Summary of the Invention

Problems to be Solved by the Invention

[0005] Here, in the above-described configuration, since the receiving portion is provided in the outer entrance space, the receiving portion is likely to be visible from the outside through the open portion of the outer entrance space, which may damage the appearance of the entrance portion.

[0006] Furthermore, since the interior entrance space needs to be formed using a separate building unit from the building unit that constitutes the exterior entrance space, the manufacturing cost of the building unit is incurred when constructing the entrance area.

[0007] This invention has been made in view of the above circumstances, and its main objective is to provide a modular apartment building that can reduce manufacturing costs when constructing the entrance area and can also prevent damage to the appearance of the entrance area. [Means for solving the problem]

[0008] To solve the above problems, the first invention provides a modular apartment building, which is a modular apartment building composed of a plurality of building units, wherein the plurality of building units include an entrance unit that constitutes a common entrance area which serves as an entrance to the apartment building, and the entrance unit is provided with an outer entrance space that is open to the outside on the girder surface of the entrance unit and an inner entrance space that is separated from the outer entrance space by a partition wall, and the partition wall is formed in an L-shape in plan view, having a first wall that extends in the girder direction of the entrance unit at the middle of the entrance unit in the girder direction and a second wall that extends in the girder direction at the middle of the entrance unit in the girder direction, the first wall is provided with a common entrance that allows entry and exit from the outer entrance space to the inner entrance space, and the second wall is provided with a receiving section that receives deliveries that are put in from the outer entrance space, and the receiving section is provided embedded in the second wall.

[0009] According to the first invention, an outer entrance space and an inner entrance space are provided inside the entrance unit that constitutes the entrance area of ​​an apartment building. In this case, it becomes possible to construct the entrance area using a single building unit (i.e., an entrance unit). Therefore, manufacturing costs can be reduced when constructing the entrance area.

[0010] Furthermore, the outer entrance space and the inner entrance space are separated by a partition wall, which is formed in an L-shape in plan view, having a first wall extending in the direction of the entrance unit's girder and a second wall extending in the direction of the entrance unit's gable. In this case, the second wall is positioned perpendicular to the girder surface of the entrance unit (i.e., the girder surface where the outer entrance space is open to the outdoors). The second wall is provided with a receiving section for receiving deliveries, and this receiving section is embedded in the second wall. With this configuration, the receiving section can be made less visible from the outdoor-opening side of the outer entrance space. Therefore, the appearance of the entrance area can be kept from being spoiled.

[0011] In the unit-type apartment building of the second invention, the second wall portion extends from the first wall portion on the side opposite to the girder surface.

[0012] In the entrance unit, if the girder surface on the side where the outer entrance space is open to the outdoors is called the open girder surface, then in the second invention, the second wall extends from the first wall toward the opposite side from the open girder surface. In this case, the second wall is located behind the first wall, and the receiving portion is provided on the second wall at the rear. Therefore, the receiving portion can be made less visible from the outdoor-opening side of the outer entrance space. This further reduces the deterioration of the appearance of the entrance area.

[0013] The third invention, a modular apartment building, is provided in the second invention with an outlet in the receiving section that allows the delivered items received in the receiving section to be retrieved from the inner entrance space.

[0014] According to the third invention, residents of an apartment building can retrieve their delivered items from the receiving area immediately upon entering the inner entrance space through the common entrance. Therefore, this configuration is convenient for retrieving delivered items.

[0015] The fourth invention is a modular apartment building in which, in any of the first to third inventions, the first wall section is configured to have a plurality of panel sections arranged in the width direction of the wall, and the plurality of panel sections include a door panel section including an entrance door provided at the common entrance, a first panel section, and a second panel section.

[0016] The size of entrance areas in apartment buildings varies. Therefore, to accommodate these various entrance area sizes, it is conceivable to prepare multiple types of entrance units with different lengths in the girder direction. However, if the length of the entrance unit in the girder direction differs, the width of the first wall section extending in that direction will also change. Furthermore, the first wall section includes the door panel section, which includes the entrance door, and there are multiple types of door panels with different widths. As a result, many types of wall sections will be generated for each length of the entrance unit in the girder direction, and also for each width of the door panel section. However, this would increase the design and management burden.

[0017] Therefore, in view of these points, the fourth invention is configured such that the first wall section has a plurality of panel sections arranged in the wall width direction, and these plurality of panel sections include a door panel section, as well as a first panel section and a second panel section. In this configuration, in order to accommodate a plurality of types of door panel sections with different widths, a plurality of types of first panel sections with different widths are prepared in advance, and the first panel sections are selected so that the sum of the width of the door panel section and the width of the first panel sections becomes a predetermined width. Furthermore, it is possible to determine the number of second panel sections according to the length of the entrance unit in the girder direction, that is, according to the wall width of the first wall section.

[0018] Therefore, according to the configuration of the present invention, by combining the first panel portion and the second panel portion, a large number of types of first wall portions can be constructed. In this case, since the types of the first panel portion and the second panel portion to be prepared can be relatively few, the design burden and the management burden can be reduced in constructing a plurality of types of first wall portions.

Embodiments for Carrying Out the Invention

[0020] Hereinafter, an embodiment in which the present invention is embodied will be described with reference to the drawings. In the present embodiment, a unit-type apartment house constructed by combining a plurality of building units is embodied. The unit-type apartment house 10 is, for example, a multi-story rental apartment. Hereinafter, prior to the description of the unit-type apartment house 10, first, the configuration of the building unit 20 will be briefly described. FIG. 4 is a perspective view showing an outline of the building unit 20.

[0021] As shown in FIG. 4, the building unit 20 has a rectangular parallelepiped shape and includes four columns 21 arranged at its four corners, and four ceiling girders 22 and four floor girders 23 that connect the upper and lower ends of each column 21, respectively. A rectangular parallelepiped-shaped skeleton (frame) is formed by the columns 21, the ceiling girders 22, and the floor girders 23. The column 21 is made of square tubular steel. The ceiling girder 22 and the floor girder 23 are made of channel steel having a U-shaped cross section.

[0022] Between the opposing ceiling girders 22 on the long side of the building unit 20, a plurality of ceiling joists 25 are spanned. Also, between the opposing floor girders 23 on the long side of the building unit 20, a plurality of floor joists 26 are spanned. The ceiling joists 25 are made of lip channel steel, and the floor joists 26 are made of square steel. Although illustration is omitted, a ceiling finish material is attached to the lower surface side of the ceiling joists 25, and a floor finish material is attached to the upper surface side of the floor joists 26. Further, wall finish materials such as an outer wall finish material and an inner wall finish material are attached to the side surface portion of the building unit 20.

[0023] The building unit 20 is manufactured in a manufacturing factory and, after manufacturing, is transported to the construction site by a truck. At the construction site, each transported building unit 20 is installed at a predetermined installation location and combined with each other. Thereby, the unitized apartment house 10 is constructed.

[0024] Subsequently, the configuration of the unitized apartment house 10 will be described based on FIGS. 1 to 3. FIG. 1 is a plan view showing the configuration around the entrance portion 16 in the unitized apartment house 10. FIG. 2 is a plan view showing an enlarged entrance portion 16. FIG. 3 is a perspective view of the entrance portion 16 as seen from the front side of the house. In FIGS. 1 and 2, only the columns 21 of the building unit 20 are shown.

[0025] As shown in FIG. 1, the unitized apartment house 10 includes a plurality of dwelling units 11 in which residents live and a common portion 12 shared by the residents of each dwelling unit 11. The common portion 12 has a common corridor 14 provided for each floor portion, a common staircase 15 connecting the common corridors 14 on the upper and lower floors, and an entrance portion 16 which is an entrance portion to the unitized apartment house 10.

[0026] As shown in Figures 1 and 3, the entrance area 16 is located on the first floor of the modular apartment building 10 and has an outer entrance space 17 that is open to the outdoors and an inner entrance space 18 that is located further inside the building than the outer entrance space 17. The outer entrance space 17 is a concave space that is open to the outdoors and is covered from above by the second floor. The inner entrance space 18 is continuous with the common corridor 14 on the first floor.

[0027] The outer entrance space 17 and the inner entrance space 18 are separated by a partition wall 31. The partition wall 31 is provided with a shared entrance / exit 33 for entering and exiting from the outer entrance space 17 to the inner entrance space 18. The shared entrance / exit 33 is provided with an entrance door 34, which opens and closes the shared entrance / exit 33.

[0028] The multiple building units 20 that make up the modular apartment building 10 include a building unit 20 for the entrance (hereinafter referred to as the entrance unit 20A) that constitutes the entrance area 16. The configuration of the entrance unit 20A will be described below. In Figure 2, each column 21 of the entrance unit 20A is shown in black for clarity.

[0029] As shown in Figure 2, the entrance unit 20A has a girder surface 38 (in other words, the long side) facing the front of the modular apartment building 10. For the sake of clarity, in Figure 2, the girder surface 38 of the entrance unit 20A is shown with a dashed line. Inside the entrance unit 20A, there is an outer entrance space 17 that is open to the outside on the girder surface 38 of the entrance unit 20A, and an inner entrance space 18 that is separated from the outer entrance space 17 by a partition wall 31. In the following description, the girder surface 38 of the entrance unit 20A will also be referred to as the open girder surface 38. The partition wall 31 corresponds to the "partition wall" described in the claims.

[0030] The entrance unit 20A has a partition wall section 35 on the girder surface opposite to the open girder surface 38, and partition wall sections 36 and 37 on each end surface. The outer entrance space 17 and the inner entrance space 18 are surrounded by these partition wall sections 36 and 37. Each partition wall section 35 to 37 is composed of, for example, a pair of opposing exterior wall panels and a base frame provided between each exterior wall panel.

[0031] The partition wall 31 is formed in an L-shape in plan view. The partition wall 31 has a first wall 41 that extends in the girder direction (in other words, the long side direction in plan view) of the entrance unit 20A in the middle part (more specifically, approximately the center) in the girder direction (in other words, the short side direction in plan view) of the entrance unit 20A, and a second wall 42 that extends in the girder direction of the entrance unit 20A in the middle part in the girder direction of the entrance unit 20A. In this case, the first wall 41 is arranged in a direction parallel to the open girder surface 38 of the entrance unit 20A, and the second wall 42 is arranged in a direction perpendicular to the open girder surface 38.

[0032] The first wall section 41 has one end in the wall width direction connected to the partition wall section 36, and the other end in the wall width direction connected to the second wall section 42. The second wall section 42 has one end in the wall width direction connected to the partition wall section 35, and the other end in the wall width direction connected to the first wall section 41. In this case, the second wall section 42 extends from the first wall section 41 toward the side opposite to the open girder surface 38.

[0033] The exterior entrance space 17 is formed in an L-shape in plan view along the L-shaped partition wall 31. The exterior entrance space 17 has a front space 17a that is open to the outside on the open girder surface 38 of the entrance unit 20A, and a rear space 17b that extends from the front space 17a to the opposite side from the open girder surface 38. The interior entrance space 18 is formed inside the L-shaped partition wall 31 in plan view.

[0034] A shared entrance 33 is provided in the first wall section 41 of the partition wall section 31, and a mailbox section 45 is provided in the second wall section 42. The mailbox section 45 is embedded in the second wall section 42 and is positioned to penetrate the second wall section 42. More specifically, an opening 47 is formed in the second wall section 42 that connects the outer entrance space 17 (more specifically, the inner space section 17b) and the inner entrance space 18, and the mailbox section 45 is positioned to be inserted through this opening 47. The mailbox section 45 corresponds to the "receiving section".

[0035] The mailbox section 45 is provided with an insertion slot 51 into which mail can be inserted from the outer entrance space 17, and an outlet 52 into which the inserted mail can be retrieved from the inner entrance space 18. Multiple insertion slots 51 and outlets 52 are provided for each dwelling unit 11. The mailbox section 45 is also provided with multiple doors 53 for opening and closing each insertion slot 51, and multiple doors 54 for opening and closing each outlet 52.

[0036] The mailbox section 45 has an outer overhang 45a that extends outward toward the entrance space 17 beyond the second wall section 42, and an inner overhang 45b that extends inward toward the entrance space 18 beyond the second wall section 42. The overhang dimension of the outer overhang 45a is smaller than the overhang dimension of the inner overhang 45b. Note that the overhang dimensions of each overhang section 45a and 45b may be the same, for example.

[0037] Next, we will explain the configuration of the first wall section 41.

[0038] The first wall section 41 is composed of a plurality of panel sections 61 to 63 arranged in the width direction of the wall. The plurality of panel sections 61 to 63 include a door panel section 61 which includes the entrance door 34, a first panel section 62 adjacent to the door panel section 61, and a second panel section 63 adjacent to the first panel section 62. The door panel section 61 includes the entrance door 34 as well as a frame section 56 disposed on the periphery of the entrance door 34. Furthermore, the first panel section 62 and the second panel section 63 are composed of, for example, a pair of opposing exterior wall surface materials and a base frame provided between each exterior wall surface material.

[0039] According to the above-described configuration of the first wall section 41, it is possible to construct multiple types of first wall sections 41 by changing the width of the first panel section 62 or changing the number of second panel sections 63. Therefore, this point will be explained below.

[0040] In order to meet customer needs, housing manufacturers that produce modular apartment buildings 10 offer multiple types of door panels 61 with different widths W1. For example, door panels 61 with widths W1 of 1250 mm, 1500 mm, and 2000 mm are available.

[0041] Furthermore, to accommodate multiple types of door panel sections 61 with different widths W1, home builders offer multiple types of first panel sections 62 with different widths W2. For example, first panel sections 62 with widths W2 of 750mm and 500mm are available.

[0042] When constructing the first wall section 41, the combination of the door panel section 61 and the first panel section 62 may be as follows: If a door panel section 61 with a width W1 of 1250 mm is used, then a first panel section 62 with a width W2 of 750 mm is used. If a door panel section 61 with a width W1 of 1500 mm is used, then a first panel section 62 with a width W2 of 500 mm is used. If a door panel section 61 with a width W1 of 2000 mm is used, then the first panel section 62 is not used. In short, the door panel section 61 and the first panel section 62 are combined such that the sum of the width W1 of the door panel section 61 and the width W2 of the first panel section 62 (total width) is a predetermined width (2000 mm).

[0043] Furthermore, to meet customer needs, home builders offer multiple types of entrance units 20A with different lengths in the girder direction. For example, entrance units 20A are available with girder lengths L of 4500mm, 5000mm, and 5500mm.

[0044] In each of the multiple types of entrance units 20A, which have different lengths L in the girder direction, the distance H between the second wall section 42 and the partition wall section 37 is the same in all cases. In other words, the above distance H is fixed in each of the multiple types of entrance units 20A. For this reason, among the multiple types of entrance units 20A, the larger the length L in the girder direction, the larger the wall width of the first wall section 41 provided within the entrance unit 20A.

[0045] In housing manufacturers, a second panel section 63 with a width L3 of, for example, 500 mm is provided. When constructing the first wall section 41, the number of second panel sections 63 included in the first wall section 41 is adjusted according to the wall width of the first wall section 41. For example, if the length L in the girder direction of the entrance unit 20A is 4500 mm, the wall width of the first wall section 41 is small, so only one second panel section 63 is included. If the length L in the girder direction of the entrance unit 20A is 5000 mm, the wall width of the first wall section 41 is 500 mm larger, so two second panel sections 63 are included. In this case, the two second panel sections 63 are arranged side by side in the wall width direction of the first wall section 41.

[0046] As described above, with the first wall section 41 composed of multiple panel sections 61 to 63, many types of first wall sections 41 can be constructed by combining the panel sections 61 to 63. In this case, since only a relatively small number of types of panel sections 61 to 63 need to be prepared, the design and management burdens can be reduced when constructing multiple types of first wall sections 41.

[0047] Furthermore, among the wall sections within the entrance unit 20A, the wall sections other than the first wall section 41 (for example, partition wall sections 35-37) have a constant wall width regardless of the type of entrance unit 20A (length L in the girder direction).

[0048] As described in detail above, the configuration of this embodiment provides the following excellent effects.

[0049] An outer entrance space 17 and an inner entrance space 18 are provided inside the entrance unit 20A that constitutes the entrance area 16. In this case, the entrance area 16 can be constructed using a single building unit 20A (i.e., an entrance unit 20A). Therefore, manufacturing costs can be reduced when constructing the entrance area 16.

[0050] Furthermore, the outer entrance space 17 and the inner entrance space 18 are separated by a partition wall 31, which is formed in an L-shape in plan view, having a first wall 41 extending in the girder direction of the entrance unit 20A and a second wall 42 extending in the gable direction of the entrance unit 20A. In this case, the second wall 42 is positioned perpendicular to the open girder surface 38 of the entrance unit 20A. A mailbox section 45 capable of receiving mail is provided in the second wall section 42, and the mailbox section 45 is positioned embedded in the second wall section 42. With this configuration, the mailbox section 45 can be made less visible from the outdoor open side of the outer entrance space 17. Therefore, the appearance of the entrance section 16 can be prevented from being spoiled.

[0051] The second wall section 42 extends from the first wall section 41 toward the opposite side of the entrance unit 20A from the open girder surface 38. In this case, the second wall section 42 is located further back from the first wall section 41, and the mailbox section 45 is provided on the second wall section 42 at the rear. Therefore, the mailbox section 45 can be made less visible from the outdoor open side of the outer entrance space 17. This further reduces the deterioration of the appearance of the entrance section 16.

[0052] The mailbox section 45 has an outer overhang 45a that extends outward toward the entrance space 17 beyond the second wall section 42, and an inner overhang 45b that extends inward toward the entrance space 18 beyond the second wall section 42. The overhang dimension of the outer overhang 45a is smaller than that of the inner overhang 45b. This further suppresses the deterioration of the appearance of the entrance section 16. The mailbox section 45 may also be provided so as not to extend outward toward the entrance space 17 beyond the second wall section 42.

[0053] The mailbox section 45 is provided with an opening 52 that allows mail received in the mailbox section 45 to be retrieved from the inner entrance space 18. In this case, residents of the apartment building can enter the inner entrance space 18 from the common entrance 33 and immediately retrieve their mail from the mailbox section 45. Therefore, this configuration is convenient for retrieving mail.

[0054] The present invention is not limited to the embodiments described above, and may be implemented, for example, as follows.

[0055] (1) In the above embodiment, a mailbox section 45 (corresponding to a receiving section) is provided in the second wall section 42 of the partition wall section 31. However, instead of or in addition to the mailbox section 45, a delivery box capable of receiving parcels may be provided. In this case, the delivery box corresponds to the receiving section.

[0056] (2) The configuration of the partition wall 31 is not necessarily limited to the configuration of the above embodiment. For example, in the example shown in Figure 5, the partition wall 71 inside the entrance unit 70 is formed in an L-shape in plan view, having a first wall 73 extending in the girder direction of the entrance unit 70 and a second wall 74 extending in the gable direction of the entrance unit 70, similar to the above embodiment. However, in the partition wall 71 of this example, unlike the partition wall 31 of the above embodiment, the second wall 74 extends from the first wall 73 toward the open girder surface 77 of the entrance unit 70. In this configuration, of the outer entrance space 81 and the inner entrance space 82 separated by the partition wall 71, the inner entrance space 82 is formed in an L-shape in plan view along the partition wall 71, and the outer entrance space 81 is formed inside the partition wall 71.

[0057] A mailbox section 85 is provided in the second wall section 74. The mailbox section 85 is positioned embedded in the second wall section 74. In this configuration as well, since the second wall section 74 is positioned perpendicular to the open-side girder surface 77 of the entrance unit 70, the mailbox section 85 can be made less visible from the open side of the outer entrance space 81 (in other words, the front side of the house). This helps to prevent the appearance of the entrance section from being spoiled.

[0058] (3) In the above embodiment, the first wall portion 41 of the partition wall portion 31 was configured to include a plurality of panel portions 61 to 63, but for example, the partition wall portion 31 may be configured with a single panel portion.

[0059] (4) In the above embodiment, the mailbox section 45 was provided in a state where it penetrated the second wall section 42. However, for example, a recessed section open to the outer entrance space 17 (rear space section 17b) may be provided in the second wall section 42, and the mailbox section may be housed in that recessed section. In this case as well, since the mailbox section is embedded in the second wall section 42, it is possible to prevent damage to the appearance of the entrance section. In this configuration, mail received in the mailbox section will be taken out from the outer entrance space 17 through the slot. [Explanation of symbols]
