The present invention relates to a fire sealing structure of a wall penetration unit for preventing the movement of a pipe caused by ship vibration by using minimum costs and materials since a hollow pipe sleeve is formed on a wall, the pipe sleeve is penetrated by a pipe, a space between the pipe and the pipe sleeve is filled with filler sleeves having thermal expansion property, inner end parts are formed on both sides of the pipe by forming the filler sleeve shorter than the pipe sleeve, and sealing units are respectively formed on inner end parts and filled with a sealant. The present invention adheres to the pipe and the pipe sleeve firmly by thermal expansion property in case of fire so as to increase waterproof and flameproof properties and is safe against a fire or a flooding accident. |
