Abstract

PURPOSE:To enable the base ends of adjacent surrounding walls to be consecutively bent for allowing the application of satisfactory caulking treatment. CONSTITUTION:A continuous section 1b is preliminarily formed between the base ends of the opposite sides of each bent wall 3a around a body section 2 in bent and adjoining state for keeping the base ends integrally continuous to each other. When each wall 3a is bent toward the rear side of the body section 2 to form a continuous and bent surrounding wall 3 in the state where the side ends of the walls 3a are adjacent to each other between each bent and adjacent side 2a of the section 2, the sides ends of the walls 3a move toward each other. The continuous section 1b is thereby bent toward the rear side of the section 2, similar to the wall 3a, and deformed in such a way as forming the integrally continuous section 3c of the wall 3 between the base ends of the adjacent side ends of the walls 3a.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an exterior plate, and more particularly, it is mainly made of metal and is bent around the main body and bent to the back side so as to be continuous over adjacent sides. The present invention relates to a method for manufacturing an exterior plate having a peripheral wall.

[0002]

2. Description of the Related Art As an exterior plate having a bent peripheral wall, one used to exteriorize a building as shown in FIGS. 10, 11, 12 and 13 is known.

The exterior plate a shown in FIG. 10 is for a flat surface such as a flat wall surface or a flat pillar surface, and is provided on the four circumferences of a rectangular main body portion b which partially covers the flat wall surface or the pillar surface. It has a bent peripheral wall c. The four-fold bent peripheral wall c is formed by bending each bent wall d integrally formed on the four circumferences of the main body part a to the back side of the main body part a, and between the side edges of the adjacent bent walls d. Has a slit h formed by a seam in which these side edges continuously form a bent peripheral wall c over the entire length from the tip of the side edge to the base. An overlapping edge f is formed so as to extend outward from the tip of each bent wall d.

A plurality of exterior plates a are arranged vertically and horizontally as shown in FIG. 11 so that the overlapping edges f are overlapped with each other, and the portions of the overlapping edges f are nails, machine screws, bolts, etc. The exterior is made by hitting the wall surface of the body. The groove i formed between the peripheral walls c of the adjacent exterior plates a
Caulking material g is packed in the inside and caulking processing is performed. However, even with such caulking, the slit h extends to the vicinity of the surface of the main body portion b, so that it is difficult to close the slit h and prevent the intrusion of rainwater.

To deal with this, conventionally, the slits are filled with welded joints or adhesives, or the exterior plate a is used.
Squeezing the main body b without the slit as described above
It is performed to manufacture an exterior plate having a bent peripheral wall on four sides.

The exterior plate j shown in FIGS. 12 and 13 is used for the exterior of a wall surface corner portion of a wall surface or a pillar surface, or for covering as a cover. FIG. 12 shows a main body portion k which covers the wall surface or the wall surface corner portion of the pillar surface in the vertical direction or the horizontal direction, and the curved and adjacent main body portions k which are the joining edges in the vertical direction. It is composed of a separate member m individually attached to the side 1 by adhesive tape or spot welding,
A bent wall d forming a bent peripheral wall c and a overlapping edge f extending outward from the tip of the bent wall d are formed in the separate member m. A slit h is formed between the side edges of the adjacent separate members m.

However, in this case, each side l of the main body k
Is extended to the portion of the peripheral wall c formed by the bent wall d, the groove i portion formed between the adjacent main body portions k is overlapped by the overlapping of the overlapping edges f extending from the tip end of the bent wall d. The caulking material g of the caulking is firmly embedded in the groove i portion, and the rainwater by the slit h is continuously adhered to the surface side of the exterior panel j by the caulking material g and the inner surface of each protruding side l. Intrusion can be avoided.

FIG. 13 shows a case where the peripheral wall c of the main body portion k of the exterior plate j for the wall surface corner portion is formed in the same manner as in the conventional example shown in FIGS. 10 and 11, and the slit h in this case is formed. Since it is not possible to prevent rainwater from entering even by embedding a caulking material, it is necessary to take measures such as closing the slit h with welding or changing it to a drawing process.

[0009]

However, FIG. 10 and FIG.
In the structure as shown in FIG. 3, if welding is performed to close the slit h, the surface of the weld will be adversely affected. Therefore, after the processing for manufacturing the exterior plate accompanied by welding or the like, painting, alumite treatment, or hairline treatment is performed. It is necessary to carry out surface finishing such as treatment, and after processing, it is necessary to transport this to a factory that finishes the surface, surface-treat it, and further transport it to the site, which makes transportation and handling complicated, and cost is reduced. It will be expensive.

Further, in the case of adopting a drawn product, it is necessary to prepare an expensive drawing die for each size and shape of the exterior plate, which results in a high manufacturing cost.

Further, in the structure shown in FIG. 12, since the bending wall as a separate member must be attached to the main body of the exterior plate, this is also expensive, and an adhesive tape is used to simplify the attachment. When they are attached, they are often displaced or come off, and if they are dealt with in the field work, the work becomes complicated, and it is even more troublesome to take them home and deal with them.

An object of the present invention is to provide a method for manufacturing an exterior plate, which can obtain the exterior plate without the above-mentioned problems by a simple bending process.

[0013]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention bends each other around a main body and adjoins each other, or each fold extending outward from each side to be adjoined. Between the base portions of the side edges of the bending wall that face each other in the bent and adjacent state, a continuous portion that integrally connects these base portions is previously formed, and each folding wall is folded to the back side of the main body portion. By bending, the bent walls lean together at the side edges to form a continuous bent peripheral wall between the adjacent sides of the main body, and the side edges of the bent walls at this time approach each other. By the movement, the continuous portion is bent toward the back side of the main body portion like the folding wall, and is deformed to form an integral continuous portion of the folding peripheral wall between the base portions of the adjacent side edges of the folding wall, Bending the exterior plate with the base of the folding peripheral wall integrally continuous Formed is characterized in that.

In this case, it is preferable that the continuous portion is formed thinner than each bent wall.

[0015]

According to the above-mentioned structure of the present invention, the bent walls that are bent around the main body and are adjacent to each other, or outwardly extending from the adjacent sides are bent to the back side of the main body. Thereby, the bent peripheral wall can be formed to be continuous at the side edges of the bent wall adjacent to each other between the bent and adjacent sides of the main body, and at this time, the bent wall can be adjacent to the bent wall. In the state, between the bases of the side edges facing each other, a continuous portion formed in advance so as to integrally connect these bases to each other is formed by the movement of the side edges of each bent wall toward each other. Similarly, it can be bent to the back side of the main body part and deformed so as to form an integral continuous part of the bent peripheral wall between the base parts of the adjacent side edges of the bent wall. Therefore, between the bases of the side edges of the bent walls that are bent and are adjacent to each other or that extend outward from the respective sides that will be adjacent to each other, the bases of the side edges that face each other in the bent and adjacent state. It is possible to obtain an exterior plate in which the base of the bent peripheral wall is integrally continuous by simply forming a continuous part that is integrally continuous in advance and then simply bending the bent wall to the back side of the main body. it can.

In this case, if the continuous portion is thin, the continuous portion can be easily deformed when the adjacent bent walls are bent, so that the continuous peripheral wall portion can be formed in a natural shape without difficulty. be able to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Some embodiments of the present invention will be described below with reference to FIG.
-It demonstrates, referring FIG.

The first embodiment of the present invention shown in FIGS. 1 to 3 shows the case of an exterior panel 1 which is arranged vertically and horizontally to cover a planar wall surface as shown in FIG. 1 (a).

The exterior panel 1 has a foldable peripheral wall 3 of a quadrangular main body 2 which is bent while being flat and bent toward the back surface at four rounds formed by adjacent sides 2a. Is bent and formed by a bent wall 3a integrally extending outward from each side 2a of the four circumferences. From the tip of the bent wall 3a, a superposed wall 3b, which is overlapped at the time of placing and arranging, is integrally extended outward.

When the exterior panel 1 is placed vertically and horizontally as shown in FIG. 2, the adjacent walls 3b overlap each other.
Are polymerized with each other as shown in FIGS. 2 and 3,
Between the bent peripheral walls 3 of the exterior panels 1 adjacent to each other,
The caulking groove 5 is formed. A caulking material 6 is embedded in the caulking groove 5 for caulking to satisfy the waterproof property.

If there is a problem with this caulking process, the wall surface covered by the exterior panel 1 cannot be protected from wind and rain. When the bent peripheral wall 3 of the exterior panel 1 is formed by bending as in the present embodiment, the slit-shaped gap formed between the adjacent bent peripheral walls 3 cannot be closed even by caulking, and rainwater is not formed. Etc. may cause infiltration.

In the present embodiment, in order to obtain the exterior panel 1, the bent wall 3a and the overlapped wall 3a are formed on each of the four adjacent sides 2a of the main body 2 which are bent and adjacent to each other as shown in FIG. 1 (a). A flat plate-shaped material 1a formed by integrally connecting the walls 3b is used. And this material 1a is shown in Fig. 1 (a).
By bending at the portion of the bending line 26 shown in FIG. 1, the bending peripheral wall 3 and the overlapping wall 3b as shown in FIG.
The three-dimensional exterior panel 1 having is formed by bending.

At this time, as shown in FIG. 1 (a), each side 2a of the raw material 1a is bent around the main body 1 and is in an adjacent state.
A continuous portion 1b is formed between the base portions of the side edges of the respective bent walls 3a facing each other so as to integrally connect these base portions. Then, by bending each of the folding walls 3a toward the back side of the main body 2, the folding wall 3a is leaned toward its side edge portion between the adjacent adjacent sides 2a of the main body 2 to form a continuous folding peripheral wall 3. It can be formed as shown in FIG.

At this time, the continuous portion 1b formed in advance between the base portions of the side edges facing each other in the bent adjacent state of the bent wall 3a so as to integrally connect these base portions, The folding walls 3a are bent toward the back side of the main body 2 by the movement of the side edges of the folding walls 3a toward each other in the same manner as the folding walls 3a, and the folding peripheral wall is formed between the bases of the adjacent side edges of the folding walls 3a. 3 can be deformed to form an integral continuous portion 3c.

Therefore, between the bases of the side edges of the bending walls 3a of the main body 2 which are bent and are adjacent to each other or which extend outward from the respective sides 2a which are to be adjacent to each other, which are opposed to each other in the bent adjacent state. The base portion of the folding peripheral wall 3 is integrally continuous by simply forming a continuous portion 1b for integrally connecting the base portions in advance and then simply bending the bending wall 3a to the back side of the main body 2. The exterior panel 1 that is integrally continuous can be obtained at the portion 3c, and can be easily and inexpensively manufactured.

For this reason, surface finishing as a post-process is not necessary, and even the surface-finished one does not have a bad influence as in the case of welding, so that it can be directly transported to the site for use.

Particularly, in the above bending process, as shown in FIG. 4, the block 7 is applied to the bending portion of the material 1a, and the material 1a is simply bent along the block 7 along the bending line 26. Even if the size of the exterior panel 1 is increased, the blocks 7 may be arranged such that the small blocks are separated from each other on the left and right sides as shown in FIG. The bending process can be sufficiently achieved, and the processing cost can be remarkably reduced as compared with the case where the drawing process is performed.

Moreover, the exterior continuous panel 1 formed as described above is directly placed vertically and horizontally as shown in FIG. 2 by the integral continuous portion 3c formed at the base of the bent peripheral wall 3 of the main body 2 so that they are adjacent to each other. When caulking is performed by filling the caulking material 5 in the caulking groove 5 formed between the bent peripheral walls 3, the slit-shaped gap 11 formed between the adjacent bent peripheral walls 3 has a base portion of the bent peripheral wall 3 of the main body 2. Since the integral continuous portion 3c formed in the length is short enough not to reach the base portion of the bent peripheral wall 3, as shown in FIG.
One is blocked, and the infiltration of rainwater can be well prevented.

Further, in the case of this embodiment, since the continuous portion 1b is thin, the continuous portion 1b can be easily deformed when the adjacent bent walls 3a are bent. Instead, it can be formed in a natural shape.

Although the exterior panel 1 having the quadrangular main body 2 is shown in this embodiment, the present invention is not limited to this, and a triangle or a polygon can be similarly formed according to the above-mentioned embodiment. .

Further, in this embodiment, the continuous portion 1b is replaced with the material 1a.
It is formed by narrowing it down from the back side so that the front side is flush, but it may be formed by narrowing down from the front side so that the back side of the material 1a is flush. Further, the material 1a may be narrowed down from both the front and back sides to form a step on both the front and back sides.

Needless to say, the continuous portion 1b can be left to have the same thickness as the main body 2 and the bent wall 3a.

These can be applied to all of the embodiments shown in the present invention and to all of those belonging to the category of the present invention.

The second embodiment of the present invention shown in FIGS. 5 to 7 shows the case of the exterior panel 21 used for covering the corners of the wall surface such as the corners of a building or a pillar.

In this embodiment, the bending wall 3a and the overlapping wall 3b are formed on each side 22a which is bent and adjacent to the main body 22 in the usage pattern.
The material 21a as shown in FIG. 5 (a), which is formed so as to be integrally continuous, is used.

Between the bases of the side edges of the folding walls 3a adjacent to each other on both sides of the folding line 24 of the main body 22 which are opposed to each other in the bent and adjacent state, a thin continuous portion 21b for continuously connecting the bases together. Has been formed.

In order to obtain the exterior panel 21 from this material 21a, the material 21a is bent at the bending lines 26 and 2 shown in FIG. 5 (a).
The four parts are bent in the direction shown in FIG. 5 (a) to form the shape shown in FIG. 5 (b). At this time, the continuous portion 21b is deformed due to the side edges of the adjacent bending walls 3a being brought closer to each other, and the base portion of the bending peripheral wall 3 formed by the bending is similar to the case of the first embodiment. The integral continuous portion 3c can be formed.

Therefore, the exterior panels 21 are placed side by side in the longitudinal direction of the wall surface corners covered by the exterior panels 21 as shown in FIG. 6 so that the overlapping walls 3b are overlapped with each other, and at this time, they are formed between the adjacent bent peripheral walls 3. When caulking is performed by embedding the caulking material 6 in the caulking groove 5, a slit-shaped gap 11 is formed between the bent peripheral walls 3 on the tip side.
As can be seen from the above, it can be sufficiently closed, and the same operational effect as in the case of the first embodiment can be exhibited.

Further, as shown in phantom in FIG. 5 (a), it is possible to form a cut 32 toward the bent wall 3a on one or both sides of the continuous portion 1b. By providing such a cut 32, it is possible to absorb the deformation distortion of the bending wall 3a and the continuous portion 1b when the bending wall 3a is bent to the back side of the main body 2, and the main body 2 and the bending peripheral wall. It becomes easy to ensure the airtight continuity of 3 and the integral continuous portion 3c thereof.

In this case, as shown in FIG. 5C, when the thin continuous portion 21b is appropriately extended by utilizing the forming range of the slit 32 and formed wide, the occurrence of deformation strain can be further suppressed. it can.

Such a point can be similarly applied to all of the embodiments of the present invention, and can be applied to all of the categories belonging to the present invention.

FIGS. 8 and 9 show the third and fourth embodiments of the present invention. In the third embodiment of FIG. 8, the thin continuous portion 21b of the material 21a for forming the exterior panel 21 of the type of the second embodiment is formed in a wavy shape that undulates in the compression deformation direction. In the fourth embodiment of No. 9, a plurality of concave grooves 31 arranged in the compression deformation direction are formed in the same continuous portion 21b.

In these cases, the corrugated shape of the continuous portion 25 and the concave groove 31 facilitate the compression deformation when the side edges of the bent peripheral wall 3 are brought closer to each other. For this reason, the continuous portion between the base portions of the bent peripheral wall 3 formed at the edge of the main body 22 can be formed more easily and without cracks or cracks.

The concave groove 31 in the embodiment of FIG. 9 may be provided on the surface opposite to the continuous portion 1b or on both surfaces. When applying on both sides, the formation position can be shifted from the front to the back,
The deformability of the continuous portion 1b can be adjusted by not shifting.

[0045]

EFFECTS OF THE INVENTION According to the present invention, the bent walls of the main body which are bent and adjacent to each other, or the bent walls which extend outward from the adjacent sides, face each other in the bent and adjacent state. Between the bases of the edges, a continuous part that integrally connects these bases is formed in advance, and then the base of the folding peripheral wall is formed by a simple work of bending the bending wall to the back side of the main body. An integrally continuous exterior plate can be obtained, which can be easily and inexpensively provided. In addition, since using a material that has been surface-finished in advance does not have the same adverse effect as when performing welding, there is no need for troublesome handling such as transporting the surface finish to another factory after processing. It is also advantageous in terms of transportation and handling, and costs can be reduced.

In this case, when the continuous portion is thin, the continuous peripheral wall portion can be easily compressed and deformed when the adjacent bent walls are bent, so that the continuous peripheral wall portion can be formed in a natural shape without difficulty. It is possible to improve the yield.
