Mechanical anchor bolts and chemical anchor bolts are currently the most critical standard parts on the market at this stage. In the eyes of many laymen, they should be similar, but in fact there are still differences between them. The first is that there are different structural reinforcement methods. The chemical anchor mainly relies on putting the organic chemical tube into the hole, or pressing a part of the medicine in the container into the hole according to the caulking gun, and putting it into the hole. The extruder screw will support the cracking of the drug tube, and the extruder screw can bite tightly in the wall hole by the pre-tightening force caused by the drug tube. The mechanical anchor bolt uses the basic principle of the mechanical code lock key of the extruder screw to carry out the reinforcement of the fixed card.
The construction methods of different chemical bolts are different, which will lead to the difference in the construction cycle time. Since the chemical anchor bolts use organic chemicals to carry out the anchoring of the steel bars, it takes a lot of time to make the chemical agent. Sufficient dryness, and exceeding the temperature at which the organic chemical is condensed can easily lead to the deterioration of the anchorage quality of the steel bars. For projects with too tight construction time, chemical anchors are not a good choice.
However, mechanical anchor bolts will not have such problems. If the holes are well anchored, they can be applied immediately. The quality of the anchoring of the steel bars will not suffer all the hazards, which can save a lot of time. Also, in terms of the difficulty coefficient of actual operation, if the chemical anchor bolts achieve a stronger practical effect of anchoring steel bars, it is necessary to remove the dust and sediment in the tidy holes to maximize the contact between the organic chemical agent and the plate. It has the effect of steel anchoring, and it is also necessary to skillfully introduce organic chemicals into the holes, which are all to improve the difficulty coefficient of steel anchoring.
The relativity of chemical anchor bolts and the advantages of mechanical anchor bolts are corrosion resistance, ultra-low temperature, embrittlement, moisture resistance, long-term load stability in wet and cold natural environment, excellent seismic grade characteristics, no swelling ground stress, and small height interval. Therefore, both chemical anchor bolts and mechanical anchor bolts have different characteristics, and they must be purchased according to different application regulations when they are used.
