<p>PROBLEM TO BE SOLVED: To provide a piping mounting structure, which can be easily laid, does not depend upon skill on a laying spot and has excellent space efficiency. SOLUTION: The piping mounting structure is used for the partition wall sections 22, 23 of a meter box partition 20 installed at the floor section 12 of a unit building having fire-resistive specifications and a fire-preventive block 24, into which a sleeve 18 for a water-supply hot-water supply piping or the sleeve 19 for a gas piping is inserted, is mounted in the piping mounting structure. In the fire-preventive block 24, cylindrical members 26, 27, into which the sleeve 18 for the water-supply hot-water supply piping or the sleeve 19 for the gas piping is inserted, is disposed to a fire-preventive block body 25 formed in an approximately box shape and communicating space hole sections 26a, 27a are formed, and a space in the block body is filled with concrete 28. Thermal-expansion expanded rubber sheet 30 are interposed among the sleeve 18 for the water-supply hot-water supply or the sleeve 19 for the gas piping and the interior walls of the cylindrical members 26, 27 in the communicating space hole sections 26a, 27a.</p> |
