[Figure 2] Figure 1 shows a schematic cross-sectional view of the portion of the exterior wall along line AA. [Figure 3] Figure 1 shows a schematic cross-sectional view of the portion of the exterior wall along the BB line. [Figure 4] This is an enlarged cross-sectional view of area C shown in Figure 3. [Figure 5] This is an explanatory diagram showing the direction in which the inner module unit is attached to and detached from the outer frame. [Modes for carrying out the invention]

[0014] The following describes in detail, with reference to the drawings, a frame unit opening system according to one embodiment of the present invention and a building equipped therewith.

[0015] The building 1 shown in Figure 1, according to one embodiment of the present invention, is a reinforced concrete building such as an office building. The frame unit opening system 10 according to one embodiment of the present invention is installed on the outer wall 2 of the building 1.

[0016] In this embodiment, multiple frame unit opening systems 10 are provided on the outer wall 2 in a vertical and horizontal direction. Figure 1 shows some of the frame unit opening systems 10 provided on the outer wall 2.

[0017] Furthermore, it is sufficient that at least one frame unit opening system 10 is provided on the outer wall 2 of the building 1. In addition, if multiple frame unit opening systems 10 are provided on the outer wall 2 of the building 1, the arrangement of these frame unit opening systems 10 is not limited to the arrangement shown in Figure 1 and can be changed in various ways.

[0018] The frame unit opening system 10 comprises an outer frame 20 and an inner module unit 30. In Figure 1, for convenience, only some of the outer frame 20 and inner module unit 30 are labeled with reference numerals.

[0019] The outer frame body 20 has an annular form with an inner opening, and the opening is supported by the building structure 3 of the building 1 in a posture penetrating the outer wall 2 of the building 1 in the inside-outside direction (the direction perpendicular to the outer wall 2). In the present embodiment, in the front view shown in FIG. 1, the outer frame body 20 has a rectangular shape including a pair of vertical frame portions 20a extending in the vertical direction and parallel to each other, and a pair of horizontal frame portions 20b extending in the horizontal direction and parallel to each other. Further, in the present embodiment, a plurality of outer frame bodies 20 corresponding to the plurality of frame unit opening systems 10 are integrally connected to each other and are configured in a grid shape as a whole.

[0020] Note that the outer frame body 20 may be configured to be supported by the building structure 3 by being directly fixed to the building structure 3 of the building 1, or may be configured to be supported by the building structure 3 of the building 1 via another member such as a steel frame.

[0021] The inner module unit 30 includes an inner frame body 31 and a functional portion 32 attached inside the inner frame body 31.

[0022] As shown in FIGS. 1, 2, and 3, the inner module unit 30 is detachably fitted inside the outer frame body 20. In the present embodiment, in each of the plurality of frame unit opening systems 10, two inner module units 30 are vertically arranged and fitted inside one outer frame body 20.

[0023] The inner frames 31 of the two inner module units 30 are each annular in shape with an opening on the inside, and in the front view shown in Figure 1, they have a rectangular shape comprising a pair of parallel vertical frame sections 31a extending in the vertical direction and a pair of parallel horizontal frame sections 31b extending in the horizontal direction. The horizontal width of the outer peripheral surface 31d of each inner frame 31 corresponds to the horizontal width of the inner peripheral surface 20c of the outer frame 20. On the other hand, the vertical height dimension of the outer peripheral surface 31d of each inner frame 31 is smaller than the vertical height dimension of the inner peripheral surface 20c of the outer frame 20. In other words, the vertical dimension obtained by adding the vertical height dimensions of the two inner frames 31 fitted inside one outer frame 20 corresponds to the vertical height dimension of the inner peripheral surface 20c of the outer frame 20. In this embodiment, of the two inner module units 30 fitted inside one outer frame 20, the vertical height dimension of the upper inner module unit 30 fitted inside is half the vertical height dimension of the lower inner module unit 30 fitted inside.

[0024] The functional part 32, which is installed inside the inner frame 31, is, for example, a glass plate, a louver, a solar panel, or an exterior wall panel. However, the functional part 32 is not limited to the glass plate, louver, solar panel, or exterior wall panel mentioned above.

[0025] In this embodiment, in one frame unit opening system 10 (the frame unit opening system 10 that is in the vertical center and second from the left in Figure 1), the functional part 32 of the upper inner module unit 30 fitted inside the outer frame 20 is a louver 32a, and the functional part 32 of the lower inner module unit 30 fitted inside the outer frame 20 is a glass plate 32b. Also in this embodiment, in another frame unit opening system 10 (the frame unit opening system 10 that is in the vertical center and second from the right in Figure 1), the functional part 32 of the upper inner module unit 30 fitted inside the outer frame 20 is a solar panel 32c, and the functional part 32 of the lower inner module unit 30 fitted inside the outer frame 20 is an exterior wall panel 32d. Similarly, the frame unit opening systems 10 with the two patterns described above are arranged alternately in the horizontal direction. Note that the combination of types of multiple functional parts 32 in each inner module unit 30 is not limited to the above and can be changed in various ways.

[0026] As shown in Figure 2, if the functional unit 32 is a louver 32a, the configuration may be such that the duct 33 is attached to the inner frame 31 on the indoor side of the louver 32a.

[0027] Furthermore, as shown in Figure 3, if the functional unit 32 is made of plate glass 32b, a configuration in which two layers of plate glass 32b are attached to the inner frame 31 is also possible. Alternatively, if the functional unit 32 is made of plate glass 32b, a configuration in which a blind 34 is attached to the outer frame 20 on the indoor side of the plate glass 32b is also possible.

[0028] If the functional unit 32 is a solar panel 32c, a plate material having a predetermined strength may be attached to the inside of the inner frame 31 together with the solar panel 32c.

[0029] When the functional unit 32 is made of an exterior wall panel 32d, various materials can be used for the exterior wall panel 32d. Alternatively, the exterior wall 2 may be configured as a curtain wall by providing multiple interior module units 30, each of which is an exterior wall panel 32d.

[0030] As shown in Figure 4, in order to detachably fix the inner module unit 30, the outer frame 20 is provided with a locking portion 21 and a circumferential groove 22 on its inner circumferential surface 20c.

[0031] The locking portion 21 protrudes from the inner circumferential surface 20c of the outer frame 20 and locks one end of the inner frame 31 of the inner module unit 30 fitted into the outer frame 20 (one end facing in the inward / outward direction of the building 1) in the inward / outward direction of the building 1. In this embodiment, the locking portion 21 is provided on the exterior side of the building 1 than the inner frame 31 and locks one end of the inner frame 31 that faces outward of the building 1.

[0032] In this embodiment, the locking portion 21 is in the form of a slot frame. More specifically, the locking portion 21 has an L-shaped cross-section, comprising a first wall portion 21a that protrudes perpendicularly from the inner circumferential surface 20c of the outer frame body 20, and a second wall portion 21b that is integrally connected to the tip of the first wall portion 21a and arranged parallel to the inner circumferential surface 20c. The locking portion 21 opens toward the interior side of the building 1 and is provided with a uniform cross-sectional shape around the entire circumference of the inner circumferential surface 20c of the outer frame body 20.

[0033] The circumferential groove 22 is positioned on the interior side of the building 1 with a gap between it and the locking portion 21. The distance between the locking portion 21 and the circumferential groove 22 in the inward-outward direction of the building 1 is approximately the same as the thickness dimension of the inner frame 31 of the inner module unit 30 in the inward-outward direction of the building 1.

[0034] In this embodiment, the circumferential groove 22 is a rectangular groove with a pair of side walls 22a and a bottom wall 22b, and opens to the inner circumferential surface 20c of the outer frame 20. The circumferential groove 22 is provided with a uniform cross-sectional shape over the entire circumference of the inner circumferential surface 20c of the outer frame 20.

[0035] An insertion projection 31c, shaped to correspond to the locking portion 21 in the form of a slot frame, is integrally provided on one end face of the inner frame 31 of the inner module unit 30. The insertion projection 31c is plate-shaped and flush with the outer peripheral surface 31d of the inner frame 31, and is inserted through the opening of the locking portion 21 and positioned between the inner peripheral surface 20c and the second wall portion 21b. As shown in Figure 5, the inner module unit 30 is positioned inside the outer frame 20 when the inner frame 31 is inserted from the indoor side into the outer frame 20, and the insertion projection 31c abuts against the first wall portion 21a of the locking portion 21, thereby locking to the locking portion 21. The insertion projection 31c is provided along the vertical frame portion 31a and the horizontal frame portion 31b of the inner frame 31, but not at the boundary between the vertical frame portion 31a and the horizontal frame portion 31b.

[0036] As described above, by inserting and locking the insertion projection 31c provided on the inner frame 31 into the locking portion 21 which is in the shape of a slot frame, the waterproofness between the outer frame 20 and the inner frame 31 can be improved. In this case, as shown in Figure 4, a water-stopping seal material 35 made of synthetic rubber such as chloroprene rubber may be attached between the insertion projection 31c and the side facing the second wall portion 21b. This further improves the waterproofness between the outer frame 20 and the inner frame 31.

[0037] A synthetic rubber sheet material 36 may be placed between the insertion projection 31c and the first wall portion 21a, sandwiched between the insertion projection 31c and the first wall portion 21a. Alternatively, a fixing rubber 37 may be placed between the inner circumferential surface 20c of the outer frame 20 and the outer circumferential surface 31d of the inner frame 31.

[0038] A trim member 40 is fitted into the circumferential groove 22. As shown in Figure 1, the trim member 40 has an annular shape that extends along the inner circumferential surface 20c of the outer frame 20. As shown in Figure 4, in this embodiment, the trim member 40 has a rectangular cross-section and is detachably fixed to the outer frame 20 by a screw member 41, with a part of it positioned inside the circumferential groove 22 and the other part protruding from the circumferential groove 22. The trim member 40 is supported by the outer frame 20 in the portion positioned inside the circumferential groove 22, and the portion protruding from the circumferential groove 22 is fixed by sandwiching the inner frame 31 between it and the locking portion 21.

[0039] A rubber sheet 38 may be placed between the pair of side walls 22a of the circumferential groove 22 and the trim member 40. In this case, the rubber sheet 38 placed on the exterior side relative to the trim member 40 may extend across the entire side surface of the trim member 40, with a portion of it placed between the trim member 40 and the inner frame 31. This further enhances the waterproofing between the outer frame 20 and the inner frame 31.

[0040] As shown in Figure 4, in this embodiment, the inner frame 31 has a pair of side walls 31e and an outer peripheral wall 31f, and its cross-sectional shape is U-shaped, opening inward. When the functional part 32 is a pair of glass plates 32b, the pair of glass plates 32b are placed side by side with a spacer 50 in between and inserted into the inside of the U-shape of the inner frame 31. In addition, a support rubber 51 is placed between each glass plate 32b and the side wall 31e of the inner frame 31, and a rubber body 52 is placed on the inner surface of the outer peripheral wall 31f that the pair of glass plates 32b abut against.

[0041] An opening attachment 53 may be installed between one side wall 31e of the inner frame 31 and the support rubber 51 and rubber body 52. ​​By using multiple types of opening attachments 53 with different widths, multiple types of functional parts 32 with different widths can be attached to the inside of one type of inner frame 31 of the same shape.

[0042] Furthermore, the shape of the inner frame 31 can be changed in various ways, not limited to the above, as long as it is a shape that allows the functional unit 32 to be attached to the inside.

[0043] In the building 1 or frame unit opening system 10 according to the above embodiment, if the outer frame 20 is pre-supported by fixing it to the building frame 3 of the building 1, the inner module unit 30, which has a functional part 32 attached to the inside of the inner frame 31, can be fitted into the inside of the outer frame 20, and the trim member 40 can be attached to the circumferential groove 22 provided in the outer frame 20, making it easy to install the inner module unit 30 having various functional parts 32 on the outer wall 2 of the building 1. Furthermore, in the case of renovation of the building 1, when it is necessary to install an inner module unit 30 having a different functional part 32 on the outer wall 2, or to replace the inner module unit 30, the inner module unit 30 can be easily removed from the outer frame 20 by removing the trim member 40 from the circumferential groove 22 without removing the outer frame 20 from the outer wall 2. This makes it easy to replace the inner module unit 30 on the outer wall 2 with an inner module unit 30 having a different functional part 32, or to replace it with a new inner module unit 30.

[0044] Thus, according to the building 1 or frame unit opening system 10 of this embodiment having the above configuration, various inner module units 30 having different functions depending on the function required of the exterior wall 2 can be easily installed on the exterior wall 2 with a simpler method and less effort than in the conventional method. Therefore, it is possible to easily respond to improvements in the functionality of the building 1 and changes in functions according to the user's requests.

[0045] Furthermore, in the building 1 or frame unit opening system 10 according to this embodiment, the locking portion 21 of the outer frame 20 is provided on the exterior side of the building 1 than the inner frame 31, so that the inner module unit 30 can be attached to and detached from the outer frame 20 on the interior side. This makes it possible to carry in and install the inner module unit 30 inside the building 1 with a floor, without using heavy machinery such as cranes or constructing scaffolding on the outside of the exterior wall 2, thereby making it possible to easily carry out installation and replacement work on the inner module unit 30.

[0046] Furthermore, in the building 1 or frame unit opening system 10 according to this embodiment, a plurality of inner module units 30 are fitted inside a single outer frame 20, making it even easier to install inner module units 30 having various functions according to the functions required of the outer wall 2 on the outer wall 2.

[0047] The present invention is not limited to the embodiments described above, and it goes without saying that various modifications are possible without departing from the spirit of the invention.

[0048] For example, in the above embodiment, the outer frame 20 is rectangular in shape when viewed from the front as shown in Figure 1, but its shape can be changed in various ways as long as the inner module unit 30 can be fitted inside.

[0049] Furthermore, in the above embodiment, two inner module units 30 are fitted inside one outer frame 20, but as long as at least one inner module unit 30 is fitted inside one outer frame 20, the number of inner module units 30 fitted inside one outer frame 20 can be varied.

[0050] Furthermore, while the above embodiment exemplifies a louver 32a, a glass plate 32b, a solar panel 32c, and an exterior wall panel 32d as functional units 32, the embodiment is not limited to these.

[0051] Furthermore, in the above embodiment, the locking portion 21 is provided on the exterior side of the building 1 rather than the inner frame 31, allowing the inner module unit 30 to be attached and detached from the interior side. However, the configuration is not limited to this, and the locking portion 21 may be provided on the interior side of the building 1 rather than the inner frame 31, allowing the inner module unit 30 to be attached and detached from the exterior side. In such a configuration as well, the inner module unit 30 can be easily removed from the outer frame 20 by removing the trim member 40 from the periphery groove 22, without performing any work to remove the outer frame 20 from the exterior wall 2 or the building structure 3, or any work on finishing materials. This makes it easy to replace the inner module unit 30 of the exterior wall 2 with an inner module unit 30 having other functional parts 32, or to replace it with a new inner module unit 30.
