Reinforcement clamp sprocket 25 protective layer 25 mm Sanpol
The 25 mm sprocket lock creates a protective layer and is suitable for reinforcement with a diameter of 6 to 16 mm, which is used when pouring walls, columns and other solutions where vertical bundles of reinforcement are needed. The asterisk protective layer retainer is used for reinforcing vertical monolithic products, when erecting walls, when pouring walls, columns, pillars, in angular horizontal frames, when working with other types of concrete reinforcement and other solutions where vertical reinforcement bundles are needed. It has a durable elastic lock that allows you to use a lock with fittings of various diameters.

The 25 mm sprocket retainer is used for reinforcing vertical concrete structures - columns, pillars, walls and protects the reinforcement from displacement and touching the formwork. Such a retainer allows you to set the desired distance from the walls of the formwork to the reinforcement frame. Most often it is used in the construction of walls, but with the help of the "asterisk" lock, other vertical structures can be erected. It has a durable elastic lock that allows you to use a lock with fittings of various diameters. The sprocket flexator can be used only for one thickness of the protective layer. The sprocket retainer is the most common type of retainers.The retainer is suitable for fittings with a diameter from 6 to 16 mm.

How to choose the correct height of the latch?
Retainers for reinforcement – allow you to achieve maximum strength and reliability of the supporting frame, contribute to pouring the exact thickness of the protective concrete layer between the formwork panels and the reinforcement mesh. The clamps allow you to place the reinforcement at the right distance from the base and the walls of the formwork. The height of the clamps is selected based on 1/3 of the height of the protective layer.
What is concrete cover?
The protective layer of concrete is the distance from the outer face of the reinforced concrete element to the nearest reinforcing bar. The thickness of the protective layer of concrete should be selected, taking into account the purpose of reinforcement in structures. The working or constructive role of the reinforcement is taken into account; the type of structure (for example, a column, slab, beam, foundation element or wall); the diameter and type of reinforcement. This is due to the fact that too thin a layer will not fully perform its functions, and too thick a layer will negatively affect the reinforced frame and lead to increased costs.
Какой толщины должен быть защитный слой?
The parameters of the protective layer are clearly regulated by the norms:
- at standard or low humidity in the room, the thickness of the protective layer of concrete should not be less than 20 mm.
- in case of high humidity inside the structures, the concrete thickness should be at least 25 mm.
- during the construction of buildings, the reinforced concrete parts of which go out into the open atmosphere, the protective layer of concrete should be 30 – 40 mm.
- for floors up to 250 mm thick, the concrete layer should be at least 12 mm. This value varies depending on the diameter of the valve. For overlaps of greater thickness, the thickness of the formation increases by 5 mm;
- the part of the structure placed in the ground without the use of additional protection should be covered with a layer of concrete from 40 to 76 mm.
- for foundations, a layer thickness of at least 40 mm is provided.
How to correctly calculate the consumption of vertical clamps per 1 m²?
For the construction of vertical monoliths, "asterisk" fixators are used. The rebar lock "Asterisk" allows you to set the desired distance from the walls of the formwork to the rebar frame. Fixators are staggered at a distance of 40-50 cm from each other.
