Description

이중보도블록{A foot-path block having a springy surface}Double footpath block {A foot-path block having a springy surface}

본 고안은 이중보도블록에 관한 것으로서, 보다 구체적으로는 시멘트배합물을 주성분으로 하는 콘크리트 기층과, 폐타이어 고무칩이나 폐우레탄칩과 같은 탄성칩을 주성분으로 하는 탄성표층이 견고하게 결합되어 있는 이중보도 블록에 관한 것이다.The present invention relates to a double sidewalk block, and more specifically, a double sidewalk that is firmly coupled with a concrete base layer composed mainly of cement compounds and an elastic surface layer composed mainly of elastic chips such as waste tire rubber chips or waste urethane chips. It's about blocks.

이중보도블록에 관한 종래기술로는 대한민국 특허 제 0130603 호, 특허 제 0131052 호 및 특허 제 0172473 호와 특허공개번호 제 2001-0110270 호 등을 들 수 있다.Conventional technologies related to double sidewalk blocks include Korean Patent No. 0130603, Patent No. 0131052, Patent No. 0172473, and Patent Publication No. 2001-0110270.

특허 제 0130603 호는 경량, 투수성 보도블록에 관한 것으로서, 입경10㎜이내인 SiO2함유 연소재 응고물 60~90중량%, 폐유리 5~20중량%, 물유리 5~20중량%로구성되며 1,100 ~ 1,200℃의 온도에서 소성된 기층부와, 입경 3㎜이내인 도석 또는 점토재질과 페유리 또는 물유리로 구성되는 표층부로 구성된 것으로서 기층부와 폐층부를 순차적으로 금형에 넣고 1,100 ~ 1,200℃의 온도에서 소성시켜 기층부를 구성하는 입자를 부분용융시키는 것이었기 때문에 충격에 취약하고 반발탄성에 의한 완충효과를 얻을 수 없었었으며, 고온의 열처리를 요하는 것이 었기 때문에 제조비용이 많이드는 등의 문제점이 있었다.Patent No. 0130603 relates to a lightweight, permeable sidewalk block, consisting of 60 to 90% by weight of SiO 2 containing combusted coagulant having a particle diameter of 10 mm, waste glass 5 to 20% by weight, and water glass 5 to 20% by weight. It is composed of a base layer section fired at a temperature of 1,100 ~ 1,200 ℃, and a surface layer section consisting of pottery or clay material with a particle diameter of less than 3mm and pew glass or water glass. Partial melting of the particles constituting the base portion by firing at the part prevented the shock-absorbing and buffering effect due to the rebound elasticity, and the high temperature heat treatment required the manufacturing cost. .

그리고 특허 제 0131052 호는 경량, 투수성 보도 블록에 관한 것으로서 입경 10㎜이내인 플라이 애쉬 응고물 입자 60 ~ 80중량%와, 입경이 1㎜이내인 폐유리 20 ~ 40중량%로 구성되는 하층부와, 입경 3㎜이내인 도석 또는 점토입자의 소성물에 유약처리한 표층부로 구성된 것이었기 때문에 상기 특허 제 0130603 호와 동일한 문제점이 있었다.Patent No. 0131052 relates to a lightweight, permeable sidewalk block, comprising a lower layer composed of 60 to 80% by weight of fly ash solidified particles having a particle diameter of 10 mm or less, and 20 to 40% by weight of waste glass having a particle size of 1 mm or less. , Having a surface layer portion glazed to a fired product of a pottery or clay particle having a particle diameter of 3 mm or less, has the same problem as in Patent No. 0130603.

그리고 특허 제 0172473 호는 폐타이어 재활용 고무보도블록에 관한 것으로서 폐타이어 분말 100중량부, 라텍스바인더 5 ~ 20중량부 및 가황제 2 ~ 7중량부를 함유하는 보도블록 하층부와, 폐에틸렌프로필렌 고무분말 100중량부, 안료 1 ~ 3중량부, 라텍스바인더 5 ~ 20중량부 및 가황제 2 ~ 7중량부를 함유하는 보도블록 상층부로 구성되며, 상층부와 하층부의 두께비를 1:1.5 ~ 2의 비율로 하여서 된 것이었고, 특허공개번호 제 2001-0110270호는 폐플라스틱 재이용 이중보도블록에 관한 것으로서 합성고무층으로 형성된 상층부와, 플라스틱 또는 폐플라스틱으로 형성된 하층부로 구성된 것이었다.In addition, Patent No. 0172473 relates to waste tire recycled rubber foot block, which includes 100 parts by weight of waste tire powder, 5 to 20 parts by weight of latex binder, and 2 to 7 parts by weight of vulcanizing agent, and waste ethylene propylene rubber powder 100 It is composed of the upper part of the sidewalk block containing 1 part by weight, 1 to 3 parts by weight of pigment, 5 to 20 parts by weight of latex binder, and 2 to 7 parts by weight of vulcanizing agent. Patent Publication No. 2001-0110270 relates to a waste plastic reuse double sided block consisting of an upper layer formed of a synthetic rubber layer and a lower layer formed of plastic or waste plastic.

이와 같은 이중보도블록들은 통상적인 보도블록의 단점인 무겁고 깨지기 쉬운점들을 개선시켜 줄 수 있고 우수한 반발탄성을 갖는 것이 었으나, 온도변화에 따라서 수축과 팽창이 크게 발생하였고 큰 부력을 갖는 것이어서 시공 후 많은 문제점을 갖는 것이었다.Such double sidewalk blocks can improve the heavy and fragile points which are disadvantages of conventional sidewalk blocks and have excellent rebound elasticity, but shrinkage and expansion occurred largely according to temperature change and have a large buoyancy. I had a problem.

즉, 온도가 낮은 동절기에는 블록자체가 크게 수축되는 관계로 인접하는 블록과의 틈새가 커지게 되었었고, 그 커진 틈새에 각종 이물질이나 오염물질이 박혀지게 되어서 보도블록으로 포장된 노면을 깨끗하게 유지하는데 많은 어려움이 있었다.In other words, in winter, when the temperature itself is low, the gap of the block itself is greatly contracted, and the gap between the adjacent blocks is increased, and various foreign substances or contaminants are embedded in the gap to keep the road surface paved with the sidewalk block clean. There were many difficulties.

또 온도가 높은 하절기에는 블록자체가 크게 팽창하면서 블록이 위로 치솟는 형태로 변형되어 보도의 노면이 굴곡지게 되었었다.In the summer, when the temperature is high, the block itself expands so much that the block soars upward, and the road surface is curved.

그리고 보도에 있는 배수구나 배수로의 막힘이나 집중호우등에 의해서 블록아래쪽에 물이 찰 경우 블록이 큰 부력을 받게 되므로 보도의 바닥으로 부터 블록이 들뜨게 되는 등의 문제점도 있었다.In addition, when the water fills the bottom of the block due to a blockage of a drain or drainage drainage on the sidewalk, the block receives a large buoyancy, and thus the block is lifted from the bottom of the sidewalk.

본 고안은 시멘트배합물을 주성분으로하는 콘크리트 기층위에 폐타이어고무칩이나 폐우레탄칩과 같은 탄성칩을 주성분으로 하는 탄성표층이 견고하게 결합된 이중보도블록을 제공하는데 기술적 과제를 둔 것이다.The present invention aims to provide a double sidewalk block having a firmly bonded elastic surface layer composed mainly of elastic chips such as waste tire rubber chips or waste urethane chips on a concrete substrate composed mainly of cement compounds.
