Door box and its self-assembly

Bought a new door and decided to install it yourself? No problem. Let's figure out how to assemble and install the door frame with your own hands.

First lay all the parts of the door frame on the floor. Build the door stop, connect it to the top and right strapping (side), and then just connect it to the top and left. Next, you need to nail the bar (section 5 by 2.5 centimeters). It needs to be done exactly between the two straps at the sides, located at the bottom of the door frame, so that the straps do not move and are parallel during the whole process of installing the door.

In front of you the assembled door frame. It is necessary to install it in the doorway. Make sure that it is exactly in the center. It is not superfluous to verify the verticality of the installation, as well as the perpendicularity of the elements and the horizontality of the upper strapping.

Next, the door frame will be attached to the wall. It is necessary to put a piece of plywood on the box itself. Do this only in those places where it touches the wall. After this, you must again check the verticality of the side parts. Find reinforcing bars, the door frame should be attached to them, use nails without hats, if you have a wooden wall, or screws, if you have a stone wall. Next, remove the bar, which was nailed, and again check the horizontal of the upper strapping. If there is any displacement, correct it. The door frame is ready.

Now we need to disassemble the hinges. How to do it? Take out the axes from them, and then screw the corresponding parts of the loops into special grooves, which must be cut out in the door. Place under the door of the lining and install it in the box. Adjust the locking bar if the door does not close smoothly.

Then over the door you need to install the platbands (top element). Attach the element to the wall, make sure its levelness is horizontal and nail it with a nail (distance - about 7.4 centimeters from the corner). Then nail the other nail on the opposite side (the distance from the corner is the same). Nails need to be hammered at a distance of 15 centimeters from each other.

Lateral elements should also be nailed. There should be no slots, adjust everything to within a millimeter. After making sure of accuracy, nail the side elements on the other side of the door.

To cover the various gaps between the wall and the box, as well as for decoration, use the exterior and interior trim. The exterior is always more massive and beautiful. They are usually made from spruce or pine pine (thickness from 20 to 30 centimeters), less often from linden.

As for the internal platbands, they usually have a width of 7.5 to 15 centimeters. They should be a bit wider than the bars of the box (2-5 centimeters).

The front part of the platbands can be of various shapes, and on the inside they have grooves, the depth of which does not exceed five millimeters. These grooves will ensure a tight connection of the clypees with the box and with the wall. In the corners, you need to connect the platbands at an angle of 45 degrees. Pay attention to this point, you need to dock everything very accurately, so that there are no cracks, otherwise eventually eventually get a big hole between the pieces of platbands.

The platbands are fastened, again, with the help of nails (choose nails with flattened heads). Drive the nails at a distance of 50-70 centimeters from each other.

The installation of a door frame with a chimney requires additional bars. The fitting is necessary when the thickness of the door frame is less than the thickness of the wall. You can use the device for aesthetic reasons.

Assembling the door frame with your own hands is finished.
