The present invention relates to a rockfall prevention facility (fallfall prevention network, fallfall prevention measures), and more particularly, wire ropes can be installed in a cross shape and a rhombus shape according to the conditions of the construction site, and also for a fallfall prevention facility that can be used in parallel with a cross shape and a diamond shape It relates to a wire rope cross-shaped and rhombic installation combined binding device and a method of constructing a fall prevention facility using the same.

This section provides background information related to the subject matter of this application and is not necessarily prior art.

In general, rockfall prevention facilities are installed in areas where there is a risk of falling rocks due to the formation of bedrock on the slope of the incision to prevent industrial accidents and traffic accidents.

Fall prevention facilities include, for example, a fall prevention net that prevents falling rocks by attaching a net to the wall of a bedrock and installing a number of wire ropes in various directions to adhere the net to the slope, and a rock falling from the slope installed on the roadside below the slope. There are measures to prevent falling rocks from encroaching on the roadside.

The fall prevention network connects a net (for example, a PVC coated net) covered on a slope or a rock wall, a wire rope that allows the net to be in close contact with the slope, and an intersection of the wire rope and an end of the wire rope. It is configured to include a fixture for fixing. That is, in a state in which the net is covered on the slope, the wire rope is disposed in the longitudinal and transverse directions, and the intersection portion of the wire rope and the end of the wire rope are fixed with a fixture.

The wire ropes of conventional rockfall prevention facilities (rockfall prevention net, fall prevention measures) are installed in a cross shape (cross type) or diamond shape (zigzag shape), and due to the difference in these wiring directions, a dedicated binding tool suitable for each wire is used and Therefore, when the wiring direction is changed at the construction site, time is wasted because the binding tools must be prepared again, and if all exclusive binding tools are prepared, unnecessary costs are wasted. cannot be prepared, and it is difficult to freely change the wiring at the construction site.

The binding body 10 is a plate material of a size capable of accommodating wire ropes in both a cross shape and a diamond shape, and fixing holes 11, 12, 13, and 14 for cross wiring are formed on the top, bottom, left and right sides, respectively, and also fixing them At least one pair of fixing holes 15 and 16 for diamond wiring are formed along an oblique direction at a position that does not overlap with the ball.

The fixing holes 11, 12, 13, and 14 for cross wiring vary according to the shape of the fixing tool 20 for cross wiring, and each two holes are shown as an example.

The fixing holes 15 and 16 for the diamond wiring are formed as a pair in accordance with the fact that the fixing tool 30 for the diamond wiring is a U-bolt.

In particular, the fixing holes 15 and 16 for the diamond wiring are formed in an arc shape (curved shape) so that the position of the fixture 30 for the diamond wiring can be adjusted, and the wire rope 1 in the longitudinal direction and the wire rope 2 in the transverse direction It is formed in a length that occupies one or more of the wiring paths, and through this structure, the rhombic wiring fixture 30 presses the wire rope in the longitudinal/transverse direction, thereby pressing the wire rope in the longitudinal/transverse direction due to rockfall (1, 2). ) can reduce movement.

Binding body 10 may include a semicircular bending portion to cover a portion (eg, half) of the wire rope.

In addition, an anchor hole 17 for fixing the binder body 10 to the slope may be included, and the anchor 18 is fastened to the anchor hole 17 and the anchor 18 is inserted into the slope to fix the binder body. (10) is fixed to the slope.

The fixture 20 for cross wiring fixes the wire ropes 1 and 2 in the longitudinal/transverse direction without leaving the binder body 10, and as shown in the drawing, the wire rope 1 in the longitudinal/transverse direction U-bolt 21, which is fixed by tightening the nut 22 after the bolts on both sides pass through the fixing holes 11, 12, 13, 14 for cross wiring of the binding body 10 while surrounding the circumference of , 2) am.

At this time, it is possible to use U-bolts 21 on both the upper, lower and left sides, but it is not limited thereto, and any one of the upper and lower sides and the left and right sides is a U-bolt, and a combination type consisting of two straight bolts is also possible.

The fixture 20 for cross wiring is not used for diamond wiring.

The rhombic wiring fixture 30 can have any shape in which the rhombic wire ropes 3 and 4 are caught on both sides and the direction can be changed, and is preferably a U-bolt 31 and a nut 32.

In the U-bolt 31 of the rhombic wiring fixture 30, the diamond-shaped wire ropes 3 and 4 are hooked on both bolt parts 33 and 34, respectively, to induce the direction change of these wire ropes 3 and 4. can

The U-bolt 31 may be replaced with two straight bolts capable of inducing and supporting the direction change of the wire ropes 3 and 4, respectively.

The U-bolt 31 is fixed to the binding body 10 by fastening the nut 32 after the bolt parts 33 and 34 pass through the fixing holes 15 and 16 for the rhombic wiring from the bottom to the top, respectively.

In addition, as described above, the U-bolt 31 generates a braking force by pressing the wire ropes 1 and 2 in the longitudinal/transverse directions through the fixing holes 15 and 16 for the lozenge wiring.

In the U-bolt 31, the bolt parts 33 and 34 on both sides can press and support both sides of the longitudinal wire rope 3 or the transverse wire rope 4, respectively, or the longitudinal wire rope 3 ) and one side of the wire rope 4 in the transverse direction may be pressed and supported.

The U-bolt diamond wiring fixture 30 may not be used for cross-shaped wiring, but as described above, it may be used for braking of the wire ropes 1 and 2 in the longitudinal/transverse directions.

The fixture 30 for diamond wiring of U-bolt may require a gap between the binding body 10 to change the direction of the wire ropes 3 and 4, and for this purpose, the bolt parts 33 and 34 are fixed, respectively. Lengths of pipe can be combined.

9 and 10 show an example in which the pressure bolt 35 is added to the diamond wiring fixture 30, and the binding hole 15 and 16 for the diamond wiring and a certain interval (of the wire rope) Arc-shaped (curved) bolt long holes 19 are formed at intervals smaller than the thickness), and after the pressing bolts 35 pass through the bolt long holes 19, they are fixed by fastening nuts.

In this case, the U-bolt 31 and the pressure bolt 35 can press and support the wire ropes 3 and 4 from both sides with the wire ropes 3 and 4 interposed therebetween, so that the braking force of the wire ropes 3 and 4 can be made larger.

The bolt long hole 19 is to be used for wire ropes 3 and 4 of various thicknesses by changing the position of the pressure bolt 35.

A fastener 40 may be further installed in the binder body 10 .

The fastener 40 is screwed into the female screw portion formed in the binding body 10, and its position is the intersection of the wire rope 1 in the longitudinal direction and the wire rope 2 in the transverse direction. When the directional/lateral wire ropes 1 and 2 are pressurized and installed as a fall prevention net, the slope can be stably protected through the wire ropes 1 and 2 by pressing them toward the slope side.

According to this configuration, it is characterized in that it can be used even in the field where cross-shaped wiring and rhombic wiring are used in parallel.
