How to properly assemble the door frame

Assembling and installing the door frame is a monotonous exercise that requires precise calculations and actions. One small mistake can cost several days of work or even purchase a new box. There are 2 main types of door frames: with or without a threshold. Recently, the second option is more popular. In addition to the slats themselves, the boxes have several holes and fasteners. The most important - the door hinges that perform the carrier function. Manufacturers have several options for boxes in terms of readiness for quick assembly and installation. The assembly itself can be of 3 main types: baguette joint, thorny (ridge) and at right angles. The second option in a broad sense implies a time-consuming and complex process, the rest leave it possible to do everything from start to finish with your own hands and without any particular difficulties. To understand how to assemble the door frame, you need to know the nuances of taking measurements, preparing parts and their fastening.

Components and equipment of the door frame

The door frame is 2 vertical beams installed on the sides of the opening. Elements are complemented by a top, attached at the top of the passage, and a threshold at the bottom. The latter may be absent due to the characteristics of the flooring or personal preference. There is an additional timber in the door frame configuration. Its task is to thicken the box, which is necessary in some situations.

On the door frame also fix the platbands to decorate and hide the flaws. To the box they are mounted with small nails with small hats, from the side of two adjacent rooms. The door frame is complemented by a slot for the tongue lock. It is made out reciprocal plate with the desired holes. The frame also includes hinges for web installation and control. In the case of a double door, slits are necessary for the lower and upper fixation of the flaps.

Material selection

It is selected based on the weight of the canvas. It is the door frame that will take all the load - from the doors and its own weight. The stability margin should be large. In the role of material, wood, micro-wood fiber (MDF boards), and metal are most often used. Preference is given mainly to the tree.

The material is popular due to such qualities as strength, naturalness, environmental friendliness, presentable appearance, ease of processing and processing. However, most of the nuances depend on the specific wood species. Boxes of interior doors are preferably made of pine. The front door frame needs to be made sturdier. Common oak is suitable as a raw material. Parts of the doorframe are also sold as ready for assembly. After their acquisition it remains only to carry out the installation.

One of the most popular materials, common oak, also has other names:

  • petiolate
  • summer;
  • English.

How to properly measure

Removing the dimensions from the door frame is done in 2 ways: by removing the dimensions of the opening and the parameters of the door leaf. In the first case 3 indicators are measured. Measure the height and width of the aisle, the thickness of the wall in all three sides (right and left sides, top). You need to measure and diagonal, since this indicator acts as a control in the manufacture of the door frame. The thickness of the box depends on the walls. The second option involves the removal of sizes from the door.

First of all, the sides are measured, and the results are added by 5 cm, and then the threshold, taking into account allowances. It must be remembered that between the closed door and the leaf there should be a gap of 2-3 mm on both sides. The margin between the wall and the frame is ideally 1 cm on each side. This place will be filled with foam. Thus, the door frame is 2 cm narrower than the opening.

Required Tools

You will need tools such as a trowel, hammer, chisel, drill, saw, level, tape measure. The spatula is necessary for applying and leveling plaster when finishing the doorway. The hammer will be needed to fit the elements of the side of the frame and fix the platbands. A chisel is used to remove material when inserting door hinges. Drill is needed for drilling holes: in the wall for the subsequent installation of details of the opening design and in the cloth for fittings. Saw required for cutting parts of the box, trim, dobor. In the case of metal elements, it is replaced by a grinder. The correctness of the position of elements horizontally or vertically is determined by the level. Roulette is used as the main measuring device. In the process, you will also need a plane, a square, a screwdriver, a pencil, a construction knife.

Optional accessories:

  • cutting pliers;
  • construction mixer;
  • grater for plaster;
  • jigsaw.

Box assembly options

They are few. Basically, only three are distinguished: using a tongue and groove joint using the tongue-and-groove principle, with the help of a baguette attachment (at an angle of 45 °) and a combination of elements at a right (90 °) angle. In the middle price range door frames are usually sold unassembled; like semi-finished do-it-yourself products.

The box consists of 3 profiled bars of wood, covered with foil in the color of the door or veneer. Vertical bars usually have a length of 210-220 cm, horizontal - 100-110 cm. Preparedness for installation differs from different manufacturers for products. In some of them the boards are already trimmed to 45 °, taking into account the size of the canvas and are completely ready for assembly. However, most door frames are sold unprepared.

Before proceeding with the assembly, it is necessary to carry out a number of preparatory measures:

  1. All parts are placed on the floor, separately from each other.
  2. The product is inspected for completeness.
  3. Parts of the product and fittings are checked for defects. After installation it will not be possible to return defective items.

Baguette connection

First, take two vertical bars. If the door leaf has a length of 2000 mm and the finish coat is 30 mm high, then the short side of the bar should sum these figures (2030 mm), and with the clearance between the finish coat and the door the final result will be 2040-2045 millimeters. On the inner surface of the bars is set to mark the desired length of the door. Then cut off the excess angle.

On the inside, the angle should be 135 °, which is similar to -45 ° on the outside. Two vertical boards must match in length. The same actions are performed with a short bar for horizontal placement. In this case, you will need to cut from both sides. It is necessary to monitor the correctness of the size. Before you directly do the work, you need to carefully check the measurements.

The clearance between the frame and the door must be 3 mm.

Spike connection

This option implies the presence of grooves in the vertical slats and spikes (ridges) in the horizontal. In the folded form through these alternating elements passes the hole for the screw. With enough experience, this system can be made thorn-groove independently. For this you need a construction bar, MDF-materials will not work. Regardless of whether semi-finished boards are purchased or made by hand, measurements are first made for processing to the required length.

The doorway is measured in several places. As a basis, the result is taken less. You need to know the dimensions of the door itself and add gaps for its progress, 3 mm on both sides is enough, but you can bring the figure to 5 mm. At the top of the vertical strips grooves-grooves are made for connection with the horizontal bar. The length of the latter is calculated taking into account these depressions. From the width of the entire box, subtract the difference in the thickness of the timber and the size of the groove.

Right angle

This is the easiest option to build your own hands. This method involves removing from the vertical posts of the assembled frame the vestibule of the box to the thickness of the vertical bar. The horizontal board is sawn off less, taking into account thickness vertical. All prepared items should be placed on the floor. All parts of the frame are connected with screws. Each side requires 2 pieces. Corner joints of the structure are connected by fasteners, for each of the corners 2 screws are needed.

In the frames, washed down at 90 degrees, they are screwed at the same right angle (at 45 ° - at an angle of 45 °). In order to maintain parallelism of the uprights and match the distance between them, the door should be placed on the frame that is not fully assembled, as it will stand, and fix the gaps with wedges. Narrow holes are also created to prevent the wood from cracking. Cap fasteners should be wound inside the material.

Step-by-step master-class box installation without a threshold

It will take:

  1. Apply tags.
  2. Saw the workpiece.
  3. To mill a place under the hinges.
  4. Assemble the door frame.
  5. Mount it in the opening.

First of all, the markup is drawn on the material for subsequent sawing. This is a very crucial step, because with a slight deviation of the workpiece may be unsuitable for use. To the door served the entire promised time, it is important to make loops correctly. If there is a manual mill, then it is necessary to ideally set the width and depth of the sample, taking into account the parameters of the door hinge.

Before assembling the door frame, it is recommended to drill narrow holes in the places for screws. This technique significantly reduces the likelihood of violation of the integrity of the product. Parts of the box are collected very carefully: even minimal deviations are unacceptable. At the same time, considerable effort is required to ensure a reliable result. Install the door frame without haste. The process uses small elements to pre-fix the frame. The side gaps are filled with foam.

Marking and cutting blanks

The marking of the upper part of the door frame is done like this: a bar is put on top and marks are applied with a gap of 2-3 mm. For the template, you can apply the packaging carton. Its thickness is perfect for this. Markers can be made including a pencil with a sharp end. As for the width of the door leaf, 6 mm is added to it. Door frame boards are cut on the machine according to the marks made. If they are veneered with natural material, then there may be problems with gash.

Natural veneer reaches a thickness of 1 mm, which means that when trimming the board will be stuck with such a slope in the guide. A pointed chisel in places washed down removes a strip of wrapped veneer. This ensures perfect flush and tight junction of box parts. Next, the transverse workpiece and two sidewalls are filed. Dimensions should be checked several times so that the box is not too short, if this happens, you will need to start all over again with new materials.

Hinge milling

Correctly seated hole ensures the correct positioning of the hinge on the door. Accordingly, the door will function properly and will last no less than originally calculated. When drilling a hinge, you need to observe the required depth, maintain the distance from the horizontal and vertical edges, adhere to the perpendicularity of the drill relative to the part, work carefully next to the rounded edges - they can easily get damaged.

Well, if there is a manual router. It is useful in many cases. The tool will need to set the width of the sample, taking into account the corresponding parameter of the loop, as well as the depth, based on its thickness. The machine must be placed on the board of the box for milling the landing nest on the labels. The roundness is removed from the corners with a chisel. During work, extreme caution is important. Do not allow cracking of blanks.

Box assembly

Before attaching the loops, it is better to drill holes with a diameter smaller than the screws in these places. Thus, the probability of cracking the board will be reduced to a minimum. Now you can start assembling the box. Screws must be inserted at right angles to the surface of the cuts. It will be necessary to ensure that the technological grooves do not overlap with the self-tapping screws. Elements must be precisely combined, avoiding a common bias, since it is very difficult to correct such a defect.

To facilitate the connection at the beginning it is better to make narrow holes. When performing assembly, you need to carefully, but at the same time as much as possible to connect the parts. Otherwise, the screw can turn in the first one before it is screwed into the second element - as a result, a gap will appear. Assembly is carried out on a horizontal surface, preferably on the floor.

Installing the box in the doorway

The frame is neatly placed in the opening and for some time attached with pieces of cardboard or foam. Then the construction level checks the correct position of the box from the hinge side. Adjust the gaps and strengthen the structure you need with wedges. They can be made from the remnants of the bars. Wedges are installed under the loops. One by one they are scored in both upper corners.

The verticality of the frame is checked by level. The box is mounted through the holes under the screws. When exposing the sidewalls checked the horizontal upper jumper. If the floor is not perfectly flat, it must be taken into account in advance, and then everything will be installed correctly. During the installation of the box for the stability of the elements need a little zapenit them. Shortly before that, it is necessary to clean the surfaces of dirt and dust and spray them with water, because the adhesion coefficient of the mounting foam to wet surfaces is much higher.

Features installation box with a threshold

Such a frame is required for bathrooms and toilets and to a lesser extent for other rooms. The level of the floor in the bathrooms is often higher than that of the adjacent room, so the installation of a box with a threshold is also necessary to protect against the ingress of water on the parquet, linoleum or other flooring. Fastening parts of the box with the threshold should be made of galvanized screws. The gap for opening the door leaf is made an additional 4 mm more than the option without the lower bracket.

Door frames with a threshold have greater strength, so they can be installed in places where there is a high level of vibration, for example, near railway tracks. Installing a frame with a bottom rail may be required in rooms with a high level of noise pollution. In addition to the soundproofing function, the threshold is able to play the role of a compactor: to prevent air from flowing out and, as a result, to lose heat.

Advantages of door frames with a threshold:

  • partially solve the problem with drafts;
  • protect from dust and smoke.

Useful tips and errors to avoid

Due attention should be paid to the fastening of the door frame from the side of hanging the canvas. You should not increase the number of screws or dowels more than two, because the entire load will be transmitted through loops. No matter how many screws fasten between them, they will not change anything. There will be only extra holes in the box, sometimes very noticeable. Hardware fasteners can be hidden. It is only necessary that they are securely installed. Even the slightest hesitations must be eliminated immediately.

The fact is that the foam holds the lateral load well, but it is practically useless in compression. Not a problem if some fasteners were longer than necessary, and came out slightly on the other side. This will not affect the fixing strength. If there are no cracks on the frame, then everything is in order; it will only remain to mask the defect a little if it catches the eye. However, it may not be visible at all.

If the box is made of natural wood, then the screws are used with a large pitch, and if it is made of micro-wood fiber, it is used with a small pitch.

Conclusion

To assemble the door frame, you must be able to use the tools and make measurements. In this case, accuracy is important. The material should be selected durable, for example, oak, despite the fact that it is denser and, therefore, heavier than many other species. One of the key stages of work - the removal of the size.

It is very important to make the gaps correctly. If the planks are not initially ready for assembly, you will need to process them, giving the desired size and shape. The second most important point after the measurement - milling under the loop. The ability of the frame to withstand the load created by the sash for a long period of time depends on this simple-looking process.

After creating all the necessary holes, assembly begins. At this stage it is not recommended to rush. Installing the box in the doorway completes the cycle of work. Throughout this period, you will need to regularly measure the correctness of the position of the product and its parts.
