Spring clip: features, characteristics and application of the device

Today in the construction industry it is already difficult to come up with something new. This applies to all stages of construction, including the manufacture of formwork. Like 20-40 years ago, screws and nuts are used to tighten shields. This ensures the strength of the connection, but it has unpleasant consequences: after the formwork is removed, unsightly holes remain on the concrete product. And their presence violates not only the aesthetics of products, but also their durability. Eliminate these shortcomings can be if you use a spring clip for formwork. What kind of adaptation is this?

Features & Benefits

Clamping devices are indispensable in those objects where concrete monolithic structures are created. The larger they are, the greater the number of clamping elements, respectively, needed to keep the formwork in position. Would it be expensive and why should only use a spring clip? The advantages of this element are quite tangible and consist in the following:

1. No need to apply cones and tubes when installing PVC, which is already economical.
2. Quick installation - for fixing it takes a few seconds.
3. Low cost - the price of clamps is half that of nuts with bolts previously used for formwork.
4. Versatility - can be used when installing any formwork on any objects.
5. To use a spring clip, you need a key (included in the kit) and a reinforcement bar, which is on any construction site.

Characteristics

One of the most important properties of clamping elements is the ability to withstand colossal loads. For this, different types of clamps are produced - conventional (up to 2 tons) and reinforced (more than 2 tons). But this is not the limit, today there are produced strengthened types of clamping elements, capable of withstanding loads up to 3 tons. But, despite this high performance, the spring clip has a very simple design. The form of the device is a clip-type lock. The element has a closing tab and is placed on the platform.

For the manufacture of heavy-duty tongues, only hardened metal is used in production. The teeth are therefore very strong and can withstand any stresses. To avoid corrosion on the surface of the element, it is treated with a galvanized compound. The thickness of the platform is 0.4 cm. It is equipped with a very tight and very strong spring.

Application of devices

The installation process is as follows:

1. A reinforcing bar is used to fasten parallel shields.
2. The ends of the rod are taped into the lock.
3. The fixing element is fixed by means of a key.
4. The opposite locking joint self-snapping.

As a result of carrying out all the manipulations, a very strong formwork is obtained for monolithic construction, when removing it, there is no problem - you only need to hit the tongue with a hammer. This operation eliminates the tension of the lock, and it can be easily removed by hand.

To complete the installation process, it is necessary to cut off excess projecting parts of the reinforcement, and the rest of it remains inside the concrete structure, so that its integrity is not violated. Thus, this technology is very simple, but very effective.

What is important, you can use this type of fasteners not only for the manufacture of formwork. Spring clamps are indispensable in the construction of objects of varying complexity, where the formwork for monolithic construction must be particularly strong. It:

1. Walls.
2. Tunnel shafts.
3. Bridge structures.
4. Columns and many other constructions.

The most popular products

Today, not only Russian builders produce and use the spring clip, but also foreign ones. In the Russian market you can see products of the following brands:

1. PROM. The Turkish product is designed for loads of about 3 tons.
2. Hold. The products of the Turkish brand are designed for loads of no more than 2 tons.
3. ALDEM. The Turkish production lock can withstand loads of over 2 tons.
4. "Chiroz" (the frog). The products of the Russian manufacturer are designed for loads of about 2 tons.

But before releasing this type of product for sale, all manufacturers subject it to various tests. Only after that protocols and certificates are issued, without which products can not be realized. Thus, the spring clamp of any brand has a guaranteed high quality and is approved by highly qualified specialists, so it can be used on any construction site.
