Description

The present invention relates to a timber provided at a corner of a wall surface and a floor surface of a building.

In general, skirting boards are provided at the corners of the wall surface and the floor surface facing the living room of the building (see Patent Document 1 and the like). The skirting cloth is attached to the lower edge of the wall surface, and the lower end surface thereof faces the upper surface of the end portion of the floor material.
Flooring materials such as flooring expand and contract due to changes in humidity and temperature. If the expansion / contraction is prevented, the floor material will bend. In order to prevent this, a slight gap is set between the lower end surface of the purse and the floor material to cut off the edges. On the other hand, if the gap is too large, the appearance will be poor.
In order to ensure the accuracy of the size of the gap, when constructing a building, a wall and a floor are usually constructed, and then a skirting board is installed with reference to the floor surface, that is, the upper surface of the floor material.

Japanese Unexamined Patent Publication No. 2019-0392229 (0016, FIG. 1)

Depending on the construction situation, it may be considered efficient to shorten the construction period if the timber can be installed on the wall before laying the flooring such as flooring. However, with the conventional method, it was difficult to install the timber with high accuracy unless the actual floor surface was used as a reference.
In view of such circumstances, it is an object of the present invention to enable the skirting board to be installed accurately on the floor surface even before the floor material is laid, and to enhance the flexibility of construction.

In order to solve the above problems, the present invention is a drawwood provided at a corner between a wall surface and a floor surface facing a space inside a building.
A skirting board body that extends along the lower edge of the wall surface, the front surface of which faces the space inside the building, and the back surface of which is attached to the wall surface.
A first leg piece that is formed thinner than the skirt body and hangs down from the back side portion of the lower end of the skirt body by a predetermined length.
A portion of the lower end of the skirting board body that is closer to the front surface of the first leg piece and the first leg piece portion define a receiving portion of an end portion of the floor material that constitutes the floor surface. It is characterized by being done.
Preferably, the hanging length of the first leg piece is set or selected according to the thickness of the floor material to be laid. At the construction site, for example, the purse is installed on the lower edge of the wall surface while the lower end of the first leg piece is abutted against the floor base. As a result, the timber can be installed at an appropriate height with respect to the floor surface even before the floor material is laid. After that, when laying the floor material, the end portion of the floor material is inserted into the receiving portion on the lower side of the purse body.

A flexible second leg piece, which is formed thinner than the skirt body and hangs down from the front side portion at the lower end portion of the skirt body, is further provided.
It is preferable that the hanging length of the second leg piece is equal to or less than the hanging length of the first leg piece.
By making the second leg piece portion flexible, the end portion of the floor material can be inserted into the receiving portion while bending and deforming the second leg piece portion toward the first leg piece portion side. Moreover, the insertion amount can be adjusted by using one part of the second leg as a guide.
Furthermore, by setting the hanging length of the second leg piece to be equal to or less than the hanging length of the first leg piece, the lower end of the first leg piece is abutted against the floor base, and the width strip is pushed in the height direction. The second leg piece can be kept out of the way when positioning.
It is preferable that the hanging length of the first leg piece is equal to or larger than the sum of the thickness of the second leg piece and the thickness of the floor material.

It is preferable that notch grooves are formed at the corners between the upper end surface of the skirting board body and the back surface so as to extend in the longitudinal direction of the skirting board body.
By doing so, the entire wall is slightly separated from the wall surface to the front side, and it looks as if it is floating, which enhances the design. Even if there are some gaps between the back surface of the lumber and the wall surface, the gaps are integrated with the notch groove and become inconspicuous.

According to the present invention, the timber can be installed with high accuracy on the floor surface even before the floor material is laid, and the flexibility of construction can be enhanced.

FIG. 2 is a cross-sectional view of the timber before the installation. FIG. 3 is a perspective view of the timber before the installation. FIG. 4A is a cross-sectional view of the corner portion at the stage where the skirting board is installed on the wall before the floor material is laid. FIG. 4B is a cross-sectional view of the corner portion showing a state in which the floor material is subsequently laid.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a corner portion 3c of a wall 1 and a floor 2 that define an interior space 3 in a building. The building is not particularly limited, and examples thereof include a detached house, an apartment house, an office building, a commercial facility, a factory, a school, and a hospital. The space 3 in the building is not particularly limited, and examples thereof include a living room, a corridor, a work room, a classroom, a hospital room, and a toilet.
The floor 2 includes a floor base 2b such as a slab and a floor material 4 such as flooring laid on the floor base 2b. The upper surface of the floor material 4 constitutes the floor surface 2a.

As shown in FIG. 1, a width strip 10 is provided at a corner portion 3c of the wall surface 1a and the floor surface 2a facing the building space 3 of the wall 1. The material of the skirting cloth 10 is, for example, polyethylene (PE), polypropylene (PP), acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC), or other resin. Preferably, the material of the width strip 10 is a soft resin having flexibility or elasticity.
As shown in FIG. 3, the width strip 10 is produced by extrusion molding, has a long strip shape having a constant cross-sectional shape, and is cut to an appropriate length according to the size of the wall 1. used.

Specifically, as shown in FIGS. 2 and 3, the widthpiece 10 includes a widthpiece main body 11 and leg pieces 13 and 14. The purse body 11 extends along the lower edge of the wall surface 1a with the lateral direction facing up and down and the thickness direction facing the front-rear direction orthogonal to the wall surface 1a. The front surface 11a of the purse body 11 is directed toward the space 3 in the building, and the back surface 11b is directed toward the wall surface 1a. The upper end surface 11e of the purse body 11 is a rounded surface that rises toward the back surface 11b side while drawing an arc from the front surface 11a side.
The front surface 11a and the upper end surface 11e are decorative surfaces.

As shown in FIG. 2, a notch groove 11d is formed at a corner portion between the upper end surface 11e and the back surface 11b of the purse body 11. The notch groove 11d is opened in the upper end surface 11e and the back surface 11b, and extends over the entire length of the skirting body 11 in the longitudinal direction. The width We on the upper end surface 11e side of the notch groove 11d is sufficiently smaller than the width Wb on the back surface 11b side (We << Wb). In other words, the notch groove 11d is deep in the vertical direction and shallow in the thickness direction (horizontal direction in FIG. 2).
Inside the purse body 11, two (plurality) hollow portions 11c are formed at the top and bottom. As a result, the amount of resin per unit length of the width strip 10 is reduced, and the material cost is reduced. In addition, the muffling effect is enhanced. The number of hollow portions 11c is not limited to two, and may be only one or three or more.

As shown in FIG. 2, the first leg piece portion 13 and the second leg piece portion 14 are integrally provided at the lower end portion of the width strip main body 11.
The first leg piece portion 13 hangs down (extends straight downward) by a predetermined length from a portion on the back surface side (left side in FIG. 2) at the lower end portion of the width strip main body 11. The back surface 13b of the first leg piece 13 is flush with the back surface 11b of the drawstring body 11. The first leg piece portion 13 is formed to be sufficiently thinner than the width strip main body 11. The thickness of the first leg piece 13 is less than a fraction of the thickness of the width strip main body 11.
The hanging length of the first leg piece 13 is set or selected according to the thickness of the floor material 4. In Specifically, droop length L ₁₃ of the first leg portion 13, the flooring 4 thickness t _{4 (FIG.} 1) and the more the total thickness of the thickness t ₁₄ of the second leg piece part 14 Yes (L ₁₃ ≧ t ₄ + t ₁₄ ), preferably slightly larger than the total thickness (L ₁₃ > t ₄ + t ₁₄ ).

As shown in FIG. 2, the second leg piece portion 14 hangs down from a portion on the front side (right side in FIG. 2) of the lower end portion of the purse body 11 with respect to the first leg piece portion 13. The hanging length of the second leg piece 14 is not less than or equal to the hanging length of the first leg piece 13, and is preferably shorter than the hanging length of the first leg piece 13. The second leg piece 14 is separated from the first leg piece 13 on the front side. The front surface of the second leg piece 14 is flush with the front surface 11a of the width strip main body 11. The second leg piece 14 is sufficiently thinner than the purse body 11, and more preferably is thinner than the first leg piece 13. The second leg piece portion 14 has flexibility and can be easily bent and deformed.

As shown in FIG. 2, a receiving portion 12 of the end portion 4e of the floor material 4 is formed on the lower side of the skirting board main body 11. The receiving portion 12 is defined by a portion on the lower end portion of the width strip main body 11 on the front side of the first leg piece portion 13 and the first leg piece portion 13. The receiving portion 12 of the widthpiece 10 before construction is separated from the space in front (on the right side in FIG. 2) by the second leg piece portion 14.

As shown in FIG. 1, in the constructed width strip 10, the back surface 11b of the width strip main body 11 and the back surface 13b of the first leg piece portion 13 are addressed to the wall surface 1a and via an adhesive (not shown). It is pasted. In addition, the lower end of the first leg piece 13 is in contact with the floor base 2b. The end portion 4e of the floor material 4 is received in the receiving portion 12. Following the floor material end portion 4e, the second leg piece portion 14 is deformed so as to bend to the back surface side (left side in FIG. 1).
A margin gap 12e in the vertical direction is formed between the lower end surface of the skirting board main body 11 and the upper surface of the floor material end portion 4e. A margin 12b in the front-rear direction (left-right direction in FIG. 1) is formed between the first leg piece portion 13 and the side end surface of the floor material end portion 4e.

The corner portion 3c including the width bar 10 is constructed as follows.
In advance, the hanging length of the first leg piece 13 of the drawstring 10 is set or selected according to the thickness of the floor material 4 to be laid.
As shown in FIG. 4A, the skirting board 10 is installed along the lower edge of the wall surface 1a after the construction of the wall 1 and the floor base 2b and before the laying of the floor material 4. At this time, the height of the width strip 10 is adjusted by abutting the lower end portion of the first leg piece portion 13 against the upper surface of the floor base 2b. Since the second leg piece 14 has a shorter hanging length than the first leg piece 13, it does not hit the floor base 2b and does not interfere with the height adjustment.
Next, the back surfaces 11b and 13b, which are flush with the width strip main body 10 and the first leg piece portion 13, are attached to the lower edge portion of the wall surface 1a via an adhesive (not shown).
As a result, even before the floor material 4 is laid, the purse 10 can be accurately installed at an appropriate height with respect to the floor surface 2a shown by the alternate long and short dash line in FIG. 4A. Therefore, the flexibility of construction can be increased.

Subsequently, as shown in FIG. 4B, the floor material 4 is installed. As shown by the white arrow line in the figure, the end portion 4e of the floor material 4 is inserted into the receiving portion 12 from the front (right side in the figure). At this time, the floor material 4 bends and deforms the flexible second leg piece 14 toward the back surface (left side in the figure). Therefore, the second leg piece portion 14 does not interfere with the insertion operation of the floor material end portion 4e.
Further, the amount of insertion of the end portion 4e of the floor material 4 into the receiving portion 12 can be adjusted by using the second leg piece portion 14 as a guide. As a result, the floor material 4 can be accurately positioned in the front-rear direction (horizontal direction in FIGS. 1 and 4B).

As shown in FIG. 1, a flexible second leg piece portion 14 that has been bent and deformed is interposed between the widthpiece main body 11 and the floor material end portion 4e. The margin gap 12e can be hidden by the second leg piece portion 14. In addition, it is possible to prevent dust from entering the margin gaps 12e and 12b.
Further, by setting the margin gaps 12b and 12e, it is possible to allow the floor material 4 to expand and contract in response to changes in humidity and temperature. By forming the second leg piece portion 14 flexibly and thinly, expansion and contraction of the floor material 4 can be reliably tolerated. This makes it possible to prevent the floor material 4 from bending and deforming.

A notch groove 11d is interposed between the upper end surface 11e of the widthpiece main body 11 and the wall surface 1a over the entire length of the widthpiece 10. For this reason, the entire width piece 10 appears to float slightly away from the wall surface 1a toward the front side, and the design is enhanced. Even if there are some gaps between the back surface 11a of the width strip 10 and the wall surface 1a, the gaps are integrated with the notch groove 11d and become inconspicuous.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, at least the second leg piece 14 of the first and second leg pieces 13 and 14 may be omitted. The first and second leg pieces 13 and 14 do not necessarily have to be continuous over the entire length of the width strip 10, and may be provided intermittently.

The present invention can be applied to a purse such as a room corner of a building.
