CONSTITUTION:The main body molding surfaces 2a, 3a forming a cavity part 1a of panel main body of plate state on the surfaces facing each other and the molding surfaces 2b, 3b of U-shaped engaging part forming a cavity part 1b thereof by interconnecting the tenminal end with the main body molding surfaces 2a, 3a, are intermittently arranged at a constant interval to the longitudinal direction of panel on a pair of forces 2, 3 capable of clamping. At the same time, the convex part 2c forming a hole required for forming a vacant part 1c for inserting spacer is, in a body, protruded by the length for jetting out from the inner surface of concave part 2b forming the one side engaging part of the force 2 into the concave part 3b forming the another engaging part of the force 3 and further for aligning the shape of inner surface of the cavity part 1b of engaging part.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing wall panels in which panels are connected to each other by engaging U-shaped retaining portions provided at their connecting ends in a keyboard-like manner. .

Conventionally, as shown in FIG. 1, wall panels as shown in FIG.
In b, fold the connecting end of one side wall panel a outward to form a U-shaped retaining part a', and fold the end of the other wall panel b** outward in an L-shape. A retaining portion b' is provided by bending the remaining end and folding it back inward in a dented shape, and these retaining portions ma' and b'
In this way, the above-mentioned wall panel a%b has a shape that cannot be cut out and is loose, so it must be formed by extrusion molding.
When using this molding method, even if there were small scratches on the surface of the wall panel in the extrusion direction, or if a pattern was to be provided on the surface, it could only be created in the extrusion direction. , because a thermoplastic material with low hardness had to be used, there was a problem that it was not possible to form a single panel with high strength.Also, the wall panels a% and b of the above structure were arranged in the width direction and in the same line. When connecting in a shape, the tip of the folded piece a'' of at least one of the retaining portions a' must be held against the 1ia wall b'' of the other force retaining &11b'. If they are placed in a row within the interval of , there is not a small amount of dimensional tolerance, and as a result, the abutting points do not engage, causing the wall panel to wobble.

Therefore, the applicant first connected the above-mentioned engaging portions a' and b' to wall panel a, as shown in FIGS. 2 to 6.

A plurality of panels a and b are formed intermittently at the connection base of b, that is, with predetermined dimensions, in the length direction of the panels a and b, and on the outer wall of one of the retaining portions b', A hole b" for inserting a spacer with the same length as the retaining part b' is provided, and after the retaining parts a' and b't" are engaged with each other, the hole b is inserted.
Insert the spacer 〇 from ``'' and fix both wall panels a% b to the spacer c1 as shown in Figs. .

The wall panel a%bt can be moved and adjusted in the width direction within the effective width range of b''''', and thus a wall panel has been developed that can be simply and easily erected at constant intervals.

The present invention provides a manufacturing method applied to molding a wall panel having the above-mentioned structure, and its purpose is to provide an intermittent mouth-shaped retaining portion at the connecting end and an outer wall thereof. Wall panels with holes for inserting spacers can be integrally molded by press molding or injection molding, making it possible to create a smooth surface with a one-point pattern, as well as being able to use thermosetting materials to increase strength. Its purpose is to mold large wall panels.

The present invention will be described in detail below based on the embodiment shown in FIGS. 7(A) and 7(B).

First, the mold +21131 such as a press mold is used as a molding mold, and the molds (2) and (3) are not shown in the figure so as to close and open the mold in the plane direction of the wall panel (1) to be molded. It is attached to the molding machine.

Both molds t21+31 have body molding surface portions+ that form plate-shaped panel body cavity portions 11) a on opposing surfaces, respectively.
2) a, 131 a, and the mouth-shaped engagement portion molding surface portion +21 b, +31 b, which communicates with the end portion to form the mouth-shaped retaining portion cavity portion (1) b, are in the longitudinal direction of the panel. The engaging portion molding recesses (2) of one mold (2) are formed intermittently at regular intervals.
From the inner surface of b, the engaging part molding recess 13 of the other mold (2)
Spacer insertion space + 1 to a length that protrudes into 1 b and matches the inner surface shape of retaining part cavity part (1) b.
) The hole-shaped protrusion (2) where C is to be formed is formed by protruding integrally. The present invention is carried out using the mold +21 +31 formed in this way. The mold clamping and mold opening means are the same as those of known press molding and injection molding.When the mold is clamped, as shown in the figure, the mold recesses 12 are formed between the opposing surfaces of both molds (21+31). a, 13) as12
) b and 131 b form a cavity, thereby forming a panel body cavity part (1) a and a retaining part cavity part (1) b which is intermittently continuous at the end in a mouth shape. can do.

Here, since there is no folded piece b"" between each of the intermittent opening-shaped retaining parts b' and b' at the connecting end of the wall panel b, as shown in Fig. 7 (■), Both types + 2) (31 can be opened in the direction of arrows d and d' shown in the figure, that is, in the plane direction of the Maro panel.

On the other hand, in the joining part cavity part (1)b, one mold (2)
The spacer insertion cavity 11) is formed by the hole bottom mold protrusion (2)C protruding from the hole bottom mold protrusion (2)C, and the hole bottom molding protrusion (2)C protrudes in the mold clamping and mold opening directions. Furthermore, the tip surface of the protrusion (2) C and the other M (3)
) The folded piece molding surface part 13) b' and the folded piece cavity 71 in which the folded piece b11111 is to be molded.
Since part (1) b' is formed, mold clamping and mold opening can be performed freely in a straight line, and as a result, the folded piece 1.11111, that is, the mouth-shaped retaining part b' is integrally molded. Ru.

As explained above, the present invention has a panel body cavity formed between the body molding surfaces of each mold by clamping a pair of molds, and a U-shaped engagement cavity that communicates with the end of the panel body cavity. By forming a hole forming protrusion intermittently in the retaining part cavity part and protruding from one mold toward the other mold, the retaining part cavity part is formed intermittently. After forming the folded piece cavity part and molding the wall panel by press or injection molding using the cavity between both molds, the mold is opened to form a U-shaped retaining part intermittently at the connecting end, Since the wall panel has a hole for inserting a spacer corresponding to the folded piece on the outer wall of the retaining part, the wall panel having the folded piece in the retaining part can be molded without extrusion molding. It can be manufactured by molding by opening a mold, so there are no small scratches on the surface of the wall panel, making it possible to create a beautiful surface and even create a one-point pattern.In addition, the wall panel is stronger than molded products. 0 that can be molded
