How to raise a country house

Any of FORUMHOUSE knows the members that on careful planning of construction depends on the reliability and durability of the house. Particularly noteworthy is the construction of the foundation phase.

But sometimes it happens that the problem with the foundation or the building there are a few years after their construction.

The foundation is cracked and began to crumble, rot the lower crowns of the wooden house, too small or the height of the cap structure of mowing and "village" on one corner, its lower part is constantly moistened. To the foundation had not collapse until the end, the owner of a country house thinks about repair. But this is difficult, the building is already on its base.

In this case, you can raise the house, put it on temporary supports, carry out the required repair works and drop into place on the renovated ground.

And since prices from construction firms for such services bite, many forum users are taken for the uplift of the wooden house on their own. And if we are more or less clear how to lift the country house, is when it is not a country, but a big house out of wood for living, the difficulties begin.

Read on FORUMHOUSE, how to raise the shield house their own hands and that it is necessary to raise the panel house.

suchhund (Member FORUMHOUSE):

- I alone raised wooden frame house 6x6 m The reason that forced me to go. such a step was the destruction of the old foundation and the desire to live "higher" from the ground, away from the dampness.

Fundam forumchanin y is the width 30 and height 50 cm unreinforced tape. 20 cm tape was buried in the ground, the rest are 30 cm above the ground.

Due to the fact that the foundation was built with violation of the technology in the 70's of last century, he began actively to fall apart. I thought about how to raise the house jacks and develop a work plan for the modernization of the base, the first thing Validating acquired tools: two inexpensive jack lifting capacity of 8 and 10 tons.

Then suchhund sawed wood pads of boards and beams of different lengths. Gaskets are required to at least lifting jacks structure, enclose them under the lower crowns, until it reaches the desired height. Total forumchanin sawed 100 pads of different sizes.

Next, using a sledgehammer, suchhund struck eight mounting openings in the foundation began to crumble. In the opening set, and a jack. It received two of the opening on each side of the building.

suchhund(Member FORUMHOUSE):

- it perfectly clean concrete fight, I set the jack to lift openings and beginnings. For once I put up a house wall no higher than 20 mm, and then put the pads rearranged in another jack doorway again be phased lifting.

During lifting the house can open the window, it will protect windows from possible cracking.

Raising buildings was carried out in a clockwise direction.

In order to reduce the weight of the building, forumchanin ruled out of him all the furniture and household utensils. For two days the structure raised by 60 cm. "Jacking" the building to the required height, forumchanin engaged in a new reinforcement strip foundation being built on top of old, spillage which was already evident to the naked eye.

suchhund(Member FORUMHOUSE):

- The case went all that remains of the old stock from the construction site. The working valve 12 I selected A-III, on collars took armature 6 A-I. The cross section of the new tape, poured over the old one, was 30x50 cm.

To link the two together foundation, forumchanin spudded in the old tape anchors 6 mm below the clamps. The entire perimeter of the foundation he tied immediately, except for those openings where there were temporary supports, which were inside the reinforcement cage. To a foundation after pouring concrete remained produhi, suchhund took plastic pipe of 150 mm diameter and sawed into 12 pieces of its length 30 cm. On each side of the building came to 3 ventilating air holes. In total, the foundation reinforcement process took 2 days.

Read our article on howwhether the air holes are needed in the basement.

Then came the turn of the formwork installation.

suchhund(Member FORUMHOUSE):

- Boards for formwork I hit the sheets of hardboard, napilennyh size 2x6 meters. For rigidity fastened to the shields 3 boards "twenty" 2 meters long and three boards "sorokovke" 6 m long. The inner surface of shields I closed the film, and for extra strength pulled the boards with steel pins, passed through the plastic tube diameter 22 mm.

As a result, after the installation of the formwork, the bottom of which was based on the old foundation, uncovered were only the mounting openings. Repulsed horizontal leveling instrument, forumchanin proceeded to pouring a new foundation. Mixture - "samomes» suchhund prepared with such proportions of materials:

• 1 M500 portion of cement;
• 1 part of pure water;
• 3 parts of washed river sand;
• 2 parts of crushed granite fractions 5-20.

suchhund(Member FORUMHOUSE):

- Concrete mixer I interfered. After pouring the foundation provibriroval mixture vibrators. If you do not, then you can forget about the qualitative foundation. After the concrete has gained strength, the top tape I covered waterproofing and dropped a house on a new foundation.

Instructionsfrom our experts

Although suchhund carried out repair work on the foundation of a very high quality, the experts of our site and to read with this example, They came to the rescue and gave a few tips to guide users FORUMHOUSE, who decided to do their own "rigging" works.

Igor Bekker(Member FORUMHOUSE):

- I've been lifting and shifting of homes since 1984. It should be noted that the above method of setting temporary wooden linings is very dangerous, and here's why. Gaskets must ensure reliable stability of the whole structure, otherwise the structure could tip over. Lower gasket is best done of concrete blocks, and for putting up the house to use special welded goats (tables). And pour a new tape is better than individual blocks, and the whole - a monolith.

Gromozeka(Member FORUMHOUSE):

- Imagine instead of concrete cubes (blocks) - steel support in the form of parallelepipeds of the welded corner, colon or sill reinforcement. In these blocks to be skipped fixtures, link it through, then put the formwork and pour concrete. That will have a single piece construction of strip foundation.

Welded cabinets, props, zamonolichivaemye in the tape, do not interfere with pouring of the foundation, and the reinforcement and formwork rests on them.

It is important to remember that any error made during the work on the structure of the rise, can lead to the fact that it can bend, move out of temporary supports and falling. Among these errors stand out:

• Fast, irregular and too high a rise of one side of the house;
• Insufficient strength of the temporary supports. But at the building as it stands "on chicken legs", more action and wind loads;
• Insufficient strength to which abut jacks;
• Wrong calculation of the lifting force of the jack, you need to detach from the base of the house.

Therefore, the structure of the rise is necessary to begin with a number of nuances proschityvaniya directly affecting both the safety of designs (windows, doors, roof system, etc.), as well as the safety of working at home "Scaffold."

Igor3(Member FORUMHOUSE):

- Frequently asked question: how to raise the wooden house on jacks so as not crumbled. Tip one - you need to understand where the vector is directed forces applied. Raising the structure can be both clockwise and vice versa. We do 3-10 laps (as long as necessary) until the house does not rise to a sufficient height. I do not advise him to raise more than 350 mm, although we raise the house up to 80 cm, and with the use of a special technology - up to 1.8 meters. When lifting to avoid rocking the building. It comes with experience - already feel the time after which it will begin to lose stability.

Practice shows that the lift frame house up to 7 tons of missing 1 jack with a force of 10 tons. The house will have to lift slowly, gradually moving the jack on the different points. Lift building (one side of it) can be no more than 3-5 cm at a time, working in a circle! When professional works simultaneously used by 15-20 jacks.

Under the wooden beams of the building to enclose the metal plates. To increase the contact area convenient jack rests on the wooden lining, which increases the footprint on the ground.

Horizontal lift monitored visually at the point of separation, template (scraps boards) because laser level is difficult to see during the day.

You can raise and stone buildings, but also use other technology, the details of which will be devoted to one of our next articles. Stone structure must be raised all at once, simultaneously from all sides, otherwise the lift will lead to the destruction of the building.

Igor3(Member FORUMHOUSE):

- Lift can be any home. It is difficult to raise the structure of brick. The cost of such work often exceeds the cost of the building itself. Therefore, if the brick building of no historical or architectural value, raise or move it impractical.

Turn-based technology built in stone lifting following - in the basement openings are cut by a powerful beam. Beams are welded into an integral frame. To lift the stone house will take a few tens of jacks that are connected to each other hoses or computer-controlled. Jacks are used by 50 tons.

Such techniques are more costly, because require more equipment, tools and skilled workers.

almost pros(Member FORUMHOUSE):

- To lift the stone buildings professionals use very expensive hydraulic station with a hydraulic cylinder. Needs metal, I-beams, welding, many fasteners, as Basement becoming the basis of a double metal frame. Therefore, the price tag on a corresponding work.
