HILTI chemical anchor bolts for the Rail system

Hilti HVU chemical anchor is a new type of steel anchoring material. The key is composed of chemical agents and metal material extruder screws. The chemical agent of chemical anchors is mainly composed of anti-corrosion vinyl resin, quartz stone particles, and epoxy. The curing agent is the key raw material and is also known as a chemical plug. Chemical anchors have excellent seismic grade and compressive strength characteristics. They are mainly used for building curtain wall structures, installing equipment, crane rail base plate or beam, steel frame structure protection fence, and fixing windows. Dynamic or structural reinforcement.

The relativity of Hilti HVU chemical anchor bolts and the advantages of mechanical equipment anchor bolts Corrosion resistance, low temperature, embrittlement, moisture resistance, stable long-term load in a humid and cold natural environment, excellent seismic performance, no swelling ground stress, and small height interval. Therefore, both chemical anchor bolts and mechanical equipment anchor bolts have different characteristics, and they must be purchased according to different application regulations when they are used.

How to use Hilti chemical anchor bolts

The use of chemical anchors is also relatively simple

1. First, according to the project regulations, open holes in the relative parts of the base material (rock, concrete, etc.)
2. Then use a special type air cylinder, brush, or air compressor to remove the dust in the punching hole, and repeat this no less than 3 times.
3. Ensure that the surface of the bolt is clean, dry, and free of oil stains.
4. Put the chemical agent into the drilled hole, use an electric hammer or electric drill and a special installation fixture to forcefully rotate the screw until the bottom of the hole, so as to achieve the purpose of breaking the glass tube and strongly mixing the anchoring agent. The rotation speed of the electric hammer or electric drill should be adjusted to a slow gear, and the impact method should not be used.

5. When the screw reaches the bottom of the hole or the marked position on the bolt, immediately stop the rotation, remove the installation fixture, and avoid disturbance after the gel is completely cured. Overtime rotation will cause the loss of glue and affect the anchoring force.
6. Visually check whether the curing is normal. The bolts of important parts need to be subjected to on-site pull-out tests to check whether their anchoring force meets the design requirements; the next process can be carried out only after being qualified
