Attaching an extension to a log house. An extension of the veranda to the wooden house do it yourself

03.06.2018

Hello dear members of the forum!
Last summer, he decided to make a one-story extension 7.8x3.6 m. With a kitchen, bathroom and toilet to the existing cut 6x9 m. The log house was already settled, it stands on a finely blurred (40 cm) foundation, under the foundation of sand 30 cm.
In the fall, the ribbon foundation was filled under an extension of the P-shaped form, the foundations did not connect the foundation width 40 cm and buried inside the basement the shallow well, 2 m. The foundation of the log house has a release of approximately 15 cm in the direction of the new foundation. The new foundation turned out 3 cm below the log foundation. After the winter, even the cracks did not appear on the site of the "gluing" of the 2nd foundations.
Plot in Naro-Fominsk. Grown clay, the corve walks from 1 m to 1.7 m depending on the season. I understand that it was possible to make mistakes, but what is there, that is. The function of the house at the moment is a cottage, often come in winter t. K washed. Now I break my head over what to build an extension.
Walls: Initially wanted to make frame (from the inside out) OSB + vaporizoation + stone wool + windproof + vent. Clearance + Blockhaus, but after reading from what insulation and wall panels I decided to refuse. I have two young children and the risks of their health should not be (someone did not say, but the stone wool is dusting and distinguishes the firm glue, OSB and plywood is also not safe adhesive). The dry bar is unfortunately worth the big money and find the "right" supplier is difficult. The profiled did not consider due to the complexity of the cacopa, glued because of cosmic high costs.
While he stopped on the walls of foam concrete blocks (Text Mason), with further warming of stone cotton or from a natural humidity bar (150 or 200, planed from the inside). I'm more inclined to block construction, the thickness of the wall 200 + insulation. The final cake of the walls should turn out (from the inside to the outside) Blockchaus + Bar 2.5 cm + Foam concrete unit 20 cm + Rockwill Light Batts 10 cm + windproof + Bar 2.5 cm + Blockchaus. But there is an opinion that foam concrete can not be frozen-defrost, but it will be constantly, since I go to the cottage only on weekends. The natural humidity bar scares the shrinkage and as a result of the possible problems of connecting 2 roofs, pantry and trim.
Paul: Film (polyethylene) and powder sand, lags 200х50 for the foundation, between Lagas Ursa Pure One (seemed the most secure from budgetary insulation), in the lags, sex board. Foundation Floor Pie should Operate (from the inside) Floor board + vaporizoation + Ursa Pure One 20 cm + Obsek
Ceiling: on the principle of gender. The final cake of the ceiling must turn out (from the inside out) lining + vapor barrier + Ursa Pure One 20 cm + windproof + Next ventilated chardak.
Does such an extension have the right to life? I will accept any criticism, since the builder is not

K. wooden house - This is an additional room that can perform functions. summer cuisine, terraces, residential room. But with any embodiment, its construction obeys general technological principles.

An extension to a wooden building can be made with their own hands, but initially it is worth familiar with the nuances of its construction, choose the material, decide on the type and floor.

Foundation

The technology of arrangement of the foundation for an extension is practically not distinguishable from the fill of the main base. Formwork is also mounted, the frame is installed, the concrete mixture is poured. The main thing is to pay attention to, is the correct connection of the attached part to the already existing one. As a result, the design should be obtained as close as possible to the monolithic.

Works are manufactured according to the following scheme:

· First, you need to release the foundation site, bordering the additional part. The base should be purified from all elements (including waterproofing) to the full depth of the new foundation.

· Install on the punch of the nozzle on concrete (size 10-12 cm) and chop multiple deepends 6-8 cm long.

· Replace the nozzles on the drill and make recesses for reinforcement.

· Secure the reinforcement rods in the old foundation, tie them a new base frame and set to form a formwork.

· Rinse the old foundation, pour a concrete mix into a formwork and give the base to dry well.

Features of docking walls

The extension to the wooden house can be made of any suitable material (concrete blocks, wood, brick). The main issue to pay attention is the correct connection of the old log cabin and an extension.

The very trouble-free material for docking is a tree, and the easiest way this stage will be passed when using the framework of the extension. To connect new walls with already standing log cabins, large self-tapping screws are used, and the joint is sealed with polyurethane.

If an extension is made of bricks or blocks, then an intermediate mortgage element will be needed for high-quality docking. Most often for this purpose, fittings, metal corner or channel are used.

1. Armature.

Iron rods are clogged into wooden walls in such a way that there is no one for the outside. When fixing the reinforcement in the new wall, it is necessary to monitor the iron to lay between rows of blocks. The rods are grabbing with cement mortar and will provide high-quality docking of wooden and block cloths.

If a cast design is attached to a wooden building, the reinforcement can be fixed chaotic. The rods are installed every 5 rows, 2 elements per row.

To ensure a sealer compound of two surfaces, it is necessary to leave a small gap (1-2 cm) between them, sew it and close it with cement or asset.

2. Schweller.

A stronger type of wood and block cloths. The size of the metal part must correspond to the parameters of the material used in operation - that is, blocks must be freely placed in the chambers.

Large self-tapping screws are suitable for attaching an element to the tree. For tightness of the compound, you can take suitable seals or polyurethane sealant.

3. Metal corner

By and large, it is a cheaper type of channel. For its manufacture, you will need a corner (100x100 mm) and iron strip (50x5 mm). With the help of electric welding items give P-shaped And fixes on the surface as well as a channel.

Extend the life of the metal will help high-quality processing of parts by anti-corrosion compositions.

Overlapping an extension

For mounting the ceiling overlap, bars are used, which are fixed along the upper surface of the walls and secure special corners.

If the extension is made of brick, then the ends of the beams can be wrapped in rubberoid and impere into the concrete fabric.

Roof

The roof of the extension can be performed in different versions, but most often choose a single design type. Before starting work, you need to decide with the angle of the skate. The minimum inclination of the tilt is 25-30 degrees.

· Next, you need to draw a horizontal line on the wall or facade of the roof. For this feature, a bar will be recorded that supports the upper part of the rafter. Below, they will rely on the boundaries of the wall or beam overlap. The release of a bar for the contour of the walls by 25-30 cm is allowed. This will help protect the surface from atmospheric precipitation.

· Secure rafters with metal corners.

· If the extension is placed on the side of the main roof, then problems can be fixed with the transverse beam. The removal of several lower sheets of roofing material from the main log cabin will help to leave the position. Released beams can be used to fix rafters and combining two parts of the roof.

· Laying of roofing material on the extension should begin from the bottom up. For the correct docking of the old and new roof, it is necessary to slip the upper row of the roof of the extension under the lower row of the roof of the main building.

· If the upper part of the new roof is joined with the front surface of the roof or the wall, the connection site must necessarily be hydroizing.

Having finished working on the construction of the roof, you can proceed to the insulation of the walls and the floor of the extension.

Output

An independent manufacture of an extension to a wooden house is not much different from the construction of a separate building. Before starting work, it is necessary to explore the general rules for construction, remember the nuances of the union of the old cut with a new building, and in the construction process - to accurately follow the technological principles of such events.

Useful advice and articles

When there is little place in the house, the tenants think that it would be good to make an extension. For people who understand little in construction, the construction of an extra room can cause many questions. In this article we will try to figure out which types of attacks are, from which material it is better to make them, what stages for the construction of the construction must be necessary.

Types of attached to a wooden house

Depending on the type of building, the material, insulation, base and windows of the future room are selected. It can be a kitchen, toilet, garage. In the middle strip of Russia, you can often find a greenhouse that is attached directly to the building and has an entrance from the house - it is very convenient.

Watering can be done from the central water supply. It is clear that the construction of any construction must be coordinated with the supervisory authorities and fulfilled with the technical regulations.

The construction of any design to the building involves several stages:

Of course, the construction of the room is better to produce from the same material as the house itself, but it is not always possible. If the house is wooden, and the new room is planned to be made more massive, then it is best to build from foam blocks.

An extension is better to do from the same material from which the house itself is.

Features of the construction of adhesives from foam blocks

Start the construction of an extra room from foam blocks, it is necessary to draw up a plan:

Recently, cellular concrete has been greatly distributed as a material for construction. No wonder. Mesh concrete is light, with him you can make an extension to a wooden house without much effort.

Many builders choose this particular material, because the foam blocks can be saved on the basis of: instead of a ribbon foundation, use the base on the pillars, for example.

The use of high-quality blocks is a guarantee of reliability of construction. Attention should be paid to the color: it should be uniform. Cellic concrete should not have chips, cracks, stains.

Foundation device scheme for an extension of foam blocks

Order material follows in a large enterprise, which has its own production. It is best to order blocks from one batch. Construction should be started only using well-dried blocks, in dry weather. The block structure will be successfully erected both on the tape and on the base.

Foundation columnal

The advantage of this type of construction is not only its low cost, but also the fact that the owners will always be able to access Earth under construction. The construction of a columnar foundation is recommended in the area where there is a lot of water in the soil.

Ribbon foundation

More thorough construction should be treated with a belt foundation. This base for the construction is more expensive, but it will have to be repaired not so often. In addition, builders recommend making a ribbon foundation for an extension if the main building has the same type of foundation: it will keep the construction from the skew.

Monolithic foundation

Such a foundation for an extension will suit both the wooden house and the construction of foam blocks. This foundation will be very durable, there will be a century. However, its cost is so height, that it is impractical as the foundation of an extension.

The monolithic foundation for attachments is almost never applied.

The main stages of the construction of foam block exercises

Works consist of the following steps:

With the help of an extension from foam blocks you can significantly increase the living area of \u200b\u200bthe house

The seam thickness between the foam blocks should not exceed 3 millimeters!

Features of the attachment of an extension to a wooden house

Before starting the construction of an extension to a wooden house, you should carefully examine the walls of the main building. If there are rotten brices, they should be replaced. It is not bad to treat the wall with substances from the occurrence of mold, to cry with paint or varnish. At this stage, it is necessary to think about whether the insulation of this wall between the house and an extension will be.

Scheme of the technology of the standard basement device under the extension of foam blocks

Then it is necessary to split the foundation that belongs to a wooden house and a new one. To do this, the armature is inserted into the old foundation about a meter.

The second part of the reinforcement is sewn into the foundation for an extension to the house. If the foundation is columnar, the extreme pole joins the wooden house in the same way.

Additional room extension scheme to residential house

The distance between buildings is best laying out the mineral wool, then you can make wooden planks and decide the design of siding. Such an approach will allow not only to save the house from the skew, but also will retain all the heat inside the room.

The roof of the construction of a cellular concrete should be lower than the roof of the main building. This approach will avoid problems after shrinkage, besides, atmospheric precipitates will not fall on the part of the main building.

Now you can go to insulation. You can use almost any available material. Just do not forget that foam blocks require a mandatory installation of vaporizolation.

Scheme of fine-breed foundation for an extension of foam blocks

Let's summarize:

To the wooden building, the construction of foam blocks can be attached;
The foundation of the construction can be a column and tape, monolithic is not recommended;
It is necessary to wait for a shrinkage of a belt foundation;
The walls are installed from foam blocks, additional strengthening elements can be used (solution, fittings);
Passages Install using wooden backups and jumpers with hollow;
The roof is not a hardware design, from wooden beams;
Walls to the main building we attach without hard fastening;
The roof of the extension should be lower than the coating of the house.

Video

You can watch the video on how to correct the extension of foam blocks.

An extension to a wooden house is a good option for the formation of an additional residential or functional room in a country structure. It can perform a huge number of functions, depending on the wishes of the owners: garage, boiler room, living room, kitchen, terrace, veranda, etc.

It is possible to make such an extension correctly and do it yourself.

The design can be made of a variety of materials: a bar, based on a wooden frame, made of foam concrete blocks, bricks. In addition, there are many projects for attachments. In the absence of skills in the development of projects, it is natural to turn to a specialized firm.

Extension of frame type

Frame extensions B. last years The steel are especially common, because they have a lot of advantages over their analogues:

Relatively fast construction work;
Everything can be done with your own hands: ranging from project development and ending with internal arrangement and insulation;
Minor financial costs for building materials and labor costs;
In compliance with all technologies, you can get warm, comfortable for accommodation, durable, reliable and durable structures made on the basis of a wooden frame;
Framework technologies Experts strongly recommend choosing if the extension is assumed to have two floors.

Frame extension.

Of course, before starting construction work, regardless of the functional purpose of the annex (garage, kitchen, living room, etc.), it is necessary to carry out all the necessary calculations, the study of the soil and make the project. Designing can be performed independently or with the involvement of specialists. It will be right to contact a specialized company or to private craftsmen who for a certain amount will be able to make a project, which is guaranteed to be taken in controlling bodies when considering documents for an extension.

It is worth noting that the extension frame can be made of both wood and metal base.

Wooden frame will be cheaper and easier, will not give extra load on the foundation, but the metal basis is more durable and more reliable. Wooden frame production is conducted from bars and boards. The foundation for the frame extension will correctly make tape or monolithic using cement mortar. There is no difference, how many floors will have a design, or what materials for construction are used. The use of pile, columnar or screw bases will be relevant with heavy structural elements. Almost any kind of foundation can be made with your own hands.

Foam concrete unit

Foam concrete blocks are also actively actively used today country construction. They are used to make their own garage, household structures, verandas, arbors, extensions.

Among the main advantages of using foam concrete blocks to build an extension to country house You can allocate:

Laying blocks will not require any special skills and experience;
An extension to a wooden house from blocks is not inferior in terms of environmental and safety in natural wood;
Fake-up-resistant foam concrete blocks, resistant to moisture, do not let the cold air and do not produce warm out of the room;
Upon completion of the construction, there is no need to wait for some time to shrink the material (in contrast to the log);
Relatively low price blocks;
High strength characteristics, simplicity in handling with infirred materials;
Blocks can be used in the construction of buildings on complex soils;
Foam blocks have a small weight, therefore there is no sharp necessity in a powerful and expensive foundation.

From foam blocks you can make an extension of any type: living room, kitchen, garage, veranda, terrace, economic structure, etc.

Moreover, foam concrete blocks In the process of construction, you can easily bind your own hands to the cut, because the porous material, like the log, is well processing.

From foam concrete blocks, you can build an extension of any sizes and shapes. The main thing here is to draw up a project in advance and provide for the use of effective waterproofing and thermal insulation materials. Experts note that when erecting an extension from foam blocks it will be much easier to legalize, unlike wooden or brick structures.

An extension of bricks

An extension of bricks to a wooden house is probably the most difficult version of all available for sale with your own hands. However, many country households still choose it, despite the more rational solutions in all respects.

It should be immediately noted that it will be not easy to tighten to the brick extension to the cut and other wooden parts - for this you will have to use special connection technologies and fixing elements. In addition, in places in contact with bricks and logs, it will be necessary to lay a layer of heat-insulating and waterproofing material.

For an extension of a brick, which will have a significant weight, it will be necessary to make a fairly powerful foundation.

The optimal solution will be the monolithic or tape concrete base. Need to remember that country house You also need to tie. This is usually done with the help of fittings, which is inserted pre-in the thickness of the old foundation. In cases where complex soil conditions are observed on the ground (for example, bubbly types of soil), fix the walls and foundation of the brick extension and country wooden house Not worth it, because such an approach can lead to partial destruction of two structures.

Brick extension to home from a bar.

In such situations, an extension of bricks (or logs, frame, blocks) is performed as an independent structure, which is erected close to the country house, but there remains a small technological deformation gap between the two structures, filled with thermal insulating and waterproofing material. From brick or blocks often make a garage, workshops and any other business buildings reliably protected from all sides. Of course, the brick garage will not provide the proper level of heat insulation, so the insulation will necessarily need.

How to attach a veranda, canopy or porch to a wooden house?

Not all country households need a garage, a new residential room, a kitchen or a barn. That is why they choose a canopy or terrace as an extension, which easily join the bruus and do not require documentary, in contrast to capital designs. Naturally, all work on the device canopy or veranda can be made with their own hands.

To begin, it is necessary to install two vertical racks (they can be made of timber, metal pipe, concrete), which are inserted into the pre-prepared pits of the corresponding depth (75-125 cm). Immediately after installing the pens, the pit is necessarily filled with high-quality cement mortar. After pouring the solution on the racks, horizontal beams are stacked, the fastening of which is carried out to the cut, taking into account the slope of the canopy. Then on the beams that perform in the quality of the rafted, the wooden doom is mounted. And only after that, a suitable roofing material is installed on the crate.

Ontulin, metal tile, slate, polycarbonate, and any other types of traditional and modern roofs can be used as roofing material.

No foundation for canopy is not required. If the terrace device is assumed, then it is best to make a separate foundation.

Wooden extension is the most convenient way to increase the area of \u200b\u200bthe country house without unnecessary costs. If the size of the site allows you to additionally build another room, using any finishes. An extension of wood will be harmoniously looked with a log, and with brous house, If you wish, you can use any facing options. It is possible to build an attraction yourself, but in any case, this work requires careful planning.

Design an extension

The first question to which the owner must answer: why do we need an extension, how is it supposed to use it? If it is planned to be turned into heated residential premises, it will be necessary to solve the issue with additional insulation and gasket of communications. This question must be thought out in advance, otherwise there may be a lot of problems.

If the construction of the terrace, gazebos or, for example, the unheated garage, work will be easier. It will be enough to calculate the size and decide on the type of future attachment, finishing and other issues. Lighting issues should be thought out: even for the terrace, it is better to consider additional electrical wiring.

An extension of timber breed house Can be performed in several ways:

Three walls of the extension can be made in the form of a church, fastened with a wall of the building. To do this, various devices are used: corners, metal brackets, ducts, etc.

In this case, it is important to provide for the possibility of shrinkage of the bar, which will differ from the shrinkage rate of the log: for an extension it is better to acquire the already dried bar, whose shrinkage will be minimal. A timing extension looks harmoniously by any wooden house, the exterior cladding is not always required.

Another solution is a skeleton extension. In this case, only the wooden framework of the structure is made from the bar, and an OSP plate with insulation can be used for the walls of the walls.

In this case, there are no problems with shrinkage, but the chipboard will need to be scented using any modern materials. The frame structure is more difficult to build yourself, you will need to attract assistants.

A variety of frame extension can be called a closed terrace for which the capital walls are not required. The fence can be folded from the bar, the roof is installed on the support pillars.

The terrace will be a continuation of the house and a great place to relax on fresh air. It is possible to separate it as if it is possible: as an outdoor coating, you can use a terraced board or special moisture resistant laminate, fencing and reference pillars can be painted in any color.

Attaching an extension to a log house

How to tie a brusal extension to a log house? This is the most difficult stage, as you actually connect two buildings with each other. The construction uses two main options for this compound:

A common solution is an attachment for metal brackets. It is used if the bus is shut-off in an old house, where in the main building the shrinkage has already ended. Brusade walls are attached to log braces, the connectors should be processed and closed with a nickname - a regular board so that it is not visible.

During the first half of the year, the timing extension gives a shrinkage, and as a result, the brackets may be eliminated. They are taken out, and then set to a new place so that they again ensure the reliable fastening. Usually, it is not necessary to repeat this procedure, the building will already be prepared for finishing and operation.

Another option is the mounting of the bar with the help of the corners that can be purchased in the construction store. A bus force to a log house is attached with galvanized corners with a shelf length of at least 63 mm using self-samples. It is important not to twist the screws tightly: they must have a slight backlash, which will allow you to compensate for the progress of a bar during shrinkage.

It is important to ensure not only the connection of the walls among themselves, but also the foundation. It is recommended to build the same foundation for an extension that was used for the main house.

If a ribbon concrete base is used, the new foundation is attached to the old with the assembly. The correct connection will allow to compensate for the soil movement, and the extension will be reliably tied to the main building.

Frame extension nuances

The arrangement of the frame extension, as a rule, takes a much less time while gives a very good result. An extension to a log house from a bar will weigh a lot, because for heated room, the minimum thickness of the timber in the logging is 150x150 mm. The frame structure can be made multi-layered: the outer and internal lining of the walls is made of chipboard or PSS plates, and the space between them is filled with any modern insulation.

Frame technology allows you to make a light and inexpensive extension that will be well protected from the cold. An additional plus - you will not have to wait for the completion of the shrinkage, you can immediately move to the finish.

A timing extension requires additional external or internal insulation, so no additional costs do not succeed. Frame walls can be fed by anything: for exterior decoration The block house is suitable, you can use the usual lining or any type of siding.

An important question is the cost of an extension to a wooden house. It is necessary to take into account not only the cost of wall material.

It will require a roof for which it will be necessary to build slinge system With insulation, and then lay roofing material. The estimates include doors and windows, decoration Materials etc.
