Whatever building is built, the installation of doors takes a lot of time and money. To save on this, you can put the door box with your own hands. In this case, the installation process will be controlled personally by you. In addition, the implementation of such work helps develop accuracy, as well as learn a lot of new in building codes. It should be said that the durability, strength and aesthetic appearance of the door largely depends on the quality of the door frame installation. Therefore, this stage of work should be taken with special responsibility. Next, we describe how the installation of the door frame.

Door box: dimensions

Dimensions of the door wooden box are determined by several parameters:

  • First - the dimensions of the selectedfor the door leaf box.
  • The second - the purpose and characteristics of the room.

Before starting work, read the instructions on how to assemble the door frame. It is necessary to say that different rooms have different requirements for ventilation and noise insulation, and they, of course, should provide the installed door. So, for example, the door to the bathroom should not let in cold air and at the same time, do not let warm air leak out. Other rooms, for example, storage rooms, on the contrary, need ventilation so that the materials inside are not spoiled. If the door is installed in the boiler room, it will be superfluous to make additional ventilation, especially if there is gas equipment.

To prevent heat loss, the construction of the door frame is built from four bars. As a result, it will be a closed rectangle in shape. In this case, in the design of the door itself, there will be such details as a feigned and vertical vertical bar, as well as lintels. Between the beam of the box and the door all along the perimeter it is necessary to maintain a clearance of 3 mm so that the door can move freely.

If necessary, the duct is assembled in only three parts. In this case, instead of the threshold, a technological gap of 16-18 mm is left. The door base will then have the shape of a letter P. At the same time, the necessary indentation of 3 mm must be observed only along the upper timber and vertical posts. In addition, between the threshold and the new floor covering, a gap of 2.5-3.5 mm must be observed to compensate for the expansion of the material at a temperature drop.

A closed box is usually larger in height than an unclosed one. This is due to the fact that the height increases due to the thickness of the threshold, and, consequently, the thickness of the door frame will be greater. This must be taken into account when carrying out calculations and measurements. Otherwise, the door will be too long and it will have to be shortened to fit under the opening. This is extremely undesirable to do, especially if the fabric has a veneer coating. If you have to cut a similar coating, start best on the side where there is a decorative finish, and then move to the side where this finish is not. In this case, the construction of the box will not be broken.

To replace the door frame with your own hands, you will need some tools:

  • So, you will need several bars that usually come already complete with the door frame itself.
  • To prevent misalignment during installation, you need to have a plumb line or level at hand.
  • In addition, you will need nails, a hammer, a screwdriver with screws, an electric fryer and a hacksaw.
  • For the work, you will need wooden slats, a router, chisel, mounting foam, and as wedges you can take trimming.

Of course, a set of professional tools will be quite expensive, but this will ensure a high-quality result of the work. The fact is that when using simple tools for mounting a box, it is possible to admit large errors, especially if there is little experience in this matter. Therefore, before starting work, you should contact specialists who can give high-quality tools for hire. It will be much more profitable, becauseThere is no point in buying new devices for one job.

Before you put a new box, you need to dismantle the old one. This item is a key part of the preparatory phase. This is quite simple:

  1. First you need to remove the trim, then take a hacksaw and a mounting tool, with which you remove the entire old wooden box. It is very important not to damage the wall, which can be a waste of time in carrying out additional work on the finish.
  2. The old anchor bolts and the remaining fasteners are twisted or, as an option, cut down with a grinder. Be sure to check the strength of the wall. If necessary, the pressure-extinguished door frame should be reinforced.
  3. When removing the old box, firstly the trim is removed. Then, through the hacksaw, the box itself is dismantled.
  4. In order to strengthen the wall, sometimes it is necessary to install a reinforcement structure. This is a very important point, becauseit depends on it how much the installed door will serve.

Assembly steps

The assembly work consists of several steps:

  • First you need to measure the doorway. After dismantling the old box, its dimensions may differ from the original one. The results of measurements are necessary in order to be able to put in place spacer wedges, the dimensions of which should exceed the distance between the beam and the wall by no more than 3.5 mm. Anyway, with them the fastening of the box will get stronger. It should also be noted that the presence of a swivel chair allows, where necessary, to score the beams at an angle of 45 degrees. Therefore, before carrying out installation work, be sure to purchase a similar tool.

  • So, let's start assembling. The work is conventionally divided into several stages, the first of which is that the bars of the structure are simply laid out on a flat surface where they can be easily inspected. In this case, it is necessary to pay attention to the presence or absence of grooves in the boards, by means of which the parts will be joined in one piece.
  • It is very important to properly fix the installed box. To do this, holes are drilled in the joints of the bars. Planks, located horizontally and vertically, need to be pulled off by screws. The most important thing is to be neat and accurate. To do this work correctly is to ensure sufficient strength of the door fastening. Note that in some modern door systems that do today, the lower bars are not available, because, in fact, they do not need.
  • If there are grooves, then they are connected to the sides of the other bar in the upper part of the bar, and they are accurately knocked down using a wooden kayak. It is better not to use the other tool so that the material is not damaged.
  • Then all the parts join together. Screws are suitable as fasteners. When this is done, you need to check how reliable the resulting design has turned out. A short beam of grooves may well not be. Then choose one of two options: the parts are fastened with nails or screws. This completes the first stage of the assembly.
  • The protruding ends of the wooden beams will interfere with further work. Therefore, with their sawing, the second stage of installation begins. Next, before you continue working, pay attention to the surface of the bars. If it is smooth and smooth, it means that everything was done correctly. Also you need to take measurements from the top of the door frame.
  • In addition to the surface, be sure to check how straight the corners of the structure have turned out. Then the rake is cut off, and then fixed by means of nails to the side rails. The excess parts of the slats should be cut off. This concludes the second stage.
  • In the third stage, door hinges are installed in place. To do this, the door and the door are assembled on the floor in the assembled state. In this position, you need to determine the location of the loops. Note that there must be at least 19 cm between the top and bottom edges of the door. The length can be different. Most importantly, on all doors of the house it was about the same.

  • The contours of the hinges are marked at the right place, not only on the door, but also on the door frame. When the door is in place, there should be a small gap between the floor and the top. Next, you should check out some important points. For example, the horizontal and vertical axes of the door frame and the door leaf elements must match.
  • We proceed to trim the seats for future loops. This requires a chisel. So, on the inside of the design you need to measure from the top edge of 19 cm. Then a door hinge is applied and outlined along the contour with a simple pencil. It should be taken into account that the folded loop from the door to the box leaves a gap of about 40 mm. Taking into account the thickness of the loop, it is necessary to calculate the depth of its installation.
  • Then take the router and prepare the seat for the upper and lower loops. If there is no milling cutter, then, as mentioned above, you can dispense with a set of chisels. From the bottom edge of the door structure should be an indentation of about 22 cm, with 10 mm of which are removed under the clearance from below.
  • Then the box together with the hinges is applied to the door leaf. This is necessary in order to make the door marking places for fastening loops. On the door leaf the cutouts are made the same way as on the door frame.
  • Further measurements of the dimensions of the opening are made. The obtained results of the calculations are transferred to the side bars. When this is done, the box can be lifted gently and proceed to install it in the doorway. With a plumb or building level, be sure to check the verticality of the structure. In addition, you need to make sure that the angles are straight, and the top bar is strictly horizontal.
  • There is always a possibility that the frame from the first time does not fit into the opening. This can happen even if all measurements were made without errors. If there are such shortcomings, do not worry. The gaps between the box and the opening are easily sealed with a mounting foam.
  • When the frame is in place, it is necessary to fix it. To the slopes the box is attached by dowels. As a result of the work, the structure in the opening must be secure. This must be checked before the temporary laths and struts are removed. After this check, the temporary parts are removed, and the protruding parts of the wooden wedges are sawn off.
  • With gaps, the accepted standards must be observed, which can also be easily calculated independently. When using mounting foam during the work, do not forget that it expands when it hardens. Therefore, there should be an opportunity to cut off unnecessary without obstacles. It is important that the used fasteners and hinges fit under the weight and purpose of the door. When performing the installation of the door frame, one should not forget about the microclimate in the room.

This completes the installation of the structure. Therefore, you can hang on the hinges of the door and install the platbands. Casing can be fixed in various ways. For example, on nails, on self-tapping screws or on glue. If nails were used, their hats should be closed after work. In the case of using self-tapping screws, they should be worn with decorative plastic plugs. In the same way, metal door frames are assembled.

Features of the door frame assembly for houses and saunas from the timber

Undoubtedly, wood is one of the best building materials. But it has one feature, which should be remembered - after the construction after a while it settles. Therefore, for wooden houses it is not recommended to equip doorways after erecting a crown about a couple of years. It is all the more necessary to know how to properly put the door frame in similar structures.

Basically, the following method is used. So, if the dimensions of the opening and the width of the door frame are the same as the dimensions indicated in the project, then at the end, a groove is cut right in the middle and then a bar is jammed into it, to which you can nail the box. The walls, even after shrinkage, continue to settle. Therefore, you can not attach a box directly to them. If the opening is not yet formed, then first of all an opening is made for the door structure. And the width of this passage should be two thicknesses of the ridge less than indicated in the plan. In this case, the box beam is made with a groove. Next, the box is installed according to the same scheme as described above.
