  Therefore, the new door main body 2 is effectively and reliably sealed with the existing door frame 1 by closing the new door main body 2 without the airtight material 4 installed on the new door main body 2 obstructing the opening and closing of the outer door. It is possible to ensure the property.

  At this time, the airtight material 4 which is in the upper frame 1a of the existing door frame 1 and is in contact with the outdoor-side finding surface 17 of the upper frame 1a is a receiving material 41, and in this example, the above-mentioned extrusion molding support material. By arranging an inclined ridge 43 inclined upward at the end of 42 on the side of the outdoor side finding surface 17 and covering the gap between the receiving material 41 and the outdoor side finding surface 17 by the arrangement of the airtight material 3 Infiltration of rainwater is prevented. In the figure, reference numeral 44 designates a fixing piece arranged on the upper side of the airtight material 4 of the outdoor side finding surface 17 by screwing, bonding, or fixing in this example with the screw 8, and the connecting piece is connected from the airtight material 4.

Therefore, the new door main body 2 is provided with a lock 5 to be locked using the lock fitting 51, and in this example, the lock 5 in the new door main body 2 is a push-pull lock.

  Since the outdoor-side expected surface 14 of the existing door frame 1 is arranged to be displaced inward in the plane by the width of the door-holding surface 15 as compared with the indoor-side expected surface 13, the outdoor-side expected surface 14. Even if mortar is filled on the back side, the distance to the concrete frame, that is, the penetration depth can be secured large. , It is possible to receive and arrange a box-like strike in a sickle lock that locks by locking out a locking sickle from the outdoor surface, and therefore includes a lever handle lock using the strike, the push-pull lock, etc. Various locks can be installed.

  Further, in the refurbished door A of this example, a part or all of the indoor side expected surface 13 of the existing door frame 1 is excluded, and in this example, the suspension door and lower frame 2 of the new door main body 2 are excluded. The decorative member 7 corresponding to the width of the door-to-door look-up surface 15 is arranged on the indoor-side look-up surface 13 on the side, and the step between the room-side look-up surface 13 and the outdoor-side look-up surface 14 is eliminated or reduced. At this time, the decorative member 7 of this example is used as a door guard or a door chain at the door end of the new door main body 2, or as a security bracket installation base of the door guard 6 in this example.

  In this example, the decorative member 7 has a C-shaped cross section and is made of steel having the same length as the upper frame 1a of the existing door frame 1 and the vertical frame 1c of the hanging base, and the upper frame 1a in the existing door frame 1 is used. Further, the outdoor side expected surface 14 of the vertical frame 1c of the suspension base is extended toward the indoor side, and particularly fixed to the indoor side expected surface 13 by screws 8 directed toward the indoor side expected surface 13 so as to extend flush with each other. As a result of eliminating the difference in level between the outside expected surface 14 and the exterior door 14, the interior appearance of the refurbished door A is improved, while the airtightness of the hanging door in the new door body 2 is secured, and the lower frame 1 b The danger of passage due to the formation of a step with the floor surface on the indoor side of the new door main body 2 is prevented.

  The base for installing the security member 7 of the decorative member 7 at the door of the new door main body 2 is in this example, and the base for installing the receiving bracket 61 of the door guard 6 installed at the door of the indoor side finding surface 13 of the new door main body 2 is shown. The fitting 61 of the door guard 6 is fixed on the prospective surface of the decorative member 7 with a screw 8 facing the indoor-side prospective surface of the vertical frame 1d of the door, and is engaged with the main body of the door guard 6. It is possible to join.

In this example, a part or all of the receiving frame 41 is fixed to the prospective surface of the new door main body 2 with screws 8 so that the new door main body 2 An example in which the airtight material 4 in the present example is arranged in an overhanging direction from the finding surface is shown. The fixed piece is formed in an L-shaped cross section, the fixed piece is directed to the end of each new door main body 2, and the projecting piece directed toward the indoor side is brought into contact with each prospective surface of the new door main body 2. The fixing piece is fixed to the new door main body 2 by fixing the fixing piece with screws, bonding, in this example, the screws 8 toward the aggregate 21.

  In this example, by arranging the receiving frame 41 so as to protrude from the prospective surface of the new door main body 2 to the outdoor side, the fixing part 41 is prevented from being exposed to the new door main body 2; In this example in which the appearance is good and the fixing piece is fixed with screws 8, the exposure of the screw 8 used for fixing, particularly the screw head, to the finding surface is prevented.

  FIG. 7 and FIG. 8 show still another example. In this example, it is arranged at the base of the new door main body 2 and can be brought into contact with the door-holding surface of the existing door frame 1. Instead of the airtight material, an example is shown in which the airtight material 4 that can be contacted to the prospective surface of the new door main body 2 is arranged on the door-holding surface 15. In this example, the new door main body is shown. The airtightness of the suspension base can be ensured without disposing the airtight material 4 on the suspension base.

  In this example, the airtight material is formed by arranging the airtight material 4 on a receiving material 41 having a U-shaped cross section, and receiving material on the stepped portions of the door-holding surface 15 and the indoor side expected surface 13 of the existing door frame 1. The two airtight members 41 are in contact with each other, and the airtight member 4 can be brought into contact with the newly installed door body 2, for example, the end portion on the interior side of the prospecting surface or the end portion of the facing surface at a fixed position. At this time, the receiving member 41 is fixed by fixing the bottom wall thereof with screws, bonding, in this example, by fixing the screws 8 to the indoor side expected surface 14 of the existing door frame 1. .

  Since the remainder of FIGS. 5, 6, 7, and 8 is the same as that in the above example, the same reference numerals are given and redundant descriptions are omitted.

  In the refurbished door A, the new door body 2 can be arranged in the outdoor opening 12 of the existing door frame 1 to open and close the door and to secure the airtightness that was missing in the existing door. The new door main body 2 is opened and closed between the vertical frame 1c of the hanging base and the hanging end of the new door main body 2. The difference in the rotation trajectory of the end is about 1 to 2 mm in the outdoor opening 12, that is, about 1 mm when the thickness of the new door body 2 is 36 mm as in the modified door A in FIGS. 6 and FIG. 7, when it is 40 mm, it can be about 2 mm. Therefore, the width of the new door main body 2 is about several mm with respect to the width of the outdoor opening 12 of the existing door frame 1 with a margin, For example, it should be as wide as possible by reducing it by 4-5 mm. Kill. What is necessary is just to set the height of this new door main body 2 so that the upper and lower ends may not contact the upper frame 1a and lower frame 1b of the existing door frame 1 when the new door main body 2 is opened and closed.
