1 is a view showing the state in which the safety net according to the first embodiment of the present invention is installed, and FIG. 2 is an enlarged perspective view of a part of the safety net according to the first embodiment of the present invention.

Referring to FIGS. 1 and 2, the safety net 100 according to the first embodiment includes a net 10, a support rope 21, a first fixing unit 27, and a second fixing unit 28 ).

The safety net 100 according to the first embodiment is fixedly installed on a wall of a construction site to prevent a worker and an object from falling. The net 10 includes a seed string 12 arranged in the horizontal direction and a blade string 13 arranged in the vertical direction, and forms a grid. The seed line 12 and the blade line 13 may be arranged to intersect approximately vertically, and are fixed to each other at the intersection.

The net 10 includes a first area S1 in which the strings 12 are arranged at a first interval and a second area S2 arranged at a second interval greater than the first interval. A plurality of second regions S2 may be formed in the net 10, and three second regions S2 are formed in the net 10 according to the first embodiment. The second region S2 may be formed in various numbers according to the width of the sheath 12 and the size of the net 10.

The interval between the seed lines 12 in the second region S2 may be 1.5 to 4 times the interval between the seed lines 12 in the first area S1. The present invention is not limited to this, and the spacing between the seed line 12 and the blade line 13 may be made of various structures.

As described above, when the gap between the second regions S2 is formed to be larger than the gap between the first regions S1, the gap between the first regions S1 can be narrowed to prevent the relatively small tool from falling.

The net 10 can be transported and stored in a wound state, and can be cut to an appropriate length at the installation site. The conventional safety net has a problem in that it is difficult to adjust the length because it is manufactured to a predetermined length. Therefore, in a wide place, there was a problem that two safety nets should be used in combination or separately made. However, according to the first embodiment, the length can be easily adjusted simply by cutting the net 10 directly in the field.

Seeds 12 and 13s are polyvinyl chloride (POLYVINYLCHLORIDE, PVC) in a yarn made of any one selected from the group consisting of polyester (POLYESTER), polyethylene (POLYETHYLENE), polypropylene (POLYPROPHILENE), and nylon (NYLON). Or it may be made of a polyurethane (POLYURETHANE) coated structure. When the polyvinyl chloride or polyurethane is coated as described above, the strength of the net can be improved and flame retardancy can be secured.

Hereinafter, the detailed structure of the net 10 will be described in more detail with reference to FIGS. 3 and 4.

3 is a view showing the coupling structure of the net line and the seed line according to the first embodiment of the present invention from the front, and FIG. 4 is a view showing the coupling structure of the net line and the seed line according to the first embodiment of the present invention from the rear This is the drawing.

3 and 4, the seed line 12 and the blade line 13 are divided into a plurality of groups and arranged to intersect, and are fixed by the binding yarn 14 in this state. As illustrated in FIGS. 3 and 4, one seed string 12 and blade string 13 may be formed of yarns divided into five groups. However, the present invention is not limited thereto, and the seeds and the blades may be divided into various numbers.

The seed string 12 and the blade string 13 are fixed by the binding yarn 14, and the coupling yarn 14 is a plurality of first coupling yarns 15 connected in a ring shape and the first coupling yarns 15 adjacent to each other And second coupling yarns 16 which are alternately inserted into and fix the first coupling yarns 15. The first coupling yarn 15 is made of a structure in which the rings are arranged one after another in the longitudinal direction of the first coupling yarn 15.

The first binding yarn 15 may be disposed on the front side of the net 10, and the second binding yarn 16 may be disposed on the rear side of the net 10. In addition, the seed line 12 and the blade line 13 are located between the first coupling yarn 15 and the second coupling yarn 16. The plurality of first coupling yarns 15 and the second coupling yarns 16 are located between the seed cord 12 and the blade 13 and outside the seed string 12 and the blade 13. One second coupling yarn 16 is inserted into a ring portion of two adjacent first coupling yarns 15 to fix the first coupling yarns 15.

The conventional safety net 100 is fixed by stitching the blade line 13 and the seed line 12, or attached using an adhesive or the like. The structure fixed by the lockstitch or the adhesive has a problem that the strength is not only weak but also requires a separate fixing process after the net is manufactured. However, as described above, according to the first embodiment, the blades 13 and the seeds 12 divided into a plurality of groups are fixed in the weaving process by the first binding yarn 15 and the second binding yarn 16. The edge 13 and the seed 12 are stably fixed, so that the strength of the net 10 can be improved.

On the other hand, the support rope 21 is fitted to the net 10 is installed, it is interwoven between the blades 13 so as to abut the opposite surfaces of the adjacent blades (13). That is, the support rope 21 is sandwiched between the blades 13, is inserted in a zigzag form to the blades 13 is coupled to the net (10). When the support rope 21 is coupled to the net 10, the net 10 is cut to a suitable length, and then the support rope 21 is coupled to the net 10 to more easily install the safety net 100. Can be.

At least two or more support ropes 21 are inserted into the net 10, and the support ropes 21 according to the first embodiment are located at the center of the top and bottom of the net 10 and the height direction of the net 10. Each is installed.

The support rope 21 may be formed in the form of a band rope having a width. The support rope 21 has a width greater than that of the blades 13 and 12, and the width of the support ropes 21 may be 3 to 20 times the width of the blades 12 and 13 .

5 is a view showing a state in which the second fixing unit of the safety net according to the first embodiment of the present invention is fixed to the wall, and FIG. 6 is a perspective view showing the first fixing unit according to the first embodiment of the present invention to be.

1, 5, and 6, both ends of the support rope 21 are fixed to the wall 50, and for this purpose, a first fixing unit 27 is provided on one side of the support rope 21. The coupling is installed, and the second fixing unit 28 is coupled to the other side of the support rope 21. Here, the support rope 21 is fixedly installed on the inner surface of the wall 50 as shown in FIG. 1, and accordingly, the safety net 100 may be located in a space between the wall and the wall.

The first fixing unit 27 and the second fixing unit 28 are made of a structure capable of adjusting the length of the support rope 21. In the first embodiment, although the first fixing unit 27 and the second fixing unit capable of adjusting the length are installed at both ends of the supporting rope 21, the present invention is not limited thereto, and the supporting rope 21 ) May be formed to be adjustable in length at only one end.

Since the first fixing unit 27 and the second fixing unit 28 have the same structure, the description of the second fixing unit 28 is replaced by the description of the first fixing unit 27.

To this end, the first fixing unit 27 includes a support frame 271, a winding rod 274, an adjustment wheel 276, and a stopper 277. The support frame 271 includes a first plate portion 271a fixed to the wall 50 and a second plate portion 271b and a third plate portion 271c protruding from both side ends of the first plate portion 271a. The first plate portion 271a is installed to abut against the wall 50, and a fixing member 32 is inserted into the first plate portion 271a. The fixing member 32 may be made of a set anchor or an insert bolt.

The winding rod 274 is located between the second plate portion 271b and the third plate portion 271c, and is rotatably installed with respect to the second plate portion 271b and the third plate portion 271c. The winding rod 274 is formed with a slit 274a into which the support rope 21 is inserted. The slit 274a is formed to extend in the longitudinal direction of the winding rod 274, and when the support rope 21 is inserted into the slit 274a, the support rope 21 is wound around the winding rod 274 according to the rotation of the winding rod 274. ) Can be wound or unwound.

The adjustment wheel 276 is installed on the outer surface of the second plate portion 271b, but is installed to be charged together with the winding rod 274. A plurality of teeth 276a are formed in the adjustment wheel 276, and the teeth 276a are formed such that one side has a greater inclination than the other side. The stopper 277 is installed to be rotatable on the second plate portion 271b and contacts the teeth 276a to control rotation of the adjustment wheel 276. The stopper 277 may be provided with a torsion spring 278 that presses the stopper 277 toward the adjustment wheel.

When the winding rod 274 rotates in the direction of winding the support rope 21, the stopper 277 comes into contact with the surface of the tooth 276a having a small inclination, so that the winding rod 274 can freely rotate, and the support rope When the winding bar 274 rotates in the direction in which the 21 is released, the stopper 277 comes into contact with the surface of the tooth 276a having a large inclination, so that the stopper 277 prevents rotation of the adjustment wheel 276. In this case, the lower end of the stopper 277 is pressed and separated from the teeth 276a, and then the teeth 276a can be rotated.

In the case of using a ratchet buckle, it was not economical, and since the D-type ring and band were fixed with lockstitch and cut to fit the installation length, this had the inconvenience of being manufactured in a place where lockstitch was possible, not in the field. However, as described above, according to the first embodiment, since the first fixing unit 27 and the second fixing unit 28 are installed, the supporting rope 21 cut in the field is the first fixing unit 27 and the second. It is coupled to the fixing unit 28 and the length of the support rope 21 can be easily adjusted. Accordingly, since the support rope 21 and the net 10 can be separated and rolled in a roll shape to be stored and transported, transport and storage are easy.

In addition, according to the first embodiment, since the first fixing unit 27 and the second fixing unit 28 are directly fixedly installed on the wall 50, the first fixing unit 27 and the second fixing unit 28 are provided. By this, the length can be adjusted as well as fixed. In addition, compared to the conventional racket buckle, the first fixing unit 27 and the second fixing unit 28 can be manufactured at a significantly lower cost, thereby reducing costs.

As described above, according to the first embodiment, after cutting the net 10 according to the installation location, the support rope 21 is inserted into the net 10 in a zigzag form, and the support rope 21 is installed. After cutting, the length of the support rope 21 is adjusted with the fixing units 27 and 28, so that the net 10 can be easily installed on the wall. In addition, the relatively large support rope 21 can not only stably support the net 10, but also minimize the size of the hole formed in the net 10 to prevent small objects from falling. When the net and the rope are integrally formed, it is difficult to adjust the length, and there is a limit in strengthening the stiffness of the rope. Therefore, when the net is torn, the strength of the entire safety net decreases.

In addition, when the rope is coupled to the net by a ring or the like, there is a problem that the net and the rope are easily separated or installed by external force. However, as described above, according to the first embodiment, even if the net 10 is torn during operation, it does not affect the rigidity of the support rope 21, and thus it is possible to prevent the worker from falling, as well as the net 10 and The support rope 21 can maintain a stable coupling state.
