The installation of the wall combines the technology of fixing ceilings and partitions. In order to make a false wall, you will need the details of the frame, such as ceiling hangers and crab connectors, and rack-mount profiles. But there are still some differences, drywall should be taken thicker, fastened more often and double-layered installation of drywall can not be avoided for the rigidity of the structure.
Plasterboard walls are also used for the construction of concealing structures on the wall, behind which it is possible to place pipelines, electrical wiring and other communications. Designs on the wall allow you to arrange niches and other decorative elements of the interior.
The gypsum wall covering with facing of masonry and concrete slabs can be carried out on a skeleton base or directly on the surface of the walls. Fastening of sheets with their own hands directly to the surface of the walls is done using gypsum adhesive glue mixtures. Drywall, with facing of wall structures, apply standard sizes, sheet thickness is recommended not less than 12.5 mm. The basis for the installation of drywall should be strong, dry, do not crumble, Do not deform, do not expose to moisture, do not freeze and collect condensate. Installation of gypsum boards on the wall with the help of glue gypsum solutions is not allowed on raw cement plaster.
Before you begin the fastening, you need to treat the base with a primer to increase the adhesion of the adhesive mixture to the wall. The ready-made glutinous mixture should be evenly distributed on the inner side and putting the sheet to the base to press over the entire area. The joints of the sheets are leveled, tapping with a rubber mallet. Installation is made so that there is a gap between the sheet and the floor - 1 cm, ceiling - 5 mm. This is necessary for the adhesive solution to dry.
Fastening on a skeleton from metal profiles uses
more popular than glue solutions.
The frame for facing wall structures with plasterboard is made of standard parts and profile. Decorative niches and other forms of plasterboard wall designs, decorating the interior, should To be reflected in the construction of the frame, on which the installation is performed.
Installation is carried out using the rack profiles and moisture resistant drywall, by a two-layer method to strengthen the structure and prevent the appearance of cracks in the joints. Walls made of drywall are effective in use on walls that can freeze or be cold, thereby preventing the formation of mold and insulating the apartment.
Ceiling guides need fixed to the base by straight hangers, while you need to make sure that the plane is formed straight and vertical, it is important to check the presence of the collapse of right angles of adjacent walls. They must have a right angle. To determine the presence of camber in the corners, You can perform a simple operation to measure the distance between opposite corners of the room. If the distances are the same, then all angles at you are direct under 90 degrees, and if distances on diagonals different, it will be a rhombus, to correct it On a square it is possible to fit the frame under the plasterboard. A large structure must be mounted on a sturdy frame. For a reliable The three-dimensional framework uses rack-shaped profiles, starting guides of the corresponding width. For non-principal non-carriers elements of the frame can be used ceiling guides and starting profiles. The frame on which the wall stands should be reliable fasten with screws, screws or even if necessary, rivets and threaded hardware. In such a vertical structure, drywall should not carry any serious loads, for this It is necessary to provide additional bulkheads from the profile in the frame. Screws in metal profiles need to be screwed with a screwdriver, since on the screwdriver there is an adjustable force device, so that the screws are normally tightened and do not break from the thread.
The use of a drill with a special bit when twisting the screws is not desirable, since the inertia of the drill chuck is very large and calculate the effort with which you need to press self-tapping screws, it will be very difficult. Also when constructing the frame structure It is necessary to provide "windows" for fastening switches and sockets. When using special plastic podrozetnikov for gypsum cardboard it will be necessary to simply very accurately cut perfectly smooth holes along the diameter of the podrozetnik in gypsum cardboard, better all this done with a special bit or drill to drill the pits under the podrozetniki, they are used for both brick and plasterboard. If you want to make a reliable attachment of the podrozetnik, then you need to glue the pieces of plasterboard from the inside in such quantity that the podzroetnik on the ends is completely is clamped in a drywall sheet, and it is also necessary to close the hole by applying another whole piece of gypsum board with a small hole for cable entry so that the juniper fits completely into the pit. The podzroetnik can be strengthened in the pit by a thick layer of liquid nails. For circuit breakers, the requirements may be less stringent in strength, since the load on the switch is minimal. In order to avoid the spillage of the core of the drywall at the site of installation of the juniper, it is necessary to soak and dry the butt ends of gypsum cores deeply penetrating primer.
To the picture was finished, it is placed in a frame. If we imagine our windows and doors not just openings to the outside world, we make installation of slopes from plasterboard, which serve as a means of harmonious flow of the portal into the interior.
The main condition for the execution of window and door slopes is thermal insulation. It is the slopes that make the main thermal barrier in the connection of the window frame to the wall of the house. If this condition is not taken into account and the qualitative execution of the slopes is neglected, then with the onset of cold weather, one can face such negative phenomena on the slopes and in the corners windows like mold and water condensation. Modern windows have sufficient tightness and thermal insulation, so when installing windows is the task of only qualitative finishing slopes.
Modern technology of finishing slopes involves the use of drywall. Drywall gives strength, thermal stability and ease of installation. Drywall is tightly mounted to the frame of the window or door and at the finish makes a strong angle, as well as when plastering slopes. If the slope of the plasterboard is painted with glossy acrylic paint, then it will be much better than plastic.
Slopes of plasterboard are made frameless method from moisture resistant gypsum board, planting on polyurethane foam.
Drywall should fit tightly and without cracks to the frame, so you need to thoroughly clean the foam from the frame to the above The depth along the entire perimeter of the frame.
The openings (window and door) in most cases have a characteristic shape with an expansion, so the drywall will be have a trapezoidal shape.
Measurements are made along the existing opening in three planes. The first figure shows a window opening, where 1 and 2 are the slope planes. It is necessary to measure the dimensions of the plane 1. To do this, measure the width from the edge of the frame to the outer corner of the wall, the length at the edge of the wall and the length outer edge of the frame. Thus, we obtain the dimensions of the trapezoid for the workpiece 1.
On a drywall sheet, draw a trapezoid on the resulting dimensions, plus at the base, add 1 cm of height for the workpiece to enter the groove. That is, if the real width of the opening in the plane is 1 to 35 cm, then the workpiece will be width 36 cm. Then we cut drywall on the planned lines. The top slope must be set first, since The dimensions of the other two will be taken from the established upper slope.
Installation of slopes from plasterboard can be done with polyurethane foam. On the workpiece, foam is applied with small rollers.
