In the last issue, we introduced the construction technology of chemical anchors. Some customers consulted whether this construction technology were for all chemical anchors? Was it suitable for inverted cone shaped chemical anchors? Before answering these questions, we feel it necessary to introduce to you what is the inverted cone shaped chemical anchor? What is the difference between an inverted tapered chemical anchor and a normal chemical anchor?
Everyone knows that the chemical anchor is a kind of fastening material. It consists of chemical agent and a metal rod. The special cement is used to fix the screw to the concrete substrate borehole to realize the composite part anchored to the fixture. The so-called inverted tapered shaped chemical anchor is the meaning of the chemical anchor determined by the type, that is, the diameter of the screw is determined, the effective buried depth is determined, and the adhesive is determined. The inverted cone shaped chemical anchor bolt is mainly used for fixing the anchor plate on the concrete base or directly fixing the base of the vertical keel concrete.
Compared with ordinary chemical anchors, inverted tapered shaped chemical anchors have the following differences:
1. Inverted cone shaped chemical anchor and ordinary chemical anchor have different appearance. This can be known by comparing the pictures online.

2. Different adhesive is used. The shaped anchor bolts need to be installed with injection-type planting bar adhesive, while the ordinary chemical anchors are installed with chemicals.
3. The force is not the same. After the shaped-type anchor uses injection-type planting bar adhesive, the corresponding adhesive layer is formed between the hole wall and the anchor bolt. After the glue is solidified, the shaped anchor can reach the mechanical locking effect similar to the mold-expanded anchor. The chemical anchor is fixed by means of chemical bonding of the chemical anchor and the wall of the hole.
4. Bearing capacity is different. Generally, the stress of the inverted tapered shaped chemical anchor bolt will be 5%-10% better than the ordinary chemical anchor bolt.
5. The price is different. The price of the general shaped anchor bolt and planting bar adhesive will be higher than the ordinary chemical anchor. However, the service life of ordinary chemical anchors is 2 years, while the life of inverted tapered shaped chemical anchors is 50 years. And the annual cost of inverted tapered chemical anchors is much lower.
The above is the difference between inverted tapered chemical anchor and ordinary chemical anchor. How to choose it depends on the actual situation. The normal chemical anchor should be selected for the project to be removed within 2 years. On the contrary, choose the inverted cone shaped chemical anchor (the brand with anti-humidity aging certification, such as Nanjing Mankate, 50 years warranty) If you have any questions about this, please feel free to contact Xiaoman~
