1. The HRB400 grade steel bar strength standard value is: fyk=400N/mm2, fstk=570N/mm2.

2. Ifa hole is made with a rhinestone, the anchoring depth is increased by onetime on the basis of the table.

3. The margin, spacing and structure of the planting barshall comply with the provisions and requirements of the“Technical Regulations for Post-Anchor of Concrete Structures”and“Code for Design of Concrete Structure Reinforcement”. The anchorage depth of the steel bars in the table shall not consider the spacing of the steel bars and the bearing capacity of the margins. The impact of specific projects is subject to design.

4. Whether the glue layer is full will directly affect the anchoring force.

5. The data in the table only considers the force of a single steel bar under a single load single working condition, and the actual anchoring depth is subject to the single design.

6. The concrete grade of the concrete used for planting steel bars should not be lower than C20, and has a certain volume. The steel bars should not be planted in weathered, severely cracked, uncompacted concrete.

7. Each group of injection-type rubber can use the calculation formula of the number of implants: n=360,000/(0.785×0.66×d2 ×h)=700,000/( d2 ×h). Where d is the Diameter of drilling hole and h is the depth of the hole, both in mm;

8. In addition to being used for concrete substrates, the planting rubber can be used for solid masonry such as various types of stone, ALC block, shale modular brick, clay brick, etc.
