[0004] In the prior art, patent CN206233504U discloses a back-mounted interior wall crystalline calcium board installation structure. This involves drilling holes in the wall, fixing a keel frame with expansion screws, and finally installing decorative panels through the keel frame. This method requires drilling holes in the wall, embedding the connecting structure into the existing wall, and then installing the decorative panels or wall panels to the connecting structure. This necessitates drilling relatively deep holes into the wall to ensure the stability of the connecting mechanism during installation; it can easily damage the wall itself and reduce the overall stability of the wall. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an external wall connection structure that solves the technical problem that drilling holes in the wall during the installation of existing wall connection structures can damage the wall.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0015] Preferably, two mounting hubs are fixedly installed on one side of the connecting fixing block, and the mounting hubs have mounting connection holes.

[0016] Preferably, two identical fixing screws are fixedly installed at the lower end of the wall mounting plate, and the diameter of the fixing screws is equal to the diameter of the mounting connection hole.

[0017] Preferably, the spacing between the fixing screws is equal to the spacing between the two mounting holes.

[0018] Preferably, the insulation layer, flame-retardant board, and wall decoration board are fixedly installed on the side of the keel frame away from the wall mounting plate.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are:

[0020] This utility model allows for the installation of the connecting mechanism without damaging the wall by pre-reserving an installation hole in the wall support body, installing the fixed base and connecting frame inside the wall support body, and extending one side of the connecting frame with the connection hole out of the wall.

[0029] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0030] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses an external wall connection structure, such as... Figure 1 As shown, the system includes a fixing part installed inside the wall support body 1. Specifically, an installation hole is pre-reserved at the installation location of the wall support body 1, and the fixing part is embedded inside the installation hole of the wall support body 1. The remaining space inside the installation hole is filled with filler material 11. In this embodiment, the filler material 11 is a resin fiber material. After the resin fiber material cures, it allows the fixing part to connect with the wall support body 1. By pre-reserving the installation hole and filling it with resin fiber material after installing the fixing part, the stability of the wall support body can be maintained. Commonly used resin filler materials in construction include epoxy resin, vinyl ester resin, phenolic resin, etc., which can be used to fix steel, wood, etc. It is also understood that expanded perlite, polystyrene particles, or vermiculite mortar can also be used for filling and fixing.

[0031] It also includes a connecting part and a mounting part, with the fixing part movably connected to the connecting part, and the connecting part movably connected to the mounting part. For example... Figure 1 , Figure 2 , Figure 3 As shown, the fixing part includes a fixing base 12, and connecting frames 13 are fixedly installed on both sides of the fixing base 12; as Figure 1 , Figure 2As shown, the surfaces of the fixed base 12 and the connecting frame 13 are filled with filler material 11. The filler material 11, the fixed base 12, and the connecting frame 13 are all installed inside the wall support body 1. It should be noted that one end of the connecting frame 13 extends out of the wall support body 1, and a connecting hole is provided at the end of the connecting frame 13 that extends out of the wall support body 1.

[0032] like Figure 1 , Figure 3 As shown, the connecting part includes a connecting threaded rod 14, which passes through the connecting holes of the connecting frames 13 on both sides of the fixed base 12. The length of the connecting threaded rod 14 is greater than the length between the connecting frames 13, ensuring that both ends of the connecting threaded rod 14 extend out of the connecting frames 13. Both ends of the connecting threaded rod 14 are threaded with a first nut 15.

[0033] like Figure 1 , Figure 3 As shown, a wall panel connecting and fixing block 16 is fitted onto the threaded surface of the connecting threaded rod 14. Two mounting hubs 17 are fixedly installed on one side of the connecting and fixing block 16, and mounting hubs 17 have mounting connection holes. The connecting and fixing block 16 has a continuous threaded rod connecting hole inside, the diameter of which is equal to the diameter of the connecting threaded rod, for the connecting threaded rod 14 to pass through. It should be noted that the length of the connecting and fixing block 16 is equal to the length between the two connecting frames 13. It can be understood that by placing the connecting and fixing block 16 between the two connecting frames 13 and passing it through the connecting threaded rod 14, and tightening the first nuts 15 on both sides of the connecting threaded rod 14 toward the connecting and fixing block 16, the connecting and fixing block 16 can be fixedly positioned between the connecting frames 13.

[0034] like Figure 1 As shown, the installation component includes a wall mounting plate 18 and a frame 2, as... Figure 4 As shown, the wall mounting plate 18 is fixedly mounted on one side of the keel frame 2, and the connecting fixing block 16 is connected to the wall mounting plate 18 through the mounting hub 17. Two identical fixing screws are fixedly mounted at the lower end of the wall mounting plate 18. The diameter of these two fixing screws is equal to the diameter of the mounting connection hole on the mounting hub 17, and the distance between the two fixing screws is equal to the distance between the two mounting connection holes. The two fixing screws of the wall mounting plate 18 are engaged in the two mounting connection holes, and then the second nut 19 is used to fix the wall mounting plate 18 to the mounting hub 17.

[0035] like Figure 4 As shown, the insulation layer 21 is fixedly installed on the side of the keel frame 2 away from the wall mounting plate 18, and the flame-retardant plate 22 is fixedly installed on the side of the insulation layer 21 away from the keel frame 2; the wall decoration plate 23 is fixedly installed on the side of the flame-retardant plate 22 away from the insulation layer 21.

[0036] Understandably, the size and length of the keel frame 2 can be adjusted according to requirements; the number and position of the wall mounting plates 18 set on the keel frame 2 can also be adjusted according to requirements. For example, for stability, a wall mounting plate 18 can be set at the top and bottom ends or at the four corners of the keel frame 2. Correspondingly, corresponding fixing parts or corresponding openings can be pre-embedded in the corresponding positions in the wall support body 1 for connecting the keel frame.

[0037] By installing the fixed base 12 and the connecting frame 13 inside the wall support body 1, there is no need to drill holes in the wall, which can ensure the stability of the wall and the connection strength between the connecting structure and the wall. The connecting threaded rod 14 and the first nut 15 are used to fix the connecting fixing block 16, which facilitates subsequent installation. The keel frame 2 is installed on the wall support body 1 by the cooperation of the wall mounting plate 18, the second nut 19 and the installation hub 17, which can realize the quick installation of the keel frame 2. At the same time, when it needs to be replaced, it can also achieve the effect of quick disassembly.

[0038] Working principle:

[0039] First, according to the design requirements, the layout is done in advance to determine the number of keel frames to be installed, the size of each keel frame, and the number of wall connection plates required for each keel frame. Then, the installation holes are reserved in the wall.

[0040] A connecting frame 13 is fixedly installed on both sides of each fixed base 12. Then, each fixed base 12 and connecting frame 13 are installed into the pre-reserved installation hole of the wall support body 1, with the side of the connecting frame 13 with the connecting hole exposed outside the wall support body 1.

[0041] Then, filler material 11 is used to fill around each fixed base 12 and connecting frame 13 until the wall support body 1 is fully filled.

[0042] After the filling material has cured, the user connects the connecting part to each fixed part. Specifically, the connecting fixing block 16 is fitted onto the connecting threaded rod 14, and then the connecting threaded rod 14 is installed into the connecting holes of the two connecting frames 13, with the side with the mounting hub 17 facing upward. Then, the first nuts 15 are installed on both sides of the connecting threaded rod 14 and tightened.

[0043] Finally, the keel frame 2, which has been pre-installed with the insulation layer, fire retardant board, wall decoration board and wall mounting plate 18, is transported to the corresponding position. The two fixing screws at the lower end of the wall mounting plate 18 of the keel frame 2 are aligned with the installation connection holes of the corresponding installation hub 17. Then, the two fixing screws are inserted into the installation connection holes. Next, two second nuts 19 are installed from below the installation hub 17 to fix the wall mounting plate 18.

[0044] When users need to replace the wall or inspect the inside of the wall, first unscrew the second nut 19 from the fixing screw under the wall mounting plate 18, then lift the keel frame 2 to separate the wall mounting plate 18 from the mounting hub 17, so that the wall support body 1 and the keel frame 2 can be inspected separately.

[0045] This connection method will not compromise the overall stability of the wall support structure 1, while also making the connection structure of the wall more stable.

[0046] By reserving installation holes during the construction of the main wall support structure, and by using the installation of connecting and fixing bases and connecting frames as a base, and then filling the area around the connecting and fixing bases and connecting frames inside the main wall support structure with filling material, the connection mechanism can be installed without damaging the wall, thus ensuring the stability of the wall.

[0047] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
