Less than a week, as the trench is already fully prepared for laying reinforcing cage and pouring the concrete foundation.
of foundations
As mentioned in the last article of the trench device is a strip foundation was chosen for my home, as the basis from the calculation of existing species - he left some cheaper than others, and for preparatory work - did not require a lot of efforts.
According to the results of calculations for bearing a base of the building to the ground, the width of the foundation cushion constituted by the outer walls - 0.7 m, on the inner wall -. 1.0 m, a height -. 0.3 m.
Reinforcement
According to the design specifications was purchased fittings, but I had to save on the diameter, since the project was supposed to use 14th bars, and I purchased 12 mm., As designers in the calculation always are reinsured and lay down by 20%, or even 30% higher stock.
Inside the excavated trench knit frame it is not very convenient, since its width is about 45 cm., So I did not invent bicycle and related frameworks at the site in the immediate vicinity of the trench, erecting props of boards of wood pallets.
In knitting using a knitting 1.2 mm wire diameter, mesh size tried withstand acc -. 300 mm.
For the manufacture of one 40 meters of the reinforcement cage 1 m high. It took 3 days.
When the frames are fully assembled, the day of pouring the foundation made the descent of carcases and interconnection of the same wire. Each six-meter metal frame weighing about 120-150 kg, so that would not derail the edge of the excavated trench -. Their installation made four.
concreting
For pouring the concrete foundation using M200 trade mark with a mixture of P4 mobility delivered by truck mixers.
Instead of hiring a concrete pump, as a chute for concrete, I found an alternative - a special tube is connected to the feeding chute of the mixer.
Laid mixture was compacted submerged vibrator.
Concreting all basement (27 m. Cu.) Was about 4 hours with latency mixers between races.
At the expiration of 7 days after my foundation pouring, I removed the formwork, which is only used for to the upper part of the foundation was an aesthetically smooth, without protruding gravel, pieces of frozen mixtures, etc.
Starting from the day care needed for concrete, namely a couple of times a day (morning and evening) during the week had it moisten with water from the hose.
The amount of money spent on the entire stage works from digging trenches and finishing concreting, was as follows:
- 27 concrete cube. m with delivery -. 71 thousand rubles .;
- fittings 2600 lm - 44 000 rubles .;
- boards, binding wire and other trifles - 6000 rubles .;
- s / n workers - 20 thousand rubles.
Total 141 000 rubles.
That's the next stage of construction is passed, but there is still so many interesting...
