[Effects of the Invention]

[0011] The present invention provides for a multi-unit housing complex and its construction method as described above. A 3-4 story multi-unit housing complex resembling a studio apartment can be constructed in an extremely short period (about 10 days for a 3-story building) and at low cost by utilizing existing shipping containers, pre-finishing the interior in a factory, transporting them to the site, and forming load-bearing walls around the containers. Furthermore, because the interior is already completed, it can be occupied immediately after completion. Additionally, the use of sturdy shipping containers provides high sound insulation, creating a comfortable living space. [Brief explanation of the drawing]

[0012] [Figure 1] This is an internal configuration diagram showing one embodiment of a multi-unit dwelling according to the present invention. [Figure 2]This figure shows the construction method for the first floor of a multi-unit residential building according to the present invention. [Figure 3] This figure shows a method for forming load-bearing walls in the construction method of a multi-unit residential building according to the present invention. [Figure 4] This figure shows the construction method for the second and third floors of a multi-unit residential building according to the present invention. [Figure 5] This figure shows the state of formation of load-bearing walls in the construction method for multi-unit housing according to the present invention. [Figure 6] This figure shows a method for installing common passages and staircases in the construction method of an apartment building according to the present invention. [Modes for carrying out the invention]

[0013] Embodiments for carrying out the present invention will be described in detail with reference to the attached drawings. The method for constructing a multi-unit dwelling according to the present invention is characterized by comprising a container renovation process, a foundation work process, a first-floor construction process, a second-floor construction process, an extension process, and a staircase installation process. The method for constructing a multi-unit dwelling according to the present invention will be described in detail below for each process.

[0014] Container conversion process The construction method for apartment buildings according to the present invention primarily utilizes refurbished shipping containers. There are international standards for shipping containers, and the containers used in the method according to the present invention are preferably those with external dimensions of 6,058 mm in length, 2,438 mm in width, and 2,591 mm in height. For example, two rooms can be constructed using three containers of this size (see Figure 1). In this case, three containers constitute a two-room unit.

[0015] This container conversion process involves carrying out renovation work at a factory to make the interior of a container suitable for habitation, after removing unnecessary parts of the walls as needed. Specifically, floorboards, wallboards, and ceilingboards are installed inside the existing container, and kitchen, toilet, bathroom, and other equipment is installed. Underneath the floorboards, piping for water supply to the kitchen, etc., and drainage pipes from the kitchen, etc., are installed.

[0016] In the example shown in FIG. 1 where three containers 1, 2, and 3 are taken as one unit, after constructing the floor boards, wall boards, and ceiling boards for containers 1 and 3, the entrance door 4 and window 5 are installed, and a shoe box 6 and storage space 7 are provided near the entrance. Also, for the container 2 arranged in the middle, a partition wall 8 is provided in the center, and a kitchen 9, toilet 10, washstand 11, and bathroom 12 are symmetrically arranged on both sides thereof. Although not shown in the figure, lighting fixtures are of course arranged.

[0017] Foundation construction process This process is the process of constructing the foundation 15 at the construction site. The construction of the foundation 15 can be carried out by a general method.

[0018] 1st floor construction process Each of the modified containers 1 to 3 constituting the above unit is transported to the site by a separate vehicle and placed on the foundation 15 in unit form (see FIG. 2). For example, when there are six rooms on the first floor, three units composed of the above modified containers 1 to 3 will be placed on the foundation 15. After placing a predetermined number of units on the foundation 15, a panel frame 16 is arranged so as to surround the periphery of each unit and the space between the units, and concrete is placed between the panel frame 16 and the outer surface of each unit to form a shear wall 17 around while concealing the units (see FIG. 3). Thus, the modified containers 1 to 3 forming each unit are integrated, and at the same time, the units are integrated with each other to construct the first floor (see FIG. 4).

[0019] 2nd floor construction process In this process, the work is substantially the same as in the first-floor construction process described above. Specifically, the second-floor units are stacked on top of the first-floor units, panel frames 16 are placed around and between the second-floor units, concrete is poured between the panel frames 16 and the outer surfaces of the units, and load-bearing walls 17 are formed around the units while concealing them. In this way, each of the renovation containers 1 to 3 that make up the unit is integrated, and each unit is integrated with the others, thus constructing the second floor (see Figure 4). The panel frames used here can be reused from those used in the first-floor construction. This second-floor construction work can be started in about three days after the completion of the first-floor construction process.

[0020] Expansion process This process is necessary when constructing a building with three or more floors. The two-story construction process is repeated on top of the second floor the required number of times to construct the third floor or higher (see Figures 4 and 5). The construction of the third floor can begin about three days after the completion of the two-story construction process. While the apartment building according to the present invention is mainly envisioned to be two to three stories high, it is also possible to construct buildings with four or more stories.

[0021] Stair installation process This process involves adding a common corridor 18 and staircase 19 to the second floor and above (see Figure 6).

[0022] The apartment building utilizing existing containers according to the present invention is constructed by the above construction method, and in order to make it habitable, unnecessary parts of the walls are removed as necessary from the existing containers, and floorboards, wallboards and ceilingboards are installed on them, and a kitchen 9, toilet 10, washbasin 11, bathroom 12 and other equipment are installed, and piping for water supply equipment to the kitchen 9, etc. and drainage pipes from the kitchen 9, etc. are installed on the underside of the floorboards, and lighting fixtures are attached to the ceiling. Multiple remodeled containers 1 to 3 are fixed on a foundation, and the first floor is constructed by integrating the remodeled containers 1 to 3 through concrete poured around them.

[0023] Furthermore, the remodeling containers 1 to 3 for the construction of the second floor are stacked on top of each of the remodeling containers 1 to 3 on the first floor, and the remodeling containers for the construction of the second floor are integrated and constructed via concrete poured around them, and the building has a second floor with a common passageway 18 and a staircase 19 attached.

[0024] In addition, the third floor is constructed by stacking the remodeling containers 1-3 for the construction of the third floor on top of each of the remodeling containers 1-3 on the second floor, and integrating them through concrete poured around them. Furthermore, there may be a fourth floor constructed in the same manner as the third floor.

[0025] In the example above, three containers make up two rooms, but it goes without saying that one container can also be used to make up one room. [Industrial applicability]

[0026] The present invention provides for a multi-unit housing complex and its construction method as described above. A 3-4 story multi-unit housing complex resembling a studio apartment can be constructed in an extremely short period (about 10 days for a 3-story building) and at low cost by utilizing existing shipping containers, pre-finishing the interior by removing unnecessary parts of the walls as needed at a factory, transporting the containers to the site, and forming load-bearing walls around the containers. Furthermore, because the interior is already completed, it can be occupied immediately after completion. In addition, because sturdy shipping containers are used, it has high sound insulation properties, creating a comfortable living space, and thus has great industrial applicability.
