Plasterboard widespread material for decoration for various purposes.Features such finishes are almost limitless.
Today we talk about one of the ways.
Features wooden ceiling
GCR in a wooden house
Nowadays, not uncommon when using drywall ceilings are held not only in the homes of brick and concrete, and in wooden houses.
plasterboard in a wooden house can be both simple and multi-level.
As a rule, such a ceiling is arranged in two cases:
- ceiling coverings of a new home.
- ceiling coverings of the old house.
In both cases, this design allows a much easier finishing, allowing end up getting excellent coverage.Simple at first glance, when we look at the operation is not quite simple.
From our resources we have repeatedly described how devices from different ceilings of plasterboard.In all cases, the basic approach to the creation of the cover is almost identical for the small exceptions.
not an expert in this matt
But it is a common misconception.Fixing plasterboard to the wooden ceiling is not straightforward as it might seem at first sight, and it's like this.
Reconfiguration - the main problem
Any wooden structure - is primarily a mobile structure. Variations in temperature, humidity and natural shrinkage of the wood create the preconditions that the wooden structure is constantly moving in different directions, changing its configuration invisible to the eye.
Unlike wood, drywall deprived of such an opportunity:
- Suppose you set plasterboard ceiling in a wooden house in the usual way.
- still use special metal profiles and suspensions designed for this purpose.
- at the seams glued serpyanka by all the rules.
- ceiling primed, plastered and painted.
Cracks - the main headache
takes a certain time and you will notice on his previously perfect ceiling cracks formed in the joints of individual sheets.This fracture increases with each passing day.
you blame the builders, and when the installation was carried out with their own hands, poor-quality mixes.What incidentally, in our time is not uncommon.Spend
repeated repair, but after a while everything is repeated.
diagnosis - incorrect installation
What is the reason, which allowed a miss?
thing is that the installation of drywall on the wooden ceiling was implemented incorrectly.Fixed frame can withstand changes occurring with wooden house for predictable reasons.
we talked about them vyshe.Tak what to do, what to do?
This article is just meant to drywall on the wooden ceiling was carried out correctly, taking into account all the specific characteristics of the wooden structure.
basic rules for installation of GCR in a wooden house
little deviate from the topic.
If you plan to hold drywall coating not only at the ceiling, and walls, it is important to consider one small, but very important detail:
- mounting frame is carried out first on the ceiling and then the walls (sm.Karkas ceiling plasterboard- all the little things or little things do not happen.).
- In no case should not be connected together frame the ceiling and walls.Between them there must be a gap.
Our information - if you're worried that the gap between the walls and the ceiling will spoil the look of your home, it is quite wrong.
There is a wide variety of ceiling moldings, that can be used to cover the gap.In this case, a plinth mounting should also be performed on only one surface, the ceiling or wall.
meet this condition, you will provide sufficient space for shrinkage of wooden structures with no apparent impact on the external topcoat. As you can see the rules are simple, but their implementation will avoid major problems in the future.
Plasterboard and wood - correct installation
Now let us consider in detail the whole process:
- As in any other case, installing plasterboard coating, it all starts with the installation of the profile, carcass.
- note immediately attach it to the wooden structures must use the screws and in any case not nails.Screws have good holding power and perfectly included in the tree.
Our advice - if you buy screws pay attention to their destination.There are screws for metal, wood dowel.
- installation begins, as in any other case, to determine the lowest point on the existing ceiling.
- In determining this point on the wooden ceiling, take this issue most closely.
- Unlike concrete structures, wooden elements may have differences of height in several places.
How to define these terms, we will not tell, this procedure is described in some detail in our pages.
Circumstances demand that we again avoided the topic.
fact that arranging the ceiling in a wooden house should pay attention to the unit of the overlap.If you have an almost flat floor covered with boards this one case, but if you are in an overlapping beams is quite another.
In the beginning, we will consider with exposed beams.Why are we doing this?
Everything must be rationally
Such a position is quite clear, if we are talking about the device ceiling coverings in a new home.Agree, it is unreasonable to hold the rough ceiling boards when you are going to install subsequently coating GCR .
It is simply not sustainable and will lead to excess cost overruns.Of course, if the installation of the GCR made in the old, already a building, it is quite another matter.
Crate - proper fastening
- With a beam, you can certainly install on their frame made of metal profiles, but in this case you later encounter a problem installing insulation.
- Another important point is the distance between the beams.Depending on the size and span beams, this distance may vary between 500 mm and above.
In any case, the size is not suitable for fastening sheets GCR .
- Therefore, before installation, you must mount a crate of timber 30x40 , which subsequently will form the insulation.
- Fits across beams supporting beams at a distance 300 - 400 mm apart.
Before you perform installation of lathing, using staple gun, to shoot the joists vapor barrier.
device for frame we need:
- Profile CD (PP) profile ceiling.
- Profile UD (PN) Profile guide
- Connectors single-level (Crab)
drawings - the right decision
Unlike conventional installation of the GCR, plasterboard ceiling in a wooden house begin to get directly to the installation of hangers.So
- Earlier we talked about the fact that the ceiling mount to the walls of the FCL can not.
- If we set around the perimeter of the profile UD, while shrinking the design we can not avoid problems.
Just because suspensions are not set out, quite difficult to correctly place the hangers in the right places.
Therefore, proceed as follows:
- Perform ceiling drawing room to scale.
- shown on the drawings the exact location of a log ceiling beams and purlins.
- Knowing the size of the sheet of the GCR, to properly place the profile in the drawing.
distance accommodation profile we described and will not be repeated.
- According to these data, mark up the location of the hangers.
Mounting frame - basic features
can only tie hangers, strictly following the drawing.
important - remember, UD profile is not attached to the wall is not not the ceiling, it is fixed directly on a CD profile.Therefore, the presence of the suspension on the edge of each profile CD required.
Then begins the installation frame:
- attached to the suspension profile CD.With the construction level, observe the location profiles on the horizon and each other.
- Regardless of the size of the sheet GCR profile should be placed on the two opposite edges of the ceiling.The gap between the profile and the wall must be at least 10 mm
- further from the end of profile CD set profile UD.This fixation is carried out directly on the profile CD.
- Using single-level connectors (crabs), set cross the bridge.
distance at which they are to be installed, we have described, simply repeat at every junction of GCR sheet have to be a jumper or a longitudinal profile.However, they must be placed exactly in the center seam.
Our reference - Many people wonder whether it is possible to use only timber frame?The answer may be, but it is advisable to use a special profile in terms of durability, reliability and convenience.
And the price for these products is low.
frame is ready, you need to install directly the GCR.Instructions on this issue is described in detail on our website, so we will touch on another matter.
Gain - wrong decision
Many people wonder how to fix plasterboard to the wooden ceiling, if he is at once the floor of the second floor?
not an idle question, and quite understandable.In case of insufficient rigidity of floor beams, floor, he's ceiling sags under the weight located on the second floor of furniture and living in the house.
This question will be discussed later, but now let's talk here about what:
- Sometimes, after you install the bad Dried lag occurs deformation as the drying .
- many tips to prevent this circumstance, before installing ceiling GCR fully sheathing board to fix the lag overlap.
- At the council we want to say the following, this recommendation does not lead to the desired result and a bad drying boards themselves for even greater deformation and cracking the ceiling seams GCR.
possible to avoid these consequences?You can, if used for the lag floors, well-dried wood, but we offer you a slightly different way.
«Sliding» ceiling - mounting hanger features
It is worth noting that our proposed method is also well suited for the coating of the FCL device for walls of wooden houses, where the drawdown can be up to 100 mm.In this case, one can not do the cracks, breaking drywall software.So
- method lies in the special mounting hangers.
- They do not just rigidly secured to wooden structures, and have a certain progress in the parties reaching 10 - 15 mm.
- This is achieved through the use of sliding supports to the rafters.
- Thus, profile CD has a free movement, providing the ability to resist deformation around the frame of wooden structures.
- tree, mixed, and the frame together with GCR remains in place.
Materials for the installation of the sliding frame
for devices of this framework we need:
- Profile CD
- Profile UD
- Connectors single-level (Crab)
- Closed sliding support for the rafters
sliding bracket - the first step
Before installing hangers must perform some training sliding mounting.
- On-site suspension fasten sliding support.
- put through her suspension.
- Now you can set the profile to its place.
- In this connection, the suspension slides inside a sliding bearing on the axes.
- motion of individual beams overlap, is not reflected in the overall design of the ceiling.
- No preconditions for the formation of tension in some parts of the carcass.As a result, cracks and deformations, despite the considerable shrinkage of the wooden parts of the house.
Crab and sliding suspension
This is what we looked at how to arrange without suspension is transverse.
- When you need to establish a similar structure in the place of installation of single-level connectors, everything is repeated with the exception that in addition to the suspension attached crab.
- Arranging such a design, try to mount the bracket in such a way that the length of the suspension was as short as possible.
In any case, such a construction is very reliable and durable.
Fancy - the right device seams
Now it's time to talk about possible cracks were formed due to the deflection of the load beams sverhu.Dannaya situation is possible when applying the ceiling of the GCR in houses with rooms arranged in two tiers.
These fears are completely unfounded. Usually joists overlap are arranged in such a way and have such a cross section that a strong deflection is practically excluded.
If you are afraid of this situation, we recommend that you do the following:
- After the sheets of drywall installed, the time comes to putty joints joints of individual sheets.
- With Knife Adv carpentry joints so that their outer width of 5 mm , the angle of the bevel on both sides, was about 45 - 50 degrees .
- for spackling not use plastic putty type.Purchase can be in any specialty store.Using reinforcing
- serpyanka necessary.
If you do all the instructions, your ceiling will not be afraid of any external and internal influences on his frame.For this wooden house it is very important.
