[0026] See also Figure 1-5 The utility model provides a technical solution: an embedded part sleeved on the end of a steel bar 10, the embedded part includes a base 1, a fixing rod 2, the fixing rod 2 is arranged on the upper part of the base 1, a blind hole is opened in the embedded part, the blind hole extends from the lower part of the base 1 to the upper part of the fixing rod 2, the blind hole is used for inserting the steel bar 10, and also includes:

[0027] Expansion piece 11, expansion piece 11 is arranged on the embedded part, steel bar 10 passes through expansion piece 11, expansion piece 11 has an expanded state, in the expanded state, expansion piece 11 abuts against steel bar 10; expansion piece 11 is arranged at the lower part of base 1, after steel bar 10 passes through expansion piece 11, expansion piece 11 is located between base 1 and steel bar 10 at this time, when expanding, the volume of expansion piece 11 increases, expansion piece 11 will be closely attached to the outside of steel bar 10, thus realizing the effect of sealing the gap between steel bar 10 and base 1, avoiding concrete pouring into the gap, and making it more convenient to disassemble the embedded part;

[0028] A pressurizing mechanism, which is used to drive the expansion member 11 to expand; the pressurizing mechanism includes a flow guiding chamber 8, a compression chamber 9, and a piston column 3. The flow guiding chamber 8 and the compression chamber 9 are both provided on the base 1. The flow guiding chamber 8 and the compression chamber 9 are connected. The lower end of the flow guiding chamber 8 is connected to the expansion member 11, and the piston column 3 is slidably connected in the compression chamber 9. By moving the piston column 3 downward, the medium in the compression chamber 9 can be squeezed into the flow guiding chamber 8, and then flows into the expansion member 11 through the flow guiding chamber 8. In this way, the expansion member 11 will expand after the medium flows into it, so as to achieve the sealing between the steel bar 10 and the base 1;

[0029] The sliding member includes a sliding sleeve 5 and an extension plate 6. The sliding sleeve 5 is slidably sleeved on the fixed rod 2, and the extension plate 6 is fixedly installed on the sliding sleeve 5. When the prefabricated wall panel is produced, the position of the sliding member on the embedded member can be changed, so that the extension plate 6 can overlap the upper edge of the mold, so as to ensure that the embedded member can be in a fixed position to avoid downward movement during the casting process;

[0030] The self-locking structure is used to lock the position of the sliding member. The sliding member is fixed by the self-locking mechanism.

[0031] In another embodiment of the present invention, a connecting rod 4 is included, the lower end of the connecting rod 4 is mounted on the piston column 3, and the upper part of the connecting rod 4 is detachably mounted on the extension plate 6. The upper part of the connecting rod 4 is provided with an external thread, and the upper part of the connecting rod 4 penetrates the extension plate 6. The upper part of the connecting rod 4 is threadedly connected with a nut 7, and a pair of nuts 7 are respectively abutted against the upper and lower surfaces of the extension plate 6. By not setting the connecting rod 4 on the piston column 3, the connecting rod 4 and the extension plate 6 are connected. When the extension plate 6 moves downward, the piston column 3 can be driven to move downward to achieve the expansion of the expansion member 11. It is necessary to set additional parts to drive the piston column 3, and through the setting of the nut 7, the distance between the extension plate 6 and the piston column 3 can be adjusted. In this way, corresponding adjustments are made according to the different distances between the upper edge of the mold and the upper surface of the concrete to ensure that the depth of the embedded part placed in the concrete is sufficient.

[0032] The expansion member 11 is arranged in the bottom opening of the base 1, and the expansion member 11 is arranged as a circular ring air bag. The expansion of the air bag can pressurize the steel bar 10, and also has a centering effect, so that the embedded part and the steel bar 10 are concentric, so that the position of the groove formed by the embedded part is more accurate.

[0033] The self-locking structure is configured as a bolt, which is threadedly connected to the sleeve 5, and one end of the bolt contacts the outer surface of the fixing rod 2. By tightening the bolt, one end of the bolt contacts the outer surface of the fixing rod 2, so that the sleeve 5 and the fixing rod 2 are fixed. When forming the embedded part, it is necessary to loosen the bolt, move the sleeve 5 upward, so that the piston column 3 moves upward synchronously, and the expansion member 11 contracts. Then, re-tighten the bolt, and gently tap the embedded part with a rubber hammer to loosen the embedded part and the concrete, and then hold the extension plate 6 and lift it up to realize the removal of the embedded part.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
