EspañaMechanical anchor bolts are materials used to improve object restraint and are widely used in reinforcement projects. It is also more suitable for the construction industry, such as installing railings on highways and bridges. For different materials, there are different types of anchor bolt performance. Below we compare the performance of mechanical anchor bolts and chemical anchor bolts:
1. Seismic resistance: The chemical anchor material has a slightly lower resistance, low tensile and shear resistance, so the seismic resistance is basically less than 7, and the screw material of the mechanical anchor has greater resistance. It has a strong tensile strength, so it has a strong shock resistance, which can reach level 8. Therefore, from the perspective of seismic resistance, mechanical anchors are the first choice. The processing of customized mechanical anchor bolts is called expansion bolts. The expansion bolt uses the relative movement of the cone and the expansion piece to promote the expansion of the expansion piece, and generates expansion force and extrudes together with the concrete. Pull out from the hole wall and generate tension through shear friction to make the connection an anchor component. According to different methods of expansion force control during installation, expansion anchors are divided into torque control type and displacement control type. The former is torque controlled, and the latter is displacement controlled.
2. High temperature resistance: due to the use of chemical raw materials, chemical anchor bolts have a low melting point, and the ability to withstand high temperatures is obviously weak; mechanical anchor bolts are metal materials with a higher melting point, and mechanical anchor bolts are weldable, so that Its use is more flexible.
3. Reliability: Due to the level of the construction personnel and the incomplete cleaning of the chemical anchor bolts, the chemicals cannot fully function, thereby reducing the durability of the clamping force. The metal materials used in the mechanical anchors have better performance. Therefore, Helps maintain retention for a long time.
After the above comparison, our understanding of mechanical anchors is one step closer. In terms of shock resistance, high temperature resistance and reliability, mechanical anchors are better than chemical anchors. Mechanical anchor bolt is a kind of rear anchor connection technology widely used in Chinese engineering circles. The basic principle of chemical anchor bolts is the same as that of attached anchor bolts, but chemical anchor bolts and long screws are similar to cast-in-place concrete steel bars because their lengths are not limited, and the form of damage is easy to control. Usually, it can be controlled as damage to the anchor. Therefore, it is suitable for anchoring connection of structural members or non-structural members with static and seismic fortification strength≤8. However, for the choice of different anchor bolts, different choices must be made according to the purpose.
