The semicircular arched doorway ennobles and helps create comfort in the apartment. In choosing the material for the manufacture of arches often prefer plasterboard.

Before starting work, create a sketch of the arch. This will help to calculate the amount of material. Form of the arch depends on the width and height of the door opening:

The classic version - Dome Arch. Such arch radius equal to half the width of the opening. Classical arches suitable for registration apertures height more than 2.2 m and a width of 100 cm.
Asymmetric arches or poluarki look good in narrow doorways.
Arch Art Nouveau - symmetrical arch with a radius exceeding the width of the opening half.
Romantic style arches suitable for wide openings. In this case, the upper portion of the opening is straight, only the corners are closed
Design or delicate arches do not have a strict form. Mounted at the device plasterboard partitions for separating space into zones.

Fastening elements for cardboard-gypsum arches frame required. Use of metal sheets for these purposes, possibly with the wall thickness of the door opening is not less than 9 cm. If the slope is less than the width, for the frame using manufacturing wooden beams or rails, which is undesirable. In this case, give preference to the wooden door arch.

Prosekatel for connecting profile planer for plasterboard, a laser level to help get the job done quickly and efficiently. Well, if you have such tools. But buy them for mounting one arch does not make sense.

When installing the arches advise to use 9-12 mm thick for the main part of the GLC, the arched plasterboard with a thickness of 6.5 mm. It is impractical for the sake of a small strip buy a whole sheet of material. The Arch itself performs only a decorative function, its surface is not subjected to mechanical loads. It is permissible to use GLC 6.5 mm or 9 mm for the entire design.

For the device arches with the width of the doorway to 100 cm you will need:

plasterboard 6.5 or 9 mm - 1 sheet;
profile ceiling PN 28/27;
profile guide PP - 60/27;
self-tapping screw;
dowel-nails;
sealing tape;
cable for mounting wiring and installing point lamps;
for further finishes, the finished design requires primer, putty, perforated corners, srupyanka, grinding grid.

Procedure for conducting work:

preparation of the opening of the arch;
creating a sketch of arches and cutting plasterboard;
installation of frame arch;
installation of the cable if the installation of point lamps is planned;
fastening of plasterboard;
installation of arched protective corners and plasterboard shtlock;
final finishing, installation of lamps.

To prepare the opening, dismantle the door frame. In case of strong damage, align the plastering mixture. Make the front of the arch. To do this, cut the sheet of plasterboard, respectively, in width and height of the arch. The contour of the symmetric arch is convenient to draw with the help of a pencil and fishing line. To draw a symmetrical arc, Use simple devices. Next, cut the sheet with a knife on the planned line. For the cutting of the GLC, the electrolovka is used rarely - the small teeth of the jigsaw feeder are quickly blinking during the processing of plaster.

To create a frame fasten the guides in the upper part of the opening. The length of horizontal guides must correspond to the height of the arch. The profile is attached to the thickness of the plasterboard. The edge of the profile is located at a distance of 9 mm from the wall plane. To give the profile the shape of the arc, cut it with a shelf with scissors for metal or a grinder every 4-5 cm. Cut the length for an arc to a reserve at 20-30 cm - easier then to remove more superfluous than trying to put the missing profile.

Mounting frame:

With the help of dowels, lock the ceiling profile on the ends.
To ensure noise insulation, before the start of installation on the profile, the DichunSbad sealing tape is glued.
Next, install a short rack profile in the center of the arch. The rack profile is attached to the guide with small tapes or a bug.
Secure arcs for arches from a bent arched profile (marking PN 27/28).
Secure the design with a racking profile and suspension.

Facing a frame of plasterboard is performed in the following sequence:

Cut the frame on both sides of the cooked sheets.
Cut the lane of plasterboard in the width of the arch. In length, it can also be more arc by 15-20 cm.
Ride the strip needle roller.
Moisten water with a brush, give water to absorb.
The wet bar of plasterboard has sufficient flexibility, which makes it possible to fix it in an arc.
After stripping the edges of the sheet, the plane can begin to decorate the arch.
