Reinforcement-slab foundation. Why fiberglass reinforcement?

After installation of permanent shuttering boards on the foundation perimeter, the next step was to work its reinforcement. Reinforcement FRP reinforcement was carried out:

- Reinforcement steklokompozitnaya dia. 8mm: 1600m - 22400 rubles.

- Reinforcement steklokompozitnaya dia. 10mm: 300m - 5700 rubles.

- Wire knitting, 1,2mm, 5kg: 2 pcs. - 796 rubles.

- Mason's net, 0,38h2m, d = 3 mm: 12p. - 756 rubles.

- retainer for fitting, l = 40-45mm, 250 pcs / mesh bag.: 2 -. 2310 rubles.

Some will ask whether you can use steklokompozitnuyu rebar in the foundation, in this important subject. It is possible, but not everywhere. The characteristics steklokompozitnaya fixture outperforms steel in characteristics. But it loses (and very strong) in a characteristic - in the modulus of elasticity. It does not apply where there is a deformation of the shear. Namely, beams and slabs - those are not the elements that can be used steklokompozitnuyu fittings. I think that it just can not be applied in strip foundations and stilts.

Slab foundation - it's not the beam. All plate body is lying on a bed, and there is no strain on the cut. Besides, I learned opinion fittings producer, information from other experts and looked examples of already built houses in the slab foundation with reinforcement steklokompozitnoy reinforcement. In particular, the description of the works entries from Victor Borisov in livejournal. Recommend it to a magazine - all exhaustively described, each stage of construction.

Dwell on the comparison steel and steklokompozitnoy valves will not. Information on the subject abound. The choice I made.

The entire volume of reinforcement (1900m) brought in his car at a time. Another plus - it saves on shipping. Acquired in the workplace.

Valves, 10mm, I planned to put under the load-bearing walls - on the perimeter of the foundation and in the middle.

Before the reinforcement, brought waste timber (scraps board) on the trailer brother. They were needed for mounting struts for permanent shuttering. After the dismantling of all panels, boards, bars were drank a chainsaw and went for firewood for the bath. Costs - just the cost of a trip to the base, where they gave free waste. Unfortunately, such a place is not much.

Before installing the panels, and the supports for the formwork, acquired a polyethylene film:

- Plastic film 3m wide, 100um, 10m - 385rub.

- Plastic film 3m wide, 100um, 30m - 1155rub.

Part went to something that would close the permanent shuttering from falling concrete - not to soil the decorative surface by pouring the foundation. And the bulk of the film - that would cover the plate at the time of curing (to prevent loss of moisture concrete).

Next, he began to cut rebar segments to the desired length. For this measured two lengths: the length and width of the foundation by mounting three pegs. The two pegs hammered and bent nails, which were fixed, clamped ends of the valve. And about the third - cut fixture grinder. But first steklokompozitnuyu fittings needed to unwind. As it is fast and safe to do, given in the article on video here

Cut into segments of the desired length - dragged them into the basement area.

With this reinforcement must be sure to work in a rubberized gloves. Fiberglass is very delicate, bites into the skin and then begin your hands to itch.

Showing shields, holding up the permanent shuttering and part laid and related fittings.

Yes, that's gained even a crochet hook for mating fittings:

Many people do not knit fittings and fasten it with plastic bundles. It's a bit faster, but more expensive.

Knitted reinforcing mesh with a cell 200h200mm. To do this, cut from thick MDF (it is possible from any board) - the square, tied to his hand. Stack armature faces to this template, and a hook tied tie wire segments, napilennye of grinder bay.

Learning how to knit - a lot of the Internet and video in youtube.

The work is very tedious. Tired of the back and knees. In the process of tying thousands of knots of wire was connected.

After the first ply cords - fit over the second. There is no longer need a stencil. Reference is on the grid of the lower layer. After finished knitting all layers - planted under the first armature layer retainers. They are necessary in order that the valve was in the concrete body, and not at the surface. In my case - it is at a distance of 45 mm from the edge.

Two layers of reinforcement are connected and are raised to a height of clamps. Now it was necessary to raise the top layer of reinforcement on 200mm above the bottom. When the total thickness of the plate of 300 mm - and the upper reinforcement layer is a body of concrete 5 cm below the upper edge.

For this I cut grinder of masonry grid segments bent at 90 degrees and tied to the upper part of the top layer of reinforcement binding wire. They relied on the ground.

Not all completed the. It was a few stands of metal masonry grid.

These works took 17 days. Almost all the time - knitting accessories.

The next step - is pouring the foundation.
