<p><P>PROBLEM TO BE SOLVED: To provide a pipe connection structure, capable of reliably connecting pipe portions to each other one of which is covered with a fireproof/soundproof cover formed extending from the pipe end and the other of which is covered with a fireproof/soundproof cover, formed retracting from the pipe end. <P>SOLUTION: The fireproof/soundproof cover 3 with which one pipe portion A is covered is formed, extending by a predetermined length outward from the pipe end in the direction of a pipe axial center, and the fireproof/soundproof cover 4 with which the other pipe portion is covered is formed, retracting a predetermined length inward from the pipe end in the direction of the pipe axial center. In an extension cylinder portion 3C of one fireproof/soundproof cover, a cut 5 is formed, through which the end of at least one pipe portion can be viewed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
