The length of the walls is 5 m, height — 2,5 m, width 10 cm Assembling of the structure will be made of the guide profile 50×40 mm. Plasterboard is 12.5 mm in two layers. The first layer of drywall will be installed horizontally. The second layer vertically. Also, install insulation thickness of 5 cm.
Measure out from the wall with a tape measure, where the partition will be. Set the laser level "crab" on the floor. Press the desired button so that the laser shows the lines on the ceiling, wall and floor. When the surfaces are smooth, we “beat off” the marks with the “jingle” cord; if not, then on the laser lines with a marker or a pencil we make marks so that the guides “lie down” smoothly, along clearly defined lines.
We already have lines on the ceiling, walls and floor. We glue the sound-proof damping tape on the profile guides from the back side, that is, from below. This is done from the noise vibrations that pass through the walls and floor. Then install these guides on the ceiling, floor and walls.
And here is the most interesting thing: instead of the rack profiles, we will use the same guide 50 × 40 mm, only twisted together with press washers. Since our height is 2.5 m, we cut two profile guides 50 × 40 mm 2.5 m each. We twist them together so that the ribs are facing outwards. When installing profiles vertically, we take a step every 60 cm. We connect the guides at the joints with each other with a sifter (very often the masters twist the pressing washer, and then in these places there are irregularities).
Why do you need to twist the profile 50 × 40 mm between each other?
In the usual design, we put a rack profile, and this is 5 cm, where two sheets of drywall will dock. When we twist the edges of one sheet, the screw will go into the profile where there is rigidity. But when we tighten the second sheet, the screws will bend the profile and the drywall in this place will sag. This is a common disadvantage of this method.
- When we install a double guide profile 50 × 40 mm, this gives an end face of 8 cm, where the drywall is very well and securely fastened.
The cross-section guides of the 50 × 40 mm are “doubled” in the same way as the vertical ones. They will be fastened through every meter. The opening will be 1 m by 60 cm, where it will be easy to insert the mineral wool. As a result, we will have a construction where the profiles are installed in 60 cm increments.
We have not yet spun drywall, but the frame is already very durable. What cannot be said when we assemble the frame in the usual way. All the masters know: until you twist the drywall, the frame is flimsy. And according to our new method without twisting drywall, the frame becomes already a “monolith”. All the joints between the transverse and vertical profiles are stitched together with a sifter.
We install the first drywall layer horizontally. The second layer is vertical. Good advice: on the first layer of drywall a lot of screws do not twist, because there will be a second layer, where we twist in full.
This method is practiced by many masters. Because it is reliable and practical. Plasterboard designs are constantly being improved. I do not know who invented this frame assembly method. But definitely, he is better than the one that was before.
