How to knit fiberglass reinforcement at home with your own hands: Instructions + Video

How to knit fiberglass reinforcement at home with your own hands: Instructions + Video In the modern market of goods and services, it is very difficult to keep track of all the new products, for example, fiberglass reinforcement appeared relatively recently, which managed to to prove itself from the positive side.

Concrete is a durable material for pouring foundations and other purposes, but to enhance its properties, a screed is needed, for these purposes, reinforcement made of fiberglass is perfect.

In this article, you will learn how to knit fiberglass reinforcement with your own hands.

Specifications

Fiberglass reinforcement is a mixture of strong fiberglass and heat-resistant resin, stretched into bundles.

In 2012, GOST was approved, clearly regulating the requirements for the product:

  • How to knit fiberglass reinforcement at home with your own hands: Instructions + Video Diameter - from 4 mm to 32 mm;
  • 800 MPa.

    (MP - the maximum tensile strength of the reinforcement - the indicator of the force of its cross-sectional area when the material is stretched);

  • 300 MP - the maximum possible indicator of the compressive strength;
  • . 150 MPa - maximum strength;

Pros and cons of fiberglass reinforcement

Fiberglass reinforcement in a short period of time managed to prove itself as a worthy bonding material that is not inferior metal alternative, and even has a number of advantages over it.

  1. Fiberglass reinforcement is not afraid of corrosion.
  2. Lightweight. Metal reinforcement is about 10 times heavier than fiberglass.

  3. Low thermal conductivity - protection of walls and foundations from freezing, which is especially important in the northern latitudes of our country.
  4. The price is an advantage of this type of fittings.
  5. Does not lose its tensile strength. This indicator is 3 times higher than that of metal.
  6. Not electrified (current non-conduction).

  7. Monolithic. Metal fittings on drills have long cuts, and subsequently seams, which do not affect the strength in the best way.
  8. Convenience in transportation. Light enough, sold in "twisted" format, will not cause trouble even if you transport it in a medium-sized passenger car.
  9. No cracks in the foundations and walls due to the fact that GRP and concrete have the same coefficient of expansion when exposed to heat.

  10. Possibility of purchasing the required quantity. Metal fittings are sold of the same length -12 meters, there is a high probability of buying too much, fiberglass fittings are sold per meter.

TIP! First, you will need to calculate how much reinforcement you need and take with a small margin

Let's not ignore the shortcomings of this material, he also has them:

  • High probability of breakage. For metal reinforcement, this indicator is much higher; more effort is needed to break it.
  • Less safe than metal.

    In the event of a breakdown, there is a high probability of the formation of sharp edges and "burrs", which can injure yourself and leave a splinter.

We knit the fiberglass reinforcement ourselves.

Before starting work, it is necessary to decide and clear what loads will be performed by the strip foundation and the planned scope of work.

The easiest way to knit fiberglass reinforcement with your own hands can be considered knitting with the use of polyethylene clamps. The rods are fastened to each other at a right angle (90 degrees) by means of plastic clamps, the tails of which are cut off later for convenience.

This method is perfect if the mesh is knitted on the foundation of a small structure. There is no need to buy special equipment and materials for knitting.

In order to tie fiberglass reinforcement for more serious buildings, you will need a metal wire (section 1 mm), a crochet hook and the reinforcement itself.

Getting started:

  • Step 1. The bars that will be laid across must be fixed to the clips installed before.

  • Step 2. The cut longitudinal rods are placed at the same distance from each other, thought out in advance, the bonding points are marked.
  • Step 3. Jumpers are attached perpendicular to the longitudinal bars, in accordance with the marks. (step 2)
  • Step 4.

    We fold the wire in two and tie it tightly with a hook. (If clamps are used, then you must tighten them tightly)

  • Step 5. After the first layer of mesh is finished, proceed to the manufacture of the rest of the structure. Parts are attached to each other at right angles from the inside of the cells.

IMPORTANT! When knitting, special attention must be paid when knitting corners.

In specialized hardware stores, you can purchase elements for connecting structures to each other, which can be easily installed in place of corners.

Results

Knitting of fiberglass reinforcement is not a complicated process that can be carried out independently, the main thing is to follow all the technology and then even a beginner in this business will not have any difficulties.
