Comparison Of Advantages And Disadvantages Of Using Chemical Anchor Bolts

1, The application scope of chemical anchor bolts
Chemical anchor bolts are high-strength and highly reliable anchoring materials with a wide range of applications. Not only can it be used in the installation of post embedded parts in curtain walls and marble dry hanging construction, but it is also widely used in various fields such as equipment installation, highway, bridge guardrail installation, and building reinforcement and renovation. The application range of chemical anchor bolts is very wide, with stable and reliable effects, making them popular.
The chemical anchor bolt we use is a composite component that uses a specially designed chemical adhesive to bond and fix the screw in the drilling hole of the concrete substrate, in order to achieve anchoring of the fixed component. Stainless steel A4 anchor bolts can be used in outdoor, humid spaces, industrial pollution areas, and nearshore areas; Galvanized steel and stainless steel A4 are not suitable for damp spaces containing chlorine. Moreover, chemical anchor bolts are also suitable for fixing substrates with small wheelbase and multiple anchoring points, and have the advantages of special application scenarios.

2, Can chemical anchor bolts be used for curtain wall embedded parts?
The production and installation of curtain wall embedded parts require the use of some auxiliary fixing materials, and chemical anchor bolts are one of the very common materials used for fixing curtain wall embedded parts. Although chemical anchor bolts are commonly used for fixing curtain wall embedded parts, chemical anchor bolts also have their shortcomings, mainly manifested in the inability of their chemical agents to withstand high temperatures. Welding high temperatures on the embedded parts after chemical anchor bolts will directly affect their load-bearing capacity.
Strictly speaking, the Shanghai Curtain Wall Code DGJ08-56-2012 does not prohibit the use of chemical anchor bolts. However, this code requires that chemical anchor bolts cannot be completely used during welding operations on rear embedded parts, and stipulates that mechanical bottom expansion anchor bolts should be used for rear embedded parts that require welding operations after being in place, or that chemical anchor bolts and mechanical anchor bolts should be arranged alternately. After more than half of the chemical anchor bolts are in place, welding operations on their components and connectors are not allowed. In summary, even if chemical anchor bolts can be used for fixation, they need to comply with corresponding regulatory requirements and pay attention to the drawbacks of chemical anchor bolts. If it cannot fully comply with the regulations, other feasible fixing methods such as mechanical anchor bolts need to be used.

3, Comparison of advantages and disadvantages between chemical anchor bolts and mechanical anchor bolts
The advantage of chemical anchor bolts is that they can be fixed in a certain depth of drilling without requiring too much space and tools, with simple operation and good fixation effect; Mechanical anchor bolts require enlarged holes and special tools for operation, which can be quite cumbersome. Chemical anchor bolts can also be grouted and solidified to enhance the fixation effect, but their agents cannot withstand high temperatures and are easily affected by external environments; Mechanical anchor bolts are not affected by external factors, are resistant to high temperatures, and are more suitable for heavy loads, vibrations, impacts, and other situations.
Overall, chemical anchor bolts and mechanical anchor bolts have their own advantages and different application scenarios. The specific selection and operation should be based on the specific situation to ensure the best fixation effect and construction efficiency.
