본 고안은 콘크리트 또는 아스팔트로 타설된 바닥의 상부에 형성된 폐타이어 고무칩상에 우레탄 액상을 도포하여 다목적 구장을 시공하는 우레탄 액상을 이용한 플렉스텝 복층 탄성 다목적 구장에 관한 것으로, 특히, 콘크리트 등의 기층 상부에 보강 섬유가 혼합된 폐타이어 고무칩을 형성하고, 이 형성된 폐타이어 고무칩 상부에 홈을 형성한 후, 우레탄 액상을 도포함으로써 폐타이어 고무칩과 우레탄 액상이 분리되는 것을 방지하는 우레탄 액상을 이용한 플렉스텝 복층 탄성 다목적 구장에 관한 것이다.The present invention relates to a flex-step multi-layer elastic multi-purpose stadium using urethane liquid to apply a liquid urethane to a waste tire rubber chip formed on the floor of concrete or asphalt, and in particular, to the top of a substrate such as concrete. Using the urethane liquid to form a waste tire rubber chip mixed with reinforcing fibers, and to form a groove on the formed waste tire rubber chip, and to apply a urethane liquid to prevent separation of the waste tire rubber chip and the urethane liquid Plexstep multi-layer elastic multi-purpose ball.

일반적으로, 산업이 고도로 발달하면서 폐타이어 등의 고체폐기물이 증가하여 환경오염은 물론 폐기물을 처리하는데 상당한 비용이 소요된다. 특히, 이러한 폐기물의 처리는 사회적인 문제로 대두되어 쾌적한 환경을 만들기 위해 친환경적인 기능물이 개발되어 오고 있다.In general, as the industry is highly developed, solid wastes such as waste tires are increased, and a considerable cost is required to treat wastes as well as environmental pollution. In particular, the disposal of such waste is a social problem, and environmentally friendly functions have been developed to create a pleasant environment.

종래에는 농구장 등의 다목적 구장의 바닥을 시공하기 위해서 도 1에 도시된 바와 같이, 평평하게 처리된 콘크리트 또는 아스콘 등의 기층(1) 상부에 프라이머(2)를 도포하고, 그 프라이머(2)의 상부에 1차로 경화제를 혼합한 반경질의 우레탄 액상(3)을 도포한 후에, 마지막으로 그 위에 경질의 우레탄 액상(4)을 2차로 도포함으로써, 탄성 바닥재를 형성하는 방식이 사용되어 오고 있다.Conventionally, in order to construct the floor of a multi-purpose stadium such as a basketball court, as shown in FIG. 1, the primer 2 is applied to the base layer 1, such as flat concrete or asphalt concrete, and the primer 2 The method of forming an elastic flooring material has been used by apply | coating the semi-hard urethane liquid 3 which mixed the hardening | curing agent on the upper part first, and finally apply | coating a hard urethane liquid 4 on the secondary.

그러나, 종래의 탄성 바닥재를 이용하여 다목적 구장의 바닥을 시공하는 경우, 우레탄 액상이 시간이 지남에 따라 밀림 현상 및 뒤틀림 현상 등이 발생하여 프라이머와 우레탄 액상이 분리되는 현상이 야기되었다.However, when constructing the bottom of the multi-purpose stadium using a conventional elastic flooring, the urethane liquid is caused by the phenomena such as the sliding phenomenon and the warping phenomenon over time, causing the phenomenon that the primer and the urethane liquid is separated.

또한, 종래의 탄성 바닥재는 콘크리트 등의 기층 상부에 바로 우레탄 액상만을 도포하기 때문에, 기층의 표면이 반드시 평평해야 하는 어려움과 바닥면상에 존재하는 탄성력이 부족한 단점이 있다.In addition, the conventional elastic flooring material has a disadvantage in that the surface of the base layer must be flat, and the elastic force present on the floor surface is insufficient because it only applies the urethane liquid directly to the base layer, such as concrete.

따라서, 본 고안은 상기한 문제점을 감안하여 안출된 것으로, 다목적 구장의 바닥 시공시에 콘크리트 및 아스콘 등의 기층 표면에 도포된 프라이머의 상부에 보 강 섬유가 혼합된 고무칩을 형성함으로써, 울퉁불퉁한 기층에서도 직접 형성이 가능한 동시에 증가된 탄성력을 가질 수 있고, 이 고무칩에 일정한 간격으로 홈을 만들어 우레탄 액상과 고무칩 사이에 결합력이 좋아지도록 하는 우레탄 액상을 이용한 플렉스텝 복층 탄성 다목적 구장을 제공하는 것이다.Therefore, the present invention has been devised in view of the above problems, by forming a rubber chip mixed with reinforcing fibers on top of the primer applied to the base surface of concrete and asphalt concrete at the time of floor construction of the multi-purpose stadium, It is possible to form directly in the base layer and at the same time have an increased elastic force, and to provide a flex-step multilayer elastic multi-purpose stadium using a urethane liquid to improve the bonding force between the urethane liquid and the rubber chip by making grooves in the rubber chip at regular intervals. will be.

상기와 같은 목적을 달성하기 위해, 본 고안은 기층의 상부에 형성된 프라이머층을 가지는 우레탄 액상을 이용한 플렉스텝 복층 탄성 다목적 구장에 있어서, 상기 프라이머층의 상부에 고무칩이 포설되는 동시에 상기 고무칩의 인장 강도를 강화하기 위한 보강 섬유가 혼합되어 있는 고무칩 탄성층과, 상기 고무칩 탄성층의 상부 표면에 도포되는 우레탄 실링층과, 상기 실링층의 상부에 우레탄 액상이 도포되는 제 1우레탄 도포층과, 상기 제 1우레탄 도포층 상부에 우레탄 액상이 코팅되는 제 2우레탄 수지층을 포함하고, 상기 고무칩 탄성층은 둘레 주위에 상기 우레탄 액상을 주입하도록 홈을 가지는 구성이다.In order to achieve the above object, the present invention is a flex-tap multi-layer elastic multi-purpose ballet using a urethane liquid having a primer layer formed on the base layer, the rubber chip on the top of the primer layer at the same time of the rubber chip A rubber chip elastic layer containing a mixture of reinforcing fibers for reinforcing tensile strength, a urethane sealing layer applied to the upper surface of the rubber chip elastic layer, and a first urethane coating layer coated with a urethane liquid on the sealing layer. And a second urethane resin layer coated with a urethane liquid on the first urethane coating layer, wherein the rubber chip elastic layer has a groove to inject the urethane liquid around the perimeter.

또한, 상기 고무칩에 대한 상기 보강 섬유의 혼합 중량비는 100 대 0.5인 것이 바람직하다.In addition, the mixing weight ratio of the reinforcing fibers to the rubber chip is preferably 100 to 0.5.

또한, 상기 홈은 10 ~ 15cm인 것이 바람직하다.In addition, the groove is preferably 10 ~ 15cm.

이하, 본 고안에 따른 구성 및 작용효과를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the configuration and effect according to the present invention in detail as follows.

도 2은 본 고안에 따른 우레탄 액상을 이용한 우레탄 액상을 이용한 플렉스텝 복층 탄성 다목적 구장의 단면도이다. 도 2에 도시된 바와 같이, 먼저 콘크리트 및 아스콘 등의 기층(10) 표면에 프라이머(11)를 도포한다. 여기서, 프라 이머(11)는 0.3 ~ 0.5kg/m2 으로 균일하게 도포하고, 도포 후 장시간이 경과하지 않도록 하는 것이 바람직하다.Figure 2 is a cross-sectional view of a flex-step multilayer elastic multi-purpose ball using a urethane liquid using a urethane liquid according to the present invention. As shown in Figure 2, first, the primer 11 is applied to the surface of the base layer 10, such as concrete and asphalt concrete. Here, it is preferable that the primer 11 is uniformly applied at 0.3 to 0.5 kg / m 2 , and the long time does not pass after the application.

그 다음, 도포된 프라이머(11)의 상부 표면에 다각형의 망구조를 갖는 보강 섬유(21)와 고무칩(페타이어)(20)이 혼합된 고무칩 탄성층(12)을 형성한다. 이 고무칩 탄성층(12)을 형성함으로 인해, 울퉁불퉁 하거나 돌기를 가진 기층에도 본 고안의 플렉스텝 복층 탄성 다목적 구장을 제조하는 것이 가능하고, 보다 증가된 탄성력을 갖는 다목적 구장의 바닥면을 시공할 수 있다.Next, a rubber chip elastic layer 12 in which a reinforcing fiber 21 having a polygonal network structure and a rubber chip (fetter tire) 20 is mixed is formed on the upper surface of the applied primer 11. By forming the elastic layer 12 of the rubber chip, it is possible to manufacture the flex-tap multi-layer elastic multi-purpose stadium of the present invention even on a bumpy or protruding substrate, and to construct the bottom surface of the multi-purpose stadium with increased elastic force. Can be.

여기서, 보강 섬유(21)를 사용하는 이유는 고무칩(20)에 가해지는 외부 마찰력 등에 대한 인장 강도의 향상 및 뒤틀림 현상이나 찢어지는 등의 현상을 억제할 수 있다. 또한, 마모, 피로 하중에 대한 저항력이 증대되고, 휨강도 및 동결 융해 저항력이 증대한다. 따라서, 본 고안의 플렉스텝 복층 탄성 다목적 구장에 있어서, 균열방지에 의한 내구성을 극대화할 수 있다.Here, the reason for using the reinforcing fibers 21 can be to improve the tensile strength against the external frictional force applied to the rubber chip 20, and to prevent the phenomenon such as distortion or tearing. In addition, resistance to wear and fatigue load is increased, and bending strength and freeze-thawing resistance are increased. Therefore, in the FlexTap multi-layer elastic multi-purpose stadium of the present invention, durability by crack prevention can be maximized.

또한, 고무칩(20)에 대한 보강 섬유(21)와의 혼합 중량비는 고무칩(20)에 대해 보강 섬유(21)를 대략 100 대 0.5로 혼합하면 인장력 등의 강도를 증가시킬 수 있다.In addition, the mixing weight ratio of the rubber chip 20 with the reinforcing fiber 21 may increase the strength of the tensile force or the like by mixing the reinforcing fiber 21 with respect to the rubber chip 20 at about 100 to 0.5.

아래와 같이, 보강 섬유의 특성을 표 1에 나타낸다.As shown below, the properties of the reinforcing fibers are shown in Table 1.

재질material Homopolymer PolypropyleneHomopolymer Polypropylene 비중importance 0.910.91 용융점Melting point 162℃162 ℃ 내산성Acid resistance 아주 높음Very high 내알카리성Alkali resistance 아주 높음Very high 인장강도The tensile strength 3500 ~ 7700kgf/㎠3500 ~ 7700kgf / ㎠ 탄성계수Modulus of elasticity 35 × 103kgf/㎠35 × 10 3 kgf / ㎠

또한, 이 보강 섬유와 고무칩을 경화하기 위해 바인더(미도시)를 첨가제로 사용하는 것이 바람직하다.In addition, it is preferable to use a binder (not shown) as an additive to cure the reinforcing fibers and rubber chips.

그 다음, 기공을 매우기 위한 우레탄 실링층(13)을 형성하기 전에, 도 3 및 도 4에 도시된 바와 같이, 고무칩 탄성층(12)의 둘레에 직경 10 ~ 15cm의 구멍을 가진 홈(19)을 형성함으로써, 이후에 기술될 반경질의 우레탄 액상(22)을 부을 때, 이 홈(19)으로 반경질의 우레탄 액상(22)이 주입된다. 이로 인해, 고무칩 탄성층(12)과 제 1탄성층(14)과의 결합력을 증가시켜서 고무칩(20)하고 반경질의 우레탄 액상(22)이 분리되는 것을 막을 수 있다.Then, before forming the urethane sealing layer 13 for forming pores, as shown in Figs. 3 and 4, the groove having a hole having a diameter of 10 to 15cm around the rubber chip elastic layer 12 ( By forming 19, when pouring a semi-curable urethane liquid 22 to be described later, a semi-cured urethane liquid 22 is injected into this groove 19. As a result, the rubber chip 20 and the urethane liquid 22 having a radius can be separated from each other by increasing the bonding force between the rubber chip elastic layer 12 and the first elastic layer 14.

이 홈을 형성한 후, 고무칩 탄성층(12)이 경화되기 전에, 고무칩 탄성층(12)의 상부에 우레탄 실링층(13)을 형성한다. 이 우레탄 실링층(13)은 고무칩(20)끼리 섞이는 과정에서 생긴 기공을 막아주는 역할을 하고, 이 기공이 남아 있지 않도록 고무칩 시공 표면에 충분한 양을 10 ~ 15분 이내에 도포하는 것이 바람직하다. 비록, 우레탄 실링층(13)이 고무칩 탄성층(12)의 상부에 형성되지만, 고무칩 탄성층(12)의 홈(19)은 둘레 주위에 직경 10 ~ 15cm의 구멍을 그대로 형성하고 있다.After the groove is formed, the urethane sealing layer 13 is formed on the rubber chip elastic layer 12 before the rubber chip elastic layer 12 is cured. The urethane sealing layer 13 serves to prevent pores generated during the mixing of the rubber chips 20, and it is preferable to apply a sufficient amount to the surface of the rubber chip construction within 10 to 15 minutes so that the pores do not remain. . Although the urethane sealing layer 13 is formed on the rubber chip elastic layer 12, the grooves 19 of the rubber chip elastic layer 12 form holes having a diameter of 10 to 15 cm around the periphery.

그 다음, 우레탄 실링층(13)의 상부에 반경질의 우레탄 액상(22)이 도포된 제 1우레탄 도포층(14)을 형성한다. 이 반경질의 우레탄 액상(22)이 우레탄 실링층이 도포된 고무칩 탄성층(12)의 홈(19) 사이로 들어감으로써, 결합력이 증가되어 고무칩(20)과 우레탄 액상(22)이 분리되는 것을 방지할 수 있다.Next, the first urethane coating layer 14 having the urethane liquid liquid 22 coated thereon is formed on the urethane sealing layer 13. This semi-urethane urethane liquid 22 enters the grooves 19 of the rubber chip elastic layer 12 to which the urethane sealing layer is applied, whereby the bonding force is increased so that the rubber chip 20 and the urethane liquid 22 are separated. It can prevent.

따라서, 보강 섬유(21)와 고무칩(페타이어)(20)이 혼합된 고무칩 탄성층(12)을 형성함으로써, 어떤 지층의 표면에도 탄성 다목적 구장을 시공하는 것이 가능하고, 고무칩 탄성층(12)에 구멍을 갖는 홈을 형성함으로써, 제 1우레탄 도포층(14)과 고무칩 탄성층(12)의 결합력을 증가시킬 수 있다.Therefore, by forming the rubber chip elastic layer 12 in which the reinforcing fibers 21 and the rubber chip (fetter tire) 20 are mixed, it is possible to construct an elastic multi-purpose ball on the surface of any layer, and the rubber chip elastic layer By forming a groove having a hole in (12), the bonding force between the first urethane coating layer 14 and the rubber chip elastic layer 12 can be increased.

마지막으로, 제 1우레탄 도포층(14) 상부에 경질의 우레탄 액상(23)이 코팅되는 제 2우레탄 수지층(15)을 형성한다. 이 경질의 우레탄 액상(23)은 0.3mm 정도의 두께가 바람직하며, 제 1우레탄 도포층(14)의 표면 기포 및 표면 굴곡 등을 정리하는데 이용된다.Finally, the second urethane resin layer 15 on which the hard urethane liquid 23 is coated is formed on the first urethane coating layer 14. The hard urethane liquid 23 is preferably about 0.3 mm thick and is used to clean up surface bubbles, surface curvatures, and the like of the first urethane coating layer 14.

이상에서 상세히 설명한 바와 같이, 본 고안은 보강 섬유와 고무칩이 혼합된 고무칩 탄성층을 형성함으로써, 어떤 지층의 표면에도 탄성 다목적 구장을 시공하는 것이 가능하고, 고무칩 탄성층에 구멍을 갖는 홈을 형성함으로써, 고무칩과 우레탄 액상의 결합력을 증가시키고, 서로 분리되는 것을 방지할 수 있다.As described in detail above, the present invention forms a rubber chip elastic layer in which reinforcing fibers and rubber chips are mixed, so that it is possible to construct an elastic multi-purpose ball on the surface of any strata, and a groove having a hole in the rubber chip elastic layer. By forming a, it is possible to increase the bonding force between the rubber chip and the urethane liquid, and to prevent separation from each other.
