Description

[Detailed Description of the Invention] The present invention is designed to prevent the opening of the incision in order to prevent the branch line attached to the protective guard that covers the branch line stretched to keep the utility pole in a vertically erected state from being pulled out. It concerns fasteners.

Conventionally, as a means of preventing the opening of the cutout of this type of branch line protection guard, a protruding piece for attaching a fastener is provided on the outside of the cutout provided in the longitudinal direction of the long cylindrical tube, and The incision was closed by tightening it using fasteners such as bolts and nuts. In this case, not only does it take time to tighten the bolts and nuts, but the protruding pieces used to tighten the fasteners may cause an imbalance in the weight of the long cylindrical pipe, and the protruding pieces may not function as wind plates. There were drawbacks such as the cables rotating and becoming unstable, and the branch line protection guard being damaged. Therefore, in order to solve this problem, we removed the protruding piece and applied a band, etc., to the incision of a long cylindrical tube at right angles to the incision so as to straddle the incision, and screwed screws, etc. to both ends of this band. There is also a band that is tightened to a long cylindrical pipe to prevent the incision from widening, but with such a band, the band is fixed with screws etc. at the construction site, making it difficult to install. There was an inconvenience that it took a long time.

In view of this situation, the present invention has been devised to provide a fastener that prevents the opening of the incision of the branch line protection guard, which eliminates the conventional drawbacks. A round hole is formed at the other end of the band piece, and the rivet-like body has a large diameter portion at the tip, and is further divided by cutting in the axial direction so that the diameter can be contracted and restored. and a mooring member to be fitted into the other locking hole of the guard body is loosely fitted into the circular hole, and a cutout provided in the longitudinal direction of the guard body made of a long cylindrical tube is inserted into the circular hole. Attach the fastener to the guard body by pushing a stud-like object into one of the opposing locking holes in advance, and push the mooring member into the other locking hole while it is attached to the branch line at the construction site. This makes it possible to prevent the opening of the cutout portion of the guard body with good work efficiency.

Embodiments of the present invention will be described below with reference to the drawings.
In the figure, 1 is a guard body made of a long synthetic resin tube with a cylindrical inner diameter that can accommodate a connecting fitting connecting an anchor bolt B and a branch line C. It is formed so that it can be opened. The guard body 1 is provided with locking holes 3, 3' at appropriate intervals across the cutout 2, and a cap 4 is fitted to the end.

Reference numeral 5 denotes a flexible band piece having a substantially rectangular shape, and integrally provided with a stud-like body 6 protruding from one end thereof to be fitted into a locking hole 3 formed by sandwiching an incision 2 in the guard body 1. A circular hole 7 is opened at the other end of the band piece 5. The rivet-like body 6 is provided with a large diameter portion 8 at its tip, and further provided with a notch 9 in the axial direction so as to be divided so that its diameter can be contracted and restored. Reference numeral 10 designates a mooring member that loosely fits into the circular hole 7 and is moored to the locking hole 3' opposite to the locking hole 3, and has a cylindrical body 12 with a flange 11 at one end and a diameter gradually increasing toward the other end. Cuts 13, 13 are provided crosswise in the axial direction of the cylindrical body 12, and the pin 14 is loosely inserted into the cylindrical body 12 so as to be vertically movable.
The diameter of the cylindrical body 12 can be contracted when the pin is pulled up, and when the pin 14 is pushed in as shown by the chain line in Figure 5, the diameter of the cylindrical body 12 is kept uncontractable, similar to the drive unit. .

The thus formed fastener A is attached in advance by fitting the stud-like body 6 into one of the locking holes 3 of the guard body. At this time, the mooring member 10 is loosely fitted to the band piece 5 and is left free from the guard body 1.

Figure 6 shows the state of use, and shows the utility pole D.
If the incision 2 is expanded for the branch line C which is stretched in an inclined manner between the anchor bolt B and the anchor bolt B whose one end is buried in the ground, and the guard body 1 is passed through, it will enter the gap 4' of the cap 4. It enters the center of the cap 4, fits into the branch line insertion hole, and is held.

Then, the expansion of the cutout 2 of the guard body 1 is stopped, and the mooring member 10 is loosely fitted into the circular hole 7 of the band piece 5.
is fitted into the other locking hole 3' of the guard body 1 with the pin 14 pulled up, and then the pin 14 is pushed into the cylindrical body 12 to exert a drive-like action and lock the fastener A. It can be securely anchored to the guard main body 1 and reliably prevent the incision 2 from opening.

As described above, the fastener of the branch line protection guard of the present invention has a stud-like body integrally protruding from one end of the band piece, and a mooring member loosely fitted into the circular hole provided at the other end of the band piece. Since it is a pre-formed structure, a rivet-like body is fitted in advance into one of the locking holes that are placed opposite to each other by sandwiching the incision in the guard body, and the guard body is attached to the branch line at the construction site. In this state, by inserting the anchoring member into the other locking hole and pushing in the pin, the band piece can be easily attached to the cutout of the guard body with a single touch operation, and the cutout can be prevented from opening. Therefore, the band piece is carried to the construction site together with the guard body, and the mooring member is loosely fitted to the band piece, so it does not get lost, and there is no hassle of attaching it on site, improving efficiency. You can reach your goals well.
