PIPE INNER-LAYER STRUCTURE AND CONNECTION MEMBER USED THEREIN

摘要

To provide a pipe inner-layer structure that allows inner surface materials to be accurately disposed, includes inner surface materials, simplifies installation work by saving labor in assembling component members, and has durability over a long period of time even after the completion of work, the pipe inner-layer structure of a pipe includes: fixed members 2 that are installed along an inner peripheral surface of a pre-installed pipe 1 at intervals in the pipe-axial direction of the pre-installed pipe 1; connection members 3 that are disposed on the fixed members 2 and include first fitting portions 31 to which an inner surface material 4 is fitted and second fitting portions 32 for installation to the fixed member 2; and the inner surface material 4 in the shape of a band, which is fitted to the first fitting portions 31 of the connection members 3 and is provided across fixed members 2 adjacent to each other in the pipe-axial direction. The connection members 3 are adapted so as to be divided and disposed on the fixed members 2 through the second fitting portions 32 included in the respective connection members 3.
