How to make the openings in the frame house?

When mounting frame house a standard spacing between vertical supports up to one meter, depending on the width of the insulation. The width of the window is most often 120 - 150 centimeters, the average width of the door opening - 90 cm. Window opening will not fit between the frame uprights to the same window - rather heavy design, he needs additional support at the bottom of supporting its weight. The doorway is experiencing heavy loads due to the ongoing operation of the door, there is also a need to strengthen the opening.

In a situation of additional loads on the openings, it is necessary to increase the distance between the vertical supports vnutristenovymi. However, such a large section of the wall without a jumper lead to imbalance of the building load, reduce the reliability of the power and quality of the carcass trim attachment. This raises the risk of destroying buildings. To avoid negative consequences in the construction of a frame house used special items for all types of openings.

What are the different ways of mounting openings?

For manufacturing apertures in a modern frame construction using two methods:

- Heather (North American technology).
- Rigel (Scandinavian technology).

Mounting bolts more streamlined than the headers, so the Russian bolt is more popular.

Heather mounting openings

North American technology involves the installation of a powerful beam mounted in the opening, which is called the header (header from the English word, which translates as "cap"). Heather becomes a bridge at the top of the opening. He distributes the common voltage transmitted from the design on the whole window assembly of the wall structure and on the roof.

To set the header in a frame mounted double, and otherwise triple vertical side racks, mounted support webs for the opening support. Dual rack mounted on the full height from the bottom to the top of the beam. Design complement semiproof frame having a normal step. They are attached to Hedera and connected to the top trim of all walls. The second part is connected polustoek lower jumper bottom of strapping frame. Door pillar is different from a window that is not set lower bridge and lower poluopory.

Bolt mounting openings

Rigel has a simpler and more rational design compared with Hedera, as it allows to do without separate additional constructions. Structurally crossbar and header similar in many ways, but there are a few features:

- an additional structural element that is placed under the upper strapping frame (bolt). It - set edge board that probroshena along the entire length of the wall.
- Each vertical stand crashes into bolt.
- No need to install some twin pillars that could be in violation of the technology a source of additional penetration of cold air into the room.

Due to the girder there is a possibility of installation of openings in any part of the wall without the threat of violation of rigidity. No additional semipermanent. If the length of the wall, the bolt joints of several boards.

In the next article we will discuss the installation of the roof.
