We make the frame for gypsum cardboard correctly

With gypsum cardboard sheets you can build complex transitions on the ceiling, niches in walls, arches, shelves and so on. Much popularity is simply the lining of walls with plasterboard without the use of a frame. That allows you to get a perfectly flat surface even on very crooked grounds. But if the deviation is within 4 cm, it will be necessary to coat the walls with gypsum boards on a metal frame.

Types of materials for building a frame for gypsum board

There are 3 types of materials for building a frame for gypsum board:

1. Metal profile. This type is most common due to the convenience of working with flexible metal, the ease of the finished structure and ease of installation.
2. Wooden frame for drywall. It is used in the smallest cases due to the properties of the wood itself. First, it is prone to rotting when it gets wet or permanently moist. Secondly, over time it dries, which leads to a change in its geometric parameters. And in the end, this will affect the geometry of the most finished structure, corners will be cracked, putty will begin to chip off and so on.
3. Combined. It is more common, because the whole frame for gypsum board is made exclusively of metal, and in places where the load is increased on the wall( furniture or equipment), a wooden block is put in the profile.

Types of profile for building a frame for gypsum board

The choice of the profile type for gypsum board is based on the geometric parameters and the necessary strength of the future structure. It can be a decorative column or an imitation fireplace in the wall, then you can apply a profile under the drywall of a smaller thickness and width. Thus saving a certain amount of money and time. But if it is a niche, an arch, some protrusions, which are not only an ornament of the interior of the room, but also its functional elements. That material should be chosen thicker, fasteners should be carried out more thickly.

Today, there are several types of metal profiles in geometric parameters and type of production, from which it is possible to mount a frame for plasterboard on walls:

1. Guide profile. It is a groove curved on a rolling mill in the shape of a letter P or U. Accordingly, it can be named PN or UW.It is used for fixing the bases of structures to walls and ceilings. Its main property is that it has a proportional width, allowing it to freely insert the rack-mount profile. After all, any installation of the profile under gypsum cardboard on the walls requires special strength and quality of joining the elements. And the dense occurrence of UW in CW just provides that necessary quality.
2. Rack profile, having the abbreviation CW.Designed to perform vertical elements of any design. It has a high bending strength due to its special rolling technology. If you look at the cut, you can see the rounded edges and additional bends on its flat surface. This provides him with additional strength, unlike UW.The frame from the profile for gypsum cardboard on the wall due to compliance with the technology must have high strength, stability, and with the correct placement of the stiffeners is not subject to vibrations.

Required materials for the construction of the

gypsum board Before you begin installing the frame under the plasterboard on the wall, you must prepare all the required consumables and accessories:

• Two types of profile.
• Wooden blocks in the thickness of the guide or rack profile. They should be put in places with increased load, also an excellent option will be its use in the doorway. Because when you open and close the doors, it usually creates a vibration. And the wooden beam at the expense of its elasticity will compensate for any types of vibration. In many cases, the structure of the frame under gypsum board does not require the use of wood. For example, a suspended ceiling, a niche in the wall with shelves and so on.
• Fastening components. These include various connectors( end and cross), brackets and hangers for mounting structures on the ceiling and loose walls.
• Hardware products. Mounting the profile under gypsum board with their own hands can not do without using a wide variety of screws, screws, ties, rivets, dowels. In this case, the screws need to have at least three types:

1. For metal. They are used for making gypsum boards fastening to the profile.
2. On wood. Used to fix the profile to the wooden wall, GKL to the frame.
3. For metal with a flat bonnet. These hardware are a means of fastening all the metal elements of the structure to each other.

Required tools for mounting

The following tools are required for mounting the structure from gypsum board profiles:

• Scissors for metal or Bulgarian;
• pliers;
• drill or screwdriver;
• a plumb line and a construction cord;
• level;
• measuring tape;
• pencil and stuff.

framework technology Before the installation of profiles for gypsum board is started, it is necessary to mark up.

So, according to a pre-designed project, the original line on the floor, ceiling or wall is applied on paper, depending on where the structure will be located. The source line is a markup element, from which you can conduct all other calculations. When applied on the floor, it becomes the edge of the front side of the sheet drywall. It must be projected onto the ceiling and walls. This can be done with a level and a plumb line. If the distances are large enough, then the construction cord will be the best assistant in this matter. Correctly applied marking allows you to make the most accurate frame from the profile under gypsum board.

After applying all the necessary marking indented into the future design, taking into account the thickness of the sheet( usually a sheet 10 mm thick, thickened 12.5 mm), the carcass installation for plasterboard can be started. About how to mount the frame will help video lesson.

First of all, you need to measure out the necessary piece of guide PI or UW-profile. This should be done as accurately as possible, but when the length is shifted by 1-2 cm, the geometry will not be affected greatly. Strengthen it with an anchor. The method depends on the type of floor covering, its structure, degree of strength. After attaching the profile to the floor, you can mount the plasterboard guides to the ceiling. Of course, after making sure of the correctness of their actions with a level or plumb.

If the floor is concrete and strong, then dowels can be used. If the base is loose and later will be leveled by the screed, it is better to use anchors or brackets of the appropriate length and diameter. When constructing a frame on the ceiling or for leveling the wall, special suspensions are used, which can also be of several types.

Next, the installation of the frame under the gypsum board continues with the mounting of the side racks, the rack profile is used accordingly. Its attachment also depends on the structure of the wall and its softness. Dowels and anchors are advisable to be used in cases with concrete or brick walls. If they are made of wood, the correct solution will be using self-tapping screws, screeds or screws. The most effective interval for fixing the rack-mount profile is 60 cm. And it depends on the future load applied to the structure. Accordingly, if it will be heavy, then it is necessary to strengthen more often.

Installation of profiles for gypsum board can be carried out according to different technologies, which depends on the complexity of the frame. After all, it can be a round arch, a protruding niche from the wall with imitation of the fireplace, many beautiful in a chaotic arrangement of shelves in niches, curved constructions on the ceiling and walls with a lot of bends and turns, complex asymmetric partitions and much more. There are a lot of options, as well as the wishes of people. But the principle should always be respected. The frame must be firm and fixed. Tricks and tips for working with a profile that will help speed up the work.

Production of semicircular frame elements

The guide for drywall allows to make a perfectly flat surface. But how to make a curvilinear bend, arc or arch? And the answer is quite simple. To curl the PN profile into the arc of its edge, it is necessary to cut it at the same distance. The smaller it is, the more smooth will be the bend. In addition, this distance also depends on the degree of roundness and radius of bending. After the cuts have been made, it is necessary to fasten the element before reinstalling it. For this idle, the side lobes folded together are self-curled.

Drywall is bent in the same way. On the one hand, a layer of cardboard is cut, and in the opposite direction it is bent to the frame.

Assembling the frame for gypsum board is a fairly simple task. In the process of work, the most important thing was marking, and its transfer from floor to ceiling. After all, the final result of all the work done depends on the degree of accuracy of this operation.

Profile mounting technologies

Installation of the profile for gypsum board can be carried out by two known technologies. The first one is American. In it, the groove profile is guided in a groove into the interior of the structure. The second, German, is the location of this gutter during the mounting of the frame. And basically the type of orientation of profiles depends on the prevailing situation and features of the design itself.

If a frame is made on a wall under gypsum board, then the rack profile is attached with hangers. Then, placing the trays in the guide rails and fixing the side racks, while aligning them using the level and plummet, pull the cord. It will be the landmark and the borderline of the touch of the middle racks of the frame. Before this, of course, all the racks need to be installed in the guide rails and slightly to press them with the petals of the hangers so that they do not fall. After the lace is tightened, each rack must be installed in place and secured with screws on both sides.
