[0018] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0019] The following will describe in detail some implementation manners of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0020] Refer to Figures 1 to 6 , a large-span assembled decorative line, including an assembled keel structure, the assembled keel structure is arranged on the vertical curtain wall keel 20, the vertical curtain wall keel 20 is arranged on the fixed installation part 23 through the stiffener 19, a curtain wall embedded part 21 is further arranged between the vertical curtain wall keel 20 and the stiffener 19, and a vertical keel support 22 is further arranged on the curtain wall embedded part 21; a variety of decorative components are further arranged on the assembled keel structure, and the decorative components include aluminum plates and grille lines.

[0021] In this embodiment, the prefabricated keel structure includes unit components 4, top keel components and bottom keel components. The top keel components include a first transverse keel 1 and a second transverse keel 2 arranged in parallel. The first transverse keel 1 and the second transverse keel 2 are respectively arranged at both ends of the top opening of the unit component 4. A horizontal keel 5 is also arranged between the first transverse keel 1 and the second transverse keel 2. The bottom keel component includes a third transverse keel 3, and the third transverse keel 3 is arranged at the bottom of the unit component 4.

[0022] In this embodiment, the unit component 4 includes a first vertical keel 6 and a second vertical keel 7. The length of the first vertical keel 6 is greater than that of the second vertical keel 7. The top of the first vertical keel 6 is connected to the top of the second vertical keel 7 through the horizontal keel 5. The bottom of the first vertical keel 6 is connected to the bottom of the second vertical keel 7 through an arc keel 11. And a brace 12 is also arranged between the arc keel 11 and the first vertical keel 6. The first vertical keel 6, the second vertical keel 7, the brace 12 and the arc keel 11 are formed by welding. Further, a first support leg 8 is arranged at the lower end tail of the first vertical keel 6. A second support leg 9 is arranged at the upper end tail of the first vertical keel 6. The first vertical keel 6 is located at the back of the prefabricated keel structure and is an important part of the vertical components of the unit component 4. It can be cut from a galvanized square pipe according to the actual required length. It is welded at the upper end to the horizontal keel 5 and at the lower end to the first support leg 8. A first clamping member 13 and a second clamping member 14 for fixing the prefabricated skeleton are respectively welded at the upper end and the lower end of the first vertical keel 6 to realize the fixation of the entire decorative grille keel. The second vertical keel 7 is located at the front section of the prefabricated keel structure and is also an important part of the vertical components of the unit component 4. It can be cut from a galvanized square pipe according to the actual required length. It is fixed to the horizontal keel 5 by full welding and is connected to the arc keel 11 by full welding at the lower end to form a stable unit keel skeleton. At the same time, this second vertical keel 7 can provide an installation and fixation foundation for the decorative lines of the skin.

[0023] The arc-shaped keel 11 is located between the horizontal keel 5 and the first vertical keel 6, and is fixed to the horizontal keel 5 and the first vertical keel 6 respectively by welding, forming the outer keel system of the unit component of the decorative line. And by using this arc-shaped keel, the arc-shaped shape is realized, changing the single shape of the decorative grille, making the decorative grille line more beautiful. This arc-shaped keel 11 can be processed from galvanized square tubes according to the designed shape by using professional bending machinery. When the arc-shaped curved surface is relatively large, a professional processing factory can be used to directly process and form the arc during the production of galvanized square tubes. The brace 12 is located in the middle of the unit component 4 and can connect the arc-shaped keel 11, the first vertical keel 6 and the horizontal keel 5 by welding, improving the stability and firmness of the unit component 4 and preventing the triangular structure formed by the first vertical keel 6, the horizontal keel 5 and the arc-shaped keel 11 from deforming under the action of a large external force.

[0024] In this embodiment, a first support leg 8 is provided at the lower end tail of the first vertical keel 6; a second support leg 9 is provided at the upper end tail of the first vertical keel 6. Specifically, the first support leg 8 can be fixed to the bottom of the first vertical keel 6 by welding. This first support leg 8 can be cut from a galvanized square tube and can provide an installation foundation for the bottom sealing decorative aluminum plate, such as being connected to the channel steel 10, etc., ensuring the decorative beauty and integrity, and avoiding decorative defects caused by the complete closure of the area between the keel body structure and the main structure. The second support leg 9 can be fixed to the upper part of the first vertical keel 6 by welding. This first vertical keel 6 can be cut from a galvanized square tube and provides an installation foundation for the top sealing decorative aluminum plate, ensuring the decorative beauty and integrity, and avoiding decorative defects caused by the inability of the keel structure to completely close the area between the keel structure and the main structure. The first clip 13, the second clip 14, the first support leg 8 and the second support leg 9 can be fixed to the first vertical keel 6 by welding to form a complete unit component. The first vertical keel 6 is fixed to the curtain wall vertical keel 20 through the first clip 13 and the second clip 14. Bolts 15 are provided on both the first clip 13 and the second clip 14. The first clip 13 and the second clip 14 are respectively arranged on the first fixed support 16 and the second fixed support 17 through the bolts 15, and the assembled installation of the assembled keel structure is realized through the first fixed support 16 and the second fixed support 17. The bolt 15 is a screw with a thread and a screw, which cooperates with the reserved threaded holes on the clips (the first clip 13 and the second clip 14) to fasten the clips to the reverse sides of the angle steel clips on the fixed supports (the first fixed support 16 and the second fixed support 17), further realizing the fixation of the large-span decorative keel structure and preventing overturning under the action of gravity or during secondary decoration, providing the safety and stability of the assembled line.

[0025] Specifically, the shape of the first card member 13 is similar to an irregular rectangular plate. There is a matching stud fixing thread structure on the side, and there is a notch at the lower part to match with the angle steel card member on the first fixing support 16 to achieve matching, so as to realize the assembled installation. This first card member 13 is located at the upper end of the first vertical keel 6. By using the cooperation of the first card member 13 and the first fixing support 16, the fixation of the upper part of the large-span assembled keel structure is realized, and the assembled installation of the assembled keel framework is realized in cooperation with the second card member 14. Further, the structural configuration of the second card member 14 is the same as that of the first card member 13, only the position is different; this second card member 14 is located at the lower end of the first vertical keel 6. By using the cooperation of the second card member 14 and the second fixing support 17, the fixation of the lower part of the large-span assembled keel structure is realized, and the assembled installation of the assembled keel framework is realized in cooperation with the first card member 13.

[0026] In this embodiment, the first horizontal keel 1 is located at the upper part of the keel structure. Through the mutual cooperation of the first horizontal keel 1, the second horizontal keel 2, and the third horizontal keel 3, the unit components 4 of the entire keel framework can be connected, thus forming a complete keel system, providing a support and fixing foundation for the installation of the decorative surface layer. This first horizontal keel 1 can be cut from a galvanized rectangular pipe and fixed to the top of the first vertical keel 6 by welding to ensure the stability of the upper keel structure. It can be conceived that when it is in the horizontal section, this first horizontal keel 1 is a horizontal framework, and when it is in the corner area, this first horizontal keel 1 is a curved structure, so as to realize the installation of the keel frameworks of the decorative grille lines for both straight and curved sections. The second horizontal keel 2 is located at the front end of the keel structure. Through the mutual cooperation of this second horizontal keel 2 with the first horizontal keel 1 and the third horizontal keel 3, the unit components 4 of the entire keel framework can be connected, thus forming a complete keel system, providing a support and fixing foundation for the installation of the decorative surface layer. This second horizontal keel 2 can be cut from a galvanized rectangular pipe and fixed to the upper part of the second vertical keel 7 by welding to ensure the stability of the front decorative line keel structure. When it is in the horizontal section, this second horizontal keel 2 is a horizontal framework, and when it is in the corner area, this second horizontal keel 2 is a curved structure, so as to realize the installation of the keel frameworks of the decorative grille lines for both straight and curved sections. The third horizontal keel 3 is located at the bottom of the keel structure. Through the mutual cooperation of this third horizontal keel 3 with the first horizontal keel 1 and the second horizontal keel 2, the unit components 4 of the keel structure can be connected, thus forming a complete keel system, providing a support and fixing foundation for the installation of the decorative surface layer. This third horizontal keel 3 can be cut from a galvanized rectangular pipe and fixed to the upper part of the first vertical keel 6 by welding to ensure the stability of the bottom decorative line keel structure. When it is in the horizontal section, this third horizontal keel 3 is a horizontal framework, and when it is in the corner area, this third horizontal keel 3 is a curved structure, so as to realize the installation of the keel frameworks of the decorative grille lines for both straight and curved sections.

[0027] In this embodiment, when the installed main structure is a steel structure, the fixed mounting member 23 is an I-shaped steel beam. The I-shaped steel beam is an important part of the main steel structure and is located at the edge of the building with the main steel structure. Generally made of I-shaped steel, it can provide an installation and fixing foundation for the installation of the stiffening rib 19. It should be noted that when the main structure is a reinforced concrete structure, this structure is not involved, that is, the concrete surface is used as the installation and fixing support for the fixed support. The stiffening rib 19 is located between the I-shaped steel beam and the curtain wall embedded part 21 and is made of multiple rectangular steel plates with a certain thickness and strength. In the form of full welding, the stiffening rib is first welded to the I-shaped steel beam to solve the problem that the curtain wall embedded plate cannot take root, and then provides an installation and fixing foundation for the curtain wall embedded plate. The curtain wall embedded part 21 is located on the surface of the stiffening rib 19 and is in the shape of a rectangular or square steel plate with a certain strength and thickness. It is fixed to the stiffening rib 19 by welding to provide an installation and fixing foundation for the fixing of the curtain wall vertical keel support.

[0028] When the installed main structure is a concrete structure, the fixed mounting member 23 is the structural surface, which is used when the main structure does not adopt a steel structure main body or when the support surface of the curtain wall support is not located at the steel structure position. It is cast with steel bars and concrete with a certain strength to provide a fixed foundation for the support of the curtain wall vertical keel.

[0029] In this embodiment, the vertical keel support 22 is located on the reinforced concrete structural surface or the curtain wall embedded part 21. Generally cut from galvanized channel steel, a long strip hole is opened horizontally on the channel steel 10 of the support to provide an installation and fixing base for the tie bolts for fixing the curtain wall vertical keel 20, and provide a fixed foundation for the installation of the curtain wall vertical keel through the vertical keel support.

[0030] In this embodiment, the decorative component includes a horizontal aluminum plate 24, an arc aluminum plate 28 and a bottom aluminum plate. The horizontal aluminum plate 24, the arc aluminum plate 28 and the bottom aluminum plate are respectively arranged on the assembled keel structure through blind rivets 32. Specifically, the horizontal aluminum plate 24 is located in the upper horizontal direction of the assembled keel structure and plays a decorative role at the top. Its appearance size and color are determined according to the design. It is fixed on the second U-shaped aluminum alloy part 30 and the third U-shaped aluminum alloy part 31 through blind rivets 32 to realize the fixation of the front end and the tail end of the top aluminum plate, thus ensuring the flatness of the surface. The arc aluminum plate 28 is located in the lower arc direction of the assembled keel structure and plays a decorative role at the top. Its appearance size and color are determined according to the design. It is fixed on the first U-shaped aluminum alloy part 29 and the second U-shaped aluminum alloy part 30 through blind rivets 32 to realize the fixation of the front end and the tail end of the arc aluminum plate, and a fixing part for the aluminum plate is used to fix the middle part of the arc aluminum plate, thus ensuring the firm fixation of the whole arc aluminum plate and the decorative effect of the whole arc aluminum plate. The bottom aluminum plate is located at the bottom of the first support leg 8 of the assembled keel structure and is fixed on the first U-shaped aluminum alloy part 29 through blind rivets 32 to realize the edge sealing and closing treatment at the bottom position of the large-span assembled decorative line.

[0031] Furthermore, in order to fix the aluminum plate, a fixing part for the aluminum plate is also provided. This fixing part for the aluminum plate is a finished component, and the spacing is evenly arranged according to the length of the arc section of the decorative line. In principle, there are no less than 2 groups in a single cross-section. The fixing part for the aluminum plate is fixed on the arc keel of the large-span assembled keel structure through self-tapping screws, and then the arc aluminum plate is fixed by using blind rivets, thus ensuring the stability and safety of the installation of the arc aluminum plate, preventing deformation and falling off in the middle, and affecting the decorative effect of the arc aluminum plate. Specifically, weather-resistant sealant is also provided. By using this weather-resistant sealant, the joints generated by the splicing between the top aluminum plate, the arc aluminum plate and the bottom aluminum plate are caulked to ensure the sealing performance of the caulked position, thereby improving the durability of the decorative line.

[0032] In this embodiment, the decorative component includes a first grille line 25, a second grille line 26 and a third grille line 27. Among them, the first grille line 25 is located at the top position of the upper cornice of the assembled keel structure and corresponds to the second grille line 26, forming a double-line structure of the upper cornice. It is fixed at the intersection position of the top aluminum plate and the arc aluminum plate through blind rivets 32, playing a role in enhancing the line decoration, changing the single structure of the large-span assembled decorative line, and making it more beautiful and ornamental. This grille line is processed from aluminum alloy and is composed of an aluminum alloy card seat and an aluminum alloy decorative strip. The aluminum alloy card seat is divided into two upper and lower card slots. A screw is fixed at the top of the aluminum alloy decorative strip stuck in it to prevent the decorative strip from sliding (the structures of the first grille line 25, the second grille line 26 and the third grille line 27 are the same, and will not be elaborated below).

[0033] The second grille line 26 is located at the bottom position of the upper eaves of the assembled keel structure and corresponds to the first grille line 25, forming a double-line structure of the upper eaves. It is fixed at the straight corner section of the arc-shaped aluminum plate 28 by blind rivets. There is a lamp slot and a light strip in the middle, thus providing an installation basis for the lighting project and enhancing the decorative lighting effect between the first grille line 25 and the second grille line 26.

[0034] The third grille line 27 is located at the lower end position of the assembled keel structure and is fixed on the first U-shaped aluminum alloy part 29 at the bottom end of the arc-shaped aluminum plate 28 by blind rivets. There is a lamp slot and a light strip in the middle of the third grille line 27, thus providing an installation basis for the lighting project and enhancing the decorative lighting effect of the arc-shaped aluminum plate section. This grille line is made of aluminum alloy and is set into an upper and lower snap structure, and the closure is directly achieved by using the matching snaps.

[0035] In this embodiment, a second decorative slot 34 is provided on the second grille line 26, and a first decorative slot 33 is provided on the third grille line 27. Both the second decorative slot 34 and the first decorative slot 33 are decorative lamp slots and light strips, specifically located in the middle of the surfaces of the first grille line 25 and the second grille line 26. An LED light strip is reserved in a concave slot to achieve the quantification project, and the lighting effect is increased through the light strip, further enhancing the overall decorative effect of the building facade.

[0036] Regarding the construction of the present invention, it should be noted that considering the large-span assembled decorative line is large-span and extra-long, in order to avoid completely processing the grille in the factory and transporting it to the construction site, which may cause deformation and damage to the decorative aluminum plate and line on the surface layer during transportation, the large-span assembled keel structure is processed in the factory and transported to the construction site for assembly construction, or processed into a unit support form and transported to the construction site for assembly, and then a special hoisting device is used for hoisting. Therefore, the surface layer decorations such as the horizontal aluminum plate, arc-shaped aluminum plate, grille line, decorative lamp slot and light strip involved in the present invention need to be installed on-site after the on-site assembly construction of the large-span assembled keel structure is completed.

[0037] Specifically, the construction process of the present invention includes: Step 1: Processing of prefabricated keel components. According to the design requirements of the long-span prefabricated keel structure, use BIM technology to obtain the corresponding processing parameters of the first clip 13, the second clip 14, the stud 15, the first vertical keel 6, the second vertical keel 7, the diagonal brace 12, the arc keel 11, the first support leg 8, and the second support leg 9, and complete the cutting and blanking of the corresponding components; when factory assembly is adopted, complete the long-span prefabricated keel structure according to the design drawings and make numbers for convenient transportation to the construction site for assembly. When it is convenient to transport by assembling into unit brackets, it is necessary to make numbers and classify each part of the components for convenient transportation to the construction site to complete the final assembly of the long-span prefabricated keel structure.

[0038] Step 2: Transportation or assembly. Transport the long-span prefabricated keel structure or related components of the long-span prefabricated keel structure processed in the factory to the construction site, and do a good job in finished product protection to prevent damage and deformation. If the prefabricated keel structure is assembled on-site, after the relevant accessories are transported to the construction site, it is also necessary to complete the assembly of each unit of the long-span prefabricated keel structure according to the assembly drawings extracted by BIM.

[0039] Step 3: Measuring and setting out. According to the installation positions required for the designed long-span prefabricated decorative lines, use an electronic laser theodolite in cooperation with a tape measure, paint, etc. to mark the positions where the decorative line supports, keels, and lines need to be installed, providing a support foundation for the next installation.

[0040] Step 4: Support installation. When the main body is a steel structure, adopt the welding form to directly weld the stiffening ribs on the I-beam to provide an installation foundation for the curtain wall embedded plate installation. Then, fix the support for the vertical keel of the curtain wall on the channel steel support supported by the curtain wall embedded plate by using a tie rod bolt, and use the strip holes on the channel steel to adjust the error. It should be noted that when the main structure is a reinforced concrete structure, use a post-embedded plate to install the support for the vertical keel of the curtain wall, and then use bolts to fix the first vertical keel. After completing the installation of the vertical keel of the curtain wall, use the fixed support described in the patent to install the fixed support on the vertical keel of the curtain wall by using a tie rod bolt, providing an installation and fixing foundation for the installation of the prefabricated keel.

[0041] Step 5: Installation of prefabricated keel. After the above support installation is completed, use a special lifting device to lift the long-span prefabricated keel structure assembled in the factory or on-site in advance to the position where it needs to be installed. After verifying that the position is correct, use the first clip 13 and the second clip 14 to fix the prefabricated keel, and use the studs attached to the clips to strengthen the fixation of the prefabricated keel to prevent overturning.

[0042] Step 6: Install aluminum alloy parts and aluminum plate fixings. According to the design drawings, use self-tapping screws to complete the installation and fixing of the first U-shaped aluminum alloy part 29, the second U-shaped aluminum alloy part 30, the third U-shaped aluminum alloy part 31, and the aluminum plate fixings, providing a foundation for the installation and fixing of the decorative aluminum plate in the next step.

[0043] Step 7: Install the decorative aluminum panels. Use blind rivets to install the top aluminum panel, curved aluminum panel, and bottom aluminum panel in sequence. When installing the curved aluminum panel, use aluminum panel fixings to improve the stability of the installation and prevent deformation and dislocation of the curved aluminum panel.

[0044] Step 8: Install the decorative grille lines. Use blind rivets and self-tapping screws to install the first grille line 25, the second grille line 26, and the third grille line 27 from top to bottom. During the installation process, ensure that the first grille line 25, the second grille line 26, and the third grille line 27 are horizontally spliced to ensure accuracy.

[0045] Step 9: Glue and seal. After installing the decorative aluminum panels and decorative grille lines, in order to ensure the sealing of the installation joints, it is necessary to use weather-resistant sealant of the same color or a similar color to glue and seal the joints of each accessory. When applying the glue, make sure it is horizontal and vertical.

[0046] Step 10: Light strip installation. After completing the above steps, install LED light strips or light bars in the light grooves reserved on the decorative grille lines to ensure the lighting effect. The power supply and controller positions involved in the light strips need to be designed and reserved in advance when installing the line grille to ensure the final molding effect.

[0047] Based on the above embodiments, the present invention has at least the following technical effects: The present invention solves the technical difficulties in the design and construction of the assembled structure of large-span decorative lines on the facade of the curtain wall.
