Description

TECHNICAL FIELD The present invention relates to a stair finishing material that decorates the surface of a stair base.

Conventionally, in various houses such as individual detached houses and condominiums, stairs are installed at the initial stage of construction. This type of stairs is constructed using natural wood, decorative plywood or laminated wood, and after installation is complete, the owner uses the stairs as they are. In other words, it can be said that the stairs that became the final finished product have been installed from the initial stage of construction.
In this case, although the staircase is the final finished product, the surrounding construction process will proceed after installation, so various workers such as carpenters and interior workers will come in and out, and many people will go up and down the staircase. Will be working. Therefore, in order to prevent the stairs from being damaged by the contractor, the stairs are protected and protected. As a method of curing the stairs, a method of mounting a curing plate made of metal, plywood, plastic, or the like on the stairs, or covering the stairs with a curing sheet such as a synthetic resin sheet is adopted (Patent Documents 1 and 2, etc.). ).

The staircase finishing material A of the present invention is provided as a set product of a stepping finish material 1, a nose finish material 2, and a skirting board finish material 4 (preferably, a rise finish material 3).

<Treading material>
FIG. 2A is a plan view of the step finish material 1 viewed from the front side, FIG. 2B is a plan view of the step finish material 1 viewed from the back side (rear view), and FIG. It is an enlarged version. In FIGS. 2A and 2B, the central portion is omitted since it has the same structure as the both side portions. Hereinafter, in other drawings in which the central portion is omitted, the structure of the central portion omitted in the drawing is the same as the structure of both side portions thereof.
The tread finishing material 1 is a member that covers the tread surface portion of the stairs base and is used for finishing the surface of the tread surface portion. The tread material 1 is used by being attached to the surface of the tread surface portion of the stairs base through an attaching means. Examples of the attaching means include an adsorption part, a pressure-sensitive adhesive layer, and an adhesive layer.
The trampling material 1 is formed, for example, in a substantially rectangular shape in plan view so as to conform to the shape of the tread surface portion for one step of the stairs base. Further, the length in the longitudinal direction of the tread material 1 is formed so as to match the length in the width direction of the tread surface portion for one step.
The trampling material 1 may be a hard plate-shaped body, but it is preferably composed of a flexible sheet body from the viewpoint of easy construction. In the present specification, the “flexible sheet body” means, for example, a sheet body that can be wound around a core material having a diameter of 10 cm in a roll shape.
The trampling material 1 of the illustrated example is formed of a flexible sheet body.
The thickness of the trampling material 1 is not particularly limited and is, for example, 1 mm to 5 mm, preferably 1.5 mm to 3 mm.

The step finish material 1 is composed of a flexible sheet body 11 and a suction portion 12 (pasting means) provided on the back surface of the sheet body 11.
For example, as shown in FIG. 2C, the sheet body 11 has a back layer 111, an intermediate base material layer 112, and a surface layer 113 in order from the back surface side to the front surface side. The surface of the surface layer 113 is smooth, but embossed irregularities may be formed on the surface of the surface layer 113 as necessary.
The back layer 111 may be a single layer, but preferably has a back side base material layer 1111 and a back side resin layer 1112, and a plurality of these may be laminated. In the illustrated example, the back layer 111 is formed by laminating a back side base material layer 1111 and a back side resin layer 1112 in order from the back side to the front side.
The surface layer 113 may be one layer, but preferably, two or more selected from a scratch prevention layer 1133, a protective layer 1132, a decorative layer 1131 and a surface side resin layer are laminated. In the illustrated example, the surface layer 113 is formed by laminating a decorative layer 1131, a protective layer 1132, and a scratch prevention layer 1133 in order from the back surface side to the front surface side.

The back side resin layer 1112 and the front side resin layer may be foamed or non-foamed independently of each other, but are preferably formed of foam. As a result, it is possible to provide the stepping finishing material 1 with unobstructed concealment, anti-slip properties and sound deadening properties, and when the skirting board finishing material 4 is attached in contact with the surface of the stepping finishing material 1 at the time of construction, the skirting board finishing material 4 Can bite into the seat body 11 to build a stronger staircase finishing structure.
It is preferable that the back side resin layer 1112 and the front side resin layer are each independently a resin layer containing a soft synthetic resin as a main component resin. Examples of the soft synthetic resin include vinyl chloride resins such as vinyl chloride and vinyl chloride-vinyl acetate copolymers; polyolefin resins; urethane resins; vinyl acetate resins such as ethylene-vinyl acetate copolymers; olefin elastomers, Various elastomers such as styrene-based elastomers; rubber and the like. These may be used alone or in combination of two or more. It is preferable that the back side resin layer 1112 and the front side resin layer are resin layers containing a vinyl chloride resin as a main component resin because they are inexpensive and have excellent flexibility and durability.
As the back side base material layer 1111 and the intermediate base material layer 112, felt, non-woven fabric, woven fabric, paper and the like are independently used.
The scratch prevention layer 1133 is formed of, for example, an ultraviolet curable resin, the protective layer 1132 is formed of a soft synthetic resin such as vinyl chloride resin, and the decorative layer 1131 is provided with a design, for example. The soft synthetic resin layer, the design ink, the design transfer film, etc. are formed.

The suction part 12 is provided for adsorbing the tread material 1 to the tread surface portion and adhering the tread material 1 thereto. That is, the adsorbing portion 12 fixes the tread surface portion 1 so that the tread material 1 does not shift in the surface direction and the vertical direction of the tread surface portion.
The suction unit 12 may be provided in a solid shape on the back surface of the sheet body 11 (not shown). In the illustrated example, the suction portion 12 is not provided on the entire back surface of the sheet body 11, but is partially provided on the back surface of the sheet body 11. That is, as for the back surface of the step finish material 1, the back surface of the sheet body 11 is partially exposed. In order to clearly show the formation range of the suction portion 12, in FIG. 2B, the suction portion 12 is shaded for convenience.
In the illustrated example, the suction portion 12 is formed of a plurality of convex shapes projecting from the back surface of the sheet body 11, for example, a plurality of convex shapes in a plan view that are vertically projected from the back surface of the sheet body 11. .. Each of the belt-shaped convex suction portions 12 extends in the first direction of the seat body 11, and the plurality of suction portions 12 are arranged in parallel in the second direction of the seat body 11. In the step finishing material 1 formed in a substantially rectangular shape in a plan view, the first direction may be the longitudinal direction as shown in the drawing, or may be the lateral direction, or is inclined with respect to the longitudinal direction. It may be in the direction. As shown in FIG. 2( b ), it is preferable that the suction portion 12 has a plurality of convex shapes extending in the longitudinal direction of the seat body 11 to stabilize the tread material 1 on the tread surface portion. It can be attached.

Examples of the material for forming the adsorbing portion 12 include flexible foamed resin and soft rubber. In particular, as a material for forming the adsorption portion 12, a foamed resin having flexibility is preferable. The flexible foamed resin has a porous structure having a plurality of fine holes on its back surface. The foamed resin may have either an open cell structure or a closed cell structure, but the open cell structure is preferable because it has a sufficient sucker function and exhibits a high adsorption force. The material of the foamed resin is not particularly limited, and examples thereof include thermoplastic resins such as acrylic resin, urethane resin, ethylene-vinyl acetate, polyvinyl alcohol, polyvinyl acetate, epoxy resin, acrylate ester, and polyester. It is preferable to use a foamed acrylic resin obtained by foaming an acrylic resin as the material for forming the adsorption portion 12 because of its excellent adhesion. The foaming ratio of the foamed resin is not particularly limited, but is preferably 1.1 times to 6 times, and more preferably 1.6 times to 2 times from the viewpoint of sufficiently adhering to the stairs base and making it difficult to cause material destruction. It is more preferably 1.6 times or more and less than 2 times.
The protruding height of the convex suction portion 12 is not particularly limited and is, for example, 0.1 mm to 0.5 mm.

Although the sheet main body 11 of the above-mentioned foot finish material 1 has the back layer 111, the intermediate base material layer 112, and the front layer 113, it may be composed of only the front layer 113 and the back layer 111, or the front layer 113 and the middle layer. It may be composed of only the base material layer 112, or may be composed of only the surface layer 113.
Further, although the above-mentioned step finish material 1 is provided with the suction portion 12 on the back surface of the sheet main body 11, it may not have the suction portion 12. In the step finishing material 1 that does not have the adsorption portion 12, an adhesive layer may be provided on the back surface of the sheet body 11 as an attaching means.
In the present specification, the "adhesive layer" includes a double-sided pressure-sensitive adhesive tape (a double-sided pressure-sensitive adhesive tape refers to a thin web having a pressure-sensitive adhesive applied to both sides) in addition to a layer formed by directly coating the pressure-sensitive adhesive. Those formed by pasting are also included. The thickness of the “adhesive layer” described in the present specification is not particularly limited, but is, for example, 0.1 mm to 0.5 mm. When each member such as the step finish material 1 is provided with an adhesive layer, release paper is usually temporarily attached to the adhesive surface to protect the adhesive surface (the release paper is not shown).

<Raised finish material>
FIG. 3A is a plan view of the rise finish material 3 viewed from the surface side, and FIG. 3B is an enlarged cross-section of the rise finish material 3.
The rise finish material 3 is a member used to cover the rise surface portion of the stairs base and finish the surface of the rise surface portion. The rise finish material 3 is used by being attached to the surface of the rise face portion of the stairs base through an attaching means such as an adhesive layer or an adhesive layer.
The rise finish material 3 is, for example, formed in a substantially rectangular shape in plan view so as to match the shape of the rise surface portion for one step of the stairs base. Further, the length in the longitudinal direction of the rise finish material 3 is formed so as to match the length in the width direction of the rise surface portion for one step.
The rise finish 3 may be a hard plate, but is preferably made of a flexible sheet from the viewpoint of easy construction.
The riser finishing material 3 in the illustrated example is composed of a soft sheet body.
The thickness of the rise finish material 3 is not particularly limited and is, for example, 1 mm to 5 mm, preferably 1.5 mm to 3 mm.

The rise finish 3 includes a sheet body 31 and an adhesive layer 32 (pasting means) provided on the entire back surface of the sheet body 31. The release paper that protects the adhesive surface of the adhesive layer 32 is not shown.
The details of the seat body 31 of the rise finish material 3 are the same as those in the above <Treading finish material>. Therefore, the description of the seat body 31 of the rise finish material 3 is as follows: "Tread finish material 1", "Seat body 11", and "Tread surface portion" in the section of <Tread finish material> A specific example of the sheet body 31 of the rise finish material 3 is described here by replacing the terms "sheet body 31" and "chamfering surface portion".

In FIG. 3, the adhesive layer 32 is provided on the back surface of the sheet body 31 of the rise finish material 3, but the rise finish material 3 without the adhesive layer may be used. Further, a suction portion 12 similar to that of the step finish material 1 may be provided on the back surface of the seat body 31 of the rise finish material 3.
Further, the seat body 31 of the rise finish material 3 may be made of a material different from that of the step finish material, and may be formed of, for example, wallpaper or a tack sheet.

<Nosing finish>
FIG. 4A is a perspective view of the nosing finishing material 2, FIG. 4B is a plan view of the nosing finishing material 2 as seen from the upper plate portion side, and FIG. 4C is a right side view thereof.
The nosing finishing material 2 is a member used for covering the nosing portion of the stairs base and finishing the surface of the nosing portion. The nosing finishing material 2 is used, for example, by being attached to the surface of the nosing portion of the stairs base through an attaching means such as an adhesive layer or an adhesive layer. The pressure-sensitive adhesive layer does not need to be dried and can be fixed in a short time, which facilitates construction. The adhesive layer can be reattached at the time of construction to facilitate position adjustment, and can be firmly fixed after drying.
The nosing finishing material 2 is formed, for example, in a substantially U-shape in a side view so as to match the shape of the nosing portion for one step of the stairs base. In addition, the nosing finishing material 2 is formed in a long shape having a length that matches the widthwise length of the nosing portion for one step.
The nosing finishing material 2 may be soft, but is preferably hard in terms of easy construction.
In addition, the nosing finishing material 2 may be composed of a laminated body of two or more layers having a soft layer and a hard layer. For example, the stair nosing finishing material 2 in which the lower layer is a hard layer and the upper layer is a soft layer is preferable because it can improve the slip resistance when climbing stairs while maintaining the workability.

In the present specification, "hard" means a Shore D hardness of 60 or more, and "soft" means less than 60. The Shore D hardness can be measured according to JIS K 7215:1986 using a Durometer type D Asker rubber hardness meter (manufactured by Kobunshi Keiki Co., Ltd.). The hard material can be defined by the Shore D hardness as described above, but may be either one that can be bent manually or one that cannot be bent manually.
The nosing finishing material 2 of the illustrated example is made of a hard material, preferably a hard material that can be bent manually.
The material for forming the hard nosing finish 2 is not particularly limited, and examples thereof include hard synthetic resin, metal, wood, etc. However, hard synthetic resin is preferable because it can be easily molded. The soft nosing finish 2 is made of, for example, soft synthetic resin or rubber.

The nosing finishing material 2 includes an upper plate portion 21 that covers the upper surface of the nosing portion of the stairs, a front plate portion 22 that covers the front surface of the nosing portion of the stairs, and a lower plate portion 23 that covers the lower surface of the nosing portion of the stairs. , And they are integrally formed.
For example, the upper plate portion 21 and the front plate portion 22 are connected to each other in a substantially right angle shape, and the front plate portion 22 and the lower plate portion 23 are connected to each other in a substantially right angle shape. Preferably, the nosing finishing material 2 is a molded product in which the upper plate portion 21, the front plate portion 22, and the lower plate portion 23 are integrally molded with one forming material. The upper plate portion 21 is formed in a substantially rectangular shape so as to conform to the shape of the upper surface of the nosing portion, and the front plate portion 22 is formed in a substantially rectangular shape so as to conform to the shape of the front surface of the nosing portion. The plate portion 23 is formed in a substantially rectangular shape so as to match the shape of the lower surface of the nosing portion. Therefore, the nosing finish material 2 is a long U-shape in which a substantially U-shape in a side view is continuous.
The lengths in the lateral direction of the upper plate portion 21, the front plate portion 22, and the lower plate portion 23 are not particularly limited and can be set appropriately. For example, the short-side length of the upper plate portion 21 (inside dimension reference) is 10 mm to 100 mm, the short-side length of the front plate portion 22 (inside dimension reference) is 20 mm to 70 mm, and the lower plate The length of the portion 23 in the short side direction (inside dimension standard) is 10 mm to 100 mm.

An uneven surface is formed on the surface of the upper plate portion 21 as needed. The uneven surface is for preventing the sole from slipping. In the illustrated example, the uneven surface is formed by forming a plurality of convex portions 24 on the surface of the upper plate portion 21. Although not particularly shown, a concave portion may be formed opposite to the convex portion 24, and even in that case, an uneven surface can be similarly formed on the upper plate portion 21.
The uneven surface may be formed on the entire surface of the upper plate portion 21, but since the end surface of the skirting board finishing material 4 can be brought into contact with the surface of the upper plate portion 21 without a gap, the uneven surface is It is preferable that the upper plate portion 21 is formed in a region of the surface of the upper plate portion 21 excluding both side portions 21x, 21x.
In the area excluding both sides 21x, 21x of the upper plate portion 21, as shown in FIGS. 4(a) and 4(b), there are one or more flat surfaces 21y continuous in the lateral direction. The protrusions 24 may be formed in this state, or the protrusions 24 may be formed so as to be substantially continuous with each other (not shown). Since the convex portion 24 is formed in the region excluding the both side portions 21x, 21x while having the flat surface 21y continuous in the lateral direction, it becomes easier to sweep out dust during cleaning. On the other hand, when the convex portions 24 are formed substantially continuously in a region excluding both side portions 21x, 21x (that is, the convex portion 24 does not have the flat surface 21y continuous in the lateral direction). In the case where the nose finish is formed), the nosing finish 2 can be easily manufactured by extrusion molding or the like.
Moreover, you may form the convex part 24 with foaming resin. The convex portion 24 made of foamed resin is flexibly deformed by applying pressure. For this reason, the nosing finishing material 2 in which the convex portion 24 made of foamed resin is formed in the region including both side portions 21x, 21x of the upper plate portion 21 has the end face of the skirting board finishing material 4 on the surface of the upper plate portion 21. It can be abutted without a gap.
The height of the convex portion 24 (or the depth of the concave portion) is not particularly limited and is, for example, 0.3 mm to 1 mm.

The thicknesses of the upper plate portion 21, the front plate portion 22, and the lower plate portion 23 are not particularly limited, but independently, for example, 1 mm to 5 mm, preferably 1.5 mm to 3 mm.
In particular, the thickness of the upper plate portion 21 is preferably the same as the thickness of the step finish material 1. Since the upper plate portion 21 and the step finish material 1 have the same thickness, a step is less likely to occur at the boundary portion between the upper plate portion 21 and the step finish material 1, as will be described later, and the horizontal baseboard member 6 (baseboard is used). The end surface of the finishing material 4) can be brought into contact with both the surface of the upper plate portion 21 and the surface of the stepping finishing material 1 without any gap.
The upper plate portion 21, the front plate portion 22, and the lower plate portion 23 may all have the same thickness, or may have different thicknesses. Usually, the upper plate portion 21, the front plate portion 22, and the lower plate portion 23 are all formed to have the same thickness.

Moreover, a pressure-sensitive adhesive layer 25 or an adhesive layer is provided on the back surface of the nosing finishing material 2 as necessary. In the illustrated example, an adhesive layer 25 is provided on each of the back surfaces of the upper plate portion 21, the front plate portion 22, and the lower plate portion 23. The release paper temporarily attached to the adhesive layer 25 is not shown.
The adhesive layer 25 may be solidly provided over the entire back surfaces of the upper plate portion 21, the front plate portion 22, and the lower plate portion 23. The upper plate portion 21, the front plate portion 22, and the lower plate portion may be provided. It may be independently provided on the back surface of 23. In the illustrated example, as shown in FIG. 4C, one adhesive layer 25 is provided on the back surface of the upper plate portion 21 from the edge of the upper plate portion 21 to the vicinity of the boundary with the front plate portion 22, Another pressure-sensitive adhesive layer 25 is provided in an intermediate region of the front plate portion 22, and another pressure-sensitive adhesive layer 25 is formed on the back surface of the lower plate portion 23 from the edge of the lower plate portion 23 to the front plate portion 22. Is provided up to the vicinity of the boundary.

A second joint end surface 5c is formed in contact with the second joint end surface 6c of the horizontal skirting member 6. The first joining end surface 5b is flat in a side view, and is linear in a plan view forming an obtuse angle (for example, 135 degrees) with the rise-corresponding end surface 5a. The second joining end surface 5c is flat in a side view, and is linear in a plan view forming an acute angle (for example, 45 degrees) with the rise-corresponding end surface 5a.
An adhesive layer 52 or an adhesive layer is provided on the back surface of the vertical skirting member 5 as needed. In the illustrated example, the adhesive layer 52 is provided on the entire back surface of the vertical skirting member 5. However, the adhesive layer 52 may be provided on a part of the vertical skirting member 5. For example, the adhesive layer 52 may be provided only on the peripheral portion of the vertical skirting member 5.

With reference to FIG. 6, the horizontal skirting board member 6 has a strip shape as a whole.
An end surface 6a is formed on one side of the lateral skirting member 6 in the lateral direction and is in contact with a part of the upper plate portion 21 of the step finish material 1 and the nose finish material 2. In other words, the length of the horizontal skirting board member 6 in the longitudinal direction is slightly longer than that of the step finish material 1. The end surface 6a (the end surface 6a is referred to as a stepping corresponding end surface 6a) is flat in a side view (straight in a plan view). An end surface parallel to the step-corresponding end surface 6a is formed on the side opposite to the lateral baseboard member 6 in the lateral direction.
Further, a first joint end surface 6b in contact with the first joint end surface 5b of the vertical skirting member 5 is formed on one side in the longitudinal direction of the horizontal skirting member 6, and on the opposite side in the longitudinal direction of the horizontal skirting member 6, A second joint end surface 6c is formed in contact with the second joint end surface 5c of the vertical skirting member 5. The first joint end surface 6b is flat in a side view, and is linear in a plan view forming an obtuse angle (for example, 135 degrees) with the step-corresponding end surface 6a. The second joint end surface 6c is flat in a side view, and is linear in a plan view forming an acute angle (for example, 45 degrees) with the step-corresponding end surface 6a.
An adhesive layer 62 or an adhesive layer is provided on the back surface of the horizontal skirting member 6 as necessary. In the illustrated example, the adhesive layer 62 is provided on the entire back surface of the horizontal skirting board member 6. However, the adhesive layer 62 may be provided on a part of the horizontal skirting board member 6. For example, the adhesive layer 62 may be provided only on the peripheral portion of the horizontal skirting member 6.

That is, the side wall foundation 9 and the staircase foundation 8 are in a completed state in terms of strength without any hindrance to the user moving up and down, but are in an unfinished state in appearance because they are unfinished. ..
The side wall foundation 9 is constructed of a conventionally known building material, for example, gypsum board, plywood such as a plywood board or a concrete panel (so-called control panel), concrete or the like. The stairs base 8 is also constructed of a conventionally known building material, for example, plywood such as plywood or concrete panel (so-called control panel), concrete or the like. In the example shown in FIG. 9, the tread surface portion 81 and the nose portion 82 are integrally formed of one building material (for example, a control panel), but the tread surface portion 81 and the nose portion 82 are made of different building materials. However, the nosing part 82 in front of the tread 81 may be fixed. Further, in the illustrated example, the riser surface portion 83, the tread surface portion 81, and the nose portion 82 are made of different building materials and are fixed to each other, but they may be made of one molded product.

The tread material 1 is attached to the surface of the tread surface portion 81. As described above, the tread material 1 provided with the suction portion 12 is adhered to the surface of the tread portion 81 via the suction portion 12 in close contact with the surface. The suction portion 12 is in close contact with the tread surface portion 81, but since it is not physically adhered like an adhesive or a pressure-sensitive adhesive, the stepping finishing material 1 can be easily peeled off and its position can be adjusted.
The tread material 1 may be attached to the tread portion 81 via an adhesive layer or an adhesive layer.
As shown in FIGS. 8 and 9, the rear end of the tread finishing material 1 is in contact with or in the vicinity of the tread surface portion 83, and the front end of the tread finishing material 1 is a nose portion 82 and a tread surface portion.

It may be in contact with the surface of the material 3 or located near the surface thereof. In short, the nose finish material 2 and the rise finish material 3 are attached so that the lower plate portion 23 and the rise finish material 3 cooperate to conceal the entry corner between the nose portion 82 and the rise surface portion 83. It has to be done.

In the vertical skirting member 5 of the skirting board finishing material 4, the end surface of the fitting dent 51 is in contact with the upper plate portion 21 and the front plate portion 22 in a state where the fitting dent 51 is fitted to the outside of the nosing finishing material 2. While pressing the upper plate portion 21 and the front plate portion 22 and the end face 5a corresponding to the rise contacting the surface of the rise finish material 3 to hold down the rise finish material 3, the corner portion 91 (a part of the side wall base 9) is formed. It is pasted. The fitting recess 51 may or may not be in contact with the lower plate portion 23, but as shown in FIG. 9, the end surface of the fitting recess 51 is in contact with the lower plate portion 23 so that the fitting recess 51 is stronger. The nosing finishing material 2 can be fixed to the.
The lateral skirting board member 6 of the skirting board finishing material 4 contacts the stepping corresponding end surface 6a with the surface of the stepping finishing material 1 and the surface of a part of the upper plate portion 21 which is continuous with the stepping finishing material 1, and presses them down, while entering the corners. It is attached to the portion 91 (a part of the side wall foundation 9). When the trampling material 1 and the upper plate portion 21 have the same thickness, the step-corresponding end surface 6a of the horizontal skirting member 6 is brought into contact with the surface of the trampling material 1 and the surface of the upper plate portion 21 without a gap. You can
As described above, the vertical skirting board member 5 and the horizontal skirting board member 6 having the adhesive layers 52 and 62 on the back surface are bonded to the side wall base 9 through the adhesive layer 52 and 62.

The second joint end surface 5c of the vertical skirting member 5 and the second joint end surface 6c of the lateral skirting member 6 are in contact with each other and are joined in an inclined straight line shape in a side view. The first joint end surfaces 5b and 6b and/or the second joint end surfaces 5c and 6c may be bonded to each other with an adhesive or the like.
Note that reference numeral 92 indicates a wallpaper (finishing material for decorating the side wall base 9) attached to the side wall base 9.

The stair finishing structure B can be constructed as follows, for example.
The nosing finishing material 2 is attached to the nosing portion 82 of the stairs base 8 that has already been constructed. Next, the tread finishing material 1 is attached to the tread surface portion 81 of the stairs base 8 through the attaching means, and the rise finishing material 3 is attached to the rise surface portion 83 through the attaching means. It should be noted that the construction order of the nosing finish material 2, the step finish material 1, and the rise finish material 3 is not limited to the above order, and can be appropriately changed. Further, the nosing finish material 2, the step finish material 1 and the rise finish material 3 are applied with their longitudinal directions substantially parallel to the width direction of the stairs base 8.
Further, when the stepping finish material 1 is not provided with a pasting means in advance, after applying an adhesive or sticking a double-sided adhesive tape on the back surface of the stepping finish material 1 and/or the surface of the tread surface portion 81, It should be installed. The same applies to the case where the tacking finishing material 3 and the nosing finishing material 2 are not provided with pasting means in advance.
Next, the fitting recess 51 of the vertical skirting board member 5 is fitted into the nosing finish material 2, and the vertical skirting board member 5 is pressed in the direction of the nosing finish material 2 and the riser finishing material 3 while vertically using the attaching means. The skirting board member 5 is attached to the entry corner portion 91 (side wall foundation 9). While pressing the horizontal skirting board member 6 toward the rise finish material 3, the horizontal skirting board member 6 is attached to the entry corner portion 91 (side wall foundation 9) through the attaching means. At this time, the first joint end surface 6b of the horizontal skirting board member 6 contacts the first joint end surface 5b of the vertical skirting board member 5. The vertical skirting member 5 may be attached after the horizontal skirting member 6 is attached.
When the vertical skirting board member 5 is not provided with a pasting means in advance, an adhesive is applied or a double-sided adhesive tape is applied to the back surface of the vertical skirting board member 5 and/or the surface of the corresponding corner portion 91. It can be applied after pasting. The same applies to the case where the horizontal baseboard member 6 is not provided with a pasting means in advance.
When the surface of the stairs base 8 has slight irregularities, the step finish material 1, the rise finish material 3 and the nose finish material 2 may be attached after the smoothing process.

In the upper plate portion 21 of the nosing finishing material 2 in which the uneven surface including the convex portion 24 is formed, when the upper plate portion 21 in which the uneven surface is formed excluding both side portions 21x, 21x is used, The end face of the fitting recess 51 of the vertical skirting board member 5 and the step-corresponding end face 6a of the horizontal skirting board member 6 come into contact with the side portion without a gap. For this reason, the finished appearance is beautiful and it is difficult for dust to enter.
When the convex portion 24 is made of foamed resin, the convex portion 24 is appropriately compressed even if the convex portion 24 is formed in a region including both side portions 21x, 21x of the upper plate portion 21. The end faces of the fitting recess 51 of the vertical skirting member 5 and the step-corresponding end face 6a of the horizontal skirting member 6 come into contact with the side portions 21x, 21x without a gap.

Since the staircase finishing material A of the present invention has the stepping finish material 1, the nose finish material 2 and the skirting board finish material 4 (preferably, the rise finish material 3) for finishing one step of the staircase, It can be decorated and finished. The tread finishing material 1, the finishing finishing material 3, the nosing finishing material 2 and the skirting board finishing material 4 are formed in a shape suitable for the tread surface portion 81, the tread surface portion 83, the nose portion 82 and the entry corner portion 91, respectively. Therefore, these can be easily installed on the stairs base 8. In particular, when the back surface of these members is provided with a sticking means, it is not necessary to apply an adhesive or the like at the time of construction, and the construction can be performed very easily. According to the present invention, at the initial stage of the construction of a building such as a house, only the stair base 8 is installed, and the worker uses the stair base 8 as it is for raising and lowering without curing, and at the end of the construction, the stair finishing material A is used. It becomes possible to deliver it to the owner in a beautiful state after construction.
Since the staircase finishing material A of the present invention can be applied relatively easily, the staircase base 8 can be neatly finished not only by a carpenter, but also by an interior technician who is a construction specialist such as wallpaper. Therefore, in the building process of the building, first, the staircase foundation 8 is constructed to ensure the movement of the worker upstairs and downstairs, and after that, after finishing the interior such as wallpaper and fittings, or At the same time as finishing, the stairs can be finished by applying the stair finishing material A of the present invention to the stairs base 8.

The stair finishing structure B using the stair finishing material A of the present invention is attached to the side wall foundation 9 while the step-corresponding end surface 6a of the horizontal skirting member 6 holds the upper plate portion 21 of the nosing finishing material 2 and the step finishing material 1. Therefore, it is possible to suppress the upper plate portion 21 and the tread material 1 of the nosing finishing material 2 from rising from the tread surface portion 81 with time. Further, since the vertical skirting member 5 is attached to the side wall foundation 9 while pressing the front plate portion 22 of the nosing finish material 2, the front plate portion 22 of the nose finish material 2 is, in the course of time, the front surface of the nose portion 82. Can be suppressed from rising.
Since the upper plate portion 21 of the nose finishing material 2 covering the upper surface of the nosing portion 82, which is most loaded when using the stairs, is pressed by the vertical skirting member 5 and the horizontal skirting member 6, the nosing finishing material 2 Can be firmly fixed.
Further, since the stepping finishing material 1 is a separate body from the staircase foundation 8, when the stepping finishing material 1 is damaged during or after the construction, or when the stepping finishing material 1 is deteriorated over time, or the tread surface portion Only when changing the design, it is possible to easily reattach only the step finish material 1. That is, since the tread surface portion 81 of the stair base 8 can be left as it is and only the tread material 1 can be easily replaced, the stair can be repaired with a small cost and time. In particular, since the stepping finish material 1 provided with the suction portion 12 can be easily replaced, it is possible to realize the easy replacement which has never been achieved.

The design of the decorative layer 113 of the trampling material 1 may be the same as that of the corridor or the room floor adjacent to the stairs to increase the unity of the design and improve the design of the entire building. .. The same applies to the design of the rise finish material 3. Furthermore, since the conventional stairs for houses were final finished products, wood materials were often used. However, in the present invention, since the stepping finishing material 1 is a separate body from the stairs base 8, Can be freely set regardless of the design of the surface of the staircase base 8. Therefore, it becomes possible to select the material forming the staircase base 8 in consideration of workability, strength, cost, etc. without considering the design of the staircase, and the selection range of the material becomes large.

[Modification]
In the nosing finishing material 2 of the above embodiment, the upper plate portion 21 and the front plate portion 22 are connected to each other at a substantially right angle, but, for example, as shown in FIG. 11, the upper plate portion 21 and the front plate portion 22 are It may be connected in an acute angle. As the acute angle, for example, the interior angle formed by the back surface of the upper plate portion 21 and the back surface of the front plate portion 22 is 70 degrees or more and less than 90 degrees, and preferably 80 degrees to 88 degrees.
Further, in the nosing finishing material 2 of the above-described embodiment, the lower plate portion 23 and the front plate portion 22 are connected to each other at a substantially right angle, but, for example, as shown in FIG. 22 may be connected in an acute angle. As the acute angle, for example, an inner angle formed by the back surface of the lower plate portion 23 and the back surface of the front plate portion 22 is 70 degrees or more and less than 90 degrees, and preferably 80 degrees to 88 degrees.
The nosing finishing material 2 in which at least one of the upper plate portion 21 and the lower plate portion 23 is connected to the front plate portion 22 at an acute angle is fitted into the nosing portion 82 and attached, and then the upper plate portion 21. Since the lower plate portion 23 holds the nosing portion 82, it can be firmly attached to the nosing portion 82.
In particular, in the nosing finishing material 2, the lower plate portion 23 is preferably connected to the front plate portion 22 at an acute angle. Thereby, even if the dimension of the front plate portion 22 is larger than the thickness Z2 of the nose portion 82, it is possible to attach the nose finish material 2 without a gap between the end portion of the lower plate portion 23 and the lower surface of the nose portion 82. Therefore, the versatility of the nosing finishing material 2 is improved.

In the nose finish material 2 of the above-described embodiment, the lateral length of the upper plate portion 21 is substantially the same as the lateral length of the upper surface of the nose portion 82 (the longitudinal length of the upper surface). For example, as shown in FIG. 12, the lateral length of the upper plate portion 21 may be larger than the lateral length of the upper surface of the nose portion 82. In this nosing finish material 2, the length of the upper plate portion 21 is larger than the length of the lower plate portion 23 in a side view, as shown in FIG. FIG. 13 shows a staircase finishing structure B in which the nosing finishing material 2 according to this modification is attached to the nosing portion 82. In this case, since the upper plate portion 21 of the nosing finishing material 2 is attached from the upper surface of the nosing portion 82 to a part of the tread surface portion 81, the tread finishing material 1 is formed correspondingly with a slightly shorter lateral length. ing.

Further, the nosing finishing material 2 of the above-described embodiment has a substantially U-shape in a side view having the lower plate portion 23. However, for example, as shown in FIG. 14, the nosing finishing material 2 includes the front plate portion 22 and the upper plate portion 22. The plate portion 21 may have a substantially L shape in a side view. FIG. 15 shows a staircase finishing structure B in which the nosing finishing material 2 according to this modification is attached to the nosing portion 82. In this case, the lower surface of the nosing portion 82 is not covered with the nosing finishing material 2, but the lower surface of the nosing portion 82 is a portion that cannot be seen by the user, so that even if it is not decorated with the nosing finishing material 2, there is no particular problem. There is no. Further, since the nosing finishing material 2 can be attached only by covering the nosing finishing material 2 from above the nosing portion 82, the nosing finishing material 2 can be easily aligned and fixed at the time of construction.

In the staircase finishing structure B of the above-described embodiment, the rear end of the upper plate portion 21 of the nosing finishing material 2 and the front end of the stepping finishing material 1 are in contact with each other in a butted state. The rear end and the front end of the step finish material 1 may be joined by various joining means. By joining the nosing finishing material 2 and the stepping finishing material 1, it becomes more difficult for the nosing finishing material 2 to come off, and not only the safety is enhanced but also the strength of the staircase structure can be improved.
For example, FIG. 16 shows a staircase finishing structure B in which the rear end of the upper plate portion 21 of the nosing finishing material 2 and the front end of the stepping finishing material 1 are joined at a joining portion 71 made of a resin material. Examples of the resin material forming the joint portion 71 include a resin that adheres to both the upper plate portion 21 and the step finish material 1. Such a joint portion 71 can be formed, for example, by melting a welding rod made of a thermoplastic resin between the rear end portion of the upper plate portion 21 and the front end portion of the step finish material 1. A relatively strong joining force can be easily exhibited by using a welding rod. Further, in order to improve the appearance of the joint portion, a treatment liquid for seam joining may be used as the joining means instead of the welding rod. The joint joining treatment liquid is used by injecting it between the upper plate portion 21 and the abutting end of the step finish material 1, and the end portion can be joined by solidifying the treatment liquid.

17 and 18 show a staircase finishing structure B in which the rear end portion of the upper plate portion 21 of the nosing finishing material 2 and the front end portion of the stepping finishing material 1 are overlapped and joined to each other.
In FIG. 17, the front surface side of the rear end portion of the upper plate portion 21 of the nosing finishing material 2 is partially extended, and a downward step portion 73 is formed on the rear surface side of the extended portion 72. The surface of the front end 1a of the step finish material 1 is covered with the extending portion 72 of the upper plate portion 21, and the front end 1a of the step finish material 1 is housed in the downward step 73. If necessary, the front end portion 1a of the step finish material 1 and the extending portion 72 (or the downward step portion 73) may be bonded with an adhesive or the like. According to such a joint structure, the front end of the tread material 1 is hidden by the extending portion 72, so that the front end portion 1a of the tread material 1 is unlikely to peel off and the appearance is also good.
In FIG. 18, the rear surface side of the rear end portion of the upper plate portion 21 of the nosing finishing material 2 is partially extended, and the upward step portion 75 is formed on the front surface side of the extended portion 74. The front end portion 1a of the step finish material 1 is placed on the surface of the upward stepped portion 75, and the upper plate portion 21 and the step finish material 1 are joined. If necessary, the front end portion 1a of the step finish material 1 and the extending portion 74 (or the upward step portion 75) may be bonded with an adhesive or the like. According to this joint structure, since the step finish material 1 is attached after the nose finish material 2 is attached to the nose section 82, the step finish material 1 can be easily removed when the step finish material 1 is repaired.
Although not particularly shown, the end portions of the nosing finish material 2 and the rise finish material 3, and the rise finish material 3 and the step finish material 1 may also be joined in the same manner.

It is preferable that the extending portions 72 and 74 are formed to have a thickness smaller than that of the step finishing material 1. For example, the thickness of the step finish material 1 is usually about 1 mm to 5 mm, while the thickness of the extending portions 72, 74 is set to 0.1 mm to 0.5 mm, preferably 0.2 mm to 0.4 mm. To be done.
Further, it is preferable that the end portions (rear end portions) of the extending portions 72 and 74 are formed so as to have a smaller thickness than the other portions of the extending portions. For example, it is preferable to form an inclined surface such that the wall thickness decreases toward the end portion (rear end portion), as in the extending portion 72 shown in FIG. By forming the inclined surface, a step is less likely to occur between the surface of the stepping finish material 1 and the step. For example, the cross-sectional shape of the extending portion may be a substantially triangular shape or a beak shape.

The extension length of the extension parts 72 and 74 (the length of the extension part in the front-rear direction) is set to, for example, 5 mm to 50 mm. When the front end portion 1a of the stepping finishing material 1 covers all the extending portions 72, 74 having such an extending length, the covering length of the extending portions 72, 74 and the stepping finishing material 1 is 5 mm or more. It becomes 50 mm.
When the step finish material 1 and the extending portions 72, 74 are joined as described above, for example, adhesion using an adhesive or a pressure-sensitive adhesive, melt adhesion for pressure bonding while heating, solvent adhesion for melting and pressure bonding with a solvent, etc. Adhesion method can be mentioned. Adhesion with an adhesive is preferable from the viewpoint of workability and bonding strength. Further, the joint strength between the extending portions 72, 74 and the stepping finishing material 1 can be increased by reinforcing the contacting portions with a method such as sealing or taping.
Further, in the example of FIG. 17, the front end portion 1a of the step finish material 1 is cut off by an amount corresponding to the thickness of the extending portion 72, whereby the surface of the front end portion 1a of the step finish material 1 and the surface of the upper plate portion 21 are removed. It can be formed into a continuous flat shape. Further, as shown in FIG. 18, a method may be used in which the suction portion is not provided on the back surface of the front end portion 1a. By this method, the surface of the front end portion 1a of the step finish material 1 and the surface of the upper plate portion 21 can be formed into a continuous flat shape without reducing the thickness of the front end portion 1a of the step finish material 1.

Further, in the skirting board finishing material 4 of the above-described embodiment, the first joining end surface 6b and the second joining end surface 6c of the horizontal skirting board member 6 are joined in an inclined linear shape in a side view. As shown, the first joint end surface 5b and the second joint end surface 5c of the vertical skirting board member 5 and the first joint end surface 6b and the second joint end surface 6c of the lateral skirting board member 6 are cut from the end surfaces cut out in an L shape. It may be configured. Even in such a case, as shown in FIG. 19, the first joint end surface 5b of the vertical skirting board member 5 and the first joint end surface 6b of the horizontal skirting board member 6 and the second joint end surface 5c of the vertical skirting board member 5 and the lateral side. The second joint end surface 6c of the baseboard member 6 comes into contact with each other.
In addition, the first joint end faces 5b, 6b and the second joint end faces 5c, 6c of the vertical skirting member 5 and the horizontal skirting member 6 may be formed in such a shape that they are in contact with each other, and are not limited to the illustrated example. Not a thing. For example, as shown in FIG. 20, the first joint end surface 6b of the horizontal skirting board member 6 may be formed in a straight line shape in contact with the long side end surface of the vertical skirting board member 5. Further, as shown in the figure, the second joint end surface 5c of the vertical skirting board member 5 may be formed in a linear shape in contact with the long side end surface of the horizontal skirting board member 6.

In the above-described embodiment, the stepping material 1 having the suction portion 12 provided on the back surface is exemplified, but the stepping material 1 without the suction portion 12 may be used. The tread material 1 that does not have the adsorption portion 12 is attached to the tread surface portion 81 via an adhesive layer or an adhesive layer, but is preferably attached using a double-sided adhesive tape.
