[0020] Hereinafter, embodiments of an exterior floor structure with a louver screen, a building, and a louver panel according to the present invention will be described with reference to the drawings. In each drawing, the same components are given the same reference numerals.

[0021] FIG. 1 is a plan view showing a building 200 as one embodiment of a building according to the present disclosure. The building 200 includes a building 210 and an exterior structure 220 associated with the building 210, which are arranged within a site 300. The exterior structure 220 includes an exterior structure floor section 3 that can be accessed through an entrance 211a provided in an exterior wall 211 on the first floor of the building 210. FIG. 2 is a diagram showing the vicinity of the exterior structure floor section 3 in FIG. 1, and is a schematic diagram of an exterior structure floor structure 100 with a louver screen as one embodiment of the exterior structure floor structure with a louver screen according to the present disclosure. FIG. 3 is a front view of the louver screen 5 in the exterior structure floor structure 100 with a louver screen. FIGS. 4 to 7 are diagrams showing the details of the exterior structure floor structure 100 with a louver screen. Specifically, FIG. 4 is a plan view showing the exterior structure floor section 3 and the louver screen 5 in the exterior structure floor structure 100 with a louver screen. However, the exterior floor material 12 of the exterior floor portion 3 is not shown in Fig. 4. Figs. 5 to 7 are diagrams showing the details of the mounting structure of the louver screen 5.

[0022] First, an overview of the building 210 will be described. The building 210 can be, for example, a two-story detached house having a steel-framed framework. Such a building 210 includes, for example, a foundation structure, such as a reinforced concrete slab supported on the ground G, and a superstructure having a framework made of framework members such as pillar members and beam members as structural materials and supported by the foundation structure. The framework members constituting the framework can be standardized members in advance, and are manufactured in a factory beforehand and then transported to a construction site and assembled. However, the building 210 may be a wooden house constructed by a so-called conventional construction method. The building 210 may also be a house made of reinforced concrete. Furthermore, the building 210 is not limited to being two-story, and may have three or more floors. Furthermore, the building 210 is not limited to being a detached house, and may be, for example, an apartment building, and its use is not particularly limited.

[0023] The upper structure of this embodiment comprises a frame consisting of a plurality of column members and a plurality of beam members installed between these column members, an exterior wall 211 arranged on the outer periphery of the frame, and a floor supported by the beam members of the frame.

[0024] The exterior wall 211 is a wall that separates the indoor and outdoor areas of the building 210. The outdoor surface of the exterior wall 211 may be composed of connected exterior wall panels as exterior materials. In addition, a heat insulating material and an interior material that form a heat insulating layer may be arranged on the indoor side of the exterior wall panel of the exterior wall.

[0025] The exterior wall panels may be, for example, panels made of autoclaved light weight concrete (hereinafter referred to as "ALC"). Metal or ceramic siding, extruded cement boards, wood panels, etc. By connecting these exterior wall panels to the periphery of the framework, the exterior skin layer of the exterior wall 211 can be formed.

[0026] As the heat insulating material, for example, a panel-shaped heat insulating material made of a foamed resin material such as phenol foam, polystyrene foam, urethane foam, etc., as well as a fiber-based heat insulating material such as rock wool can be used. By arranging this heat insulating material on the indoor side of the exterior wall panel along the inner surface of the exterior wall panel, a heat insulating layer can be formed in the exterior wall 211. As the interior material, for example, gypsum board can be used, and by connecting the interior material to the indoor side of the outer periphery of the frame, an inner skin layer can be formed.

[0027] The floor includes a floor slab material. The floor slab material is installed between beam members of the frame and is directly or indirectly supported by the beam members. For example, an ALC panel can be used as the floor slab material, but other materials such as folded plates, extruded cement boards, and wood panels may also be used. In addition to the floor slab material, the floor may include, for example, a ceiling interior material that forms the ceiling surface of the lower floor and is attached directly or indirectly to the floor slab material, and a floor interior material such as flooring that forms the floor surface of the upper floor and is laminated on the floor slab material.

[0028] The roof of the building 210 may be a flat roof. The roof floor slab material constituting the flat roof may be made of ALC panels, but is not limited to ALC panels. The roof floor slab material is waterproofed by being covered with a waterproof sheet made of polyvinyl chloride resin, for example. The roof of the building 210 is not limited to a flat roof, and may be a sloped roof using a roof exterior material such as slate.

[0029] Next, the exterior floor structure 100 with a louver screen of the exterior 220 will be described with reference to Fig. 1 to Fig. 7. As described above, the exterior floor structure 100 with a louver screen of this embodiment is provided with an exterior floor section 3 that can be accessed through an entrance 211a provided in an exterior wall 211 on the first floor of a building 210. A fitting 211b such as a bay window is provided in the entrance 211a.

[0030] More specifically, the exterior floor structure 100 with a louver screen comprises a foundation portion 2 fixed to the ground G, an exterior floor portion 3, a floor support portion 4, and a louver screen 5. The louver screen 5 in this embodiment is formed by connecting a plurality of louver panels 6 (four in this embodiment), but is not limited to this configuration.

[0031] The foundation portion 2 is placed on the ground G to support the exterior floor portion 3. The foundation portion 2 may be, for example, a concrete floor poured on the ground G. The concrete floor as the foundation portion 2 may be reinforced concrete including reinforcing bars.

[0032] The exterior floor section 3 is disposed at a distance above the foundation section 2 in the vertical direction A. The exterior floor section 3 is supported on the foundation section 2 via beam members 21 of the floor support section 4, which will be described later. The exterior floor section 3 of this embodiment includes a cross member 11 supported by the beam members 21 of the floor support section 4, which will be described later, and an exterior floor material 12 supported by this cross member 11.

[0033] More specifically, the cross member 11 of this embodiment includes a long beam member 11a that is directly supported by the beam member 21 of the floor support section 4 and extends horizontally, and a long joist member 11b that is supported by the beam member 11a and extends horizontally. The beam member 11a and the joist member 11b extend in directions perpendicular to each other in a plan view (see FIG. 4). The beam members 11a and the joist members 11b are arranged in parallel at predetermined intervals.

[0034] The exterior flooring 12 may be, for example, a strip-shaped deck material. The exterior flooring 12 of this embodiment is spanned across a plurality of joist members 11b arranged in parallel at a predetermined interval, and is supported by the plurality of joist members 11b. The exterior flooring 12 may be attached to the joist members 11b of the cross members 11 by fastening members such as screws.

[0035] The exterior floor section 3 is not particularly limited as long as it is arranged above the foundation section 2 in the vertical direction A at a distance via the floor support section 4. The exterior floor section 3 of this embodiment is configured to include a cross member 11 and an exterior floor material 12, but may have another configuration.

[0036] The floor support 4 stands on the foundation 2 and supports the exterior floor 3. Specifically, the floor support 4 of this embodiment includes a plurality of bundle members 21 to which the lower end of the foundation 2 in the vertical direction A is fixed and which extend upward in the vertical direction A from the lower end. The lower end of the bundle member 21 may be fixed to the foundation 2 using, for example, an anchor bolt protruding from the foundation 2. The beam member 11a of the exterior floor 3 of this embodiment described above is supported by being spanned across the plurality of bundle members 21. In this way, the exterior floor 3 is disposed at a position spaced above the foundation 2 in the vertical direction A by the floor support 4.

[0037] The floor support part 4 is not particularly limited as long as it is erected from the foundation part 2 and configured to support the exterior floor part 3. The floor support part 4 in this embodiment is configured to include a beam member 21, but may have another configuration.

[0038] The louver screen 5 is arranged to cover the outer edge 3a of the exterior floor 3, and extends above and below the exterior floor 3 in the vertical direction A. The height of the louver screen 5 from the ground G may be, for example, 2000 to 2500 mm. The height of the louver screen 5 from the exterior floor 3 may be, for example, 1500 to 2000 mm. The louver screen 5 extends in the vertical direction A and includes a plurality of louver vertical members 31 that are connected at predetermined intervals in the screen width direction B (hereinafter simply referred to as "width direction B").

[0039] As shown in FIG. 1, the louver screen 5 of this embodiment includes a front screen portion 51 arranged in a position facing the exterior wall 211 of the building 210 across the exterior floor portion 3 in a plan view, and a side screen portion 52 arranged on the side not facing the exterior wall 211 of the building 210 across the exterior floor portion 3 in a plan view. The front screen portion 51 and the side screen portion 52 form a corner portion 53. However, the arrangement of the louver screen 5 is not limited to this configuration. The louver screen 5 may be appropriately arranged depending on the shape of the outer edge 3a of the exterior floor portion 3, the arrangement position of the exterior floor portion 3 within the site 300, the relationship with the neighboring land, and the like. Therefore, the louver screen 5 may be configured to include only the front screen portion 51, for example.

[0040] As shown in Figs. 3 to 7, the multiple louver vertical members 31 of the louver screen 5 include a louver vertical member 31a that is supported by the exterior floor section 3 or the floor support section 4 at a first position P1 and is supported by the floor support section 4 or the foundation section 2 at a second position P2 that is lower in the vertical direction A than the first position P1. Also, as shown in Figs. 3 and 4, the multiple louver vertical members 31 of the louver screen 5 of this embodiment include a louver vertical member 31b that is attached to the louver vertical member 31a and supported by at least one of the foundation section 2, the exterior floor section 3, and the floor support section 4 only via the louver vertical member 31a. Hereinafter, for convenience of explanation, in order to distinguish between the louver vertical member 31a and the louver vertical member 31b among the louver vertical members 31 of the louver screen 5, the louver vertical member 31a will be described as a "main louver vertical member 31a" and the louver vertical member 31b will be described as a "sub louver vertical member 31b". Furthermore, when there is no need to distinguish between all of the louver vertical members 31, including the main louver vertical members 31a and the sub louver vertical members 31b, they will simply be referred to as "louver vertical members 31".

[0041] In this way, the multiple louver vertical members 31 of the louver screen 5 of this embodiment include main louver vertical members 31a that are supported by at least one of the foundation portion 2, exterior floor portion 3 and floor support portion 4 located on the inside covered by the louver screen 5 without being interposed between them and another louver vertical member 31, and sub louver vertical members 31b that are supported by at least one of the foundation portion 2, exterior floor portion 3 and floor support portion 4 only via the main louver vertical member 31a.

[0042] As described above, the main louver vertical member 31a is supported by the exterior floor portion 3 or the floor support portion 4 at the first position P1. Specifically, the main louver vertical member 31a in this embodiment is supported by the exterior floor portion 3 at the first position P1. More specifically, the main louver vertical member 31a in this embodiment is supported by the horizontal member 11 of the exterior floor portion 3 at the first position P1.

[0043] As shown in FIG. 4, the front screen portion 51 of the louver screen 5 of this embodiment extends substantially parallel to the beam member 11a of the cross member 11 in a plan view. Therefore, as shown in FIGS. 4 to 6, the main louver vertical members 31a of the front screen portion 51 of the louver screen 5 are attached to the beam member 11a via the mounting brackets 61 attached to the beam member 11a, and are supported by the beam member 11a. The main louver vertical members 31a and the mounting brackets 61 may be attached by fastening them with fastening members 81 such as bolts and nuts. The mounting brackets 61 and the beam member 11a may also be attached by fastening them with fastening members 82 such as screws. As shown in FIGS. 5 and 6, in this embodiment, two L-shaped mounting hardware 61 fastened with fastening members such as bolts and nuts are provided, but the number and shape of the mounting hardware 61 may be set appropriately.

[0044] In contrast, as shown in Fig. 4, the side screen portion 52 of the louver screen 5 of this embodiment extends substantially parallel to the joist member 11b of the cross member 11 in a plan view. Therefore, as shown in Fig. 4, the main louver vertical member 31a of the side screen portion 52 of the louver screen 5 is attached to the joist member 11b via a mounting bracket 62 attached to the joist member 11b, and is supported by the joist member 11b. The main louver vertical member 31a and the mounting bracket 62 may be attached by being fastened with a fastening member 81 such as a bolt or nut. The mounting bracket 62 and the joist member 11b may also be attached by being fastened with a fastening member such as a bolt, nut, or screw.

[0045] As described above, the main louver vertical members 31a are supported by the floor support portion 4 or the foundation portion 2 at the second position P2. Specifically, the main louver vertical members 31a in this embodiment are supported by the foundation portion 2 at the second position P2.

[0046] More specifically, in a plan view, the foundation part 2 of this embodiment is not disposed at a position overlapping with the main louver vertical member 31a. That is, as shown in FIG. 5 and FIG. 7(a), the foundation part 2 of this embodiment is disposed directly below the exterior floor part 3 in the vertical direction A, but is not disposed directly below the main louver vertical member 31a in the vertical direction A. The main louver vertical member 31a is supported on the foundation part 2 via the mounting member 71 at the second position P2. The mounting member 71 is fixed to the foundation part 2. The mounting member 71 may be fixed to the foundation part 2, for example, by using an anchor bolt 86 protruding from the foundation part 2. The mounting member 71 of this embodiment is fixed to the foundation part 2 in a state where a part of the mounting member 71 protrudes from the outer edge 2a of the foundation part 2. The end face 71h of the part of the mounting member 71 protruding from the outer edge 2a of the foundation part 2 abuts against the inner surface of the main louver vertical member 31a on the exterior floor part 3 side (the inner side in the thickness direction of the louver screen 5). In this state, as shown in Fig. 7(a), the main louver vertical members 31a of this embodiment are attached to the foundation part 2 via mounting members 71 fixed to the foundation part 2, and are thereby supported by the foundation part 2. As shown in Figs. 5, 7(a) and 7(b), the main louver vertical members 31a and the mounting members 71 may be attached by being fastened together with fastening members 85 such as bolts and nuts.

[0047] As shown in FIG. 7(b), the mounting member 71 of this embodiment has a hat-shaped cross section. Specifically, the mounting member 71 of this embodiment includes a top plate portion 71a, a first side plate portion 71b and a second side plate portion 71c that hang down from the opposing outer edges of the top plate portion 71a, a first flange portion 71d that extends from the first side plate portion 71b, and a second flange portion 71e that extends from the second side plate portion 71c. The mounting member 71 of this embodiment also includes a first end plate portion 71f and a second single plate portion 71g that close both ends of the groove space formed by the top plate portion 71a, the first side plate portion 71b, and the second side plate portion 71c. The end surface 71h described above is the outer surface of the first end plate portion 71f.

[0048] The mounting member 71 of this embodiment is fixed to the foundation part 2 by fastening the first flange part 71d and the second flange part 71e using anchor bolts 86 protruding from the foundation part 2. Also, the main louver vertical member 31a of this embodiment is fastened to the mounting member 71 using bolts as fastening members 85 that penetrate the main louver vertical member 31a and are inserted into the first end plate part 71f and the second veneer part 71g located at both ends of the groove space of the mounting member 71. As shown in FIG. 7(a), the lower end of the main louver vertical member 31a is not supported by the ground G and is separated from the ground G by a gap.

[0049] In this manner, the main louver vertical member 31a in this embodiment is supported by the exterior floor portion 3 at the first position P1 and by the foundation portion 2 at the second position P2, but is not limited to this configuration. The main louver vertical member 31a may be supported by the floor support portion 4 at an upper side in the vertical direction A and by the foundation portion 2 at a lower side in the vertical direction A, for example. The main louver vertical member 31a may also be supported by the floor support portion 4 at two different points in the vertical direction A, for example.

[0050] In this way, the louver screen 5 of the exterior floor structure with a louver screen 100 is supported by the exterior floor part 3 or the floor support part 4 at the first position P1, and is provided with the main louver vertical members 31a that are supported by the floor support part 4 or the foundation part 2 at the second position P2 that is lower in the vertical direction A than the first position P1. By providing the louver screen 5 with such main louver vertical members 31a, it is not necessary to provide a foundation structure solely for firmly fixing the louver vertical members 31 of the louver screen 5 to the ground G. Therefore, the louver screen 5 can be installed firmly and efficiently.

[0051] In particular, it is preferable that the main louver vertical members 31a are supported by the exterior floor 3 at the first position P1 and by the foundation 2 at the second position P2, as in this embodiment. If the main louver vertical members 31a are supported by the exterior floor 3 at the first position P1, the support position of the main louver vertical members 31a in the vertical direction A can be made higher than in a configuration in which the main louver vertical members 31a are supported by the floor support 4 at the first position P1, and therefore the vertical posture of the main louver vertical members 31a is more likely to be stable. In addition, if the main louver vertical members 31a are supported by the foundation 2 at the second position P2, the foundation 2 for supporting the exterior floor 3 can also be used to support the main louver vertical members 31a.

[0052] The louver screen 5 of this embodiment includes sub-louver vertical members 31b in addition to the main louver vertical members 31a, but is not limited to this configuration. That is, all of the multiple louver vertical members 31 included in the louver screen 5 may be main louver vertical members 31a. In addition, when the louver screen 5 includes the main louver vertical members 31a and the sub louver vertical members 31b, the ratio of the numbers of the main louver vertical members 31a and the sub louver vertical members 31b is not particularly limited.

[0053] Furthermore, the louver screen 5 of this embodiment is formed by connecting a plurality of louver panels 6 including the main louver vertical member 31a and the sub louver vertical member 31b. More specifically, the front screen portion 51 of the louver screen 5 of this embodiment is formed by connecting three louver panels 6a to 6c in the width direction B. Furthermore, the side screen portion 52 of the louver screen 5 of this embodiment is formed by one louver panel 6d. The four louver panels 6a to 6d of this embodiment have substantially the same configuration. As shown in FIG. 4, the length of the strip-shaped plate material 32 of the two louver panels 6c and 6d forming the corner portion 53 of the louver screen 5 is adjusted so that the strip-shaped plate materials 32 do not interfere with each other. Except for the length of the strip-shaped plate material 32, the four louver panels 6a to 6d of this embodiment have the same shape. Hereinafter, when the four louver panels 6a to 6d are not particularly distinguished from each other, they will be simply referred to as "louver panels 6".

[0054] FIG. 8 is a front view of one louver panel 6. As shown in FIG. 8, the louver panel 6 of this embodiment includes twelve louver vertical members 31 spaced apart from each other in the width direction B. The twelve louver vertical members 31 are composed of two main louver vertical members 31a and ten sub louver vertical members 31b. The two main louver vertical members 31a are not located at both ends in the width direction B. It is preferable that the separation distance between the two main louver vertical members 31a in the width direction B is set to be approximately equal to the separation distance between the main louver vertical member 31a of one louver panel 6 and the main louver vertical member 31a of the other louver panel 6 when the two louver panels 6 are linearly connected in a plan view.

[0055] Moreover, the louver panel 6 of this embodiment further includes a belt-shaped plate material 32. The belt-shaped plate material 32 is arranged across the inner surface of each of the multiple louver vertical members 31 that faces the exterior floor part 3 (the inner side in the thickness direction of the louver screen 5 and the panel thickness direction C). More specifically, the belt-shaped plate material 32 of this embodiment is arranged across the inner surface of each of the main louver vertical members 31a and the sub louver vertical members 31b that faces the exterior floor part 3.

[0056] Furthermore, the louver panel 6 of this embodiment includes a fastening member 33 that extends through at least one of the louver vertical members 31 and the band-shaped plate member 32 and can be attached to the exterior floor portion 3. That is, the louver panel 6 of this embodiment can be attached to the exterior floor portion 3 by using the fastening member 33 that penetrates the louver vertical members 31 and the band-shaped plate member 32 in the panel thickness direction C (the same direction as the thickness direction of the louver screen 5). In other words, the fastening member 33 is also used as the fastening member 81 that penetrates the main louver vertical members 31a and the band-shaped plate member 32 in the exterior floor structure with louver screen 100 (see FIG. 4, etc.). The fastening member 33 is fastened to the mounting brackets 61, 62 attached to the horizontal members 11 of the exterior floor portion 3. In this manner, the louver panel 6 of this embodiment is supported on the exterior floor portion 3 by fastening the fastening members 33 that pass through the main louver vertical members 31a and the band-shaped plate members 32 to the mounting brackets 61, 62.

[0057] Furthermore, the louver panel 6 of this embodiment includes a through shaft member 34 that penetrates all the louver vertical members 31, including the main louver vertical members 31a and the sub louver vertical members 31b, in the width direction B. As shown in Fig. 8, the louver panel 6 of this embodiment includes four through shaft members 34. The four through shaft members 34 are disposed at four different positions in the vertical direction A. Also, as shown in Fig. 8, the through shaft member 34 includes a protruding portion 34a that protrudes outward in the width direction B from two louver vertical members 31 (sub louver vertical members 31b in this embodiment) located at both ends of the louver panel 6 in the width direction B.

[0058] Fig. 9 is an enlarged view of a portion of adjacent ends in the width direction B of two louver panels 6 that are linearly connected in a plan view (see Fig. 1) of the louver screen 5. Fig. 9 shows, as an example, the ends of the two louver panels 6a, 6b that form the front screen portion 51, but the ends of the two louver panels 6b, 6c are similar.

[0059] As shown in FIG. 9, the louver screen 5 of this embodiment includes a joint member 7 that is disposed between two louver panels 6a and 6b and is arranged so as to be coaxial with the through shaft members 34 of the two louver panels 6a and 6b. By providing such a joint member 7, the through shaft members 34 of the two louver panels 6a and 6b appear to be connected, so that the sense of unity between the two louver panels 6a and 6b can be enhanced, and the design of the louver screen 5 can be improved. The joint member 7 of this embodiment is a cylindrical member. The protruding portion 34a of the through shaft member 34 of one louver panel 6a is inserted into one end of the cylindrical member serving as the joint member 7. The protruding portion 34a of the through shaft member 34 of the other louver panel 6b is inserted into the other end of the cylindrical member serving as the joint member 7.

[0060] FIG. 10 is an enlarged plan view of a protruding corner portion 53 formed by two louver panels 6c and 6d of the louver screen 5. As shown in FIG. 10, the protruding corner portion 53 is formed by adjoining an inner side surface 31c1 of an end louver vertical member 31c (also a sub-louver vertical member 31b in this embodiment) located at an end of one of the two louver panels 6c and 6d, and a side surface 31c2 of an end louver vertical member 31c (also a sub-louver vertical member 31b in this embodiment) located at an end of the other of the two louver panels 6c and 6d. That is, the protruding corner portion 53 of the louver screen 5 of this embodiment is formed by only butting the end louver vertical members 31c of the two louver panels 6c and 6d together. Therefore, a dedicated panel or the like for forming the protruding corner portion 53 is not required. 10, the protrusions 34a of the louver panel 6d are disposed so as to fit between the louver vertical members 31 of the louver panel 6c. In other words, the protrusions 34a do not impede the formation of the projected corner portion 53. Furthermore, in terms of the appearance of the louver screen 5, the protrusions 34a are not easily noticeable, and the design of the louver screen 5 can be improved.

[0061] The exterior floor structure with a louver screen, the building, and the louver panel according to the present invention are not limited to the specific configurations shown in the above-described embodiments, and various modifications, variations, and combinations are possible without departing from the scope of the claims.

[0062] The louver screen 5 shown in the embodiment described above is formed by connecting four louver panels 6a to 6d of approximately the same width, but the number of louver panels 6 arranged, the width of each louver panel 6, the number of main louver vertical members 31a, the number of sub louver vertical members 31b, etc. may be set appropriately.
