Planting bar and planting glue (1)

The so-called planting reinforcement is in the structure reinforcement, reinforcement and other projects, in accordance with the reinforcement diameter used in the engineering design on the existing concrete structure or component, drilling with appropriate drilling diameter and depth, and using planting reinforcement glue to make the new component and the original concrete bond firmly, so as to achieve the function of planting reinforcement and anchoring. So what are the design and construction requirements of planting reinforcement and planting reinforcement glue?


It can be seen from the failure form that the effect of planting reinforcement engineering is closely related to the original concrete, planting reinforcement glue and reinforcement. In order to avoid the occurrence of abnormal pull-out failure and ensure the reinforcement effect of planting reinforcement, the following measures should be taken in the design and construction of planting reinforcement:
 
1. If planting reinforcement is used for anchoring, the concrete at the anchorage part shall not have defects, otherwise, the defective parts shall be reinforced.
 
2. Bond strength of planting bar glue
 
In this process, the function of planting reinforcement glue is to bond the reinforcement and concrete hole wall tightly through high-strength bonding force, forming a very strong bond anchoring force. This anchoring force can effectively resist the shear force and pull-out force borne by the reinforcement, so that the old and new components are firmly connected together, so as to achieve the purpose of reinforcement. It can be seen that the bond strength of planting bar glue has a great influence on the planting bar. Therefore, we should choose the high-strength adhesive according to the specification.
