[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0034] As attached Figure 1-5 As shown, the sliding semi-assembled multi-faceted curtain wall system of the present invention includes side columns 1, central columns 2, channel steel adapters 3, steel beams 5, aluminum glass channels 6, and glass panels 7.

[0035] Two side columns 1 are provided, and the two side columns 1 are symmetrically arranged on both sides of the central column 2. One end of the channel steel adapter 3 is connected to the side column 1, and the other end is connected to the main building 8 to realize the connection between the curtain wall system and the main building 8.

[0036] In this embodiment, a horizontal elongated hole 31 is provided on the channel steel adapter 3, and an adjusting bolt 32 is inserted into the horizontal elongated hole 31. The adjusting bolt 32 cooperates with the horizontal elongated hole 31 to adjust the front and rear position of the side column 1, so as to reduce errors and improve installation accuracy.

[0037] One end of the steel beam 5 is connected and fixed to the side column 1, and the other end is connected and fixed to the middle column 2. In this embodiment, the steel beam 5 is connected and fixed to the side column 1 by a transition steel part 9, and the other end is fixed to the middle column by welding. Of course, commonly used bolts, angle brackets and other components in the art can also be used to connect the steel beam 5 and the middle column 2.

[0038] Furthermore, an aluminum back panel 51 is provided on the rear side of the steel beam 5. The two ends of the aluminum back panel 51 are respectively connected and fixed to the adjacent side columns 1, which serves to shield the central column 2 and the steel beam 5, making the curtain wall appearance more neat.

[0039] As attached Figure 1 ,3 As shown, a sliding cavity 11 is provided on the side of the side column 1 near the middle column 2. The glass channel aluminum 6 is slidably disposed in the sliding cavity 11 and is positioned and connected to the side column 1 by countersunk screws. The glass channel aluminum 6 has a mounting groove 61. One end of the glass panel 7 is inserted into the mounting groove 61 of the glass channel aluminum 6, and sealant is applied to both sides of the glass panel 7 to improve the sealing and waterproofing effect. The other end of the glass panel 7 is connected and fixed to the outside of the middle column 2. Specifically, a glass sub-frame 21 is fixedly disposed on the outside of the middle column 2, and the glass panel 7 is fixed to the glass sub-frame 21 by two-component structural adhesive. A second aluminum alloy inner pressure plate 211 is fixedly disposed on the glass sub-frame 21, and the second aluminum alloy inner pressure plate 211 presses the glass panel 7 from the outside. A decorative cover plate 212 is fixedly disposed on the outside of the second aluminum alloy inner pressure plate 211.

[0040] By designing a sliding cavity 11 on the side column 1, the molding requirements of different entry and exit surfaces can be achieved using a uniform column profile mold, which greatly reduces the amount of mold required. At the same time, the groove cooperation between the glass panel 7 and the glass groove aluminum 6 allows the molding surface to be gradually adjusted back and forth, and also keeps the glass panel 7 under uniform force. This avoids the problems of frequent disassembly and assembly of the glass panel 7 during the positioning process and the problem of uneven force on the edge of the glass panel 7 due to the problem of tilting back and forth, which can lead to spontaneous breakage and damage.

[0041] The glass groove aluminum 6 divides the sliding cavity 11 on the side column 1 into two cavities. The inner and outer sides of the glass groove aluminum 6 are respectively provided with a first vertical decorative frame 62 and a second vertical decorative frame 63. The first vertical decorative frame 62 closes the cavity located inside the glass groove aluminum 6, and the second vertical decorative frame 63 closes the cavity located outside the glass groove aluminum 6.

[0042] Specifically, slots 64 are provided on both sides of the glass channel aluminum 6. One end of the first vertical decorative frame 62 is inserted into the slot 64 inside the glass channel aluminum 6, and the other end of the first vertical decorative frame 62 is snapped onto the side column 1. A first aluminum alloy inner pressure plate 12 is provided on the outer end of the side column 1. One end of the second vertical decorative frame 63 is inserted into the slot 64 outside the glass channel aluminum 6, and the other end of the second vertical decorative frame 63 is fixed to the side column 1 by the first aluminum alloy inner pressure plate 12.

[0043] Furthermore, a reinforcing steel pipe 13 is fixedly installed inside the cavity located on the inner side of the aluminum glass tank 6. The reinforcing steel pipe 13 is fixed inside the column by countersunk screws, which enhances the structural strength of the side column 1.

[0044] Furthermore, an exterior decorative element 121 is fixedly installed on the outer side of the first aluminum alloy inner pressure plate 12, and an aluminum alloy sealing plate 122 is snapped onto the inner side of the exterior decorative element 121. The aluminum alloy sealing plate 122 is used to close the gap between the first aluminum alloy inner pressure plate 12 and the exterior decorative element 121, and the outer side of the aluminum alloy sealing plate 122 is flush with the outer side of the second vertical decorative frame 63 to ensure the consistency of the curtain wall appearance.

[0045] In this embodiment, the side column 1 is provided with a first steel core 14 inside, which is used to connect and fix the adjacent side columns 1 above and below; the middle column 2 is provided with a second steel core 22 inside, which is used to connect and fix the adjacent middle columns 2 above and below; thereby completing the connection between the adjacent side columns 1 and the middle column 2 above and below, and improving the structural strength of the side columns 1 and the middle column 2, making the curtain wall system more stable.

[0046] The present invention also provides a construction method for the above-mentioned sliding semi-prefabricated multi-faceted curtain wall system, comprising the following steps:

[0047] S1. Fix the channel steel adapter 3 to the prefabricated embedded part of the building body 8 by welding; ensure the welding quality and ensure that the channel steel adapter 3 is firmly connected to the building body 8, so as to provide a stable foundation for the subsequent installation of the side column 1.

[0048] S2. In the workshop, pre-drill approximate positioning holes for the finished surface of the glass panel 7 in the sliding cavity 11 of the side column 1. Then, place the glass groove aluminum 6 into the sliding cavity 11, slide and adjust the position of the glass groove aluminum 6 and fix it. The cut first vertical decorative frame 62 and second vertical decorative frame 63 are respectively snapped onto both sides of the glass groove aluminum 6 to seal the sliding cavity 11 and ensure that the sliding cavity 11 is well sealed. Then, fix the reinforcing steel pipe 13 in the inner cavity for reinforcement, complete the overall assembly of the side column 1, and then transport it to the construction site.

[0049] The side column 1, which is assembled as a whole, is processed and assembled in the workshop, which can improve the assembly accuracy and efficiency and help shorten the construction period.

[0050] S3. Fix the first steel insert 14 inside the side column 1. Install the assembled side column 1 on the channel steel adapter 3. Then, adjust the position by cooperating with the adjusting bolt 32 through the horizontal elongated hole 31 on the channel steel adapter 3. Finally, fix it.

[0051] S4, steel beam 5, second steel insert 22 and decorative cover plate 212 are processed in the workshop and transported to the construction site. One end of the steel beam 5 is connected and fixed to the side column 1 through a transition steel part 9, and the other end is welded to the middle column 2. An aluminum back plate 51 is installed on the back side of the middle column 2 so that the middle column 2 and the steel beam 5 are not exposed, ensuring the clean appearance of the curtain wall system.

[0052] S5. The processed glass panels 7 are installed into the glass groove aluminum 6 in sequence according to their numbers. The glass is fixed and sealed with glass strips and sealant. Then, the glass panels 7 and the central column 2 are finished and closed with decorative cover plate 212.

[0053] The present invention adopts a semi-prefabricated design, in which the side column 1 can be assembled and installed as a whole, and components such as the steel beam 5 can be completed in advance in the workshop, which reduces the amount of work and construction difficulty on the construction site, improves construction efficiency, and shortens the construction cycle.
