Determine the location, burial depth, and precise positioning of the drill hole according to the design requirements of the planted steel bar. Select the corresponding drill bit according to the diameter of the planted steel bar, and use an electric hammer drill or diamond drilling equipment. Drilling
To clean the hole with chemical seeding, use a powerful soot blower to remove the concrete dust in the hole before implanting the steel bar, and then use a special hole cleaning brush to clean the hole wall. Repeat the hole cleaning at least times. If you use diamond drilling equipment to drill the hole, , the accumulated water in the hole must be cleaned up to ensure that there is no ash, water, or grease in the hole
Surface treatment of planted bar reinforcements uses mechanical methods or wire brushes to remove the rust and oxide layer on the surface of the seeded steel bars. Oil stains can be removed with acrylic copper. , in order to increase the bonding force between steel bars and structural glue
Glue injection is based on the anchor glue application form used in the construction of steel bars, pipe-mounted type, mechanical injection type, on-site configuration type and the direction of planting bars is upward, downward, horizontal Different methods should be used to inject glue to ensure that there are no bubbles or gaps in the hole. The amount of glue injected is generally about 1/2 of the depth of the hole.
Chemical rebar implantation will implant the processed steel bars into the hole in a continuous rotation method. Depth, the anchoring glue should just overflow the hole is the best
During the curing period of the anchoring glue for reinforcement and curing, do not disturb the steel bars and do not apply torque. The curing time is affected by the temperature of the base material and the brand of anchoring glue. Strictly follow the anchoring Glue production instructions construction.
This project should be completed by a professional construction company
