The ribbon foundation is particularly popular in the construction of private houses. To build a ribbon foundation for the house, you need to study some features of its construction: make the right calculation, perform reinforcement and prepare concrete for fill. This foundation is used where it is necessary to make a basement or underground. If at the selected plot for construction, the soil freezes enough deeply, then the ribbon foundation for the house will be very expensive.
At the very beginning, it is necessary to determine the composition of the soil, only after that it will be known which type of ribbon foundation It is worth choosing which depth of it to use, how many concrete and reinforcement will need.
You must have a diagram of a project of the house under which the foundation should be made. Use it when erecting the foundation. Make the breakdown of the axes for the fill of the ribbon foundation using the theodolite. If you do not have this device, you can use pegs and rope. Next you need to dig a trench with your own hands or using special equipment
Trench fill with sand, thoroughly confuse it, then fall asleep gravel or crushed stone. The total thickness should be about 20 cm. After rubble, fill with concrete, the thickness should turn out to be 10 cm. Concrete will type the necessary strength in 5-6 days.
Next is laying fittings. It is necessary to reinforce the transverse and longitudinal rods, the reinforcement is associated with wire. Armature must be coated with an anti-corrosion coating. Sometimes they make a more complex frame.
The next stage is a formwork device for a ribbon foundation. To do this, use boards, fane, slate.
And the last stage is directly filling with concrete. The brand of concrete is determined on the basis of future loads on the foundation. Typically take the brand of concrete M200 and above. The correct ratio of sand-crushed cement for concrete - 3-5-1. The calculation of the amount of concrete is the multiplication of the length to the height and width of the ribbon foundation.
When a concrete mixture is filled into a formwork, it is poured in several places with a dipstick. This is done in order to remove the air from the ribbon foundation, so it becomes stronger and more reliable. Outside, the concrete mixture is sprinkled with wooden or rubber hammer.
After pouring the concrete, formwork needs to be removed. This is usually done in 2 - 3 days. Only after the concrete gains sufficient strength, make a concrete base.
All these procedures can be made with their own hands, without the help of specialists. I have been playing at
