A plurality of bolt legs 2, 2, 2 are suspended from the bottom side of the waterproof pan 1, and a pipe P or the like is installed at a renovation site where the waterproof pan 1 is installed. If the obstacle is present, it is necessary to move the position of the bolt leg 2 at the site. In order to move the position of the bolt leg 2, the perspective view of FIG. 3 and the longitudinal sectional configuration diagram of FIG. 5 is used, and the metal fitting 3 having the structure shown in the bottom view of FIG. 6 and the right side view of FIG. 7 is used.

  The metal fitting 3 is formed by bending a steel plate, and has a horizontal attachment surface 4 set to a length capable of straddling between the pair of ribs 1c, 1c of the waterproof pan, and the length of the attachment surface 4 Left and right rib fixing surfaces 5 and 5 bent slightly outward in the vertical direction from both ends in the direction, vertical side surfaces 6a and 6b bent substantially vertically from the edge of the width direction of the mounting surface 4, and one side vertical The penetration preventing plate 7 is bent at the lower end of the side surface 6a in parallel with the mounting surface 4.

A through hole 4a is formed in the mounting surface 4 so as to penetrate vertically, and a nut 8 of, for example, M16 is fixed on the through hole 4a by welding. In addition, two screw holes 5a are formed in the rib fixing surfaces 5 and 5 that are suspended from the left and right ends in the longitudinal direction, and each of the screw holes 5a and 5a is formed of a long hole that is long in the vertical direction. ing.
A gap S is formed between the inner sides of the rib fixing surfaces 5 and 5 on the left and right sides in the longitudinal direction and both longitudinal ends of the vertical side surfaces 6a and 6b. The gap S is integrally formed on the back surface of the waterproof pan. The ribs 1c and 1c that are present can be fitted.

  In addition, ribs 1c and 1c are integrally formed in a grid pattern on the back side of the washing scene 1a of the waterproof pan 1 and the bathtub mounting surface 1b. As shown in FIG. The mounting surface 4 of the metal fitting 3 is straddled between the pair of ribs 1c, 1c at this location, and the left and right rib fixing surfaces 5, 5 on both ends in the longitudinal direction are fitted in contact with the outside of the pair of ribs 1c, 1c. Can be included.

In addition, since each rib 1c is formed in an inclined shape so that the diameter of the tip side is reduced, the rib fixing surfaces 5 and 5 on both the left and right sides are mounting surfaces so that the rib 1c can be in close contact with the outside of the rib 1c. It is bent slightly inclined from 4 to the outside.
A cushioning material is adhered to the inside of the left and right rib fixing surfaces 5 and 5, that is, the gap S side. Further, the buffer material 9 is also attached to the outside of the vertical side surfaces 6a and 6b.
