[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] In one embodiment, refer to the appendix to the specification. Figures 1 to 12 The present invention provides a prefabricated exterior wall panel fine-tuning connection device, comprising: a base 1 for pre-embedding in the building structure, a connecting seat 2 for connecting with the exterior wall panel, a first adjusting member 3, and a second adjusting member 4. The base 1 is provided with two spaced-apart first fixing blocks 11, each having a coaxially arranged first threaded hole 111. The connecting seat 2 is provided with a first arc-shaped groove 211. The first adjusting member 3 includes two first screws 31, each adapted to and connected to the corresponding first threaded hole 111. A first locking block 32 is connected to one end of each first screw 31 that is close to the other. A first column 321 is fixed to the top of each locking block 32 and inserted into the first arc-shaped groove 211. When the two first screws 31 are rotated, the connecting seat 2 can move on a first plane. The second adjusting member 4 includes a second screw 41. The connecting seat 2 is provided with a through hole 212. The second screw 41 passes through the connecting seat 2 and is adapted to be connected to the through hole 212. The end of the second screw 41 is held against the base 1. When the second screw 41 is rotated, the connecting seat 2 can move in a direction perpendicular to the first plane.

[0026] In this embodiment, the position of the connecting seat 2 on the horizontal plane can be adjusted by the first arc-shaped groove 211 in conjunction with the first adjusting member 3, and the position of the connecting seat 2 on the perpendicular plane can be adjusted by the second adjusting member 4. This device can achieve three-way adjustment of the connecting seat 2 with only two sets of adjusting members, requiring fewer accessories and simplifying the adjustment process. Furthermore, it eliminates the need to re-drill holes when the holes on the pre-embedded bolts and prefabricated exterior wall panels are misaligned, and it also eliminates the need to change the pre-embedded position of the bolts, thus improving work efficiency.

[0027] In one embodiment, refer to the appendix to the specification. Figures 1 to 7 The base 1 is provided with a first slot 12, which is located between two first fixing blocks 11. Two first locking blocks 32 are adapted to be disposed within the first slot 12. When the two first screws 31 are rotated, the two first locking blocks 32 can reciprocate within the first slot 12. By adapting the first locking blocks 32 to be disposed within the first slot 12, the first slot 12 can guide the first locking blocks 32, causing them to reciprocate along the axial direction of the first slot 12.

[0028] Furthermore, a first cap 112 is fixed to the side of each of the two first fixing blocks 11 away from the first slot 12, and a first threaded hole 111 passes through the first fixing block 11 and the first cap 112. By setting the first cap 112 on the first fixing block 11, the length of the first threaded hole 111 can be effectively extended, improving the structural stability of the first screw 31. A first adjusting part 311 is provided at the end of each of the two first screws 31 away from the first slot 32. The first adjusting part 311 extends to the outside of the first cap 112 and is used to rotate the first screw 31. The first adjusting part 311 can be a hexagonal structure. The hexagonal structure allows for easy tightening using general-purpose tools (adjustable wrench, hex wrench, etc.) without the need for specialized tools, thus improving the ease of operation.

[0029] Furthermore, a first collar 33 is fitted onto the first column 321. The end of the first column 321 has an external thread. The first column 321 passes through the first arc-shaped groove 211 and extends a predetermined length, so that the external thread of the first column 321 is located on the side of the connecting seat 2 away from the first locking block 32. The first collar 33 is adapted to fit within the first arc-shaped groove 211, and the first nut 34 is adapted to connect with the external thread of the first column 321. By fitting the first collar 33 onto the first column 321, the first locking block 32 can move easily within the first locking groove 12. By rotating the first adjusting parts 311 on both sides, the two first locking blocks 32 can move between the middle position and the side positions of the first locking groove 12. The two first locking blocks 32 being located at different positions in the first locking groove 12 allows for fine-tuning of the position of the connecting seat 2 on the first plane. The first plane is the plane where the base plate 21 is located, also known as the horizontal plane mentioned above. The horizontal plane mentioned here is just a specific description; of course, it could be any other plane.

[0030] In one embodiment, refer to the appendix to the specification. Figures 1 to 7 The connecting seat 2 includes a base plate 21, a side plate 22, and a stiffening plate 23. One end of the base plate 21 is perpendicularly and fixedly connected to one end of the side plate 22. The bottom of the stiffening plate 23 is fixedly connected to the base plate 21, and the side of the stiffening plate 23 is fixedly connected to the side plate 22. Multiple stiffening plates 23 can be provided, such as two or three. The side plate 22 is provided with mounting holes 221. The screws 222 on the exterior wall panel pass through the mounting holes 221 and are fitted and connected to the mounting nuts 223.

[0031] The first arc-shaped groove 211 is provided on the base plate 21. The base plate 21 is also provided with a through hole 212. The through hole 212 is located between the first arc-shaped groove 211 and the side plate 22. A second nut 213 is fixed on the side of the base plate 21 away from the side plate 22. The screw hole of the second nut 213 is coaxially arranged with the through hole 212.

[0032] The second screw 41 has a support portion 42 and a second adjustment portion 43 at both ends. The second screw 41 is adapted to pass through the second nut 213 and the through hole 212, such that the support portion 42 is located on the side of the base plate 21 closer to the base 1, and the second adjustment portion 43 is located on the side of the base plate 21 away from the base 1. The second nut 44 is adapted to connect with the end of the second screw 41 near the second adjustment portion 43. When the second adjustment portion 43 is turned, the connecting seat 2 can move in a direction perpendicular to the first plane, that is, in the vertical direction. The second adjustment portion 43 can be a hexagonal structure. The hexagonal structure allows for easy tightening with general-purpose tools (adjustable wrench, hex wrench, etc.) without the need for professional tools, thus improving the ease of operation.

[0033] In this embodiment, the position of the mounting hole 221 on the connecting seat 2 can be adjusted by the first adjusting member 3 and the second adjusting member 4, so that the mounting hole 221 is facing the screw 222 on the external wall panel, thereby realizing the installation and fixation with the screw 222 on the external wall panel. It is not necessary to re-drill holes when the pre-embedded bolts and the holes on the connecting seat of the prefabricated external wall panel are not in the same position, nor is it necessary to change the pre-embedded position of the pre-embedded bolts, thus improving work efficiency.

[0034] In one embodiment, refer to the appendix to the specification. Figure 2 , Figures 8 to 12 The prefabricated exterior wall panel fine-tuning connection device also includes a positioning component 5. Two spaced-apart second fixing blocks 13 are provided on the base 1, each with a coaxially arranged second threaded hole 131. The positioning component 5 includes a positioning plate 51 and two third screws 52. The positioning plate 51 has a second arc-shaped groove 511. The two third screws 52 are parallel to the first screw 31 and are adapted to the corresponding second threaded holes 131. A second locking block 53 is connected to one end of each third screw 52 that is close to the other. A second column 531 is fixed to the top of the second locking block 53 and inserted into the second arc-shaped groove 511. When the two third screws 52 are rotated, the positioning plate 51 can move on the first plane.

[0035] The base 1 is provided with a second slot 14, which is located between two second fixing blocks 13. Two second locking blocks 53 are adapted to be installed in the second slot 14. When the two third screws 52 are rotated, the two second locking blocks 53 can reciprocate within the second slot 14. By adapting the second locking blocks 53 to be installed in the second slot 14, the second slot 14 can guide the second locking blocks 53, causing them to reciprocate along the axial direction of the second slot 14.

[0036] Furthermore, two second fixing blocks 13 are respectively fixed with second caps 132 on the side away from the second slot 14, and second threaded holes 131 pass through the second fixing blocks 13 and second caps 132. By setting second caps 132 on the second fixing blocks 13, the length of the second threaded holes 131 can be effectively extended, improving the structural stability of the third screw 52. A third adjusting part 521 is respectively provided at the end of the two third screws 52 away from the second slot 53. The third adjusting part 521 extends to the outside of the second cap 132 and is used to rotate the third screw 52. The third adjusting part 521 can be a hexagonal structure. The hexagonal structure allows for easy tightening using general-purpose tools (adjustable wrenches, hex wrenches, etc.) without the need for specialized tools, thus improving operational convenience.

[0037] Furthermore, a second collar 54 is fitted on the second column 531, and an external thread is provided at the end of the second column 531. The second column 531 passes through the second arc-shaped groove 511 and extends out by a preset length, so that the external thread of the second column 531 is located on the side of the positioning plate 51 away from the second locking block 53. The second collar 54 is adapted to be installed in the second arc-shaped groove 511, and the third nut 55 is adapted to be connected to the external thread of the second column 531.

[0038] In this embodiment, by setting the positioning component 5, the positioning and installation of the connecting seat 2 can be assisted, thereby improving its installation convenience; in addition, the adjustment parts of the first adjustment component 3 and the positioning component 5 are both located on both sides of the base 1, which facilitates on-site installation and adjustment and improves on-site installation efficiency.

[0039] It should be noted that all components in the above embodiments can be steel components, and the fixed connection described above can be achieved by welding, or by threaded connection or other fixing methods.

[0040] In practical applications, please refer to the attached instruction manual. Figures 1 to 12 The specific assembly process of the prefabricated exterior wall panel fine-tuning connection device is as follows: Two second locking blocks 53 are placed in the second locking slots 14, and two third screws 52 are screwed into the second cap 132 from one side until they are screwed into the second locking blocks 53, so that the second locking blocks 53 and the third screws 52 are fixedly connected; two second pillars 531 are passed through the second arc-shaped grooves 511 on the positioning plate 51, and two second collars 54 are respectively fitted onto the corresponding second pillars 531, so that the two second collars 54 are properly fitted into the second arc-shaped grooves 511; finally, two third nuts 55 are connected to the corresponding second pillars 531, thereby realizing the connection and installation of the positioning plate 51 and the second locking blocks 53, and completing the assembly of the positioning component 5.
