Precast Column Wall Embedded Parts Splicing Rebar Coupler Grouting Sleeves
Product description:
Product name: Reinforced grouting sleeve
Product material: 45# steel
Surface treatment: annealing treatment
Product category: full grouting/semi-grouting
Scope of application: reinforced concrete structures in various industrial and civil buildings, housing construction projects, water conservancy projects, bridge construction, etc...
Our advantage:
1. Complete logistics system: Our production base has a targeted transportation team to ensure customer delivery needs;
2. National certification authority test report, won the national ISO9001 quality system certification;
Features:
The appearance is in the shape of a hollow aid, and its length and wall thickness are calculated according to the applicable scene;
The installation is convenient, the hoisting of the components is carried out separately from the coagulation operation of the steel bars, that is, the components are hoisted in place first, and then the grouting material is injected to keep the components suspended;
The friction between the sleeve and the concrete is enhanced, and the surface is extruded by a precision mold to form unevenness, which greatly enhances the bonding strength of the sleeve and the concrete.

| 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. |
