Description

Installation structure of curved decorative elements on building facade Technical Field

[0001] This utility model relates to the field of building exterior wall decoration, specifically to an installation structure for an arc-shaped decorative component on a building facade. Background Technology

[0002] To enhance the aesthetics of buildings, some existing buildings incorporate curved decorative elements on their exterior walls to meet diverse aesthetic demands. To fulfill design requirements, the applicant intends to install multiple spaced, elliptical-shaped curved column decorations on the building's facade. However, existing technologies often involve installing a single decorative element fixed to the exterior wall with a curved outer end. For example, Chinese Patent Application No. 2018100328283 discloses an exterior wall PU decorative structure and its construction method, comprising: a steel keel, including a main keel fixed to the exterior facade of the building's main structure by expansion bolts, secondary keels fixed to the main keel to form the desired shape, and supporting keels between the main keel and the secondary keels; a base plate fixed to the exterior surface of the secondary keel; and several PU decorative panels glued to the outer surface of the base plate and fixed to the secondary keel by self-tapping screws, the PU decorative panels being assembled into a single curved shape. The aforementioned structure, consisting of a cantilevered, curved decorative element with a curved outer surface, is unsuitable for installations of multiple spaced curved columns. Furthermore, while the PU board used in the aforementioned decorative panel is lightweight and easily bent, its gloss and strength are insufficient to meet the installation requirements of curved column decorations. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide an installation structure for curved decorative parts on building facades, which solves the problem that the existing curved decorative parts on building facades are integral and the decorative panels used have poor strength and gloss, and cannot meet the installation requirements of multiple curved column decorations.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An installation structure for curved decorative elements on a building facade includes a steel keel fixed to the main building structure. The steel keel includes multiple cantilever keels perpendicular to the upper end of the main building structure, a main keel connected to the outer end of the cantilever keels and arranged horizontally, and multiple curved decorative keels whose upper ends connect to the main keels and whose lower ends connect to the main building structure. Decorative aluminum panels enclosing the main keels and cantilever keels are fixedly installed on the main keels and cantilever keels. Multiple curved decorative keels enclosing the curved decorative keels are provided along their length. The decorative components consist of a first curved aluminum plate and a second curved aluminum plate, both with C-shaped cross-sections. The side panels of the first and second curved aluminum plates are positioned opposite each other and sealed at their ends. The inner walls of the side panels of both the first and second curved aluminum plates are fixedly connected to the arc-shaped decorative keel via connectors. At both the upper and lower ends of the first and second curved aluminum plates are clamping plates that engage with the arc-shaped decorative keel. The clamping plates of adjacent decorative components are tightly abutted and sealed. By setting multiple arc-shaped decorative keels, with the upper end connected to the main keel and the lower end connected to the building structure, the weight of the arc-shaped decorative keels is distributed between the main keel and the building structure, resulting in a stable installation structure. Furthermore, the decorative components covering each arc-shaped decorative keel are formed by connecting two C-shaped curved aluminum plates together, creating an elliptical cylindrical body. The curved aluminum panels used are high-strength, lightweight, and have a smooth surface, resulting in a good visual effect. The curvature of each decorative component along its length is customized in segments according to the design. The upper and lower end faces of the decorative components are attached to each other and fixedly connected. The curved aluminum panel in each decorative component is fixedly connected to the arc-shaped decorative keel through connectors. That is, the decorative components are connected to the arc-shaped decorative keel and to adjacent decorative components, so that the decorative components are mainly supported by the arc-shaped decorative keel. At the same time, the decorative components are sealed together, the structure is stable, and the overall sealing is good, preventing external impurities and water from entering.

[0006] Furthermore, the first and second curved aluminum plates are symmetrically arranged front and back. Both sides of the first and second curved aluminum plates are bent inwards to form a bonding plate. The bonding plates on corresponding sides of the first and second curved aluminum plates are sealed together with adhesive. In this way, the bending of both sides of the first and second curved aluminum plates, and the sealing of corresponding sides with adhesive, increases the contact and bonding area between the two sides. The adhesive sealing not only meets the sealing requirements but also connects the two curved aluminum plates together to form a single unit.

[0007] Furthermore, multiple L-shaped connecting plates are spaced apart on the inner walls of both the two laminated plates of the first curved aluminum plate and the two laminated plates of the second curved aluminum plate. The L-shaped connecting plates on the corresponding sides of the first and second curved aluminum plates are staggered and attached to the arc-shaped decorative keel, and are fastened to the arc-shaped decorative keel with screws. In this way, the L-shaped connecting plates can form a support between the L-shaped connecting plates and the arc-shaped decorative keel, and can also form a connector with the arc-shaped decorative keel together with the screws. The method of using L-shaped connecting plates to be tightly attached to the keel and then locked with screws is convenient to install and the structure is stable. At the same time, the staggered arrangement of the L-shaped connecting plates facilitates installation and fixation in confined spaces.

[0008] Furthermore, a strip hole is provided at the corresponding arc-shaped decorative keel of each L-shaped connecting plate. This allows the screws to move within the strip hole during installation, providing space for adjustment and movement.

[0009] Furthermore, both the cantilever keel and the main keel are constructed by welding and fixing multiple I-beams. Each cantilever keel and main keel has a steel frame that encloses it. The steel frame is welded and fixed to the main keel and to the cantilever keel via multiple connecting rods. The decorative aluminum panel is attached to the outside of the steel frame and connected to it via fasteners. This design requires higher strength than the curved decorative keel, and using I-beams as the cantilever keel and main keel meets their load-bearing requirements. The steel frame on the outside of the cantilever keel and main keel increases their dimensions, creating a spacious visual effect, and also forms multiple mounting surfaces on the outside of the I-beams, facilitating the installation and fixing of the aluminum panel.

[0010] Furthermore, the curved decorative keel consists of a single curved keel and multiple secondary keels. The curved keel is located at the lower end and is fixed to the secondary keels by welding. Adjacent secondary keels are also fixed by welding. Multiple pairs of connecting lugs, corresponding one-to-one with the curved decorative keel, are spaced apart at the lower end of the main keel. Each pair of connecting lugs forms a groove that mates with the upper end of the secondary keel. The secondary keels are then locked to the connecting lugs by connecting bolts. In this way, the curved decorative keel is constructed from multiple welded keels, facilitating transportation and reducing manufacturing difficulty. The connecting lugs on the main keel facilitate the fixed installation of the upper end of the curved decorative keel. Attached Figure Description

[0018] As shown in Figures 1-5, the installation structure of the curved decorative component on the building facade provided in this embodiment includes a steel keel fixed to the main body of the building. The steel keel includes multiple cantilever keels 1 perpendicular to the upper end of the main body of the building, a main keel 2 connected to the outer end of the cantilever keel 1 and arranged horizontally, and multiple curved decorative keels 4 whose upper ends are connected to the main keels 2 and whose lower ends are connected to the main body of the building (as shown in Figure 2, in this embodiment, the upper end of the curved decorative keel 4 is inclined outward, and the lower end is curved towards the main body of the building, with an elliptical cross-section). Decorative aluminum plates 5 covering the main keels 2 and cantilever keels 1 are fixedly installed on the main keels 2 and cantilever keels 1. Multiple decorative components 6 covering the curved decorative keels 4 are provided on each curved decorative keel 4 along the length direction of each curved decorative keel 4 (in this embodiment, each curved decorative keel 4 is provided with three decorative components 6). The decorative component 6 includes an upper decorative component, a middle decorative component, and a lower arc-shaped decorative component. The central axes of the upper and middle decorative components are straight, while the central axis of the lower arc-shaped decorative component is arc-shaped. Each decorative component 6 is custom-made in the factory according to the design dimensions. The decorative component 6 is composed of a first curved aluminum plate 61 and a second curved aluminum plate 62. The cross-sections of the first curved aluminum plate 61 and the second curved aluminum plate 62 are both C-shaped. The side plates of the first curved aluminum plate 61 and the side plates of the second curved aluminum plate 62 are arranged opposite to each other and their end faces are sealed together. The inner walls of the side plates of the first curved aluminum plate 61 and the side plates of the second curved aluminum plate 62 are fixedly connected to the arc-shaped decorative keel 4 through connectors. The upper and lower ends of the first curved aluminum plate 61 and the second curved aluminum plate 62 are provided with clamping plates 65 that are clamped together with the arc-shaped decorative keel 4. The clamping plates 65 of two adjacent decorative components 6 are tightly attached and sealed together. In this way, by setting up multiple curved decorative keels 4, with the upper end of the curved decorative keel 4 connected to the main keel 2 and the lower end connected to the main building structure, the weight of the curved decorative keel 4 is distributed between the main keel 2 and the main building structure, respectively, resulting in a stable installation structure. Meanwhile, the decorative components 6 covering each curved decorative keel 4 are composed of two curved aluminum plates connected together. The curved aluminum plates are C-shaped, and when two are connected together, they form a cylindrical body with an elliptical cross-section. The curved aluminum plates used are high-strength, lightweight, and have a smooth surface, resulting in a good visual effect. The curvature of each decorative component 6 along its length is customized in segments according to the design. The upper and lower end faces of each decorative component 6 are attached to each other and fixedly connected. The curved aluminum plate in each decorative component 6 is fixedly connected to the arc-shaped decorative keel 4 through connectors. That is, the decorative component 6 is connected to the arc-shaped decorative keel 4 and adjacent decorative components 6 are connected, so that the decorative component 6 is mainly supported by the arc-shaped decorative keel 4. At the same time, the decorative components 6 are sealed together, the structure is stable, and the overall sealing is good, so that no external impurities and water will enter.

[0019] As shown in Figure 1, both the cantilever keel 1 and the main keel 2 are welded and fixed together from multiple I-beams. Each cantilever keel 1 and main keel 2 is provided with a steel frame 3 that encloses it. The steel frame 3 is welded and fixed to the main keel 2 and to the cantilever keel 1 via multiple connecting rods. The decorative aluminum plate 5 is attached to the outside of the steel frame 3 and connected to it via fasteners. The arc-shaped decorative keel 4 consists of one arc-shaped keel and multiple secondary keels. The arc-shaped keel is located at the lower end and is welded and fixed to the secondary keels. Adjacent secondary keels are welded and fixed together. Multiple pairs of connecting lugs, corresponding one-to-one with the arc-shaped decorative keel 4, are spaced apart at the lower end of the main keel 2. Each pair of connecting lugs forms a groove that mates with the upper end of the secondary keel. The secondary keel and the connecting lugs are locked and fixed together with connecting bolts. Thus, the strength requirements for cantilever keel 1 and main keel 2 are higher than those for curved decorative keel 4. Using I-beams as cantilever keel 1 and main keel 2 can meet their load-bearing requirements. After installing steel frames 3 on the outside of cantilever keel 1 and main keel 2, the dimensions of cantilever keel 1 and main keel 2 are increased, giving them a spacious visual effect. Multiple mounting surfaces are also created on the outside of the I-beams, facilitating the installation and fixing of aluminum panels.

[0020] During installation, the I-beams, curved keels, and secondary keels are first transported to the construction site and welded according to the design dimensions to form cantilever keels 1, main keels 2, and curved decorative keels 4. Then, a crane is used to hoist the cantilever keels 1 and main keels 2 into place and weld them in place. Next, each curved decorative keel 4 is hoisted in sequence. After the keel installation is completed, the steel frame 3, decorative aluminum panels 5, and curved decorative components 6 are installed. In this embodiment, embedded parts are pre-embedded in the main building structure for welding and installation with the cantilever keels 1 and curved decorative keels 4. The cantilever keels 1 and curved decorative keels 4 are welded and fixed to the embedded parts, thus securing them to the main building structure.

[0021] As shown in Figures 3-5, the first curved aluminum plate 61 and the second curved aluminum plate 62 are symmetrically arranged front and back. Both sides of the first curved aluminum plate 61 and the second curved aluminum plate 62 are bent inwards to form a bonding plate 63. The bonding plates 63 on corresponding sides of the first curved aluminum plate 61 and the second curved aluminum plate 62 are sealed together with adhesive. In this way, the bending of both sides of the first curved aluminum plate 61 and the second curved aluminum plate 62, and the sealing of corresponding sides with adhesive, increases the contact area and bonding area on both sides of the first curved aluminum plate 61 and the second curved aluminum plate 62. The adhesive sealing not only meets the sealing requirements but also connects the two curved aluminum plates together to form a single unit.

[0022] Furthermore, multiple L-shaped connecting plates 64 are spaced apart on the inner walls of the two bonding plates 63 of the first curved aluminum plate 61 and the two bonding plates 63 of the second curved aluminum plate 62. The L-shaped connecting plates 64 on the corresponding sides of the first curved aluminum plate 61 and the second curved aluminum plate are staggered and attached to the arc-shaped decorative keel 4, and are fastened to the arc-shaped decorative keel 4 with screws. In this way, the L-shaped connecting plates 64 can form a support between themselves and the arc-shaped decorative keel 4, and can also form a connector with the arc-shaped decorative keel 4 together with the screws. The method of using L-shaped connecting plates to be tightly attached to the keel and then locked with screws is convenient to install and has a stable structure. At the same time, the staggered arrangement of the L-shaped connecting plates 64 can prevent interference between two adjacent L-shaped connecting plates 64. Of course, in specific implementation, the connecting cross plate of the L-shaped connecting plate 64 can be bent inward towards the first curved aluminum plate 61 or the second curved aluminum plate 62, which can also avoid interference between two L-shaped connecting plates 64 on the same side.

[0023] Furthermore, each L-shaped connecting plate 64 has a strip hole corresponding to the arc-shaped decorative keel 4. This allows the screws to move within the strip hole during installation, providing space for adjustment and movement.

[0024] In this embodiment, each decorative component 6 has a U-shaped latch on the first curved aluminum plate 61 and the second curved aluminum plate 62. The U-shaped latch is tightly engaged with the corresponding arc-shaped decorative keel 4. The two U-shaped latches are arranged correspondingly, and after the side ends are tightly attached, a rectangular opening is formed that cooperates with the arc-shaped decorative keel 4.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
