Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a curtain wall expansion joint component. Background Technology

[0002] With the increasing sophistication of architectural design, super-large commercial office projects are emerging, characterized by their large size, high floors, and complex shapes. Due to their enormous size, the main structure requires multiple expansion joints, leading to increasingly complex curtain walls. Architects also have higher and higher requirements for the aesthetic appearance of buildings. Consequently, at the expansion joint locations, architects increasingly desire a consistent effect with the overall facade. Therefore, expansion joints in glass curtain walls have emerged as a necessary solution.

[0003] In the past, expansion joints in glass curtain walls were mostly constructed using metal panels. However, architects now demand greater consistency in material properties and prefer glass panels for these expansion joints. Glass itself is a brittle material with a certain thickness, and the glass in the expansion joint needs to be flush with the main glass surface. Therefore, a component capable of housing the glass within the expansion joint is needed. Utility Model Content

[0029] Example

[0030] Please see Figure 1 as well as Figure 2 This embodiment provides a curtain wall expansion joint assembly, including a left special frame 11, a right special frame 12 and an operable fan 2. The left special frame 11 is fixed to the left side of the expansion joint keel, the right special frame 12 is fixed to the right side of the expansion joint keel, and the operable fan 2 is movably connected to the right special frame 12 via a hinge 21. The operable fan 2 is provided with a decorative panel 3.

[0031] In this embodiment, the curtain wall expansion joint assembly specifically includes three parts: a left-side special frame 11, a right-side special frame 12, and an operable fan 2, which facilitates installation and maintenance by construction personnel. First, the left-side special frame 11 and right-side special frame 12 of the curtain wall expansion joint assembly are fixed to the left and right sides of the expansion joint keel, respectively. Then, the operable fan 2, equipped with the decorative panel 3, is installed on the right-side special frame 12 via hinges 21. This completes the installation of the curtain wall expansion joint assembly, which is convenient, quick, and easy to maintain. When maintenance is required, the operable fan 2 is rotated open to access and maintain the internal structure.

[0032] In a preferred embodiment, a magnetic suction member 13 is provided between the left special-shaped frame 11 and the right special-shaped frame 12, and an opening fan 2 is provided with an opening fan magnetic suction member 22. When the opening fan 2 is closed, the opening fan 2 is attracted to the magnetic suction member 13 through the opening fan magnetic suction member 22.

[0033] In practice, to avoid the influence of airflow on the opening fan, the opening fan 2 needs to be fixed. Considering the convenience of later maintenance, magnetic components 13 are set between the left special frame 11 and the right special frame 12, and opening fan magnetic components 22 are set on the side of the opening fan 2 near the expansion joint keel. The opening fan 2 is magnetically attached to the expansion joint keel, thereby preventing the opening fan 2 from opening and closing under the action of airflow and ensuring the fitting effect of the opening fan.

[0034] As a preferred embodiment, the magnetic attractor 13 is a neodymium iron boron magnet or a samarium cobalt magnet, and the opening fan magnetic attractor 22 is a neodymium iron boron magnet or a samarium cobalt magnet or a ferromagnetic component made of ferromagnetic material.

[0035] In practical implementation, to ensure the magnetic attraction effect between the operable fan 2 and the expansion joint keel, the magnetic component 13 is a neodymium iron boron magnet or a samarium cobalt magnet. Neodymium iron boron magnets or samarium cobalt magnets have extremely high magnetic energy products, enabling them to firmly attract the operable fan 2, thereby preventing the operable fan 2 from opening and closing under the influence of airflow. The operable fan magnetic component 22 is a neodymium iron boron magnet, a samarium cobalt magnet, or a ferromagnetic component made of ferromagnetic material. When the operable fan magnetic component 22 is a neodymium iron boron magnet or a samarium cobalt magnet, the magnetic poles of the operable fan magnetic component 22 are opposite to those of the magnetic component 13. Similarly, the operable fan magnetic component 22 can also be a ferromagnetic component made of ferromagnetic material, such as an iron sheet.

[0036] As a preferred embodiment, a waterproof rubber sheet 14 is provided between the left special frame 11 and the right special frame 12 and the expansion joint keel.

[0037] In practice, waterproof rubber sheeting 14 is installed between the left special frame 11 and the right special frame 12 and the expansion joint keel, which can effectively prevent external moisture from affecting the keel at the expansion joint and ensure the stability and reliability of the overall curtain wall structure.

[0038] For ease of explanation, the definition is... Figure 1 The opening direction of the opening fan is the outer side of the facade, and the closing direction of the opening fan is the inner side of the facade. The two ends of the waterproof rubber sheet 14 are fixed to the left side and the right side of the expansion joint keel by the rubber sheet fastener 15, respectively, and are located inside the left special frame 11 and the right special frame 12.

[0039] In a preferred embodiment, the left special-shaped frame 11 is provided with a left side stop 111 extending to the left of the opening fan 2; the right special-shaped frame 12 is provided with a right side stop 121 extending to the right of the opening fan 2, and the hinge 21 is disposed on the right side stop 121.

[0040] In specific implementation, a left-side baffle 111 extending to the left side of the opening fan 2 is provided on the left-side special frame 11, and a right-side baffle 121 extending to the right side of the opening fan 2 is provided on the right-side special frame 12. Through the left-side baffle 111 and the right-side baffle 121, the force of airflow on the opening fan 2 can be reduced, effectively preventing the opening fan 2 from opening and closing under the action of airflow.

[0041] As a preferred embodiment, the right side stop 121 is provided with a bent portion 122.

[0042] In practice, by providing a bending part 122 on the right side stop 121, the structural strength of the right side stop 121 can be strengthened, enabling it to reliably bear the weight of the opening fan 2.

[0043] In a preferred embodiment, the left side stop 111 is provided with a left side bend 112 extending away from the opening fan 2, and the magnetic member 13 is disposed on the left side bend 112.

[0044] In a specific implementation, by setting a left-side bent portion 112 extending inward toward the direction away from the opening fan 2 on the left side of the stop portion 111, the magnetic suction component 13 is set on the left-side bent portion 112, which is beneficial to the installation of the magnetic suction component 13 and the magnetic attraction effect between the magnetic suction component 13 and the opening fan magnetic suction component 22.

[0045] In a preferred embodiment, the opening fan 2 is provided with a left buffer rubber strip groove corresponding to the left special frame 11, and a left buffer rubber strip 113 is installed in the left buffer rubber strip groove; the opening fan 2 is provided with a right buffer rubber strip groove corresponding to the right special frame 12, and a right buffer rubber strip 123 is installed in the right buffer rubber strip groove.

[0046] In specific implementation, by setting a left buffer rubber strip groove on the side of the opening fan 2 facing the left special frame 11 and installing a left buffer rubber strip 113 in the left buffer rubber strip groove; and setting a right buffer rubber strip groove on the side of the opening fan 2 facing the right special frame 12 and installing a right buffer rubber strip 123 in the right buffer rubber strip groove, it can be ensured that when the opening fan 2 is closed, the opening fan 2 will not make hard contact with the left special frame 11 or the right special frame 12, effectively reducing the risk of the opening fan 2 being damaged by impact.

[0047] Meanwhile, the left buffer strip 113 and the right buffer strip 123 can also provide a certain degree of waterproofing to prevent moisture from invading the inside of the expansion joint.

[0048] As a preferred embodiment, the decorative panel 3 is glass or metal plate.

[0049] In practice, when the facade is made of glass, the decorative panel 3 is also made of glass; when the facade is made of metal, the decorative panel 3 is also made of metal, thus ensuring the consistency of the facade appearance.

[0050] As can be seen from the above description, the beneficial effects of this utility model are as follows: It provides a curtain wall expansion joint component with a reasonable structure, convenient installation, and reliable construction. Through this component, decorative panels of the same material as the exterior facade can be installed at the curtain wall expansion joint, making the overall consistency of the curtain wall better and more beautiful.

[0051] It will be readily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

[0052] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
