Benefits of technology
[0008]An invention according to claim 1, which achieves the above-described object, is an end treatment method of a laminated plate, including: a first step of supporting, by a support member, a thermoplastic resin-made laminated material in which a pair of plate-like members are laminated to each other while interposing a longitudinal wall so that a peripheral edge portion of the laminated material can be exposed, and heating and softening the peripheral edge portion by blowing a hot air to the peripheral edge portion; and a second step of pressing the plate-like member as one of the pair of plate-like members against other plate-like member by thrusting a cutting blade of a cutting die against the heated and softened peripheral edge portion, thereby bringing the pair of plate-like members into contact with each other and welding the plate-like members to each other, and then cutting the laminated plate out of the laminated material.

[0010]Moreover, an invention according to claim 3 is the end treatment method of a laminated plate according to either one of claims 1 and 2, wherein a coating material is pasted onto an outer surface of the laminated material.
[0011]Moreover, an invention according to claim 4 is a laminated plate including a thermoplastic resin-made body portion having a longitudinal wall portion and a pair of plate portions laminated to each other while interposing the longitudinal wall portion therebetween, wherein an end portion of the plate portion as one of the pair of plate portions is formed to be curved toward an end portion of other plate portion, and is welded to the other plate portion.
[0012]Furthermore, an invention according to claim 5 is the laminated plate according to claim 4, wherein a coating portion that coats an outer surface of the body portion is formed thereon.
Problems solved by technology
However, this type of laminated plate includes the core sheet having the longitudinal wall portions, and a thickness thereof is large, and accordingly, there has been a problem that an appearance of an end portion of the laminated plate is deteriorated if the end portion is just cut.
However, in the case of using such a method at the time of implementing the end treatment for a laminated plate having a complicated curved shape, a large wrinkle occurs on a portion with the complicated curved shape in the bent portion.
Accordingly, the bent portion concerned has not been brought into good contact with a side end portion of the laminated plate.
Specifically, in the above-described end treatment method, there has been a problem that restrictions occur on a shape of the laminated plate.

Abstract
A manufacturing method of a laminated plate (19) includes: a first step of supporting, by a support member (9), a thermoplastic resin-made laminated material (1) in which a pair of plate-like members (3, 4) are laminated to each other while interposing a longitudinal wall portion (2b) so that a peripheral edge portion (1a) of the laminated material (1) can be exposed, and heating and softening the peripheral edge portion (1a) by blowing a hot air to the peripheral edge portion (1a); and a second step of pressing the plate-like member (4) as one of the pair of plate-like members (3, 4) against other plate-like member (3) by thrusting a cutting blade (17a) of a cutting die (17) against the heated and softened peripheral edge portion (1a), thereby bringing the pair of plate-like members (3, 4) into contact with each other and welding the plate-like members (3, 4) to each other, and then cutting the laminated plate (19) out of the laminated material (1).
Description
TECHNICAL FIELD[0001]The present invention relates to a laminated plate and an end treatment method of the laminated plate.BACKGROUND ART[0002]Heretofore, as a laminated plate, there has been known one with a structure in which a core sheet having longitudinal wall portions such as, for example, honeycomb cores is laminated between other sheets. This laminated plate is cut into a desired outline shape, and is thereby used as an interior material, an exterior material or the like for vehicles and buildings.[0003]However, this type of laminated plate includes the core sheet having the longitudinal wall portions, and a thickness thereof is large, and accordingly, there has been a problem that an appearance of an end portion of the laminated plate is deteriorated if the end portion is just cut.[0004]In this connection, Japanese Patent Laid-Open Publication No. 2001-18308 (hereinafter, referred to as Patent Literature 1) proposes a laminated plate in which the appearance of the end porti...
