At some point, it becomes clear that the foundation does not fulfill the functions that are required.And then it is necessary to raise the house on jacks in order to rectify the situation.

It follows that the building rises for the following purposes:

• underpinning;
• repair;
• replacing the lower crowns.

in urban planning practice, there is another reason that is necessary to lift the house - it is moved to another location.

preparatory stage

Immediately I must say that we are talking about how to raise a log, square log or shield house.The professionals do not recommend self-raising brick or frame houses.

It requires special techniques and equipment.Before the rise of the building, it is necessary to properly prepare.

first step is to carry out the necessary calculations.The meaning of the calculations to determine the value of buildings on the corner of the load.To do this, it calculates the total weight of the house and is divided by 4.

From this value it is necessary to choose a tie or a particular section of the board to be used as a temporary support.

In everyday practice, people are jacks of various types and purposes.They can be used to lift and transport vehicles, and wooden buildings.

In its Embodiment jacks are divided into the following types:

• screw;
• Hydraulic;
• paddock;
• rack;
• rhombic.

to lift the wooden structure is necessary to use a screw jack.All other types are not suitable for these purposes.To work is only one jack.If there will be two, the lifting process will accelerate.

lift the structure simultaneously with four devices is not recommended.In this case, an increased risk of misalignment of the building.

next step is to determine the location for the installation of the jack and prepare all necessary work materials and tools.

will need two metal plates to be placed under the jacks.Instead, you can use the trim board thickness of 5 cm or more.From the front of the house at the corners are fixed two rails.

They need to put a mark on which will have to be guided in the process of recovery.The most accurate mark made with the help of leveling.

If this device is not available, the layout can be made using a plumb line and a common building level.Reiki should be securely fastened.Tags are applied on the rail, and on the corner of the structure.

When the wall will go up, the value of the gap between these tags will be equal to the lift height.It is important to establish a jack.

It must be located below the lowest log and prop it.The photo shows a jack mounted under the lower beam of the wooden house.

Set it should be on the pre-compacted soil.But this can be difficult.Therefore, under the base of the jack is enclosed or board, or steel plate.

need to put a size of 15x15 cm steel plate under the head of the jack. The plate need to log not slipped from the head.

rise homes

Raise the house to the desired height convenient two jacks.Each of them is set under the corner of the house along one wall.When the installation is complete, you can perform a test recovery.

First one corner rises to 3-4 cm. After this action is performed a complete inspection of the entire structure.

If no change in the building structure has been detected, then the rise at the same height as the second angle.Again, you need to see the house from all sides.

In this way, the wall rises to the designated level.Maximum lifting height of one wall must not exceed 10 cm.

Upon reaching this mark under the house set of timber support and the jacks removed.

Now we need to raise the second wall.The sequence of actions of the other side of the house is the same.When lifting is necessary to strictly control the vertical position of the house.

If at some point there was a distortion of the building, it is necessary to stop the lift and move the jack in the lowest place.In this case, it is necessary to establish not vertically but obliquely.

Perform lifting should be neat, for a short distance.When the house is leveled, it is necessary to enclose a reliable support.

before continuing rise to a predetermined height, it is necessary to examine the soil around and find out the reasons why a skew.

lifting technology Long-term practice shows that it is possible to raise the wooden house, using a jack.In this situation, you need to begin to rise from the lowest angle.

Once this angle is aligned, the procedure for preparation and recovery at home in general need to perform in the same manner in which the two jacks are used.

explicit disadvantage of this method lies in the fact that the work will have more and longer.

Asked how many jacks should be performed rise buildings, the answer is simple - it is more convenient to do it with two jacks.One corner of the lift at a time can be an average of 5 cm.

Fixing house in an elevated position

Practice shows that it is important not only correctly pick up the house to the desired height, and firmly secure it in this position.This can be done in different ways.

to the house was in a stable condition at the corners puts a strong board, or so-called bench.

In appearance, this device is similar to an ordinary bench, the bench is only collected from a bar.It is set perpendicular to the wall.

fixation method is selected depending on the work to be carried out on the foundation.The video shows the house in an elevated position.

Subtleties

Wooden house process can be operated without major repairs for several decades.

weakest link in this structure are the lower crowns, which are in direct contact with the ground.Even with the high-quality processing of antiseptic wood rot.

This house can be repaired and it will stand for another fifty years.It is for this and have to raise it with the jacks.

In those places where there will be installed jacks, it is necessary to check the quality of the wood.This can be done with an awl common.Rotten timber pierced with little effort.

We must prepare for the lifting of the walls and the inside.If the house is worth the oven, it is necessary to weaken the joint of the pipe with a roof and do it right.
