Arched partitions
The explanations given below relate exclusively to plates 6, 10 or 13 mm thick.
Except in particular cases, the development of the bending is preferably carried out in the direction of the length of the plate.
For example, for a curved partition the plates are arranged horizontally.
The frames are always perpendicular in the direction of the length.
The tighter the bending radius, the more delicate the work of the plate. It is easier to bend plates of reduced width.
For a radius greater than 2 m, bending a standard 13 mm plate is done without special precautions.
The center distance between the frames is 0.40 m maximum.
For a radius less than 2 m, the plates are softened beforehand by humidification.
The bending radius can then be reduced to 1.50 m for a BA13.
1.00 m for a BA10.
0.60 m for a BA6.
The center distance of the frames is 0.20 m maximum.
For a radius of less than 1.50m, the previously wet plates are placed on a template specially prepared for
bending dimensions.
The plates should gradually take the shape of the template. The reasonable minimum radius is 1.20m.
The center distance of the frames is 0.20m maximum.
curved partitions
The floor and ceiling rails are replaced by CR2 angles. One wing of each angle is notched to allow shaping
The two angles are positioned face to face to reconstitute the rail, and
rigorously fixed according to the layout
With a rail of 48,
Secure the rail to the ground with 6 diameter plugs, lengths 25 mm on a slab
Cut the rail approximately every 15 cm
Post the rail to the ceiling using the plumb line
Fix the uprights of 48 doubled every 40 cm
Rail or provisional upright all 2 uprights were fixed to the ground then at 1.20 m on uprights, to prevent the uprights from flexing, when you are going to tackle the first plate.
Fix the plate, taking care to screw well on the 2 uprights which are back to back
Do not fix the bottom of the plates to avoid deforming the rounding
To obtain perfect continuity in the curvature, it is desirable to join the ends of the plates in part planar.
The inevitable flatness is always difficult to catch up
Examples of curved ceiling frames
Work of curved plasterboard.
Make an arch in a corridor, take the width of the corridor, add 10cm on the BA13 (width of the arch 20, 30 or 40cm, or even more), take the plate, wedge it between the two
walls in the desired location, make the framework (see diagram), put the two plates (BA13) on each side, screw in, cut what protrudes and join.
Fix the BA13 on each side
Arch width to the size you want
Fix the rail cut first approximately every 15 cm
Cut, join

another example
Another way of proceeding.
Cut the BA 13 x 2 as desired.
Secure the BA 13 with the 25 mm screws.
Place the rail at the bottom of the plate.
Fix the rail to the ceiling, then on the sides
Attach BA 6 or BA 13
