  Since the corner decorative cover 1 has the above-described configuration, when the corner decorative cover 1 is installed in the vicinity of the corner C as shown in FIGS. 1 and 7, the following procedure is used.

  First, in the cover preparation step, as shown in FIG. 7, the through hole cover piece 2 and the corner cover piece 3 have a total length L2 in the longitudinal direction according to the piping distance L1 from the first wall W1 to the through hole 13. By connecting and fixing each other so as to correspond to this piping distance L1, the total length L2 in the longitudinal direction of the through hole cover piece 2 and the corner cover piece 3 is adjusted.

  At this time, when the through-hole cover piece 2 and the corner cover piece 3 are connected to each other, as shown in FIGS. 4 to 6, a numerical value on the scale 16 corresponding to the total length L2 in the longitudinal direction at that time (for example, “230 ”,“ 260 ”, etc.). Therefore, the total length L2 in the longitudinal direction of the through hole cover piece 2 and the corner cover piece 3 can be easily known by reading the numerical value on the scale 16 indicated by the instruction means 17. Therefore, the total length L2 in the longitudinal direction of the through-hole cover piece 2 and the corner cover piece 3 can be adjusted quickly and accurately.

  Next, the process proceeds to the base mounting step, and the mounting bases 5 and 6 are screwed to predetermined positions on the first wall W1. For this purpose, a screw (not shown) is inserted into the screwing portion 53 of the mounting base 5 and screwed into the first wall W1, and each screwing portion 63 of the mounting base 6 is screwed (not shown). And is screwed into the first wall W1.

  Then, it transfers to a piping process and the piping 15 is arrange | positioned along the 1st wall W1 and the 2nd wall W2.

  Next, it transfers to a 1st cover attachment process, and the piping cover piece 4 is attached to the attachment base 6 so that a part (part along the 1st wall W1) of this piping 15 may be covered.

  Next, the process proceeds to the second cover attaching step, and the corner cover piece 3 and the through hole cover piece 2 are attached to the attachment base 5 so as to cover a part of the pipe 15 (part along the second wall W2) and the through hole 13. Attach to.

  Finally, the process proceeds to the cover fixing step, and the through hole cover piece 2 is screwed to the second wall W2. For this purpose, a screw (not shown) is inserted into the screwing portion 24 of the through-hole cover piece 2 and screwed into the second wall W2.

  Then, the corner decorative cover 1 is placed in the vicinity of the corner C so as to cover the pipe 15 and the through hole 13, and the construction of the corner decorative cover 1 is finished here.

  Thus, when the corner decorative cover 1 is constructed, the length of the corner decorative cover 1 is quickly and accurately determined according to the piping distance L1 from the first wall W1 to the through hole 13 in the cover preparation process. Can be adjusted. For this reason, the corner decorative cover 1 can be constructed with high accuracy in a short time at any construction site.

  In the second cover attaching step, since the through hole cover piece 2 is already fixed to the corner cover piece 3, the through hole cover piece 2 is attached after the corner cover piece 3 is attached to the attachment base 5. However, there is no problem that the entire length L2 in the longitudinal direction is changed with respect to the corner cover piece 3 and the through hole cover piece 2 is dropped from the corner cover piece 3. Therefore, the corner decorative cover 1 can be smoothly constructed.

  Furthermore, in the cover fixing step, the corner decorative cover 1 is fixed to the first wall W1 and the second wall W2 only at two points (screwing portion 24, screwing portion 53). However, as described above, since the corner cover piece 3 is provided with the pair of left and right lifting prevention pieces 36, as described below, the connection portion between the through hole cover piece 2 and the corner cover piece 3 is lifted. Can be prevented. As a result, a situation in which a gap is not generated in the connecting portion does not occur, and the appearance of the corner decorative cover 1 can be improved.

  That is, the through-hole cover piece 2 and the corner cover piece 3 are merely fixed to each other only when the locked portion 8 is fitted to the locking portion 7. Therefore, if the corner cover piece 3 is not provided with the anti-lifting piece 36 as shown in FIG. 8A, for example, as shown in FIG. When the pipe 15 presses the through-hole cover piece 2 and the corner cover piece 3 toward the front side (arrow D direction), the through-hole cover piece 2 is restrained from rotating slightly around the screwing portion 24. I can't. Therefore, the connection part of the through-hole cover piece 2 and the corner cover piece 3 will float to the near side.

  On the other hand, as shown in FIG. 9 (a), when the anti-lifting piece 36 is provided on the corner cover piece 3, as shown in FIG. 9 (b), piping is provided within the corner decorative cover 1. Even when 15 presses the through hole cover piece 2 and the corner cover piece 3 toward the front side (in the direction of arrow D), the lift prevention piece 36 hits the back surface of the first flange 22 of the through hole cover piece 2, thereby It is possible to restrain the cover piece 2 from rotating around the screwing portion 24. As a result, it is possible to prevent a situation where the connecting portion between the through hole cover piece 2 and the corner cover piece 3 is lifted to the near side.

  And the decorative cover 1 for corners constructed in this way, as described above, when the through-hole cover piece 2 and the corner cover piece 3 are fixed in the longest state, the locked portion 8 is the through-hole cover piece 2. The first vertical wall portion 23 is covered and hidden. Therefore, not only when the corner decorative cover 1 is in the shortest state (see FIG. 5) but also in any other state (see FIGS. 4 and 6), the locked portion 8 can be seen from the outside. Can be avoided. As a result, the appearance of the corner decorative cover 1 can be improved regardless of the length L2 of the through hole cover piece 2 and the corner cover piece 3 in the longitudinal direction.

In addition, the corner decorative cover 1 has a through hole cover piece 2 and a corner cover piece 3 connected to each other regardless of the length L2 of the through hole cover piece 2 and the corner cover piece 3 in the longitudinal direction. The pair of concave and convex left and right engaging portions 7 are not exposed to the outside. Therefore, it is possible to suppress the accumulation of indoor dust in the locking portions 7 and to keep the corner decorative cover 1 as a whole beautiful.
