Such a pole may be composed of several components such as a bottom plate, a top plate, and a pole, and these components are joined to each other by welding to complete the pole and then installed at a designated place. In addition, since the pole was made of one long rod, it was inconvenient to install and transport.

In order to improve this, Republic of Korea Registered Utility Model No. 20-0462467 discloses a technique for improving the assembly of the pole. Such a prefabricated pole has the advantage of being easy to install and transport.

However, in the conventional prefabricated pole, it is difficult to load a large amount because the configuration of the bottom plate and the top plate is a single body, and it takes time to assemble the pole because the connection is made in a screw-fastening method.

On the other hand, when an external force is applied, such as when a strong wind blows, shaking may occur. If there is such shaking, it can be a threat to safety, and when CCTV is installed, the captured image is distorted, making it difficult to take an accurate image.

Therefore, it is necessary to reinforce a method to further increase the ease of installation and transport by increasing the assemblability of each component constituting the pole, and it is necessary to consider a method for safely supporting the pole to prevent shaking due to external force.

As described above, the prefabricated pole 100 according to the embodiment of the present invention may further include a connecting member 4 capable of connecting the pole 3 in the longitudinal direction.

The connecting member 4 is a component that makes it possible to connect the short-length poles 31 and 32, and includes an extension 41, a binding portion 42, and a protrusion 43, and a reinforcing portion 44. may be further provided.

Referring to FIG. 4 , the extension part 41 forms a part of the through hole 45 and has a hollow semi-cylindrical shape. Accordingly, a cut surface S is formed in the longitudinal direction of the extension part 41 and protrudes in a bent form in the outer circumferential direction of the extension part 41 at both ends of the extension part 41 forming the cut surface S. A binding portion 42 is formed. At least one binding hole 421 through which the fastening member passes is formed in the binding part 42 .

In addition, the protrusion 43 is formed to protrude from the inner periphery of the through hole. The protrusion 43 is in contact with one end of the pole 3 to support the pole 3 . The protrusion 43 is made in a semicircular arc shape and divides the lower and upper poles 3, while contacting the upper end of the lower pole 3 and the lower end of the upper pole 3, respectively, to support the pole 3 .

The connecting members 4 made in this way are coupled so that the cut surface S and the binding portion 42 are in contact with each other to function as a complete member for connecting the pole 3 .

Referring to the drawings, the bolt is inserted into the binding hole 421 of the binding part 42 in a state where two partial members having the same shape of a semi-cylindrical shape are in contact with the cutting surface S and the binding part 42, and from the opposite side The assembly is completed by coupling the nut to the bolt. As the assembly is completed, a circular through-hole 45 is completed, and one end of the upper and lower poles 3 is coupled to the through-hole 45 .

On the other hand, the connecting member 4 has a reinforcing part 44 protruding in the outer circumferential direction of the extended part 41 in the middle of the longitudinal direction of the extended part 41 as shown, and the binding part 42 by the reinforcing part 44 is formed. ) may be a divided configuration. In this case, the portion where the divided binding part 42 and the reinforcing part 44 meet may have a form in which the binding part 42 is made thicker.

Accordingly, the connection portion of the pole 3 is strengthened by the reinforcing portion 44 , and it is possible to distribute the force applied to the binding portion 42 by the fastening member to the reinforcing portion 44 .

On the other hand, the connection member 4 may also be formed in the extension portion 41 with a hole 411 into which a fixing member for fixing the pole 3 while pressing may be inserted.

In addition, although it is illustrated in the drawing as using one connecting member 4 , a plurality of connecting members 4 may be used in consideration of the length or supporting force of the pole 3 .

In this way, by using the connecting member 4, it is possible to connect and use a plurality of short poles 3, so that it is possible to easily load the poles 3 even when there is not much space.

In the above description, the base member 1, the upper member 2, and the connecting member 4 are made of two partial members, but it is also possible to consist of a plurality of three or more partial members.

Meanwhile, the prefabricated pole 100 according to the embodiment of the present invention may further include a support member 5 connected to the base member 1 to support the pole.

Referring to FIG. 5 , the support member 5 includes a central portion 51 in which a through hole 54 is formed in the longitudinal direction, and a plurality of connecting portions 52 and connecting portions 52 extending radially from the central portion 51 . It has a closed curved surface connecting the ends and includes an outer portion 53 in which a hole 55 through which a leg member connected to the base member 1 passes is formed.

Here, the central part 51 is formed in the form of a hollow cylinder, and a through hole 54 is formed. An image signal line or an electric wire can be wired through the through hole 54, so that wiring can be performed at an accurate position.

The outer part 53 is also in the form of a hollow cylinder and forms a circular closed curved surface. A plurality of holes 55 are formed in the outer portion 53, and 8 holes are formed with reference to the drawings. The leg member 6 is coupled and fixed to this hole. The support member 5 is connected to the base member 1 by the leg member 6, but since the number of holes 55 is plural and the coupling hole 111 of the base member 1 has a slit shape, even if the position is not precisely aligned It is possible to arrange the coupling hole 111 of the base member 1 and the hole of the support member 5 to face each other. On the other hand, the other hole to which the leg member 6 is not coupled can be used as a passage for wiring an image signal line or an electric wire.

The connection part 52 connects the central part 51 and the outer part 53 to define the positions of the central part 51 and the outer part 53 while maintaining the overall structure of the support member 5 . In the drawings, the connecting portion 52 is illustrated as being composed of four connecting bars, but the number of connecting bars may be appropriately modified and employed.

The support member 5 configured as described above may be firmly coupled to the base member 1 via the leg member 6 , and thus the pole may be more firmly supported. In addition, the support member 5 of the above type has the advantage of being easily manufactured in the form of extruding or injecting a synthetic resin to manufacture a base material formed in a long cylindrical shape while having the cross-sectional shape as described above and cutting it.

Meanwhile, the support member 5 can be manufactured in a form in which a through space V is formed between the holes 55 of the outer part 53 as shown in FIG. 7 . In the case of manufacturing in this way, since the basic structure is the same, the material can be saved as much as the through space while maintaining the supporting function, which is advantageous in terms of economy. Meanwhile, in the support member 5 , a thread may be formed in the hole 55 through which the leg member 6 passes.

Hereinafter, a form of supporting the base member 1 using the support member 5 will be described in detail with reference to the drawings.

In order to connect and fix the support member 5 and the base member 1, the leg member 6 in the form of a rod may be used. The leg member 6 may have one end bent and extended. One end of the extending leg member 6 passes through the hole 55 of the support member 5 and the coupling hole 111 of the base member 1 in sequence. The leg member 6 is formed with a screw thread, and a nut is fastened to the screw thread to be fixed to the support member 5 and the base member 1 .

An example of a form using the support member 5 will be described with reference to FIG. 6 . Referring to the drawings, after excavating the bottom surface, the supporting member 5 to which the leg member 6 is coupled is horizontally installed and installed underground. At this time, a wiring pipe (P) for wiring an image signal line or an electric wire is pulled out through the through hole 54 of the support member 5 . The central portion 51 in which the through hole 54 is formed may serve to guide the wiring position.

Thereafter, a base (B) made of concrete is formed. Accordingly, the supporting member 5 and the leg member 6 are fixedly arranged on the base, and the end of the leg member 6 protrudes above the base B. The base (B) can be formed by pouring concrete into the formwork and hardening in a state in which the wiring pipe (P) of the video signal line or electric wire, the leg member (6), and the supporting member (5) are arranged on the base-shaped formwork. . Thereafter, the base member 1 may be coupled to the end of the leg member 6 protruding above the base B to be fixed.

In this way, it is possible to stably support the prefabricated pole 100 using the support member 5 and to facilitate wiring of an electric wire or an image signal line.

As described above, each of the components of the prefabricated pole 100 according to the embodiment of the present invention is not joined by welding, but can be assembled simply by fitting and fastening such as bolts and nuts, and each component is made by combining partial members. Easy to install and transport.

On the other hand, it is preferable that the components (base member 1, upper member 2, pole 3, connection member 4, etc.) of the prefabricated pole 100, which are the above-described components, are made of an insulator. Generally applicable insulators include plastics including polyvinyl chloride (PVC) and fiber-reinforced plastics (FRP).

Conventionally, a pole was manufactured using a metal material for strength, etc., but this was not preferable because there is a risk of electric leakage and electric shock. As in the present invention, if PVC or the like is used as a material and the thickness is higher than a certain level, problems such as electric leakage and electric shock, which are problems in existing poles, can be solved, and a pole excellent in strength can be manufactured. .

In addition, when the component is made of PVC or fiber-reinforced plastic, there is an advantage that poles of various colors can be manufactured. In the case of a metallic material, since the coating applied to the surface may peel off, it is aesthetically advantageous to use a color similar to that of the metallic material.

However, in the case of PVC, fiber-reinforced plastic, etc., since the material itself can have a desired color without the need for overcoating on the material, even if the surface is damaged by an external impact, there is no change in color.

Therefore, when using PVC, etc. as in the present invention, it is possible to manufacture poles using various colors without worrying about the color peeling off.

Prefabricated poles as described above are not limited to the configuration and method of the above-described embodiments, but may be configured by selectively combining all or part of each embodiment so that various modifications can be made. .

Although the detailed description of the present invention described above has been described with reference to a preferred embodiment of the present invention, those skilled in the art or those having ordinary knowledge in the art will have the spirit of the present invention described in the claims to be described later. And it will be understood that the present invention can be variously modified and changed without departing from the technical field.
