[0016] like Figures 1 to 7 As shown, a large decorative line structure for a curtain wall includes a steel plate assembly 2 connected to a steel structure column 1. A main support keel assembly is provided at the end of the steel plate assembly 2 away from the steel structure column 1. The main support keel assembly includes a large decorative beam 3 with a core insert 8. A sealing plate 4 is provided at the transverse end of the large decorative beam 3, and the sealing plate 4 is connected to the steel plate assembly 2. A glass pressure plate 5 is connected to the side of the large decorative beam 3 near the steel structure column 1. Installation grooves are formed above and below the glass pressure plate 5 and the large decorative beam 3, respectively. These installation grooves are used to install curtain wall glass 6. A sealing connection assembly is also provided between adjacent curtain wall glass 6.

[0017] The large decorative lines of this curtain wall, through the use of the steel plate components and the improvement of the main support keel components, make the connection between the support keel and the steel structure columns of the main structure more reliable and stable, less prone to stress concentration problems, and also improve the overall wind pressure resistance and deformation resistance of the lines.

[0018] The steel plate assembly 2 and the main support keel assembly can solve the processing problem of large-size lines through component disassembly and customized processing, adapt to complex shape requirements, reduce the difficulty of transporting and hoisting scattered parts, and improve the flexibility of on-site installation. These components can be assembled on the construction site, shortening the processing and installation cycle (the overall cycle is shortened by 40% compared with the traditional process).

[0019] The large decorative beam 3 is not only a major component of the large decorative line, but also supports the installation of the curtain wall glass 6. With the cooperation of the glass pressure plate 5, it can stably connect the curtain wall glass 6 and ensure safety.

[0020] The sealing plate 4 serves as a connector and can also seal the end opening of the large decorative beam 3 to prevent rainwater from entering. In conjunction with the sealing connection assembly, it can improve the sealing and thermal insulation performance of the curtain wall to meet the thermal and waterproof requirements of high-energy-saving buildings.

[0021] Furthermore, the steel plate assembly 2 includes a steel plate frame 201 connected to the steel structure column 1. A connecting steel plate 202 is provided on the side of the steel plate frame 201 away from the steel structure column 1. The connecting steel plate 202 is connected to the sealing plate 4 by multiple bolts. The interior of the steel plate frame 201 is used to install a downpipe 7.

[0022] The steel plate frame 201 is welded from multiple steel plates. The connecting steel plate 202 is welded to the steel plate frame 201 and is also welded to the steel structure column 1. This connection method can ensure the connection stability and strength of the steel plate assembly 2. The welding operation of the steel plate assembly 2 can be completed during the construction of the steel structure column 1 or before the installation of the decorative lines.

[0023] The sealing plate 4 is connected to the connecting steel plate 202 by a number of stainless steel high-strength bolts, which facilitates assembly and real-time adjustment. Sealing plates 4 are provided on both sides of the connecting steel plate 202, and two adjacent sealing plates 4 can be connected and fixed simultaneously using stainless steel high-strength bolts.

[0024] The steel plate frame 201 is not only used to connect and install steel structure columns and large decorative beams, but also allows the downpipe 7 to pass through its internal space, which facilitates the arrangement of downpipes from top to bottom, so as to facilitate drainage of the building structure in the later stage.

[0025] Furthermore, in combination Figure 4 As shown, the large decorative beam 3 includes a decorative beam part 301 with a design. The side end face of the decorative beam part 301 is provided with a beam connecting part 302. The decorative beam part 301 is provided with the insert 8. The beam connecting part 302 connects to the glass pressure plate 5 and forms the mounting groove.

[0026] The decorative section 301 of the beam can form the required decorative structure on the outdoor side. The beam connecting section 302 can be used to connect the glass pressure plate 5 and the curtain wall glass 6. The insert 8 is provided to connect the sealing plate 4, so that the large decorative beam 3 can be connected to the steel plate assembly 2 to form an overall support frame.

[0027] Specifically, the thickness of the beam decorative part 301 decreases from the side closest to the curtain wall glass to the side furthest from the curtain wall glass, and the upper surface is inclined. The interior of the beam decorative part 301 is provided with an inner partition 303, which divides the interior into a large inner cavity 3011 and a small inner cavity 3012. The insert 8 includes a large insert 801 located at the port of the large inner cavity 3011 and a small insert 802 located at the port of the small inner cavity 3012. The large insert 801 is located in the large inner cavity 3011 and is connected to the large inner cavity through a self-tapping screw 9. The small insert 802 connects the small inner cavities 3012 of two adjacent large decorative beams.

[0028] The large inner cavity 3011 occupies more than 70% of the internal space of the crossbeam decorative part. Larger inserts 801 can be set at both ends. The large inserts 801 can increase the structural strength at both ends and facilitate the connection of the sealing plate 4. The two ends of the small inserts 802 can be inserted into two adjacent small inner cavities 3012 respectively, which can further connect the adjacent crossbeam decorative parts and help improve the integrity and stability of the line structure.

[0029] Furthermore, the inner circumference of the large insert 801 is provided with several connecting grooves 10, and the sealing plate 4 is connected to the connecting grooves 10 by countersunk screws 11. This connection method is simple, stable, and avoids screws protruding outwards. The length of the sealing plate 4 is greater than the longitudinal length of the large decorative beam 3, that is, its width, so that it can extend out of the large decorative beam 3 to connect with the connecting steel plate 202 located on the indoor side.

[0030] Furthermore, in combination Figure 6 As shown, a rubber sheet 12 is provided between the sealing plate 4 and the connecting steel plate 202 of the steel plate assembly, and a caulking sealant 13 is also provided between the sealing plate 4 and the end face of the large decorative beam 3. The ends of the sealing plates 4 adjacent to the large decorative beam 3 are also connected to end sealing plates 16, which serve both as a connection and as a means to seal adjacent sealing plates.

[0031] The rubber sheet 12 and the caulking sealant 13 not only improve the sealing performance between the sealing plate 4, the connecting steel plate 202, and the large decorative beam 3, preventing water seepage, but also provide heat insulation, reducing heat exchange between these metal parts and improving the building's thermal insulation performance.

[0032] Furthermore, the end face of the crossbeam connecting part 302 is provided with a bolt connecting groove, and is connected to the glass pressure plate 5 through the bolt group 14. A continuous nylon heat insulation strip 15 is also provided between the crossbeam connecting part 302 and the glass pressure plate 5.

[0033] This setup allows for better installation and fixation of the curtain wall glass 6. The outer periphery of the curtain wall glass 6 is provided with sealant and foam rods between it and the crossbeam connection 302, which can play a role in sealing and heat insulation. Sealing strips are also provided on both sides of the curtain wall glass 6, and weather-resistant sealant is also provided on the outdoor side, which can ensure the stability and sealing of the curtain wall glass connection and installation.

[0034] The nylon heat insulation strip 15 can block the heat exchange between the large decorative beam 3 and the glass pressure plate 5, thus playing a heat insulation role.

[0035] Furthermore, such as Figure 7 As shown, the sealing connection assembly includes a glass edge 17 connected to the end of the curtain wall glass 6. The inner circumference of the glass edge 17 is bonded to the end face of the curtain wall glass 6 by structural adhesive 18. A first sealing strip 19 is provided between the glass edge 17 and the side of the curtain wall glass 6. A second sealing strip 20 is connected between adjacent glass edges 17. Weather-resistant sealant 21 is also provided on the outdoor side of the second sealing strip 20.

[0036] The glass edge protector 17 not only protects the outer perimeter of the curtain wall glass 6, but also serves as a connector. Through the setting of the first sealing strip 19 and the second sealing strip 20, a multi-layer sealing and waterproof structure can be formed. A sealing strip is set at the junction of the main support keel and the glass, and weather-resistant sealant is applied to the outside of the strip to form a double-layer seal of "strip + sealant". This can ensure waterproof and airtight performance, work in synergy with the overall performance of the curtain wall, and extend the service life of the lines.

[0037] The glass edge protector 17 is provided with a rubber strip connecting groove. The inner side and both ends of the second sealing rubber strip 20 are respectively provided with insertable edge strips. The insertable edge strip near the middle can be inserted into the rubber strip connecting groove, and the two ends can be inserted between the glass edge protector and the curtain wall glass to form a firm connection and sealing structure.

[0038] In this embodiment, the large decorative beam 3, the glass pressure plate 5, the sealing plate 4, and the glass edge protector 17 are all aluminum alloy structural components, and their surfaces are all coated with a wear-resistant and corrosion-resistant coating. The first sealing strip, the second sealing strip, and the sealing strips at other locations are all made of EPDM rubber.

[0039] In some implementations, stainless steel hangers are also provided on the concrete structure at the top of the main building structure. The stainless steel hangers can pass vertically through the gap between adjacent curtain wall glass. The lower end of the stainless steel hangers can be connected to the beam connection part of the large decorative beam. The installation of the stainless steel hangers is coordinated with the adjustment of the hanger length so that the horizontal error of the main keel assembly is ≤1mm / m.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
