Description

[Technical field]

[0001] The present invention relates to an apartment building, and more particularly to a slab-type apartment building. [Background technology]

[0002] In a slab-type apartment building, a balcony is located on one side of the building (this side is called the front), and a common corridor and entrance hall are located on the opposite side (this side is called the back). Patent Document 1 discloses a slab-type apartment building. In this apartment building, the pillar at the end of the front side is shifted toward the back side relative to the other pillars, and an L-shaped beam is provided between this pillar and the adjacent pillar on the front side. The dwelling units on both ends have excellent openness as three sides face the outside, but with this configuration, there is no need to provide pillars at the corners on the front side of the apartment building, which can further enhance the openness.

[0003] [Patent Document 1] JP 2015-155610 A Summary of the Invention [Problem to be solved by the invention]

[0004] As mentioned above, the apartment building disclosed in Patent Document 1 can increase the openness of the dwelling units at both ends. However, it is difficult to increase the openness of the dwelling units between the dwelling units at both ends because windows cannot be installed at the boundaries with the adjacent dwelling units on both sides. If the position of the dwelling unit boundary on the front side is shifted depending on the dwelling unit, a dwelling unit boundary that does not contact the adjacent dwelling units can be formed on the side of the dwelling unit, making it possible to install windows. However, such a configuration makes the building structure complex and makes it difficult to ensure the building strength.

[0005] An object of the present invention is to provide an apartment building that can increase the openness of the dwelling units between the two ends while ensuring the strength of the building. [Means for solving the problem]

[0006] The apartment house of the present invention is an apartment house in which a plurality of dwelling units are arranged in a straight line, one side along the longitudinal direction is the front side where the balconies of the dwelling units are arranged, and the other side along the longitudinal direction is the back side where a common corridor is arranged, and adjacent first and second dwelling units are provided between the dwelling units at both ends. The apartment house has a back side beam that extends linearly along the back side between both ends in the longitudinal direction of the apartment house. The first dwelling unit has a front side boundary that is the boundary on the front side, and a side boundary that is connected to the front side boundary and does not face the second dwelling unit. The apartment house has a first beam that extends along the front side boundary of the first dwelling unit and also extends along a part of the side boundary, and a second beam that faces the balcony of the second dwelling unit. A window is provided in the part of the side boundary, and the second beam is a reverse beam. and has a cross-sectional area larger than that of the first beam. . Effect of the Invention

[0007] According to the present invention, it is possible to provide an apartment building that can increase the openness of the dwelling units between the two end dwelling units while ensuring the strength of the building. [Brief description of the drawings]

[0009] Some embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of an apartment house 1 according to a first embodiment of the present invention, FIG. 2 is a cross-sectional view of the apartment house 1 taken along line AA in FIG. 1, and FIG. 3 is a cross-sectional view of the apartment house 1 taken along line BB in FIG. 1. FIG. 4 is an enlarged view of part E in FIG. 1, FIG. 4(a) is a plan view taken along line CC in FIG. 2 and FIG. 4(b) is a plan view taken along line DD in FIG. 2 and FIG. 3. In the following description, X means the longitudinal direction (beam direction) of the apartment house 1, and Y means the transverse direction (beam direction) of the apartment house 1. One side of the apartment house 1 along the longitudinal direction X (parallel to the longitudinal direction X) on which the balconies of each dwelling unit are arranged is called the front side S1 of the apartment house 1. The other side of the apartment house 1 along the longitudinal direction X, which is the side opposite to the front side S1 of the apartment house 1, is called the back side S2 of the apartment house 1. The two surfaces provided at both ends of the longitudinal direction X of the apartment house 1 and extending along the lateral direction Y are called gable surfaces S3 and S4 of the apartment house 1.

[0010] Referring to FIG. 1, the apartment house 1 is a so-called slab-type apartment house in which multiple dwelling units are arranged in a straight line. The number of floors of the apartment house 1 is not particularly limited, but is usually about 4 to 15 floors. A third dwelling unit R3 is arranged at both ends of the longitudinal direction X of the apartment house 1, and multiple dwelling units are arranged between the two third dwelling units R3. In the following description, among the multiple dwelling units arranged between the two third dwelling units R3, two specific dwelling units adjacent to each other are referred to as the first dwelling unit R1 and the second dwelling unit R2. There are two pairs of the first dwelling unit R1 and the second dwelling unit R2. The living / dining / kitchen area and balcony V of each dwelling unit are arranged on the front surface S1 of the apartment house 1. The balcony V is also provided on the gable surfaces S3 and S4 of the apartment house 1, and the third dwelling unit R3 has two balconies V. However, the balconies V on the gable surfaces S3 and S4 may be omitted. A common corridor 4 connecting to each dwelling unit and an entrance to each dwelling unit (not shown) are located on the back surface S2 of the apartment building 1. On the back surface S2 of the apartment building 1, the boundaries between each dwelling unit are aligned in the short side direction Y, and the common corridor 4 is straight. Stairs 2 and an elevator 3 are located in the common corridor 4.

[0011] In the front S1 of the apartment house 1, the second dwelling unit R2 is recessed in the short direction Y relative to the first dwelling unit R1. As a result, as shown in FIG. 4(a), the first dwelling unit R1 has a boundary on the balcony V side facing the front S1 of the apartment house 1 (hereinafter referred to as the front boundary 8a) and a side boundary 9b. The side boundary 9b is on an extension line of the boundary 9a between the first dwelling unit R1 and the second dwelling unit R2, and protrudes from the second dwelling unit R2 to the front S1 side. In other words, the side boundary 9b is a dwelling unit boundary of the first dwelling unit R1 that is connected to the front boundary 8a and does not face the second dwelling unit R2. The boundary 9 on the second dwelling unit R2 side of the first dwelling unit R1 consists of the boundary 9a that contacts the second dwelling unit R2 and the side boundary 9b that does not contact the second dwelling unit R2. In this embodiment, two pairs of second dwelling units R2 are adjacent to each other. Therefore, in the apartment house 1 of this embodiment, the two adjacent second dwelling units R2 are recessed in the short direction Y relative to the other dwelling units. The position of the second dwelling units R2 in the longitudinal direction X is not limited, but in this embodiment, they are located at the center of the apartment house 1 in the longitudinal direction X. This makes the apartment house 1 symmetrical, which is preferable in terms of the balance of structural strength and appearance, but an asymmetrical shape is also acceptable.

[0012] A first beam B1 is provided on the front S1 side of the first dwelling unit R1. The first beam B1 is composed of a first portion 12a connected to the column C3 and extending along the front boundary 8a of the first dwelling unit R1, and a second portion 13a extending along a part of the side boundary 9b (a section between the connection with the front boundary 8a and the connection with the second beam B2 (column C4)). The first portion 12a and the second portion 13a are perpendicular to each other. In this embodiment, the first beam B1 is generally L-shaped when viewed from above, with the long side of the L shape extending along the front boundary 8a and the short side of the L shape extending along a part of the side boundary 9b. Therefore, in this embodiment, the first portion 12a is longer than the second portion 13a, but the first portion 12a may be the same length as the second portion 13 or shorter than the second portion 13a. The first beam B1 is a normal beam, and the balcony V protrudes outward from the first beam B1. As shown in Fig. 2, the balcony V of the first dwelling unit R1 is provided with a balustrade wall 5a. No beam is provided on the outer edge of the balcony V.

[0013] A second beam B2 is provided on the front S1 side of the second dwelling unit R2. The second beam B2 is a reverse beam (meaning a beam whose upper end protrudes upward from the upper surface of the floor slab of the dwelling unit, and whose lower end may be flush with the lower surface of the floor slab or may protrude below the lower surface of the floor slab) facing the balcony V of the second dwelling unit R2. The front boundary 8b of the second dwelling unit R2 is parallel to the second beam B2, and the balcony V is between the second dwelling unit R2 and the second beam B2. As shown in FIG. 3, the second beam B2 is also used as a part of the boundary wall of the balcony V, and a handrail wall 5b is provided at the top of the second beam B2 to compensate for the lack of handrail height. The second dwelling unit R2 has a so-called out-frame structure, and since beams and columns do not protrude into the dwelling unit on the balcony V side, even the corners of the room can be effectively utilized.

[0014] The third dwelling unit R3 at both ends has a front boundary 8c and a boundary on the gable side S3, S4 side (hereinafter referred to as gable side boundary 11). A third beam B3 is provided on the front S1 side of the third dwelling unit R3. The third beam B3 is composed of a first portion 12b connected to the column C2 and extending along the front boundary 8c of the third dwelling unit R3, and a second portion 13b extending along a part of the gable side boundary 11 (the section between the connection with the front boundary 8c and the column C1). The first portion 12b and the second portion 13b are perpendicular to each other. In this embodiment, the third beam B3 is generally L-shaped when viewed from above. That is, the first beam B1 and the third beam B3 have the same or similar shape.

[0015] On the balcony V side, the column C1 installed on the gable faces S3 and S4 of the housing complex 1 and the three columns C4 to C6 facing the second dwelling unit R2 are recessed from the other columns. For this reason, as described above, the column C3 and the column C4 are connected by the L-shaped first beam B1. The strength against earthquake forces of an L-shaped beam is lower than that of a straight beam. For this reason, the second beam B2 is made larger in cross section than a normal beam as an inverted beam to ensure the insufficient strength. The cross-sectional area of ​​the second beam B2 is made larger than the other beams. In particular, in this embodiment, the second beam B2 is provided continuously over two spans (more generally, it is preferable that the second beam B2 is provided continuously over two spans or more), so that it is easy to ensure the strength.

[0016] Beams (fourth beam B4) other than the first to third beams B3 on the front S1 side of the apartment building 1 and beams (fifth beam B5) other than the third beam B3 on the gable faces S3 and S4 sides are normal beams and may be flat beams. Beams (sixth beam B6) on the back S2 side of the apartment building 1 are all normal beams. Gable walls 7 are provided on the gable faces S3 and S4, and partition walls 14 are provided between the dwelling units. Columns are provided on the front S1 side and back S2 side of the apartment building 1, and column C7 is also provided near the center of the short side direction Y of the gable faces S3 and S4.

[0017] As shown in FIG. 4(b), a window W2 is provided in a portion of the side boundary 9b of the first dwelling unit R1. As described above, the portion of the side boundary 9b of the first dwelling unit R1 is the section between the connection with the front boundary 8a and the connection with the second beam B2 (column C4), specifically, directly below the second portion 13a of the first beam B1. The window W2 is preferably a window that allows access to the balcony V, such as a bay window, but may be a waist window. In addition, the front boundary 8a is provided with a window W1 that allows access to the balcony V. As a result, as shown in FIG. 4(b), the window W1 of the front boundary 8a and the window W2 of the side boundary 9b are arranged in a mutually orthogonal direction, and these windows W1 and W2 are arranged close to each other, so that the view from the corner of the dwelling unit (in this embodiment, the living / dining / kitchen area) is expanded, improving the openness or feeling of openness. This configuration also promotes the flow of outside air through the two windows W1, W2, improving the ventilation of the dwelling unit. Small pillars 12 (or mullions) are provided at the corners to support the sash frames, but removing the pillars 12 and using glass will further improve the sense of openness. Sleeve walls (not shown) may be provided on either or both of the window W1 at the front boundary 8a and the window W2 at the side boundary 9b.

[0018] A window W2 similar to that of the first dwelling unit R1 is also provided in a part of the gable side boundary 11 of the third dwelling unit R3 (directly below the second portion 13b of the third beam B3). In conventional slab-type collective housing, even in the third dwelling unit R3, which is a so-called corner room, due to layout restrictions, the window W1 may only be provided on the balcony V side of the living / dining / kitchen area. Even when a window is provided in the part of the gable side boundary 11, the window W1 on the front side boundary 8c and the window W2 on the gable side boundary 11 may be separated from each other due to the pillars installed in the corner portion, making it difficult to create a sense of openness. In other words, in conventional slab-type collective housing, the advantage of the corner room is often not fully utilized. According to this embodiment, the window W2 can be provided in the gable sides S3 and S4 of the third dwelling unit R3 close to the window W1 on the front side boundary 8c. However, a part of the boundary 11 on the gable side of the third dwelling unit R3 (directly below the second portion 13b of the third beam B3) may be made of drywall without providing a window W2. Even in this case, the same sense of openness as in the conventional case can be obtained.

[0019] In addition, even in units other than the corner units, where windows could only be installed at the front boundary 8a, windows W2 can be installed at the side boundary 9b. In this embodiment, four units R1, R2, and R3 with excellent openness can be secured per floor, thus increasing the value of the entire apartment building 1.

[0020] The first beam B1 and the third beam B3 are not limited to an L-shape. FIG. 5 shows a modified example of the third beam B3. Although not shown, the same applies to the first beam B1. As shown in FIG. 5(a), the third beam B3 has a portion 15 extending at an angle other than a right angle with respect to the longitudinal direction X. That is, the second portion 13b of the third beam B3 has a portion 15 that faces in an oblique direction with respect to the first portion 12b. Alternatively, as shown in FIG. 5(b), the third beam B3 may have a portion 16 that is curved in a curved shape with respect to the longitudinal direction X. In either case, it is preferable to arrange the window W2 in the straight portion.

[0021] FIG. 6 shows a plan view of an apartment house 101 according to the second embodiment. The configuration and effects that are not described are the same as those of the first embodiment. At the front S1 of the apartment house 101, the first dwelling unit R1 protrudes in the short direction Y relative to the second dwelling unit R2. As a result, in this embodiment, the first dwelling unit R1 has a front boundary 8a and a side boundary 9b. There are two pairs of the first dwelling unit R1 and the second dwelling unit R2, but the two pairs of the first dwelling units R1 are adjacent to each other, and the second dwelling unit R2 is arranged on both sides of them. The position of the first dwelling unit R1 in the longitudinal direction X is not limited, but in this embodiment, it is located in the center of the apartment house 101 in the longitudinal direction X. This makes the apartment house 101 symmetrical, which is preferable in terms of structural strength and appearance, but an asymmetrical shape is also acceptable. In this embodiment, the front of the window W2 on the side boundary 9b of the first dwelling unit R1 is open (there is no apartment building 101), further improving the sense of openness. Also, on the front face S1 of the apartment building 101, the third dwelling units R3 on both ends protrude in the short direction Y relative to the adjacent second dwelling unit R2. For this reason, windows can be installed on three sides of the third dwelling unit R3, further improving the sense of openness.

[0022] FIG. 7 shows a plan view of an apartment house 201 according to the third embodiment. The configuration and effects that are not described are the same as those of the first embodiment. In this embodiment, the apartment house 201 is divided into first to third blocks 21, 22, and 23 as a whole, and the first block 21, the second block 22, and the third block 23 are arranged in this order in the longitudinal direction X. The second block 22 is offset toward the balcony V side in the short direction Y from the first block 21, and the third block 23 is offset toward the balcony V side in the short direction Y from the second block 22. That is, in this embodiment, in each of the two pairs of the first dwelling unit R1 and the second dwelling unit R2, the first dwelling unit R1 and the second dwelling unit R2 are arranged in the same order. Specifically, in both pairs at the front S1 of the apartment house 201, the second dwelling unit R2 is arranged on the left side of the first dwelling unit R1. As a result, in this embodiment as well, the first dwelling unit R1 has a front boundary 8a and a side boundary 9b. In this embodiment as well, the front of the window W2 on the side boundary 9b of the first dwelling unit R1 is open (there is no apartment building 201), further improving the sense of openness.

[0023] FIG. 8 shows a floor plan of an apartment house according to another modification. In the example shown in FIG. 8(a), only one pair of the first dwelling unit R1 and the second dwelling unit R2 is provided. In this example, three dwelling units with excellent openness provided at the side boundary 9b or the gable side boundary 11 can be secured per floor. In the example shown in FIG. 8(b), four pairs of the first dwelling unit R1 and the second dwelling unit R2 are provided. In this example, six dwelling units with excellent openness provided at the side boundary 9b or the gable side boundary 11 can be secured per floor. The example shown in FIG. 8(c) is a modification of the third embodiment, in which the second block 22 is offset from the first block 21 in the short direction Y to the opposite side of the balcony V, and the third block 23 is offset from the second block 22 in the short direction Y to the opposite side of the balcony V. In the example shown in Fig. 8(d), two rows of dwelling units are provided, and a core space 17 is provided between the two rows of dwelling units, where stairs, elevators, common corridors, etc. are arranged. This example can be considered as two apartment buildings 1 of the first embodiment combined together, and eight dwelling units with excellent openness provided with windows W2 on the side boundary 9b or gable side boundary 11 can be secured per floor. The example shown in Fig. 8(d) can also be applied to the second embodiment and the modified examples shown in Figs. 8(a) and (b). [Explanation of symbols]
