폐폴리올레핀 폼과 탄성 포장재로 구성된 어린이 놀이터 바닥의 안전성에 관한 실험적 연구 = Study on the Safety of Playground Flooring Made of Polyolefin Foam Waste and Rubber Paving

국문 초록 (Abstract)

본 연구에서는 폐폴리올레핀 폼을 완충재로 이용한 어린이 놀이터 바닥의 안전성을 알아보기 위하여 한계하강높이, 보행적합성 및 장기피로예측, 미끄럼저항성에 대하여 시험하고 평가하였다. 시험체는 두께 30mm, 50mm, 70mm의 폐폴리올레핀 폼에 각각 탄성 포장재를 12mm, 15mm 두께로 포설한 6종류로 하였다. 한계하강높이 시험은 KS G 5758:2009에 의거하여 실시하였다. 보행적합성 및 장기피로예측 시험에는 바닥 경도 시험장치(O-Y HMA)를 이용하였으며, 미끄럼저항성 시험에는 휴대형 미끄럼 시험기(ONO PPSM)을 이용하였다. 시험결과, 폐폴리올레핀 폼과 탄성 포장재로 구성된 바닥은 충격저감성 관점에서 상당히 안전한 것으로 나타났다. 바닥의 경도는 남성에게는 보행감이나 피로 측면에서 우수한 성능을 발휘하지만, 여성에게는 구두(미들 힐)를 신고 보행하기에 적합하지 않고 오래 사용할 경우 쉽게 피로감을 느낄 수 있는 것으로 나타났다. 미끄럼저항성은 표면에 물기 등의 이물질이 있더라도 일상적인 동작에 대해서는 비교적 안전한 것으로 나타났다.

This study is purposed to verify the safety of the floor of the children's playground using polyolefin foam waste and rubber paving. The critical fall height, walking suitability, long term physical fatigue expectation and slipperiness were tested. Polyolefin foam wastes in thickness of 30mm, 50mm and 70mm were prepared with paving the rubber paving materials in 12mm and 15mm thickness respectively. The test on the critical fall height was carried out according to KS G 5758:2009. The floor hardness test equipment (O-Y HMA) was used for the test on hardness of the floor from a viewpoint of walking suitability and fatigue. A portable slipperiness tester (ONO PPSM) was used for slipperiness test. It was revealed from the test that the floor made of the polyolefin foam waste and rubber paving were considerably safe from a viewpoint of impact absorption. With regards to the hardness of the floor, it was shown the excellent performance in the aspects of walking and fatigue for male. But it was not suitable with walking on the shoes(middle heels) for female. And they will be very fatigue if they were in a long time walking or standing. As far as the slipperiness is concerned, it was shown that it was comparatively safe for the ordinary motions even though the surface was wet.
