Abstract
Description
Technical Field
[0001] This utility model relates to the field of curtain wall technology, specifically to a flexible connector for connecting the reinforcing ribs and folded edges of aluminum curtain wall panels. Background Technology
[0002] Aluminum curtain wall panels refer to composite aluminum panels installed on the exterior walls of buildings. They do not bear any weight and are fixed to the wall like a curtain. They are a commonly used lightweight wall material with decorative effects in modern large and high-rise buildings. Moreover, aluminum curtain wall panels have a unique texture, rich colors, and diverse shapes. They are lightweight and can be perfectly combined with glass curtain wall materials and stone curtain wall materials. Their perfect appearance and excellent quality make them highly favored by the building materials and decoration industry.
[0003] The back of aluminum curtain wall panels is typically fitted with reinforcing ribs, which give the panels high structural strength and compressive resistance. There are two main connection methods between the reinforcing ribs and the aluminum curtain wall panels:
[0004] 1. Bolted hard connection: Since aluminum curtain wall panels are usually used outdoors, they are easily affected by high or low temperatures, causing thermal expansion and contraction and deformation. Although this hard connection method can effectively fix the reinforcing ribs to the aluminum curtain wall panel, it cannot absorb the temperature deformation and displacement caused by thermal expansion and contraction. Instead, it is easy to damage the aluminum curtain wall panel due to hard contact and pulling, which affects the service life of the aluminum curtain wall panel.
[0005] 2. Flexible adhesive connection: For example, patent document CN213509084U discloses a reinforcement structure for aluminum panel curtain walls, which discloses a structure in which reinforcing ribs are adhered to the back of unit aluminum panels via an adhesive layer. This flexible connection method can partially solve the technical problems of the aforementioned rigid connection method. This is because the reinforcing ribs in this patent document are only flexibly bonded to the back of the aluminum panel, and are not simultaneously flexibly connected to the folded edges of the aluminum panel. This not only results in poor thermal expansion and contraction absorption, but also affects the overall reinforcement effect of the reinforcing ribs on the aluminum panel, leading to insufficient overall load-bearing capacity of the aluminum panel. Utility Model Content
[0006] To overcome the aforementioned technical problems in the prior art, this utility model provides a flexible connector for linking the reinforcing ribs and folded edges of curtain wall aluminum panels. This utility model aims to achieve flexible bonding between the reinforcing ribs and the curtain wall aluminum panels, while simultaneously achieving flexible bonding between the reinforcing ribs and the folded edges of the curtain wall aluminum panels. This solves the technical problems of insufficient overall load-bearing capacity of curtain wall aluminum panels and the inability to effectively absorb thermal expansion and contraction in the prior art.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A flexible connector for linking the reinforcing ribs and folded edges of an aluminum curtain wall panel includes a connector body. One side of the connector body is symmetrically provided with rib bonding structures for extending into the reinforcing ribs, and the other side of the connector body is provided with an edge bonding structure. The rib bonding structure has a rib bonding area for accommodating adhesive, and the edge bonding structure has an edge bonding area for accommodating adhesive. The rib bonding structure is used to bond and fix the reinforcing ribs with adhesive in the rib bonding area, and the edge bonding structure is used to bond and fix the edge with adhesive in the edge bonding area.
[0009] The adapter body has a flat plate structure, and the rib bonding structure is L-shaped. The rib bonding structure is vertically fixed in the width direction of the adapter body, and the rib bonding area is a groove structure formed by the rib bonding structure and the adapter body.
[0010] The rib bonding structure is spaced from the end of the adapter body.
[0011] The length of the rib bonding structure is the same as the width of the adapter body.
[0012] The folded edge bonding structure consists of vertically bent portions at both ends of the adapter body, and the folded edge bonding area is a groove structure formed by the vertically bent portions and the adapter body.
[0013] The length of the folded edge bonding structure is the same as the width of the adapter body.
[0014] Compared with the prior art, the advantages of this utility model are:
[0015] 1. The adapter provided by this utility model is designed with a rib bonding structure and an edge bonding structure that can be respectively bonded and fixed to the reinforcing rib and the edge of the curtain wall aluminum panel. This structure allows the reinforcing rib to be flexibly connected to the back of the curtain wall aluminum panel, and also to the edge of the curtain wall aluminum panel. The structural adhesive has extremely high bonding strength, and the components are flexibly connected. When applied to the curtain wall aluminum panel, the reinforcing rib, the back of the curtain wall aluminum panel, and the edge form an integrated flexible force-bearing system. This ensures effective connection of each component to enhance structural strength, and effectively absorbs temperature deformation and displacement caused by thermal expansion and contraction. Even if the curtain wall aluminum panel experiences thermal expansion and contraction under the influence of high or low external temperatures, this flexible connection structure can achieve self-compensation, resist various adverse conditions in the outdoor environment, and prevent the curtain wall aluminum panel from deforming and being damaged. Thus, it can effectively improve the service life of the curtain wall aluminum panel while ensuring its structural strength and flatness.
[0016] 2. This utility model uses a specific structure of adapter, which can form a stable and unchanging groove structure, ensuring that the amount, position and shape of the structural adhesive are consistent, which is conducive to improving the connection stability and reliability of each component.

[0022] The structural reinforcement component described in this utility model has been successfully prototyped and tested, and is currently ready for mass production. To better protect this technology, the applicant has filed a patent application. The following description, in conjunction with embodiments, further illustrates this utility model.
[0023] like Figure 1 , 2 As shown, this utility model proposes a flexible connector for connecting the reinforcing ribs and folded edges of a curtain wall aluminum panel. It includes a connector body 4, with symmetrical rib bonding structures 5 extending into the reinforcing rib 3 on one side of the connector body 4, and an edge bonding structure 6 on the other side of the connector body 4. The rib bonding structure 5 has a rib bonding area for accommodating adhesive, and the edge bonding structure 6 has an edge bonding area for accommodating adhesive. The rib bonding structure 5 is used to bond and fix the reinforcing rib 3 to the side edge of the reinforcing rib 3 (such as the left and right sides of the U-shaped reinforcing rib 3 in patent document CN213509084U) using adhesive in the rib bonding area. The edge bonding structure 6 is used to bond and fix the edge 2 to the folded edge 2 using adhesive in the edge bonding area, so that the reinforcing rib 3 is flexibly bonded to the curtain wall aluminum panel 1 while simultaneously achieving a flexible bonded connection with the edge 2 of the curtain wall aluminum panel 1.
[0024] In this utility model, such as Figure 1 , 2 As shown, the adapter body 4 has a flat plate structure, and the rib bonding structure 5 is L-shaped. The rib bonding structure 5 is vertically fixed in the width direction of the adapter body 4, and the rib bonding area is a groove structure formed by the cooperation of the rib bonding structure 5 and the adapter body 4. The folded edge bonding structure 6 is the vertical bending part at both ends of the adapter body 4, and the folded edge bonding area is a groove structure formed by the cooperation of the vertical bending part and the adapter body 4.
[0025] Furthermore, the length of the folded edge bonding structure 6 is the same as the width of the adapter body 4, the length of the rib bonding structure 5 is the same as the width of the adapter body 4, and there is a gap between the rib bonding structure 5 and the end of the adapter body 4 so that the rib bonding structure 5 can be inserted into the reinforcing rib 3.
[0026] This invention can achieve a stable and unchanging groove structure, ensuring that the amount, position, and shape of the structural adhesive 7 are consistent during use, thereby making the connection between the adapter, the reinforcing rib 3, and the aluminum edge of the curtain wall aluminum panel 1 more stable and reliable.
[0027] Taking the application of the adapter between the reinforcing rib 3 and the folded edge 2 disclosed in the patent document with publication number CN213509084U as an example, the specific installation process of this utility model is as follows:
[0028] 1. For example Figure 2-4 As shown, structural adhesive 7 is first applied to the rib bonding area of the rib bonding structure 5, and then the rib bonding structures 5 of the two adapter bodies 4 are inserted into the reinforcing rib 3 from both ends of the reinforcing rib 3, thereby using adhesive to bond and fix the adapter body 4 to the reinforcing rib 3.
[0029] 2. Apply structural adhesive 7 to the plane opposite to the back of the aluminum curtain wall panel 1 on the reinforcing rib 3. Use the adhesive to fix the reinforcing rib 3 to the back of the aluminum curtain wall panel 1. At this time, both the reinforcing rib 3 and the adapter body 4 are fixed to the back of the aluminum curtain wall panel 1, and the folded edge bonding structure 6 of the adapter body 4 abuts against the folded edge 2 of the aluminum curtain wall panel 1.
[0030] 3. Apply structural adhesive 7 to the folded edge bonding area of the folded edge bonding structure 6. After applying the structural adhesive 7, a flexible connection structure is obtained in which the reinforcing rib 3 is bonded and fixed to the back of the curtain wall aluminum panel 1, and at the same time, it is bonded and fixed to the folded edge 2 of the curtain wall aluminum panel 1 through the adapter body 4.
[0031] After the applicant bonded and fixed the adapter provided by this utility model between the folded edge 2 and the reinforcing rib of the aluminum curtain wall panel 1, a tensile test was conducted on it. The test results are shown in Table 1 below:
[0032] Table 1
[0033]
[0034] As can be seen from the above test data, since the adapter is flexibly connected to the folded edge 2 and the reinforcing rib 3 of the aluminum panel 1, the aluminum panel 1 can form an integral flexible force-bearing system. This ensures that the components are effectively connected to enhance the structural strength, and can effectively absorb the temperature deformation and displacement caused by thermal expansion and contraction, thus making the service life of the aluminum panel 1 longer.
[0035] The above description is only a specific embodiment of the present utility model. Any feature disclosed in this specification may be replaced by other equivalent or similar features unless otherwise specified. All features or steps in all methods or processes disclosed may be combined in any way except for mutually exclusive features and / or steps.
