Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall installation, in particular to an anti-falling device for a building curtain wall. Background Art

[0002] The building curtain wall is the outer protective structure of the building. It is hung outside the main structure of the building and does not bear the weight of the building. Instead, it is connected to the main structure of the building through special connectors.

[0003] The main function of the curtain wall is to protect the interior space of the building from the influence of the external environment while providing natural lighting and ventilation. The curtain wall system consists of the following main parts: supporting structure, panels, sealing and filling materials, connecting parts and fixing systems, and functional layers. The supporting structure is usually a structure made of aluminum alloy frame, steel frame or other alloy materials, which is used to support and fix the curtain wall panels; the panels of the curtain wall can be glass, metal plates, stone, ceramic panels or other synthetic materials. Glass panels are the most common choice because they can provide good light transmittance and aesthetics; sealing and filling materials are sealing strips, gaskets and adhesives used to prevent water and air penetration and sound insulation; connecting parts and fixing systems connect the curtain wall structure to the main structure of the building to ensure the stability and safety of the curtain wall; functional layers such as insulation layers, UV protection layers, safety layers, etc., which can be integrated into the curtain wall system to improve its performance.

[0004] However, when the curtain wall is installed, a frame for fixing will be installed at the edge of the curtain wall. The frame is fixed on the surface of the building to prevent the curtain wall inside the frame from shaking due to the impact of external force for a long time. Filling material will be injected between the inside of the frame and the curtain wall, which is not only used for sealing, but also has a certain function of fastening the curtain wall. However, the filling material may undergo chemical reactions after being exposed to external weather changes for a long time. When the curtain wall is impacted by external force and transmitted to the filling material, it is easy to cause the filling material to break or separate into powder, causing the curtain wall to shake easily inside the frame, increasing the risk of the curtain wall detaching from the inside of the frame. In view of this, a building curtain wall anti-falling device is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a building curtain wall anti-falling device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-falling device for a building curtain wall comprises an anti-falling frame, a threaded limiting block is fixedly connected to the front side of the anti-falling frame, a threaded rod is spirally connected to the threaded limiting block, a rotating plate is fixedly connected to the top end of the front side of the threaded rod, an extrusion plate is rotatably connected to the top end of the rear side of the threaded rod, a fixed block is fixedly connected to the rear side of the anti-falling frame, a pasting plate is fixedly connected to the top end of the front side of the fixed block, a buffer plate is fixedly connected to the front end surface of the pasting plate, a plug rod is fixedly connected to the middle of the front end surface of the pasting plate, a rubber layer is fixedly connected to the outside of the plug rod, the outside of the rubber layer contacts the curtain wall body, slots are opened on the upper and lower sides of the curtain wall body, a soft film is fixedly connected to the top end of the front side of the plug rod, and a conical plate is fixedly connected to the front end surface of the soft film.

[0007] As a further description of the above technical solution: the rear end face of the extrusion plate contacts the upper and lower sides of the front end face of the curtain wall body, the front end face of the buffer plate contacts the rear end face of the curtain wall body, and the rear end face of the soft film contacts the front side of the curtain wall body. The curtain wall body stuck on the inside of the anti-falling frame can be reinforced to prevent the curtain wall body from being stuck in the anti-falling frame and shaking due to external force, causing the building curtain wall to detach from the wall panel.

[0008] As a further description of the above technical solution: the number of the anti-falling frames is two groups, and the anti-falling frames are distributed on the upper and lower sides of the curtain wall body. The inner width of the anti-falling frames is 1.5 times the thickness of the curtain wall body, and sufficient space is reserved for the structure of the front end face of the fixed block and the structure inside the threaded limit block. Not only are the structures of the front end face of the fixed block and the structure inside the threaded limit block in contact with the curtain wall body, but filling material can also be injected into the inner side of the anti-falling frames.

[0009] As a further description of the above technical solution: there are several fixing blocks, and the fixing blocks are horizontally distributed in the middle of the inner rear of the anti-falling frame. The distance between the fixing blocks is twenty centimeters. Different numbers of fixing blocks can be set according to curtain wall bodies of different lengths to reduce the probability of the curtain wall body falling off from the inner side of the anti-falling frame.

[0010] As a further description of the above technical solution: the positions of the slots opened on the upper and lower sides inside the curtain wall body are perpendicular to the positions of the fixing blocks, and the diameter of the slots opened inside the curtain wall body matches the cross-sectional diameter of the insertion rod, so that the curtain wall body can be fixed inside the anti-falling frame to prevent the curtain wall body from being offset inside the anti-falling frame due to the impact of external force.

[0011] As a further description of the above technical solution: the threaded limit blocks are fixed on the front side of the anti-falling frame and there are several of them, and the distance between the threaded limit blocks is forty centimeters. When the plug rod is inserted into the curtain wall body, the curtain wall body is pushed toward the inner and rear side of the anti-falling frame to improve the stability of the curtain wall body inside the anti-falling frame.

[0012] As a further description of the above technical solution: the overall shape of the conical plate is a conical disc, and the cross-sectional diameter of the top end of the front side of the conical plate matches the cross-sectional caliber of the slot, the cross-sectional diameter of the soft film is twice the caliber of the slot, and the overall shape of the soft film is the same as the shape of the conical plate, which is a conical disc. After the conical plate, which is a cone as a whole, is inserted into the slot of the curtain wall body, the extrusion plate can be reduced in combination with the soft film. When the extrusion plate does not squeeze the curtain wall body, it still limits the curtain wall body and is difficult to separate from the insertion rod.

[0013] The utility model has the following beneficial effects:

[0014] The building curtain wall anti-falling device designed by the utility model can reinforce the curtain wall body stuck on the inner side of the anti-falling frame through design coordination, so as to prevent the curtain wall body from being stuck in the anti-falling frame and shaking due to external force, so that the building curtain wall will be separated from the wall panel. At the same time, the insertion rod is inserted into the slot of the curtain wall body, and the soft film and cone plate at the top end of the front side of the insertion rod can be used to confine the curtain wall body on the inner side of the anti-falling frame, thereby reducing the probability of separation from the anti-falling frame and increasing the stability of the curtain wall body on the inner side of the anti-falling frame.

The front top of the insertion rod 9 is bonded to the soft film 13 by adhesive, and the front end face of the soft film 13 is bonded to the conical plate 14 by adhesive. The rear end face of the extrusion plate 5 contacts the upper and lower sides of the front end face of the curtain wall body 6, the front end face of the buffer sheet 11 contacts the rear end face of the curtain wall body 6, and the rear end face of the soft film 13 contacts the front side of the curtain wall body 6. The curtain wall body 6 stuck on the inside of the anti-falling frame 1 can be reinforced to prevent the curtain wall body 6 from being stuck in the anti-falling frame 1 and shaking due to external force, so that the building curtain wall is separated from the wall panel.

[0022] As a further implementation scheme of the above technical scheme: the number of anti-falling frames 1 is two groups, and the anti-falling frames 1 are distributed on the upper and lower sides of the curtain wall body 6. The inner width of the anti-falling frames 1 is 1.5 times the thickness of the curtain wall body 6, and sufficient space is reserved for the structure of the front end face of the fixing block 7 and the structure inside the threaded limit block 2. Not only are the structures of the front end face of the fixing block 7 and the structure inside the threaded limit block 2 in contact with the curtain wall body 6, but filling material can also be injected into the inner side of the anti-falling frame 1.

[0023] As a further implementation scheme of the above technical scheme: the number of fixing blocks 7 is several, and the fixing blocks 7 are horizontally distributed in the middle of the inner rear of the anti-falling frame 1, and the distance between the fixing blocks 7 is twenty centimeters. Different numbers of fixing blocks 7 can be set according to different lengths of curtain wall bodies 6 to reduce the probability of the curtain wall body 6 falling off from the inner side of the anti-falling frame 1.

[0024] As a further implementation scheme of the above technical scheme: the positions of the slots 10 opened on the upper and lower sides inside the curtain wall body 6 are perpendicular to the position of the fixing block 7, and the diameter of the slots 10 opened inside the curtain wall body 6 matches the cross-sectional diameter of the insertion rod 9, which can fix the curtain wall body 6 inside the anti-falling frame 1 to prevent the curtain wall body 6 from being offset inside the anti-falling frame 1 due to the impact of external force.

[0025] As a further implementation scheme of the above technical scheme: a plurality of threaded limit blocks 2 are fixed on the front side of the anti-falling frame 1, and the distance between the threaded limit blocks 2 is forty centimeters.

When it does not squeeze the curtain wall body 6, it still limits the curtain wall body 6 and is difficult to separate from the insertion rod 9.

[0027] Working principle:

[0028] When using the utility model, the curtain wall body 6 is installed inside the anti-falling frame 1, and the rotating plate 4 is first held and rotated counterclockwise, and the rotating plate 4 drives the threaded rod 3 and the extrusion plate 5 to move toward the front side of the anti-falling frame 1 through the threaded limit block 2, until the front end surface of the extrusion plate 5 contacts the front inside of the anti-falling frame 1, and then the curtain wall body 6 is inserted into the inner side of the anti-falling frame 1 from the top of the left and right sides of the anti-falling frame 1. After the curtain wall body 6 is completely inserted into the anti-falling frame 1, the rotating plate 4 is held and rotated clockwise. At this time, the threaded rod 3 drives the extrusion plate 5 to move toward the front end surface of the curtain wall body 6, until the extrusion plate 5 contacts the front side of the curtain wall body 6, and drives the curtain wall body 6 When moving to the inner rear of the anti-falling frame 1, the curtain wall body 6 will first contact the conical plate 14 at the inner rear of the anti-falling frame 1. When the curtain wall body 6 is forcibly moved backward, the soft film 13 behind the conical plate 14 is deformed, and the slot 10 opened in the curtain wall body 6 is sleeved on the rubber layer 12 outside the insertion rod 9, until the edge of the slot 10 on the rear end face of the curtain wall body 6 contacts the buffer sheet 11 on the front side of the pasting plate 8, the rotation of the rotating plate 4 is stopped. At this time, the curtain wall body 6 is limited by the insertion rod 9 on the front side of the fixed block 7 and cannot be detached. At this time, the operator can inject filling material between the inner side of the anti-falling frame 1 and the curtain wall body 6, and the installation of the curtain wall body 6 is completed.
