Product ID: 4520

Glass Spike Anchor (GSA™) is a new and practical material for strengthening, repairing, and improving structures. GSA™ boasts a significant increase in compressive strength and adhesion compared to surface composite fibers such as FRP. these are due to the use of unidirectional glass fibers in the spike glass, which improves the efficiency of the composite system and prevents separation between fibers and the structure’s surface, a process known as debonding. This innovation represents a breakthrough in the field of structural strengthening.
In addition to providing appropriate shear and tensile strength in structures that require reinforcement, GSA™ also enhances performance and load capacity in cases where the structure’s usage changes. Overall, Glass Spike Anchor is an excellent option for those looking for an effective and reliable material for strengthening and improving structures.

PRODUCT DESCRIPTION Glass Spike Anchor

GSA™ spike anchors are factory-manufactured products composed of loose bundles of fiberglass. These anchors are designed to enhance the performance of FRP (Fiber Reinforced Polymer) materials by improving axial elongation and strengthening the interface between the surface and the composite fiber. As a result, the overall efficiency of the FRP composite fiber is significantly increased.

By incorporating GSA™ into FRP modification, the composite system experiences improved axial elongation properties and increased strength. This enhancement is crucial for ensuring the durability and reliability of structures. The GSA™ spike anchors effectively optimize the bonding between the surface and the FRP composite fiber, reducing the risk of debonding or separation.

The use of GSA™ spike anchors offers numerous advantages, including improved load-carrying capacity, enhanced structural integrity, and extended service life. These anchors are particularly beneficial for structures that require additional strength, such as buildings, bridges, and other infrastructure projects.

GSA™ spike anchors are available in various diameters and lengths, which can be customized to suit the specific needs of different structural projects. The manufacturing process involves bundling the unidirectional glass fibers and impregnating them with epoxy resin, resulting in a high-strength and durable material.

The use of GSA™ in conjunction with FRP provides a solution for strengthening structures that require high axial elongation and strength at the interface between the surface and the composite fiber. This innovative material improves the composite system’s efficiency, enhancing the structure’s overall strength and durability.

In addition to their excellent mechanical properties, GSA™ spike anchors are easy to install, making them a cost-effective solution for many projects. They require minimal surface preparation and can be easily bonded to various surfaces, including concrete, steel, and masonry. Overall, GSA™ spike anchors are a reliable and efficient material for improving various structures’ performance and load capacity.

Application Instructions Glass Spike Anchor

Necessary arrangements for installing glass anchors and spikes:

Preparation of the substrate (preparation of the substrate can have a significant effect 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 SPIKE glass: The design and calculations related to the use of Spike glass products 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 product execution is finished.

Guide to Quality Control (QC) Glass Spike Anchor

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

Glass anchor or spike is one of the new and practical materials in strengthening, repairing and improving structures. This product results in a significant increase in compressive strength and higher adhesion of the composite fiber (FRP) surface.

The most important difference between anchor and spike is the materials used in its construction. Glass fibers are used in one of them and carbon fibers are used in the other. Therefore, the technical specifications of glass and carbon anchors and spikes are different from each other. In addition, glass anchors and spikes have a lower price than carbon anchors and spikes due to their weaker technical specifications.

Glass anchors and spikes are used to create a suitable seal or to improve the connection of the surface and FRP composites. In fact, it can delay or eliminate premature failure of FRP joints before reaching ultimate strength. In addition, it can improve power transmission.

Glass anchors and spikes can be applied using adhesives or epoxy resins.

The advantages of glass anchors and spikes include high tensile strength and modulus, chemical resistance, etc. High mechanical, curing in ambient temperature conditions, resistant to electricity, non-corrosive, etc.

To install the glass anchor and spike, first a hole with a diameter of 12 mm must be created on the surface of the desired element. Then the surface and cavity should be cleaned from any contamination, grease, paint, dust, etc. using a vacuum cleaner, sandblaster, pressure washer, etc. The desired adhesive must be mixed according to the product data sheet. The glass anchor and spike should be manually coated with glue or resin and then placed in the created hole. Fill the hole using the desired adhesive. Then the strands of glass fibers that are in the anchor head and the glass spike must be connected to the surface. Finally, it should be allowed to cook or treat the ingredients well.

The price of glass anchor and spike is determined based on the length unit. Due to the fluctuations, it is not possible to provide a single price. For this purpose, you can contact our experts in Afzir for detailed information on the price of glass anchors and spikes.

In general, glass anchors and spikes are made up of loose strands of glass fibers together. In fact, in terms of its appearance, it can be compared to a rope with one or two ends twisted. Anchor and spike are white glass.

Glass anchors and spikes can be obtained from suppliers of reinforcement materials or manufacturers of FRP composites. One of the active companies in this field is Afzir Retrofit Company, which provides services in the field of design, consulting, supply of retrofit products, etc.
