Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the rain protection measures performed on existing automatic doors are carried out in accordance with the construction status of the parts around the automatic door, and do not coincide with the construction timing of attaching the automatic door frame to the building skeleton. Therefore, usually, the construction timing of arranging the drive unit in the arrangement space of the automatic door frame is a predetermined timing after attaching the automatic door frame to the building skeleton and after rain protection measures are taken. Such a difference in construction timing may cause overlapping labor, for example, from the viewpoints of adjusting the timing of the contractor and securing a work place at the construction site. Therefore, there is a possibility of reducing the construction efficiency.

[0005] An object of the present invention is to provide an automatic door frame, a building, an automatic door frame unit, a method for constructing an automatic door frame unit, and a method for constructing a building, which can execute rain protection measures for the arrangement space where the drive unit is arranged regardless of the parts around the building.

Embodiments for Carrying Out the Invention

[0017] Hereinafter, embodiments of an automatic door frame, a building, an automatic door frame unit, a construction method of the automatic door frame unit, and a construction method of the building according to the present invention will be illustrated and described with reference to the drawings. The same reference numerals are given to the common configurations in each figure.

[0018] FIG. 1 is a front view of an automatic door 100 attached to an opening 201a of a partition wall 201 of a building 200.

[0019] First, an outline of an example of a building 200 to which the automatic door 100 is applied will be described. The building 200 of the present embodiment is, for example, a three-story apartment building having a steel frame structure. However, the number of floors of the building 200 is not particularly limited. Also, the building 200 may be, for example, a single-family house.

[0020] The building 200 of the present embodiment may include a foundation made of reinforced concrete and a frame structure composed of frame members such as columns and beams, and an upper structure supported by the foundation. The upper structure of the present embodiment has a steel frame structure, but may have, for example, a wooden frame, and its structure is not particularly limited. Also, the frame members constituting the frame structure of the building 200 of the present embodiment are standardized (standardized) in advance, manufactured in a factory in advance, and then carried into the construction site and assembled.

[0021] More specifically, the upper structure of the building 200 of the present embodiment includes the above-described frame structure, an outer wall, a floor 202, and a roof.

[0022] The exterior wall is a wall that separates the indoor space from the outdoor space of the building 200. The exterior wall of the building 200 in this embodiment has an exterior finishing layer made up of connected panel-shaped exterior materials made of, for example, autoclaved lightweight concrete (ALC). However, the exterior material may be metal or ceramic siding, extruded cement board, wood-based panels, etc.

[0023] Furthermore, the exterior wall is equipped with an insulation layer formed by connecting foamed resin-based panel-shaped insulation materials, such as phenolic foam, along the inner surface of the exterior finishing layer. However, the insulation material may also be composed of fibers such as rock wool.

[0024] Furthermore, the exterior wall includes an interior finishing layer consisting of gypsum board and a finishing material such as wall covering applied to the surface of the gypsum board. However, the composition of the interior finishing material is not limited to that of this embodiment.

[0025] The floor 202 of the building 200 in this embodiment includes a floor slab. The floor slab is erected between the beams of the frame structure and is supported directly or indirectly by the beams. As the floor slab, for example, ALC panels can be used, but other materials such as folded plates, extruded cement boards, and wood-based panels may also be used. In addition to the floor slab, the floor 202 may include, for example, ceiling interior materials that constitute the ceiling surface 202a of the floor below, which are attached directly or indirectly to the floor slab. Furthermore, the floor 202 may also include floor interior materials such as flooring that constitute the floor surface 202b of the floor above, which are laminated on the floor slab.

[0026] The roof of building 200 in this embodiment is a flat roof. Similar to the floor slab material described above, ALC panels can be used for the roof floor slab material constituting the flat roof, but it is not limited to ALC panels. Furthermore, the roof floor slab material is waterproofed by being covered with a waterproof sheet, for example, made of polyvinyl chloride resin. Also, the roof of building 200 is not limited to a flat roof; it may be a pitched roof using roofing exterior materials such as slate.

[0027] Next, an automatic door 100 installed in an opening 201a of a partition wall 201 of a building 200 will be described. The partition wall 201 may be, for example, the exterior wall described above, or it may be a partition wall that separates indoor spaces. In this embodiment, as an example, an automatic door 100 installed in an opening 201a of an exterior wall which serves as a partition wall 201 will be described.

[0028] As shown in Figure 1, the automatic door 100 includes an automatic door frame 1 as one embodiment of the automatic door frame according to the present invention. More specifically, the automatic door 100 of this embodiment includes an automatic door frame 1, a drive unit 2, a door unit 3, and a fixing plate unit 4.

[0029] The automatic door frame 1 comprises an upper frame 11, a lower frame 12, and two vertical frames 13 and 14. Figure 1 is a front view of the automatic door 100 as seen from the outside. For the sake of explanation, the vertical frame 13 on the left side in the front view shown in Figure 1 will be referred to as the "left vertical frame 13," and the vertical frame 14 on the right side will be referred to as the "right vertical frame 14."

[0030] As shown in Figure 1, the automatic door frame 1 is a rectangular frame composed of an upper frame 11, a lower frame 12, a left vertical frame 13, and a right vertical frame 14. More specifically, the upper frame 11 extends horizontally along the upper opening end of the opening 201a. The lower frame 12 extends horizontally along the lower opening end of the opening 201a. The left vertical frame 13 extends vertically along one horizontal opening end of the opening 201a. The left vertical frame 13 connects one end of the upper frame 11 to one end of the lower frame 12. The right vertical frame 14 extends vertically along the other horizontal opening end of the opening 201a. The right vertical frame 14 connects the other end of the upper frame 11 to the other end of the lower frame 12.

[0031] Figure 2 is a vertical cross-sectional view of the automatic door 100. As shown in Figure 2, the upper frame 11 of this embodiment demarcates an arrangement space 15 inside in which a drive unit 2 for moving the door section 3 can be arranged. Here, the interior of each frame, the upper frame 11, the lower frame 12, the left vertical frame 13, and the right vertical frame 14, refers to the internal space located between the front and back of each frame. The front of each frame is one side of the frame thickness direction B of the automatic door frame 1 (the same direction as the thickness direction of the partition wall 201) that is perpendicular to the in-plane direction A of the frame surface of the automatic door frame 1 (the same direction as the in-plane direction of the partition wall 201). The back of each frame is the other side of the frame thickness direction B that is perpendicular to the in-plane direction A of the frame surface of the automatic door frame 1.

[0032] More specifically, the upper frame 11 of this embodiment includes a front panel portion 11a located on one side in the frame thickness direction B and constituting the front of the upper frame 11, a back panel portion 11b located on the other side in the frame thickness direction B and constituting the back of the upper frame 11, an upper panel portion 11c positioned between the upper end of the front panel portion 11a and the upper end of the back panel portion 11b and constituting the upper surface of the upper frame 11, and a cover panel portion 11d positioned below the upper panel portion 11c and between the front panel portion 11a and the back panel portion 11b as a cover portion 51. As shown in Figure 2, in the upper frame 11 of this embodiment, the front panel portion 11a, the back panel portion 11b and the cover panel portion 11d partition an arrangement space 15 within themselves. In other words, as shown in Figure 2, the front plate portion 11a and the rear plate portion 11b extend vertically from a position above the upper end of the drive unit 2 located in the arrangement space 15 to a position below the lower end of the drive unit 2 located in the arrangement space 15. In addition, a fixing plate portion 4 is fixed to the lower end of the front plate portion 11a in this embodiment. The top plate portion 11c has an insertion hole 11c1 through which a fastening member 208 such as a bolt can be inserted. On the lower surface of the top plate portion 11c, for example, a nut can be pre-fixed so that a bolt inserted from top to bottom into the insertion hole 11c1 can be screwed into it.

[0033] In the upper frame 11 of this embodiment, the front panel 11a, the top panel 11c, and the cover panel 11d are joined by bending or welding, or integrally molded by extrusion molding, to form a single first frame member 61. In addition, in the upper frame 11 of this embodiment, the second frame member 62, which constitutes the back panel 11b, is detachably attached to the first frame member 61. By doing so, the second frame member 62 can be removed from the first frame member 61, making it easy to perform maintenance on the drive unit 2 located in the placement space 15. However, the second frame member 62 may be movably attached to the first frame member 61, for example, in a rotatable configuration. When the second frame member 62 is attached to the first frame member 61, a small gap between the first frame member 61 and the second frame member 62 may be filled with, for example, a sealing member made of an elastic material.

[0034] As shown in Figure 2, the cover plate portion 11d comprises a flat cover plate body portion 11d1 whose in-plane direction is substantially horizontal, and a flat rising plate portion 11d2 that rises from the outer edge of the cover plate body portion 11d1 on the back plate portion 11b side along the back plate portion 11b. As will be described in detail later, this configuration prevents water droplets that enter through the insertion hole 11c1 of the top plate portion 11c and are received on the top surface of the cover plate body portion 11d1 from entering the placement space 15 by traveling along the outer edge of the cover plate body portion 11d1 in the frame thickness direction B.

[0035] As described above, the upper frame 11 of this embodiment is composed of a first frame member 61 and a second frame member 62, but is not limited to this configuration. The front panel 11a, back panel 11b, top panel 11c, and cover panel 11d of the upper frame 11 may all be composed of a single frame member, or they may each be composed of separate frame members. Furthermore, any two or three of the front panel 11a, back panel 11b, top panel 11c, and cover panel 11d of the upper frame 11 may constitute a single frame member (see Figure 3). The upper frame may also be transomless.

[0036] As will be described in detail later, the upper frame 11 of this embodiment includes a watertight structure 50 that is positioned to cover the area above the placement space 15 (see Figure 2).

[0037] As shown in Figure 2, the upper frame 11 of this embodiment is fixed to the beam 205, which is part of the building 200's structure, via metal fittings 206 and 207. Specifically, the upper plate portion 11c of the upper frame 11 of this embodiment is fixed to the beam 205 using fastening members 208 such as bolts, via two metal fittings 206 and 207, which have an L-shaped cross-sectional outer shape perpendicular to the longitudinal direction. In this embodiment, the upper frame 11 is indirectly fixed to the building 200's structure via metal fittings 206 and 207, but this configuration is not limited to this. The upper frame 11 may also be directly fixed to the building 200's structure by fastening members 208 such as bolts and screws. Furthermore, the upper frame 11 may be fixed to the building 200's structure other than the beam 205.

[0038] Although not shown in the illustration, the lower frame 12, left vertical frame 13, and right vertical frame 14 of this embodiment may also be directly or indirectly fixed to the building structure 200, such as studs and beams. In this way, the automatic door frame 1 is installed inside the opening 201a of the partition wall 201 by fixing each of the upper frame 11, lower frame 12, left vertical frame 13, and right vertical frame 14 directly or indirectly to the building structure 200.

[0039] The automatic door frame 1 can be made of, for example, stainless steel, but its constituent materials are not particularly limited.

[0040] As shown in Figure 2, the drive unit 2 is located in the space 15 partitioned inside the upper frame 11 of the automatic door frame 1. The drive unit 2 can move the door section 3.

[0041] Specifically, the drive unit 2 of this embodiment comprises a drive body 21, a door support 22, and a rail 23.

[0042] The drive unit 21 supports the door support portion 22 so that it can move along the longitudinal direction of the upper frame 11. The drive unit 21 also includes a drive source such as an electric motor. The drive unit 21 can move the door support portion 22 along the longitudinal direction of the upper frame 11 by driving the drive source.

[0043] The door support portion 22 supports the upper end of the door portion 3. The door support portion 22 moves along the rail portion 23 in the longitudinal direction of the upper frame 11. By moving the door support portion 22 along the longitudinal direction of the upper frame 11, the door portion 3 can be opened and closed.

[0044] The rail section 23 extends along the longitudinal direction of the upper frame 11. The rail section 23 movably supports the door support section 22. The door support section 22 moves along the longitudinal direction of the upper frame 11, guided by the rail section 23. More specifically, the rail section 23 in this embodiment includes a guide rail 23a that supports the door support section 22 and guides the longitudinal movement of the upper frame 11, and a frame fixing section 23b that extends from the guide rail 23a and is fixed to the front plate section 11a of the upper frame 11. The rail section 23 may be formed integrally with the upper frame 11.

[0045] The door section 3 is a component of the automatic door 100. The door section 3 is attached to the upper frame 11 and the lower frame 12 so as to be movable horizontally within the automatic door frame 1. The door section 3 is supported vertically from above by the door support section 22 of the drive unit 2. The door section 3 comprises, for example, a glass plate 3a and a stainless steel frame 3b fixed to the outer edge of the plate 3a. However, the door section 3 only needs to be supported so as to be movable within the automatic door frame 1 by the drive unit 2, and its configuration is not particularly limited.

[0046] The fixed plate portion 4 is a side-mounted fixed plate portion fixed within the automatic door frame 1. Specifically, the fixed plate portion 4 in this embodiment is fixed to the upper frame 11, the lower frame 12, and the left vertical frame 13. Therefore, the fixed plate portion 4 itself does not move horizontally within the automatic door frame 1. The configuration of the fixed plate portion 4 is not particularly limited. The fixed plate portion 4 in this embodiment may be made of, for example, a glass plate. The plate material constituting the fixed plate portion 4 in this embodiment is fixed to the upper frame 11, the lower frame 12, and the left vertical frame 13.

[0047] In this embodiment, the automatic door 100 includes, within the automatic door frame 1, one door section 3 that is movable relative to the automatic door frame 1, and one fixing plate section 4 that is fixed to the automatic door frame 1, but the configuration is not limited to this. The automatic door 100 may be a double-hinged type with two door sections. In such a case, the automatic door 100 may have two fixing plate sections on both outer sides of the two door sections. Alternatively, the automatic door 100 may have a configuration without fixing plate sections. An example of such an automatic door 100 is a single-hinged type having an automatic door frame with at least an upper frame and a lower frame, and a door section that is slidably attached to the upper frame and the lower frame.

[0048] Next, with reference to Figure 2, the details of the water-stopping structure 50 of the automatic door frame 1 will be described.

[0049] The automatic door frame 1 is equipped with a watertight structure 50 located above the installation space 15 where the drive unit 2 is positioned. The watertight structure 50 is a structure that prevents liquids such as rainwater from entering the installation space 15 from above.

[0050] As shown in Figure 2, the placement space 15 in this embodiment is partitioned inside the upper frame 11. The upper frame 11 in this embodiment includes a cover plate portion 11d as a cover portion 51 that covers the upper part of the placement space 15. The cover plate portion 11d covers the upper part of the placement space 15 over the entire length of the upper frame 11. Furthermore, the cover plate portion 11d in this embodiment covers the upper part of the placement space 15 over the entire frame thickness direction B between the front plate portion 11a and the back plate portion 11b. In addition, the cover plate portion 11d does not have through holes that penetrate in the vertical direction. Therefore, even if rainwater seeps in to the underside of the upper plate portion 11c through the insertion holes 11c1, the cover plate portion 11d is interposed between the upper plate portion 11c and the drive unit 2 placed in the placement space 15, preventing the rainwater from entering the placement space 15. In other words, the water-stopping structure 50 of this embodiment is realized by including a cover plate portion 11d as a cover portion 51 that does not have through holes that penetrate in the vertical direction.

[0051] As described above, the cover plate portion 11d of this embodiment comprises a flat cover plate body portion 11d1 whose in-plane direction is substantially horizontal, and a flat rising plate portion 11d2 that rises from the outer edge of the cover plate body portion 11d1 on the back plate portion 11b side along the back plate portion 11b. With this configuration, it is possible to prevent water droplets that enter through the insertion hole 11c1 of the top plate portion 11c and are received on the top surface of the cover plate body portion 11d1 from entering the placement space 15 by traveling along the outer edge of the cover plate body portion 11d1 in the frame thickness direction B. In other words, water droplets received on the top surface of the cover plate body portion 11d1 are blocked by the rising plate portion 11d2 on the back plate portion 11b side in the frame thickness direction B. Furthermore, water droplets received on the upper surface of the cover plate body portion 11d1 are blocked by the upper end of the front plate portion 11a, which rises up in the frame thickness direction B and is connected to the cover plate body portion 11d1. In this embodiment, the upper end of the rising plate portion 11d2 is connected to the top plate portion 11c. Thus, it is preferable that both ends of the cover portion 51 in the frame thickness direction B, which does not have through holes that penetrate in the vertical direction, are connected to a rising portion (in this embodiment, the rising plate portion 11d2 and the upper end of the front plate portion 11a) that rises upward to prevent water droplets from entering the lower placement space 15. Moreover, it is even more preferable that both ends of the cover portion 51 in the horizontal direction perpendicular to the frame thickness direction B, which does not have through holes that penetrate in the vertical direction, are also connected to a rising portion that rises upward to prevent water droplets from entering the lower placement space 15.

[0052] In this embodiment, the water-stopping structure 50 includes a cover plate portion 11d as a cover portion 51, but the configuration of the cover portion 51 of the water-stopping structure 50 is not limited to the shape of the cover plate portion 11d in this embodiment.

[0053] The automatic door frame 1 is equipped with a waterproofing structure 50, which allows for protection against rain exposure to the placement space 15 where the drive unit 2 is located, regardless of the surrounding parts of the building 200. In other words, the automatic door frame 1 is equipped with a waterproofing structure 50, which allows for the automatic door frame unit 500, with the drive unit 2 already placed in the placement space 15 of the automatic door frame 1, to be attached to the building structure 200. In other words, the drive unit 2 may be incorporated into the placement space 15 at the assembly plant for the automatic door frame 1. This eliminates problems that arise when the timing of attaching the automatic door frame 1 to the building structure 200 at the construction site differs from the timing of placing the drive unit 2 in the placement space 15 at the construction site, thereby suppressing a decrease in construction efficiency. Furthermore, since the wiring work within the automatic door frame unit 500 can be done in advance, the amount of wiring work at the construction site can be reduced.

[0054] Furthermore, the timing at which the drive unit 2 can control the opening and closing of the door section 3 can be made earlier than in the conventional system. In other words, the door section 3 can be locked at an earlier stage than before. This makes it possible to manage the entry and exit of people at the construction site at an earlier stage than before.

[0055] Furthermore, as described above, when the second frame member 62 is attached to the first frame member 61, it is preferable to seal the minute gap between the first frame member 61 and the second frame member 62 by, for example, inserting a sealing member made of an elastic material. By doing so, it is possible to prevent liquids such as rainwater from entering the placement space 15 through the minute gap between the first frame member 61 and the second frame member 62.

[0056] However, the watertight structure 50 of the automatic door frame 1 may be formed at the same time as or after the installation process in which the automatic door frame unit 500, in which the drive unit 2 is placed in the placement space 15 of the automatic door frame 1, is attached to the building structure 200, and independently of the surrounding parts of the building 200. In other words, the watertight structure 50 of the automatic door frame 1 does not need to be provided in the automatic door frame 1 before the automatic door frame 1 is attached to the building structure 200.

[0057] The following describes two examples: one in which the watertight structure 50 is formed after the installation process in which the automatic door frame 1 is attached to the building structure 200 (see Figure 3), and another in which the watertight structure 50 is formed simultaneously with the installation process in which the automatic door frame 1 is attached to the building structure 200 (see Figure 4).

[0058] First, referring to Figure 3, we will describe an example in which the watertight structure 50 is formed after the installation process in which the automatic door frame 1 is attached to the building structure 200. The automatic door 300 shown in Figure 3 differs from the automatic door 100 shown in Figure 2 in the configuration of the upper frame 11 and the configuration of the watertight structure 50. Here, we will mainly explain these differences, and omit the explanation of the configurations that are common to the automatic door 100 shown in Figure 2.

[0059] The upper frame 11 of the automatic door frame 1 shown in Figure 3 comprises a front panel 11a, a back panel 11b, a top panel 11c, and a cover panel 11d, similar to the automatic door 100 described above (see Figure 2). However, in the upper frame 11 shown in Figure 3, the front panel 11a and the top panel 11c form a single first frame material 63 by bending, welding, or other joining processes, or by integral molding such as extrusion molding, while the back panel 11b and the cover panel 11d form a single second frame material 64 by bending, welding, or other joining processes, or by integral molding such as extrusion molding. In the upper frame 11 shown in Figure 3, the second frame material 64, which constitutes the back panel 11b and the cover panel 11d, is detachably attached to the first frame material 63, which constitutes the front panel 11a and the top panel 11c. By configuring the upper frame 11 in this way, for example, the top panel portion 11c can be attached to the building structure 200 with the second frame member 64 removed from the first frame member 63. In other words, with the second frame member 64 of the upper frame 11 removed, the top panel portion 11c of the upper frame 11 of the automatic door frame 1 can be attached to the building structure 200 using the insertion hole 11c1. In the state where the second frame member 64 is attached to the first frame member 63, a small gap between the first frame member 63 and the second frame member 64 may be filled by inserting, for example, a sealing member made of an elastic material.

[0060] In other words, during the installation process of attaching the automatic door frame 1 to the building structure 200, the cover plate portion 11d, which serves as the cover portion 51 of the watertight structure 50, may not be provided on the automatic door frame 1. The second frame material 64, which constitutes the back plate portion 11b and the cover plate portion 11d of the upper frame 11, may be attached to the first frame material 63 after the automatic door frame 1 has been attached to the building structure 200, that is, after the first frame material 63, which constitutes the front plate portion 11a and the top plate portion 11c of the upper frame 11, has been attached to the building structure 200. In this way, the watertight structure 50, including the cover plate portion 11d as the cover portion 51, is formed after the installation process in which the automatic door frame 1 is attached to the building structure 200.

[0061] Thus, the waterproofing structure 50 of the automatic door frame 1 may be formed after the installation process in which the automatic door frame 1 is attached to the building structure 200, independently of measures to prevent rain from entering the surrounding areas of the building 200. Conversely, since the waterproofing structure 50 of the automatic door frame 1 can be formed after the installation process in which the automatic door frame 1 is attached to the building structure 200, independently of measures to prevent rain from entering the surrounding areas of the building 200, the automatic door frame unit 500 with the drive unit 2 placed in the placement space 15 of the automatic door frame 1 can be attached to the building structure 200. In such a case, for example, the waterproofing structure 50 can be formed immediately after the automatic door frame unit 500 including the drive unit 2 is attached to the building structure 200.

[0062] Furthermore, the configuration of the water-stopping structure 50, which can be formed after the installation process in which the automatic door frame 1 is attached to the building structure 200, and independently of measures to prevent rain from entering the surrounding parts of the building 200, is not limited to the configuration shown in Figure 3. The automatic door frame 1 only needs to have an attachment part 71 (first frame member 63 in the example of Figure 3) to which the water-stopping member 70 (second frame member 64 in the example of Figure 3) can be attached, with the water-stopping member 70 (second frame member 64 in the example of Figure 3) positioned to cover the upper part of the drive unit 2, that realizes the water-stopping structure 50.

[0063] In the example shown in Figure 3, the cover plate portion 11d comprises a flat cover plate body portion 11d1 whose in-plane direction is substantially horizontal, and a flat rising plate portion 11d3 that rises from the outer edge of the cover plate body portion 11d1 on the front plate portion 11a side along the front plate portion 11a. This configuration prevents water droplets that enter through the insertion hole 11c1 of the top plate portion 11c and are received on the top surface of the cover plate body portion 11d1 from entering the placement space 15 by traveling along the outer edge of the cover plate body portion 11d1 in the frame thickness direction B. In other words, water droplets received on the top surface of the cover plate body portion 11d1 are blocked by the rising plate portion 11d3 on the front plate portion 11a side in the frame thickness direction B. Furthermore, water droplets received on the upper surface of the cover plate body 11d1 are blocked by the upper end of the back plate portion 11b, which rises up in the frame thickness direction B and is connected to the cover plate body 11d1. Thus, it is preferable that both ends of the cover portion 51 in the frame thickness direction B, where no through holes are formed in the vertical direction, have rising portions (in this embodiment, the rising plate portion 11d3 and the upper end of the back plate portion 11b) that rise upward to prevent water droplets from entering the lower placement space 15. Moreover, it is even more preferable that both ends of the cover portion 51 in the horizontal direction perpendicular to the frame thickness direction B, where no through holes are formed in the vertical direction, also have rising portions that rise upward to prevent water droplets from entering the lower placement space 15.

[0064] Furthermore, as described above, when the second frame member 64 is attached to the first frame member 63, it is preferable to seal the minute gap between the first frame member 63 and the second frame member 64 by, for example, inserting a sealing member made of an elastic material. By doing so, it is possible to prevent liquids such as rainwater from entering the placement space 15 through the minute gap between the first frame member 63 and the second frame member 64.

[0065] Next, referring to Figure 4, we will describe an example in which the automatic door frame 1 is attached to the building structure 200 and the waterproofing structure 50 is formed at the same time. The automatic door 400 shown in Figure 4 differs from the automatic door 100 shown in Figure 2 in the configuration of the upper frame 11 and the configuration of the waterproofing structure 50. Here, we will mainly explain these differences, and omit the explanation of the configuration that is common to the automatic door 100 shown in Figure 2.

[0066] The upper frame 11 of the automatic door frame 1 shown in Figure 4 comprises a front panel 11a, a back panel 11b, and a top panel 11c. In other words, unlike the automatic door 100 shown in Figure 2, the upper frame 11 shown in Figure 4 does not have a cover panel 11d as a cover 51. The front panel 11a, back panel 11b, and top panel 11c are the same as those of the automatic door 100 shown in Figure 2. In the example shown in Figure 4, the front panel 11a, back panel 11b, and top panel 11c of the upper frame 11 demarcate the placement space 15. Note that the upper frame 11 shown in Figure 4 is composed of a first frame member 65 that constitutes the front panel 11a and the top panel 11c, and a second frame member 66 that constitutes the back panel 11b and is removable from the first frame member 65, but the configuration is not limited to this. The front panel 11a, back panel 11b, and top panel 11c of the upper frame 11 may all be made of a single frame material, or they may each be made of separate frame materials. In the example shown in Figure 4, when the second frame material 66 is attached to the first frame material 65, a sealing member made of an elastic material may be inserted into the minute gap between the first frame material 65 and the second frame material 66. By doing so, it is possible to prevent liquids such as rainwater from entering the placement space 15 through the minute gap between the first frame material 65 and the second frame material 66.

[0067] The automatic door frame 1 shown in Figure 4 is attached to the building structure 200 using fastening members 208 such as bolts, utilizing the insertion holes 11c1 in the upper plate portion 11c of the upper frame 11. As shown in Figure 4, a sealing member 450, made of, for example, an elastic material, is sandwiched between the insertion holes 11c1 in the upper plate portion 11c of the upper frame 11 and the fastening member 208. The sealing member 450 shown in Figure 4 is, for example, an annular rubber member, and is configured so that the shaft portion of the bolt, which is the fastening member 208, can be inserted through it. The sealing member 450 shown in Figure 4 is sandwiched between the edge of the insertion hole 11c1 on the upper surface of the upper plate portion 11c and the head of the bolt, which is the fastening member 208, with the shaft portion of the bolt, which is the fastening member 208, inserted through it. However, the configuration of the sealing member 450 is not limited to the configuration shown in Figure 4. The sealing member 450 may be configured, for example, to close the gap between the fastening member 208 and the inner circumferential surface that partitions the insertion hole 11c1.

[0068] As shown in Figure 4, the upper frame 11 includes an upper plate portion 11c as a cover portion 51 that covers the upper part of the placement space 15. A through hole 11c1 is formed in this upper plate portion 11c as a through hole 51a that penetrates vertically. Therefore, in the automatic door frame 1 shown in Figure 4, a water-stopping structure 50 is realized by a configuration that includes the upper plate portion 11c as a cover portion 51, and a fastening member 208 and a sealing member 450 as a closing member 52 that closes the through hole 11c1 formed in this upper plate portion 11c.

[0069] In other words, in the example shown in Figure 4, the watertight structure 50 is formed simultaneously with the installation process in which the automatic door frame 1 is attached to the building structure 200.

[0070] Furthermore, the configuration of the watertight structure 50, which can be formed simultaneously with the installation process in which the automatic door frame 1 is attached to the building structure 200, and independently of measures to prevent rain from entering the surrounding areas of the building 200, is not limited to the configuration shown in Figure 4.

[0071] Furthermore, the water-stopping structure 50 is not limited to the configurations shown in Figures 2 to 4, but may also be configured as shown in Figures 5 and 6, for example.

[0072] The automatic door 600 shown in Figure 5 differs from the automatic door 100 shown in Figure 2 in the configuration of the upper frame 11 and the configuration of the water-stopping structure 50. Here, we will mainly explain these differences, and omit the explanation of the configurations that are common to the automatic door 100 shown in Figure 2.

[0073] The upper frame 11 of the automatic door frame 1 shown in Figure 5 comprises a front panel 11a, a back panel 11b, a top panel 11c, and a cover panel 11d. However, unlike the automatic door 100 shown in Figure 2, the cover panel 11d of the upper frame 11 shown in Figure 5 comprises a horizontal panel 11d4 and a vertical panel 11d5. The horizontal panel 11d4 is positioned opposite the top panel 11c, approximately parallel to it. The vertical panel 11d5 rises vertically upward from one end of the horizontal panel 11d4 in the frame thickness direction B. The upper end of the vertical panel 11d5 is connected to the top panel 11c. The other end of the horizontal panel 11d4 in the frame thickness direction B is connected to the back panel 11b.

[0074] In the example shown in Figure 5, the placement space 15 is partitioned by the front panel 11a, back panel 11b, top panel 11c, and cover panel 11d of the upper frame 11. The upper frame 11 shown in Figure 5 is composed of a first frame member 67 and a second frame member 68 that is removable from the first frame member 67. The first frame member 67 constitutes the front panel 11a, the upper end 16a of the back panel 11b, the top panel 11c, and the cover panel 11d. The second frame member 68 constitutes the lower end 16b of the back panel 11b. In other words, the back panel 11b shown in Figure 5 is composed of the first frame member 67 and the second frame member 68. In the example shown in Figure 5, when the second frame member 68 is attached to the first frame member 67, a small gap between the first frame member 67 and the second frame member 68 may be filled by inserting, for example, a sealing member made of an elastic material. In this way, it is possible to prevent liquids such as rainwater from seeping into the placement space 15 through the minute gap between the first frame material 67 and the second frame material 68.

[0075] In the example shown in Figure 5, a through hole 11b1 is formed in the upper end portion 16a of the back plate portion 11b, through which a fastening member 208 such as a bolt can be inserted. However, the top plate portion 11c shown in Figure 5 does not have a through hole through which a fastening member 208 such as a bolt can be inserted. The upper frame 11 shown in Figure 5 is fixed to the beam 205, which is part of the building structure 200, via metal fittings 209 and 210. Specifically, the upper end portion 16a of the back plate portion 11b of the upper frame 11 shown in Figure 5 is fixed to the beam 205 using a fastening member 208 such as a bolt, via metal fitting 209, which has an L-shaped cross-sectional outer shape perpendicular to the longitudinal direction, and 210, which has a crank-shaped cross-sectional outer shape perpendicular to the longitudinal direction. The upper frame 11 shown in Figure 5 is indirectly fixed to the building structure 200 via metal fittings 209 and 210, but the configuration is not limited to this. The upper frame 11 shown in Figure 5 may be directly fixed to the building structure 200 by fastening members 208 such as bolts and screws. Alternatively, the upper frame 11 shown in Figure 5 may be fixed to the building structure 200 other than the beams 205.

[0076] As shown in Figure 5, the placement space 15 is partitioned inside the upper frame 11. The upper frame 11 shown in Figure 5 includes an upper panel portion 11c and a cover plate portion 11d, which serve as a cover portion 51 that covers the upper part of the placement space 15. The upper panel portion 11c and the cover plate portion 11d cover the upper part of the placement space 15 over the entire length of the upper frame 11. Furthermore, the upper panel portion 11c and the cover plate portion 11d shown in Figure 5 cover the upper part of the placement space 15 over the entire frame thickness direction B between the front panel portion 11a and the back panel portion 11b. In addition, the upper panel portion 11c and the cover plate portion 11d do not have through holes that penetrate in the vertical direction. Therefore, even if rainwater penetrates the inside of the back plate portion 11b through the insertion hole 11b1, the cover plate portion 11d is interposed between the insertion hole 11b1 and the drive unit 2 positioned in the positioning space 15, thereby preventing rainwater from entering the positioning space 15. In other words, in the example shown in Figure 5, the water-stopping structure 50 is realized by including the top plate portion 11c and the cover plate portion 11d as a cover portion 51 in which no through-holes penetrating in the vertical direction are formed.

[0077] However, in the upper plate portion 11c shown in Figure 5, a through hole that penetrates vertically may be formed in the portion facing the horizontal plate portion 11d4 of the cover plate portion 11d. This is because any liquid that seeps in through such a through hole can be received by the cover plate portion 11d and will not reach the placement space 15. In other words, in the example shown in Figure 5, it is sufficient that a through hole that penetrates vertically is not formed in the portion of the upper plate portion 11c that is on the front plate portion 11a side of the cover plate portion 11d in the frame thickness direction B.

[0078] Furthermore, the cover plate portion 11d shown in Figure 5 comprises a horizontal plate portion 11d4 extending in the horizontal direction and a vertical plate portion 11d5 extending in the vertical direction, but its shape is not particularly limited as long as it is interposed between the insertion hole 11b1 and the placement space 15.

[0079] The automatic door 700 shown in Figure 6 differs from the automatic door 100 shown in Figure 2 in the configuration of the upper frame 11 and the configuration of the water-stopping structure 50. Here, we will mainly explain these differences, and omit the explanation of the configurations that are common to the automatic door 100 shown in Figure 2.

[0080] The upper frame 11 of the automatic door frame 1 shown in Figure 6 comprises a front panel 11a, a back panel 11b, and a top panel 11c. In other words, unlike the automatic door 100 shown in Figure 2, the upper frame 11 shown in Figure 6 does not have a cover panel 11d as a cover 51. In the example shown in Figure 6, the front panel 11a, back panel 11b, and top panel 11c of the upper frame 11 demarcate the placement space 15. The upper frame 11 shown in Figure 6 is composed of a first frame member 81 that constitutes the upper end 16a of the front panel 11a and the back panel 11b, and the top panel 11c, and a second frame member 82 that constitutes the lower end 16b of the back panel 11b and is removable from the first frame member 81. That is, the back panel 11b shown in Figure 6 is composed of the first frame member 81 and the second frame member 82. However, the front panel portion 11a, the back panel portion 11b, and the top panel portion 11c of the upper frame 11 may all be made of a single frame material. In the example shown in Figure 6, when the second frame material 82 is attached to the first frame material 81, a sealing member made of an elastic material may be inserted into the minute gap between the first frame material 81 and the second frame material 82. By doing so, it is possible to prevent liquids such as rainwater from entering the placement space 15 through the minute gap between the first frame material 81 and the second frame material 82.

[0081] The automatic door frame 1 shown in Figure 6 is attached to the building structure 200 using fastening members 208 such as bolts, utilizing the insertion hole 11b1 formed in the upper end portion 16a of the back plate portion 11b of the upper frame 11. In the example shown in Figure 6, the insertion hole 11b1 is located vertically above the drive unit 2 which is located in the placement space 15. The upper frame 11 shown in Figure 6 is fixed to the beam 205, which is part of the building structure 200, via metal fittings 209 and 210 similar to those in Figure 5. As shown in Figure 6, a sealing member 750, made of, for example, an elastic material, is sandwiched between the insertion hole 11b1 of the back plate portion 11b of the upper frame 11 and the fastening member 208. The sealing member 750 shown in Figure 6 is, for example, an annular rubber member, and is configured so that the shaft portion of the bolt, which is the fastening member 208, can be inserted through it. The sealing member 750 shown in Figure 6 is sandwiched between the edge of the insertion hole 11b1 on the outer surface of the back plate portion 11b (the right side in Figure 6) and the head of the bolt, which serves as the fastening member 208, while the shaft of the bolt, which serves as the fastening member 208, is inserted through it. However, the configuration of the sealing member 750 is not limited to the configuration shown in Figure 6. The sealing member 750 may, for example, be configured to close the gap between the fastening member 208 and the inner circumferential surface that partitions the insertion hole 11b1.

[0082] In the example shown in Figure 6, the upper frame 11 includes an upper plate portion 11c that serves as a cover portion 51 covering the area above the placement space 15. This upper plate portion 11c does not have any through-holes that penetrate vertically. Therefore, in the automatic door frame 1 shown in Figure 6, the watertight structure 50 is realized by the configuration including the upper plate portion 11c as the cover portion 51.

[0083] Furthermore, in the example shown in Figure 6, as described above, the through hole 11b1 formed in the back plate portion 11b is closed by the fastening member 208 and the sealing member 750. Therefore, it is possible to prevent liquids such as rainwater from entering the placement space 15 through the through hole 11b1.

[0084] As described above, according to the automatic door frame, building, automatic door frame unit, and method for constructing the automatic door frame unit according to the present invention, the automatic door frame unit including the drive unit can be installed simultaneously with the structural work, or after the structural work but before the completion of the waterproofing work, thereby streamlining the building construction method. In conventional building construction methods, the process usually proceeds in the following order: foundation work, structural work, waterproofing work, interior structural work, carpentry work, finishing work, and operational check before handover. Therefore, in conventional building construction methods, even if the automatic door frame is installed during the structural work, the installation of the drive unit occurs at the finishing work stage after the waterproofing work. As a result, including the operational check before handover, there were at least three instances where work related to the automatic door was performed. In contrast, in the building construction method using the automatic door frame, building, automatic door frame unit, and method for constructing the automatic door frame unit according to the present invention, the installation of the automatic door frame and the installation of the drive unit can be performed at the structural work stage. Therefore, the timing of automatic door-related work can be consolidated into two phases: during the structural work phase and during the operational check phase before handover. This reduces the number of times automatic door-related contractors are involved compared to conventional methods, thus streamlining the building construction process.

[0085] The automatic door frame, building, automatic door frame unit, method for constructing the automatic door frame unit, and method for constructing the building according to the present invention are not limited to the specific configurations and processes described in the embodiments above, and various modifications, changes, and combinations are possible as long as they do not deviate from the scope of the claims. For example, Figure 4 shows an example in which the insertion hole 11c1 as a through hole 51a is closed at the same time as the installation process in which the automatic door frame 1 is attached to the building frame 200, but another through hole 51a may be formed in the upper plate portion 11c as the cover portion 51 that is not used in the installation process in which the automatic door frame 1 is attached to the building frame 200. This other through hole 51a may be closed by a closing member 52 after the installation process in which the automatic door frame 1 is attached to the building frame 200. Furthermore, the closing member 52 included in the water-stopping structure 50 is not limited to a configuration that closes the through hole 51a of the cover portion 51, but may also close the gaps between the multiple frame members of the automatic door frame 1. Furthermore, the sealing member 450 shown in Figure 4 may be applied to the automatic door 100 shown in Figure 1. [Industrial applicability]
