Rebar Spacers and Supports

Rebar spacers and supports are inset products made of polymeric materials that are designed to provide the required thickness of the safety concrete cover mounted between fiberglass building rebar and the constructional form.

Rebar spacer is a device that secures the rebar in reinforced concrete structures as the rebar is assembled in place prior to the final concrete pour to ensure the required thickness of the concrete cover. The concrete cover in composite concrete constructions is provided by placing fiberglass rebar at a small distance from the surface.

Concrete cover to reinforcement is required for well coordinated work of reinforcing bars in concrete constructions on all the stages, i.e. production, assembling and maintenance stages. Concrete protects the surface of reinforcing bars from environmental loads, such as high temperature, corrosive environment and many other factors. For planning the depth of concrete over the reinforcement the following parameters are taken into consideration: size and type of construction, diameter and designation of reinforcing bars, class and kind of concrete, application environment, etc.

Nowadays more and more often they use rebar spacers and supports for fiberglass rebar made of plastic materials and polyethylene plastics. These devices are known as plastic rebar spacers and supports. In the first place, the fact accounts for ultra-high quality of these products, and by the optimum combination of their features and cost. Due to this, inset rebar spacers and supports have an incredibly broad scope of applications. Rebar spacers and supports of the concrete cover can be used both in production process when items and constructions of composite concrete are manufactured, and for modern solid-cast buildings.

While manufacturing composite concrete constructions, it is necessary to rigidly observe the production technology and to provide one-to-one correspondence with set-up parameters. Modern construction companies, as well as plants manufacturing concrete products, also use plastic rebar spacers and supports in their work to form the concrete cover. Rebar spacers and supports are divided according to intended purposes and forms of construction. Today the most popular are the devices known as “chairs” and “stars”; several other types of rebar spacers and supports are also used in modern building and construction. So, rebar spacers and supports present a ubiquitously used construction material, which is applied in concrete constructions by practically all building companies.

Kinds of rebar spacers and supports

Rebar Spacer "Star"

Rebar spacer “Star” is the most common device for creating necessary concrete cover between reinforcing bars and the edge of concrete in vertical solid-cast type constructions. Due to application of a new system of locks, the rebar spacer “Star” excellently holds its position on reinforcing bars. Rebar spacer “Star” does not “creep” in hot weather, and herewith it is sufficiently flexible under low temperatures. The given type of rebar spacers is mounted before grouting when constructing pillars, walls and collar beams. The figure in the code of the rebar spacer shows the depth of concrete to reinforcement in mm. It is applied with reinforcing bars with diameters from 4 mm to 20 mm and secures the concrete cover with depth from 15 mm to 60 mm.

Rebar Spacer “Chair”

Rebar spacer “Chair” is designed to make concrete covers in horizontal solid-cast type constructions, and also to make filler concrete floor on the solid base. The given type of rebar spacers is very popular due to its low use rate, ease of use and low price. Rebar spacer “Chair” is mounted under reinforcing bars to provide the desired depth of concrete cover. The figure in the code of the rebar spacer shows the depth of concrete to reinforcement in mm. It is good for any temperatures, and it is applied with reinforcing bars with diameters from 4 mm to 14 mm to secure the concrete cover with depth from 20 mm to 40 mm.

Rebar Support “Cube”

It presents a unified ceiling support, which unites simultaneously four concrete covers in one product. Minimum depth of the concrete cover is 35 mm, and maximum is 60 mm. For convenience's sake there are designed two types of rebar supports “Cube”: “Small Cube” with the following depths of concrete cover — 35, 40, 45 mm and “Big Cube” with the concrete cover of 50 mm deep. It is applied with reinforcing bars with diameters from 4 mm to 32 mm under any temperatures. Owing to its stability and simplicity of operation the given type of a rebar support is commonly used in many regions of the country.

Rebar Support “Stand FSU” (tower-like universal rebar support)

The given rebar support is designed to construct floor structures and secure concrete covers in horizontal faces.

The major advantage of the rebar support “Stand FSU” is that it excellently fixes the concrete cover. It is applied with reinforcing bars of diameters up to 18mm. The depth of concrete over the reinforcement is 15, 25 mm.

Rebar Support “Wheel”

It is used to make concrete covers in vertical planes. It has five ribbed stiffeners. It is applied with reinforcing bars with diameter of 5 mm (supports 5/30). It secures the depth of concrete to reinforcement of 30 mm.

Tower-like Rebar Support “Stand FS for Loose Ground”

It is used to make concrete covers on a loose ground. It substitutes two rebar spacers and supports – a chair and a holder, besides, the resulting construction is cheaper and stronger. It secures the depth of concrete to reinforcement of 30 mm and 40 mm.
