A method of constructing the baseboards 3, 3 at the inside corner 4 using the baseboard inside corner material 10 will be described with particular reference to FIG.

First, as shown in FIG. 5(a), after aligning the rear side corner portion of the contact piece 31 of the base material 30 with the inside corner 4 between the wall surface 1 and the floor surface 2, As shown in 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. As shown in FIG. By fixing the baseboards 3, 3, the abutment piece 31 of the base member 30 is fixed in a state sandwiched between the wall surface 1 and the baseboards 3, 3, so that the base member 30 can be fixed with an adhesive or a nail. does not need to be fixed with

Next, as shown in FIG. 5(c), when the surface material 20 is brought closer to the inner corner 4 from the front of the interior side of the baseboards 3, 3 fixed to the wall surface 1 (see also FIG. 4(a)). , the fitting portion 23 of the surface material 20 begins to fit with the fitting portion 32 of the base material 30 . Furthermore, the covering piece 21 of the surface material 20 is pressed against the end surfaces 3b, 3b of the baseboards 3, 3, and while the upper end covering surface 22c is substantially in contact with the end upper surfaces of the baseboards 3, 3, the back side thereof is The baseboard mounting structure shown in FIGS. is obtained.

In this attached state, the surfaces 3b, 3b of the ends 3a, 3a of the baseboards 3, 3 on the inside corner 4 side are covered with the covering pieces 21 of the surface material 20, and the baseboard ends 3a, 3a Since the upper surface is covered with the upper end portion 22 of the surface material 20, the gap 5 is not exposed.

The engagement between the engaging protrusions 23c and 32a is strong enough to maintain the engaged state between the fitting portions 23 and 32, but the surface material 20 can be released relatively easily by pulling strongly. Therefore, there is no problem in performing the above work. In addition, since the base material 30 is only arranged in a state sandwiched between the baseboards 3, 3 and the wall surface 1, the base material left in the inside corner 4 after the baseboards 3, 3 are removed. 30 can be easily removed. Furthermore, since neither the surface material 20 nor the base material 30 is damaged by nailing or the like, they can be reused for the baseboards 3, 3 of the same shape and size.
