Description

Technical Field

[0001] This utility model belongs to the technical field of fireproof curtain wall structural components, specifically relating to a novel fireproof curtain wall corner bracket structural component. Background Technology

[0002] In existing fireproof curtain wall structures, in order to achieve structural strength, corner brackets (also known as connectors) must be used to fasten the longitudinal and transverse keels together. After fastening, a layer of metal decorative panel is wrapped around the fastening connection to cover the connection for decorative purposes.

[0003] While the above methods achieve a secure connection, no exposed fasteners, and an aesthetically pleasing appearance, they require a larger quantity of profiles, increasing unnecessary costs. Furthermore, the corner bracket structure has a complex shape, making processing inconvenient, and leaves noticeable exposed areas after installation, necessitating additional decorative panels for concealment, further increasing costs.

[0004] Secondly, real-world curtain wall structures are not always flat. Some building facades have undulating shapes, such as externally curved or internally curved curtain walls. Specifically, the longitudinal keel structure in the curtain wall remains unchanged, while the connecting ends of the transverse keels need to be cut at a certain angle to adapt to the undulating angles of the curtain wall facade. However, transverse keels with cut ends at a certain angle cannot be used with existing corner bracket structural components.

[0005] Moreover, the cutting positions of the horizontal keel ends are completely different for this undulating curtain wall, and the structural requirements of the corner bracket components are diverse. Therefore, the corner bracket components currently in use need further improvement and upgrading. Thus, it is necessary to design a corner bracket component with a simpler and easier-to-use structure.

[0006] Utility model patent CN223034285U discloses a corner bracket structural component applicable to flat curtain walls, externally curved curtain walls, and internally curved curtain walls. However, it still has certain drawbacks in practical application, such as limited firmness between the connecting block body and the positioning part, which affects the overall support strength. Utility Model Content

[0007] In order to solve the above-mentioned technical problems, this utility model provides a new type of fireproof curtain wall corner bracket structure, which can further improve the existing connector structure and enhance the overall support strength.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A novel fireproof curtain wall corner bracket structural component, including a connecting block body;

[0010] One side of the connecting block body is provided with an outwardly extending support structure. The support structure includes a positioning part 1 located near both ends of the side of the connecting block body, and a positioning part 2 spaced between the two positioning parts 1. The positioning part 2 is provided with a side support extending toward the outdoor side, and a connecting part is provided on the side of the side support away from the positioning part 2.

[0011] The connection between the connecting block body and the positioning part two is also provided with a protrusion, and the protrusion protrudes towards the outdoor side.

[0012] Furthermore, the supporting structure is inclined towards the outdoor side or towards the indoor side.

[0013] Furthermore, the connecting block body is provided with at least one positioning hole that extends through the longitudinal keel direction.

[0014] Furthermore, the two positioning parts are symmetrical to each other.

[0015] Furthermore, the extension length of the second positioning part is longer than the extension length of the first positioning part.

[0016] Furthermore, the protrusion is provided with at least one fixing hole that extends through the longitudinal keel direction.

[0017] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:

[0018] The protrusions can significantly improve the rigidity of the connection, thereby increasing the overall support strength.

[0019] The support structure in this invention is an inclined structure, meaning there is a certain angle between the support structure and the connecting block body. This angle is the connection angle between the transverse keel and the longitudinal keel, which can firmly fix the transverse keel to the longitudinal keel. The second positioning part can be fitted into the convex inner cavity of the transverse keel for positioning. Then, fasteners such as screws or rivets are used to pass through the convex part of the transverse keel and connect and tighten with the second positioning part, achieving a stable connection effect.

[0045] Example 1

[0046] See attached document Figure 1 To be continued Figure 5 This embodiment uses the inner arc structure of the curtain wall as an example for illustration.

[0047] This utility model provides a novel fireproof curtain wall corner bracket structural component, including a connecting block body 100, which is used to fit with the longitudinal keel 300, specifically, it is fitted to the outdoor side of the longitudinal keel 300 (see reference). Figure 4 and Figure 5The connecting block body 100 is provided with at least one positioning hole 101 extending towards the longitudinal keel 300. Fasteners such as screws or rivets can be used to fasten the connecting block body 100 to the longitudinal keel 300 through the positioning hole 101. In actual use, 2-3 positioning holes 101 are usually provided, and they are staggered to correspond to each other, which can achieve a better stable connection effect.

[0048] One side of the connecting block body 100 is provided with an outwardly extending support structure, which is integrally formed with the connecting block body 100. This support structure is used to connect with the horizontal keel 400. Moreover, the support structure is inclined towards the outdoor side, and the angle of inclination needs to be consistent with the cutting angle of the end face of the horizontal keel 400, that is, consistent with the undulation angle of the curtain wall facade. Only in this way can the support structure be inserted into the inner cavity of the horizontal keel 400 to achieve a perfect fit and connection between the two.

[0049] The support structure includes positioning portions 201 located near both ends of the side of the connecting block body 100, and positioning portions 202 spaced apart between the two positioning portions 201. Both positioning portions 201 and positioning portions 202 extend and tilt in the same direction (see reference). Figures 1 to 3 The reason why positioning component 1 201 and positioning component 2 202 are spaced apart is to ensure that the thickness of the profile at the insertion end of the transverse keel 400 can be perfectly fitted into this gap for a proper insertion (see reference). Figure 4 and Figure 5 Positioning component 201 is used to provide height-limiting support for the transverse keel 400. Furthermore, positioning component 202 is inserted into the protruding inner cavity of the transverse keel 400 and also serves as a limiting support along with positioning component 201.

[0050] The positioning part 202 is provided with a side support part 203 extending towards the outside. A connecting part 204 is provided on the side of the side support part 203 away from the positioning part 202. The side support part 203 extends towards the outside to fit snugly against the protruding inner cavity of the transverse keel 400, improving the limiting and supporting effect. Furthermore, the connecting part 204 can also be used to connect with fasteners such as screws or rivets. That is, by inserting a screw or rivet through the protruding part of the transverse keel 400 from the outside direction and then through the connecting part 204, a fixed connection with the transverse keel 400 can be achieved.

[0051] Of course, when fasteners such as screws or rivets are tightened on the exterior side, retaining strips are also installed to securely fix the glass to the horizontal and vertical keels. Finally, decorative panels are used for fastening, so that there are no exposed screws or rivets on the exterior surface, resulting in a neat and aesthetically pleasing appearance. On the interior side of the horizontal keel 400, fasteners 500 are used to securely connect it to the vertical keel 300, thus firmly fixing the horizontal keel to the vertical keel.

[0052] As a further improvement to this embodiment, the two positioning parts 201 are symmetrically arranged, making them more aesthetically pleasing and neat.

[0053] Furthermore, the extension length of the second positioning part 202 is longer than that of the first positioning part 201, allowing the second positioning part 202 to be inserted deeper into the inner cavity of the transverse keel 400, thus providing better limiting and support. The first positioning part 201, being shorter, serves to externally limit and support the transverse keel 400, preventing displacement of the transverse keel 400 in the height direction.

[0054] The connection between the connecting block body 100 and the positioning part 202 is further provided with a protrusion 600, which protrudes towards the outdoor side. The protrusion 600 significantly improves the support strength at the connection, thereby increasing the overall support strength, whereas traditional structures offer limited support at the connection. Fixing holes 601 can also be provided on the protrusion 600, allowing for a more secure connection to the longitudinal keel using bolts or screws.

[0055] Example 2

[0056] See attached document Figure 6 To be continued Figure 10 This embodiment uses the outer arc structure of the curtain wall as an example for illustration.

[0057] The similarities between this embodiment and Embodiment 1 will not be repeated here.

[0058] In this embodiment, the supporting structure is tilted towards the interior side, and the angle of tilt needs to be consistent with the cutting angle of the end face of the horizontal keel 400, that is, consistent with the undulation angle of the curtain wall's exterior facade. This is so that the supporting structure can be inserted into the inner cavity of the horizontal keel 400, achieving a perfect fit and connection between the two. As for the longitudinal keel 300, it is not modified and remains in its common vertical position. With the horizontal keel 400 tilted towards the interior side, the exterior facade of the curtain wall becomes an outwardly curved undulating structure.

[0059] Example 3

[0060] See attached document Figure 11 To be continued Figure 15 This embodiment uses a flat exterior facade of the curtain wall as an example for illustration.

[0061] The similarities between this embodiment and Embodiment 1 will not be repeated here.

[0062] In this embodiment, the supporting structure is not tilted towards the indoor or outdoor side. That is to say, both positioning part 1 201 and positioning part 2 202 are on the same plane as the connecting block body 100, and the corresponding horizontal and vertical keels are also connected on the same plane, so the exterior facade of the curtain wall has a flat surface.

[0063] Explanation of the principle:

[0064] In an inward-curved curtain wall structure, a cut at a certain angle is required at the outdoor side of the horizontal keel 400 connection end. This causes the horizontal keel 400 to shift towards the outdoor side, resulting in an inward-curved undulating structure on the exterior facade of the curtain wall (see reference). Figure 4 and Figure 5 ).

[0065] In an externally curved curtain wall structure, a cut at a certain angle is required at the indoor side of the horizontal keel 400 connection end. This causes the horizontal keel 400 to shift towards the indoor side, resulting in an externally curved, undulating facade of the curtain wall (see reference). Figure 9 and Figure 10 ).

[0066] In a curtain wall structure with a flat exterior, the ends of the 400mm horizontal keel are flat right-angle cuts, allowing for right-angle connections with the vertical keel, thus creating a flat, planar exterior (see reference). Figure 14 and Figure 15 ).

[0067] The tilt angle of the supporting structure can be modified according to actual needs, such as the common 45-degree or 135-degree angles. That is, the curvature angle of the curtain wall's exterior needs to correspond to the tilt angle of the supporting structure. Compared to traditional connectors, the convex connector of this invention is significantly simplified, smaller in size, and easier to use, especially in installation, where workers only need to perform simple plug-in and tightening operations. Furthermore, to adapt to the varying angles of the curtain wall's undulating structure, the angle processing of the convex connector is also simpler, resulting in lower production costs.

[0068] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
