  Note: 1. The bottom dimension in the table is the value of the sleeve raw material that meets the mechanical performance requirements of No. 45 steel in GB/T699-2015 (the measured yield strength and ultimate strength should not be less than J355-2015 Rebar Sleeve Grouting Connection Application Technology The standard specified in the regulations), the minimum size that can be selected when the sleeve manufacturer has a good level of quality control. 2. The minimum size of the measured sleeve should be measured in at least two directions, and the minimum value should be used for judgment. 3. The customer's special customized sleeve must meet the mechanical performance parameters (strength requirements) of the sleeve as a premise, and the size can be flexibly controlled.
