Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a removable construction material (a skirting board, a rim, etc.) used in apartments, condominiums, individual houses and the like.

[0002]

2. Description of the Related Art Generally, in a building, a "skirting board" is attached to a corner between a wall and a floor, and a "surrounding edge" is attached to a corner between a wall and a ceiling. And "surrounding edge" is called "artificial material".

As shown in FIG. 14, a conventional skirting board 1 is formed of wood or the like into a solid long plate shape. When the skirting board 1 is attached to the corners between the wall 2 and the floor 3, the skirting board 1 is bonded to the cloth 5 attached to the inner wall base material 4, and then the skirting board 1 is hidden. It was fixed to the inner wall base material 4 by 6.

On the other hand, as shown in FIG. 15, the conventional peripheral edge 7 is formed of wood or the like into a solid long plate shape. Then, when attaching the peripheral edge 7 to the corner between the wall 2 and the ceiling 8, the peripheral edge 7 is adhered to the cloth 5 attached to the inner wall base material 4, and then the peripheral edge 7 is a hidden nail. It was fixed to the ceiling base material 9 by 6.

[0005]

In the case of the conventional work material, the work material is adhered to the cloth 5 regardless of whether the baseboard 1 or the peripheral edge 7 is used. Therefore, when removing the work material, the work material is removed. There was no choice but to destroy it, and it was not possible to recycle the removed material.

Further, when the work material is removed in the remodeling work, the cloth 5 soiled with the adhesive material must be replaced, but it is extremely difficult to peel the cloth 5 from the inner wall base material 4, so that the inner wall base material is eventually removed. I had to replace material 4 together. Therefore, there was a problem that the construction period of the remodeling was long and the cost was high.

Further, since some adhesives contain VOC, there is a problem that the indoor environment is deteriorated by the volatilization thereof.

[0008] Therefore, a main object of the present invention is to provide a work material which can be easily recycled, can shorten the period of the remodeling work and can reduce the cost, and can prevent the deterioration of the indoor environment.

[0009]

SUMMARY OF THE INVENTION The present invention is a construction material which is attached to a corner between a first surface and a second surface orthogonal to each other in a building, and one surface of which is abutted against the first surface. A base portion having a plate-shaped base body, a fixture insertion hole provided in the base body, and a first locking portion provided on the other surface of the base body; and a cover body that covers the other surface of the base body. The work material is provided with a cover portion provided on the cover main body and having a second locking portion that is engaged with the first locking portion.

When mounting the work material, a fixing tool such as a nail or a screw is inserted through the fixing tool insertion hole of the base section, and the base section is fixed to the first surface (wall or the like) by the fixing tool. And
The cover part is attached to the base part by engaging the second locking part of the cover part with the first locking part of the base part.

[0011]

According to the present invention, since no adhesive is used when attaching a work material to a wall or the like, there is no concern that the cloth attached to the wall or the like is contaminated with the adhesive. Therefore,
Even if the work material is removed, it is not necessary to replace the cloth and the inner wall base material, and thus it is possible to shorten the period for the remodeling work and reduce the cost.

Further, since the work material can be removed from the wall or the like simply by removing the fixing tool, the work material can be easily recycled without damaging the work material.

Further, since no adhesive is used, there is no concern that the indoor environment will be deteriorated by VOC.

Here, the wall 12 (FIG. 3) is constituted by an inner wall base material 28 fixed to the furring strip 26 and a pillar (not shown), a cloth 30 attached to the inner wall base material 28, and the like. The floor 14 (FIG. 3) is composed of a floor base material 32, a floor finish material 34 attached to the floor base material 32, and the like.

The base portion 18 (FIGS. 1 and 2) is made of a synthetic resin such as polypropylene, and is a long plate-shaped base whose one surface is in contact with the wall 12 (FIG. 3) as the first surface. Includes body 36. At one end portion (lower end portion) and the other end portion (upper end portion) of the base body 36 in the width direction, protrusions 36a and 36b protruding toward the other surface side are formed, and the tip end of the protrusion 36b has a cover portion. It is inclined downward so as to be easily fitted with 20.

A plurality of fastener insertion holes 40, through which fasteners 38 (FIG. 3) such as nails or screws are inserted, are formed in the base body 36 at intervals in the longitudinal direction. Each fixture insertion hole 40 is a long hole extending in the height direction (width direction) of the base body 36 so that the fixing position by the fixture 38 (FIG. 3) can be adjusted in the height direction.

Then, on the other surface of the base body 36, two recesses 42 as first locking portions are formed. Each recess 42 has two ridges 42 a and 42 b extending parallel to the longitudinal direction of the base body 36.
Two striations 42c (FIG. 1) having a substantially semicircular cross section are formed on the opposing surfaces of 2b.

The cover portion 20 is made of a synthetic resin such as polypropylene and includes a cover body 44 that covers the other surface of the base body 36. At one end (lower end) and the other end (upper end) of the cover body 44 in the width direction, ridges 44a and 44b protruding toward one surface are formed.

On one surface of the cover body 44, the second
Two ridges 46 are formed as locking portions. Each ridge 4
6 is a fitting plate 46 fitted into the recess 42 of the base portion 18.
Two protrusions 46b having a substantially semicircular cross section are formed on both upper and lower surfaces of the fitting plate 46a including a.

The connecting portion 22 includes the base portion 18 and the cover portion 2.
Connects with 0, soft resin (elastomer, etc.)
Alternatively, it is formed in a band shape from a soft material such as soft rubber. Then, one widthwise end of the connecting portion 22 is connected to the protrusion 36a of the base portion 18, and the other widthwise end thereof is connected to the protrusion 44a of the cover portion 20.

The elastic sealing material 24 seals the gap between the lower end of the cover 20 and the floor 14 (FIG. 3), and is formed into a tubular shape by a soft material such as soft resin (elastomer) or soft rubber. It is formed. Then, the elastic sealing material 24
Is connected to the lower end of the cover portion 20.

In manufacturing the fabrication material 10, first, a long product including the base portion 18, the cover portion 20, the connection portion 22 and the elastic sealing material 24 is continuously formed by extrusion molding of a synthetic resin material. . Then, this long object is cut into a length corresponding to the width of the wall 12, and a fixture insertion hole 40 is formed at a predetermined position of the base portion 18.

In this embodiment, since the resin material forming the base portion 18 and the cover portion 20 is different from the resin material forming the connecting portion 22 and the elastic sealing material 24, a so-called two-color extrusion method is used as an extrusion molding method. The law is adopted.

When attaching the work material 10 to the entry corner portion 16, first, as shown in FIG. 4, the cover portion 20 is opened and the bottom portion of the elastic sealing material 24 is brought into contact with the floor (second surface) 14. In this state, the base portion 18 is positioned with respect to the wall (first surface) 12.

Subsequently, as shown in FIG. 5, a fixing tool 38 such as a nail or a screw is inserted into a fixing tool insertion hole 40 of the base portion 18, and this is fixed to the wall 12 by using a tool such as a hammer or a screwdriver. And embed it. Each fixture insertion hole 40,
Because of the elongated hole extending in the height direction, the position of the base portion 18 in the height direction can be corrected until just before the complete fixing of the base portion 18 is completed.

When the fixing of the base portion 18 is completed, as shown in FIG. 6, the cover portion 20 is closed, and the projection (second engaging portion) of the cover portion 20 is formed in the recess (first locking portion) 42 of the base portion 18. (Stop portion) 46 is engaged. That is, the groove 42c and the protrusion 46b
Mating with. The cross sections of the groove 42c and the protrusion 46b are
All of them have a substantially semi-circular shape, so that they can be fitted and removed easily.

According to this embodiment, the wall 12 is provided with the material 10 for construction.
Since no adhesive is used to attach the wall 12
There is no concern that the cloth 30 attached to the will be soiled with the adhesive. Therefore, even if the work material 10 is removed, it is not necessary to replace the cloth 30 and the inner wall base material 28,
The period for renovation work can be shortened and the cost can be reduced. Further, there is no concern that the indoor environment will be deteriorated by the VOC contained in the adhesive material.

Then, by removing the fixing tool 38, the work material 1
Since 0 can be easily removed, it can be easily recycled.

Further, since the base portion 18 and the cover portion 20 are connected by the connecting portion 22, the number of parts is reduced, the packing workability is good, and the loss of parts (the base portion 18 or the cover portion 20) is avoided. it can.

Further, the base portion 1 is formed by the fixture insertion hole 40.
Since the height of 8 can be adjusted, the mounting position of the work material 10 can be optimally set even when the floor is raised during the reform.

Further, since the elastic sealing material 24 is connected to the lower end of the cover portion 20, it is possible to prevent air from leaking from the gap between the wall 12 and the floor 14, and to improve the airtightness of the room. Further, it is possible to prevent dust and dirt from accumulating in the gap between the work material 10 and the floor 14.

In the above-mentioned construction material 10, the whole is integrally formed by extrusion molding of synthetic resin, but both or one of the base portion 18 and the cover portion 20 is made of a material other than synthetic resin such as wood or aluminum. The connection portion 22 and the elastic sealing material 24 may be attached later.

Wood that can be used for the construction material 10 includes sawn wood, plywood, wood fiberboard (IB, MDF, etc.), wood shavings (particle board, strand board, OSB).
Etc.), laminated wood, laminated veneer wood or composite materials thereof. Also, for these woods, decorative paper,
A decorative material such as a decorative resin-impregnated paper, a decorative synthetic resin sheet, a decorative veneer, or the like may be attached, or colored coating, transparent coating, pattern printing, or the like may be applied. Further, painting or printing may be performed on the decorative material.

Further, in the above-mentioned construction material 10, the base portion 1
8 and the cover portion 20 are connected by the connecting portion 22, but the base portion 18 and the cover portion 20 may be formed independently as in the case of the work material 48 shown in FIG. 7, for example.

Further, in the above-mentioned work material 10, the base portion 1
8 is formed with a recess (first locking portion) 42 and a cover 20 is formed with a ridge (second locking portion) 46. For example, as in the work material 50 shown in FIG. The ridge (first locking portion) 46 may be formed on the cover 18, and the recess (second locking portion) 42 may be formed on the cover 20.

In this case, as shown in FIG. 9, since the cover portion 20 can be formed thick, the cover portion 2
0 can be integrally formed of natural wood or the like. However,
In this case, using a fixture 52 such as a nail or screw,
It is necessary to fix the elastic sealing material 24 to the cover portion 20.

Then, as shown in FIG.
8 and the cover portion 20 in the space 54 between the wire rod locking portion 56
May be formed, and the wire rod 58 such as a telephone line, a power supply line or a LAN cable may be locked to the wire rod locking portion 56.

In this case, the space 54 can be effectively used as a wiring space, and the entanglement of the wire rod 58 can be eliminated.
However, the shape, number, position, etc. of the wire rod locking portions 56 can be changed as appropriate, and for example, one wire rod locking portion 56 having a substantially U-shaped cross section may be formed in the cover portion 20.

Further, the cross-sectional shape of the elastic sealing material 24 may be changed appropriately as shown in FIG. That is,
It may be formed in a substantially C shape as in (A) or may be formed in a jagged shape as in (B). Then, as in (C), a shape having a plurality of substantially semicircular protrusions 24a may be formed. With the shape of (B) or (C), since the adhesiveness between the elastic sealing material 24 and the floor 14 becomes higher, higher airtightness can be obtained.

Further, the height (width) of the work material 10 may be appropriately changed. When lowering the height of the work material 10, for example, as shown in FIG. 12, one recess 42 and one protrusion 46 may be formed.

If the construction material 10 has a low height, it can be used as it is as a "surrounding edge" as shown in FIG. 13, for example. That is, the present invention can be applied to both the skirting board and the surrounding edge, and the basic configuration does not change depending on which one is applied. Therefore, even when the present invention is applied to the "surrounding edge", the "skirting board"
Various configurations (FIGS. 7 to 11) described above can be adopted.
