Description

Technical Field

[0001] The invention belongs to the technical field of building curtain walls, and in particular relates to a glass curtain wall structure. Background Art

[0002] With the continuous development of modern building technology, glass curtain walls have become the preferred exterior wall decoration method for many high-rise buildings and large public buildings because of their good lighting, aesthetics and modernity. Glass curtain walls can provide buildings with a wide field of vision, making the interior space more transparent and bright, while also enhancing the overall image and value of the building. However, glass curtain walls face huge challenges when facing wind loads in the natural environment. Wind is a common natural phenomenon, and its effect on buildings is mainly manifested as wind pressure. When strong winds act on glass curtain walls, they will generate greater wind pressure. If the wind resistance of the glass curtain wall is insufficient, it may cause glass breakage, frame deformation, and even damage to the entire curtain wall system, which will seriously affect the safety and appearance of the building. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a glass curtain wall structure, which can effectively improve the wind resistance of a building and increase the safety and life of the building.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] Furthermore, the first connecting assembly includes a first hydraulic cylinder, a limit block, and a limit guide rail. The first hydraulic cylinder is fixed on the back side of a wind-resistant panel. The output end of the first hydraulic cylinder is connected to the limit block. The limit guide rail is fixed on the back side of another wind-resistant panel vertically adjacent to the first hydraulic cylinder. The limit block can cooperate with the limit guide rail for limiting.

[0007] Further, the second connecting assembly includes a second hydraulic cylinder, a slider, a slide rail, a first connecting rod, a second connecting rod, a third connecting rod and a pin shaft. The second hydraulic cylinder is fixed on the back side of a wind-resistant panel. The output end of the second hydraulic cylinder is connected to the slider. The slider is slidably installed on the slide rail. The slider is pivoted to one end of the first connecting rod. The other end of the first connecting rod is pivoted to one end of the third connecting rod through the second connecting rod. The other end of the third connecting rod is pivoted to the pin shaft. The pin shaft is rotatably connected to the back side of another wind-resistant panel laterally adjacent to the second hydraulic cylinder.

[0008] Furthermore, an installation space for installing the first connecting component and the second connecting component is formed between the main panel and the wind-resistant panel.

[0009] Furthermore, the main damping device includes a blade, a damping cylinder and a bracket.

[0012] The beneficial effects of the present invention are:

[0013] A glass curtain wall structure disclosed by the present invention has a wind-resistant panel arranged on the outer side of a main panel. When the wind-resistant panel is affected by wind, the energy can be effectively consumed through a spring damping device and a main damping device, thereby effectively reducing the influence of wind pressure on the main panel, thereby effectively improving the wind resistance of the building and increasing the safety and life of the building.

[0014] In the glass curtain wall disclosed by the present invention, when encountering light wind weather, small wind-resistant panels can be used for damping and energy dissipation. Since the small wind-resistant panels are connected to the main panels through separate spring damping devices, they are more sensitive and can effectively dissipate energy.

[0015] At the same time, by installing a first connecting component and a second connecting component between two adjacent wind-resistant panels, the present invention can combine the wind-resistant panels into a whole when encountering strong winds, and then use the main damping device to consume additional energy, thereby improving the wind-resistant effect of the device and making the safety performance of the glass curtain wall more stable.

[0016] In the glass curtain wall disclosed in the present invention, the use of the main damping device can be achieved through the control of the vertical displacement driving device. When in use, the vertical displacement driving device can control the limiting sleeve and sleeve it on the outside of the rotating column, thereby limiting and consuming energy for the rotation of the overall wind-resistant panel, which not only increases the energy consumption effect of the overall structure, but also improves the stability of the entire device during operation.

[0017] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art may be taught from the practice of the present invention. The objectives and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] like Figures 1 to 5As shown, a glass curtain wall structure disclosed in the present invention comprises a keel frame 1 and a main panel 2 mounted on the keel frame 1. The keel frame 1 is composed of columns and beams. The columns are connected to the building structure through connectors, and the beams are connected to the columns through angle brackets, bolts, etc. The connection method of the columns and the beams should ensure the integrity and stability of the curtain wall, and be able to transmit wind loads, earthquake loads, etc. The glass of the main panel 2 is connected to the keel frame 1 through structural adhesive, double-sided adhesive strips, etc. The structural adhesive has a strong bonding strength and can firmly fix the glass on the keel. The double-sided adhesive strip plays a role of buffering and sealing to prevent the glass from directly contacting the keel to generate stress concentration.

[0026] In the embodiment of the present invention, four wind-resistant panels 3 are installed in a rectangular array on the outside of the main panel 2 in parallel with the main panel 2. Each main panel 2 corresponds to four wind-resistant panels 3. The wind-resistant panels 3 are located on the outside of the main panel 2 and can serve as a decoration. There is a gap between two adjacent wind-resistant panels 3, which can provide space for the wind-resistant panels 3 to make way when rotating to avoid interference. A spring damping device 4 is installed between the wind-resistant panel 3 and the main panel 2. The spring damping device 4 adopts the existing structure, which can provide energy consumption when relative rotation or displacement occurs between the wind-resistant panel 3 and the main panel 2, and can play a role of elastic recovery through the springs connected thereto. When encountering light windy weather, small wind-resistant panels 3 can be used for damping and energy consumption. Since the small wind-resistant panels 3 are connected to the main panel 2 through a separate spring damping device 4, they are more sensitive and can effectively consume energy.

[0027] Those skilled in the art will appreciate that each main panel 2 may correspond to a plurality of wind-resistant panels 3, such as 6, 9 or 16 panels, and the number may be selected according to actual needs.

[0028] Furthermore, in the present invention, a first connection component 5 is connected between two vertically adjacent wind-resistant panels 3, and a second connection component 6 is connected between two horizontally adjacent wind-resistant panels 3; when the first connection component 5 and the second connection component 6 are unloaded, each wind-resistant panel 3 is independent of each other and can be rotated individually to achieve wind-resistant energy consumption. When the first connection component 5 and the second connection component 6 are started, each wind-resistant panel 3 can be connected into a whole, achieving integrated energy consumption, and can cope with greater wind force.

[0029] Among them, the back side of a wind-resistant panel 3 located at the bottom and near the middle is connected to a first semi-cylinder 8 through a first support plate 7, and the back side of another wind-resistant panel 3 adjacent to it is connected to a second semi-cylinder 10 through a second support plate 9, and the two semi-cylinders can be combined to form a rotating column; a limiting sleeve 11 is installed on the main panel 2 corresponding to the rotating column, and the limiting sleeve 11 can be displaced vertically to achieve cooperation or separation with the rotating column. A vertical displacement driving device for controlling the vertical displacement of the limiting sleeve 11 is also installed on the main panel 2; a rotating shaft 12 that can be engaged with the rotating column is rotatably installed in the limiting sleeve 11, and the rotating shaft 12 is connected to the main damping device at one end away from the rotating column. When encountering strong winds, the wind-resistant panels 3 can be combined into a whole. After the vertical displacement driving device drives the limiting sleeve 11, the limiting sleeve 11 can limit the rotating column, and then consume additional energy through the main damping device, thereby improving the wind resistance effect of the device and making the safety performance of the glass curtain wall more stable.

[0030] In this embodiment, the first connecting assembly 5 includes a first hydraulic cylinder 13, a limit block 14, and a limit guide rail 15. The first hydraulic cylinder 13 is fixed on the back side of a wind-resistant panel 3. The output end of the first hydraulic cylinder 13 is connected to the limit block 14. The limit block 14 is in a square shape. The limit guide rail 15 is fixed on the back side of another wind-resistant panel 3 vertically adjacent to the first hydraulic cylinder 13. The limit block 14 can cooperate with the limit guide rail 15 for limiting. When the first hydraulic cylinder 13 is started, the first hydraulic cylinder 13 can drive the limit block 14 to move vertically and cooperate with the limit guide rail 15 to avoid relative rotation between the two vertically adjacent wind-resistant panels 3.

[0031] In some other embodiments, the cooperation between the limit block 14 and the limit guide rail 15 can also adopt a slot and a plug-in connection method, which can connect the two wind-resistant panels 3 together and achieve synchronous displacement.

[0032] In this embodiment, the second connecting assembly 6 includes a second hydraulic cylinder 16, a slider 17, a slide rail 18, a first connecting rod 19, a second connecting rod 20, a third connecting rod 21 and a pin 22. The second hydraulic cylinder 16 is fixed to the back side of a wind-resistant panel 3, and the output end of the second hydraulic cylinder 16 is connected to the slider 17. The driving direction of the second hydraulic cylinder 16 is perpendicular to the driving direction of the first hydraulic cylinder 13. Thus, bidirectional positioning can be achieved.

[0033] The slider 17 is slidably mounted on the slide rail 18, and can be used to guide the slider 17 so that it can be displaced along a straight line. Among them, the slider 17 is pivoted to one end of the first connecting rod 19, and the other end of the first connecting rod 19 is pivoted to one end of the third connecting rod 21 through the second connecting rod 20. The other end of the third connecting rod 21 is pivoted to the pin 22, and the pin 22 is rotatably connected to the back side of another wind-resistant panel 3 that is laterally adjacent to the second hydraulic cylinder 16. When the second hydraulic cylinder 16 is started, the two horizontal wind-resistant panels 3 are relatively fixed. When the second hydraulic cylinder 16 is unloaded, the wind-resistant panels 3 are relatively independent and can independently resist wind energy consumption. In the device of the present invention, by setting the second connecting component 6, it is mainly used to guide the rotation of each wind-resistant panel 3 around its corresponding vertical axis, rather than the horizontal axis, so that the disturbance direction of each wind-resistant panel 3 tends to be consistent, thereby achieving the best energy consumption effect and convenient control.

[0034] In this embodiment, an installation space for installing the first connecting component 5 and the second connecting component 6 is formed between the main panel 2 and the wind-resistant panel 3, which can reduce interference between the device and the main panel 2 or the wind-resistant panel 3.

[0035] In this embodiment, the main damping device includes a blade 23, a damping cylinder 24 and a bracket 25. The upper end sliding seal of the rotating shaft 12 passes through the damping cylinder 24 and is fixedly connected to the blade 23. The blade 23 is rotatably installed in the damping cylinder 24. The damping cylinder 24 is filled with damping fluid. The damping cylinder 24 is installed on the main panel 2 through the bracket 25. When each wind-resistant panel 3 is integrated, the axis of its rotation is the axis of the rotating column. The rotating column drives the blade 23 to rotate through the rotating shaft 12. After the blade 23 stirs the damping fluid, the damping fluid can provide a reverse damping force to the blade 23, thereby realizing the damping energy consumption effect, which can increase the energy consumption effect of the overall panel.

[0036] In this embodiment, a clamping plate 26 is fixed to the lower end of the rotating shaft 12, and a clamping groove 27 cooperating with the clamping plate 26 is provided on the first semi-cylinder 8 and the second semi-cylinder 10. Through the cooperation between the clamping plate 26 and the clamping groove 27, the engagement between the rotating shaft 12 and the rotating column can be facilitated, and the connection and cooperation process is more convenient.

[0037] In this embodiment, the vertical displacement driving device includes a rack 28, a gear 29 and a motor 30, the limiting sleeve 11 is fixedly connected to the rack 28, the rack 28 is meshed with the gear 29, the gear 29 is connected to the motor 30, and the motor 30 is installed on the main panel 2. During specific control, the motor 30 is started, the motor 30 drives the gear 29 to rotate, the gear 29 drives the rack 28 meshed therewith to move, and the rack 28 drives the limiting sleeve 11 to move vertically, so that the limiting sleeve 11 and the rotating shaft 12 can be matched or separated with the rotating column, and the device structure is simple and easy to control.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
