<p><P>PROBLEM TO BE SOLVED: To enlarge a construction space by eliminating the need of a device for directly supporting bending parts on the ground without spoiling a function for preventing the bending parts and straight parts from falling. <P>SOLUTION: The support system includes a pipe P, leaded from the ground into the building, having an end 1 side fixed to the ground, another end 2 side fixed to the building and at least one bending part 3 bent in an approximate L-shape formed down the pipe P, ball joints B provided at least three positions including a neighbourhood of at least one bending part 3 of the pipe P, a neighbourhood of the ground at the end 1 side of the pipe P and a neighbourhood of the building at the end 2 side of the pipe P and a supporting device 50 for supporting at least either one of two straight parts 5 of the pipe P which is fixed to the ground and is to the bending part 3 in a manner allowing movement in vertical and horizontal directions. A rotation limiting mechanism 20 for limiting rotation of the ball joints B provided in the neighbourhood of the bending part 3 to only a horizontal plane direction and a rotation restrain mechanism 90 for restraining rotation of the pipe supported by the supporting device 50 around its axis are provided for the support system. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
