Bought a new door and decided to install it yourself? No problem. Let's figure out how to assemble and install a door frame with your own hands.
First, lay all parts of the door frame on the floor. Build a door stop, connect it to the top and right trim (side), and then connect it to the top and left in the same way. Next, you need to nail the bar (section 5 by 2.5 centimeters). This must be done exactly between the two side straps located at the bottom of the door frame, so that the straps do not move and are parallel during the entire door installation process.
Before you assembled the door frame. It needs to be installed in a doorway. Make sure it is exactly in the center. It would also be useful to check the verticality of the installation, as well as the perpendicularity of the elements and the horizontality of the upper trim.
Next, the door frame will be attached to the wall. It is necessary to put a piece of plywood on the box itself. This should be done only in those places where it touches the wall. After that, you need to check the verticality of the side parts again. Find reinforcerstimbers, 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 that was nailed, and again check the horizontal of the upper trim. If there is any misalignment, correct it. The door frame is ready.
Now you need to disassemble the hinges. How to do it? Remove the axles from them, and then screw the corresponding parts of the hinges into the special recesses to be cut into the door. Put lining under the door and install it in the box. Adjust the lock bar if the door does not close smoothly.
Then you need to install platbands (top element) above the door. Attach the element to the wall, make sure it is level and nail it with a nail (distance - about 7.4 centimeters from the corner). Next, nail another nail on the opposite side (the distance from the corner is the same). Nails should be hammered at a distance of 15 centimeters from each other.
Side elements should also be nailed. There should be no gaps, adjust everything to the nearest millimeter. Once you're sure it's accurate, nail the side pieces on the other side of the door.
To close the various gaps between the wall and the box, as well as for decoration, use the outer and inner trim. Outdoor ones are always more massive and beautiful. They are usually made of spruce or pine wood (thickness from 20 to 30centimeters), less often from linden.
As for the inner casings, they are usually 7.5 to 15 centimeters wide. They should be slightly wider than the box bars (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 platbands with the box and with the wall. In the corners you need to connect the platbands at an angle of 45 degrees. Pay your attention to this moment, you need to dock everything very accurately so that there are no gaps, otherwise you will end up with a big hole between the parts of the platbands over time.
The platbands are attached, again, with nails (choose nails with flattened heads). Drive in nails at a distance of 50-70 centimeters from each other.
Installation of a door frame with an extension requires additional bars. Dobor is necessary in the case when the thickness of the door frame is less than the thickness of the wall. You can use the add-on for aesthetic reasons.
