PURPOSE:To ensure sufficient thermal insulation effect, while blocking longitudinal shift of thermally insulated piping positively, by a constitution wherein pressing parts are provided at two or more points movably toward the central part of the thermally insulated piping from different directions. CONSTITUTION:First engaging parts 8a, 8a are engaged with one engaging groove 2b and second engaging parts 8b, 8b are pressed into the other engaging groove 2c. A thermally insulated piping P is then mounted at a pipe supporting part on the upper face of a supporting beam 2 and an operating bolt 9 is rotated until guide protrusions 7b, 7b reach predetermined values on a scale 10. Consequently, cam parts 7a, 7a come into contact each other to move first and second pressing parts 6c, 6c and 7c toward the central part O of the thermally insulated pipe P from different directions thus fixing the pipe P in place. |
