Procedure for proper reinforcement strip foundation

click fraud protection

Strip foundation is most common because of its versatility for most types of soil, and the possibility of heavy weight constructions.Its construction is quite labor-intensive, and requires mandatory reinforcement - strengthening concrete metal structures.It is intended to compensate for the effect of forces to the concrete compression and tension, preventing it from damage due to temperature fluctuations and high loads.

For reinforcement, a special rod with a smooth surface from 6 to 32 mm in diameter.its installation requirements according to the type of soil structure, the thickness of the valve described in SNIP and are required to comply with not only the largest building contractors, but also in self-construction home.

For private 1-2 storey buildings most commonly used valve section 10-12 mm (possibly composite), putting it at the top and bottom of the basement.The upper and lower layers are connected by vertical supports increments of 50-80 cm, which account for a small load.The diameter of the vertical reinforcement may be less than 6-8 mm.

horizontal bars, the distance between which should be no more than 30 cm, are laid overlapping, interlocking them with the vertical.Each layer has 2-4 rod.For melkozaglublennogo foundation only two layers for glubokozaglublennyh - three.




circuit - reinforcement

for corrosion protection valve must be completely immersed in the top concrete.From its formwork must also be separated in a layer of 6-8 cm most common method of binding reinforcing rods -. Connection via wire and crochet hook.Welding is used only for certain types of valves.

phased reinforcement technology

reinforcement can be divided into two stages.First collected frame of twigs exactly the size of trench under the foundation of the future and in accordance with the calculated load.It can be assembled in stages, using a long bench, accrued using the boards on the entire length of the rods.First harvested thinner vertical bars of the desired length and assembled with the help of the wire rack.

Then laid out on a flat surface with a thicker reinforcement, these racks are mounted binding wire approximately every 30 cm. It is ready to lower horizontal reinforcement belt.The top is similar.

angle

Particular attention should be paid to mating valve angles to the part of the foundation are rigidly connected.Portions of the reinforcing cage at the corners reinforced L-shaped elements with a side of not less than 40 cm. The vertical stand at the corners must be placed twice as often as the main part.

Once ready formwork for the foundation (how to do it, read here), you can proceed to the next phase - installation of the finished reinforcement cage and concrete pouring.Before pouring the concrete must be routed through the bars of the pipe fittings for communication and ventilation.For a more uniform distribution of the concrete must be poured layers, each of which flatten Vibroplatformy or carefully by hand.After drying is carried out in all the foundation waterproofing roofing felt or mastic asphalt, according to the technology described herein.

strength and durability of the house are directly dependent on the correct laying of the foundation and its strengthening.This important phase of construction is best to entrust the professionals who perform the labor-intensive stages of filling and reinforcing the base properly.Independently undertake this process is only if you have experience and confidence in their own abilities.
