Description

The present invention relates to a floor slab structure for collective housing.

2. Description of the Related Art In collective housing, a plurality of dwelling units provided on each floor are provided with facility piping for supplying and discharging water, sewage, electricity, gas, and the like. Such equipment pipes are provided by branching pipes connected to each dwelling unit from a main vertical pipe provided over the upper and lower floors. For example, in Patent Document 1, a vertical piping space that penetrates each floor along a plurality of dwelling units arranged on the upper and lower floors is provided, and the floor slab of each dwelling unit is provided with a pit forming portion that becomes a groove-shaped piping pit on the upper surface. A configuration is disclosed in which the equipment piping is provided in the piping pit.
In such a collective housing, when each floor has a common corridor and a dwelling unit facing the common corridor, the equipment piping is arranged along the common corridor by branching from the main vertical pipe and the main vertical pipe. It may be configured to have a horizontal pipe that connects the horizontal pipe and a dwelling unit pipe that is connected to each dwelling unit from the horizontal pipe.
In such a case, if horizontal pipes are provided above the floor slab of the common corridor, for example, if the horizontal pipes are of a type that produces noise such as a drain pipe, the sound will not reach the dwelling unit facing the common area. Therefore, horizontal piping can become a noise source.

In order to reduce such noise caused by facility piping, horizontal piping is sometimes provided under the floor slab in common areas. For example, in Patent Document 2, a main vertical pipe provided through the upper and lower floors, an in-dwelling lead-in pipe provided in a dwelling unit on each floor, and a horizontal pipe connecting the main vertical pipe and the in-dwelling lead-in pipe and a pipe, wherein the horizontal pipe is provided under the floor slab of the common area. In this configuration, a double floor is formed on the floor slab on the common area side of each dwelling unit. The horizontal piping that is drawn horizontally to the vicinity of the dwelling unit penetrates the floor slab obliquely upward in the vicinity of the dwelling unit and is pulled out inside the double floor.
In the configuration disclosed in Patent Document 2, for example, when the building is renovated and the floor plan of the dwelling unit is changed, and accordingly the piping route needs to be changed, the piping is moved to the top of the floor slab. Only a limited area of the double-floor part of the pulled-out dwelling unit needs to accommodate this. Therefore, flexibility in changing the piping route is low, and it is not easy to change the piping route.
Further, in Patent Document 3, the corridor floor slab of the common corridor is constructed by providing a stepped portion so as to be positioned above the end of the common corridor side of the living floor slab, and the drainage path on the living floor slab is An arrangement is disclosed that is taken out below the hallway floor slab in the vicinity of the .
Even in the configuration disclosed in Patent Document 3, when the floor plan of the dwelling unit is changed and it is necessary to change the piping route accordingly, only the limited area of the living floor slab portion of the dwelling unit This needs to be addressed. Therefore, flexibility in changing the piping route is low, and it is not easy to change the piping route.

The problem to be solved by the present invention is to provide a floor slab structure for an apartment complex that suppresses noise from equipment pipes to a dwelling unit and allows relatively easy change of the piping route of the equipment pipes when the dwelling units are renewed. is.

In order to solve the above problems, the present invention employs the following means.
That is, the floor slab structure of an apartment complex of the present invention is a floor slab structure of an apartment complex comprising a common corridor and a dwelling unit facing the common corridor on each floor, wherein the dwelling unit floor slab provided in the dwelling unit; A hallway floor slab provided in the common hallway to which the dwelling unit floor slab is connected, wherein the hallway floor slab includes a low floor section constructed on the dwelling unit side and an upper floor section above the low floor section. a high-floor portion connected to the low-floor portion by an extending wall portion, wherein floor materials are provided on the low-floor portion to form a double floor; It is characterized in that it is arranged from above the floor slab of the dwelling unit to below the high floor portion through the double floor of the low floor portion and through the wall portion.
The low floor part that forms the corridor floor slab is formed only on one side of the common corridor if there are dwelling units on only one side of the common corridor, and in the center part of the common corridor if there are dwelling units on both sides of the common corridor. There is a high floor on one side and a low floor connected to the wall on one or both sides of the common corridor.
According to such a configuration, a double floor made up of a low-floor portion and flooring material provided on the low-floor portion is formed on the dwelling unit side of the shared corridor. In this way, by forming a double floor in the common corridor part, the equipment piping is not only on the floor slab of the dwelling unit inside the dwelling unit, but also in the double floor part on the dwelling unit side of the common corridor. placed above. Therefore, when changing the route of the equipment piping in the dwelling unit, it is possible to adjust the route of the equipment piping not only in the dwelling unit but also in the double floor portion of the common corridor. Therefore, when renewing a dwelling unit, the flexibility of changing the route of the equipment piping is improved, and the route change can be handled more easily.
Further, the hallway floor slab of the common hallway has a certain height difference between the low floor portion and the high floor portion so that the wall portion is formed so as to extend in the vertical direction. In other words, in the shared corridor, when changing the route of equipment piping in the space above the low floor, there is room to change the route not only in the horizontal direction but also in the vertical direction. Therefore, the flexibility of changing the route of the facility piping is further improved.
In addition, in the common corridor, the equipment pipes pass through the wall provided between the low floor and the high floor and are placed below the high floor on the opposite side of the low floor from the residential units. is set. As a result, the sound caused by the pipes placed below the raised floor is effectively cut off by the raised floor and wall of the corridor floor slab, so that high soundproofing performance can be achieved in the living space of the dwelling unit. .
In this way, it is possible to suppress the noise from the equipment pipes to the dwelling unit, and to relatively easily change the piping route of the equipment pipes at the time of renewal of the dwelling unit.

In one aspect of the present invention, the height of the upper surface of the floor slab for the dwelling unit and the height of the upper surface of the low floor portion are substantially the same.
According to such a configuration, by making the upper surface height of the floor slab of the dwelling unit substantially the same as the upper surface height of the low floor part, for example, when the equipment pipe is a drain pipe, the flow from the dwelling unit side to the common corridor side It is easy to ensure an appropriate water gradient for the equipment piping, and excellent drainage performance can be easily ensured. Here, each upper surface height of the floor slab of the dwelling unit and the low floor portion is substantially the same, which means that the equipment pipes are installed on the upper surface of each slab from the floor slab of the dwelling unit to the low floor portion with a constant slope via the height adjustment material. A difference in the top surface height of the slab that can be installed with Specifically, the floor slab of the dwelling unit and the low floor part are substantially the same as long as the height of each upper surface is within 5 cm.
Moreover, since the height of the upper surface of the floor slab for the dwelling unit and the height of the upper surface of the low floor portion are substantially the same, construction of the floor slab can be easily performed.

In one aspect of the present invention, the facility pipe includes a horizontal pipe provided along the common corridor under the high floor portion, and a dwelling unit pipe that connects the horizontal pipe and the dwelling unit. The pipe for the dwelling unit is arranged from above the floor slab for the dwelling unit, through the double floor of the low floor portion, through the wall portion, and to the lower portion of the high floor portion.
According to such a configuration, the pipes for the dwelling unit are arranged not only on the floor slab of the dwelling unit in the dwelling unit, but also on the double floor portion of the common corridor on the dwelling unit side on the low floor portion. Therefore, when changing the route of equipment piping in a dwelling unit, it is possible to adjust the route of the dwelling unit piping not only in the dwelling unit but also in the double floor portion of the common corridor.
In addition, the dwelling unit pipe can penetrate through the wall portion provided between the low floor portion and the high floor portion, and can be connected to the horizontal pipe provided along the common corridor below the high floor portion. As a result, the sound caused by the horizontal pipes placed under the raised floor is effectively blocked by the raised floor and walls of the corridor floor slab, so the living space in the dwelling unit has high soundproofing performance. realizable.
In addition, in the low-floor area, the residential unit piping is laid above the floor slab of the corridor. In this case, even if the pipe makes a sound, it is only when the dwelling unit performs an action using the pipe, and in many cases, the sound produced by the action itself is louder than the sound produced by the pipe. That is, even if a dwelling unit pipe generates a sound, this sound is unlikely to become noise in a dwelling unit using the dwelling unit pipe located in the vicinity thereof.
Furthermore, since the horizontal piping is installed under the elevated floor section separated by the wall and the elevated floor section, that is, on the ceiling of the floor located below the elevated floor section, it is difficult to bring in items during construction of the building. It is possible to suppress obstacles caused by horizontal pipes during flow lines and work.

According to the present invention, it is possible to provide a floor slab structure for an apartment complex that suppresses noise from equipment pipes to a dwelling unit and allows relatively easy change of the piping route of the equipment pipes when the dwelling units are renewed. .

It becomes possible.
In addition, the dwelling unit pipe 130 penetrates the wall portion 25 provided between the low floor portion 23 and the high floor portion 24, and is provided below the high floor portion 24 along the common corridor 20. Horizontal pipe 120 can be connected to As a result, the sound caused by the horizontal piping 120 arranged below the raised floor portion 24 is effectively blocked by the raised floor portion 24 and the wall portion 25 of the corridor floor slab 22, so that the living space in the dwelling unit 30 can achieve high soundproofing performance.
In addition, in the low floor part 23, the dwelling unit piping 130 is piped above the corridor floor slab 22, but this dwelling unit piping 130 is basically dedicated to the dwelling unit 30 corresponding to the dwelling unit piping 130. There are many. In this case, even if the pipe makes a sound, it is only when the dwelling unit 30 performs an action using the pipe, and in many cases, the sound emitted by the action itself is louder than the sound of the pipe. That is, even if the dwelling unit piping 130 produces a sound, the sound is unlikely to become noise in the dwelling unit 30 using the dwelling unit piping 130 located in the vicinity thereof.
Furthermore, since the horizontal piping 120 is installed below the raised floor section 24 separated by the wall section 25 and the raised floor section 24, that is, on the ceiling of the floor F located below the raised floor section 24, the building construction It is possible to prevent the lateral pipe 120 from becoming an obstacle during the carrying-in flow line of articles and the like during work.

Further, the corridor floor slab 22 is provided with a wall part 25 which functions like a beam material continuously in the direction in which the common corridor 20 extends, between the low floor part 23 and the high floor part 24 . Thereby, the rigidity of the corridor floor slab 22 can be increased without increasing its thickness.
In addition, by providing a horizontal piping 120 on the lower side of the high floor section 24 and connecting the dwelling unit piping 130 to the horizontal piping 120 on the lower side of the high floor section 24, in the high floor section 24, the piping is installed on the upper side of the high floor section 24. There is no need to pass through, and there is no need to have a double floor structure. In addition, since the dwelling unit piping 130 is arranged on the low floor section 23, there is no need to arrange the horizontal piping 120 under the low floor section 23. can be made smaller. In this way, since it is possible to realize rational piping as a whole, the piping space in the common corridor 20 can be reduced. Therefore, the floor height can be lowered.
In addition, since the main vertical pipe 110 is provided in the shared equipment space 10 and is installed away from the dwelling unit 30, the influence of noise caused by the main vertical pipe 110 can be reduced.

(First modification of the embodiment)
It should be noted that the floor slab structure for collective housing according to the present invention is not limited to the above-described embodiments described with reference to the drawings, and various modifications are conceivable within the technical scope thereof.
For example, in the above-described embodiment, the floor slab 35 of the dwelling unit and the low floor portion 23 are integrally continuous, but the configuration is not limited to this.
FIG. 4 is a cross-sectional view showing a floor slab structure of a collective housing according to a first modified example of the embodiment of the present invention.
As shown in FIG. 4, in the common corridor 20, when the beam 70 is provided on the side of the dwelling unit 30, the beam 70 may form the whole or part of the low floor section 23B. In this case, the beam 70 extends in the direction in which the common corridor 20 continues on the dwelling unit 30 side in the common corridor 20 . Dwelling unit floor slab 35 is joined to beam 70 . The height of the upper surface 35t of the floor slab 35 of the dwelling unit and the height of the upper surface 70t of the beam 70 forming the low floor portion 23B are substantially the same. A floor material 28 is provided above the beams 70, and the upper surface 70t of the beams 70 and the floor material 28 form a double floor 26B.
As in the above-described embodiment, the high floor section 24 is constructed at a position higher than the upper surfaces 70t of the beams 70 that constitute the low floor section 23B. The wall portion 25 extends in the vertical direction and connects the upper surface 70t of the beam 70 constituting the low floor portion 23B and the high floor portion 24 .
The dwelling unit pipe 130 is arranged from above the dwelling unit floor slab 35 to below the high floor portion 24 through the wall portion 25 via the double floor 26B on the low floor portion 23B.
Even in such a configuration, as in the above-described embodiment, it is possible to suppress noise from the equipment pipe 100 to the dwelling unit 30, and to relatively easily change the piping route of the equipment pipe 100 when the dwelling unit 30 is renewed. .

(Second modification of the embodiment)
Next, with reference to FIG. 5, a second modified example of the floor slab structure of the collective housing shown as the above embodiment will be described. FIG. 5 is a schematic vertical cross-sectional view showing an installation mode of equipment pipes in the floor slab structure of the collective housing according to the second modified example. In the housing complex 1 according to the second modified example, the piping form of the facility piping 300 is different from the facility piping 100 in the above-described embodiment.

The facility piping 300 includes a main vertical piping 310 , a horizontal piping 320 , a secondary vertical piping 340 , a dwelling unit piping 330 , and a dwelling unit piping 350 on another floor.
The main vertical pipe 310 is provided through the pipe shaft 11 of the shared facility space 10 over the upper and lower floors.
The horizontal piping 320 is provided only on the specific floor FS, unlike the above embodiment. In this modification, one of the two floors F is the specific floor FS, and the floor FD below the specific floor FS is a floor F different from the specific floor FS. The horizontal piping 320 is connected to the main vertical piping 310 on the specific floor FS, and is arranged below the elevated floor section 24 of the shared corridor 20 .
In the specific floor FS, a dwelling unit pipe 330 is connected to the horizontal pipe 320 for each dwelling unit 30 . Dwelling unit pipes 330 are arranged from above the dwelling unit floor slab 35 to below the high floor portion 24 through the double floor 26 of the low floor portion 23 and through the wall portion 25 .
A secondary vertical pipe 340 is connected to the horizontal pipe 320 and extends vertically from the horizontal pipe 320 to a floor F different from the specific floor FS, which is a floor FD below the specific floor FS in this modification. The secondary vertical pipe 340 is led out from the horizontal pipe 320 of the specific floor FS through the wall portion 25 to above the floor slab 35 of the dwelling unit, and extends vertically within the area of the projecting portion 30c where a meter box or the like is provided. After extending in the direction, it is provided so as to reach the double floor 26 of the lower floor FD.
A lower end of the secondary vertical pipe 340 is connected to another floor dwelling unit pipe 350 that is connected to the dwelling unit 30 on the lower floor FD. The other floor dwelling unit pipe 350 is arranged from above the dwelling unit floor slab 35 of the dwelling unit 30 on the lower floor FD into the double floor 26 of the low floor section 23 . The other floor dwelling unit pipe 350 is connected to the secondary vertical pipe 340 within the double floor 26 .

In the collective housing building as described above, the dwelling unit pipes 330 provided in the dwelling units 30 on each floor F, the horizontal pipes 320 connecting the main vertical pipes 310 and the dwelling unit pipes 330 on a specific floor FS, and the horizontal pipes A secondary vertical pipe 340 that extends vertically from 320 to a floor FD different from the specific floor FS and is connected to another floor dwelling unit pipe 350 that is a dwelling unit pipe on a different floor FD. It is provided below the elevated floor section 24 of the shared corridor 20 .
According to the above configuration, since the main vertical pipe 310 is provided in the shared equipment space 10 , the horizontal pipe 320 is required to connect it to the dwelling unit pipe 330 provided in each dwelling unit 30 . Here, since a secondary vertical pipe 340 is provided that extends in the vertical direction from the horizontal pipe 320 to the floor FD different from the specific floor FS and is connected to the other floor dwelling unit pipe 350 on the different floor FD, the horizontal pipe Even if the pipe 320 is provided only on the specific floor FS, the other-floor dwelling unit pipes 350 of the dwelling units 30 other than the specific floor FS can also be connected to the horizontal pipe 320 through the secondary vertical pipe 340 . In this way, by providing the secondary vertical pipes 340 connected to the upper and lower floors near each dwelling unit 30, the installation amount of the horizontal pipes 320 can be reduced, so the material cost and construction cost can be reduced.
In addition, since the main vertical pipe 310 is provided in the common equipment space 10 and is installed away from the dwelling unit 30, the influence of noise caused by the main vertical pipe 310 can be reduced.
Furthermore, regarding the dwelling unit 30 on the floor FD where the horizontal pipe 320 is not installed, it will be connected to the nearest horizontal pipe 320 via the vertically extending auxiliary vertical pipe 340, but the horizontal pipe 320 is Since it is installed for each specific floor FS, it is not necessary to install the secondary vertical pipe 340 so that it straddles many floors F, and therefore, the effect of noise caused by the secondary vertical pipe 340 is reduced. be limited. For the above reasons, it is possible to reduce the influence of equipment noise caused by the pipes on the dwelling units 30 on the upper and lower floors while reducing the installation amount of the horizontal pipes 320 .

Especially in this modification, one of the two floors F is the specific floor FS, the lower floor FD of the specific floor FS is a floor F different from the specific floor FS, and the auxiliary vertical pipe 340 is the specific floor FS. It extends longitudinally from floor FS to floor FD below.
In such a configuration, for example, when the pipe is a water pipe that supplies clean water, only the water used by the residents of the dwelling unit 30 on the lower floor FD, which is not provided with the horizontal pipe 320, is used by this dwelling unit 30. Since the water flows through the secondary vertical pipe 340 to which the other-floor dwelling unit pipe 350 is connected, even if noise is generated from the secondary vertical pipe 340 due to the use of water by the residents of the dwelling unit 30, it is not actually affected. Only the residents of this dwelling unit 30 are using water, and the use of water by other dwelling units 30 is unlikely to become a noise source.
As a result, it is possible to reduce the influence of the noise caused by the water supplied through the pipes on the dwelling units 30 on the upper and lower floors.
It goes without saying that the second modified example has other effects similar to those of the already described embodiment.

The facility piping 400 includes a main vertical piping 410, a horizontal piping 420, a secondary vertical piping 440, a dwelling unit piping 430, and a dwelling unit piping 450 on another floor, as shown in FIG.
The main vertical pipe 410 is provided through the pipe shaft 11 of the shared equipment space 10 over the upper and lower floors.
The horizontal piping 420 is provided only on the specific floor FS. In this modified example, one of the three floors F is the specific floor FS, and the lower floor FD and upper floor FU of the specific floor FS are floors F different from the specific floor FS. The horizontal piping 420 is connected to the main vertical piping 410 on the specific floor FS, and is arranged below the elevated floor section 24 of the shared corridor 20 .
On the specific floor FS, a dwelling unit pipe 430 is connected to a laterally pulled pipe 420 extending to the vicinity of the dwelling unit 30 . The dwelling unit pipe 430 is arranged from above the dwelling unit floor slab 35 , through the double floor 26 of the low floor portion 23 , and through the wall portion 25 to below the high floor portion 24 .
A secondary vertical pipe 440 is connected to the horizontal pipe 420, which extends in the vertical direction from the horizontal pipe 420 to a floor F different from the specific floor FS, in this modification, to the upper floor FU and the lower floor FD of the specific floor FS. ing. The secondary vertical pipe 440 is led from the horizontal pipe 420 of the specific floor FS through the wall portion 25 to above the floor slab 35 of the dwelling unit, and extends vertically within the area of the projecting portion 30c where a meter box or the like is provided. After extending in the direction, it is provided so as to reach the double floor 26 of the lower floor FD and the upper floor FU.
In the lower floor FD, the lower end of the secondary vertical pipe 440 is connected to another floor dwelling unit pipe 450 connected to the dwelling unit 30 of the lower floor FD. In the upper floor FU, the upper end of the secondary vertical pipe 440 is connected to another floor dwelling unit pipe 450 connected to the dwelling unit 30 of the upper floor FU.

It goes without saying that the third modified example has the same effect as the already described embodiment and the second modified example.
In this modified example, the installation amount of horizontal pipes is further reduced. Therefore, the material cost and construction cost can be reduced, and the influence of piping at the time of renewal is further reduced, thereby further improving the renewability.
