Description

[Technical Field]

[0001] The present invention relates to a pole workpiece and a method for installing the pole workpiece. [Background technology]

[0002] A method known as the footing method is used to erect poles (supports).

[0003] For example, Patent Document 1 presents a cross-sectional view of the base part of a pole called a footing (Figure 1, symbol 2 in Patent Document 1), and as shown in Figure 5 in Patent Document 1, construction is completed by digging a hole in the ground, installing the base part, and then installing a support pole in the base part and backfilling it. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-240010 Summary of the Invention [Problem to be solved by the invention]

[0005] In the footing method, in order to prevent the pole from tipping over and the ground from subsiding due to the weight of the pole and the foundation, it is necessary to use a large foundation so that the contact area between the bottom of the excavated hole and the bottom of the foundation is large. Therefore, there is a problem that the installation area becomes large. In addition, the construction process is time-consuming, as it requires digging a hole large enough to fit the foundation and then backfilling it.

[0006] Therefore, the object of the present invention is to provide a pole structure and a method for installing a pole structure that includes a pole member that suppresses ground subsidence and is less likely to tip over even if the base has a small installation area. [Means for solving the problem]

[0007] After thorough research into the above-mentioned problems, the inventor discovered that the outer periphery of the cylindrical base is uneven in the diameter direction, and that these unevennesses come into contact with the soil on the ground, making it difficult for the pole structure to tip over, and that the installation area of ​​the base can be reduced, thereby preventing ground subsidence due to its own weight, and thus completed the present invention.

[0008] The pole structure of the present invention for solving the above problems comprises: a cylindrical base portion buried in the ground to a depth of 1.0 m to 4.5 m and a diameter of 0.4 m to 1.5 m; A pole member having a length of 4.0 m to 20.0 m from the ground surface, which is arranged in the center of the base, The base portion includes a concrete member and a concrete reinforcing member, The concrete reinforcement member is a reinforcing bar member in which rod-shaped members are arranged in a lattice pattern. The concrete reinforcement member is disposed inside the concrete member, One end of the pole member is fixed with a concrete member. The outer periphery of the base is uneven in the diameter direction, and the unevenness comes into contact with the soil on the ground.

[0009] According to the pole structure of the present invention, the outer periphery of the base is uneven in the diameter direction, and since these unevennesses come into contact with the soil on the ground, friction is generated between the base and the ground, making it less likely to tip over and allowing the installation area of ​​the base to be reduced. Furthermore, since the base portion is equipped with concrete members and concrete reinforcing members, the strength of the base portion can be increased, which also has the effect of firmly holding the pole members.

[0010] Furthermore, the pole structure of the present invention comprises: a cylindrical base portion buried in the ground to a depth of 1.0 m to 4.5 m and a diameter of 0.4 m to 1.5 m; A flange portion that is located above the center of the depth direction of the base portion and that extends horizontally beyond the diameter of the base portion; A pole member having a length of 4.0 m to 20 m from the surface of the ground, which is arranged in the center of the base, The base portion includes a concrete member and a concrete reinforcing member, The concrete reinforcement member is a reinforcing bar member in which rod-shaped members are arranged in a lattice pattern.

Furthermore, since the flange is installed on top of the base, it provides greater support for the pole, making it less likely to tip over.

DETAILED DESCRIPTION OF THE INVENTION

[0062] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, with reference to the drawings, embodiments of a pole structure including a base and a pole member according to the present invention and a method for installing the pole structure will be described in detail. It should be noted that the pole structure and the pole structure installation method described in the embodiments are merely examples provided to explain the pole structure and the pole structure installation method according to the present invention, and are not limited thereto.

[0063] In addition, when a signboard is attached to the other end of the pole member of the pole work, it becomes a signboard work, and the pole work and the pole work installation method of the present invention can be particularly preferably applied to signboard works. It is particularly preferable that the signboard be installed at the tip of the pole member above half the height of the pole member above ground level (on the side opposite the ground).

[0064] [First embodiment] [Pole structure] Referring to FIG. 1, a pole workpiece 101 in a first embodiment will be described. In this embodiment, the pole workpiece 101 comprises a base portion 1, a pole member 2, and a concrete encasing member 3.

[0065] <Base> The base 1 serves to support the pole member 2 so that it does not fall over. The base 1 includes a concrete member 11, a concrete reinforcing member 12, a self-supporting support member 13, and a flange 14. The base 1 has a cylindrical shape, and its upper surface is placed at the same height as or near the ground surface 91. The base 1 becomes the base of the pole member 2 when a concrete member 11 is filled in a hole 111 dug with a digging tool called an auger 8 shown in Figure 2. The auger 8 is a tool that has a shaft portion 81 that serves as the axis of rotation and a spiral member 82 that is attached around it. When drilling a hole in the ground 9, the shaft portion 81 rotates and is sent underground, and the soil dug up by the spiral member 82 is sent to the side of the ground surface 91, thereby digging a hole 111.

[0066] Returning to Figure 1, as shown in the enlarged partial view of Figure 1A, the cylindrical base portion 1 has an outer periphery that is uneven in the diameter direction, and the uneven portion is in contact with the unevenness 116 of the soil of the ground 9 (side wall 112 of hole 111) so as to penetrate into it. The unevenness 115 on the peripheral surface of the base 1 is realized by pouring the concrete member 11 into a hole 111 dug by an auger 8, and the presence of this unevenness 115 creates friction between the ground 9 and the base 1, making it possible to create a structure in which the pole member 2 is less likely to tip over.

[0067] In the conventional footing method, a portion of a concrete base is covered with soil to enlarge the base itself in the planar direction, and the weight of the base prevents the pole member from tipping over. However, the inventors of the present invention have discovered that tipping can be prevented by friction between the unevenness 115 on the outer surface of the cylindrical base portion 1 and the unevenness 116 on the side wall 112 of the hole 111 in the ground 9. With the base portion 1 of the present invention, the installation area (when viewed from above the ground surface 91) can be reduced and its own weight can also be kept small, resulting in a pole structure 101 that is less likely to cause ground subsidence.

[0068] The depth of the base 1 (D shown in Figure 1, which can also be referred to as height) is not particularly limited, but specifically, a depth from the ground surface 91 of 1.0 m or more to 4.5 m or less is applicable. The lower limit of the depth is preferably 1.2 m or more, more preferably 1.6 m or more, even more preferably 2.0 m or more, even more preferably 2.5 m or more, and most preferably 3.0 m or more. The upper limit of the depth is preferably 4.0 m or less, more preferably 3.5 m or less, and even more preferably 3.0 m or less. These ranges are preferable in that they make it easier to ensure the area (friction) of the irregularities 115 on the outer periphery of the base part 1 and also ensure the weight required to support the pole member 2.

[0069] The diameter of the base 1 (φ1 shown in FIG. 1) is not particularly limited, but specifically, a diameter of 0.4 m or more and 1.5 m or less is applicable. The lower limit of the diameter is preferably 0.6 m or more, more preferably 0.8 m or more, and even more preferably 1.0 m or more. The upper limit of the diameter is preferably 1.2 m or less, and more preferably 1.0 m or less. These ranges are preferable from the viewpoint of reducing the installation area, and are also preferable from the viewpoint of making it easier to ensure the area (friction) of the irregularities 115 on the outer periphery of the base part 1.

[0070] <<Concrete components>> The concrete member 11 is not particularly limited as long as it can support the pole member 2 by hardening from a liquid state into a solid and can fit into the unevenness of the side wall 112 of the hole 111 dug in the ground 9. Specifically, mortar or concrete can be used, but concrete is preferable from the viewpoint of strength.

[0071] <<Concrete reinforcement members>> The concrete reinforcing member 12 is disposed inside the concrete member 11 and serves to increase the strength of the base portion 1. A reinforcing steel member, which is made of metal rod-shaped members arranged in a lattice pattern, is preferably used as the concrete reinforcing member 12. By using a reinforcing steel member, it is easier to fill with the liquid concrete member 11, and the strength of the base 1 can be improved. The concrete reinforcing member 12 may be placed inside the concrete member 11, but by using a cylindrical concrete reinforcing member 12 that surrounds the pole member 2, the strength of the base portion 1 can be increased evenly. Note that it is preferable to make the concrete reinforcing member 12 cylindrical, with a smaller diameter than the cylindrical base portion 1 (hole 111), and to place the pole member 2 inside the cylindrical body, as this increases the strength of the base portion 1 more evenly and allows it to evenly withstand the force of the pole member 2 trying to tip it over. The concrete reinforcing member 12 has a height that is more than half the height of the base 1, and is substantially the same height as the base 1. The concrete reinforcing member 12 is embedded in the base 1.

[0072] <<Standing support parts>> The self-supporting support member 13 is a tubular or rod-shaped member fixed to the pole member 2, and serves to support the pole member 2 so that it does not fall over. The material of the self-supporting support member 13 is not particularly limited, but it is preferably made of metal from the viewpoint of strength. When the pole member 2 is made of metal, it is preferable to use a metal support member 13 as well, since the pole member 2 and one end side 132 of the support member 13 can be firmly fixed to each other by welding. The self-standing auxiliary members 13 are arranged partly or entirely inside the concrete member 11 of the base 1 in a state where they intersect (diagonally) in the horizontal and vertical directions. In addition, the other end side 131 of the self-supporting auxiliary member 13 passes through the lattice holes of the concrete reinforcement member 12 and is positioned so as to be stuck into the ground 9 or in contact with the concrete reinforcement member 12. If the other end side 131 of the self-supporting auxiliary member 13 is in contact with the concrete reinforcement member 12, it is effective in preventing the pole member 2 from tipping over, but as shown in Figure 1, it is preferable to have the other end side 131 of the self-supporting auxiliary member 13 pass through the lattice holes of the concrete reinforcement member 12 and be stuck into the ground 9, in order to further prevent the pole member 2 from tipping over. Note that even if the other end side 131 of the self-supporting auxiliary member 13 passes through the lattice holes of the concrete reinforcement member 12 and is in contact with the side wall 112 of the hole 111, it is possible to prevent the pole member 2 from tipping over.

[0073] <<Flange>> The flange 14 is provided above (on the ground surface 91 side of) the center of the base 1 in the depth (D) direction, and is a member that extends horizontally beyond the diameter (φ1) of the base 1. The flange portion 14 has its bottom surface 141 received in a flange groove portion 142 dug in the ground 9, supporting the weight of the pole workpiece 101 and serving to prevent ground subsidence, and also having the effect of preventing the pole member 2 from tipping over. The flange 14 is made of a concrete member 11, and a flange reinforcing member 143 is disposed inside the flange 14. The flange reinforcing member 143 is a member that increases the strength of the flange 14. The flange reinforcing member 143 is a reinforcing bar member made of metal rod-shaped members arranged in a lattice pattern. The flange reinforcing member 143 only needs to be placed inside the flange 14, and is preferably connected and fixed to the concrete reinforcing member 12, as this further improves the strength of the flange 14.

[0074] <Pole components> The pole member 2 has one end 21 fixed to the concrete member 11 of the base 1. The material of the pole member 2 is not particularly limited, but is preferably made of metal from the viewpoint of reducing the installation area and ensuring strength. The pole member 2 may be a hollow tubular member or a solid rod-shaped member. However, a tubular member is preferable from the viewpoint of suppressing ground subsidence due to its own weight, since it can be made lighter. Furthermore, the shape of the outer periphery of the horizontal (diameter) cross section of the pole member 2 is not particularly limited, but if the outer periphery is rectangular, there is a flat portion, which has the effect of making it easier to secure a large contact area for the self-supporting support member 13 and making it easier to fix. On the other hand, if the outer periphery is circular, there is more freedom in the installation direction than when the outer periphery is polygonal, which has the effect of allowing (making it easier to install) the self-supporting support member 13 at any angle (see Figure 16; installation direction of the self-supporting support member 13 in a plan view).

[0075] As shown in FIG. 1, the thickness φ2 of the pole member 2 (diameter in the case of a cylinder, the length of the diagonal in the case of a polygon, or the diameter of the circumscribed circle in the case of a polygon) is not particularly limited, but specifically, a thickness of 0.10 m or more and 0.70 m or less is applicable. The lower limit of the diameter φ2 is preferably 0.20 m or more, more preferably 0.30 m or more, even more preferably 0.35 m or more, even more preferably 0.40 m or more, and most preferably 0.45 m or more. The upper limit of the diameter φ2 is preferably 0.65 m or less, more preferably 0.6 m or less, even more preferably 0.55 m or less, and even more preferably 0.50 m or less. These ranges are preferable in terms of the installation area of ​​the base part 1 that supports the pole member 2.

[0076] The height H of the pole member 2 (height from the ground surface 91 to the tip of the pole member 2) is not particularly limited, but specifically, a height of 4.0 m or more and 20 m or less is applicable. The lower limit of the height H is preferably 6.0 m or more, more preferably 8.0 m or more, and even more preferably 10 m or more. The upper limit of the height H is preferably 15 m or less, and more preferably 10 m or less. These ranges are preferable in terms of reducing the weight of the pole member 2 and suppressing ground subsidence while ensuring the height of the pole member 2. Furthermore, these ranges are particularly suitable when used as signboard structures, as they are at a height that is easily noticeable.

[0077] Furthermore, one end side 21 of the pole member 2 may be separated from the ground (the end of the pole member 2 may be embedded inside the concrete member 11), but if the pole member 2 is structured so that it comes into contact with the bottom surface 114 of the hole 111 at the bottom of the base portion 1, the pole member 2 is more supported by the base portion 1 and also by the ground (it is directly supported by the ground), which has the effect of making the pole member 2 more stable and less likely to fall over. The bottom surface 114 of the hole 111 may be subject to soil conditions, or may be subjected to compaction work to harden the ground, such as adding crushed stone to compact the ground. When such ground stabilization work or an object (not limited to crushed stone) is placed, the bottom surface 114 becomes the surface, and this includes the meaning that the pole member 2 comes into contact with the ground at the bottom of the base portion 1. Although one end side 21 of the pole member 2 may be stuck into the bottom surface 114, from the viewpoint of shortening the construction period, it is preferable that it is placed on the bottom surface 114 (the bottom of the base portion 1 is in contact with the ground).

[0078] Furthermore, to explain more specifically the diameter φ1 and depth D of the base portion 1 and the thickness φ2 and height H of the pole member 2, the diameter of the base portion 1 is in the range of 0.48m or more to 1.0m or less, the depth of the base portion 1 is in the range of 1.5m to 4.0m, the thickness of the pole member 2 is in the range of 0.1m or more to 0.65m or less, and the height of the pole member 2 from the ground surface is in the range of 4m or more to 15m or less, and by using a metallic and tubular pole member 2, a balance is achieved between the effect of suppressing ground subsidence due to the pole structure 101's own weight and the effect of reducing the installation area of ​​the pole structure 101, making this a particularly suitable combination for a pole structure 101 for attaching a signboard to the tip (other end side 22) of the pole member 2.

[0079] <Concrete root wrapping materials> The concrete wrapping member 3 is placed on the base 1 and is arranged to block the through-hole 31 provided in the tubular pole member 2. Blocking the through-hole 31 makes it difficult for rainwater and the like to enter. The concrete wrapping member 3 also has the effect of preventing the pole member 2 from tipping over. 11, it is preferable that the top surface 34 of the concrete root wrapping member 3 be a surface that slopes outward from the pole member 2. Creating a sloped surface allows rainwater to flow away and makes it difficult for water to accumulate in the gap between the pole member 2 and the concrete root wrapping member 3, which has the effect of suppressing corrosion of the pole member. When the pole member 2 is a tubular member, the through-hole 31 provided in the pole member 2 is a hole for pouring the concrete member 11 into the hollow portion 33 inside the pipe, and is provided above the ground surface 91. Pouring the concrete member 11 into the hollow portion 33 of the tubular pole member 2 makes the pole member 2 less likely to tip over. Furthermore, when the tubular pole member 2 is made of metal, filling the hollow portion 33 with the concrete member 11 also has the effect of preventing rainwater from accumulating inside and causing rust inside.

[0080] <Other> Regarding the ground where the pole structure 101 is to be installed, the n value of the ground at the bottom surface 114 of the hole 111 where the bottom surface 110 of the base 1 is received is preferably 2.5 or more. Also, the n value of the ground at the bottom surface 144 of the flange groove 142 where the bottom surface 141 of the flange 14 is received is preferably 2.5 or more. If the n value is 2.5 or more, there is an effect of further suppressing the ground subsidence of the pole structure 101. The n value in this specification is a value measured by the screw weight penetration test method according to JISA1221.

[0081] <How to install the pole structure> 2 to 9, a method for installing the pole workpiece 101 will be described. As shown in Fig. 1, the pole workpiece 101 will be described as using a tubular member in which the inside of the pole member 2 is hollow (hollow portion 33).

[0082] First, as shown in Fig. 2, an auger 8 is used to dig a cylindrical hole 111 having a depth of 1.0 m to 4.5 m and a diameter of 0.4 m to 1.5 m in the ground 9. This step is referred to as a hole digging step. It is particularly preferable to use an auger 8 with a diameter (the diameter of the hole 111 after digging) of 1.0 m or more and 1.2 m or less. When an auger 8 with this diameter is used, the opening size is approximately the same as the size of a commercially available sandbag called a flexible container, so the excavated soil excavated by the auger 8 can be placed directly into the auger 8, which particularly improves the efficiency of the excavated soil removal work and is particularly effective in shortening the construction period.

[0083] Also, a groove that will become the flange 14 is created in the ground 9. Specifically, a groove is dug around the upper periphery of the hole 111 dug by the auger 8. This groove corresponds to the flange groove 142. This process is referred to as the flange groove creating process. When the hole 111 and the flange groove portion 142 are formed, the bottom surface 114 of the hole 111 and the bottom surface 144 of the flange groove portion 142 may be subjected to a rolling compaction operation.

[0084] Next, as shown in Figure 3, concrete reinforcement members 12, which are reinforcing bar members made up of rod-shaped members arranged in a lattice pattern, are installed inside the hole 111. This process is called the concrete reinforcement member installation process. At this time, by arranging the concrete reinforcement members 12 so that they are in contact with the bottom surface 114 of the hole 111 (so that the pole members 2 are in contact with the ground at the bottom of the base 1), the concrete reinforcement members 12 can be stabilized, making the work easier.

[0085] Furthermore, a flange reinforcing member 143, which is a reinforcing bar member formed by assembling rod-shaped members in a lattice pattern, is placed inside the flange groove 142. This step is referred to as a flange reinforcing member placing step. The concrete reinforcing member 12 and the flange reinforcing member 143 may be fixed to each other with a wire member called a binding wire. This step is referred to as a reinforcing member fixing step. The flange reinforcing member 143 is provided with a hole through which the pole member 2 passes at a location corresponding to the center of the cylindrical concrete reinforcing member 12 .

[0086] Next, as shown in Fig. 4, one end side 21 of the pole member 2 is placed inside the hole 111 (cylindrical concrete reinforcement member 12) so that the length (height) is 4.0 m or more and 20 m or less from the surface of the ground 9 (ground surface 91). This step is referred to as the pole member placement step. At this time, the end surface 212 of the one end side 21 of the pole member 2 and the bottom surface 114 of the hole 111 come into contact with each other.

[0087] 5 and 6, the other end 131 of the self-standing auxiliary member 13 passes through the lattice holes of the concrete reinforcing member 12 and is stuck into the ground 9, passes through the lattice holes of the concrete reinforcing member 12 and is in contact with the side wall 112 of the hole 111, or is in contact with the concrete reinforcing member 12, and one end 132 of the self-standing auxiliary member 13 is fixed to the pole member 2. This process is called the self-standing auxiliary member installation process. 1 and 6 show a state in which the other end 131 of the self-standing auxiliary member 13 passes through the lattice holes of the concrete reinforcing member 12 and is stuck into the ground 9.

[0088] Next, the concrete member 11 is poured into the hole 111 and the flange groove portion 142. As a result, the space 113 between the unevenness 116 of the side wall 112 of the hole 111 and the outer surface of the pole member 2 is filled with the concrete member 11. This process is referred to as the concrete filling process. This also brings the bottom surface 110 of the base 1 into contact with the bottom surface 114 of the hole 111, thereby supporting the weight. Furthermore, the concrete member 11 is filled into the flange groove portion 142 to form the flange groove portion 142. This step is referred to as a flange groove filling step. As a result, the bottom surface 141 of the flange portion 14 and the bottom surface 144 of the flange groove portion 142 come into contact with each other, and the weight is received.

[0089] 7, a through-hole 31 is formed in the pole member 2 at a position above the ground surface 91, spanning from the outside to the hollow internal space (hollow portion 33). This step is referred to as a through-hole forming step. Next, as shown in Fig. 8, the concrete member 11 is filled into the internal space of the pole member 2 through the through hole 31 created in the through hole creating step. This step is referred to as the step of filling the internal space of the pole with concrete.

[0090] 9, a concrete root wrapping member 3 is fabricated at a position higher than the ground surface 91 so as to hide the through-hole 31. This step is referred to as a root wrapping member fabrication step. The concrete root wrapping member 3 can be made by creating a frame 32 that surrounds the ground surface 91 side of the pole member 2, pouring the concrete member 11 into the frame 32, and removing the frame 32 after it has hardened and become fixed to the base 1, thereby completing the pole structure 101 shown in Figure 1.

[0091] In addition to the root wrapping member preparation process, a process of preparing an inclined surface before the concrete member 11 hardens may be added so that the upper surface 34 of the concrete root wrapping member 3 becomes an inclined surface, as shown in Figure 11. This process is referred to as the inclined surface preparation process. The inclined surface creating step may be a step of scraping off the concrete member 11 after it has hardened and become the concrete encasing member 3. However, from the viewpoint of shortening the construction period, it is preferable to form the concrete member 11 into an inclined surface before it hardens, rather than scraping it off after it hardens.

[0092] In this embodiment, the pole workpiece 101 having a flange portion 14 has been described, but as a modified example of this embodiment, a pole workpiece 102 without a flange portion 14 may also be used, as shown in Figure 10. Furthermore, the pole workpiece 101 of this embodiment shown in FIG. 1 and the pole workpiece 102 of the modified example of this embodiment shown in FIG. 10 do not necessarily need to be provided with the self-supporting auxiliary member 13. Furthermore, the pole workpiece 101 of this embodiment shown in FIG. 1 and the pole workpiece 102 of the modified example of this embodiment shown in FIG. 10 do not necessarily need to be provided with the concrete root wrapping member 3.

[0093] A second embodiment of the present invention will be described with reference to Fig. 12. Components having the same structure as those in the first embodiment of the present invention will be given the same reference numerals and descriptions thereof will be omitted. The pole workpiece 103 of the second embodiment is characterized in that the inside of the pole member 2 is hollow tubular, and the through hole 31 for injecting the concrete member 11 into the inside of the pole member 2 is blocked with a concrete root wrapping member 3. When pouring concrete member 11 into hollow portion 33 inside pole member 2, rainwater may enter through hole 31, causing corrosion of pole member 2. Therefore, if through hole 31 is blocked with concrete encasing member 3, blocking of through hole 31 and preparation of concrete encasing member 3 can be carried out simultaneously, which has the effect of shortening the construction period. Furthermore, by pouring concrete member 11 into the lower part of hollow portion 33 inside pole member 2, the lower part of pole member 2 becomes heavy, and pole workpiece 103 becomes stable and less likely to fall over.

[0094] In this embodiment, the base 109 only needs to have the concrete member 11, and the concrete reinforcing member 12 shown in the first embodiment may or may not be present. However, if the base 109 has the concrete reinforcing member 12, the strength of the base 109 is improved. The concrete reinforcing member 12 may be placed inside the concrete member 11, and is applicable even when the concrete reinforcing member 12 comes into contact with a side wall 112 of a hole 111 dug in the ground 9, as shown in Fig. 13. Examples of reinforcing members that come into contact with the side wall 112 of the hole 111 dug in the ground 9 include tubular members into which the pole members 2 can be placed, and the reinforcing member shown in the first embodiment, in which metal rod-shaped members are arranged in a lattice pattern. Furthermore, the shape of the base 109 in plan view is not particularly limited, but a cylindrical shape is preferable from the viewpoint of shortening the construction period, since the hole 111 can be dug with the auger 8.

[0095] <How to install the pole structure> The pole workpiece 103 of this embodiment can be installed in the same manner as in the first embodiment. Specifically, it is sufficient if the process includes a hole digging process, a pole member placement process, a concrete filling process, a through hole creation process, a pole internal space filling process, and a root wrapping member creation process. Furthermore, a modified example of the first embodiment may be applied, and a sloped surface creating step may be provided so that the concrete root wrapping member 3 has a sloped surface.

[0096] In this embodiment, as in the first embodiment, one, two, or all of the structures selected from the concrete reinforcing member 12, the flange 14, and the self-supporting auxiliary member 13 may be provided. In that case, the flange groove creating process, the concrete reinforcing member installing process, the flange reinforcing member arranging process, the reinforcing member fixing process, the self-supporting auxiliary member installing process, and the flange groove filling process are selectively performed.

[0097] A third embodiment of the present invention will be described with reference to Figures 14 and 15. Components having the same structure as in the first embodiment of the present invention will be given the same reference numerals and descriptions thereof will be omitted. The pole workpiece 104 of the third embodiment comprises a concrete reinforcing member 121 and a self-supporting auxiliary member 13, and the concrete reinforcing member 121 is characterized by comprising a self-supporting auxiliary member passing portion 122.

[0098] The self-supporting auxiliary member 13 is arranged to intersect (diagonally) in the horizontal and vertical directions, and the other end side 131 of the self-supporting auxiliary member 13 is arranged to pass through the upper self-supporting auxiliary member passing portion 122 and stick into the ground, to pass through the upper self-supporting auxiliary member passing portion 122 and contact the side of the hole 111, or to contact the upper self-supporting auxiliary member passing portion 122, thereby serving to temporarily support the pole member 2 until the concrete member 11 hardens, and helping to prevent the pole workpiece 104 from tipping over and improving its strength even after the concrete member 11 has hardened.

[0099] <<Concrete reinforcement members>> The concrete reinforcing member 121 is a cylindrical member and includes an upper self-supporting auxiliary member passing portion 122 . The upper self-supporting auxiliary member passage portion 122 consists of multiple passage portions 123 arranged in the circumferential direction so that the self-supporting auxiliary member 13 can pass through, and the passage portions 123 are through holes arranged between the internal space 124 of the concrete reinforcement member 121 and the outside. The concrete reinforcement member 121 is not particularly limited in material or shape as long as it can reinforce the base 1 (concrete member 11). For example, as shown in Figure 15, a metal cylinder or a cylindrical reinforcing bar member made of metal rod-shaped members arranged in a lattice pattern as shown in the first embodiment can be used. Furthermore, the concrete reinforcing member 121 has a height that is more than half the height of the base 1, similar to the concrete reinforcing member 12, and is approximately the same height. The concrete reinforcing member 121 is embedded in the base 1. Passing portion 123 of upper self-supporting auxiliary member passing portion 122 is provided above the center of concrete reinforcing member 121 in the up-down (height) direction.

[0100] When installing the self-supporting auxiliary member 13, as shown in Figure 16, it is necessary to install the member so that the other end 131A of the self-supporting auxiliary member 13A, shown by the dashed line, does not protrude underground from the boundary line 93 (symbol 93 shown by the dashed line) between the ground 9 of the manager's property who installs and manages the pole structure 104 and another person's property 92. Furthermore, if an obstacle 94 such as a stone is buried around the hole 111 instead of the boundary line 93, as shown in Figure 16, the other end 131A of the self-supporting auxiliary member 13A may hit the obstacle 94 and not be able to be sufficiently inserted into the ground 9. In such a case, it is possible to remove the obstacle 94 and then insert the self-standing support member 13A, but this requires time to remove the obstacle 94, which may cause a delay in the construction period. Therefore, in this embodiment, by providing multiple passing sections 123 in the circumferential direction, multiple installation directions for the self-standing auxiliary member 13 in a planar view can be selected, as shown in Figure 16 for the self-standing auxiliary members 13B to D.This has the effect of providing a wider range of options for the installation direction of the self-standing auxiliary member 13 in a planar view (for example, the directions of arrows B to D) even if the other end side 131 of the self-standing auxiliary member 13 goes beyond the boundary line 93 or an obstacle 94 is present when installing the self-standing auxiliary member 13 (improving the freedom of the direction in which the self-standing auxiliary member 13 is driven in). Furthermore, since multiple passing sections 123 are provided around the entire circumference, there is no need to install the concrete reinforcing member 121 in the hole 111 while taking into consideration the orientation of the concrete reinforcing member 121 to match the installation direction of the self-standing auxiliary member 13 in a planar view (there is no need to install the concrete reinforcing member 121 (self-standing auxiliary member passing sections 122) to match the circumferential orientation), which has the effect of shortening the construction period.

[0101] Furthermore, as shown in FIG. 14, the self-supporting auxiliary member 13 is provided above the center of the concrete reinforcing member 121, which has the effect of making it easier for the self-supporting auxiliary member 13 to be inserted into the upper part of the hole 111. 14, when the self-supporting support member 13 is stuck into the upper side (the side facing the ground 91) of the hole 111, the attachment angle θ1 (the angle between the center line 208 of the pole member 2 and the center line 138 of the self-supporting support member 13) is compared. In the comparative view shown in FIG. 17, when the self-supporting support member passing portion 122 is provided below the center and the self-supporting support member 13 is placed in a state where it is stuck into the lower side (the side facing the bottom surface 114) of the hole 111, the distance to the one end side 21 of the pole member 2 that is in contact with the bottom surface 114 of the hole 111 becomes closer, and the attachment angle θ2 (the angle between the center line 209 of the pole member 2 and the center line 139 of the self-supporting support member) becomes smaller. Therefore, in the case of FIG. 17, the pole member 2 is more likely to fall over than in the state shown in FIG. 14, and the self-supporting support member 13 needs to be stuck deeper to prevent it from falling over. Furthermore, when the self-supporting auxiliary member 13 is passed through the self-supporting auxiliary member passage portion 122 provided on the lower side, a long self-supporting auxiliary member 13 is required, which makes installation more difficult than when the member is inserted into the upper side of the hole 111, and it is also difficult to visually check that the member has been inserted, which may result in delays in the construction period.

[0102] <How to install the pole structure> The pole workpiece 104 of this embodiment can be installed in the same manner as in the first embodiment. Specifically, it is sufficient if it includes a hole digging process, a concrete reinforcing member installation process, a pole member placement process, a self-supporting support member installation process, and a concrete filling process.

[0103] In this embodiment, as in the first embodiment, one, two, or all of the structures selected from the flange 14, the concrete root-wrapping member 3, and the inclined surface of the concrete root-wrapping member may be provided. In this case, the flange groove creation process, flange reinforcing member placement process, reinforcing member fixing process, flange groove filling process, through-hole creation process, pole internal space filling process, root-wrapping member creation process, and inclined surface creation process are selectively performed. In this case, concrete reinforcing member 12 is referred to as concrete reinforcing member 121.

[0104] A fourth embodiment of the present invention will be described with reference to Fig. 18. Components having the same structure as those in the third embodiment of the present invention will be given the same reference numerals and descriptions thereof will be omitted. The pole workpiece 105 of the fourth embodiment is a modified example of the third embodiment, and is characterized by a concrete reinforcing member 1211 (self-supporting auxiliary member passing portion 1221).

[0105] The concrete reinforcing member 1211 of this embodiment differs from the concrete reinforcing member 121 of the third embodiment in that, in addition to an upper passing portion 1231 corresponding to the passing portion 123 of the concrete reinforcing member 121, it further comprises a lower passing portion 1232 located below the center in the vertical direction. The upper passing portion 1231 and the lower passing portion 1232 form the self-standing support member passing portion 1221 . As shown in Figure 18, the lower passing portion 1232 has a structure in which multiple through holes are provided in the circumferential direction, similar to the passing portion 123, and the number of through holes in the lower passing portion 1232 may be the same as or different from the number in the upper passing portion 1231, as long as there is multiple through holes. Moreover, the upper passing portion 1231 and the lower passing portion 1232 are provided at positions where the distance from the upper end of the concrete reinforcing member 1211 and the distance from the lower end of the concrete reinforcing member 1211 are substantially the same. With this structure, when installing the concrete reinforcing member 1211 in the hole 111, it is not necessary to align the top and bottom, and the construction period can be shortened. The pole workpiece 105 is installed in a state where the self-supporting auxiliary member 13 has passed through the upper passing portion 1231 of the self-supporting auxiliary member passing portion 1221.

[0106] A fifth embodiment of the present invention will be described with reference to Figures 19 and 20. Components having the same structure as in the fourth embodiment of the present invention will be given the same reference numerals and descriptions thereof will be omitted. The pole workpiece 106 of the fifth embodiment is a variation of the fourth embodiment and features a concrete reinforcing member 1211 .

[0107] The concrete reinforcement member 121 of this embodiment differs from the concrete reinforcement member 121 of the fourth embodiment in that the upper passing portion 1231 is structured such that multiple upper passing portions 1231 are provided, separated in the vertical direction, and further the lower passing portion 1232 is structured such that multiple lower passing portions 1232 are provided, separated in the vertical direction. As shown in (A) of Figure 20, the upper passing portion 1231 has a first upper passing portion 1231A which is on the end side (upper side) of the concrete reinforcement member 1211 and a second upper passing portion 1231B which is on the central side (lower side) of the concrete reinforcement member 1211 in the vertical direction. In addition, the lower passing portion 1232 has a first lower passing portion 1232A which is on the end side (lower side) of the concrete reinforcement member 1211 and a second lower passing portion 1232B which is on the central side (upper side) of the concrete reinforcement member 1211 in the vertical direction. The first upper passing portion 1231A and the first lower passing portion 1232A are provided at positions where the distance from the upper end of the concrete reinforcing member 1211 and the distance from the lower end of the concrete reinforcing member 1211 are substantially the same. Furthermore, the second upper passing portion 1231B and the second lower passing portion 1232B are provided at positions where the distance from the upper end of the concrete reinforcing member 1211 and the distance from the lower end of the concrete reinforcing member 1211 are substantially the same.

[0108] With this structure, when installing the concrete reinforcement member 1211 in the hole 111, it is not necessary to align the top and bottom, and construction time can be shortened. Furthermore, since the first upper passing portion 1231A and the second upper passing portion 1231B are provided separately on the top and bottom, the self-standing auxiliary member 13 can be installed by selecting either the first upper passing portion 1231A or the second upper passing portion 1231B, which has the effect of further improving the degree of freedom of the installation angle (in FIG. 19, the angle θ3 formed between the center line 208 and the center line 138B of the self-standing auxiliary member 13 is ≠ the angle θ4 formed between the center line 208 and the center line 138A of the self-standing auxiliary member 13). 16, even if an obstacle 94 is present, the position at which the self-standing support member 13 is inserted into the side wall 112 can be changed in the vertical direction (to the first upper passing portion 1231A or the second upper passing portion 1231B) while maintaining the installation direction of the self-standing support member 13 in a plan view. In other words, there is an effect that the attachment angle can be changed while maintaining the installation direction of the self-standing support member 13 in a plan view. The self-standing support members 13 may be provided in both the first upper passing portion 1231A and the second upper passing portion 1231B.

[0109] In this embodiment, the number of through holes (passages created in the circumferential direction) separated in the vertical direction in the upper passing portion 1231 and the number of through holes separated in the vertical direction in the lower passing portion 1232 are exemplified as two cases each and are the same number, but the numbers may be different as long as there are multiple numbers. In this embodiment, the concrete reinforcement member 1221 has been described as being formed by providing through-holes in a cylindrical metal member to form the upper passing portion 1231 and the lower passing portion 1232. However, as shown in FIG. 20(B), the concrete reinforcement member 12 may be formed by forming a cylindrical reinforcing bar member in which rod-shaped members are arranged in a lattice pattern, as in the concrete reinforcement member 12 shown in the first embodiment. In this case, the self-supporting auxiliary member passing portion 1221 corresponds to the lattice mesh. When the concrete reinforcement member 1211 is formed using a reinforcing bar member in which rod-shaped members are arranged in a lattice pattern, the reinforcing bar member can be simply bent into a cylindrical shape, which is preferable from the viewpoint of easily forming a structure having the self-supporting auxiliary member passing portions 1221 (upper passing portions 1231A-D and lower passing portions 1232A-D) throughout the entire circumferential and vertical directions. Furthermore, if the base 1 and the concrete reinforcing member 1211 are cylindrical, the holes 111 can be made more easily with the auger 8. Furthermore, when installing a plurality of self-supporting support members 13, it is easier to install them evenly from the pole member 2, which has the effect of making a more stable pole workpiece.
