Abstract
The present invention concerns a construction element, in particular containing plaster, in a plate which includes reinforcements distributed throughout the greater part of its thickness, such that along lines parallel to the sides of the plate, the reinforcements are concentrated in predetermined zone of the thickness and the plaster is removed plumb with these lines which may thus become folding lines to achieve a non-planar element. The invention also concerns a process and apparatus for manufacturing these construction elements. The invention applies, in particular, to the manufacture of U-shaped plasterboard panels for use in ceilings and in building structures.
Claims29
A construction element of plaster comprising:
- a plate having opposed faces, reinforcements distributed throughout the greater part of the thickness of the plate, and folding lines parallel to the faces of the plate comprised of the reinforcements concentrated by compression to a reduced thickness separating the plate into a plurality of articulated panels.
Construction element according any one of the preceding claims, characterized in that the folding lines where the reinforcements are concentrated are parallel.
A construction element of plaster comprising:
- a plate including fiber reinforcements distributed throughout the greater part of its thickness,
- said reinforcements being concentrated at spaced folding lines parallel to the faces of the plate in a plane so that the fibers are not expanded but are reduced to the thickness of about the thickness of the fibers,
- the material constituting the matrix of the plates being eliminated plumb with the folding lines where the reinforcements are concentrated in such a way as to thus constitute a plurality of panels joined by reinforcements,
- the different panels being folded back around said folding lines so as to form a non-plane product,
- including two parallel folding lines delimiting three panels with the lateral panels being of a lesser dimension than the central panel so as to form after folding a trough with two flaps,
- the angle of the flaps with the central panel being about 90.degree.,
- and the edge of two consecutive panels which are close to each other or in contact on folding being glued together.
