Blockhouse: Russian, Norwegian, Canadian

According to the consultant site FORUMHOUSE Hermes-sz, you can argue about which of the houses - built from logs or cut down by hand - better. It's a matter of taste. Any competently constructed buildings made of solid wood - this is already good. But the person who decided on the log cabin with his own hands, causing a lot of respect. This article discusses the cabin log cabins, and their types: Russian, Canadian and Norwegian. Consultant tells about the features, advantages and disadvantages of wooden construction systems.

As felling cut

Log cabin - a chopped wood construction, built without floor and roof of the processed logs. One set of four elements interconnected by notching called crown. Felling home or baths It involves three steps: cutting corners, slots and shkantovku.

With the right technology logging log notching must withstand the load transmitted to them; their mating elements tightly against each other. With the construction of exterior walls carcass must be borne in mind that in the notching must not stagnate water.

For centuries wooden architecture developed and improved, and today there are over a dozen types of log cabin. However, the basic compounds of all logs - only two: a residue and without it.

Subspecies corner vrubok

Notching with the remainder

Known types of notching with the remainder:

• In the bowl (in oblo);
• The coir;
• In ohryap (in ohryapku);
• In the hook.

felling "in a bowl", or "in oblo"(Obly - formerly meant" round ") - one of the oldest connections. Its advantage is the stability: the side of the timber to protect the angle of log house from wind and rain.

Log structure "in the bowl" can be made in three variants. First - "vpoldereva": A bowl and a longitudinal groove cut down on one side of the log, the latter upwards. In two other cases, a groove along the beam is directed downwards and is cut on the side opposite the cup. The elements are connected by a left in the bowl zaovalennymi crest, repeating the shape of the longitudinal groove of the cross beam. The third option - "in the rump": In the cup is left additional projection which is directed along. In fact, that is placed on the cup bottom is a corresponding recess.

Notching "vpoldereva" - the most simple, does not require multiple kantovok logs and staples for their temporary fix. Later subspecies notching the lower position of the longitudinal slot requires removal of the logs to undercut longitudinal groove and fitting them together.

Unlike logging "in coir", or "in ohlupen"(" Ohlupen "- something closes hollowed logs) from the log" in Oblomov "is that the downward bowl is at the top, log rolls, which is like a" kills the "bottom. This compound, though difficult, but successful: no moisture gets into the cup as a result provides long-lasting preservation of the material.

notching "in ohryap» («in ohryapku') Is similar to the log cabin "in a paw", only the bottom and the top of the log, about a quarter of the diameter, make straight notches. blockhouse "to hook"The most durable and warm connection. This sophisticated version of felling "in Oblomov", when one half of the cup is selected in the bottom log, and another - on the top. Also made a radical thorn and dressing of the inner walls. This complex process requires high skills of a carpenter. In the old house so cut rich people, nowadays this type of cutting is popular thanks to smooth inner surface of the walls.

Felling without a trace

Known types of cutting without a trace

• In column (a Zabir);
• The paw;
• The net angle;
• The leg with thwarting.

blockhouse "in post» («in Zabir') Made of logs along with selected slots in which other elements are inserted horizontally. The ends are cut spikes corresponding groove.

blockhouse "in the leg": From logs sawn ends protruding beyond the wall, forming a corner with no residue. Ends at the junction in the wooden house podtesyvayutsya on both sides, the ends of the boards are usually sewn patch to protect against the weather. Cabin "in clean coal" do one of the following:

• Ends protesyvayutsya parallel top and bottom is removed by a quarter of a log.

• Horizontal plane makes with the slope in two directions, in the form of "dovetail": timber is firmly engaged with the adjacent, and this assembly does not allow him to wriggle out. This log cabin, due to insufficient insulation, mainly used for outbuildings.

cutting is used to more reliable connections "in the leg with thwarting": Make a small spike, placing it at the inner corner of the carcass at the bottom to the top of the plane - a corresponding groove. "Paw" is made in the form of a parallelepiped, and the spike has the same function as the cutting off when cutting corner "in bowl".

For all types of log walls angular vrubok maximum gap size should not be more than 0.5 cm - 'in oblo "and" leg "and 1.5 cm - in the longitudinal groove.

Russian felling

Chopping a log house from logs - traditional Russian craft, due to the richness and diversity of the building material - softwood and hardwood. Until now actively used in the construction. In Russian embodiment carcass assembled from round logs with a semicircular longitudinal groove and the crown angular compound "in oblo" - they could be at the top or bottom member. Improved embodiment has vrubka "in rump" or "bowl dark". On FORUMHOUSE can read more about log cabin in a "bowl".

Disadvantages of Russian way of logging: log shrink unevenly along and across the grain, after shrinking tightly sit in the wooden house. When reducing the beam diameter varies form connecting bowls - they open, becoming of semicircular - oval. Therefore, the design typically requires re caulking. Another disadvantage is that an unprotected heater, extending beyond the slot and cups, absorb moisture that gets into the joints and leads to rotting wood.

This shortcoming is not Finnish log cabin: Cabin similar to Russian, but mezhventsovogo slot repeats the outline of the bottom of the log is not completely as in the wooden house in Russian. It is made with a smaller radius or zaovalen - to top rested on the lower edges only.

Swedish log cabin today almost no use. Hermes-sz believes that this time-consuming and not very good kind of log cabin. Girth groove do as the Finnish blockhouse, trim the ends of a hexagon, a cup - trapezoid. In Russia, so we cut down, when he had to make beautiful corners.

Norwegian cabin or a house from the mast

Flitches prepared by removing the lateral surface of the log, removing bark from all surfaces and semicircular ostrugivaya manually. The thickness of such a timber is usually 15-20-25 cm. Carriage made of thick pine trunks, the minimum diameter of the cut in the upper one and a half times greater than the thickness of the mast. Scandinavian style requires the internal partitions and gables of the house of the mast, as well as powerful slegovuyu roof, covered with natural tile or layer of earth with grass. Cutting a log house from the mast to make the so-called Norwegian castle.

Norwegian Castle differs from the Russian cup shape: bowl - round, the castle - with a wedge-shaped profile. Norwegian Castle allows rod in desiccation of the wood sink in the wooden house and under its own weight log wedged in the notching.

The Scandinavian wooden house through the use of large-diameter logs is significantly less than the crown grooves, which can lead to dangerous from the standpoint of blowing and freezing places. Flitches "bursting" is stronger, but the locals believe that the cracks only adorn the walls of the house, emphasizing the natural material.

Canadian cabin

This logging uses a lock on the Norwegian round logs: in places vrubok downhill perform protesku top of the wedge of the log. The walls look solid array of gaps between the logs is not a cup - trapezoidal insulation in seams virtually invisible due to the shape of the crown of the groove, the edges of which fit snugly to the bottom log. So that the water does not enter the heater, it immediately undercut.

Canadian and Finnish logging of log houses do not require re-caulking.
