Increased Corrosis for formwork
In modern monolithic construction, the speed of installation, accuracy and reliability of the formwork are of crucial importance. One of the most important elements that ensures the stability of the structure during concreting is the reinforced formwork (spring clamp, frog clip, formwork lock). This compact but powerful element allows you to quickly and safely fix the formwork panels without the use of tie rods and nuts.
What is enhanced chirosis?
Reinforced chiroz is a special reusable spring clamp made of hardened high-strength steel . Its design includes a disk mechanism with teeth that firmly fix reinforcement with a diameter of 6 to 10 mm . Due to the improved metal thickness ( 4 mm ) and the increased plate area ( 110×75 mm ), the reinforced chiroz can withstand loads of up to 3 tons , ensuring maximum rigidity of the formwork system.
What are reinforced chiros used for?
Reinforced formwork ties are used to secure formwork panels when concreting foundations, columns, walls, beams and floors. They are especially effective where it is necessary to withstand high pressure from fresh concrete and prevent formwork panels from skewing.
These clamps are also ideal for:
-
pouring monolithic belts and stairs ; -
fastening of formwork without tubes and cones ;
-
work in difficult conditions where installation speed is important.
How to install a reinforced chiroz?
Installation is simple and does not require special skills:
-
The reinforcement is passed through the holes in the formwork panels, leaving a protrusion of about 15 cm.
-
A screw is put on the reinforcement and tightened with a special key for screws .
-
After dismantling the formwork, the ends of the reinforcement are simply cut off.
Thanks to the well-thought-out shape of the clamp, installation and removal are several times faster than when using traditional pins.
What are the benefits of reinforced chiroza?
High strength - withstands loads of up to 3 tons. 
Thick steel (4 mm) guarantees durability and resistance to deformation.
Quick installation - no complicated tools required.
Reusable - saves on consumables.
Compatibility with 6–10 mm reinforcement - a universal solution for various objects.
Protection against skewing - thanks to the spring mechanism, fixation is as precise as possible.
How to distinguish enhanced chirosis from ordinary?
| Parameter | Ordinary chiroz | Reinforced chiroz |
|---|---|---|
| Steel thickness | 3 mm | 4 mm |
| Plate size | 105×72 mm | 110×75 mm |
| Coating | painted | galvanized |
| Strength | up to 2 tons | up to 3 tons |
| Durability | average | high |
The reinforced wire has a galvanized surface that prevents corrosion, especially when working in wet conditions or with repeated use.
Do I need a special key for the chiros ?
Yes, a key for the formwork ensures uniform and reliable tightening of the clamp. This guarantees correct fixation and prevents the formwork from shifting under the pressure of the concrete. Using the key also extends the service life of the formwork itself.
Where to buy high-quality reinforced chiros?
The most reliable are considered to be Turkish-made dowels . They are made of high-hardness steel, undergo heat treatment and have quality certificates. By purchasing from a trusted supplier, you get guaranteed fixation accuracy, durability and safe concreting .
Reinforced crossbar is a small but extremely important detail that determines the stability and accuracy of the entire formwork system. Its use significantly reduces installation time, improves the quality of concreting and saves money. For professional construction, it is an indispensable solution that ensures speed, reliability and safety .
