Embodiment

[0029] Such as figure 1 , 4 As shown in and 9, the full grouting sleeve 1 for connecting steel bars in this embodiment includes two grouting sleeves, the first grouting sleeve 11 and the second grouting sleeve 12, the first grouting sleeve 11 or the second The grout barrel 12 is provided with a grout discharge hole 2. The two grouting sleeves are connected by threaded connection or by the connecting sleeve 5. The two grouting sleeves are respectively poured into the first grouting sleeve 11 and the second grouting sleeve 12 The grouting material is fixedly connected with the connected steel bars 4.

[0030] Such as Figure 1-3 As shown, the outer diameters of the two grouting sleeves are different, the outer diameter of the first grouting sleeve 11 is greater than the outer diameter of the second grouting sleeve 12, and the two grouting sleeves are connected by straight threads or taper threads to form a stepped shape. Split type full grouting sleeve 1.

Abstract

The invention relates to a full grouting sleeve for connecting steel bars. The full grouting sleeve comprises such two sections of grouting sleeves as a first grouting sleeve and a second grouting sleeve; the first grouting sleeve is provided with a grouting hole; the two sections of grouting sleeves are connected with each other by a thread or a connecting sleeve and are fixedly connected with steel bars to be connected through materials grouted into the grouting sleeves; the two sections of grouting sleeves are different in diameter; and the two sections of grouting sleeves are connected to form a stair-shaped detachable full grouting sleeve by a straight thread or taper thread and are connected by a cuttage grafting rotary thread structure. By adopting the full grouting sleeve for connecting the steel bars, the precast-in-place connecting beam segments for a fabricated concrete structure can be shortened, the use amount of templates and cast-in-place concrete can be reduced, the work load of casting concrete in place can be lowered, the construction speed can be increased, and the construction cost can be reduced.

Description

Technical field [0001] The invention relates to the technical field of the connection construction of precast concrete components of a fabricated concrete structure, in particular to a grouting connection structure of a precast concrete structure with a transverse steel reinforcement sleeve. Background technique [0002] At present, prefabricated concrete structure buildings are constructed using industrialized technology. The main structural components are prefabricated in the factory, and these prefabricated concrete components are installed and connected as a whole after arriving on site. This industrial production method greatly reduces the amount of wet work on the construction site , Which has significantly increased the construction speed, reduced environmental pollution and material consumption, and has become a new direction for the development of my country's construction industry. Rebar connection of prefabricated concrete structures is the key to structural safety. Reb...
