Description

[Detailed Description of the Invention] The present invention relates to a rope support pile for tying and supporting a rope to which a wire mesh is attached when a rock fall protection net is stretched on an inclined wall.

Generally, when using this type of rope support pile to install a rockfall protection net, it is connected to the top of a restraining lobe support shaft attached to the upper anchor, and the rope support pile is reinforced by this restraining rope. Since most of the downward load will be applied to the upper anchor, the anchor must also have a corresponding strength.

However, the terrain where rockfall protection nets are usually installed is topographically rugged, and it is extremely difficult to install anchors that can withstand excessive force in such places. It is often difficult to maintain sufficient strength in support piles.

In view of the above, the present invention aims to reduce the force applied to the upper anchor by increasing the erection strength of the rope support pile, and at the same time, to enable the inclination angle of the rope support pile to be easily and arbitrarily set. The lower end of the column for tying and supporting the rope is rotatably connected to a rectangular cylindrical holder fixed on an inclined wall, and multiple locking devices are attached to the opposing side walls of the holder. The present invention is characterized in that the port is screwed in such a way that it can move forward and backward, and the tip of each port is brought into contact with the side surface of the support column, so that the support support is held at a constant angle of inclination by the port.

Hereinafter, embodiments of the present invention will be explained in detail based on the drawings. In FIG.
A large number of rope support stakes 1 are erected on the left and right at appropriate intervals, and a wire mesh 3 and a vertical rope 4 to which the wire mesh 3 is attached are tied to the rope support stakes 1, and the rope support stakes 1 are pulled from above. The other end of the retaining rope 5 is tied to an anchor port 6 fixed to the slope 2.

Yes, the vertical rope 4 and the restraining rope 5 may be a series.

As shown in FIGS. 2 to 4, the rope support pile 1 is
A strut 7 with an H-shaped cross section for binding and supporting the ropes 4 and 5, and an L-shaped fixing plate 9 for fixing on the slope 2 are attached to the left and right side walls 8a, 8a. The left and right side walls 8a of the holder 8 are made of a rectangular cylindrical holder 8.

8a has a connecting groove 10.10 extending downward from its upper end.
On the other hand, the front and rear side walls 8b, 8b are provided with a plurality of engagements at the upper and lower positions thereof that hold the support 7 at a constant inclination angle by being in equal contact with the side pieces 7a*7a of the support 7. The locking bolts 11, 11, . . . are respectively screwed so that they can move forward and backward.

When erecting the rope support pile 1, first, the fixing plates 9, 9 of the holder 8 are tightened to the anchor bolts 12 buried on the slope 2 through the nuts 13. The lower end of the column 7 is inserted into the inside of the holder 8, and the connecting bolt 14 inserted through the lower end of the column 7 is fitted into the connecting groove 10. By loosely screwing the support column 7 to the holder 8, the support column 7 is temporarily connected to the holder 8 so as to be freely rotatable.

Next, with the support 7 tilted and its angle set, the locking holts 11, 1 are screwed onto the side walls 8b, 8b of the holter 8.
1. The tips of these locking bolts are brought into contact with the side pieces 7a, 7a of the column to hold the column 7 at that inclination angle, and then the above-mentioned connection is made. Tighten the nuts 15 and 15 of the bolt 14 firmly, and
to be fixed.

The holder 8 is provided with a bolt that closes the upper part of the connecting groove 10 in order to prevent the connecting bolt 14 from coming out of the connecting groove 10 when working with the column 7 temporarily connected.
It is necessary to install the bolt 16.

Furthermore, as shown in FIG.
The slope 2 can also be tilted in the left and right directions, in which case the nuts 15, 15 and the side walls 8a, 8 of the holder 8
If a wedge-shaped spacer 17.17 is interposed between them, the nut 15.15 can be tightened easily and the tightening strength can be increased.

According to the rope support pile of the present invention having the above configuration, a plurality of locking bolts threaded onto the side wall of the holder are brought into contact with the side surface of the support column, and the support column is held at a constant inclination angle by these bolts. As a result, the load acting on the column can be supported by these tilting bolts, which can significantly reduce the force applied to the upper anchor through the restraining rope. The angle can be easily set to suit the slope by adjusting each locking bolt, which allows the rope to be hung in a straight line.
