Title (EN) TAPERED PLASTERBOARDS AND METHODS FOR MAKING THEM
(FR) PLAQUES DE PLÂTRE EFFILÉES ET LEURS PROCÉDÉS DE FABRICATION
Abstract:
(EN) Disclosed herein are plaster boards having a first surface and an opposing second surface, and a first edge and an opposing second edge that bound the first surface and the second surface. The first surface includes a first section and a second section, the first section being raised compared to the second section, the second section abutting the second edge. The second surface includes a first section and a second section that are separated by a boundary between the first edge and the second edge. The first section of the second surface is substantially parallel to the first section of the first surface. The second section of the second surface slopes toward the first surface from the boundary toward the second edge. Methods for making the plaster boards involve forming wet plaster material and drying the wet plaster material such that the wet plaster material hardens into a plasterboard.
(FR) La présente invention concerne des plaques de plâtre qui ont une première surface et une seconde surface opposée, et un premier bord et un second bord opposé qui sont liés à la première surface et la seconde surface. La première surface comprend une première section et une seconde section, la première section étant levée par rapport à la seconde section, la seconde section étant contiguë au second bord. La seconde surface comprend une première section et une seconde section qui sont séparées par une limite entre le premier bord et le second bord. La première section de la seconde surface est sensiblement parallèle à la première section de la première surface. La seconde section de la seconde surface est inclinée vers la première surface depuis la limite vers le second bord. Des procédés de fabrication des plaques de plâtre impliquent la formation d'un matériau de plâtre humide et le séchage du matériau de plâtre humide de telle sorte que le matériau de plâtre humide durcisse en une plaque de plâtre.
