Building houses has never been a particularly cheap pleasure, but in recent years, those who want to get their own house have to save on almost everything. In particular, many of them are interested in the fact that the knitting of reinforcement for the foundation was done by their own hands, since the work of specialists in this field does not differ in democratic prices.
How to connect fittings?
Today, two main methods of fastening are used: on wire and on welding. Each of them has both positive and negative sides. It seems to non-professionals that welding is a more reliable and high-quality type of fixture, but in practice, everything turns out to be somewhat wrong. Such knitting reinforcement for the foundation has a number of negative qualities:
- If you use welding, then construction will be more expensive, since you will have to use special equipment and the services of professional welders. Do not throw aside the fact that welding machines consume a lot of expensive electricity.
- Paradoxical as it may seem to you, but knitting reinforcement for the foundation using wire is more reliable than welding. The fact is that the places of welding are characterized by an increased tendency to corrosion and kink due to mechanical factors.
- In addition, this method unreasonably increases the rigidity of the entire reinforcing frame of the building. Simply put, the foundation will no longer be able to "play" after the moving soil, as a result of which wall cracks and other dangerous consequences are possible.
Using wire will get rid of almost all of the above risks.
Getting ready to do the work ...
To knit reinforcement for the strip foundation went “perfectly”, we recommend that you adhere to the following work plan:
- The material should be carefully prepared.
- Sling is in progress.
- Bonded structural elements are delivered directly to the place of work.
- Referring to the plan of the frame, they are installed in the foundation trench.
- Proceed directly to knitting.
The first stage involves a thorough visual inspection of the fittings. All dirt and rust from its surface must be removed with a quality iron brush. Please note that the pattern of knitting reinforcement for the foundation involves the use of only direct reinforcing rods, so that they are straightened before use.
Hand knitting
In this case, the strapping is performed in the upper, lower and middle parts of the reinforcing frame. Professionals say that it is best to do these jobs in the following order:
- The wire is held in the left hand, and the tool is held in the right hand.
- A wire is held under the armature itself, a wire loop is pulled by a crochet of a knitting device.
- Make a knot.
- Scrolling the hook three to four times to secure the wire, cut off the free end.
The most difficult thing is when the reinforcement for the foundation is knitted along smooth reinforcing bars. In this case, you should use a special automatic gun for knitting, which will not only speed up the process, but also greatly simplify it.
