Description

The present invention relates to a parting material and a method of attaching a parting material provided at a joint (parting part) between a corner of a wall and a ceiling (floor) in an interior work of a building structure such as a wall, ceiling or floor finishing work. ..

Generally, when finishing the walls and ceilings of building structures such as cloth and paint, the method of finishing the seams (parting parts) between the finished surface of the wall and the finished surface of the ceiling is mainly the peripheral method or abutment. A method, a parting material method, etc. are used.
The rim method is a method of attaching a long rim made of wood etc. to the parting part, and the abutting method is to use members such as the rim by abutting the finished surface of the wall and the finished surface of the ceiling. It is a method of construction without. The parting material method is a method in which a parting material is attached and used in order to beautifully fit the seam between the finished surface of the wall and the finished surface of the ceiling or floor.
Further, as for the method of finishing the joint (parting portion) between the finished surface of the wall and the finished surface of the floor, the method of using the baseboard, which is a long horizontal plate, for the parting portion is mainly used.
However, when finishing the parting part between the wall and the ceiling, the peripheral edge method is not suitable for a narrow space because the peripheral edge is conspicuous, and the abutting method is difficult to construct so as not to provide a gap in the parting part. For this reason, it has become common to use a parting material method that can simply finish the parting part and can be easily constructed.
Further, in the method of finishing the parting portion of the wall and the floor, attention is being paid to the parting material method which can be easily constructed in the same way as the parting portion of the wall and the ceiling.

Various types of such parting materials have been proposed.
Patent Document 1 relates to a non-combustible base material and an interior decorative structure of a protruding corner, and the non-combustible base material 30 includes a first sleeve plate portion 31 having a wall thickness corresponding to the thickness of the ceiling material and a first sleeve. A second sleeve plate portion 32, which is thinner than the plate portion 31, is provided, is arranged at the parting portion of the ceiling material, and is screwed to the field edge.
Patent Documents 2 and 3 relate to a parting edge material for interior use, and attach the parting edge material which is long and rectangular in a plan view to the parting portion.

(First Embodiment)
FIG. 1 is a schematic view when the parting material of the first embodiment of the present invention is applied to a joint (parting part) between a corner portion of a wall and a ceiling, and FIG. 2 is a schematic view of the case where the parting material of the first embodiment is applied. It is a perspective view which shows the parting material. FIG. 3 is a plan view of the parting material of the first embodiment, and FIG. 4 is a side view of the parting material of the first embodiment.

The parting material 10 of the present embodiment is attached to a joint (parting part) between a corner of a wall and a ceiling (floor) in an interior work of a building structure such as a wall, ceiling or floor finishing work, and has an arc shape. It is a member that can cover the gap between the corner of the wall and the ceiling (floor) and reinforce the periphery of the gap. It is provided with a parting material main body 5 having a pair of protective portions 2 and 2 provided continuously and attached to the wall, and a pair of mounting portions 3 and 3 provided at both ends of the parting material main body 5 ( 2, FIG. 3, and FIG. 4).

The parting material main body 5 is a member for covering the gap between the corner M of the arc-shaped wall and the ceiling (floor) to complement and protect the gap, and has an L-shape as a whole and is a wall. It is attached to the parting portion so that the upper surface of the corner M is in close contact with the ceiling (floor).
The parting material main body 5 is formed so that the protective portion 1 having a sufficient width 1d for covering the gap and the protective portion 1 are continuously provided at both ends of the protective portion 1 and smaller than the width 1d of the protective portion 1 (width 2d). It is composed of a pair of protection portions both ends 2 and 2, and a pair of attachment portions 3 and 3 for attaching other parting materials are provided at the other ends of the protection portions both ends 2 and 2.
Since the parting material main body 5 is closely attached to the corner portion M of the arc-shaped wall, the central position of the inner side surface 10a on the side to be attached to the corner portion M of the wall is formed in an arc-shaped cross section.
The radius of curvature at the center position of the inner side surface 10a is formed in the range of 10 mm to 15 mm. This means that in a building structure, when the corner M of the wall has an arcuate cross section (when the corner M of the wall has a curved surface), the radius of curvature of the corner M of the wall is in the range of 10 mm to 15 mm. caused by. Several types of parting materials having different radii of curvature of the inner side surface 10a may be used depending on the difference in radii of curvature of the corners M of the wall.
The outer surface 10b of the parting material main body 5 is a side surface on the side protruding from the corner portion M of the wall, and the cross section is formed in a substantially right angle shape (L shape). The reason why the outer surface 10b of the parting material body 5 is right-angled is that the part having the maximum width (width 1d) of the parting material body 5 is formed as thick as possible, so that the corner of the arc-shaped wall is formed by the parting material body 5. This is so that the entire gap between the portion M and the ceiling (floor) C can be covered. The right-angled shape of the outer side surface 10b simplifies manufacturing, in addition to the advantage of being able to cover the entire gap.
Here, it is assumed that the cross section of the outer surface 10b of the parting material main body 5 is substantially right-angled (L-shaped), but due to an error during manufacturing or the like, a slight arc shape (radius of curvature of 1 mm or less) is formed at the apex of the right-angled shape. It may be included.
The parting material main body 5 is made of a material such as resin, metal, or non-combustible material. If the parting material body 5 is a flexible resin, even if the radius of curvature of the curved surface of the corner M of the wall and the radius of curvature of the inner surface of the parting material body 5 are not the same, the parting material body 5 The deformation makes it possible to absorb the difference in the radius of curvature, and the parting member 1 can be closely attached to the corner portion M of the wall.
Further, when a material such as a non-combustible material is used for the parting material main body 5, it is possible to improve the fire resistance performance inside the building structure.

The protective portion 1 refers to the area around the center of the parting material main body 5, is attached to the apex of the corner portion M of the wall, and has a width sufficient to cover the entire gap between the corner portion M of the wall and the ceiling (floor). It is formed with 1d.
Since the inner surface of the protective portion 1 has an arcuate cross section and the outer surface of the protective portion 1 has a right-angled cross section, the center position of the protective portion 1 (the position of the apex of the right-angled outer surface) is the thickest ( width). 1d), the width gradually becomes thinner toward both ends.
At both ends of the protective portion 1, a pair of both end portions 2 and 2 of the protective portion are provided continuously from both ends of the protective portion 1.
The protection portion both ends 2 and 2 refer to the area around both ends of the parting material main body 5, and are attached with the apex of the corner portion M of the wall sandwiched. A pair of mounting portions 3 and 3 for mounting the parting material 4 of the above are provided.
Since the inner surfaces of both ends 2 and 2 of the protective portion have a straight cross section and the outer surfaces of both ends 2 and 2 of the protective portion also have a straight cross section, the both ends 2 and 2 of the protective portion are formed with substantially the same width 2d. , The width 2d is smaller than the width 1d of the protection unit 1. The width 2d of both ends 2 and 2 of the protective portion is substantially the same as the width of the other parting material 4 and as much as possible because another parting material 4 is attached to the end portion when the parting material 10 is used (FIG. 7). Make it inconspicuous. Preferably, the width is 2 mm to 5 mm.

Conventionally, if a gap W exists at the joint (cutting portion) between the corner portion M of the arc-shaped wall and the ceiling (floor), problems such as aesthetics and airtightness occur. It was necessary to cut in an arc shape along the corner M of the wall. However, the work of cutting the ceiling board (floor board) into an arc shape is very complicated and requires skillful techniques, so that workability is significantly impaired.
In the present invention, at the joint between the ceiling plate (floor plate) and the corner portion M of the wall, the ceiling plate (floor plate) is not cut in an arc shape, but follows the flat wall at both ends of the corner portion M of the wall. It is cut in a straight line to form a gap W between the ceiling plate (floor plate) and the corner portion M of the wall. Then, by using the parting material 10 having a width 1d capable of covering the entire gap W and covering the entire gap W, the gap W is made invisible from the outside. In order to cover the entire gap W, the protective portion 1 needs to be formed with a sufficient width 1d, but the radius of curvature of the inner surface of the protective portion 1 is substantially the same as the radius of curvature of the corner portion M of the wall. If the gap W is a gap formed by cutting the ceiling plate (floor plate) in a straight line along the flat walls at both ends of the corners M of the wall, the outer surface of the protective portion 1 is flat. Since the shape is formed by two straight lines parallel to the wall, it is possible to form a width 1d capable of covering the entire gap W.

FIG. 13 is a perspective view showing the parting material of the second embodiment of the present invention, and FIG. 14 is a plan view of the parting material of the second embodiment.
The parting material 10 of the first embodiment has a cross section of the outer surface 10b formed at a right angle (L shape), whereas the parting material 20 of the second embodiment of the present invention has an outer surface 10d. Is different in that is formed in an arc shape. Since the other configurations are the same, the same reference numerals are given to the same parts with respect to the same configurations as those in the first embodiment, and duplicate description will be omitted.

The parting material 20 of the present embodiment is a member attached to a joint (parting part) between a corner of a wall and a ceiling (floor) in interior work of a building structure such as finishing work of a wall, ceiling or floor. , A parting material main body 5 having a protective portion 1 attached to the corner portion M of the wall and a pair of protective portions 2 and 2 provided continuously at both ends of the protective portion 1 and attached to the wall. A pair of mounting portions 3 and 3 provided at both ends of the parting material main body 5 are provided (FIGS. 13 and 14).
The outer surface 10d of the parting material main body 5 is a side surface on the side protruding from the corner portion M of the wall, and the cross section is formed in an arc shape.

Figure 15 is an explanatory view showing a curvature radius of the relationship between the protection portion at both ends of the parting member of the second embodiment and the outer surfaces, (a) shows the case where the width 2d of the protecting portion both ends of 5 mm, ( b) is a case where the width 2d of both ends of the protective portion is 3.5 mm, (c) is a case where the width 2d of both ends of the protective portion is 2 mm, and FIG. 16 shows the protection of the parting material of the second embodiment. FIG. 2 is an explanatory diagram showing the relationship between both ends of the portion and the radius of curvature of the outer surface.
In order for the parting material 20 to cover the entire gap W between the corner portion M of the wall and the ceiling (floor), the radius of curvature r of the outer surface 10d of the parting material body 5 and the width 2d of both ends 2 and 2 of the protective portion Relationships are important.
Assuming that the gap W is formed by linearly cutting the ceiling plate along the flat walls provided at both ends of the corners M of the wall, the coordinates of the vertices of the gap W are set to (0,0). The inner side surfaces 10a of both ends 2 and 2 of the protective portion are on the X-axis and the Y-axis, and the outer surfaces of both ends 2 and 2 of the protective portion have widths of 2d = D and x = D and y = D. It is assumed to be on a straight line (Fig. 16).
Assuming as described above, when the outer surface 10d of the parting material body 5 passes through the coordinates (0,0) of the apex of the gap W and is a part of a circle having x = D and y = D as tangents. If the entire gap W can be covered, and the radius of curvature in that case is r _(0,0) , then r _(0,0) is used as the threshold, and if the radius of curvature r is larger than _{r (0,0), the gap} If the entire W cannot be covered and the _{radius of curvature r is smaller than r (0,0)} , the entire gap W can be covered.
Substituting the above conditions, r _(0,0) becomes the following (Equation 1), and the radius of curvature r is the width 2d (D) of both ends 2, 2 of the protection portion, as shown in the following (Equation 2). If it is within about 3 times, it is possible to cover the entire gap W.

When the width of both ends 2 of the protective portion 2 is 5 mm (FIG. 15 (a)), if the radius of curvature R of the outer surface 10d of the parting material 20 is within 15 mm, the entire gap W can be covered with the parting material 20. If the width of both ends 2 of the protective portion 2 is 3.5 mm (FIG. 15 (b)) and the radius of curvature R of the outer surface 10d of the parting material 20 is within 10.5 mm, the entire gap W is parting material. It is possible to cover with 20. Further, when the width of both ends 2 of the protective portion 2 is 2 mm (FIG. 15 (c)), if the radius of curvature R of the outer surface 10d of the parting material 20 is within 6 mm, the entire gap W is covered with the parting material 20. Is possible.

Even when the outer surface of the parting material is arcuate in this way, the width of both ends of the protective part of the parting material is the radius of curvature of the outer surface that can cover the entire gap W between the corner M of the wall and the ceiling (floor). By designing in consideration of the relationship with 2d (D), it is possible to cover the entire gap between the corner M of the wall and the ceiling (floor), maintaining the aesthetic appearance of the parting part and parting around the gap. It can be reinforced with materials, and it is possible to improve the work efficiency of interior work.

In the present embodiment, the case where the parting members 10 and 20 of the present invention are attached to the joint (parting part) between the corner portion M of the wall and the ceiling C has been mainly described, but the corner portion M of the wall and the floor have been mainly described. It is also possible to apply it to the seam (parting part) with.
