본 발명은 건축용 수직보호망 및 낙하물방지망과 그 제직공정에 관한 것으로서, 보다 상세하게는 경량이면서 인장강도와 신축성이 우수하고, 안전사고와 화재 및 환경오염을 방지함과 동시에, 재활용이 가능하며, 제조비용과 설치비용이 절감되는 건축용 수직보호망 및 낙하물방지망과 그 제직공정에 관한 것이다. The present invention relates to a vertical protection net for building and fall prevention net and a weaving process thereof. More specifically, it is lightweight, has excellent tensile strength and elasticity, prevents safety accidents, fire and environmental pollution, and is recyclable. The present invention relates to a vertical protection net for construction and a falling-prevention net, and a weaving process thereof, in which cost and installation cost are reduced.

일반적으로 고층 건물의 신축 현장 등과 같은 건축현장에서는 고소작업 중 목제, 비계, 작업도구 및 현장자재 등의 낙하를 방지하기 위해서, 시공 중인 건축물의 외벽에 도 1 및 도 2에 도시된 바와 같이, 수직 및 수평으로 수직보호망 및 낙하물방지망(101)을 설치한다. In general, in construction sites such as new construction sites of high-rise buildings, in order to prevent falling of wood, scaffolding, work tools, and field materials during high-rise work, as shown in FIGS. 1 and 2, And horizontally install a vertical protection net and falling object prevention net (101).

이러한 수직보호망 및 낙하물방지망은 낙하물에 의해 찢어지지 않는 인장강도와 낙하물의 충격을 흡수할 수 있는 충분한 신축성, 그리고, 화재 예방을 위한 방염성능을 가지고 있어야 한다. Such vertical protection nets and drop protection nets shall have tensile strength not to be torn by falling objects, sufficient elasticity to absorb the impact of falling objects, and flame retardant performance for fire prevention.

한편, 종래 수직보호망 및 낙하물방지망은 P.V.C코팅망 또는 폴리에틸렌 섬유나 폴리프로필렌 섬유로 이루어진 소재를 사용하여 제조되었다. On the other hand, the conventional vertical protection net and fall prevention net was manufactured using a P.V.C coating net or a material made of polyethylene fibers or polypropylene fibers.

이 중 P.V.C코팅망은 고가이면서 인장강도가 약해서 낙하물에 의해 잘 찢어지고, 신축성이 없어 설치가 용이하지 않을뿐더러, 산업폐기물로서 다이옥신 등의 발암물질이 발생하고 분진을 차단하지 못하여 환경오염을 야기하는 문제점이 있었다. Among them, PVC coating network is expensive and weak in tensile strength, so it is easily torn by falling objects, and it is not easy to install due to its elasticity.In addition, carcinogens such as dioxin are generated as industrial waste and it does not block dust, causing environmental pollution. There was a problem.

그리고, 폴리에틸렌 섬유의 경우에는 가격이 저렴하다는 이유에서 수직보호망 및 낙하물방지망 소재로 많이 이용되고 있으나, 충격흡수력과 인장강도가 약해서 찢어지거나 파손되어 낙하물에 의해 많은 사고가 발생하는 문제점이 있었다. In addition, in the case of polyethylene fiber, because of the low price, it is widely used as a vertical protection net and a drop preventing material, but the shock absorbing force and the tensile strength is weak, there is a problem that a lot of accidents due to the torn or broken due to the fall.

또한, 폴리프로필렌 섬유의 경우에는 수직보호망 및 낙하물방지망 원단을 제직한 후 후방염처리가공을 하여 방염성능을 부여하였으나, 후방염처리가공은 방염액의 과다 사용 및 조직도의 조밀화에 의해 수직보호망 및 낙하물방지망의 중량이 무거워지는 문제점이 있었다. In addition, in the case of polypropylene fiber, after weaving the vertical protection net and the drop prevention net fabric, the flame retardant performance was imparted to the flame retardant treatment. There was a problem that the weight of the protection net is heavy.

이에 따라, 무거운 중량에 의해 수직보호망 및 낙하물방지망의 설치가 용이하지 못하게 되며, 중량을 줄이기 위하여 수직보호망 및 낙하물방지망 조직도를 비교적 넓게 편직하는 경우에는 수직보호망 및 낙하물방지망의 인장강도가 저하되는 문제점이 발생하였다. 또한, 후방염처리가공의 경우에는 방염액에 의한 끈적임이 발생하고, 끈적임에 의해 이물질이 묻어 수직보호망 및 낙하물방지망을 오염시키 며, 방염 작업 과정에서 DMF 및 발암물질 등의 유해물질 발생과 유독성이 강한 냄새가 발생하여 작업자의 건강과 안전을 저해하고, 환경유해물질이 발생하는 문제점이 있었다. Accordingly, the installation of the vertical protection net and the drop protection net is not easy due to the heavy weight, and when the vertical protection net and the drop protection net organization chart are relatively wide in order to reduce the weight, there is a problem that the tensile strength of the vertical protection net and the drop prevention net decreases. Occurred. In addition, in the case of the back salt treatment, stickiness is caused by the flame retardant solution, and foreign substances are adhered by the stickiness to contaminate the vertical protection net and the fall prevention net. There is a problem that a strong smell occurs to hinder the health and safety of workers, and environmentally harmful substances occur.

따라서, 본 발명의 목적은 경량이면서 인장강도와 신축성이 우수하고, 안전사고와 화재 및 환경오염을 방지함과 동시에, 재활용이 가능하며, 제조비용과 설치비용이 절감되는 건축용 수직보호망 및 낙하물방지망과 그 제직공정을 제공하는 것이다. Therefore, the object of the present invention is lightweight, excellent in tensile strength and elasticity, while preventing safety accidents and fire and environmental pollution, at the same time, can be recycled, construction vertical protection nets and fall prevention nets and manufacturing costs and installation costs are reduced and It is to provide the weaving process.
