Description

  The present invention relates to a building having a storage space and a building having a structure suitable for providing the storage space.

  In a building such as a house, a storage space such as a close-in, a top bag, a storage door, etc. is generally provided to store articles. In addition to these traditional storage spaces, in recent years, an intermediate floor lower than the upper and lower floors is formed between the upper and lower floors, and the intermediate floor is used as a storage space. Buildings have been put into practical use (for example, see Patent Documents 1 and 2).

  However, in the general two-story building 110 shown in FIG. 10A, the height of the entire building is determined by the floor height H1 of the first floor portion 111 and the floor height H2 of the second floor portion 112 including the roof portion. On the other hand, in the other building 120 having the intermediate floor portion 121 shown in FIG. 10B, the entire building is higher than the general building 110 by the height H3 of the intermediate floor portion 121.

  Then, in the latter building 120, since the building 120 becomes higher by the amount corresponding to the intermediate floor portion 121, restrictions due to the oblique line restriction such as the north side oblique line and the road oblique line in the Building Standard Law become large, and the intermediate floor portion 121 is provided. Therefore, the cost is significantly increased as compared with the building 110 that does not have it.

Furthermore, in the building 120 having such an intermediate floor portion 121, it is necessary to design the structure so that the number of floors is increased by the amount of the intermediate floor portion 121. The structural design is complicated as compared with a general two-story building 110.

  It is an object of the present invention to provide a building capable of constructing a large storage type storage space having a vertical position relative to a living room or the like without increasing the height of the building and without causing a significant cost increase. One of them.

  Another object of the present invention is to provide a building having such a structure that can realize such a storage space without significant changes to the structure of an existing building.

  In order to solve the above-described problems, in the first invention, a storage room is provided below the lower surface of the boundary between adjacent upper and lower floors, and a living room or garage is provided between the lower surface of the storage room and the lower floor surface. Is provided. In this case, a floor surface of a living room or a garage formed between the lower surface of the storage room and the floor surface of the lower floor is formed lower than the floor surface of another living room formed on the lower surface of the boundary portion. Is preferred.

  According to the first invention, without providing an intermediate floor between the upper and lower floors, the lower floor is provided with a storage chamber below the lower surface of the boundary between the upper and lower floors, and between the lower surface and the lower floor surface. A living room and garage are provided. Therefore, a large storage type storage room can be obtained without increasing the overall height of the building and without causing a significant cost increase. In this case, the height of the living room or the garage can be secured by setting the position of the floor surface of the living room or the garage provided below the storage room to be lower than the standard lower floor.

  The second invention is characterized in that a storage room is provided upward from the upper surface of the boundary between adjacent upper and lower floors, and a living room is provided between the upper surface of the storage room and the roof. In this case, it is preferable that the ceiling surface of the living room is formed higher than the ceiling surface of another living room formed on the upper surface of the boundary portion.

  According to a third aspect of the present invention, a room is provided above the upper surface of the boundary between the upper and lower floors adjacent to each other, and a storage room is provided between the upper surface of the room and the roof. In this case, it is preferable that the ceiling surface of the living room is formed lower than the ceiling surface of another living room formed on the upper surface of the boundary portion.

  According to the second and third aspects of the present invention, the living room and the storage room are arranged in a vertical relationship on the upper floor above the boundary between the upper and lower floors without providing an intermediate floor between the upper and lower floors. Is done. Also in this case, it is possible to obtain a large storage type storage room without increasing the height of the entire building and without causing a significant increase in cost.

  The fourth invention is characterized in that a living room is provided downward from the lower surface of the boundary between adjacent upper and lower floors, and a storage room is provided between the lower surface of the living room and the floor surface of the lower floor. In this case, the ceiling surface of the storage room formed between the lower surface of the living room and the floor surface of the lower floor is formed higher than the top of the foundation, and further, the floor surface of the storage room is formed with the boundary portion. It is preferable to form it lower than the floor surface of another living room formed on the lower surface. Further, the height position of the top edge of the foundation surrounding the storage room is formed lower than the height position of the top edge of the other foundation, or the height position of the top edge of the foundation other than the foundation surrounding the storage room is set. More preferably, it is formed higher than the height position of the top edge of the foundation surrounding the storage chamber.

  According to the fourth invention, without providing an intermediate floor between the upper and lower floors, the lower floor is provided with a room below the lower surface of the boundary between the upper and lower floors, and is stored between the lower surface and the lower floor surface. A room is provided. Therefore, a large storage type storage room can be obtained without increasing the overall height of the building and without causing a significant cost increase. In this case, the height of the living room above the storage room can be secured by setting the position of the floor of the storage room to be lower than the standard lower floor. Furthermore, if the height position of the top edge of the foundation surrounding the storage room is formed low or the height position of the top edge of the other foundation is formed high, the height of the living room and the storage room arranged above and below is further increased. It becomes easy to secure.

  In each of the first to fourth inventions, it is preferable that the height of the storage chamber is set to a range of 1.4 m or less. This is because the upper limit of 1.4 m is advantageous in that the storage room is not regarded as a living room in the Building Standard Law. In each of the first and fourth inventions, a part of the boundary between the upper and lower floors may be deleted so that the upper floor room or the step floor is blown up.

  Here, the following fifth to seventh inventions can be cited as inventions related to a frame structure suitable for obtaining the storage chamber.

  That is, the fifth invention comprises a main frame constituting the entire structure of the building and a skip frame forming a storage room, and the skip frame is supported by a load bearing wall provided between the columns of the main frame. It is characterized by. In this case, it is preferable that at least a part of the pillar of the main frame and the column of the skip frame are combined. Further, the columns of the main frame and the skip frame are both supported by the top end of the foundation, and the skip floor beam of the skip frame is provided in an area surrounded by these columns, and the outer periphery side of the skip floor beam and It is more preferable to connect the columns of the main frame facing each other.

  According to the fifth invention, the skip frame is supported by the load-bearing walls provided between the columns of the main frame, so that the structure calculation of the main frame is avoided as much as possible while maintaining the seismic strength of the skip frame. can do. And the space of a foundation can be used effectively by arrange | positioning the bearing wall which supports a skip frame between the pillars of a main frame. Further, if the pillar of the main frame is also used as the column of the skip frame, the skip frame can be used as a bearing wall of the main frame, which is advantageous in terms of cost. Furthermore, the main frame and the skip frame columns are supported on the top of the foundation, and the skip floor beam of the skip frame is provided in the area surrounded by each of these columns, the outer side of the skip floor beam and the main frame column facing it. By connecting them to each other, the pillar of the main frame does not get in the way when installing the skip frame.

  The sixth invention is characterized by comprising a main frame constituting the entire structure of the building and a skip frame forming a storage room, wherein the skip frame is set independently of the main frame. In this case, it is preferable that the skip frame is self-supporting by being connected to the foundation at a position different from the main frame. Furthermore, it is more preferable that the skip frame includes at least a plurality of skip pillars and skip floor beams connected to the skip pillars, a support fitting is provided on a side surface of the foundation, and the skip pillars are fixed to the support fitting. .

  According to the sixth invention, since the main frame and the skip frame are provided independently, the addition of the skip frame does not complicate the structure calculation of the main frame, and the mass production and the diversification of the layout are possible. It will be suitable. In order to set the skip frame independently, the skip frame may be connected to the foundation to be independent. In this case, it is conceivable to add a separate foundation for the skip frame. However, if a support bracket is provided on the side of the foundation used for the main frame and the skip column of the skip frame is fixed to the support bracket, the skip frame is skipped. A foundation dedicated to the frame is not required, which is advantageous in terms of cost.

  The seventh invention comprises a main frame constituting the entire structure of the building and a skip frame forming a storage room, the skip frame is connected to the upper floor beam of the main frame, the upper floor beam and the The skip frame and the upper floor structure are integrated. In this case, it is preferable that the skip frame is provided so as to be suspended from the main frame. Moreover, it is preferable to connect the skip floor beam and the upper floor beam of the skip frame with a bearing wall. Furthermore, it is preferable to use at least a part of the main frame pillar and the skip frame pillar.

  According to the seventh invention, the upper floor beam and the skip frame are integrated into the upper floor structure so that the skip frame can be regarded as an attached part of the upper floor beam in the structural calculation of the main frame. Therefore, the addition of the skip frame does not complicate the structural calculation of the main frame and is suitable for mass production. In addition, in order to configure the upper floor beam and the skip frame to be regarded as an integral upper floor structure, it is easily realized by connecting the skip floor beam of the skip frame and the upper floor beam with a bearing wall. be able to. Further, if the pillar of the main frame is also used as the column of the skip frame, the skip frame can be used as a bearing wall of the main frame, which is advantageous in terms of cost.

  In each of the above inventions, a skip floor or the like can be obtained without changing the height of the substructure member such as the outer wall as in the prior art, which is extremely advantageous in terms of cost.

  In this specification, the skip frame refers to a structure that constitutes a skip floor, and has, for example, a skip floor beam that constructs a skip floor as a specific frame structure, and in some cases, the skip floor beam. It also includes skip pillars connected to

(Explanation about the overall structure of the building)
Below, the building which is one embodiment which actualized the invention is demonstrated, referring FIG. In addition, FIG. 1 is a schematic longitudinal cross-sectional view which shows the whole building of this embodiment.

  As shown in FIG. 1, the building 10 of the present embodiment includes a first floor portion 12 as a lower floor formed on a foundation 11 and an upper floor formed continuously above the first floor portion 12. A second floor portion 13 and a roof portion 14 formed above the second floor portion 13 are provided. In addition, although detailed description is abbreviate | omitted here, the boundary part 15 of the 1st floor part 12 and the 2nd floor part 13 is well-known by each member between them including a 1st floor ceiling surface and a 2nd floor surface. It is configured.

  In the first floor portion 12 of the building 10, for example, a first living room 21, a second living room 22, a first storage room 23, a second storage room 24, and a garage 25 are formed. In the second floor portion 13 of the building 10, for example, a third living room 26 and a fourth living room 27 are formed.

  In the present embodiment, a plurality of skip portions 31 and 32 are constructed on the first floor portion 12. Specifically, the first living room 21 is constructed as a normal first-floor room, and the second living room 22 is constructed as a first skip portion 31 formed with a slightly higher floor position than the first living room 21, and the second living room. A first storage chamber 23 is formed below 22, that is, below the first skip portion 31. In addition, a garage 25 is constructed as an indoor garage on the opposite side of the second living room 22 across the first living room 21, and a second skip part 32 is built above the garage 25, and the second storage between the boundary part 15. A chamber 24 is formed.

  Each of the storage chambers 23 and 24 has a height in the space of 1 m to 1.4 m. The reason why the upper limit is 1.4 m is that it is not considered as a living room under the Building Standards Act, and the reason why the lower limit is 1 m is that the householders can easily enter the storage spaces of the storage rooms 23 and 24. This is to increase the storage capacity. However, 1m is not a necessary condition unless it is assumed that a family member will enter.

  And although the 1st skip part 31 and the 2nd skip part 32 are provided in the 1st floor part 12, and the 1st storage chamber 23 and the 2nd storage chamber 24 which have sufficient height as mentioned above are provided, they are provided. First, the height position of the boundary portion 15 between the first floor portion 12 and the second floor portion 13 is not different from a general two-story building. Further, in order to ensure the height of each storage chamber 23, 24, the floor surfaces of the first storage chamber 23 and the garage 25 are arranged below the top end 17 of the foundation 11. Conversely, the height of the first storage chamber 23 may be secured by setting the top end of the foundation 11 other than the portion corresponding to the first storage chamber 23 high. As a result, it is possible to secure intermediate floor storage and underfloor storage having a sufficient height that allows a householder to enter, with the same height as the conventional two-story building (see FIG. 10A). In order to make it easy for a family member to enter the second living room 22 and the storage rooms 23 and 24 from the first living room 21 or the floor at the height thereof, a skip stairs may be provided.

  In addition, although the large storage type storage rooms 23 and 24 are arranged in the vertical position of the living room or the like, the height of the entire building does not increase, and the conventional general two-story building And various members such as the outer wall can be shared. Therefore, there is no harmful effect due to the oblique line regulation, and the cost can be reduced.

  2A, a skip portion 43 may be provided above the living room 41 of the first floor portion 12, and the storage chamber 42 may be formed between the skip portion 43 and the boundary portion 15. . In this case, since the floor surface of the living room 41 is set below the top end 17 of the foundation 11, the height of the living room 41 and the height of the storage room 42 can be sufficiently secured. Further, as shown in FIG. 2 (b), the boundary portion 15 between the first floor portion 12 and the second floor portion 13 may not be provided above the skip portion 43, and may be used as the blow-off 46. Even in these cases, the same effect as in the example of FIG. 1 can be obtained.

  In addition, although not shown, in the second-floor portion 13, the living room and the storage room can be arranged vertically. That is, it is an example that a storage room is provided above the upper surface of the boundary 15 between the upper and lower floors adjacent to each other, and a living room is provided between the upper surface of the storage room and the roof portion 14. It is preferable to form the ceiling surface higher than the ceiling surface of another living room formed on the upper surface of the boundary portion 15. As another example, it is possible to provide a room above the upper surface of the boundary 15 between the upper and lower floors adjacent to each other, and to provide a storage room between the upper surface of the room and the roof portion 14. In this case, it is preferable that the ceiling surface of the room is formed lower than the ceiling surface of another room formed on the upper surface of the boundary portion 15.

(Description of frame model)
A frame model suitable for facilitating structural calculation when building the building 10 or the like and enabling mass production while being rich in variations will be described with reference to FIG.

  FIG. 3 is an explanatory view showing a variation of a suitable frame model when providing a storage space. The upper model of (a) to (d) is the frame model diagram, and the lower model is illustrated in the lower model. It is a structural system diagram. Both show frame models 51a-51d of two-story buildings, and how the skip frames 54a-54d for storage space construction are set with respect to the main frames 53a-53d constructed on the foundations 52a-52d. This is to explain whether it is preferable.

  The example shown in FIG. 3A is an example in which a storage space is arranged in the lower part of the first floor portion 12. In this example, the skip frame 54a is independently set inside the main frame 53a. Specifically, the skip frame 54a is connected to the foundation 52a separately from the main frame 53a. According to this example, the skip frame 54a does not need to be taken into account in the structural calculation of the main frame 53a. Therefore, there is an advantage that the conventional two-story building and the main frame 53a can be designed to be the same.

  The examples shown in FIGS. 3B to 3D are stored in the upper portion of the first floor portion 12, that is, on the lower surface side of the upper floor beams 55b to 55c, which is the boundary between the first floor portion 12 and the second floor portion 13. This is an example in which spaces are arranged.

  In FIG. 3B, the skip frame 54b is connected to the upper floor beam 55b of the main frame 53b, and a load bearing wall 56b that functions as an earthquake-resistant element of the main frame 53b is provided between the lower part of the skip frame 54b and the foundation 52b. It is arranged. A part of the skip frame 54b is also connected to a lower floor column 57b that connects the foundation 52b and the upper floor beam 55b. According to this example, the skip frame 54b can be regarded as a part of the load-bearing wall of the main frame 53b in the structural calculation of the main frame 53b. Therefore, the load-bearing wall of the main frame 53b is reduced and the portion is made into the skip frame 54b. There is an advantage that it can be entrusted and the conventional two-story building and the main frame 53b can be designed to be substantially the same.

  In FIG. 3 (c), the upper frame beam 55c and the skip frame 54c are connected by connecting the skip frame 54c to the upper floor beam 55c of the main frame 53c and forming at least one of the side surfaces of the skip frame 54c with a bearing wall. A load-bearing wall is constructed. According to this example, since the skip frame 54c can be regarded as an attached part of the upper floor beam 55c in the structural calculation of the main frame 53c, the conventional two-story building and the main frame 53c are designed to be the same. There are advantages that can be made.

  In FIG. 3 (d), a load bearing wall 56d that functions as an earthquake resistant element between the foundation 11d of the main frame 53d and the upper floor beam 55d is disposed below the skip frame 54d. This bearing wall 56d functions as a lower floor column 57d that connects the foundation 52d and the upper floor beam 55d together with the skip frame 54d. According to this example, in the structural calculation of the main frame 53d, the skip frame 54d can be regarded as a part of the load-bearing wall of the main frame 53d. There is an advantage that it can be entrusted and the conventional two-story building and the main frame 53d can be designed to be substantially the same.

(Description of concrete structure to realize the above frame model)
Next, a specific structure for realizing the frame model will be described with reference to FIGS. 4 is a front view showing a framework structure in the building 10 of FIG. 1, FIGS. 5 and 6 are partially enlarged views of FIG. 4, and FIG. 7 is a plan view showing a relationship between the foundation of the garage portion of FIG. It is.

  The building 10 described in FIG. 1 has a frame structure 61 in which steel is used as a frame on a foundation 11 as shown in FIG. 4, and the frame structure 61 is constructed by providing outer walls and other various building materials. Is. The frame structure 61 of the present embodiment is composed of the main frame 53 and the skip frame 54 which have been schematically described above.

  First, the main frame 53 will be described. Of the foundation 11, the foundations 11a and 11b corresponding to both sides of the first storage chamber 23 are set lower than the other foundations 11c and 11d assumed in a normal building. Has been. Conversely, the other foundations 11 c and 11 d can be installed so as to be higher than the foundations 11 a and 11 b corresponding to both sides of the first storage chamber 23. Lower floor pillars 63a to 63d are erected on the foundations 11a to 11d, respectively. The upper ends of the lower floor pillars 63a to 63d are connected to an upper floor beam 64 extending in the horizontal direction. The connecting structure is realized by, for example, bolting or welding corner fittings to each other.

  An upper floor material (not shown) is installed at the upper part of the upper floor beam 64, and a lower floor material is installed at the lower part thereof, so that the boundary 15 between the first floor part 12 and the second floor part 13 in FIG. (See FIG. 1) is constructed. The upper floor beams 64 are connected to the lower ends of the upper floor pillars 65a to 65d. Further, an upper floor ceiling beam 66 extending in the horizontal direction is connected to the upper ends of the upper floor pillars 65a to 65d. These connection structures are also realized by, for example, corner fittings being bolted or welded to each other, as in the case of the lower floor pillars 63a to 63d. The main frame 53 is constructed as described above.

  Next, the skip frame 54 will be described. In the present embodiment, as the skip frame 54, a skip frame 54a (see FIG. 3A) for forming the first storage chamber 23 and a skip frame 54b (FIG. 3 (FIG. 3) for forming the second storage chamber 24). b)).

  Of the skip frames 54a and 54b, the skip frame 54a for forming the first storage chamber 23 will be described with reference to FIG.

  The foundations 11a and 11b are provided with a pair of upper and lower support fittings 71a and 71b on the side surfaces facing each other. Each support metal fitting 71a, 71b is fixed to a steel frame (not shown) provided inside the concrete of the foundation 11a, 11b. Then, concrete is poured into the foundation mold in a state in which the respective support fittings 71a and 71b are fixed to the steel frame, whereby high-rigidity support fittings 71a and 71b integrated with the foundations 11a and 11b are obtained. .

  Skip pillars 72a and 72b are fixed to the respective support fittings 71a and 71b by bolting, welding or the like so as to extend in the vertical direction. In the drawing, only a pair of skip pillars 72a and 72b are visible for front view, but actually, the skip pillars 72a and 72b are respectively provided at positions that are at least four corners in plan view of the first storage chamber 23. Is provided.

  The upper ends of the skip pillars 72a and 72b are connected to a skip floor beam 73 extending in the horizontal direction. The connecting structure is realized by, for example, bolting or welding corner fittings to each other. In the skip floor beam 73, a skip floor material (not shown) is installed at the upper portion thereof, and a storage room ceiling member is installed at the lower portion thereof, so that a boundary portion between the second living room 22 and the first storage chamber 23 is constructed. .

  Next, a skip frame 54b for forming the second storage chamber 24 above the garage 25 will be described with reference to FIGS.

  The skip frame 54b also serves as a part of the column of the main frame 53, as described with reference to FIG. The lower floor pillars 63c and 63d of the main frame 53 are erected on the foundations 11c and 11d. In FIG. 6, only a pair of lower floor pillars 63 c and 63 d are visible for front view, but actually, as shown in FIG. 7, a plurality of other lower floor pillars 63 surround the garage 25 in plan view. Floor pillars 63e to 63j are erected at predetermined intervals on the foundations 11c and 11d. Note that many of the lower floor pillars 63c to 63j are lattice pillars or truss pillars for maintaining rigidity.

  Skip columns 76a to 76g that support the skip frame 54b from below are also erected on the foundations 11c and 11d so as to surround the garage 25. However, in the present embodiment, the skip frame 54b is set to have a depth smaller than that of the garage 25 when viewed in the depth direction when viewed from the front. For this reason, the foundation beam 77 is formed along the back end of the skip frame 54b. Is bridged between the foundations 11c and 11d, and a predetermined skip pillar 76e is erected on the foundation beam 77. Further, a part of the skip column 76 a forms a truss column by passing a truss member 78 between the lower level column 63 d and the skip frame 54 b also serves as a part of the main frame 53.

  The skip floor beam 79 is connected to the skip columns 76a to 76g and the lower floor columns 63c to 63j. The skip floor beam 79 is formed in a rectangular frame shape substantially matching a rectangular inner periphery surrounded by the skip columns 76a to 76g and the lower floor columns 63c to 63j in a plan view, and the skip columns 76a to 76g and the lower floor are formed. The inner peripheral side of the columns 63c to 63j and the outer peripheral side of the skip floor beam 79 are connected. The connection structure is realized by, for example, corner metal fittings being bolted or welded to each other, as in other connection structures. A skip floor material 75 (see FIG. 7) is installed at the top of the skip floor beam 79 and a garage ceiling material (not shown) is installed at the bottom thereof, so that the boundary between the second storage chamber 24 and the garage 25 is formed. Built.

  The upper ends of the skip columns 76 a to 76 g and the lower floor columns 63 c to 63 j are connected to the upper floor beam 64, but the upper ends of the skip columns 76 a to 76 g are the lengths up to the skip floor beam 79. It may be said.

  Moreover, it is good also as a frame structure shown in FIG. 8 instead of the example of FIG. This corresponds to the structure of the skip frame 54d shown in FIG. That is, in this skip frame 54d, a plurality of skip pillars 82a to 82d are connected between the upper floor beam 64 and the skip floor beam 81, and the bracing 83 is applied to each skip pillar 82a to 82d. Thus, at least a part of the side surface of the skip frame 54d is a bearing wall. Then, by connecting this bearing wall to the upper floor beam 64, the second storage chamber 24 constructed by the skip frame 54d can be regarded as a part of the upper floor portion of the main frame 53 for structural calculation. it can. Furthermore, by providing a bearing wall 84 composed of a lattice pillar including the lower floor pillar 63d between the foundation 11d and the skip floor beam 81, the bearing wall of the main frame 53 can be reduced, and various layout plans can be applied. It becomes possible to respond flexibly to this. When the frame model as shown in FIG. 3C is realized, the bearing wall 84 is omitted, and the skip frame 54d (the skip frame 54c in FIG. 3C) is connected to the upper floor beam 64. It is sufficient to configure so as to be connected only.

  Alternatively, the building 10 may be a unit building, and a plurality of building units constituting the unit building may each employ a frame structure including beams and columns, and the skip frame may be incorporated into a predetermined building unit or attached separately. . For example, the above-mentioned effects can be obtained while improving the workability of the on-site construction by fixing the skip frame in advance so as to be suspended from the ceiling beam of a predetermined lower floor building unit.

(Description of interior finish)
When the main frame 53 and the skip frame 54 are constructed as described above, for example, assuming that an earthquake has occurred, a difference may occur in the manner of shaking between the main frame 53 and the skip frame 54. If it does so, there exists a possibility that the interior material in both connection locations may be damaged. In particular, when the frame model described in FIGS. 3A and 3C is adopted, the possibility is high. A structure of a building that prevents such damage will be described with reference to FIG. 9 shows a structure in which the main frame 53 and the skip frame 54a are set independently as described with reference to FIGS. 3A and 5, and the first storage chamber 23 is provided below the skip frame 54a. This is based on the assumption that the second living room 22 is provided on the upper side.

  In the case of adopting such a frame structure in which the main frame 53 and the skip frame 54a are independent, when the building 10 is shaken due to an earthquake or the like, the main frame 53 and the skip frame 54a are individually shaken, and the width of the shake And their periods are different. Here, in the second living room 22 formed on the upper side of the skip frame 54a, the floor 91 is attached to the skip frame 54a side, and the outer wall 92 is attached to the main frame 53 side. As a result, if the interior material that fills the gap between the floor 91 and the outer wall 92 is fixed to them, a part of the interior material may be damaged. In order to avoid this, the outer wall 92 provided on the main frame 53 and the inner wall 93 extending from the floor 91 provided on the skip frame 54a are not fixed.

  That is, the outer wall 92 is provided with a window frame 94 corresponding to the second living room 22, and a window base 95 that closes the gap between the window frame 94 and the inner wall 93 is provided. The window base 95 is fixed to the grooved metal fitting 96 to which the inner wall 93 is fixed by screws 97, and the outer wall 92 side of the window base 95 is placed on the upper surface of the L-shaped metal fitting 98 fixed to the outer wall 92. Not too much. The relative position is determined so that a sufficient clearance C of about several centimeters is formed between the window frame 94 and the window base 95.

  With this configuration, even if the main frame 53 and the skip frame 54a swing individually, the window base 95 that swings together with the skip frame 54a and the window frame 94 that swings together with the main frame 53 are not connected to each other and both Since the clearance C is provided between them, the interior materials such as the window base 95, the inner wall 93, the floor 91 and the like are not damaged.

  In the example of FIG. 9, a cover 99 is provided on the window frame 94 in order to improve the aesthetics so that the gap due to the clearance C is not visible from the second living room 22. It is preferable that the cover 99 extends indoors to such an extent that the indoor side end thereof comes into contact with the window base 95.

  In addition, a fire-proof iron plate 100 is provided below the window base 95 so as to be bridged between the grooved metal fitting 96 and the L-shaped metal fitting 98. The indoor side end of the fireproof iron plate 100 is fixed to the grooved metal fitting 96 by screws 97, but the outdoor side end is positioned to the same extent as the outdoor side end of the window base 95, and is simply L It is merely placed on the metal mold 98. Therefore, the fireproof iron plate 100 swings together with the window base 95, and the interior material is not damaged and the fireproof performance can be maintained.

  In addition to the above, the connection between the floor 91 and the inner wall 93 is not performed, and the inner wall 93 slides with respect to the floor 91 when the main frame 53 and the skip frame 54a swing individually. You may comprise. In this case, the floor 91 is preferably formed so as to extend slightly to the outdoor side from the lower end of the inner wall 93.
