The difference and characteristics of mechanical anchors and chemical anchors

First of all, the two methods of reinforcement are very different. The mechanical anchor bolt adopts the principle of mechanical lock key to anchor and lock. Among them, the chemical anchor bolts are cemented and fixed on the concrete base material with chemical agents to achieve the anchoring of the fixing parts.

The second is the difficulty of operation. Mechanical anchor bolts, like ordinary anchor bolts, have lower requirements for installers. However, the implantation of chemical agents with chemical anchors requires manual operation, which may be difficult.

The third is the long duration. Due to the use of metal materials, mechanical anchors are not subject to construction restrictions, and the installation speed is relatively fast. Moreover, chemical anchor bolts involve the use of chemical agents, so a period of curing time is required. The duration will be extended. The fourth is the difference in high temperature resistance and solderability. Due to the use of chemical raw materials, chemical anchors have a relatively low melting point and are significantly weaker in high temperature resistance than mechanical anchors with higher melting points of metal materials . The resulting mechanical anchors are weldable due to high temperature resistance, so use The scenes are more diverse.

The fifth point is the seismic level. Compared with mechanical anchor bolts, chemical anchor bolts have lower seismic resistance. When subjected to irregular loads such as earthquakes, mechanical anchors can play a better anchoring role. It can prevent secondary disasters caused by house collapse. Only a few mechanical anchors in my country have undergone rigorous earthquake simulation tests.

Application scope: 1. Installation and fixing of various pipelines and cable brackets such as railways, tunnels, bridges; 2. Suitable for connection and fixing of curtain walls; 3. Installation of various anti-theft doors, anti-theft windows and fire doors; 4. Each This kind of pipeline is installed and fixed in civil buildings.

The characteristics of mechanical anchor bolts: 1. Compared with other ordinary anchor bolts, the drill hole diameter is smaller, and it has strong tensile, fatigue, and seismic properties; 2. The materials are different according to the use environment, The anti-corrosion performance is also different; 3. A wide range of applications, suitable for concrete substrates of various strengths, and other substrates that are not suitable for planting rubber; 4. Simple structure, corrosion resistance, abrasion resistance, high temperature resistance, good weldability, suitable for Any environment that is not suitable for planting glue.
