  In this case, an existing door frame is used to install a new door in an exchangeable manner, and for example, as seen in the cover method, the opening of the new frame is prevented as much as possible and the door is airtight as a renovated door. So, it is possible to obtain a simple renovated door that ensures door performance such as heat insulation and soundproofing. For example, it is a so-called public corporation using a press door that was built around the 1950s to 1950s and generally called the KJ door. It is possible to replace the doors of houses and private condominiums with high-performance doors. In this case, by installing a new indoor frame on the existing door frame, it will be opened as much as possible even though it is thin. The opening of the existing door frame cannot be used as it is, the installation work of the indoor new frame is still complicated, and a considerable amount of on-site work remains, and the groove shape is formed at the end of the indoor new frame. By arranging the protrusion, this protrudes from the door contact surface of the existing door frame to the outside of the room, and as a result, the prospect of the new door is limited. As a result, the new door protrudes from the existing door frame to the outside of the room. , The problem that the thickness of the new door becomes a special dimension remains.

  The present invention has been made in view of such circumstances, and the problem to be solved is that the existing door can be installed in the existing door frame from which the existing door has been removed and installed as easily as possible. The purpose of the present invention is to provide a renovated door using an existing door frame that can assure natural airtightness and simplify the field work as much as possible.

  In accordance with the above-mentioned problems, the present invention replaces an existing door with an existing door frame from which the existing door has been removed, and the new door is provided with an airtight material, so that, for example, the hinge of the existing door is used for the new door. The door can be refurbished with a simple work to replace it, and the airtight material of the new door is as close to the door contact surface of the existing door frame as possible. Cover this at the end and install it with good appearance so that the airtightness between these door contact surfaces and the outer peripheral edge of the new door can be secured stably and reliably. This prevents the size of the outdoor frame from narrowing from the door contact surface of the existing door frame, and even if a new door with a standard thickness is used, it fits well in the existing door frame and is remodeled with a good appearance It can be used as a door That is, according to the present invention, the existing door frame is removed by replacing the existing door with the existing door frame by removing the existing door and installing the new door on the existing door frame. The new door is a double-sided flush door and has a rectangular strip on the outer periphery of the indoor-side finding surface so that it is flush with the finding surface. A series of concave grooves are arranged along the door shape so as to define an outer peripheral end portion, and the airtight material is formed into an L shape with respect to the cushion portion, the thin base portion having the cushion portion, and the thin base portion. And the fitting leg of the double-sided flush door is inserted into the recessed groove of the double-sided flash door, and the cushion part is inserted into the outer peripheral end of the outer side of the recessed groove. It is arranged overhanging on the part side and A renovated door using an existing door frame, wherein the outer peripheral end of the door is continuously covered and surrounded by an action portion so that an airtight material can be freely brought into contact with the door contact surface of the existing door frame. Therefore, this is the gist of the invention and used as means for solving the above problems.

  Since the present invention is configured as described above, the present invention replaces the existing door with the existing door frame from which the existing door has been removed, and the new door is provided with an airtight material. The door can be refurbished with a simple operation of replacing the hinge with that for the new door, and the airtight material of the new door is as close as possible to the door contact surface of the existing door frame. Cover the outer peripheral edge of the indoor-side finding surface and install it with a good appearance so that the airtightness between these door contact surfaces and the outer peripheral edge of the new door can be ensured stably and reliably. By installing the new door on the side of the new door, it is possible to prevent the size of the outdoor frame from narrowing from the door contact surface of the existing door frame, and this fits well into the existing door frame even if a standard thickness new door is used. Existing door frame with good appearance It is possible to provide a refurbished door.

  Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. A is a refurbished door, and the refurbished door A is installed by replacing the existing door 3 on the existing door frame 1 after removing the existing door. The airtight material 15 installed on the new door 3 is brought into contact with the existing door frame 1 to ensure the airtightness between the existing door frame 1 and the new door 3. At this time, the new door 3 This is a double-sided flash door, and is formed in a rectangular strip on the outer periphery of the indoor-side finding surface so as to continuously form the outer peripheral end portion 9 that is coplanar with the finding surface, following the door shape. The recessed groove 6 is disposed and the airtight member 15 is fitted to the cushion portion 17, the thin base portion 16 having the cushion portion 17, and the fitting leg portion facing the outdoor side so as to form an L shape with respect to the thin base portion 16. 18 with both of the above The fitting leg portion 18 of the airtight material 15 is fitted into the recessed groove 6 of the flash door, and the cushion portion 17 is arranged in a protruding manner on the outer peripheral end 9 side outside the recessed groove 6. By continuously covering and surrounding the outer peripheral edge 9 of the door, the airtight material 15 can be brought into contact with the door contact surface 2 of the existing door frame 1.

  That is, the refurbished door A is constructed in the 1950s to the 50s, for example, so that the doors of so-called public housing and private condominiums using press doors generally called KJ doors are replaced with high-performance doors. In this case, the new door 3 is a double-sided flush door that ensures heat insulation and soundproofing performance, and this is replaced with the existing door of the press door in the KJ door. For example, the existing door is removed and the associated door is removed. Remove the existing hinge of the existing door, install the new hinge for the new door on the existing door frame 1, and use the remaining existing door frame 1 as much as possible in the state where the residents of each door lived. The door renovation work can be completed in a short time without generating noise.

  The new door 3, that is, the double-sided flush door, is formed by, for example, forming a central frame 4 formed by fastening the upper, lower, left and right frame members 5 in a U-shaped cross section so as to define the outer shape of the door, An outdoor panel 11 stretched on the middle bone 4 so as to cover the attached surface and the prospective surface, and an indoor panel 13 stretched on the middle bone 4 so as to cover the indoor-side found surface; The above-described series of recessed grooves 6 are arranged in the middle of the center-side frame 4 in the width direction of the indoor-side finding surface of the upper, lower, left and right frame members 5 and the indoor side panel 13 is exposed so as to expose the recessed grooves 6 to the indoor side. It is assumed that the airtight member 15 is installed by fitting the fitting leg 18 into the exposed recessed groove 6 so that the structure of the new double-sided flash door can be simplified as much as possible. A series of air-tight materials are securely and continuously installed on the outer edge of the door. The airtightness are as shall be secured effectively and appropriately.

  In this example, the upper, lower, left, and right frame members 5 are formed into a U-shaped cross-section by bending a steel plate, for example, by pressing or roll homing, and are displaced from the center, for example, to the outer peripheral side of the indoor-side finding surface. In addition, a rectangular narrow strip is formed on the outer periphery of the indoor-side finding surface, and an outer peripheral end portion 9 that is coplanar with the indoor-side finding surface is partitioned and formed in a series of longitudinal grooves so as to open to the indoor side. Steel having the same cross-section and different length formed with a concave groove 6 is used, and the frame member 5 is cut at both ends in the longitudinal direction at an angle of 45 degrees, and the cut surfaces are abutted. The butt portion is fastened and joined by, for example, welding, and a rectangular frame is applied as the middle bone 4. Between the upper, lower, left and right frame members 5 in the frame, reinforcement is performed by laying and arranging so that a number of reinforcing frame members 10 are interposed at appropriate positions. The rectangular frame and the reinforcing frame member 10 installed on the rectangular frame are in the form of a lattice having excellent rigidity. At this time, the reinforcing frame member 10 is commonly used in the shape of a U-shaped cross section before the formation of the recessed groove 6 of the upper, lower, left and right frame members 5, for example, a length corresponding to the thickness provided by notching at both ends in the longitudinal direction. The front end protrusions are inserted into and engaged with slits formed through the upper, lower, left, and right frame members 5, and in the case of the reinforcing frame members 10, the front end tongue pieces are provided with the same notch processing at both longitudinal ends. Is inserted into a slit provided in the other side and bent, and is joined within the above-mentioned rectangular frame that has been fastened and joined as easily as possible with sufficient strength.

  At this time, the recessed grooves 6 arranged in the upper, lower, left, and right frame members 5 having the U-shaped cross section are formed into, for example, a U-shaped cross section, and the opening thereof is somewhat narrowed in this example. The opposing opposing wall on one outer peripheral side is an inclined wall 7 in the groove inner direction, and the other inner peripheral wall is a vertical wall 8, thereby fitting leg portions in the airtight material 15 fitted and arranged in the recessed groove 6 described later. It is designed to prevent 18 from coming off.

  In the present embodiment, the lattice 4 is filled with an appropriate heat insulating material 21 such as glass wool or foamed resin block, and the inside and outside of the inside are covered with the outdoor panel 11 and the indoor panel 13. Thus, for example, a double-sided flash door having a thickness of 36 mm, which is expected to be a standard, is used. At this time, the outdoor panel 11 has an outer surface of the central bone 4 and a peripheral bent portion thereof. The interior side panel 13 covers the interior side face so as to cover the interior side face, and the recessed grooves 6 of the upper, lower, left and right frame members 5 in the middle bone 4 are directly exposed to the indoor side. I have to do it.

  The outdoor side panel 11 and the indoor side panel 13 of this example are rectangular in the outdoor side panel 11 so as to cover the middle bone 4 by using a steel panel such as a PVC steel plate or a baked steel plate having a decorative surface. A flat outdoor exterior surface is provided so that it forms a shallow box shape with the prospective surface bent at the ends of the four sides to the indoor side. The indoor panel 13 has a slightly smaller area. In the same manner, it has a rectangular flat plate-like indoor side finding surface.

  In this example, the outdoor panel 11 is provided with a narrow folded strip 12 that is bent from the door-side expected surface to the indoor-side facing surface, and the folded strip 12 is disposed on the middle bone. The outer peripheral edge 9 on the door end side 4 is overlap-coated to cover the edges of the door-side expected surface and the indoor-side finding surface. The indoor side edge of the door-side expected surface is prevented from being exposed and the appearance is impaired, and the appearance is good.

  That is, the outdoor side panel 11 of this example is formed by, for example, folding the front end of the expected surface bent from the outdoor side finding surface to the back side so as to prevent the edge from being exposed. On the other hand, it is assumed that the end of the door has been treated, but especially on the door-side expected surface, the tip is further bent toward the indoor-side finding surface so that the door-side expected surface has a groove shape. A narrow folded strip 12 is formed and arranged on the outside panel 11 so that the outdoor panel 11 has a three-sided upper side and a vertical side from the surface to be viewed, and is a prospective surface subjected to end treatment. The outer peripheral edge formed by forming the covering of the inner bone 4 by the outdoor panel 11 with the folded strip 12 in the upper, lower, left, and right frame members 5 by providing the folded strip 12 on the prospective surface on the side. The portion 9 is superposed so that the door side expected surface and the indoor side facing surface Edge and those coated Chukotsu 4 so as to cover the, it is so to eliminate the bad appearance of exposed said edges at door leading side.

  Further, in this example, the indoor side panel 13 is formed with a bent edge portion 14 bent outward at the outer peripheral end portion 9, and is positioned inside the fitting leg portion 18 of the airtight material 15. Assuming that the bent edge portion 14 is inserted into the recessed groove 6 of the middle bone 4, the frame material of the middle bone or the edge of the recessed groove is exposed on the indoor side face of the double-sided flash door of the new door. Is prevented from being damaged, and has a good appearance.

  That is, the indoor side panel 13 of this example is provided with a bent edge portion 14 whose four sides are bent to the outdoor side in addition to the rectangular flat plate-like indoor side finding surface. The cover 4 of the middle bone 4 is inserted into the recessed groove 6 along the inner peripheral wall forming the vertical wall 8 of the recessed groove 6 in the upper, lower, left and right frame members 5. Thus, the appearance defect in which the edge of the frame member 5 of the middle bone 4 or the recessed groove 6 is exposed on the indoor side finding surface is eliminated.

  For example, the outdoor side panel 11 and the indoor side panel 13 are arranged so that the outdoor side panel 11 is turned upside down with respect to the middle bone 4, and the middle bone 4 coated with an adhesive is placed thereon. The interior side panel 13 is placed and fixed to each other by adhesive bonding, and the cover is fixed as a double-sided flash door having panels on both the front and back sides of the middle bone 4.

  At this time, in this example, the thin folded strip 12 is arranged on the outdoor panel 11 so that the central bone 4 is placed on the outdoor panel 11 and the door end is inserted into the lower surface of the folded strip 12. This is done by gradual insertion mounting in which the suspender side is lowered and the folded strip 12 does not block the recessed groove 6 of the door frame material 5 of the middle bone 4 by the insertion mounting. The outer peripheral end portion 9 is covered. In this example, in order to perform insertion mounting, the folded strip 12 has a width of, for example, a narrow width of about 5 mm or less, and in this example, for example, about 4 mm. Thus, the width of the folded strip 12 is Is more than about 5 mm, for example, in the new door 3 having the thickness of 36 mm, for example, it is easy to mount the insertion of the central bone 4 having a thickness of about 35 mm, which is about 1.5 mm thinner than the thickness of the panel on both sides. The frame material 5 of the middle bone 4 is wider than necessary to prevent the tip of the folded strip 12 from being caught in the recessed groove 6 and prevent the cost from increasing. is there.

  In addition, by placing the bent edge portion 14 on the indoor side panel 13, the indoor side panel 13 is placed on the middle bone 4 inserted and placed on the outdoor side panel 11 so that the four bent edge portions 14 are arranged in series. It is assumed that it is placed in a horizontal drop shape so as to be inserted into the recessed groove 6 that is continuous with the groove 6 and is mounted. At this time, the width of the bent edge portion 14 is made as narrow as that of the folded strip 12. Particularly, the depth of the recessed groove 6 is smaller than about 1 cm, for example, about 1 to 2 mm or more, and is about 5 mm in this example.

  The double-sided flash door covered with the outdoor panel 11 and the indoor panel 13 and exposing the recessed groove 6 in this way is provided in the existing door frame 1 in order to ensure airtightness with the existing door frame 1. The airtight material 15 that can be contacted is installed on the door contact surface 2 of the existing door. In this example, the airtight material 15 includes a thin base portion 16 made of a hard resin and made as thin as possible, A soft resin hollow cushion portion 17 bulging integrally toward the indoor side of the surface of the base portion, and a hard resin short projecting toward the outdoor side of the back surface so as to bend the base portion 16 into an L shape. A leg base 19 having a size, and the leg base 19 and the fitting leg 18 are formed so as to be inclined inwardly toward the interior side toward the locating surface on both sides of the leg base 19. By simultaneously extruding multiple fins 20 of soft resin The airtight material 15 is inserted into the recessed groove 6 continuously connected to the upper, lower, left and right frame members 5 in the middle bone 4 so as to press-fit the fitting legs 18 thereof. By pressing the plurality of soft resin fins 20 against the opposing wall of the recessed groove 6, in this example, the inclined wall 7 and the vertical wall 8, the cushion portion 17 is placed outside the recessed groove 6. In this example, the outer peripheral end 9 including the folded strip 12 on the door end side is arranged in an overhanging manner, and the outer peripheral end 9 of the door is continuously covered with a good appearance by the cushion portion 17. In a state where the double-side flash door of the new door 3 is suspended and installed on the door frame 1, the cushion portion 17 is disposed so as to be close to and face the door contact surface 2 of the existing door frame 1. 2 and the outer peripheral edge 9 of the new door 3 are stable and reliable. It is then adapted to secure the.

  Since the airtight material 15 is installed at the outer peripheral end 9 of the double-sided flash door of the new door 3 in this way, the airtight material 15 is constantly pressed between the door 3 and the door contact surface 2 to form a recessed groove. 6 is pressed inward so that the fitting leg 18 that is generally fitted does not come off from the recessed groove 6, but the airtight material 15 is partially removed due to mischief of the child such as pulling out the airtight material 15. In this example, the airtight member 15 is installed in the present example by fitting the fitting leg 18 together with the thin-walled base 16 at the outer peripheral end 9, in this example. On the front side, the folded strip 12 is adhered with an adhesive applied to one of the folded strips 12 to perform stable and reliable fixing.

  The double-sided flash door is refurbished in this example by installing the air-tight material 15 and further manufacturing the finished product, including the installation of other parts such as the door scope (not shown), lever handle and door knob. By installing the new hinge on the existing door frame 1 from which the existing hinge has been removed, so as to be replaced with the existing door at the site of renovation, The door renovation is completed with the doors of public housing and private apartments as renovated doors A. At this time, if the existing door frame 1 has paint film peeling etc., it will hinder painting or partial repairs. Although it is not a thing, even if this is included, it will be necessary to perform on-site construction for a long time in a common space such as the corridor at the front door, noise, dust, vibration, etc. In addition, the double-sided flush door is manufactured as a high-performance door that ensures the above-mentioned insulation and soundproofing performance by pressing a steel plate and installing a mailbox on it. For press doors that are not expected to have high performance and soundproofing, it is possible to ensure the same heat insulation and soundproofing of the entrance as in newly built condominiums. At this time, the new hinge can be made to be a further earthquake-resistant door if it has earthquake resistance, for example, using a hinge called an anti-seismic hinge or if the dimension setting is for earthquake resistance. Yes, the door function can be improved to increase the value of the house.

  Although the illustrated example is as described above, in implementing the present invention, the double-sided flush door of the new door, its inner frame, the outdoor panel, the indoor panel, the recessed groove, the airtight material, its cushion part, the thin base The specific structure, shape, material, relationship between them, addition to these, etc., such as the section, fitting leg, folding strip of the outdoor panel used in the above example, bent edge of the indoor panel, etc. Various forms can be used as long as they do not contradict the gist, and it is not necessary to limit to the examples illustrated and described above.
