Today, many city dwellers dream of a country house, and if there is an opportunity to acquire real estate outside the city, then usually the most harmless natural material is used for its construction - timber. But in order for the housing to be warm and comfortable, you need to know the features of working with this material, in particular the manufacture of corners. If this operation is not performed correctly, the building will begin to freeze in winter, the wind will penetrate inside it, and the walls will freeze as a result.
To eliminate all these and many other troubles, there is a special connection of individual elements on the corners of the house, which is called a "warm corner". This is the name of the method by which the timber is sawn. Due to the peculiarities of its manufacture and subsequent connection, there are no through slots. There is more than one type of "warm corner" connection, and further on each of them in more detail.
Straight Spike
Usually used in the construction of buildings of small sizes, in which the length of the wall and timberis the same. The connection is quite reliable and able to withstand all the loads for quite a long time. Importantly, during shrinkage, the load is distributed equally over the entire surface of the joint, which keeps its weak part intact.
There are several rules that must be observed when making tenon and groove elements. In size, the spike should not be long or wide, since its size affects the dimensions of the groove element. If the spike turned out to be thick, then the groove element must be made correspondingly wider. Because of this, the weak point of the beam, on which the groove is located, becomes vulnerable.
Half dovetail
Features of production - sawing of a cone-shaped spike. The warm corner of a log house of this type has a connection similar to a straight spike, but is highly durable. This is because the cone-shaped notch prevents the bars from coming apart and keeps them securely in place. This connection option can be used during the construction of structures with a wall that is longer than a beam.
The complexity of the above docking methods is the same: in this case, you can use the “warm corner” template or do without it. Even experienced professionals are unlikely to find differences in their performance.
The width of the dovetail spike should be about 5. If it is wider, shrinkage will occur unevenly and cracks will occur in the beam where the groove is located.
Angle Spike
The feature of the technology is the production of a triangular spike. The warm corner of a log house has the following advantages:
- No gaps.
- Full sealed.
- Easy to make, similar to both methods above.
Unfortunately, this method is not popular because it has less strength than the dovetail connection.
All the described methods have almost the same indicators of heat retention, but the “half swallow tail” method is the leader in strength.
Connection "in the paw"
In another way, this option is called "half-tree". Due to the presence of a through gap, this option is not recommended for use in the manufacture of walls of buildings. Ability to use: making the top harness and the first wine - it is quite acceptable for these places, as it is considered the most practical.
When building log houses, experienced professionals do just that. The first and last screws are connected using the “half-tree” method, and in the manufacture of the rest of the building, the “warm corner” method is used. This makes the connection very strong.
Connection Benefits
- Can be used for the construction of structures for any purpose - for housing, baths, outbuildings.
- Closed way provides protection from the weather.
- Due to the absence of drafts in the house, comfortable conditions are always maintained.
- Easy sawing allows you to quickly build buildings of any size.
- Material is used sparingly.
- With accurate marking and high-quality cutting of the shape of the grooves (observance of the accuracy of geometric shapes), the elements will be connected very tightly, providing an ultra-reliable monolithic structure.
- Because the "warm corner" method does not involve the use of additional fasteners, construction costs are significantly reduced, and the design itself is easy to manufacture.
- Since the preparation of materials takes place in advance, the construction process itself takes place quickly, without loss of quality indicators.
- Most importantly, the finished structure is aesthetically pleasing and looks neat, so the house does not need additional exterior decoration, which also saves money.
Flaws
The only minus of the “warm corner” joining from profiled timber is the possibility of cracks appearing on the element where the groove is made. This happens when the work is done poorly. To avoid this, when creating an order, it is imperative to specify how the connection will be made and whether the team has experience in such construction.
