Description

  The present invention relates to a utility pole for preventing a utility pole from tilting or falling.

  Conventionally, cables such as power transmission lines and telephone lines are bridged between utility poles installed at predetermined intervals in a tensioned state. For this reason, in addition to the tension of the cable and the tension of the cable, an overturning moment is generated in the utility pole due to the influence of the tension generated on the cable when a wind pressure load acts on the cable. As a result, the utility pole may tilt or fall in the direction in which the overturning moment acts.

  Under such circumstances, utility poles for preventing the utility pole from tilting or falling are provided. Such a pole for a power pole is formed in a column shape with a steel pipe, concrete, or the like, and includes a pole body having rigidity in the longitudinal direction. The column main body has a first end in the longitudinal direction and a second end opposite to the first end. And the cross-sectional shape of the support | pillar main body is formed uniformly from the 1st end part to the 2nd end part.

  The first end of the column main body is connected to the upper portion of the utility pole. On the other hand, the second end side of the column main body is buried in the ground at a predetermined distance from the utility pole in the direction in which the overturning moment acts. Thereby, a support | pillar main body is installed with the attitude | position inclined with respect to the utility pole.

  And since the column main body has rigidity in the longitudinal direction, the second end is supported by the ground, and even if the axial pushing force acts due to the influence of the overturning moment acting on the utility pole, It can counter the overturning moment acting on the utility pole.

  Accordingly, the utility pole support having the above-described configuration can prevent the utility pole from tilting or falling in the direction affected by the cable tension (the direction in which the falling moment acts) (for example, Patent Document 1). reference).

JP 2011-111769 A

  By the way, the cable supported by the utility pole is not limited to one, and may be supported by the utility pole so that two or more cables extend in different directions. Therefore, a falling moment may act on the utility pole in different directions due to the influence of the tension of a plurality of cables. In such a case, it is necessary to install utility poles corresponding to each direction in which the overturning moment acts.

  However, since the second end of the utility pole is embedded in a position away from the utility pole in the direction in which the overturning moment acts, to install the utility pole in correspondence with each direction in which the fall moment acts A space of a predetermined area is required around the utility pole.

  Therefore, depending on the installation conditions of the utility pole (for example, when the utility pole is installed in the vicinity of the building), the space required for installation of the utility pole cannot be secured, and the utility pole is installed in all positions corresponding to the falling moment. It may not be possible to install a column. In such a case, if a falling moment acts on the opposite side of the utility pole to the side where the utility pole is installed, an axial pulling force acts on the pole body of the installed utility pole. Become.

  As described above, the pole for the power pole is configured to have the same cross-sectional shape from the first end to the second end of the pole body. The frictional resistance generated between the two is small. For this reason, the pole for a power pole tends to be pulled out when an axial pulling force acts on the pole main body, and it may not be possible to prevent the pole from tilting in the direction in which the overturning moment acts.

  Therefore, in view of such a situation, the present invention is for a utility pole that can prevent the utility pole from tilting without providing another utility pole support corresponding to the overturning moment acting on the side opposite to the installation position with respect to the utility pole. It is an object to provide a support.

  The pole for a power pole according to the present invention includes a pole body that is formed in a column shape and has rigidity in the longitudinal direction. The pole body includes a first end and a second end opposite to the first end. The first end is connected to the power pole supporting the cable, and the second end is embedded in a position away from the power pole by a predetermined distance and supported by the ground, thereby being inclined with respect to the power pole. The power pole pole installed at the power pole is connected to the second end of the pole body, and at least a portion extends radially outward from the outermost periphery of the second end of the pole body. An anchor portion is provided.

  If a falling moment acts on the side of the utility pole connected to the pole main body due to the influence of the cable tension, the pole main body receives an axial pushing force from the utility pole. However, the column main body is rigid in the longitudinal direction, and the second end of the column main body is supported by the ground by being embedded at a position away from the utility pole. It resists the overturning moment acting on the utility pole without decreasing. Therefore, the utility pole can prevent the utility pole from falling to the side where the utility pole body is connected.

  In addition, when a falling moment acts on the side of the utility pole opposite to the side to which the pole body is connected due to the influence of the cable tension, the pole body receives an axial pulling force from the utility pole. However, the anchor portion is connected to the second end portion of the column body and at least a part thereof is configured to extend radially outward from the outermost peripheral portion of the second end portion of the column body. When an axial pulling force acts on the main body, the drag against the pulling force is applied by being caught on the ground.

  As a result, the pole for power poles resists overturning moments acting on the side opposite to the side where the pole pole body is connected without being pulled out of the ground even if an axial pulling force acts on the pole body. To do. Therefore, the utility pole can prevent the utility pole from falling to the side opposite to the side where the utility pole body is connected.

  As one aspect of the present invention, the anchor portion includes a flat plate-shaped or curved plate-shaped anchor main body, and the anchor main body is provided directly or indirectly on the end surface on the second end side of the column main body and has an outer diameter. Is preferably set to be larger than the outer diameter of the second end of the column main body.

  In this way, the anchor body has a large area in contact with the ground. For this reason, the anchor main body has a larger area to be caught on the ground when an axial pulling force is applied to the column main body, and a larger drag can be applied to the pulling force. As a result, the anchor portion can more reliably prevent the column main body from being pulled out by the axial pulling force acting on the column main body.

  In this case, it is preferable that the anchor main body is formed such that the outer peripheral portion is displaced toward the first end portion side of the column main body rather than the central portion.

  In this way, the anchor body is easily caught on the ground. In addition, the anchor body can efficiently receive earth pressure from the ground. Therefore, even if the anchor body has an axial pulling force acting on the column main body, it is possible to apply a greater resistance against the pulling force. As a result, the anchor portion can more reliably prevent the column main body from being pulled out by the axial pulling force acting on the column main body.

  As another aspect of the present invention, the anchor portion includes a connection portion for connecting the anchor main body to the end surface on the second end side of the column main body, and the connection portion is concentric with the second end portion of the column main body. Even if the connection part main body is provided directly or indirectly on the end face on the second end side of the column main body, the outer diameter of the connection unit main body is set smaller than the outer diameter of the second end of the column main body Good.

  If it does in this way, an anchor main body will reduce the area which contacts a connection part. Therefore, when the anchor main body is embedded, the area in contact with the ground is increased. As a result, the anchor body has a larger area to be caught on the ground when an axial pulling force is applied to the column main body, and a larger drag can be applied to the pulling force. Therefore, the anchor portion can more reliably prevent the column main body from being pulled out by an axial pulling force acting on the column main body.

  As another aspect of the present invention, the connection portion may include a joint portion into which the second end portion of the column main body can be fitted and removed, and the connection portion main body may be configured to extend from the joint portion. If it does in this way, since the support | pillar for electric poles can remove an anchor part from a support | pillar main body, it can carry and store easily. In addition, according to the state of the ground in which the second end of the pole main body is embedded, the pole for the power pole can connect the anchor main body having a size suitable for the state of the ground to the second end of the pole main body. .

  As described above, the utility pole according to the present invention can prevent the utility pole from tilting without providing another utility pole support corresponding to the overturning moment acting on the opposite side of the installation position with respect to the utility pole. An excellent effect of being able to do so can be achieved.

  The column main body 2 installed in the above manner receives an axial pushing force from the utility pole D when a falling moment acts on the side of the utility pole D connected to the pole main body 2 due to the influence of the tension of the cable C. become. However, the column main body 2 has rigidity in the longitudinal direction, and the second end P2 of the column main body 2 is supported by the ground by being embedded at a position away from the utility pole D. The end portion P2 (the outer surface of the anchor main body 30) opposes the overturning moment acting on the utility pole D without being reduced to the ground. Therefore, the utility pole 1 can prevent the utility pole D from falling to the side where the utility pole body 2 is connected.

  Further, when the pole body 2 installed in the above-described manner is subjected to an overturning moment on the side opposite to the side to which the pole body 2 of the utility pole D is connected due to the influence of the tension of the cable C, the pole body 2 is axially moved from the utility pole D.

An excellent effect of being able to prevent tilting can be achieved.

  Moreover, since the outer diameter of the anchor main body 30 according to the present embodiment is set to be larger than the outer diameter on the second end P2 side of the column main body 2, when an axial pulling force acts on the column main body 2 In addition, the area that is caught on the ground becomes wider, and a greater resistance can be applied to the pulling force.

  Furthermore, since the anchor body 30 is formed so that the outer peripheral portion is displaced toward the first end portion P1 side of the column main body 2 from the center portion, the ground when the axial pulling force acts on the column main body 2 It becomes easy to get caught in. Further, the anchor body 30 can efficiently receive earth pressure from the ground. Therefore, even if an axial pulling force acts on the column main body 2, the anchor main body 30 can apply a larger drag force against the pulling force.

  Therefore, the utility pole 1 can be more reliably prevented from being pulled out by the axial pulling force acting on the pole body 2.

Since the part P <b> 2 is connected to the utility pole D by the connecting member 4, the part P <b> 2 is installed in an inclined posture with respect to the utility pole D.

  Therefore, the column main body 2 installed in the above-described manner has an indentation force in the axial direction from the electric pole D when a falling moment acts on the side of the electric pole D to which the column main body 2 is connected due to the influence of the tension of the cable C. Even if it receives, it opposes the falling moment which acts on the utility pole D. Therefore, the utility pole 1 can prevent the utility pole D from falling to the side where the utility pole body 2 is connected. Thereby, the pole 1 for a utility pole can prevent the utility pole D from falling to the side where the pole body 2 is connected.

  Further, the column main body 2 installed in the above-described manner is arranged so that the overturning moment acts on the side opposite to the side where the column main body 2 is connected to the electric pole D due to the influence of the tension of the cable C. Even when the pulling force in the direction is received, the anchor portion 3 is hooked on the ground, so that a drag force against the pulling force is applied. As a result, the utility pole 1 can prevent the utility pole D from falling on the side opposite to the side where the utility pole D is connected to the utility pole D.

  As described above, according to the utility pole post 1 according to the present embodiment, the utility pole D can be provided without providing another utility pole support 1 corresponding to the overturning moment acting on the side opposite to the installation position with respect to the utility pole D. An excellent effect of being able to prevent tilting can be achieved.
