Description

  This device is used when various types of cables for electric power, communication, and other power are raised from the ground to a pillar such as a concrete pillar arranged corresponding to a customer and wired. The present invention relates to a rising wiring protective conduit device for cables which can be protected and accommodated in a state in which a plurality of free tubes such as a metal flexible tube which collectively accommodates these various cables are integrated.

Conventionally, when various types of cables for power, communication, etc. are raised from the underground conduit to the ground and wired, for example, disposed on the side of the column made of concrete, for example, standing at the startup position Cables are protected by being inserted into a riser member made of steel pipe. In other words, the cable is set up and wired through a riser pipe member fixed to the column surface through a flexible pipe such as a metal flexible pipe connected to the underground pipe line and fixed to the post surface. Branch wiring is done for each house, or it is drawn into various facilities of a predetermined consumer. At this time, the rising pipe member is individually arranged on the side of the support column corresponding to the starting position of various cables for power, communication, etc., and each dedicated rising pipe corresponding to each individual universal pipe is used. It becomes the structure wired through each pipe member. When the cables are maintained by an electric power company, a communication company, etc., the electric power company, the communication company, etc., perform maintenance work for each riser member corresponding to these various cables for electric power and communication.
nothing special

  However, in such a conventional cable rising line protection conduit device, the rising pipe members are individually arranged on the side surfaces of the support columns corresponding to the rising positions of various cables for power, communication, etc. For this reason, a plurality of pieces are installed around the support column, and the appearance around the support column is deteriorated. Moreover, in order to improve the appearance, when only one riser member is laid on one strut, for example, when it is necessary to increase the number of wires to the same consumer at a later date, the same Since it is inconvenient to install another rising pipe member on the column, it is inconvenient to install the rising tube member on another column that is located away from the conventional column close to the customer. Then, various cables are routed with an extra length, which is extremely useless. Also, during maintenance of cables, electric power companies, communication companies, etc., for each rise pipe member individually arranged on the side of the support column corresponding to the startup positions of these various cables for power, communication, etc. Since maintenance work is performed, it is difficult to collectively manage various cables at a fixed location around the support column.

  Therefore, the present invention has been devised in view of the existing circumstances as described above. For example, a plurality of free pipes each accommodating a plurality of various cables to be wired corresponding to a consumer are provided. It is possible to consolidate and store and wire it into a single riser pipe member, and it is possible to collectively manage a plurality of cables at a certain location around the installed struts. In addition, it is an object of the present invention to provide a rising-wiring protection conduit device for cables that does not impair the appearance around the column.

In order to solve the above-described problem, in the present invention, a wiring conduit that accommodates and protects the cables C that are wired and fixed along the height direction of the support column P is formed on the surface of the provided support column P. A plurality of flexible tubes F through which various cables C for power and communication drawn out to the ground corresponding to the pillars P are respectively inserted can be connected via a cylindrical bushing 7. The joint means Q that is connected to the joint P to be fixed to the surface of the support P so as to form a rising wiring pipeline, and the various cables C can be aggregated and fixed along the surface of the support P. And a pipe member 1.
Further, the joint means Q is inserted into the lower end opening of the riser pipe member 1, and the one end side of the circumferential surface bulges radially in the downward direction from the connection cylindrical part 4 </ b> A and expands into a substantially trumpet shape. A plurality of hole portions 5A in which the cover body 4 made up of each of the aggregated cylindrical portions 4B and the plurality of flexible tubes F that can be bent are individually communicated, and the flexible tubes F can be fixed by screwing the bushing 7. And a lid portion 5 that is closed and fixed to the lower end opening of the cover body 4.
The joint means Q can be disposed in the ground G region, or can be buried in the ground and connected to the rising pipe member 1 via the underground guide pipe R.

In the rising wiring protection conduit device for cables according to the present invention configured as described above, the joint means Q is connected to the rising pipe member 1 for wiring protection fixed to the support P surface so as to be a flexible pipe. A plurality of individual metal flexible tubes, which are F, can be connected together, whereby a single riser member 1 as a housing member tube of the plurality of cables C in the wiring construction method of the cables C can be connected. Make it possible to fully support consolidation.
At the time of closing and fixing the lid portion 5 with respect to the aggregate cylindrical portion 4B in the joint means Q at this time, one end opening portion side of the universal tube F is engaged with one side of the hole portion 5A of the lid portion 5 or inserted. After that, the bushing 7 is screwed into the spiral inner peripheral groove surface of the flexible tube F from the opposite side of the hole 5A to fix the flexible tube F to the lid 5 and the aggregated cylindrical portion of the cover body 4 By fixing the lid portion 5 to 4B, the concentrated wiring work of the various cables C through the joint means Q to the riser member 1 is efficiently performed.
Further, the cylindrical bushing 7 screwed into the universal tube F facilitates the attachment of the universal tube F to the joint means Q and prevents the universal pipe F from coming out of the joint means Q.
The joint means Q in the ground G part is easily disassembled at the time of moving the support column P accompanying the change of the starting position, and makes it easy to take out the cables C and reattach them at the transfer destination. The underground buried joint means Q is not affected by the ground G as an aggregation point of the plurality of cables C and reliably protects them.

  Since the present invention is configured as described above, it is possible to collectively manage various cables C at a fixed location around the support column P, and the appearance around the support column P is not impaired. In the wiring construction method of the cables C, it is possible to sufficiently cope with the unification of the plurality of free pipes F accommodating the various cables C with respect to the one rising pipe member 1. In addition, various types of cables C are collected for each consumer, and it is possible to quickly cope with changes in the number of wires according to the respective demands of each consumer.

  That is, this design is to form a wiring conduit for storing and protecting the cables C fixed and wired along the height direction of the support P on the surface of the support P.

As a result, it is possible to collectively manage various cables C at a fixed location around the support column P.

  In addition, since a plurality of free pipes F can be connected to one centralized riser member 1, each of the free pipes F can be used individually by a cable laying company, a communication company, etc. It also makes it easier to manage. In addition, for example, when various cables C from manholes or the like are increased corresponding to the customer, when the drawer P is laid through the flexible tube F by fixing the wiring to each column P, the existing column P If the rising pipe member 1 is laid, a plurality of free pipes F can be connected and fixed to the existing one rising pipe member 1 by the joint means Q. Therefore, there is an advantage that unnecessary wiring and unnecessary wiring of the cables C can be eliminated. Furthermore, the rising wiring protection conduit device itself of the cables C that does not impair the appearance around the column P can be manufactured easily and with good workability.

  In addition, various cables C are formed by collecting a plurality of individual flexible metal pipes, which are free pipes F, with respect to the rising pipe member 1 for wiring protection fixed to the support P surface to form a rising wiring pipe line. Since each wiring is made via the connecting means Q that can be connected, a plurality of individual rising pipe members 1 corresponding to each individual flexible pipe F can be laid as in the prior art, or struts located at separate positions. There is no need to lay and connect the riser pipe member 1 to the P, and the state is unified by a single riser pipe member 1 that collects and accommodates a plurality of cables C in the cable wiring method. It will be possible to respond sufficiently.

  Since the universal pipe F is connected and fixed to the joint means Q via a cylindrical bushing 7 that is screwed into the universal pipe F, the flexible pipe F can be easily attached to or detached from the joint means Q. In addition, it is possible to reliably prevent the free pipe F from coming out of the joint means Q.

  Further, the joint means Q is inserted into the lower end opening of the riser pipe member 1, and the one end side of the circumferential surface bulges radially in the downward direction from the connection cylindrical part 4 </ b> A and expands into a substantially trumpet shape. A plurality of hole portions 5A in which the cover body 4 made up of each of the aggregated cylindrical portions 4B and the plurality of flexible tubes F that can be bent are individually communicated, and the flexible tubes F can be fixed by screwing the bushing 7. And the lid portion 5 that is closed and fixed to the lower end opening of the cover body 4, so that various kinds of housings accommodated in a plurality of free tubes F through joint means Q for the rising pipe member 1 are used. Wiring work in which the cables C are aggregated can be efficiently performed.

  Furthermore, by disposing the joint means Q on the ground G site, it is not necessary to excavate the site P when the column P is moved due to the change of the starting position. In addition, it is not necessary to notify the government offices for construction permission, and can respond quickly. Further, since the work is performed on the ground surface, it is easy and simple to take out the cables C and reattach them at the transfer destination, and the work load is small.

  On the other hand, by burying the joint means Q in the ground and connecting it to the riser pipe member 1 through the underground guide pipe R, there is no influence on the ground G as an aggregation point of a plurality of cables C, and it is ensured. This can be protected.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. A reference symbol P shown in the drawing draws cables C from underground conduits to necessary places such as power, communication, and other power in consumers. For this purpose, for example, a column made of concrete is used as a support. And, for example, three flexible pipes F each of which is formed by a rising pipe member 1 etc. made of, for example, a steel material fixed to the column P and accommodates a plurality of cables C to be raised. Are integrated by a joint means Q, which will be described later, so that they are communicated with each other in one rise pipe member 1 and various cables C are collectively protected. In the present embodiment, the riser pipe member 1 protects various cables C such as power, communication, and other powers. However, the present invention is not limited to this, and two or four or more free pipes F are provided. Of course, the joint means Q itself may be changed so as to be able to cope.

  As shown in FIG. 1, the riser member 1 is fixed to the support column P by tightening the fixing band 2 surrounding the support column P at an appropriate interval in the vertical direction. The fixing band 2 itself is a known one that has been used in the past, and is a tightened state that is pulled by screwing an engaging portion that engages with any of a plurality of through holes that are opened in the band body. This surrounds the column P.

  The riser pipe member 1 has a substantially circular cross section and forms a tubular conduit as a whole. The riser pipe member 1 itself has a wiring amount of various cables C to be inserted and supported in a risen state. However, the present invention is not limited to this. For example, it may have any shape such as a triangle, rectangle, or ellipse. It can also be formed.

  Further, a waterproof cap 3 that closes and covers the upper opening of the wiring conduit formed by the rising pipe member 1 fixed to the column P is detachably attached to the upper end of the rising pipe member 1. The waterproof cap 3 is formed by integrally connecting a fitting portion 3A fitted to the upper end of the riser member 1 and a cone-shaped lid portion 3B that gradually narrows as it reaches the upper end. It is made of synthetic resin, soft rubber or the like. The fitting portion 3A has a cross-sectional shape corresponding to the cross-sectional shape of the above-described wiring conduit, for example, a flat, circular outer shape, and a flat groove-shaped rising pipe member 1 in which the upper end edge of the rising pipe member 1 is fitted. A loop-like insertion groove 3C in which a plurality of groove portions are continuously formed is formed on the bottom surface. The lid 3B itself is formed in a step shape having a plurality of step portions corresponding to different opening diameters so that a cutting opening diameter can be selected corresponding to the amount of wiring going out from the inside of the conduit. It is assumed that it is cut and opened with a cutter tool or the like at the position of the step.

The lid 5 is formed by opening and closing the lower end opening of the cover body 4. For example, three nuts 6 are fixed to the inner peripheral surface of the opening edge portion of the aggregate cylindrical portion 4B of the cover body 4 by welding or the like toward the inner diameter direction. Three bolt insertion holes 5B are formed so as to face the six positions.

  At the time of closing and fixing the lid portion 5 to the aggregated cylindrical portion 4B, the one end opening side of the universal tube F is engaged with or inserted into one side of the hole portion 5A of the lid portion 5 or inserted. From the opposite side of the hole 5A, for example, a bell mouth type bushing 7 is screwed into the spiral inner peripheral groove surface of the free tube F to fix the free tube F to the cover 5, and then the cover 5 is covered. The lid 5 is fixed to the aggregated cylindrical part 4B of the cover body 4 by screwing the mounting bolt 8 into the bolt insertion hole 5B after the bolt insertion hole 5B of the lid part 5 is brought into contact with the nut 6 at the nut 6 position. Is to be done.

  The bushing 7 itself is a well-known one that has been used conventionally. For example, the bushing 7 has a diameter larger than that of the hole portion 5A of the lid portion 5 on one end opening side of the cylindrical body inserted into the universal tube F. A locking flange portion 7A for locking to the inner peripheral edge portion of the hole portion 5A is formed, and on the other end opening edge end side of the cylindrical body, it should correspond to the spiral inner peripheral groove surface shape of the universal tube F. A male threaded portion for engagement, which is notched in a spiral shape through a U-shaped recess 7C and is bent in an oblique direction to the outer diameter so as to be screwed into the spiral inner peripheral groove of the universal tube F. 7B is formed.

  A pair of left and right sides formed by forming a rod-like bar shape into a handle shape at a substantially intermediate position along the connecting cylindrical portion 4A on the opposite side of the bulging direction of the collective cylindrical portion 4B of the cover body 4. The fixed frame 2 for inserting the fixed band 2 is fixed by welding or the like. The fixed band 2 surrounding the support P is inserted into the fixed frame portion 9 and then the fixed band 2 itself is tightened to cover the cover body 4. It itself is fixed to the column P.

  Note that the rising wiring protection conduit device for the cables C according to the present embodiment takes out the various cables C in the interior by disassembling the column P when the column P is moved along with the change of the rising position. The cable C may be accommodated by being mounted again on the post P. At the time of disassembly, the joint means Q can be easily disassembled from the riser pipe member 1 by being exposed to the ground surface and being fitted in the lower end of the riser pipe member 1 as shown in the figure. You can connect again.
