The utility model relates to a technical field of assembly type structure, especially an assembly type sleeve grout is connected or thick liquid anchor connects the technical field with the shutoff subassembly.
[ background of the invention ]
The prefabricated building is a whole building formed by connecting prefabricated concrete components through reinforcing steel bars, connecting pieces and the like and pouring concrete on site, meets the basic trend of building industrialization and housing industrialization actively advocated in China at present, and is beneficial to realizing the building targets of low carbon, environment protection and energy conservation.
The steel bar connection technology is one of the key technologies of prefabricated building, and reliable steel bar connection is the key for ensuring structural integrity and shock resistance. At present, the steel bar connection modes adopted by the assembly type building in China comprise three modes of sleeve grouting connection, slurry anchor connection and mechanical connection, and the sleeve grouting connection mode is adopted in many of the steel bar connection modes. The principle of sleeve grout is connected is to see through hollow sleeve, makes the reinforcing bar penetrate the sleeve inside from both ends opening, under the condition that need not overlap joint or welding, directly accomplishes the connection of reinforcing bar through the mortar of the little expanded structure performance of packing high strength between reinforcing bar and sleeve. The principle of grout anchor connection is that discontinuous reinforcing steel bars extending out of the surface of a prefabricated part for a certain length are inserted into a reserved hole channel at the corresponding position of the connected prefabricated part, and then non-shrinkage high-strength grouting material is filled between the reinforcing steel bars and the inner wall of the hole channel to form the grout anchor connection.
At present, due to the common phenomena of lack of technical training and worker on duty management and stricter construction quality management and the like and the defects of the existing technical standard in the field of domestic assembly type buildings, the assembly type buildings often have quality defects caused by insufficient grouting. The mainstream detection methods for grouting fullness are divided into a nondestructive detection method for the outside of a component and a sensor pre-embedding method for the inside of a grouting sleeve. The detection methods have the defects that the operation can be carried out only by personnel with professional training and specialized detection equipment, the cost is high, the detection methods are verified afterwards, and the problems existing in the grouting construction process cannot be found in time.
