The upper skirting board 4 is a long material having a rectangular cross section made of wood. On the lower surface of the upper skirting board 4, a fitting groove 21 is formed obliquely upward, and the back surface 22 (the wall W side) of the upper skirting board 4 is formed in a slightly tapered (θ) shape. This is because the top surface portion 23 of the upper skirting board 4 is easily brought into close contact with the wall W when the upper skirting board 4 is attached. In addition, a cosmetic material 25 is provided on the top surface portion 23 and the front surface portion 24 (indoor side) of the upper baseboard 4.
Is affixed.

As shown in FIGS. 3 (a) and 3 (b), the baseboard mounting device 1 has a plate-like substrate portion 11 and locking projections from two upper and lower portions on the lower surface of the substrate portion 11, respectively. 12,1
3 are protrudingly provided, and locking pieces 12a, 13a are formed on the front ends of the locking projections 12, 13, respectively, on opposite sides.

Further, a locking plate portion 14 projecting obliquely upward (opposite the wall W) is formed on the upper portion of the substrate portion 11, and is formed on the back surface (the wall W side) of the locking plate 14. Are provided with locking concave and convex portions 15 to prevent attachment and detachment after locking. The direction of the locking plate 14 is preferably obliquely upward, but is not limited to this. Screw holes 16 are formed in the upper and lower sides of the locking projection 12 in the substrate portion 11, respectively.
Is provided.

As shown in FIG. 2, the lower skirting board 5 is composed of a long wooden board-shaped lower width lumber 6 and a mounting member 7 fixed to the back side of the lower width lumber 6. The lower width wood 6 includes a plate-like portion 28 and a bent portion 2 formed on an upper portion of the plate-like portion 28.

Are formed vertically. Further, a decorative material 25 is attached to a front portion of the plate-shaped portion 28.

The attachment 7 is a long one manufactured by extrusion of aluminum. This attachment 7
The locking projections 18 and 19 project from two upper and lower portions of the substrate 17 and the rear surface of the substrate 17, respectively, and the tips of the locking projections 18 and 19 are opposite to the facing sides. Locking pieces 18a and 19a are formed on the side.

The back surface of the lower lumber 6 is fixed to the substrate 17 of the mounting body 7 using an adhesive, and the upper end of the lower lug 6 is engaged with the locking groove 29 of the lower lumber 6. Have been. In this way, the lower skirting board 5 is formed by integrating the lower skirting wood 6 and the mounting body 7.

In the construction of a floor structure, usually, after a wall W is constructed, a floor material F is constructed with a gap P provided in the wall W. The baseboard mounting fixture 1 is fixed to the wall W, and is installed at a plurality of locations at predetermined intervals in the horizontal direction.
At this time, using the screw holes 16 of the substrate portion 11, the fixing is performed using a fastener such as a screw, or an adhesive is applied to the back surface of the substrate portion 11 and fixed to the wall body W. After temporarily fixing with an adhesive or double-sided tape, it may be fixed using a fastener.

The locking projections 12 and 13 of the baseboard attachment 1 are
The protrusion sizes of the locking protrusions 12 and 13 are set sufficiently high so that the lower skirting board 5 is arranged at a sufficient distance from the wall W. The reason why such a sufficient space is provided is to widen the gap of the air flow passage between the lower skirting board 5 and the wall W to secure a sufficient flow passage for the impact sound of the floor.

As shown in FIG. 2, the lower skirting board 5 is attached by being locked to the skirting board mounting tool 1. At this time, the mounting body 7
Pieces 18a, 1 of locking projections 18, 19 projecting from
9a are respectively connected to the locking projections 12, 13 of the baseboard mounting device 1.
Are locked to the locking pieces 12a and 13a. The upper end of the lower skirting board 5 is connected to the upper screw hole 16 of the board portion 11 of the skirting board fixture 1.
The head of the screw is difficult to see from the gap D between the upper skirting board 4 and the upper skirting board 4 because the structure is located above the upper skirting board 4.

Next, the upper skirting board 4 is mounted on the skirting board mounting tool 1. At this time, the fitting groove 21 of the upper skirting board 4 is fitted and inserted into the locking plate 14 provided on the upper part of the skirting board mounting tool 1. In this case, an adhesive may be applied in advance to the wall body W side of the upper skirting board 4 or a double-sided adhesive tape or the like may be used. With this adhesive or the like, the upper skirting board 4 is directly fixed to the wall body W in addition to being locked by the skirting board fixture 1, and the adhesion is improved.

In the baseboard mounting device 1, since the locking plate portion 14 is formed obliquely upward, the fitting groove portion 21 of the upper baseboard 4 is formed on the locking plate portion 14.
The upper skirting board 4 gradually moves in the wall W direction according to the insertion. Therefore, the upper skirting board 4 does not rub the surface of the wall W up and down, and the upper skirting board 4 does not damage the surface of the cloth material 39. Also gradually put the upper skirting board 4 on the wall W
, The insertion is easy, and the upper baseboard 4 can be arranged without a gap between the upper skirting board 4 and the wall body W.

It is important to install the upper and lower skirting boards 4 and 5 that an upper surface of the lower skirting board 5 and a lower surface of the upper skirting board 4 are required to connect the underfloor space and the indoor space. The gap is appropriately set so that a gap D (for example, about 5 mm) for floor impact sound circulation can be sufficiently secured.

Since the installation of the upper and lower skirting boards 4 and 5 including the skirting board mounting fixture 1 is a structure that is performed separately from the construction of the floor material F and the wall body W, the construction of the floor material F and the wall body W It does not matter which of the above constructions is performed first. In addition, before attaching the cross member 39, the baseboard mounting fixture 1 and the lower baseboard 5 are constructed,
Thereafter, the cross member 39 is attached to the middle of the lower skirting board 5 and then the upper skirting board 4 is attached.
Can be closed at the bottom. Even when the cloth material 39 is to be replaced, the skirting board attachment 1 is fixed with screws or an adhesive, and the upper and lower skirting boards 4 and 5 are also locked with an engagement fitting or an adhesive. Since these members are attached, such members can be detached without damaging the floor material F and the wall body W, and the construction is easy.

The dimension (A) from the position of the upper skirting board 4 in contact with the wall W to the outer end of the upper surface of the upper skirting board 4 is defined as follows: Dimensions to end (B)
Or more (A> B), so that the gap D is hidden from view. The gap D between the upper skirting board 4 and the lower skirting board 5 is maintained at a constant width and accurately by the skirting board attachment 1. In addition, since the gap D is formed at a position above the plate-like portion 28 of the lower skirting board 5 rising from the floor, clogging of dust and the like at the time of cleaning can be prevented.
In addition, the gap D formed in a straight line between both side surfaces of the upper and lower skirting boards 4 and 5 also serves as an accent of the upper and lower skirting boards 4 and 5 and has good design.

FIG. 4 shows a skirting board fitting 41 according to another embodiment. The skirting board attachment 41 is different from the skirting board attachment 1 according to the above embodiment in that the locking plate portion 44 is formed laterally on the indoor side, and the other is the same. In accordance with this, the upper skirting board 46 is formed with a laterally fitting groove 48 at a position slightly above the lower end of the back surface. The lower skirting board 49 has the same shape as the lower skirting board 5. A locking uneven portion 45 is provided on the upper surface of the locking plate portion 44 to prevent detachment after locking. Since the skirting board mounting tool 41 of this embodiment fits and locks the upper skirting board 46 in the lateral direction, the adhesion between the wall body W and the upper skirting board 46 is good.

Therefore, the skirting board according to the above embodiment is divided into three configurations of an upper skirting board, a lower skirting board, and a skirting board fixture, and has a simple connection structure. The gap between the upper and lower skirting boards can be maintained at a constant interval. By providing a gap D between the upper skirting board 4 and the lower skirting board 5 and using the gap as an air flow passage S, floor impact noise is emitted to the wide indoor side through the gap D. Thus, an effect of attenuating the floor impact sound in the underfloor space can be obtained.

Furthermore, the structure is such that dirt and dust are unlikely to adhere to the gap portion D. In order to fix the upper skirting board 4 and the lower skirting board 5 to the wall W, the upper skirting board 4 and the lower skirting board 5 are used. Since it is not a structure that is fixed from the surface side using a fastener such as a nail, the head of the nail or the like is not visible, and the appearance is aesthetically neat. Also,
Even if one of the interior construction and floor construction is to be constructed first for convenience, since the skirting board is divided into upper and lower skirting boards and skirting fixtures, the construction can be set up conveniently. ,
At the same time, it leads to shortening of construction time.
