<p><P>PROBLEM TO BE SOLVED: To provide a method for forming a draining portion of a staircase, which enables the draining portion to be easily formed by suppressing an increase in cost to the minimum even in the case of the staircase uncovered with a covering material or the staircase covered with an existing covering material, and to provide a draining structure of the staircase constructed by the method. <P>SOLUTION: In this method for forming the draining portion of the staircase, an unsolidified material 20 for forming the draining portion is laterally and linearly bonded to a riser surface 1a of the staircase 1, formed in a desired draining cross-sectional shape protruding forward by means of a shaping mold material 3, and solidified while keeping the draining cross-sectional shape almost as-is. Thus, the laterally and linearly elongated draining portion 2 is easily formed on the riser surface 1a of the staircase 1 while suppressing the increase of the cost to the minimum. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
