碩士 === 國立臺灣科技大學 === 建築系 === 105 === In order to meet various types of space demands, the interior partitions of a building is relatively complex. A fire zone is usually used to avoid the spread of fire when it occurs. There are certain regulations and limitation of fire resistance period for the pipes passing through fire zone while there are no relevant regulations for single piping passing through in other spaces. In this study, different tunneling methods are applied to two-inch PVC pipes passing through structure to analyze whether there is any potential factor existed in the structure that is passed through by the pipe as well as find out whether the fire resistance is in accordance with CNS15814-1. The study used four different types of structure, tunneling method A, B, C and D, to run an-hour fire resistance test. A 30cm steel pipe was added on the exposed sides of the PVC pipes for method A, B, C and different lengths of 50cm, 10cm, and 20cm steel pipes were added on the unexposed side respectively while no steel pipe added for method D. They were applied to two different situations – PVC pipe ends are with ceramic cotton stuffing or non-stuffing. Method A, B and D were tested with the PVC pipe ends stuffing and method A, B, C and D were tested without PVC pipe ends stuffed. The experimental results were analyzed and compared to find the best method. Method A and B could pass the test when the PVC pipe ends were stuffed, however, only Method C could pass the test with no PVC pipe end stuffing. Method D, whether its pipe end is stuffed or not, couldn’t pass the test since it exceeded the standard at 37 minutes and 39 minutes respectively in the test.; Method A and B, under the circumstance of no stuffing at the pipe ends, exceeded the standard at 45 minutes and 49 minutes respectively. Therefore, it can be judged that method C is the best structure of tunneling.
