Intensity, makes bar connecting solid and reliable.
2nd, the inner convex platform and inner groovy size in the utility model grouting cavity wall are more or less the same, common mechanical processing technique
Processing request is realized, casting and the difficulty of processing of sleeve is reduced.
3rd, sleeve one end of the present utility model is connected provided with screwed hole with screw thread steel, and the other end anchors steel by grouting material
Muscle so that joints size is obviously reduced, and ensure that connection is firm.
4th, one end outer wall of the sleeve of the present utility model provided with screwed hole is provided with external groove, when both facilitating with bar connecting
Screw, can also improve the fixing intensity between sleeve and concrete.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is enlarged drawing at the A in Fig. 1,
Fig. 3 is use state schematic diagram of the present utility model.
Wherein, 1 is sleeve, and 2 be slip casting cylinder, and 3 be the slurry cylinder that overflows, and 4 be external groove, and 5 be connection end bar, and 6 be end of thread steel
Muscle, 7 be grouting material, and 8 be screwed hole.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figures 1 and 3, the utility model includes sleeve 1, is used for and spiral shell provided with screwed hole 8 in described one end of sleeve 1
Line end bar 6 is connected, and is axially looked along sleeve 1, and with one heart, reinforcing bar pair can be so effectively ensured in the screwed hole 8 and sleeve 1
In, in the present embodiment, the screwed hole 8 uses steep-pitch thread to increase pulling force, and the other end of the sleeve 1 is openend,
And provided with grouting chamber in the sleeve 1, connection end bar 5 is that the openend on the sleeve 1 is inserted into the grouting
Intracavitary, in the side of the grouting chamber away from the screwed hole 8 provided with slip casting cylinder 2, the grouting chamber is close to the screwed hole 8
