As shown in fig. 1 to 2, the present embodiment provides a prefabricated member bar connecting device including a first bar 1 provided in a prefabricated member, a second bar 2 provided in concrete to be installed in the prefabricated member, a bar connecting sleeve 3 provided at an end of the first bar 1 and the second bar 2 and connecting the first bar 1 with the second bar 2, an inner ring portion 7 provided in the bar connecting sleeve 3, a plurality of outer ring portions 6 provided at an outer side edge of the bar connecting sleeve 3 and in a longitudinal direction, a lower grouting pipe 4 and an upper grouting pipe 5 provided on the bar connecting sleeve 3, communicating with an inside of the bar connecting sleeve 3 and extending to an outside of the prefabricated member, a lateral pipe 8 connected to the lower grouting pipe 4 or the upper grouting pipe 5, a longitudinal pipe 9 connected to the lateral pipe 8 and forming a T-shape together with the lateral pipe 8, a grouting funnel 10 provided at a top of the longitudinal pipe 9 and storing grouting liquid, and a plugging rod 11 provided at an outer side end of the lateral pipe 8. The extrusion plugging rod 11 comprises a plugging head 111, a plugging handle 112 and an extrusion rod 113 which are connected in sequence. In the present embodiment, the diameter of the blocking head 111 is equal to the inner diameter of the lateral pipe 8, and the diameter of the pressing rod 113 is smaller than the inner diameter of the lateral pipe 8. In addition, the lower end of the longitudinal duct 9 is bent toward the reinforcing bar coupling sleeve 3 and communicates with the lateral duct 8.

Taking the prefabricated column as an example, the steel bar connecting sleeve 3 is sleeved on the lower portion of the first steel bar 1 and prefabricated in the prefabricated column, the lower portion of the steel bar connecting sleeve 3 is flush with the lower portion of the prefabricated column, and the lower grouting pipe 4 and the upper grouting pipe 5 extend out of the prefabricated column. After the prefabricated column is hung to the installation position, the second steel bar 2 is inserted into the steel bar connecting sleeve 3, so that grouting can be performed. The grouting liquid is stored in the grouting funnel 10, and the lower grouting pipe 4 or the upper grouting pipe 5 is connected by the inner side of the transverse pipeline 8. In this embodiment, the outside of the transverse pipe 8 is plugged by the plug 111, and the grouting liquid enters the reinforcing steel bar connecting sleeve 3 under the action of self weight. For example, when the lateral pipe 8 is connected to the lower grouting pipe 4, when the upper grouting pipe 5 has grouting liquid flowing out, it is indicated that the steel bar connecting sleeve 3 is full of grouting liquid. In order to ensure grouting filling in the steel bar connecting sleeve 3, the extrusion plugging rod 11 is taken down, and the extrusion rod 113 is inserted into the transverse pipeline 8 and the lower grouting pipe 4 to perform extrusion vibration. Under the action of extrusion vibration, grouting liquid is filled in the steel bar connecting sleeve 3.

In this embodiment, in order to fill up the grouting inside the reinforcing bar connecting sleeve 3, the inner ring part 7 may be provided as a spiral pipe communicating with the lower grouting pipe 4 and the upper grouting pipe 5, and a plurality of grouting liquid discharge holes 71 for entering the reinforcing bar connecting sleeve 3 into grouting liquid are formed inside the spiral pipe. And, both the top and bottom of the spiral pipe are not blocked, which communicates with the outside only through the lower and upper grouting pipes 4 and 5. Wherein, the grouting liquid can easily pass through the spiral pipe and is discharged from the grouting liquid discharge hole 71, thereby effectively solving the problems that the friction resistance of the grouting liquid in the steel bar connecting sleeve 3 is large and the grouting filling of the steel bar connecting sleeve cannot be realized due to the rough surface of the steel bar and the like.

The above embodiments are only preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model, but all changes made by adopting the design principle of the present utility model and performing non-creative work on the basis thereof shall fall within the scope of the present utility model.
