Description

Technical Field

[0001] The present application relates to the technical field of building engineering, and in particular to an integrated wind-resistant structure of an eaves curtain wall. Background Art

[0002] The curtain wall is the exterior wall of a building. It is a lightweight panel with decorative effects commonly used in modern large and high-rise buildings. Since the curtain wall is usually not load-bearing, a wind-resistant structure is usually set behind the curtain wall.

[0003] In the prior art, the wind-resistant structure is often separated from the steel structure system of the roof. Therefore, when the facade curtain wall is laid on the outside of the wind-resistant structure, there is a certain gap between the eaves and the roof of the facade curtain wall, which affects the beauty of the building. However, when the wind-resistant structure is separated from the steel structure system of the roof, if the eaves and the facade curtain wall are directly integrated and seamlessly designed, under the action of gravity load, wind load and temperature stress, it is easy to cause the facade curtain wall to deform greatly at the intersection with the eaves, which is generally difficult for the curtain wall panels to withstand, and there is a risk of serious deformation or tearing.

[0004] In summary, since the wind-resistant curtain wall structure in the prior art faces the problems mentioned above, how to propose a better wind-resistant curtain wall structure is a problem that needs to be solved urgently in the art. Summary of the invention

[0005] In view of this, the present invention provides a curtain wall wind-resistant structure, which can realize the seamless design of the building eaves and the facade curtain wall, and ensure the seamless appearance requirements and stress safety of the eaves and the facade curtain wall.

[0006] The technical solution of the present invention is specifically achieved as follows:

[0007] A curtain wall wind-resistant structure comprises: a plurality of frame units, a pin support, a sliding support and a fixed support;

[0008] The plurality of frame units include: a top frame unit, at least one middle frame unit and a bottom frame unit; wherein,

[0009] The top end of the top frame unit is connected to the roof steel structure through a pin support, and the bottom end is connected to the preset beam body through a sliding support;

[0010] The middle frame units are sequentially arranged directly below the top frame units, and the top end of each middle frame unit is connected to the preset beam body corresponding to the top end thereof through a fixed support, and the bottom end thereof is connected to the preset beam body corresponding to the bottom end thereof through a sliding support;

[0011] The bottom frame unit is arranged directly below the middle frame unit, the top end of which is connected to the corresponding preset beam body through a fixed support, and the bottom end of which is connected to the ground through a sliding support;

[0012] An expansion joint is arranged between every two adjacent frame units.

[0013] Preferably, each frame unit comprises: two plane frames, connecting web members and diagonal web members;

[0014] The two planar frames are arranged correspondingly in front and back, and the four corners of the two planar frames are connected correspondingly through connecting web members. A plurality of diagonal web members are connected between the sides of the two planar frames, and the connecting web members, the diagonal web members and the planar frames form a spatial truss structure.

[0015] Preferably, at least one horizontal rod and at least one vertical rod are also arranged inside each planar frame.

[0016] Preferably, an oblique rod is provided between the horizontal rod and the vertical rod.

[0017] Preferably, a horizontal web bar is provided between the two upper planar frames of the top frame unit.

[0018] Preferably, the upper portion of the front planar frame of the top frame unit is bent forward at a preset angle to form a receiving portion.

[0019] As can be seen above, in a curtain wall wind-resistant structure of the present invention, by connecting the top of the wind-resistant structure with the roof steel structure as one, the facade curtain wall and the eaves laid on the outer surface of the wind-resistant structure can also be designed as an integrated seamless design, thereby ensuring the beauty of the building. Since the wind-resistant structure is directly connected to the roof steel structure, it can also play a better load-bearing role on the facade curtain wall at the junction with the eaves, preventing the curtain wall there from being severely deformed or torn. By providing a pin support and a sliding support, and providing an expansion joint between the frame units, the wind-resistant structure and the facade curtain wall can be deformed in coordination, so that a large deadweight and temperature deformation will not accumulate at the bottom of the wind-resistant structure, eliminating the risk of the facade curtain wall being torn under the action of load and temperature, and ensuring the appearance requirements and force safety of the seamless connection between the eaves and the facade curtain wall. Furthermore, by setting the wind-resistant structure in sections, only the top frame unit is suspended and connected under the roof steel structure, which reduces the load on the roof steel structure and is more conducive to the realization of a lightweight shape of the roof steel structure. In addition, the dead weight of each frame unit is small, making construction easier. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1 and Figure 2 As shown, the present invention provides a curtain wall wind-resistant structure, comprising: a plurality of frame units 1, a pin support 3, a sliding support 4 and a fixed support 5;

[0024] The plurality of frame units 1 include: a top frame unit 1-1, at least one middle frame unit 1-2 and a bottom frame unit 1-3; wherein,

[0025] The top end of the top frame unit 1-1 is connected to the roof steel structure 100 through a pin support 3, and the bottom end thereof is connected to a preset beam body through a sliding support;

[0026] The middle frame units 1-2 are sequentially arranged directly below the top frame unit 1-1, and the top end of each middle frame unit 1-2 is connected to the corresponding preset beam body at the top end through a fixed support 5, and the bottom end thereof is connected to the corresponding preset beam body at the bottom end through a sliding support 4;

[0027] The bottom frame unit 1-3 is arranged directly below the middle frame unit 1-2, and its top end is connected to the corresponding preset beam body through a fixed support 5, and its bottom end is connected to the ground through a sliding support 4;

[0028] An expansion joint 2 is provided between every two adjacent frame units 1 .

[0029] In the technical solution of the present invention, the top frame unit 1-1 is connected to the roof steel structure 100 by using the pin support 3, and it is no longer separated from the setting, so that the facade curtain wall and the eaves laid on the outer surface of the wind-resistant structure can be seamlessly designed (for example, the facade curtain wall is laid on the outer surface of the wind-resistant structure). Figure 2 The left side of the wind-resistant structure in the structure is closely fitted with the cornice 101 without a certain gap, which ensures the beauty of the building. Since the wind-resistant structure is directly connected to the roof steel structure 100, it can also play a better load-bearing role on the facade curtain wall at the junction with the cornice, preventing the curtain wall at this location from being seriously deformed or torn. In addition, since the pin support 3 has one degree of rotation freedom (for example, Figure 1 The top frame unit 1-1 in the figure can realize a small rotation perpendicular to the paper surface along the pin support 3 at its top end), and the sliding support 4 set at the bottom end of each frame unit 1 can also provide a sliding freedom (for example, Figure 1The bottom ends of the frame units 1 in the structure can all use the sliding support 4 to achieve a slight left-right slide). Therefore, when there is a wind load, the pin support 3 and the sliding support 4 can be used to coordinate the deformation between the wind-resistant structure and the facade curtain wall, thereby protecting the facade curtain wall laid on the outer side of the wind-resistant structure and preventing damage to the facade curtain wall. Furthermore, by setting a plurality of frame units 1 and setting expansion joints 2 between each frame unit 1, a segmented setting is achieved, so that a large deadweight and temperature deformation will not accumulate at the bottom of the wind-resistant structure, eliminating the risk of the facade curtain wall being torn under the action of load and temperature, and ensuring the appearance requirements and force safety of the seamless connection between the eaves and the facade curtain wall.

[0030] In the technical solution of the present invention, a variety of implementation methods can be used to implement the above-mentioned curtain wall wind-resistant structure. The technical solution of the present invention will be described in detail below by taking one of the implementation methods as an example.

[0031] For example, preferably, in a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, each frame unit 1 may include: two planar frames 11, connecting web members 15 and diagonal web members 17;

[0032] The two planar frames 11 are arranged correspondingly in front and back, and the four corners of the two planar frames 11 are connected correspondingly through connecting web members 15. A plurality of diagonal web members 17 are connected between the sides of the two planar frames 11. The connecting web members 15, the diagonal web members 17 and the planar frames 11 form a spatial truss structure.

[0033] In the technical solution of the present invention, the four corners of the two planar frames 11 are connected correspondingly by connecting web members 15, and by arranging diagonal web members, a spatial truss stable structure is formed between the diagonal web members 17 and the side of the planar frame 11, thereby improving the overall stiffness and strength of the wind-resistant structure and ensuring the force stability of the wind-resistant structure.

[0034] In addition, preferably, in a specific embodiment of the present invention, at least one horizontal rod 13 and at least one vertical rod 12 may be provided inside each planar frame 11 , so as to further improve the supporting force and reliability of the planar frame 11 .

[0035] Preferably, as an example, in order to ensure the stability of each frame unit 1, a diagonal bar 14 can be added between the horizontal bar 13 and the vertical bar 12. According to the actual stress conditions, the diagonal bar 14 can be added to the position where the frame unit is subjected to greater stress, so as to further improve the wind resistance of the frame unit.

[0036] In addition, as an example, in a preferred embodiment of the present invention, Figure 2As shown, a horizontal web member 16 may be further provided between the two upper plane frames 11 of the top frame unit 1 - 1 to ensure the force bearing performance of the top frame unit 1 - 1 .

[0037] In addition, as an example, in a preferred embodiment of the present invention, Figure 2 As shown, in order to conform to the structural shape of the building, the upper part of the front plane frame 11 of the top frame unit 1-1 can be forward (i.e. Figure 2 The steel structure 100 is bent at a preset angle (in the left direction) to form a receiving portion 111, so as to facilitate the connection with the roof steel structure 100 and adapt to the shape of the building.

[0038] In summary, in the technical solution of the present invention, by connecting the top of the wind-resistant structure with the roof steel structure 100 as one, the facade curtain wall and the eaves laid on the outer surface of the wind-resistant structure can also be designed to be seamlessly integrated, thereby ensuring the beauty of the building. Since the wind-resistant structure is directly connected to the roof steel structure 100, it can also play a better load-bearing role on the facade curtain wall at the junction with the eaves, preventing the curtain wall there from being seriously deformed or torn. By setting a pin support and a sliding support, and setting an expansion joint between the frame units, the wind-resistant structure and the facade curtain wall can be deformed in coordination, so that a large deadweight and temperature deformation will not accumulate at the bottom of the wind-resistant structure, eliminating the risk of the facade curtain wall being torn under the action of load and temperature, and ensuring the appearance requirements and force safety of the eaves and the facade curtain wall being seamlessly connected. Furthermore, by setting the wind-resistant structure in sections, only the top frame unit 1-1 is suspended and connected under the roof steel structure 100, which reduces the load on the roof steel structure and is more conducive to the realization of a lightweight shape of the roof steel structure. In addition, the dead weight of each frame unit is small, making it easier to construct.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
