Chemical anchor installation and use method
How to install chemical anchor? What is the method when using chemical anchors? The following small series will tell you about the installation and use of chemical anchors, I hope to help everyone.
Chemical anchor installation method
1. Drilling: According to the design requirements, according to the spacing of the drawings and the margins, the holes are drilled on the base layer. The hole diameter and hole depth must meet the design requirements.
2. clear the hole: use air pressure blow pipe and other tools to remove the floating ash and dust inside the hole, keep the hole clean.
3. Insert the drug tube: Insert the drug tube into the clean hole. When the resin can flow like honey under the condition of hand temperature, the hose can be used.
4. Drill into the chemical anchor: Screw the screw into the screw until the drug flows out. Electric drills generally use impact drills or hand drills with a drilling speed of 750 rpm. At this time, the chemical anchor is screwed in, the drug tube is broken, the resin, the curing agent and the quartz particles are mixed, and the gap between the chemical anchor and the pore wall is filled. At the same time, the anchor bolt can also be inserted into the wet hole, but the water must be drained out of the borehole, and the waiting time for the gelling process and the hardening process must be doubled.
5. Hardening process: Remove the installation tool and wait for the hardening of the agent. See the detailed information for the chemical reaction time.
6. the gel process: keep the installation tool does not move, the chemical reaction time see detailed information.
7. Fixed object: After the agent is completely hardened, add the washer and hex nut to fix the object.
How to use chemical anchors
1. According to the engineering design requirements, drilling holes in the corresponding position in the substrate (such as concrete), the hole diameter, hole depth and bolt diameter should be determined by professional technicians or field tests.
2. Drill holes with impact drills or water drills.
3. Use a special air pump, brush or compressed air machine to clean the dust in the drill hole. It is recommended to repeat it no less than 3 times. There should be no dust or clear water in the hole.
4. Ensure that the surface of the bolt is clean, dry and free of oil.
5. Confirm that the glass tube anchor bag has no abnormalities such as appearance damage and solidification of the drug, and put the round head into the anchor hole and push it to the bottom of the hole.
6. Use the electric drill and special installation fixture to insert the screw into the bottom of the hole with strong rotation. The impact method should not be used.
7. When screwing to the bottom of the hole or the position on the bolt, stop the rotation immediately, remove the mounting fixture, and avoid the disturbance before the gel is fully cured. The overtime rotation causes the glue to drain and affects the anchoring force. (The rotation time should not exceed 30 seconds, the rotation speed should not be lower than 300 rpm, no more than 750 rpm, the bolt advance speed is about 2 cm / sec, and the impact method is not allowed.)
The above is about the introduction of chemical anchor installation and use methods. I hope everyone can understand the installation and use of chemical anchors.
