[0029] Example

[0030] See also Figure 1 as well as Figure 2 The present embodiment provides a curtain wall expansion joint assembly, including a left special-shaped frame 11, a right special-shaped frame 12 and an opening fan 2, wherein the left special-shaped frame 11 is fixed to the left side of the expansion joint keel, the right special-shaped frame 12 is fixed to the right side of the expansion joint keel, the opening fan 2 is movably connected to the right special-shaped frame 12 through a hinge 21, and the opening 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 special-shaped frame 11, a right special-shaped frame 12, and an opening fan 2, which can facilitate the installation and maintenance work of construction personnel. First, the left special-shaped frame 11 and the right special-shaped frame 12 of the curtain wall expansion joint assembly are fixed to the left and right sides of the expansion joint keel respectively, and then the opening fan 2 with the decorative panel 3 installed is installed on the right special-shaped frame 12 through the hinge 21, and the installation of the curtain wall expansion joint assembly can be completed. It is convenient and fast, and easy to maintain. When maintenance is required, the opening fan 2 is rotated to open, and the internal structure can be maintained.

[0032] As a preferred embodiment of the present invention, a magnetic component 13 is provided between the left special frame 11 and the right special frame 12, and the opening fan 2 is correspondingly provided with an opening fan magnetic component 22. When the opening fan 2 is closed, the opening fan 2 is adsorbed on the magnetic component 13 through the opening fan magnetic component 22.

[0033] During specific implementation, in order to avoid the influence of airflow on the opening fan, the opening fan 2 needs to be fixed. Considering the convenience of later maintenance, a magnetic suction part 13 is respectively arranged between the left special frame 11 and the right special frame 12, and an opening fan magnetic suction part 22 is correspondingly arranged on the side of the opening fan 2 close to the expansion joint keel, so that the opening fan 2 can be magnetically adsorbed to the expansion joint keel, thereby avoiding the opening and closing action of the opening fan 2 under the action of airflow, thereby ensuring the fitting effect of the opening fan.

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

[0035] During specific implementation, in order to ensure the magnetic adsorption effect between the opening fan 2 and the expansion joint keel, the magnetic attraction member 13 is a neodymium iron boron magnet or a samarium cobalt magnet. The neodymium iron boron magnet or the samarium cobalt magnet has an extremely high magnetic energy product, which can firmly adsorb the opening fan 2, thereby preventing the opening fan 2 from opening and closing under the action of the airflow. The opening fan magnetic attraction member 22 is a ferromagnetic member made of a neodymium iron boron magnet or a samarium cobalt magnet or a ferromagnetic material. When the opening fan magnetic attraction member 22 is a neodymium iron boron magnet or a samarium cobalt magnet, the magnetic pole of the opening fan magnetic attraction member 22 is opposite to the magnetic pole of the magnetic attraction member 13. Similarly, the opening fan magnetic attraction member 22 can also be a ferromagnetic member made of a ferromagnetic material, such as an iron sheet.

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

[0037] In specific implementation, a waterproof rubber 14 is provided between the left special-shaped frame 11 and the right special-shaped frame 12 and the expansion joint keel, which can effectively prevent external water vapor from affecting the keel at the expansion joint and ensure the stability and reliability of the overall structure of the curtain wall.

[0038] For the convenience of explanation, we define Figure 1 The opening direction of the opening fan is the outside of the facade, and the closing direction of the opening fan is the inside of the facade. The two ends of the waterproof rubber 14 are respectively fixed to the left side and the right side of the expansion joint keel by rubber fixing parts 15, and are located on the inner side of the left special frame 11 and the right special frame 12.

[0039] As a preferred embodiment of this embodiment, the left special frame 11 is provided with a left stopper 111 extending to the left side of the opening fan 2; the right special frame 12 is provided with a right stopper 121 extending to the right side of the opening fan 2, and the hinge 21 is arranged on the right stopper 121.

[0040] In a specific implementation, a left-side blocking portion 111 extending toward the left side of the opening fan 2 is provided on the left-side special frame 11, and a right-side blocking portion 121 extending toward the right side of the opening fan 2 is provided on the right-side special frame 12. The left-side blocking portion 111 and the right-side blocking portion 121 can reduce the force of the airflow on the opening fan 2, thereby effectively preventing the opening fan 2 from opening and closing under the action of the airflow.

[0041] As a preference of this embodiment, the right side stop portion 121 is provided with a bending portion 122 .

[0042] In a specific implementation, by providing a bending portion 122 on the right side stop portion 121 , the structural strength of the right side stop portion 121 can be enhanced so that the right side stop portion 121 can reliably bear the weight of the opening sash 2 .

[0043] As a preference of this embodiment, the left side blocking portion 111 is provided with a left side bending portion 112 extending in a direction away from the opening fan 2 , and the magnetic attraction member 13 is arranged on the left side bending portion 112 .

[0044] In specific implementation, by setting a left side bending portion 112 on the left side blocking portion 111 that extends away from the opening fan 2, that is, inward, the magnetic attraction component 13 is set on the left side bending portion 112, which is beneficial to the installation of the magnetic attraction component 13 and the magnetic attraction effect between the magnetic attraction component 13 and the opening fan magnetic attraction component 22.

[0045] As a preferred embodiment of the present invention, 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, a left buffer rubber strip groove is set on the side of the opening fan 2 facing the left special frame 11, and the left buffer rubber strip 113 is installed in the left buffer rubber strip groove; a right buffer rubber strip groove is set on the side of the opening fan 2 facing the right special frame 12, and the right buffer rubber strip 123 is installed in the right buffer rubber strip groove, so that when the opening and closing fan 2 is closed, the opening and closing fan 2 will not have hard contact with the left special frame 11 or the right special frame 12, thereby effectively reducing the risk of the opening fan 2 being damaged.

[0047] At the same time, the left buffer rubber strip 113 and the right buffer rubber strip 123 can also provide a certain waterproof performance to prevent water vapor from invading the inner side of the expansion joint.

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

[0049] In specific implementation, when the exterior facade is glass, the decorative panel 3 is also glass; when the exterior facade is a metal plate, the decorative panel 3 is also a metal plate, thereby ensuring the consistency of the exterior facade appearance.

[0050] From the above description, it can be seen that the beneficial effects of the present invention are: providing a curtain wall expansion joint assembly, which has a reasonable structure, is easy to install, and has a reliable construction. Through this assembly, decorative panels of the same material as the facade can be installed at the curtain wall expansion joint, making the overall consistency of the curtain wall better and more beautiful.

[0051] It is easy for those skilled in the art to understand that the above-mentioned implementation modes can be freely combined and superimposed without conflict.

[0052] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
