Detailed Description
The present invention will be described in further detail with reference to examples.
This embodiment provides a novel grout sleeve entirely, as shown in fig. 1 and 2, including both ends opening and hollow sleeve body 1, the upper portion lateral wall of sleeve body 1 is equipped with grout outlet 4, and middle part lateral wall department is equipped with the locating tenon mounting hole, and the locating tenon mounting hole interpolation has reinforcing bar locating tenon 5, and the lower part lateral wall of sleeve body 1 is equipped with slip casting mouth 3. The side wall of the sleeve body 1 is provided with a plurality of hoop ribs 6, one hoop rib 6 is located between the grouting opening 3 and the lower end opening of the sleeve body 1, one hoop rib 6 is located between the grout outlet 4 and the upper end opening of the sleeve body 1, three hoop ribs 6 are located between the grouting opening 3 and the positioning tenon mounting holes, and three hoop ribs 6 are located between the grout outlet 4 and the positioning tenon mounting holes. The side wall of the sleeve body 1 is provided with 8 hooping ribs 6 in total, 1-3-3-1, so that the bonding and biting force of grouting material in the sleeve and the bonding and biting force of concrete of a component outside the sleeve can be enhanced simultaneously. The middle of the sleeve is provided with a steel bar positioning tenon 5 for determining the insertion length of the steel bar. In this embodiment, the bottom flaring of sleeve body 1 is the horn type, and during the member connection of being convenient for, the bottom reinforcing bar inserts, and simultaneously, when the lower reserved reinforcing bar is the tilt state, because the design of horn mouth, the reinforcing bar tip of slope can support on the inner wall of horn mouth, and the in-process of inserting is under the guide of horn mouth inner wall, and the reserved reinforcing bar is progressively held up straight.
