Engagement projections 23c and 32a that can engage with each other are formed on the inner surface of the opposing projecting pieces 23a and 23a of the engagement portion 23 and the outer surface of the engagement portion 32, and the surface material 20 and the base material 30 ( More specifically, while providing an arbitrary space L1 (FIG. 4B) between the covering piece 21 of the surface material 20 and the abutting piece 31 of the base material 30, these are connected to each other by the fitting portions 23 and 32. Integration can be achieved through fitting, and that state can be maintained. In addition, the engagement state between the engagement protrusions 23c and 32a can be relatively easily released by applying a force in a direction in which the surface material 20 is separated from the base material 30. Is detachable.

The method of applying the baseboards 3 and 3 at the corner 4 using the corner material 10 for cornering the baseboard will be described in particular with reference to FIG.

First, as shown in FIG. 5 (a), after the back side corner of the contact piece 31 of the base member 30 is aligned with the entry corner 4 between the wall surface 1 and the floor surface 2, As shown in FIG. 5 (b), the baseboards 3, 3 are fixed to the wall surface 1 with screws (not shown) while pressing the baseboards 3, 3 against the contact pieces 31 of the base member 30. When the baseboards 3 and 3 are fixed, the abutment pieces 31 of the base member 30 are fixed in a state of being sandwiched between the wall surface 1 and the baseboards 3 and 3. There is no need to fix using.

Next, as shown in FIG. 5 (c), when the surface material 20 is approached from the indoor side front of the baseboards 3, 3 fixed to the wall surface 1 toward the inset corner 4 (see also FIG. 4 (a)). Then, the fitting portion 23 of the surface material 20 starts fitting with the fitting portion 32 of the base material 30. Further, the covering piece 21 of the surface material 20 is pressed against the end surfaces 3b, 3b of the baseboards 3, 3 so that the upper end covering surface 22c is substantially in contact with the upper surfaces of the ends of the baseboards 3, 3, while the back side thereof is The surface material 23 is advanced so as to press the corners of the edges 22c, 22c against the inset corners 4 and is fitted deeply with the base material 30, so that the baseboard mounting structure shown in FIGS. 4 (b) and 4 (c) is obtained. Is obtained.

In this mounting state, the surfaces 3b, 3b of the ends 3a, 3a on the corners 4 side of the baseboards 3, 3 are covered with the covering pieces 21 of the surface material 20, and the baseboard ends 3a, 3a Since the upper surface is covered by the upper end portion 22 of the surface material 20, the gap 5 is not exposed. Also, in this mounted state, the covering piece 21 of the surface material 20 is substantially in contact with the end surfaces 3b, 3b of the baseboards 3, 3, so that the covering piece 21 of the surface material 20 and the contact piece of the base material 30 31 is substantially the same as the thickness T1 of the baseboards 3 and 3.

When the baseboards 30 are fixed to the wall surfaces 1 (FIG. 5C), the baseboards 30 are pressed against these baseboards 3 and 3 and are sandwiched between the baseboards 3 and 3. It is held in a fixed position. Therefore, there is no need to fix the base member 30 to the wall surface 1 using an adhesive or a nail. Furthermore, when connecting the surface material 20 to the existing base material 30, it is only necessary to push the surface material 20 toward the corner. Therefore, a series of construction work can be easily performed without requiring much labor and time. On the other hand, the surface material 20 is firmly attached to the base material 30 through the fitting between the fitting portions 23 and 32 and the engagement between the engagement protrusions 23c and 32a, while the work is easy as described above. Since the surface member 20 is connected and the mounting position of the surface member 20 with respect to the base member 30 is maintained unchanged, the surface member 20 is not accidentally dropped or loosened from the mounting state shown in FIG.

When it is necessary to remove the baseboards 3 and 3 for renovation and maintenance after the cornerboard 10 for the baseboard entry corner has been installed in the entry corner 4 together with the baseboards 3 and 3 as shown in FIG. After the surface member 20 is pulled toward the user and detached from the base member 30, the baseboards 3 and 3 may be removed. The engagement between the engagement projections 23c and 32a is strong enough to maintain the engagement between the engagement portions 23 and 32, but can be relatively easily released by strongly pulling the surface material 20. Therefore, there is no problem in performing the above operation. Further, since the base member 30 is merely disposed in a state sandwiched between the baseboards 3 and 3 and the wall surface 1, after removing the baseboards 3 and 3, the base member 30 left in the corner 4 30 can be easily removed. Further, since neither the surface member 20 nor the base member 30 is damaged by nailing or the like, the surface member 20 and the base member 30 can be reused for the baseboards 3 and 3 having the same shape and size.
