Description

Technical Field

[0001] The utility model relates to the technical field of glass curtain wall accessories, in particular to a cable glass curtain wall edge connection structure. Background Art

[0002] The cable-stayed curtain wall system, a building facade system that utilizes tension to transmit loads, consists of high-strength steel cables, connectors, and curtain wall panels. By suspending or supporting the curtain wall panels on the cables, the system not only reduces the burden on the frame structure but also provides a unique aesthetic effect. During normal operation, the cables deform into a parabolic shape to resist wind loads. Under wind loads, the four corners of the curtain wall's glass panels deform out of planarity, creating angles between adjacent panes. This is particularly true for corner panes, where one side is connected to the building structure with a U-shaped channel and the other side is attached to the cables with a clamp. When the cables deflect, the glass on the cable side experiences significant displacement perpendicular to the glass, while the side fixed to the steel frame experiences almost no displacement. The glass rotates, and the greater the wind load, the greater the angle of rotation. Under extreme wind loads, the glass can be excessively squeezed against the U-shaped channel, causing some horizontal displacement, compromising its safety. Based on this, in order to address the safety risks caused by the rotation of glass in the cable curtain wall system, it is necessary to provide a more targeted glass edge connection structure. Utility Model Content

[0003] The purpose of the utility model is to provide a cable-type glass curtain wall edge connection structure to solve the deficiencies in the prior art.

[0004] To achieve these objectives, the present application provides the following technical solution: a cable-type glass curtain wall edge connection structure, comprising a first connecting member and a second connecting member, wherein the first connecting member can be fixedly connected to the building body, and the second connecting member includes at least a U-shaped groove for fixing the curtain wall glass, and the second connecting member is hinged to the first connecting member through a pin shaft, and the U-shaped groove can rotate around the pin shaft.

[0005] As a preferred embodiment, the pin shaft can move radially relative to the first connecting member and / or the second connecting member; at least one of the first connecting member and the second connecting member has a space for the pin shaft to move radially.

[0006] As a preferred embodiment, the first end pin shaft head and the second end pin shaft head of the pin shaft are cooperated with the first ear plate member, and the middle part of the pin shaft between the first end pin shaft head and the second end pin shaft head of the pin shaft is cooperated with the second ear plate member, and the space for radial movement of the pin shaft is set on the first ear plate member or the second ear plate member.

[0007] As a preferred embodiment, the number of ear plates in the first ear plate member is greater than or equal to the number of the second ear plate member.

[0008] As a preferred embodiment, the first ear plate member is arranged on the first connecting member, and the ear plate is arranged on the second connecting member.

[0009] As a preferred embodiment, the first ear plate member is arranged on the second connecting member, and the ear plate is arranged on the first connecting member.

[0010] As a preferred embodiment, on the first ear plate member and / or the second ear plate member, the space for radial movement of the pin shaft includes a first oblong fixing hole.

[0011] As a preferred embodiment, the length direction of the first fixing hole is perpendicular or parallel to the plane where the cable curtain wall is located.

[0012] As a preferred embodiment, on the first ear plate or the second ear plate, the space for radial movement of the pin includes a first fixing hole in the shape of an elongated arc.

[0013] As a preferred embodiment, the arc-shaped chord in the first fixing hole is arranged perpendicular to the plane where the cable curtain wall is located.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] In traditional cable-stayed curtain wall structures, one side of the glass at the edge is fixed to the building structure via a U-shaped groove. This connection method is ineffective in dealing with the rotation of the curtain wall glass caused by excessive deflection when subjected to high wind loads, especially in typhoon-prone areas. This rotation can lead to problems such as excessive compression of the glass against the U-shaped groove.

[0016] To address this issue, the present invention incorporates a first and second connector into a U-shaped channel, creating a hinged connection. This design allows the U-shaped channel to adapt to the rotation of the glass, preventing excessive compression between the glass and the U-shaped channel. This enhances the safety and stability of the glass in the cable curtain wall system. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See Figure 1In a cable-stayed curtain wall system, when the cables deform into a parabolic shape to resist wind loads, the curtain wall also becomes hyperbolic, causing the four corners of the curtain wall's glass panels to deform out of planarity and creating angles between adjacent glass panels. In particular, the glass panels 1, attached to the building structure 2 at their edges, are connected to the building structure 2 on one side using a U-shaped groove 3 and to the clamps on the cables on the other side. When the cables experience excessive deflection, the side fixed to the building structure 2 experiences almost no displacement perpendicular to the glass, while the side attached to the cables experiences a displacement of up to R1 perpendicular to the glass, causing the glass to rotate by an angle θ. Simultaneously, due to the rotation of the glass, the glass undergoes a horizontal displacement of R2, impacting its safe use.

[0028] The following embodiments provided in this application are all improvements made to the above-mentioned connection method, which is difficult to effectively cope with the rotation of curtain wall glass caused by excessive deflection in areas with large wind loads, especially in areas with frequent typhoons.

[0029] For example 1, see Figure 2 A cable-stayed glass curtain wall edge connection structure includes a first connecting member 4 and a second connecting member 5. The first connecting member 4 can be fixedly connected to the building body 2. The second connecting member 5 includes a U-shaped groove 3 for fixing the curtain wall glass 1. The second connecting member 5 is hinged to the first connecting member 4 through a pin 6, and the U-shaped groove 3 can rotate around the pin 6.

[0030] By forming a hinge in this way, when the cable produces excessive deflection, the U-shaped groove 3 is allowed to adaptively rotate when the glass 1 rotates, avoiding excessive squeezing of the glass 1 and the U-shaped groove 3, enhancing the safety and stability of the glass in the cable curtain wall system, and is particularly suitable for use in cable curtain wall structures in areas with large wind loads and frequent typhoons.

[0031] More specifically, a number of lugs may be provided between the first connecting member 4 and the second connecting member 5 to cooperate with the pin 6, see Figure 3 In this embodiment, a single-double ear plate connection form is used as an example. The first end pin head 61 and the second end pin head 62 of the pin shaft 6 are cooperated with the first ear plate component 7. The first ear plate component 7 includes two ear plates. The middle part of the pin shaft between the first end pin head 61 and the second end pin head 62 of the pin shaft 6 is cooperated with the second ear plate component 8. The second ear plate component 8 includes an ear plate. The first ear plate component 7 is arranged on the first connecting member 4, and the second ear plate component 8 is arranged on the second connecting member 5.

[0032] The above examples illustrate the connection form of single-double ear plates. It is clear to those skilled in the art that the connection form of the present application is not limited to the form shown in the above examples. For example, see Figure 4In order to improve the strength of the connection, the first ear plate member 7 and the second ear plate member 8 can also adopt a double-triple ear plate connection form, or other equivalent connection forms, or the first ear plate member 7 can also be arranged on the second connecting member 5, and the second ear plate member 8 can be arranged on the first connecting member 4. These connection forms can achieve the same or similar effects as the present embodiment, so they are not described one by one.

[0033] For example 2, see Figure 5 On the basis of the first embodiment, the first fixing hole 9 on the first connecting member 4 that cooperates with the pin 6 is an oblong hole, and the pin 6 is slidably arranged in the first fixing hole 9. The length direction of the first fixing hole 9 is arranged perpendicular to the plane where the cable curtain wall is located; so that when subjected to wind load, the U-shaped groove can not only rotate with the rotation of the curtain wall glass, but also move back and forth in a direction perpendicular to the plane of the curtain wall, so as to better adapt to the dynamic changes of the curtain wall glass and reduce the risk of local extrusion caused by excessive deflection.

[0034] In some embodiments of this application, see Figure 6 The length direction of the first fixing hole 6 can also be arranged parallel to the plane where the cable curtain wall is located, or the length direction of the first fixing hole 6 is arranged at an angle to the plane where the cable curtain wall is located, or the first fixing hole 9 is arranged on the second connecting member 5. These arrangements can also achieve the same or similar effects as those of the second embodiment, so they will not be described in detail one by one.

[0035] In some embodiments of the present application, in addition to the above-mentioned oblong hole, when one of the first connecting member 4 and the second connecting member 5 has a space for radial movement of the pin shaft, the same or similar effect as that of the second embodiment can also be achieved. For example, see Figure 7 The first fixing hole 9 is set as an elongated arc hole, allowing the pin 6 to move along an arc trajectory. It can be understood that in order to enable the U-shaped groove 3 to better adapt to the changes of the curtain wall glass 1 during movement, the arc chord in the first fixing hole 9 is set perpendicular to the plane where the cable curtain wall is located.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
