Abstract

PROBLEM TO BE SOLVED: To provide a corner bead which can be simply constructed and has the corner part having good appearance by forming the corner part of the corner bead previously according to the shape of the corner part of the wall surface. SOLUTION: A backplate such as plywood to which a polyvinyl chloride surface material or the like is, for example, stuck, is formed into a corner bead 11 having an internal angle of 90 deg. according to the wall surfaces 2a, 2b substantially intersecting perpendicularly to each other. At the time of fitting the corner bead to the chamferred wall surface, the corner bead is formed in such a manner that the internal angle in a designated position is 135 deg.. In the case of forming the internal angle of the corner bead 11, the backplate is cut to have a V-shaped section in a designated position, with a surface material left undone, and the cut surfaces are joined to each other by an adhesive agent. In the construction in a job site, linear corner beads 12a, 12b are butted and joined to both ends 11a, 11b of the corner bead 11. Accordingly, the construction is simple and the accuracy of the corner part is good, and as a cut portion is not provided in the surface of the corner part, it is possible to obtain the corner bead having good appearance, in which separation is not caused.

However, in the conventional on-site construction of the parting edges as described above, it is necessary for a considerable skill to butt the corners of the parting edges from the right angle. For example, in the butting by diagonally cutting the both cut edges at 45 °, which is the butting angle, the processing accuracy cannot be obtained, and thus there is a problem in that a gap is generated in the joint surface and the appearance is unsightly.

The present invention was made by paying attention to such conventional problems. The purpose of the present invention is to solve these problems and to provide a high accuracy without a gap between butting surfaces. The present invention provides a parting edge having a good-looking corner portion and a method for manufacturing the parting edge.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of a parting edge of the present invention according to claim 1. In FIG. 1, a parting edge 11 of the present invention is a floor 1 and a wall surface 2 (2a, 2b) of a building.
Are substantially orthogonal to each other, and are provided along the wall surfaces 2a and 2b of the parting portion having the right angle corner 2c.

The parting edge 11 is formed in conformity with the shape of the corner 2c where the wall surface 2a and the wall surface 2b are substantially orthogonal to each other, and the parting edge 12a of the straight part along the wall surface 2a, 2b from both ends thereof. , 12b are extended.

The inner angle of the parting edge 11 is the corner portion 2 of the wall surface 2.
Since it is manufactured according to 90 ° which is the angle of c,
It suffices if the both ends 11a and 11b are attached to the corner portion 2c as it is, and the end faces 12 of the skirting board 12a and the skirting board 12b.
It suffices to just butt and bond to c and 12d. Therefore, the construction of the parting edge 11 can be easily performed, unlike the conventional construction of the corner portion in the field construction, and the corner portion can be accurately formed and have a good appearance.

FIG. 2 is a perspective view showing an example of a parting edge of the present invention according to claim 2. In FIG. 2, the parting edge 21 of the present invention is such that the floor 3 of the building and the wall surfaces 4 (4a, 4b) are substantially orthogonal to each other, and the parting wall surfaces 4a, 4b, and 4c having chamfered portions 4c at the corners. It is provided along with.

The parting edge 21 is formed in a shape corresponding to the shape of 2c including a chamfered portion 4c at a corner where the wall surface 4a and the wall surface 4b are substantially orthogonal to each other.
The parting edges 22a, 22 of the straight portions are linearly extended along the line b.

The inside of the chamfered portion 21a of the parting edge 21 is manufactured according to the shape and angle of the chamfered portion 4c of the wall surface 4. Therefore, it suffices to mount it as it is in accordance with the chamfered portion 4c of the wall surface 4, and both end faces 21c, 21
end faces 22c and 22d of the parting edge 22a and the parting edge 22b
All you have to do is butt and join. Therefore, the parting edge 2
Unlike the conventional construction of the corner portion in the field, the construction of No. 2 can be easily performed, and the corner portion can be accurately formed and have a good appearance.

It is a material for making 0. The material 30A is composed of a back plate 31 made of plywood and a surface material 31 made of vinyl chloride resin that is attached to one surface of the back plate 31.
Also, the total length L of the material 30A is determined and determined from the finished dimensions at the time of completion, and is cut to that length.

FIG. 4 shows a state in which two V-shaped cuts, which are sharper from the back surface side to the front surface side, are cut at predetermined positions using the material 30A to form a chamfered portion. For example, the angle θ formed by the V cutting is 90 ° between the two ends 31a and 31a of the parting edge 30 that is finally completed.
Is calculated so that in this case, the cutting is performed at 45 °. Therefore, the angle formed between the end portion 31a and the central portion 31b is 135 °, and it is possible to join the chamfered portions of the wall surface in a closely contacted state without a gap.

The semi-finished product 30B, which has been cut as described above, has an adhesive applied to the cut surface and is bent and joined to form a parting edge 30 as shown in FIG. Will be completed.
