[0004] However, the type of equipment that combines the ground line rod (3) and the ground line root (7), washer (8), and two nuts (9) through the lower part of the ground line rod (3) can only be applied to ground line construction sites, but construction was impossible in mountainous areas (rocky areas) and roadside concrete structures because the type of equipment is not suitable.

[0005] That is, when there are difficult places to construct a guy line (rocky areas, concrete retaining walls, etc.) after the construction of angles and anchor posts, the guy line construction is absolutely necessary at angle posts and anchor posts due to concerns about pole inclination, but since construction is impossible with the conventional guy line rod (3) equipment form, the guy line rod (3) is cut and bent arbitrarily before construction is carried out, so the construction method is not standardized, making it difficult to improve quality, and there was a problem of construction defects occurring as well as construction time being long.

[0020] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 3 to 8, in order to fully understand the present invention. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. It should be noted that in each drawing, identical components may be illustrated with the same reference numerals. Detailed descriptions of known functions and components that are deemed to unnecessarily obscure the essence of the present invention are omitted.

[0021] Referring to FIGS. 3 to 7, the anchor bolt type guy line rod (90) of the present invention is fixed to a drilled hole (200) in a rock or concrete retaining wall and supports a utility pole connected by a guy line, and is composed of an anchor bolt (100), a sleeve (110), a nut (120), a flat washer (130), a spring washer (140), an eye nut (150), a guy line connecting ring (160), and a punching machine (210).

[0022] That is, the anchor bolt (100) is inserted into the drilled hole (200), and the lower part of the anchor bolt (100) is hooked with the lower part of the sleeve (110) and is formed with an expansion portion (102) that gradually widens from a certain height downwards so that it opens up upon impact, and the upper part of the anchor bolt (100) has a male screw portion (104) that is fastened with an eye nut (150).

[0023] The sleeve (110) has an insertion hole (112) formed therein so that an anchor bolt (100) can be inserted, and the lower part of the sleeve (110) has a cut portion (114) formed at a certain height of the sleeve (110) that is opened downward so that when struck by a punching machine (210), it slides down along the expansion portion (102) and spreads out or is crushed to be secured to the inner circumference of the drilled hole (200) to secure the anchor bolt (100).

[0024] At this time, it is preferable that a plurality of the above-mentioned incisions (114) be formed at regular intervals on the lower circumference side of the sleeve (110).

[0025] The above nut (120) is fastened to the male threaded portion (104) of the anchor bolt (100), and when the male threaded portion (104) of the anchor bolt (100) and the female threaded portion (154) of the eye nut (150) are fastened, it comes into close contact with the body (152) of the eye nut (150), thereby increasing the bonding strength.

[0026] The flat washer (130) and spring washer (140) are first fitted into the male threaded portion (104) of the anchor bolt (100) and serve to increase the bonding strength of the nut (120) so that the eye nut (150) does not come loose from the anchor bolt (100).

[0027] The above eye nut (150) has a female screw portion (154) formed in the lower center of the body (152), a ring portion (158) connected to a branch line connecting ring (160) formed in the upper part of the body (152), and an anti-loosening projection (156) formed between the female screw portion (154) in the center of the lower side of the body (152) and the lower edge side.

[0028] At this time, the above anti-loosening protrusions (156) are formed in multiple numbers at regular intervals along the lower circumference of the eye nut (150), and serve to prevent the nut (120) from loosening by increasing the contact force between the eye nut (150) and the spring washer (140).

[0029] The above-mentioned guy wire connecting ring (160) is made of a metal or insulating material that is connected to move along the loop portion (158) of the eye nut (150) and serves to be fixed to the lower part of the guy wire (wire) by a clamp. That is, the guy wire connecting ring (160) moves along the loop portion (158) when vibration of the guy wire occurs and dampens the vibration, thereby preventing damage caused by friction that may occur intensively at the part where the loop portion (158) and the guy wire are directly connected and come into contact (the part that cannot move and is connected in only one place).

[0030] The above punching machine (210) is positioned so as to be in vertical contact with the top of the sleeve (110) within the perforation hole (200), and when struck with a hammer or the like, the sleeve (110) descends along the anchor bolt (100), causing the lower part of the sleeve (110) to be spread open or deformed.

[0031] At this time, it is preferable that the above punching machine (210) be composed of a hollow tube with a lower outer diameter smaller than the upper outer diameter.

[0032] Referring to FIG. 8, the method for constructing an anchor bolt type guy rod of the present invention involves drilling into a rock or concrete retaining wall to form a hole (200), and then inserting an anchor bolt (100) fitted with a sleeve (110) into the hole (200).

[0033] Next, the sleeve (110) is struck by a punching machine (210) so that the sleeve (110) extends from the anchor bolt (100) within the hole (200) and is secured to the hole (200) while gripping the anchor bolt (100).

[0034] At this time, a resin (300) made of epoxy resin is injected into the space between the hole (200) and the sleeve (110) to prevent moisture from penetrating into the hole (200).

[0035] Next, a nut (120), a flat washer (130), and a spring washer (140) are fitted in sequence onto the male threaded portion (104) of the anchor bolt (100) protruding outside the drilled hole (200), and then a final eye nut (150) is fastened.

[0036] Next, the lower part of the branch wire is wound around the branch wire connecting ring (160) connected to the loop portion (158) of the eye nut (150), and then the branch wire is secured by a clamp so that it does not come undone, thereby completing the installation of the branch wire rod (90).

[0037] As such, the present invention is composed of an anchor bolt type guy line rod structure and a construction method thereof, wherein a hole (200) is formed in the ground, such as in a cut area of ​​a rocky region or a concrete retaining wall along a roadside, and the anchor bolt (100) inside the hole (200) is secured by shape deformation caused by striking of a sleeve (110), and the anchor bolt (100) and an eye nut (150) are connected, and the guy line connecting ring (160) connected to the eye nut (150) is connected to the utility pole as a guy line. Therefore, by standardizing the guy line construction standards, not only can quality be improved, but construction convenience and stability can also be secured, and construction time can be shortened.

[0038] Meanwhile, the present invention is not limited to the embodiments described above, but can be implemented with modifications and variations within the scope of the essence of the invention, and such technical concepts to which modifications and variations are applied should also be considered to fall within the scope of the following patent claims.
