[0003] [Patent Document 1] Japanese Patent Application Publication No. 05-222878 Summary of the Invention [Problem to be solved by the invention]

[0004] In the hinge of Patent Document 1, the housing 5 is welded to the door frame F. However, welding is performed by craftsmen, so the number of craftsmen must be secured. Furthermore, welding generates gases that are harmful to the environment.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a mounting plate and a door structure that can easily secure workers and reduce the environmental burden. [Means for solving the problem]

[0006] The present invention relates to a door structure comprising a door frame, a door that opens and closes relative to the door frame, and door equipment related to the opening and closing of the door relative to the door frame. The door equipment is attached to one or both of the door frame and the door, and the attachment plate comprises a mounting surface that is attached to a mounting portion of the door frame or a mounting portion of the door, and an adhesive layer that is provided on the mounting surface and adhered to the mounting portion.

[0007] According to the mounting plate of the present invention, an adhesive layer is provided on the mounting surface, so that mounting to a mounting portion of a door frame or door can be completed simply by adhering the adhesive layer to the mounting portion.

[0008] In the present invention, a positioning protrusion protruding from the mounting surface is provided, and the positioning protrusion is configured to be able to fit into a positioning recess recessed for positioning the mounting portion, and the thickness of the adhesive layer from the mounting surface can be configured to be smaller than the protruding length of the positioning protrusion from the mounting surface.

[0009] According to the mounting plate of the present invention, the thickness of the adhesive layer is smaller than the protruding length of the positioning protrusion. Therefore, even if the positioning protrusion of the mounting plate shifts and approaches the periphery of the positioning recess when fitting it into the positioning recess of the mounting part, the positioning protrusion abuts against the periphery of the positioning recess, and the adhesive layer does not abut against the mounting part. By fitting the positioning protrusion into the positioning recess without abutting the adhesive layer against the mounting part, the work of positioning and attaching the mounting plate to the mounting part is simplified.

[0010] In the present invention, the length of protrusion of the positioning protrusion from the surface of the adhesive layer may be shorter than the depth of the positioning recess of the mounting portion.

[0011] According to the mounting plate of the present invention, the tip of the positioning protrusion does not come into contact with the positioning recess, and the mounting plate is adhered to the mounting portion by the adhesive layer, so that the adhesive layer can provide a secure bond.

[0012] The present invention is a door structure comprising the door frame, the door, the door equipment, and the mounting plate, wherein the mounting plate attached to one or both of the door frame and the door is any of the mounting plates described above. [Effects of the Invention]

[0013] The mounting plate and door structure of the present invention make it easier to secure workers and reduce the environmental burden. [Brief explanation of the drawings]

The hinge 4 and the mounting plate are mechanisms that open and close the door 3 relative to the door frame 2, and will hereinafter be referred to as door opening / closing device A. The door frame 2, door 3, and door opening / closing device A are made of metal unless otherwise specified.

[0017] 1 and 2, the door frame 2 will be described. The door frame 2 has a frame body 5, which is a box-like body that is long in the vertical direction X, long in the horizontal direction Y, and has a thickness direction Z. The frame body 5 has a frame mounting portion 6 that is a mounting portion provided for mounting the door 3.

[0018] Regarding the frame mounting portion 6, a recessed portion of the frame support portion 7, which is a stepped portion, is formed on the side of the frame body 5 where the door 3 is attached, and the frame support portion 7 in the horizontal direction Y serves as the frame mounting portion 6. The frame mounting portion 6 has a front surface 6a and a back surface 6b, and a frame mounting plate 26 (also referred to as a back plate) which is a mounting plate is arranged on the back surface 6b side, and the hinge 4 is arranged on the front surface 6a side. Note that the frame mounting plate 26 which is a mounting plate is arranged on the back surface 6b side, but the arrangement of the frame mounting plate 26 on the frame mounting portion 6 is omitted in the illustration in Figure 1.

[0019] The door 3 will be described with reference to Figures 1 and 2. The door 3 has a door body 9. The door body 9 is a box-like body that is long in the vertical direction X, long in the horizontal direction Y, and has a thickness direction Z. The door body 9 has a door mounting portion 10 that is provided so as to be able to approach the frame support portion 7 by opening and closing.

[0020] Regarding the door mounting portion 10, a pair of parallel door support portions 11, 12 extending in the vertical direction X and extending in the horizontal direction Y with a gap therebetween are formed on the side of the door body 9 that is attached to the frame body 5, and the door mounting portion 10 is formed so as to connect the thickness-wise ends of the door support portions 11, 12. The door mounting portion 10 is a surface portion that extends along the vertical direction X and the horizontal direction Y and has a front surface 10a and a back surface 10b. A door mounting plate 13 (also referred to as a back plate) is disposed on the back surface 10b, and the hinge 4 is disposed on the front surface 10a. Note that the door mounting plate 13 is disposed on the back surface 10b, but the placement of the door mounting plate 13 on the door mounting portion 10 is omitted from the illustration in FIG. 1.

[0021] Of the door opening / closing device A, we will now discuss the hinges 4. The hinges 4 are provided in pairs at the top and bottom, or in three locations at the top, middle, and bottom, so that the door frame 2 and the door 3 can be stably assembled. For this reason, the door opening / closing device A is also provided with the same number of mounting plates as the hinges 4.

[0022] As shown in Figure 1, the hinge 4 has a general configuration and includes a lower blade 14 attached to the frame mounting portion 6 of the frame body 5 and an upper blade 15 attached to the door mounting portion 10 of the door 3.

[0023] The lower blade 14 is also referred to as a shaft-side blade, and includes a lower blade plate 17, a lower tube portion 18, a shaft 19, a ball 20, a sleeve (also referred to as a washer) 16, and a lower star 21. The lower blade 14 is an integral member that includes the shaft 19 as a core rod and the ball 20 in the lower tube portion 18 formed integrally with the lower blade plate 17, the lower star 21 is welded to the underside of the lower tube portion 18, and the sleeve 16 is fixed to the outer periphery of the shaft 19 by crimping. Here, the lower blade plate 17 is a flat plate member fixed to the surface 6a of the frame mounting portion 6. The lower tube portion 18 is an annular member formed at the end of the lower blade plate 17 and having a predetermined distance in the vertical direction X. The shaft 19 is a support shaft member whose lower axial side is inserted and supported in the lower tube portion 18. The ball 20 is a freely rolling ball arranged so that a portion of it is exposed at the tip (upper end) of the shaft 19. The lower star 21 is a stepped member welded to the lower end of the lower tube portion 18 so as to close at the lower open end of the lower tube portion 18. The lower vane plate 17 is formed in the shape of a substantially square rectangular plate, and vane plate screw holes 22 are formed in multiple places on the plate surface. Screws N are threaded into the vane plate screw holes 22 of the lower vane plate 17, and the lower vane plate 17 is fixed to the surface 6a of the frame mounting portion 6.

[0024] The upper blade 15, also referred to as a receiving blade, includes an upper blade plate 23, an upper tube portion 24, and an upper globe star 25. The upper blade plate 23 is a plate-like member fixed to the surface 10a of the door mounting portion 10. The upper tube portion 24 is an annular member formed at the end of the upper blade plate 23 and into which the axially upper side of the shaft 19 is inserted and supported. The upper globe star 25 is a stepped member welded to the upper end of the upper tube portion 24 so as to close the upper open end of the upper tube portion 24. The ball 20 abuts against the bottom of the portion of the upper globe star 25 that is fitted inside the upper tube portion 24. Blade plate screw holes 22 are formed at multiple locations on the plate surface of the upper blade plate 23, and screws N are threaded into the blade plate screw holes 22 to fix the upper blade plate 23 to the surface 10a of the door mounting portion 10.

[0025] The sleeve 16 is an annular member for hiding the joint between the lower tube portion 18 of the lower blade 14 and the upper tube portion 24 of the upper blade 15, and is made of stainless steel.

[0026] Next, we will explain the configuration of the frame mounting plate 26, which is a mounting plate attached to the back surface 6b of the frame mounting portion 6, and the door mounting plate 13, which is a mounting plate attached to the back surface 10b of the door mounting portion 10, of the door opening and closing device A.

[0027] 2 and 3, the frame mounting plate 26 includes a tap portion protection member 27 (trocar cover), a frame side back plate 28, and adhesive layers of frame side back plate double-sided tape 29, 30. The tap portion protection member 27 and the frame side back plate 28 are integrally formed.

[0028] The tap portion protection member 27 is a member that prevents mortar or the like from entering or filling the tap portions of the plate screw holes 32 (described later), and is formed in a rectangular shape that is long in the vertical direction X with an open front side. The frame-side back plate 28 is a rectangular plate-like member that is long in the vertical direction X and has a front surface 28a and a back surface 28b. The frame-side back plate 28 is formed longer in the horizontal direction Y and the vertical direction X than the tap portion protection member 27, and the back surface 28b of the frame-side back plate 28 is fixed to the front end of the tap portion protection member 27. The frame-side back plate 28 has plate screw holes 32 formed in multiple locations in accordance with the slat screw holes 22 formed in multiple locations on the lower slat 17, and the plate screw holes are burred into the back surface 28b of the frame-side back plate 28.

[0029] The frame-side back plate 28 has a positioning protrusion 33. This positioning protrusion 33 fits into a positioning recess 34 formed in the frame mounting part 6 from the thickness direction Z. Returning to the configuration of the frame mounting part 6, the positioning recess 34 is formed in the horizontal center of the frame mounting part 6 so as to correspond to the installation location of the frame mounting plate 26. More specifically, two positioning recesses 34 are formed, one for each installation location, spaced apart in the vertical direction X. Each positioning recess 34 is a hole with a circular cross section that penetrates the frame mounting part 6.

[0030] The positioning protrusions 33 are spaced apart in the vertical direction X along the positioning recesses 34 and are arranged to fit into the positioning recesses 34 in accordance with the shape of the positioning recesses 34. In this embodiment, the positioning protrusions 33 are formed at the horizontal center of the frame-side back plate 28, between the two upper plate screw holes 32 and the two lower plate screw holes 32. As shown in FIG. 5 , the positioning protrusions 33 protrude from the surface 28a of the frame-side back plate 28 and have a cylindrical outer peripheral surface 35 and a curved upper end surface 36 that is disc-shaped and convex at its tip. The positioning protrusions 33 are formed by pressing against the back surface 28b of the frame-side back plate 28.

[0031] The frame-side backing plate double-sided tapes 29, 30 are sheet-shaped and have adhesive front and back surfaces. The back surfaces 29b, 30b of the frame-side backing plate double-sided tapes 29, 30 are arranged on the front surface 28a of the frame-side backing plate 28.

[0032] That is, surface 28a of frame-side backing plate 28 serves as an attachment surface for attaching frame-side backing double-sided tapes 29 and 30. One release paper (not shown) of frame-side backing double-sided tapes 29 and 30 is peeled off and the tapes are adhered to surface 28a, which is the attachment surface.

[0033] The frame-side backing plate double-sided tapes 29, 30 are intended to be attached to the back surface 6b of the frame mounting portion 6, as shown in Fig. 2, after the release paper (not shown) on the other surface has been peeled off. In this case, "intended" means that the manufacturer of the frame mounting plate 26 prepares the frame mounting plate 26 by adhering the frame-side backing plate double-sided tapes 29, 30 to the front surface 28a, which is the mounting surface of the frame-side backing plate 28. The frame mounting plate 26 is then used in the door structure mounting steps (1) and (2) described below.

[0034] In this embodiment, two frame-side backing double-sided tapes 29, 30 are provided equidistantly apart in the vertical direction X, and these frame-side backing double-sided tapes 29, 30 are formed in a rectangular shape. In this case, the rectangular shape means that the lateral width of the frame-side backing double-sided tapes 29, 30 is flush with the lateral width of the frame-side backing plate 28.

[0035] Furthermore, regarding the arrangement of the frame side back plate double-sided tapes 29, 30, the frame side back plate double-sided tapes 29, 30 are arranged so as to cover the upper two plate screw holes 32 and the lower two plate screw holes 32 among the plate screw holes 32.

[0036] The two frame-side backboard double-sided tapes 29, 30 are arranged to avoid at least the periphery of the positioning protrusion 33, and the frame-side backboard double-sided tape 29 is arranged above the upper positioning protrusion 33, while the frame-side backboard double-sided tape 30 is arranged below the lower positioning protrusion 33, with a distance between them. Furthermore, the upper surface 36 of the positioning protrusion 33 is formed to protrude beyond the surfaces 29a, 30a of the frame-side backboard double-sided tapes 29, 30. Specifically, the upper surfaces 36 of the curved ends protrude beyond the surfaces 29a, 30a of the frame-side backboard double-sided tapes 29, 30.

[0037] Each frame side back plate double-sided tape 29, 30, which is arranged to cover two plate screw holes 32, is approximately flush with the frame side back plate 28 in the horizontal direction, as shown in Figure 3(b), and the frame side back plate double-sided tape 29, 30 and the frame side back plate 28 are also approximately flush in the vertical direction.

[0038] In this embodiment, the frame-side backing double-sided tapes 29, 30 are made of acrylic ester resin foam polymer, and the two frame-side backing double-sided tapes 29, 30 have the same thickness. Specifically, as shown in Figure 5, the distance h1 in the thickness direction of the tape from the surface 28a of the frame-side backing plate 28 to the surfaces 29a, 30a of the frame-side backing double-sided tapes 29, 30 is 0.6 mm.

[0039] Here, referring to Figure 5, the relationship between the thickness direction distance h1 of the tape, the protruding length distance h2 of the positioning protrusion 33 from the surface 28a of the frame side backing plate 28, the protruding length distance h3 of the positioning protrusion 33 from the surfaces 29a, 30a of the frame side backing double-sided tape 29, 30, and the depth distance h4 of the positioning recess 34 of the frame mounting portion 6 will be described.

[0040] The thickness direction distance h1 of the tape is set to be smaller than the protrusion length distance h2 of the positioning protrusion 33 from the surface 28a of the frame-side backing plate 28. The protrusion length distance h3 from the surfaces 29a, 30a of the frame-side backing double-sided tapes 29, 30 to the upper surface 36 of the positioning protrusion 33 is set to be shorter than the depth distance h4 of the positioning recess 34 of the frame mounting part 6.

[0041] Furthermore, since the positioning recess 34 is a circular cross-sectional hole that penetrates the frame mounting portion 6, it has no bottom end, and therefore, even when the positioning recess 34 and the positioning protrusion 33 are fitted together, there is nothing to obstruct the upper surface 36 of the positioning protrusion 33.

[0042] Next, the configuration of the door mounting plate 13, which is a mounting plate attached to the rear surface 10b side of the door mounting portion 10, will be described.

[0043] 2 and 4, the door mounting plate 13 includes a door-side back plate 40 and adhesive layers of double-sided tape 37 and 38. The door mounting plate 13 is similar to the frame mounting plate 26 in that it does not include the tap portion protection member 27.

[0044] 4, the door-side back plate 40 is a rectangular plate-like member having a front surface 40a and a back surface 40b, and is long in the vertical direction X. The door-side back plate 40 has plate screw holes 32 formed at multiple locations in accordance with the slat screw holes 22 formed at multiple locations on the upper slat 23, and the plate screw holes 32 are formed by burring the back surface 40b of the door-side back plate 40.

[0045] The door-side back plate 40 has a positioning protrusion 33. This positioning protrusion 33 fits into a positioning recess 34 formed in the door mounting part 10 from the horizontal direction Y. Returning to the configuration of the door mounting part 10, the positioning recess 34 is formed in the center of the door mounting part 10 in the thickness direction so as to correspond to the installation location of the door mounting plate 13. More specifically, two positioning recesses 34 are formed spaced apart in the vertical direction X, one for each installation location. The positioning recesses 34 are holes with a circular cross section that are provided to pass through the door mounting part 10.

[0046] The positioning protrusions 33 are spaced apart in the vertical direction X along the positioning recesses 34 and are arranged to be able to fit into the positioning recesses 34 in accordance with the shape of the positioning recesses 34. In this embodiment, the positioning protrusion 33 is formed at the center in the thickness direction of the door-side back plate 40, between the two upper plate screw holes 32 and the two lower plate screw holes 32.

[0047] 5, the positioning protrusion 33 protrudes from the surface 40a of the door-side back plate 40 and has a cylindrical outer surface 35 and a curved upper end surface 36 that is disc-shaped and convex at the tip. The positioning protrusion 33 is formed by pressing against the back surface 40b of the door-side back plate 40.

[0048] Returning to FIG. 4 , the door-side backing double-sided tapes 37, 38 are sheet-shaped and have a front and back surface that are adhesive to each other. The back surfaces of the door-side backing double-sided tapes 37, 38 are disposed on the front surface 40a of the door-side backing plate 40. That is, the front surface 40a of the door-side backing plate 40 serves as the mounting surface for attaching the door-side backing double-sided tapes 37, 38. One release paper (not shown) of the door-side backing double-sided tapes 37, 38 is peeled off and the tapes are adhered to the front surface 40a, which is the mounting surface. That is, the back surfaces 37b, 38b of the door-side backing double-sided tapes 37, 38 are disposed on the front surface 40a of the door-side backing plate 40.

[0049] The door-side backing double-sided tapes 37, 38 are intended to be attached to the back surface 10b of the door mounting part 10, as shown in Fig. 2, after the release paper (not shown) on the other surface has been peeled off. In this case, "intended" means that the manufacturer of the door mounting plate 13 prepares the door mounting plate 13 by adhering the door-side backing double-sided tapes 37, 38 to the front surface 40a, which is the mounting surface of the door-side backing plate 40. The door mounting plate 13 is then used in the door structure mounting steps (4) and (5) described below.

[0050] 4, in this embodiment, the door-side back panel double-sided tapes 37, 38 are provided equidistantly in the vertical direction X, and the door-side back panel double-sided tapes 37, 38 are formed in a rectangular shape. The rectangular shape in this case means that the width of the door-side back panel double-sided tapes 37, 38 in the lateral direction is flush with the width of the door-side back panel plate 40 in the thickness direction.

[0051] Furthermore, regarding the arrangement of the door side back panel double-sided tapes 37, 38, the door side back panel double-sided tapes 37, 38 are arranged so as to cover the upper two plate screw holes 32 and the lower two plate screw holes 32 among the plate screw holes 32.

[0052] The two door-side back panel double-sided tapes 37, 38 are arranged to avoid at least the periphery of the positioning protrusion 33, and the door-side back panel double-sided tape 37 is arranged above the upper positioning protrusion 33, and the door-side back panel double-sided tape 38 is arranged below the lower positioning protrusion 33, with a distance between them. Furthermore, the upper surface 36 of the positioning protrusion 33 is formed to protrude beyond the surfaces 37a, 38a of the door-side back panel double-sided tapes 37, 38. Specifically, the upper surfaces 36 of the curved ends protrude beyond the surfaces 37a, 38a of the door-side back panel double-sided tapes 37, 38.

[0053] As shown in Figure 4(b), each door-side back panel double-sided tape 37, 38, which is provided to cover the two plate screw holes 32, is approximately flush with the door-side back panel plate 40 in terms of horizontal width, and is also approximately flush with the door-side back panel plate 40 in terms of vertical height.

[0054] In this embodiment, the door-side back panel double-sided tapes 37, 38 are made of acrylic ester resin foam polymer, and the two door-side back panel double-sided tapes 37, 38 have the same thickness. Specifically, referring to Figure 5, the distance h1 in the thickness direction of the tape from the surface 40a of the door-side back panel plate 40 to the surfaces 37a, 38a of the door-side back panel double-sided tapes 37, 38 is 0.6 mm.

[0055] Here, using Figure 5, we will describe the relationship between the thickness direction distance h1 of the tape, the protruding length distance h2 of the positioning protrusion 33 from the surface 40a of the door side back panel plate 40, the protruding length distance h3 of the positioning protrusion 33 from the surfaces 37a, 38a of the door side back panel double-sided tapes 37, 38, and the depth distance h4 of the positioning recess 34 of the door mounting portion 10.

[0056] The thickness direction distance h1 of the tape is set to be smaller than the protrusion length distance h2 of the positioning protrusion 33 from the surface 40a of the door-side back plate 40. The protrusion length distance h3 from the surfaces 37a, 38a of the door-side back plate double-sided tapes 37, 38 to the upper surface 36 of the positioning protrusion 33 is set to be shorter than the depth distance h4 of the positioning recess 34 of the door mounting part 10.

[0057] Furthermore, since the positioning recess 34 is a circular cross-sectional hole that penetrates the door mounting portion 10, it has no bottom end, and therefore, even when the positioning recess 34 and the positioning protrusion 33 are fitted together, there is nothing to obstruct the upper surface 36 of the positioning protrusion 33.

[0058] In the door structure 1, the door 3 is rotatably mounted to the door frame 2 by the door opening / closing device A. That is, a frame mounting plate 26 is installed on the frame mounting portion 6 of the door frame 2, and a door mounting plate 13 is installed on the door mounting portion 10 of the door 3. The frame mounting plate 26 and the lower blade 14 are connected via the frame mounting portion 6, and the door mounting plate 13 and the upper blade 15 are connected via the door mounting portion 10. These door structure mounting steps will be described using an example.

[0059] The door structure installation process includes (1) a tape application process, (2) a frame-side back panel installation process, (3) a lower blade installation process, (4) a tape application process, (5) a door-side back panel installation process, (6) an upper blade installation process, and (7) a door opening and closing process.

[0060] (1) A process of attaching the frame side backing plate double-sided tapes 29, 30 to the frame mounting plate 26. In the tape application step, the release paper on one surface of the frame-side backing plate double-sided tapes 29, 30 is peeled off, and the tapes are applied to the surface (mounting surface) 28a of the frame-side backing plate 28 of the frame mounting plate fixture 26.

[0061] In this tape application process, as described above, the frame-side back plate double-sided tapes 29, 30 are positioned so as to cover the upper two plate screw holes 32 and the lower two plate screw holes 32. In addition, the two frame-side back plate double-sided tapes 29, 30 are positioned so as to avoid the positioning protrusions 33.

[0062] (2) A frame side back plate installation process for installing the frame side back plate 28 on the frame mounting portion 6. The release paper (not shown) is peeled off from the other surfaces 29a, 30a of the frame-side backing plate double-sided tapes 29, 30. Then, in the frame-side backing plate installation process, the positioning protrusions 33 of the frame-side backing plate 28 are fitted into the positioning recesses 34 formed in advance in the frame mounting part 6, and the other surfaces 29a, 30a of the frame-side backing plate double-sided tapes 29, 30 are attached to the frame mounting part 6.

[0063] When the positioning protrusions 33 and the positioning recesses 34 are fitted together, the plate screw holes 32 are set to align with a plurality of through holes (not shown) formed in advance in the frame mounting portion 6. These through holes are also configured to align with the slat screw holes 22 of the lower slat 17.

[0064] The thickness direction distance h1 of the frame-side backing double-sided tapes 29, 30 is set to be smaller than the protrusion length h2 of the positioning protrusion 33 from the surface 28a of the frame-side backing plate 28. Therefore, even if the positioning protrusion 33 of the frame-side backing plate 28 is shifted and approaches the periphery of the positioning recess 34 when the positioning protrusion 33 of the frame-side backing plate 28 is fitted into the positioning recess 34 of the frame mounting part 6, the positioning protrusion 33 abuts against the periphery of the positioning recess 34, and therefore the frame-side backing double-sided tapes 29, 30 do not abut against the frame mounting part 6. Therefore, by fitting the positioning protrusion 33 into the positioning recess 34 without abutting the frame-side backing double-sided tapes 29, 30 against the frame mounting part 6, the work of positioning and attaching the frame-side backing plate 28 to the frame mounting part 6 is simplified.

[0065] Frame side back plate double-sided tape 29, 30 is provided on surface 28a of frame side back plate 28, and surfaces 29a, 30a of frame side back plate double-sided tape 29, 30 are attached to frame mounting portion 6, so that the installation process of frame side back plate 28 at frame mounting portion 6 in door frame 2 can be completed simply by adhering frame side back plate double-sided tape 29, 30 to frame mounting portion 6.

[0066] Furthermore, the protruding length h3 of the positioning protrusion 33 from the surfaces 29a, 30a of the frame-side backing plate double-sided tapes 29, 30 is set to be shorter than the depth h4 of the positioning recess 34 of the frame mounting part 6. With this configuration, the positioning recess 34 is a hole with a circular cross section that is provided to pass through the frame mounting part 6, so that the top surface 36, which is the tip of the positioning protrusion 33, does not come into contact with the positioning recess 34, and the frame-side backing plate 28 is adhered to the frame mounting part 6 with the frame-side backing plate double-sided tapes 29, 30, so that the frame-side backing plate 28 can be firmly adhered to the frame mounting part 6 with the frame-side backing plate double-sided tapes 29, 30. Furthermore, because the tip of the positioning protrusion 33 has a curved surface with a convex tip, it can be easily moved by abutting against the periphery of the positioning recess 34.

[0067] (3) A lower blade installation process for installing the lower blade 14 of the hinge 4 to the frame mounting portion 6. To install the lower blade 14 on the frame mounting portion 6 in the lower blade installation process, the through hole formed in advance in the frame mounting portion 6 is aligned with the blade plate screw hole 22 of the lower blade plate 17, and the screw N is screwed into the blade plate screw hole 22 and into the plate screw hole 32.

[0068] At this time, frame side back plate double-sided tape 29, 30 is attached to the surface 28a of the plate screw hole 32 of the frame side back plate 28, but the frame side back plate double-sided tape 29, 30 is an adhesive layer, and the screw N easily tears the part of the frame side back plate double-sided tape 29, 30 corresponding to the screw, allowing the screw N to be screwed into the plate screw hole 32.

[0069] As a result of the above, the frame mounting plate 26 and the lower blade 14 are installed via the frame mounting portion 6.

[0070] (4) The door side back plate double-sided tapes 37, 38 are attached to the door side back plate 40. In the tape application step, the release paper on one surface of the door-side backing plate double-sided tapes 37, 38 is peeled off, and the tapes are applied to the surface (mounting surface) 40a of the door-side backing plate 40.

[0071] In this tape application process, as described above, the door-side back panel double-sided tapes 37, 38 are positioned so as to cover the upper two plate screw holes 32 and the lower two plate screw holes 32. In addition, the two door-side back panel double-sided tapes 37, 38 are positioned so as to avoid the positioning protrusions 33.

[0072] (5) Door-side back plate installation process for installing the door-side back plate 40 on the door mounting portion 10. The release paper (not shown) is peeled off from the other surfaces 37a, 38a of the door-side back panel double-sided tapes 37, 38. Then, in the door-side back panel installation process, the positioning protrusions 33 of the door-side back panel plate 40 are fitted into the positioning recesses 34 formed in advance in the door mounting portion 10, and the other surfaces 37a, 38a of the door-side back panel double-sided tapes 37, 38 are attached to the door mounting portion 10.

[0073] When the positioning protrusions 33 and the positioning recesses 34 are fitted together, the plate screw holes 32 are set to align with a plurality of through holes (not shown) formed in advance in the door mounting part 10. These through holes are also configured to align with the slat screw holes 22 of the upper slat 23.

[0074] The thickness direction distance h1 of the door-side back panel double-sided tapes 37, 38 is set to be smaller than the protrusion length distance h2 of the positioning protrusion 33 from the surface 40a of the door-side back panel plate 40. Therefore, even if the positioning protrusion 33 of the door-side back panel plate 40 is shifted and approaches the periphery of the positioning recess 34 when the positioning protrusion 33 of the door-side back panel plate 40 is fitted into the positioning recess 34 of the door mounting part 10, the positioning protrusion 33 abuts against the periphery of the positioning recess 34, and therefore the door-side back panel double-sided tapes 37, 38 do not abut against the door mounting part 10. Therefore, by fitting the positioning protrusion 33 into the positioning recess 34 without abutting the door-side back panel double-sided tapes 37, 38 against the door mounting part 10, the task of positioning and attaching the door-side back panel plate 40 to the door mounting part 10 is simplified.

[0075] Door side back plate double-sided tapes 37, 38 are provided on the surface 40a of the door side back plate 40, and the surfaces 37a, 38a of the door side back plate double-sided tapes 37, 38 are attached to the door mounting portion 10, so that the installation process of the door side back plate 40 at the door mounting portion 10 on the door 3 can be completed simply by adhering the door side back plate double-sided tapes 37, 38 to the door mounting portion 10.

[0076] Furthermore, the protrusion length h3 of the positioning protrusion 33 of the door-side back panel double-sided tapes 37, 38 from the surface 40a of the door-side back panel 40 is set to be shorter than the depth h4 of the positioning recess 34 of the door mounting part 10. With this configuration, the positioning recess 34 is a hole with a circular cross section that is provided to penetrate the door mounting part 10, so that the top surface 36, which is the tip of the positioning protrusion 33, does not come into contact with the positioning recess 34, and the door-side back panel 40 is adhered to the door mounting part 10 with the door-side back panel double-sided tapes 37, 38, so that the door-side back panel 40 can be firmly adhered to the door mounting part 10 with the door-side back panel double-sided tapes 37, 38. Furthermore, because the tip of the positioning protrusion 33 has a curved surface with a convex tip, it can be easily moved by abutting against the periphery of the positioning recess 34.

[0077] (6) An upper blade installation process for installing the upper blade 15 of the hinge 4 on the door mounting portion 10. In the upper blade installation process, to install the upper blade 15 on the door mounting portion 10, the through hole formed in advance in the door mounting portion 10 is aligned with the blade plate screw hole 22 of the upper blade plate 23, and the screw N is screwed into the blade plate screw hole 22 and into the plate screw hole 32.

[0078] At this time, the door side back plate 40 has the door side back plate double-sided tape 37, 38 attached to the surface 40a of the plate screw hole 32, but the door side back plate double-sided tape 37, 38 is an adhesive layer, and the screw N easily tears the part of the door side back plate double-sided tape 37, 38 corresponding to the screw, allowing the screw N to be screwed into the plate screw hole 32.

[0079] As a result of the above, the door mounting plate 13 and the upper blade 15 are installed via the door mounting portion 10.

[0080] (7) Door opening and closing process for installing the door frame 2 and the door 3. In the door opening and closing process, with the door frame 2 installed in a predetermined position, the door 3 is lifted and the upper pipe portion 24 is inserted from above into the lower pipe portion 18 of the hinge 4. This allows the upper pipe portion 24 to rotate freely relative to the lower pipe portion 18, allowing the door 3 to be opened and closed relative to the door frame 2.

[0081] This completes the door structure mounting process.

[0082] According to the door structure installation process using the frame mounting plate 26 and the door mounting plate 13 of this embodiment, the frame-side backing plate 28 and the door-side backing plate 40 are provided with the frame-side backing plate double-sided tapes 29, 30 and the door-side backing plate double-sided tapes 37, 38, respectively, on their respective surfaces 28a, 40a. Therefore, installation of the backing plates can be completed simply by adhering the frame-side backing plate double-sided tapes 29, 30 and the door-side backing plate double-sided tapes 37, 38 to the respective surfaces 28a, 40a. This simplifies the door structure installation process, particularly the backing plate installation work, and allows even non-welders to install the door structure, making it easy to secure workers. Furthermore, because no welding is required during the door structure installation process, the environmental impact is reduced.

[0083] The door structure (mounting plate) of the present invention is not limited to the above embodiment.

[0084] For example, the frame side back plate 28 and the door side back plate 40, which are mounting plates, are provided with frame side back plate double-sided tapes 29, 30 and door side back plate double-sided tapes 37, 38, which are adhesive layers, and the frame side back plate double-sided tapes 29, 30 are arranged to cover the upper two plate screw holes 32 and the lower two plate screw holes 32, and the door side back plate double-sided tapes 37, 38 are arranged to cover the upper two plate screw holes 32 and the lower two plate screw holes 32, among the plate screw holes 32.

[0085] However, for example, in addition to arranging the frame-side back plate double-sided tapes 29, 30 on the frame-side back plate 28, as shown in the second embodiment in Figure 6, frame-side back plate double-sided tapes 29, 30, 31 can also be arranged to cover one plate screw hole 32 that is positioned in the vertical center of two plate screw holes 32. The frame-side back plate double-sided tape 31 is affixed to the surface 28a of the frame-side back plate 28. In this case, the frame-side back plate double-sided tapes 29, 30, 31 have the same shape, and there is a gap in the vertical direction X between the frame-side back plate double-sided tapes 29, 31, and there is a gap in the vertical direction X between the frame-side back plate double-sided tapes 31, 30.

[0086] In the above embodiment, the horizontal width of the frame side back panel double-sided tapes 29, 30 and the horizontal width of the frame side back panel plate 28 are configured to be flush with each other, the horizontal width of the door side back panel double-sided tapes 37, 38 and the thickness direction width of the door side back panel plate 40 are configured to be flush with each other, and the frame side back panel double-sided tapes 29, 30 and the door side back panel double-sided tapes 37, 38 are formed in a rectangular shape.

[0087] However, as long as the frame side back panel plate 28 is firmly attached to the frame mounting portion 6 via the frame side back panel double-sided tapes 29, 30, and the door side back panel plate 40 is firmly attached to the door mounting portion 10 via the door side back panel double-sided tapes 37, 38, the frame side back panel double-sided tape and the door side back panel double-sided tape do not have to be equal to the horizontal width of the frame side back panel plate 28 and the door side back panel plate 40, for example, and multiple circular or oval double-sided tapes can also be arranged.

[0088] In the above embodiment, the frame-side backing plate double-sided tapes 29, 30 and the door-side backing plate double-sided tapes 37, 38 are arranged spaced apart in the vertical direction. However, the frame-side backing plate double-sided tapes 29, 30 and the door-side backing plate double-sided tapes 37, 38 can also be integrated by continuously forming the ends of the frame-side backing plate double-sided tapes 29, 30 and the ends of the door-side backing plate double-sided tapes 37, 38 together so as to avoid the positioning protrusion 33, for example.

[0089] In the above embodiment, the protruding length h3 of the positioning protrusion 33 from the surfaces 29a, 30a of the frame-side back plate double-sided tapes 29, 30 was set to be shorter than the depth h4 of the positioning recess 34 of the frame mounting part 6. In this configuration, for example, when the screw N is threadedly fastened into the slat screw hole 22 to fix the lower slat 17 to the frame mounting part 6, the frame-side back plate double-sided tapes 29, 30 are compressed to some extent, but the protruding length h3 is set to be shorter than the depth h4, including the compression.

[0090] On the other hand, the protrusion length distance h3 can be set to be equal to the depth distance h4, including the compression. The positioning protrusion 33 is configured to avoid protruding into the lower slat 17 when the screw N is screwed into the slat screw hole 22 and fastened.

[0091] In the above embodiment, the hinge 4 is used as the door device, and the door structure is described as using the frame-side back plate 28 and the door-side back plate 40 at the frame mounting portion 6 and the door mounting portion 10, respectively. However, the door structure can also use a mounting plate to install a door closer. In this case, the mounting plate can be placed on the back side of the plate that is attached to the frame body, and double-sided tape is attached to the mounting surface.

[0092] In the above embodiment, the adhesive layer is a double-sided tape, and an example is given of an acrylic ester resin foam polymer, which is a resin that breaks easily when the screw N is screwed and fastened. However, the adhesive layer is not limited to the double-sided tape, and may be a material that is applied to the mounting surface and dried to have adhesive strength. [Explanation of symbols]
