Installation of doors in a wooden house. What to do to avoid the wedge?

Installation of doors in any lumber house and the house of logs is no different. Door blocks can be assembled in a few months after the installation of the roof of the house to be shrunk. It is best to give the house to stand at least six months. Shrinkage can last up to 5-6 years, so the door installation technology for the wooden structure has a number of features. Specific rules for installation of doors are directed to ensure that the doors are not warped and is not jammed. Installation of doors should be made of two technologies:

- Casing bar.
- Obsada bar.

casing block

- First, you need to saw the planned opening, thus it is necessary to leave from the upper and lower crown no less than half the size.
- With the use of the router deepened groove dimensions 5x5 cm in the end adjacent to the opening of the wall. This slot should be done around the perimeter of the opening.
- The wall slot insert a bar of the same cross-section as the groove. The length of the bar - less than the length of the wall by 2-5 centimeters, depending on the degree of shrinkage of the house.

- If the house is made of logs, it is possible to use only one bar, but if the house is built from timber or logs, else the block (30-50mm) to be sewn to the bar, to compensate for the bending and twisting pressure. Spliced ​​all the elements using the compound nailed or using screws.
- The next step is to strengthen the bottom vraspor threshold, and on it - the board, forming a doorway. To increase strength, you can use the 100-millimitrovy bar.

Obsada of timber

- In the first phase scheduled Scrollsaw doorway.
- The ends of the wall around the opening Scrollsaw spike with the following dimensions: width - 50 mm, height of 35-38 millimeters. Top and bottom timber (logs) choose a chisel and chisel.
- picks up the timber from the timber even first grade, it is sawed groove size stud using the cutter.
- If the wall will sheathe clapboard, it is necessary to provide special relief grooves.
- Casing beam should be shorter prepared opening 20-50 mm, depending on the degree of shrinkage of the house.
- the bottom for fixing obsady selected slot is not less than 5 millimeters.
- Top timber casing is fixed board 50x200 mm, fixed vraspor. It is also possible to fix it in another way: the top board is installed on the two casing timber top.

Some practical advice

- Construction of a metal door has some differences. When installing casing of a metal door rail above can not be mounted. Enough to make the top clearance of 100 mm, it will not break the shrinkage of the house. Metal frame - solid construction to withstand the extra load. Side carriages are made on the size of the door frame.
- Thermal insulation made okosyachki tape tow attached staple gun.
- Cracks and gaps are insulated with foam.
- If the wall in place of the doorway led, it can be aligned using the timber for at least 2 meters in length, which should be attached to the wall on both sides. Fixing is done with long screws from the top down.
