Embodiment

[0029] like figure 1 , 4 As shown in and 9, the full grouting sleeve 1 for steel bar connection in this embodiment includes two sections of grouting sleeves, which are respectively the first grouting sleeve 11 and the second grouting sleeve 12, the first grouting sleeve 11 or the second grouting sleeve The grouting tube 12 is provided with a grouting hole 2, and the two sections of the grouting sleeve are connected by threads or through the connecting sleeve 5, and the two sections of the grouting sleeve 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 bar 4 .

[0030] like Figure 1-3 As shown, the outer diameters of the two sections of grouting sleeves are different, the outer diameter of the first grouting sleeve 11 is larger than the outer diameter of the second grouting sleeve 12, and the two sections of grouting sleeves are connected by straight threads or tape...

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 prefabricated concrete member connection construction of an assembled concrete structure structure, in particular to a prefabricated concrete structure transverse reinforcement sleeve grouting connection structure. Background technique [0002] At present, prefabricated concrete structures are constructed using industrial technology, and their main structural parts are prefabricated in factories. After arriving at the site, these prefabricated concrete components are installed and connected into a whole. This industrial production method greatly reduces the amount of wet work on the construction site. , 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. The steel bar connection of prefabricated concrete structures is the key to the structural safety. The steel bar...
