It is easier to install a log house from a profiled beam from a ready-made kit with sawn cups. Cutting cups is carried out according to the project of a house or a bath. On sale you can find ready-made kits or order sawing bowls from specialists for your project. You can cut the cups with your own hands, but their design will be simple. For cutting use a special tool - "cup cutter". The better profiled timber with cups from the manufacturer, the design of various types of saws and the features of making your own hands in one article.

According to their shape, cups on a beam are distinguished into simple ones that can be made by hand and complex ones with a special labyrinth. Complex ones can be made using a cup cutter, as they have a lock to save heat. A thermal lock makes the connection as tight as possible and the joints of the timber not only look aesthetically pleasing, but also inaccessible to the penetration of wind and cold. According to the shape of the connection of the profiled beam with the cups, the connections are divided:

1. In "oblo".
2. In a "cup".
3. "Dovetail".

The first two compounds with the remainder, the third without. Connecting the corners of the house with the rest has a number of advantages:

1. The corners are warmer.
2. Facade aesthetics.

The cons include:

1. Material consumption increases.
2. It is difficult to perform additional insulation of corner joints.

A bar with sawn cups is suitable for connecting with the rest - “into the oblo”. It is his pretexts to consider our readers.

What are the pros and cons of a warm corner

The connection of the corners of a house made of profiled timber with the rest is called a “warm corner”. It was formed due to the lock connection, which reliably protects the corners from freezing. Cupping is not always the most effective. Since the profiled material of natural moisture shrinks and dries out, a void appears between the bars, which cannot be additionally caulked. Problems can be avoided by using profiled material of chamber drying or glued. It is important to know a number of features before choosing a sawing into a manual or factory cup:

1. Bowls sawn on machines can only have certain sizes, since the settings are not unlimited.
2. The manual way of sawing cannot be perfect, as there is always an error during work.
3. An experienced craftsman can make bowls no worse than any factory ones.
4. When sawing in factories, you still have to adjust the corner joints, since the timber can dry out or, on the contrary, gain moisture.
5. Factory cutting is performed with a margin of 1-1.5 cm; during manual cutting, you can adjust and fold the timber tightly (in an interference fit).

The main difference between mechanical and manual sawing is the complexity of the thermal lock. It's nearly impossible to do it by hand. But the factory one is also not always of high quality and ideal. Drank cups depends on the quality of the machine and the cup cutter. You can use a cup cutter even at a construction site, as there are massive stationary and small mobile machines. The shape of the cup, the depth and angle of the cut depend on the choice of machine and nozzle. Corner cutting is necessary for easier corner laying.

How a cup cutter works

For sawing bowls by the stationary method, powerful electric milling machines are used: Interskom FM-62 / 220E, AEG 2050, Makita 3612C, Felisatti RF62 / 2200VE and others. Plates with cutters for sawing are located in the design of the machine. The edge of the milling cutters is sharp and rotates when drunk. When rotating, the cutters receive a large load, in order to reduce it, the plates have an inclination. The plates can be removed and inserted into place, securing with a special screw. Cutters for sawing bowls are mounted on a special frame that is movable and adjusts the length and width of the bowl.

Rising and lowering the cutter makes it possible to drill the required depth. The complexity of the lock depends on the model of the machine and the installed cutter. The mobile milling machine is installed directly on the profiled timber in the place where the bowl was drunk and fixed with tessellates. During operation, the frame moves across the beam, which makes it possible to work with a beam of any section. In this case, the groove is obtained in the required dimensions according to the given scheme. The main thing is not only to correctly install the cup saw, but also to calculate the place washed down. You can see more about how they work on a cup cutter in the video:

Where is the bowl washed down on a beam

Corner joints in different sections of the beam are performed differently. It is necessary to calculate the place of the cup so that the material does not become brittle and does not crack when laying the walls of the house in the corners. Washed down can be calculated using the standard formula: H \u003d (B + c): 4 (H is the thickness of the groove of the profiled material, B is the height of the selected beam, c is the height of the existing groove or spike at the profile. For example, take a profiled beam with a simple locking connection of 10 mm, section 200x200 mm Insert the values ​​into the formula: (200 + 10): 4 = 52.5 mm This will be the size of the depth of the gash.

1. The middle of the gash is marked and an incision is made along the borders to a depth of 10 - 20 mm.
2. The cutter is lowered onto the sawn grooves and start working at the previously calculated depth.

Judging by customer reviews, ready-made factory cups do not always fit in size during assembly and they still have to be finalized. To simplify the work, you can buy a manual cup cutter. The price of a typewriter starts at 35,000 rubles, but by purchasing a bar without cups, you can save. They use a manual cup cutter right during the assembly of a house or a bath from a profiled beam. The drank can be measured right on the spot and adjusted to the desired shape.

In this case, the connection to a warm corner is more hermetic. If the production of profiled timber is small, then it will be more profitable to purchase such a hand tool. Moreover, you can perform work of the same quality as on a powerful milling machine. Depending on the type of frieze you choose, you can cut the cup in different ways. The number of cutters depends on the brand of the cup cutter and its power. The more feathers in the configuration and the higher the power of the equipment, the higher the price of the cup cutter.

Types of cutters and corner joints that they make

From the selected shape of the cutter, a different corner connection of the profiled beam is obtained:

1. Four-sided bowl. The connection is made on a profiled beam with one rounded side - a block house or with even ones. Reminds four-way connection in the corner laying logs with the rest. A cylindrical end mill is used to make the connection. The side parts of the bowl are obtained according to the template, which is fixed to the material with laces. The cuts are straight above and below. The beams fit exactly into each other.
2. T-shaped bowl. This angle is called "dovetail". The cutter has a special shape with a sidecut. Machines on which such cutters are included: Brussivit, Euroblock, Craze, Bluk. The bowl is made in two steps, details can be seen in the photo.

Price for drank cups

The price for sawing bowls in a profiled bursa depends on the complexity of the design, the section and type of timber, the complexity of the design of the house. You can buy a profiled beam with cups as a ready-made kit at any large construction company that manufactures the material. In large cities, the price differs little, we calculated the average and present it in the form of a table:

You should not expect that when ordering bowls from a construction company, you can get an impeccable material. The human factor has not been canceled. The only thing worth overpaying for is the complex shape of the bowl for a warmer corner connection.

- this is a log house with releases, when the logs go beyond the log frame by 30-50 cm. The place where the logs meet in the log house is called the "lock", where they are fastened together by cutting in the log, made in a special way. The lock was cut in the form of a semicircle, according to the shape and size of the log that will fit into this groove, resembling drinking dishes in configuration, therefore, in the everyday life of carpenters, such an angular connection has been called “in a bowl” since time immemorial.

A log house without releases is a log house where the corners of the house are even, without protrusions beyond the contour of the building and have a special shape in the form of a trapezoid or dovetail. The carpenter's term "the corner of the log house in the paw" also goes back deep into antiquity, when Russian architects cut huts, wooden estates and towers with only one ax, erecting real works of wooden architecture.

There is nothing in common with a real bowl in a timber castle, it is of direct shape, because. the beam itself has the correct geometric shape, unlike a semicircular log. Houses from a bar into a bowl are of industrial production, the so-called. "constructors" and manual, when a team of experienced carpenters at the construction site erects a log house from a bar and manually makes a cut into the bowl in each bar.

A log house from a bar “into a warm corner” is built “without a trace”, when the lock on the corners is cut out in a way, in the terminology of carpenters, referred to as “half-dovetail”.

2. Profiled timber with industrial production cups

Mechanical bowl sawing has its pros and cons.

In production, the lock "with the remainder" is made on a special milling machine. In the design of the machine there are plates with cutters, which have sharp edges, rotating, they cut out recesses in the wood of the desired shape and configuration. The cutters are removable, after sharpening they are returned to their place. The plates are mounted in a special movable frame that adjusts the length and width in the bowl lock being made. The cutter blades are raised and lowered to create the required depth of cut in the timber. The level of complexity of the lock, which can be performed mechanically in production, depends on the model of the machine and the milling plates.

The main advantage of the production of profiled timber with cups is its speed. The mechanical work of a special milling machine makes it possible to produce the maximum amount of finished lumber building material in the shortest possible time.

Theoretically, the manufacture of a profiled lock into a cup on a machine should occur with maximum accuracy, in fact, this is not always the case. Building materials do not always turn out to be perfect, sometimes they have to be “brought to mind” on the spot manually.

The most complex configuration of the bowl is considered to be the connection to the “labyrinth lock”, when the cups cut from all sides are offset on both sides. With this arrangement of the lock in the timber, it is considered impossible for air to enter from the outside.

In the manufacture of a “labyrinth lock” on a milling lock, inaccuracies sometimes occur, gaps in the mechanical method of manufacturing this most complex type of lock happen up to 1-1.5 cm, which does not happen to experienced carpenters who make this type of lock manually.

3. Profiled timber with handmade cups

Individual work with a cupped profiled log house, when carpenters manually build a specific object, can be compared to the work of a fashion designer. The manufacture of a profiled bar with a cup in an industrial way can be equated to the work of "ready-to-wear", i.e. consumer goods of mass production.

When assembling a house from a profiled beam into a cup from a production designer, carpenters of medium qualification most often work, who do not have complex manual skills.

Many manufacturers do not undertake to make log cabins with it because of the complexity of manufacturing bay window corner joints on the machine and offer their customers a frame view of this architectural element in a wooden house.

Experienced carpenters can manually cut a bay window from a bar with a special corner joint in it.

The Chukhlomskaya Usadba company builds constructor houses with profiled beams in a cup. But our special pride is the carpenters, the descendants of the architects who built, and in Russia back in the century before last. Our carpenters own the secrets of their craft, which were passed on from generation to generation by their great-grandfathers, grandfathers and fathers. They are able to build not only houses from profiled timber with cups, but also cut log cabins from solid logs, which is considered the highest qualification of a carpenter.

Therefore, if you want to build a house from a profiled beam with cups, contact the company "Chukhloma estate", we will build you a house, even from a designer, even a hand-cut "haute couture" according to an individual project.

Projects of houses from profiled timber with cups:

8x11 m 1 515 000 rub.	12x8 m 1 776 000 rub.	10x11.5 m 1 700 000 rub.
8x10 m 1 368 000 rub.

Profiled timber is becoming increasingly popular. The configuration of its profile protects the walls from deformation during the shrinkage process and reduces construction time. In order to minimize the influence of the human factor during the assembly process, they use a ready-made constructor for a quality house - a profiled timber with cups.

For designed buildings, cutting cups in a beam is an important stage at which a castle design with a windproof labyrinth is created. There is one-, two- and four-sided locking groove. To build a house, 2 technologies are used: assembling a ready-made kit - it provides for the factory production of cups and cutting the cups directly at the site of the construction of the house.

Factory production

Cutting cups is carried out for the production of sets of finished buildings: houses, baths, arbors. The set, which is obtained as a result of processing and cutting the timber strictly according to the developed project, is assembled quite quickly on site.

This is due to the high accuracy of woodworking equipment and the developed drawings. After assembly, they get a house with perfectly even and warm walls that are not blown through and do not need additional finishing.

GOST 30974-2002 provides for a maximum deviation in the size of a milled beam of no more than 1.5 mm in width. It is difficult to obtain such accuracy without the use of automatic equipment. It takes about 1 minute to cut four cups.

Additional machining - milling - increases the cost of finished products. On average, this is about 2500 rubles. per cube m. Therefore, some owners, trying to save money, plan to cut the cups on the spot.

Cutting bowls in the process of building a house

The industry offers manual mobile cup cutting machines. Such designs can be used in conditions of small production capacities. Chainsaws are also widely used.

It takes 8-10 minutes to cut the bowls. As a result, assembling a house from profiled timber without cut cups requires several times more time than when using ready-made kits.

The quality of the assembled structure depends entirely on the qualifications of the craftsmen. This is exactly the factor that is leveled by the purchase of finished products that do not require significant fitting operations.

The cost of cutting cups

The price of finished products is affected by the moisture content of the material and its type (solid or glued beams). It should also be noted that products of chamber drying are more expensive than profiled timber of natural moisture. But dry material has two advantages: the formation of fewer cracks and the possibility of building a home decoration within one season.

The price for cutting bowls on glued material with a moisture content of less than 15% is 3000 ... 4000 rubles. per cube m. Data for an array of timber are given in the table.

At the end of the article

The use of profiled timber with ready-made cups allows you to speed up the construction process and guarantee a high quality result. But for these benefits you need to pay an additional price: about 2500 rubles. per cube m. Otherwise - when cutting cups on the spot - the result depends entirely on the qualifications of the builders.

Our customers, before the final choice of the project or the conclusion of the contract, often ask the question: “Which way of felling is better: in a warm corner or into the bowl for a house from a bar?

We immediately answer that both methods of cutting corners are windproof from the outside. The quality of the house, its reliability and ability to retain heat, are not affected by the types of felling: a house made of timber and into a bowl, and into a warm corner will equally warm you in winter.

Of course, provided that the felling is carried out by professional carpenters, subject to all the rules for assembling a log house from a bar.

Carpenters from the company "Chukhloma estate" have the necessary qualities and skill to cut a house from a bar with locks into a bowl or into a warm corner, as it should. Therefore, we do not face the problem of how to cut a log house - the choice is up to the customer.

The difference in locks in a warm corner and in a bowl lies in the external design and shape of the castle itself, in the price of a log house in a bowl and in a warm corner.

Let's take a look at what a corner in a bowl is, a warm corner, so that you decide which of the cutting methods to stop at, make your choice.

1.Angle into the bowl

The method of cutting corners or "with the removal" is the most expensive method of cutting. This is due, first of all, to the additional expenditure of timber during the construction of the house.

Corners into the bowl are protrusions of rows protruding 30-50 cm beyond the main contour of the log house, they intersect with each other in the lock knot and continue in the form of extensions.

Making corners into a bowl has been used since antiquity, when cutting. Carpenters with an ax cut grooves in the log in the form of a semicircle, in the shape of a log, so that the logs of the log house, stacked in rows, were fastened together in locks, crossing.

The shape of the castle in a log with releases, in the form of a semicircle, reminded the ancient carpenters of the shape of a cup, so the name of the castle in the log house at the corners came into use - "into the bowl" or "with releases", "with takeaways", "with remainder".

Locks with releases in a log house from a bar have nothing to do with the shape in the form of a bowl, because they are made not for a round log, but for a square bar in the section, but according to tradition it is called “into a bowl”.

The lumber "bowl" has a different configuration of the lock on the corners, this is the so-called. "Labyrinth Castle". The labyrinth lock has an offset on both sides, which ensures the stability of the log house due to these special offsets. The labyrinth lock also provides complete tightness of the closing of the beam at the corners, which excludes the ingress of air from outside.

Construction of a house from a bar according to the project into a bowl, washed down the corners into a bowl:

2.Lock a log house from a bar to a warm corner

The lock of a log house from a bar without outlets is called "in a warm corner". This method of cutting corners is also called "without a trace". In appearance, it is similar to a castle in a log house made of hand-cut logs, because it does not have outlets in crowns outside the walls.

A house made of timber is cheaper, because it consumes less building materials.

Making a castle in a warm corner occurs according to the principle "dovetail". At one end of the beam, a spike is cut in the form of a half-trapezoid, and at the other end, a groove for a half-trapezoid is cut. The rows of timber with sawn ends are tightly closed in the corners, thanks to the "thorn-groove" system. And so it is done on all four sides of the log house, from the first to the last crown.

"Dovetail" for a warm corner is made according to a single template, which is always at hand for carpenters. Such a complex closure at the corners and "flashing" of the timber in the rows ensures the stability and strength of the entire log house.

A well-made warm corner ensures complete closing of the beam in the locks and eliminates the blowing of a cold draft from the street.

Carpenters from the "Chukhloma Estate" are building a house from a bar for two families according to the project, the video shows how they drill holes for wooden dowels, make grooves in the wall "into a cut" and cut a lock into a warm corner in a bar, making spikes and grooves for closures:

3. Which is better: a warm corner or a bowl?

Both types of lock in a log house are reliable, keep heat well from the inside and do not let the cold in from the outside, thanks to their complex configuration: a “labyrinth lock” in a bowl and a “dovetail” in a warm corner.

A log house in a bowl with extensions looks more embossed. It looks emphatically stylish, in the tradition of making log cabins, when wooden houses were cut down with the help of one more axe.

A log house from a beam into a bowl does not imply additional wall cladding from the outside, because. offsets at the corners will interfere with this. Bowls on the corners are a sign of making a house out of wood.

But for corner offsets there is an additional consumption of timber, approximately one meter for each bar, so a house from a timber into a bowl is more expensive.

No additional building materials are spent on a house from a bar in a warm corner for the sake of "beauty", so its production is cheaper.

A log house with a warm corner is even at the corners on all sides, so it can be sheathed from the outside if necessary.

Thus, which log house suits you best, make your own choice: with bowls decorating a log house, but more expensive or with a warm corner - cheaper and allowing wall cladding.

Both methods of cutting corners are reliable and time-tested, which shows that in terms of quality characteristics, one is not inferior to the other.

Assembling a house into a bowl is very popular with our compatriots. This can be easily explained, the fact is that such buildings are distinguished by their environmental friendliness, good thermal properties and a long service life. But in order for them to be endowed with these advantages, you need to use the services of experienced professionals. The Dom iz Elya company has been assembling a log house into a bowl for many years, during which time our specialists have finalized the construction process from profiled timber to the ideal.

Connection types

The connection of the timber by this method, depending on the shape of the bowl, may differ. There are the following locks:

• Unilateral. This method of making a bowl is considered to be inefficient and the simplest corner connection. The bowl itself has a base in the form of a rectangle and is performed only on one side.
• Bilateral. The bowl is made at the points of corner joints, its depth is made equal to a quarter of the beam. To perform this work requires a master with a high level of skill. The corners of the log house with double-sided bowls have the same drawback as the previous view - they are blown through.
• Quadrilateral. This is the most perfect assembly of a house from a bar into a bowl, because it is characterized by insignificant heat losses through corner joints. It differs by cutting a groove on all sides, quite often there is a labyrinth-type lock (windproof), which has an alternation of bowl parameters.

Assembling a house into a bowl allows you to create country houses in a short time. If you use the services of Dom iz Eli, you can be sure of the quality of the work performed. All construction services are guaranteed.

Coniferous trees, such as spruce or pine, are used as material for the log house. It is very important when buying material to choose straight, even and not damp logs. If the wood is too damp, then when it dries, it will deform and cracks, gaps between crowns, etc. will appear.

Before starting work, the logs are prepared - the bark is removed from them, then the log is sawn from four sides and the resulting beam is directly profiled. To fasten the elements of the log house, wooden dowels, as well as metal studs and nails are used.

If you need a house made of profiled timber - the company "House from Eli" is waiting for you

The assembly of a log house into a bowl, made by professionals, will bring coziness and convenience to your life. Our specialists use only modern construction technologies, thereby achieving long service life and an attractive appearance of the building. Using our services, you can not worry about the freezing of the walls and drafts, as they simply will not be.
