Abstract

A method for manufacturing a composite panel for lap joints may include a supply step of supplying a core sheet having a first width in one direction; a film lamination step of laminating adhesive films having the first width on the upper surface and the lower surface of the core sheet, respectively; a sheet lamination step of laminating an upper sheet having a second width wider than the first width on the upper surface of the core sheet on which the adhesive films are laminated, so as to protrude beyond both ends of the core sheet, and laminating a lower sheet having the first width on the lower surface of the core sheet; and a bonding step of joining the upper sheet, the adhesive film, the core sheet, the adhesive film, and the lower sheet by applying pressure.

Description

Method for manufacturing composite panels for standing seam, composite panels for standing seam manufactured by the same, and composite panels manufacturing device for performing the same The present invention relates to a method for manufacturing a composite panel for lap joints, a composite panel for lap joints manufactured thereby, and an apparatus for manufacturing a composite panel for lap joints for carrying out the same. More specifically, the invention relates to a method for manufacturing a composite panel for lap joints used to form the roof or wall of a multi-use facility, a composite panel for lap joints manufactured thereby, and an apparatus for manufacturing a composite panel for lap joints for carrying out the same. Generally, the roofs or walls of multi-use facilities such as factories, gymnasiums, and auditoriums can be constructed by installing and building lap joint panels on a structure or frame for forming the roof or walls of the building, or by using only lap joint panels without a structure or frame to install and build a shell structure. The above-mentioned interlocking panel may be a single panel made of a single metal sheet, or a composite panel made of a sandwich structure in which a core sheet is bonded between two metal sheets. In order to make the above composite panel for lap jointing, after forming the above sandwich-structured composite panel, both ends of one of the two metal sheets and both ends of the core sheet must be cut by a certain width. Therefore, manufacturing composite panels for lap joints can require a significant amount of time and cost.
