[Figure 3] FIG. 2 is a cross-sectional view taken along line II-II in FIG. [Figure 4] FIG. 2 is a front view of a modified example of the entrance structure shown in FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, embodiments of an entrance structure and a building according to the present invention will be described with reference to the drawings. In each drawing, the same components are designated by the same reference numerals.

[0021] Fig. 1 is a front view of an entrance structure 100 as one embodiment of the entrance structure according to the present invention. Fig. 2 is a cross-sectional view of the entrance structure 100 taken along line II in Fig. 1. Fig. 3 is a cross-sectional view of the entrance structure 100 taken along line II-II in Fig. 1.

[0022] The entrance structure 100 comprises a wall portion 1, a frame body 2, and a door 3.

[0023] The wall portion 1 defines an entrance 1a. The frame body 2 is disposed at the entrance 1a. The door 3 is attached to the frame body 2. The door 3 is configured to be able to open and close the entrance 1a. The door 3 in this embodiment is a single swing door.

[0024] The wall 1 of this embodiment is an exterior wall 202 of a building 200. First, an overview of the building 200 of this embodiment will be described. The building 200 may be, for example, a two-story detached house with a steel frame. The building 200 of this embodiment includes a foundation structure and a superstructure as a structural frame 210. The foundation structure may be, for example, a reinforced concrete continuous footing supported on the ground. The superstructure is supported by the foundation structure and has a framework composed of framework members, such as vertical frame members 30 (see FIG. 2) such as pillars and studs, and horizontal frame members 40 (see FIG. 3) such as beams, lintels, and window sills. The framework members that make up the framework may be standardized members that are manufactured in a factory and then transported to a construction site and assembled. However, the building 200 may also be a wooden house constructed using a conventional construction method. The building 200 is not limited to being two-story, but may have one or three or more floors. Furthermore, the building 200 is not limited to a detached house, but may be, for example, an apartment building.

[0025] The upper structure serving as the structural skeleton 210 of the building 200 of this embodiment includes a wall 1 that defines the entrance 1a. The wall 1 of this embodiment includes a plurality of vertical frame members 30, a plurality of horizontal frame members 40 installed between these vertical frame members 30, and wall elements supported by the vertical frame members 30 and the horizontal frame members 40. In addition to the above-mentioned wall 1, the upper structure serving as the structural skeleton 210 of the building 200 of this embodiment also includes a floor supported by the horizontal frame members 40 of the framework, and a roof covering the upper part of the framework. In other words, the structural skeleton 210 of the building 200 of this embodiment includes the wall 1, floor, and roof of the above-mentioned upper structure.

[0026] The wall portion 1 is provided on the outer periphery of the frame and includes an exterior wall 202 that separates the outdoor space and the indoor space of the building 200, and a partition wall that is provided inside the frame and separates the indoor spaces of the building 200. As described above, Fig. 1 shows an entrance / exit structure 100 formed at the position of the exterior wall 202 of the wall portion 1. Fig. 1 is a front view of the entrance / exit structure 100 as seen from the outdoor side.

[0027] As shown in Figures 1 to 3, the exterior wall 202 as the wall portion 1 of this embodiment includes a first vertical frame member 30a and a second vertical frame member 30b as vertical frame members 30, an upper horizontal frame member 40a and a lower horizontal frame member 40b as horizontal frame members 40, and a wall panel material 203, a heat insulating material 204, and an interior material 205 as wall elements.

[0028] As shown in Figures 1 to 3, the outdoor surface of the exterior wall 202 is made up of exterior wall panels that serve as connected wall panel members 203. Also, as shown in Figures 2 and 3, a heat insulating material 204 and an interior material 205 that form a heat insulating layer are arranged on the indoor side of the wall panel member 203 of the exterior wall 202. The interior material 205 of this embodiment includes an interior wall material 205a that covers the indoor side of the heat insulating material 204 in the projected width direction A of the frame body 2, which is the thickness direction of the wall section 1, and an interior frame material 205b that covers the entrance / exit 1a side of the heat insulating material 204 in the projected width direction B of the frame body 2.

[0029] The exterior wall panel serving as the wall panel member 203 can be, for example, a lightweight aerated concrete (hereinafter referred to as "ALC." "ALC" is an abbreviation for "autoclaved lightweight concrete") panel, metal or ceramic siding, extruded cement board, wood panel, etc. By connecting the exterior wall panel serving as the wall panel member 203 around the outer periphery of the frame, the outer skin layer of the exterior wall 202 can be formed.

[0030] The insulating material 204 may be, for example, a panel-shaped insulating material made of a foamed resin material such as phenolic foam, polystyrene foam, or urethane foam, or a fibrous insulating material such as rock wool. By arranging the insulating material 204 on the indoor side of the wall panel member 203 along the inner surface of the wall panel member 203, an insulating layer can be formed in the exterior wall 202. For example, gypsum board can be used as the interior wall material 205a of the interior material 205, and an inner skin layer can be formed by connecting the interior wall material 205a to the indoor side of the outer periphery of the frame. For example, a wooden frame can be used as the interior frame material 205b of the interior material 205, and by connecting the interior wall material 205a to the interior wall material 205a, an inner skin layer can be formed together with the interior wall material 205a.

[0031] The floor may include, for example, a floor slab material. The floor slab material is installed between beams serving as horizontal frame members 40 of the frame, and is supported directly or indirectly by the beams. For example, ALC panels can be used as the floor slab material, but other materials such as folded plates, extruded cement boards, and wood panel materials may also be used. The floor may also be a dirt floor.

[0032] The roof may be, for example, a flat roof. The roof floor slab material that constitutes the flat roof may be made of ALC panels, but is not limited to ALC panels. Furthermore, the roof is not limited to a flat roof, and may be a sloped roof using roof exterior materials such as slate.

[0033] Next, a description will be given of the details of the entrance structure 100. As described above, the entrance structure 100 comprises the wall portion 1, the frame body 2, and the door 3.

[0034] <Wall part 1> As described above, the entrance 1a of this embodiment is an entrance formed at the position of the exterior wall 202 and allows access between the indoor space and the outdoor space. However, the entrance 1a may also be an entrance formed at the position of a partition wall inside the building 200, for example.

[0035] As shown in Figures 1 to 3, the entrance / exit 1a of this embodiment is defined by a first vertical frame member 30a, a second vertical frame member 30b, an upper horizontal frame member 40a, a lower horizontal frame member 40b, a wall panel member 203, a heat insulating material 204, and an interior frame member 205b of an interior material 205 in an exterior wall 202 as a wall portion 1.

[0036] The upper horizontal frame member 40a and the lower horizontal frame member 40b extend horizontally in the width direction B of the frame body 2. The first vertical frame member 30a and the second vertical frame member 30b extend vertically in the vertical direction C and are attached to the upper horizontal frame member 40a and the lower horizontal frame member 40b.

[0037] The first vertical frame member 30a and the second vertical frame member 30b may be, for example, pillars, studs, or the like fixed to the upper and lower beams of the floor where the entrance 1a of the building 200 is located. The first vertical frame member 30a and the second vertical frame member 30b in this embodiment have the same cross-sectional shape. Specifically, as shown in FIG. 2 , the first vertical frame member 30a and the second vertical frame member 30b in this embodiment are each made of angle iron. However, the first vertical frame member 30a and the second vertical frame member 30b are not limited to this configuration. The first vertical frame member 30a and the second vertical frame member 30b may each be made of other cross-sectional shapes, such as H-shaped steel, C-shaped steel, channel steel, or square steel. Furthermore, if the building 200 is made of wood, the first vertical frame member 30a and the second vertical frame member 30b may each be made of wooden pillars.

[0038] As shown in FIG. 3 , the upper portion of the doorway 1a of this embodiment includes wall panels 203, thermal insulation 204, and interior wall material 205a. Therefore, the upper horizontal frame member 40a of this embodiment is formed by a lintel fixed to the first vertical frame member 30a and the second vertical frame member 30b. However, if the upper portion of the doorway 1a does not include wall panels 203, thermal insulation 204, and interior wall material 205a, the upper horizontal frame member 40a may be, for example, an upper beam of the floor on which the doorway 1a of the building 200 is located. As shown in FIG. 3 , the upper horizontal frame member 40a of this embodiment is formed by angle iron, but is not limited to this configuration. The upper horizontal frame member 40a may also be formed by other cross-sectional shapes, such as H-shaped steel, C-shaped steel, channel steel, or square steel. Furthermore, if the building 200 is made of wood, the upper horizontal frame member 40a may be formed by wooden beams.

[0039] The lower horizontal frame member 40b of this embodiment is formed by a lower beam of the floor where the entrance 1a of the building 200 is located. The lower beam serving as the lower horizontal frame member 40b of this embodiment is fixed to the first vertical frame member 30a and the second vertical frame member 30b. Although the lower horizontal frame member 40b of this embodiment is formed by an H-shaped steel, this configuration is not limited thereto. The lower horizontal frame member 40b may be formed by a configuration having another cross-sectional shape, such as an angle steel, a C-shaped steel, a channel steel, or a square steel. Furthermore, if the building 200 is made of wood, the lower horizontal frame member 40b may be formed by a wooden beam.

[0040] The upper horizontal frame member 40a may be fixed to the first vertical frame member 30a and the second vertical frame member 30b using fastening members such as bolts or screws, or may be fixed by welding metal materials together. The lower horizontal frame member 40b may be fixed to the first vertical frame member 30a and the second vertical frame member 30b using fastening members such as bolts, or may be fixed by welding metal materials together.

[0041] In this way, the doorway 1a of this embodiment is defined by the first vertical frame members 30a, the second vertical frame members 30b, the upper horizontal frame members 40a, and the lower horizontal frame members 40b in addition to the wall elements of the wall panel members 203, the insulating material 204, and the interior frame members 205b. This increases the strength of the area around the doorway 1a compared to a doorway defined only by the wall elements of the wall panel members 203, the insulating material 204, and the interior frame members 205b. However, in the doorway structure according to the present invention, the first vertical frame members 30a and the second vertical frame members 30b may be omitted under certain conditions. This will be described in more detail later (see FIG. 4).

[0042] <Frame 2 and door 3> As shown in Fig. 1, a frame body 2 is placed at a doorway 1a. As shown in Figs. 1 to 3, a door 3 is attached to the frame body 2 and configured to be able to open and close the doorway 1a.

[0043] The door 3 of this embodiment is a single-wing door in which the end portion on one side in the width direction of the door base (hereinafter referred to as the "door base end portion") is rotatably attached to the frame body 2 by a hinge 3f or the like. As a result, the door 3 can rotate relative to the frame body 2 with the door base end portion as the rotation center axis.

[0044] As shown in FIGS. 2 and 3 , the door 3 of this embodiment includes a first panel 3a and a second panel 3b constituting both sides of the door 3 in the thickness direction; a frame member 3c extending between the outer edges of the first panel 3a and the second panel 3b along the outer edges of the first panel 3a and the second panel 3b and sandwiched between the outer edges of the first panel 3a and the second panel 3b; and an insulating material 3d disposed within the frame member 3c between the first panel 3a and the second panel 3b. The first panel 3a and the second panel 3b may be made of metal, such as aluminum, stainless steel, or steel. The frame member 3c may be made of metal or resin. The insulating material 3d may be a panel-shaped insulating material made of a foamed resin material, such as phenolic foam, polystyrene foam, or urethane foam.

[0045] As described above, in the outer edge portion 3e of the door 3 of this embodiment, no insulating material 3d is disposed between the first face member 3a and the second face member 3b, and instead, the skeleton frame member 3c is sandwiched between them. Therefore, the outer edge portion 3e of the door 3 of this embodiment, which includes the upper end, lower end, door base end, and the end on the door tip side on the other side in the width direction (hereinafter referred to as the "door tip"), has a higher thermal conductivity in the thickness direction than the central portion of the door 3. However, the configuration of the door 3 is not limited to this configuration. The configuration of the door 3 is not particularly limited as long as it is attached to the frame body 2 and can open and close the doorway 1a. As will be described in detail later, the doorway structure according to the present invention can prevent the formation of a thermal bridge at the outer edge portion 3e of the door 3, even when a door 3 having a higher thermal conductivity in the thickness direction at the outer edge portion 3e than at the central portion is used, as in this embodiment.

[0046] The frame body 2 is provided with a resin covering portion 50 that covers the outer edge portion 3e of the door 3 in the closed state from the projection width direction A of the frame body 2. Specifically, as shown in FIGS. 2 and 3 , the covering portion 50 of this embodiment includes a door tip covering portion 51 that covers the door tip portion as the outer edge portion 3e of the door 3 from the projection width direction A, a door base covering portion 52 that covers the door base end portion as the outer edge portion 3e of the door 3 from the projection width direction A, and an upper end covering portion 53 that covers the upper end portion as the outer edge portion 3e of the door 3 from the projection width direction A. The covering portion 50 may further include a lower end covering portion that covers the lower end portion as the outer edge portion 3e of the door 3 from the projection width direction A. Examples of materials that can be used for the resin covering portion 50 include vinyl chloride, which is the material that forms the frame body 2.

[0047] Specifically, the frame body 2 of this embodiment includes vertical frames 10a, 10b on both sides extending in the vertical direction C, and upper and lower horizontal frames 20a, 20b extending in the horizontal direction B. The upper and lower horizontal frames 20a, 20b connect the vertical frames 10a, 10b on both sides. More specifically, the upper horizontal frame 20a is fixed to the upper ends of the vertical frames 10a, 10b on both sides. The lower horizontal frame 20b is fixed to the lower ends of the vertical frames 10a, 10b on both sides. The vertical frames 10a, 10b, the upper horizontal frame 20a, and the lower horizontal frame 20b on both sides may each be made of a resin material such as polyvinyl chloride. In other words, the frame body 2 may be a resin frame. Furthermore, the vertical frames 10a, 10b, the upper horizontal frame 20a, and the lower horizontal frame 20b on both sides may each be made of, for example, both a metal material such as aluminum and a resin material such as polyvinyl chloride. In other words, the frame body 2 may be a composite frame containing both metal and resin. The upper horizontal frame 20a and each of the vertical frames 10a, 10b on both sides may be fixed to each other using fastening members such as bolts and screws, or may be fixed by welding metal materials together. The lower horizontal frame 20b and each of the vertical frames 10a, 10b on both sides may be fixed to each other using fastening members such as bolts and screws, or may be fixed by welding metal materials together. For ease of explanation, in the following description, when the entrance structure 100 is viewed from the front from the outdoor side (see FIG. 1), the vertical frame 10a located on the left side will be referred to as the "first vertical frame 10a," and the other vertical frame 10b located on the right side will be referred to as the "second vertical frame 10b."

[0048] As shown in FIG. 2, the first vertical frame 10a of this embodiment includes an aluminum first vertical frame body 10a1 with an endless portion 11a and a resin covering portion 50, which is a door base covering portion 52, connected to the first vertical frame body 10a1. As shown in FIG. 2, the first vertical frame body 10a1 is positioned adjacent to the door 3 in the closed state in the projected width direction B. In contrast, as shown in FIG. 2, the door base covering portion 52 is positioned adjacent to the door base end portion, which serves as the outer edge 3e of the door 3 in the closed state, in the projected width direction A. The entrance structure 100 of this embodiment includes a rubber seal member 55 attached to the first vertical frame 10a of the frame body 2. The seal member 55 can be sandwiched between the first vertical frame 10a and the door base end portion, which serves as the outer edge 3e of the door 3 in the closed state. In other words, the seal member 55 can seal between the door base end portion, which serves as the outer edge 3e of the door 3 in the closed state, and the first vertical frame 10a of the frame body 2.

[0049] As shown in FIG. 2, the second vertical frame 10b of this embodiment includes an aluminum second vertical frame body 10b1 with an endless portion 11b and a door edge covering portion 51 as a resin covering portion 50 connected to the second vertical frame body 10b1. As shown in FIG. 2, the second vertical frame body 10b1 is positioned adjacent to the door 3 in the closed state in the width direction B. In contrast, as shown in FIG. 2, the door edge covering portion 51 is positioned adjacent to the door tip portion, which serves as the outer edge 3e of the door 3 in the closed state, in the width direction A. The entrance structure 100 of this embodiment includes a rubber seal member 56 attached to the second vertical frame 10b of the frame body 2. The seal member 56 can be sandwiched between the second vertical frame 10b and the door tip portion, which serves as the outer edge 3e of the door 3 in the closed state. In other words, the seal member 56 can seal between the door tip portion, which serves as the outer edge 3e of the door 3 in the closed state, and the second vertical frame 10b of the frame body 2.

[0050] Furthermore, as shown in FIG. 3 , the upper horizontal frame 20a of this embodiment includes an aluminum upper horizontal frame body 20a1 with an endless portion 11c and an upper end covering portion 53 as a resin covering portion 50 connected to the upper horizontal frame body 20a1. The upper horizontal frame body 20a1 of this embodiment is configured with a hollow material that forms the endless portion 11c. As shown in FIG. 3 , the upper horizontal frame body 20a1 is positioned adjacent to the door 3 in the closed state above in the vertical direction C. In contrast, as shown in FIG. 3 , the upper end covering portion 53 is positioned adjacent to the upper end portion, which serves as the outer edge portion 3e of the door 3 in the closed state, in the projected width direction A. The doorway structure 100 of this embodiment includes a rubber seal member 57 attached to the upper horizontal frame 20a of the frame body 2. The seal member 57 can be sandwiched between the upper horizontal frame 20a and the upper end portion, which serves as the outer edge portion 3e of the door 3 in the closed state. In other words, the gap between the door tip portion, which is the outer edge portion 3e of the door 3 in the closed state, and the upper horizontal frame 20a of the frame body 2 can be sealed by the sealing member 57.

[0051] As shown in FIGS. 2 and 3 , the exterior wall 202 serving as the wall portion 1 includes a wall element (hereinafter, for convenience of explanation, referred to as a “low thermal conductivity wall element”) arranged on the opposite side of the cover portion 50 from the side where the door 3 is located in the closed state in the projected width direction A. The wall element is made of a material having a thermal conductivity equal to or lower than that of the material constituting the cover portion 50. The low thermal conductivity wall element in this embodiment is the interior frame material 205b. In other words, in the entrance structure 100, the outer edge portion 3e of the door 3, the resin cover portion 50, and the low thermal conductivity wall element made of a material having a thermal conductivity lower than that of the material constituting the cover portion 50 are arranged side by side in the projected width direction A. Specifically, the resin cover portion 50 in this embodiment is made of vinyl chloride, and the interior frame material 205b in this embodiment is made of wood. The thermal conductivity of wood is lower than that of vinyl chloride.

[0052] In this way, the outer edge 3e of the door 3, the resin covering portion 50, and the low thermal conductivity wall element are arranged side by side in the projected width direction A, so that one side of the outer edge 3e of the door 3 in the projected width direction A is covered by both the covering portion 50 and the low thermal conductivity wall element, thereby preventing the formation of a thermal bridge in the projected width direction A through the outer edge 3e of the door 3.

[0053] In this embodiment, the low thermal conductive wall element is the interior frame material 205b, but is not limited to this configuration. The low thermal conductive wall element may be an interior material 205 other than the interior frame material 205b, such as the interior wall material 205a. The low thermal conductive wall element may also be, for example, the heat insulating material 204.

[0054] Furthermore, as shown in Figures 2 and 3, it is preferable that the visible surface 50a of the covering portion 50 facing the entrance / exit 1a is formed as a flat surface. Specifically, in this embodiment, the visible surface 50a of the covering portion 50 is formed as a flat surface parallel to the projected width direction A. In other words, no steps are formed on the visible surface 50a of the covering portion 50. This reduces the surface area of ​​the visible surface 50a of the covering portion 50, thereby suppressing heat transfer through the visible surface 50a. In other words, it is possible to further suppress the formation of a thermal bridge in the projected width direction A through the outer edge portion 3e of the door 3. Note that in this embodiment, the visible surface 51a of the door tip covering portion 51, the visible surface 52a of the door base covering portion 52, and the visible surface 53a of the upper end covering portion 53 are each formed as a flat surface parallel to the projected width direction A.

[0055] As shown in FIG. 3 , the upper horizontal frame 20a of this embodiment is fixed to the structural body 210. Specifically, the upper horizontal frame 20a of this embodiment is fixed to the exterior wall 202, which serves as the wall portion 1 of the upper structure, which serves as the structural body 210. More specifically, the upper horizontal frame member 40a of the exterior wall 202 of this embodiment is disposed adjacent to the upper horizontal frame 20a and extends substantially parallel to the upper horizontal frame 20a. The upper horizontal frame 20a of this embodiment is fixed to the upper horizontal frame member 40a of the exterior wall 202. In this embodiment, the upper horizontal frame 20a and the upper horizontal frame member 40a are fixed by welding at the welded portion X1. However, the upper horizontal frame 20a and the upper horizontal frame member 40a may also be fixed by fastening members such as bolts or screws.

[0056] Note that the lower horizontal frame 20b is also fixed to the structural body 210, similar to the upper horizontal frame 20a shown in FIG. 3 . Specifically, the lower horizontal frame 20b in this embodiment is fixed to the exterior wall 202, which serves as the wall portion 1, of the upper structure, which serves as the structural body 210. More specifically, the lower horizontal frame member 40b of the exterior wall 202 in this embodiment is disposed adjacent to the lower horizontal frame 20b and extends substantially parallel to the lower horizontal frame 20b. The lower horizontal frame 20b in this embodiment is fixed to the lower horizontal frame member 40b. In this embodiment, the lower horizontal frame 20b and the lower horizontal frame member 40b are fixed by welding. However, the lower horizontal frame 20b and the lower horizontal frame member 40b may also be fixed by fastening members such as bolts or screws.

[0057] Furthermore, although the lower horizontal frame 20b in this embodiment is fixed to the lower horizontal frame member 40b of the wall 1 (the outer wall 202 in this embodiment) of the upper structure serving as the structural body 210, this configuration is not limited thereto. The lower horizontal frame 20b may be fixed, for example, to the floor of the upper structure serving as the structural body 210. The lower horizontal frame 20b may also be fixed, for example, to the foundation structure serving as the structural body 210. Hereinafter, for convenience of explanation, when there is no need to distinguish between the lower horizontal frame member 40b of the wall 1 of the upper structure, the floor of the upper structure, and the foundation structure to which the lower horizontal frame 20b may be fixed, they will simply be referred to as the "lower horizontal frame fixing portion."

[0058] In this way, in the entrance structure 100, the upper horizontal frame 20a and the lower horizontal frame 20b of the frame body 2 are fixed to the structural body 210.

[0059] In contrast, in the entrance structure 100 of this embodiment, the first vertical frame 10a and the second vertical frame 10b of the frame body 2 are not fixed to the structural skeleton 210. Specifically, in the entrance structure 100 of this embodiment, the first vertical frame 10a and the second vertical frame 10b of the frame body 2 are not fixed to the outer wall 202, which serves as the wall portion 1, in the upper structure, which serves as the structural skeleton 210. Therefore, even if, for example, inter-story displacement occurs in the building 200 during an earthquake and the wall portion 1 deforms, the first vertical frame 10a and the second vertical frame 10b can be prevented from deforming in accordance with the structural skeleton 210. In other words, damage to the first vertical frame 10a and the second vertical frame 10b can be prevented during an earthquake.

[0060] Specifically, as shown in FIG. 2, the first vertical frame member 30a of the exterior wall 202 serving as the wall portion 1 of this embodiment is disposed adjacent to the first vertical frame 10a and extends substantially parallel to the first vertical frame 10a. As shown in FIG. 1, the first vertical frame member 30a is directly attached to the upper horizontal frame member 40a and the lower horizontal frame member 40b. More specifically, as described above, the first vertical frame member 30a is fixed to the upper horizontal frame member 40a and the lower horizontal frame member 40b by fastening, welding, or the like. However, the first vertical frame 10a of this embodiment is not fixed to the first vertical frame member 30a. In other words, the first vertical frame 10a of this embodiment is not fixed to the first vertical frame member 30a by fastening members such as bolts or screws. Furthermore, the first vertical frame 10a of this embodiment is not fixed to the first vertical frame member 30a by welding. Furthermore, in this embodiment, the first vertical frame 10a is disposed at a distance from the first vertical frame member 30a. Therefore, even if inter-story displacement occurs in the building 200 and the first vertical frame member 30a deforms so as to tilt with respect to the vertical direction C, the first vertical frame 10a can be prevented from deforming excessively in response to the deformation of the first vertical frame member 30a. As a result, damage to the first vertical frame 10a can be prevented.

[0061] The same applies to the second vertical frame 10b and the second vertical frame member 30b. That is, as shown in FIG. 2, the second vertical frame member 30b of the exterior wall 202 serving as the wall portion 1 of this embodiment is disposed adjacent to the second vertical frame 10b and extends substantially parallel to the second vertical frame 10b. And, as shown in FIG. 1, the second vertical frame member 30b is directly attached to the upper horizontal frame member 40a and the lower horizontal frame member 40b. More specifically, as described above, the second vertical frame member 30b is fixed to the upper horizontal frame member 40a and the lower horizontal frame member 40b by fastening, welding, or the like. However, the second vertical frame 10b of this embodiment is not fixed to the second vertical frame member 30b. That is, the second vertical frame 10b of this embodiment is not fixed to the second vertical frame member 30b by fastening members such as bolts or screws. Furthermore, the second vertical frame 10b of this embodiment is not fixed to the second vertical frame member 30b by welding. Furthermore, in this embodiment, the second vertical frame 10b is disposed at a distance from the second vertical frame member 30b. Therefore, even if inter-story displacement occurs in the building 200 and the second vertical frame member 30b deforms so as to tilt with respect to the vertical direction C, the second vertical frame 10b can be prevented from deforming excessively in response to the deformation of the second vertical frame member 30b. As a result, damage to the second vertical frame 10b can be prevented.

[0062] As described above, in the entrance / exit structure 100, the upper horizontal frame 20a and lower horizontal frame 20b of the frame body 2 are fixed to the structural body 210, while the first vertical frame 10a and second vertical frame 10b of the frame body 2 are not fixed to the structural body 210.

[0063] As shown in Fig. 2, the exterior wall 202 serving as the wall portion 1 of this embodiment includes, in addition to the first vertical frame member 30a described above, an exterior wall panel serving as a first wall panel member 203a that is disposed adjacent to the first vertical frame 10a and directly attached to the upper horizontal frame member 40a and the lower horizontal frame member 40b, and to which the first vertical frame 10a is not fixed. In other words, the first vertical frame 10a of the frame body 2 of this embodiment is not fixed to either the first vertical frame member 30a or the first wall panel member 203a. As shown in Fig. 2, a sealant 207 is filled in the gap between the first vertical frame 10a of the frame body 2 of this embodiment and the first wall panel member 203a.

[0064] 2, the exterior wall 202 serving as the wall portion 1 of this embodiment includes, in addition to the second vertical frame member 30b described above, an exterior wall panel serving as a second wall panel member 203b that is disposed adjacent to the second vertical frame 10b and is directly attached to the upper horizontal frame member 40a and the lower horizontal frame member 40b, to which the second vertical frame 10b is not fixed. In other words, the second vertical frame 10b of the frame body 2 of this embodiment is not fixed to either the second vertical frame member 30b or the second wall panel member 203b. As shown in FIG. 2, a sealant 207 is filled in the gap between the second vertical frame 10b of the frame body 2 of this embodiment and the second wall panel member 203b.

[0065] In this embodiment, the first wall panel member 203a and the second wall panel member 203b are attached to the upper and lower beams of the horizontal frame member 40 so that they can rotate relative to the upper and lower beams when inter-story displacement occurs. In other words, the exterior wall 202 in this embodiment has a locking mechanism. Therefore, the gap distance between the first vertical frame 10a, which is filled with the sealant 207, and the first wall panel member 203a is adjusted so that the first vertical frame 10a of the frame body 2 and the first wall panel member 203a do not interfere with each other when the first panel member 203a rotates during an earthquake. The same applies to the gap distance between the second vertical frame 10b, which is filled with the sealant 207, and the second wall panel member 203b.

[0066] In this embodiment, both the first vertical frame member 30a and the first wall panel member 203a are disposed adjacent to the first vertical frame 10a, but this configuration is not limited thereto. For example, as shown in Fig. 4, if the upper horizontal frame 20a is fixed to an upper beam serving as an upper horizontal frame member 40a and the lower horizontal frame 20b is fixed to a lower beam serving as a lower horizontal frame member 40b, the first vertical frame member 30a may be omitted. In other words, the wall unit 1 may be configured not to include the first vertical frame member 30a attached to the upper horizontal frame member 40a and the lower horizontal frame member 40b adjacent to the first vertical frame 10a, but to include the first wall panel member 203a attached to the upper horizontal frame member 40a and the lower horizontal frame member 40b adjacent to the first vertical frame 10a. In this embodiment, the upper horizontal frame 20a is fixed to an upper beam as the upper horizontal frame member 40a, and the lower horizontal frame 20b is fixed to a lower beam as the lower horizontal frame member 40b. However, the configuration in which the first vertical frame member 30a can be omitted is not limited to this configuration. The first vertical frame member 30a can also be omitted when the upper horizontal frame 20a is fixed to an upper beam as the upper horizontal frame member 40a, and the lower horizontal frame 20b is fixed to a foundation structure or a floor.

[0067] In addition, in this embodiment, both the second vertical frame member 30b and the second wall panel member 203b are disposed adjacent to the second vertical frame 10b, but this configuration is not limited thereto. For example, as shown in Fig. 4, if the upper horizontal frame 20a is fixed to an upper beam serving as an upper horizontal frame member 40a and the lower horizontal frame 20b is fixed to a lower beam serving as a lower horizontal frame member 40b, the second vertical frame member 30b may be omitted. In other words, the wall 1 may be configured not to include the second vertical frame member 30b attached to the upper horizontal frame member 40a and the lower horizontal frame member 40b adjacent to the second vertical frame 10b, but to include the second wall panel member 203b attached to the upper horizontal frame member 40a and the lower horizontal frame member 40b adjacent to the second vertical frame 10b. In this embodiment, the upper horizontal frame 20a is fixed to an upper beam as the upper horizontal frame member 40a, and the lower horizontal frame 20b is fixed to a lower beam as the lower horizontal frame member 40b. However, the configuration in which the second vertical frame member 30b can be omitted is not limited to this configuration. The second vertical frame member 30b can also be omitted, for example, even when the upper horizontal frame 20a is fixed to an upper beam as the upper horizontal frame member 40a, and the lower horizontal frame 20b is fixed to a foundation structure or a floor portion.

[0068] However, from the viewpoint of reinforcing the area around the entrance 1a, it is preferable that the wall portion 1 includes a first vertical frame member 30a and a second vertical frame member 30b.

[0069] As described above, in the doorway structure 100, the first vertical frame 10a and the second vertical frame 10b of the frame body 2 are not fixed to the wall 1. Therefore, forces acting on the frame body 2 due to wind pressure on the door 3, forces acting on the frame body 2 when the door 3 is opened and closed, etc. are borne by the wall 1 via the upper horizontal frame member 40a and the lower horizontal frame member 40b that are fixed to the wall 1, but are not borne by the wall 1 via the first vertical frame 10a and the second vertical frame 10b that are not fixed to the wall 1. In other words, when the first vertical frame 10a and the second vertical frame 10b of the frame body 2 are not fixed to the wall 1, the first vertical frame 10a and the second vertical frame 10b are subjected to forces acting on the frame body 2 due to wind pressure on the door 3, forces acting on the frame body 2 when the door 3 is opened and closed, etc., compared to when the first vertical frame 10a and the second vertical frame 10b are fixed to the wall 1. Therefore, it is preferable that the first vertical frame 10a and the second vertical frame 10b have a high strength structure.

[0070] Therefore, the first vertical frame 10a and the second vertical frame 10b of this embodiment each have an endless portion that extends in the vertical direction C and defines a hollow portion inside when viewed in a cross section perpendicular to the vertical direction C (see FIG. 2). Specifically, the first vertical frame 10a of this embodiment has an endless portion 11a that defines a hollow portion 12a inside when viewed in a cross section perpendicular to the vertical direction C (see FIG. 2). Furthermore, the second vertical frame 10b of this embodiment has an endless portion 11b that defines a hollow portion 12b inside when viewed in a cross section perpendicular to the vertical direction C (see FIG. 2). In this way, by each of the first vertical frame 10a and the second vertical frame 10b having an endless portion, the first vertical frame 10a and the second vertical frame 10b can each be configured to be lightweight and high-strength.

[0071] Each of the first vertical frame 10a and the second vertical frame 10b may include, for example, a hollow material. Hollow material is, for example, an aluminum profile formed by aluminum extrusion. By including hollow material in the first vertical frame 10a and the second vertical frame 10b in this manner, lightweight, high-strength vertical frames can be easily formed. In the first vertical frame 10a of this embodiment, a door-end covering portion 52 serving as a resin covering portion 50 is integrally attached to the first vertical frame main body 10a1 made of hollow material. In addition, in the second vertical frame 10b of this embodiment, a door-end covering portion 51 serving as a resin covering portion 50 is integrally attached to the second vertical frame main body 10b1 made of hollow material.

[0072] Note that the first vertical frame 10a and the second vertical frame 10b may each be configured to include, for example, a plate-shaped frame material and a reinforcing material attached to the plate-shaped frame material. In other words, the strength of a plate-shaped frame material without an endless portion may be reinforced by attaching a reinforcing material. The first vertical frame 10a and the second vertical frame 10b, each including such a plate-shaped frame material and reinforcing material, may be configured such that the plate-shaped frame material itself does not have an endless portion, but forms an endless portion together with the reinforcing material. Furthermore, the first vertical frame 10a and the second vertical frame 10b, each including a plate-shaped frame material and reinforcing material, may be configured such that the plate-shaped frame material and reinforcing material do not form an endless portion, and the strength of the plate-shaped frame material is sufficiently reinforced by the reinforcing material. In other words, the first vertical frame 10a and the second vertical frame 10b may each be configured without an endless portion, as long as sufficient strength can be ensured.

[0073] The entrance structure and building according to the present invention are not limited to the specific configurations shown in the above-described embodiments, and various modifications, alterations, and combinations are possible without departing from the scope of the claims. In the above-described embodiments, the lower horizontal frame 20b is fixed to the lower horizontal frame member 40b of the wall 1 as a lower horizontal frame fixing portion, and the first vertical frame member 30a and the second vertical frame member 30b are directly attached to the lower horizontal frame member 40b of the exterior 1 as a lower horizontal frame fixing portion. In contrast, if the lower horizontal frame 20b is fixed to the floor as a lower horizontal frame fixing portion, for example, the first vertical frame member 30a and the second vertical frame member 30b do not need to be directly attached to the floor as a lower horizontal frame fixing portion. In this case, the first vertical frame member 30a and the second vertical frame member 30b may be attached directly to the lower horizontal frame member 40b of the wall 1, a foundation structure, etc., which is fixed in position relative to the floor as the lower horizontal frame fixing part, or may be attached indirectly to the floor as the lower horizontal frame fixing part via the lower horizontal frame member 40b of the wall 1, a foundation structure, etc. The same applies to the attachment of the first wall panel member 203a and the second wall panel member 203b.
