The present invention is to prevent rock collapse to fix the wire rope installed in the cross-outside of the rock fall prevention net in order to fix and detain the rock fall prevention net (core blanket) installed on the surface of the incision site generated when the road and tunnel construction A wire rope fixture.

In more detail, the wire rope battery strip is formed in the shape of a cup having an open top, a wide top, and a narrow bottom, and the wire rope is pulled in and loaded into the top of the wire rope loaded into the battery strip. The present invention provides a wire rope fastener for preventing rock collapse by providing a wire rope presser and fastening the wire rope battery strip and the wire rope presser with a conventional lock bolt and a nut embedded in the ground.

In order to prevent the surface of the incision site, rock wall, and rock, which are generated during the construction of roads and tunnels, from collapse by impact, wind and gravity, the surface is covered with a rockfall protection net (core blanket), and a rockfall prevention net ( On the upper side of the core blanket) is installed to keep the wire ropes at equal intervals and install the fixtures at the intersections of the wires to fix the rockfall prevention net (core blanket) with the wire rope.

Conventional apparatuses installed for the above purposes include domestic utility model registration No. 255620, utility model registration No. 287784, utility model registration No. 313319, patent registration No. 261973, patent registration No. 415170, patent registration No. 464593. And the like are known.

Korean Utility Model Registration No. 255620 and Utility Model Registration No. 287784 and Patent Registration No. 415170 fasteners (falling-proof wire rope fixtures) form a guide groove in a straight or cross shape inside the fixture, and the fixture Opposite at the intersection, the opposing fixture is to be mounted (bound) by bolts / nuts.

However, this is just to bind (weave) only the wire rope because the pair of fasteners are mounted at the intersection of the wire rope, and the wire rope and the rockfall prevention net (core blanket) are ground because only the wire rope is bound. There is a problem that cannot be fixed on the ground, and the wire rope and rockfall protection net (core blanket) cannot be fixed on the ground, so that the surface, rock walls, and rocks are not collapsed by impact, wind and gravity. Efficiency) is inferior.

Registered Utility Model No. 313319, "Wire pressure plate of rockfall prevention metal net", fastens a pillar to be buried underground in the center of the pressure plate, inserts a pair of bolt holes in the corner of the pressure plate, and inserts the U bolt from the bottom. It is fixed by the nut of, but the opposite U bolt is to be fitted by inserting the crossing wire rope.

However, in order to fix the wire ropes to be installed crosswise, wire ropes should be fitted to the U bolts (inside), and each U bolts should be mounted (fixed) at the corners of the acupressure plate, thus requiring a lot of work time. There is a problem of falling, and because it is intended to simply put the struts fastened to the pressure plate in the ground, there is a problem that the struts embedded in the ground can be easily separated by shock and vibration, so that the wire ropes cannot be firmly fixed.

Registered Patent No. 447793 "Rockbolt interlocking reinforcement device for preventing rock collapse" is formed on the upper surface of the lower support where the lock bolt is fixed (installed) on the center line to form four anti-jaw in a square shape to hang the wire rope to cross In the upper side of the lower supporter, the upper supporter is inserted into the lock bolt, and the locking jaws are inserted into each of the four gripping holes drilled in the upper supporter, respectively. By screwing together, the wire rope is held by the upper and lower supports.

However, this is merely to support the wire rope which hangs on the lower jaw of the lower support by the opposing surface of the upper support and the lower support, so that the wire rope and the rockfall prevention net (core blanket) cannot be firmly fixed to the ground. There is a problem, and the wire rope and the rockfall protection net (core blanket) cannot be fixed to the ground, as well as merely supporting the wire rope, so that the wire rope cannot be installed with tension and thus the rockfall protection net ( Core Blanket) can not be detained reliably, and the surface, rock walls, and rocks cannot be prevented from collapsing due to impact, wind and gravity, that is, there is a problem that the collapse prevention function (efficiency) falls.

In addition, Patent No. 415170, "rock bolt connection device for preventing rock collapse," fills the mortar by inserting the rock bolt into the underground hole drilled in the ground layer of the slope, and the hole is drilled in the center of the support plate in the rock bolt exposed to the upper side of the surface Insert and combine the wire fixture in the state of crossing the wire rope on the basis of the lock bolt exposed to the upper side of the support plate, inserting the cross wire rope into the fixing groove formed to cross the side of the wire fixture, The conventional nut is screwed and fixed to the distal end of the lock bolt protruding upward from the center of the wire fixing tool.

However, this also merely supports the wire rope stretched by the support plate and the wire fasteners, so that the wire rope cannot be installed with tension, and thus the rockfall prevention net (core blanket) cannot be detained steadily. And rock walls and rocks can not be prevented from collapsing by impact, wind and gravity action, that is, there is a problem that the fall prevention function (efficiency) is lowered.

The present invention is to provide a wire rope fixture for preventing rock collapse more improved to solve the above problems.

According to the present invention, the wire rope battery strip is formed in the shape of a cup having an open top and a wide top and a narrow bottom, and the wire rope is pulled in and loaded, and the wire rope is crimped on the upper side of the wire rope loaded into the battery strip. An object of the present invention is to provide a wire rope anchoring device for preventing rock collapse that is intended to fasten a wire rope battery strip and a wire rope crimping hole with a lock bolt and a nut embedded in the ground.

Another object of the present invention is to keep the wire rope in a tense state by introducing the wire rope detained by the wire rope battery strip and the wire rope crimping hole into the wire rope battery strip to strengthen the tensile force. In addition, it is possible to reliably detain the rockfall prevention net (core blanket) by the wire rope that is kept taut, and to prevent the surface, rock walls, and rocks from collapsing by impact, storm, and gravity. The present invention provides a wire rope fixing device for preventing rock collapse, which can improve the collapse prevention function (efficiency).

Still another object of the present invention is to form a loading groove on the inner surface of the wire rope battery strip to widen the contact area between the wire rope and the wire rope battery strip inserted into the wire rope battery strip to be loaded more securely. The present invention provides a wire rope fastener for preventing rock collapse.

Still another object of the present invention is to form a wire rope battery strip and a wire rope crimp in a cylindrical or polygonal (square and octagon) to be selectively installed according to the installation location and use, wire rope battery strip and wire The present invention provides a wire rope fastener for preventing rock collapse that can be easily manufactured and installed by simplifying the structure of a rope crimping tool.
