DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a corner panel by connecting cut pieces cut out from a panel original plate.

[0002]

2. Description of the Related Art As shown in FIG. 3, a panel body 2 and a curtain plate portion 3 formed along the width direction of the panel body 2 are provided. While the vertical joint 30 is provided, the panel body 2 has a panel joint plate 1 provided with a central joint 20 having a joint width wider than the vertical joint 30 and continuous with the vertical joint 30 at the center of the curtain plate portion 3. Are known. The panel base plate 1 is used as it is as an outer wall panel, and the panel base plate 1 is further cut and connected to form a corner panel 10 (see FIG. 2).
It has been made.

[0003] Conventionally, when a corner panel 10 is manufactured from this panel base plate 1, as shown in FIG. 4, a cut-out plate 4 of a right angle chevron that expands in diameter from the front surface to the back surface of the panel base plate 1 is used. The portion 3 was cut along the joint of the vertical joint 30 to form the inclined cut surface 11. in this case,
The cut line 4 of the original panel 1 was cut so that the joint bottom 31 of the vertical joint 30 was cut off to leave the tapered surface 32. Then, the inclined cut surfaces 11 are connected to each other in an L-shaped cross section, and the connection corner 2a of the panel main body 2 matches the connection corner 3a of the curtain plate 3 so that the connection corner 1a has substantially the same finish. Finishing was performed by performing chamfering process 5. In this case, the chamfer width A of the connection corner 1a is finished to be approximately twice the width of the tapered surface 32 of the vertical joint 30.

[0004]

However, the conventional panel blank 1 has a central joint 20 having a large joint width at the center of the panel main body 2. Therefore, in the conventional cutting method, the central joint 20 is continuous with the central joint 20. When the corner panel 10 is to be manufactured by cutting a portion of the vertical joint 30 to be formed, the connection corner 2a of the panel body 2 is depressed more than the connection corner 3a of the curtain plate portion 3, as shown in FIG. . Therefore, the cross section L
After the connection, the connection corners 1a have to be chamfered 5 on the connection corners 3a of the curtain plate 3 so as to match the connection corners 2a of the panel body 2. In this case, the curtain The connecting corner 3a of the part 3 must be excessively chamfered,
The chamfer width A of the connection corner 1a becomes too large, and a good product for the corner panel 10 cannot be obtained. Therefore, the central joint 20 cannot be used for manufacturing the corner panel 10, and the manufacturing efficiency of the corner panel 10 from one panel original plate 1 is low.

The present invention has been made in view of the above circumstances, and has as its object to provide a method for efficiently manufacturing a corner panel from a panel original plate.

[0006]

A method of manufacturing a corner panel according to the present invention for solving the above problems includes a panel body, and a curtain plate formed along the width direction of the panel body. On the curtain plate portion, vertical joints are provided at predetermined intervals, while on the panel body, a central joint that is wider than the vertical joints and that is continuous with the vertical joint at the center of the curtain plate portion is provided. A panel plate is formed, and this panel plate is
A right-angled angled cut line that expands from the front surface to the back surface of the panel base plate, cuts along the joints of the vertical joints of the curtain plate, and connects the inclined cut surfaces formed by this cut into an L-shaped cross section In addition, a method of manufacturing a corner panel formed into an L-shaped cross section by chamfering a connection corner portion, wherein the corner panel is cut at a cut line for completely cutting off the joint bottom at the center joint.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a manufacturing process of the corner panel 10, FIG. 2 shows the manufactured corner panel 10, and FIG.
Is a panel original plate 1 used for manufacturing the corner panel 10.
Is shown.

That is, the method of manufacturing the corner panel 10 is configured by cutting the panel base plate 1 and connecting the cut surfaces 11 to each other.

The original panel panel 1 includes a panel body 2 and a curtain plate 3 formed along the width of the panel body 2. Among them, the curtain plate portion 3 is provided with nineteen vertical joints 30 at intervals of about 50 mm. The panel body 2 has a joint width wider than the vertical joint 30,
A center joint 20 which is continuous with a vertical joint 30 at the center of the curtain plate portion 3 is provided. Further, the panel body 2 has a length of about 60 m.
Horizontal joints 23 are provided at intervals of m.

The vertical joint 30 is formed such that the depth D1 is 4.2 mm, the joint width L1 is 12.4 mm, the joint bottom width W1 is 4 mm, and the taper angle θ1 is 45 °. The center joint 20 has a depth D2 of 4.2 mm and a joint width L2 of 16.
4mm, joint bottom width W2 is 8mm, taper angle θ2 is 45 °
It is formed so that it becomes.

From the panel original 1 to the corner panel 10
1A, first, as shown in FIG. 1A, the joint bottom 21 of the central joint 20 is completely cut off by a right angled cut line 4 whose diameter increases from the front surface to the back surface of the panel original plate 1. Cut so as to leave the tapered surface 22. Then, the inclined cut surfaces 11 formed by this cutting are cross-section L
Connect in the shape of a letter. In this connection state, the connection corner 1a is more connected to the connection corner 3 of the curtain plate 3 than to the connection corner 2a of the panel body 2.
a protrudes, the connection corner 2 of the panel body 2
chamfering 5 of the connection corner 3a of the curtain plate 3 so as to fit
I do. The corner panel 10 obtained by performing the chamfering process 5 in this manner has a chamfered width A of the connection corner 1a approximately twice as large as the tapered surface 22 of the center joint 20. Since the tapered surface 22 of the center joint 20 is the same as the tapered surface 32 of the vertical joint 30, the corner panel 10 thus obtained has a chamfer width A of the connection corner 1a as shown in FIG. Does not grow.

Therefore, considering the original panel 1 shown in FIG. 3, a corner panel 10 having a shape as shown in FIG.
Can be manufactured from one panel original plate 1. As described above, when five corner panels 10 are manufactured from one panel original plate 1 and at least the central joint 20 is cut, the joint bottom 21 of the central joint 20 as shown in FIG. The corner panel 10 may be manufactured by cutting at the cut line 4 to be cut. Therefore, when the corner panel 10 is manufactured by cutting a portion of the vertical joint 30 other than the central joint 20, the cut line 4 for cutting off the joint bottom 21 of the central joint 20 as shown in FIG. As shown in FIG. 4, a cut line 4 for cutting the joint bottom 31 of the vertical joint 30 may be used. However, it is more efficient to unify the cut line 4 for cutting off the joint bottom 21 of the center joint 20 from the viewpoint of workability.

In the present embodiment, the original panel panel 1 is used, in which the panel 3 is provided at the upper end of the panel main body 2. The panel 3 is provided at the lower end of the panel main body 2. May be provided, may be provided at the upper end and the lower end, or may be provided at an intermediate portion.

[0015]

As described above, according to the present invention, since the center joint is cut by the cut line for completely cutting off the joint bottom, the center joint is connected in a state where the inclined cut surfaces are connected in an L-shaped cross section. Can be prevented from being depressed at the connection corner. Therefore, it becomes possible to manufacture a corner panel using this central joint,
Since the center joint portion of the panel base plate can be used without being discarded, the production efficiency of the corner panel from one panel base plate is improved.
