How to make jibs in a frame house? Step-by-step instructions + Photos and Videos Jibs in a frame house - installation technology, step by step instructions

Few know what jibs are in frame house. But even fewer people know in which cases they are needed and in which they are not, as well as what varieties are and how to correctly install them. This will be discussed in the article.

As the name implies, the base of the frame house is the inner frame ("skeleton") of the building. It is on this design that the durability and strength of the house largely depends, therefore it is extremely important to purchase only high-quality materials for the manufacture of a frame and to correctly assemble it.

Brief description

What are jibs?

Most often, coniferous wood is used for the manufacture of the frame, and much less often metal and hardwood. Glued laminated timber is ideal for vertical load struts. To distribute vertical loads, jumpers are made of boards.

The stages of construction of the frame are:

  • Laying the beams on the lower strapping and fixing them to the foundation.

  • Installation of racks.
  • Sets the top tier.
  • Fixing the frame.
  • Installation of ceiling beams and roofing.
  • Insulation.

  • Interior and exterior decoration.

The frame itself is a massive structure, which is made of high quality and durable material. So why carry out additional strengthening of the frame and can you do without it?

What are they for?

If you do not know how make jibs in a frame house, first, familiarize yourself with what functions they perform. In the frame, all parts are located perpendicular and parallel to each other, and therefore they may not always be resistant to lateral loads, for example, if there is "walking" of the ground, wind or snow. In order to give the necessary rigidity to the structure, jibs are built into the frame.

These are special diagonal elements that will not only make the frame more stable and stable, but will also hold the outer sides of the house.

If the frame does not have stiffening elements, it may lose geometry over time, and this, in turn, will lead to deformation of the internal and external finishing. With heavy loads on the sides, the house can even collapse. Less terrible consequences are the loss of heat due to the fact that the integrity of the insulation layer will be violated and the durability of the house will be reduced. In this case, the installation of jibs in a frame house will be justified, although it will entail additional costs of materials, money and time.

Please note, that sometimes instead of jibs, struts are installed between the struts, and this is less laborious. But such struts will give only vertical stiffness, and will not interfere with "folding".

When is installation not required? This applies to small structures such as toilets, garages and utility blocks. It is also possible if an external oblique lathing is used in the house. If the cladding material is strong and large, for example, strong plywood or OSB-3 boards.

How to install?

… permanent jibs

Now let's look at how to make jibs in frame house, which will be there permanently. Such stability elements should be inserted not only into external walls, but even into partitions. Ideally, the installation angle should be 45 degrees. But because of the window and door openings, you will not always be able to comply with this requirement, and then it is permissible to increase the angle to 60 degrees. Installation should be done from the bottom rail of the wall to the upper corners.

As a result, the stiffeners will form a right-angled triangle with a corner post. In the places where window and door frames are installed, it will be better for the jib so that it is directed from the corners to the openings, and then you can additionally fix the elements. For a snug fit, jibs should be cut into the frame elements, having previously cut out the grooves of the required width and depth. With properly mounted strength elements, everything will fit tightly to the frame and will not interfere with the sheathing.

Make at least two pieces on each wall and place them along the edges where the outer corners are located.

To stabilize the house in both directions on the outer wall, one jib should be made with a slope to the left, and at the opposite end of the same wall with a slope to the right. For ease of installation, the stiffeners should be located outside the walls, but if you recall the laws of thermal physics, it will be more efficient if you install them from the inside, since with this arrangement they will reduce the heat transfer of the insulated wall.

Important ! Fastening is done with nails, and in no case should self-tapping screws be used.

Occasionally builders make jibs from the remains of boards and attach them only where it is convenient, but this cannot be done. You should use boards that are at least one third of the total distance from ceiling to floor in length.

Also, the elements must be full-bodied and not have voids. The ideal option is coniferous wood boards with a thickness of 2.5 cm. Believe me, there is no need for more expensive and thick boards. Firstly, even this material will perfectly fulfill its functions, and secondly, the jib will cut into the frame, and the greater the thickness, the greater the risk of weakening the frame.

Make sure the boards you are using are well dried. If they are very wet, then when they dry in the future, the gap between them and the frame elements will increase and the rigidity of the structure as a whole will be broken.The insulation must be cut along the edges of the boards, otherwise air bags will form at the edge, and this also negatively affects the thermal insulation qualities of the house.

… temporary jibs

A temporary stiffening structure is usually installed by workers at the third stage of construction, if you do not plan to make a similar structure permanently. They hold the intermediate and corner posts together until the top harness is secured.

In addition, temporary structures are often used to level frame walls in order to avoid distortions, which can further complicate interior decoration.

How to make temporary stiffeners? First, align the corners with a level or plumb line. After that, you can overlay the boards and observe a step of 120-150 cm. It will be better if you do not save. We fasten the boards to the lower and upper strapping with nails, and before starting the sheathing, temporary elements can be removed.


Thus, for maximum durability of the frame, such stiffeners as jibs in a frame house are considered necessary elements for the entire structure. They should be made only from quality materials and in accordance with all the tips above.
