In addition, the conventional door frame (cover frame, refurbishment frame) is attached to all of the existing upper and lower frames (existing upper and lower frames) and the existing left and right frames (existing vertical frames). It tends to cause a decrease in efficiency.

  Furthermore, the conventional door frame (cover frame, refurbishment frame) is substantially composed of a single member. The existing upper and lower frames (existing upper and lower frames) using existing bolts and nuts are fixed. Since it is attached to the left and right frames (existing vertical frames), the fixture may be visible from the outside, which may impair the overall appearance of the housing.

  In addition, the conventional door frame (cover frame, repair frame), the existing upper and lower frame (existing upper and lower frame), and the existing left and right frame (existing vertical frame) are fixed in contact with each other between the metal members. Since it is often fixed, it is difficult to ensure water tightness in a state where there is no gap completely. Therefore, when rainwater or the like is applied to the vicinity of the door frame (cover frame or repair frame) at the opening of the housing, the rainwater or the like easily enters the housing. In other words, rainwater or the like enters the door frame (cover frame, repair frame), not only the door frame (cover frame, repair frame), but also the existing upper and lower frames (existing upper and lower frames), the existing left and right frames.

The other end surface 2b (or the other end surface 3b of the cover frame 3) may be drained.

  As described above, by providing the drainage gap S between the existing frame 9 and the other end surface 2b of the cover base material 2 (and the other end surface 3b of the cover frame body 3), rainwater or the like can be removed from the cover base material. 2 and the length of the cover base material 2 and the cover frame 3 even when entering the space formed by the cover frame 3 (and the space formed by the existing frame 6, the cover base material 2, and the cover frame 3). It is possible to drain rainwater or the like from the drainage gap S by flowing out from the other end surface 2b of the cover base material 2 or the other end surface 3b of the cover frame 3 by flowing rainwater along the direction. Thus, it is possible to prevent rainwater and the like from entering the enclosure.

  Next, a door replacement method will be described mainly with reference to FIGS. 5 to 13 with a focus on a method of attaching the door frame 1 according to the present invention.

  An airtight for door contact (not shown) already attached to the support portions (door contact portions of the existing frames) 63, 63 extending from the connecting portion 62 at the end of the existing frames 6, 6 on the indoor side. Remove the material. When removing the airtight material, the watertight material 64 is newly affixed to the support portion (the door contact portion of the existing frame) 63, or the support portion (the door contact portion of the existing frame) is the end surface of the cover base material 2. The airtight material is completely removed in consideration of the contact with 28a. And the watertight material 64 which covers the opening part 63a of a cross-sectional substantially U-shaped part is affixed on the support part (door stopper part of the existing frame) 63 which removed the airtight material. As shown in FIG. 5, the watertight member 64 covers the opening 63 a having a substantially U-shaped cross section, and is a support portion (existing frame) formed along the longitudinal direction of the opening 10 of the housing (not shown). The door 63) covers the opening 63a of the substantially U-shaped section.

(Positioning process between the existing frame 6 and the cover base material 2)
Next, one end face 2a of the cover base material 2 and one end face 3a of the cover frame body 3 are opposed to the existing frame 8, and for example, in this example, one end of the cover base material 2 is opposed to the end face 8a of the existing frame 8. The end surface 2a is brought into contact (contacted) (see FIG. 4). At the same time, the back surface portion 25 of the cover base material 2 is brought into contact with (attached to) the mounting surface 61 of the existing frame 6 along the longitudinal direction of the existing frame 6. As shown in FIG. 6B, the cover base material 2 has a plurality of small holes 25a drilled in advance. The size of the small hole portion 25a is not particularly limited, but it is sufficient that the existing frames 6 and 6 can be confirmed from the small hole portions 25a of the cover base materials 2 and 2.

  Then, in the position corresponding to the small hole portion 25a on the mounting surface 61 of the existing frame 6 that can be confirmed from the small hole portion 25a previously punched in the cover base material 2, as shown in FIG. Further, using the drill 100, small holes 25 b and 65 having a diameter larger than the small hole 25 a are drilled in the back surface 25 of the cover base material 2 and the mounting surface 61 of the existing frame 6. That is, by drilling the cover base material 2 and the existing frame 6 in accordance with the small hole portion 25a provided in the back surface portion 25 of the cover base material 2, the small hole portion 25a of the cover base material 2 is expanded in diameter. The small hole portion 25 b is provided, and the small hole portion 65 is provided on the mounting surface 61 of the existing frame 6. In this example, the diameter of the small hole portion 25b of the cover base material 2 to be drilled using the drill 100 and the small hole portion 65 of the mounting surface 61 of the existing frame 6 is about 4.5 mm. It is not limited, and the diameter may be determined by a waterproof fixture. As described above, the positioning for fixing the cover base material 2 to the existing frame 6 is performed based on the back surface portion 25 of the cover base material 2.

  In addition, the rectangular shape of the dotted line shown in FIG.6 (b) has shown the attachment position of the hinge 11, and this part is avoided in the case of drilling. That is, as shown in FIG. 6 (b), a hole is drilled so as to sandwich the attachment position of the hinge 11 (position indicated by the dotted line), and a load is applied at the time of opening and closing the door 5 by attaching a fixture in the future. It is possible to increase the strength of the hinge 11 relative to the hinge 11. Then, after drilling, the cover base material 2 is removed from the existing frames 6 and 8, and the diameter of the small hole portion 65 is increased by a drill or the like (not shown) in order to increase the diameter of the small hole portion 65 of the existing frame 6. In this example, the diameter of the small hole portion 65 is about 8 mm by a drill or the like (not shown), but the diameter is not limited to about 8 mm, and the diameter may be determined by a waterproof fixture.

(Step of fixing the cover base material 2 to the existing frame 6)
Next, a waterproof fixture is inserted into the small-diameter portion 65 having an enlarged diameter provided on the mounting surface 61 of the existing frame 6. Specifically, as shown in FIG. 7, a rubber nut 15 having a sealing effect is inserted into the small-diameter portion 65 whose diameter has been increased. The use of the rubber nut 15 in this example is shown in FIG. As shown in FIG. 9A, the rubber nut 15 inserted into the small hole portion 65 is held in the small hole portion 65 by the ring-shaped portion 15 b having a diameter larger than that of the small hole portion 65.

  Then, based on the existing frame 8, in this example, one end surface 2a of the cover base material 2 is brought into contact (contacted) with the end surface 8a of the existing frame 8, and the back surface portion 25 of the cover base material 2 is set to the existing frame 8. 6 and 6 are brought into contact with (attached to) the attachment surfaces 61 and 61. As a result, as shown in FIG. 9B, the small hole portion of the cover base material 2 is placed on the small hole portion 65 of the existing frame 6 via the ring-shaped portion 15 b larger than the small hole portion 25 b of the cover base material 2. 25b overlap. As shown in FIGS. 7 and 9 (b), the bolt 17 is inserted from the small hole portion 25 b of the cover base material 2 in the arrow direction shown in FIG. 7 and screwed into the nut portion 15 c of the rubber nut 15.

  As shown in FIG. 9 (c), when the bolt 17 and the nut portion 15 c of the rubber nut 15 are screwed together by the driver 101, the ring-shaped portion 15 b is installed on the back surface portion 25 of the cover base material 2. Since it is sandwiched and pressed between the attachment surfaces 61 of the frame 6, it is adsorbed around the small holes 25 b and 65. At the same time, the nut portion 15c moves toward the small hole portion 65, and the rubber portion 15d covering the nut portion 15c also moves toward the small hole portion 65 to form the ring-shaped portion 15a.

  As a result, as shown in FIG. 9 (c), the nut-shaped head portion 17 a and the ring-shaped portion 15 b tighten tightly around the small hole portion 25 b, and the two-stage ring-shaped portion having a diameter larger than the small hole portion 65. The periphery of the small hole portion 65 is tightened by 15a and 15b. For this reason, the degree of close contact of the ring-shaped portions 15a and 15b with the small hole portions 25b and 65 is increased. That is, since the ring-shaped portions 15a and 15b are made of rubber, water tightness around the small hole portions 25b and 65 is secured. Accordingly, it is possible to prevent rainwater and the like from entering the existing frame 6 from the small hole portions 25b and 65.

  Further, when the screw 17 is screwed into the nut portion 15 c of the rubber nut 15 by the driver 101 and screwed, the ring shape of the rubber nut 15 is formed on the back surface portion 25 of the cover base material 2 and the mounting surface 61 of the existing frame 6. The part 15 b is sandwiched and protrudes from the back part 25 of the cover base material 2. However, since the projecting portion 25c is formed on the back surface portion 25, even if the back surface portion 25 of the cover base material 2 is brought into contact (contacted) with the mounting surface 61 of the existing frame 6, the cover base material 2 The back surface portion 25 is parallel to the mounting surface 61 of the existing frame 6. In this way, one end surface 2a of the cover base material 2 abuts (contacts) with the end surface 8a of the existing frame 8, and the back surface portion 25 of the cover base material 2 contacts the mounting surfaces 61 and 61 of the existing frames 6 and 6. The cover base material 2 is fixed to the existing frames 6, 6, and 8 in a state of contact (contact).

  In this example, an example in which the rubber nut 15 is inserted into the small hole portion of the mounting surface 61 of the existing frame 6 is shown as an example, but the rubber nut 15 is not particularly limited to be used. Other than the rubber nut 15, for example, a watertight washer can be used. Specifically, a watertight washer is passed through the bolt 17 where the bolt screw is provided, and is screwed with the bolt 17 and a nut disposed in the existing frame 6, so that the back surface portion 25 of the cover base material 2 and the existing one are installed. A watertight washer is sandwiched between the mounting surface 61 of the frame 6 and watertightness is ensured. As another example, for example, a waterproof member is provided on the head of the bolt, and when the bolt and the nut are completely screwed together, the waterproof member on the head of the bolt is crushed and the back portion 25 The watertightness is ensured by covering the small holes 25a.

(Process of forming a drainage gap between the cover base material 2 and the existing frame 9)
As described above, one end surface 2a of the cover base material 2 is opposed to the existing frame 8, and in this example, the one end surface 2a of the cover base material 2 is brought into contact with the end surface 8a of the existing frame 8 (contact). The back surface portion 25 of the cover base material 2 is brought into contact with (attached to) the mounting surface 61 of the existing frame 6 along the longitudinal direction of the existing frame 6, and the back surface portion 25 of the cover base material 2 is brought into contact with the back surface portion 25 of the cover base material 2. The small hole portion 25b provided and the small hole portion 65 provided on the mounting surface 61 of the existing frame 6 are fixed in an overlapping state, and along the longitudinal direction of the existing frame 6 to which the cover base material 2 is fixed. A drainage gap S is formed between the other end surface 2 b of the cover base material 2 and the existing frame 9.

(Step of temporarily fixing the cover frame to the cover base material 2)
Then, on the mounting surface 61 of the existing frame 6 covers the cover base material 2 by the cover frame body 3, by engaging the cover frame 3 to cover the base member 2, cover frame to cover the base member 2 3 is temporarily fixed. Specifically, the cover frame 3 is moved (slid) on the mounting surface 61 of the existing frame 6, and the gap V formed by the recessed portion 26 of the cover base material 2 and the mounting surface 61 of the existing frame 6. The cover frame body 3 is temporarily fixed to the cover base material 2 by incorporating the back surface portion 31 of the cover frame body 3 into the cover base material 2 and overlapping the joint portion 37 of the cover frame body 3 with the joint portion 29 b of the cover base material 2.

  That is, first, the back surface portion 31 of the cover frame body 3 is brought into contact with the mounting surface 61 of the existing frame 6. At the time of contact, as shown in FIG. 10, the back surface portion 31 of the cover frame body 3 is set along the attachment surface 61 of the existing frame 6. In this state, the back surface portion 31 is moved along the attachment surface 61, and reaches the gap V formed by the attachment surface 61 and the inclined surface 26 b of the cover base material 2. As shown in FIG. 10, the inclined surface 26 b with respect to the back surface portion 31 is in an open state so that it easily enters the gap V formed by the recessed portion 26 of the cover base material 2 and the mounting surface 61. Become.

  Then, the cover frame body 3 is moved on the mounting surface 61 of the existing frame 6 along the direction of the arrow shown in FIG. 10, so that the recess 26 of the cover base material 2 and the mounting surface 61 of the existing frame 6 are formed. By incorporating the back surface portion 31 of the cover frame body 3 into the gap V, the joint portion 37 of the cover frame body 3 moves on the flat surface portion 27a of the cover base material 2 and moves to the flat surface portion 29c and the flat surface portion 29a. The bent part 33 of the frame 3 moves to the flat part 27a. At this time, the end portion 27 of the cover base material 2 is sandwiched between the bent portion 33 and the back surface portion 31 of the cover frame body 3 so that the cover frame body 3 is temporarily fixed to the cover base material 2 (attached) State). At the same time, the joint portion 37 of the cover frame 3 and the joint portion 29b of the cover base material 2 face each other. Further, the recess 2c of the cover base material 2 and the recess 3c of the cover frame 3 are overlapped to form a space. In this space, when the hinge 11 for suspending the door 5 is attached, a fixture for attaching the hinge 11 is incorporated.

(Step of fixing the cover frame 3 to the cover base material 2 and attaching the cover frame 3 to the existing frame 6)
In such a temporarily fixed state, the flat surface portion 27 a of the cover base material 2 is in contact with the bent portion 33 of the cover frame body 3, and the flat plate portion 29 c and the flat plate portion 29 a of the cover base material 2 are covered with the cover frame body 3. In contact with the joint 37. Therefore, in this example, the joint part 29b of the cover base material 2 and the joint part 37 of the cover frame 3 are opposed to each other without being in contact with each other. In this manner, with the joint portion 29b and the joint portion 37 facing each other, the tapping screw 13 is used to pass through and fix the joint portion 29b and the joint portion 37 as shown in FIG. As described above, the cover frame 3 is fixed to the cover base material 2, and the cover frame 3 is attached to the existing frame 6. In this example, the joint portion 29b of the cover base material 2 and the joint portion 37 of the cover frame body 3 are not in contact, but the joint portion 29b of the cover base material 2 and the joint portion 37 of the cover frame body 3 It is also possible to fix them with the tapping screw 13 in contact with each other.

  Although not shown in FIG. 12, the connection between the joint portion 29 b and the joint portion 37 using the tapping screw 13 is performed along the longitudinal direction of the cover base material 2 and the cover frame body 3. And the space | interval of the tapping screws 13 used for connection is determined in consideration of the strength of the cover base material 2 and the cover frame 3 and the like. Thus, by connecting the joint part 29b and the joint part 37, the cover frame body 3 can be fixed to the cover base material 2, and to the existing frame 6 of the cover base material 2 to which the cover frame body 3 is fixed. Fixing is completed.

  In this example, when the cover base material 2 to which the cover frame body 3 is fixed is fixed to the existing frame 6 along the longitudinal direction of the existing frame 6, the existing frame 6 to which the cover base material 2 is fixed. A drainage gap S is also formed between the other end surface 3 b of the cover frame body 3 and the existing frame 9 along the longitudinal direction. However, it is not necessary to form the same drain gap S between the other end surface 2b of the cover base material 2 and the other end surface 3b of the cover frame 3 and the existing frame 9 as in this example, and the cover base material 2 and the size of the drainage gap between the other end surface 2b of the cover frame 3 and the size of the drainage gap between the other end surface 3b of the cover frame 3 and the existing frame 9 are different. Also good. That is, either one of the drainage gaps may be larger or smaller than the other drainage gap.

  In this example, before fixing the cover frame body 3 to the cover base material 2, the sheath portion 39c1 is incorporated in the door contact portion 39c of the cover frame body 3, and the door contact rubber 39c2 is incorporated in the sheath portion 39c1. It is also possible to incorporate the sheath portion 39c1 into the door stop portion 39c after the cover frame 3 is incorporated into the cover base material 2, and incorporate the door stop rubber 39c2 into the sheath portion 39c1.

  As for the existing frame 8, as shown in FIG. 13, a sheath portion 81b is incorporated into a door stop portion 81a extending from the connecting portion 81, and a watertight material 81c, which is a door stopper rubber, is incorporated into this sheath portion 81b. As shown in FIG. 13, a sheath portion 91 b is incorporated in a door stop portion 91 a extending from the connecting portion 91, and a watertight material 91 c that is a door contact rubber is incorporated in the sheath portion 91 b. As described above, the cover base material 2 and the cover frame body 3 are fixed to the existing frames 6 and 6, and the sheath portions 81 b and 91 b and the watertight materials 81 c and 91 c are incorporated into the door contact portions 81 a and 91 a of the existing frames 8 and 9. The construction which attaches the door 5 to the existing frames 6, 6, 8, 9 of the opening part 10 of a housing is completed by this. It is also possible to previously incorporate the watertight materials 81c and 91c into the sheath portions 81b and 91b.

  Finally, the hinge 11 is placed at the position where the hinge 11 (not shown) in the longitudinal direction of the cover base material 2 and the cover frame 3 is attached, and the space formed by the cover base material 2 and the cover frame 3 is used. No. 11 is attached and the door 5 is suspended as shown in FIG. Adjustment of the lock etc. of the door 5 is performed and the installation of the door 5 is completed.

  Next, a characteristic mechanism of the door 5 suspended in the opening 10 of the housing using the door frame 1 according to the present invention will be briefly described.

  The door 5 suspended in the opening 10 of the housing by refurbishment or the like performs operations such as opening and closing similarly to the door before renovation or the like. However, when rainwater or the like falls on the door 5 (opening 10 of the housing), the door frame 1 of the present invention functions as a watertight device for the door frame 1. Specifically, when rainwater or the like falls on the door 5, not only rainwater or the like falls on the entire surface of the door 5, but also the existing frames 6, 6, 8 and 9 provided around the door 5, the cover base material 2, Rain water or the like is also applied to the cover frame 3. As described above, when rainwater or the like is applied to the entire surface of the opening 10 of the casing, the rainwater or the like enters the gap between the openings 10 of the casing.

  In such a case, in particular, rainwater or the like easily enters the metal touch part (contact part between the metal members). In this example, the cover base material 2, the cover frame 3, and the existing frames 6, 8, and 9 are metal members. As shown in FIG. 14, the contact position between the existing frame 6 and the cover frame 3 is a metal. Since it is a touch part, a clearance is easily formed, and intrusion of rainwater or the like is unavoidable as compared with a position in contact with a metal member and a waterproof fixture (rubber nut 15).

  That is, when rainwater or the like falls on the door 5 (opening 10 of the housing), rainwater or the like enters the contact position between the existing frame 6 and the cover frame 3 from the direction of arrow A. Rainwater or the like that has entered the contact position between the existing frame 6 and the cover frame body 3 flows in the direction of arrow B, and the small holes 25b of the cover base material 2 into which the rubber nuts 15 are inserted and the existing frame 6 are small. It flows toward the hole 65.

  Even if the rubber nut 15 flows into the small hole portion 25b of the cover base material 2 into which the rubber nut 15 is inserted and the small hole portion 65 of the existing frame 6, the rubber nut 15 seals the small hole portions 25b and 65 here. Therefore, water tightness is secured, and basically, rainwater or the like does not enter the existing frame 6. However, as shown in FIG. 14, by flowing in the direction of the arrow B, between the tip of the back surface portion 31 of the cover frame 3 and the surface pressing portion 26 a of the cover base material 2 in the middle of the small holes 25 b and 65. Rain water or the like may enter the gap R. In such a case, rainwater or the like further flows along the direction of arrow C and flows into the gap T formed by the end portion 32 of the cover frame body 3 and the end portion 27 of the cover base material 2, and further in the direction of arrow D. Along the metal touch portion between the flat plate portion 27 a and the bent portion 33, the air flows into the space formed by the cover base material 2 and the cover frame material 3. Further, rainwater or the like flows into the space formed by the cover base material 2 and the cover frame material 3 from around the attachment screw 19 of the hinge 11.

  As described above, the gap R between the existing frame 6 and the cover base material 2 and the cover frame body 3, the rainwater flowing into the space formed in the cover base material 2 and the cover frame body 3 are shown in FIG. As shown, it flows in the direction of the existing frame 9 along the direction of arrow E. That is, rainwater or the like flows through the existing frame 6, the cover base material 2, and the cover frame body 3 along the longitudinal direction of the existing frame 6, the cover base material 2, and the cover frame body 3. Since the drainage space S is provided between the other end surface 2b of the cover base material 2 (and the other end surface 3b of the cover frame 3) and the existing frame 9, rainwater or the like can be removed from the cover base material 2 and the cover. It flows out from the frame 3, flows along the direction of arrow F, and is drained from the existing frame 6, the cover base material 2, and the cover frame 3.

  The door frame 1 according to the present invention is not limited to a configuration in which the opening 10 of the housing is not narrowed when the opening 10 of the housing is simply repaired. As rainwater or the like falls on the opening 10 of the housing, the watertightness of the rainwater or the like is secured, and the rainwater or the like is drained to the outside through the door frame 1 as a watertight device. It also has functions. Therefore, the door frame 1 according to the present invention can be regarded as a watertight device for the door frame.
