[0002] Entrance structures equipped with automatic sliding doors that detect pedestrians at the entrance to a building and automatically open and close the door panel have been known for some time. For example, Patent Document 1 discloses the following automatic door device to be installed in an entrance structure. In the automatic door device of Patent Document 1, the door panel is supported by a rail in a drive unit installed above the entrance so that it can slide along the upper edge, and the door panel is suspended from the rail, and the door panel is slid along the upper edge by the drive unit to open and close the entrance. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-3523 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the automatic door system described above requires rails to hang the door panel above the entrance and a case to house the unit for opening and closing the door. However, placing this case above the entrance reduces the design aesthetic.

[0005] Therefore, an object of the present invention is to provide an entrance structure that gives the impression of continuous connection between the indoors and outdoors, even while an automatic door device is installed at the entrance / exit. [Means for solving the problem]

[0006] The first entrance structure that solves the above problem comprises a ceiling surface formed indoors, an outdoor ceiling surface formed outdoors adjacent to the ceiling surface, an indoor entrance space formed below the ceiling surface, and an automatic sliding door device formed at the boundary between the semi-outdoor space formed below the outdoor ceiling surface, the automatic door device having an entrance through which people can enter and exit, an opening adjacent to the entrance, a door panel that can move from a position covering the entrance to a position overlapping the opening, and an opening / closing operation unit that suspends the door panel and controls the movement of the door panel, the lower end of the opening / closing operation unit being formed at a position higher than the ceiling surface and the outdoor ceiling surface.

[0007] The second entrance structure is the first entrance structure, further comprising a floor surface formed in the indoor entrance space and an outdoor floor surface formed outdoors adjacent to the floor surface, and the opening has a rectangular frame body having an upper frame material, a lower frame material, and a pair of side frame materials, and a transparent plate fitted into the frame body, and the lower end of the upper frame material is formed at a height position equal to or higher than the ceiling surface and the outdoor ceiling surface, and the upper end of the lower frame material is formed at a height position equal to or lower than the floor surface and the outdoor floor surface.

[0008] The third entrance structure is the second entrance structure, but the automatic door device further comprises a first vertical frame erected at a position where the door edge of the door panel abuts when the door panel is in the closed position covering the doorway, and a second vertical frame erected at a position where the side frame material of the opening away from the first vertical frame is provided, and the opening / closing operation unit is mounted on the first and second vertical frames, and the opening is formed wider than the door panel.

[0009] The fourth entrance structure is the third entrance structure, wherein the automatic door device has at least one side edge in the opening and closing direction of the door panel adjacent to the wall, and the first vertical frame or the second vertical frame is embedded in the wall.

[0010] The fifth entrance structure is any of the second to fourth entrance structures, wherein the automatic door device further has a floor rail that guides the door panel, and the upper end of the floor rail is formed at a height equal to or lower than the floor surface and the outdoor floor surface.

[0011] The sixth entrance structure is any of the first to fifth entrance structures, further comprising a first beam erected above the automatic door device, a second beam parallel to the first beam and erected above the ceiling surface or the outdoor ceiling surface, and a third beam erected above the ceiling surface and perpendicular to the first beam, wherein the depth of the first beam is shorter than that of the second beam and the depths of the first beam and the third beam are equal, and the top surfaces of the first beam, second beam, and third beam are positioned at the same height.

[0012] The seventh entrance structure is any one of the first to sixth entrance structures, wherein the ceiling surface is formed along the automatic door device and has an inspection hatch through which the opening and closing operation unit can be accessed.

[0013] The eighth entrance structure is the fifth entrance structure, with a groove formed between the floor surface and the outdoor floor surface along the outdoor side of the floor rail, the groove having sides and openings at the top and bottom, the groove containing water-permeable granular stone material, and an underground drainage pipe buried below the groove.

[0014] The ninth entrance structure is the eighth entrance structure, wherein the outdoor floor is adjacent to a garden, the trench is connected to the garden, the granular stone is laid in at least the part of the garden connected to the trench, and the culvert drainage pipe is buried below the garden, continuing from below the trench. [Effects of the Invention]

[0015] According to the first entrance structure, the ceiling surface formed indoors and the outdoor ceiling surface are formed adjacent to each other outdoors, and the lower end of the opening and closing operation unit of the sliding door automatic door device is formed at a position higher than the ceiling surface and the outdoor ceiling surface, so the opening and closing operation unit is not exposed below the ceiling surface and the outdoor ceiling surface, the continuity between the indoors and outdoors is not obstructed, and the indoor entrance space and the semi-outdoor space can be created as a space that gives the impression of being connected.

[0016] According to the second entrance structure, the opening has a frame body and a transparent plate that fits into the frame body, and the lower end of the upper frame material of the frame body is equal to or higher than the ceiling surface and outdoor ceiling surface, and the upper end of the lower frame material of the frame body is equal to or lower than the floor surface and outdoor floor surface, so that the space between the ceiling surface and outdoor ceiling surface and the floor surface and outdoor floor surface is made up of transparent plates, creating a space that gives the impression of a more connected indoor entrance space and semi-outdoor space.

[0017] With the third entrance structure, the opening is wider than the door panel, giving the impression that the automatic door system is wider open, creating a more open feeling in the indoor entrance space, creating a space that feels more connected to the semi-outdoor space. Furthermore, by making the opening a different width from the door panel, the entire width of the automatic door system can be greatly increased while still using a standard automatic door mechanism, allowing for greater design freedom.

[0018] According to the fourth entrance structure, the first or second vertical frame is embedded in the wall, so the first or second vertical frame is not visible, enhancing the continuity between indoors and outdoors and creating a more connected impression between the indoor entrance space and the semi-outdoor space.

[0019] According to the fifth entrance structure, the upper end of the floor rail is formed at a height equal to or lower than the floor and outdoor floor surfaces, so it does not obstruct passage through the entrance and exit. Furthermore, because the floor rail is not noticeable, it enhances the continuity between indoors and outdoors, giving the impression that the indoor entrance space and semi-outdoor space are more connected.

[0020] In the sixth entrance structure, the first beam, which is located above the opening and closing unit of the automatic door system, and the third beam, whose end perpendicular to the first beam is located above the opening and closing unit of the automatic door system, have short beam depths, which allows the height of the undersides of the first and third beams to be raised, allowing the opening and closing unit to be placed above the ceiling and outdoor ceiling surfaces without lowering them. Furthermore, the long beam depth of the second beam makes up for the lack of strength caused by the short beam depths of the first and third beams.

[0021] According to the seventh entrance structure, an inspection hatch is formed in the ceiling surface through which the opening and closing operation unit can be accessed, so that the opening and closing operation unit can be easily maintained without removing the ceiling surface.

[0022] According to the eighth entrance structure, a groove is formed between the floor surface and the outdoor floor surface along the floor rail, and water-permeable granular stone is stored in the groove with an underground drainage pipe buried underneath, preventing rainwater and other liquids from entering the indoor entrance space, and the storage of granular stone allows for a more aesthetically pleasing design than a simple drainage ditch or grating cover.

[0023] According to the ninth entrance structure, the ground, paved with granular stone, is connected to the ditch in the garden, and while a drainage ditch is provided to prevent rainwater from entering, the ditch is not noticeable, resulting in a natural and well-designed entrance structure.

DETAILED DESCRIPTION OF THE INVENTION

[0025] Hereinafter, an embodiment of the entrance structure of the present invention will be described with reference to the drawings. The entrance structure 1 is a structure that connects the outdoors and the indoors and is installed in a building 2, such as a house. Note that the building 2 in which the entrance structure 1 is installed is not limited to a house, and the entrance structure 1 can be installed in buildings for various purposes, such as apartment buildings and various facilities.

[0026] First, the overall configuration of the building 2 in which the entrance structure 1 of this embodiment is installed will be described. As shown in FIG. 1 , the building 2 has a substantially square planar shape on the first floor. The first floor of the building 2 has an L-shaped indoor space 25 extending along two sides of the square, with a garden 3 and a semi-outdoor space 4 formed outdoors within these two sides. The indoor space 25 includes a first extension 21 extending along one side, which is provided with a dining / kitchen area (not shown). The indoor space 25 includes a second extension 22 extending along the other side, which is provided with a living room 24. Adjacent to the living room 24, an indoor entrance space 5 is formed at the end of the second extension 22. The indoor space 25 includes a corner 23, which is bent in plan view and connects the first extension 21 and the second extension 22, which is provided with a stairwell and a bathroom (not shown) for accessing the second floor. The second floor of the building 2 includes multiple private rooms and a balcony (not shown). Although the building 2 in this embodiment is two stories high, it is not limited to this and may be a single-story building or a building 2 with three or more stories.

[0027] On the outdoor side of the indoor space 25 on the first floor, a garden 3 is formed so as to face the living room 24 of the first extension portion 21 and second extension portion 22 of the indoor space 25. Part of the garden 3 is paved with decorative gravel granular stone material 18. Note that the granular stone material 18 is not limited to gravel, and may be, for example, chestnut stone, boulders, or crushed stone as long as it is permeable to water such as rainwater. Plants and garden stones are also arranged in the garden 3.

[0028] A row of transparent first windows 26 are installed from floor to ceiling on the exterior wall of the first extension portion 21 facing the garden 3. A first sliding window 26 is formed at the position farthest from the corner 23 among the first windows 26, allowing access to the garden 3 from the indoor space 25. A fixed first window 26 is also formed between the first sliding window 26 and the corner 23. A second transparent window 27 is arranged from floor to ceiling on the exterior wall of the living room 24 of the second extension portion 22 facing the garden 3, and the position of the second window 27 near the corner 23 is a sliding door, allowing access to the garden 3.

[0029] Such first window 26 and second window 27 blur the boundary between indoor space 25 and outdoor garden 3, creating an impression of a unified, expansive space. Furthermore, by providing first window 26 and second window 27, the automatic door device 6 installed adjacent to second window 27 also gives the impression of being a continuous window, and the indoor space 25 of building 2, garden 3, and semi-outdoor space 4 are perceived as a unified, integrated space, improving the design.

[0030] Adjacent to the garden 3 and on the outdoor side of the indoor entrance space 5, a semi-outdoor space 4 with a roof over the eaves is formed, as shown in Figures 2 and 3. The semi-outdoor space 4 includes a piloti 40 that can be used for various purposes, such as an outdoor living room or an outdoor kitchen, and an entrance porch 41, which provides a traffic line from the piloti 40 to the indoor entrance space 5. The outdoor floor surface 42 formed in the semi-outdoor space 4, i.e., the floor of the piloti 40 and the floor of the entrance porch 41, are formed flush with each other to form the outdoor floor surface 42. The entrance structure 1 is a structure formed in a space that includes the indoor entrance space 5 and the semi-outdoor space 4.

[0031] As shown in FIG. 1, the indoor entrance space 5 has an entrance floor 50 and an earthen floor storage area 51. The floor surface 52 of the indoor entrance space 5, i.e., the floor surfaces 52 of the entrance floor 50 and the earthen floor storage area 51, are flush and lower than the floors of the first extension section 21, the corner section 23, and the living room 24. The floor surface 52 is formed by applying a finishing plastering material to the top surface of the earthen floor concrete. The entrance floor 50 is positioned to allow access to the living room 24 and the earthen floor storage area 51, and is positioned adjacent to the entrance porch 41 of the semi-outdoor space 4 to allow access back and forth.

[0032] As shown in Figures 4 and 5, the indoor entrance space 5 has a horizontal ceiling surface 53, and a shed roof (not shown) is formed on top of the ceiling surface 53. The ceiling surface 53 of the indoor entrance space 5 has base furring strips 53b fixed below gypsum boards 53a, and rectangular wooden ceiling decorative materials 53c are attached below that. The ceiling decorative materials 53c are attached in a row with their length direction facing the semi-outdoor space 4. On the outdoor side of the indoor entrance space 5, the shed roof is extended toward the gable side, forming a horizontal outdoor ceiling surface 43, and the semi-outdoor space 4 is formed below that. An automatic door device 6 is formed at the boundary between the indoor entrance space 5 and the semi-outdoor space 4.

[0033] The outdoor ceiling surface 43 of the semi-outdoor space 4 is flush with the ceiling surface 53 of the indoor entrance space 5. Note that a step may be formed between the outdoor ceiling surface 43 and the ceiling surface 53. The outdoor ceiling surface 43 has a base furring strip 43b fixed below gypsum board 43a, and a rectangular outdoor ceiling decorative material 43c made of the same material as the ceiling decorative material 53c attached to the indoor entrance space 5 is attached below that. The outdoor ceiling decorative material 43c is attached side by side with its length facing the indoor entrance. In this way, the ceiling surface 53 of the indoor entrance space 5 and the outdoor ceiling surface 43 of the semi-outdoor space 4 are flush with each other, and the ceiling decorative material 53c and the outdoor ceiling decorative material 43c, which have the same shape and material, are attached in the same direction, creating the impression that the ceiling surface 53 of the indoor entrance space 5 and the outdoor ceiling surface 43 of the semi-outdoor space 4 are continuous. In addition, the fact that the ceiling surface 53 and the outdoor ceiling surface 43 are flush means that there is no difference in level to the extent that at least a person in the indoor entrance space 5 or the semi-outdoor space 4 would recognize that the ceiling surface 53 and the outdoor ceiling surface 43 are on the same plane.

[0034] As shown in Figure 7, the outdoor floor surface 42 of the semi-outdoor space 4, which is made up of the floor of the piloti 40 and the floor of the entrance porch 41, is formed flush with the floor surface 52 of the indoor entrance space 5. There may be a step between the outdoor floor surface 42 and the floor surface 52. The outdoor floor surface 42, like the floor surface 52 of the indoor entrance space 5, is formed by applying a finishing plastering material to the top surface of the concrete floor. In this way, the floor surface 52 of the indoor entrance space 5 and the outdoor floor surface 42 are flush and finished with the same material, so the floor surface 52 of the indoor entrance space 5 and the outdoor floor surface 42 of the semi-outdoor space 4 appear continuous.

[0035] As shown in Figures 4 to 6, the automatic door device 6, located at the boundary between the indoor entrance space 5 and the semi-outdoor space 4, includes a doorway 60 that allows access between the indoor entrance space 5 and the semi-outdoor space 4, a door panel 7 that opens and closes the doorway 60, an opening 8 adjacent to the doorway 60, an opening / closing unit 9 that opens and closes the door panel 7, a floor rail 61 attached to the floor surface 52 to guide the door panel 7, a first vertical frame 62 formed at one side edge of the automatic door device 6, and a second vertical frame 63 formed at the other side edge. A wall 10 is formed on one side edge of the automatic door device 6. The wall 10 forms part of the exterior wall of the building 2 and protrudes toward the outdoors along the side of the entrance porch 41, hiding the entrance porch 41 from outside views. The wall 10 is formed by attaching gypsum boards 10b to multiple pillars 10a, and a stone decorative material 10c is attached to its surface. A pillar 11 is formed on the other side edge of the automatic door device 6. The pillar 11 is sandwiched between the automatic door device 6 and the second window 27 facing the living room 24. The pillar 11 has a pillar main body 11a on the outer periphery of which a pillar decorative material 11b is attached.

[0036] The doorway 60 is formed between the wall 10 and the opening 8. As shown in FIG. 3, when the door panel 7 is in the open position 7b, it connects the semi-outdoor space 4 and the indoor entrance space 5, allowing passage between them. The door panel 7 has a rectangular frame 70 and a transparent glass portion 71 formed inside the rectangular frame 70. As shown in FIGS. 2 and 3, the door panel 7 is movable between a closed position 7a, which covers the doorway 60, and an open position 7b, which opens the doorway 60. When the door panel 7 is in the closed position 7a, the semi-outdoor space 4 is visible through the transparent portion 71 from the indoor entrance space 5 side, and the indoor entrance space 5 is visible from the semi-outdoor space 4 side. As shown in FIGS. 4 and 5, the upper end of the door panel 7 is suspended from an opening / closing unit 9, and the lower end of the door panel 7 is provided with a door roller 72 and guided by a floor rail 61.

[0037] As shown in Figures 5 and 6, the opening 8 adjacent to the doorway 60 comprises a rectangular frame body 80 having an upper frame member 82, a lower frame member 83, and a pair of side frame members 84a, 84b, and a transparent plate 81 fitted into the frame body 80. The frame body 80 is formed so that the lower end of the upper frame member 82 is slightly higher than the height of the ceiling surface 53 and the outdoor ceiling surface 43. As a result, when the opening 8 is viewed from the indoor entrance space 5 and the semi-outdoor space 4, the upper frame member 82 is barely visible, and the ceiling surface 53 and the outdoor ceiling surface 43 are perceived as being connected together. Note that the height of the lower end of the upper frame member 82 may be equal to the height of the ceiling surface 53 and the outdoor ceiling surface 43.

[0038] As shown in FIG. 5 , the frame body 80 is formed such that the upper end of the lower frame member 83 is at the same height as the floor surface 52 and the outdoor floor surface 42. Specifically, the lower frame member 83 is embedded in the concrete floor that forms the floor surface 52, and the height of its upper end is the same as the floor surface 52 and the outdoor floor surface 42. As a result, when the opening 8 is viewed from the indoor entrance space 5 and the semi-outdoor space 4, the lower frame member 83 is barely visible, and the floor surface 52 and the outdoor floor surface 42 are perceived as being connected as a single unit. Note that the height of the upper end of the lower frame member 83 may be lower than the floor surface 52 and the outdoor floor surface 42. In this way, the upper frame member 82 is hidden by the ceiling surface 53 and the outdoor ceiling surface 43, and the lower frame member 83 is hidden by the floor surface 52 and the outdoor floor surface 42, so that the entire opening 8, from the ceiling surface 53 and the outdoor ceiling surface 43 to the floor surface 52 and the outdoor floor surface 42, is perceived as being transparent, and the indoor entrance space 5 and the semi-outdoor space 4 can be made to appear more connected.

[0039] As shown in Figure 6, one side frame member 84a of the opening 8 is provided at a position where it overlaps with the side frame on the door tail 74 side of the rectangular frame 70 of the door panel 7 in the closed position 7a, and overlaps with the frame on the door tip 73 side of the rectangular frame 70 of the door panel 7 in the open position 7b. The other side frame member 84b, provided on the side edge of the opening 8 away from the first vertical frame 62, is embedded in and integrated with the second vertical frame 63 which is embedded in the column decorative material 11b of the column body 11.

[0040] 4 and 5, the opening / closing operation unit 9 suspends the door panel 7 and controls the movement of the door panel 7. The opening / closing operation unit 9 has a drive unit 90 consisting of, for example, an electric motor and a belt that transmits power to drive the door panel 7, a control unit (not shown) that controls the drive of the drive unit 90 based on the detection of a human presence sensor (not shown), an upper rail 91 that suspends the door panel 7 so that it can be moved in the opening and closing direction, and a downward-opening housing 92 that houses these. Note that the configuration of the opening / closing operation unit 9 is not limited to this, and various opening / closing operation units 9 for sliding-door automatic door devices 6 that are arranged above the door panel 7 can be used.

[0041] The lower end of the opening / closing operation unit 9 is formed at a position higher than the ceiling surface 53 and the outdoor ceiling surface 43, and does not hang down from the ceiling surface 53 and the outdoor ceiling surface 43. The lower end of the opening / closing operation unit 9 may be at the same height as the ceiling surface 53 and the outdoor ceiling surface 43. Since the opening / closing operation unit 9 does not hang down below the ceiling surface 53 and the outdoor ceiling surface 43 in this way, the continuity between the indoors and outdoors is not obstructed, and the indoor entrance space 5 and the semi-outdoor space 4 can be made to appear as a connected space.

[0042] The opening / closing operation unit 9 is formed across the entire width of the automatic door device 6, and is installed on the upper ends of the first vertical frame 62 and the second vertical frame 63. In order to open and close the door panel 7, the opening / closing operation unit 9 only needs to be formed from the door leading edge 73 of the door panel 7 in the closed position 7a to the door trailing edge 74 of the door panel 7 in the open position 7b, but in this embodiment, the opening / closing operation unit 9 is extended beyond the movement range of the door panel 7, and is formed up to the position of the other side frame member 84b of the opening 8 where the second vertical frame 63 is provided. This allows the width of the opening 8 to be wider than the width of the door panel 7, and increases the degree of freedom in designing the width of the opening 8.

[0043] An inspection hatch 12 is provided on the ceiling surface 53 on the indoor side of the location where the opening / closing unit 9 is located, allowing access to the opening / closing unit 9. That is, the inspection hatch 12 is formed over the entire length between the first vertical frame 62 and the second vertical frame 63. The inspection hatch 12 is provided with a hatch 13 that closes when inspection is not being performed. The hatch 13 is formed of the same shape and material as the ceiling decorative material 53c of the ceiling surface 53, preventing a decrease in design when the inspection hatch 12 is closed. The inspection hatch 12 is continuously provided for a length of 3 m or more from the first vertical frame 62 to the second vertical frame 63, but the hatch 13 that closes the inspection hatch 12 may be divided into multiple sections, each of which can be opened and closed. A box-shaped space 93 made of gypsum board is formed above the inspection hatch 12, opening to the side of the opening / closing unit 9. An opening / closing part 94 that flips up is formed on the side of the housing of the opening / closing unit 9 facing indoors. The opening / closing part 94 flips up into the box-shaped space 93. When inspecting the opening / closing operation unit 9, the inspection hatch 12 in the ceiling surface 53 is opened, and furthermore, the opening / closing part 94 of the opening / closing operation unit 9 is flipped up, and the inside of the opening / closing operation unit 9 is inspected and maintained.

[0044] As shown in Figure 6, the first vertical frame 62 is embedded in the wall 10. Specifically, it is disposed so as to be embedded in the gypsum board 10b that forms the base of the stone decorative material 10c, inside the stone decorative material 10c that is attached to the surface of the wall 10. A gap is formed in the stone decorative material 10c into which the door edge 73 of the door panel 7 is inserted. The door edge 73 of the door panel 7 in the closed position 7a abuts against the first vertical frame 62. The second vertical frame 63 is embedded in the pillar 11. Specifically, it is housed in a gap formed in the pillar decorative material 11b of the pillar 11, and the surface of the pillar decorative material 11b and the surface of the second vertical frame 63 that faces the inside of the automatic door device 6 are formed flush with each other. The other side frame material 84b of the opening 8 is embedded in and integrated with the second vertical frame 63, and when looking at the opening 8 from the indoor entrance space 5 or the semi-outdoor space 4, the second vertical frame 63 and the side frame material 84b are barely visible, and the transparent plate 81 of the opening 8 appears to protrude directly from the pillar body 11.

[0045] As shown in Figures 4 and 5, the floor rail 61 is formed in a groove shape between the floor surface 52 and the outdoor floor surface 42. A door roller 72 provided at the lower end of the door panel 7 is inserted into the floor rail 61 to guide the door panel 7 in the opening and closing direction. The upper end of the floor rail 61 is formed at a height equal to that of the floor surface 52 and the outdoor floor surface 42. The upper end of the floor rail 61 may also be formed at a lower position than that of the floor surface 52 and the outdoor floor surface 42. In this way, by having the upper end of the floor rail 61 at a height equal to that of the floor surface 52 and the outdoor floor surface 42 or lower than that of the floor surface 52 and the outdoor floor surface 42, it does not obstruct passage through the doorway 60, and the inconspicuous floor rail 61 enhances the continuity between the indoors and outdoors, making the indoor entrance space 5 and the semi-outdoor space 4 appear more connected.

[0046] As shown in Figure 7, a first beam 14 is formed in the ceiling space above the automatic door device 6, running along the width of the automatic door device 6. The first beam 14 is a perimeter beam installed in the ceiling space on the first floor at the boundary between the indoors and outdoors of the building 2. The first beam 14 is installed between a column body 11a formed inside the column body 11 and a column 10a formed inside the wall body 10. The depth of the first beam 14 is shorter than usual to avoid interference with the opening / closing unit 9 of the automatic door device 6 and the box-shaped space 93 above the inspection hatch 12.

[0047] An indoor second beam 15a is formed adjacent to the first beam 14 on the ceiling surface 53, and an outdoor second beam 15b is formed adjacent to the first beam 14 on the outdoor ceiling surface 43. The indoor second beam 15a and the outdoor second beam 15b are each erected on pillars (not shown) parallel to the first beam 14. Note that the "second beam" in the present invention corresponds to the indoor second beam 15a and the outdoor second beam 15b in this embodiment. The beam depths of the indoor second beam 15a and the outdoor second beam 15b are longer than the beam depth of the first beam 14. By lengthening the beam depth of these indoor second beams 15a and outdoor second beams 15b, the reduced strength of the building 2 frame caused by the shorter beam depth of the first beam 14 is compensated for.

[0048] A third beam 16 is erected above the ceiling surface 53, perpendicular to the first beam 14. The third beam 16 is erected on the first beam 14 and the indoor second beam 15a. The beam depth of the third beam 16 is equal to the beam depth of the first beam 14. This allows the third beam 16 to be joined to the side of the first beam 14 without interfering with the box-shaped space 93. The top surfaces of the first beam 14, the indoor second beam 15a, the outdoor second beam 15b, and the third beam 16 are arranged at the same height, and therefore the bottom surfaces of the indoor second beam 15a and the outdoor second beam 15b are arranged so that they are lower than the first beam 14 and the third beam 16.

[0049] As shown in Figures 2 and 4, the entrance porch 41 is disposed facing the entrance 60 of the automatic door device 6. A groove 17 is formed between the outdoor floor surface 42 of the entrance porch 41 and the floor surface 52 of the entrance 60. The groove 17 is formed along the outdoor side of the floor rail 61. The groove 17 has sides formed by the concrete floor of the outdoor floor surface 42 of the entrance porch 41 and the concrete floor of the floor surface 52 of the entrance dirt floor 50, respectively, and is open upward with the ground exposed at the bottom. Granular stone 18 is stored inside the groove 17. The granular stone 18 is, for example, decorative gravel. Note that the granular stone 18 is not limited to gravel and may be pebbles, boulders, crushed stone, etc. The grain size of the granular stone 18 is large enough to allow water, such as rainwater, to pass through. That is, the granular stone 18 can be stored in the groove 17 while leaving gaps through which water can flow. The particle size of the granular stone 18 is not too large so that it can be laid continuously and aesthetically pleasingly from the groove 17 to the garden 3. Granular stone 18 is laid around the perimeter of the entrance porch 41 in the same way as the groove 17. A gap is also formed between the outdoor floor surface 42 of the entrance porch 41 and the outdoor floor surface 42 of the piloti 40, and granular stone 18 is laid in this gap.

[0050] A culvert drain pipe 19 is buried underground below the trench 17. The culvert drain pipe 19 can be a pipe with holes on its outer periphery or a pipe with its outer periphery partially made of mesh fabric. The culvert drain pipe 19 can be any cylindrical pipe that can guide water from its outer periphery to the inside. The outdoor floor surface 42 of the piloti 40 is adjacent to the garden 3. The garden 3 is formed continuously between the opening 8 and the piloti 40 and is also adjacent to the entrance porch 41.

[0051] As shown in Figures 1 and 2, the trench 17 is arranged so as to connect to the garden 3, and granular stone material 18 is laid even in the part of the garden 3 that connects to the trench 17, so that there is no boundary between the trench 17 and the garden 3 when viewed from above. The underdrain drain pipe 19 provided below the trench 17 is buried continuously below the garden 3. Specifically, the underdrain drain pipe 19 extends below the garden 3 along the outdoor side of the opening 8 of the automatic door device 6, the outdoor side of the second window 27 in the living room 24, and the outdoor side of the first window 26 of the first extension part 21, and is connected to a rainwater collection bin, for example.

[0052] By providing the groove 17 between the floor surface 52 of the entrance dirt floor 50 and the outdoor floor surface 42 of the entrance porch 41 in this way, it is possible to prevent rainwater and the like from entering the indoor entrance space 5 through the opening 8, and since the groove 17 contains granular stone material 18 and is connected to the garden 3, the groove 17 is not noticeable, resulting in a natural and well-designed entrance structure 1.

[0053] It goes without saying that the embodiments of the present invention are not limited to the above-described embodiments, and can be modified as appropriate without departing from the scope of the concept of the present invention.

[0054] This specification discloses the following techniques: [Appendix 1] An entrance structure comprising a ceiling surface formed indoors, an outdoor ceiling surface formed outdoors adjacent to the ceiling surface, an indoor entrance space formed below the ceiling surface, and an automatic sliding door device formed at the boundary between the indoor entrance space and the semi-outdoor space formed below the outdoor ceiling surface, wherein the automatic door device has an entrance through which people can enter and exit, an opening adjacent to the entrance, a door panel that can move from a position covering the entrance to a position overlapping the opening, and an opening / closing operation unit that suspends the door panel and controls the movement of the door panel, the lower end of the opening / closing operation unit being formed at a position higher than the ceiling surface and the outdoor ceiling surface.

[0055] According to Appendix 1, the ceiling surface formed indoors and the outdoor ceiling surface formed adjacent to the ceiling surface are formed flush, and the lower end of the opening and closing operation unit of the sliding door automatic door device is formed at a position higher than the ceiling surface and the outdoor ceiling surface, so the opening and closing operation unit is not exposed below the ceiling surface and the outdoor ceiling surface, the continuity between the indoors and outdoors is not obstructed, and the indoor entrance space and the semi-outdoor space can be created as a space that gives the impression of being connected.

[0056] [Appendix 2] The entrance structure of Appendix 1 further comprises a floor surface formed in the indoor entrance space and an outdoor floor surface formed outdoors adjacent to the floor surface, and the opening has a rectangular frame body having an upper frame material, a lower frame material, and a pair of side frame materials, and a transparent plate fitted into the frame body, the lower end of the upper frame material is formed at a height position equal to or higher than the ceiling surface and the outdoor ceiling surface, and the upper end of the lower frame material is formed at a height position equal to or lower than the floor surface and the outdoor floor surface.

[0057] According to Appendix 2, the opening has a frame body and a transparent plate that fits into the frame body, and the lower end of the upper frame material of the frame body is equal to or higher than the ceiling surface and outdoor ceiling surface, and the upper end of the lower frame material of the frame body is equal to or lower than the floor surface and outdoor floor surface, so that the space between the ceiling surface and outdoor ceiling surface and the floor surface and outdoor floor surface is made up of transparent plates, creating a space that gives the impression of a more connected indoor entrance space and semi-outdoor space.

[0058] [Appendix 3] In the entrance structure of Appendix 2, the automatic door device further comprises a first vertical frame erected at a position where the door edge of the door panel abuts when the door panel is in the closed position covering the entrance, and a second vertical frame erected at a position where the side frame material of the opening away from the first vertical frame is provided, the opening / closing operation unit is mounted on the first vertical frame and the second vertical frame, and the opening is formed wider than the door panel.

[0059] According to Appendix 3, the opening is wider than the door panel, giving the impression that the automatic door system is wider open, creating a more open feeling in the indoor entrance space, creating a space that feels more connected to the semi-outdoor space. Also, by making the opening a different width from the door panel, the entire width of the automatic door system can be greatly increased while still using a standard automatic door mechanism, allowing for greater design freedom.

[0060] [Appendix 4] In the entrance structure of Appendix 3, at least one side edge of the automatic door device in the opening and closing direction of the door panel is adjacent to the wall, and the first vertical frame or the second vertical frame is embedded in the wall.

[0061] According to Appendix 4, since the first vertical frame or the second vertical frame is embedded in the wall, the first vertical frame or the second vertical frame is not visible, enhancing the continuity between indoors and outdoors and creating a more connected impression between the indoor entrance space and the semi-outdoor space.

[0062] [Appendix 5] In the entrance structure of Appendix 2, the automatic door device further has a floor rail that guides the door panel, and the upper end of the floor rail is formed at a height equal to or lower than the floor surface and the outdoor floor surface.

[0063] According to Appendix 5, the upper end of the floor rail is formed at a height equal to or lower than the floor and outdoor floor surfaces, so it does not obstruct passage through the entrance and exit. In addition, because the floor rail is not conspicuous, it enhances the continuity between indoors and outdoors, and creates a more connected impression between the indoor entrance space and the semi-outdoor space.

[0064] [Appendix 6] The entrance structure of Appendix 1 is any of the entrance structures 1 to 5, further comprising a first beam erected above the automatic door device, a second beam parallel to the first beam and erected above the ceiling surface or the outdoor ceiling surface, and a third beam erected above the ceiling surface and perpendicular to the first beam, wherein the depth of the first beam is shorter than that of the second beam and the depths of the first beam and the third beam are equal, and the top surfaces of the first beam, second beam, and third beam are positioned at the same height.

[0065] According to Supplementary Note 6, by shortening the depth of the first beam, which is placed above the opening and closing unit of the automatic door device, and the third beam, whose end perpendicular to the first beam will be placed above the opening and closing unit of the automatic door device, it is possible to raise the height of the undersides of the first and third beams, and to fit the opening and closing unit above the ceiling surface and outdoor ceiling surface without lowering them. Furthermore, by lengthening the depth of the second beam, it is possible to compensate for the lack of strength caused by the short depth of the first and third beams.

[0066] [Appendix 7] The entrance structure of Appendix 1 is any one of the entrance structures 1 to 6, wherein the ceiling surface is formed along the automatic door device and has an inspection hatch through which the opening and closing operation unit can be accessed.
