Method of manufacturing flat panels by juxtaposing and assembling longitudinal sections, sections used, and flat panels produced

摘要

The invention relates to a method for manufacturing flat panels by juxtaposing and assembling longitudinal sections (1) including two front walls connected by two lateral walls, known as sheets (4, 5) provided with interfitting structures allowing two juxtaposed sections (1) to be assembled. According to the invention, the sheets (4, 5) are pierced with orifices made in register, the orifices of one of the sheets (5) having larger dimensions than those of the orifices of the other sheet (4), then the juxtaposed sheets (4, 5) of the sections (1) are crimped together by moving through the orifices in register a drift (expander) whose dimensions match those of the orifices in the sheets (5), this drift being able to bring about plastic deformation of the periphery of the orifices of the sheets (4), causing the crimping.
