PURPOSE:To provide the bearing structure of a level adjusting bolt capable of positively positioning a waterproof pan. CONSTITUTION:A level adjusting section L is constituted onto the underside of a waterproof pan 10, level adjusting bolts 1, 1... are placed onto a concrete bottom 13 through bearing plates 3, 3..., and the adjusting bolts 1, 1... are turned, thus adjusting the height of the waterproof pan 10. The undersides of boss sections 1a are received by the pan sections 2a of nuts 2 with washers by screwing the bolts 1 for adjusting a level into said nuts 2 with the washers, thus increasing the strength of bearing sections while receiving load applied to the level adjusting bolts 1 in the horizontal direction by the side faces of nuts 2b. Accordingly, the bolts 1 for adjusting the level are born positively, and displacement, etc., are prevented, thus positioning the waterproof pan 10, then improving the accuracy of execution. |
