Description

Technical Field

[0001] The utility model belongs to the technical field of composite panels, and in particular relates to an anti-deformation structure of a curtain wall composite panel. Background Art

[0002] In modern architecture, curtain walls, as a crucial component of building exteriors, not only provide aesthetics and decoration but also directly impact the building's safety, durability, and functionality. Composite panels, particularly aluminum-plastic panels, are widely used in curtain wall systems due to their light weight, high strength, ease of fabrication, and excellent decorative properties.

[0003] Curtain wall aluminum-plastic panels usually include an outer aluminum panel, an inner aluminum panel and an intermediate plastic panel. When the curtain wall aluminum-plastic panels are in use, the edges of the outer aluminum panel are usually directly connected to the supporting structure (such as the curtain wall frame). These connection points are fixed by fasteners such as bolts and angle brackets, forming the main stress points of the outer aluminum panel. Due to the action of force lines, these fixed points will be subjected to a large concentrated force, which can easily cause the edges of the outer aluminum panel to deform during long-term use, especially in areas with large wind loads or drastic temperature changes. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a curtain wall composite panel anti-deformation structure for solving the problems in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides a curtain wall composite panel anti-deformation structure, comprising:

[0006] An outer aluminum plate, a plastic plate, and an inner aluminum plate are sequentially arranged along a first direction;

[0007] And the sub-frame is fixedly mounted on the outside of the outer aluminum plate to enhance the rigidity and bending resistance of the edge of the outer aluminum plate;

[0008] Among them, the outer aluminum plate is used to resist external loads; the plastic plate is installed on the outer aluminum plate, and the plastic plate can be used for sound insulation and heat insulation; the inner aluminum plate is installed on the plastic plate, and the inner aluminum plate is used to connect with the curtain wall frame.

[0009] Through this design, the sub-frame significantly enhances the rigidity and bending resistance of the edge of the outer aluminum plate, preventing the edge from deformation or damage due to external forces; at the same time, the sub-frame provides a reliable support point for subsequent installation and fixing work, such as connection with the main structure and laying of the waterproof layer.

[0010] Preferably, the plastic plate is mounted on the outer aluminum plate via a first elastic gasket, and the inner aluminum plate is mounted on the plastic plate via a second elastic gasket.

[0011] Through this design, the first elastic gasket acts as a buffer layer, effectively isolating the direct contact between the plastic plate and the outer aluminum plate, reducing the risk of wear; on the other hand, when the outer aluminum plate is subjected to external force, the first elastic gasket can absorb and disperse part of the stress, preventing damage caused by stress concentration.

[0012] Preferably, the outer aluminum plate, plastic plate, inner aluminum plate, first elastic gasket and second elastic gasket have the same size, and their sides are aligned.

[0013] Through this design, the side edges of the outer aluminum plate, plastic plate, inner aluminum plate, first elastic gasket and second elastic gasket are all aligned. Since the sizes of the various structures are the same and the sides are aligned, this design presents a high degree of neatness and consistency in appearance. For application scenarios such as building curtain walls, this design can enhance the overall aesthetics and make the building appearance more harmonious and unified.

[0014] Preferably, the sub-frame has an inner cavity, and the outer aluminum plate, the plastic plate, and each part of the inner aluminum plate are fixedly arranged in the inner cavity; the outer aluminum plate, the plastic plate, the inner aluminum plate, and the inner cavity are all of the same size;

[0015] The sum of the thicknesses of the outer aluminum plate, the plastic plate and the inner aluminum plate is the same as the thickness of the inner cavity.

[0016] Through this design, the gaps between the composite panels can be minimized or eliminated to the greatest extent, improving the sealing and thermal insulation performance of the curtain wall; at the same time, the close fit between the sub-frame and the outer aluminum panel, plastic panel and inner aluminum panel helps to enhance the structural strength of the entire composite panel and improve the overall stability and durability of the curtain wall system.

[0017] Preferably, the sub-frame has an inner cavity, all parts of the outer aluminum plate are fixedly arranged in the inner cavity, and all parts of the plastic plate and the inner aluminum plate are arranged outside the inner cavity; the size and thickness of the outer aluminum plate are respectively the same as the size and thickness of the inner cavity.

[0018] Preferably, the outer aluminum plate, the plastic plate and the inner aluminum plate have the same size, and the sides of the outer aluminum plate, the plastic plate and the inner aluminum plate are aligned.

[0019] With such a design, on the one hand, the sub-frame only needs to be connected to the outer aluminum plate; on the other hand, the connection between the sub-frame and the outer aluminum plate does not involve the plastic plate, so there are fewer material compatibility issues.

[0020] Preferably, the sub-frame and the outer aluminum plate form an outer structure, the outer structure, the plastic plate and the inner aluminum plate have the same size, and the sides of the outer structure, the plastic plate and the inner aluminum plate are aligned.

[0021] Through this design, the sub-frame only needs to be connected to the outer aluminum plate. At the same time, the gaps between the composite panels can be eliminated. This seamless design can improve the appearance quality of the curtain wall and make the overall look smoother and more beautiful.

[0022] Preferably, a plurality of reinforcing ribs are installed on the side of the inner aluminum plate facing away from the outer aluminum plate, and the reinforcing ribs are arranged in parallel and spaced apart;

[0023] The reinforcing ribs all include a first reinforcing sub-rib and a plurality of second reinforcing sub-ribs connected to the first reinforcing sub-ribs, and the first reinforcing sub-ribs and the second reinforcing sub-ribs are both installed on the inner aluminum plate.

[0024] This design allows the ribs to be installed on the inner aluminum sheet, directly increasing its rigidity. Although the ribs don't directly contact the outer aluminum sheet, they indirectly impact the overall curtain wall composite panel by increasing its rigidity and stability. This impact helps reduce deformation or vibration of the outer aluminum sheet under external influences.

[0025] Preferably, at least part of the edge portions of the outer aluminum plate, the plastic plate and the inner aluminum plate are bent.

[0026] Through such a design, it can be regarded as a folding treatment of the curtain wall composite panel composed of the outer aluminum panel, the plastic panel and the inner aluminum panel. The folding treatment can solve the stress concentration phenomenon at the edge of the curtain wall composite panel. By folding, the stress originally concentrated on the edge can be dispersed to a larger area, thereby reducing the risk of damage caused by excessive local stress.

[0027] Preferably, the thickness of the outer aluminum plate and the inner aluminum plate are both smaller than the thickness of the plastic plate.

[0028] The beneficial effects of the present invention are as follows: the sub-frame is fixedly sleeved on the outside of the outer aluminum plate, and the sub-frame, the outer aluminum plate, the plastic plate, and the inner aluminum plate together form an anti-deformation structure. Based on this, on the one hand, the sub-frame significantly enhances the rigidity and bending resistance of the edge of the outer aluminum plate, preventing the edge from being deformed or damaged due to external forces; on the other hand, the sub-frame provides a reliable support point for subsequent installation and fixing work, such as connection with the main structure, laying of the waterproof layer, etc.; on the other hand, through the introduction of the sub-frame, the concentrated stress on the edge of the outer aluminum plate is effectively dispersed, reducing deformation and damage caused by stress concentration.

[0048] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0049] Example 1

[0050] like Figures 1 to 8 As shown, the utility model provides a curtain wall composite panel anti-deformation structure, comprising:

[0051] An outer aluminum plate 1, a plastic plate 2, and an inner aluminum plate 3 are sequentially arranged along a first direction;

[0052] and a sub-frame 4, which is fixedly sleeved on the outside of the outer aluminum plate 1 and is used to enhance the rigidity and bending resistance of the edge of the outer aluminum plate 1;

[0053] Among them, the outer aluminum plate 1 is used to resist external loads; the plastic plate 2 is installed on the outer aluminum plate 1, and the plastic plate 2 can be used for sound insulation and heat insulation; the inner aluminum plate 3 is installed on the plastic plate 2, and the inner aluminum plate 3 is used to connect with the curtain wall frame.

[0054] The first direction is the x direction in the figure.

[0055] The main body of the anti-deformation structure of the curtain wall composite panel is an outer aluminum plate 1, a plastic plate 2, an inner aluminum plate 3 and a sub-frame 4. Among them, the outer aluminum plate 1 is in contact with the external environment and can be used to resist external loads; the plastic plate 2 is arranged between the outer aluminum plate 1 and the inner aluminum plate 3 and can be used for sound insulation and heat insulation; the inner aluminum plate 3 is used to connect with the curtain wall frame; the sub-frame 4 is used to enhance the rigidity and bending resistance of the edge of the outer aluminum plate 1.

[0056] Optionally, the outer aluminum plate 1 and inner aluminum plate 3 are made of aluminum alloy plates with a thickness of 0.5mm to 1.0mm, which have good wind pressure resistance and corrosion resistance. The plastic plate 2 is made of a high-strength, weather-resistant plastic material, such as polyethylene (PE) or polyvinyl chloride (PVC), and has a thickness of 2mm to 5mm. The outer aluminum plate 1 and inner aluminum plate 3 are respectively arranged on either side of the plastic plate 2 and are tightly bonded to the plastic plate 2 through a specific connection method (such as gluing or mechanical fastening), but do not completely enclose the plastic plate 2 to maintain a certain degree of air permeability.

[0057] The outer aluminum plate 1, the plastic plate 2, and the inner aluminum plate 3 can form an aluminum-plastic panel, and the connection method between the three can refer to the installation method between the various structures in the existing aluminum-plastic panel.

[0058] Providing the plastic plate 2 can reduce the overall weight of the aluminum-plastic plate; at the same time, the plastic material itself has a certain moisture-proof property, which can prevent moisture from penetrating into the internal structure; and compared with pure aluminum plates, the plastic plate 2 has better impact resistance, and can resist the impact of external forces to a certain extent without being easily damaged; in addition, the porous structure or special design inside the plastic plate 2 helps to absorb and isolate sound, providing a certain sound insulation effect for the building.

[0059] The anti-deformation structure of the curtain wall composite panel is installed on the curtain wall frame during use, and the curtain wall frame is installed on a wall or other structure. For details, please refer to the existing installation methods for curtain wall composite panels, curtain wall frames, and wall structures. When the sub-frame 4 is not provided, the curtain wall composite panel is typically connected to the curtain wall frame via fixed structures (such as corner brackets, hanging parts, etc.) on its edges. These fixed parts pass through the reserved holes or slots in the panel and are fastened to the connecting structures (such as bolts, welded parts, etc.) on the curtain wall frame. When the sub-frame 4 is provided, the curtain wall composite panel is typically connected to the sub-frame 4 via the reserved holes or slots on its edges.

[0060] The sub-frame 4 is fixedly mounted on the outside of the outer aluminum plate 1, and the sub-frame 4, the outer aluminum plate 1, the plastic plate 2, and the inner aluminum plate 3 together form an anti-deformation structure; on the one hand, the sub-frame 4 significantly enhances the rigidity and bending resistance of the edge of the outer aluminum plate 1, preventing the edge from being deformed or damaged due to external forces; on the other hand, the sub-frame 4 provides a reliable support point for subsequent installation and fixing work, such as connection with the main structure, laying of the waterproof layer, etc.; on the other hand, through the introduction of the sub-frame 4, the concentrated stress on the edge of the outer aluminum plate 1 is effectively dispersed, reducing deformation and damage caused by stress concentration.

[0061] Optionally, the sub-frame 4 is made of an aluminum alloy material having the same or higher strength as the aluminum plate.

[0062] Optionally, the sub-frame 4 and the outer aluminum plate 1 are fixed with both rivets and structural adhesive. The rivets provide mechanical strength, and the structural adhesive enhances bonding strength, thereby ensuring the stability of the connection.

[0063] Example 2

[0064] In this embodiment, the plastic plate 2 is mounted on the outer aluminum plate 1 via a first elastic gasket 5 , and the inner aluminum plate 3 is mounted on the plastic plate 2 via a second elastic gasket 6 .

[0065] Optionally, the first elastic gasket 5 and the second elastic gasket 6 are made of silicone or highly elastic rubber.

[0066] Taking the first elastic gasket 5 as an example, through the setting of the first elastic gasket 5, on the one hand, the first elastic gasket 5 acts as a buffer layer, effectively isolating the direct contact between the plastic plate 2 and the outer aluminum plate 1, reducing the risk of wear; on the other hand, when the outer aluminum plate 1 is subjected to external force, the first elastic gasket 5 can absorb and disperse part of the stress to prevent damage caused by stress concentration; on the other hand, the first elastic gasket 5 also has a certain shock-absorbing effect, which can reduce the vibration and noise transmission of the plate caused by factors such as wind load and temperature changes.

[0067] Example 3

[0068] Reference Figure 5 In this embodiment, the sizes of the outer aluminum plate 1, the plastic plate 2, the inner aluminum plate 3, the first elastic gasket 5 and the second elastic gasket 6 are all the same, and the side edges of the outer aluminum plate 1, the plastic plate 2, the inner aluminum plate 3, the first elastic gasket 5 and the second elastic gasket 6 are all aligned.

[0069] It should be noted that the dimensions of the outer aluminum plate 1, the plastic plate 2, the inner aluminum plate 3, the first elastic gasket 5 and the second elastic gasket 6 are all the same, which means that these components are consistent in dimensions such as length and width (or diameter if it is a circular structure). For other descriptions of dimensions in the present invention, refer to this explanation.

[0070] The side edges of the outer aluminum plate 1, the plastic plate 2, the inner aluminum plate 3, the first elastic gasket 5 and the second elastic gasket 6 are all aligned. On the one hand, since the structures have the same size and the sides are aligned, this design presents a high degree of neatness and consistency in appearance. For application scenarios such as building curtain walls, this design can enhance the overall aesthetics and make the building appearance more harmonious and unified; on the other hand, the aligned design helps to reduce stress concentration caused by misalignment or deviation between structures, thereby enhancing the structural stability of the entire composite board; on the other hand, in this design, if appropriate sealing measures (such as sealants, sealing strips, etc.) are adopted between the structures, the sealing performance of the composite board can be significantly improved.

[0071] Example 4

[0072] Reference Figure 1 In this embodiment, the sub-frame 4 has an inner cavity 41, and the outer aluminum plate 1, the plastic plate 2, and the inner aluminum plate 3 are all fixedly disposed in the inner cavity 41; the outer aluminum plate 1, the plastic plate 2, the inner aluminum plate 3, and the inner cavity 41 have the same dimensions;

[0073] The sum of the thicknesses of the outer aluminum plate 1 , the plastic plate 2 and the inner aluminum plate 3 is the same as the thickness of the inner cavity 41 .

[0074] There are many specific forms of installing the sub-frame 4, and this embodiment is one of them.

[0075] The sub-frame 4 has an inner cavity 41, and all parts of the outer aluminum plate 1, the plastic plate 2 and the inner aluminum plate 3 are fixedly arranged in the inner cavity 41; the dimensions of the outer aluminum plate 1, the plastic plate 2, the inner aluminum plate 3 and the inner cavity 41 are all the same; the sum of the thicknesses of the outer aluminum plate 1, the plastic plate 2 and the inner aluminum plate 3 is the same as the thickness of the inner cavity 41; through the above three settings, the sub-frame 4 can completely cover the outer aluminum plate 1, the plastic plate 2 and the inner aluminum plate 3 in the circumferential direction, and can also achieve the outer aluminum plate 1, the plastic plate 2 and the inner aluminum plate 3 to completely fill the inner cavity 41, and can also avoid the sub-frame 4 protruding from the outer aluminum plate 1 or the inner aluminum plate 3 in the first direction.

[0076] Through some settings in this embodiment, the gaps between the composite panels can be minimized or eliminated to the greatest extent, thereby improving the sealing and thermal insulation performance of the curtain wall; at the same time, the close fit between the sub-frame 4 and the outer aluminum panel 1, the plastic panel 2 and the inner aluminum panel 3 helps to enhance the structural strength of the entire composite panel and improve the overall stability and durability of the curtain wall system.

[0077] Optionally, the outer aluminum plate 1 , the plastic plate 2 and the inner aluminum plate 3 are all connected to the sub-frame 4 .

[0078] Example 5

[0079] In this embodiment, the sub-frame 4 has an inner cavity 41, and all parts of the outer aluminum plate 1 are fixedly arranged in the inner cavity 41, and all parts of the plastic plate 2 and the inner aluminum plate 3 are arranged outside the inner cavity 41; the size and thickness of the outer aluminum plate 1 are respectively the same as the size and thickness of the inner cavity 41.

[0080] Example 6

[0081] Reference Figure 2 In this embodiment, the outer aluminum plate 1, the plastic plate 2 and the inner aluminum plate 3 have the same size, and the sides of the outer aluminum plate 1, the plastic plate 2 and the inner aluminum plate 3 are aligned.

[0082] There are many specific forms of installing the sub-frame 4, and this embodiment combined with embodiment 5 is one of them.

[0083] The sub-frame 4 has an inner cavity 41, and all parts of the outer aluminum plate 1 are fixedly arranged in the inner cavity 41, and all parts of the plastic plate 2 and the inner aluminum plate 3 are arranged outside the inner cavity 41; the size and thickness of the outer aluminum plate 1 are respectively the same as the size and thickness of the inner cavity 41; the size of the outer aluminum plate 1, the plastic plate 2 and the inner aluminum plate 3 are all the same, and the side edges of the outer aluminum plate 1, the plastic plate 2 and the inner aluminum plate 3 are all aligned; through the above three settings, on the one hand, this design is relatively simple, and the sub-frame 4 only needs to be connected to the outer aluminum plate 1; on the other hand, the connection between the sub-frame 4 and the outer aluminum plate 1 does not involve the plastic plate 2, so there are fewer material compatibility issues.

[0084] It should be noted that, in this embodiment, although the size of the structure composed of the sub-frame 4 and the outer aluminum plate 1 is larger than that of the inner aluminum plate 3, sealing can be ensured by providing sealing strips or sealants between the composite plates.

[0085] Example 7

[0086] Reference Figure 3 In this embodiment, the sub-frame 4 and the outer aluminum plate 1 form an outer structure 7. The outer structure 7, the plastic plate 2 and the inner aluminum plate 3 have the same size, and the side edges of the outer structure 7, the plastic plate 2 and the inner aluminum plate 3 are aligned.

[0087] There are many specific forms of installing the sub-frame 4, and this embodiment combined with embodiment 5 is one of them.

[0088] The sub-frame 4 has an inner cavity 41, and all parts of the outer aluminum plate 1 are fixedly arranged in the inner cavity 41, and all parts of the plastic plate 2 and the inner aluminum plate 3 are arranged outside the inner cavity 41; the size and thickness of the outer aluminum plate 1 are respectively the same as the size and thickness of the inner cavity 41; the sub-frame 4 and the outer aluminum plate 1 form an outer structure 7, and the size of the outer structure 7, the plastic plate 2 and the inner aluminum plate 3 are all the same, and the side edges of the outer structure 7, the plastic plate 2 and the inner aluminum plate 3 are all aligned; through the above three settings, the sub-frame 4 only needs to be connected to the outer aluminum plate 1, and at the same time, the gaps between the composite plates can be eliminated. This seamless docking design can improve the appearance quality of the curtain wall, making the overall look smoother and more beautiful.

[0089] Example 8

[0090] In this embodiment, a plurality of reinforcing ribs 8 are installed on the side of the inner aluminum plate 3 facing away from the outer aluminum plate 1, and the reinforcing ribs 8 are arranged in parallel and spaced apart.

[0091] The reinforcing ribs 8 each include a first reinforcing sub-rib 81 and a plurality of second reinforcing sub-ribs 82 connected to the first reinforcing sub-ribs 81 . The first reinforcing sub-ribs 81 and the second reinforcing sub-ribs 82 are both installed on the inner aluminum plate 3 .

[0092] Optionally, the reinforcing ribs 8 are made of an aluminum alloy profile that is the same as or similar to the aluminum plate.

[0093] The reinforcing ribs 8 are installed on the inner aluminum plate 3 to directly increase the rigidity of the inner aluminum plate 3. Although the reinforcing ribs 8 do not directly contact the outer aluminum plate 1, they indirectly affect the curtain wall composite panel as a whole by enhancing the rigidity and stability of the inner aluminum plate 3. This effect helps to reduce the deformation or vibration of the outer aluminum plate 1 under the influence of the external environment.

[0094] The second reinforcing sub-rib 82 is used in conjunction with the first reinforcing sub-rib 81 to expand the reinforcement range of the reinforcing rib 8 .

[0095] Optionally, the reinforcing ribs 8 form a grid structure.

[0096] Optionally, the reinforcing ribs 8 are installed on the inner aluminum plate 3 by a specific process (such as welding, riveting or bonding).

[0097] Example 9

[0098] In this embodiment, at least part of the edge portions of the outer aluminum plate 1 , the plastic plate 2 and the inner aluminum plate 3 are bent.

[0099] For example, taking the outer aluminum plate 1 as an example, any two ends of the outer aluminum plate 1 are symmetrically bent.

[0100] For example, taking the outer aluminum plate 1 as an example, the outer aluminum plate 1 is a square plate, and the edge of the outer aluminum plate 1 is bent to form four bending parts, and the four bending parts can be separated by cutting before bending.

[0101] The outer aluminum plate 1, the plastic plate 2 and the inner aluminum plate 3 are correspondingly bonded and connected at their bent parts.

[0102] By setting the above-mentioned bending parts, it can be regarded as that the curtain wall composite panel composed of the outer aluminum plate 1, the plastic plate 2 and the inner aluminum plate 3 has been folded. The folding treatment can solve the stress concentration phenomenon at the edge of the curtain wall composite panel. The stress originally concentrated on the edge can be dispersed to a larger area through folding, thereby reducing the risk of damage caused by excessive local stress. In addition, the edge of the curtain wall composite panel after folding forms a structure similar to a reinforcing rib. This structure can increase the supporting force of the curtain wall composite panel to a certain extent, making it more stable when facing external forces.

[0103] When installing the curtain wall composite panel, the bending direction of the bent portion is set toward the wall.

[0104] The bending angle of the bending portion is not specifically limited here.

[0105] When setting the bending portion, the sub-frame 4 needs to be adjusted accordingly. For example, the shape of the sub-frame 4 needs to be adjusted so as to fit the outer aluminum plate 1 .

[0106] Example 10

[0107] In this embodiment, the thickness of the outer aluminum plate 1 and the inner aluminum plate 3 are both smaller than the thickness of the plastic plate 2 .

[0108] Optionally, the outer aluminum plate 1 and the inner aluminum plate 3 are made of aluminum alloy plates with a thickness of 0.5mm to 1.0mm, which have good wind pressure resistance and corrosion resistance; the plastic plate 2 is made of high-strength and weather-resistant plastic materials, such as polyethylene (PE) or polyvinyl chloride (PVC), with a thickness of 2mm to 5mm.

[0109] Optionally, the thickness of both the outer aluminum plate 1 and the inner aluminum plate 3 is 1 mm; the thickness of the plastic plate 2 is 5 mm. The 1 mm thickness of the outer aluminum plate 1 provides good wind pressure resistance and corrosion resistance in general building environments, meeting the requirements of most indoor and general outdoor environments. The 5 mm thickness of the plastic plate 2 ensures its strength while providing a certain degree of protection against ultraviolet rays and adverse weather. Thicker plastic plates 2 generally provide better thermal and sound insulation, which is beneficial for improving the comfort and energy efficiency of buildings.

[0110] It should be noted that different application scenarios have different performance requirements for aluminum-plastic panels. For example, exterior curtain walls have higher requirements for the strength, weather resistance and decorativeness of aluminum-plastic panels, while interior decoration may focus more on aesthetics and lightness. Therefore, the specific needs of the application scenario need to be fully considered during design. In addition, the cost of aluminum-plastic panels is closely related to their thickness and material selection. On the premise of meeting performance requirements, reasonable cost control is also one of the factors that need to be considered during design. Based on this, the thickness and size of the outer aluminum plate 1, the inner aluminum plate 3 and the plastic plate 2 can be adjusted according to actual conditions.
