A few words about the production of logs
As a matter of fact, this material is made from a milled log that has been thoroughly processed on special equipment. Depending on the type of machine used, it can be given a different profile. The whole production stage is conditionally divided into 6 steps:
- sorting logs by diameter;
- feed to the cylindrical machine;
- cutting on a detail of the house with the help of chain and circular saws;
- in the chopping machine comes parts for corner connection - "bowl";
- treatment of all parts with antiseptic;
- packaging in special packages for further transportation.
In addition, various kinds of machine tools can be used for machining - through-type, turning-milling( positional), centering, broaching machines and others.
Round log: pros and cons
This material has both its pluses and minuses. Advantages of rounded logs, first of all, are completely ecological production of .During the manufacturing process, no chemical adhesives are used. Secondly, houses made of round logs -
The material itself has a high ability to store heat and, moreover, a sufficiently low thermal conductivity of .Fourthly, you can connect log elements at any angle .This gives truly magnificent opportunities for the implementation of any wooden structures.
Fifth, significantly saves money and effort when assembling , as logs arrive at the construction site with already prepared canals and cups. All you need to do to the masters is to collect them. Sixthly, the material has an aesthetically pleasing appearance and does not require further decorative finishing of the .
The disadvantages of cylindered logs are related to the fact that the uppermost protective layer is removed during processing. Therefore, the following drawbacks appear: shrinkage of the first floor of the structure on average by 10-20 cm;the appearance of cracks, twisting of logs in a spiral under the influence of wind. In particular, the first drawback is noticeable. The shrinkage lasts from 6 months to 1 year, and during this period it is important to ensure a sparing operation of the house. Undesirable use of heating appliances.
How to determine the quality of logs?
The quality of the logs directly depends on the machining mechanisms, as well as on the qualifications of the employees who carry out this work. So, let's describe those moments, which should be paid attention when buying. First, all parts must be made from the same wood. Secondly, the presence of rot, cracks and chips is not permissible on products. Thirdly, the material must be perfectly even, curvature is excluded. Fourth, the deviation in diameter and length between logs can exceed a maximum of 2 mm.
Fifthly, on each product there should be a marking confirming this or that specification. Sixthly, the logs from round logs are made only from growing( not dried up before the felling) trees. This is necessary in order to ensure the natural moisture. Seventh, the entire surface is treated with an appropriate antiseptic for longer operation. If all these conditions are met, the life of the rounded log can be more than 20 years.
