<p>PURPOSE: To provide a fire resistant jig that can improve fire resistance and constructing performance, and the fire resistant structure of a pipe through part using this fire resistant jig. CONSTITUTION: A fire resistant jig 50 is mounted on pipelines 10A, 10B covered with heat insulating material. This fire resistant jig 50 is provided at the pipe through part 101 of a partition wall 100. The fire resistant jig 50 has cylindrical bodies 20, 30 formed of fire resistant material and removable from the positions, corresponding to both ends in the pipe through parts 101, of the pipelines 10A, 10B. The cylindrical bodies 20, 30 are formed of upper shells 21, 31 and lower shells 22, 32 opened/closed so as to be detachable from the pipelines 10A, 10B or clamp them. Both cylindrical bodies 20, 30 are connected to each other by a pin 23 formed of a solder bar or the like, and incombustible material (or fire resistant material) such as mortar is filled in the pipe through part 101.</p> |
