Full grouting sleeve Steel full grouting sleeve Can come to map custom grouting sleeve Steel grouting sleeve Reinforcing steel sleeve grouting connection technology refers to the grouting sleeve with ribbed steel bars inserted into the inner cavity as a concave-convex surface, by pouring a special high-strength cement-based grouting material into the gap between the sleeve and the steel bar, and anchoring the steel bar in the sleeve after the grouting material solidifies. A rebar connection technique for prefabricated elements.

In this technology, the grouting sleeve is pre-buried in the concrete member, and the grouting material is injected into the sleeve from the outside of the prefabricated member through the grouting pipe at the installation site to complete the connection of the steel reinforcement of the prefabricated member. , mainly used for the connection of stressed steel bars of various assembled monolithic concrete structures.

Sleeve grouting material for steel bar connection is a dry mix composed of cement as the basic material, with fine aggregates, concrete admixtures and other materials. Performance, dry powder filling in the gap between sleeve and ribbed steel bar, referred to as "sleeve grout" Technical features of the sleeve: 1 It is suitable for the connection construction of steel bars in the reinforced concrete structure of various structures that bear the two-way force of tension and compression. 2. Material saving, energy saving, not limited by the composition and type of steel bars. 3 can be connected in all directions. 4. It can be prefabricated in advance, factory-like operation, does not occupy the construction period, and can be constructed around the clock. 5 The operation is convenient and fast, and the construction speed is fast, which can greatly shorten the construction period.

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.
