Background technology
Sleeve grouting connection is the main connection that prefabricated concrete structure builds vertical prefabricated components Reinforcement
Method, grouting quality of connection are the key points for influencing building safety.National sector standard《Bar connecting grout sleeve》JG/
T398 defines the requirement to grout sleeve structure and material,《Prefabricated concrete structure technical regulation》JGJ 1、《Reinforcing bar set
Cylinder grouting connection application technology code》Applications and examination of the JGJ355 to reinforcing bar grout sleeve connection method are made that clear and definite rule
It is fixed.When being produced using the precast concrete of pre-buried grout sleeve connection, longitudinally connected reinforcing bar and the grout sleeve one of component
End is linked together using mechanical joining methods, or in the grouting connecting cavity at the prefabricated end of connection reinforcing bar insertion sleeve, sleeve is put
Close in precast concrete bottom position and be fixed on component cheek board, sleeve lateral wall upper position is set to be used to be vented
With the slurry outlet of grouting material outflow and lower part close to set by prefabricated components bottom for the grout hole being in the milk into sleeve,
The outer surface of prefabricated components is drawn out to by connecting plastic tube, all being installed with each reinforcing bar of sleeved steel reinforcement cage, built-in fitting and
After fixing, casting concrete, then jolt ramming, maintenance shaping, are finally made the concrete prefabricated elements such as wall or column, prefabricated
External surface of structural member side wall leaves grouting and the pulp pore of each sleeve, and front part of dispatching from the factory is removed to member profile size, connection steel
Outside the position of muscle and grout sleeve is checked, also patency inspection is carried out one by one to the sleeve grout hole on component, slurry outlet
Look into, construction and installation scene is transported to after qualified, precast concrete is hung into specified structure layer assigned position with lifting equipment, is pacified
In the existing structure in lower part, during installation, the connection reinforcing bar that substructure is stretched out upwards is inserted respectively into the pre- of top installation
