by Illustration of key process of prefabricated building construction sleeve grouting ↓↓↓ as the key process of prefabricated building construction, sleeve grouting is used for the connection of vertical components (such as shear wall and frame column) and horizontal components (such as frame beam): the purpose of sleeve grouting is to insert ribbed reinforcement into the reinforcement sleeve with groove in the inner cavity, and then pour special high-strength Non shrinkage grouting material can achieve the connection effect higher than the strength of reinforcement base material: ▲ schematic diagram of semi grouting joint ▲ schematic diagram of full grouting joint preparation before construction [material preparation] key points of sleeve inspection: strength, deformation, spheroidization rate, hardness and other key points of grouting material inspection: strength, deformation, fluidity, durability and other key points of type inspection: tensile strength and deformation, Jgj107 primary joint standard [machine preparation] [key points of pre work preparation] 1 Inspection records (quantity, diameter and reserved length of joint reinforcement) 2 Base course cleaning (grout surface, sleeve interior, joint reinforcement) 3 Plugging (segmented or controlled quantity, curing) 4 Interface watering and wetting 5 Example of construction process of remedial plan [key points for construction] 1 Grouting construction (no mixing, mix proportion, watering and wetting, speed control) 2 Curing 3 Examples of sleeve grouting connection of three components of ambient temperature 1 – precast concrete shear wall connection 2 – precast concrete frame column connection 3 – precast concrete frame beam connection construction engineering Luban Award appreciation of construction engineering Luban exchange daily selection, release in the evening, combine learning with fun, make common progress ↓ long press identification, join the alliance ↓..
