Falling Rock Preventing Fence With Fabrication Typewire Net

Abstract

A falling rock preventing fence assembled with a steel net is disclosed, in which a plurality of support members are provided in a pipe shape having a rectangular grooves in upper and lower longitudinal directions, with the support member being installed on the ground at regular intervals, and both ends of the steel net formed in a rectangular plate shape are inserted into the rectangular grooves of the neighboring support member and are fixed using a fixture such as a bolt, etc., and the upper and lower portions of the steel nets stacked in the upper and lower direction are connected with a connection member such as a bolt, etc., and the strength of the steel net is enhanced by the rectangular grooves longitudinally formed in the support member and the end of the steel net inserted in the rectangular groove.

1 . In a falling rock preventing fence which includes a plurality of support members  10  vertically installed on the ground at regular intervals, a plurality of wire ropes  20  which horizontally pass through the support members  10 , a plurality of wire rope fixtures  21  which are fixedly installed at the support members  10  provided at both ends for thereby fixing the both ends of the wire rope  20 , and a steel net  30  installed at a back surface of the support member, a falling rock preventing fence assembled with a steel net characterized in that the support member  10  is formed in such a manner that a rectangular groove  12  is formed over the entire length of the back surface of the body  11  formed in a pipe shape, and a rope through hole  15  passes through the outer surface of the body  11  and the lateral side of the both sides of the rectangular groove  12 ; the steel net  30  is formed in such a manner that a groove insertion portion  32  inserted into the rectangular groove  12  of the support member  10  is formed at both sides of the steel net body  31  formed in a rectangular plate shape so that it is inserted between the neighboring support members  10 , and an upper and lower connection portion  35  is formed at the upper and lower portions of the steel net body  31  for engaging the upper and lower portions of the steel net  30  stacked between the support members  10 ; and the wire rope  20  horizontally passes through the rope through hole  15  formed at the support member  10 ; and two groove insertion portions  32  installed near the lateral sides and meeting with each other are inserted into the rectangular groove  12  of the support member  10 , and a cover member  1  is installed at the rear side of two groove insertion portions  32  inserted together with the rectangular groove  12  for supporting the lateral ends of the steel net  30 , and the support member  10  and the steel net  30  are fixed using a fixing bolt  2  or a U bolt. 
   
   
       2 . The wall of  claim 1 , wherein said groove insertion portion  32  is bent at both sides of the rectangular frame  37  in which the steel net body  37  is fixed, and the cut portion  33  through which the wire rope  20  passes and the bolt insertion hole  34  through which the fixing bolt  2  passes are formed at the groove insertion portion  32 , and the upper and lower connection portion  35  is formed at the upper and lower ends of the rectangular frame  37  in which the horizontal steel plate is horizontally bent, and an engaging hole  36  is formed at the horizontal steel plate and is engaged using a screw or a rivet; and an angular pipe  3  is inserted between two groove insertion portions  32  inserted together with the rectangular groove  12 . 
   
   
       3 . The wall of  claim 1 , wherein said groove insertion portion  32  is bent at both sides of the rectangular frame  37  in which the steel net body  31  is fixed, and the bent width portion of the groove insertion portion  32  is bent in a channel shape as wide as the half of the width of the rectangular groove  12 , and a cut portion  33  is formed at the groove insertion portion  32  with the wire rope  20  passing through the cut portion  33 , and the upper and lower connection portion  35  is formed at the upper and lower ends of the rectangular frame  37  so that the horizontal steel plate is horizontally bent, and an engaging hole  36  is engaged at the horizontal steel plate using a screw or a rivet. 
   
   
       4 . The wall of  claim 1 , wherein said steel net body  31  is engaged in a rectangular net shape in which a plurality of vertical and horizontal wires  31   a  and  31   b  are engaged, and an upper and lower connection portion  35  is formed at the upper and lower ends of the vertical wire  31   a  in a right triangle shape, and the upper and lower connection portions  35  contacting with each other are engaged using a clip  38 , and the horizontal wire  31   b  is protruded from both ends of the steel net body  31 , and the groove insertion portion  32  is engaged at the protruded ends, and a cut portion  33  is formed at the groove insertion portion  32  with the wire rope  20  passing through the cut portion, and an angular pipe  3  is inserted between two groove insertion portions  32  inserted together with the rectangular groove  12 .
