carbon spike anchor

Carbon anchor or spike (CSA ™ code) is one of the new and practical materials in strengthening, repairing and improving structures. FRP Spike has been one of the practical methods in the installation and use of FRP fibers, which causes a significant increase in pressure and higher adhesion of the surface and composite fiber (FRP). Carbon anchors are composed of unidirectional carbon fibers. The use of spikes and carbon increases the efficiency of the fiber (FRP). It is mostly used in strengthening, repairing and building all kinds of structures, and in addition to the desired shear and tensile strength in structures that need reinforcement, they are also used in cases where the user is changed. Among other advantages of carbonized anchors, we can point out the prevention of separation and debonding between the fibers and the surface.


PRODUCT DESCRIPTION

The CSA ™ Spike Anchor is a factory manufactured product from a loose bundle of carbon fiber. Using CSA ™ to modify FRP (Fiber Reinforced Polymer) improves axial elongation and strength of the interface between the surface and the composite fiber (FRP), improving the efficiency of the composite fiber (FRP).

Surface preparation for carbon anchor implementation

Substrate preparation can have a significant impact on the quality of system performance.

• All surfaces must be cleaned of dirt, grime, dust, oil, grease, wax and other contaminants.
• In case of unevenness or contamination, the surfaces need grinding, sandblasting, pressure washing or other usual mechanical methods.
• An industrial cleaner should be used to remove dust.
• Note that concrete surfaces must be completely dry or clean to allow the adhesive to dry.

How to use Carbon SPIKE:

The design and calculations related to the Spike method and the FRPs used are carried out according to the regulations and standard specifications by design engineers. We mark the desired place for anchors with a circle and make holes with a diameter of 12 mm. To ensure that the anchors sink completely inside the holes, the depth of the holes is 3 mm larger than the height of the anchors. After that, blow on the surface of the concrete and inside the holes with the available tools, so that the dust disappears and the surface and the hole are clean. Resin or other types of adhesives compatible with this system are used to impregnate FRP sheets, concrete surface and anchors. Then connect the FRP and the execution of the method ends.

Guide to Quality Control (QC)
  • All components of the composite FRP system may cause skin irritation and sensitivity, so the use of chemical resistant gloves is recommended.
  • Avoid breathing vapors and dust and consult a doctor if breathing is difficult.
  • Resin products can cause severe eye irritation. Avoid contact with eyes and use safety glasses.
  • This method should not be performed in cold and humid weather.

Frequently Asked Questions

What is carbon anchor and spike?

Carbon anchors and spikes are groups of unidirectional carbon fibers with the same length, which are used to provide restraint and connection between FRP composites and the desired element.

How to implement carbon anchor and spike?

First, the desired surface must be cleaned of any contamination. Then create a hole in the desired surface with a diameter of 12 mm and remove any dust and dirt from inside the holes using air pumps. Then the corresponding resin should be mixed according to the manufacturer's instructions. The anchor and spike are placed inside the cavity and coated with the prepared resin manually. In addition, the cavity should be filled with resin. Finally, the setting time must be passed.

What is the use of carbon anchor and spike?

Carbon anchor and spike strengthen the connection between the FRP composite and the surface of the desired element by creating a suitable anchor. Anchor and spike improve the performance of FRP composites. In addition, it prevents FRP composites from separating and delaminating from the surface. Anchors and spikes are usually used in the side areas where it is not possible to create a connection between FRP reinforcement sheets and the surface normally.

What is the price of carbon anchor and spike?

The price of carbon anchor and spike is determined based on the required length. Due to market fluctuations, it is not possible to provide a single price. For this purpose, you can contact our experts at Afzir retrofitting company to inquire about the daily price of carbon anchor and spike.

What is the shape of carbon anchor and spike?

Carbon anchor and spike can be compared to a rope with two ends or one end of which is stringed.

What resins are used with carbon anchor and spike?

Carbon anchor and spike is compatible with resins such as epoxy resin and vinyl ester resin. Therefore, it can be implemented using these resins.

How to prepare carbon anchor and spike?

Concrete anchors and spikes can be obtained from companies that supply reinforcement materials, such as Afzir Reinforcement Company, which is active in the field of design, consulting, supply of reinforcement products, etc.

What is the feature of carbon anchor and spike?

Carbon anchor and spike have high chemical resistance and do not corrode. In addition, they have high tensile strength and resistance.

What are the conditions for keeping carbon anchor and spike?

Carbon anchor and spike should be kept at a temperature of 4 to 32 degrees Celsius. In addition, it should not freeze and should not be exposed to direct sunlight, flame, moisture, water or other hazards. If it is stored properly, it can be stored for up to 10 years.
