When mortar is stored in the mortar storage cavity 8, the mortar pre-stored in the mortar storage cavity 8 cannot leak out because the mortar outlet 6 is separated by the separation membrane 10 and the open end of the sleeve 7 is blocked by the blocking piece 20.
As shown in fig. 2, the plugging member 20 includes a plugging cover 11, a plugging block 12 for plugging the opening of the grouting hole 4 is fixed on one side of the plugging cover 11, the plugging block 12 is a rubber block and is connected in the grout storage cavity 8 in an interference manner, and one side of the plugging block 12 is attached to the end surface of the sleeve 7. A rubber plug 13 is arranged on one surface of the blocking block 12 far away from the blocking cover 11, a blocking seam 9 for communicating the inside and the outside of the sleeve 7 is arranged on the rubber plug 13, an insertion hole 14 corresponding to the blocking seam 9 is arranged on the blocking block 12 and the blocking cover 11 in a penetrating mode, and the opening direction of the insertion hole 14 is consistent with the length direction of the sleeve 7.
The sealing seam 9 is a gap penetrating through the rubber plug 13, the sealing seam 9 is formed by two surfaces in the rubber plug 13 in an abutting mode, the rubber plug 13 is made of rubber, and mortar is difficult to leak out of the sealing seam 9. When the embedded rib 3 passes through the insertion opening 14 and passes through the blocking seam 9, the blocking seam 9 surrounds and surrounds the embedded rib 3, so that mortar is difficult to leak out from the blocking seam 9.
The insertion opening 14 is used for inserting the embedded rib 3 on the floor slab 1, a flaring chamfer 15 is arranged in the opening of the insertion opening 14, a chamfer groove 16 is arranged on one surface, facing the blocking block 12, of the rubber plug 13, and the blocking seam 9 is communicated with the chamfer groove 16.

When the prefabricated wall body 2 is installed on the floor slab 1, when the embedded ribs 3 enter the grout storage cavity 8, the embedded ribs 3 are in contact with the elastic pieces 18 and push the elastic pieces 18 to be deformed towards a straight piece, and in the process, the split rings 19 advance outwards from the matching openings 24 and destroy the separating membranes 10, so that the grout storage cavity 8 is communicated with the external environment.
Example two:
the differences compared with the first embodiment are that:
as shown in fig. 5, the grouting hole 4 is a circular hole, a threaded sleeve 22 is coaxially fixed in the grouting hole 4, the sleeve 7 is a circular cylinder, an external thread is formed on the outer surface of the sleeve 7, the sleeve 7 is screwed in the threaded sleeve 22, and a communication port 23 corresponding to the matching port 24 is formed on the threaded sleeve 22. The sleeve 7 can be screwed onto the threaded sleeve 22, thereby fixing the sleeve 7 to the prefabricated wall 2.
Example three:
a method of constructing a prefabricated building structure according to the first aspect:

brushing and coating the outer surface of the sleeve 7 to form a glue layer, and then inserting the sleeve 7 into the contra-rotating grouting hole 4;
step three: the hoisting construction is carried out,
the prefabricated wall body 2 is hoisted so that the embedded bar 3 provided on the floor slab 1 passes through the caulking joint 9 from the insertion opening 14 and is inserted into the grout storage chamber 8.
The prefabricated wall body 2 is installed through the above steps, since mortar is prepared and injected into the sleeve 7 on site, thereby preventing the mortar from being cured due to long-term storage in the sleeve 7. The sleeve 7 can be quickly connected with the prefabricated wall body 2 by brushing glue on the outer surface of the sleeve 7 and then inserting the sleeve 7 into the grouting hole 4.
When the grout storage cavity is installed, the embedded ribs 3 directly penetrate through the plugging seams 9 through hoisting construction and are inserted into the grout storage cavity 8, when the embedded ribs 3 enter the grout storage cavity 8, the embedded ribs 3 are in contact with the elastic pieces 18 and push the elastic pieces 18 to be deformed towards the straight pieces, the split rings 19 advance outwards to the matching openings 24 in the process and break the separation membranes 10, so that the grout storage cavity 8 is communicated with the external environment, and the separation membranes 10 are not required to be additionally damaged by operation. Mortar is originally pre-stored in the mortar storage cavity 8, so that the mortar does not need to be slowly injected into the mortar storage cavity 8, and the installation progress of the prefabricated wall body 2 is accelerated.
In addition, the mortar amount in the mortar storage cavity 8 is not fully stored, and the mortar can be filled in the mortar storage cavity 8 after the embedded ribs 3 are inserted into the mortar storage cavity 8.
Example four:
as shown in fig. 5, a construction method for implementing the prefabricated building structure according to the second embodiment:
