Log houses have a number of advantages in comparison with wooden log houses. Due to the fact that the timber has a geometrically regular shape (it is either a square or a rectangle in cross section), much more usable space appears in the house, it is much easier to calculate the amount of timber needed to assemble the walls.
To do this, you need to add the lengths of all the walls, multiply by their height and the thickness of the beam, consider an example of the formula:
V timber = wall length X wall height X timber thickness
We get the number of cubes of timber needed to build a house.
The correct calculation of the beam on the house
Calculate the required amount of timber per house house 6x9, with a fifth wall, 3 meters high, from a timber 150x150, for this we add the perimeter of the walls, not forgetting the fifth six-meter wall 6 + 6 + 6 + 9 + 9 \u003d 36 running meters, then multiply by floor height (3 meters), 36 linear meters. m x 3 meters = 108 sq. meters, in order to get cubic meters, we multiply the resulting area by the thickness of the beam 108 sq.m. x 0.15 \u003d 16.2 cu. meters.
That's basically all, now it should be clear to you how to make the correct calculation of the necessary timber for the house, according to the above described scheme, even a schoolboy will figure it out.
Now let's talk about how houses are assembled from a bar
On an already prepared foundation, we lay in 2 layers any waterproofing material, such as roofing material or roofing felt. Mortgage boards treated (necessarily!) with an antiseptic are laid on top. These boards serve as a protective buffer between the foundation and the first row of timbers. If during operation it rots at the base of the house, then these will be the embedded boards (they can be replaced), and not the first layer of beams.
Laying the first crown
The next step is laying the first crown of the building. The main thing here is to carefully observe the dimensions of the building along the axes, the horizontal level and measure the angles planned by the project. Here it is also necessary to decide in advance which angular conjugation for the beam will be used when laying it.
The photo shows the laying of the first crown on the foundation The corners are checked with twine stretched diagonally from corner to corner and its length is measured. Then also stretch diagonally between the second pair of corners. If the distance matches, the next crown is laid. If there is a mismatch, the distance is corrected. In professional construction organizations, for these purposes, they do not use improvised means, but special high-precision engineering tools.
Before assembling the first layer of timber, one of the following types of wall corners is selected:
- assembly in half a tree;
- assembly in dressing with a root spike;
- dowel assembly.
Laying subsequent crowns
The second and subsequent layers of the beam are interconnected on wooden pins (dowels), which are a wooden rod, thanks to which the crowns are attached in height. Such fixation excludes displacement and buckling of the building material during shrinkage.
Ways of connecting and adjoining beams The hole for the dowel is drilled a few millimeters in diameter larger than the dowel itself, so that the beam, during subsequent shrinkage, can freely “walk” along the dowel, thereby preventing the formation of cracks.
