More preferably securely, the phenomenon that increasing wall body intensity, preventing sleeve from bursting.
2. the utility model, using the design thickeied, keeps entire grout sleeve more secured at sleeve, bigger is withstood forces.
3. the utility model connects into one using grouting mouth, thick liquid discharge mouth and sleeve body using secured, gapless mode
Body, it can be ensured that grouting, pulp plastic tube are completely embedded, reliably with reinforced concrete grouting branch sleeve in component production, are not necessarily to
Other fixations are carried out to grouting, pulp plastic tube, therefore the requirement to grouting, the installation of pulp plastic tube can be reduced, significantly
The production efficiency of prefabricated components is improved, production cost is reduced.
4. the utility model is using the back-off being arranged in grouting mouth and thick liquid discharge mouth so that in the defeated pipe of grouting mouth and thick liquid discharge mouth
Installation can be more secured, and the back-off of design increases friction area, and entire filling process is made more to stablize.

Specific implementation mode
The utility model is further described with reference to specific embodiment：
Embodiment 1：
Half grout sleeve of one kind as depicted in figs. 1 and 2 comprising have sleeve body 1, sleeve body 1 is axial to offer phase
Intercommunicated threaded portion and grouting inner cavity, 1 side of sleeve body forms the grouting mouth 3 and thick liquid discharge mouth 2 of connection grouting inner cavity, institute
It states grouting intracavity sidewall lower end and is provided with several annular protruding ribs 5, the grouting intracavity sidewall top axial is provided with several reinforcements
Muscle 6.The logical portion opened up in half grouting, one side protrudes the grouting mouth 3 formed and a thick liquid discharge mouth 2, when two reinforcing bars
When being connected and fixed, the reinforcing bar in logical portion both sides is set, is mutually compressed, grouting is squeezed into from grouting mouth, waits for filling up in sleeve body 1
When, which squeezes out from thick liquid discharge mouth 2, is arranged and plays a kind of fixed grouting liquid in the fin 5 and reinforcing rib 6 being in the milk in inner cavity,
The phenomenon that keeping two bar connectings more preferably secured, while increasing wall body intensity, preventing sleeve from bursting.
As shown in Figures 2 and 3, the utility model is further arranged to, the reinforcing rib 6 include the first reinforcing rib 6 with
Second reinforcing rib 6, grouting inner cavity medial surface are provided with the first reinforcing rib 6, and opposite with first reinforcing rib 6 is another
Side is provided with second reinforcing rib 6 opposite with first reinforcing rib 6.Two be provided with along inner wall at this smaller end of bore
Root reinforcing rib so that tube conformation is increasingly complex, after grouting liquid pours into, since slurries are injected from grouting mouth 3 from the bottom up, directly
It overflows from thick liquid discharge mouth 2 and flows out to slurries, upper end position bears wall or other pressure, makes it by other positions of comparison sleeve
More external pressures are set, the use of reinforcing rib 6 can bear the pressure of bigger, while after grout cures, due to
The reinforcing rib 6 added makes intracavity contact area expand, extraordinary fixed function is played to the slurries of solidification.
As shown in Fig. 2, the utility model is further arranged to, circumferential ramps are provided in the grouting inner cavity, the inclined-plane
The intracavity diameter in left side is less than the intracavity diameter on the right side of inclined-plane, and the fin 5 is arranged on the right side of plasma discharge inner cavity.It is filled on traditional market
Mouth end is starched, logical portion one end is arranged in using connectivity kit, although such design can screw logical portion one end, largely
Working hour and cost, a kind of conical design of use are expended, i.e., the internal circumferential ramps presented are effectively reduced the wave of resource
Take, and operation is more simple.
The utility model as shown in Figure 2 is further arranged to, and the wall thickness in 1 left side of the sleeve body thickeies, in figure
It is evident that the position thickeied, since from the analysis on mechanics, which needs to bear the power of bigger, so use herein
Design is thickeied, the ability to bear of sleeve is enhanced.
As shown in Fig. 2, the utility model is further arranged to, the grouting mouth 3 and thick liquid discharge mouth 2 are both provided with mounting portion 4；
