Foundational Experiments about Bending Strength of Floating Floor Method on Roof-top by using a Polyurethane Board

우레탄 보드를 활용한 옥상 뜬바닥 구조공법의 휨강도에 관한 기초적 실험

The roof-top of deteriorated building is necessary to improve that performance of waterproof and heat insulation is lowered. However, the existing method is difficult to supply due to complicated process and high cost. Therefore, practical condition and demand for occupant considered, it is necessary to develop inexpensive and easy method, such as a floating floor method using thermal insulation. This study is experiments on foundational experiment was conducted on the bending strength. A polyurethane board for experiment forms a square and it has various size that 25cm, 33cm, 50cm, and 100cm. Meanwhile, the uniform load of 200kg/㎡ which general working load is applied to the bending strength.
