[0041] FIG. 8 shows the piping of the first floor (121) and the second floor (122) of a multi-unit dwelling (1) according to one embodiment.

[0042] FIG. 9 is a cross-sectional view schematically illustrating an integrated vertical equipment space of a multi-unit dwelling (1) according to one embodiment.

[0043] Referring to FIG. 1, a multi-unit dwelling (1) according to one embodiment may include a central core (11) and a module (12).

[0044] The central core (11) can be positioned vertically from the ground. The central core (11) can be fixed. A common space, such as an elevator or a corridor, can be provided in the central core (11).

[0045] Modules (12) can be arranged around a central core (11). For example, modules (12) can be arranged in a shape where the center is penetrated by the central core (11). Multiple modules (12) may be provided. Each module (12) can be stacked coaxially along the longitudinal direction of the central core (11).

[0046] This module (12) may include a plurality of layers. Each of the plurality of layers may have the same planar structure. The plurality of layers may be stacked coaxially around a central core (11) to form a single module (12). At this time, each layer may be arranged in a shape that is rotated and displaced at a certain angle.

[0047] That is, among the multiple layers, layer n can be arranged in a shape rotated by a certain angle in one direction relative to layer n+1.

[0048] Accordingly, each layer constituting the module (12) may have the same configuration in a planar manner, but may have a configuration of different functions located in the vertical direction of the module (12).

[0049] The number of layers constituting one module (12) may vary as needed, and multiple modules (12) may each be composed of layers having the same number and rotational displacement.

[0050] Additionally, the n-th layer of one of the multiple modules (12) can be arranged so that the same configuration is positioned vertically with the n-th layer of another module (12).

[0051] The present invention will be described in detail below using an example of a multi-unit dwelling (1) in which four layers (121, 122, 123, 124) constitute one module (12).

[0053] Referring to FIG. 2, multiple housing units (H1, H2, H3, H4, H5) capable of accommodating multiple households may be spaced apart along the circumferential direction on one floor. Each housing unit (H1, H2, H3, H4, H5) may be designed with the same structure.

[0054] Each housing unit (H1, H2, H3, H4, H5) may be provided with multiple rooms. For example, a housing unit (H1) may include a first room (R1), a second room (R2), a third room (R3), etc., which have different functions. The roof (F) of the housing unit on the nth floor may be provided as a terrace accessible from the housing unit on the n+1th floor.

[0055] Referring to FIGS. 3 to 6, one module (12) may include a first layer (121), a second layer (122), a third layer (123), and a fourth layer (124).

[0056] As previously mentioned, since the structures of the first layer (121), second layer (122), third layer (123) and fourth layer (124) are all identical, the components of each layer will be described in detail using the first layer (121) as an example.

[0057] Referring to FIG. 3, the first layer (121) may include an inner portion (1211) and an outer portion (1212).

[0058] The inner portion (1211) may be arranged to surround the central core (11). The inner portion (1211) may form a space extending radially outward from the central core (11).

[0059] The outer periphery (1212) may form a space that protrudes radially outward from the outer surface of the inner periphery (1211).

[0060] For example, the inner portion (1211) and the outer portion (1212) can be formed integrally. The inner portion (1211) and the outer portion (1212) can be combined with each other to form a plurality of housing units.

[0061] At this time, the number of housing units can be determined according to the shape of the outer periphery (1212). The outer periphery (1212) may be composed of a plurality of outer periphery units spaced apart in the circumferential direction of the inner periphery (1211). The plurality of housing units may be spaced apart in the circumferential direction around the central core (11).

[0062] The present invention will be described in detail below using an example of a multi-unit dwelling (1) in which five housing units (H1, H2, H3, H4, H5) are arranged on one floor and five outer units are provided.

[0063] As described above, the common space is not rotated along the longitudinal direction of the central core (11). However, the angle at which the housing units (H1, H2, H3, H4, H5) are located may differ from floor to floor.

[0064] For example, the inner and outer portions of the second layer (122) can be rotated and displaced by a certain angle in one direction relative to the inner portion (1211) and outer portion (1212) of the first layer (121).

[0066] Referring to FIGS. 3 to 6, the first layer (121), the second layer (122), the third layer (123), and the fourth layer (124) may be stacked sequentially along the longitudinal direction of the central core (11). However, each layer may be rotated by a certain angle in one direction relative to the lower layer.

[0067] Accordingly, the roof of the outer periphery (1212) of the nth floor can be composed of a terrace of the n+1th floor. That is, the roof (F) of the housing unit (H1, H2, H3, H4, H5) of the nth floor can be composed of a terrace of the housing unit (H1, H2, H3, H4, H5) of the n+1th floor.

[0068] Ultimately, the roof (F1) formed by the outer unit of the first floor (121) can be used as a terrace for the second floor (122), the roof (F2) formed by the outer unit of the second floor (122) can be used as a terrace for the third floor (123), and the roof (F3) formed by the outer unit of the third floor (123) can be used as a terrace for the fourth floor (124). Additionally, the roof formed by the fourth floor (124) of one module (12) can be used as a terrace for the first floor (121) of another module (12) stacked thereon.

[0069] Due to the rotational displacement shape of each floor, the terraces of the multi-unit dwelling (1) according to one embodiment may each have a ceiling height of two or more floors. In addition, each floor may have a vertically independent terrace.

[0071] Rotation angle of the n+1th layer relative to the nth layer ( ) can be determined by the number of layers constituting one module (12) and the number of housing units or outer periphery units.

[0072] For example, the rotation angle of the n+1th layer with respect to the nth layer ( ) can be determined by the following equation.

[0073]

[0074] At this time, θ is the rotation angle, A is the number of layers, and B may be the number of outer periphery units.

[0075] In this specification, a module (12) consisting of four layers and five outer periphery units for each layer is described as an example, so the rotational displacement may be 18 degrees.

[0076] Below, we will explain using an example of a multi-unit dwelling (1) in which each floor is rotated 18 degrees clockwise relative to the lower floor.

[0077] The second layer (122) may be rotated 18 degrees clockwise relative to the first layer (121), the third layer (123) may be rotated 18 degrees clockwise relative to the second layer (122), and the fourth layer (124) may be rotated 18 degrees clockwise relative to the third layer (123).

[0078] Accordingly, the multi-unit dwelling (1) according to one embodiment can have different exteriors for each floor by arranging each floor at different angles.

[0079] In addition, as described above, the first layer of one module can be arranged at the same angle as the first layer of another module. That is, the first layer (121) of each of the plurality of modules (12) can all be the same as in FIG. 3, the second layer (122) can all be the same as in FIG. 4, the third layer (123) can all be the same as in FIG. 5, and the fourth layer (124) can all be the same as in FIG. 6.

[0080] Referring again to FIG. 3, the first floor (121) may further include inner columns (1213) and outer columns (1214).

[0081] The inner columns (1213) may be provided in multiple numbers. Each inner column (1213) may be positioned adjacent to the outer surface of the inner portion (1211). Each inner column (1213) may be spaced apart along the circumferential direction.

[0082] The outer columns (1214) may be provided in multiple numbers. Each outer column (1214) may be positioned adjacent to the outer surface of the outer portion (1212). Each outer column (1214) may be spaced apart along the circumferential direction.

[0083] The plurality of inner columns (1213) and the plurality of outer columns (1214) can be alternately spaced apart along the circumferential direction around the central core (11).

[0084] Additionally, in the nth floor and the n+1th floor, each inner column (1213) or outer column (1214) may be arranged in the same position in the vertical direction. A plurality of inner columns (1213) arranged in the first floor (121) may be arranged coaxially with each corresponding plurality of inner columns (1213) arranged in the second floor (122). Additionally, a plurality of outer columns (1214) arranged in the first floor (121) may be arranged coaxially with each corresponding plurality of outer columns (1214) arranged in the second floor (122).

[0085] For example, the inner column (P1) of the first floor (121) may be placed in the same position as the inner column (P2) of the second floor (122), and the outer column (Q1) of the first floor (121) may be placed in the same position as the outer column (Q2) of the second floor.

[0086] Accordingly, even if one module (12) has a structure that is rotated and displaced by floor, the inner columns (1213) and outer columns (1214) of each floor can be interconnected with the columns of adjacent floors. Additionally, the inner columns (1213) and outer columns (1214) of each of the multiple modules (12) can be interconnected.

[0087] In addition, the thickness of the slab constituting the inner portion (1211) and the outer portion (1212) can be provided to be 300 mm or more.

[0088] As described above, in one embodiment, the multi-unit dwelling (1) has an inner column (1213) and an outer column (1214) rotated at an angle ( Structural stability can be maintained by arranging them in an alternating manner according to the ) and utilizing the inner column (1213) and outer column (1214) to reduce the deflection of the slab.

[0089] In addition, slab deflection can be controlled without using special construction methods such as post-tensioning, thereby reducing construction costs and efficiently ensuring structural stability in terms of construction methods.

[0090] Additionally, the module (12) may include an integrated facility space that is vertically arranged across the entire floor. The integrated facility space may be provided in multiple numbers. Each integrated facility space may be arranged adjacent to an inner column.

[0091] The integrated facility space may include, for example, piping installed on each floor.

[0092] Referring to FIG. 7, the first layer (121) may include, for example, a plurality of pipes (1215) arranged adjacent to a plurality of inner columns (1213).

[0093] Multiple pipes on the nth floor and multiple pipes on the n+1th floor can each be placed at the same location in the vertical direction. Accordingly, pipes on adjacent floors can be connected to each other. The pipes placed on the nth floor can each be placed in areas that perform different functions.

[0094] Referring to FIG. 8(a), in the first layer (121), one pipe (W11) among a plurality of pipes (1215) may be placed in an unused area (X), another pipe (W12) may be placed in the first room (R1), yet another pipe (W13) may be placed in the second room (R2), and yet another pipe (W14) may be placed in the third room (R3). At this time, the pipe (W11) placed in the unused area may be a dummy.

[0095] Additionally, with reference to FIG. 8(b), the second layer (122) may have one pipe (W21) among a plurality of pipes (1225) placed in the third room (R3), another pipe (W22) placed in the unused area (X), another pipe (W23) placed in the first room (R1), and another pipe (W24) placed in the second room (R2). At this time, the pipe (W22) placed in the unused area may be a dummy.

[0096] At this time, the pipe (W11) of the first floor (121) is positioned at the same location as the pipe (W21) of the second floor (122) and is connected to each other, the pipe (W12) of the first floor (121) is positioned at the same location as the pipe (W22) of the second floor (122) and is connected to each other, the pipe (W13) of the first floor (121) is positioned at the same location as the pipe (W23) of the second floor (122) and is connected to each other, and the pipe (W14) of the first floor (121) is positioned at the same location as the pipe (W24) of the second floor (122) and is connected to each other.

[0097] Referring to FIG. 9, the piping (1215) of the first floor (121), the piping (1225) of the second floor (122), the piping (1235) of the third floor (123), and the piping (1245) of the fourth floor (124) are each positioned in the same vertical direction and can be connected to each other. Ultimately, the piping (1215, 1225, 1235, 1245) of each floor can form a single integrated facility space connected to each other, and even if different water spaces are arranged for each floor according to rotational displacement, piping processing can be facilitated.

[0099] As described above, the multi-unit dwelling (1) according to one embodiment has a terrace for each household while maintaining the same size of the living space, so that all households on all floors can have the same floor plan configuration.

[0100] According to one embodiment of the multi-unit housing (1), there is an effect of securing diversity in the exterior and originality in the facade design.

[0101] According to one embodiment of the multi-unit dwelling (1), the outer periphery (1212) of each floor is rotated and displaced at a certain angle to form different planar configurations, thereby forming a unique exterior and providing a pleasant living space.

[0102] According to one embodiment of the multi-unit housing (1), it can have a flexible design structure that provides a differentiated living space for each household and can reflect the various needs of the residents.

[0103] According to the multi-unit housing (1) according to one embodiment, the facility space and functional configuration can be varied by floor while maintaining structural stability, thereby providing an optimized living environment for each household.
