Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pipe shaft that houses a soot pipe for supplying water, gas, electricity and the like to each room in a building.
[0002]
[Prior art]
Conventionally, in buildings where multiple living rooms are provided on each floor, such as office buildings and apartment buildings, pipe shafts are provided through the upper and lower floors of this building, and water pipes, drain pipes, Alternatively, soot pipes such as electric lines and gas pipes are passed as main lines in the building.
[0003]
On each floor, branch piping is made from each floor portion of the pipe shaft to each room, and necessary water and electricity are supplied. For example, as shown in FIG. 8, the pipe shaft 1 (shown by a broken line in the figure) is generally provided in a shared portion in a building.
[0004]
For example, as shown in FIG. 8, the water supply pipe 2a and the gas pipe 3a are branched from the water supply pipe 2 and the gas pipe 3 in the pipe shaft 1, respectively, and the branched water supply pipe 2a and the gas pipe 3a are respectively connected. It is drawn into the living room 4 of. At the time of retracting, for example, pipes are run horizontally under the corridor A of the common part, and bent into the living room 4 such as a sink (not shown) or a washstand in the living room 4. Piping is drawn.
[0005]
The drawn water supply pipe 2a and gas pipe 3a are respectively connected to a unit pipe of a water unit, and are used for water supply or water heating in the water unit. A communication wire such as a telephone line and a wire rod 5 through which an electric wire is passed are also passed through the pipe shaft 1, and branch wiring from the wire rod 5 uses the back of the ceiling as shown in FIG. It is drawn into the living room 4.
[0006]
[Problems to be solved by the invention]
Since the pipe shaft of the conventional configuration is provided as a common pipe shaft in common areas such as hallways and stair landings, for example, when a new power source or water is required due to redesign of the living room area, etc. New pipes have to be installed from the pipe shafts of these pipes, and major repairs are required.
[0007]
Therefore, it would be preferable if the shared pipe shaft system of the conventional configuration was modified and a system in which a pipe shaft was provided so as to pass through the living room portion of each floor could be adopted. However, with this method, the pipe shaft installation part bulges out to the indoor side. For example, the layout area of the living room is difficult to adopt a rectangular shape that is easy to use, and the occupied area of the floor is reduced. This method has been difficult to adopt because it is unsatisfactory.
[0008]
An object of the present invention is to allow a pipe shaft to pass through a living room portion without deteriorating the convenience of use of the living room portion.
[0009]
[Means for Solving the Problems]
The present invention is a pipe shaft for piping up and down pipes such as water supply pipes and electric pipes through each floor, and includes a beam provided between columns provided along the inner surface of the outer peripheral wall of the building, and the inner surface of the outer peripheral wall It is characterized by penetrating between the upper and lower floors.
[0010]
The pipe shaft is provided along the upper and lower sides on an inner surface portion of an outer peripheral wall between adjacent windows provided on the outer peripheral wall.
[0011]
A water circulation unit such as a sink is provided under the window adjacent to the pipe shaft, and the water circulation unit is connected to a pipe passing through the pipe shaft.
[0012]
The pipe shaft is configured so as not to protrude indoors from the column.
[0013]
The pipe shaft is formed of a precast concrete plate so as to surround a space through which the steel pipe is passed.
[0014]
The pipe unit adjacent placement method of the water unit of the present invention is a method of arranging the water unit such as a sink, and is provided between the pillars provided along the inner surface of the outer peripheral wall of the building, and provided on the outer peripheral wall. Adjacent to the pipe shaft penetrated to the upper and lower floors along the inner peripheral portion of the outer peripheral wall between the adjacent outer peripheral wall inner portions between the adjacent windows, and the water unit below the window of the window Is provided.
[0015]
The pipe shaft of the present invention is configured to penetrate through the upper and lower floors using a small space between a beam provided between columns provided along the inner surface of the outer peripheral wall of the building and the inner surface of the outer peripheral wall. ing. Such a small space does not protrude to the indoor side from the pillar. Therefore, the pipe shaft of the present invention that effectively uses this small space does not have a concern of deteriorating the usability of the room.
[0016]
Compared to the case where pipe shafts are provided in the common part of each room as in the past, pipe shafts can be provided in the living rooms of each room, so branching from pipes passing through the upper and lower floors to places where piping is required The piping route can be shortened. Accordingly, the branch piping cost can be reduced.
[0017]
Further, when the pipe shaft is configured so as to surround the small space with a precast concrete plate, for example, labor can be significantly saved compared to a case where the pipe shaft is configured with concrete placed on site.
[0018]
In addition, the above small space is a small space that is inevitably formed in the structure when a steel frame is assembled by a conventional method using, for example, a square steel pipe column as a column and an H-shaped steel as a beam. It was not recognized as a spatial object. The inventors of the present invention paid attention for the first time, and their effective use was planned.
[0019]
Furthermore, as described above, the gap generated in the structure between the column and the beam is used as a small space, but the beam passing between the columns is structurally mechanically used so that the small space can be used more actively. You may move to the room side within the allowable range. In other words, in the past, the beam was passed through the center of the column surface. However, the beam passage position was positively shifted to the room side on the column surface, and the space between the beam and the outer peripheral wall was increased. You may devise to expand the exclusive volume of the space.
[0020]
When the pipe shaft is provided using a small space, for example, among the outer peripheral wall portions provided with the windows, particularly, along the inner peripheral portion of the outer peripheral wall between the windows provided on the outer peripheral wall. It is preferable to do this.
[0021]
Usually, since the window has a daylighting function for the room, relatively large objects are rarely arranged on the inner surface of the outer peripheral wall having the window, and the use of such a space causes a trouble in layout. It is unlikely to be a problem. In particular, the inner peripheral portion of the outer peripheral wall between the windows is narrow, and the importance of layout in which objects are positively arranged in this portion is not considered so much.
[0022]
Therefore, even if a pipe shaft is provided along the inner peripheral part of the outer peripheral wall between adjacent windows, there is no worry that it will greatly limit the convenience of use of the conventional room space. The part that has not been used will be used effectively, and the pipe shaft can be installed in the room without impairing the use of the room.
[0023]
In addition, when a pipe shaft is provided at such a position, a water circulation unit such as a sink is placed under the window adjacent to the pipe shaft. It is possible to realize the arrangement of the water unit that does not require much trouble.
[0024]
Compared to the case where the branch pipe is drawn into the living room from the conventional pipe in the pipe shaft provided in the common part, the branch pipe can be remarkably shortened, and the labor of the branch pipe work can be greatly reduced.
[0025]
Moreover, in the present invention, since the pipe shaft is provided in the living room, when the layout of the living room is changed, the branch piping work can be easily performed, such as rearrangement such as water circulation that requires branch piping with the pipe in the pipe shaft. Therefore, it can be done easily. There is no need to consider new piping construction with a long piping route from the common pipe shaft.
[0026]
In addition, if there are a plurality of inner peripheral portions of the outer peripheral wall where the pipe shaft is provided between the windows, the pipe shaft for dredging pipes for water supply and drainage such as water and dredging pipes, drainage dredging pipes, and wires and communication wires are passed. A pipe shaft for the soot pipe may be provided separately. The pipe shaft can be installed at a reasonable location according to the situation of these pipes that are drawn into the building from outside the building.
[0027]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0028]
(Embodiment 1)
In the present embodiment, as shown in FIG. 1, pipe shafts 20 are provided so as to vertically pass through the respective rooms 10 of the respective floor portions of the building. In FIG. 1A, a state where the bird's eye is viewed so that the inner surface side of the outer peripheral wall 11 of the room 10 can be seen is shown.
[0029]
In the room 10, as shown in FIG. 1A, columns 30 are provided at predetermined intervals along the inner surface side of the outer peripheral wall 11, and windows 40 are provided in the outer peripheral wall 11 portion between the columns 30. ing. The window 40 is provided in the outer peripheral wall 11 portion between the pillars 30 so as to be adjacent to each other in the lateral direction with a space therebetween.
[0030]
The pipe shaft 20 is provided through each floor in the vertical direction along the inner peripheral surface portion 12 (FIG. 2) between the adjacent windows 40 in the inner surface portion of the outer peripheral wall 11. In the space used for the pipe shaft 20, the plan view of FIG. 2 showing the situation when looking down from above the beam 31, and the situation where the pipe shaft 20 is passed through the upper and lower floors as seen from the side of the column 30. As shown in the sectional view of FIG. 3, a small space having a narrow width W between the beam 31 provided between the columns 30 and the inner surface side of the outer peripheral wall 11 is used.
[0031]
For example, when a square steel pipe is used for the column 30 and an H-shaped steel is used for the beam 31, as shown in FIG. 3, as shown in FIG. Is provided toward the front side of the sheet of FIG. As shown in FIG. 2, since the beam 31 is provided in parallel along the inner surface of the outer peripheral wall 11, a small space is formed between the side portion of the beam 31 and the inner surface of the outer peripheral wall 11. .
[0032]
That is, a small space is formed between the inner surface side of the outer peripheral wall 11 and the inner surface side of the outer peripheral wall 11 of the horizontal flange 31a of the H-shaped steel used for the beam 31.
[0033]
In the conventional steel structure, the H-shaped steel used for the beam 31 has the width W1 of the upper and lower horizontal flanges 30a smaller than the width W2 of the side surface 30a of the square steel pipe column of the column 30, so When attached to the center, a small space having a narrow width W is inevitably formed between the inner surface of the outer peripheral wall 11 provided on the column 30 and the beam 31 by a difference corresponding to approximately (W2−W1) / 2. .
[0034]
The present inventors have noticed that it can be used as a space for the pipe shaft 20 through the upper and lower floors, paying attention to this small space that has not been particularly effectively used. Since it is a soot pipe that passes through the pipe shaft 20 to the upper and lower floors, it is sufficient that at least the small space has a width larger than the diameter of the soot pipe, and such a large space is not required. Exactly, the present inventors have noticed that the soot tube 40 can be passed through the small space formed between the beam 31 and the inner surface of the outer peripheral wall 11.
[0035]
In addition, such a small space is inevitably generated if the column 30 and the beam 31 are joined to the column 30 and the beam 31 by a conventional method using, for example, a square steel pipe or H-shaped steel. For example, when joining to the side surface 30a of the column 30 of the beam 31 such as H-shaped steel, as shown in FIG. Display), a small space to be formed may be secured as much as possible.
[0036]
The pipe shaft 20 is a part that passes through the room 10 in the space for pipe shaft provided in the small space provided between the beam 31 and the inner surface of the outer peripheral wall 11 through the ceiling 13 and the floor slab 14 of the upper floor. Is covered with a box-shaped cover 21. As shown in FIG. 3, the cover 21 is provided from the floor slab 14 to the ceiling 13 of the room 10 along the outer peripheral wall inner surface portion 12 having the above configuration.
[0037]
The cover 21 of the pipe shaft 20 may be provided by on-site construction. For example, if a precast concrete board (hereinafter abbreviated as PC board) is used, labor for on-site construction can be saved, and labor saving can be expected. .
[0038]
In the present embodiment, two pipe shafts 20 (20a, 20b) configured as described above are provided in the room 10 as shown in FIG. As shown in FIG. 1B, a door 22 is provided on the indoor front side of the box-shaped cover 21 of the pipe shaft 20, and the door 22 is opened as necessary to check the inside of the pipe shaft 20. Can be done.
[0039]
A water supply pipe and a gas pipe are passed through the pipe shaft 20a, and a water meter, a gas meter, and the like are also provided. In the pipe shaft 20b, a telephone line or a conduit through which an electric wire passes is passed, and the distribution board is provided with a branch wiring meter and the like. A window is provided on the front surface of the door 22 of the pipe shaft 20b so that a pointer such as a voltage can be confirmed as necessary.
[0040]
As shown in FIGS. 1 to 3, the front portion of the cover 21 of the pipe shaft 20 is provided so as to protrude to the indoor side to the vicinity of the vertical flange 31 b of the beam 31. Even if the front portion of the cover 21 protrudes to the maximum, it is necessary that the cover 21 does not protrude to the indoor side of the column 30. This is because the space on the indoor side from the pillar 30 becomes unusable due to the protrusion of the pipe shaft 20 if it protrudes from the pillar 30.
[0041]
Moreover, as shown to some extent in FIGS. 1-3, it is because the space which provides instruments, such as a water meter, in the near side of the soot pipe 50 (refer FIG. 5) is required to protrude. However, if such consideration is not necessary, it may be possible to retract even to the end of the horizontal flange 31a of the beam 31.
[0042]
In addition, since the pipe shaft 20 of the present invention is provided in each chamber, unlike the conventional configuration provided in the common portion, the ceiling of each chamber is connected to a drain pipe that is passed as a pipe 50 in the pipe shaft 20. A drain pipe can be connected by a short piping route from the air conditioner installed on the back, and can also be used as a drainage route for the drain pipe.
[0043]
Further, in the pipe shaft 20, when the electric pipe is passed as the soot pipe 50, unlike the case where the pipe shaft 20 itself is configured as a distribution board as described above, the distribution of electric power is provided in the pipe shaft 20. You may make it accommodate a board.
[0044]
(Embodiment 2)
In the present embodiment, a method for arranging a water circulation unit that can easily perform rational piping with a short piping route using the pipe shaft 20 having substantially the same configuration as that of the first embodiment will be described below.
[0045]
As shown in FIG. 5, the pipe shaft 20 is configured such that a narrow small space between the inner surface portion 12 of the outer peripheral wall between the two windows provided on the outer peripheral wall 11 and the beam 31 passes through the upper and lower floors. Yes. The cover 21 of the pipe shaft 20 is formed in a substantially box shape protruding to the indoor side up to the vicinity of the vertical flange 31b of the beam 31, and surrounds a small space as in the first embodiment.
[0046]
Around the beam 31, urethane spray 32 is applied as shown in FIG. Further, as shown in FIG. 6, a small beam 33 is passed toward the indoor side from the vertical flange 31 b portion of the beam 31, and urethane spray 32 is also provided around the small beam 33.
[0047]
The pipe shaft 20 is passed through a main pipe 50 serving as a main line such as a water supply pipe, a drain pipe, a gas pipe, and an electric pipe passing through the upper and lower floors of the building. 5-7, the solid pipe 50 and a part of branch pipe from it are shown by the solid line display which shows a piping route.
[0048]
As shown in FIG. 6, a window frame 41 is attached to a window opening provided in the outer peripheral wall 11 on the left and right sides of the pipe shaft 20, and a window 40 is provided by providing glass on the window frame 41. Under the window 40, a sink (kitchen unit) is arranged as a water unit 60. Such a situation is shown in FIG. 7 when looking down from above the beam 31. A sink is visible on the left and right sides of the pipe shaft 20, and its sink portion 61 is visible.
[0049]
Below the sink portion 61, a gas pipe or a water supply pipe branched from the vertical pipe 50 in the pipe shaft 20 is connected to the unit pipe of the water unit. When connecting such a branch pipe, unlike the conventional case, by providing the water circulation unit 60 adjacent to the pipe shaft 20 provided at the window side, the branch pipe can be made at an extremely short pipe distance, and the piping work can be simplified accordingly. Yes.
[0050]
6 to 7 show a state in which a sink is provided as the water unit 60, the water unit 60 may be a washstand, for example.
[0051]
【The invention's effect】
In the present invention, since the pipe shaft is passed through the living room part, even if a new water supply pipe request or a change in power supply capacity occurs due to the redesign of the living room, unlike the conventional configuration, it is installed in the shared part. There is no need to bother branch piping from the pipe shaft side through a long piping route, and branch piping can be performed at a short distance from the living room.
[0052]
In the present invention, since a so-called dead space between the inner surface of the outer peripheral wall and the beam, which has not been effectively used conventionally, is used, the pipe shaft is provided in the living room without deteriorating the convenience of the conventional living room part. be able to.
[0053]
In the pipe shaft of the configuration of the present invention, since the installation location is between the outer peripheral wall inner surface portion and the beam between the windows of the outer peripheral wall, the pipe shaft satisfying the above conditions can be installed in one living room portion. In many cases, a plurality of locations can be assumed, and a plurality of pipe shafts can be easily provided according to the type of the soot tube.
[0054]
In the present invention, since the pipe shaft is provided near the outer peripheral wall, for example, the pipe shaft material can be easily lifted and carried in as compared with the case where the pipe shaft is provided in the shared portion deep in each floor. .
[0055]
In this invention, since a pipe shaft can be comprised with a PC board, compared with the case where a pipe shaft is constructed by concrete placement in the field, for example, a construction man-hour can be reduced markedly.
