Ceiling under farmhouse
Reliable and without cracking.
The generally accepted structural movements are absorbed by the metal framework.
Differences in temperature and relative humidity do not cause dimensional variations in the plates.
BENEFITS
For new or old sites.
Low load under floors.
Integration of pipelines.
High performance.
Elimination of the risk of cracking
Ceiling on fur
(F530 or S47), plate
plaster in BA 13
mm. The frame on
frame or farmhouse
must be done with
screwed hangers (screws
of 35 for plate
plaster) or nailed (nail
galvanized) every
60cm maximum, between
axes of furs. The
along the fur, the
lines must be
at most every
1.20 m.
Standard pallet of 50 BA 13 in
2.50 by 1.20 = 150 m²
Galvanized nail
This extra large head point can be used for fixing a hanger on a structural beam and not on a truss. The truss vibrates when you nail.
A site manager observes an apprentice driving a nail. A few minutes later, he said to her:
“You remind me of lightning.
"Because I'm fast, huh?"
– No, because you never hit the same place!
The direct installation of plasterboard under a truss
industrialized is prohibited.
A standard ceiling, a BA 13 plus framework, weighs 12 kg per square meter.
Fire protection: 1/2 hour fire protection
Two screws per hanger
Fur hanger F 530 or S 47
Using a chalk line, whatever the type of support, trace and set up the four corner hangers.
Laser faster and much straighter. Gradually put on the lines.
Secure the intermediate legs with the cord, put on the furs.
Tip. The profiles can be positioned using metal rulers.
Laser line
Wall bracket for mounting most laser levels. It allows multiple fixing possibilities. The height adjustment with locking device offers a very precise adjustment.
A water level is made up of two graduated flasks joined by a pipe filled with water. It makes it possible to draw two points distant from each other on a perfectly horizontal line thanks to the principle of communicating vessels.

Flatness and horizontality tolerances
- Framework and ceilings
General flatness: 5 mm under the 2 m rule. The ruler being kept in contact with 2 support points on the plate.
Horizontality: 3 mm/m without exceeding 2 cm.
- Ceilings
Local flatness: 1 mm under the 0.20 m rule.
Ceiling frame fur
S47 - F530 length 3 or 5.30 m
Splint
Make the junction between 2 frames using a
splint and taking care to offset at least 1.20 m
the connections from one frame to another.

200 mm glass wool
In the case of insulation coated with a vapor barrier, the continuity of the vapor barrier is ensured by a taped strip.
200 mm glass wool with steam
Maximum height: 3.30 m
Remember to use pencil strokes against the wall, where the furs are.
Fur
Pencil stroke at the axis of the fur, before putting on the plate.
The plate lifter facilitates the handling of plasterboard
for ceiling installation.
Adjustable and lockable tilt angle.
Angle adjustment of the plate.
Possibility of tilting the plate beyond the horizontal
In order to make the joints at the end of the plate, fix the brackets corresponding to these joints 2 mm above the level of the other legs.
Clip the frames onto the legs. Place insulation if necessary. Screw the plates perpendicular to the frames.
All joints between plates must be aligned. (see diagram below)
2 mm above the other lines
Seal coated 25 mm screw
If the vertical walls are perpendicular.

2
If the vertical walls are perpendicular.
Place the first plate at an angle.
Place the other plates to be joined aligned (ease of treatment of the joints).
If the vertical walls are not perpendicular.
Attach the frame parallel to one of the vertical walls and
start with plate 1, with plate 2 on
after cutting the bias.

On the same frame (between axes 40 cm), two BA13. The more plasterboard there is, the better the acoustic performance.
It is reminded that the plate gaskets must be offset!
Here do not reassemble the 2mm lines at the end of the plate
It is advisable to putty on the periphery of the ceiling, to avoid later the passage of air on the electrical sockets of the dubbing.

Division joints
In order to allow differential movements, a fractionation joint must be made in the following cases:
- Large surface ceiling (over 300 m2)
- Structure made of different materials.
- Different types of configuration or direction of laying (eg: “L” shaped houses).
The industrial framework is made up of triangulated elements, called trusses, assembled by metal connectors.
Truss metal connector
A traditional frame is composed, unlike the industrial frame or farmhouses, of pieces of wood with a fairly large section. It is made up of trusses, themselves connected by purlins (sill purlin on the wall, possible belly or intermediate purlin in the middle of the pan, ridge purlin at the top).
The traditional frame contributes to the charm of many old houses. Made to measure, it is both aesthetic and easy to furnish.
The pieces of wood are not assembled by connectors as in the case of industrial frames. Three types of assemblies are used in traditional carpentry: bolting, nailing, or recessing.
