Have you 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.
To begin, lay on the floor all parts of the door frame. Build the 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 strands located at the bottom of the door frame, so that the strands do not move and are parallel during the entire door installation process.
Before you assembled door frame. It is necessary to install it in the doorway. Make sure it is centered. It will also be useful to check the verticality of the installation, as well as the perpendicularity of the elements and the horizontalness of the upper strapping.
Next, the door frame will be attached to the wall. You need to put a piece of plywood on the box itself. This must be done only in those places where she touches the wall. After this, you must again check the verticality of the side parts. Find reinforcing beams, the door frame must 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 any bias occurs, correct it. The door frame is ready.
Now you need to disassemble the loop. How to do it? Remove the axles from them, and then screw the corresponding parts of the hinges into the special recesses that must be cut in the door. Place linings under the door and install it in the box. Adjust the locking bar if the door does not close smoothly.
Then, above the door you need to install platbands (top element). Attach the element to the wall, make sure it is level and level with a nail (the distance is about 7.4 centimeters from the corner). Next, nail another nail on the opposite side (the distance from the corner is the same). Nails must be hammered at a distance of 15 centimeters from each other.
Side elements should also be nailed. There should be no gaps, fit everything to the nearest millimeter. After ensuring 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 outer and inner platbands. The outdoor ones are always more massive and beautiful. They are usually made of spruce or pine wood (thickness from 20 to 30 centimeters), less often from linden.
As for the inner platbands, they are usually wide from 7.5 to 15 centimeters. They should be slightly wider than the bars of the box (2-5 centimeters).
The front part of the platbands can be of various shapes, but on the inside they have grooves whose depth does not exceed five millimeters. These grooves will provide 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 attention to this moment, you need to dock everything very accurately so that there are no gaps, otherwise in the end you will eventually get a big hole between the parts of the platbands.
Platbands are fastened, again, using nails (choose nails with flattened heads). Drive nails at a distance of 50-70 centimeters from each other.
Installing a door frame with an extension requires additional bars. Extraction is necessary if the thickness of the door frame is less than the thickness of the wall. You can use the extension for aesthetic reasons.
Do-it-yourself door frame assembly is complete.
