The door frame is called a frame consisting of bars with folds. How to make a box is not easy to describe in a nutshell. Yes, and its installation is no less difficult.
The door frame is fixed with spacer dowels or steel plates. To avoid distortions when installing the door frame, you must use a plumb line or level. If the walls of the building are stone, then the boxes are fixed to wooden plugs with nails. If the walls of the building are made of slabs, then the boxes are fixed with staples.
How to make a door frame? For this, boards up to 60 mm thick are used. Depending on the thickness of the walls, choose the width of the board. The width of the box itself for one door should not exceed 1 meter. If you decide to install double doors, then the width can be up to 3 meters.
If you make a box with a threshold, you will need four wooden blocks. A vertical bar is called a slope, and a horizontal bar is called a support. The upper horizontal bar is considered to be a door lintel. The slopes should overlap with horizontals by approximately 10 cm. This ledge is cut off at 45 degrees and is called the head. How to dobox? First of all, this is a very technological process.
The choice of material, its further drying and processing are all links in one technological chain. The bars are carefully processed, then, depending on the thickness of the canvas, its dimensions are selected.
1. Assembling the box. Before installation, the top and side straps are assembled, after which you need to proceed with the installation of the box in the doorway. Place all three parts of the door frame to be assembled on the floor. Using 75mm nails, nail the connected top and right side rails to the pre-installed door stop. As a rule, there should be a gap of at least 2 cm between the box and the wall. It will later serve as thermal insulation. Due to the gap, the installation process of the box will be less difficult, because the horizontal and vertical surfaces will be installed correctly. Install the top and left straps in the same way. Nail a plank between parallel slopes measuring 50 x 25mm so that during the installation of the doors they remain parallel. And the question of how to make a box becomes irrelevant.
2. Installation. In the doorway, install the box and carefully place it in the center. After that, it is necessary to check the levels of perpendicularity and verticality of the installed elements. Using a level, plumb line and square, also check the level of the upper trim. If necessary, install the seal. For proper fixing of the box, it is necessary in places where ittouches the wall, place any seal under it. After that, it is necessary to re-check the perpendicularity of the side elements. If the wall is stone, then fix the box to the reinforcing bars with 65 mm capless nails. Then remove the nailed bar and recheck the level of the top trim. Correct if necessary. Thus, we managed to answer the question of how to make a box to the fullest.
