[0005] [Patent Document 1] Japanese Patent Publication No. 2001-254413 [Patent Document 2] Patent No. 6596305 [Patent Document 3] Patent No. 7194568 [Overview of the project] [Problems that the invention aims to solve]

[0006] The problem that this invention aims to solve is to provide a piping system for apartment buildings that has a common corridor and dwelling units on each floor, which can efficiently arrange equipment piping and reduce the length of the equipment piping. [Means for solving the problem]

[0007] To solve the above problems, the present invention employs the following means. In other words, the equipment piping system for a multi-unit dwelling according to the present invention is an equipment piping system for a multi-unit dwelling having a common corridor and dwelling units on each floor, comprising a common corridor vertical shaft located in the common corridor and a dwelling unit vertical shaft located inside the dwelling unit, wherein in each of the dwelling units, the equipment piping is arranged to extend into the dwelling unit from either or both of the common corridor vertical shaft and the dwelling unit vertical shaft located inside the dwelling unit. With the above configuration, in an apartment building with a common corridor and dwelling units on each floor, there is a common corridor vertical shaft located in the common corridor and a dwelling unit vertical shaft located inside the dwelling unit. In this situation, in each dwelling unit, the equipment piping is arranged to extend into the dwelling unit from either the common corridor vertical shaft or the dwelling unit vertical shaft located inside the dwelling unit, or both. In other words, in each dwelling unit, each piece of equipment can be connected to the common corridor vertical shaft or the dwelling unit vertical shaft that best and efficiently arranges the equipment piping, depending on the location of the equipment within the dwelling unit. This makes it possible to efficiently arrange equipment piping and reduce the length of equipment piping in an apartment building with a common corridor and dwelling units on each floor.

[0008] In one embodiment of the present invention, the equipment piping system for an apartment building of the present invention is such that in one of the vertical shafts of the common corridor, the lower vertical shaft located below a specific floor and the upper vertical shaft located above it have different positions when viewed from above, and the lower vertical shaft extends from below to below the floor slab of the specific floor and is connected to the upper vertical shaft below the floor slab via connecting lateral piping. For example, in apartment buildings, the layout of units may be changed between the upper and lower floors, such as when the goal is to increase the area of ​​the units on the upper floors. When the layout of units changes between the upper and lower floors of an apartment building, the location of the common corridor may also change. In such cases, it can be difficult to install the common corridor vertical shaft so that it penetrates both the upper and lower floors of the apartment building vertically at the same position when viewed from above. In contrast, with the above configuration, the floor on which the layout of the dwelling unit is to be changed is designated as the specific floor, and a configuration is realized in which the upper common corridor vertical shaft, located above the floor slab of the specific floor, and the lower common corridor vertical shaft, located below the floor slab of the specific floor, are in different positions when viewed from above. As a result, the layout of the dwelling unit can be changed above and below the specific floor of the apartment building without being significantly affected by the arrangement of the common corridor vertical shaft. Therefore, it is possible to increase the degree of freedom in the layout of the dwelling unit.

[0009] In one aspect of the present invention, the equipment piping system for a multi-unit dwelling of the present invention comprises, in the multi-unit dwelling, a floor slab comprising a dwelling unit floor slab provided in the dwelling unit, and a corridor floor slab provided in the common corridor and connected to the dwelling unit floor slab, wherein the corridor floor slab comprises a low-floor section constructed on the dwelling unit side and a high-floor section connected to the low-floor section by a wall section extending upward from the low-floor section, and a double floor is formed by providing flooring material on the low-floor section and the dwelling unit floor slab, and the equipment piping is directly introduced from the vertical shaft of the dwelling unit into the interior of the double floor of the dwelling unit floor slab. As a result, the equipment piping is routed from the vertical shaft of the dwelling unit to the dwelling unit. When the dwelling unit and the vertical shaft of the common corridor are separated by the common corridor, the equipment piping is routed from the vertical shaft of the common corridor, passing under the raised floor section, through the wall section, and into the double floor of the low floor section and the dwelling unit floor slab, thereby being routed to the dwelling unit. When the dwelling unit and the vertical shaft of the common corridor are adjacent, the equipment piping is routed directly from the vertical shaft of the common corridor into the double floor of the dwelling unit floor slab, thereby being routed to the dwelling unit. With this configuration, a double floor is provided within the dwelling unit, and in all cases—whether the equipment piping is routed from a vertical shaft within the dwelling unit to the dwelling unit, from a vertical shaft in a common corridor spaced apart from the dwelling unit to the dwelling unit, or from a vertical shaft in a common corridor adjacent to the dwelling unit to the dwelling unit—the equipment piping is introduced and routed inside the double floor of the dwelling unit's floor slab, allowing for a high degree of flexibility in the layout of the equipment piping. [Effects of the Invention]

[0010] According to the present invention, in an apartment building equipped with a common corridor and dwelling units on each floor, it is possible to efficiently arrange equipment piping and reduce the length of the equipment piping. [Brief explanation of the drawing]

The vertical shafts 52C and 52D of the dwelling unit are located within dwelling unit 30G. The vertical shaft 52C of the dwelling unit is located on balcony 39 within dwelling unit 30G.

[0018] Figure 5 is a cross-sectional view showing the vertical shafts within the dwelling units on each floor. Figure 5 is mainly a cross-sectional view of the vertical shaft 52A, as seen from arrow II in Figures 2 to 4, but similar diagrams can be used to explain the vertical shafts 52B to 52C. Figure 6 is a cross-sectional view showing the common corridor vertical shafts installed in the common corridors on each floor. Figure 6 is mainly a cross-sectional view of the common corridor vertical shaft 51A as seen by arrow II-II in Figures 2 to 4, but a similar diagram can be used to explain the common corridor vertical shaft 51B. Each floor's floor slab 7 comprises a dwelling unit floor slab 35 provided in the dwelling unit 30, and a corridor floor slab 22 (see Figure 6) provided in the common corridor 20, to which the dwelling unit floor slab 35 is connected. Within each dwelling unit 30, a double floor 37 is formed, comprising a dwelling unit floor slab 35 and a flooring material 36 supported above the dwelling unit floor slab 35 at intervals by support members (not shown).

[0019] As shown in Figure 6, the corridor floor slab 22 comprises a low-floor section 23, a high-floor section 24, and a wall section 25. The low-floor section 23 is constructed in the common corridor 20, on the side of the entrance door 34 of the dwelling unit 30. In this embodiment, the low-floor section 23 is provided in the portion of the alcove 38 formed in front of the entrance door 34 of each dwelling unit 30. Above the low-floor section 23, a flooring material 28 is provided, supported by a support member (not shown). On the dwelling unit 30 side of the common corridor 20, a double floor 26 is formed, consisting of the low-floor section 23 and the flooring material 28 above it.

[0020] The raised floor section 24 is located in the common corridor 20 on the side opposite the entrance door 34 of the dwelling unit 30. The raised floor section 24 is constructed at a higher position than the low floor section 23. The upper surface 24t of the raised floor section 24 is formed to be a predetermined dimension higher than the upper surface 23t of the low floor section 23. The raised floor section 24 is equipped with a raised floor section flooring material 27 provided on the raised floor section 24. The raised floor section flooring material 27 is formed integrally with the flooring material 28 of the low floor section 23. The floor surface of the common corridor 20 is formed by the flooring material 28 of the low floor section 23 and the raised floor section flooring material 27 of the raised floor section 24. The wall section 25 extends vertically and connects the low-floor section 23 and the high-floor section 24 vertically at the boundary between them. In areas other than the alcove 38, the wall section 25 is formed continuously on the lower side of the inner wall 32. The height of the wall section 25, that is, the length from the upper surface of the low-floor section 23 to the lower surface of the high-floor section 24, is formed to be greater than the diameter of the dwelling unit piping 130, which will be described later. In this way, the elevated section 24 is connected to the low-floor section 23 by a wall section 25 that extends upward from the low-floor section 23.

[0021] Apartment building 1 is equipped with utility piping 100. The utility piping 100 includes water pipes to supply tap water, gas pipes to supply gas, electrical wiring to supply electricity, communication lines such as optical fibers and telephone lines, and drainage pipes to discharge sewage from each of the facilities not shown in each apartment building 30. The equipment piping 100 includes a main vertical pipe 110 and dwelling unit piping 130. As shown in Figures 1 to 4, the main vertical piping 110 is inserted into the common corridor vertical shafts 51A and 51B, and the dwelling unit vertical shafts 52A to 52D, respectively. The dwelling unit piping 130 branches off from the main vertical piping 110 and is routed into each dwelling unit 30. In each dwelling unit 30, the dwelling unit piping 130 of the equipment piping 100 is routed to extend into the dwelling unit 30 from either or both of the common corridor vertical shafts 51A and 51B, and the dwelling unit vertical shafts 52A to 52D located inside the dwelling unit 30. In this embodiment, in each dwelling unit 30, the equipment piping 100 (dwelling unit piping 130) is routed to extend into the dwelling unit 30 from both the common corridor vertical shafts 51A and 51B located immediately adjacent to the dwelling unit 30, and the dwelling unit vertical shafts 52A to 52D. In each of the dwelling units 30, the equipment piping 100 (dwelling unit piping 130) may be installed to extend to the dwelling unit 30 from either the common corridor vertical shafts 51A and 51B located immediately adjacent to the dwelling unit 30, or from the dwelling unit vertical shafts 52A to 52D.

[0022] As shown in Figures 2 to 5, in each of the dwelling units 30A to 30D on the 1st floor F1 to the 7th floor F7, and in each of the dwelling units 30E to 30G on the 8th floor F8 to the 10th floor F10, the equipment piping 100 (dwelling unit piping 130) is directly introduced from the dwelling unit vertical shafts 52A to 52D located inside each unit into the interior of the double floor 37 of the dwelling unit floor slab 35, that is, into the space between the dwelling unit floor slab 35 and the flooring material 36, thereby providing the equipment piping 100 (dwelling unit piping 130) from the dwelling unit vertical shafts 52A to 52D to the dwelling unit 30.

[0023] As shown in Figures 2 to 4 and Figure 6, in the alcove 38 portion of dwelling units 30B and 30C on the 1st floor F1 to the 7th floor F7, dwelling unit 30F on the 8th floor F8 to the 10th floor F10, and dwelling unit 30G, the dwelling unit 30 (the alcove 38 portion and entrance door 34 portion) and the common corridor vertical shafts 51A and 51B are separated via the common corridor 20. In this case, the equipment piping 100 (dwelling unit piping 130) is introduced to the dwelling unit 30 by passing from the common corridor vertical shafts 51A and 51B, particularly as shown to the right of the common corridor vertical shafts 51A and 51B in Figure 6, passing under the elevated section 24, penetrating the wall section 25, and entering the interior of the double floor 26 of the low-floor section 23 (between the low-floor section 23 and the flooring material 28), and the interior of the double floor 37 of the dwelling unit floor slab 35 (between the dwelling unit floor slab 35 and the flooring material 36).

[0024] Furthermore, in dwelling units 30A and 30D on the 1st floor (F1) to the 7th floor (F7), dwelling units 30E and 30G on the 8th floor (F8) to the 10th floor (F10), dwelling unit 30 is adjacent to the common corridor vertical shafts 51A and 51B. In this case, the equipment piping 100 (dwelling unit piping 130) is installed to the dwelling unit 30 by being directly introduced from the common corridor vertical shafts 51A and 51B into the interior of the double floor 37 of the dwelling unit floor slab 35, that is, between the dwelling unit floor slab 35 and the flooring material 36, as shown particularly to the left of the common corridor vertical shafts 51A and 51B in Figure 6.

[0025] Figure 7 is a longitudinal cross-sectional view showing the lower common corridor vertical shaft located below a specific floor and the upper common corridor vertical shaft located above it. Figure 7 is a schematic longitudinal cross-sectional view of the area near the point indicated by arrow A in Figure 3. As shown in Figure 7, among the multiple common corridor vertical shafts 51A and 51B, one common corridor vertical shaft 51B has different positions in a plan view between the lower common corridor vertical shaft 51Ba, located below the specific floor F8 on the 8th floor, and the upper common corridor vertical shaft 51Bb, located above it. The lower common corridor vertical shaft 51Ba extends from below to below the floor slab 7 on the specific floor F8 on the 8th floor, and below the floor slab 7, it is connected to the lower end of the upper common corridor vertical shaft 51Bb via connecting horizontal pipe 140.

[0026] According to the equipment piping system S for the apartment building 1 described above, the equipment piping system S for the apartment building 1 is an equipment piping system S for an apartment building 1 having a common corridor 20 and dwelling units 30 on each floor, comprising common corridor vertical shafts 51A, 51B located in the common corridor 20 and dwelling unit vertical shafts 52A to 52D located inside the dwelling units 30, and in each of the dwelling units 30, the equipment piping 100 is arranged to extend into the dwelling unit 30 from either one or both of the common corridor vertical shafts 51A, 51B and the dwelling unit vertical shafts 52A to 52D located inside the dwelling units 30. According to the above configuration, in an apartment building 1 having a common corridor 20 and dwelling units 30 on each floor, there are common corridor vertical shafts 51A and 51B located in the common corridor 20, and dwelling unit vertical shafts 52A to 52D located inside the dwelling units 30. In this situation, in each dwelling unit 30, the equipment piping 100 is arranged to extend into the dwelling unit 30 from either or both of the common corridor vertical shafts 51A and 51B and the dwelling unit vertical shafts 52A to 52D located inside the dwelling unit 30. In other words, in each dwelling unit 30, each piece of equipment can be connected to the common corridor vertical shafts 51A and 51B and the dwelling unit vertical shafts 52A to 52D in which the equipment piping 100 is arranged most appropriately and efficiently, depending on the location of the equipment within the dwelling unit 30. This makes it possible to efficiently arrange the equipment piping 100 and reduce the length of the equipment piping 100 in an apartment building 1 that has a common corridor 20 and dwelling units 30 on each floor.

[0027] In particular, when the equipment piping 100 for the dwelling unit 30 is installed so as to extend from the common corridor vertical shafts 51A and 51B, the distance between the common corridor vertical shafts 51A and 51B and the dwelling unit 30 is reduced compared to when the common corridor vertical shafts 51A and 51B are installed in a limited location such as the core section C where elevators EV etc. are installed, and this may reduce the length of the equipment piping 100. This suppresses the need for the equipment piping 100 to be excessively long.

[0028] Furthermore, in the equipment piping system S of the apartment building 1, in one of the common corridor vertical shafts 51A and 51B, the lower common corridor vertical shaft 51Ba, located below a specific floor F8, and the upper common corridor vertical shaft 51Bb, located above, have different positions when viewed from above. The lower common corridor vertical shaft 51Ba extends from below to below the floor slab 7 of the specific floor F8, and below the floor slab 7, it is connected to the upper common corridor vertical shaft 51Bb via connecting horizontal pipe 140. For example, the layout of dwelling units 30 may be changed between the upper and lower parts of apartment building 1, such as when it is desired to increase the area of ​​dwelling unit 30 on the upper floors of apartment building 1. In such cases, it may be difficult to install the common corridor vertical shaft 51B so that it penetrates both the upper and lower parts of apartment building 1 vertically at the same position when viewed from above. In contrast, with the above configuration, the floor on which the layout of the dwelling unit 30 is to be changed is designated as the specific floor F8, and a configuration is realized in which the upper common corridor vertical shaft 51Bb, which is located above the floor slab 7 of the specific floor F8, and the lower common corridor vertical shaft 51Ba, which is located below the floor slab 7 of the specific floor F8, are in different positions when viewed from above. As a result, the layout of the dwelling unit 30 can be changed above and below the specific floor F8 of the apartment building 1 without being greatly affected by the arrangement of the common corridor vertical shaft 51B. Therefore, it is possible to increase the degree of freedom in the layout of the dwelling unit 30.

[0029] Furthermore, the equipment piping system S of the apartment building 1 is provided with multiple common corridor vertical shafts 51A and 51B, and in each of the dwelling units 30, the equipment piping 100 is arranged to extend to the dwelling unit 30 from either or both of the common corridor vertical shafts 51A and 51B located immediately adjacent to the dwelling unit 30, and the dwelling unit vertical shafts 52A to 52D. With this configuration, when it is necessary to connect equipment to one of the multiple common corridor vertical shafts 51A and 51B in each of the dwelling units 30, using the nearest common corridor vertical shaft 51A or 51B more effectively suppresses the need to lengthen the equipment piping 100.

[0030] Furthermore, in the apartment building 1, the floor slab 7 comprises an apartment floor slab 35 provided in the apartment 30, and a corridor floor slab 22 provided in the common corridor 20 to which the apartment floor slab 35 is connected. The corridor floor slab 22 comprises a low floor section 23 constructed on the apartment 30 side, and a high floor section 24 connected to the low floor section 23 by a wall section 25 extending above the low floor section 23. Flooring materials 28 and 36 are provided on the low floor section 23 and the apartment floor slab 35 to form double floors 26 and 37. Equipment piping 100 is directly introduced from the apartment vertical shafts 52A to 52D into the interior of the double floor 37 of the apartment floor slab 35, Equipment piping 100 is installed from 52D to dwelling unit 30. When dwelling unit 30 and common corridor vertical shafts 51A and 51B are separated by the common corridor 20, the equipment piping 100 is installed to dwelling unit 30 by passing under the elevated section 24 from the common corridor vertical shafts 51A and 51B, penetrating the wall section 25, and being introduced into the double floors 26 and 37 of the low section 23 and dwelling unit floor slab 35. When dwelling unit 30 and common corridor vertical shafts 51A and 51B are adjacent, the equipment piping 100 is installed to dwelling unit 30 by being directly introduced from the common corridor vertical shafts 51A and 51B into the double floors 37 of the dwelling unit floor slab 35. With this configuration, a double floor 37 of the dwelling unit floor slab 35 is provided within the dwelling unit 30. In cases where equipment piping 100 is installed from the dwelling unit vertical shafts 52A to 52D to the dwelling unit 30, where equipment piping 100 is installed from the common corridor vertical shafts 51A and 51B located spaced apart from the dwelling unit 30, or where equipment piping 100 is installed from the common corridor vertical shafts 51A and 51B adjacent to the dwelling unit 30, the equipment piping 100 is introduced and installed inside the double floor 37 of the dwelling unit floor slab 35, allowing for a high degree of flexibility in the layout of the equipment piping 100.

[0031] Thus, in this embodiment, the layout of the equipment piping 100 can be designed with a high degree of freedom. Therefore, when planning the equipment piping 100, the influence of limitations such as the floor plan of each floor of the apartment building 1 (layout of the dwelling units 30) and floor height is reduced. Consequently, the equipment piping 100 can be planned more freely.

[0032] (Modified version of the embodiment) It should be noted that the equipment piping system for apartment buildings of the present invention is not limited to the embodiments described above with reference to the drawings, and various modifications are conceivable within its technical scope. For example, Figure 8 is a schematic longitudinal cross-sectional view showing the installation configuration of equipment piping in an equipment piping system for an apartment building according to a modified example of the above embodiment. In this modified example, the equipment piping system SA of the apartment building 1 has a different piping configuration for the equipment piping 300 compared to the equipment piping 100 in the above embodiment. The equipment piping 300 includes a main vertical pipe 310, a secondary vertical pipe 340, and dwelling unit piping 330, as well as dwelling unit piping 350 for other floors. The main vertical pipe 310 is installed by penetrating the common corridor vertical shaft 51C from floor to floor. Unlike the above embodiment, in some of the multiple floors, the dwelling unit piping 330 installed in each dwelling unit 30 on that floor is connected to the main vertical piping 310 and is located below the elevated section 24 of the common corridor 20. On the multi-story building, except for some floors, a secondary vertical pipe 340 is connected, branching off from the dwelling unit piping 330 installed on some floors and extending vertically to the other floors below. The secondary vertical pipe 340 is installed so as to extend vertically from the dwelling unit piping 330 on some floors within the area where meter boxes, etc., are installed, and then reach the lower floor. The lower end of the secondary vertical pipe 340 is connected to the dwelling unit piping 350 of the other floor, which is connected to the dwelling unit 30 on the floor below. The dwelling unit piping 350 is installed from above the dwelling unit floor slab 35 of the dwelling unit 30 on the floor below into the double floor 26 of the low floor section 23. The dwelling unit piping 350 of the other floor is connected to the secondary vertical pipe 340 within the double floor 26.

[0033] In addition to the above, it is possible to select or replace the configurations listed in the above embodiments, or to change them to other configurations as appropriate, as long as it does not deviate from the spirit of the present invention. [Explanation of symbols]
