Abstract

The present invention relates to a curb stone using waste plastics and, more specifically, to a curb stone using waste plastics which has strengthened deformation resistance, strengthened impact resistance, and price competitiveness. The curb stone is manufactured by a process of injection-molding which uses the mixture sold at a low price, since the mixture is made by mixing and melting waste plastics (such as PP and PE), low-priced vegetable by-products (such as chaff, sawdust, rice husks and wood chips) and heavy waste aggregate; and reinforced by a reinforcement which is inserted therein for corresponding to the strength degradation due to the use of the vegetable by-products.

Description

폐플라스틱을 이용한 도로경계석{Road boundary stone using a waste plastics}Technical Field [0001] The present invention relates to a road boundary stone using waste plastics,

본 발명은 폐플라스틱(PP, PE 등)과 폐골재 및 각종 식물성 부산물(볏집, 톱밥, 왕겨, 목재 파쇄물 등)을 이용하여 도로경계석을 사출성형하여 내변형성과 내충격성을 강화함은 물론 가격경쟁력을 제고하는 기술에 관한 것이다.The present invention relates to a method of injection molding a road barrier using waste plastics (PP, PE, etc.), waste aggregate and various vegetable by-products (straw, sawdust, rice hull, wood crush) It is about technology to improve.

일반적으로 도로와 인도를 구분하기 위해 설치되는 도로경계석은 주로 콘크리트를 사용하여 만든 제품과 화강암을 다듬어 만든 것이 대부분이다.Generally, roadblocks installed to distinguish between roads and roads are made mainly of concrete and granite.

이와 같은 콘크리트 재질의 도로경계석은 가격이 저렴한 장점은 있으나, 내충격성이 떨어지기 때문에 인도를 통행하는 사람들이나 차도를 주행하는 차량과의 충돌 등에 의해서 쉽게 균열을 보이거나 국부적으로 파손되고, 운반 및 설치시에 쉽게 깨지고 손상되어 폐기처리되는 일이 빈번함은 물론 중량이 지나치게 무거워 물류비 및 설치비용이 많이 소요되는 단점이 있다.Such a concrete-type roadway barrier is advantageous in terms of cost, but its impact resistance is poor, so it is easily cracked or locally damaged due to collision with a person traveling in India or a vehicle driving in a roadway, It is often broken, damaged and disposal, and the weight is too heavy, which leads to a disadvantage in that a large amount of logistics and installation costs are required.

또한, 상기와 같이 도로경계석에 균열이나 파손이 발생할 경우 도시의 미관을 해치는 것은 물론 깨진 파편에 의한 사고의 위험성도 있기 때문에 정기적으로 새것으로 교체해야 하는 등 그 유지 및 보수에 있어서 막대한 비용을 지출하고 있다.In addition, if cracks or breakage occur on the road boundary stones as described above, there is a risk of accident due to broken fragments as well as damaging the aesthetics of the city. Therefore, it is necessary to regularly exchange new ones, have.

아울러 상기 도로경계석을 천연 화강암이나 대리석을 사용하기도 하는데, 화강암이나 대리석의 경우 콘크리트에 비해 내구성이 탁월한 장점이 있지만 가격이 매우 고가이기 때문에 그 사용은 매우 제한적이다.Natural granite or marble is used as the road boundary stone. Granite or marble is advantageous in durability compared to concrete. However, its use is very limited because it is very expensive.

상기와 같은 단점을 보완하기 위하여 최근에는 합성수지로 된 도로경계석이 개발되고 있으며, 특히 합성수지 재질의 도로경계석은 폐타이어 및 폐플라스틱과 같은 폐기물의 재활용이 가능하다는 점에서 친환경적이고 제조원가를 어느 정도 낮출 수 있다는 점에서 매우 바람직하다.In order to overcome such disadvantages, recently, a road barrier zone made of a synthetic resin has been developed. In particular, a road barrier zone made of a synthetic resin can be recycled such as waste tires and waste plastics, thus being environmentally friendly, Which is very desirable.

상기 폐플라스틱을 이용한 도로경계석에 관련한 종래의 선행기술로는 「특허공개 제2012-102089호, 명칭/ 폐합성수지를 이용한 합성수지 도로경계석의 제조방법 및 그에 따라 제조되는 합성수지 도로경계석」이 제안되고 있다.As a conventional prior art relating to a road boundary stone using the waste plastic, a method of manufacturing a synthetic resin road boundary stone using the name / a waste synthetic resin and a synthetic resin road boundary stone produced by the method have been proposed in Patent Document No. 2012-102089.

그러나 상기한 선행기술의 도로경계석은 주원료인 폐합성수지와, 이에 함침 또는 스프레이 도포된 페놀수지와, 그리고 폴리우레탄 바인더를 이용하여 제조하고 있으나, 상기 폐합성수지가 전체원료 가운데 대부분을 차지함으로써 현재 지속적인 유가상승으로 인해 기초원료로 쓰이는 재활용 폐플라스틱의 원가도 가파르게 상승함에 따라 제조원가가 높아지고, 상기 페놀수지 및 폴리우레탄 바인더도 매우 고가이므로 가격경쟁력은 더욱 떨어지는 폐단이 있다.However, the above-mentioned prior art roadblocks are produced by using waste synthetic resin as a main material, phenol resin impregnated or sprayed therewith, and polyurethane binder, but since the waste synthetic resin accounts for most of the total raw materials, The cost of recycled waste plastics used as a base material also rises sharply, resulting in an increase in manufacturing cost, and the phenol resin and the polyurethane binder are also very expensive, so that the price competitiveness is further reduced.

또한, 상기 선행기술의 도로경계석은 색상이 한결같아서 색상의 변화를 줄 수 없으며, 따라서 항시 색상이 획일적이고 단순하여 미화적인 측면에서 미약할 수밖에 없는 실정이다.Also, the road barrier seats of the prior art can not change the color because the hues are uniform, and thus the hues are always monotonous, simple, and inevitably weak in terms of beauty.

본 발명은 상기한 종래의 기술에 따른 폐플라스틱을 이용한 도로경계석이 내포하고 있는 제반 문제점을 적극적으로 해소하기 위한 것으로, 상기 폐플라스틱과 저가의 식물성 부산물을 중량물인 폐골재와 함께 혼합하여 용융시킨 혼합원료를 이용하여 제조원가를 대폭 절감하는 도로경계석을 사출성형으로 제조할 수 있도록 하고, 상기 도로경계석의 내부에 보강체를 삽입하여 식물성 부산물의 사용에 따른 강도저하를 충분하게 보강할 수 있도록 함을 발명의 해결과제로 한다.The present invention is to positively solve the problems inherent in the road boundary stones using the waste plastics according to the conventional techniques described above. The waste plastics and the inexpensive vegetable by-products are mixed with the waste aggregate, which is a heavy material, It is possible to manufacture road borders by injection molding which greatly reduces manufacturing cost by using raw materials and inserting reinforcements inside the road borders to sufficiently reinforce the decrease in strength due to the use of plant byproducts As well.

또한, 본 발명은 상기 도로경계석의 외부면을 다양한 색상으로 코팅하여 시인성을 확보함은 물론 외관상의 미려함을 개선할 수 있도록 함을 발명의 해결과제로 한다.The present invention also provides a method for coating a surface of an outer surface of a road barrier with various colors to ensure visibility and to improve appearance.

본 발명은 상기한 과제를 해결하기 위한 수단으로 폐플라스틱과, 식물성 부산물 및 폐골재로 조성된 혼합원료를 이용하여 도로경계석을 사출성형하고, 상기 도로경계석의 내부에 보강체를 삽입 설치하며, 상기 도로경계석의 저면 양측에 한 쌍의 앙카홀더를 일체로 삽입 설치하는 기술을 강구한다.In order to solve the above-mentioned problems, the present invention provides a method of injection molding a road boundary stone by using waste plastics, vegetable by-products and mixed raw materials composed of waste aggregates, inserting a reinforcing member into the road boundary stones, A technique of integrally inserting and installing a pair of anchor holders on both sides of the bottom of the road boundary seats is proposed.

본 발명에 따르면, 고가인 폐플라스틱의 사용량을 일정부분 저가의 식물성 부산물로 대체함으로써 도로경계석의 제조원가를 대폭 절감하여 가격경쟁력을 제고하고, 상기 폐플라스틱 및 식물성 부산물과 함께 중량물인 폐골재가 혼합상태로 일체화 성형됨으로써 상기 폐플라스틱을 사용함에 따른 가벼운 중량으로 인한 안정성 저하를 효율적으로 방지하는 효과를 제공한다.According to the present invention, by replacing the amount of expensive plastic waste with a certain low-cost vegetable by-product, it is possible to significantly reduce the production cost of the road boundary stone, thereby improving price competitiveness, Thereby effectively preventing degradation of stability due to a light weight due to use of the waste plastic.

또한, 상기 폐플라스틱 및 폐골재의 재활용이 가능함으로써 매우 친환경적이며, 상기 도로경계석의 내부에 보강체가 내설됨으로써 식물성 부산물을 사용함에 따른 강도저하를 충분하게 보강하면서 내변형성, 내충격성을 향상하여 내구연한을 증진하는 효과를 제공한다.Further, since the waste plastics and the waste aggregate can be recycled, the reinforcing member is provided inside the road boundary stones. Therefore, the strength degradation due to the use of the vegetable by-products can be sufficiently reinforced while improving the deformation resistance and impact resistance, ≪ / RTI >

또한, 상기 도로경계석의 외부면은 다양한 색상으로 코팅 처리됨으로써 뛰어난 시인성을 확보하여 차량이 도로경계석과 추돌하는 사고발생을 억제함은 물론 도로 바깥쪽의 황색선을 대체하는 효과를 제공하고, 외관이 수려하여 도로주변의 미화환경을 개선하며, 상기 코팅된 표면에 각종 문구나 문양이 표현됨으로써 부수적인 광고효과를 발휘하는 효과를 제공한다.In addition, since the outer surface of the road surface barrier is coated with various colors, excellent visibility can be ensured to prevent the occurrence of an accident that the vehicle collides with a road boundary stone, and an effect of replacing the yellow line outside the road is provided. Thereby improving the beautification environment around the road, and displaying various phrases and patterns on the coated surface, thereby providing an effect of displaying an additional advertising effect.

본 발명이 해결하고자 하는 과제의 해결수단을 보다 구체적으로 구현하기 위한 바람직한 실시 예에 대하여 설명하기로 한다.Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

본 발명의 바람직한 실시 예에 따른 전체적인 기술구성을 첨부된 도면에 의거 개략적으로 살펴보면, 폐플라스틱(11), 식물성 부산물(12) 및 폐골재(13)로 조성된 혼합원료(15)를 이용하여 사출성형되는 몸체(10)와; 상기 몸체(10)의 내부 상하에 삽입 설치된 보강체(20)와; 상기 몸체(10)의 저면 양측에 일체로 삽입 설치된 한 쌍의 앙카홀더의 유기적인 결합구성으로 이루어짐을 알 수 있다.The entire technical construction according to a preferred embodiment of the present invention will be schematically described with reference to the accompanying drawings. In the drawing, a mixed raw material 15 composed of waste plastics 11, vegetable by-products 12, A molded body 10; A reinforcing body (20) inserted in the interior of the body (10); And a pair of anchor holders integrally inserted into both sides of the bottom surface of the body 10.

이하, 상기 개략적인 구성으로 이루어진 본 발명을 실시 용이하도록 좀더 상세하게 설명하기로 한다.Hereinafter, the present invention having the above-described schematic configuration will be described in more detail for facilitating the implementation.

본 발명은 제조원가를 획기적으로 절감하면서도 충분한 강성을 유지하는 신개념의 도로경계석(B)을 제조하기 위한 것으로, 본 발명의 몸체(10)는 통상의 도로경계석과 같은 형태를 유지하되 폐플라스틱(11)(PP, PE 등)과 각종 식물성 부산물(12) 및 폐골재(13)를 포함하는 혼합원료(15)를 이용하여 사출성형을 통해 대량으로 양산하게 된다.The body 10 of the present invention maintains the same shape as that of a conventional road barrier, but the waste plastics 11 are formed in the same manner as the conventional road boundary stones. A large amount is mass-produced through injection molding using a mixed raw material 15 including various kinds of vegetable by-products 12 (PP, PE, etc.), a waste aggregate 13, and the like.

상기 혼합원료(15)는 비교적 고가인 폐플라스틱(11)은 25∼35wt%의 조성비율을 차지하고, 제조원가를 절감하기 위해 상기 폐플라스틱(11)의 사용량을 일부 대체하는 저가의 식물성 부산물(12)은 18∼22wt%의 조성비율을 차지하며, 상기 폐골재(13)는 45∼55wt%의 조성비율을 차지하고, 상기 식물성 부산물(12)은 볏짚, 톱밥, 왕겨, 목재 파쇄물 중 어느 하나를 사용함으로써 도로경계석(B)의 제조원가를 대폭 절감하는 효과를 제공한다.The mixed raw material 15 is a relatively inexpensive vegetable by-product 12 that partially replaces the used amount of the waste plastic 11 in order to reduce the production cost and occupy a composition ratio of 25 to 35 wt% , The waste aggregate (13) occupies a composition ratio of 45 to 55 wt%, and the plant by-product (12) is one of rice straw, sawdust, rice hull, The manufacturing cost of the road boundary stone (B) is significantly reduced.

이때 상기 폐골재(13)는 상기 폐플라스틱(11)과 식물성 부산물(12)만을 사용하여 도로경계석을 제조하는 경우 가벼운 중량으로 인한 안정성 저하의 단점을 방지하기 위한 것으로, 충분한 중량감을 제공하면서도 골재처리장에서 버려지는 폐골재(13)를 수거하여 사용함으로써 제조원가를 절감할 수 있게 된다.At this time, the waste aggregate (13) is used to prevent the disadvantage of reduction in stability due to light weight when the roadside slab is manufactured using only the waste plastic (11) and the vegetable by-product (12) It is possible to reduce the manufacturing cost by collecting and discarding the discarded aggregate material 13 from the plant.

상기 몸체(10)의 내부에는 상하 이격된 상태로 한 쌍의 보강체(20)가 내설되는 신규의 기술이 접목되고, 상기 보강체(20)는 원가절감을 위해 강도가 약한 식물성 부산물(12)을 사용함에 따라 그만큼 저하된 강도를 보강하는 역할을 수행하며, 상기 보강체(20)는 구체적으로 와이어메쉬나 FRP(섬유강화플라스틱)를 원소재로 제작한 망체가 적용될 수 있게 된다.A new technique for inserting a pair of reinforcing members 20 in a state of being vertically spaced apart is incorporated in the body 10. The reinforcing member 20 is made of vegetable by-products 12 having a weak strength for cost reduction, The reinforcing member 20 can be applied to the reinforcing member 20 made of wire mesh or FRP (fiber reinforced plastic) as a raw material.

또한, 상기 몸체(10)의 저면에는 양측에 각각 한 쌍의 앙카홀더(30)가 외부로 노출하게 일체로 삽입 설치되고, 상기 앙카홀더(30)는 하측으로 개방된 나사부(31)가 형성됨으로써 상기 나사부(31)에 앙카볼트(35)를 간편하게 결합하여 도 1과 같이 지중에 타설되는 기초콘크리트(1)에 앙카볼트(35)를 매설하여 상기 도로경계석(B)을 안전시공함은 물론 상기 앙카홀더(35)가 몸체(10)에 일체로 구성됨으로써 시공시간을 단축할 수 있게 된다.In addition, a pair of anchor holders 30 are integrally inserted into the bottom surface of the body 10 so as to be exposed to the outside, and the anchor holder 30 has a threaded portion 31 opened downward The anchor bolts 35 are easily connected to the threaded portions 31 so that the anchor bolts 35 are buried in the foundation concrete 1 laid in the ground as shown in FIG. 1 to safely construct the road boundary stone B, Since the anchor holder 35 is integrally formed with the body 10, the construction time can be shortened.

아울러 상기 몸체(10)의 저면 가운데 상기 앙카홀더(30)의 사이에는 격자상으로 다수의 지반지지력 보강홈(40)이 추가로 함몰 형성되고, 상기 지반지지력 보강홈(40)에는 지중에 타설되는 기초콘크리트(1)가 삽입 상태로 타설됨으로써 상기 기초콘크리트(1)와 도로경계석(B)은 일체성을 유지하여 더욱 견고한 지반지지력을 제공할 뿐만 아니라 혼합원료(15)를 절감하는 효과를 제공한다.A plurality of ground supporting force reinforcement grooves 40 are further formed in a grid shape between the anchor holder 30 and the ground supporting force reinforcement grooves 40, Since the foundation concrete 1 is inserted in the inserted state, the foundation concrete 1 and the road boundary stone B maintain the integrity so as to provide a stronger ground supporting force and also to reduce the mixed raw material 15 .

상기 몸체(10)의 외부면에는 색상처리된 코팅재(50)가 도포되거나 다양한 색상처리된 코팅시트(50a)가 열융착을 통해 일체화 감싸게 설치된다.A color coated coating material 50 is coated on the outer surface of the body 10 or a coated color coated coating sheet 50a is installed on the outer surface of the body 10 by thermal fusion.

따라서, 상기 도로경계석(B)은 인도와 도로의 경계선임을 강조하기 위해 식별력이 확연한 색상으로 하게 되면 시인성이 뛰어나 차량이 도로경계석(B)과 추돌하는 사고나 행인이 인도의 바깥으로 넘어가는 것에 대한 경계 효과가 매우 크고, 미화적인 측면에서도 매우 효과적이며, 나아가 상기 코팅재(50) 및 코팅시트(50a)의 표면에는 다양한 문양이나 문구를 표현함으로써 우수한 광고효과를 부수적으로 제공할 수도 있다.Therefore, the road boundary stone B is excellent in visibility if the distinctive color is made distinctive in order to emphasize that it is the boundary between the road and the road, so that an accident in which the vehicle collides with the road boundary stone (B) The boundary effect is very large, and it is very effective also in terms of beautification. Further, by expressing various patterns or phrases on the surface of the coating material 50 and the coating sheet 50a, it is possible to provide an excellent advertising effect incidentally.

상기 도로경계석(B)은 길이방향으로 인접하는 다른 도로경계석(B)과 일체로 연결하기 위한 기술구성이 추가로 접목된다.The road boundary stone B is further combined with a technical construction for integrally connecting the road boundary stone B with another road boundary stone B adjacent in the longitudinal direction.

이를 위해 상기 몸체(10)의 양 측면에는 도 6과 같이 커넥팅홀(60)이 각각 형성되고, 상기 커넥팅홀(60)에는 몸체(10)를 길이방향으로 일체화 연결하기 위한 커넥터(61)가 끼움 결합됨으로써 우수한 시공성을 확보할 수 있게 된다.
A connecting hole 60 is formed on both sides of the body 10 as shown in FIG. 6 and a connector 61 for connecting the body 10 in the longitudinal direction is fitted into the connecting hole 60. And thus it is possible to ensure excellent workability.

한편, 본 발명의 도로경계석(B)은 아래와 같은 제조방법을 통해 제조될 수 있게 된다.On the other hand, the road boundary stone (B) of the present invention can be produced by the following production method.

[제조방법][Manufacturing method]

폐플라스틱(11)과 식물성 부산물(12)을 각각 구분하여 파쇄한 후 상기 파쇄된 폐플라스틱(11) 25∼35wt%와, 식물성 부산물(12) 18∼22wt%와, 폐골재(13) 45∼55wt%를 골고루 혼합하여 혼합원료(15)를 만든다.The waste plastic 11 and the vegetable by-product 12 are separated and crushed, and then 25 to 35 wt% of the crushed waste plastic 11, 18 to 22 wt% of the vegetable by-product 12, And 55wt% are evenly mixed to prepare a mixed raw material (15).

상기 혼합원료(15)를 용융기에 투입하여 고온 가열하면서 일체로 용융한다.The mixed raw material (15) is put into a melting machine and is melted integrally while heating at a high temperature.

하부금형의 내부에 상기 보강체(20) 및 앙카홀더(30)를 배치한다.The reinforcing member 20 and the anchor holder 30 are disposed inside the lower mold.

상기 용융된 혼합원료(15)를 하부금형의 내부에 주입한 후 상부금형을 프레싱하여 상기 보강체(20) 및 앙카홀더(30)가 일체로 내설된 몸체(10)를 사출성형한다.The molten mixed material 15 is injected into the lower mold and the upper mold is pressed to injection-mold the body 10 in which the reinforcing member 20 and the anchor holder 30 are integrated.

이와 같이 사출성형된 본 발명의 도로경계석(B)은 내변형성과 내충격성이 매우 우수하면서도 종래의 도로경계석에 비해 제조원가를 대폭 절감할 수 있어 가격경쟁력을 높일 수 있는 효과를 제공함은 자명하다고 할 수 있다.It is obvious that injection-molded roadside bark (B) of the present invention which is injection-molded as described above has an excellent resistance to internal deformation and impact resistance, but can significantly reduce manufacturing cost compared to conventional roadside bushes, have.
