  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In addition, the same code | symbol is attached | subjected to the common structure in each figure. In addition, although the apartment house 1 demonstrated below has a some hierarchy, unless there is particular notice, it demonstrates on the 1st floor as an example for convenience of explanation.

  FIG. 1 is a first floor plan view of an apartment house 1 as the present embodiment. As shown in FIG. 1, the apartment house 1 has an outer peripheral wall 2 that partitions an internal space and an outdoor space. The outer peripheral wall 2 includes, for example, an external finish layer formed by connecting exterior panel materials made of lightweight cellular concrete (ALC) having a coating film as a waterproof layer formed on the surface side, and phenol foam, for example. It is composed of a heat insulation layer constructed by connecting the foamed resin-based insulation panel material along the inner surface of the exterior finish layer, and a finish material such as a wall cloth affixed to the surface of the gypsum boat and gypsum board However, it is not particularly limited. The outer peripheral wall 2 should just have a predetermined fireproof performance and waterproof performance.

  The inner side of the outer peripheral wall 2 in the apartment house 1, that is, the internal space, includes a common unit 3 and a dwelling unit 4 including a plurality of dwelling units 4 a. The shared section 3 includes a shared hallway 33 and a shared staircase 32 in a folded form that communicates between the shared hallways 33 on each floor. The outer peripheral wall 2 facing the common hallway 33 on the first floor is formed with an opening 31 that communicates the common part 3 with the external space, and the opening 31 is provided with a common entrance door 34. The upper part of the shared part 3 on the top floor is covered with a roof, and thereby, the shared part 3 of all levels is partitioned from the external space. Note that the shared unit 3 may be provided with a mechanical lifting means such as an elevator, or may further be provided with a blow-off.

  The shared unit 3 and the dwelling unit 4 (each dwelling unit 4a) are partitioned by a partition wall 5. As shown in FIG. 2, the partition wall 5 includes a first wall 5 a provided on the dwelling unit 4 side and a second wall 5 b provided on the common unit 3 side.

  The first wall 5a is composed of a columnar light iron stud material having a substantially U-shaped cross section or a substantially B-shaped cross section, and a first base material 54 erected at a predetermined interval, and a two-layer reinforced gypsum board And a first face member 51 attached to the first base material 54 by a fixing tool such as a screw. The first base material 54 is positioned at the lower end and the upper end by the lower runner material fixed to the floor surface and the upper runner material fixed to the upper floor beam or floor slab and connected to each other. The reinforced gypsum board constituting the first face material 51 is a gypsum board whose fire resistance is reinforced by mixing an inorganic fiber material in the core part, and one sheet has a thickness of 21 mm and is adjacently reinforced. The joint part (joint part) with the gypsum board is stuck so that it does not overlap on the inner surface side and the outer surface side. The first wall portion 5a is a partition wall having fire resistance performance of 1 hour specified by laws and regulations such as the Building Standards Act, and in addition to the 1 hour fire heat irradiation test from the first face material 51 side, This also clears the fire heat irradiation test from the base material 54 side.

  The second wall portion 5b is made of a columnar light iron stud material having a substantially U-shaped cross section, and is composed of a second base material 55 erected at a predetermined interval and a double-layered gypsum board. And a second face member 52 attached to a fixing member such as a screw. The second base material 55 is positioned at the lower end and the upper end by the lower runner material fixed to the floor surface and the upper runner material fixed to the upper floor beam or floor slab and connected to each other. The gypsum board constituting the second face material 52 has a thickness of 12.5 mm, and the joint (joint part) with the adjacent reinforced gypsum board does not overlap on the inner surface side and the outer surface side. It is affixed to.

  In such a partition wall 5, since the fire resistance is secured by the first wall portion 5a having the first face material 51 and the first base material 54 to which the first face material 51 is attached, It is not necessary to give the wall 5b fire resistance. Therefore, the degree of freedom of selection of the second face material 52 is high, and it is easy to provide decorativeness and design. In addition, since the fire resistance is ensured by the configuration of only the first face material 51 and the first base material 54, another face material is provided between the first base material 54 and the second base material 55. Etc., and the thickness of the entire partition wall 5 can be reduced.

  Further, the first base material 54 and the second base material 55 stand between the first face material 51 and the second face material 52 in a state of being separated from each other in a substantially staggered manner in a plan view. (See FIG. 10). Since the first base material 54 and the second base material 55 are arranged in a staggered manner, it is difficult to interfere with each other, and the first wall portion 5a and the second wall portion 5b can be brought close to each other. The thickness of the partition wall 5 can be further reduced.

  Moreover, between the 1st wall part 5a and the 2nd wall part 5b, it does not have structural members of walls, such as another surface material, but is the cavity part 56. FIG. The hollow portion 56 is filled with a filler 53 made of a fibrous material having flexibility such as rock wool and glass wool. This filler 53 is excellent in fire resistance, sound insulation, and heat insulation, and can delay the arrival of fire heat to the first base material 54 when, for example, a fire breaks out from the shared portion 3 side. The fire resistance of can be further increased. Further, the filler 53 contributes to the sound insulation between the common unit 3 and the dwelling unit 4 and the improvement of the thermal environment of the dwelling unit 4. Furthermore, since the first base material 54 and the second base material 55 are arranged in a staggered manner in a plan view, a narrowed portion is generated in the cavity 56 even if the thickness of the entire partition wall 5 is reduced. Therefore, it is possible to suppress a decrease in performance due to the filler 53 being crushed.

  Further, by using the surplus cavity 56 between the filler 53 and the first face member 51 after filling with the filler 53, such as a power cable, a communication cable, a gas pipe, a water supply pipe, a hot water supply pipe, It is possible to pass wiring and piping related to facilities and information. Thereby, the maintenance of the aesthetics of the common part 3 and the protection of wiring and piping from the heat from the common part 3 side are possible.

  A moisture-proof layer 58 is formed of a moisture-proof film such as polyethylene on the surface of the first face member 51 on the dwelling unit 4 side (see broken lines in FIGS. 2 and 3). Furthermore, an interior finishing layer 59 composed of a gypsum board as an interior member and a wall cloth pasted on the surface of the gypsum board is formed on the surface of the moisture-proof layer 58 on the dwelling unit 4a side.

  A wall cloth as a finishing material is attached to the surface of the second face material 52 on the shared part 3 side and finished. The wall cloth is combined with the gypsum board, which is the second face material 52, to limit interior decorations stipulated by laws and regulations such as the Building Standards Act (to finish walls and ceilings with semi-incombustible materials or materials with higher performance (Restriction rules). In selecting the second face material 52 and the finish material, any material can be used as long as the finish material alone or the combination of the second face material 52 and the finish material satisfies the above interior restriction regulations. For example, it is possible to use brick, ceramic tile, metal plate, glass, stone, mortar, plaster or the like alone or a plaster board as a base. Further, the second face material may also serve as a finishing material. It is also possible to provide a portion having an uneven shape or a curved surface shape on the surface. Thus, since the 2nd wall part 5b has the freedom degree of selection of a finishing material, and the freedom degree of a form, it can give finishing with high decoration property and design to the common part 3. FIG. Further, without modifying the first wall portion 5a (that is, maintaining the fire resistance performance of the partition wall 5), only by processing the second face material 52 and the finishing material, a wall-embedded switch, outlet, wall It is also possible to easily install an attached lighting fixture or the like.

  The partition wall 5 including the first wall portion 5a and the second wall portion 5b is formed with an opening 6 serving as an entrance to each dwelling unit 4a. The opening 6 is provided with a dwelling unit entrance door 7. It has been. The dwelling unit entrance door 7 is a so-called “fire door” having a predetermined fire prevention performance, and constitutes a specific fire prevention equipment prescribed by laws and regulations such as the Building Standard Law. The dwelling unit entrance door 7 includes a door frame 71 and a door main body 73 attached to the door frame 71 via a hinge 72. The door frame 71 is configured by combining, for example, a long hollow material formed by bending a steel plate into a rectangular frame shape. The door main body 73 includes, for example, a rectangular frame member 73a made of a steel material and two face members 73b and 73c made of a steel plate and fixed to both sides of the frame member 73a. A heat insulating material for enhancing heat insulation, a reinforcing material for enhancing rigidity, and the like can be provided in the hollow portion inside.

  In the opening 6 of the partition wall 5, the opening size of the first wall 5a including the first face member 51 is smaller than the opening size of the second wall 5b including the second face member 52, that is, the first The edge of the face material 51 protrudes beyond the edge of the second face material. As for the door frame 71, the flat surface by the side of the dwelling unit 4 is the surface by the side of the common use part 3 in the edge part (part protruded rather than the 2nd surface material 52) by the side of the opening 6 of the 1st surface material 51. And is fixed by a fixing tool such as a screw. That is, the dwelling unit entrance door 7 is continuous with the first face material 51. With this configuration, in order to ensure fire resistance of the partition wall 5, a member having fire resistance is interposed between the dwelling unit entrance door 7 and the first face material 51 (for example, the first face material). It is not necessary to provide an additional surface material having fire resistance equivalent to that of 51 so as to be wound in the direction of the entrance door 7 and the fire resistance of the partition wall 5 can be ensured by a simple method.

  Further, the surface of the door body 73 on the shared part 3 side is the surface of the wall cloth which is the finished surface of the partition wall 5 on the shared part 3 side (the thickness of the wall cloth is less than 1 mm and is extremely thin; It is set back to the dwelling unit 4 side than the surface of 52). More specifically, the surface of the door main body 73 on the shared portion 3 side substantially coincides with the center position of the thickness (including about 220 mm in the present embodiment) of the partition wall 5 including the finishing of both surfaces. It is about 110mm backward from the finished surface of the common part. With this configuration, a shadow is formed on the side wall surface of the common part 3 of the partition wall 5 and the entire entrance door 7 including the door frame 71 is difficult to see from the common part 3 side. And design properties can be improved.

  Further, at the periphery of the opening 6 in the partition wall 5, an additional surface material (that is, a 12.5 mm thick double plaster board) 52 a having the same configuration as the second surface material 52 is provided in the direction toward the entrance door 7. The gap between the edge of the second face member 52 and the door frame 71 is covered by the additional face member 52a, and the finishing material (wall cloth) of the second face member 52 Finished with the same finishing material. With this configuration, it is possible to further enhance the sense of quality, design, and decoration of the shared portion 3. In addition, as an additional surface material 52a, you may use another plate-shaped member within the range which satisfy | fills interior restrictions. In addition, as shown in FIGS. 4A to 4C, an embedded lighting fixture 8 such as a downlight can be provided in the portion of the additional surface material 52 a (the portion where the common portion wall surface is involved). In addition, what is shown with the code | symbol 71a in FIGS.

  In the present embodiment, the additional face material 52a and the second face material 52 form 90 degrees in a sectional view, but the form of the additional face material 52a is as shown in FIGS. 5 (a) to 5 (c). It may be anything. That is, in the opening 6 provided in the partition wall 5, the opening size of the second wall 5 b (second face material 52) is further increased, and the angle formed between the additional face material 52 a and the second face material 52 is increased. The door frame 71 and the second surface have an obtuse angle (for example, 135 degrees) (that is, the frontage dimension or height dimension gradually increases from the common part entrance door 7 toward the common part 3). You may attach so that the space | gap between the materials 52 may be plugged up. This configuration can be applied not only to the left and right vertical frame sides of the door frame 71 but also to the upper frame side, and the angle formed between the additional surface material 52a and the second surface material 52 in each direction is 90. The angle can be an arbitrary angle of less than 180 degrees. For example, it is possible to change the angle only on the upper frame side or to make it asymmetrical. Moreover, this form can also be employ | adopted not only for the dwelling part entrance door 7 part but the periphery of the area | region containing the retreating wall part 9 mentioned later. As described above, by providing a portion where the angle formed between the additional face material 52a and the second face material 52 is an obtuse angle in cross-sectional view, the shared portion 3 can be provided with novelty. For example, by applying this configuration to the suspension side of the dwelling unit entrance door 7, the door body 73 can be greatly opened, and the convenience when people go in and out and luggage can be improved. .

  Moreover, as shown to Fig.6 (a)-(c), the additional surface material 52a is made into a bowl shape in several steps (a frontage dimension or a height dimension is stepped toward the common part 3 direction from the common part entrance door 7). It may be formed so as to be bent. Also in this example, the same effect as the example shown in FIG. 5 is exhibited, and various combinations are possible.

  As shown in FIGS. 7 to 9, a receding wall 9 can be provided at a position adjacent to the dwelling unit entrance door 7 (opening 6). The receding wall portion 9 is provided in a region where the second wall portion 5b is partially removed. The receding wall portion 9 is thinner than the second wall portion 5b or closer to the first wall portion 5a. It is comprised so that the surface by the side of the 1st base material of 1 wall part 5a may be covered. The surface of the receding wall portion 9 is closer to the dwelling unit 4a side than the surface of the partition wall 5 on the shared unit 3 side, and is substantially aligned with the surface of the door main body 73 of the dwelling unit entrance door 7. The receding wall portion 9 can be provided with, for example, a nameplate, a post, an intercom entrance cordless handset, an umbrella stand, or a lighting fixture. In addition, the receding wall part 9 can also be provided in the right-and-left both sides of the dwelling unit entrance door 7, and can also be provided in the upper frame side. By combining these, it is possible to obtain a generally saddle shape or a gate shape in a front view. By providing the nameplate or the like on the receding wall portion 9, the nameplate or the like is difficult to protrude on the shared portion 3 side, so that it is difficult to prevent a resident or the like passing through the shared portion 3 from passing. Moreover, by providing the receding wall portion 9 on the side where the door main body 73 opens (the side opposite to the suspension base), a space for retracting the body when the door main body 73 is opened from the shared portion 3 side is expanded, and the dwelling unit 4a is opened. Easy access. Further, the surface of the receding wall portion 9 can be finished in the same manner as the dwelling unit entrance door 7, and in this case, the unity in appearance with the dwelling unit entrance door 7 can be enhanced.

  Here, FIG. 11 is a cross-sectional view showing a connection portion between the boundary wall 10 and the partition wall 5. The boundary wall 10 is a wall provided at the boundary between adjacent dwelling units 4a for the purpose of preventing the spread of fire between a plurality of adjacent dwelling units 4a, and is defined as a partition wall by laws and regulations such as the Building Standard Law. It has predetermined fire resistance (for example, fire resistance for 1 hour). That is, in addition to the one hour fire heat irradiation test from the one dwelling unit 4a side, the fire heat irradiation test from the other dwelling unit 4a side is also cleared. The boundary wall 10 is composed of a pair of face materials 10a and a base material 10b serving as a base for fixing the face material 10a. The face material 10a is configured by stacking two plaster boards having a thickness of 9 mm, for example. Moreover, the base material 10b consists of the light iron stud material erected at predetermined intervals along the extending direction of the face material 10a, for example. The base material 10b is provided for each of the pair of face materials 10a, and the base materials 10b are separated from each other. In addition, the cavity in the boundary wall 10 is filled with a filler 53 having sound insulation properties such as rock wool.
