그리고, 본 발명은 내구성, 내충격성이 우수할 뿐만 아니라 탈색 변형이 되지 않도록 하는 난간대 부품의 합성조성물 및 이를 이용한 난간대 부품의 제조방법에 관한 것이다.The present invention also relates to a synthetic composition for a railroad band component which is excellent in durability and impact resistance as well as preventing discoloration and deformation, and a method for manufacturing a railroad band component using the same.
일반적으로 도로, 교량, 계단 등에 보행을 안전하게 유지하기 위한 안전장치 즉, 난간구조물을 설치하고 있다.Generally, safety devices such as roads, bridges, and stairs are installed to secure walking.
이와 같이 시설되는 난간구조물의 상세한 구조를 보면, 상기 난간레일은 난간포스트를 관통하여 고정되거나, 또는 난간포스트에 난간레일이 용접 고정되는 2가지의 방법으로 조립되고 있다.In view of the detailed structure of the railway structure thus constructed, the railway rail is fixed by passing through the railway post, or is assembled by two methods in which the railway rail is welded and fixed to the railway post.
그러나, 상기한 종래의 난간레일 조립 구조 및 방법은 현장에서 정교한 구멍을 뚫기 어렵고 미관이 험상굳은 형상을 갖고 있어 신품같은 느낌이 들지 않으며, 정확한 조립이 어려우며, 또한 용접을 하기 위하여 용접공과 용접기, 절단기, 전력인입 등이 어렵고 용접부위가 변색되어 후공정으로 미려하게 하기 위해서는 공사기간이 연장되고 및 인력과 비용이 추가는 단점이 있었다.However, the above-mentioned conventional rail railing assembly structure and method are difficult to pierce holes in the field and have an aesthetic shape so that they do not feel like new products, and it is difficult to accurately assemble them. Also, , Power input is difficult, and the welding part is discolored, so that the construction period is lengthened and workforce and cost are added in order to make it more beautiful in the post-processing.
또한, 보행자의 안전을 위해 설치되는 난간대의 경계면에는 자동차, 오토바이, 건설현장 등에 따른 소음 등이 발생하여 소음으로 인한 스트레스를 항시 받고 있어 평정심을 잃는 문제점이 대두되고 있는 실정이다.In addition, there is a problem of losing consciousness because the noise caused by the automobile, the motorcycle, and the construction site occurs at the boundary of the railroad guardrail installed for the safety of the pedestrian, and the stress due to the noise is always received.
상기 문제점을 해결하기 위해, 2010년 12월 22일자 출원번호 제10-2010-0132083호(발명의 명칭 : 블록형 합성목재 난간대)로 출원된바 있으며, 청구범위는 " 인도 및 도로의 경계, 계단 등에 안전과 경계를 위해 설치되는 합성목재 난간에 있어서, "ㅛ" 형상으로서 수직부는 제 1지주와 제 2지주가 있고 하부는 스커트와 평판이 층상으로 형성되어 바닥면과 결착되는 지주대와; 난간의 가로방향 상부와 하부에 가로대가 형성되고, 상기 가로대의 양단에 삽입되어 좌우/상하로 가변되는 제 1회동수단과, 상기 가로대의 상부와 하부 사이에 일정간격으로 다수개의 난간살이 형성되고, 상기 난간살의 양단부에 삽입되어 좌우로 가변되는 제 2회동수단과, 상기 난간살 사이에 소음방지를 위한 방음판이 설치되고, 상기 가로대의 양단에 결합된 제 1회동수단을 좌우의 제 2지주와 제 1지주에 삽입 결착하기 위한 세로대가 형성된 합성목재 난간블록과; 좌우의 제 1지주와 제 2지주에 합성목재 난간블록을 안착하고 좌우측 세로대 상부를 결합하기 위한 포스트 캡;을 결합하는 것을 특징으로 하는 블록형 합성목재 난간대. " 이다.In order to solve the above problems, the invention was filed with the application No. 10-2010-0132083 of December 22, 2010 (the name of the invention: block type synthetic wooden balustrade) And the lower part of which is formed in a layered structure with a skirt and a flat plate so as to be engaged with the floor surface, A first rotating means having a cross bar at the upper and lower sides in the transverse direction and being inserted into both ends of the cross bar to be changed in the left / right / up and down directions, and a plurality of balusters formed at regular intervals between the upper and lower portions of the cross bar, A second rotating means inserted into both end portions of the barrel and being variable in the left and right direction and a soundproof plate for preventing noise between the barrel and the first and second rotating means, And a post cap for seating a synthetic wood rail block on the first and second pillars on the left and right sides and for joining the upper and left legs on the first and second pillars, It is a block-type synthetic wooden balustrade featuring. "
그러나, 상기 종래의 블록형 합성목재 난간대는 지주, 브라켓, 포스트 캡, 스커트 등이 합성목재로 제조되는바, 합성목재로 제조되는 지주, 브라켓, 포스트 캡, 스커트 즉, 난간대 부품이 오랜 시간 경과시, 햇빛, 강우, 강설 그리고 외부의 충격에 잘 파손되는 문제점이 있었다.However, the conventional block type synthetic wood railings are made of synthetic wood such as pillars, brackets, post caps, skirts and the like, and the synthetic pillars, brackets, post caps, skirts, , Sunlight, rainfall, snowfall, and external impact.
이로 인해, 난간대 부품의 교체 비용이 증가하는 문제점이 있었다.As a result, there is a problem that the replacement cost of the railing part is increased.
