Description

Technical Field

[0001] This utility model relates to the field of curtain wall technology, specifically to a reinforcing rib for aluminum curtain wall panels. Background Technology

[0002] Aluminum curtain wall panels are structural components with a panel surface and four folded edges, formed by processing high-quality aluminum alloy sheets as the base material and through CNC bending and other technologies. This material is lightweight, not easy to get dirty, durable, fireproof, and weather-resistant, and is usually used as a metal curtain wall for building walls.

[0003] The back of aluminum curtain wall panels is typically reinforced with ribs, which provide the panels with high structural strength and compressive resistance. The ribs are usually rigidly connected to the aluminum panels with bolts. However, since aluminum curtain wall panels are typically used outdoors, they are easily affected by high or low temperatures, leading to thermal expansion and contraction and deformation. The rigid connection between the ribs and the panels cannot absorb the temperature deformation and displacement caused by thermal expansion and contraction. This results in the panels being easily pulled and damaged due to the hard contact, affecting their service life and posing safety hazards.

[0004] Furthermore, regarding the aforementioned technical problems with the rigid connection structure between the reinforcing ribs and the aluminum curtain wall panels, existing technologies have proposed flexible connection structures using adhesives. For example, patent document CN213509084U discloses an aluminum panel curtain wall reinforcement structure, which discloses a structure in which the reinforcing ribs are adhered to the back of the unit aluminum panel using an adhesive layer. However, practical analysis has revealed that this technology still has the following technical problems in practical applications:

[0005] 1. In comparison, both the back of the reinforcing ribs and the back of the unit aluminum plates in the patent are flat, which makes the adhesive layer thinner and more difficult to control. This not only makes it difficult to absorb thermal expansion and contraction, but also affects the reinforcing effect of the reinforcing ribs on the structural reinforcement of the unit aluminum plates.

[0006] 2. In contrast, the reinforcing rib in the patent has an open U-shaped cross section. Although it has a certain structural reinforcement effect, based on the experience of a large number of actual projects, the open U-shaped cross section leads to insufficient structural strength of the reinforcing rib. When it encounters thermal expansion and contraction, both the reinforcing rib and the unit aluminum plate are prone to deformation under stress. Utility Model Content

[0007] To overcome the aforementioned technical problems in the prior art, this utility model provides a reinforcing rib for aluminum curtain wall panels. This utility model adopts a hollow rectangular reinforcing rib and designs an adhesive zone on the bonding surface of the reinforcing rib that allows for varying thicknesses of the structural adhesive. This can improve the structural strength of the reinforcing rib while enhancing its bonding effect with the aluminum curtain wall panel and its resistance to deformation. It solves the technical problems of insufficient structural strength, poor bonding effect with the aluminum curtain wall panel, and inability to effectively absorb thermal expansion and contraction in existing reinforcing ribs.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A curtain wall aluminum panel reinforcing rib includes a hollow rib body with a rectangular cross-section. The rib body has an adhesive surface corresponding to the back of the curtain wall aluminum panel. A double-sided adhesive bonding area is provided in the middle of the adhesive surface along the length direction. Symmetrical structural adhesive bonding areas are provided on both sides of the double-sided adhesive bonding area. An adhesive boss protruding from the adhesive surface is provided in the structural adhesive bonding area. The adhesive bosses on both sides of the double-sided adhesive bonding area are symmetrical.

[0010] The adhesive boss has an inverted trapezoidal structure and is located on the side away from the double-sided adhesive bonding area.

[0011] The adhesive boss has an outer edge, and the outer edge has an inclination of 40-50 degrees relative to the back of the aluminum curtain wall panel.

[0012] The rib body is integrally formed from aluminum profile. The rib body also includes an upper side, a left side and a right side. The left side and the right side are parallel, and the bonding surface is the lower side and parallel to the upper side.

[0013] The inner side of the rib body is integrally formed with a supporting rib plate along the length direction, and the two sides of the supporting rib plate are perpendicular to the upper side and the bonding surface, respectively.

[0014] The supporting stiffener is located on the center line along the length of the stiffener body.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] 1. The reinforcing rib provided by the present utility model mainly has two key innovations. One is that the rib body adopts a hollow rectangular structure, which is a closed structure. Compared with the existing reinforcing rib with an open U-shaped structure, it can not only improve the structural strength of the reinforcing rib itself, but also enhance the support structural strength for the curtain wall aluminum plate. The other is that the bonding surface includes a structural adhesive fixing area, a double-sided adhesive fixing area and a bonding boss. During actual use, positioning can be facilitated through the double-sided adhesive fixing area with double-sided adhesive during installation to ensure that the sizes of the structural adhesives on both sides are the same, thereby achieving a better bonding effect. Through the bonding boss, the thickness of the structural adhesive can be adjusted, and an adhesive layer with different thicknesses can be formed between the rib body and the curtain wall aluminum plate, so as to generate a stronger bonding force between the rib body and the curtain wall aluminum plate, thus greatly enhancing the adhesion between the rib body and the curtain wall aluminum plate. By combining these two key innovations, the present utility model can improve the bonding effect and anti-deformation structure between the rib body and the curtain wall aluminum plate while enhancing the structural strength of the rib body, thereby effectively absorbing the stress deformation of the reinforcing rib under physical loads and thermal expansion and contraction conditions.

[0017] 2. The present utility model adopts a bonding boss with an inverted trapezoidal structure, and the outer side of the bonding boss has an inclination of 40 - 50 degrees relative to the back surface of the curtain wall aluminum plate, which can form a relatively large caulking gap on both sides between the rib body and the curtain wall aluminum plate, thus facilitating the rapid and effective filling of the structural adhesive between the rib body and the curtain wall aluminum plate to form an adhesive layer with different thicknesses.

[0018] 3. The rib body of the present utility model is integrally formed by aluminum profiles, and the left side and the right side are parallel to each other, and the bonding surface is the lower side and parallel to the upper side, which is not only convenient for reducing the manufacturing cost of the rib body, but also enables the rib body to have better structural strength.

[0019] 4. The present utility model enables the rib body to form a "day" - shaped structure through the support rib plate, which is beneficial for reducing the weight of the rib body and further improving the self - structural strength of the rib body and the support strength for the curtain wall aluminum plate.

[0025] The aluminum panel reinforcing ribs for curtain walls described in this utility model have been successfully prototyped and tested, and are currently ready for 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.

[0026] like Figure 1-3 As shown, this utility model provides a curtain wall aluminum panel reinforcing rib, including a hollow rib body 3, which is integrally formed from aluminum profile. The cross-section of the rib body 3 is rectangular. The rib body 3 has an adhesive surface 5 corresponding to the back of the curtain wall aluminum panel 1. The rib body 3 also includes an upper side 10, a left side 11, and a right side 12. The left side 11 and the right side 12 are parallel. The adhesive surface 5 is the lower side and parallel to the upper side 10. This makes the cross-section of the rib body 3 have a closed structure, which has the effect of improving the structural strength of the rib body 3 itself and improving the supporting structural strength of the curtain wall aluminum panel 1.

[0027] Furthermore, along the length of the rib body 3, a double-sided adhesive bonding area 6 is provided in the middle of the bonding surface 5. Symmetrical structural adhesive bonding areas 7 are provided on both sides of the double-sided adhesive bonding area 6. Each structural adhesive bonding area 7 has a protruding bonding boss 8 protruding from the bonding surface 5. The bonding boss 8 has an inverted trapezoidal structure and is located on the side away from the double-sided adhesive bonding area 6. The two bonding bosses 8 on either side of the double-sided adhesive bonding area 6 are symmetrical. Double-sided adhesive 13 can be fixed to the bonding surface 5 through the double-sided adhesive bonding area 6 for positioning during the installation of the rib body 3. Structural adhesive 14 can be applied to the bonding surface 5 through the structural adhesive bonding area 7 to facilitate effective bonding between the rib body 3 and the curtain wall aluminum panel 1. The thickness of the structural adhesive 14 can be adjusted by using the adhesive boss 8 (specifically, the thickness of the structural adhesive 14 can be adjusted by preparing the rib body 3 with different sizes of adhesive boss 8 according to the specifications of the curtain wall aluminum panel 1), and an adhesive layer of different thickness can be formed between the rib body 3 and the curtain wall aluminum panel 1, thereby stably fixing the rib body 3 to the back of the curtain wall aluminum panel 1, further improving the bonding effect and anti-deformation effect between the rib body 3 and the curtain wall aluminum panel 1.

[0028] like Figure 1 , 3As shown, the adhesive boss 8 has an outer edge, and this outer edge has an inclination of 40-50 degrees relative to the back of the aluminum curtain wall panel 1. Preferably, the inclination of this outer edge relative to the back of the aluminum curtain wall panel 1 is 45 degrees. During installation, the inclined outer edge can form a large gap for applying adhesive with the back of the aluminum curtain wall panel 1, which facilitates the effective filling of structural adhesive 14 between the adhesive surface 5 and the aluminum curtain wall panel 1, and also increases the amount of adhesive applied, thereby improving the stability and reliability of the connection between the rib body 3 and the aluminum curtain wall panel 1.

[0029] like Figure 1 , 3 As shown, a supporting rib plate 9 is integrally formed inside the rib body 3 along the length direction. The two sides of the supporting rib plate 9 are perpendicular to the upper side surface 10 and the bonding surface 5, respectively, and the supporting rib plate 9 is located on the center line of the length direction of the rib body 3. This makes the rib body 3 form a closed H-shaped structure, which has the function of enhancing the structural strength of the rib body 3 and improving the structural strength of the curtain wall aluminum panel 1 while minimizing the weight of the rib body 3.

[0030] The reinforcing rib provided by this utility model can be installed alone on the aluminum panel 1 of the curtain wall, or it can be used in conjunction with the adapter 4. Figure 3 This diagram shows a structural schematic of a reinforcing rib installed separately on aluminum panel 1 of the curtain wall. Figure 4 A schematic diagram shows the structure of the reinforcing rib and the adapter 4 installed on the aluminum curtain wall panel 1. The adapter 4 can be structured as follows: it includes a panel body, with symmetrical L-shaped structural members extending into the rib body 3 on one side. The L-shaped structural members cooperate with the panel body to form inner grooves facing the left side 11 and right side 12 respectively. The other side of the panel body has two ends formed by vertical bending to form outer grooves facing the folded edge 2. First, structural adhesive 14 is applied to the inner groove, and the L-shaped structural members are inserted into the rib body 3 to achieve bonding and fixation between the adapter 4 and the rib body 3. Then, structural adhesive 14 is applied to the outer groove, and the rib body 3 and the adapter 4, which are fixed together, are placed between the folded edges 2 of the aluminum curtain wall panel 1 to achieve bonding and fixation between the adapter 4 and the folded edges 2 of the aluminum curtain wall panel 1.

[0031] by Figure 3 For example, the specific installation process in this embodiment is as follows: First, double-sided adhesive 13 is adhered in the double-sided adhesive bonding area 6. Then, the rib body 3 is placed in the corresponding position on the back of the curtain wall aluminum panel 1, and the rib body 3 is adhered and fixed to the back of the curtain wall aluminum panel 1 using double-sided adhesive 13. At this time, the rib body 3 is positioned on the back of the curtain wall aluminum panel 1 by double-sided adhesive 13. Then, using the adhesive notch, structural adhesive 14 is applied to the structural adhesive bonding area 7 between the rib body 3 and the back of the curtain wall aluminum panel 1. When the structural adhesive 14 is filled, an adhesive layer with varying thickness and better bonding effect can be obtained, thereby effectively strengthening the rib under physical load and thermal expansion and contraction conditions.

[0032] Test case

[0033] The applicant used the reinforcing rib disclosed in patent document CN213509084U as a comparative reinforcing rib, and conducted tensile tests on the reinforcing rib of this utility model and the comparative reinforcing rib under the same conditions. The test results are shown in Table 1 below:

[0034] Table 1

[0035]

[0036] As can be seen from the above test data, this utility model, due to the use of a reinforcing rib with a specific structure and its flexible connection to the aluminum curtain wall panel via adhesive, can improve the bonding effect and anti-deformation structure of the reinforcing rib with the aluminum curtain wall panel while enhancing the structural strength of the rib itself, compared with the prior art with announcement number CN213509084U. This effectively absorbs the stress deformation of the reinforcing rib under physical load and thermal expansion and contraction conditions.
