The purpose of this study presents useful data on the choice or development of floor covering from slip viewpoint by examining closely the impact of the changes in sliding experiments due to the wear of floor covering by walk. The result of wear practical test per ten thousand walks enforces some kind of popular floor covering and measure of coefficient of slip resistance as follows: (1) When surface of floor covering is in the state of wet, the degree of wear doesn't affect greatly in slip. (2) When surface of floor covering is in dry and clean state, most floor coverings have the tendency to lower the coefficient of slip resistance with the amount of walk on it. (3) Change in the tendency of slip resistance by wear appeared mainly due to the differences in the state of floor covering and organic floor covering appeared to have great reduction of coefficient of slip resistance than the inorganic ones. (4) According to the result of investigation on changes in tendency of coefficient of slip resistance due to the increase in the number of walk and if two hundred thousand walks were done, regardless of surface shape or kind of site, etc, the safety of floor covering, in slip viewpoint, greatly reduces.

The purpose of this study is to evaluate efficiency by the Life Cycle Cost(LCC) analysis of floor covering materials for remodeling. This study has been performed as a case study. The LCC analysis is a technique which takes account into both initial-future costs and benefits of an investment over some period of time. LCC is important in commercial decision making because it provides improved assessment of the living-term cost effectiveness of construction projects as well as alternative economic methods that focus on initial costs. For LCC analysis and comparison, the present value technique is used. The results of this study are summarized as follows; (1) A LCC analysis model of floor covering materials is suggested through a case study (2) As a result of LCC case study, the type of sheet is analysed more economical than that of tile in floor covering materials.

최근 바닥충격음 사후 성능검사 제도의 시행에 따라 공동주택 바닥 슬래브 상부에 설치되는 바닥 마감재에 대한 바닥충격음 성능 개선의 요구사항은 증가하고 있다. 하지만 현재의 KS F ISO 717-2 및 KS F 2863에서의 바닥 마감재 성능 평가방법은 완충층이 설치되지 않은 조건에서 저감량을 측정하는 것으로 되어 있다. 준공 전 성능측정 의무화로 인해 본인이 거주하는 공동주택 바닥충격음 성능의 확인이 가능한 상황에서 입주민이 거주하는 공동주택의 특성을 반영하는 온돌층이 설치된 구조에서의 성능평가는 마감재의 바닥충격음 성능에서 더 필요한 부분일 것이다. 따라서 본 논문에서는 바닥슬래브 상부 마감구조의 저감량 평가를 위해서 완충층 조건을 포함한 저감성능 평가를 제안하고, 완충층 성능에 따른 저감량의 차이를 확인할 수 있도록 마감재가 설치되지 않은 상태의 바닥충격음 성능을 동시에 표시하는 것을 제안한다.

Floor finishing materials such as floor coverings and floor mats can reduce floor impact noise easily. When an impact was applied to the floor, its finishing material is deformed and the impact force that was applied to the concrete slab is changed. The softer finishing materials were, the more impact force decreased. An experimental study was performed using 14 PVC floor coverings and 16 floor mats to capture the characteristics of impact force and impact noise in the residential buildings. The test results show that the impact force spectrum and the floor impact noise spectrum have a linear relationship in the case of a bare concrete slab, and the characteristics of impact force reduction are the same as those of floor impact noise reduction.

현대사회는 대도시의 구조물 설계 시 협소한 공간제약을 극복하기 위해 옥상 및 지하공간을 활용하고 있으며, 이에 따라 바닥재의 시공도 증가하고 있다. 바닥재의 미끄럼저항성능은 보행자 및 운전자의 안전성 및 쾌적성 관점에서 대단히 중요한 성능임에도 불구하고, 바닥재의 미끄럼저항성능에 대한 뚜렷한 기준이 없어 개선이 되고 있지 않은 실정이다. 본 논문에서는 국토해양부의 도로안전시설 설치 및 관리지침과 서울시의 서울형 보도포장 미끄럼 저항 기준에 기초하여 미끄럼저항성능의 평가방안을 제시하였다. 세 가지의 우레탄 바닥재 시공법을 선정하여 실험적인 연구를 통해 각 바닥재의 미끄럼저항성능을 분석하고, 제시된 평가 방안에 따라 평가하였으며, VE분석을 통해 세 가지 바닥재 시공법의 성능을 종합적으로 평가함으로써 미끄럼저항성능이 우수한 바닥재가 시공될 수 있도록 독려하였다. 본 논문에서 제시된 평가방법에 따른 VE분석 결과, 미끄럼저항성능이 최대 4배 이상 향상되었던 파티클재료를 첨가한 공법이 83.86의 성능지수를 보임으로써 기타 비교안에 비해 가장 우수한 성능을 나타내었다.

Five floor coverings were tested with three different types of floor structures in the standard test building in order to evaluate the effectiveness of the floor impact sound reduction. The level of floor impact sound reduction is influenced by not only the types of floor coverings but interrelationship between the floor coverings and floor structures. From the tests, it was found that floor coverings were effective in reducing the floor impact sound using the light impact source. In addition, proper mixtures of the floor structure and the floor covering have shown effectiveness to a certain extent in reducing the floor impact sound using the heavy impact source.

Floor coverings and Mats are for children are economical and has excellent workability, as well as they can reduce floor impact noise effective. "When these floorings contact to impact source, they are deformed and change impact force characteristics that strikes floor structure. It is important to measure the impact force spectrum of floorings in order to evaluate reduction of floor impact noise for floorings. In experimental test of floor impact noise and impact force for 14 PVC vinyl floor coverings and 16 mats for children, we confirmed that the impact force spectrum directly related to the floor impact noise spectrum.

Floor impact sound level is affected by various factors. This study was examined about impact sources and floor coverings influenced at floor impact sound. So this study wishes to get method to reduce sound pressure level of receiving room. Light-weight impact sound in mid frequency and Heavy-weight impact sound in low frequency was affected by floor coverings. Therefore, method to reduce floor impact sound level is to use proper floor coverings. Some coverings can amplify the heavy-weight impact sound in low frequency. Floor impact sound sources used measurement and analysis were standard heavy-impact source(Tapping, Bang, Ball) and living impact sources(Cleaner, Chair, Toy-car, Soccer ball). And Floor coverings used measurements were various thickness vinyl, laminate(or ply-wood) floor. Especially vinyl floor coverings were very effective method to reduce floor impact.

Impact sounds, such as those created by footsteps, the dropping of an object or the moving of furniture, can be a source of great annoyance in residential buildings. The character and level of impact noise generated depends on the object striking the floor, on the basic structure of the floor, and on the floor covering. This study base on the evaluate of isolation performance of impact sound according to the impact noise reduction methods. Reduction methods consist of four ways. First way is increase thickness of bare floor and other ways are using the soft coverings on the floor and ceiling assembles. Last way is make floating floor with shock absorbing materials.
