JP5079748B2 - An underground trench structure that facilitates maintenance and renewal of common facilities in an apartment house and an apartment house using the same - Google Patents

Description

  The present invention is an apartment house having a plurality of floors such as an apartment, and in particular, maintenance (inspection, cleaning, repair, replacement, etc.) of piping such as drainage pipes, electric wires, gas pipes, water supply pipes, etc., and their updating are easy. This is related to an underground trench structure.

  There is an increasing tendency to demand long-lived apartments of 100 years or longer (for example, 300 years), but in order to make apartment houses live longer (for example, over 300 years), Even if the owner changes, it is desirable that the floor plan and the like can be flexibly changed accordingly. More specifically, a skeleton / infill separation idea has been proposed in which a residence is separated into a housing part (skeleton) and a part (infill) that can be changed as desired by the resident.

  An apartment house consists of a plurality of levels, and each level has a plurality of dwelling units. It is necessary to supply electric power, gas, water, etc. to each of these units, and it is necessary to discharge the waste water from each unit. For this reason, the housing complex is provided with a piping space penetrating these levels, and various types of pipes are arranged in the piping space.

  (First example) Normally, the pipes of electricity, gas, water, etc. are arranged so as to penetrate through the rooms of each dwelling unit on each floor so that the pipes can be piped to the basement. A pit is provided in the basement and directly below each dwelling unit on the first floor. The pits are gathered in the pit and connected to a large-diameter horizontal pipe.

  The horizontal pipe is buried in the ground outside the building from the pit of the housing complex to the vertical projection plane of the housing complex. For example, when the horizontal pipe is a drain pipe, the horizontal pipe is led to the road side beyond the housing complex premises and connected to the public sewer pipe through the sewage pipe buried in the underground of the road. The

  When the horizontal pipe is for a power cable, an electric wire is drawn from a utility pole on the road to a utility pole provided in the site, and the voltage is lowered by a transformer to connect to each dwelling unit.

  (Second Example) In addition to this, there is an example in which the piping space and the tub pipe in the piping space are arranged vertically outside the room such as a balcony or a corridor instead of the room of each dwelling unit.

  However, also in this example, the horizontal drawing pipe after the vertical pipes are collected is embedded in the ground in the same manner as described above.

  Now, in order to extend the life of the apartment house as described above, it is necessary to improve the maintainability of the vertical pipe and the horizontal pipe. This applies to any of the piping space, the basement below the residence, and the horizontal pipe.

  As in the first example, if the piping space and the soot pipe in the piping space are provided in the room of each dwelling unit, the construction person will naturally enter each dwelling unit. It becomes difficult. This is not only because the piping space is narrow, but also because the interior of each dwelling unit (such as the wall in which the pipe is stored) is likely to be damaged.

  In both the first and second examples, most of the horizontal pipes are buried underground, but every time you try to maintain the horizontal pipes, you need to dug the ground. However, when the surface of the soil is paved with concrete or asphalt, it is necessary to remove part of the finish.

As described above, in the prior art, the maintenance performance of the vertical pipe and the horizontal pipe before being connected to the horizontal pipe is low, which is an obstacle when the apartment house is used for extending its life.

  Then, this invention can improve the maintainability of piping, and as a result, it aims at providing the underground trench structure which is easy to maintain and update common facilities in an apartment house which can contribute to the lifetime extension of an apartment house. .

  The underground trench structure according to the first invention is an underground trench structure in which a plurality of dwelling units are provided per floor, and maintenance and renewal of shared facilities is easy in an apartment house having the plurality of floors, and is vertically Arranged underground pipes (outer pipes) that penetrate multiple levels outside the room of multiple dwelling units, and in the basement of the vertical projection plane of the apartment house, an underground trench consisting of a basement connected to the vertical pipe (outer pipe) In addition, an extension trench consisting of a basement extending from the underground trench to the boundary of the apartment house site beyond the vertical projection plane of the apartment house is connected continuously, and a horizontal pipe to which the vertical pipe (outer pipe) is connected is connected to the underground trench and It is arranged in the extension trench, and both the underground trench and the extension trench are shaped so that a person can enter inside.

  In this configuration, because the soot pipe (outer piping) is placed outside the dwelling unit, when maintaining the soot pipe (outside piping), the maintenance can be performed without the construction worker entering the dwelling unit, and there is little impact. Can be implemented. Specifically, it is possible to omit work that causes noise and vibration, such as hanging a concrete slab or the like through which a wall of a dwelling unit or a vertical pipe (outer pipe) penetrates.

  In addition, it is placed in the underground trench and extension trench, and the underground trench and extension trench are shaped so that people can enter inside. Or maintenance of a horizontal drawing pipe can be performed. Here, it is desirable to replace all the main pipes, for example, every 50 years, regardless of whether the main pipes have deteriorated, such as maintenance of traffic lights. In other words, the idea is not to replace it after it gets worse, but to change it before it gets worse. In this way, the main will continue to be used under normal conditions. According to this configuration, it is possible to cope with such a concept very easily.

  In addition, an extension trench consisting of a basement that extends from the underground trench to the boundary of the apartment housing site across the vertical projection plane of the apartment housing is connected, so most of the horizontal pipes to which the pipes (outer piping) are connected Is inside the underground trench or extension trench and is not buried in the ground.

  Therefore, it is possible to perform maintenance easily and silently without digging most of the horizontal draw pipe into the ground or peeling the pavement.

  In addition to the first invention, the underground trench structure according to the second invention includes a terrace trench provided in a lower part of a terrace of a first floor dwelling unit, and a corridor trench provided in a lower part of a corridor in contact with a plurality of dwelling units. including.

  With this configuration, two pipes (outer pipes), that is, a terrace trench and a corridor trench can be secured, and pipes can be piped from the room to the preferred side of these two systems.

  In the underground trench structure according to the third invention, in addition to the first invention, the underground beam supporting the apartment house is arranged in the ground, and the underground beam is located at the location from the vertical pipe (outer piping) to the underground trench. Piping space is secured by lowering the floor from the slab.

  In this configuration, the underground beam is placed in the ground, and the piping space is secured from the dredger pipe (outer pipe) to the underground trench, so the lower end of the dredger pipe (outer pipe) and the horizontal draw pipe Connection with the tip and bending margin can be easily secured, and a reasonable piping can be realized.

  In addition to the third invention, the underground trench structure according to the fourth invention further includes an inspection hatch and a material carrying hatch formed larger than the inspection hatch.

  In this configuration, the inspection hatch can be opened, the inside of the underground trench can be visually observed, and the piping can be easily inspected. Moreover, if a large material carrying hatch is opened, equipment such as a long pipe can be easily carried into the underground trench.

  According to the present invention, a construction worker enters each trench and easily performs maintenance of a pipe (outer pipe) or a horizontal pipe without causing noise or vibration such as hanging on a wall or floor of a dwelling unit. be able to.

  In addition, maintenance can be performed easily and silently without digging underground or peeling the pavement.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an apartment house in an embodiment of the present invention.

  The apartment house 1 shown in FIG. 1 includes a first floor 10, a second floor 20, a third floor 30, and a fourth floor 40. Of course, the present invention can be similarly applied to cases where the number of floors is further increased or decreased. .

  FIG. 1 shows the apartment house 1 as viewed from the corridor side, but the corridor 11 is shown only in the first floor 10 and the corridors are omitted for the second floor 20 or higher so that the illustration is easy to understand. is there.

  Immediately below the corridor 11 of the first floor 10 is an underground trench 50 made of a basement having a cross section of, for example, 2 meters square so that people can pass. The basement wall is made of reinforced concrete.

  The underground trench 50 exists inside the vertical projection plane when the apartment house 1 is viewed from above. The apartment house 1 is built on a certain site, and a boundary 70 with the road 80 exists on the site.

  In addition, an extension trench 60 including a basement extending from the underground trench 50 to the boundary of the site of the apartment house 1 beyond the vertical projection plane of the apartment house 1 is provided in series. Similarly to the underground trench 50, the extension trench 40 is also composed of a basement having a cross section of, for example, 2 meters square so that a person can pass through, and the wall of the basement is formed of reinforced concrete.

  A public sewer pipe 81 is buried under the road 80, and a manhole 82 is appropriately provided in the public sewer pipe 81.

  Furthermore, the power transmission line 63 and the communication line 66 managed by the power company or the communication company are arranged so as to pass near the site of the apartment house 1. In the example of FIG. 1, the power poles 61 and 62 are built in the site of the apartment house 1, the power transmission line 63 is connected to the transformer 64 supported by the power pole 61, and the transformer 64 is further connected to the switchboard 65. Similarly, the communication line 66 is also connected to the switchboard 65.

  Now, the entrance doors 12, 22, 32, 42 are respectively provided on the corridor side of each floor of the apartment house 1, and the side of the entrance doors 12, 22, 32, 42 are respectively in the positions corresponding to the upper and lower sides. Piping facilities 13, 23, 33 and 43 are arranged.

  In each piping facility 13, 23, 33, 43, drain pipes 14, 24, 34, 44 for flowing drain water downward, water supply pipes 15, 25, 35, 45 for supplying water to each floor, gas to each floor The gas pipes 16, 26, 36, 46 to be supplied and various meters for measuring the flow rate of these pipes are arranged.

  Furthermore, each piping facility 13, 23, 33, 43 may include an electric system such as a power line or a communication line for supplying power.

  In addition, although mentioned later for details, it is the position under each piping installation 13,23,33,43, and the corridor trench 51 which follows the underground trench 50 in the directly under 1st hierarchy.

  Each drain pipe 14, 24, 34, 44 passes through the corridor trench 51 and is connected to the horizontal drain pipe 52. The horizontal drainage pipe 52 is mostly located in the underground trench 50 or the extended trench 60 connected to the underground trench 50, and only the portion beyond the boundary 70 of the apartment house 1 is underground (that is, the road). 80).

  Therefore, most of the horizontal drainage pipe 52 can be maintained only by a person entering the underground trench 50 and the extension trench 60. At this time, it is not necessary to dig underground.

  Similarly, each of the water supply pipes 15, 25, 35, 45 and each of the gas pipes 16, 26, 36, 46 is connected to the horizontal water supply pipe 53 and the horizontal gas pipe 54, respectively. The horizontal water supply pipe 53 and the horizontal gas pipe 54 are mostly located in the underground trench 50 or the extended trench 60 connected to the underground trench 50, and only the part beyond the boundary 70 of the apartment house 1 is located. Located in the ground (ie, under the road 80).

  Therefore, most of the horizontal water supply pipe 53 and the horizontal gas pipe 54 can be maintained by a person entering the underground trench 50 and the extension trench 60. At this time, it is not necessary to dig underground.

  In this embodiment, the electrical system collected in the switchboard 65 is also drawn into the extension trench 60 from below the switchboard 65, and further supplied to each level through the underground trench 50. Easy maintenance is possible as described above.

  FIG. 2 is an elevation view of the apartment house in one embodiment of the present invention.

  As shown in FIG. 2, in particular, in the horizontal drainage pipe 52, the underground trench 60 and the extension trench 60 are provided with a gradient that lowers the public sewer pipe 81 side, thereby enabling drainage by natural flow.

  In FIG. 1, each line of the piping facilities 13, 23, 33, 43 and the corridor trench 51 is illustrated, but as illustrated in FIG. 2, such a line may be provided as many as necessary. Can do.

  FIG. 3 is a vertical sectional view of the apartment house in one embodiment of the present invention. As shown in FIG. 3, in this embodiment, not only the hallway trench 51 but also a terrace trench 55 that is usually disposed on the opposite side (terrace or balcony side) to the hallway is provided.

  For both the terrace trench 55 and the corridor trench 51, the beams supporting the first level are lowered to the underground beams 75 and 17 rather than the large beams 76 and 27 supporting the two or more levels, and the terrace trench 55 and the corridor trench 51. It should be noted that the height is secured and the connection to the horizontal drain pipe 52 is facilitated.

  In any of the first floor 10, the second floor 20, the third floor 30, and the fourth floor 40, the indoor drain pipes 18, 28, 38, and 48 are arranged, and are provided with an appropriate gradient so that the drain pipes on the corridor side or terrace / balcony side are provided. Of these, it can be connected to the drainage pipe on the preferred side.

  FIG. 4A is a plan view of a hallway trench according to an embodiment of the present invention, and FIG. 4B is a vertical sectional view of the hallway trench. It will be easier to understand that FIG. 4 shows that the beam supporting the first level is lowered to the underground beam 17 rather than the large beam 27 supporting two or more levels. When lowered in this way, a member such as an elbow that ensures bending of the tube can be installed smoothly.

  Further, since the corridor trench 51 is also a basement, a lower pit 57 (for example, 600 mm square) is provided at the lower part of the corridor trench 51, and when water leaks, the water accumulated in the pit 57 is pumped ( (Not shown).

  It is desirable that the hallway trench 51 has the same width as the hallway width under the common hallway and has a height of about 2 meters that is easy for humans to work. As shown in FIG. 4, for example, it is desirable to provide an inspection hatch 58 of about 600 mm square at a ratio of about one place in two dwelling units.

  Then, the person performing the inspection work can open the inspection hatch 58 and enter the corridor trench 51, and further move to the underground trench 50 and the extension trench 60 to inspect and clean the equipment.

  Although not shown in FIG. 4, it is desirable to provide a material carry-in hatch approximately twice as long as the inspection hatch 58 (for example, a longitudinal dimension of 1200 mm). In this way, a long material (for example, about 4 meters) such as a horizontal drain pipe can be carried into the corridor trench 51, the underground trench 50, and the extension trench 60.

  The equipment such as horizontal drainage pipes should be completely replaced at regular intervals (for example, every 50 years) whether or not they are deteriorated, as in the case of traffic signal maintenance. For example, it can be carried out without digging up underground.

  As shown in FIG. 4A, the drainage from the drainage pipes 24, 34, 44 from two or more levels is connected to the horizontal drainage pipe 52 via the upper floor drainage pipe 72. Drainage from the drainage pipe 14 of the first floor 10 is connected to the horizontal drainage pipe 52 via the first-floor drainage pipe 71 different from the upper-floor drainage pipe 72.

  This is to prevent a backflow from occurring in the first level drainage pipe 14 due to the water pressure of the drainage from the upper floor when the drainage pipe 14 of the first level 10 is directly connected to the upper level drainage pipe 72.

  FIG. 5A to FIG. 5C are vertical sectional views of terrace trenches in one embodiment of the present invention. It will be easier to understand that FIG. 5 shows that the beam supporting the first level is lowered to form the underground beam 75 rather than the large beam 76 supporting two or more levels. When lowered in this way, a member such as an elbow that ensures bending of the tube can be installed smoothly.

  The terrace trench 51 is preferably 600 mm wide and about 1.8 meters high from the column surface under the terrace of one layer. Although it is called a terrace trench, even if there is no terrace, the same effect can be obtained if it is formed along the line where the drain pipe descends on the balcony side. This includes cases where there is no terrace.

  Similarly to the corridor trench 51, the terrace trench 55 is preferably provided with an inspection hatch of about 600 mm square and a material loading hatch, for example.

  In addition, as shown in FIG.5 (b), although the waste_water | drain from the drainage pipe from the 2nd hierarchy or more is connected to the horizontal drainage pipe 52 via the upper floor drainage pipe 74, FIG.5 (c) ), The drainage from the drainage pipe of the first floor 10 is connected to the horizontal drainage pipe 52 via the first floor drainage pipe 73 different from the upper floor drainage pipe 74. This is to prevent backflow from occurring in the drainage pipe of the first floor due to the water pressure of the drainage from the upper floor, as described above.

  FIG. 6 is an exemplary diagram of the layout of the corridor trench, terrace trench, underground trench and extension trench in one embodiment of the present invention. Since the corridor trench 51 and the terrace trench 55 are usually arranged along the lower part of the corridor and the terrace of the building as shown in the drawing, the layout of the building is almost fixed when the structure of the building is determined.

  The underground trench 50 can be arbitrarily laid out if the corridor trench 51 and the terrace trench 51 can be connected. In the example of FIG. 6, the underground trench 50 is formed with a width of about one dwelling unit on one wife side of the building.

  This is because the site of the apartment house 1 faces the road 80 on the wife side, and the extension trench 60 is arranged between the underground trench 50 and the road 80 to connect them.

  However, there are various patterns in how the site of the housing complex 1 is in contact with the road, and the layout of the underground trench 50 and the extension trench 60 is reasonably determined accordingly. Therefore, the trench layout of the present invention is not limited to the illustrated example, and various layouts are also included in the present invention.

  Specifically, FIG. 7A to FIG. 7F illustrate layouts according to roads and sites in one embodiment of the present invention. In this way, the manner in which the road 80 contacts the site 100 is various. In the figure, the portions marked with light ink indicate locations where trenches are provided, and the arrows indicate the flow direction of drainage.
