Planting reinforcement is a technology widely used in building structure reinforcement. It injects reinforcement glue into concrete drilling holes and implants steel bars to enhance the load-bearing capacity of the structure. So how to plant steel bars well?
1. Classification of epoxy anchoring adhesive
Injection epoxy anchor adhesives are two types: epoxy and vinyl. Vinyl resin injection anchor adhesive has the advantage of fast curing, and it is difficult to have more advantages. If there is no problem of rushing the construction period, it is not recommended to use it. Although epoxy resin injection anchor adhesive cures slightly slower, its comprehensive performance in all aspects is far superior to vinyl resin injection rebar glue, and it is also the most commonly used injection rebar glue.
2. Application scope of epoxy anchoring adhesive
- Suitable for high-speed railways, highways, bridges, tunnels, subways and other occasions with high anchorage performance requirements
- Suitable for planting screws and steel bars on the base material in reinforcement and renovation projects.
- Installation of various equipment and pipelines, and fixing of curtain wall brackets.
- Bonding and fixing of wooden components, plastic components, and metal components.
3. How to inject chemical anchor epoxy?
(1) Drilling: Use an electric drill or drilling machine to drill holes. The drill bit size and drilling depth should strictly follow the requirements of the design drawings;
(2) Cleaning the hole: Brush the hole with a brush before implanting the steel bar or screw, then use an air compressor or air cylinder to blow out the dust, and repeat brushing and blowing the hole three times;
(3) Inject the mixed epoxy anchor adhesive from the open space to the hole mouth. The glue is generally filled to 2/3 of the hole depth.
(4) Slowly screw the steel bar or screw into the hole in the same direction, and pull it up several times to make it sticky evenly. Do not disturb it during the curing time.
(5) According to the substrate temperature, wait for the anchoring epoxy to completely cure. After completely cured, the load can be installed.
4. Recommendations for concrete anchor epoxy
- Modified epoxy resin, no styrene
- High strength & modulus, good toughness
- Aging resistance & thermal resistance
- Moisture tolerant, stable in a humid environment
- Acid & alkali resistance
- Seismic resistance, no expansion forces
- Excellent thixotropy, suitable for side and top anchoring
- Binocular straight mixed package, with special electric caulking gun and static mixer
