Safely widen the doorway with your own hands. Widening a doorway with your own hands Widening a doorway with your own hands

Increasing laser cutting passage

Not always standard layout apartments satisfy the wishes of their owners. In this case, there is a need for its redevelopment, and often the doorway needs to be expanded.

Such work is carried out after accurate calculations and the availability of special tools. The article will tell you how to do this.

Augmentation process

Any redevelopment of the apartment requires compliance building codes. When moving or expanding the door opening, in load-bearing wall weakening of the house structure and the occurrence of deformations should not be allowed. Because of this, the redevelopment project must be approved by the state supervision authorities.

Some ways to widen a doorway are presented in the table:

Expansion method	Peculiarities
Rough enlargement	To carry out DIY work you can use: Hammer. Sledgehammer. Jackhammer. In this case, the contours are preliminarily outlined, and then the excess material is knocked down with tools. The process is quite labor-intensive, and the formation of microcracks that appear due to strong impact loads can lead to a decrease in the strength of the wall structure.
	In this case, a grinder is used, with which you can quite easily enlarge the door opening along the intended contour. The disadvantage of the process is that you need to cut the wall on both sides. Dry cutting produces a lot of dust and rapid wear of the diamond blade.
	This method is accompanied by the use of a spray bottle, which irrigates the surface while working with the grinder. It is more rational to use a special construction cutter equipped with diamond blade large diameter and water capacity. In this case, in one approach you can cut off excess sections of the doorway in the wall the right size with minimal contamination. But the price of such equipment is quite high.

Standards and approvals

Regardless of the purpose of the building, it has an opening for a door to enter the building and for communication with neighboring rooms.

There are several reasons why you need to increase the size:

Many people want to visually expand the space, make it light and spacious, without changing the dimensions of the living space, as in the photo.

Increase

The opening cannot accommodate the purchased modern fashionable door design.
Making doors to order.

Advice: Before enlarging the opening in panel house, it should be borne in mind that this is painstaking and not entirely simple work With existing risks, in compliance with standards and tolerance norms.

There are no particular problems in enlarging the door opening in any wall.

But in a load-bearing wall they are quite large:

In the absence of a building plan, it is impossible to determine the purpose of the wall, whether it will be load-bearing, which will require additional reinforcement of the structure, or whether it is enough to just reinforce the ceiling with beams.
It is necessary to have agreement with the BTI. This will confirm the fact that the load on the wall with an increase in the width of the door will not exceed the impact norm.
You must obtain the appropriate permit to carry out work.

When remodeling an apartment, it is necessary to take into account the parameters of the standards specified in SNiP.

The following dimensions are provided for door blocks:

The width of the structure is from 55 to 80, which depends on the purpose of the opening.
Doors for plumbing units, transitions to the kitchen - 55 centimeters.
For living rooms, bedrooms and entrances - at least 80 centimeters.
Height can vary from 190 to 210 centimeters.
Thickness - 75 millimeters.
Manufacturers offer ready-made blocks, the width of the frames ranges from 15 to 70 mm.

Advice: When determining the dimensions, you should adhere to the requirements of SNiP and familiarize yourself with the existing restrictions on its expansion.

How much you can expand is suggested by the instructions, which combine the following rules:

The maximum permissible dimensions of the partition for a load-bearing wall can be: width - 2 meters, height - 2.1 meters.
As the size increases, the spans between neighboring rooms it is necessary to additionally strengthen the ends with supports.
Extended to maximum sizes and more passages in the main walls, it is recommended to strengthen them with supports in the center.

Strengthening

Important documents when expanding the passage between rooms in an apartment are:

Plan of work stages.
Architectural plan.
Floor plan of the building.
Extract from the house register, if available.
Certificates from the BTI regarding permission to carry out redevelopment.

Preparation for work

Having decided on which wall the doorway will be expanded, you need to find out about it:

Is there hidden wiring inside the wall?
Presence of fittings or pipes.
Is there a chimney and where is it located?

To obtain this information, you must use a metal detector. If any obstacles are found in the wall, they can be removed:

Move the electrical wiring to another location.
Retreat at least 300 millimeters from the chimney.
By dismantling pipes and moving them to another place - but this will require the help of a specialist.

Extension order

Interior enlarged passage

Increase doorway in walls made of any material, includes performing sequential actions:

Marking the required dimensions of the structure.

Marking

Dismantling the desired area.

Strengthening the opening to ensure its strength and prevent collapse or deformation.

To dismantle the structure, you can use percussion instruments sawing or hole drilling equipment.

Depending on the material from which the wall is built, these may be:

Hammer.
Jackhammer.
Special a circular saw with a diamond wheel.
Bulgarian.
Electric drill with diamond drill.
Hand tools: chisel, hammer, sledgehammer.

Advice: More attention should be paid to working with high-strength concrete walls. It requires a lot precise work, and excluding vibrations and damage to surrounding structures.

For work you will need the following materials:

Wooden beam.
A corner with dimensions of at least 35x35x4 mm.
Components for making concrete mortar.
Boards.
Hardware.

To better imagine the process of increasing the door opening, you should watch the video in this article.

Expanding the passage in a brick wall

The work is performed in the following sequence:

Mark along the contour.

If necessary, the jumper is moved.
The upper masonry is reinforced with a metal channel.
Using a grinder, a part of the wall is cut out according to the marks.

To clear the perimeter, use a chisel with hammer blows, a drill or a hammer drill.
It is better to remove excess elements from the wall by hand, after first removing the mortar from the seams (see).
A welded structure is installed around the perimeter.

Advice: After completing the work, you should check the integrity of the brick wall. If splits or cracks are found in the seams, they need to be plastered.

Expanding an opening in a concrete wall

Expansion in concrete wall: installation order

To carry out the process correctly, you must first:

Prepare the space for work: cover furniture and other objects with construction film, which will protect them from excess dust.
Buy special bags for collecting pieces of wall and other debris, which are then quickly and easily taken out and loaded into the car.
Use a respirator and special glasses to protect your face and eyes from dust and small fragments during dismantling.

Stages of increasing sizes:

The old door structure is dismantled:

A nail puller tears off the trim and trim.
The canvas is removed from the hinges by prying it from below with a crowbar.
The vertical posts are cut with a grinder and torn off with the same nail puller.
The top jumper is torn off or left in place.

A contour for increasing the span is marked along the perimeter of the wall.
Holes are made along the contour with an impact drill to simplify further destruction.
The panel is cut one at a time on each side.
After cutting through the reinforcement, the remains of the wall are removed with blows with a sledgehammer.
The opening is strengthened metal corners, slats or pieces of rod.

Order of increase

No matter how the expansion is carried out, it is necessary that the entire process is carried out in accordance with safety requirements.

There are times when during installation new door the doorway needs to be widened. For example, when remodeling an old home, when the owners want to radically change the interior of the apartment. In addition, the purchase of large-sized furniture requires expansion, since there is no other way to bring it into the apartment. This problem usually occurs among owners of old small apartments built in Soviet times.
An example of expanding a doorway to a balcony

According to GOST, there are certain standards for door parameters, but in reality, doorways can deviate more or less. IN given time in most cases, manufacturers adhere to generally accepted standards and produce canvases in accordance with GOST. But, if the opening does not fit in size, then you need to overpay considerably when ordering a custom door. It is worth noting that in standard documents standard sizes are prescribed depending on the purpose of the rooms in the apartment. Let's consider the dimensions according to GOST for a one-room apartment:

If the apartment has many rooms and there is a living room, then with an opening height of 2000 mm, the width can vary from 800 to 1200 mm.

An example of expanding and strengthening a doorway to the living room

If the doorways in your apartment meet the standards, then you will not have problems choosing a new door leaf, since the range of these sizes in stores is large.

If there are significant deviations in any direction, then you need to order an individual model. It will not be cheap, and if you add the installation price to the cost of the door, you will end up with a rather expensive pleasure.

It will be much cheaper to carry out such a process as expanding the doorway under an ordinary door. This option is inexpensive and widely available. What to overpay for individual order and for additions or a thicker frame, it is better to slightly adjust the door opening itself and.

Extending the doorway of a panel house

It is important to know that before carrying out work to expand the doorway of the front door, you need to obtain permission from the relevant authority, since this is a redevelopment that needs to be legalized.

Stages of expanding a doorway in a panel house Before starting work, you need to carry out preparations and cover the furniture with polyethylene. In addition, it is worth stocking up on safety glasses and gloves to prevent injuries during work. To increase the opening in the apartment panel house you need to do the following:

Expanding the opening for doors in a brick or concrete wall

Extension in a concrete house

Before starting work, you need to prepare a drill and more than one, a chisel, a hammer drill and a sledgehammer. This will be a drilling expansion method. There is another way to enlarge the opening using a grinder, but you should understand that this is a very dusty job. Drilling method – technology:

Interesting: in the case of expanding the entrance in a concrete wall, it is not necessary to reinforce it.

Expanding the opening in a brick building

We looked at how to expand the opening in a panel house or a concrete wall, but questions may arise about the increase in a brick building.
An example of expanding and strengthening an opening in brick building In case of brick wall Some difficulties may arise, since if the force is applied incorrectly, the entire brick structure may collapse, especially if it is made poorly. Step-by-step instruction:

dismantle the door and outline the expansion contours;
in this case, it is necessary to strengthen the opening using a profile corner and jumpers;
You only need to do the work with a grinder, since using a sledgehammer or a hammer drill, you can knock out excess bricks;
as soon as the opening is enlarged, inspect the brickwork of the wall; it should remain intact. If there are cracks, they are sealed with cement mortar and after.

Ways to strengthen the opening after expansion in the main structure

When the doorway is located in a load-bearing wall and needs to be made larger, you need to understand that the load on this structure will be increased, so you need to strengthen the opening first. You can use special profile structures or ordinary fittings, it all depends on financial capabilities.
Algorithm for strengthening an enlarged opening for doors in a supporting structure:

Take a steel beam and mount it on the opening, in its upper part, under which a small niche is cut out.
Fill the voids with cement mortar.
Then install the channel.
Then the vertical part of the opening is strengthened.

You can simply weld a special frame to the size of the opening and install it as reinforcement.
Option for strengthening the opening with a special frame Expansion doorways- a job that cannot be completed without dust and dirt, so before starting you need to cover all furniture and household items well. In addition, you should take care of your own safety - wear gloves, a protective mask and goggles. Important! Before you start enlarging the doorway, weigh and measure everything well. Do not also forget that between the door frame and the wall there must be at least 3-5 cm of free space, which is filled polyurethane foam during installation.

To enlarge doorways you will need plaster, primer, nails, screws, a metal frame and guides, as well as a spatula and squares. The transfer process consists of two stages: moving the opening a few centimeters and expanding the opening in width and height.

Increasing the height of the opening in a panel house is carried out by cutting monolithic design to the required height. If the doorway is in interior partition, then in this case the opening is enlarged using corners. Reducing doorways is done using a special plasterboard structure.

Refinement in height up to 6 cm is carried out by plastering the doorway, and above 6 cm, a structure made of plasterboard or brick is required. Brickwork is durable, while plasterboard is lightweight. Sometimes it is necessary to move a doorway. The opening from a monolithic wall can be cut off. And if the doorway is in brick wall, then you will need to transfer all the elements. Both processes involve either building up the wall or cutting it off.

Stages of work to increase openings

Increasing the height of openings includes a number of preparatory work. First, using a level, marks are made on both sides of the opening. Next, the old opening is dismantled. Then holes are made along the marked line. Carefully remove concrete or brick using a sledgehammer and hammer. This method is traditional, but best result is achieved using special equipment equipped with diamond cutting discs. Following the specified marks, the plaster is removed along the entire length of the beam. The next stage is laying bricks along the side of the wall to the marks.

In brick and monolithic walls You can change the size of doorways by no more than 21 cm in height and 20 cm in width. The expansion of doorways may be accompanied by the appearance of cracks or chips. Therefore, upon completion of the work, you should carefully inspect the wall and eliminate all defects. A cement layer is placed between the top of the opening and the brickwork.

Often there is a need to strengthen and strengthen openings. If this is a concrete wall, then you can strengthen the opening with the help of channels. Brick construction reinforced with metal or concrete lintel. If the doorway is located in a load-bearing wall, then the work is carried out subject to permission and a project that describes the stages of the activities, the procedure for increasing the opening and procedures for strengthening the structure.

To understand how to make a doorway in a brick wall or simply expand it, you need to understand the structure of the masonry and the principles of installing a lintel over door frame. You should also not forget that in front of you there may be an ordinary partition, but there may also be a load-bearing wall, and here the process becomes more complicated.

This is exactly what we will talk about, and in addition to the material, we will watch the video in this article.

Door and window openings

In the partition

Basically, with technical point From our point of view, there is not much difference in such actions as expanding or creating a new seat, since moving a doorway in a brick wall means, first of all, inserting and securing a lintel at the top.
This function is the most important for both partitions and load-bearing walls, and dismantling is much easier. But, first of all, you need to outline the location of the opening or its expansion.

As a rule, in such holes on the partitions a thick timber, and if you need to expand it, then all the same, just like when creating a new opening, you need a new lintel.
Therefore, first of all, mark the place for such a beam and cut it out with a grinder ( building brick cuts diamond-coated blades well). Then insert the crossbar there and fix it tightly so that its ends have absolutely no play.
The ends of the lintel must extend beyond the edges of the opening by at least 10 cm in each direction. Can be used as a beam wooden beam or metallic profile, and the rigidity of the fixation of the ends of the crossbar will be responsible for the reliability of fastening.
Fill possible gaps with stones, broken bricks and throw in cement-sand mortar to create a monolith - this instruction is the same for partitions and load-bearing walls.

To make the opening neat, the vertical lines also need to be cut with a grinder, as shown in the photo above.
Of course, a disk with a diameter of 250 mm is best suited for this, but such a powerful angular Grinder Not every home has one - the most common is a grinder with a 180 mm disc, but you can use this one.
Standard or double sand-lime brick M 150 has a bed width of 120 mm, therefore, if the partition is made of half a stone, then even a large disk will not cut through it.
But if the masonry is made solid single brick in a quarter stone, then a disk of 230 or 250 mm will pass through it, and a disk of 180 mm will pass a little more than half. For dismantling, this option is not a problem - the brick will still break and the contour will be relatively smooth.

When the crossbar is inserted and firmly fixed, you can begin dismantling the masonry and you need to start with one brick, clearing the seams around it as much as possible. Then you simply break this brick with your own hands using a hammer and chisel or hammer drill.
You can also, to facilitate dismantling, drill 5-10 holes through the brick (this is easy to do with a hammer drill) and after that the stone will split much better.

Advice. Diamond-coated discs generate a lot of dust, which settles for a long time afterwards.
To reduce its amount, generously wet the cutting area with water, and place the grinder on vertical lines so that it throws dust onto the floor and not into the ceiling.

In a load-bearing wall

If you don’t know what kind of masonry is on the load-bearing wall and the opening needs to be made initially (not widened), then go through the wall with a crown cutter for concrete and the diameter, while trying to take the crown as large as possible so that your hand can fit through it, or you can even illuminate it with a flashlight .
This way you can find out the number of bricks that you have to go through, after all, then the insulation, and then another half brick. You understand that the visible front of work is much easier than the incomprehensible, that is, invisible.

The beginning of dismantling is the same as on the partition - you draw out the opening, cut out a place for the crossbar and firmly fix it. Then you select an opening on one side of the wall and make metal supports for the crossbar, as can be seen in the photo above.
At the same time, do not forget that the price of negligence or disregard for safety rules in in this case– human health or even life – an unsupported ceiling may fall.
Dismantled brickwork doorway on both sides of the wall so that the supports are on both sides and the structure does not weaken. After the opening is ready, the metal supports are connected to each other with metal strips for rigidity.

Advice. In order for the opening to coincide on both sides of the load-bearing wall, you need to drill through it at the cut points (in the corners and several holes along the lines).
The hammer drill must be strictly perpendicular to the wall.

Well, if you are interested in how to properly brick a doorway, then on both sides, after 2-5 rows, drill pieces of reinforcement into the end of the wall to create a bandage. After such an operation, the masonry will be complete and after plastering or puttying no one will know that there was an opening there before. (see also )

Conclusion

Now you know how to block a doorway with a brick or vice versa, how to cut it out in such a wall. Don’t doubt your abilities and feel free to get to work – if you follow the recommendations, you will succeed. But for multi-storey building You will need approval from the relevant organizations for dismantling.

Widening a doorway is a very responsible and time-consuming task. To cope with such a task, you will have to make a lot of effort, and we're talking about not just about physical actions. After all, before starting such work, it is necessary to obtain the appropriate permission. In this article we will look in detail at all the intricacies of the process of increasing the doorway, and also provide several specific examples successful implementation of the redevelopment.

Peculiarities

Many people are interested in whether working with an opening is considered redevelopment. The answer to this question is clear: redevelopment is considered to be absolutely any structural change in the premises, which is listed in the corresponding BTI plan.

If you want to redo a doorway in a private house, you won’t have much trouble. However, when it comes to expanding the opening in multi-storey building, then things take a completely different turn. To implement such a decision, a special project documentation. And all subsequent work must be carried out strictly in accordance with the papers. After all, the slightest miscalculations can lead to disastrous results. For example, mistakes when independently interfering with the structure of a house can provoke the destruction of a building or a load-bearing wall. In addition, in this case, you will receive a monetary penalty from government authorities.

And eliminate Negative consequences work will have to be done at your own expense.

When you need to redo a doorway in a panel house, you can easily find out the specific dimensions and possible options design changes. Since such houses were built according to the same type, the requirements for them are the same, while increasing the height or width of the opening in a brick building is possible only after preliminary calculations.

In general, the size of most interior and entrance doors does not exceed 70 or 80 centimeters. The maximum permissible dimensions of the structure are no more than 200 in width and 210 centimeters in height.

Violating such parameters is only possible with additional strengthening.

How to expand?

There are several ways to perform this task, and to complete each of them you will need different instruments. Let's take a closer look at the three main methods.

Using a hammer drill and jackhammer

This is the most obvious, the so-called “rough” method. To work, you will need a hammer drill, sledgehammer or other similar tool. Next, you need to mark the areas around the perimeter of the doorway that need to be removed. Now all that remains is to knock down the excess concrete with a hammer drill or jackhammer. To implement this method, no special preparation or long time is required.

However, we should not forget about the significant disadvantages of this technique. Firstly, such a process is very difficult and energy-consuming. Secondly, due to excessive load or improper handling, cracks may appear in the concrete wall. This means that additional Finishing work to hide the flaws that appear. Moreover, gaps that are too large can cause significant damage to a load-bearing wall.

It is very important to remember this when performing work and strictly monitor the process.

Using a grinder

If you want to quickly and easily make cuts in reinforced concrete walls, then you can use the all-known tool - an angle grinder. It can even cut through rebar with ease. Just be extremely careful when making a cut, since it is important to make it equally on both sides of the wall. Minus this method is the formation of a large amount of dust and rapid wear of the grinder’s diamond blade. And also the fact that an even cut requires special skill.

But you can use a little trick to make the process cleaner. To do this you will need a regular water spray bottle. Simply spray the wall surface regularly to prevent the spread of dust and dirt.

This way, the process of increasing the opening will become much more convenient and safe.

Using a construction cutter

This option changing the size of the doorway is most acceptable. A special construction cutter is a tool that consists of a diamond cutting disk, as well as a container for storing water. Using such a device will allow you to quickly, accurately and without dust expand the opening in width and height in wooden house or brick building.

Upon completion of the process of enlarging the opening, it is important to carefully inspect the walls. If any chips or cracks are detected, they should be repaired immediately to avoid further destruction of the material.

How to increase?

So, now you know exactly how to increase the size of a doorway. But what to do if you need to reduce them? This situation may arise if you cut off the excess when expanding the space. Or you simply needed an extension to install a smaller door.

The specific method required to implement such work depends entirely on the material from which the wall is made. When building up a brick opening, brick is used, cement mortar, spatula and others auxiliary tools. Take accurate measurements and start laying. Please note that to increase the height of the opening, it is important to make a lintel from wooden block and fittings.

If you neglect this rule, the structure may simply collapse.

When you need to reduce the opening for interior door, you will need regular drywall. After taking all measurements, apply a special adhesive composition on the side and top of the opening. Then glue the pre-cut drywall pieces. This method is the most optimal when remodeling an apartment. It won't require a lot of time or money. To build up an opening in a wooden house, you should use timber.

And to change the size of the opening in a concrete wall, it is optimal to use cement mortar.

How to agree?

As we said above, it is important to coordinate work on changing the size of the door opening with BTI.

First of all, you need to prepare a package of all necessary documents, which include:

relevant statement;
redevelopment plan;
BTI technical passport.

You will also need a special permit from the SRO, which will state the safety and possibility of redevelopment.

So, now you know everything about the process of widening and reducing the door opening. The information from our article will help you quickly and easily cope with this task. The main thing is to do correct calculations and strictly monitor the safety of the procedure.

We also remind you once again that carrying out any redevelopment without the appropriate permission is strictly prohibited.

Successful examples

Let's look at a few specific examples of correctly changing the size of a doorway.

Expansion of an opening in a load-bearing wall with reinforcement

Presented here clear example competently enlarge the opening in compliance with all necessary rules. Concrete cutting was carried out according to a pre-marked pattern, after which the structure was strengthened using metal frame. This prevents the appearance of cracks and faults in the future. This is very important when it comes to a load-bearing wall, because its deformation can lead to the destruction of the building.

Enlarging the opening in the form of an arch

This work requires great experience and dexterity. Accuracy and precision in carrying out such a process is achieved with the help of the professionalism of the craftsmen and the efficiency of special equipment. Specifically, diamond cutting technology was used to enlarge this opening. It's modern and effective way to change the size of the doorway. The resulting structure is securely fastened with strong metal plates, which are fixed to special anchor bolts. It should be noted that to implement similar project You should only contact experienced specialists.
