Description

Air safety net having dual weaved structure

The present invention relates to an air safety net having a double weave structure, and more particularly, it is installed in various dangerous places such as a construction site, a railroad track, an amusement ride facility, a road or a boundary slope such as a cut, fill, a slope of a hiking trail, etc. It can prevent the worker from falling, and the air buffer structure further improves stability and durability by allowing air rooms to pass or stay in the middle of the double weave structure instead of the existing single weave structure. This is increased, and relates to an air safety net having a double weave structure that can be manufactured integrally to reduce production costs.

In general, at construction sites such as civil works and construction works, or in places such as railroad tracks, knots or weaving with wires or strings, etc. A safety net in the form of a

In addition, safety nets are also installed on boundary slopes such as roads, cuts, fills, and slopes of hiking trails to prevent safety accidents such as falling rocks, falling, or falling of workers.

For example, when cutting the ground made of natural earth layers and rocks or taking the fill on the foundation ground in order to construct a collective building such as railroad and road construction or apartment buildings, a certain part of a mountain slope or hill is cut to open the opening surface. leveling the slope, and the remaining part will have a slope such as a cut slope or a fill slope, and even if the slope of a mountain slope or hill is partially damaged due to a natural disaster such as torrential rain or flood, a certain part of the damaged slope is cut off; A slope will be created in that part.

As such, the slope of the filled or cut area created as a new topography becomes a soft surface. Therefore, if the soft slope is left as it is, the vegetation on the slope easily flows down during the thaw or heavy rain according to the seasonal change and water troughs are formed. There is a high risk of becoming vulnerable or losing, and in severe cases, the surface of the slope collapses, resulting in accidents that cause damage to life and property.

In order to prevent the loss of such a slope, a separate protective structure is installed on the surface of the slope and vegetation is planted to prevent the loss of soil and soil on the slope by greening. There is still the possibility that it will happen.

In the road earthwork process for road construction, after the ground made of rocks is inevitably cut to shape the road surface, structures such as green soil, cornet, soil railing, and fall prevention net are used or vegetation to prevent loss. Blocks are used to protect the slope.

Also, in the case of the slope where the vegetation block is constructed in this way, it is necessary to cover a separate safety net to minimize rockfall.

An example of a safety net according to the prior art is disclosed in Republic of Korea Patent Registration No. 10-0353772 (registered on September 10, 2002, hereinafter referred to as 'Patent Document 1') and the like.

However, since the safety net according to the prior art is provided with a wire rope, the manufacturing cost is greatly increased, and there is a problem that the manufacturing process and the construction process for installation may also be complicated.

In order to solve this problem, even if a safety net is prepared by tying a string made of fiber or resin material, the safety net is not durable because it is a simple single-layer structure. There is a problem that it may not be sufficiently secured.

On the other hand, as shown in Figure 8, the first mesh body 100, the second mesh body 200, and at least the double elastic connection part 300 of the double elastic connection part 300 is a plurality of so that the dust floating in the air is adsorbed to the surface. It is preferable that the dust adsorption holes 320 are formed on the surface.

Accordingly, when the air safety net according to the present invention is installed to cover the load at the construction site or to cover the cut slope, it is possible to prevent the occurrence of a safety accident as well as to prevent dust generated during or after work. It is also possible to prevent the spread of dust to the outside to suppress the spread of scattered dust outdoors, thereby improving the conditions of the working environment.

Here, the dust adsorption hole 320 is formed directly through the mold when the double elastic connection part 300 is molded, or when the double elastic connection part 300 is molded and then cooled to room temperature, the air in the bubble is naturally discharged to the outside, so that the double elastic connection part 300 can be formed by having a porous surface.

On the other hand, as another embodiment of the present invention, as shown in Figure 9, the surface of the double resilient connection part 300, the air that will pass or stay between the first mesh body 100 and the second mesh body 200 A van der Waals adsorption unit 330 is provided with a plurality of carbon nano-processed bristles with a length of about 10 μm and a diameter of about 5 μm so that the dust mixed in the middle is collected by van der Waals adhesion. can make it happen

Accordingly, when fine dust and dust in the vicinity of the air safety net pass through the air safety net, they are collected by the van der Waals adsorption unit 330 to more effectively prevent the diffusion of scattered dust together with the dust adsorption hole 320. can

Here, if the length of the bristles constituting the van der Waals adsorption unit 330 is less than 10 μm, the van der Waals adhesive force may be reduced, and if it exceeds 10 μm, it will rather interfere with the air buffer function by the connection air room 310. Even if the diameter of the bristles is less than 5 μm, van der Waals adhesion may be reduced, and even if it exceeds 5 μm, the air buffer function may be impaired.

On the other hand, as another embodiment of the present invention, as shown in FIG. 10 , graphene ( Graphene) coating layer 400 may be formed.
