To determine whether the rotted log or not, lightly tap it with butt of axe. A hollow sound will tell you that with a log, things are bad. And it is better to arm themselves with a knife and try to stab all the logs, causing you suspicion. Free penetration of the tip at a greater depth will give you a reason to think about replacing the logs.
Having dealt with the logs, prepare the site for felling and collection of crowns and pick up logs of the same dimensions, and model, air-drying and clearing them from the bark.
Then dig up at a distance of about half a meter from the corners of the houseand a few holes (two at each wall). The pits must have these dimensions: length along the log – 100cm, width – 70cm, depth logs – 50 cm the Bottom level and put on a broad or scaffold planks.
Then you will need a pair of hydraulic buildingkrath, calculated on a five-ton weight, different wood, thick trim boards and brackets.
Check and record the position of the frame, beat on the walls two horizontal straps. In places rise buildingand staple the thick logs with boards to ensure that nothing has shifted. Then in the pits install housecrats from the logs lying on the bottom logs. Under the housekratom should be a place for putting the block of wood. For greater reliability to put under the heel of the houseof kratom steel plate.
Quietly raise your house, while controlling the bias level. When coming to focus the beam out of the cups downstream of the logs, stop the lift. Jacks work in turn. If the house rises from the laborhouse, substitute a log, block of wood and lower the housecrats, and under the log, substitute the wood with spacers, after which you can resume the climb. Do not remove the wood. Let them be insurance. Lifting a houseand 30 cm, clamp it on the wood, and then proceed to the other side. Repeat the operation, then roll out the bottom log. Replace them and lower the house. This should be done gradually, first lifting the houseand then down before removing the wood.
Advice 2 : How to raise the corner of the house
Not to say that the rise of the house – the operation is simple. Better if they will deal with people who had to face this earlier – preferably professional carpenters. However, if you enlist the help of professionals for any reason you can not, you can handle this job on their own. The main thing is to be slow, calculating and careful.
You will need
- – hydraulic 10-minute or 20-ton Jack;
- – wooden beams cross-section about 150х250 mm or railroad ties;
- construction and carpentry tools (crowbar, shovel, axe, etc.);
- – thick metallic plate (lining under the head of the Jack).
Calculate the approximate load on the corner of the house (the weight of the house, divided by 4). This parameter is necessary in order to choose the size of the beams, which will draw the corner of the house after his recovery. Please note as reference the following information: installed at the edge of the railroad tie, having a section 160х230 mm, with a span length of 2.5 m can withstand a Central load is 4.5 tons.
Determine the location of the focus of Jack. It should be chosen according to the specific situation. If you raise a house to replace the rotten bottom of the new crowns, cut an opening in these crowns until the whole log, which will rest on the Jack. The opening should be cut wide enough to fit the Jack and the beams, which will build the house after lifting.
If the house is raised to increase the height of the Foundation or base, then, to bring the head of the Jack under the beam, it is necessary to hollow out a niche in the Foundation – if it is the belt. If the house is located on the pier Foundation, the need for the excavation of the niche disappears.
Place a Jack under the log. If its fifth is the soil, tamp it well and put it on a Board or thick Board. If Jack is the concrete surface of the Foundation, also put it on a thick Board that is necessary for load distribution and stability of the heel.
Under the head of the Jack put a thick steel plate with a size of about 10 × 10 cm, it is Desirable to have in the centre a small concavity or milling – in as a guarantee against slipping off of the head. Podesite the beam in the place of installation of the lining in a horizontal plane.
Set near the corner of the rail, sticking it into the ground. Mark, on the rail and on the corner of the house line, which is on the same level. The alignment of these lines during the lifting process, will report on the amount of lift. To control this Anakena the extension of the rod of the Jack is impossible, because his heel will be pressed into the Board and the ground.
Start lifting at home, working the Jack handle. At the same time, pay attention to its verticality. If there is a deviation of the instrument from the vertical, stop the lift and set the Jack again.
When working, follow these rules.The rise of the house should be carried out simultaneously by two jacks, mounted under the corner of the house. Lifting one corner only if he slipped to the three others and have to align it.
Lifting one hand in a single cycle should not exceed 4-6 cm then you need to put under the wall stops and start to lift the opposite side.
Raised face fixed in two ways – padded thick boards between the beam and the Foundation or device of the so-called "benches." In the latter case the timber is placed under the wall perpendicular to it, and its ends rest on bearings mounted on opposite sides of the wall. To choose a particular method should be based on the nature of the work produced by the house (replacement of crowns, filling of Foundation, etc.).
