[0004] By the way, the above-described automatic door device requires a rail for suspending a door panel above an entrance and a case for housing a unit for opening and closing drive, and the placement of the case above the upper side of the entrance leads to a decrease in design quality.

[0005] Therefore, an object of the present invention is to provide an entrance structure that gives an impression of continuously connecting the inside and outside while an automatic door device is provided at the entrance.

Means for Solving the Problems

[0006] A first entrance structure that solves the above problems 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 a sliding automatic 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 / exit that can be entered and exited, a door panel that can move between a closed position covering the entrance / exit and an open position opening the entrance / exit, an opening adjacent to the entrance / exit that overlaps with the door panel in the open position, 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 is formed at a position higher than the ceiling surface and the outdoor ceiling surface. The system further comprises 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 and third beams are equal, and the upper surfaces of the first, second, and third beams are at the same height. .

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

[0008] The third entrance structure is the second entrance structure, wherein the automatic door device further comprises a first vertical frame erected at a position where the leading 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 a side frame member is provided on the side of the opening away from the first vertical frame, the opening and closing operation unit is mounted on the first vertical frame and the second vertical frame, and the opening is formed to be 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 end of the door panel in the opening and closing direction 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 an entrance structure of the second to fourth, wherein the automatic door device further includes a floor rail for guiding the door panel, and the upper end of the floor rail is formed at a height equal to the floor surface and the outdoor floor surface, or at a position lower than the floor surface and the outdoor floor surface.

[0012] The sixth entrance structure is the same as the first to fifth entrance structures. In any of the entrance structures, the ceiling surface is formed along the automatic door device and has an inspection opening that allows access to the opening and closing operation unit.

[0013] The seventh entrance structure In the fifth entrance structure, a groove is formed between the floor surface and the outdoor floor surface along the outdoor side of the floor rail, the groove has sides and opens upward and downward, the groove contains water-permeable granular stone material, and an underground drainage pipe is buried below the groove.

[0014] The eighth entrance structure is the seventh entrance structure In this configuration, the outdoor floor surface is adjacent to a garden, the ditch is connected to the garden, the granular stone material is laid in at least the portion of the garden connected to the ditch, and the underground drainage pipe is buried beneath the garden, continuously extending from below the ditch. [Effects of the Invention]

[0015] According to the first entrance structure, the indoor ceiling surface and the outdoor ceiling surface are adjacent to each other and formed outdoors. In the sliding automatic door device, the lower end of the opening and closing operation unit is formed at a position higher than the indoor ceiling surface and the outdoor ceiling surface. Therefore, the opening and closing operation unit is not exposed below the indoor ceiling surface and the outdoor ceiling surface, the continuity between indoor and outdoor spaces is not obstructed, and the indoor entrance space and semi-outdoor space can be made to appear as a connected space. According to the first entrance structure, the short beam depth of the first beam positioned above the opening and closing operation unit of the automatic door device and the short beam depth of the third beam whose end perpendicular to the first beam is also positioned above the opening and closing operation unit of the automatic door device allow the height of the lower surfaces of the first and third beams to be increased, enabling the opening and closing operation unit to be housed above the ceiling surface and the outdoor ceiling surface without lowering the ceiling surface and the outdoor ceiling surface. Furthermore, the long beam depth of the second beam compensates for the lack of strength caused by the short beam depths of the first and third beams.

[0016] According to the second entrance structure, the opening has a frame and a transparent panel fitted into the frame. The lower end of the upper frame member of the frame is equal to or higher than the ceiling surface and the outdoor ceiling surface, and the upper end of the lower frame member of the frame is equal to or lower than the floor surface and the outdoor floor surface. As a result, the space between the ceiling surface and the outdoor ceiling surface and the floor surface and the outdoor floor surface is composed of a transparent panel, creating a space that gives the impression of a more connected indoor entrance space and semi-outdoor space.

[0017] According to the third entrance structure, since the opening is formed wider than the door panel, the automatic door system gives the impression of opening wider, making the indoor entrance space feel more open and connected to the semi-outdoor space. Furthermore, by making the opening a different width from the door panel, the overall width of the automatic door system can be greatly increased while using a general automatic door mechanism, thereby increasing design flexibility.

[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 indoor and outdoor spaces, 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 the same height as the floor surface and the outdoor floor surface, or at a lower position than the floor surface and the outdoor floor surface, so it does not obstruct passage through the entrance and exit, and because the floor rail is not conspicuous, it enhances the continuity between indoors and outdoors, making the indoor entrance space and semi-outdoor space feel more connected.

[0021] Sixth entrance structure According to the specifications, an inspection opening is formed in the ceiling surface that allows access to the opening and closing mechanism, making it possible to easily maintain the opening and closing mechanism without removing the ceiling surface.

[0022] The seventh entrance structureAccording to this, a groove formed along the floor rail is formed between the floor surface and the outdoor floor surface. Granular stone that can permeate water is stored in the groove, and an underground drainage pipe is buried below it. Therefore, it is possible to prevent rainwater and the like from entering the indoor entrance space. Since the granular stone is stored, the design can be improved compared to a simple drainage groove or grating lid.

[0023] Eighth entrance structure According to this, a ground surface covered with granular stone will be connected from the groove to the garden, and while providing a groove for drainage purposes to prevent rainwater intrusion, it is possible to create an entrance structure that is natural and has good design without the groove being noticeable.

Embodiments for Carrying Out the Invention

[0025] Hereinafter, embodiments of the entrance structure of the present invention will be described with reference to each figure. The entrance structure 1 is a structure that connects the outdoor and indoor areas provided in a building 2 such as a house. Note that the building 2 in which the entrance structure 1 is provided is not limited to a house, and the entrance structure 1 can be provided in various types of buildings such as apartment houses and various facilities.

[0026] First, the general overall configuration of the building 2 in which the entrance structure 1 of this embodiment is provided will be described. As shown in Figure 1, the plan shape of the first floor of building 2 is approximately square. The first floor of building 2 has an L-shaped indoor space 25 that extends along two sides of the square, and a garden 3 and a semi-outdoor space 4 are formed outdoors on the inside of these two sides. In the indoor space 25, a first extension 21 extending in the direction of one side is provided, although it is not shown, for example, as a dining kitchen. In the indoor space 25, a living room 24 is formed in a second extension 22 extending in the direction of the other side, and further adjacent to the living room 24, an indoor entrance space 5 is formed at the end of the second extension 22. In the indoor space 25, a corner 23 that bends in plan view connecting the first extension 21 and the second extension 22 is provided, although it is not shown, for example, as a stairwell for accessing the second floor and a bathroom. The second floor of building 2 is not shown, but it has multiple private rooms and a balcony. Although 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 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 rooms 24 of the first extension 21 and second extension 22 of the indoor space 25. Part of the garden 3 is covered with granular decorative gravel 18. The granular stone material 18 is not limited to gravel; for example, it may be crushed stone, pebbles, or other materials that can permeate water such as rainwater. In addition, plants and garden stones are also placed in the garden 3.

[0028] On the exterior wall of the first extension 21 facing the garden 3, transparent first windows 26 are installed in a row from floor to ceiling. A sliding first window 26 is formed at the position furthest from the corner 23, allowing access to the garden 3 from the indoor space 25. A fixed first window 26 is formed between the sliding first window 26 and the corner 23. In addition, on the exterior wall of the living room 24 of the second extension 22 facing the garden 3, a transparent second window 27 is positioned from floor to ceiling, and the part of the second window 27 closest to the corner 23 is a sliding door, allowing access to the garden 3.

[0029] Such first windows 26 and second windows 27 blur the boundary between the indoor space 25 and the outdoor garden 3, creating a unified and expansive space. Furthermore, the presence of the first windows 26 and second windows 27 gives the impression that the automatic door device 6, which is installed adjacent to the second window 27, is also a continuous window. This allows the indoor space 25 of the building 2, the garden 3, and the semi-outdoor space 4 to be perceived as a unified and integrated space, thereby improving the aesthetic appeal.

[0030] Adjacent to the garden 3, and on the outdoor side of the indoor entrance space 5, a semi-outdoor space 4 covered by an overhanging roof 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 outdoor kitchen, and an entrance porch 41 that serves as a passageway from the piloti 40 to the indoor entrance space 5. The outdoor floor surface 42 formed in the semi-outdoor space 4, that is, the floor of the piloti 40 and the floor of the entrance porch 41, are formed flush with each other. The entrance structure 1 is a structure formed in the space including the indoor entrance space 5 and the semi-outdoor space 4.

[0031] As shown in Figure 1, the indoor entrance space 5 has an entrance floor 50 and a storage area 51. The floor surface 52 of the indoor entrance space 5, i.e., the floor surface 52 of the entrance floor 50 and the storage area 51, is flush with the floor and is lower than the first extension 21, the corner 23, and the floor of the living room 24. The floor surface 52 is formed by applying a finishing plaster material to the top surface of the concrete floor. The entrance floor 50 is positioned to provide access to the living room 24 and the storage area 51, and is also positioned adjacent to the entrance porch 41 of the semi-outdoor space 4, allowing access to both.

[0032] As shown in Figures 4 and 5, the indoor entrance space 5 has a horizontal ceiling surface 53, and above the ceiling surface 53 is a single-slope roof (not shown). The ceiling surface 53 of the indoor entrance space 5 has a base furring strip 53b fixed beneath a gypsum board 53a, and below that, rectangular wooden ceiling trim 53c is attached. The ceiling trim 53c is attached in a row so that its length faces the semi-outdoor space 4. On the outdoor side of the indoor entrance space 5, the single-slope roof extends to the gable end, forming a horizontal outdoor ceiling surface 43, below which the semi-outdoor space 4 is formed. 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 formed flush with the ceiling surface 53 of the indoor entrance space 5. However, there may be a step between the outdoor ceiling surface 43 and the ceiling surface 53. On the outdoor ceiling surface 43, a base furring strip 43b is fixed beneath the gypsum board 43a, and below that, 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, and the outdoor ceiling decorative material 43c is attached in a row so that its length faces 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, and the ceiling decorative material 53c and outdoor ceiling decorative material 43c of the same shape and material are attached in the same orientation, so that the ceiling surface 53 of the indoor entrance space 5 and the outdoor ceiling surface 43 of the semi-outdoor space 4 give the impression of continuity. Furthermore, the statement 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 perceive the ceiling surface 53 and the outdoor ceiling surface 43 as being on the same plane.

[0034] As shown in Figure 7, the outdoor floor surface 42 of the semi-outdoor space 4, which consists 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. Note that there may be a step between the outdoor floor surface 42 and the indoor entrance space 52. The outdoor floor surface 42 is formed by applying a finishing plaster material to the top surface of the concrete slab, similar to the indoor entrance space 5's floor surface 52. Thus, since the indoor entrance space 5's floor surface 52 and the outdoor floor surface 42 are flush and finished with the same material, the indoor entrance space 5's floor surface 52 and the semi-outdoor space 4's outdoor floor surface 42 give the impression of continuity.

[0035] As shown in Figures 4 to 6, the automatic door device 6 formed at the boundary between the indoor entrance space 5 and the semi-outdoor space 4 includes an entrance / exit 60 that allows entry and exit between the indoor entrance space 5 and the semi-outdoor space 4, a door panel 7 that opens and closes the entrance / exit 60, an opening 8 positioned adjacent to the entrance / exit 60, an opening / closing operation unit 9 that opens and closes the door panel 7, a floor rail 61 provided on the floor surface 52 to guide the door panel 7, a first vertical frame 62 formed on one side end of the automatic door device 6, and a second vertical frame 63 formed on the other side end. A wall body 10 is formed on one side edge of the automatic door device 6. The wall body 10 forms part of the exterior wall of the building 2 and protrudes outward along the side edge of the entrance porch 41, concealing the entrance porch 41 from view from the outside. The wall body 10 is formed by attaching gypsum board 10b to a plurality of columns 10a, and a stone decorative material 10c is attached to its surface. A column 11 is formed on the other side edge of the automatic door device 6. The column 11 is formed between the second window 27 facing the living room 24 and the automatic door device 6. A decorative column material 11b is attached to the outer circumference of the column body 11a of the column 11.

[0036] The entrance / exit 60 is formed between the wall 10 and the opening 8, and as shown in Figure 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 section 71 formed inside the rectangular frame 70. As shown in Figures 2 and 3, the door panel 7 is movable between a closed position 7a that covers the entrance / exit 60 and an open position 7b that opens the entrance / exit 60. In the closed position 7a, the semi-outdoor space 4 is visible from the indoor entrance space 5 side through the transparent section 71, and the indoor entrance space 5 is visible from the semi-outdoor space 4 side. As shown in Figures 4 and 5, the upper end of the door panel 7 is suspended from the opening / closing operation unit 9, and the lower end of the door panel 7 is guided by a floor rail 61 with a roller 72.

[0037] As shown in Figures 5 and 6, the opening 8 adjacent to the entrance 60 has a rectangular frame 80 having an upper frame member 82, a lower frame member 83, and a pair of side frame members 84a and 84b, and a transparent plate 81 fitted into the frame 80. The lower end of the upper frame member 82 of the frame 80 is formed to be 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 hardly visible, and the ceiling surface 53 and the outdoor ceiling surface 43 are perceived as a single connected unit. 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 Figure 5, the frame 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 slab forming the floor surface 52, and the height of its upper end is equal to that of the floor surface 52 and the outdoor floor surface 42. As a result, when viewing the opening 8 from the indoor entrance space 5 and the semi-outdoor space 4, the lower frame member 83 is hardly visible, and the floor surface 52 and the outdoor floor surface 42 are perceived as a single, continuous space. The height of the upper end of the lower frame member 83 may be lower than that of 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 transparent, making the indoor entrance space 5 and the semi-outdoor space 4 appear as a more connected space.

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

[0040] As shown in Figures 4 and 5, the opening / closing operation unit 9 suspends the door panel 7 and controls its movement. The opening / closing operation unit 9 includes a drive unit 90 consisting of, for example, an electric motor and a belt for transmitting power to drive the door panel 7, a control unit (not shown) that controls the drive of the drive unit 90 based on detection by a human presence sensor (not shown), an upper rail 91 that suspends the door panel 7 so as to be movable in the opening and closing direction, and a downward-opening housing 92 that houses these components. The configuration of the opening / closing operation unit 9 is not limited to this, and various opening / closing operation units 9 of a sliding automatic door device 6 can be used, positioned above the door panel 7.

[0041] The lower end of the opening / closing operation unit 9 is positioned 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. Alternatively, 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. By ensuring that the opening / closing operation unit 9 does not hang down below the ceiling surface 53 and the outdoor ceiling surface 43, the continuity between the indoor and outdoor spaces 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 leading edge 73 of the door panel 7 in the closed position 7a to the trailing edge 74 of the door panel 7 in the open position 7b. However, in this embodiment, the opening / closing operation unit 9 is extended beyond the range of movement 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 makes the width of the opening 8 wider than the width of the door panel 7, thereby increasing the design flexibility of the width of the opening 8.

[0043] On the indoor side of the location where the opening / closing operation unit 9 is formed, an inspection opening 12 is provided in the ceiling surface 53, allowing access to the opening / closing operation unit 9. Specifically, the inspection opening 12 extends along the entire length between the first vertical frame 62 and the second vertical frame 63. The inspection opening 12 is provided with a hatch 13 that closes when not being inspected. The hatch 13 is made of the same material and has the same shape as the ceiling decorative material 53c of the ceiling surface 53, thus minimizing any decrease in aesthetic appeal when the inspection opening 12 is closed. The inspection opening 12 extends continuously for more than 3m from the first vertical frame 62 to the second vertical frame 63, but the hatch 13 that closes the inspection opening 12 may be divided into multiple sections, each of which can be opened and closed. Above the inspection opening 12, a box-shaped space 93 made of gypsum board is formed, opening to the side of the opening / closing operation unit 9. On the indoor-facing side of the housing of the opening / closing operation unit 9, an opening / closing part 94 that flips up is formed. 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 on the ceiling surface 53 is opened, and the opening / closing part 94 of the opening / closing operation unit 9 is then flipped up to inspect and maintain the inside of the opening / closing operation unit 9.

[0044] The first vertical frame 62 is embedded in the wall 10, as shown in Figure 6. Specifically, it is positioned to be embedded in the gypsum board 10b that serves as the base for the stone decorative material 10c, which is attached to the surface of the wall 10. A gap is formed in the stone decorative material 10c into which the leading edge 73 of the door panel 7 is inserted. The leading 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 column 11. Specifically, it is housed in a gap provided in the column decorative material 11b of the column 11, and the surface of the column decorative material 11b and the surface of the second vertical frame 63 facing inward towards the automatic door device 6 are formed flush. The second vertical frame 63 is integrated with the other side frame member 84b of the opening 8, and when the opening 8 is viewed from the indoor entrance space 5 or the semi-outdoor space 4, the second vertical frame 63 and the side frame member 84b are hardly visible, and the transparent panel 81 of the opening 8 appears to protrude directly from the column 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. The floor rail 61 guides the door panel 7 in the opening and closing direction, with the door roller 72, which is provided at the lower end of the door panel 7, being inserted into the floor rail 61. The upper end of the floor rail 61 is formed at the same height as the floor surface 52 and the outdoor floor surface 42. However, the upper end of the floor rail 61 may be formed at a lower position than the floor surface 52 and the outdoor floor surface 42. In this way, by having the upper end of the floor rail 61 at the same height as the floor surface 52 and the outdoor floor surface 42, or at a lower height than the floor surface 52 and the outdoor floor surface 42, it does not obstruct passage through the entrance 60, and the floor rail 61 is inconspicuous, thereby enhancing the continuity between the indoor and outdoor spaces and creating a more connected impression between the indoor entrance space 5 and the semi-outdoor space 4.

[0046] As shown in Figure 7, a first beam 14 is formed in the ceiling space above the automatic door device 6, extending along the width direction of the automatic door device 6. The first beam 14 is an outer perimeter beam provided in the ceiling space of the first floor at the boundary between the indoor and outdoor areas of the building 2. The first beam 14 is erected between the column body 11a formed inside the column body 11 and the column 10a formed inside the wall body 10. The first beam 14 has a shorter beam depth than usual to avoid interference with the opening and closing operation unit 9 and the box-shaped space 93 above the inspection hatch 12 of the automatic door device 6.

[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 columns (not shown) parallel to the first beam 14. In this embodiment, the "second beam" refers to the indoor second beam 15a and the outdoor second beam 15b, respectively. 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 increasing the beam depth of these indoor second beams 15a and the outdoor second beams 15b, they compensate for the reduction in the strength of the building structure 2 caused by the shortened beam depth of the first beam 14.

[0048] A third beam 16 is erected above the ceiling surface 53, perpendicular to the first beam 14. The third beam 16 is supported by the first beam 14 and the indoor second beam 15a. The beam depth of the third beam 16 is equal to that 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 upper surfaces of the first beam 14, the indoor second beam 15a, the outdoor second beam 15b, and the third beam 16 are at the same height, and therefore the lower surfaces of the indoor second beam 15a and the outdoor second beam 15b are positioned lower than those of the first beam 14 and the third beam 16.

[0049] As shown in Figures 2 and 4, the entrance porch 41 is positioned 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 sides of the groove 17 are formed by the concrete slab of the outdoor floor surface 42 of the entrance porch 41 and the concrete slab of the floor surface 52 of the entrance floor 50, respectively, and it opens upwards, with the ground exposed at the bottom. Granular stone material 18 is stored inside the groove 17. The granular stone material 18 is, for example, decorative gravel. Note that the granular stone material 18 is not limited to gravel, but may also be rubble, pebbles, crushed stone, etc. The granular stone material 18 has a particle size large enough to allow sufficient water such as rainwater to pass through, that is, the granular stone material 18 can be stored in the groove 17 while leaving gaps for water to flow through. Furthermore, the granular stone material 18 has a particle size that is not too large so that it can be laid continuously from the groove 17 to the garden 3 in a manner that is aesthetically pleasing. The granular stone material 18 is laid around the outer 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 the granular stone material 18 is laid in this gap as well.

[0050] A drainage pipe 19 is buried underground below the trench 17. The drainage pipe 19 can be a pipe with holes on its outer surface or a pipe whose outer surface is partially made of mesh fabric. The drainage pipe 19 only needs to be cylindrical in shape so that water can be guided into the interior from its outer surface. 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 positioned to connect to the garden 3, and granular stone material 18 is laid in the portion of the garden 3 connected to the trench 17, so that there is no boundary between the trench 17 and the garden 3 when viewed from above. The underground drainage pipe 19, located below the trench 17, is continuously buried below the garden 3. Specifically, the underground drainage 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 of the living room 24, and the outdoor side of the first window 26 of the first extension 21, and is connected to, for example, a rainwater collection manhole.

[0052] By providing the groove 17 between the floor surface 52 of the entrance porch 50 and the outdoor floor surface 42 of the entrance porch 41, it is possible to prevent rainwater and other liquids from entering the indoor entrance space 5 through the opening 8. Furthermore, since the groove 17 contains granular stone material 18 and connects to the garden 3, the groove 17 is not consciously noticed, resulting in a natural and aesthetically pleasing entrance structure 1.

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

[0054] This specification discloses the following technologies: [Note 1] The structure comprises an indoor ceiling surface, an outdoor ceiling surface adjacent to the indoor ceiling surface, an indoor entrance space formed below the indoor ceiling surface, and a sliding automatic door device formed at the boundary between the indoor and outdoor spaces formed below the outdoor ceiling surface. The automatic door device includes an entrance / exit that allows entry and exit, a door panel that can move between a closed position covering the entrance / exit and an open position opening the entrance / exit, an opening adjacent to the entrance / exit that overlaps with the door panel in the open position, and an opening / closing operation unit that suspends the door panel and controls its movement. The lower end of the opening / closing operation unit is formed at a position higher than the indoor ceiling surface and the outdoor ceiling surface. The system further comprises 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 and third beams are equal, and the upper surfaces of the first, second, and third beams are at the same height. Entrance structure.

[0055] According to Appendix 1, the indoor ceiling surface and the outdoor ceiling surface adjacent to the indoor ceiling surface are formed flush with each other, and the lower end of the sliding automatic door device's opening and closing operation unit is formed higher than the indoor ceiling surface and the outdoor ceiling surface. As a result, the opening and closing operation unit is not exposed below the indoor ceiling surface and the outdoor ceiling surface, the continuity between indoor and outdoor spaces is not obstructed, and the indoor entrance space and semi-outdoor space can be made to appear as a connected space. According to Appendix 1, the short beam depth of the first beam positioned above the opening and closing operation unit of the automatic door device, and the short beam depth of the third beam whose end perpendicular to the first beam is positioned above the opening and closing operation unit of the automatic door device, allows the height of the underside of the first and third beams to be increased, enabling the opening and closing operation unit to be housed above the ceiling surface and the outdoor ceiling surface without lowering the ceiling surface and the outdoor ceiling surface. Furthermore, the long beam depth of the second beam compensates for the insufficient strength caused by the short beam depths of the first and third beams.

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

[0057] According to Appendix 2, the opening has a frame and a transparent panel fitted into the frame. The lower end of the upper frame member of the frame is equal to or higher than the ceiling surface and the outdoor ceiling surface, and the upper end of the lower frame member of the frame is equal to or lower than the floor surface and the outdoor floor surface. As a result, the space between the ceiling surface and the outdoor ceiling surface and the floor surface and the outdoor floor surface is composed of a transparent panel, creating a space that gives the impression of a more connected indoor entrance space and semi-outdoor space.

[0058] [Note 3] In the entrance structure described in Appendix 2, the automatic door device further comprises a first vertical frame erected at a position where the leading 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 a side frame member is provided on the side of the opening away from the first vertical frame, the opening and closing operation unit is mounted on the first vertical frame and the second vertical frame, and the opening is formed to be wider than the door panel.

[0059] According to Appendix 3, since the opening is wider than the door panel, the automatic door system gives the impression of opening wider, making the indoor entrance space feel more open and connected to the semi-outdoor space. Furthermore, by making the opening a different width from the door panel, the overall width of the automatic door system can be greatly increased while using a typical automatic door mechanism, thereby increasing design flexibility.

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