Our advantage:
Grout Sleeve is a mechanical splicing designed for the connection of precast elements.Each Grout sleeve features a threaded end (used for the connection to reinforcement at the precast factory) and a wide cavity to perform a grout connection at site.At the construction site, connection is made in a few seconds by injecting/pouring non-shrink grout into the cavity.
Performance:
- Mechanical Anchorage
- Low Cycle (large strains) fatigue performance
- Brittle Fracture resistance
OEM support.

The grouting sleeve is a combination of specially processed sleeves, matching grouting materials and steel bars. When the steel bars are coagulated, the fast-hardening shrinkage grouting material is injected, and the steel bars and the sleeves are connected by the bonding and occlusal effect between the materials. The sleeve grouting joint has the advantages of reliable performance, wide applicability and easy installation.
Features:
1. Stable performance: The grouting filling method does not apply any external force and heat to the steel bar, so it will not cause the expansion and contraction of the steel bar or generate residual stress;
2. Support customization: complete specifications, a large number of stock, can process customized products according to the needs of various departments with drawings and samples;
3. Standard process: the thread profile is good, the production is excellent, and the steel bar link strength is high.

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. |
