It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. Curtain wall is mainly composed of panels and supporting structure system. It has a certain displacement ability relative to the main structure or a certain deformation ability itself. It does not bear the building's external protective structure or decorative structure that the main structure acts on.

[0003] At present, various composite panels are usually used as curtain wall panels in curtain wall systems. For example, the patent document with announcement number CN215406804U discloses a curtain wall for buildings using aluminum honeycomb panels. This type of curtain wall has better sealing, compressive strength, temperature deformation capacity and earthquake resistance, and is more practical. However, after careful analysis by the inventor, it was found that because the curtain wall needs to avoid windows when installed on the building and the facade of the curtain wall often has horizontal aluminum plate shapes and aluminum plate beam shapes, this makes the curtain wall have a more concave and convex shape. When the curtain wall encounters rain, the dust on the surface of the curtain wall will mix with the rainwater, and then pollute the outer surface of the lower end of the curtain wall shape under the action of wind, which affects both the appearance and the use effect.

[0028] Example 1

[0029] like Figure 1 As shown, this embodiment provides an anti-droop hanging part, including an anti-droop strip 1 and a connecting strip 2 for fixing on a curtain wall panel 7. Both the anti-droop strip 1 and the connecting strip 2 can be made of aluminum or plastic, but preferably the same material as the composite board. The cross section of the anti-droop strip 1 and the cross section of the connecting strip 2 are both U-shaped. The anti-droop strip 1 is sleeved on the two side edges of the connecting strip 2 through its two side edges, and a positioning structure is also provided between the anti-droop strip 1 and the connecting strip 2 to prevent the anti-droop strip 1 from sliding on the connecting strip 2.

[0030] According to a preferred implementation of this embodiment, the positioning structure includes positioning convex strips 3 integrally formed on the outer surfaces of both sides of the connecting strip 2 and positioning grooves 4 integrally formed on the inner surfaces of both sides of the anti-droop strip 1. The length of the anti-droop strip 1, the length of the connecting strip 2, the length of the positioning convex strip 3 and the length of the positioning groove 4 are all equal. The positioning convex strip 3 is adapted to the positioning groove 4, and the positioning convex strip 3 is located in the positioning groove 4. In actual application, the anti-droop strip 1 can be inserted into the connecting strip 2 from the end of the connecting strip 2.

[0031] It should be noted that the number of positioning convex strips 3 on each side of the connecting strip 2 and the number of positioning grooves 4 on each side of the anti-droop strip 1 are preferably one. In addition, to prevent the anti-droop strip 1 from sliding on the connecting strip 2, the spacing between the two positioning convex strips 3 is preferably slightly larger than the spacing between the two positioning grooves 4. Since the anti-droop strip 1 and the connecting strip 2 are relatively thin, their two side edges have a certain deformation force, so it is convenient to put the anti-droop strip 1 on the connecting strip 2, and it can also have a better positioning effect.

[0032] According to an optional implementation of this embodiment, the cross-section of the positioning convex strip 3 can be triangular, square or spherical, and correspondingly, the positioning groove 4 is also triangular, square or spherical.

[0033] According to a preferred implementation of this embodiment, Figure 1 As shown, the end surface of the open end of the anti-sagging strip 1 and the outer surface of the bottom edge of the connecting strip 2 are located in the same plane. Therefore, after the anti-sagging hanger is installed on the curtain wall panel 7, the anti-sagging effect of the curtain wall can be effectively improved.

[0034] According to a preferred implementation of this embodiment, Figure 1 As shown, the height of the connecting strip 2 is less than the height of the anti-flow hanging strip 1. Specifically, the height of both sides of the connecting strip 2 is less than the height of both sides of the anti-flow hanging strip 1, so that the two can be reasonably assembled.

[0035] According to a preferred implementation of this embodiment, Figure 1 As shown, a rivet positioning groove 5 is provided in the middle of the bottom edge of the connecting strip 2 along the length direction. In actual use, the connecting strip 2 can be fixed to the curtain wall panel 7 by rivets, and the rivet positioning groove 5 can position the rivet to ensure a better installation effect of the connecting strip 2.

[0036] When the anti-flow hanging part of this embodiment is actually used, the connecting strip 2 can be first fixed to the anti-flow hanging position on the curtain wall panel 7 (such as the bending position of the lower folded edge of the curtain wall panel 7) by rivets, and then the anti-flow hanging strip 1 can be put on the connecting strip 2.

[0037] Example 2

[0038] On the basis of Example 1, Figure 1As shown, in this embodiment, a horizontal extension section 6 is integrally formed on one side of the bottom edge of the anti-flow hanging strip 1. In practical application, the horizontal extension section 6 can prevent rainwater from flowing back along the wind pressure direction, thereby achieving a better protection effect.

[0039] Example 3

[0040] This embodiment provides a curtain wall based on the embodiment 1 or the embodiment 2, such as Figure 2-4 As shown, it includes a curtain wall panel 7 and an anti-flow hanging member, and the anti-flow hanging member is fixed to the upper part and / or the lower folding edge of the curtain wall panel 7 through a connecting strip 2.

[0041] When the anti-flow hanging piece is fixed on the upper part of the curtain wall panel 7, one side edge of the anti-flow hanging strip 1 is in the same plane as the upper folded edge of the curtain wall panel 7, and the other side edge is located below.

[0042] When the anti-flow hanging piece is fixed to the lower folded edge of the curtain wall panel 7, one side edge of the anti-flow hanging strip 1 is in the same plane as the front side of the curtain wall panel 7, and the other side edge is located on the left side.

[0043] Since the end face of the open end of the anti-flow hanging strip 1 and the outer surface of the bottom edge of the connecting strip 2 are located in the same plane, when the anti-flow hanging piece is fixed on the curtain wall panel 7, the side edge of the anti-flow hanging strip 1 will abut against the front face and / or lower folded edge of the curtain wall panel 7.

[0044] The above description is only a specific implementation method of the present utility model. Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes; all disclosed features, or all methods or steps in the process, except for mutually exclusive features and / or steps, can be combined in any way.
