Description

Reinforcement structure of rockfall prevention measures {REINFORCED STRUCTURE OF FENCE FOR PROTECTING ROOF FALL}

The present invention relates to a reinforcing structure of a rockfall prevention measure, and in particular, by introducing a reinforcement structure of a rockfall prevention measure to prevent lost rockfall from being lost on the road, but in the event of a damage, the structural reinforcement of a rockfall prevention measure can be easily repaired. It is about.

Rockfall on roads may occur when cutting facilities such as mountains or hills to construct facilities or roads, and in reality, roads that penetrate mountains are dredged especially due to the geographic characteristics of Korea, where 70% of the country is mountainous. These places are always inherent in risks such as falling rocks or landslides due to damage to the inclined incision surface (rainfall or inadequate safety measures on the incision surface), which can directly affect not only road damage but also driving vehicles. It is often followed.

In order to prevent the above problems, the stabilization work of the incision surface is made first, and the rockfall prevention measures are installed on the edge of the road. Conventional general precautions are to install concrete in a certain distance from the ground, install an I beam, and form two coupling holes in the support to be spaced apart by a certain length, and then place a wire between the coupling holes and ridge on it. Most of them are fixed and installed. Such a structure is not only limited to a specific part of the occurrence of damage caused by the load is concentrated to the lower part of the preventive measure, in particular, the lower part of the preventive measures, but the reinforcement is made of wire, but the reinforcing force is less than the falling force of the falling rock In many cases, the falling rocks are lost on the road, and the repair cost is excessively generated by removing all the wires, meshes, and beams formed by a plurality of beams during repair. Therefore, in the conventional preventive structure, falling rocks are often left with damaged beams, cut wires, broken wires and bolt fasteners, or broken ridge bottoms.

In order to improve the above problems, the present inventors in the Republic of Korea Utility Model No. 256137 in the rock fall prevention plate is installed detachably, attached to the lower part of the frame, the front of the frame bottom of the rock fall prevention pack on both sides of the blocking plate Brackets are attached to the upper and lower corners by welding, and four corners of both sides of the blocking plate are rotatably installed, and the brackets attached to the frame are formed in front of the brackets. , The rear part proposed a rockfall prevention measures characterized in that the support portion for supporting the back of the blocking plate is formed. The above devises can reliably secure the structural strength of the rockfall prevention measures by deviating the method of weakening the structural strength of the prevention measures by drilling the fastening holes in the conventional frame, and the strength of the frame by the bracket attached to the frame to some extent. There was an advantage in that the separation and recombination of the components could be done quickly and easily. However, in the use of the barrier plate, the fall prevention measures that are already in use have been exposed to the problem that the renovation method is not a complementary concept and is expensive. The present inventors will develop a reinforcing structure applicable to the pre-installed prevention measures while maintaining the advantages of the conventional design.

In order to solve the above problems, an object of the present invention is to provide a reinforcement structure of a safe fall prevention measure by installing a foundation bolt as a support between each beam as a reinforcing means of a fall prevention measure.

Another object of the present invention is to provide a reinforcing structure that can repair only the damaged part when the preventive measure is damaged by the rockfall, thereby reducing the repair time and cost.

Another object of the present invention is to provide a reinforcing structure of the rockfall prevention measures that can be installed in parallel with the conventional rockfall prevention measures.

In order to achieve the above object, the present invention is designed to prevent rockfall, and a bracket having a shape of a 'U' shape is fixed to the beam, and the L type foundation bolt is inserted into the bracket of one beam and the bracket of the next beam, and of the foundation bolt. The L-shaped bent portion is fastened to the outer circumferential surface of the bracket, and the threaded threaded portion provides a reinforcement structure of a rockfall prevention measure that is fastened to the adjacent bracket by a nut.

In addition, the present invention provides a reinforcement structure of the rock fall prevention mechanism wherein the bent portion is located at the beam side of the bracket and the screw portion is located at the 'U' curved point of the adjacent bracket.

In addition, the present invention provides a reinforcement structure of the rockfall prevention barrier is installed in the lower portion of the beam reinforcement structure including the bracket and the foundation bolt.

In addition, the present invention provides a reinforcing structure of the rockfall prevention measures that are inserted staggered in the foundation bolts to strengthen the support capacity of the ridge net against rockfall.
