JP 2008-109791 A JP 2006-101652 A JP 2002-17030 A

  Conventionally, in a common groove formed in a basement of a road or the like, there is an example in which a power cable and a communication cable are separated and accommodated in the same groove. However, in residential land, the power cable and the communication cable are wired separately according to the electrical equipment technical standards and the telecommunication equipment technical standards. For this reason, the housing lot is separate for power and communication, and the housing lot shown in Patent Document 1 accommodates only the communication cable. The revision of the electrical equipment technical standards and telecommunications equipment technical standards in June 2017 made it possible to share residential land.

  However, the power cable is connected to a power meter, a lightning arrester, a distribution board, etc., which are arranged on the inner side of the house than the housing land, and then wired throughout the house. On the other hand, if the communication cable is a metal wire, it is connected to a protector and wired to a position where a communication device in the house is installed. If it is an optical fiber, it is connected to a terminating device such as an ONU (Optical Network Unit, optical line terminating device) installed in the home, and wired to the home by a wired or wireless LAN. Because of such wiring, the power cable and the communication cable are often drawn into the house at different positions. As a result, even if the residential land can be shared, the wiring from the residential land is often separated.

  In the past, considering the position where the cable is pulled into the house and the position where the cable is pulled out from the underground pipe or groove of the road, the arrangement of the residential land for power and communication should be determined independently according to the convenience of each. . When a residential land is shared, there is a problem that a position convenient for power is not necessarily a position convenient for communication. In particular, the difference in the position of drawing into the house has a great influence on this problem. An object of the present invention is to provide a common residential land that can easily secure the degree of freedom of wiring to a house.

  The shared housing lot of the present invention includes a peripheral portion, a bottom portion that closes the bottom of the peripheral portion, and a lid. In the case where the peripheral edge or the bottom has a hole or knockout for a roadside power cable and a hole or knockout for a roadside communication cable, the peripheral edge is at least 1/3 or more in one round of a predetermined height. It has a knockout area in the range of. When the peripheral portion is constituted by four surfaces, it has a knockout area on at least two surfaces. Or the common residential land of this invention has a knockout area in the range of 1/2 or more in the circumference part and the bottom part at least in one round of predetermined height. When the peripheral portion is composed of four surfaces, the knockout region is provided on at least three surfaces.

  The common residential land of the present invention has a knockout area on at least two sides when the peripheral part is composed of four sides or in a direction that is 1/3 or more of the peripheral part. With the shared housing lot of the present invention, the position of the power cable hole and the position of the communication cable hole on the inside of the house can be selected with a high degree of freedom, so that it can be easily adapted to the position to be pulled into the house. Therefore, it is easy to ensure the degree of freedom of wiring to the house.

  Hereinafter, embodiments of the present invention will be described in detail. In addition, the same number is attached | subjected to the structure part which has the same function, and duplication description is abbreviate | omitted.

  FIG. 1 shows the wiring from the road side to the house. In the basement of the road 910, a common groove 810, which is a groove in which a power cable and a communication cable are accommodated, is formed. In the case of electric power, there are cases where there are two power cables 820 and one power cable 820 between the common groove 810 and the common residential land 100 depending on the pull-in method. FIG. 1 shows the case of two. In the case of communication, one communication cable 830 is usually located between the common groove 810 and the common residential land 100. The common residential land 100 is arranged in the residential land 920. In FIG. 1, the common housing lot 100 is arranged in the basement of the parking lot 930, but it does not necessarily have to be the parking lot 930. From the common residential land 100, a power cable 825 on the inside of the house and a communication cable 835 on the inside of the house are wired in accordance with the position to be drawn into the house 920.

  2 is a plan view (viewed from above) of the common housing land of Example 1, FIG. 3 is a side view of the shared housing land of Example 1 viewed from the road side, and FIG. A sectional view taken along line -A is shown. The common residential land 100 of the first embodiment includes a peripheral edge portion 110, a bottom surface portion 120 that closes the bottom of the peripheral edge portion 110, and a lid portion 130. A space surrounded by the peripheral edge portion 110, the bottom surface portion 120, and the lid portion 130 is a housing portion 140 for housing a cable or the like. The peripheral edge 110 or the bottom surface 120 has a hole 111 for a road-side power cable 820 and a hole 113 for a road-side communication cable 830. 2 and 3, there are two holes 111, but one hole may be used depending on the method of drawing in the power cable. 2 and 3, the holes 111 and 113 are formed in the peripheral edge portion 110, but may be formed in the bottom surface portion 120 as in Patent Document 1. Also, in place of the holes 111 and 113, the knockout of the same size as the holes 111 and 113 is thinned so that the holes can be easily drilled. Part) may be formed.

  The lid part 130 includes an opening part 131 and a closing part 132. The lid part 130 is made of metal and covers the upper part of the peripheral edge part 110. The blocking part 132 is covered with soil, and the opening part 131 is at the same height as the ground surface 931. Therefore, the common residential land 100 can be made inconspicuous. Further, even after the common residential land 100 is installed, the cable can be laid or maintained by opening the opening 131.

  The peripheral portion 110 is configured by, for example, four surfaces, and has a knockout region 115 that is a thin region on two or more of the surfaces. In the example of FIGS. 2-4, it has a knockout area | region on three surfaces. Knockout area 115 is an area in which a hole for power cable 825 on the inside of the house and a hole for communication cable 835 on the inside of the house can be drilled with a drill or a cutter. The knockout area 115 is an area that is sufficiently wider than the cross section of the power cable and the communication cable, and the position of the hole can be freely selected. In other words, the “knockout area” means that a knockout having the same size as the holes 111 and 113 is not included. If the width of the knockout area 115 is limited by different expressions, for example, the knockout area 115 may be formed in a range of 1/3 or more in one round of a predetermined height that forms the knockout area. In FIG. 2, the knockout region 115 is formed in a range of about ½ in one round.

  Examples of the material for the peripheral edge portion 110 and the bottom surface portion 120 include resin concrete, general resin, and cement concrete. If the peripheral edge part 110 and the bottom face part 120 are made of resin-concrete unreinforced structure, the knockout region 115 can be easily formed only by reducing the thickness. If it is made of resin concrete, it is stronger than common cement concrete, so it can be made straight. Holes can also be drilled with a diamond core drill or cutter. Furthermore, if it is resin concrete, it is possible to divide the common housing lot 100 into several parts and assemble it on-site, and it is easy to deal with when the delivery period is short after order placement. However, it is not necessary to limit the knockout area to resin concrete as long as it is a material that can be made streak while maintaining the strength to withstand the pressure applied from the earth and sand, and can easily make holes. In the case of a general resin material, the cost can be reduced when manufacturing a large number of peripheral portions 110 and bottom portions 120 having the same shape. In the case of materials classified as cement concrete, since it is a general-purpose material, it is easy to reduce costs even when it is not manufactured in large quantities. The materials for the peripheral edge portion 110 and the bottom surface portion 120 may be appropriately selected in consideration of the characteristics of each material. “Non-reinforcement” means that there is no reinforcing bar to increase the strength of the structure. Note that a metal net (a metal net that is thin enough to be easily cut with a drill or a cutter) used to prevent scattering when the window glass is broken is not included in the above-described reinforcing bars. In the present specification, a structure including a metal net for preventing scattering is also included in the range of “bare”. The peripheral portion 110 and the bottom surface portion 120 made of resin concrete may have a metal net. If it has a metal net | network inside, when the knockout area | region 115 is cracked, it can prevent that resin concrete falls apart.

  The inner dimensions and thicknesses of the peripheral edge 110 and the bottom surface 120 of the common housing land 100 may be appropriately selected in consideration of the power cable pull-in method and the like. Generally, the width (horizontal direction in FIGS. 2 and 3) is 400 to 600 mm, the length (vertical direction in FIG. 2) is 700 to 900 mm, and the height (vertical direction in FIG. 3) is from 400 to 900 mm. However, it is not necessary to limit to these. Further, the thickness t1 other than the knockout region 115 may be selected from the range of 50 to 100 mm, and the thickness t2 of the knockout region 115 may be selected from the range of 20 to 30 mm, but it is not necessary to limit to these.

  In the common residential land of the present invention, the knockout area 115 is formed in a wide range, so that the degree of freedom of wiring between the power cable 825 and the communication cable 835 inside the house can be increased. When the knockout area 115 is provided on at least two surfaces, the power cable 825 and the communication cable 835 on the inside of the house can be pulled out in different directions at an angle of 90 degrees or more. Further, even when the range is more than 1/3 in one round, the same effect can be obtained because the power cable 825 and the communication cable 835 can be drawn out from a wide range. Therefore, with the common housing land of the present invention, it is easy to ensure the degree of freedom of wiring to the house.

[Modification 1]
In FIG. 5, the figure which looked at the peripheral part of the common housing lot of the modification 1 from the top is shown. The common residential land 101 has a donut shape at the peripheral edge 110. Although the bottom surface portion 120 and the lid portion 130 are not shown in the drawing, the bottom surface portion 120 and the lid portion 130 may be shaped to match the shape of the peripheral edge portion 110. Also in the case of the peripheral edge 110 of the common residential land 101, the knockout area 115 may be formed in a range of 1/3 or more in one round of a predetermined height that forms the knockout area. In the example of FIG. 5, knockout region 115 is formed in a range of about ½ in one round. In the case of the donut-shaped peripheral edge 110, if the knockout area 115 is formed in a range of 1/3, the direction of the holes of the power cable 825 and the communication cable 835 on the inside of the house can be selected from 120 degrees. Therefore, with the common housing land of the present invention, it is easy to ensure the degree of freedom of wiring to the house.

[Modification 2]
FIG. 6 is a plan view (viewed from above) of the common housing land of the second modification, FIG. 7 is a side view of the common housing land of the second modification viewed from the road side, and FIG. Sectional drawing in the -B line is shown. A common residential land 100 of Modification 2 includes a peripheral edge 112, a bottom face 120 that closes the bottom of the peripheral edge 112, and a lid 130. A space surrounded by the peripheral edge portion 112, the bottom surface portion 120, and the lid portion 130 is a housing portion 140 for housing a cable or the like.

  In the modified example 2, the road-side power cable hole and the road-side communication cable hole are not formed in the peripheral edge portion 112 and the bottom surface portion 120. As described above, when all or part of the road-side cable holes or knockouts are not formed, it is necessary to open a road-side power cable hole and a communication cable hole. Therefore, in the common residential land 100 shown in FIG. 2, the road 111 for the power cable on the road and the hole 113 for the communication cable on the road are formed in the common residential land 102 shown in FIG. 6. Region 115 is formed. Further, the two surfaces of the peripheral edge portion 112 are made the entire surface as a knockout region 116 by reducing the thickness of the entire surface. That is, the peripheral portion 112 is configured by four surfaces, and has knockout regions 115 and 116 that are thin regions on the four surfaces. In the second modification, the knockout portions 115 and 116 are drills or cutters, and are used for a road-side power cable hole, a road-side communication cable hole, a house-side power cable hole, and a house-side communication cable. This is the area where you can drill holes.

  Even if the knockout areas 115 and 116 are not formed on four surfaces, if the knockout areas 115 and 116 are formed on at least three surfaces, it is easy to secure the degree of freedom of wiring to the house. In addition, when a different expression is used in consideration of the case where the peripheral portion 112 is not configured by four surfaces, the peripheral portion 112 is at least a half of a predetermined height in a range of 1/2 or more. And a knockout area, which is a region where a hole for a roadside power cable, a hole for a roadside communication cable, a hole for a power cable inside the house, and a hole for the communication cable inside the house can be formed.

  Similarly to the common housing land 100, if the peripheral edge 112 and the bottom surface 120 are made of resin concrete, the knockout areas 115 and 116 can be easily formed simply by reducing the thickness. The definition of “muscleless” is the same as in the first embodiment. Further, if a metal net (a metal net thin enough to be easily cut by a drill or a cutter) is provided inside the peripheral portion 112, the resin concrete is separated when the knockout areas 115 and 116 are broken. Can be prevented.

  The inner dimensions and thicknesses of the peripheral portion 112 and the bottom surface portion 120 of the common residential land 102 may be appropriately selected in consideration of the power cable drawing method and the like, and the thickness of the knockout area 116 that is the same as that of the shared residential land 100 Although t3 should just be about 50 mm, it is not necessary to limit to these.

  In the common residential land of the present invention, the knockout areas 115 and 116 are formed in a wide range, so the degree of freedom of wiring between the power cable 825 and the communication cable 835 inside the house can be increased. When knockout areas 115 and 116 are provided on at least three surfaces, the power cable 825 and the communication cable 835 on the inside of the house can be pulled out in different directions at an angle of 90 degrees or more. Further, even when the range is more than 1/2 in one round, the same effect can be obtained because the power cable 825 and the communication cable 835 can be drawn out from a wide range. Therefore, the shared housing lot of the modified example 2 is easy to ensure the degree of freedom of wiring to the house.
