Wooden baths and residential buildings are very popular today. Their construction is not suiced, but if there is a sufficient number of assistants, there is no need to hire a team of specialists. You can purchase a ready-made household complex and fold the house on your own.

Before starting construction, it is necessary to study methods for connecting logs or timber, as this is one of the main operations. It is performed in the following cases:

• length extension (in case standard logs are not enough);
• hire corner.

There are several ways to connect. Consider their main techniques.

Types of Brous Connection in length and corners

Requirements for compounds

First of all, you need to know what qualities every connection should have.

1. Strength: The bars connected by any way should withstand changes in the surrounding temperature and humidity without the formation of cracks and splits. It is best to carry out the deformation of the bars dried up to 20%: their internal voltage is less than that of the material of natural humidity.
2. Sealed: connections of elements should not be airproof. A draft in the dwelling should not arise due to the resulting gaps. The latter will be less in complex constructions of compounds.

Advantages of corner connections of timber with the residue

The connection of the bar with the residue in the corner has the following advantages:

1. Absolute impermeability to air.
2. Connection reliability: no additional fixation is required, since the lower crowns, pressing the lower, reliably fix them. The design is able to withstand even the middle force earthquake.

Methods of corner connections timber

The following methods for connecting the bar in the corners should be selected.

1. One-sided castle groove. For such a compound with one side of the bar in the perpendicular direction, the grooves depth to the middle of the bar are cut down. Length and width of the groove should be the same to fit half of the attached timber. Such a design will be even stronger if applied to the additional attachment.
2. Bilateral locking groove: such an angular connection of the bar is performed by sampling the grooves from below. The depth of the grooves must correspond to 25% of the thickness of the bar, the width is the same. This compound is stronger because two adjacent bars are fixed on both sides. This practically eliminates the shifts and deformations when the temperature and humidity is changed.
3. Four-sided locking groove can not be described unambiguously: the advantage of a durable and hermetic compound is "compensated" by the complexity of the processing of the bar. The grooves can be filled with special machines: it will make the connection even more complex, asymmetrical.

Corner joints of timber without a residue

Such a connection is characterized by high economy, as the bar does not protrude beyond the outer contour of the walls of the structure. The disadvantage of the method is less strength and tightness.

Methods for connecting timber without residue

1. Jack connection: In this case, the ends and edges of the timber are not processed at all. Building material is placed so that whole bars are located on top and bottom of the link, that is, "knitting" was performed like brickwork. Additionally, the bars fasten with steel brackets, plates and brazers. Despite the simplicity of installation (you can do without carpenter tools), this method is better not to use the house. The jack is justified when the utility facilities are erected.
2. The connection on the knaps is a particular case of jacking, but with some changes. The end of one bar and the conjugated surface of another is processed in such a way that you can insert the key between them. This item will make the connection stronger and tightly, but only in one direction. Another direction is not protected as before. You can avoid this by giving a key of a swallow tail: in the middle of a narrow part, to the edges expanding. This complicates the process of making the key and grooves for it.
3. The combination of the bar in dragged prevents the ends of the mating bars to half the thickness so that the docking occurs is tight. The reliability of the compound is provided by copper. The disadvantage of the method is the high probability of formation of grooves after a shrinkage of the material, so after the construction of a log is performed by cachatka. In order to make the connection more reliable, it is strengthened with a key. Another embodiment to the floor of the tree is the docking "in the paw". At the same time, the edge of the bar forms a complex shape that impedes the displacement of the upper crowns relative to the lower.
4. The connection in the indigenous spike (another name is a warm angle) effectively prevents the wall shift and the occurrence of drafts indoors.

Technology for the preparation of timber

The whole process of preparing timber to the compound can be divided into three stages.

1. The edge of one of the connected bars is trimmed so that a spike is formed, the length of which is equal to 1/3 of the thickness of the bar. The shape of the spike is rectangular, some extension to its edge is allowed.
2. On the second (from the mating bars) is prepared by the corresponding form of grooves. Small gaps are allowed: they will subsequently be sealed with a pacle, hemp or jute.
3. Spikes are inserted into the groove on top, and then the BRUSEV connection is strengthened by molecules.

Direct connections Bruus

In the case when the length of the wall exceeds the length of the bars, they need to splicer. At the same time, the requirements for the quality of splicing are the same as in the case of an angular connection - strength and tightness. They are achieved as follows.

1. In order to prevent the displacement of the bars, they fasten them with a key. This item is used in conjunction with a sealing material that seals the connection.
2. Compound by the method of indigenous spike is no less effective than using a key. In one of the bars, in the middle, the groove is healed, in which the corresponding shape of the spike should be included. For sealing also use felt, packle or jute.
3. The method of oblique lock is the most difficult for execution. The compound occurs through a large area (at least two sections), which practically eliminates the deformation during the shrinkage.

Installation requirements:

1. The length of the bellows should be at least 4/5 widths of two crowns. Often, three bars are connected by one brazen.
2. The diameter of the bellows should be within 25-30 mm.
3. Points of connection of the BRUSEV brazen should be at the minimum distance of 1.5 m and necessarily - in each corner.
4. Begroes should be shifted horizontally in a checker order so that they coincide from the row to the row.

Coupling logs

The construction of log cabins using logs is more common than when using a bar. The connection of the logs at the same time has technological differences. Requirements for compounds former - strength and tightness. Consider the main methods for performing connections in length and in the corner.

The method of the angular connection with the residue "in the region"

You can connect with the balance of the log in the Siruba in any of the following ways:

• in the region;
• in chop;
• in the hodge

The first method ("in the edge") or "in the bowl" is the most simple. At the same time, the log is prepared in the form of a bowl. Its sizes should be such that the joined login firmly fit into it. Accordingly, the transverse log should have a bowl or "edge". The angular compounds "in the Obla" are divided by the type of execution for options:

• in Polterev;
• audio comb;
• in Kurdyuk.

The most accessible performed is the bowl in the floor of the tree. When laying logs, it is necessary to consider the following.

1. The logs will be laid tightly, if except the cutting of the "dom" at the top cut out the longitudinal groove.
2. The grooves fill the flanctin: it will serve as a heater.
3. Laying the logs of each next crown is made after fixing the transverse logs.
4. The strength of the structure is achieved due to the berthings connecting the upper and lower logs. The impudent is called a long wooden key of a round or rectangular cross section.

Compound logs "in Kurdyuk"

The connection "in Kurdyuk" is a complex variant of the method "in the region". The comb in this case is performed by an oval form, and at the bottom of the bowl, an additional protrusion is set up, which should navigate along the log. In the lower part of the recess is made by a special excavation for Kurdyuk.

Coupling logs "in chop"

This embodiment is performed similar to the methods described above. The difference is as follows. The bowl is cut down at the bottom of the log (with the "In the Obla" method - at the top). For this prepared an angle for laying a log. The end of the previously stacked logs need to lie down (in this - the essence of the method).

Connection "in Okryp"

At the same time, the method in the upper and lower part of the log (at the scene) is prepared direct excavations, the depth of each - ¼ of the diameter is prepared. The method is convenient for use if it is impossible to apply other ways to connect logs.

Complete logs in corners without residue

In this case, the method of compound is missing part of the log, protruding for the external perimeter of the wall. For a reliable connection, "Nice" is needed: the ends of the logs are fixed with spikes. So that the "quiet" was not blocked by the wind, the horizontal planes of the louds are performed by inclined. This compound is called "Lastochka Tail": a wedge-shaped part of one log is encouraged between two inclined planes. In the event that the wall should be launched to the wall, the T-shaped connection is performed. The end of the log of the partition is attached to the shape of a truncated cone, at the base of which - the square. The external part of the cone is expanded. In the appropriate part of the wall, the similar excavation is cut down. The connection will be reliable due to the encoding of parts.

Coupling log

The connection of logs in length involves the use of one of two ways:

• in paw;
• dovetail.

Logging technology is the same as when connected in the corners. The difference lies in the orientation of the preparation of the recess. Reliable fixation is achieved with brazing. Important: Log connections in neighboring crowns should not be directly above each other: the displacement is performed in a checker order.
