Description

  The present invention relates to a corner material used by being attached to a corner portion of a building.

Conventionally, for the purpose of concealing joints at the corners of the building, the corner material is attached across the first structure surface and the second structure surface at the corners. Examples of the first structure surface and the second structure surface include a wall surface and a wall surface, a wall surface and a floor surface, or a wall surface and a ceiling surface that intersect at a substantially right angle.
As the corner material, there is known a corner member in which an outer plate and an inner plate having an L-shaped cross section are joined at both ends (Patent Document 1). In the corner member of Patent Document 1, since the L-shaped outer plate and inner plate are joined, a right-angled corner portion (a corner portion in which the first structure surface and the second structure surface form 90 degrees) ).
However, in the actual construction site, the corners are not necessarily a right angle and often have an angle slightly larger than 90 degrees (that is, an obtuse angle) or an angle that is slightly smaller (that is, an acute angle). Further, there may be a case where a right angle portion, an obtuse angle portion, and an acute angle portion are present randomly. For this reason, when the corner member is attached to an obtuse angled corner or an obtuse angled portion of the angled corner, a gap is generated between the inner plate and the wall surface of the corner member, while an acute angled corner or angled corner There is a problem that it is difficult to insert a corner member into an acute angle portion.

In addition, as disclosed in FIG. 3 of Patent Document 2 (the code in this section is a transcription of that of Patent Document 2), the corner material has a base material 3 extending in one direction, This base material 3 is located between the right thick part 3a located on one side, the left thick part 3b located on the other side, and the two thick parts 3a, 3b, and An edge member having an open groove 9 forming an arcuate surface 12 recessed in the thickness direction is known. The edge member is bent at a right angle so that the opening width of the opening groove 9 is widened, and the right thick portion 3a of the base material 3 is attached to one wall surface and the left thick portion 3b is attached to the other wall surface. Attach to the corner. According to the rim material of Patent Document 2, even if the corner of the corner forms an obtuse angle or an acute angle, the thick portion can be made to follow the wall surface by appropriately adjusting the bending angle.
However, the edge material of Patent Document 2 is provided with an opening groove 9 that forms an arcuate surface 12, and the edge material is bent and attached to the corners so that the cavity formed by the opening groove 9 expands. The area of the affixed portion is reduced and mounting stability is lacking. Further, since the opening groove 9 of the edge member is greatly opened at the time of bending, the distance between the bent portion of the edge member and the entering corner portion becomes large, and positioning of the edge member with respect to the entering corner portion becomes difficult. In addition, since the bent portion of the rim material is thin, it is difficult to increase the strength after construction.
Especially in corners where water resistance is required, such as bathrooms, kitchens, washrooms, toilets, etc., a part that is attached to the wall to prevent gaps from entering when corners are installed It is required to satisfy both securing the area and improving the positioning accuracy.

[First Embodiment]
The corner material of the present invention is a building member that is attached across the first structure surface and the second structure surface in the corner portion of the building.
In FIG.1 and FIG.2, the corner material 10 is the elongate shape extended in one direction as a whole. The long shape means a shape in which the length in one direction is sufficiently longer than the length in the other direction (a direction orthogonal to the one direction). The long corner material 10 has a length in one direction of, for example, 50 cm or more, and preferably 100 cm or more. The long corner material 10 is used after being cut to an appropriate length during construction.
The corner material 10 includes an outer wall 3, a first affixing wall 1 that is affixed to the first structure surface of the corner of the building, and a second affixing wall 2 that is affixed to the second structure surface of the corner. A support leg 4 is provided inside the main body. Grooves 51 and 52 are provided between the tip 11 of the first sticking wall 1 and the support leg 4 and between the tip 12 of the second sticking wall 2 and the support leg 4, respectively.
In addition, since the corner member 10 has a long shape extending in one direction, the outer wall 3, the first application wall 1, the second application wall 2, the support leg 4, and the grooves 51 and 52 are also in one direction. It extends. Accordingly, the corner material 10 has the same cross-sectional shape even when cut at any location in the longitudinal direction, and the cross-sectional shape is the same as the planar shape shown in FIG.

The main body is made of a flexible material. Here, the flexibility refers to a property that is flexible enough to be easily bent by an operator's human power. Since the main body is flexible, the main body can be bent in the direction of the arrow X or Y in FIG. Even if processing, such as a process, is not performed, the corner material 10 can be attached in close contact with the corner portion. Preferably, the main body has elasticity that returns to its original state when the force is released after bending in the direction of the arrow X or Y. Since the main body has such elasticity, the shape in the direction of the arrow X or Y is stabilized, so that the work of bonding the corner material 10 to the corner portion becomes easy.
For example, the hardness of the main body is 40 to 90, preferably 45 to 85, and more preferably 50 to 80. If the hardness is too small, it becomes difficult to handle the corner material 10, and if the hardness is too large, the corner material 10 may be difficult to deform according to the angle of the corner portion. However, the hardness refers to a value measured by durometer type A according to JIS K 6253.

The second sticking wall 2 extends from the second side end portion 32 of the outer wall 3 and extends at an acute angle with respect to the outer wall 3.
Although the 1st sticking wall 1 and the 2nd sticking wall 2 are extended so that the front-end | tip parts 11 and 21 may face each other, the front-end | tip part 11 of the 1st sticking wall 1 and the front-end | tip part 21 of the 2nd sticking wall 2 Has been separated. A support leg 4 is provided between the distal end portion 11 of the first pasting wall 1 and the distal end portion 21 of the second pasting wall 2 with grooves 51 and 52 interposed therebetween.
Specifically, the surface of the outer wall 3 is a circular arc surface recessed inward. Although the width W3 of the outer wall 3 is not specifically limited, For example, it is 8-30 mm, Preferably, it is 10-25 mm. The width W3 of the outer wall 3 is a straight length connecting the first side end 31 and the second side end 32 of the outer wall 3 as seen in the plan view of FIG. In the present embodiment in which a first convex portion 71 and a second convex portion 72 (details of which will be described later) are projected from the surfaces of the first adhesive wall 1 and the second adhesive wall 2, The first side end portion 31 of the outer wall 3 is a portion where the surface of the outer wall 3 and the virtual extension surface of the first sticking wall 1 intersect, and the second side end portion 32 of the outer wall 3 This corresponds to a portion where the virtual extension surface of the sticking wall 2 intersects.

  The base end portion of the first sticking wall 1 is integrated with the first side end portion 31 of the outer wall 3. The 1st sticking wall 1 is extended from the said 1st side edge part 31 so that the surface may form an acute angle with respect to the surface of the outer wall 3. As shown in FIG. The distal end portion 11 of the first sticking wall 1 that is an extended end is a free end portion independent of the support leg 4. The base end portion of the second sticking wall 2 is integrated with the second side end portion 32 of the outer wall 3. The 2nd sticking wall 2 is extended from the 2nd side edge part 32 so that the surface may form an acute angle with respect to the surface of the outer wall 3. As shown in FIG. The distal end portion 21 of the second sticking wall 2 that is an extended end is a free end portion independent of the support leg 4. The acute angle means that the angle formed by the surface of the first sticking wall 1 or the surface of the second sticking wall 2 and the surface of the outer wall 3 is an acute angle. In addition, when the surface of the outer wall 3 is an arc surface as in the present embodiment, the surface of the outer wall 3 serving as the reference for the acute angle includes the first side end 31 and the second side end 32 of the outer wall 3. It shall mean the plane containing. The acute angle is preferably 40 ° to 50 °, more preferably 42.5 ° to 47.5 °, and particularly preferably about 45 °.

  The surface of the first sticking wall 1 and the surface of the second sticking wall 2 are both flat. The first affixing wall 1 and the second affixing wall 2 are provided such that an angle α formed by the virtual extension surface of the first affixation wall 1 and the virtual extension surface of the second affixation wall 2 is 80 degrees to 100 degrees. ing. Preferably, the angle α formed by the virtual extension surface of the first sticking wall 1 and the virtual extension face of the second sticking wall 2 is 85 ° to 95 °, more preferably approximately 90 °. A first affixing wall 1 and a second affixing wall 2 are provided. The virtual extension surface of the first sticking wall 1 means a plane including the surface of the first sticking wall 1, and the virtual extension surface of the second sticking wall 2 means a plane including the surface of the second sticking wall 2.

  A groove 51 (hereinafter referred to as a first groove) is provided between the distal end portion 11 of the first sticking wall 1 and the support leg 4, and the tip portion 21 of the second sticking wall 2 and the support leg 4 are supported. A groove 52 (hereinafter referred to as a second groove) is provided between the leg 4 and the leg 4. The first groove 51 and the second groove 52 extend in the direction of the outer wall 3. The first groove 51 is formed by two opposing inner wall surfaces 51 a and 51 b extending in the direction of the outer wall 3. In the present embodiment, the two inner wall surfaces 51 a and 51 b are formed so as to approach each other toward the outer wall 3. The second groove 52 is formed by two opposing inner wall surfaces 52 a and 52 b extending in the direction of the outer wall 3. In the present embodiment, the two inner wall surfaces 52 a and 52 b are formed so as to approach each other toward the outer wall 3. The inner wall surface 51 b and the inner wall surface 52 b are also wall surfaces that form the shaft portion 41. By providing the first groove 51 and the second groove 52, the main body is easily bent, and therefore, the work of attaching the corner material 10 in close contact along the corner is facilitated. In addition, since the first groove 51 and the second groove 52 are arranged on the left and right sides of the main body, the main body can be bent independently on the left and right sides of the main body. The corner member 10 can be attached satisfactorily.

  The opening widths W51 and W52 of the first groove 51 and the second groove 52 are not particularly limited, but are independently, for example, 1 mm to 5 mm, and preferably 2 mm to 4 mm. If the opening widths W51, W52 of the grooves 51, 52 are too small, it is difficult to bend the corner material 10. On the other hand, if the opening widths W51, 52 of the grooves 51, 52 are too large, the first affixing wall 1 is relatively. And the area of the 2nd sticking wall 2 becomes small, and there exists a possibility that the attachment stability of the corner material 10 may worsen. However, the opening width W51 of the first groove 51 is the length between the tip 11 of the first sticking wall 1 and the end of the first surface 421 of the support leg 4, and the opening of the second groove 52 is The width W <b> 52 is a length between the distal end portion 21 of the second sticking wall 2 and the end portion of the second surface 422 of the support leg 4.

The support leg 4 is disposed between the front end portions 11 and 21 of the first sticking wall 1 and the second sticking wall 2 facing each other, and protrudes from the center of the main body to the opposite side of the surface of the outer wall 3.
The support leg 4 includes a shaft portion 41 connected to the main body and a grounding portion 42 provided at the tip of the shaft portion 41. The shaft portion 41 of the support leg 4 is arranged corresponding to the center portion in the width direction of the outer wall 3 and extends so as to be substantially orthogonal to the surface of the outer wall 3. Preferably, the shaft portion 41 is provided so that the axis L of the shaft portion 41 coincides with the center point in the width direction of the outer wall 3. The grounding portion 42 is wider than the shaft portion 41 and is formed in a substantially trapezoidal shape in plan view. The surface of the grounding portion 42 includes a first surface 421 that exists on the virtual extension surface of the first pasting wall 1, a second surface 422 that exists on the virtual extension surface of the second pasting wall 2, and the first surface 421. A third surface 423 that exists between the second surfaces 422 and forms an obtuse angle with respect to both surfaces 421 and 422. The first surface 421, the second surface 422, and the third surface 423 are flat. The support leg 4 can make the first surface 421 and the second surface 422 abut on the corner when attaching the corner 10 to the corner, and the positioning of the corner 10 is more accurate. Can be performed.

The width W42 of the ground contact portion 42 of the support leg 4 is not particularly limited, but is, for example, 1 mm to 3 mm, and preferably 1.5 mm to 2.5 mm. If the width W42 of the grounding portion 42 is too small, the grounding portion 42 may be deformed and the mounting position of the cornering material 10 may be shifted when the corner material 10 is pressed against the corner portion during construction, If the width W42 of the ground contact portion 42 is too large, the areas of the first and second application walls 1 and 2 are relatively small, and the attachment stability of the corner material 10 may be deteriorated.
The width W41 of the shaft portion 41 of the support leg 4 is not particularly limited, but is, for example, 0.8 mm to 3 mm, and preferably 1 mm to 2.5 mm. If the width W41 of the shaft portion 41 is too small, the shaft portion 41 may be bent when the corner material 10 is pressed against the corner portion during construction, and the mounting position of the corner material 10 may be shifted. If the width W41 of the portion 41 is too large, the grooves 51 and 52 are relatively narrow, and the corner material 10 may be difficult to bend. However, the width W42 of the grounding portion 42 and the width W41 of the shaft portion 41 are widths when the grounding portion 42 and the shaft portion 41 are viewed from the axial direction of the shaft portion 41. In the illustrated example, the width W42 of the grounding portion 42 and the width W41 of the shaft portion 41 are equal in the axial direction. However, the grounding portion 42 and the shaft portion 41 may have portions having different widths in the axial direction, and the width W42 and the width W41 of the grounding portion 42 and the shaft portion 41 having such a portion are: It shall mean the smallest width.

  Furthermore, the 1st convex part 71 which protrudes from the surface of the 1st sticking wall 1 is formed in the base end part of the said 1st sticking wall 1. As shown in FIG. Further, a second convex portion 72 that protrudes from the surface of the second pasting wall 2 is formed at the proximal end portion of the second pasting wall 2. By providing the 1st convex part 71 and the 2nd convex part 72, the adhesive agent was apply | coated to the 1st sticking wall 1 and the 2nd sticking wall 2, or the adhesive tape was affixed, and the corner material 10 was attached to the corner area. In this case, the gap between the first side end portion 31 of the outer wall 3 and the first structural surface and the gap between the second side end portion 32 of the outer wall 3 and the second structural surface can be closed. Therefore, the 1st convex part 71 and the 2nd convex part 72 have the effect of concealing the edge part of an adhesive agent or an adhesive tape, and improving the aesthetics after construction.

The first convex portion 71 has a first side extending at an obtuse angle with respect to the surface of the first sticking wall 1 and an extended surface of the surface of the first sticking wall 1 from the first side end portion 31 of the outer wall 3. On the other hand, it is a substantially triangular portion formed from a second side extending in an arc shape while being substantially orthogonal. The top of the first convex portion 71 is a portion where the first side and the second side are joined. Similarly, the second protrusion 72 has a first side extending at an obtuse angle with respect to the surface of the second sticking wall 2, and a surface of the second sticking wall 2 from the second side end 32 of the outer wall 3. A substantially triangular portion formed from a second side extending in an arc shape while being substantially orthogonal to the extended surface. The top portion of the second convex portion 72 is a portion where the first side and the second side are joined. The tops of the first convex portion 71 and the second convex portion 72 may have an arc shape, but an angular shape is preferable, and it is more preferable that the first convex portion 71 and the second convex portion 72 have a sharp acute angle as shown in the illustrated example. By making these apexes angular, the first convex portion 71 and the second convex portion 72 can easily follow the first structural surface and the second structural surface, and conceal the ends of the adhesive and the adhesive tape. Becomes higher. In particular, by making these apexes sharp and sharp, high concealability can be ensured even if the area ratio of the convex portions 71 and 72 to the pasting walls 1 and 2 is relatively small, and the first pasting wall 1 and The adhesion area of the 2nd sticking wall 2 can be enlarged relatively.
The projecting heights H71 and H72 of the first convex portion 71 and the second convex portion 72 are not particularly limited, but are independently, for example, 0.1 mm to 2 mm, and preferably 0.3 mm to 1. 5 mm. If the protruding heights H71 and H72 of the first convex portion 71 and the second convex portion 72 are too small, an adhesive or an adhesive is used when the corner material 10 is attached to the corner portion using an adhesive or an adhesive tape. There exists a possibility that the effect | action which conceals the edge part of a tape may fall. On the other hand, if each protrusion height H71, H72 of the 1st convex part 71 and the 2nd convex part 72 is too large, when attaching the corner material 10 to a corner part, the 1st sticking wall 1 and the 2nd sticking wall 2 will be. There is a possibility that it is difficult to adhere to the first structure surface and the second structure surface.
In the illustrated example, the shape of the corner material 10 is symmetrical at the center in the width direction.

Since the corner member 10 having the above configuration is flexible and has grooves 51 and 52, as shown by an arrow X in FIG. 2, the proximal end portion of the first sticking wall 1 and the second sticking wall 2. Bend the first affixing wall 1 and the second affixing wall 2 so that the proximal end of the outer wall 3 comes to the surface side of the outer wall 3, and the proximal end of the first affixing wall 1 as indicated by the arrow Y in FIG. And the 1st sticking wall 1 and the 2nd sticking wall 2 can be bent so that the base end part of the 2nd sticking wall 2 may come out on the opposite side to the surface of the outer wall 3. When the first sticking wall 1 and the second sticking wall 2 are bent in the direction of the arrow X, the angle α formed by the virtual extension surface of the first sticking wall 1 and the virtual extension surface of the second sticking wall 2 becomes small. The surface of the 1st sticking wall 1 and the surface of the 2nd sticking wall 2 can be made to go along the corner which comprises. If the first sticking wall 1 and the second sticking wall 2 are bent in the direction of the arrow Y, the angle α formed by the virtual extension surface of the first sticking wall 1 and the virtual extension surface of the second sticking wall 2 becomes large. The surface of the 1st sticking wall 1 and the surface of the 2nd sticking wall 2 can be made to go along the corner which comprises.
Furthermore, even in a corner where a right angle portion, an acute angle portion, and an obtuse angle portion are randomly present, the corner material 10 is partially bent appropriately in the arrow X direction or the arrow Y direction. Therefore, it is possible to place the corner material 10 along the entire corner without a gap.

The corner material 10 of the present invention is used by being attached to a corner portion of a building.
Specifically, the corner material 10 is attached across the first structure surface and the second structure surface in the corner portion of the building. Examples of the first structure surface and the second structure surface include a wall surface and a wall surface, a wall surface and a floor surface, or a wall surface and a ceiling surface that intersect at a substantially right angle. In the corner material 10 of the present invention, the first affixing wall 1 and the second affixing wall 2 are in close contact with each other along the first structure surface and the second structure surface, and has excellent sealing performance with respect to the corner of the corner. Suitable for corners that require waterproofing, such as bathrooms, kitchens, washrooms, toilets, etc., because the support legs 4 can ensure accurate alignment and high adhesion, as well as being able to fit along the entire corner. Can be used. In particular, the corner material 10 of the present invention can be used very suitably for the corner of a bathroom where high waterproofness is required.
The corner member 10 is formed by sticking the first sticking wall 1 to the first structure surface and sticking the second sticking wall 2 to the second structure surface while the support leg 4 is applied to the corner portion of the corner. Can be attached to the corner.
The method of attaching the first sticking wall 1 and the second sticking wall 2 to each structural surface is not particularly limited, but typically, bonding using an adhesive or an adhesive tape or both an adhesive and an adhesive tape is performed. Can be mentioned.

FIG. 3 is a reference plan view showing the main part of the building in which the corner material 10 is attached to the corner portion 9 using the adhesive tape 98. In FIG. 3, the hatched portion indicates the adhesive tape 98.
In FIG. 3, the corner 9 is composed of, for example, two wall surfaces 91 and 92 that intersect at a substantially right angle at the corner 93. On the wall surfaces 91 and 92, cover materials 94 and 95 such as a decorative sheet material, wallpaper, and a decorative board may be attached as necessary. As shown in the figure, when the surface material 94 is affixed to the wall surface 91, the surface of the surface material 94 corresponds to the first structure surface, and when the surface material 95 is affixed to the wall surface 92, The surface of the material 95 corresponds to the second structure surface, and the intersection of the surface of the surface covering material 94 and the surface of the surface covering material 95 corresponds to a corner.
An adhesive tape 98 provided with an adhesive on both sides is attached to the surface of the first sticking wall 1 of the corner 10 and the first surface 421 of the support leg 4. The affixing wall 1 and the support leg 4 are bonded to the first structural surface. Similarly, an adhesive tape 98 provided with an adhesive on both sides is attached to the surface of the second sticking wall 2 of the corner member 10 and the second surface 422 of the support leg 4. The second sticking wall 2 and the supporting leg 4 are bonded to the second structural surface. When the protruding heights of the first convex portion 71 and the second convex portion 72 are larger than the thickness of the adhesive tape 98, the first convex portion 71 and the second convex portion 72 are the first structural surface and the second structural surface. The first structure surface and the second structure surface are in close contact with each other while being pressed. For this reason, a gap does not occur between the first side end 31 of the outer wall 3 and the first structural surface and between the second side end 32 of the outer wall 3 and the second structural surface, and the corner material 10 is used. Thus, the corner 9 can be sealed well. At this time, when the first convex portion 71 and the second convex portion 72 have an angular shape, the first convex portion 71 and the second convex portion 72 are more likely to be deformed by pressing toward the top, so that the first convex portion 71 and the second convex portion 72 are the first structural surface. And it comes to contact | adhere to the 2nd structure surface reliably. For this reason, even when the protruding heights of the first convex portion 71 and the second convex portion 72 are larger than the thickness of the adhesive tape 98, the first convex portion 71 and the second convex portion are formed on the first structural surface and the second structural surface. The convex part 72 can be stuck closely.

By the way, the corner 9 is not necessarily a right angle, and an angle formed by the first structure surface and the second structure surface is greater than 90 degrees (for example, an obtuse angle greater than 90 degrees and less than 95 degrees) or There may be a small angle (for example, an acute angle of 85 degrees or more and less than 90 degrees). Such an obtuse or acute angle portion may extend over the entire longitudinal direction of the corner, or may exist in a portion of the corner of the corner.
In this regard, in the corner member 10 of the present invention, the tip portions 11 and 21 of the first and second sticking walls 1 and 2 are independent, and grooves 51 and 52 are formed between the support leg 4 and the corners 10 and 21, respectively. Therefore, as described above, the corner material 10 can be easily bent in the arrow X direction and the arrow Y direction. For this reason, the corner material 10 can be affixed along the first affixing wall 1 and the second affixing wall 2 also to the corner 9 having an acute angle or an obtuse angle.

Furthermore, since the support leg 4 is protrudingly provided between the 1st sticking wall 1 and the 2nd sticking wall 2, the positioning of the corner material 10 with respect to a corner corner can also be performed easily. Specifically, when the corner member is aligned and attached so that the center portion of the outer wall faces the corner portion of the corner corner, the corner corner material is not biased in any direction in the width direction. Appearance after construction of the material is improved. However, the flexible corner material may be deformed when pressed against the corner portion, and may be displaced. In this respect, the corner member 10 according to the present invention is provided with the support legs 4 projecting on the opposite side to the surface of the outer wall 3, so that the surface of the outer wall 3 is applied to the corners of the corner of the corner. The corner material 10 can be positioned by pressing toward the corner. In particular, since the shaft portion 4 extends so as to be substantially orthogonal to the surface of the outer wall 3, the support leg 4 is not easily bent when the surface of the outer wall 3 is pressed toward the corner portion of the entrance corner, and the positioning is performed. Can be done reliably.
The corner material 10 of the present invention that can be easily attached to the first structure surface and the second structure surface of the first application wall 1 and the second application wall 2 by bending and can be positioned easily is not an expert. However, it can be stably attached to the corner.

Moreover, since the area of the 1st sticking wall 1 and the 2nd sticking wall 2 is comparatively large, the corner material 10 of this invention has a large sticking area with respect to a corner corner. In particular, since the corner material 10 can also apply an adhesive tape to the first surface 421 and the second surface 422 of the support leg 4, it is also possible to increase the application area.
Furthermore, since the support leg 4 exists between the outer wall 3 of the corner 10 and the corner of the corner, the corner 10 is difficult to be dented or bent after the construction, and the construction structure is stronger. It becomes.
Thus, the corner material 10 of the present invention can be easily and stably attached to the corner portion, and can maintain high strength after construction.

FIG. 4 is a reference plan view showing a main part of a building in which the corner material 10 is attached to the corner portion using the adhesive 99. In FIG. 4, the portions with innumerable dots indicate the adhesive 99.
Even when the corner material 10 is pasted using the adhesive 99, the first convex portion 71 and the second convex portion 72 are deformed so that the gap is not generated, as in the case of pasting with the adhesive tape 98. Moreover, the corner material 10 can be easily and stably attached to the corner portion 9. Furthermore, when the corner material 10 is attached using the adhesive 99, the adhesive 99 enters the grooves 51 and 52 as shown in FIG. The corner member 10 can be firmly fixed to the corner portion 9. In particular, in the present embodiment, the first surface 421 of the support leg 4 is configured to protrude into the first groove 51 and the second surface 422 into the second groove 52, respectively. The two grooves 52 have a structure in which the inside is wider than the opening width. With this structure, when the adhesive flowing into the first groove 51 and the second groove 52 is solidified, a higher anchor effect is exhibited.

  The corner material of the present invention is not limited to the first embodiment, and can be variously modified within the range intended by the present invention. Hereinafter, although other embodiment of this invention is described, description is abbreviate | omitted about the structure, effect, and usage method similar to the said 1st Embodiment, and a term and a code | symbol are used as it is.

[Second Embodiment]
In the first embodiment, the grounding portion 42 of the support leg 4 is formed in a substantially trapezoidal shape in plan view. However, the present invention is not limited to this, and for example, as shown in FIG. It may be formed in a shape or an elliptical shape. When the ground contact portion 42 is formed in a curved surface in this way, it is possible to have a contact point on any of the curved surfaces of the support leg 4 with respect to an irregular corner portion. The corner member 10 can be easily positioned.
Moreover, as shown in FIG. 6, the grounding part 42 may be formed in a substantially rectangular shape that is horizontally long in a plan view. The horizontally long substantially rectangular shape is a substantially rectangular shape having a long direction orthogonal to the axis of the shaft portion 41. By making the grounding portion 42 in the shape as described above, the anchor effect in the case of fixing using an adhesive is increased, and the corner member 10 can be fixed more firmly.
Furthermore, in the said 1st Embodiment, although the grounding part 42 of the support leg 4 is formed wider than the axial part 41, it is not limited to this, For example, as shown in FIG. The ground portion 42 may be formed to be the same width as the shaft portion 41, or the grounding portion 42 may be formed to be narrower than the shaft portion, although not particularly illustrated. By making the shaft portion 41 in the shape as described above, the adhesive easily flows into the grooves 51 and 52, so that a highly viscous adhesive can also be used. In the example shown in FIG. 7, since the grounding portion 42 is formed in a curved surface shape, as in FIG. 5, the positioning of the corner material 10 with respect to the irregular corner corner is facilitated.

[Third Embodiment]
In the first embodiment, the support leg 4 is formed integrally with the main body. However, for example, as shown in FIG. 8, the support leg 4 may be formed of a member separate from the main body. The means for fixing the separate support leg 4 to the main body is not particularly limited. For example, as shown in the figure, a flange 41a is formed at the tip of the shaft part 41 of the support leg 4 and opposite to the surface of the outer wall 3 For example, the fitting recess 3a is formed in the main body on the side, and the support legs 4 are fixed to the main body by fitting both the concave and convex portions. In addition, although not shown, the support leg 4 may be bonded to the main body using an adhesive in combination with the uneven fitting or alone.
When the support leg 4 is formed of a separate member, the support leg 4 may be formed of a material having the same degree of flexibility as that of the main body. It is preferable that it is formed from the material which does not have flexibility. Examples of the material having small flexibility or substantially non-flexible material include metals and resins having high hardness. By using the support legs 4 having little flexibility or not having flexibility, it becomes easy to maintain the linearity in the longitudinal direction of the corner material 10 and the positioning accuracy with respect to the corner portion is improved. In addition, when the corner member 10 is pressed toward the corner portion of the corner portion, the shaft portion 41 of the support leg 4 becomes difficult to bend, and the corner member 10 can be positioned reliably.

[Fourth Embodiment]

May be. Moreover, as shown in FIG. 10, the surface of the outer wall 3 may be a flat surface. The shape of the surface of the outer wall 3 is not limited to the configuration shown in each embodiment, and can be changed to an appropriate shape in consideration of, for example, the design of the corners.

[Fifth Embodiment]
In the said 1st Embodiment, the 1st convex part 71 and the 2nd convex part 72 are substantially orthogonal to the 1st edge | side extended at an obtuse angle with respect to the surface of the 1st sticking wall 1 and the 2nd sticking wall 2. For example, as shown in FIG. 11, the first convex portion 71 and the second convex portion 72 are formed with respect to the surfaces of the first sticking wall 1 and the second sticking wall 2. It may protrude while forming an acute angle. In this case, each top part of the 1st convex part 71 and the 2nd convex part 72 protrudes toward the inner side. According to the corner material 10 of the present embodiment, one side edge of the adhesive tape can be inserted into the C-shaped pockets 711 and 721 formed by the first convex portion 71 and the second convex portion 72. The effect of concealing the end of the adhesive tape can be enhanced.
Moreover, as shown in FIG. 12, the corner material 10 of the present invention is not formed with the first and second convex portions, and the first and second adhesive walls 1 and 2 are formed in a flat shape. May be. Since the corner material 10 has a relatively simple shape, it can be manufactured more easily, and the manufacturing cost can be reduced. Moreover, as shown in FIG. 12, the 1st sticking wall 1 and the 2nd sticking wall 2 so that the angle which the virtual extension surface of the 1st sticking wall 1 and the virtual extension face of the 2nd sticking wall 2 make becomes an obtuse angle. May be formed. Thus, by forming the 1st wall surface 1 and the 2nd wall surface 2, the edge part of an adhesive tape can be concealed easily.

[Sixth Embodiment]
In the first embodiment, the first groove 51 and the second groove 52 are formed by the two inner wall surfaces 51a, 51b, 52a, and 52b that approach each other toward the outer wall 3, but are not limited to this. For example, As shown in FIG. 13, the first groove 51 may be formed from two parallel inner wall surfaces 51a and 51b, and the second groove 52 may be formed from two parallel inner wall surfaces 52a and 52b. Alternatively, as shown in FIG. 14, the first groove 51 is formed from two inner wall surfaces 51 a and 51 b that move away toward the outer wall 3, and the two inner wall surfaces 52 a and the second groove 52 that move away toward the outer wall 3. 52b may be formed. By forming the inner wall surfaces 51a, 51b, 52a, 52b so as to be parallel or away from each other toward the outer wall 3 in this way, the adhesive easily enters the first groove 51 and the second groove 52, so that the viscosity is particularly high. This is effective when an adhesive is used.
Furthermore, as shown in FIG. 13, the bottom wall surface 51 c of the first groove 51 and the bottom wall surface 52 c of the second groove 52 may be formed in an arcuate surface shape that swells to the surface side of the outer wall 3. As shown in FIG. 15, the bottom wall surface 51 c of the first groove 51 and the bottom wall surface 52 c of the second groove 52 may have a circular arc shape that swells on the opposite side to the surface of the outer wall 3. Thus, by making bottom wall surface 51c, 52c circular arc shape, the 1st groove | channel 51 and the 2nd groove | channel 52 become a stable shape, and the intensity | strength with respect to a bending becomes high.

[Seventh Embodiment]
In the said 1st Embodiment, although the one groove | channel 51 is formed in the 1st sticking wall 1 side and the one groove | channel 52 is formed in the 2nd sticking wall 2 side, it is not limited to this, The 1st A plurality of grooves may be formed on the affixing wall 1 side, and a plurality of grooves may be formed on the second affixing wall 2 side. For example, in the example shown in FIG. 16, two grooves 53 and 54 are formed on the first sticking wall 1 side, and two grooves 55 and 56 are formed on the second sticking wall 2 side. By forming a plurality of grooves in this way, it becomes easy to bend the corner material 10 in the direction of the arrow X and the direction of the arrow Y, and the angle α formed by the first and second application walls 1 and 2 is made acute or obtuse. Thus, it is possible to provide a corner material 10 that can be easily installed in various corners. Furthermore, when the corner material 10 is fixed using an adhesive, each of the plurality of grooves has an anchor effect, so that the corner material 10 can be more firmly fixed. In addition, even when a large amount of adhesive is applied, the adhesive enters the plurality of grooves, so that the adhesive protrudes from the first side end 31 or the second side end 32 of the corner member 10 to the outside. Can be suppressed. However, if the number of grooves is increased too much, the areas of the first sticking wall 1 and the second sticking wall 2 are relatively reduced, so that the grooves are on the first sticking wall 1 side and the second sticking wall 2 side, respectively. On the other hand, it is preferable to form one or two.
