Description

Technical Field

[0001] This utility model relates to the field of aluminum panel curtain wall technology, and in particular to a close-fitting aluminum panel curtain wall system. Background Technology

[0002] Aluminum panel curtain walls offer a unique texture, rich and lasting colors, diverse shapes, and are compatible with stone curtain wall materials. Compared to stone and glass curtain walls, they are significantly lighter, weighing only one-fifth that of marble and one-third that of glass curtain walls, greatly reducing the load on the building structure. However, the installation of aluminum panel curtain walls requires sequential connection of a frame, connectors, and embedded parts onto the wall surface. The lack of locking and securing between adjacent aluminum panels results in a less secure installation.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a close-fitting aluminum panel curtain wall system to enhance the overall installation strength of the aluminum panel curtain wall.

[0005] The technical solution of this utility model is as follows:

[0006] The close-fitting aluminum panel curtain wall system includes:

[0007] The keel is installed on the main body of the building;

[0008] The connector includes a female sub-frame and a male sub-frame disposed on the keel; the female sub-frame is connected to the keel; a slot is provided on the side of the female sub-frame near the male sub-frame; the male sub-frame extends into the slot.

[0009] An aluminum panel is mounted on the connector; the edge of the aluminum panel is bent toward the keel to form a folded edge.

[0010] In this configuration, the opposite sides of one of the aluminum panels are respectively connected to the female sub-frame and the male sub-frame on the adjacent keel; the folded edge extends into the gap between the female sub-frame and the male sub-frame and connects to either the female sub-frame or the male sub-frame.

[0011] A further technical solution is that a countersunk hole is provided on the folded edge and a threaded fastener is provided; the threaded fastener passes through the aluminum panel along the countersunk hole and is screwed into the female sub-frame or the male sub-frame.

[0012] A further technical solution is that bolts are also provided on the plane of the aluminum panel parallel to the keel; the bolts connect the female sub-frame or the male sub-frame.

[0013] A further technical solution is that the bolts are disposed on the surface near the keel; the bolts are welded to the aluminum panel.

[0014] A further technical solution is that the female sub-frame and the male sub-frame have protrusions extending from their surfaces that contact the bolt; the protrusions contact the aluminum panel, thereby forming cavities between the female sub-frame and the aluminum panel, and between the male sub-frame and the aluminum panel; the bolt passes through the cavity.

[0015] A further technical solution is that the end of the female sub-frame or male sub-frame away from the folded edge is bent and positioned towards the keel.

[0016] A further technical solution is to provide a glue-applying groove on the edge of the female sub-frame and the male sub-frame that contacts the aluminum panel, away from the folded edge; structural adhesive is provided in the glue-applying groove to connect the aluminum panel.

[0017] A further technical solution is that an elastic pad is provided between the male and female sub-frames in the slot; an elastic pad is also provided between adjacent aluminum panels.

[0018] A further technical solution is that a gasket is provided between the female sub-frame and the keel; the female sub-frame is connected to the keel by fixing screws.

[0019] A further technical solution is that a waterproof membrane is also laid on the keel; the female sub-frame and the male sub-frame are set on the waterproof membrane.

[0020] The beneficial technical effects of this utility model are as follows:

[0021] (1) In the close-fitting aluminum panel curtain wall system of this utility model, the aluminum panels are fixed to the keel by a female sub-frame and a male sub-frame, and a slot is opened on the side of the female sub-frame near the male sub-frame, into which the male sub-frame extends to connect with the female sub-frame. The connection between the male and female sub-frames indirectly fixes the adjacent aluminum panels. When the close-fitting aluminum panel curtain wall system is subjected to stress perpendicular to the keel, the stress can be transferred between the adjacent female and male sub-frames, thereby improving the overall structural strength of the close-fitting aluminum panel curtain wall system. In addition, the edge of the aluminum panel is bent towards the keel to form a folded edge, which extends into the gap between the female and male sub-frames and connects to the female or male sub-frame, hiding the connection marks between the aluminum panel and the female or male sub-frames, thereby improving the aesthetics of the entire close-fitting aluminum panel curtain wall system.

[0022] (2) Furthermore, countersunk holes are provided on the folded edge. Threaded fasteners pass through the countersunk holes into the aluminum panel and connect to the female or male sub-frame. The threaded fasteners will not protrude after being screwed into the countersunk holes, avoiding interference between the aluminum panels. At the same time, concealing the threaded fasteners further enhances the aesthetics of the entire close-fitting aluminum panel curtain wall system.

[0023] (3) Furthermore, bolted female or male sub-frames are also provided on the plane of the aluminum panel parallel to the keel. The bolts and threaded fasteners work together to fix the aluminum panel on the female or male sub-frames, improving the fixing strength of the aluminum panel. Attached Figure Description

[0029] Figure 1A cross-sectional structural diagram of a close-fitting aluminum panel curtain wall system according to an embodiment of this disclosure is shown. Please refer to... Figure 1 The close-fitting aluminum panel curtain wall system includes a keel 1, which is installed on the main building structure. Multiple keels 1 are combined horizontally and vertically to form an overall frame component system. Connectors include a female sub-frame 4 and a male sub-frame 5 installed on the keel 1. The female sub-frame 4 connects to the keel 1. A slot 43 is provided on the side of the female sub-frame 4 near the male sub-frame 5. The male sub-frame 5 extends into the slot 43 and connects to the female sub-frame 4. The connection between the male sub-frame 5 and the female sub-frame 4 indirectly fixes the adjacent aluminum panels 3. When the close-fitting aluminum panel curtain wall system is subjected to stress perpendicular to the keel 1, this stress can be transferred between the adjacent female sub-frames 4 and male sub-frames 5, thereby improving the overall structural strength of the close-fitting aluminum panel curtain wall system. The aluminum panels 3 are installed on the connectors. The edges of the aluminum panels 3 are bent towards the keel 1 to form a folded edge 31.

[0030] In this system, one aluminum panel 3 is connected to a female sub-frame 4 and a male sub-frame 5 on the opposite side of an adjacent keel 1. A folded edge 31 extends into the gap between the female sub-frame 4 and the male sub-frame 5, and connects to either the female sub-frame 4 or the male sub-frame 5. This connection conceals the connection marks between the aluminum panel 3 and the female / male sub-frames 4 and 5, thereby enhancing the aesthetics of the entire close-fitting aluminum panel curtain wall system.

[0031] Bolts 32 are also provided on the plane of the aluminum panel 3 parallel to the keel 1. Bolts 32 connect to the female sub-frame 4 or the male sub-frame 5. Bolts 32 and threaded fasteners 312 work together to fix the aluminum panel 3 to the female sub-frame 4 or the male sub-frame 5, thereby improving the fixing strength of the aluminum panel 3.

[0032] Preferably, the bolts 32 are located on the surface near the keel 1. The bolts 32 are welded to the aluminum panel 3 without penetrating it, ensuring the parallelism and aesthetics of the exterior of the aluminum panel 3.

[0033] More preferably, protrusions 45 extend from the surfaces of the female sub-frame 4 and the male sub-frame 5 that contact the bolt 32. The protrusions 45 contact the aluminum panel 3, forming cavities 46 between the female sub-frame 4 and the aluminum panel 3, and between the male sub-frame 5 and the aluminum panel 3. The bolt 32 passes through the cavity 46. When the aluminum panel 3 is subjected to vibration or impact, the gap can reduce stress-induced fluctuations, extending the service life of the bolt 32.

[0034] A countersunk hole 311 is provided on the folded edge 31, and a threaded fastener 312 is installed. The threaded fastener 312 passes through the aluminum panel 3 through the countersunk hole 311 and is screwed into the female sub-frame 4 or male sub-frame 5. After the threaded fastener 312 is screwed into the countersunk hole 311, it will not protrude 45, avoiding interference between the threaded fastener 312 and the splicing between the aluminum panels 3. At the same time, hiding the threaded fastener 312 further enhances the aesthetics of the entire close-fitting aluminum panel curtain wall system.

[0035] Preferably, the end of the female sub-frame 4 or male sub-frame 5 away from the folded edge 31 is bent and positioned towards the keel 1. This supports the aluminum panel 3 on the keel 1 and improves the compressive strength of the aluminum panel 3.

[0036] More preferably, a gasket 41 is provided between the sub-frame 4 and the keel 1. The sub-frame 4 is connected to the keel 1 by a fixing screw 42. The gasket 41 can fill the gap formed by unevenness between the sub-frame 4 and the keel 1, increase the contact area between the sub-frame 4 and the keel 1, disperse stress, and thus improve the connection stability between the sub-frame 4 and the keel 1.

[0037] On the side away from the folded edge 31, the female sub-frame 4 and male sub-frame 5 are provided with a glue groove 44 at the edge of the aluminum panel 3. Structural adhesive 6 is provided in the glue groove 44 to connect the aluminum panel 3, thereby improving the stability of the connection between the aluminum panel 3 and the female sub-frame 4 and male sub-frame 5.

[0038] Preferably, an elastic pad 7 is provided between the male sub-frame 5 and the female sub-frame 4 within the slot 43, and an elastic pad 7 is also provided between adjacent aluminum panels 3. The elastic pad 7 can be made of EPDM rubber to absorb the vibration energy of the closely spaced aluminum panel curtain wall system when it is impacted. At the same time, the elastic pad 7 can fill the gaps and improve the sealing performance.

[0039] More preferably, a waterproof membrane 2 is also laid on the keel 1. The female sub-frame 4 and the male sub-frame 5 are set on the waterproof membrane 2. The waterproof membrane 2 isolates rainwater from the keel 1, preventing the keel 1 from being contaminated by rainwater and corroded, thereby extending the service life of the keel 1.

[0040] The specific installation process of this utility model is as follows:

[0041] Multiple keel beams 1 are pre-embedded horizontally and vertically on the main building structure to form an overall frame component system. Aluminum panels 3, female sub-frames 4, and male sub-frames 5 are pre-assembled. Bolts 32 on aluminum panels 3 pass through female sub-frames 4 and are threaded to nuts (not shown in the figure), and bolts 32 on aluminum panels 3 pass through male sub-frames 5 and are threaded to nuts (not shown in the figure). Threaded fasteners 312 pass through countersunk holes 311 through flanges 31, connecting flanges 31 and female sub-frames 4, and connecting flanges 31 and male sub-frames 5. Then, the assembled aluminum panels 3, female sub-frames 4, and male sub-frames 5 are moved to the preset installation positions on-site, and the female sub-frames 4 are fixed to the keel beams 1 using fixing screws 42. The male sub-frames 5 are inserted into the slots 43 on the adjacent female sub-frames 4. The above installation actions for aluminum panels 3 are repeated until all aluminum panels 3 are installed.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
