Abstract

The present invention relates to a wire-fixing and safety-alarming device for a falling-stone prevention barrier. The wire-fixing and safety-alarming device minimizes damage to a structure thereof by partially absorbing excessive impact applied to a wire which is provided on a falling-stone prevention barrier or a guard rail along the side of a road when both ends of the wire are fixed to a support pole and allows a restoration work to be simply and quickly performed. The wire-fixing and safety-alarming device for a falling-stone prevention barrier comprises a socket which binds the end of the wire; a support rod of a splicer, which has the socket on one end and spiral parts at regular intervals formed thereon; a through hole which is formed on a support pole on the edge of the falling-stone prevention barrier and has the spiral parts passing through the through hole to apply proper tension to the wire; a compression spring which is inserted into the spiral parts protruding toward the outside of the support pole while the proper tension is applied to the wire; and a stopper and an elastic member which are inserted into the rear end of the spiral parts. The fixing and safety-alarming device is capable of removing a small amount of falling stones in advance, since a compression spring is compressed and comes in close contact with a limit switch to turn on a warning light which emits a signal to a management office when the wire is extended by a falling stone. The wire-fixing and safety-alarming device absorbs the impact of a large amount of falling stones as a break nut is secondarily broken to cushion the impact of the falling stones and spread the weight of the falling stones in order to protect the support pole and having a limit nut which finally stops the expansion of the wire, thereby minimizing damage to the falling-stone prevention barrier and cars, and loss of lives.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wire-

More particularly, the present invention relates to a wire fixing and safety alarm device for preventing a rockfall, and more particularly, it relates to a wire fixing and safety alarm device for preventing the falling of a road, And more particularly, to a wire fixing and safety alarm device for a rockfall prevention device that can minimize the damage of the vehicle and minimize the damage of the vehicle.

Generally, when a road is constructed on a mountainous terrain, a rockfall prevention device is installed on a site where a loss of rockfall or soil is predicted, and a guard rail (including a frame type guardrail) is provided on a roadway such as an automobile road or an obstacle road. To ensure safety.

The above-mentioned anti-rocking measures or the installation of the guard rails are specified in relevant laws and regulations in order to maintain the safety of the road. In order to provide a strong tension over a long distance, Wire is installed.

As described above, in the conventional rockfall prevention measure, when a large amount of rockfall and sand is suddenly hit against the wire mesh 13 and a force greater than the initial tension given to the wire 02 supporting the wire mesh is applied, There has been a problem that an impact is applied to the nut which is the weakest part of each part of the splicer 05, and the part is broken.

Also, the partial breakage phenomenon of the springs (05) for fixing the wire leads to the loss of tension of the wire, and the force corresponding to the collapsed soil or rockfall is lost so that the wire mesh (13) is broken or the support column And a collapse accident occurred.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the conventional rockfall preventive measures, and its object is to partially absorb the impact when an impact is applied to a wire installed to support a load of a rock or a rockfall, The present invention provides a wire fixing and safety alarm device for preventing a large number of falling rocks by an alarm device in the case of falling rocks.

In order to solve such a problem, the present invention is characterized in that a spiral portion is formed at a predetermined distance in a support rod of a sprue having a socket at one end thereof for binding ends of a wire, and the spiral portion of the support rod is inserted into a through hole The compression spring is inserted into the spiral portion protruding outwardly of the support column and the stopper and the elastic member are inserted into the rear end of the spiral spring, , The warning light is turned on and the signal is transmitted to the station so that a small amount of rockfall can be removed in advance as a safety device by rockfall.

In addition, a large number of rocks are secondarily damaged by breakage of the fracture nut, and the support pillars are protected by dispersing the weight. Finally, the tension of the wire is stopped by the limit nut, .

As described above, the wire fixing and safety alarm device for anti-rockfall measures of the present invention detects a small amount of rockfall by the compression spring that fixes the end portion of the wire to the support column when an impact exceeding the tension given to the wire is applied, In the case of a large number of rockfall, the impact load is relieved primarily by the compression spring and the elastic member. In addition, a large number of rockfall secondaryly breaks the fracture nut located at the rear of the elastic member, And the tension of the wire is finally stopped by the limit nut, so that there is an effect that breakage of the anti-rocking measure, damage of the vehicle and damage of the person can be minimized.
