Description
[Technical Field]
[0001] The present invention relates to an L-shaped metal fitting, a private booth having an L-shaped metal fitting, a self-supporting structure, and a method for constructing a private booth having an L-shaped metal fitting. [Background technology]
[0002] For example, Patent Document 1 (JP 2023-66873 A) discloses a private booth in which the rigidity of the door frame can be increased to make it less susceptible to distortion without fixing the lower part of the door frame to the floor.
[0003] The booth apparatus 1 described in Patent Document 1 has peripheral walls 2 (side panels 22, door frame panels 23, and a back panel 25) erected on the floor surface, a door frame provided on the peripheral walls 2, and a door 24 rotatably supported by the door frame, and the door frame has a pair of vertical frames 23a and an upper frame 23b that straddles the upper parts of the vertical frames 23a, and the door frame is provided with a connecting member 26 that connects the lower ends of the pair of vertical frames 23a, and the connecting member 26 has a plate-like portion 26a and fitting portions 26b that rise upward from both the left and right ends of the plate-like portion 26a and fit into the lower ends of the pair of vertical frames 23a, respectively.
[0004] In addition, Patent Document 2 (JP Patent Publication No. 2007-209480) discloses a stabilizing leg device for an upright member that facilitates the installation and adjustment of a stabilizer 30 that stably supports a panel on the floor surface, while preventing a reduction in the stable support function.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2023-66873 [Patent Document 2] Japanese Patent Application Publication No. 9-209480 Summary of the Invention [Problem to be solved by the invention]
[0007] The booth device described in Patent Document 1 has a plate-shaped portion 26a arranged on the floor surface, and has a structure in which the plate-shaped portion 26a is subjected to load and may lift up, which poses a problem in that the plate-shaped portion 26a is likely to become an obstacle when users enter and exit the booth.
[0008] Furthermore, the stabilizing leg device for the erecting member described in Patent Document 2 has a configuration in which holes are drilled in the floor surface and the partition panel is fixed to the floor surface, which causes the problem that the installation work of the private booths is large-scale. Also, there is a problem that the work after removing the private booths, such as repairing holes in the floor surface, becomes complicated.
[0009] In recent years, there has been a growing demand for larger door openings, making it difficult to increase the strength supporting the door and maintain its rigidity. There is also a growing demand for doors that can be installed without the need for bearing walls.
[0010] The object of the present invention is to provide an L-shaped metal fitting, a private booth with an L-shaped metal fitting, a self-supporting structure, and a construction method for a private booth with an L-shaped metal fitting, which can easily increase the rigidity of the door frame. Furthermore, another object of the present invention is to provide an L-shaped metal fitting, a private booth with an L-shaped metal fitting, a self-supporting structure, and a construction method for a private booth with an L-shaped metal fitting, which can easily be added to increase the rigidity of the door frame even after construction. [Means for solving the problem]
[0011] (1) The L-shaped metal fitting according to one aspect is an L-shaped metal fitting for increasing strength, and one or more holes are formed on one end of the L-shape for screws to be fastened to a stud column, and one or more holes are formed on the other end of the L-shape for screws to be fastened to a beam.
[0012] Even if the door opening area is larger than before, distortion of the door frame can be easily eliminated.In addition, it can be applied to door frames after installation, which is a great benefit for users. In this case, the extremely important advantage is that the opening area of the door can be made large, while eliminating the need to provide a bearing wall on the surface where the door is installed. Furthermore, it is possible to maintain strength while preventing obstruction of the door opening, and it is possible to maintain a good appearance and high design quality.
[0013] (2) In the L-shaped fitting according to a second aspect of the present invention, one or more locking portions that can be locked into holes in a stud column may be provided on a portion of the outer edge of one end of the L-shape.
[0014] In this case, since one or more locking portions are provided, the locking portions can be locked onto the stud column and fastened with screws, making installation easy.
[0015] (3) The L-shaped metal fitting according to the third aspect of the present invention may be the L-shaped metal fitting according to one aspect or the second aspect of the present invention, wherein a triangular portion is provided between one end side and the other end side of the L-shape.
[0016] In this case, by providing a triangular portion between one end side and the other end side of the L-shape, the strength of the L-shaped metal fitting can be improved.
[0017] (4) The L-shaped metal fitting according to the fourth aspect of the present invention may be the L-shaped metal fitting according to one aspect or the second aspect of the present invention, and may include a fixing portion formed by bending the other part of the outer edge of one end of the L-shape by 90 degrees toward the Z direction when the L-shape is in the XY direction.
[0018] In this case, strength can be improved in three dimensions rather than two, so the rigidity of the door frame can be maintained at an extremely high level.
[0019] (5) The L-shaped metal fitting according to the fifth aspect of the present invention may be the L-shaped metal fitting according to the first aspect or the second aspect of the present invention, and may have a notch formed on the other part of the outer edge on one end side of the L-shape to avoid a beam.
[0020] In this case, the strength of the door frame can be increased by easily using L-shaped metal fittings, regardless of the shape of the beam.
[0021] (6) A private booth having an L-shaped metal fitting according to another aspect is a private booth including an opening door, a door frame of the opening door, and a stud post, and includes an L-shaped metal fitting according to any one of aspects 1 to 5, which is fixed to the stud post of the private booth and either the upper horizontal member of the door frame or the horizontal beam at the top of the door frame.
[0022] Even if the door opening area is larger than before, distortion of the door frame can be easily eliminated.In addition, it can be applied to door frames after installation, which is a great benefit for users. Furthermore, by fixing it from the inside of the door frame, it is possible to prevent the opening area of the door frame from being reduced while improving the design. In this case, the door opening area can be made large, and there is no need to provide a bearing wall on the surface where the door is installed, which provides the extremely important advantage of making the private booth even more compact. Furthermore, one side of the booth can be entirely made into a door, with the other side made of glass panels. In this case, it is desirable to provide L-shaped metal fittings on the stud supports and beams on which the glass panels are attached.
[0023] (7) A still further aspect of the self-supporting structure is a self-supporting structure including a hinged door, a door frame for the hinged door, at least four stud posts, and a cross beam connecting the stud posts, wherein two of the stud posts are positioned adjacent to each other on either outside of the hinged door (or door frame), and L-shaped metal fittings according to any one of the first to fifth aspects of the invention are fixed to the two stud posts and to both ends of the cross beam (or both ends of the upper cross member of the door frame), respectively.
[0024] According to the freestanding structure of the seventh invention, stud columns are arranged adjacent to both outside sides of the opening door (or door frame), so the structure can maintain high self-supporting strength without installing a load-bearing wall on the side where the opening door is located. Freestanding structures are vulnerable to external forces in the lateral direction because their columns are not fixed to the ceiling surface. Therefore, if a hinged door is installed in a freestanding structure, external forces will be applied that will distort the columns and beams near the door when the door is opened or closed. Therefore, in order to maintain the cubic shape of the freestanding structure, a bearing wall must be installed on the side facing the door. Therefore, conventional freestanding structures cannot have large openings because a bearing wall is installed on the side where the door is located. In the freestanding structure of the seventh invention, L-shaped metal fittings are fixed to the stud posts located on both sides of the opening door (or door frame), preventing deformation of the cross beam and stud posts (or deformation of the upper cross member and stud posts), making deformation of the door surface less likely. This eliminates the need to install a bearing wall on the door surface, allowing for a large opening (doorway or window) to be installed across one entire surface of the freestanding structure. This means that even small, sufficiently large openings can be installed in freestanding private booths such as working booths, smoking booths, and changing rooms.
[0025] (8) In yet another aspect, the construction method for a private booth having an L-shaped metal fitting is a construction method for a private booth including an opening door, a door frame of the opening door, and a stud post, and includes a fixing step of fixing the L-shaped metal fitting described in any one of aspects 1 to 5 to the stud post of the private booth and either the upper horizontal member of the door frame or the horizontal beam at the top of the door frame.
[0026] Even if the door opening area is made larger than before, distortion of the door frame can be easily eliminated. In addition, it can be applied to door frames after construction, so users can It is also very beneficial for [Brief explanation of the drawings]

[0028] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are designated by the same reference numerals. Furthermore, when the reference numerals are the same, the names and functions of the components are also the same. Therefore, detailed descriptions thereof will not be repeated.
[0029] [Embodiment] FIG. 1 is a schematic perspective view showing an example of a private booth 100 according to this embodiment. 1, the private booth 100 has stud posts 210, 220, 230, and 240 installed at regular intervals. A panel 215 is installed between the stud posts 210 and 220, a panel 225 is installed between the stud posts 220 and 230, and a panel 235 is installed between the stud posts 230 and 240. It is to be noted that one or more of the panels 215, 225, and 235 may be glass panels. Furthermore, the L-shaped metal fitting 500 according to this embodiment is not limited to being applied to the periphery of the door frame of the door 300 described below, but may also be attached to the periphery of a glass panel.
[0030] Additionally, beams 250 are provided between stud columns 210, 220, between stud columns 220, 230, between stud columns 230, 240, and between stud columns 240, 210. Ceiling 400 is formed using the beams 250 and stud columns 210, -, stud columns 240.
[0031] Next, members for supporting the door, such as pivot hinges or support hinges for the door 300, are provided above and below the stud column 210, and the door 300 is provided between the stud column 210 and the stud column 240 so that it can be opened in the direction of the arrow OP. Furthermore, an upper door frame 320 and a vertical door frame 330 are provided at a position where the door 300 rotates in the opposite direction to the arrow OP and is closed.
[0032] (L-shaped bracket 500) As shown in Fig. 1, L-shaped metal fittings 500 are attached to the inside of the private booth on the left and right sides of the door upper frame 320. Details of the L-shaped metal fittings 500 will be described below.
[0033] 2 and 3 are schematic diagrams showing an example of an L-shaped metal fitting 500 according to this embodiment. 2 and 3 show symmetrical L-shaped metal fittings 500, and the same reference numerals are used in the explanation. If the fixing holes 530 described later are made blind holes, the same material can be used, which has the advantage of reducing the number of material types at the construction site.
[0034] 2 and 3, it has one end (horizontal) part 510 of an L-shape and the other end (vertical) part 520. The other end (vertical) part 520 has locking parts 521 provided at predetermined intervals. As shown in FIGS. 2 and 3, a triangular portion 525 is formed between one end (horizontal) portion 510 and the other end (vertical) portion 520 of the L-shape. The triangular portion 525 is formed so as to increase the strength of the L-shaped metal fitting 500 while not excessively interfering with the opening area of the door 300. In other words, it improves the design and maintains strength. Furthermore, one end (horizontal) portion 510 and the other end (vertical) portion 520 are provided with a plurality of fixing holes 530 for screw fastening at predetermined intervals.
[0035] Furthermore, in this embodiment, since beam 250 has an asymmetrical cross-sectional shape, notch 515 is provided. If beam 250 has a symmetrical cross-sectional shape, notch 515 does not need to be provided.
[0036] The L-shaped metal fitting 500 is made of zinc-plated steel plate and has a thickness of 2.3 mm. The thickness may be 1 mm, 3 mm, or may vary along the way, as long as it maintains strength. The L-shaped metal fitting 500 may also be made of SGCC, SECC, or any other material. The fixing holes 530 are machined with φ5 countersunk screws. However, this is not a limitation, and some holes may be blind holes.
[0037] (L-shaped bracket 500 installed) Fig. 4 is a schematic diagram showing an example of the installation state of the L-shaped metal fitting 500 on the trailing edge side of the door 300, and Fig. 5 is a schematic diagram showing an example of the installation state of the L-shaped metal fitting 500 on the leading edge side of the door 300. Also, Fig. 6 is a schematic enlarged view for explaining a detailed portion DT of the locking portion 521 of the L-shaped metal fitting 500.
[0038] 4, the L-shaped metal fitting 500 is installed between the beam 250 and the stud post 240 on the trailing edge of the door 300. In this case, one end (horizontal) portion 510 of the L-shaped metal fitting 500 is fixed to the beam 250, and the other end (vertical) portion 520 is fixed to the stud post 240.
[0039] 5, the L-shaped metal fitting 500 is provided between the beam 250 and the stud post 210 on the door-edge side of the door 300. In this case, one end (horizontal) portion 510 of the L-shaped metal fitting 500 is fixed to the beam 250, and the other end (vertical) portion 520 is fixed to the stud post 240. That is, the L-shaped metal fittings 500 are provided on both the door trailing edge and the door leading edge. As a result, even if the area of the door 300 of the private booth 100 is increased, distortion can be prevented.
[0040] 6, locking portion 521 of L-shaped metal fitting 500 is inserted into hole 245 pre-formed in stud posts 210, 240. Because locking portion 521 is formed in a claw shape, L-shaped metal fitting 500 can be fixed to stud posts 210, 240 by moving it in the direction of arrow FIX.
[0041] Next, Figures 7 and 8 are schematic explanatory diagrams for explaining an example of the installation procedure for the L-shaped metal fitting 500. Note that in Figures 7 and 8, the stud columns 210, 240 and the beam 250 are shown in a transparent state for the sake of explanation. Also, the L-shaped metal fitting 500 is shown with hatching.
[0042] As shown in Figure 7, the locking portion 521 of the L-shaped metal fitting 500 is inserted into the hole 245 of the stud column 210, 240. Next, as shown in Figure 6, the L-shaped metal fitting 500 is slid vertically (in the direction of the arrow FIX) until the claw portion of the locking portion 521 is engaged with the rectangular hole 245. This allows the L-shaped metal fitting 500 to be maintained in a temporarily fixed state during installation, even if the installer does not hold the L-shaped metal fitting 500 with his or her hand. The stud columns 210 and 240 are pre-formed with rectangular holes 245. In this embodiment, these pre-formed holes are used for vibration prevention, mounting, etc.
[0043] Next, as shown in Figure 8, the L-shaped metal fitting 500 is screwed into place using the fixing holes 530 in the temporarily fastened state. In this way, the installer can securely fasten the L-shaped metal fitting 500 in a temporarily fastened state by screwing, making the work safe and easy. Furthermore, by providing a pair of L-shaped metal fittings 500 on the leading and trailing ends of the door 300, distortion of the door frame can be suppressed even when the door 300 is open.
[0044] (Other examples) FIG. 9 is a schematic diagram showing another example of the L-shaped metal fitting 500. As shown in FIG.
[0045] As shown in FIG. 9, the L-shaped metal fitting 500 may further have a first bent portion 560 at a right angle to one end (horizontal) portion 510 and the other end (vertical) portion 520 of the L shape shown in FIGS. 2 and 3.
[0046] In this case, the L-shaped metal fitting 500 is provided between the beam 250 and the stud post 210 on the door leading side of the door 300. One end (horizontal) portion 510 is fixed to the beam 250, the other end (vertical) portion 520 is fixed to the stud post 210, and the first bent portion 560 is fixed with a screw to the beam 250 that intersects with the beam 250.
[0047] In this case, it is possible to increase the strength of the beam 250, the beams 250 intersecting with the beam 250, and the stud column 210. As a result, the rigidity of the private booth 100 can be easily increased, and distortion can be suppressed even when the area of the door 300 is increased.
[0048] (And more examples) FIG. 10 is a schematic diagram showing yet another example of an L-shaped metal fitting 500. In FIG.
[0049] As shown in FIG. 10, a second bent portion 570 may be further provided to the L-shaped metal fitting 500 shown in FIG. The second bent portion 570 may support the ceiling 400. Although not shown, the second bent portion 570 may be provided with a screw hole so that the second bent portion 570 can be fixed to the ceiling 400 with a screw.
[0050] As a result, the rigidity of the private booth 100 can be further easily increased, and even if the area of the door 300 is increased, distortion can be further suppressed.
[0051] (And more examples) FIG. 11 is a schematic diagram showing yet another example of an L-shaped metal fitting 500. In FIG.
[0052] As shown in FIG. 11, the first bent portion 560 of the L-shaped metal fitting 500 shown in FIG. 10 may be eliminated, and only the second bent portion 570 may be formed. The second bent portion 570 may support the ceiling 400. Although not shown, the second bent portion 570 may be provided with a screw hole so that the second bent portion 570 can be fixed to the ceiling 400 with a screw.
[0053] As a result, the rigidity of the private booth 100 can be further easily increased, and even if the area of the door 300 is increased, distortion can be further suppressed.
[0054] (And more examples) FIG. 12 is a schematic diagram showing yet another example of an L-shaped metal fitting 500. In FIG.
[0055] As shown in FIG. 12, the area of the second bent portion 570 of the L-shaped metal fitting 500 shown in FIG. 10 may be increased, and further a third bent portion 580 may be provided. The third bending portion 580, together with the first bending portion 560, is fixed to the beam 250 that intersects the beam 250, thereby further increasing the rigidity of the L-shaped metal fitting 500 and making it easier to further increase the rigidity of the private booth 100.
