Structures for fixation prevention nets of falling rocks

The present invention relates to a rockfall prevention network fixing structure, and in particular, to a rockfall preventing network fixing structure, in which a wire rope provided on a surface of a rockfall prevention network acts organically to firmly support a slope, To a rockfall prevention network fixing structure.

In general, in the area where rockfall is likely to occur, a large number of wire ropes are installed on the top surface of the rockfall preventing net to secure the crossing portion of the wire rope to secure the rockfall preventing network. To prevent accidents.

However, this conventional technique has not been able to more effectively fix the wire rope provided on the surface of the fall-preventing network, thereby deteriorating the anti-rocking effect.

Accordingly, the conventional technology includes Patent Registration No. 10-0642141 and Patent Registration No. 10-0651655 filed by the present applicant.

Therefore, the main object of the present invention is to provide a rockfall prevention network fixing structure which is provided with a rockfall prevention network and is installed organically and firmly so that the rockfall can be generated and the supporting force can be efficiently exerted in the ground motion to support and stabilize the slope have.

In order to achieve the above object, according to the present invention, there is provided a rockfall prevention network fixing structure, comprising: a wire rope fastener having a guide groove for guiding a wire rope on each of the facing surfaces of the upper and lower plates, A connecting chain having an impact absorbing tube for connecting one end to the fixing member and absorbing impact energy; a strut supporting the fixing member by connecting the other end of the connecting chain; A rotation guide hole for adjusting the supporting force, and an escape preventing member for guiding the connecting chain by being coupled to the rotation guide hole.

Therefore, when the impact energy is transmitted to the rockfall preventing network and the wire rope, the supporting structure of the rockfall preventing network fixing structure of the present invention doubles the supporting force by the connecting chain connecting the fixing member and the support, Absorbing energy is absorbed by a plurality of shock absorbing tubes so that the shock absorbing tube absorbs the impact energy due to the pressure generated in the slope, So that it is possible to efficiently protect the slope and also to prevent a large accident by suppressing the intrusion of the rockfall or the slope caused by the collapse on the slope.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 7, the rockfall prevention network fixing structure includes guide grooves 112 for guiding the wire rope 10 on the respective facing surfaces between the upper and lower plates 111, and upper and lower plates 111 And a shock absorbing tube 121 connecting one end of the wire rope 10 to the fixture 110 and absorbing impact energy, and a connecting chain 120 A strut 130 for supporting the fixture 110 by connecting the other end of the connecting chain 120 and a connecting chain 120 connected to the upper portion of the strut 130, A rotation guide hole 140 for guiding the connection chain 120 to the rotation guide hole 140,

The fastener 110 is formed of upper and lower plates 111 and guide grooves 112 intersecting each of the facing surfaces of the upper and lower plates 111 to facilitate the crossing of the wire rope 10 .

Since the fastening bolt 114 for fastening the wire rope 10 in the state where the wire rope 10 is inserted into the guide groove 112 for coupling the upper and lower plates 111 is provided, the fastening bolt 114 is fastened to the upper and lower plates 111 The upper and lower plates 111 can press the wire rope 10 up and down to firmly fix the wire rope 10.

Further, it is preferable that the press bolt 113 is coupled to the upper center of the upper and lower plates 111 so that the lower end of the press bolt 113 can press the intersection of the wire rope 10 more firmly.

The connecting chain 120 includes a shock absorbing tube 121 forming a receiving space to penetrate the connecting chain 120. The connecting chain 120 punctures the supporting holes 123 in the left and right sides of the impact absorbing tube 121, 123 of the connecting chain 120 and one or more rings 120a of the connecting chain 120 are stacked in the inside of the shock absorbing tube 121 so that the space 120b of the ring 120a It is preferable that the hook 120a of the connecting chain 120 is assembled so as to maintain the overlapping state due to the fastening member 124. As a result,

Therefore, when the impact energy is applied to the connecting chain 120, the impact energy is absorbed while the shock absorbing tube 121 is broken, and at the same time, the rings 120a of the connecting chain 120 are overlapped by the fracture of the impact absorbing tube 121 It is preferable to expand the length of the connection chain 120 while absorbing the impact energy along the stones while expanding the surface area so as to effectively block the falling stone.

The support 130 is embedded in a slope and is formed with a fastening hole 131 at an upper portion thereof and an annular step 132 is formed at an outer periphery of the support 130. The fastener 110 and the support 130 are connected to each other by a connecting chain 120, It is preferable to connect them to each other so as to operate mutually.

The rotation guide hole 140 is formed with a through hole 142 formed at the center thereof so as to be rotatable by being inserted into the upper portion of the support column 130. The flange 141 is formed outwardly and downwardly, So that the connecting chain 120 is smoothly guided.

When the through hole 142 of the rotation guide hole 140 is coupled to the support 130, the through hole 142 is engaged with the annular protrusion 132 of the support 130, So that it can be assembled.

A through hole 152 is formed at the center of the releasing prevention part 150 and a fastening screw 153 is formed to vertically insert the through hole 142 of the through hole 152 and the rotation guide hole 140 A plurality of blocking pieces 151 are formed downward at the edge of the detachment support 150 so that the upper and lower ends of the rotation guide 140 It is preferable that the flange 141 is partly cut off so that the connecting chain 130 in the wound state can be prevented from being detached and the directionality can be maintained.

Here, it is preferable that the releasing end stop 150 and the rotation guide opening 140 are smoothly rotated so as to form a clearance with the upper surface of the engaging and releasing end 150 of the fastening screw 153.

The operation of the present invention will be described as follows.

First, a rockfall prevention net 1 is installed on a slope, a wire rope 10 is installed on the upper surface of a fall-prevention network 1, and then a fixing hole 110 is fastened and fixed to a crossing portion of the wire rope 10, The support 130 is embedded between the fixture 110 and the fixture 110 and the fixture 110 is connected to the fixture 110 by the connection chain 120 and fixed.

Therefore, when the ground motion of the slope or the falling rock caused by the slope occurs, the pressure is transmitted to the fall-prevention network 1 and the wire rope 10 and also to the connection chain 120 connecting the fixture 110 and the strut 130 So that the slope can be firmly supported by dispersing the pressure efficiently.

When the pressure is transmitted from the fixing member 110 to the connecting chain 120 at the position of the pressure generation position, the winding chain 120 of the rotation guide member 140 is pulled. At this time, the rotation guide member 140 rotates smoothly And the support 130 supports the support so that the slope can be stably supported by restraining the intrusion of the road.

Particularly, when an abnormal pressure is generated due to the ground motion of the slope or the rockfall, the slope is effectively supported and stabilized by the rockfall preventing net 1, the wire rope 10, the connecting chain 120 and the strut 130, So that the impact energy can be smoothly transmitted to the strut 130 and the fixing member 110 through the shock absorbing tube (not shown) 121), so that the impact energy due to the pressure can be efficiently absorbed and supported to protect the slope as well as to prevent large-scale accident by suppressing the intrusion of the rockfall or the slope caused by collapse on the slope .
