Reinforcement retainer sprocket protective layer 40 mm, 250 pcs. Sanpol
The 40 mm sprocket retainer 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.

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?
Параметри захисного прошарку чітко регламентовані нормами:
- при стандартній або зниженій вологості в приміщенні товщина захисного шару бетону не повинна бути меншою за 20 мм
- при підвищеній вологості всередині споруд товщина бетону має бути не менше 25 мм
- при будівництві будівель, залізобетонні частини яких виходять у відкриту атмосферу, захисний шар бетон повинен становити 30 - 40 мм
- для перекриттів завтовшки до 250 мм шар бетону повинен становити не менше ніж 12 мм Ця величина варіюється в залежності від діаметра арматури. Для перекриттів більшої товщини товщина шару зростає на 5 мм;
- частина конструкції, розміщена у ґрунті без застосування додаткового захисту, має бути покрита шаром бетону від 40 до 76 мм
- для фундаментів передбачена товщина шару не менше 40 мм.
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.
