Description

Electrical construction method for rail structure using Full Threaded Bolt

The present invention relates to an electrical work method for a rail structure using a computer bolt.

Power lines for supplying electricity to buildings or apartment complexes have weak coverings and bend freely, so a wire protection tube made of synthetic resin or steel is fixed to a ceiling-mounted bolt using a fixing device and then installed inside the wire protection tube.

Such prior art technology includes Korean Patent Publication No. 10-2024544 (Title of invention: Apartment complex wire protection pipe fixing device).

However, in the past, when connecting a wire protection tube to a bolt, there was a problem that the bracket was not safely supported by the bolt, the bracket was easily detached from the bolt, and the wire protection tube was easily damaged due to direct contact between the wire protection tube and the bolt.

In addition, due to the fixing method using a fixed bolt, the position of the wire protection tube is easily changed, and when an external force is applied to the bracket from below, the bracket and the hanging bolt are easily damaged.

Republic of Korea Patent Publication No. 10-2024544 Republic of Korea Patent Publication No. 10-2444515

The present invention has been made to solve the above-mentioned conventional problems, and its purpose is to provide an electrical work method for a rail structure using a computer bolt that is easy to fix and install.

The present invention provides an electrical work method for a rail structure using a computer bolt, including: a step (S10) of installing an anchor bolt (110) on a ceiling; after step S10, a step (S20) of assembling a computer bolt (120) to the anchor bolt (110); after step S20, a step (S30) of assembling a rail assembly (200) to a hanging bracket (130) arranged at the bottom of the computer bolt (120); after step S30, a step (S40) of assembling an electrical product to the rail assembly (200); a step (S50) of temporarily fixing a cable holder (400) to an outer surface of the computer bolt (120); after step S50, a step (S60) of installing a cable (50) to the cable holder (400); after step S60, a step (S70) of fixing the cable holder (400) with a clip (430).

The above rail assembly (200) includes a rail housing (250) arranged to intersect the computer bolt (120) at the lower end of the computer bolt (120); a first electrode housing (210) arranged on one side of the inside of the rail housing (250); and a second electrode housing (220) arranged on the other side of the inside of the rail housing (250) and facing the first electrode housing (210). In the S50 step, the cable holder (400) can be temporarily fixed to the upper side of the rail housing (250).

The cable holder (400) includes a first holder (410) formed to wrap around one side of the outer surface of the computer bolt (120) and to form a mutual engagement with the computer bolt (120) in the vertical direction; a second holder (420) assembled to rotate relative to the first holder (410), formed to wrap around the other side of the outer surface of the computer bolt (120), and to form a mutual engagement with the computer bolt (120) in the vertical direction; and in the step S50, the first holder (410) and the second holder (420) can form a mutual engagement with the outer surface of the computer bolt (120) in the vertical direction.

The first clip-catching portion (433) and the first clip home form mutual engagement in the horizontal direction, and the second clip-catching portion (434) and the second clip home (428) form mutual engagement in the horizontal direction.

Therefore, when the clip (430) is assembled to the first holder (410) and the second holder (420), the first holder (410) and the second holder (420) can maintain a strong mutual bonding force with the computer bolt (120), and can prevent the clip (430) from being separated from the computer bolt (120).

By fixing the cable (50) by inserting it into the first cable holder (401) and the second cable holder (402) while the above cable holder (400) is assembled to the computer bolt (120), the cable can be easily installed and the sagging of the cable (50) can be prevented.

The electrical work method of a rail structure using a computer bolt according to the present embodiment comprises: a step (S10) of installing an anchor bolt (110) on a ceiling; a step (S20) of assembling a computer bolt (120) to the anchor bolt (110) after step S10; a step (S30) of assembling a rail assembly (200) to a hanging bracket (130) arranged at the bottom of the computer bolt (120) after step S20; a step (S40) of assembling an electrical product to the rail assembly (200) after step S30; a step (S50) of temporarily fixing a cable holder (400) to the outer surface of the computer bolt (120); a step (S50) of installing a cable (50) to the cable holder (400) after step S50; and a step (S60) of fixing the cable holder (400) with a clip (430) after step S60. Includes step (S70).

The electrical work method of a rail structure using a computer bolt according to this embodiment has the feature of being able to easily adjust interference with the electrical product because a cable holder (400) can be temporarily installed on the upper side of the electrical product after the electrical product is installed, and then the cable (50) can be placed.

In addition, since the length and height of the cable can be easily adjusted through the cable holder (400), it is possible to easily respond to the on-site environment and has the feature of easily avoiding interference with fire extinguishing equipment such as sprinklers placed on the ceiling and structures such as air ducts.

Although the detailed description of the present invention has described specific embodiments, it is obvious that various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the claims described below, but also by equivalents of the scope of the claims.
