The wire 180 is manufactured linearly using steel to secure a predetermined stiffness and tensile strength. However, since the wire 180 is elongated or contracted according to a temperature change, a sag prevention means that can prevent sagging due to a change in the length of the wire 180 is also provided. Prepared.

Specifically, referring to FIGS. 1 to 5, the wire-type safety fence of the present invention includes at least one of the filler 200, the handrail bar 100, the wire 180, and the deflection prevention means.

The ground 290 is made of concrete or stone is installed on the ground, and the filler 200 is firmly fixed to the base 290 and is erected perpendicularly to the ground to be a pillar of a safety fence. A base bracket 250 is provided to fix the filler 200 and the base 290.

The bottom surface of the base bracket 250 is fixed to the base 290, and protruding plates 252 and 254 of one phase are provided above the base bracket 250. The web 210 of the filler 200 is fitted into the empty space between the pair of protruding plates 252 and 254. When the protruding plates 252 and 254 and the web 210 are fastened, the protruding plate holes 256 provided in the protruding plates 252 and 254 and the protruding plate hole fastening portions 266 provided in the web 210 are coincident with the bolts or rivets. Penetrate the base bracket 250 and the filler 200 through.

The filler 200 may be made of various materials such as steel, aluminum alloy, synthetic resin, synthetic wood, FRP, and wood, and the cross section of the filler 200 has an 'H' shape. The filler 200 includes a web 210 provided at the center, a first flange 271 extending perpendicular to one side of the web 210, and a second flange 272 extending perpendicular to the other side of the web 210. ).

The first flange 271 and the second flange 272 may have different lengths, wherein a filler groove is an empty space formed by the first flange 271, the second flange 272, and the web 210. Reference numeral 235 is a cross-sectional shape having a quadrilateral shape. The empty space formed by the filler groove 235 is a space in which the deflection preventing means of the wire 180, the end bar 302, the stopper 183, and an intermediate portion of the wire 180 are accommodated.

The outer side of the first flange 271 and the second flange 272 is preferably provided with intermittent protrusions for the purpose of strength reinforcement or preventing the adhesion of contaminants. The first flange 271, the second flange 272, and the web 210 may be hollow, and at this time, material cost reduction and self weight reduction of the filler 200, as well as processing holes or grooves in the filler 200, may be performed. It is easy to do, and there is an advantage in that it is easy to assemble other parts such as the handrail bracket 400 to the filler 200. For example, a web groove 240 is formed at an upper side of the web 210, and the anchor plate 420 of the handrail bracket 400 is inserted into and fixed to the web groove 240.

The filler groove 235 may be exposed at the distal end of the safety fence, and the end bar 302 may be fitted to prevent the filler groove 235 from being exposed. The filler groove 235 may be provided with a first stopper 230 or a second stopper 232 to facilitate attachment or detachment of the end bar 302 with respect to the filler 200.

When the lengths of the first flange 271 and the second flange 272 are different, the cross section of the end bar 302 becomes trapezoidal, and the surface exposed to the outside becomes the inclined surface 303 of the end bar 302. One side and the other side of the end bar 302 are elastically supported by the first stopper 230 or the second stopper 232 and the first stopper 230 and the first stopper to prevent the end bar 302 from being separated. The direction in which the inclined gradients of the two stoppers 232 are formed may be opposite to each other. According to the illustrated example, the inclined gradient of the first stopper 230 faces the outside of the filler groove 235 and the inclined gradient of the second stopper 232 faces the inside of the filler groove 235. When the end bar 302 is inserted into the filler groove 235, the apex of the inclined gradient of the first stopper 230 resists the end bar 302 from being pushed out of the filler groove 235 and the second stopper 232. The apex of the inclined gradient of) resists the end bar 302 from being pushed into the filler groove 235.

Therefore, when the end bar 302 is first inserted into the portion of the second flange 272 having a relatively short length and the end bar 302 is inserted into the filler groove 235 while rotating the end bar 302 in the axial direction, the second stopper 232 ) Prevents the rotation of the end bar 302 in the reverse direction and the first stopper 230 has a sloped portion facing the side of the end bar 302 so that the end bar 302 has a small force on the filler groove 235. Make it slideable. When the length of the first flange 271 is relatively long, the number of the first stoppers 230 may be greater than that of the second stoppers 232, and the first flanges 271 may be larger than the second flanges 272. Since it has a small elasticity, the end bar 302 inserted into the filler groove 235 by the inclined gradient of the first stopper 230 may not be easily separated in the opposite direction.

The handrail bar 100 is a rod that connects the upper side of the filler 200 to support the lateral load between the filler 200 and the filler 200 and to allow a pedestrian to lean on or place an object in the longitudinal direction of the safety fence.
