The grouting device mainly comprises a flange die 90, a grouting sleeve 100 and an auxiliary positioning device. The auxiliary positioning device is connected with the grouting sleeve 100 and is matched with the flange mold 90. The flange mold 90 can be enclosed to form a molding cavity for casting, that is, the shape of the molding cavity formed by enclosing the flange mold 90 is the shape of the prefabricated member. The grout sleeve 100 is used to cast and mold the prefabricated components into a whole, so that different prefabricated components can be assembled and connected in special occasions. And the auxiliary positioning device is used for positioning and fixing the grouting sleeve 100 so as to ensure the position accuracy requirement of the grouting sleeve 100.

The edge blocking mold 90 is provided with a preformed hole to facilitate the assembly of the auxiliary positioning device and the grouting sleeve 100. In particular, the preformed hole is a circular through hole.

With continued reference to fig. 1 and 2, in an alternative embodiment, the auxiliary positioning device includes: at least two ring pieces 10, a squeezing block 20, an actuating rod 30 and an actuating body 40. When the prefabricated part is produced and processed, at least two ring sheets 10 need to be preassembled in the inner cavity of the grouting sleeve 100, at least two ring sheets 10 are arranged along the circumferential direction and are surrounded to form an accommodating cavity, and the radial diameter surrounded by each ring sheet 10 is smaller than the diameter of the inner cavity of the grouting sleeve 100, so that the ring sheets 10 can move close to or away from each other. The extrusion block 20 can be movably arranged in the accommodating cavity; the actuating rod 30 can penetrate through the edge blocking die 90 and is in driving connection with the extrusion block 20; the actuating body 40 is in driving connection with the actuating rod 30, and can drive the actuating rod 30 to drive the extrusion block 20 to extrude the ring pieces 10 to be far away from each other.

In the auxiliary positioning device, the ring piece 10 and the extrusion block 20 can be matched to form a pre-assembled positioning assembly, the actuating rod 30 and the actuating body 40 can be matched to form an actuating fixing assembly, and the pre-assembled positioning assembly and the actuating fixing assembly can be flexibly assembled and disassembled according to use requirements. Specifically, before the prefabricated part is cast, at least two ring sheets 10 may be pre-installed in the grouting sleeve 100, and at the same time, the extrusion block 20 is pre-installed in the accommodating cavity defined by the at least two ring sheets 10 and is guaranteed to move well. The grouting sleeve 100 can then be assembled with the reinforcing mat and lifted vertically in its entirety into the casting area enclosed by the flange form 90. And then, the actuating rod 30 penetrates through the preformed hole on the edge blocking mold 90 and then is connected and fixed with the extrusion block 20, and finally, the actuating body 40 is firmly connected with the actuating rod 30, so that when a constructor operates the actuating body 40, the actuating body 40 can drive the actuating rod 30 to move relative to the edge blocking mold 90, further drive the extrusion block 20 to move and extrude the ring pieces 10 from the inside to expand outwards to be away from each other, the expanded ring pieces 10 can tightly abut against the grouting sleeve 100 from the inside due to the increase of the whole volume, and finally the grouting sleeve is tightly fixed on the edge blocking mold 90, thereby achieving the purpose of positioning and fixing the grouting sleeve 100. After the prefabricated member is poured and formed, the actuating rod 30 and the actuating body 40 can be firstly detached, then the prefabricated member is integrally separated from the edge blocking mold 90 in a vertical mode (demolding), finally all the ring sheets 10 and the extrusion blocks 20 are detached from the grouting sleeve 100, and at the moment, the grouting sleeve 100 is left in the prefabricated member to be integrated. Compared with the traditional positioning device, the auxiliary positioning device in the technical scheme can enable the reinforcing mesh and the grouting sleeve 100 to be integrally and vertically hoisted during pouring operation, is favorable for finishing reinforcement binding work in advance, and is favorable for vertical hoisting and demolding after the prefabricated part is formed, so that the production efficiency is improved; and the connecting strength and rigidity of the preassembly positioning component and the actuating fixing component are high, and the durability and reliability can be greatly improved.

With reference to fig. 1, fig. 2, fig. 6 and fig. 7, in order to facilitate understanding of the technical solution of the present application, in an embodiment, the actuating rod 30 is a screw rod, the actuating body 40 is a nut, and the nut is screwed on the screw rod; the extrusion block 20 is provided with a threaded hole 24, the screw rod comprises an assembly end, and the assembly end penetrates through a preformed hole preset on the edge blocking die 90 and then is screwed in the threaded hole 24. Therefore, the screw rod and the extrusion block 20 can be quickly assembled and disassembled, the use requirements of different stages of procedures in the forming and processing of the prefabricated part are met, and the connecting mode is high in strength structure and good in reliability.

It is emphasized that the screw is screwed into the threaded hole 24 to a sufficient depth to prevent the screw from being removed from the threaded hole 24 when the nut drives the screw, thereby preventing the movement of the ram 20.

With continuing reference to fig. 4 and fig. 6, in an embodiment, the ring piece 10 includes a base plate 11 and a first fitting block 12 disposed on the base plate 11 and far away from the edge-blocking mold 90, the first fitting block 12 is provided with a first tapered surface portion 121, the pressing block 20 is provided with a second tapered surface portion 21, and the first tapered surface portion 121 and the second tapered surface portion 21 are fitted and attached; wherein the inclination directions of the first tapered surface portion 121 and the second tapered surface portion 21 are both: and is inclined toward the actuating rod 30 in a direction from the grout sleeve 100 to the flange mold 90. In addition, in order to make the overall structure of the auxiliary positioning device compact and improve the positioning effect, in a preferred embodiment, the number of the ring pieces 10 is four, and the ring piece 10 further includes a second matching block 13 disposed on the base plate 11 and close to the edge blocking mold 90, the second matching block 13 is provided with a first inclined surface 131, an arc-shaped surface and a second inclined surface 133 which are sequentially disposed, and the adjacent first inclined surface 131 and the second inclined surface 133 can be fitted together in a matching manner, so that the four ring pieces 10 can be surrounded to form a cylindrical barrel. Therefore when four ring pieces 10 are assembled in the grouting sleeve 100, the ring pieces 10 can be closely attached without interference through the first inclined surface 131 and the second inclined surface 133, so that a cylindrical barrel with a compact structure is formed, the four arc-shaped surfaces are circumferentially connected to form an arc wall through hole, a screw rod can be well penetrated and arranged in the through hole, the screw rod is guided and radially limited, and the screw rod is guaranteed to stably move.

When the grouting sleeve 100 is positioned, the nut is rotated, and can drive the screw to move towards the direction far away from the grouting sleeve 100 by virtue of the transmission characteristic of the thread pair; at this time, the extrusion block 20 can move synchronously with the screw, the second tapered surface portion 21 gradually adheres to and further wedges the first tapered surface portion 121, the first tapered surface portion 121 receives the extrusion force of the second tapered surface portion 21, so that the ring pieces 10 expand outwards and are away from each other, and finally, the outer wall surface of the ring piece 10 abuts against the inner wall surface of the grouting sleeve 100 to achieve limiting. Particularly, since the first engaging block 12 is disposed at a position of the substrate 11 far from the edge-blocking mold 90, when the ring piece 10 is pressed by the internal pressing force of the pressing block 20, one end close to the edge-blocking mold 90 is almost immovable, and the end provided with the first conical surface portion 121 can move outward in a large range, so that the assembly of the four ring pieces 10, which is initially a cylindrical barrel, is changed into a conical barrel, and the large end of the conical barrel can abut against the inner wall of the grouting sleeve 100, and along with the further movement of the pressing block 20, the grouting sleeve 100 can be pushed to abut against the edge-blocking mold 90, thereby better completing the positioning operation.

Alternatively, the first tapered surface portion 121 provided on the first fitting block 12 may be an inclined plane or a circular arc surface 132. In this embodiment, preferably, the first conical surface portion 121 includes four inclined arc surfaces 132, and the arc surfaces 132 are designed to have a gradually decreasing diameter, i.e., the radial diameter of the arc surfaces 132 tends to decrease gradually from the grouting sleeve 100 to the flange mold 90. Thus, the ring piece 10 can be matched with the second cone portion 21 to form a wedging action, and under the extrusion action of the second cone portion 21, the ring piece expands outwards to abut against the grouting sleeve 100.

Still referring to fig. 6, the extrusion block 20 suitably includes an annular convex body 22 and an extrusion main body 23 connected to each other, in an embodiment, the extrusion main body 23 is a square body, four surfaces of the extrusion main body 23 are all inclined surfaces, and the four inclined surfaces are abutted against four inclined arc surfaces 132 on the ring sheet 10 in a one-to-one correspondence manner during assembly, so as to ensure uniform stress. Of course, in other embodiments, the extrusion body 23 may be rounded or tapered.

With continued reference to fig. 3 and 4, the corner edges of the pressing body 23 are engaged in the mating gaps of two adjacent ring segments 10. Specifically, four ring pieces 10 are circumferentially arranged to form four matching gaps, four corner edges of the extrusion main body 23 are just clamped in the four matching gaps in a one-to-one correspondence manner, and circumferential rotation can be prevented when the extrusion block 20 moves under the limiting effect of the side wall of the ring piece 10.

The first matching block 12 and the second matching block 13 are arranged at intervals to form a groove 50, and the annular convex body 22 is clamped in the groove 50. Therefore, the extrusion block 20 can be prevented from falling into the deep position of the grouting sleeve 100 due to no limit constraint in the installation process; in addition, under the side wall limiting effect of the first matching block 12, when the screw is screwed into the threaded hole 24 of the extrusion block 20, the extrusion block 20 cannot retract backwards, and smooth assembly can be ensured.

Specifically, the number of the first rotation preventing surfaces 81 is two, and the first rotation preventing surfaces are oppositely arranged at intervals. The second anti-rotation surfaces 31 are planes extending in the axial direction of the screw, and are also two in number and arranged oppositely at intervals. And the distance between the two second rotation preventing surfaces 31 is equal to the distance between the two first rotation preventing surfaces 81. After the screw rod is sleeved on the anti-rotation sleeve 80, the first anti-rotation surface 81 and the second anti-rotation surface 31 are tightly attached to each other, so that the screw rod can be prevented from rotating along with the nut when the nut is screwed, and finally the nut cannot be smoothly screwed.

It should be noted that the screw is a screw with a plane at one end, and can be made by machining a common screw. In the case where the screw can be stopped, the rotation preventing sleeve 80 can be omitted.

Further, in order to avoid the use of an auxiliary tool, which also facilitates the turning of the nut, and thus the movement of the drive screw, the outer wall of the nut is provided with a turning handle.
