Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and more specifically, to an anti-fall-off device for fixing building curtain walls. Background Technology

[0002] A building curtain wall refers to the non-load-bearing exterior wall cladding of a building, typically composed of panels (glass, metal, stone, ceramic, etc.) and a supporting structure behind them (aluminum beams and columns, steel structures, glass ribs, etc.). A building curtain wall is an exterior envelope or decorative structure composed of a supporting structural system and panels, capable of some displacement relative to the main structure, and does not share the loads of the main structure. It is a non-load-bearing, curtain-like structure, hence also called a suspended wall, and is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It is a building envelope structure composed of a structural frame and inlaid panels, which does not bear the loads or actions of the main structure.

[0003] For example, utility model CN221255837U discloses a building curtain wall. Its working principle is as follows: When installing the building curtain wall, it is first placed within the installation frame. Then, under the rotation of the rotating mechanism, the drive tube rotates. Through the threaded engagement of the drive tube and the threaded rod, and the guiding action of the guide assembly, the limiting rod at one end of the sliding plate moves closer to the building curtain wall. During this movement, when the limiting rod is inserted into the limiting hole on the building curtain wall and abuts against the bottom wall of the limiting hole, the drive tube continues to rotate. This causes the extrusion plate to slide on the elastic cavity and compress the spring, generating elastic force. Through the spring's elastic force, the limiting rod is pushed to maintain contact with the building curtain wall. This ensures the secure installation of the building curtain wall while providing the necessary expansion and contraction space for deformation under high temperatures, allowing thermal stress to be released. This reduces the risk of the building frame deforming due to high temperatures, further ensuring the normal service life of the building curtain wall.

[0004] Regarding the above-mentioned solutions: The inventor believes that the above-mentioned reference documents use the rotation of the drive tube to push the sliding plate into the curtain wall and maintain abutment connection with the curtain wall, but the stability of the curtain wall is not high enough and it lacks the effect of preventing the curtain wall from falling off, which makes the curtain wall prone to falling off. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Example:

[0026] A device for fixing and preventing falling off a building curtain wall includes a wall 1, a curtain wall 2 on one side of the wall 1, and an anti-falling mechanism on one side of the curtain wall 2. The anti-falling mechanism includes a rotating rod 31 rotatably connected to one side of the wall 1, a gear 32 fixedly connected to one side of the rotating rod 31, a first hollow groove 35 on one side of the curtain wall 2, and the gear 32 located inside the first hollow groove 35. A first rack 33 is provided on the upper side of the gear 32, and a second rack 34 is provided on the lower side of the gear 32. The first rack 33 and the second rack 34 are both meshed with the first rack 33. A second hollow groove 36 and a third hollow groove 37 are provided inside the curtain wall 2, and the third hollow groove 37 and the third hollow groove 37 are both connected to the first hollow groove 35.

[0027] The rotating rod 31 and gear 32 can be placed inside the first hollow groove 35 to support and fix the curtain wall 2, making it less likely to fall off. The gear 32 can rotate to drive the first rack 33 and the second rack 34 on the upper and lower sides to move in opposite directions. The first rack 33 and the second rack 34 can move into the second hollow groove 36 and the third hollow groove 37 respectively to further increase the contact area with the curtain wall 2. This can make the support effect better and make the curtain wall 2 less likely to move, with better stability, and thus less likely to fall off.

[0028] Please see Figure 3 A first threaded groove 41 is provided on one side of the curtain wall 2. A bolt 43 is threadedly connected inside the first threaded groove 41. A second threaded groove 42 is provided on one side of the gear 32. The bolt 43 is threadedly connected inside the second threaded groove 42. The bolt 43 can be connected to the inside of the first threaded groove 41 and the second threaded groove 42 to fix the gear 32, making it less likely for the gear 32 to come off the first hollow groove 35. This makes the curtain wall 2 more stable and less likely to come off the rotating rod 31 and the gear 32. At the same time, the bolt 43 can also be rotated out of the second threaded groove 42, which makes it easier to replace the curtain wall 2.

[0029] Please see Figure 3 A hollow block 51 is fixedly connected to one side of the wall 1. An L-shaped slide rod 52 is slidably connected inside the hollow block 51. A fourth hollow groove 53 is opened on the outer side of the rotating rod 31, and the L-shaped slide rod 52 is located inside the fourth hollow groove 53. The hollow block 51 can support the L-shaped slide rod 52, so that the L-shaped slide rod 52 can be stably placed on the upper side of the rotating rod 31. At the same time, the L-shaped slide rod 52 can also move into the interior of the fourth hollow groove 53 to limit the rotating rod 31, making it difficult for the rotating rod 31 to rotate, thereby making the gear 32 more stable.

[0030] Please see Figure 3A support ring block 61 is provided on the outer side of the rotating rod 31. A reinforcing rod 62 is fixedly connected to the outer side of the support ring block 61, and the reinforcing rod 62 is fixedly connected to the wall 1. The reinforcing rod 62 can support and fix the rotating rod 31 through the support ring block 61, so that the rotating rod 31 is not prone to deformation and breakage. The support ring block 61 can also ensure that the reinforcing rod 62 supports the rotating rod 31 without hindering the rotation of the rotating rod 31.

[0031] Please see Figure 3 A limiting groove 71 is provided on one side of the wall 1. A limiting block 72 is rotatably connected inside the limiting groove 71. The limiting block 72 is fixedly connected to the rotating rod 31. Both the limiting groove 71 and the limiting block 72 are T-shaped cylinders, so that the limiting groove 71 can limit the limiting block 72, making it difficult for the limiting block 72 to move. At the same time, the limiting block 72 can also limit the rotating rod 31, so that the rotating rod 31 is not easy to detach from the wall 1 when it rotates on one side of the wall 1.

[0032] Please see Figure 2 The wall 1 is fixedly connected to the first magnet block 81 inside the second hollow groove 36. The first rack 33 is fixedly connected to one side of the second magnet block 82, and the second magnet block 82 and the first magnet block 81 attract each other. The mutual attraction of the first magnet block 81 and the second magnet block 82 makes the first rack 33 more stable when it moves into the second hollow groove 36 and less prone to movement. At the same time, the first magnet block 81 and the second magnet block 82 are also provided on one side of the second rack 34, which makes the second rack 34 more stable.

[0033] Please see Figure 4 A fifth hollow groove 91 is provided on one side of the curtain wall 2. A support rod 92 is installed inside the fifth hollow groove 91 of the curtain wall 2, and the support rod 92 is fixedly connected to the wall 1. The fifth hollow groove 91 can be moved into the interior of the support rod 92 to further reinforce the curtain wall 2, making the curtain wall 2 more stable on one side of the wall 1 and less likely to fall off.

[0034] The working principle and usage process of this utility model are as follows: When using this device, the curtain wall 2 is first moved into the outer side of the rotating rod 31 and gear 32 through the first hollow groove 35, so that the gear 32 is located inside the first hollow groove 35 to support the curtain wall 2. Then, the rotating rod 31 is rotated to drive the gear 32 to rotate. The gear 32 will drive the first rack 33 and the second rack 34 to move in opposite directions. After that, the first rack 33 and the second rack 34 will move into the interior of the second hollow groove 36 and the third hollow groove 37 respectively to further increase the contact area with the curtain wall 2. This can make the support effect better and make the curtain wall 2 less likely to move, with better stability, so that it is less likely to fall off. At the same time, the reinforcing rod 62 can support and reinforce the rotating rod 31 through the supporting ring block 61, so that the rotating rod 31 is less likely to deform and break. This solves the problem that the stability of the curtain wall 2 is not high enough and the anti-falling effect of the curtain wall 2 is lacking, which makes the curtain wall 2 prone to falling off.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
